ITEM 3. KEY INFORMATION

D.Risk factors

Important factors that could cause actual financial, business, research or operating results to differ materially from expectations are disclosed in this annual report, including without limitation the following risk factors. Investors should carefully consider all the information set forth in the following risk factors and elsewhere in this document before deciding to invest in any of the Company’s securities. In addition to the risks listed below, we may be subject to other material risks that as of the date of this report are not currently known to us or that we deem immaterial at this time.

Risks relating to legal and regulatory matters

Product liability claims could adversely affect our business, results of operations and financial condition.

Product liability is a significant risk for any pharmaceutical company and our product liability exposure could increase given that liability claims relating to our businesses may differ with regard to their nature, scope and level, from the types of product liability claims that we have handled in the past. Substantial damages have been awarded by some jurisdictions and/or settlements agreed - notably in the United States and other common law jurisdictions - against pharmaceutical companies based on claims for injuries allegedly caused by the use of their products. Such claims can also be accompanied by consumer fraud claims by customers or third-party payers seeking reimbursement of the cost of the product.

We are currently defending a number of product liability claims (see Note D.22.a) to the consolidated financial statements included at Item 18 of this annual report) and there can be no assurance that we will be successful in defending these claims, or that it will not face additional claims in the future.

Often, establishing the full side effect profile of a pharmaceutical drug goes beyond data derived from preapproval clinical studies which may only involve several hundred to several thousand patients. Routine review and analysis of the continually growing body of post-marketing safety data, and clinical trials provide additional information - for example, potential evidence of rare, population-specific or long-term adverse events or of drug interactions that were not observed in preapproval clinical studies. This may cause product labeling to evolve over time, following interactions with regulatory authorities, including restrictions of therapeutic indications, new contraindications, warnings or precautions and occasionally even the suspension or withdrawal of a product marketing authorization. Following any of these events, pharmaceutical companies can face significant product liability claims.

Furthermore, we commercialize several devices (some of which use new technologies) which, if they malfunction, could cause unexpected damage and lead to product liability claims (see “- Breaches of data security, disruptions of information technology systems and cyber threats could result in financial, legal, business or reputational harm” below).

Although we continue to insure a portion of our product liability with third-party carriers, product liability coverage is increasingly difficult and costly to obtain, particularly in the United States. In the future, it is possible that self-insurance may become the sole commercially reasonable means available for managing the product liability financial risk of our pharmaceuticals and vaccines businesses (see “Item 4. Information on the Company - B. Business Overview - B.9. Insurance and Risk Coverage”). In cases where we self-insure, the legal costs that we would bear for handling such claims and potential indemnifications damage award to be paid to claimants could have a negative impact on our financial condition. Due to insurance conditions, even when we have insurance coverage, recoveries from insurers may not be totally successful due to insurance market limitations and exclusions. Moreover, insolvency of an insurer could affect our ability to recover claims on policies for which we have already paid a premium.

Product liability claims, regardless of their merits or the ultimate success of the Company’s defense, are costly, divert management’s attention, may harm our reputation and can impact the demand for our products. Substantial product liability claims could materially adversely affect our business, results of operations and financial condition.

Claims and investigations relating to compliance, ethics, competition law, marketing practices, pricing, human rights of workers, data protection and other legal matters could adversely affect our business, results of operations and financial condition.

Our industry is heavily regulated. We are obligated to comply with the laws of all countries in which we operate. However, legal requirements may vary from country to country and new requirements are imposed on us from time to time. Governments and regulatory authorities around the world have been strengthening implementation and enforcement activities in recent years, including in relation to anti-bribery, anti-corruption and ethical requirements with respect to medical and scientific research, respect of human rights of workers and data protection legislation. We have adopted a Code of Ethics that requires employees to comply with applicable laws and regulations, as well as the specific principles and rules of conduct set forth in the Code. We also have policies and procedures designed to help ensure that we, our officers, employees, agents, intermediaries and other third parties comply with applicable laws and regulations (including the US Foreign Corrupt Practices Act (“FCPA”), the UK Bribery Act, the OECD Anti-Bribery Convention, the French Anti-Corruption measures law (“Sapin II”) and the French duty of vigilance law and other anti-bribery laws and regulations).

Notwithstanding these efforts, failure to comply with laws and regulations (including as a result of a business partner’s breach) may occur and could result in liabilities for us and/or our management.

With respect to data protection legislation, the European General Data Protection Regulation (“GDPR”) has created a range of compliance obligations since 2018, when it came into force. Violations of the GDPR carry financial risks due to penalties for data breach or improper processing of personal data (including a possible fine of up to 4% of total worldwide annual turnover for the preceding financial year for the most serious infringements) and may also harm our reputation and our activities relying on personal data processing. Furthermore, some uncertainty remains with respect to the legal and regulatory environment for these evolving privacy and data protection laws.

Sanofi and certain of its subsidiaries are under investigation or could become the subject of additional investigations or proceedings by various government entities. We are currently defending ourselves in a number of lawsuits relating to pricing and marketing practices (including, for example, “whistleblower” litigation in the United States). We also face litigation and government investigations or audits, including allegations of corruption, claims related to employment matters, patent and intellectual property disputes, consumer law claims and tax audits. With respect to tax issues, due to the complexity of the fiscal environment, the ultimate resolution of any tax matter may result in payments greater




SANOFI / FORM 20-F 2019	3

ITEM 3. KEY INFORMATION

or lesser than amounts accrued. See “Item 8. Financial Information - A. Consolidated Financial Statements and Other Financial Information - Information on Legal or Arbitration Proceedings” and Note D.22. to our consolidated financial statements included at Item 18 of this annual report. In addition, responding to such investigations is costly and may divert management’s attention from our business.

Unfavorable outcomes in any of these matters, or in similar matters that may arise in the future, could preclude the commercialization of our products, harm our reputation, negatively affect the profitability of existing products and subject us to substantial fines, punitive damages, penalties and injunctive or administrative remedies, potentially leading to the imposition of additional regulatory controls, monitoring or self-reporting obligations, or exclusion from government reimbursement programs or markets, all of which could have a material adverse effect on our business, results of operations or financial condition.

As the outcomes of such proceedings are unpredictable, we may, after consideration of all relevant factors, decide to enter into settlement agreements to settle certain claims. Such settlements may involve significant monetary payments and/or criminal penalties, and may include admissions of wrongdoing and may require the conclusion of a Corporate Integrity Agreement or a Deferred Prosecution Agreement (in the United States), which is intended to regulate company behaviour for a specified number of years. For example, on February 28 , 2020, Sanofi US entered into a Civil Settlement with the United States Department of Justice and agreed to pay approximately $11.85 million to resolve allegations regarding certain charitable donations Sanofi US made to an independent patient assistance foundation that assisted patients being treated for Multiple Sclerosis. In connection with this settlement, Sanofi US also entered into a Corporate Integrity Agreement (“CIA”) with the Office of the Inspector General for the United States Department of Health and Human Services effective the same day which will require the Company to continue certain Compliance requirements in the US.

In addition, in September 2018, Sanofi reached a civil settlement with the US Securities and Exchange Commission (SEC) fully resolving the SEC’s investigation into possible violation of the US Foreign Corrupt Practices Act. Sanofi did not admit any wrongdoing in connection with the settlement but agreed to pay $25 million in penalties and also agreed to a two-year period of self-reporting on the effectiveness of its enhanced internal controls.

Our activities (including our products and manufacturing activities) are subject to significant government regulations and approvals, which are often costly and could result in adverse consequences to our business if we fail to anticipate the regulations, comply with them, maintain the required approvals, and/or adapt to changes in applicable regulations.

Obtaining a marketing authorization for a product is a long and highly regulated process requiring us to present extensive documentation and data to the relevant regulatory authorities either at the time of the filing of the application for a marketing authorization or later during its review. Each regulatory authority may impose its own requirements which can evolve over time. Each regulatory authority may also delay or refuse to grant approval even though a product has already been approved in another country. Regulatory authorities are increasingly strengthening their requirements on product safety and risk/benefit profile. All of these requirements, including post-marketing requirements, have increased the costs associated with maintaining marketing authorizations and achieving reimbursement for our products.

Moreover, to monitor our compliance with applicable regulations, the FDA, EMA, WHO and comparable national agencies in other jurisdictions routinely conduct inspections of our facilities, distribution centers, commercial activities and development centers and may identify potential deficiencies. More generally, if we fail to adequately respond to regulatory inspection observations identifying a deficiency during an inspection, or fail to comply with applicable regulatory requirements at all or within the targeted timeline, we could be subject to enforcement, remedial and/or punitive actions by the FDA (such as a Warning Letter or cease and desist orders), the EMA or other regulatory authorities. In addition, in order to comply with our duty to report adverse events and safety signals to regulatory authorities, we must regularly train our employees and third parties (such as external sales forces and distributor employees) on regulatory matters. If we fail to train these people, or fail to train them appropriately, or if they do not comply with contractual requirements, we may be exposed to the risk that safety events are not reported or not reported in a timely manner in breach of our reporting obligations.

In addition, all aspects of our business, including research and development, manufacturing, marketing, reimbursement, pricing and sales, are subject to extensive legislation and governmental regulation. Changes in applicable laws and the costs of compliance with such laws and regulations could have an adverse effect on our business.

In Europe, the implementation of new regulations on Medical Devices and In-Vitro Diagnostics (IVDs) that will apply respectively in May 2020 and May 2022, may cause delays in approvals (for new drug-device combination products and new drug-device combination products and new medical devices/IVDs), product discontinuation (for some legacy medical devices and IVDs), and non-compliance risks, due to increased requirements in terms of approval process, post-marketing surveillance, traceability and transparency.

For information regarding risks related to changes in proprietary rights rules and regulations, see “-We rely on our patents and other proprietary rights to provide exclusive rights to market certain of our products.If such patents and other rights were limited, invalidated or circumvented, our financial results could be adversely affected” below.

For information regarding risks related to changes in environmental rules and regulations, see “Management of the environmental impact of our past industrial activities may have a significant adverse effect on our results of operations” below.

We rely on our patents and other proprietary rights to provide exclusive rights to market certain of our products. If such patents and other rights were limited, invalidated or circumvented, our financial results could be adversely affected.

Through patent and other proprietary rights, such as data exclusivity or supplementary protection certificates in Europe, we hold exclusivity rights for a number of our research-based products. However, the protection that we are able to obtain varies in its duration and scope. Also patents and other proprietary rights do not always provide effective protection for our products.

For example, governmental authorities are increasingly looking to facilitate generic and biosimilar competition to existing products through new regulatory proposals intended to achieve, or resulting in, changes to the scope of patent or data exclusivity rights and use of accelerated regulatory pathways for generic and biosimilar drug approvals. Such regulatory proposals could make patent prosecution for new products more difficult and time consuming or could adversely affect the exclusivity period for our products.

ITEM 3. KEY INFORMATION

Moreover, manufacturers of generic products or biosimilars are increasingly seeking to challenge patent validity or coverage before the patents expire, and manufacturers of biosimilars or interchangeable versions of the products are seeking to have their version of the product approved before the exclusivity period ends. Furthermore, in an infringement suit against a third-party, we may not prevail and the decision rendered may not conclude that our patent or other proprietary rights are valid, enforceable or infringed. Our competitors may also successfully avoid our patents. Even in cases where we ultimately prevail in an infringement claim, legal remedies available for harm caused to us by infringing products may be inadequate to make us whole. Moreover, a successful result against a competing product for a given patent or in a specific country is not necessarily predictive of our future success against another competing product or in another country because of local variations in the patents and patent laws.

In addition, if we lose patent protection as a result of an adverse court decision or a settlement, we face the risk that government and private third-party payers and purchasers of pharmaceutical products may claim damages alleging they have over-reimbursed or overpaid for a drug. For example, in Australia, our patent on clopidogrel was ultimately held invalid. Following this decision, the Australian Government is seeking damages for its alleged over-reimbursement of clopidogrel drugs due to the preliminary injunction we had secured against the sale of generic clopidogrel during the course of the litigation.

In certain cases to terminate or avoid patent litigation, we or our collaboration partners may be required to obtain licenses from the holders of third-party intellectual property rights. Any payments under these licenses may reduce our profits from such products and we may not be able to obtain these licenses on favorable terms or at all.

Third parties may also request a preliminary or a permanent injunction in a country from a court of law to prevent us from marketing a product if they consider that we infringe their patent rights in that country. For example, Sanofi is currently party to patent infringement proceedings in several countries initiated against us and Regeneron by Amgen relating to Praluent ^® in which Amgen has requested injunctive relief (see Note D.22.b to the consolidated financial statements included at Item 18 of this annual report for more information). If third parties obtain a preliminary or permanent injunction or if we fail to obtain a required license for a country where valid third-party intellectual property rights as confirmed by a court of law exist, or if we are unable to alter the design of our technology to fall outside the scope of third-party intellectual property rights, we may be unable to market some of our products in certain countries, which may limit our profitability.

Furthermore, some countries may consider granting a compulsory license to a third party to use patents protecting an innovator’s product, which limits the value of the patent protection granted to such products.

We have increased the proportion of biological therapeutics in our pipeline relative to traditional small molecule pharmaceutical products. Typically, the development, manufacture, sale and distribution of biological therapeutics is complicated by third-party intellectual property rights (otherwise known as freedom to operate (FTO) issues), to a greater extent than for the development, manufacture, sale and distribution of small molecule therapeutics, because of the types of patents allowed by national patent offices. Further, our ability to successfully challenge third-party patent rights is dependent on the laws of national courts. In addition, we expect to face increasing competition from biosimilars in the future. With the accelerated regulatory pathways provided in the US and Europe for biosimilar drug approval, biosimilars can be a threat to the exclusivity of any biological therapeutics we sell or may market in the future and can pose the same issues as the small molecule generic threat described above. If a biosimilar version of one of our products were to be approved, it could reduce our sales and/or profitability of that product.

If our patents and/or proprietary rights to our products were limited or circumvented, our financial results could be adversely affected.

Risks relating to our business

The manufacture of our products is technically complex, and supply interruptions, product recalls or inventory losses caused by unforeseen events may reduce sales, adversely affect our operating results and financial condition, delay the launch of new products and negatively impact our image.

Many of our products are manufactured using technically complex processes requiring specialized facilities, trained and certified employees, highly specific raw materials and other production constraints; all of these elements as a whole are governed by extensive and complex regulations issued by governmental health authorities around the world. We must ensure that all manufacturing processes comply with current Good Manufacturing Practices (cGMP) and other applicable regulations, as well as with our own quality standards. Third parties supply us with a portion of our raw materials, active ingredients and medical devices, which exposes us to the risk of a supply shortage or interruption in the event that these suppliers are unable to manufacture our products in line with quality standards or if they experience financial difficulties. Epidemics and other public health crises, such as the ongoing novel coronavirus which has emerged since December 2019 in China, expose us to the risks of a slowdown or temporary suspension in the production of our active pharmaceutical ingredients (API), raw materials and some of our products. A certain number of our API and raw materials are produced in China. We also have a production site for pharmaceutical products in Hangzhou (China) and a production site for API in Singapore. Any prolonged restrictive measures put in place in order to control an outbreak of contagious disease or other adverse public health development, in China or any of our principal production sites, may have a material and adverse effect on our manufacturing operations . Any of these factors could adversely affect our business, operating results or financial condition (see “Item 4. Information on the Company - B. Business Overview - B.8. Production and Raw Materials” for a description of these outsourcing arrangements).

We must also be able to produce sufficient quantities of our products to satisfy demand. We may have difficulties transforming and adapting our existing plants to manufacture new products, including biologics, and scaling up production of our products currently under development once they are approved. Furthermore, our biological products, in particular, are subject to the risk of manufacturing stoppages or the risk of loss of inventory because of the difficulties inherent in the processing of biological materials and the potential difficulties in accessing adequate amounts of raw materials meeting required standards. In addition, specific storage and distribution conditions are required for many biological products (for example, cold storage is required for certain vaccines, insulin-based products and some hemophilia products). These production difficulties may also be encountered during testing, which is a mandatory requirement prior to drug products being released. For example, in 2018 in China, we encountered supply constraints of Pentaxim ^® vaccine due to problems with the supplier of a raw material used in the formulation of Pentaxim ^® for China. As a result we had to find an alternative raw material to meet Chinese requirements.

Some of our production sites are located in areas exposed to natural disasters such as floods (for example our facility at Le Trait, France), earthquakes and hurricanes. Such disasters could be exacerbated by global warming. In the event of a major disaster we could experience severe destruction or interruption of our operations and production capacity at these sites.




SANOFI / FORM 20-F 2019	5

ITEM 3. KEY INFORMATION

The complexity of these processes, as well as standards required for the manufacture of our products, subject us to risks because the investigation and remediation of any identified or suspected problems can cause production delays, substantial expense, product recalls or lost sales and inventories, and delay the launch of new products; this could adversely affect our operating results and financial condition, and cause reputational damage and the risk of product liability (see - “Product liability claims could adversely affect our business, results of operations and financial condition” above).

When manufacturing disruptions occur, we may not have alternate manufacturing capacity, particularly for certain biologics. In the event of manufacturing disruptions, our ability to use backup facilities or set up new facilities is more limited because biologics are more complex to manufacture and generally require dedicated facilities. Even though we aim to have backup sources of supply whenever possible, including by manufacturing backup supplies of our principal active ingredients at additional facilities when practicable, we cannot be certain they will be sufficient if our principal sources become unavailable. Switching sources and manufacturing facilities requires significant time and prior approval by health authorities.

Supply shortages generate even greater negative reactions when they occur with respect to life saving medicines with limited or no viable therapeutic alternatives. Shortages of specific products can have a negative impact on the confidence of patients, customers and professional healthcare providers, the image of Sanofi and may lead to lower product revenues.

The pricing and reimbursement of our products is increasingly affected by decisions of governments and other third parties and cost reduction initiatives.

The commercial success of our existing products and our product candidates depends in part on their pricing and the conditions under which our products are reimbursed. Our products continue to be subject to increasing price and reimbursement pressure due, inter alia, to:


▪	price controls imposed by governments in many countries;


▪	increased public attention to the price of drugs and drug price increases, with growing public calls for us to justify the launch prices of all our products;


▪	increased use of tendering and grouped purchasing to exert price pressure through competitive access to large parts of the market or markets;


▪	rem oval of a number of drugs from government reimbursement schemes (for example products determined to be less cost-effective than alternatives);


▪	decreased reimbursement rates for drugs, and increased difficulty in obtaining and maintaining satisfactory drug reimbursement rates;


▪	partial reimbursement of patient populations within a labelled indication;


▪	increased use of cost containment policies (including budget limitations) related to health expenses;


▪	governmental and private health care provider policies that favor prescription of generic medicines or substitution of branded products with generic medicines;


▪	more demanding evaluation criteria applied by Health Technology Assessment (HTA) agencies when considering whether to cover new drugs at a certain price level;


▪	more governments using international reference pricing to set or manage the price of drugs based on an external benchmark of a product’s price in other countries;


▪	aggressive pricing strategies by some of our competitors; and


▪	entry of ne w consumer healthcare competitors offering online sales.

In addition to the pricing pressures they exert, governmental and private third-party payers and purchasers of pharmaceutical products may reduce volumes of sales by restricting access to formularies (including exclusive formularies), managing prescribing via various conditions (including prior authorizations and step edits) or otherwise discouraging physicians from prescribing our products (see also “- The concentration of the US market exposes us to greater pricing pressure” below).

In the United States, which accounted for 35.3 % of our net sales in 2019, the Affordable Care Act (ACA) has increased the government’s role with respect to price, reimbursement, and coverage levels for healthcare services and products. This law also imposed rebates and fees on pharmaceutical companies. In 2018, the Trump Administration published its American Patients First proposal, which indicates its plans to investigate the ACA’s impact on private market drug prices and potentially alter the ACA taxes and rebates for Medicaid and Medicaid managed care organizations. In December 2018, a federal judge for the Northern District of Texas, Fort Worth Division, issued a ruling declaring the ACA unconstitutional. An appeal was filed with the Federal Court of Appeals for the Fifth Circuit. Once a decision is issued, litigation may continue, including possibly a further appeal to the United States Supreme Court. Included in the many parts of the ACA that could potentially be affected by the continued litigation is the Biologics Price Competition and Incentives Act. In addition to further judicial review of the ACA, the Trump Administration and other United States federal and state officials are continuing to focus on the cost of health coverage, health care and pharmaceuticals, although future policy or the timing of any changes remains unclear, creating significant risks for the sector. At the federal level, legislation like the Bipartisan Budget Act of 2018 amended the ACA, effective January 1, 2019, to close the coverage gap in most Medicare drug plans, and also increased in 2019 the percentage by which a drug manufacturer must discount the cost of prescription drugs from 50 percent under current law to 70 percent. Legislation that would affect the price for drugs under the Medicare program has been voted out of committee and is awaiting a vote in the House of Representatives, and different legislation that would require the payment of rebates to Medicare if annual drug price increases exceed overall inflation. Further, federal regulatory reform intended to reduce costs of drugs furnished under Medicare and Medicare Advantage plans through utilization management tools such as step therapy, and to increase price transparency for such drugs, became effective on January 1, 2020. The federal government is evaluating permitting the importation of certain drugs, which would place additional pressure on drug pricing. Since 2017, at least nine states have enacted and an additional 25 states have proposed legislation which will require price transparency and reporting of certain manufacturer information. This trend is

ITEM 3. KEY INFORMATION

anticipated to continue in 2020, where legislation is expected regarding pricing transparency, marketing, access to drugs and other measures related to pricing.

We also encounter cost containment issues in countries outside the United States. In certain countries, including countries in the European Union, China and Canada, the coverage of prescription drugs, and pricing and levels of reimbursement, are subject to governmental control. For example, in Europe various authorities are developing the use of tenders for expensive products and are considering joint procurement mechanisms to negotiate lower prices. In China, the health authorities continue to develop measures around post loss-of-exclusivity (“LOE”) brands including the selection of generics validated through bioequivalence. In September 2019, the health authorities expanded a pilot procurement system (volume-based procurement or “VBP”) launched in 2018 - which targeted post LOE brands with generics demonstrating bioequivalence in four municipalities and seven major cities - to a nationwide tender system. With respect to our products, the Plavix ^® and Aprovel ^® product families were included in the national tender but due to price adjustments, net sales from the Plavix ^® and Aprovel ^® product families are expected to decline by 50% in China for 2020.

In addition, while we are trying to predict the level of reimbursement and related restrictions for our product candidates, external events and unexpected decisions can occur that go against our expectations which could materially and adversely affect our sales, profits and financial results more generally.

The concentration of the US market exposes us to greater pricing pressure.

In the United States, price is increasingly important to managed care organizations (MCOs) and pharmacy benefit managers (PBMs). As the MCOs/PBMs grow in size following market consolidation, pharmaceutical companies have faced increased pressure in discounting and usage negotiations, and competition among pharmaceutical companies to have their products included in the payers’ formularies is robust. This can lead to price discounts or rebates in connection with the placement of products.

Exclusion of one of our drugs from a formulary can significantly reduce sales in the MCO/PBM patient population (for instance, effective 2017 Lantus ^® /Toujeo ^® were excluded from certain template formularies covering millions of people).

Also, some payers in the United States have put in place significant restrictions on the usage of Praluent ^® , which has resulted in significant out-of-pocket expenditures for patients. As a result, in 2018 we reduced the net price of Praluent ^® for US payers that agreed to reduce burdensome access barriers for patients, which was reflected in 2019 by a sales decrease of 30.5% .

Due to these pressures on our prices, our revenues and margins are, and could continue to be, negatively affected.

Breaches of data security, disruptions of information technology systems and cyber threats could result in financial, legal, business or reputational harm.

Our business depends heavily on the use of interdependent information technology systems, including internet-based systems and digital tools. Certain key areas such as research and development, production and sales are to a large extent dependent on our information systems (including cloud-based computing) or those of third-party providers (including for the storage and transfer of critical, confidential, sensitive or personal information regarding our patients, clinical trials, vendors, customers, employees, collaborators and others).

We and our third-party service providers, suppliers, contract manufacturers, distributors or other contracting third parties use secure information technology systems for the protection of data and threat detection. Like many companies, we may experience certain of the following events: breakdown, service disruption or impairment, data loss or deterioration in the event of a system malfunction, or increasing threat of data theft or corruption in the event of a cyber-attack, security breach, industrial espionage attacks or insider threat attacks.

Each of these events could negatively impact important processes, such as scientific research and clinical trials, the submission of outcomes to health authorities for marketing authorizations, the functioning of production processes and the supply chain, compliance with legal requirements and other key activities, including Sanofi’s employees’ ability to communicate between themselves as well as with third parties (see also “Product liability claims could adversely affect our business, results of operations and financial condition” above). This could result in material financial, legal, business or reputational harm.

Although we maintain insurance coverage, this insurance may not be sufficiently available in the future to cover the financial, legal, business or reputational losses that may result from an interruption or breach of our systems. For example, certain types of cyber-attacks could be considered as an Act of War subject to insurance exclusion.

Our research and development efforts may not succeed in adequately renewing our product portfolio.

Discovering and developing a new product is a costly, lengthy and uncertain process. To be successful in the highly competitive pharmaceutical industry, we must commit substantial resources each year to research and development in order to develop new products to compensate for decreasing sales of products facing patent expiration and termination of regulatory data exclusivity, introduction of lower-priced generics, or competition from new products of competitors that are perceived as being superior or equivalent to our products. We must pursue both early stage research and early and late development stages in order to propose a sustainable and well-balanced portfolio of products. In 2019, we spent € 6,018 million on research and development, amounting to 16.7 % of our net sales.

In December 2019, as part of our strategic framework we announced our intent to prioritize six potentially transformative therapies in areas of high unmet patient need: fitusiran and BIVV001 (hemophilia); SERD (breast cancer); venglustat (rare diseases); nirsevimab (respiratory syncytial virus); and BTKi (multiple sclerosis). We also announced our intent to discontinue our research in diabetes and cardiovascular (DCV). However, we may choose the wrong areas of research or products of our portfolio, and may not be able to improve our research productivity sufficiently to sustain our pipeline. In addition, numerous companies are working on the same targets and a product considered as promising at the beginning of its development may become less attractive if a competitor addressing the same unmet need reaches the market earlier. There can be no assurance that any of our product candidates will be proven safe or effective (see “Item 4. Information on the Company - B. Business Overview - B.5. Global Research & Development”). Over these research and development cycles spanning several years, there is a substantial risk at each stage of development - including clinical trials - that we will not achieve our goals of safety and/or efficacy and that we will have to abandon a product in which we have invested substantial amounts of money and human resources. More and more trials are designed with clinical endpoints of superiority; failure to achieve those endpoints could damage the product’s reputation and our overall development program.




SANOFI / FORM 20-F 2019	7

ITEM 3. KEY INFORMATION

Decisions concerning the studies to be carried out can have a significant impact on the marketing strategy for a given product. Multiple in-depth studies can demonstrate that a product has additional benefits, facilitating the product’s marketing, but such studies are expensive and time consuming and may delay the product’s submission to regulatory authorities for approval.

In addition, following (or in some cases contemporaneously with) the marketing authorization, the dossier is also submitted to governmental agencies and/or national or regional third-party payers - Health Technology Assessment (HTA) bodies - for review. These HTA bodies evaluate evidence on the value of the new product, assess the medical need it serves and provide recommendations on the corresponding reimbursement. Such analyses may require additional studies, including comparative studies, which may effectively delay marketing, change the population which the new product treats, and add costs to its development. Our continuous investments in research and development for future products and for the launches of newly registered molecules could therefore result in increased costs without a proportionate increase in revenues, which would negatively affect our operating results and profitability.

Lastly, there can be no assurance that all the products approved or launched will achieve commercial success.

A substantial share of the revenue and income of Sanofi depends on the performance of certain flagship products.

As part of the presentation of our strategy in December 2019 we announced our intent to prioritize our activities on growth drivers including Dupixent ^® and our Vaccines operations, which we have identified as key growth drivers. Nevertheless market expansion and new launches of medicines and vaccines may not deliver the expected benefits.

We may also encounter failures or delays in our launch strategy (in terms of timing, pricing, market access, marketing efforts and dedicated sales forces) of products that may not deliver the expected benefits. The competitive environment for a given product may also have changed by the time of the actual launch, modifying our initial expectations. The need to prioritize the allocation of resources may also cause delays in or hamper the launch or expansion of some of our products.

Also we currently generate a substantial share of our revenues from the sale of certain key products (see “Item 5. Operating and Financial Review and Prospects - Results of Operations - Year ended December 31, 2019 compared with year ended December 31, 2018 - Net Sales - Pharmaceuticals segment”).

Among our flagship products, Lantus ^® , Lovenox ^® and Plavix ^® already face generic competition on the market. Lantus ^® is particularly important; it was Sanofi’s leading product with revenues of €3,012 million in 2019, representing 8.3% of our net sales for the year. Aubagio ^® , following a settlement agreement entered into in 2017, is expected to face generic competition starting from March 2023.

More generally, an expiration of effective intellectual property protections for our products typically results in the market entry of one or more lower-priced generic competitors, often leading to a rapid and significant decline in revenues on those products (for information regarding ongoing patent litigation see Note D.22.b) to the consolidated financial statements included at Item 18 of this annual report).

The introduction of a generic product results in adverse price and volume effects for our branded or genericized products. For example, although we do not believe it is possible to state with certainty what level of net sales would have been achieved in the absence of generic competition, a comparison of our consolidated net sales for 2019 and 2018 for products affected by generic and biosimilar competition shows a loss of €912 million of net sales on a reported basis (see “Item 5. Operating and Financial Review and Prospects - A.1.2. Impacts of Competition from Generics and Biosimilars”). However, other parameters may have contributed to the loss of sales, such as a fall in the average price of certain products (e.g. Lantus ^® ). Furthermore, in general, if one or more of our flagship products were to encounter problems (such as material product liability litigation, unexpected side effects, or product recalls), the adverse impact on our business, results of operations and financial condition could be significant.

We rely on third parties for the discovery, manufacture and marketing of some of our products.

Our industry is both highly collaborative and competitive, whether in the discovery and development of new products, in-licensing, the marketing and distribution of approved products, or manufacturing activities. We expect that we will continue to rely on third parties for key aspects of our business and we need to ensure our attractiveness as a potential partner.

We conduct a number of significant research and development programs and market some of our products in collaboration with other biotechnology and pharmaceutical companies. For example, we currently have a global strategic collaboration with Regeneron on monoclonal antibodies. In immuno-oncology, we have a global collaboration with Regeneron for the joint development and commercialization of cemiplimab, a programmed cell death protein 1 (PD-1) inhibitor antibody. We have also an immuno-oncology discovery and development agreement with Regeneron on the development of two clinical-stage bispecific antibody programs targeting respectively (i) BCMA and CD3 and (ii) MUC16 and CD3 (see “Item 4. Information on the Company - B. Business Overview”). Dupixent ^® has been developed and commercialized in collaboration with Regeneron. Also, in December 2019, Sanofi and Regeneron announced their intention to restructure their antibody collaboration related to Kevzara ^® (sarilumab) and Praluent ^® (alirocumab) (see "Item 5. Financial Presentation of Alliances - A.1.7.1/ Alliance Arrangements with Regeneron"). Finally, we may also rely on partners to design and manufacture medical devices, notably for the administration of our products.

As regards products recently launched or under development for which we have a collaboration with partners, the terms of the applicable alliance agreement may require us to share profits and losses arising from commercialization of such products with our partners. This differs from the treatment of revenue and costs generated by other products for which we have no alliance agreement, and such profit sharing may deliver a lower contribution to our financial results.

We could also be subject to the risk that we may not properly manage the decision-making process with our partners. Decisions may also be under the control of or subject to the approval of our collaboration partners, who may have views that differ from ours. We are also subject to the risk that our partners may not perform effectively, which could have a detrimental effect when the performance of certain key tasks or functions is the responsibility of our collaboration partners. Failures in the development process or differing priorities may adversely affect the activities conducted through the collaboration arrangements.

We could face conflicts or difficulties with these partners during the course of these agreements or at the time of their renewal or renegotiation. All these events may affect the development, the launch and/or the marketing of certain of our products or product candidates and may cause a decline in our revenues or otherwise negatively affect our results of operations.

ITEM 3. KEY INFORMATION

We are subject to the risk of non-payment by our customers ⁽¹⁾ .

We run the risk of delayed payments or even non-payment by our customers, which consist principally of wholesalers, distributors, pharmacies, hospitals, clinics and government agencies. This risk is accentuated by recent concentrations among distributors, as well as by uncertainties around global credit and economic conditions, in particular in emerging markets. The United States poses particular customer credit risk issues because of the concentrated distribution system: our three main customers represented respectively 8% , 5% and 3% of our consolidated net sales in 2019. We are also exposed to large wholesalers in other markets, particularly in Europe. Although we assign some of our receivables to factoring companies or banks, an inability of one or more of these wholesalers to honor their debts to us could adversely affect our financial condition (see Note D.34. to our consolidated financial statements included at Item 18 of this annual report).

In some countries, some customers are public or subsidized health systems. The economic and credit conditions in these countries may lead to an increase in the average length of time needed to collect on accounts receivable or the ability to collect 100% of receivables outstanding. Because of this context, we may need to reassess the recoverable amount of our debts in these countries during future financial years (see also “Item 5. Operating and Financial Review and Prospects - Liquidity and Capital Resources - Liquidity.”).

Global economic conditions and an unfavorable financial environment could have negative consequences for our business ⁽²⁾ .

Over the past several years, growth of the global pharmaceutical market has become increasingly tied to global economic growth. In this context, a substantial and lasting slowdown of the global economy, major national economies or emerging markets could negatively affect growth in the global pharmaceutical market and, as a result, adversely affect our business.

Unfavorable economic conditions have reduced the sources of funding for national social security systems, leading to austerity measures including heightened pressure on drug prices, increased substitution of generic drugs, and the exclusion of certain products from formularies.

Further, our net sales may be negatively impacted by the continuing challenging global economic environment, as high unemployment, increases in cost-sharing, and lack of developed third-party payer systems in certain regions may lead some patients to switch to generic products, delay treatments, skip doses or use other treatments to reduce their costs. In the United States there has been a significant increase in the number of beneficiaries in the Medicaid program, under which sales of pharmaceuticals are subject to substantial rebates and, in many US states, to formulary restrictions limiting access to brand-name drugs, including ours. Also, employers may seek to transfer a greater portion of healthcare costs to their employees due to rising costs.

Our Consumer Healthcare business could also be adversely impacted by difficult economic conditions that limit the financial resources of our customers.

If economic conditions worsen, or in the event of default or failure of major players including wholesalers or public sector buyers financed by insolvent states, our financial situation, the results of our operations and the distribution channels of our products may be adversely affected. See also “We are subject to the risk of non-payment by our customers” above.

The United Kingdom left the European Union effective January 31, 2020 (“Brexit”). Given the lack of comparable precedent, it is unclear what financial, trade, regulatory and legal implications the withdrawal of the United Kingdom from the European Union will have. Brexit creates global economic and financial uncertainty, which may cause, among other consequences, volatility in exchange rates and interest rates and changes in regulations. In addition, the move of the headquarters of the European Union’s health authority, the EMA, from the United Kingdom to the Netherlands has impaired the work of the EMA and could also delay new drug approvals in the European Union. However, our internal Brexit Task Force has developed and deployed, and is continuing to develop and deploy, contingency measures aiming at avoiding interruption of supply to patients. As a result, we currently do not believe that these effects will have a material impact on our financial situation or the results of our operations. As of December 31, 2019, the United Kingdom represented 1.7% of our consolidated net sales in the 2019 fiscal year and less than 1% of our total assets.

The increasing use of social media platforms and new technologies present risks and challenges for our business and reputation.

We increasingly rely on social media, new technologies and digital tools to communicate about our products and diseases or to provide health services. The use of these media requires specific attention, monitoring programs and moderation of comments. Political and market pressures may be generated by social media because of rapid news cycles. This may result in commercial harm, overly restrictive regulatory actions and erratic share price performance. In addition, unauthorized communications, such as press releases or posts on social media, purported to be issued by Sanofi, may contain information that is false or otherwise damaging and could have an adverse impact on our image and reputation and on our stock price. Negative or inaccurate posts or comments about Sanofi, our business, directors or officers on any social networking website could seriously damage our reputation. In addition, our employees and partners may use social media and mobile technologies inappropriately, which may give rise to liability for Sanofi, or which could lead to breaches of data security, loss of trade secrets or other intellectual property or public disclosure of sensitive information. Such uses of social media and mobile technologies could have an adverse effect on our reputation, business, financial condition and results of operations.

ITEM 3. KEY INFORMATION

Risks relating to Sanofi’s structure and strategy

We may fail to successfully identify external business opportunities or realize the anticipated benefits from our strategic investments or divestments.

We pursue a strategy of selective acquisitions, in-licensing and collaborations in order to reinforce our pipeline and portfolio. We are also proceeding to selective divestments to focus on key business areas. The implementation of this strategy depends on our ability to identify transaction opportunities, mobilize the appropriate resources in order to enter into agreements in a timely manner, and execute these transactions on acceptable economic terms. Moreover, entering into in-licensing or collaboration agreements generally requires the payment of significant “milestones” well before the relevant products reach the market, without any assurance that such investments will ultimately become profitable in the long term (see Note D.21.1. to the consolidated financial statements included at Item 18 of this annual report and also - “We rely on third parties for the discovery, manufacture and marketing of some of our products” above).

For newly acquired activities or businesses our growth objectives could be delayed or ultimately not realized, and expected synergies could be adversely impacted if:


▪	we are unable to quickly or efficiently integrate those activities or businesses;


▪	key employees leave; or


▪	we hav e higher than anticipated integration costs.

For instance, we had to book a €2.8 billion impairment on Eloctate ^® , acquired through the Bioverativ acquisition completed in 2018, due to revision of sales projections.

For divestments, their financial benefit could be impacted if we face significant financial claims or significant post-closing price adjustments. We may miscalculate the risks associated with business development transactions at the time they are made or not have the resources or ability to access all the relevant information to evaluate them properly, including with regard to the potential of research and development pipelines, manufacturing issues, compliance issues, or the outcome of ongoing legal and other proceedings. It may also take a considerable amount of time and be difficult to implement a risk analysis and risk mitigation plan after the acquisition of an activity or business is completed due to lack of historical data. As a result, risk management and coverage of such risks, particularly through insurance policies, may prove to be insufficient or ill-adapted.

Because of the active competition among pharmaceutical groups for such business development opportunities, there can be no assurance of our success in completing these transactions when such opportunities are identified.

The globalization of our business exposes us to increased risks in specific areas.

Emerging markets represented 30.2 % of our sales in 2019. As part of the presentation of our strategy in December 2019, we identified our strong presence in China among our core drivers, with revenue amounting to 7.5 % of our net sales in 2019.

Nevertheless, the difficulties in operating in emerging markets, a significant decline in the anticipated growth rate or an unfavorable movement of the exchange rates of currencies against the euro could impair our ability to take advantage of growth opportunities and could adversely affect our business, results of operations or financial condition. For instance, while it is not possible as of the date of this report to predict the economic impact and the magnitude of the ongoing coronavirus epidemic which started in China in December 2019, if a long-lasting epidemic and prolonged restrictive measures to control the outbreak were to result in an economic slowdown in any of our targeted markets such as China, it would reduce our sales due to lower healthcare spending on other diseases and fewer promotional activities, and could significantly impact our business operations. Such epidemics or other public health crises could also pose risks to the health and safety of our employees. Furthermore, it is not possible to predict if the current health crisis will impact the Chinese healthcare system, or that of any other affected jurisdiction, or to what extent (see also “- Global economic conditions and an unfavorable financial environment could have negative consequences for our business” above).

Emerging markets also expose us to more volatile economic conditions, political instability (including a backlash in certain areas against free trade), competition from multinational or locally based companies that are already well established in these markets, the inability to adequately respond to the unique characteristics of emerging markets (particularly with respect to their underdeveloped judicial systems and regulatory frameworks), difficulties in recruiting qualified personnel or maintaining the necessary internal control systems, potential exchange controls, weaker intellectual property protection, higher crime levels (particularly with respect to counterfeit products), and compliance issues including corruption and fraud (see particularly “- Claims and investigations relating to compliance, ethics, competition law, marketing practices, pricing, human rights of workers, data protection and other legal matters could adversely affect our business, results of operations and financial condition” above).

We may fail to develop or take advantage of digitalization.

We have undertaken a number of digital initiatives (such as the opening in October 2019 of our Framingham digitally enabled manufacturing facility in the US and Darwin, our real-world data platform). However there is no guarantee that our efforts toward a digital transformation will succeed. More generally, we may fail to capture the benefits of digital at an appropriate cost, in a timely manner and/or enter into appropriate collaborations. Competitors, including new entrants such as tech companies, may outpace us in this fast-moving area. If we fail to adequately integrate digitalization into our organization and business model, we could lose patients and market share. This could have an adverse impact on our business, prospects and results of operations.

We may fail to accelerate our efficiency.

As part of our strategy we announced our intent to improve our operating efficiencies to fund growth and expand our business operating income margin. We have also announced savings initiatives that we expect will generate €2 billion of savings by 2022 to fund investment in our key growth drivers, to accelerate priority pipeline projects and to support the expansion of our BOI margin. Nevertheless there is no guarantee that we will be able to fully deliver these operating efficiencies within the targeted timeline or generate the expected benefits.

ITEM 3. KEY INFORMATION

Our success depends in part on our senior management team and other key employees and our ability to attract, integrate and retain key personnel and qualified individuals in the face of intense competition.

We depend on the expertise of our senior management team and other key employees. In 2019, there were 2,066 “Senior Leaders” within Sanofi, including Executive Committee members and other executives. In addition, we rely heavily on recruiting and retaining talented people to help us meet our strategic objectives. We face intense competition for qualified individuals for senior management positions, or in specific geographic regions or in specialized fields such as clinical development, biosciences and devices, or digital and artificial intelligence. Our ability to hire qualified personnel also depends in part on our ability to reward performance, incentivize our employees and to pay competitive compensation. Laws and regulations on executive compensation may restrict our ability to attract, motivate and retain the required level of talented people. The inability to attract, integrate and/or retain highly skilled personnel, in particular those in leadership positions, may weaken our succession plans, may materially adversely affect the implementation of our strategy and our ability to meet our strategic objectives, and could ultimately adversely impact our business or results of operations.

Environmental and safety risks of our industrial activities

Risks from the handling of hazardous materials could adversely affect our results of operations.

Manufacturing activities, such as the chemical manufacturing of the active ingredients in our products and the related storage and transportation of raw materials, products and waste, expose us to the risks of industrial accidents that may lead to discharges or releases of toxic or pathogen substances or other events that can cause personal injury, property damage and environmental contamination, and may result in the shutdown of affected facilities and/or the imposition of civil, administrative, criminal penalties and/or civil damages.

The occurrence of an industrial accident may significantly reduce the productivity and profitability of a particular manufacturing facility and adversely affect our operating results and reputation. Although we maintain property, business interruption and casualty insurance that we believe is in accordance with customary industry practices, this insurance may not be adequate to fully cover all potential hazards incidental to our business.

Management of the environmental impact of our past industrial activities may have a significant adverse effect on our results of operations.

The environmental laws of various jurisdictions impose actual and potential obligations on our Company to remediate contaminated sites. These obligations may relate to sites:


▪	that we currently own or operate;


▪	that we formerly owned or operated; or


▪	where w aste from our operations was disposed.

These environmental remediation obligations could reduce our operating results. Sanofi accrues provisions for remediation when our management believes the need is probable and that it is reasonably possible to estimate the cost. See “Item 4. Information on the Company - B. Business Overview - B.10. Health, Safety and Environment (HSE)” for additional information regarding our environmental policies. In particular, our provisions for these obligations may be insufficient if the assumptions underlying these provisions prove incorrect or if we are held responsible for additional, currently undiscovered contamination. These judgments and estimates may later prove inaccurate, and any shortfalls could have an adverse effect on our results of operations and financial condition. For more detailed information on environmental issues, see “Item 4.Information on the Company - B. Business Overview - B.10. Health, Safety and Environment (HSE) and Notes B.12 and D.19.3 to the consolidated financial statements”.

We are or may become involved in claims, lawsuits and administrative proceedings relating to environmental matters. Some current and former Sanofi subsidiaries have been named as “potentially responsible parties” or the equivalent under the US Comprehensive Environmental Response, Compensation and Liability Act of 1980, as amended (also known as “Superfund”), and similar statutes in France, Germany, Italy, Brazil and elsewhere. As a matter of statutory or contractual obligation, we and/or our subsidiaries may retain responsibility for environmental liabilities at some of the sites of our predecessor companies, or of subsidiaries that we demerged, divested or may divest. We have disputes outstanding regarding certain sites no longer owned by the Company. An adverse outcome in such disputes might have a significant adverse effect on our operating results. See Note D.22.d) to the consolidated financial statements included at Item 18 of this annual report and “Item 8. Financial Information - A. Consolidated Financial Statements and Other Financial Information - Information on Legal or Arbitration Proceedings”.

Environmental regulations are evolving . For example, in Europe, new or evolving regulatory regimes include REACH, CLP/GHS, SEVESO, IPPC/IED, the Waste Framework Directive, the Emission Trading Scheme Directive, the Water Framework Directive, the Directive on Taxation of Energy Products and Electricity and several other regulations aimed at preventing global warming. Stricter environmental, safety and health laws and enforcement policies could result in substantial costs and liabilities to our Company and could subject our handling, manufacture, use, reuse or disposal of substances or pollutants, site restoration and compliance to more rigorous scrutiny than is currently the case. Consequently, compliance with these laws could result in capital expenditures as well as other costs and liabilities, thereby adversely affecting our business, results of operations or financial condition.




SANOFI / FORM 20-F 2019	11

ITEM 3. KEY INFORMATION

Risks related to financial markets ⁽¹⁾

Fluctuations in currency exchange rates could adversely affect our results of operations and financial condition.

Because we sell our products in numerous countries, our results of operations and financial condition could be adversely affected by fluctuations in currency exchange rates. We are particularly sensitive to movements in exchange rates between the euro and the US dollar, the Japanese yen, the Chinese Yuan and to currencies in emerging markets. In 2019 , 35.3 % of our net sales were generated in the United States; 22.7 % in Emerging Markets other than China (see the definition in “Item 5. Operating and Financial Review and Prospects – A/ Operating results”), including countries that are, or may in future become, subject to exchange controls; 7.5 % in China; and 5.3 % in Japan. While we incur expenses in those currencies, the impact of currency exchange rates on these expenses does not fully offset the impact of currency exchange rates on our revenues. As a result, currency exchange rate movements can have a considerable impact on our earnings. When deemed appropriate and when technically feasible, we enter into transactions to hedge our exposure to foreign exchange risks. These efforts, when undertaken, may fail to offset the effect of adverse currency exchange rate fluctuations on our results of operations or financial condition. For more information concerning our exchange rate exposure, see “Item 11. Quantitative and Qualitative Disclosures about Market Risk.”

Risks relating to an investment in our shares or ADSs

Foreign exchange fluctuations may adversely affect the US dollar value of our ADSs and dividends (if any).

Holders of ADSs face exchange rate risk. Our ADSs trade in US dollars and our shares trade in euros. The value of the ADSs and our shares could fluctuate as the exchange rates between these currencies fluctuate. If and when we pay dividends, they would be denominated in euros. Fluctuations in the exchange rate between the euro and the US dollar will affect the US dollar amounts received by owners of ADSs upon conversion by the depositary of cash dividends, if any. Moreover, these fluctuations may affect the US dollar price of the ADSs on the Nasdaq Global Select Market (Nasdaq) whether or not we pay dividends, in addition to any amounts that a holder would receive upon our liquidation or in the event of a sale of assets, merger, tender offer or similar transaction denominated in euros or any foreign currency other than US dollars.

Persons holding ADSs rather than shares may have difficulty exercising certain rights as a shareholder.

Holders of ADSs may have more difficulty exercising their rights as a shareholder than if they directly held shares. For example, if we issue new shares and existing shareholders have the right to subscribe for a pro rata portion of the new issuance, the depositary is allowed, at its own discretion, to sell this right to subscribe for new shares for the benefit of the ADS holders instead of making that right available to such holders. In that case, ADS holders could be substantially diluted. Holders of ADSs must also instruct the depositary how to vote their shares. Because of this additional procedural step involving the depositary, the process for exercising voting rights will take longer for holders of ADSs than for holders of shares. ADSs for which the depositary does not receive timely voting instructions will not be voted at any meeting.

Sales of our shares may cause the market price of our shares or ADSs to decline.

Sales of large numbers of our shares, or a perception that such sales may occur, could adversely affect the market price for our shares and ADSs. To our knowledge, L’Oréal, our largest shareholder, is not subject to any contractual restrictions on the sale of the shares it holds in our Company. L’Oréal does not consider its stake in our Company as strategic.

Our largest shareholder owns a significant percentage of the share capital and voting rights of Sanofi.

As of December 31, 2019 , L’Oréal held approximately 9.43% of our issued share capital, accounting for approximately 16.82% of the voting rights (excluding treasury shares) of Sanofi. See “Item 7. Major Shareholders and Related Party Transactions – A. Major Shareholders.” Affiliates of L’Oréal currently serve on our Board of Directors. To the extent L’Oréal continues to hold a large percentage of our share capital and voting rights, it will remain in a position to exert greater influence in the appointment of the directors and officers of Sanofi and in other corporate actions that require shareholders’ approval.

ITEM 3. KEY INFORMATION

Risks relating to our Contingent Value Rights (CVRs)

In addition to the risks relating to our shares, CVR holders are subject to additional risks.

In connection with our acquisition of Genzyme, we issued CVRs under a CVR agreement entered into by and between us and American Stock Transfer & Trust Company, the trustee (see also Note D.18. to the consolidated financial statements included at Item 18 of this annual report). A copy of the form of the CVR agreement is on file with the SEC as Annex B to Amendment No. 2 to the Registration Statement on Form F-4 filed with the Securities and Exchange Commission on March 24, 2011. Pursuant to the CVR agreement, each holder of a CVR is entitled to receive cash payments upon the achievement of certain milestones, if any, based on the achievement of certain cumulative net sales thresholds by Lemtrada ^® (alemtuzumab for treatment of multiple sclerosis). See “Item 10. Additional Information – C. Material Contracts – The Contingent Value Rights Agreement.”

CVR holders are subject to additional risks, including:


▪	the public market for the CVRs may not be active or the CVRs may trade at low volumes, both of which could have an adverse effect on the resale price, if any, of the CVRs;


▪	the market price and trading volume of the CVRs may be volatile;


▪	no payment will be made on the CVRs without the achievement of certain agreed upon milestones. As such, it may be difficult to value the CVRs and accordingly it may be difficult or impossible to resell the CVRs;


▪	if net sales do not exceed the thresholds set forth in the CVR agreement for any reason within the time periods specified therein, no payment will be made under the CVRs and the CVRs will expire without value;


▪	since the US federal income tax treatment of the CVRs is unclear, any part of any CVR payment could be treated as ordinary income and required to be included in income prior to the receipt of the CVR payment;


▪	any payments in respect of the CVRs rank at parity with our other unsecured unsubordinated indebtedness;


▪	we are not prohibited from acquiring the CVRs, whether in open market transactions, private transactions or otherwise and we have already purchased CVRs on several occasions (for more information see “Item 5. Operating and Financial Review and Prospects – Liquidity and Capital Resources – Liquidity.”);


▪	we may, under certain circums tances, purchase and cancel all outstanding CVRs; and

▪

while we have agreed to use diligent efforts (as defined in the CVR agreement), until the CVR agreement is terminated, to achieve each of the remaining Lemtrada ^® related CVR milestones set forth in the CVR agreement, we are not required to take all possible actions to achieve these goals. On July 5, 2016 Sanofi disclosed that, based upon actual sales of Lemtrada ^® in Qualifying Major Markets and in other markets during the respective applicable periods since the Product Launch, Product Sales Milestone #1 had not been met. On February 7, 2018, Sanofi disclosed that, based upon actual sales trends to date, it did not expect that product sales milestones #2, #3 and #4 would be met. Failure to achieve the remaining sales milestones could have an adverse effect on the value of the CVRs (see also Note D.22.c to the consolidated financial statements included at Item 18 of the annual report regarding the settlement of the CVR Trustee Claim pursuant to which, among other things, the CVRs will be delisted from the NASDAQ and extinguished, and the CVR Agreement will be terminated, as was previously disclosed in a Form 6-K filed on October 31, 2019 ).

Item 4. Information on the Company

Introduction

Sanofi is a leading global healthcare company, focused on patient needs and engaged in the research, development, manufacture and marketing of therapeutic solutions.

In the remainder of this section, a product is referred to either by its international non-proprietary name (INN) or its brand name, which is generally exclusive to the company that markets it. In most cases, the brand names of our products, which may vary from country to country, are protected by specific registrations. In this document, products are identified by their brand names used in France and/or in the US.

Sanofi has three principal activities: Pharmaceuticals, Consumer Healthcare (CHC), and Vaccines via Sanofi Pasteur. These activities are operating segments within the meaning of the IFRS 8 accounting standard (see Note D.35. to our consolidated financial statements, included at Item 18 of this annual report).

Our activities include: Immunology, Multiple Sclerosis / Neurology, Oncology, Rare Diseases, Rare Blood Disorders, Cardiovascular, Diabetes, Established Prescription Products ⁽¹⁾ , Consumer Healthcare, and Vaccines. Unlike our Vaccines and Consumer Healthcare activities, which are operating segments within the meaning of IFRS 8, our Immunology, Multiple Sclerosis / Neurology, Oncology, Rare Diseases, Rare Blood Disorders, Cardiovascular, Diabetes and Established Prescription Products activities are franchises whose performance is monitored primarily on the basis of net sales; the products sold by each of those franchises are included in our Pharmaceuticals operating segment. We are also active in emerging markets ⁽²⁾ selling products from our three principal activities; the performance in our emerging markets regions is monitored primarily on the basis of net sales.

For a presentation of the net sales of our activities for the year ended December 31, 2019 , refer to “Item 5 – Results of Operations – Year Ended December 31, 2019 Compared with Year Ended December 31, 2018 ”.

In 2019, we obtained regulatory approval for Libtayo ^® in the EU for the treatment of adults with metastatic or locally advanced cutaneous squamous cell carcinoma (CSCC) who are not candidates for curative surgery or curative radiation.

We also obtained regulatory approvals in the US for Dupixent ^® for adolescent patients aged 12 to 17 years with moderate-to-severe atopic dermatitis, and for the treatment of chronic rhinosinusitis with nasal polyposis (CRSwNP) in adults whose disease is not adequately controlled; in the EU for Dupixent ^® for use in certain adults and adolescents aged 12 years and older as an add-on maintenance treatment for severe asthma with type 2 inflammation, as an add-on therapy with intranasal corticosteroids for the treatment of certain adults with severe chronic rhinosinusitis with n asal polyposis (CRSwNP), and for adolescents aged 12 to 17 years with moderate-to-severe atopic dermatitis; in the EU for Toujeo ^® to include the treatment of diabetes in adolescents and children (aged 6 years and older); and in the US and the EU for Praluent ^® to reduce the risk of cardiovascular events in patients with established cardiovascular disease.

Collaborations are essential to our business and a certain number of our products, whether on the market or under development, are in-licensed products relying on third-party rights or technologies.

A/ History and development of the Company

The current Sanofi corporation was incorporated under the laws of France in 1994 as a société anonyme , a form of limited liability company, for a term of 99 years.

I TEM 4. INFORMATION ON THE COMPANY

B/ Business overview

B.1. Strategy

The market context for Sanofi

A number of fundamental trends continue to point to a positive outlook for the pharmaceutical industry. The global population is growing and aging. Unmet medical needs remain high. The industry has taken steps to increase R&D productivity, with the objective of launching a higher number of innovative medicines. Patients around the world, and a rising middle class in emerging markets, are demanding better care, empowered by access to more information. It is a particularly exciting time scientifically and technologically: the promise of genomics is being realized, immuno-oncology is transforming cancer treatments, and big data is generating new insights into disease. Digital technologies are having a transformative effect across sales, R&D and manufacturing, and acting as enablers for new businesses.

At the same time, increased geopolitical uncertainties, funding challenges, healthcare budget tightening and affordability will continue to put the entire healthcare value chain under significant pricing pressure. Although we believe that pharmaceuticals will remain a fundamentally attractive business within that value chain, the bar for innovation will most likely continue to rise. Payers will continue to put scrutiny on prices and reimbursement, and demand demonstration of real life outcomes. This will be coupled with more innovative pricing and contracting practices. In view of growing concerns over rising health care costs across global markets, the pharmaceutical industry will be increasingly judged by its contribution to improved access for patients and transparent pricing policies.

Strategic framework

At our Capital Markets Day on December 10, 2019, we provided the financial community with details of a new strategic framework to drive innovation and growth, with four key priorities: (1) focus on growth; (2) lead with innovation; (3) accelerate efficiency; and (4) reinvent how we work.

In addition, Sanofi remains committed to Corporate Social Responsibility (CSR). Our CSR strategy relies on high standards of ethics and transparency and is based on improving access to healthcare for underserved patients through dedicated entities like the Sanofi Espoir Foundation and the Department of Global Health; engaging with our communities to create a sustainable ecosystem and engage our employees in supporting young people and future generations, for example by signing up to the French government's PAQTE initiative; and building the environment into our decision-making processes, for example with our "Planet Mobilization" roadmap to measure and limit the environmental impacts of our operations. And in digital, we have created a new standalone role for a Head of Digital, who will be a member of our Executive Committee and will focus equally on internal and external data and on digital strategy and execution.

1) Focus on growth


▪	Dupixent ^® (dupilumab) ⁽¹⁾ - We e xpect to deliver strong growth for Dupixent ^® , driven by its unique mechanism of action - specifically inhibiting overactive signaling of two key proteins (IL-4 and IL-13) - that targets the type 2 inflammation pathway and its favorable safety profile .


▪	Vaccines - Vaccines are expected to deliver growth through differentiated products, market expansion and new launches.


▪	Pipeline - We have identified and prioritized six potentially transformative therapies, with expected submission dates starting in 2021 (see below).

Additional core drivers include treatments in oncology, hematology, rare diseases and neurology, and our strong presence in China.

2) Lead with innovation

Sano fi has recently highlighted six potentially practice-changing therapies in areas of high unmet patient need. These investigational therapies are listed below in order of planned submission timing:


▪	Fitusiran is an RNAi therapeutic in development for the treatment of hemophilia A and B with or without inhibitors, with the potential to be the only therapy to provide consistent efficacy in a monthly subcutaneous dose.


▪	BIVV001 ⁽²⁾ is the first high sustained factor VIII therapy in development with the potential to deliver unprecedented protection for people with hemophilia A, allowing them to achieve near-normal factor activity with a once-weekly dose.

▪

Venglustat is an oral therapy in development for several rare diseases in the category of lysosomal storage disorders (Gaucher type 3 disease, Fabry disease, GM2 gangliosidoses , etc.). Venglustat also shows promise for rare but more common disorders, including (i) autosomal dominant polycystic kidney disease and (ii) some sub-types of Parkinson’s disease suggesting this could be a disease-modifying therapy for GBA-Parkinson’s .


▪	SERD (‘859) is an oral selective estrogen receptor degrader, which aims to be the new standard of care in hormone-receptor-positive breast cancer.


▪	Nirsevimab ⁽³⁾ , a monoclonal antibody , is a potentially cost-effective prevention against respiratory syncytial virus (RSV), with initial focus on protecting infants. Its high affinity to RSV could potentially allow for a single injection to cover the patient for the entire RSV season.


▪	BTKi (‘168) ⁽⁴⁾ is an oral selective BTK inhibitor for multiple sclerosis that has the potential to be the first disease-modifying therapy to also be brain-penetrant.


(1)	In partnership with Regeneron


(2)	In partnership with Swedish Orphan Biovitrum (Sobi)


(3)	In partnership with AstraZeneca


(4)	In partnership with Principia Biopharma




SANOFI / FORM 20-F 2019	15

ITEM 4. INFORMATION ON THE COMPANY

For further details on the development status of these therapies, refer to “B.5. Global research & development” below.

3) Accelerate efficiency

We aim to increase our business operating income (BOI) margin, and have announced efficiency initiatives that we expect will generate €2 billion of savings by 2022. Those savings will fund investments in growth drivers, as well as supporting the increase in our BOI margin.

The efficiency savings are expected to result primarily from (i) limiting spend on de-prioritized businesses, (ii) smart spending initiatives in procurement, and (iii) operational excellence in manufacturing and organizational productivity.

In terms of de-prioritized businesses, we are discontinuing research in diabetes and cardiovascular (DCV) and will not pursue the planned launch of efpeglenatide ⁽¹⁾ . We will also optimize our commercial model for DCV and rheumatoid arthritis, including right-sizing the resources deployed on Praluent ^® (alirocumab) and Kevzara ^® (sarilumab). In conjunction with this, Sanofi and Regeneron announced on December 10, 2019 their intention to restructure their antibody collaboration for Kevzara ^® and Praluent ^® . Additional details can be found at “Item 5. Financial Presentation of Alliances - Alliance Arrangements with Regeneron”.

4) Reinvent how we work

In 2020 , Sanofi will be structured into three core global business units to support our strategy: Specialty Care (immunology, rare diseases, rare blood disorders, neurology/ multiple sclerosis and oncology), Vaccines, and General Medicines (diabetes, cardiovascular, and established products). Each business unit will include the contribution from sales of its products in Emerging Markets including China; the business units will be more fully integrated, and will operate with greater autonomy.

Consumer Healthcare (CHC) will be a standalone business unit, with integrated R&D and manufacturing plus dedicated support functions and information technology. The aim is to enhance the speed and agility of this business and to accelerate digital transformation, all of which are critical if we are to remain competitive in CHC.

Capital allocation policy

We will continue to pursue our focused and disciplined capital allocation policy. Our priorities in deploying the cash generated from our three core GBUs and the future standalone CHC business are, in the following order: (i) organic investment; (ii) business development and merger & acquisition activities, focusing on bolt-on, value-enhancing opportunities to drive scientific and commercial leadership in core therapeutic areas; (iii) growing the annual dividend; and (iv) anti-dilutive share buybacks.

We also have the potential to raise capital through asset disposals, including streamlining “tail” brands in our Established Products business, and by monetizing our stake after the expiry of the lock-up period under the amended and restated investor agreement with Regeneron. See “Item 5. Financial Presentation of Alliances - Alliance Arrangements with Regeneron”.

B.2. Main pharmaceutical products

The sections below provide additional information on our main products. Our intellectual property rights over our pharmaceutical products are material to our operations and are described at “B.7. Patents, Intellectual Property and Other Rights” below. As disclosed in “ 8. Financial Information – A. Consolidated Financial Statements and Other Financial Information – Patents” of this annual report, we are involved in significant litigation concerning the patent protection of a number of these products. For more information on sales performance, see “Item 5. Operating and Financial Review and Prospects – Results of Operations”.

Our Immunology franchise consists of Dupixent ^® (dupilumab) for the treatment of adults and adolescents with moderate-to-severe atopic dermatitis (AD), as add-on maintenance therapy for some patients with moderate to severe asthma and with other medicines to treat chronic rhinosinusitis with nasal polyposis in adults whose disease is not controlled , and Kevzara ^® (sarilumab) for the treatment of adult patients with moderately to severely active rheumatoid arthritis (RA).

Dupixent ^®

Dupixent ^® (dupilumab), a human monoclonal antibody, binds to the interleukin-4 receptor (IL-4R) and has been shown to specifically inhibit overactive signaling of two key proteins (IL-4 and IL-13), which are believed to be major drivers of multiple diseases with underlying type 2 signatures. Type 2 inflammation underlies a number of allergic, atopic, and inflammatory disorders, such as atopic dermatitis (AD) and asthma. Dupixent ^® comes in a pre-filled syringe and can be self-administered as a subcutaneous injection. Dupixent ^® is available in more than 30 countries including the US (since April 2017), several European Union countries (the first launch was in Germany in December 2017) and Japan (since April 2018).

Atopic Dermatitis (AD)

Moderate-to-severe atopic dermatitis, a form of eczema and a chronic inflammatory disease, is characterized by rashes sometimes covering much of the body and can include intense, persistent itching and skin dryness, cracking, redness, crusting and oozing.

Dupixent ^® was granted marketing authorization by the FDA in March 2017 for the treatment of adults with moderate-to-severe AD whose disease is not adequately controlled with topical prescription therapies, or when those therapies are not advisable. In March 2019, the FDA extended the marketing authorization for adolescent patients aged 12 to 17 years. And in January 2020, the FDA accepted for Priority Review the supplemental Biologics License Application (sBLA) for children aged 6 to 11 years; the target action date for the FDA decision is May 26, 2020.

I TEM 4. INFORMATION ON THE COMPANY

The European Commission approved Dupixent ^® in September 2017 for use in adults with moderate-to-severe AD who are candidates for systemic therapy, and extended the marketing authorization in August 2019 to include adolescents aged 12 to 17 years. The European Commission is reviewing an application for an extension to children aged 6 to 11 years.

Long term 76-week data were recently published in the Journal of the American Academy of Dermatology with a safety profile that was consistent with previous clinical trials, and sustained improvement was seen in all efficacy outcomes.

Asthma

Dupixent ^® was granted marketing authorization by the FDA in October 2018 as an add-on maintenance therapy in patients with moderate-to-severe asthma aged 12 years and older with an eosinophilic phenotype or with oral corticosteroid-dependent asthma. In May 2019, the European Commission approved Dupixent ^® for use as an add-on maintenance treatment in patients with severe asthma aged 12 years and older with type 2 inflammation who are inadequately controlled with high dose inhaled corticosteroid plus another medicinal product for maintenance treatment.

Chronic rhinosinusitis with nasal polyposis (CRSwNP)

CRSwNP is a chronic disease of the upper airway that obstructs the sinuses and nasal passages. It can lead to breathing difficulties, nasal congestion and discharge, reduced or loss of sense of smell and taste, and facial pressure. Many patients with CRSwNP have other type 2 inflammatory diseases like asthma, and these patients often have more severe asthma and are often more difficult to treat.

In June 2019, the FDA approved Dupixent ^® for use with other medicines to treat CRSwNP in adults whose disease is not controlled. In October 2019, the European Commission approved Dupixent ^® for use as an add-on therapy with intranasal corticosteroids in adults with CRSwNP for whom therapy with systemic corticosteroids and/or surgery do not provide adequate disease control.

Dupilumab is currently being evaluated in a broad range of clinical development programs for diseases that are driven by Type 2 inflammation, including pediatric atopic dermatitis (age 6 months to 5 years), pediatric asthma, eosinophilic esophagitis, chronic obstructive pulmonary disease, prurigo nodularis, chronic spontaneous urticaria and bullous pemphigoid. See “- B.5. Global Research & Development”.

Dupixent ^® is developed and commercialized in collaboration with Regeneron Pharmaceuticals, Inc. For additional information on the collaboration, see “Item 5. Financial Presentation of Alliances - Alliance Arrangements with Regeneron”.

There are ongoing patent infringement proceedings in several countries initiated by Sanofi and Regeneron against Amgen and Immunex relating to Dupixent ^® . See Note D.22.b) to the consolidated financial statements included at Item 18 of this annual report.

Kevzara ^®

Kevzara ^® (sarilumab) is a human monoclonal antibody that binds to the interleukin-6 receptor (IL-6R) and has been shown to inhibit IL-6R mediated signaling. IL-6 is a cytokine in the body that, in excess and over time, can contribute to the inflammation associated with rheumatoid arthritis. Kevzara ^® is available in 20 countries, including the US.

Rheumatoid arthritis (RA) is a chronic inflammatory autoimmune disease causing inflammation, pain, and eventually joint damage and disability.

In May 2017, the FDA approved Kevzara ^® for the treatment of adult patients with moderately to severely active RA who have had an inadequate response or intolerance to one or more disease modifying anti-rheumatic drugs (DMARDs), such as methotrexate. In June 2017, the European Commission granted marketing authorization for Kevzara ^® in combination with methotrexate for the treatment of moderately to severely active RA in adult patients who have responded inadequately to - or who are intolerant to - one or more DMARDs, such as methotrexate .

Kevzara ^® is developed and commercialized in collaboration with Regeneron Pharmaceuticals, Inc. In December 2019, Sanofi and Regeneron announced their intent to simplify their antibody collaboration for Kevzara ^® and Praluent ^® . For additional information, see “Item 5. Financial Presentation of Alliances - Alliance Arrangements with Regeneron”.

b) Multiple Sclerosis / Neurology

Multiple sclerosis (MS) is an autoimmune disease in which a person’s immune system attacks the central nervous system, damaging myelin, the protective sheath that covers nerve fibers. This causes a break in communication between the brain and the rest of the body, ultimately destroying the nerves themselves, and causing irreversible damage. More than 2.5 million people suffer from MS worldwide.

Our MS franchise consists of Aubagio ^® (teriflunomide), a once-daily, oral immunomodulator, and Lemtrada ^® (alemtuzumab), a monoclonal antibody. Both products treat patients with relapsing forms of MS.

Aubagio ^®

Aubagio ^® (teriflunomide), a small molecule immunomodulatory agent with anti-inflammatory properties, is a once-daily oral therapy.

Aubagio ^® is approved in more than 80 countries around the world including the US (since September 2012) for the treatment of patients with relapsing forms of MS, the EU (since August 2013) for the treatment of adult patients with relapsing remitting MS, and China (since July 2018). Ongoing development efforts include the TeriKIDS study to assess the safety and efficacy of teriflunomide in children (see “B.5. Global research & development”) and global post-marketing registries for pregnancy.

In 2017, Sanofi reached settlement with all 20 generic Aubagio ^® ANDA first filers, granting each a royalty-free license to enter the US market on March 12, 2023.

Lemtrada ^®

Lemtrada ^® (alemtuzumab) is a humanized monoclonal antibody targeting the CD52 antigen. Lemtrada ^® is administered by intravenous infusion as two short courses 12 months apart; for the majority of patients no further treatment is necessary, making Lemtrada ^® the only disease-modifying therapy (DMT) that can provide long term durable efficacy in the absence of continuous dosing.




SANOFI / FORM 20-F 2019	17

ITEM 4. INFORMATION ON THE COMPANY

Lemtrada ^® is approved in more than 70 countries including the EU (since September 2013), and the US (since November 2014). Because of its safety profile, the FDA approved the use of Lemtrada ^® in patients with relapsing forms of MS who have had an inadequate response to two or more drugs indicated for the treatment of MS, and included a black-box warning on potential side effects. In the US, Lemtrada ^® is only available through a restricted distribution program called the Lemtrada ^® Risk Evaluation and Mitigation Strategy (REMS) Program. In January 2020, EMA updated the indication for Lemtrada ^® to include treatment of relapsing-remitting multiple sclerosis if the disease is highly active despite treatment with at least one disease-modifying therapy or if the disease is worsening rapidly. The EMA also added new contraindications for patients with certain heart, circulation or bleeding disorders, and those who have autoimmune disorders other than multiple sclerosis. Alemtuzumab is being evaluated in pediatric patients (see “B.5. Global research & development”).

Bayer Healthcare receives contingent payments based on alemtuzumab global sales revenue. For additional information, see Note D.18. to our consolidated financial statements, included at Item 18 of this annual report.

B.4. Vaccine products

Sanofi Pasteur, the Vaccines division of Sanofi, is a world leader in the vaccine industry and a key supplier of life-saving vaccines all over the world and in publicly funded international markets such as UNICEF, the Pan American Health Organization (PAHO) and the Global Alliance for Vaccines and Immunization (GAVI).

The Sanofi Pasteur portfolio includes the following vaccines:

a) Poliomyelitis, Pertussis and Hib pediatric vaccines

Sanofi Pasteur is one of the key players in pediatric vaccines in both developed and emerging markets, with a broad portfolio of standalone and combination vaccines protecting against up to six diseases in a single injection. Due to the diversity of immunization schedules throughout the world, vaccines vary in composition according to regional specificities.

Tetraxim ^® , a pediatric combination vaccine protecting against diphtheria, tetanus, pertussis and poliomyelitis (polio), was first marketed in 1998. To date, the vaccine has been launched in close to 90 countries outside the US.

Pentaxim ^® , a pediatric combination vaccine protecting against diphtheria, tetanus, pertussis, polio and Hemophilus influenzae type b (Hib), was first marketed in 1997. To date, the vaccine has been launched in more than 100 countries outside the US. In most European, Latin American and Middle Eastern markets, Pentaxim ^® is being gradually replaced by Hexaxim ^® .

Hexaxim ^® / Hexyon ^® / Hexacima ^® is a fully liquid, ready-to-use 6-in-1 (hexavalent) pediatric combination vaccine that provides protection against diphtheria, tetanus, pertussis, polio, Hib and hepatitis B. Hexaxim ^® is the only combination vaccine including acellular pertussis (acP) and inactivated polio vaccines (IPV) currently prequalified by the WHO. Hexaxim ^® is now available in 100 countries outside the US.

Pentacel ^® , a pediatric combination vaccine protecting against diphtheria, tetanus, pertussis, polio and Hib, was launched in the US in 2008.

Shan5 ^® is a 5-in-1 (whole-cell pertussis based) combination vaccine protecting against five diseases (diphtheria, tetanus, pertussis, Hib and hepatitis B). Shan5 ^® is WHO pre-qualified and procured through Unicef to the GAVI countries.

Act’Hib ^® is a standalone vaccine protecting against Hib, and is mainly distributed in the US, Japan and China in conjunction with pertussis combination vaccines that do not contain the Hib valence.

Sanofi Pasteur is a leading provider of polio vaccines and has been a partner of the Global Polio Eradication Initiative (GPEI) for over 30 years, with more than 13 billion doses of oral polio vaccines (OPV) delivered during that time.

Over the 2014-2017 period, Sanofi Pasteur provided 130 million doses of inactivated polio vaccine (IPV) to support the WHO “Polio End Game” strategy for the world's 73 poorest countries, representing 80% of the total IPV volumes used in those countries. On October 1, 2018, the ShanIPV ^® 5-dose vial received WHO pre-qualification.

Vaxelis ^® is a PR5i hexavalent combination vaccine protecting against diphtheria, tetanus, pertussis, polio, Hib and hepatitis B. This vaccine ( developed and distributed in partnership with Merck) was approved in 2016 by the EMA a nd is distributed in various EU countries. Vaxelis ^® was approved by the FDA in December 2018, becoming the first hexavalent vaccine to be approved in the US. Launch is scheduled from 2021 to ensure adequate supply.

b) Influenza vaccines

Sanofi Pasteur is a world leader in the production and marketing of influenza vaccines, offering several distinct influenza vaccines that are sold globally to meet growing demand.

Fluzone ^® Quadrivalent is a quadrivalent inactivated influenza vaccine, produced in the US, containing two type A antigens and two type B antigens in order to provide increased protection against more circulating strains of influenza viruses. Fluzone ^® Quadrivalent/FluQuadri ^® is available in 27 countries (including the US) for children aged over six months, adolescents and adults. Fluzone ^® 0.5ml QIV is the currently-licensed standard dose (15 µg/strain) quadrivalent influenza vaccine for ages 6 months and older.

Fluzone ^® High-Dose vaccine, launched in the US in 2010, was specifically designed to provide greater protection against influenza in people aged 65 and older. It is a trivalent influenza vaccine, including two influenza A strains and one influenza B strain . Fluzone ^® High-Dose is sold in the US, Canada, Australia and the UK. Sanofi Pasteur will continue to deliver and offer this trivalent formulation through the end of the 2019-2020 influenza season. Fluzone ^® High-Dose Quadrivalent for adults aged 65 years of age and older was approved by the FDA in November 2019, and will be available in fall 2020. Compared to Fluzone ^® High-Dose vaccine, it contains an additional influenza B strain and will replace Fluzone ^® High-Dose (which contains three strains). Fluzone ^® High-Dose Quadrivalent is currently also being evaluated by the EMA.

Flublok ^® is a quadrivalent influenza vaccine for adults aged 18 and older. It is the only recombinant protein-based influenza vaccine approved by the FDA. Flublok ^® is currently sold in the US, with global expansion planned over the next several years.

Vaxigrip ^® is licensed in over 150 countries outside the US for people aged six months and older. It is a trivalent influenza vaccine, containing two antigens against type A influenza viruses and one antigen against type B influenza viruses. It is progressively being replaced by Vaxigrip ^® Tetra.

Vaxigrip ^® Tetra is the quadrivalent (QIV) version of Vaxigrip ^® , including two antigens against A strains of influenza viruses and two antigens against B strains. Compared to the trivalent influenza vaccine, it contains an additional influenza B strain . This quadrivalent formulation, VaxigripTetra ^® , was licensed in 2016 and has been launched in more than 40 countries since 2017. VaxigripTetra ^® is not licensed in the US where Fluzone ^® Quadrivalent, which is produced in the US, is sold.

ITEM 4. INFORMATION ON THE COMPANY

c) Adult booster vaccines

Adacel ^® is the first trivalent adolescent and adult booster offering protection against diphtheria, tetanus and pertussis. It also reduces exposure for infants who are not yet immunized, or only partially immunized through maternal immunization. It is available in 40 countries including the US, and otherwise mostly in Europe and Latin America.

Repevax ^® / Adacel ^® -Polio is a combination vaccine that provides protection against diphtheria, tetanus, pertussis and polio. It is currently marketed in 20 countries outside the US, with a strong focus on European markets (France, Germany, UK).

d) Meningitis vaccines

Menactra ^® is the first quadrivalent conjugate vaccine against meningococcal meningitis (serogroups: A, C, Y, and W-135), one of the deadliest forms of meningitis. Menactra ^® is indicated for people aged 9 months through 55 years in the US, Canada, several Middle Eastern countries including Saudi Arabia, and numerous other countries (outside Europe). It is a strong leader in the meningitis quadrivalent market in the US. More than 100 million doses of Menactra ^® have been distributed since launch. It is the only fully liquid (no reconstitution needed) meningitis quadrivalent conjugated vaccine available in the market.

e) Travel and endemic vaccines

Sanofi Pasteur provides a wide range of travel and endemic vaccines including hepatitis A, typhoid, cholera, yellow fever, Japanese encephalitis and dengue, as well as rabies vaccines and immunoglobulins. These products are used in endemic settings in the developing world and are the foundation for important partnerships with governments and organizations such as UNICEF. They are also used by travelers and military personnel in industrialized countries and in endemic areas.

Dengvaxia ^® is available or can be supplied in 12 countries. The Philippines FDA revoked the Dengvaxia ^® license in early 2019. Sanofi filed a motion for reconsideration, which was denied; Sanofi has since filed an appeal before the Office of the President. For more information, please s ee Note D.22.a) to our consolidated financial statements, included at Item 18 of this annual report. In 2018, the European Commission granted marketing authorization for Dengvaxia ^® to prevent dengue disease in individuals aged 9-45 years with a documented prior dengue infection who are living in endemic areas; and in 2019, the FDA approved Dengvaxia ^® to prevent dengue disease caused by serotypes 1-4 of the virus in individuals aged 9-16 years living in endemic areas of the US with a laboratory-documented prior infection.

In most countries where Dengvaxia ^® is approved, the indication is for individuals aged 9 to 45 years or older living in a dengue-endemic area. Based on new results from a supplemental analysis of the long term clinical data on the vaccine reported in November 2017, Sanofi Pasteur has recommended a label update for Dengvaxia ^® to target its use at people with prior dengue infection.

The WHO has recognized the public health value of introducing Dengvaxia ^® in targeted immunization programs, recommending that the vaccine be offered to individuals who have tested positive for prior dengue infection. Current tests detect acute infections and not past infections. We are collaborating with a serotest manufacturer to co-develop an optimized test to be used at the point of care with higher sensitivity (improved ability to detect past infection), while maintaining high specificity (avoid vaccinating truly seronegative persons).

B.5. Global research & development

Since 2018, Sanofi has been engaged in a strong reshaping of its R&D strategy, strengthening the development of innovative products that aim to substantially elevate the standard of care for patients, and prioritizing therapeutic areas where patient need is most urgent: oncology, immunology, rare diseases and multiple sclerosis/neurology. The objective is to develop transformative medicines with the potential to change patients' lives.

R&D is leveraging the investments made a few years ago to establish competency in several therapeutic modalities, and is building robust in-house capability around monoclonal antibodies and antibody-drug conjugate platforms.

The acquisition of Ablynx in 2018 with its specific nanobodies platform, and the recently-announced acquisition of Synthorx with its expanded genetic alphabet platform,have enhanced this position .

In development, sustained efforts are being made to accelerate the pace of delivery for patients, adopting a quick win, fast-fail approach that is underpinned by streamlined governance and pushing decision-making downward with strong team empowerment.

Our aspiration is to build a pipeline of first-in-class or truly differentiated best-in-class medicines, with two-thirds of biologic compounds and two-thirds of the pipeline directly derived from Sanofi internal research.

B.5.1. Pharmaceuticals

B.5.1.1. Organization

Our Global R&D organization is committed to innovation and access, to help patients and communities to achieve better health outcomes, through large-scale preventive care and transformative medicines.

To meet these challenges, Sanofi R&D is fully engaged in a major transformation process, focusing on:


▪	prioritizing and strengthening the portfolio profile with new innovative therapies;


▪	leveraging multiple therapeutic modalities; and


▪	executing to secure accelerated development and quicker access to treatment fo r patients.




24	SANOFI / FORM 20-F 2019

I TEM 4. INFORMATION ON THE COMPANY

Sanofi R&D is organized around five major therapeutic areas (TAs) aligned with our new Global Business Unit (GBU) organization for specialty care:


▪	Oncology


▪	Immunology & Inflammation


▪	Multiple Sclerosis and Neurology


▪	Rare Blood Disorders


▪	Rare D iseases

We recently took the decision to discontinue our research activities in diabetes and cardiovascular (DCV) . The few DCV projects remaining in development are under the responsibility of the General Medicines/Established Products GBU.

These TAs drive a portfolio of R&D projects, ensuring a strategically coherent approach and flawless implementation.

Each TA has its own experts who are responsible for analyzing medical needs, defining project strategy and development plans, and leading the Global Project Teams.

Our R&D Operations handle all operational activities and delivers effective development through integrated, collaborative project teams. Those teams harness high caliber functional expertise and the most appropriate technologies across chemical, biological and pharmaceuticals operations, translational medicine and early development, and clinical sciences.

In Research, a dedicated, integrated platform working across multiple disease areas and methods drives collaboration with internal and external partners to translate human biology research and state-of-the art technologies and processes into novel drug targets and world-class safe and effective drugs.

Sanofi’s R&D operations are concentrated in three major hubs: North America, Germany and France. These hubs help build our scientific intelligence network and facilitate connections and knowledge-sharing between in-house scientists, and with external partners and scientific communities, in order to accelerate our research activities.

B.5.1.2. Governance

Global Project Teams (GPTs) are responsible for developing project strategy and driving the execution of projects through functional sub-teams. GPTs are led by a Global Project Head (GPH) who works in collaboration with a Project Manager (PM), and are built around core functional team members representing each department collaborating in the development project.

Various committees assess product and project development across the R&D value chain, carry out in-depth scientific review, make go and no-go decisions and determine portfolio priorities.

The Research Working Group (RWG) tracks progress on research programs, and endorses entry into preclinical and the path to the First in Human phase (Phase I).

The Benefit-Risk Assessment Committee (BRAC) reviews the preclinical and clinical data before dossier submission.

The Development Working Group (DWG) endorses the path to Proof of Concept (POC), generally before Phase I, and tracks the development of products all along the value chain. This group is also responsible for the portfolio prioritization exercise.

The Integrated Development and Commercialization Council (IDCC) gives prior input to proof of clinical and commercial concept criteria, and endorses go to late development (Phase III start) and go to file.

The clinical portfolio is the result of decisions taken by these committees during their reviews, plus compounds entering the portfolio from the discovery phase or from third parties via acquisition, collaboration or alliances.

As described at “Item 3. Key Information – D. Risk Factors – Risks Relating to Our Business – research and development efforts may not succeed in adequately renewing the product portfolio and – Risks Relating to the Group Structure and Strategy – We may fail to successfully identify external business opportunities or realize the anticipated benefits from our strategic investments”, our product development efforts are subject to the risks and uncertainties inherent in any new product development program.

Phase I studies are the first studies performed in humans, who are mainly healthy volunteers, except for studies in oncology, where Phase I studies are performed in patients. Their main objective is to assess the tolerability, the pharmacokinetic profile (the way the product is distributed and metabolized in the body and the manner by which it is eliminated) and where possible the pharmacodynamic profiles of the new drug (i.e. how the product may react on some receptors).

Phase II studies are early controlled studies in a limited number of patients under closely monitored conditions to show efficacy and short-term safety and to determine the dose and regimen for Phase III studies.

Phase III studies have the primary objective of demonstrating or confirming the therapeutic benefit and the safety of the new drug in the intended indication and population. They are designed to provide an adequate basis for registration.

ITEM 4. INFORMATION ON THE COMPANY

a) Oncology

Products in development

Isatuximab (Sarclisa ^® ) , in-licensed from ImmunoGen, is a monoclonal antibody which selectively binds to CD38, a cell surface antigen expressed in multiple myeloma cancer cells, and other hematological malignancies. Isatuximab kills tumor cells via multiple biological mechanisms including:


▪	anti body-dependent cellular-mediated cytotoxicity (ADCC);


▪	complement-dependent cytotoxicity (CDC);


▪	antibody-dependent cellular phagocytosis (ADCP); and


▪	direct induction of apoptosis (pro-apoptosis) without cross-linking.

Isatuximab also inhibits CD38 ectoenzymatic activity and the expansion of immune-suppressive regulatory T cells and myeloid derived suppressor cells.

The program is currently in registration phase for its lead indication (isatuximab in combination with pomalidomide and dexamethasone in patients with relapsed and refractory multiple myeloma [MM]) based on the Phase III ICARIA-MM study data.

In addition to this Phase III ICARIA-MM trial that is still ongoing, multiple studies in multiple myeloma are under way, and include:


▪	Three pivotal Phase III trials:


–	The Phase III IKEMA trial is a randomized, open label, multicenter study assessing the clinical benefit of isatuximab combined with carfilzomib (Kyprolis ^® ) and dexamethasone versus carfilzomib with dexamethasone in patients with relapsed and/or refractory multiple myeloma previously treated with one to three prior lines.


–	The Phase III IMROZ trial is a randomized, open-label, multicenter study assessing the clinical benefit of isatuximab in combination with bortezomib (Velcade ^® ), lenalidomide (Revlimid ^® ) and dexamethasone versus bortezomib, lenalidomide and dexamethasone in patients with newly diagnosed multiple myeloma not eligible for transplant.


–	The Phase III GMMG HD7 trial is a randomized, open-label, multicenter study assessing the clinical benefit of isatuximab in combination with lenalidomide, bortezomib, and dexamethasone (RVd) for induction and with lenalidomide for maintenance in patients with newly diagnosed multiple myeloma. This study is conducted in collaboration with the German-speaking Myeloma Multicenter Group (GMMG).


▪	Several early phase studies:


–	A Phase I stud y in combination with cyclophosphamide, bortezomib and dexamethasone is ongoing in the treatment of adult patients newly diagnosed with multiple myeloma not eligible for transplant.


–	A Phase I/II study in combination with cemiplimab in the treatment of patients suffering from RRMM.


–	A Phase Ib study evaluating the pharmacokinetics, safety and efficacy of isatuximab (SC and IV) in combination with pomalidomide and dexamethasone in patients with Relapsed/Refractory MM.

In addition, early development studies in solid tumors are ongoing:


▪	a Pha se II study in combination with cemiplimab in the treatment of lymphoma;


▪	a Phase I/II study with isatuximab alone or in combination with atezolizumab in patients with advanced malignancies; and


▪	a Phase II study in combination with atezolizumab in the treatment of solid tumors (metastatic colorectal cancer).

Libtayo ^® - cemiplimab (SAR439684) , a PD-1 inhibitor derived from our alliance with Regeneron, was approved for the treatment of advanced CSCC by the FDA in September 2018 and in the EU in July 2019.

A Phase II program in the treatment of basal cell carcinoma is ongoing.

Additional Phase III studies are also running in different indications:


▪	in the first-line treatment of patients with advanced or metastatic non-small cell lung cancer (NSCLC) whose tumors express PD-L1, as monotherapy and in combination with Platinum-based Doublet Chemotherapy; and


▪	in the treatment of patients with recurrent or metastatic platinum-refractory cervical cancer. In this study, cemiplimab is assessed versus investigator’s choice chemotherapy.

SAR439859 , a selective estrogen receptor degrader (SERD), has begun a Phase I dose expansion study in combination with palbociclib. It has also entered a pivotal Phase II study in second and third line metastatic breast cancer as monotherapy versus physician’s choice of single-agent endocrine therapy. A Phase II 14-day window of opportunity study has been initiated in the prior to surgery/neoadjuvant-like setting to inform further development in the adjuvant setting.

I TEM 4. INFORMATION ON THE COMPANY

SAR408701 is an antibody drug conjugate (ADC) that binds to CEACAM-5, a membrane glycoprotein originally identified as a surface marker on adenocarcinomas of the human gastrointestinal tract. The compound is in Phase III in the treatment of Metastatic Non-Squamous Non-Small Cell Lung Cancer (NSCLC) with CEACAM5 positive tumors. In addition, a study is ongoing to evaluate the activity of the drug in the treatment of NSCLC, colorectal cancer and gastric cancer; a Phase I trial in Japan is also ongoing.

SAR439459 is a monoclonal antibody which inhibits the activity of transforming growth factor beta (TGFß). TGFß regulates several biological processes (including wound healing, embryonic development, and malignant transformation) by controlling many key cellular functions including proliferation, differentiation, survival, migration, and epithelial mesenchyme transition.

ITEM 4. INFORMATION ON THE COMPANY

Enhancements of existing vaccines

Fluzone ^® QIV HD is a higher dose quadrivalent influenza vaccine for the elderly (aged 65 years and older), who do not respond as well to standard-dose influenza vaccines due to aging of the immune system (immuno-senescence). A Phase III study has demonstrated non-inferior immunogenicity and comparable safety to the licensed trivalent Fluzone ^® High-Dose vaccine, which has shown greater protection versus standard dose. In November 2019, the product was approved by the FDA for use in people aged 65 and older, and it will be made available in the US during the 2020-2021 influenza season. Fluzone ^® QIV HD is also being evaluated by the EMA .

Pediatric pentavalent vaccine for the Japanese market: Sanofi Pasteur is developing this vaccine (primary series and booster vaccine) in partnership with Kitasato and Daiichi Sankyo (KDSV) . The vaccine includes diphtheria, tetanus and acellular pertussis (DTaP) from KDSV, and inactivated polio (IPV) and Hib from Sanofi Pasteur.

Shan6 is a cost-effective, all-in-one liquid hexavalent combination vaccine being developed for the Indian market and other low and middle income countries (WHO pre-qualification). It comprises a detoxified whole-cell pertussis component as well as diphtheria toxoid, tetanus toxoid, Hemophilus influenza type b PRP-T, inactivated poliovirus types 1, 2, and 3 and hepatitis B virus components.

SP0173 : The current Adacel ^® (Tdap booster vaccine containing tetanus toxoid, diphtheria toxoid, and 5-component acellular pertussis) is not indicated in the US for persons aged over 64. This development is specifically designed to bridge this indication gap.

MenQuadfi ^TM : Sanofi Pasteur’s Men ACYW-TT vaccine candidate is our latest advance in meningococcal quadrivalent conjugate vaccination, designed to help protect an expanded patient group including infants and adolescents through older adults. Phase II and initial Phase III trials have been performed in the US and the EU. Additional Phase III trials are ongoing in the EU, Asia and Latin America. The safety and immunogenicity profiles of the vaccine candidate are encouraging . In June 2019, the FDA accepted for review a biologic licence application for MenQuadfi ^TM , for use in people aged 2 years and older; in October 2019, an application was submitted in the EU for use in people aged 12 months and older. Phase III trials are ongoing to evaluate immunogenicity and safety in infants aged 6 weeks and older.

VerorabVax ^® (VRVg) is a next-generation purified human rabies vaccine under development, aimed at replacing both of Sanofi Pasteur’s currently commercialized rabies vaccines (Imovax ^® Rabies and Verorab ^® ). It will be cultured on Vero cells without animal or human material.

New vaccine targets

Nirsevimab is a monoclonal antibody which has been engineered to have a long half-life, so that only one dose would be needed for the entire Respiratory Syncytial Virus (RSV) season to provide passive immunity and prevent RSV infection in all infants for their first RSV season (and in high-risk infants for their first and second RSV seasons). Sanofi Pasteur has an agreement with MedImmune/AstraZeneca to develop and commercialize nirsevimab. Positive primary analysis of the Phase IIb trial has demonstrated the safety and efficacy of nirsevimab . The Phase III study started in 2019 . The product received fast-track designation from the FDA in 2015 and received FDA Breakthrough Therapy designation in February 2019 . The EMA granted PRIME eligibility to nirsevimab in February 2019 .

RSV infant vaccine : Sanofi Pasteur has a Cooperative Research and Development Agreement (CRADA) with the US National Institutes of Health (NIH) to develop a live attenuated RSV vaccine for immunization in infants aged 4 months and older. The lead candidate(s) are currently under Phase I evaluation in healthy infants without previous RSV exposure.

Pneumo Conjugate Vaccine (PCV) : Sanofi Pasteur is developing with SK chemicals (South Korea) a pneumococcal conjugate vaccine with broader coverage. This vaccine entered Phase I in December 2018.

Herpes Simplex Virus (HSV) type 2 is a member of the herpes virus family and as such establishes life-long infections - mainly genital herpes - with latent virus established in neural ganglia. Although antivirals currently exist to treat these infections, no vaccine exists. Our vaccine candidate is a live attenuated virus and is being assessed as a therapeutic vaccine to reduce recurrence and transmission. It is currently in Phase I. In 2014, Sanofi Pasteur signed a contract with Immune Design Corp. to collaborate on the development of this therapeutic herpes simplex virus vaccine candidate by exploring the potential of various combinations of agents.

The Vero Yellow Fever (vYF) vaccine candidate is a next generation freeze-dried live attenuated yellow fever vaccine produced on Vero cell line, for subcutaneous and intra-muscular administrations in populations over 9 months of age. This next generation vaccine aims at replacing both Stamaril and YF-VAX with a single product, securing a sustainable and consistent supply available worldwide. In January 2020, the first Phase I/II trial was initiated in the US.

B.5.3. R&D expenditures for late stage development

Expenditures on research and development amounted to € 6,022 million in 2019 , comprising € 4,622 million in the Pharmaceuticals segment; € 148 million in the Consumer Healthcare segment; € 653 million in the Vaccines segment; and € 599 million allocated to “Other”, representing the R&D support function. Research and development expenditures were the equivalent of about 16.7 % of net sales in 2019 , compared to about 17.1 % in 2018 and about 15.6 % in 2017 .

The increase in R&D expenditures in 2019 is mainly due to a greater proportion of products being in late stage development. It is also due to the Vaccines segment with an increase of 17.7% in 2019. Preclinical research in the Pharmaceuticals segment amounted to €825 million in 2019, compared to €983 million in 2018 and €1,086 million in 2017. Of the remaining €3,797 million relating to clinical development in the Pharmaceuticals segment (€3, 589 million in 2018 and €3 , 032 million in 2017), the largest portion covers Phase III or post-marketing studies, reflecting the cost of monitoring large scale clinical trials.

I TEM 4. INFORMATION ON THE COMPANY

B.6.1. Marketing and distribution

We have a commercial presence in approximately 100 countries, and our products are available in more than 170 countries. A breakdown of our aggregate net sales by geographical region is presented in “Item 5. Operating and Financial Review and Prospects – Results of Operations – Year Ended December 31, 2019 Compared with Year Ended December 31, 2018 .” Sanofi is the eighth largest pharmaceutical company globally by sales. Our main markets in terms of net sales are respectively:


▪	Emerging Markets (see definition in “– Information on the Company – Introduction” above): Sanofi is the leading healthcare company in emerging markets, and the seventh largest pharmaceutical company in China.


▪	The US: we rank twelfth with a market share of 3.3%.


▪	Europe: we are the second largest pharmaceutical company in France where our market share is 5.6% and we rank sixth in Germany with a 3.5% market share.


▪	Other countries: our market share in Japan is 1.7%.

Although specific distribution patterns vary by country, we sell prescription drugs primarily to wholesale drug distributors, independent and chain retail drug outlets, hospitals, clinics, managed-care organizations and government institutions. Rare disease products are also sold directly to physicians. With the exception of Consumer Healthcare products, our drugs are ordinarily dispensed to patients by pharmacies upon presentation of a doctor’s prescription. Our Consumer Healthcare products are also sold and distributed through e-commerce, which is a growing trend in consumer behavior. Our vaccines are sold and distributed through multiple channels including physicians, pharmacies, hospitals, private companies and distributors in the private sector, and governmental entities and non-governmental organizations in the public and international donor markets.

We use a range of channels from in-person to digital to disseminate information about and promote our products among healthcare professionals, ensuring that the channels not only cover our latest therapeutic advances but also our established prescription products, which satisfy patient needs in some therapy areas. We regularly exhibit at major medical congresses. In some countries, products are also marketed directly to patients by way of television, radio, newspapers and magazines, and digital channels (such as the internet). National education and prevention campaigns can be used to improve patients’ knowledge of their conditions.

Our sales representatives, who work closely with healthcare professionals, use their expertise to promote and provide information on our drugs. They represent our values on a day-to-day basis and are required to adhere to a code of ethics and to internal policies in which they receive training.

Although we market most of our products through our own sales forces, we have entered into and continue to form partnerships to co-promote/co-market certain products in specific geographical areas. Our major alliances are detailed at “Item 5. Operating and Financial Review and Prospects – Financial Presentation of Alliances.” See also “Item 3. Key Information – D. Risk Factors – We rely on third parties for the discovery, manufacture and marketing of some of our products.”

B.6.2. Competition

The pharmaceutical industry continues to experience significant changes in its competitive environment.

There are four types of competition in the prescription pharmaceutical market:


▪	com petition between pharmaceutical companies to research and develop new patented products or address unmet medical needs;


▪	competition between different patented pharmaceutical products marketed for the same therapeutic indication;


▪	competition between original and generic products or between original biological products and biosimilars, at the end of regulatory exclusivity or patent protection; and


▪	comp etition between generic or biosimilar products.

Generics manufacturers who have received all necessary regulatory approvals for a product may decide to launch a generic version before the patent expiry date, even in cases where the owner of the original product has already commenced patent infringement litigation against the generics manufacturer. Such launches are said to be “at risk” for the promoter of the generic product because it may be required to pay damages to the owner of the original product in the context of patent infringement litigation; however, such launches may also significantly impair the profitability of the pharmaceutical company whose product is challenged.

Drug manufacturers also face competition through parallel trading, also known as reimportation. This takes place when drugs sold abroad under the same brand name as in a domestic market are imported into that domestic market by parallel traders, who may repackage or resize the original product or sell it through alternative channels such as mail order or the internet. This situation is of particular relevance to the EU, where such practices have been encouraged by the current regulatory framework. Parallel traders take advantage of the price differentials between markets arising from factors including sales costs, market conditions (such as intermediate trading stages), tax rates, or national regulation of prices.

Finally, pharmaceutical companies face illegal competition from falsified drugs. The WHO estimates that falsified products account for 10% of the market worldwide, rising to 30% in some countries. All therapeutic areas are affected, also including vaccines. However, in markets where powerful regulatory controls are in place, falsified drugs are estimated to represent less than 1% of market value.

The same types of competition apply in Consumer Healthcare, except that in this business there are two types of generic products: private labels and store brands.




SANOFI / FORM 20-F 2019	33

ITEM 4. INFORMATION ON THE COMPANY

In Vaccines, there are two types of competition:


▪	competition between vaccine companies to research and develop new patented products or address unmet medical needs; and


▪	competition between different patented (or non-patented) vaccine products marketed for the same therapeutic indication;

Generics and biosimilars are not an issue in vaccines at present, since vaccines are still mostly produced from proprietary viral or bacterial strains. As with pharmaceutical drugs, vaccine manufacturers can face competition through parallel trading. However, the extent of such practices is limited by the need for cold chain distribution of vaccines, and by the fact that vaccines are sold and administered through pharmacies or dispensing physicians.

B.6.3. Regulatory framework

The pharmaceutical and health-related biotechnology sectors are highly regulated. National and supranational health authorities administer a vast array of legal and regulatory requirements that dictate pre-approval testing and quality standards to maximize the safety and efficacy of a new medical product. These authorities also regulate product labeling, manufacturing, importation/exportation and marketing, as well as mandatory post-approval commitments that may include pediatric development.

The submission of an application to a regulatory authority does not guarantee that a license to market will be granted. Furthermore, each regulatory authority may impose its own requirements during the course of the product development and application review. It may refuse to grant approval and require additional data before granting approval, even though the same product has already been approved in other countries. Regulatory authorities also have the authority to request product recalls and product withdrawals, and to impose penalties for violations of regulations based on data that are made available to them.

Product review and approval can vary from six months or less to several years from the date of application depending upon the country. Factors such as the quality of data, the degree of control exercised by the regulatory authority, the review procedures, the nature of the product and the condition to be treated, play a major role in the length of time a product is under review.

In the EU , there are three main procedures for applying for marketing authorization:

▪

The centra lized procedure is mandatory for drugs derived from biotechnologies; new active substances designed for human use to treat HIV, viral diseases, cancer, neurodegenerative diseases, diabetes and auto-immune diseases; orphan drugs; and innovative products for veterinary use. When an application is submitted to the EMA, the scientific evaluation of the application is carried out by the Committee for Medicinal Products for Human Use (CHMP) and a scientific opinion is prepared. This opinion is sent to the European Commission which adopts the final decision and grants an EU marketing authorization. Such a marketing authorization is valid throughout the EU and the drug may be marketed within all EU Member States.

▪

If a company is seeking a national marketing authorization in more than one Member State, two procedures are available to facilitate the granting of harmonized national authorizations across Member States: the mutual recognition procedure or the decentralized procedure. Both procedures are based on the recognition by national competent authorities of a first assessment performed by the regulatory authority of one Member State.


▪	National au thorizations are still possible but are only for products intended for commercialization in a single EU Member State or for line extensions to existing national product licenses.

In the EU, vaccines are treated as pharmaceutical products, and therefore have to obtain marketing authorization under the centralized procedures described above.

Generic products are subject to the same marketing authorization procedures. A generic product must contain the same active medicinal substance as a reference product approved in the EU. Generic applications are abridged: generic manufacturers only need to submit quality data and demonstrate that the generic drug is “bioequivalent” to the originator product (i.e. performs in the same manner in the patient’s body), but do not need to submit safety or efficacy data since regulatory authorities can refer to the reference product’s dossier.

Another relevant aspect in the EU regulatory framework is the “sunset clause” under which any marketing authorization ceases to be valid if it is not followed by marketing within three years, or if marketing is interrupted for a period of three consecutive years.

In the US , applications for pharmaceutical approval and biological product licensure are submitted for review to the FDA, which has broad regulatory powers over all pharmaceutical and biological products that are intended for sale and marketing in the US. To commercialize a product in the US, a new drug application (NDA) under the Food, Drug and Cosmetic (FD&C) Act, or a Biological License Application (BLA) under the Public Health Service (PHS) Act, must be submitted to the FDA for filing and pre-market review. Specifically, the FDA must decide whether the product is safe and effective for its proposed use; if the benefits of the drug’s use outweigh its risks; whether the drug’s labeling is adequate; and if the manufacturing of the drug and the controls used for maintaining quality are adequate to preserve the drug’s identity, strength, quality and purity. Based upon this review, the FDA can stipulate post-approval commitments and requirements. Approval for a new indication of a previously approved product requires submission of a supplemental NDA (sNDA) for a drug or a supplemental BLA (sBLA) for a biological product.

Sponsors wishing to market a generic drug can file an Abbreviated NDA (ANDA) under 505(j) of the FD&C Act. These applications are “abbreviated” because they are generally not required to include data to establish safety and effectiveness but need only demonstrate that their product is bioequivalent (i.e. performs in humans in the same manner as the originator’s product) to a reference product. Consequently, the length of time and cost required for development of generics can be considerably less than for the innovator’s drug. The ANDA pathway in the US can only be used for generics of drugs that can be referenced as having been approved under the FD&C Act.

I TEM 4. INFORMATION ON THE COMPANY

The FD&C Act provides another abbreviated option for NDA approved products, which is a hybrid between an NDA and ANDA called the 505(b)(2) pathway. This 505(b)(2) pathway enables a sponsor to rely on the FDA’s findings that the reference product is safe and effective, based on the innovator’s preclinical and clinical data. Similarly, under the PHS act, there exists an abbreviated licensure pathway for biological products shown to be biosimilar (highly similar with no clinically meaningful differences) or interchangeable with an FDA-licensed reference BLA product

In Japan , the entire process of approval review from review-related inspections and clinical trial consultation to review for the drugs approved by the Ministry of Health, Labour and Welfare (MHLW) is undertaken by the Pharmaceuticals and Medical Devices Agency (PMDA). The PMDA conducts first scientific review of the NDA submitted, assessing particularly the safety, efficacy and quality of the product or medical device proposed. Results of this primary evaluation are then submitted to the PMDA’s external experts. After a second evaluation based on the external experts’ feedback, a report is provided; the Pharmaceutical Affairs and Foods Sanitation Council (PAFCS) - one of the councils organized under the J-MHLW as advisory commission - is consulted, and advises the MHLW on final approvability.

For Japanese registrations, clinical data for Japanese patients are necessary. The regulatory authorities can require local clinical studies, though they also accept multi-regional studies including Japan. In some cases, bridging studies have been conducted to verify extrapolability of foreign clinical data to Japanese patients and to obtain data to determine the appropriateness of the dosages for Japanese patients.

The MHLW may require additional post-approval studies (Phase IV) for some specific cases, to further evaluate safety and/or to gather information on the use of the product under specified conditions. In approval of new drugs, new indications, new dosages or new administrations, reexamination period is determined by the MHLW. Post-marketing information on a drug for the predetermined period after approval is collected to reconfirm its efficacy, safety and quality at the end of the period. In this collection, post-marketing surveillance (PMS) which is non-interventional study and post-marketing clinical trial are involved.

To promote the development of innovative drugs and bring them into early practical use in Japan ahead of the world, the Sakigake (a Japanese term meaning “forerunner”) review designation program was introduced in April 2015. The PMDA reviews designated products on a priority basis with the aim of reducing their review time from the normal 12 months to six months through rolling review. Based on the National Health Insurance (NHI) price system, the “Premium” classification in term of price is restricted to new products from companies which conduct R&D on “pharmaceuticals truly conducive to the improvement of healthcare quality,” i.e. (i) pediatric/orphan drugs and (ii) drugs to treat diseases that cannot be adequately controlled with existing drugs.

For generic products, the data necessary for filing are similar to EU and US requirements. Companies only need to submit quality data, and data demonstrating bioequivalence to the originator product, unless the drug is biopharmaceutical. Common Technical Document (CTD) submission for generics has been mandatory since March 2017.

The International Council for Harmonization of Technical Requirements for Pharmaceuticals for Human Use (ICH) was created in 1990 and reformed in 2015.

ICH includes today 16 Members and 32 Observers. Harmonization is achieved through the development of ICH Guidelines via a process of scientific consensus with regulatory and industry experts working side-by-side.

In addition to the joint efforts, Free Trade Agreements (FTAs) have proven to be one of the best ways to open up foreign markets to exporters and to allow for discussions on harmonization topics for regulatory authorities. Some agreements, such as the Agreement on Trade Related Aspects of Intellectual Property Rights (TRIPS), are international in nature, while others are between specific countries. The requirements of many countries (including Japan and several EU Member States) to negotiate selling prices or reimbursement rates for pharmaceutical products with government regulators significantly extend the time to market entry beyond the initial marketing approval. While marketing authorizations for new pharmaceutical products in the EU have been largely centralized within the European Commission in collaboration with the EMA, pricing and reimbursement remain a matter of national competence.

B.6.4. Pricing & Reimbursement

Increasingly, efforts to control drug expenditures in most markets in which Sanofi operates influence the pricing and access of pharmaceuticals. The nature of those controls varies from country to country, but some common themes include reference pricing, systematic price reductions, formularies, volume limitations, patient co-pay requirements, and generic substitution. In addition, governments and third-party payers are increasingly demanding comparative and/or relative effectiveness data and budget impact modelling to support their decision-making process. They are also increasing their use of emerging healthcare information technologies, such as electronic prescribing and health records, to increase oversight on efficacy and safety and to improve compliance with prescribing guidelines. As a result, the environment in which pharmaceutical companies must operate in order to make their products available to patients and providers who need them becomes more complex each year.

While the political ambition to expand healthcare coverage has become a noticeable feature in many regions and provides opportunities for the industry, it also puts pressure on budgets and brings with it a wave of price and volume control measures. Many countries and regions have increased pressure on pricing through joint procurement and negotiation. National production, whether through a policy of industrialization, technology transfer agreements or preferential conditions for local production, is also a growing issue.

US Payer Structure

Private health insurance is offered widely as part of employee benefit packages, and is the main source of access to subsidized healthcare provision. Some individuals purchase private health plans directly, while publicly-subsidized programs provide cover for retirees, the poor, the disabled, uninsured children, and serving or retired military personnel. Double coverage can occur.

Private (commercial) health insurance includes:


▪	Managed C are Organizations (MCOs) combine the functions of health insurance, delivery of care, and administration. MCOs use specific provider networks and specific services and products. There are three types of managed care plans: Health Maintenance Organizations (HMOs), Preferred Provider Organizations (PPOs), and Point of Service (POS) plans.




SANOFI / FORM 20-F 2019	35

ITEM 4. INFORMATION ON THE COMPANY


▪	Pharmacy b enefit managers (PBMs) serve as intermediaries between insurance companies, pharmacies and manufacturers to negotiate rebates and discounts on formulary placement for commercial health plans, self-insured employer plans, Medicare Part D plans, and federal and state government employee plans.

Public health insurance includes:

▪

Medic are, which provides health insurance for retirees and for people with permanent disabilities. The basic Medicare scheme (Part A) provides hospital insurance only, and the vast majority of retirees purchase additional cover through some or all of three other plans named Part B, Part C and Part D. Part D enables Medicare beneficiaries to obtain outpatient drug coverage. Almost two-thirds of all Medicare beneficiaries have enrolled in Part D plans.


▪	Medic aid, which provides health insurance for low-income families, certain qualified pregnant women and children, individuals receiving supplemental security income, and other eligible persons determined on a state-by-state basis.

The US market has seen increased consolidation of key payer organizations. Most notably, the CVS-Aetna and Cigna-ESI mergers point to a strong role for integrated payers and PBMs in terms of product access and affordability. This trend may also impact market pricing for pharmaceuticals going forward. With the largest three PBMs now covering over 75% of the market, consolidation has led to significant negotiating power for commercial and Medicare Part D plans. Commercial payers continue to employ tools designed to lower plan-level net costs; these include formulary management tools and exclusions, benefit design changes and generic conversions, the adoption of biosimilars (which are now beginning to transform the US biologics landscape), and other methods that generally shift more costs to patients, even when plan costs are flat or declining.

The current Administration continues to focus on lowering the cost of prescription drugs, including policies to address the disparity between drug prices paid by Americans and the rest of the world (the International Pricing Index (IPI) and importation plans). The IPI, as initially proposed, would essentially tether domestic prices for certain Part B drugs to the international markets. It is possible that a revised IPI proposal may include a broader set of Part B drugs as well as Part D drugs. Likewise, the Administration and some states are considering implementing prescription drug importation policies. However, these too are not finalized and several implementation questions remain.

The US Congress also continues to focus on prescription drug pricing, with the US Senate taking a more bipartisan approach. The US House has to date opted for a partisan approach that would likely have a chilling effect on US jobs and innovation from the biopharmaceutical industry. Based on public statements, the House-passed drug pricing legislation (H.R. 3) is unlikely to become law in 2020 given public opposition from Senate Republican leadership.

Until policies are enacted to lower out-of-pocket costs for patients, these issues will continue to receive significant attention and focus from Democrats and Republicans at the state and federal levels.

Significant trends in China:

In 2019, China continued to pursue its objective of reforming its healthcare system, so as to ensure access to high quality drugs and bring innovative medicines to the country. Following major updates to the National Reimbursement Drug List (NRDL) in 2017 and 2018, negotiations during 2019 led to a further 119 drugs being added. Of these, 52 were Western medicines, including Sanofi’s Aubagio ^® and Lyxumia ^® . A further 31 medicines were subject to price re-negotiations, 27 of them successfully (including Renvela ^® ), although success came at the cost of substantial price cuts. Until a product is included in the NRDL it can expect only limited access to the Chinese market. Drugs listed on the NRDL are distributed mainly through public health insurance schemes.

Substantial price cuts were also obtained from the national rollout of a centralized procurement scheme, based on the April 2019 pilot ‘4+7’ tender scheme (4 municipalities and 7 major cities participated). The pilot ‘4+7’ scheme had a winner-takes-all format. The new tender allowed up to three suppliers. There have been further announcements that the list of products to come under centralized procurement will be expanded from the 25 originally chosen for the pilot (which included Plavix ^® and Aprovel ^® ). At the beginning of 2020, a further 33 drugs were added to the list, including Amaryl ^® , for implementation during 2020 .

With the backlog of regulatory approvals essentially cleared, a VAT reduction (to 3%) for selected orphan drugs, and the introduction of a priority review pathway by the National Medical Products Administration among other measures, access to the Chinese market is growing. However, many questions still remain including (significantly) a policy for orphan drugs funding, which is expected in 2020.

Significant trends in other markets:

In Canada, the overhaul of the PMPRB price monitoring rules and procedures is finally expected to be implemented on July 1, 2020. This will include measures such as increasing the number of countries used for price benchmarking. An Advisory Council Report, published in June 2019, recommended a single, universal public system for the administration of prescription drugs. One of the recommendations – the establishment of a Canadian Drug Agency, which would eventually be responsible for the evaluation of drug effectiveness, prescription drug price negotiations and the creation of a national formulary (pilot version expected in 2022) – has been allowed for in the 2019/2020 budget.

In South America, inflation continues to disrupt several economies. Argentina, with over 50% inflation recorded in 2019, is now experiencing shortages and funding difficulties, with many pharmaceutical companies adjusting medicine prices in line with inflation. The newly elected government reached a deal with industry to cut prices by 8% and impose a short-term price freeze as a remedial measure. Long term sustainability will, however, rely on an overhaul of the economic situation

We believe that third-party payers will continue to act to curb the cost of pharmaceutical products. While the impact of those measures cannot be predicted with certainty, we are taking the necessary steps to defend the accessibility and price of our products in order to reflect the value of our innovative product offerings, and we continue to develop and pilot innovative contracting platforms with commercial payers to better align our price and value across multiple therapeutic areas including diabetes, rheumatoid arthritis, multiple sclerosis and asthma.

B.7. Patents, intellectual property and other rights

B.7.1. Patents


▪	Patent protection

We own a broad portfolio of patents, patent applications and patent licenses worldwide. These patents are of various types and may cover: active ingredients; pharmaceutical formulations; product manufacturing processes; intermediate chemical compounds; therapeutic indications/methods of use; delivery systems; and enabling technologies, such as assays.

Patent protection for individual products typically extends for 20 years from the patent filing date in countries where we seek patent protection. A substantial part of the 20-year life span of a patent on a new molecule (small molecule or biologic) has generally already passed by the time the related product obtains marketing authorization. As a result, the effective period of patent protection for an approved product’s active ingredient is significantly shorter than 20 years. In some cases, the period of effective protection may be extended by procedures established to compensate regulatory delay in Europe (via Supplementary Protection Certificate or SPC), in the US (via Patent Term Extension or PTE) and in Japan (also via PTE).

Additionally, the product may benefit from the protection of patents obtained during development or after the product’s initial marketing authorization. The protection a patent provides to the related product depends upon the type of patent and its scope of coverage and may also vary from country to country. In Europe for instance, applications for new patents may be submitted to the European Patent Office (EPO), an intergovernmental organization which centralizes filing and prosecution. As of December 2017, an EPO patent application may cover the 38 European Patent Convention Member States, including all Member States of the EU. The granted “European Patent” establishes corresponding national patents with uniform patent claims among the Member States. Additionally, a number of patents prosecuted through the EPO may pre-date the European Patent Convention accession of some current European Patent Convention Member States, resulting in different treatment in those countries.

In 2013, EU legislation was adopted to create a European Unitary Patent and a Unified Patent Court. However, it will only enter into force once the agreement on the Unified Patent Court is ratified by at least 13 Member States. As of the date of this document, 16 countries including France have ratified the agreement, but ratification by Germany is still outstanding, and the process is impacted by Brexit.

The Unitary Patent will provide unitary protection within the participating states of the EU (when ratified by the Member States with the exception of Croatia, Spain, and Poland, not currently signatories to the agreement). The Unified Patent Court will be a specialized patent court with exclusive jurisdiction for litigation relating to European patents and Unitary Patents. The Court will be composed of a central division (headquartered in Paris) and several local and regional divisions in the signatory Member States to the agreement. The Court of Appeal will be located in Luxembourg.

We monitor our competitors and vigorously seek to challenge patent infringements when such infringements would negatively impact our business objectives. See “Item 8 - A. Consolidated Financial Statements and Other Financial Information - Information on Legal or Arbitration Proceedings - Patents” of this annual report.

The expiration or loss of a patent covering a new molecule, typically referred to as a compound patent, may result in significant competition from generic products and can result in a dramatic reduction in sales of the original branded product (see “Item 3. Key Information - D. Risk Factors”). In some cases, it is possible to continue to benefit from a commercial advantage through product manufacturing trade secrets or other types of patents, such as patents on processes, intermediates, compound structure, formulations, methods of treatment, indications or delivery systems. Certain categories of products, such as traditional vaccines and insulin, were historically relatively less reliant on patent protection and may in many cases have no patent coverage. It is nowadays increasingly frequent for novel vaccines and insulins also to be patent protected. Finally, patent protection is of comparatively lesser importance to our Consumer Healthcare and generics businesses, which rely principally on trademark protection.


▪	Regulatory exclusivity

In some markets, including the EU and the US, many of our pharmaceutical products may also benefit from multi-year regulatory exclusivity periods, during which a generic or biosimilar competitor may not rely on our clinical trial and safety data in its drug application. Exclusivity is meant to encourage investment in research and development by providing innovators with exclusive use, for a limited time, of the innovation represented by a newly approved drug product. This exclusivity operates independently of patent protection and may protect the product from generic competition even if there is no patent covering the product.

In the US, the FDA will not grant final marketing authorization to a generic competitor for a New Chemical Entity (NCE) until the expiration of the regulatory exclusivity period (five years) that commences upon the first marketing authorization of the reference product. The FDA will accept the filing of an Abbreviated New Drug Application (ANDA) containing a patent challenge one year before the end of this regulatory exclusivity period. In addition to the regulatory exclusivity granted to NCEs, significant line extensions of existing NCEs may qualify for an additional three years of regulatory exclusivity if certain conditions are met. In the US, a different regulatory exclusivity period applies to biological drugs. The Biologics Price Competition and Innovation Act of 2009 (“BPCIA”) was enacted on March 23, 2010 as part of the Affordable Care Act. The BPCIA provides that an application for a biosimilar product that relies on a reference product may not be submitted to the FDA until four years after the date on which the reference product was first licensed, and that the FDA may not approve a biosimilar application until 12 years after the date on which the reference product was first licensed. US Federal and state officials, including the current Administration, are continuing to focus on the cost of health coverage and health care although the future policy, including the nature and timing of any changes to the Affordable Care Act, remains unclear.

In the EU, regulatory exclusivity is available in two forms: data exclusivity and marketing exclusivity. Generic drug applications will not be accepted for review until eight years after the first marketing authorization (data exclusivity). This eight-year period is followed by a two-year period during which generics cannot be marketed (marketing exclusivity). The marketing exclusivity period can be extended to three years if, during the first eight-year period, the marketing authorization holder obtains an authorization for one or more new therapeutic indications which are deemed to provide a significant clinical benefit over existing therapies. This is known as the “8+2+1” rule.




SANOFI / FORM 20-F 2019	37

ITEM 4. INFORMATION ON THE COMPANY

In Japan, the regulatory exclusivity period varies: four years for medicinal products with new indications, formulations, dosages, or compositions with related prescriptions; six years for new drugs containing a medicinal composition or requiring a new route of administration; eight years for drugs containing a new chemical entity; and ten years for orphan drugs or new drugs requiring pharmaco-epidemiological study.


▪	Emerging markets

One of the main limitations on our operations in emerging market countries is the lack of effective intellectual property protection or enforcement for our products. Additionally, these same countries frequently do not provide non-patent exclusivity for innovative products. While the situation has gradually improved, the lack of protection for intellectual property rights or the lack of robust enforcement poses difficulties in certain countries. Additionally, in recent years a number of countries facing health crises have waived or threatened to waive intellectual property protection for specific products, for example through compulsory licensing of generics. See “Item 3. Key Information - D. Risk Factors - Risks Relating to Sanofi’s Structure and Strategy - The globalization of our business exposes us to increased risks in specific areas”.


▪	Pediatric extension

In the US and the EU, under certain conditions, it is possible to extend a product’s regulatory exclusivity for an additional period of time by providing data on pediatric studies.

In the US, the FDA has invited us by written request to provide additional pediatric data on several of our main products. Under the Hatch-Waxman Act, timely provision of data meeting the FDA’s requirements may result in the FDA extending regulatory exclusivity and patent life by six months, to the extent these protections have not already expired (the so-called “pediatric exclusivity”).

In Europe, a regulation on pediatric medicines provides for pediatric research obligations with potential associated rewards including extension of patent protection (for patented medicinal products) and six - month regulatory exclusivity for pediatric marketing authorization (for off-patent medicinal products).

In Japan, there is no pediatric research extension of patent protection for patented medicinal products. However, regulatory exclusivity may be extended from eight to ten years.


▪	Orphan drug exclusivity

Orphan drug exclusivity may be granted in the US to drugs intended to treat rare diseases or conditions (those affecting fewer than 200,000 patients in the US, or in some cases more than 200,000 with no expectation of recovering costs).

Obtaining orphan drug exclusivity is a two - step process. An applicant must first seek and obtain orphan drug designation from the FDA for its drug for one or more indications. If the FDA approves a drug for the designated indication, the drug will generally receive orphan drug exclusivity for such designated indication.

The FDA may approve applications for the “same” drug for indications not protected by orphan exclusivity.

Orphan drug exclusivities also exist in the EU and Japan.


▪	Product overview

We summarize below the intellectual property coverage (in some cases through licenses) of our most significant marketed products in terms of sales, in our major markets. In the discussion of patents below, we focus on active ingredient patents (compound patents) and, in the case of NCEs , on any later filed patents listed as applicable in the FDA’s list of Approved Drug Products with Therapeutic Equivalence Evaluations (the “Orange Book”) or in its foreign equivalents. For biologics , the Orange Book listing does not apply.

These patents or their foreign equivalents tend to be the most relevant in the event of an application by a competitor to produce a generic or a biosimilar version of one of our products (see “- Challenges to Patented Products” below). In some cases, products may also benefit from pending patent applications or from patents not eligible for Orange Book listing (in the case of NCEs, e.g. patents claiming industrial processes). In each case below, we specify whether the active ingredient is claimed by an unexpired patent. Where patent terms have been extended to compensate for US Patent and Trademark Office (USPTO) delays in patent prosecution (Patent Term Adjustment - PTA) or for other regulatory delays, the extended dates are indicated below. The US patent expirations presented below reflect USPTO dates, and also reflect six - month pediatric extensions when applicable. Where patent terms have expired we indicate such information and mention whether generics are on the market.

We do not provide later filed patent information relating to formulations already available as an unlicensed generic. References below to patent protection in Europe indicate the existence of relevant patents in most major markets in the EU. Specific situations may vary by country.

We additionally set out any regulatory exclusivity from which these products continue to benefit in the US, EU or Japan. Regulatory exclusivities presented below incorporate any pediatric extensions obtained. While EU regulatory exclusivity is intended to be applied throughout the EU, in some cases Member States have taken positions prejudicial to our exclusivity rights.

We caution the reader that there can be no assurance that we will prevail when we assert a patent in litigation and that there may be instances in which Sanofi determines that it does not have a sufficient basis to assert one or more of the patents mentioned in this report, for example in cases where a competitor proposes a formulation not appearing to fall within the claims of our formulation patent; a salt or crystalline form not claimed by our composition of matter patent; or an indication not covered by our method of use patent. See “Item 3. Key Information - D. Risk Factors - Risks Relating to Legal and Regulatory Matters - We rely on our patents and other proprietary rights to provide exclusive rights to market certain of our products, and if such patents and other rights were limited or circumvented, our financial results could be materially and adversely affected”.




SANOFI / FORM 20-F 2019	39

ITEM 4. INFORMATION ON THE COMPANY

As disclosed in Item 8 of this annual report, we are involved in significant litigation concerning the patent protection of a number of our products.


▪	Challenges to patented products


–	Abbreviated New Drug Applications (ANDAs)

In the US, generic companies have filed Abbreviated New Drug Applications (ANDAs) containing challenges to patents related to a number of our small molecule products. An ANDA is an application by a drug manufacturer to receive authority to market a generic version of another company’s approved product, by demonstrating that the purportedly generic version has the same properties (safety and other technical data) as the original approved product. As a result of regulatory protection of our safety and other technical data, ANDA applications are generally four years after FDA approval , and include a challenge to a patent listed in the FDA’s Orange Book. If the patent holder or licensee brings suit in response to the patent challenge within the statutory window, the FDA is barred from granting final approval to an ANDA during the 30 months following the expiry of the 5-year regulatory exclusivity (this bar is referred to in our industry as a “30-month stay”) unless, before the end of the 30 months, the parties reach settlement or a court decision has determined either that the ANDA does not infringe the listed patent or that the listed patent is invalid and/or unenforceable.

FDA approval of an ANDA after this 30-month period does not resolve outstanding patent disputes, but it does remove the regulatory impediments to a product launch by a generic manufacturer willing to take the risk of later being ordered to pay damages to the patent holder.

Accelerated ANDA-type procedures are potentially applicable to many, but not all, of the products we manufacture. See “- B.6.3. Regulatory Framework - 6.3.2. Biosimilars” and “- Regulation” above. We seek to defend our patent rights vigorously in these cases. Success or failure in the assertion of a given patent against a competing product is not necessarily predictive of the future success or failure in the assertion of the same patent - or a fortiori the corresponding foreign patent - against another competing product due to factors such as possible differences in the formulations of the competing products; intervening developments in law or jurisprudence; local variations in the patents; and differences in national patent law and legal systems. See “Item 3. Key Information - D. Risk Factors - Risks Relating to Legal and Regulatory Matters - We rely on our patents and other proprietary rights to provide exclusive rights to market certain of our products, and if such patents and other rights were limited or circumvented, our financial results could be materially and adversely affected”.


–	Section 505(b)(2) New Drug Applications in the US

Our products and patents are also subject to challenge by competitors via another abbreviated approval pathway, under section 505(b)(2) of the Federal Food, Drug, and Cosmetic Act. This provision expressly permits an applicant to rely, at least in part, on the FDA’s prior findings of safety and effectiveness of a drug that has obtained FDA approval. The FDA may still require applicants to provide additional preclinical or clinical data to ensure that differences from the reference drug do not compromise safety and effectiveness. This pathway allows for approval for a wide range of products, especially for those products that represent only a limited change from an existing approved drug. The 505(b)(2) pathway is distinct from the ANDA pathway, which allows for approval of a generic product based on a showing that it is equivalent to a previously approved product.

A 505(b)(2) applicant is required to identify the reference drug on which it relies, as well as to certify to the FDA concerning any patents listed for the referenced product in the Orange Book. Specifically, the applicant must certify in the application that, for each patent that claims the drug or a use of the drug for which the applicant is seeking approval : (a) there is no patent information listed for the reference drug (paragraph I certification); (b) the listed patent has expired for the reference drug (paragraph II certification); (c) the listed patent for the reference drug has not expired, but will expire on a particular date and approval is sought after patent expiration (paragraph III certification); or (d) the listed patent for the reference drug is invalid, unenforceable, or will not be infringed by the manufacture, use or sale of the product for which the 505(b)(2) NDA is submitted (paragraph IV certification).

A paragraph III certification may delay the approval of an application until the expiration of the patent. A paragraph IV certification generally requires notification of the patent owner and the holder of the NDA for the referenced product. If the patent owner or NDA holder brings patent litigation against the applicant within the statutory window, a 30-month stay is entered on the FDA’s ability to grant final approval to the 505(b)(2) applicant unless, before the end of the stay, a court decision or settlement determines the listed patent is invalid, not enforceable, and/or not infringed. A 505(b)(2) application may also be subject to non-patent exclusivity, and the FDA may be prohibited from giving final approval to a 505(b)(2) application until the expiration of all applicable non-patent exclusivity periods.

In the EU, a generic drug manufacturer may only reference the data of the regulatory file for the original approved product after data exclusivity has expired. However, there is no patent listing system in Europe comparable to the Orange Book, which would allow the patent holder to prevent the competent authorities from granting marketing authorization by bringing patent infringement litigation prior to approval. As a result, generic products may be approved for marketing following the expiration of marketing exclusivity without regard to the patent holder’s rights. Nevertheless, in most of these jurisdictions once the competing product is launched, and in some jurisdictions even prior to launch (once launch is imminent), the patent holder may seek an injunction against such marketing if it believes its patents are infringed. See Item 8 of this annual report.

B.7.2. Trademarks

Our products are sold around the world under trademarks that we consider to be of material importance in the aggregate. Our trademarks help to identify our products and to protect the sustainability of our growth. Trademarks are particularly important to the commercial success of our Consumer Healthcare business .

It is our policy to protect our trademarks for products and/or services of interest , in the countries where they are commercialized.

B.8. Production and raw materials

We have opted to manufacture the majority of our products in-house. There are three principal stages in our production process: the manufacture of active ingredients, the transformation of those ingredients into drug products or vaccines, and packaging those products.

Our general policy is to produce the majority of our active ingredients and principal drug products at our own plants in order to reduce our dependence on external suppliers. We also rely on third parties for the manufacture and supply of certain active ingredients, drug products and medical devices. Active ingredients are manufactured using raw materials sourced from suppliers who have been subject to rigorous selection and approval procedures, in accordance with international standards and our own internal directives. We have outsourced some of our production under supply contracts associated with acquisitions of products or businesses or with plant divestitures, or to establish a local presence to capitalize on growth in emerging markets. Our pharmaceutical subcontractors follow our general quality and logistics policies, as well as meeting other criteria. See ‘‘Item 3. Key Information - D. Risk Factors - Risks Relating to Our Business’’.

At the start of 2017 we launched our “Global External Manufacturing” team, to enhance the way we manage relations with our third-party suppliers of finished products.

We also obtain active ingredients from third parties under collaboration agreements. This applies in particular to the monoclonal antibodies developed with Regeneron.

Our pharmaceutical production sites are divided into three categories:


▪	global sites , which serve all markets: located mainly in Europe, these facilities are dedicated to the manufacture of our active ingredients, injectable products, and a number of our main solid-form products;


▪	regional sites, which serve markets at regional level, in Europe and particularly the BRIC-M countries (Brazil, Russia, India, China and Mexico), giving us a strong industrial presence in emerging markets; and


▪	local sites, whi ch serve their domestic market only.

Sanofi Pasteur produces vaccines at various sites, with the main locations situated in France, the United States, Canada, Mexico and China. The pharmaceutical site at Le Trait (France) also contributes to Sanofi Pasteur’s industrial operations by making available its sterile filling facilities.

All of our production facilities are good manufacturing practice (GMP) compliant, in line with international regulations.

Our principal sites approved by the FDA are:


▪	the Biologics facilities i n the United States (Allston MA, Framingham MA and Northborough MA), France (Lyon Gerland, Vitry-sur-Seine), Germany (Frankfurt) and Belgium (Geel);


▪	most of the chemical facilities that produce active ingredients, including those located in France (Aramon, Sisteron, Vertolaye, Saint-Aubin-les-Elbeuf), Germany (Frankfurt), Hungary (Ujpest) and Singapore (Jurong);


▪	the Injectables facilities in France (Le Trait), Italy (Anagni), Ireland (Waterford), Germany (Frankfurt) and the United States (Ridgefield NJ);


▪	the Pharmaceuticals facilities in France (Ambarès and Tours);


▪	the Consumer Healthcare facilities in France (Compiègne) and the United States (Chattanooga TN); and


▪	the Vaccines facilities in France (Marcy l’Étoile, Le Trait, Val-de-Reuil and Neuville-sur-Saône), the United States (Swift water PA) and Canada (Toronto).

Wherever possible, we seek to have multiple plants approved for the production of key active ingredients and our strategic finished products (this is the case with Lovenox ^® , and Dupixent ^® , for example).

In May 2010, Genzyme’s Allston facility in the United States entered into a consent decree with the US government following FDA inspections at the facility that resulted in observations and a warning letter raising Current Good Manufacturing Practices (CGMP) deficiencies.

The workplan was completed on March 31, 2016. The next step was a third-party certification process. Starting August 2017, the FDA has been conducting inspections of the facility and delivering favorable conclusions, as a result of which certification has been in place since October 4, 2017 .

The Allston facility is required to engage a third-party expert to audit its manufacturing operations for an additional period of at least five years. More details about our manufacturing sites are given below at section ‘‘D. Property, Plant and Equipment’’.

B.9. Insurance and risk coverage

We are protected by four key insurance programs, relying not only on the traditional corporate insurance and reinsurance market but also on our direct insurance company, Carraig Insurance DAC (Carraig).

These four key programs cover Property & Business Interruption, General & Product Liability, Stock and Transit, and Directors & Officers Liability.

Carraig participates in our coverage for various lines of insurance including Property & Business Interruption, Stock and Transit, and General & Product Liability. Carraig is run under the supervision of the Irish regulatory authorities, is wholly owned by Sanofi, and has sufficient resources to meet those portions of our risks that it has agreed to cover.

It sets premiums for our entities at market rates. Claims are assessed using the traditional models applied by insurance and reinsurance companies, and the company’s reserves are regularly verified and confirmed by independent actuaries.




SANOFI / FORM 20-F 2019	41

ITEM 4. INFORMATION ON THE COMPANY

Our Property & Business Interruption program covers all our entities worldwide, wherever it is possible to use a centralized program operated by Carraig. Through risk mutualization between our entities, this approach enables us to set tailored deductibles and covers to match local entities’ needs before market intervention. It also incorporates a prevention program, including a comprehensive site visit schedule covering our production, storage, research and distribution facilities and standardized repair and maintenance procedures across all sites.

The Stock and Transit program protects all goods owned by Sanofi while they are in transit nationally or internationally whatever the means of transport, and all our inventories wherever they are located. Sharing risk between our entities through Carraig means that we can set deductibles at appropriate levels, for instance differentiating between goods that require temperature controlled distribution and those that do not. We have developed a prevention program with assistance from experts, implementing best practices in this area at our distribution sites.

Our General & Product Liability program was renewed in 2019 for all our subsidiaries worldwide wherever it was possible to do so, despite reluctance in the insurance and reinsurance market to cover product liability risks for large pharmaceutical groups. For several years, insurers have been reducing product liability cover because of the difficulty of transferring risk for some products that have been subject to numerous claims. This applies to a few of our products and has led us to increase, year by year, the extent to which we self-insure.

The principal risk exposure for our pharmaceutical products is covered with low deductibles at country level, the greatest level of risk being retained. The level of risk self-insured by Sanofi (including via Carraig) before the market attachment point, enables us to retain control over the management and prevention of risk. Our negotiations with third-party insurers and reinsurers are tailored to our specific risks. In particular, they allow for differential treatment of products in the development phase, for the discrepancies in risk exposure between European countries and the United States, and for specific issues arising in certain jurisdictions such as generics coverage in the United States. Coverage is adjusted every year in order to take into account the relative weight of new product liability risks, such as those relating to rare diseases or to healthcare products which do not require marketing approval.

Our cover for risks that are not specific to the pharmaceutical industry (general liability) is designed to address the potential impacts of our operations.

For all the insurance programs handled by Carraig, outstanding claims are covered by provisions for the estimated cost of settling all claims incurred but not paid at the balance sheet date, whether reported or not, together with all related claims handling expenses. Where there is sufficient data history from Sanofi or from the market for claims made and settled, management - with assistance from independent actuaries - prepares an actuarial estimate of our exposure to unreported claims for the risks covered. The actuaries perform an actuarial valuation of the company’s IBNR (Incurred But Not Reported) and ALAE (Allocated Loss Adjustment Expense) liabilities at year end. Two ultimate loss projections (based upon reported losses and paid losses, respectively) are computed each year using various actuarial methods including the Bornhuetter-Ferguson method; those projections form the basis for the provisions set.

The Directors & Officers Liability program protects all legal entities under our control, and their directors and officers. Carraig is not involved in this program.

We also operate other insurance programs, but these are of much lesser importance than those described above.

All our insurance programs are backed by best in class insurers and reinsurers and are designed in such a way that we can integrate most newly acquired businesses without interruption of cover. Our cover has been designed to reflect our risk profile and the capacity available in the insurance market. By centralizing our major programs, we are able to provide world-class protection while reducing costs.

I TEM 4. INFORMATION ON THE COMPANY

B.10. Health, Safety and Environment

Our manufacturing and research operations are subject to increasingly stringent health, safety and environmental (HSE) laws and regulations. These laws and regulations are complex and rapidly changing, and Sanofi invests the necessary sums in order to comply with them. This investment, which aims to respect health, safety and the environment, varies from year to year.

Applicable environmental laws and regulations may require us to eliminate or reduce the effects of chemical substance discharge at our various sites. The sites in question may belong to Sanofi, and may be currently operational, or may have been owned or operational in the past. In this regard, Sanofi may be held liable for the costs of removal or remediation of hazardous substances on, under or in the sites concerned, or on sites where waste from activities has been stored, without regard to whether the owner or operator knew of or under certain circumstances caused the presence of the contaminants, or at the time site operations occurred the discharge of those substances was authorized.

As is the case for a number of companies in the pharmaceutical, chemical and intense agrochemical industries, soil and groundwater contamination has occurred at some of our sites in the past, and may still occur or be discovered at others. In Sanofi’s case, such sites are mainly located in the United States, Germany, France, Hungary, Italy and the United Kingdom. As part of a program of environmental surveys conducted over the last few years, detailed assessments of the risk of soil and groundwater contamination have been carried out at current and former Sanofi sites. In cooperation with national and local authorities, Sanofi regularly assesses the rehabilitation work required and carries out such work when appropriate. Long-term rehabilitation work is in progress or planned in Mount Pleasant, Portland in the United States; Frankfurt in Germany; Brindisi in Italy; Dagenham in the United Kingdom; Ujpest in Hungary; Beaucaire, Valernes, Limay, Neuville and Vitry in France; and on a number of sites divested to third parties and covered by contractual environmental guarantees granted by Sanofi.

We may also have potential liability for investigation and cleanup at several other sites. We have established provisions for the sites already identified and to cover contractual guarantees for environmental liabilities for sites that have been divested. In France specifically, we have provided the financial guarantees for environmental protection required under French regulations.

Potential environmental contingencies arising from certain business divestitures are described in Note D.22.d to the consolidated financial statements. In 2019, Sanofi spent €70 million on rehabilitating sites previously contaminated by soil or groundwater pollution.

Due to changes in environmental regulations governing site remediation, our provisions for remediation obligations may not be adequate due to the multiple factors involved, such as the complexity of operational or previously operational sites, the nature of claims received, the rehabilitation techniques involved, the planned timetable for rehabilitation, and the outcome of discussions with national regulatory authorities or other potentially responsible parties, as in the case of multiparty sites. Given the long industrial history of some of our sites and the legacy obligations arising from the past involvement of Aventis in the chemical and agrochemical industries, it is impossible to quantify the future impact of these laws and regulations with precision. See “Item 3.D. Risk Factors - Environmental Risks of Our Industrial Activities”.

We have established, in accordance with our current knowledge and projections, provisions for cases already identified and to cover contractual guarantees for environmental liabilities relating to sites that have been divested. In accordance with Sanofi standards, a comprehensive review is carried out once a year on the legacy of environmental pollution. In light of data collected during this review, we adjusted our provisions to approximately € 737 million as of December 31, 2019 versus € 680 million as of December 31, 2018 . The terms of certain business divestitures, and the environmental obligations and retained environmental liabilities relating thereto are described in Note D.22. to our consolidated financial statements.

To our knowledge, Sanofi did not incur any liability in 2019 for non-compliance with current HSE laws and regulations that could be expected to significantly jeopardize its activities, financial situation or operating income. We also believe that we are in substantial compliance with current HSE laws and regulations and that all the environmental permits required to operate our facilities have been obtained.

Regular HSE audits are carried out by Sanofi in order to assess compliance with standards (which implies compliance with regulations) and to initiate corrective measures (54 internal audits performed by 81 auditors in 2019 ). Moreover, around 200 specific visits were performed jointly with experts representing our insurers.

Sanofi has implemented a worldwide master policy on health, safety and environment to promote the health and well-being of the employees and contractors working on its sites and respect for the environment. We consider this master policy to be an integral part of our commitment to social responsibility. In order to implement this master policy, Sanofi key requirements have been drawn up in the key fields of HSE management, HSE leadership, safety in the workplace, process safety, occupational hygiene, health in the workplace and protection of the environment.

Health

From the development of compounds to the commercial launch of new drugs, Sanofi research scientists continuously assess the effect of products on human health. This expertise is made available to employees through two committees responsible for chemical and biological risk assessment. Sanofi’s COVALIS ( Comité des Valeurs Limites Internes Sanofi ) Committee is responsible for the hazard determination and classification of all active pharmaceutical ingredients and synthesis intermediates handled at Sanofi facilities. This covers all active ingredients handled in production at company sites or in processes sub-contracted for manufacture. Any important issues involving raw materials or other substances that lack established occupational exposure limits may also be reviewed. The COVALIS Committee determines the occupational exposure limits required within Sanofi. Our TRIBIO Committee is responsible for classifying all biological agents according to their degree of pathogenicity, and applies rules for their containment and the preventive measures to be respected throughout Sanofi. See “Item 3. Key Information - D. Risk Factors - Environmental Risks of Our Industrial Activities - Risks from the handling of hazardous materials could adversely affect our results of operations”.

Appropriate occupational hygiene practices and programs are defined and implemented in each site. These practices consist essentially of containment measures for collective and individual protection against exposure in all workplaces where chemical substances or biological agents are handled. All personnel are monitored with an appropriate medical surveillance program, based on the results of professional risk evaluations linked to their duties.




SANOFI / FORM 20-F 2019	43

ITEM 4. INFORMATION ON THE COMPANY

In addition, dedicated resources have been created to implement the EU Regulation on Registration, Evaluation, Authorization and Restriction of Chemicals (REACH). To fully comply with the new European Regulation on Classification, Labeling and Packaging of chemicals, Sanofi has registered the relevant hazardous chemical substances with the European Chemicals Agency (ECHA).

Safety

Sanofi has rigorous policies to identify and evaluate safety risks and to develop preventive safety measures, and methods for checking their efficacy. Additionally, Sanofi invests in training that is designed to instill in all employees a sense of concern for safety, regardless of their duties. These policies are implemented on a worldwide scale to ensure the safety of all employees and to protect their health. Each project, whether in research, development or manufacturing, is subject to evaluation procedures, incorporating the chemical substance and process data communicated by the COVALIS and TRIBIO Committees described above. The preventive measures are designed primarily to reduce the number and seriousness of work accidents and to minimize exposures involving permanent and temporary Sanofi employees as well as our sub-contractors.

The French chemical manufacturing sites in Aramon, Sisteron and Vertolaye, as well as the plants located in the Hoechst Industry Park in Frankfurt, Germany, and the chemical production site in Budapest, Hungary, are listed Seveso III (from the name of the European directive that deals with potentially dangerous sites through a list of activities and substances associated with classification thresholds). In accordance with French law on technological risk prevention, the French sites are also subject to heightened security inspections due to the toxic or flammable materials stored on the sites and used in the operating processes.

Risk assessments of processes and installations are drawn up according to standards and internal guidelines incorporating the best state of the art benchmarks for the industry. These assessments are used to fulfill regulatory requirements and are regularly updated. Particular attention is paid to any risk-generating changes such as process or installation changes, as well as changes in production scale and transfers between industrial or research units.

We have specialized process safety-testing laboratories that are fully integrated into our chemical development activities, apply methods to obtain the physico-chemical parameters of manufactured chemical substances (intermediate chemical compounds and active ingredients) and apply models to measure the effect of potentially leachable substances in the event of a major accident. In these laboratories the parameters for qualifying hazardous reactions are also determined, in order to define scale-up process conditions while transferring from development stage to industrial scale. All these data ensure that our risk assessments are relevant.

We believe that the safety management systems implemented at each site, the hazard studies carried out and the risk management methods implemented, as well as our third-party property insurance policies covering any third-party physical damage, are consistent with legal requirements and the best practices in the industry.

Environment

We have committed to an ambitious policy aimed at limiting the direct and indirect impacts of our activities on the environment, throughout the life cycle of our products. We have identified five major environmental challenges relating to our businesses: greenhouse gas emissions and climate disruption; water; pharmaceuticals in the environment; waste; and biodiversity.

The initiatives already implemented since 2010 are continuing, and we have been keen to give them fresh impetus through the Planet Mobilization program. Reflecting our environment strategy out to 2025, the program sets more ambitious targets for reducing environmental impacts across the entire value chain. Planet Mobilization is a global project that involves all of the Company’s resources in defining objectives and engaging with external partners.

Compared with 2015 figures, we are undertaking to halve our carbon emissions by the end of 2025 and reach carbon-neutral status by 2050 on our scope 1 & 2 (industrial, R&D and tertiary sites, including the medical rep fleet). We have also set ourselves the target of achieving sustainable water resource management, especially at sites which are under hydric stress. On this new scope, by the end of 2019 , we had reduced CO ₂ emissions by 12% and water consumption by 19%.

Overall waste recycling at sites is already above 72% and is expected to be more than 90% by the end of 2025. The discharge rate had dropped to 8% at the end of 2019 and we have committed to move towards a maximum of 1% by 2025. Biodiversity management at sites is also a priority, with the aim of making all employees aware of this challenge and implementing risk assessment and management plans at priority sites.

Finally, we are pursuing the policy we began in 2010 of managing pharmaceutical products in the environment throughout their life cycles. At the end of 2019, all priority chemical sites had been evaluated and were shown to present no risk to the environment. The assessment program was extended to other sites, starting with the pharmaceutical production sites. Since 2017, ten sites implemented the program.

In line with this approach, we have committed to the “Roadmap AMR 2020” initiative, which aims to combat microbial resistance to antibiotics. The initiative brings together thirteen of the major players in the pharmaceutical industry, and will involve co-producing reference guides and methodologies for sustainable management of antibiotics in the pharmaceutical sector. The initiative includes a specific commitment with respect to antibiotic production sites that are operated by signatories or their suppliers, involving firstly the definition and deployment of a shared framework for managing potential waste, and secondly the establishment of environmental thresholds. (See “Cautionary statement regarding forward-looking statements”).

For further information, refer to Note C. “Principal Alliances” to our consolidated financial statements.

C.2. Internal organization of activities

Sanofi and its subsidiaries collectively form a group organized around three activities: Pharmaceuticals, Consumer Healthcare and Vaccines.

Within Sanofi, responsibility for research and development (R&D) in their respective fields rests with Sanofi SA and Genzyme Corporation in Pharmaceuticals, and with Sanofi Pasteur and Sanofi Pasteur, Inc. in Vaccines. However, within our integrated R&D organization, strategic priorities are set and R&D efforts coordinated on a worldwide scale. In fulfilling their role in R&D, the aforementioned companies subcontract R&D to those of their subsidiaries that have the necessary resources. They also license patents, manufacturing know-how and trademarks to certain of their French and foreign subsidiaries. Those licensee subsidiaries manufacture, commercialize and distribute the majority of our products, either directly or via local distribution entities.

Our industrial property rights, patents and trademarks are mainly held by the following companies:


▪	Pharmaceuticals: San ofi, Sanofi Mature IP, Sanofi Biotechnology SAS (France), Sanofi-Aventis Deutschland GmbH (Germany), Ablynx (Belgium), and Genzyme Corporation and Bioverativ Inc. (US);

C.3. Financing and financial relationships between group companies

The Sanofi parent company raises the bulk of the Company’s external financing and uses the funds raised to meet, directly or indirectly, the financing needs of its subsidiaries. The parent company operates a cash pooling arrangement under which any surplus cash held by subsidiaries is managed centrally. There is also a centralized foreign exchange risk management system in place, whereby the parent company contracts hedges to meet the needs of its principal subsidiaries.

Consequently, at December 31, 2019 , the Sanofi parent company held 96% of our external financing and 87% of our surplus cash.

Sanofi European Treasury Center SA (SETC), a 100%-owned Sanofi subsidiary incorporated in 2012 under the laws of Belgium, is dedicated to providing financing and various financial services to our subsidiaries.

D/ Property, plant and equipment

As part of the process of transforming Sanofi and creating Global Business Units, we are continuing to adapt the organization of the Industrial Affairs department in support of our new business model. The Industrial Affairs department focuses on customer needs and service quality; the sharing of “Sanofi Manufacturing System” good manufacturing practices; the development of a common culture committed to quality; and the pooling of expertise within technology platforms, particularly in biological, injectable and pharmaceutical products.

Since January 2016, the Industrial Affairs department has also been responsible for Sanofi Global HSE and Global Supply Chain.

At the end of 2019 , we were carrying out industrial production at 73 sites in 32 countries:


▪	8 sites for o ur Biologics operations;


▪	9 sites for our Injectables operations;


▪	31 sites for our Pharmaceuticals operations;


▪	14 sites for our Consumer Healthcare operations; and


▪	11 sites for the industrial operations of Sanofi Pasteur in vaccines.

The quantity of units sold in 2019 , including in-house and outsourced production, was 4,561 million, comprising:


▪	Pharmaceuticals: 2,635 million units;


▪	Consumer Healthcare: 1,760 million units; and


▪	Vaccines: 166 million filled containers (syringes, vials and lyophilized products).

We believe that our production facilities are in compliance with all regulatory requirements, are properly maintained and are generally suitable for future needs. We regularly inspect and evaluate those facilities with regard to environmental, health, safety and security matters, quality compliance and capacity utilization. For more information about our property, plant and equipment, see Note D.3 to our consolidated financial statements, included at Item 18 of this annual report, and section “B.8.

D.3. Acquisitions, capital expenditures and divestitures

The carrying amount of our property, plant and equipment at December 31, 2019 was € 9,717 million. During 2019 , we invested € 1,261 million (see Note D.3. to our consolidated financial statements, included at Item 18 of this annual report), mainly in increasing capacity and improving productivity at our various production and R&D sites.

Our principal acquisitions, capital expenditures and divestitures in 2017 , 2018 and 2019 are described in Notes D.1. (“Impact of changes in the scope of consolidation”), D.3. (“Property, plant and equipment”) and D.4. (“Goodwill and other intangible assets”) to our consolidated financial statements, included at Item 18 of this annual report.

As of December 31, 2019 , our firm commitments in respect of future capital expenditures amounted to € 398 million. The principal locations involved were: for the Pharmaceuticals segment, the industrial facilities at Frankfurt (Germany), Le Trait, Maisons-Alfort and Compiègne (France), Cambridge (United States), Csanyikvölgy (Hungary), Origgio et Anagni (Italy) ; and for the Vaccines segment, the facilities at Toronto (Canada), Marcy-l’Étoile and Val de Reuil (France).

In the medium term and assuming no changes in the scope of consolidation, we expect to invest on average some €1.5 billion a year in property, plant and equipment. We believe that our own cash resources and the undrawn portion of our existing credit facilities will be sufficient to fund these expenditures.

Our principal ongoing capital expenditures are described below.

Biologics

In 2014, a dedicated Biologics platform was launched to develop synergies between Pharmaceuticals, Sanofi Pasteur, Sanofi Genzyme and our Biotherapeutics operations. This platform is helping us extend our footprint in biotechnologies by adopting a multi-disciplinary approach and improving capacity utilization. It also enables us to leverage our expertise in the production of biologics, from active ingredient to integrated manufacturing, including both the medicine itself and associated medical devices.

We have four dedicated biotechnology hubs: Paris/Lyon (France), Frankfurt (Germany), Geel (Belgium) and Boston (United States). The Bioatrium project, a joint venture between Sanofi and Lonza (Switzerland) set up in 2017 to increase bioproduction capacity, is proceeding on schedule. Exploiting the innovative techniques on which biotech relies, including cell and microbiological culture or the development of viral vectors, calls for highly specific knowledge and expertise backed by dedicated production platforms to support global product launches.

Injectables

Our Injectables platform is served by a network whose key sites are Frankfurt (Germany), Le Trait (France) and Waterford (Ireland).

The Waterford and Le Trait sites manufacture pre-filled Dupixent ^® syringes.

Our pre-filled syringes network delivers Lovenox ^® /Clexane ^® from Le Trait and Maisons-Alfort (France) to global markets, Csanyikvölgy (Hungary) mainly to EMA regulated markets and Ridgefield (USA) to the US market.

The Frankfurt facility is our principal site for the manufacture of diabetes treatments.

ITEM 4. INFORMATION ON THE COMPANY

Pharmaceuticals

The development of our General Medicines & Emerging Markets platform is built on a network of over 30 regional and local industrial sites in 21 countries, supporting growth in those markets.

Our Industrial Affairs Department has an ongoing policy of adapting industrial facilities to market needs. As part of this process, during 2019 we divested various facilities, including those at Villa Rica (Colombia) and Dubai (UAE).

Consumer Healthcare

The pharmaceutical industrial operations of our Consumer Healthcare (CHC) business are spread across a dedicated network. Global markets are supplied from our facilities at Compiègne (France) and Cologne (Germany). We have recently invested in projects to bring in-house various manufacturing operations related to our acquisition of Boeringher Ingelheim's CHC business, mainly to our sites at Compiègne (France) and Suzano (Brazil).

Vaccines (Sanofi Pasteur)

Sanofi Pasteur’s industrial operations are in a major investment phase, preparing for the upcoming growth of our influenza and Polio/Pertussis/Hib franchises. Major investments were launched during 2019 in France (including construction of a new influenza vaccine building at Val-de-Reuil), Canada (a new pertussis vaccine building), the US and Mexico.

Innovation and culture of industrial excellence

The ambition of our Industrial Affairs department is to continue to raise quality standards in Sanofi’s production activities, and to remain a world leader and a benchmark in the global pharmaceutical industry. To achieve this goal, all our activities share a common culture of industrial excellence, enshrined in the Sanofi Manufacturing System. This sets out a series of priorities (such as customer service, constant improvement, site network optimization and transverse optimization) that constitute our industrial vision and will be crucial to our mutual success.

Industrial Affairs has its own digital strategy, built on five pillars: Integrated Industrialization, Intelligent Quality, Connected Teams and Operations, Connected Factory, and Real-Time Supply Chain.

D.4. Office space

As part of the transformation of Sanofi, we are undertaking major real estate programs with two core objectives: to bring our teams together on single sites in new workspaces that favor agility, cross-fertilization and communication, and to rationalize office space while achieving a responsible environmental footprint.

Projects completed in 2019 included the rationalization of our sites in Lima (Peru), Dubai (UAE), Bordeaux (France), Zagreb (Croatia), Beijing (China), and Quito (Ecuador), and of other sites in Switzerland, Turkey and the UK. In the UK, we have implemented a masterplan that will see teams previously based in Oxford, Guildford and Maidenhead brought together on a single site to the west of London.

This transformation of workspaces to flexible mode has already reached over 19,000 of our people around the globe, and provides strong support for our various operations to attain their objectives. The rollout will cover all regions worldwide; projects are currently under way in Argentina, Saudi Arabia, Ivory Coast, Singapore, Shanghai and Hong Kong. We continue to divest orphan sites, and in 2019 sold around 20 plots or buildings no longer required for our operations .

A. Operating Results

A.1. Significant operating information

A.1.1. 2019 Overview

In a fast-changing industry environment, Sanofi continued its transformation during 2019, as we seek to deliver on our mission as a global healthcare leader at the cutting edge of innovation. The arrival of Paul Hudson as our new CEO in September 2019 was the catalyst for developing a new strategy to boost growth and our potential for innovation, based on four key priorities: (1) focus on growth; (2) lead with innovation; (3) accelerate efficiency; and (4) reinvent how we work. For further information about our new strategy, as announced in December 2019, refer to “- Item 4. - B.1. - Strategy”. Other significant events of the year are described below.

On January 7, 2019, Sanofi and Regeneron announced that they had restructured their 2015 global Immuno-Oncology Discovery and Development Agreement for new cancer treatments. The 2015 agreement was due to end in mid-2020, and this revision provides for ongoing collaborative development of two clinical stage bispecific antibodies. This gives Sanofi increased flexibility to advance its early-stage immuno-oncology pipeline independently, while Regeneron retains all rights to its other immuno-oncology discovery and development programs. On December 10, 2019, Sanofi and Regeneron announced their intention to simplify their antibody collaboration for Kevzara ^® (sarilumab) and Praluent ^® (alirocumab) by restructuring it into a royalty-based agreement. Under the proposed restructuring, Sanofi is expected to obtain sole global rights to Kevzara ^® and sole ex-US rights to Praluent ^® . Regeneron is expected to obtain sole US rights to Praluent ^® . Under the proposed terms of the agreement, each party will be solely responsible for funding development and commercialization expenses in their respective territories. These changes are expected to increase efficiency and streamline operations for the products. The existing collaboration relating to Dupixent ^® (dupilumab) and to SAR440340 (REGN3500) will remain unchanged.

On April 8, 2019, Sanofi and Alnylam concluded the research and option phase of the companies’ 2014 RNAi therapeutics alliance in rare genetic diseases. The material collaboration terms for patisiran, vutrisiran (ALN-TTRsc02) and fitusiran, as previously announced, continue unchanged. As part of this agreement, Alnylam will advance an additional investigational asset in a rare genetic disease through studies enabling the filing of an Investigational New Drug (IND) application. Sanofi will be responsible for any potential further development or commercialization of the asset.

On June 18, 2019, Sanofi and Google announced that they are establishing a new Innovation Lab with the ambition of transforming how future medicines and health services are delivered by tapping into the power of emerging technologies. The collaboration aims to change how Sanofi develops new treatments and will focus on three key objectives: to better understand patients and diseases, to increase Sanofi’s operational efficiency, and to improve the experience of Sanofi’s patients and customers.

On July 23, 2019, we announced that we had signed an agreement with Roche for the exclusive over-the-counter (OTC) rights to Tamiflu ^® for the prevention and treatment of influenza (flu) in the US. Under the terms of the agreement, Sanofi will be responsible for leading FDA negotiations for the OTC switch and subsequent exclusive marketing, scientific engagement and distribution of Tamiflu ^® in the US consumer health care market.

At the end of July 2019, given the primary endpoint results of blood sugar (HbA1c) reduction in the SOTA-CKD3 and SOTA-CKD4 studies, we provided notice to Lexicon that we were terminating our collaboration to develop, manufacture, and commercialize Zynquista ^TM in all ongoing global Type 1 and Type 2 diabetes programs.

On September 16, 2019, Sanofi and Abbott announced that they are partnering to integrate glucose sensing and insulin delivery technologies that would help to further simplify how people with diabetes manage their condition. The two companies will take an innovative approach to connected care by developing tools that combine FreeStyle Libre technology with insulin dosing information for future smart pens, insulin titration apps and cloud software.

On October 15, 2019, we inaugurated our new digital manufacturing facility in Framingham , Massachusetts (USA), one of the world’s first digital facilities using intensified, continuous biologics production technology. The new facility features leading-edge technology that connects the production process with research and development, paving the way for improved commercialization of important new medicines for patients.

On December 9, 2019, Sanofi and Synthorx, Inc. , a biotechnology company focused on developing treatments to prolong and improve the lives of people suffering from cancer and autoimmune disorders, entered into a definitive agreement under which Sanofi acquired all of the outstanding shares of Synthorx for $68 per share in cash, which represents an aggregate equity value of approximately $2.5 billion (on a fully diluted basis). The acquisition of Synthorx was completed on January 23, 2020.

ITEM 5. OPERATING AND FINANCIAL REVIEW AND PROSPECTS

In Pharmaceuticals, highlights of our research and development activities in 2019 included the launch of a pivotal Phase II study of SAR439859 (a selective estrogen receptor degrader) in breast cancer, and the entry into Phase III of cemiplimab (Libtayo ^® ), as an adjuvant in the treatment of cutaneous squamous cell carcinoma; venglustat (a GCS inhibitor), in autosomal dominant polycystic kidney disease (ADPKD); BIVV001, a recombinant coagulation factor for patients with hemophilia A; SAR408701 , an anti CEACAM-5 antibody drug conjugate as a second and third line treatment for non-small-cell lung cancer; and dupilumab (Dupixent ^® ) in chronic obstructive pulmonary disease. In Vaccines, the hexavalent pediatric vaccine Shan6 (diphtheria, tetanus, pertussis, polio, hepatitis B and hemophilus influenzae B) entered Phase III, along with the monoclonal antibody nirsevimab (collaboration with Medimmune) for the prevention of respiratory syncytial virus (RSV) and the vero-cell rabies vaccine VerorabVax ^® (VRVg).

Healthcare authorities granted marketing approval for a number of our products in 2019. The Democratic Republic of Congo (DRC) granted marketing approval for fexinidazole for the treatment of human African trypanosomiasis (HAT), more commonly known as sleeping sickness. In the United States, Cablivi ^® was approved in association with plasma exchange and immuno-suppression for the treatment of acquired thrombotic thrombocytopenic purpura (aTTP) in adults. In the United States and Europe, Dupixent ^® was approved for the treatment of severe atopic dermatitis in adolescents, and for the treatment of severe nasal polyps. In Europe, Dupixent ^® was approved as a treatment for severe asthma. The European Commission and the US FDA approved a new indication for Praluent ^® (alirocumab) to reduce cardiovascular risk in adults with established atherosclerotic cardiovascular disease. In Europe, conditional marketing approval was granted for Libtayo ^® (cemiplimab) in the treatment of advanced cutaneous squamous cell carcinoma (CSCC).

For further information about the pharmaceutical products and vaccines we sell, and about our research and development portfolio, refer to “- Item 4.B. - Business Overview”.

Our net sales for 2019 amounted to € 36,126 million, a year-on-year increase of 4.8 %. At constant exchange rates (CER ⁽¹⁾ ), net sales rose by 2.8 %, impacted by (i) the acquisition of Bioverativ’s rare blood disorder products and (ii) the divestment of our European generics business in 2018. At constant exchange rates and on a constant structure basis (CER/CS ⁽¹⁾ ), the growth rate was 3.6 %. Strong performances for Dupixent ^®, and for Vaccines across all geographies, combined with growth in Emerging Markets sales, more than offset lower sales of Lantus ^® and Established Prescription Products in mature markets.

Net income attributable to equity holders of Sanofi amounted to € 2,806 million in 2019, down 34.8 % year-on-year; this was due mainly to impairment losses charged against intangible assets in the period. Earnings per share was € 2.24 , 35.1 % lower than in 2018 . Business net income ⁽²⁾ was € 7,489 million, up 9.8 % on 2018 , while business earnings per share (business EPS ⁽²⁾ ) was 9.5 % higher than in 2018 at € 5.99 .

As of December 31, 2019 , we had reduced our net debt ⁽³⁾ to € 15,107 million (versus € 17,628 million as of December 31, 2018 ), due largely to the cash generated by our operations during the year. At the Annual General Meeting on April 28, 2020, we will ask our shareholders to approve a dividend of € 3.15 per share for the 2019 financial year, representing a payout of 52.6 % of our business net income.

ITEM 5. OPERATING AND FINANCIAL REVIEW AND PROSPECTS

A.1.2. Impacts of Competition from Generics and Biosimilars

Some of our flagship products continued to suffer sales erosion in 2019 due to competition from generics and biosimilars. We do not believe it is possible to state with certainty what level of net sales would have been achieved in the absence of generic competition.

A comparison of our consolidated net sales for the years ended December 31, 2019 and 2018 (see “- A.2. Results of Operations - Year Ended December 31, 2019 Compared with Year Ended December 31, 2018 ” below) for products affected by generic and biosimilar competition shows a loss of €912 million of net sales on a reported basis. Other parameters may have contributed to the loss of sales, such as a fall in the average selling price of certain products (e.g. Lantus ^® ).

The table below sets forth the impact by product.



( € million)	2019	2018	Change on a reported basis		Change on a reported basis (%)
Aprovel ^® Europe	113	108	5		+4.6	%
Lantus ^® Europe	584	684	(100	)	-14.6	%
Lovenox ^® Europe	709	870	(161	)	-18.5	%
Plavix ^® Europe	139	147	(8	)	-5.4	%
Renagel ^® / Renvela ^® Europe	51	60	(9	)	-15.0	%
Ambien ^® United States	42	45	(3	)	-6.7	%
Lantus ^® United States	1,149	1,614	(465	)	-28.8	%
Lovenox ^® United States	33	38	(5	)	-13.2	%
Renagel ^® / Renvela ^® United States	133	253	(120	)	-47.4	%
Allegra ^® Japan	115	112	3		+2.7	%
Amaryl ^® Japan	15	18	(3	)	-16.7	%
Aprovel ^® Japan	21	28	(7	)	-25.0	%
Lantus ^® Japan	25	29	(4	)	-13.8	%
Myslee ^® Japan	68	76	(8	)	-10.5	%
Plavix ^® Japan	131	156	(25	)	-16.0	%
Taxotere ^® Japan	7	9	(2	)	-22.2	%
Total	3,335	4,247	(912	)	-21.5	%

We expect the erosion caused by generic competition to continue in 2020 , with a negative impact on our net income. The products likely to be impacted include those that already faced generic competition in 2019, but whose sales can reasonably be expected to be subject to further sales erosion in 2020: Aprovel ^® , Lantus ^® , Lovenox ^® , Plavix ^® and Renagel ^® /Renvela ^® in Europe; Ambien ^® , Lantus ^® , Lovenox ^® , Renagel ^® / Renvela ^® and Taxotere ^® in the United States; and Allegra ^® , Amaryl ^® , Aprovel ^® , Lantus ^® , Myslee ^® , Plavix ^® and Taxotere ^® in Japan.

In 2019 , the aggregate consolidated net sales of those products in countries where generic competition currently exists or is expected in 2020 amounted to €3,335 million; this comprised €1,357 million in the United States (including €1,149 million in net sales of Lantus ^® and €133 million in net sales of Renagel ^® /Renvela ^® ); €1,596 million in Europe; and €382 million in Japan. The negative impact on our 2020 net sales is likely to represent a substantial portion of those sales, but the actual impact will depend on a number of factors such as the prices at which the products are sold and potential litigation outcomes.

A.1.3. Purchase Accounting Effects

Our results of operations and financial condition for the years ended December 31, 2019 , 2018 and 2017 have been significantly affected by our August 2004 acquisition of Aventis, our April 2011 acquisition of Genzyme, our 2018 acquisition of Bioverativ and certain other transactions. See “- A.1.11. Critical accounting and reporting policies - Business combinations” below for an explanation of the impact of business combinations on our results of operations.

The Bioverativ business combination has generated significant amortization of intangible assets (€ 488 million in 2019, and €430 million in 2018) and impairment of intangible assets (expenses of € 2,803 million in 2019). The Genzyme business combination has generated significant amortization of intangible assets (€727 million in 2019, €760 million in 2018, and €857 million in 2017) and impairment of intangible assets (expenses of €163 million in 2019, expenses of €183 million in 2018, and expenses of €16 million in 2017). The Aventis business combination has also generated significant amortization expenses (€197 million in 2019, €256 million in 2018, and €365 million in 2017).

In order to isolate the purchase accounting effects of all acquisitions and certain other items, we use a non-GAAP financial measure that we refer to as “business net income ” (see definition in “- A.1.5. Segment Information - 3. Business Net Income” below).

A.1.4. Sources of Revenues and Expenses

Revenues. Revenue arising from the sale of goods is presented in the income statement within Net sales . Net sales comprise revenue from sales of pharmaceutical products, consumer health care products, active ingredients and vaccines, net of sales returns, of customer incentives and discounts, and of certain sales-based payments paid or payable to the healthcare authorities. Returns, discounts, incentives and rebates are recognized in the period in which the underlying sales are recognized, as a reduction of sales revenue. See Note B.13.1. to our consolidated financial statements included at Item 18 of this annual report. We sell pharmaceutical products and vaccines directly, through alliances, and by licensing arrangements throughout the world. When we sell products directly, we record sales revenues as part of our consolidated net sales. When we sell products through alliances, the revenues reflected in our consolidated financial statements are based on the contractual arrangements governing those alliances. For more information about our alliances, see “- A.1.7. Financial Presentation of Alliances” below. When our products are sold by licensing arrangements, we receive royalty income that we record in Other revenues . The sales of non-

ITEM 5. OPERATING AND FINANCIAL REVIEW AND PROSPECTS

Sanofi products of our US based entity VaxServe are also presented in Other revenues ; see Note B.13.2. to the consolidated financial statements included at Item 18 of this annual report.

Cost of Sales. Our cost of sales consists primarily of the cost of purchasing raw materials and active ingredients, labor and other costs relating to our manufacturing activities, packaging materials, payments made under licensing agreements and distribution costs. We have license agreements under which we manufacture, sell and distribute products that are patented by other companies and license agreements under which other companies distribute products that we have patented. When we pay royalties, we record them in Cost of sales .

Operating Income. Our operating income reflects our revenues, our cost of sales and the remainder of our operating expenses, the most significant of which are research and development expenses and selling and general expenses. For our operating segments, we also measure our results of operations through an indicator referred to as “Business Operating Income,” which we describe below under “- A.1.5. Segment Information -2/Business Operating Income.”

A.1.5. Segment information

1/ Operating segments

In accordance with IFRS 8 (Operating Segments), the segment information reported by Sanofi is prepared on the basis of internal management data provided to the Chief Executive Officer, who is the chief operating decision maker. The performance of those segments is monitored individually using internal reports and common indicators. The operating segment disclosures required under IFRS 8 are provided in Notes B.26. and D.35 (“Segment Information”) to our consolidated financial statements, included at Item 18 of this annual report.

Sanofi has three operating segments: Pharmaceuticals, Consumer Healthcare and Vaccines.

The Pharmaceuticals segment comprises the commercial operations of the following global franchises: Specialty Care (Rare Diseases, Multiple Sclerosis, Oncology, Immunology and Rare Blood Disorders), and Primary Care (Diabetes, Cardiovascular, and Established Prescription Products), together with research, development and production activities dedicated to our Pharmaceuticals segment. This segment also includes associates whose activities are related to pharmaceuticals, in particular our share of Regeneron.

The Consumer Healthcare segment comprises, for all geographical territories, the commercial operations for our Consumer Healthcare products, together with research, development and production activities dedicated to those products.

The Vaccines segment comprises, for all geographical territories (including from January 1, 2017 certain territories previously included in the Sanofi Pasteur MSD joint venture) the commercial operations of Sanofi Pasteur, together with research, development and production activities dedicated to vaccines.

Inter-segment transactions are not material.

The costs of our global support functions (Medical Affairs, External Affairs, Finance, Human Resources, Legal Affairs, Information Solutions & Technologies, Sanofi Business Services, etc.) are managed centrally at group-wide level. The costs of those functions are presented within the “Other” category. That category also includes other reconciling items such as retained commitments in respect of divested activities.

2/ Business Operating Income

We report segment results on the basis of “business operating income”. This indicator is used internally by Sanofi’s chief operating decision maker to measure the performance of each operating segment and to allocate resources. For a definition of “business operating income”, and a reconciliation between that indicator and Income before tax and investments accounted for using the equity method , refer to Note D.35. to our consolidated financial statements.

We have applied IFRS 16 (Leases) with effect from January 1, 2019 (see Note A.2.1. to our consolidated financial statements). In 2019, business net income excludes the impact of first-time application of IFRS 16. Consequently, in determining business operating income we have (i) eliminated depreciation charged against right-of-use assets and (ii) added back lease expense, in order to achieve consistency with the prior-year presentation (given that we elected the modified retrospective approach on transition).

Our “business operating income margin” for 2019 was 27.0%, compared with 25.8% in 2018. Business operating income margin is a non-GAAP financial measure, which we define as the ratio of "business operating income" to Net sales .

Because our business operating income and business operating income margin are not standardized measures, they may not be directly comparable with the non-GAAP financial measures of other companies using the same or similar non-GAAP financial measures. Despite the use of non-GAAP measures by management in setting goals and measuring performance, these are non-GAAP measures that have no standardized meaning prescribed by GAAP.

3/ Business net income

We believe that understanding of our operational performance by our management and our investors is enhanced by reporting “business net income”. This non-GAAP financial measure represents business operating income, less net financial expenses and the relevant income tax effects.

Business net income for 2019 was €7,489 million, 9.8 % higher than in 2018 ( €6,819 million), and represented 20.7% of net sales (compared with 19.8% in 2018)

We also report “business earnings per share” (business EPS), a non-GAAP financial measure which we define as business net income divided by the weighted average number of shares outstanding. Business EPS was €5.99 for 2019 , 9.5 % higher than the 2018 figure of €5.47 , based on an average number of shares outstanding of 1,249.9 million for 2019 and 1,247.1 million for 2018 .

(d) Impacts of the new accounting standard on leases (IFRS 16), applied from January 1, 2019 using the simplified retrospective method without restatement of comparative periods. For comparative purposes, business net income continues to be reported in accordance with the lease accounting policies applicable under the previous standard (IAS 17).


(e)	For 2018 , this line comprises adjustments to our preliminary analysis of the direct and indirect impacts of US tax reform.


(f)	This line shows the effects of the divestment of our Animal Health business.


(g)	The implementation of the new accounting standard on leases (IFRS 16) on business earnings per share would have been -2 cents in 2019. This impact mainly comes from the amortization of the lease asset recognized on a straight-line basis while the interest expense decreases over the life of the lease.

The most significant reconciling items between our business net income and Net income attributable to equity holders of Sanofi relate to (i) the purchase accounting effects of our acquisitions and business combinations, particularly the amortization and impairment of intangible assets (other than software and other rights of an industrial or operational nature) and (ii) the impacts resulting from restructuring or major non-recurring transactions. We believe that excluding those impacts enhances an investor’s understanding of our underlying economic performance, because we do consider that the exclusion of these items allows to better reflect the entity’s ongoing operating performance.

The principal purchase accounting effects of acquisitions and business combinations on net income are:


▪	amortization and net impairment losses charged against intangible assets (other than software and other rights of an industrial or operational nature), net of taxes and non-controlling interests; and


▪	the incremental cost of sales incurred on the workdown of acquired inventories remeasured at fair value, net of taxes.




54	SANOFI / FORM 20-F 2019

ITEM 5. OPERATING AND FINANCIAL REVIEW AND PROSPECTS

We believe (subject to the limitations described below) that disclosing our business net income enhances the comparability of our operating performance, for the following reasons:

▪

the elimination of charges related to the purchase accounting effects of our acquisitions and business combinations (particularly amortization and impairment of finite-lived intangible assets, other than software and other rights of an industrial or operational nature) enhances the comparability of our ongoing operating performance relative to our peers in the pharmaceutical industry that carry those intangible assets (principally patents and trademarks) at low book values either because they are the result of in-house research and development that has already been expensed in prior periods or because they were acquired through business combinations that were accounted for as poolings-of-interest;


▪	the elimination of other effects related to business combination - such as the incremental cost of sales arising from the workdown of acquired inventories remeasured at fair value in business combinations, also improves the understanding of the ongoing operating performance;


▪	the elimination of restructuring costs and similar items enhances comparability because those costs are incurred in connection with reorganization and transformation processes intended to optimize our operations; and


▪	the elimination of impacts resulting from major non-recurring transactions - gains and losses on disposals, and costs and provisions associated with major litigation and any other major non-recurring items - improves comparability from one period to the next.

We remind investors, however, that business net income should not be considered in isolation from, or as a substitute for, Net income attributable to equity holders of Sanofi reported in accordance with IFRS. In addition, we strongly encourage investors and potential investors not to rely on any single financial measure but to review our financial statements, including the notes thereto, carefully and in their entirety.

We compensate for the material limitations described above by using business net income only to supplement our IFRS financial reporting and by ensuring that our disclosures provide sufficient information for a full understanding of all adjustments included in business net income.

A.1.6. Presentation of Net Sales

In the discussion below, we present our consolidated net sales for 2019 , and 2018 . We analyze our net sales among various categories, including by segment, business global units, franchise, product and geographical region. In addition to reported net sales, we analyze non-GAAP financial measures designed to isolate the impact on our net sales of currency exchange rates and changes in the structure of our group.

When we refer to changes in our net sales at constant exchange rates (CER), that means that we have excluded the effect of exchange rates by recalculating net sales for the relevant period using the exchange rates that were used for the previous period.

When we refer to changes in our net sales on a constant structure basis, that means that we eliminate the effect of changes in structure by restating the net sales for the previous period as follows:


▪	by including sales generated by entities or product rights acquired in the current period for a portion of the previous period equal to the portion of the current period during which we owned them, based on sales information we receive from the party from whom we make the acquisition;


▪	similarly, by excluding sales for a portion of the previous period when we have sold an entity or rights to a product in the current period; and


▪	for a change in consolidation method, by recalculating the previous period on the basis of the method used for the current period.

A presentation of consolidated net sales for 2018 compared with 2017 is available in our Form 20-F filed on March 8, 2019, Item 5, section "A.2.1. Net Sales". The analysis of the net sales in that section is comparable with the analysis presented in the present report as regards the presentation by segment, product, and geographical region. The presentation by franchise has changed for the Established Prescription Products franchise, which now includes total sales of Generics, previously presented separately. The presentation by Global Business units has also changed, as described in below in section "A.2.1.Net Sales".

A.1.7. Financial Presentation of Alliances

We have entered into a number of alliances for the development, co-promotion and/or co-marketing of our products. We believe that a presentation of our two principal alliances is useful to an understanding of our financial statements.

The financial impact of the alliances on our income statement is described in “- Results of Operations - Year Ended December 31, 2019 Compared with Year Ended December 31, 2018 ” and “- Year Ended December 31, 2018 Compared with Year Ended December 31, 2017 ”, in particular in “- Net Sales”, “- Other Revenues”, “- Share of Profit/Loss from Investments Accounted for using the Equity Method” and “- Net Income Attributable to Non-Controlling Interests”.

1/ Alliance arrangements with Regeneron Pharmaceuticals Inc. (Regeneron)

Collaboration agreements on human therapeutic antibodies

In November 2007, Sanofi and Regeneron signed two agreements (amended in November 2009) relating to human therapeutic antibodies: (i) the Discovery and Preclinical Development Agreement, and (ii) the License and Collaboration Agreement, relating to clinical development and commercialization. Sanofi had an option to develop and commercialize antibodies discovered by Regeneron under the collaboration.




SANOFI / FORM 20-F 2019	55

ITEM 5. OPERATING AND FINANCIAL REVIEW AND PROSPECTS

Discovery and development

Under the 2009 amended agreements, Sanofi funded the discovery and pre-clinical development of fully human therapeutic antibodies up to a maximum of $160 million per year through 2017. Because Sanofi decided not to exercise its option to extend the Discovery and Preclinical Development Agreement, that agreement expired on December 31, 2017.

Upon Sanofi ’s exercise of an option on an antibody under the Discovery and Preclinical Development Agreement, the antibody became a Licensed Product under the License and Collaboration Agreement, pursuant to which Sanofi and Regeneron co- develop the antibody with Sanofi initially being wholly responsible for funding the development program . On receipt of the first positive Phase III trial results for any antibody being developed under the License and Collaboration Agreement , the subsequent Phase III costs for that antibody are split 80% Sanofi, 20% Regeneron. Amounts received from Regeneron under those arrangements are recognized by Sanofi as a reduction in the line item Research and development expenses . Co-development with Regeneron of the antibodies Praluent ^® , Dupixent ^® , Kevzara ^® and REGN3500 (SAR440340) is ongoing under the License and Collaboration Agreement at this time .

Once a product begins to be commercialized, and provided that the share of quarterly results under the agreement represents a profit, Sanofi is entitled to an additional portion of Regeneron’s profit-share (capped at 10% of Regeneron’s share of quarterly profits) until Regeneron has paid 50% of the cumulative development costs incurred by the parties in the collaboration (see footnote g(ii) to the table provided in Note D.21.1. of our consolidated financial statements, "Off balance sheet commitments relating to operating activities").

On the earlier of (i) 24 months before the scheduled launch date or (ii) the first positive Phase III trial results, Sanofi and Regeneron share the commercial expenses of the antibodies co-developed under the License and Collaboration Agreement .

Commercialization

Sanofi recognizes all sales of the antibodies. Sanofi and Regeneron share co-promotion rights on sales of the co-developed antibodies. Profits and losses arising from commercial operations in the United States are split 50 /50. Outside the United States, Sanofi is entitled to between 55% and 65% of profits depending on sales of the antibodies, and bears 55% of any losses. The share of profits and losses due to or from Regeneron under the agreement is recognized within the line items Other operating income or Other operating expenses , which are components of operating income. In addition, Regeneron is entitled to receive payments of up to $250 million contingent on the attainment of specified levels of aggregate sales on all antibodies outside the United States.

Amendments to the collaboration agreements

In January 2018, Sanofi and Regeneron signed a set of amendments to their collaboration agreements, including an amendment that allowed for the funding of additional programs on Dupixent ^® and REGN3500 (SAR440340) with an intended focus on extending the current range of indications, finding new indications, and improving co-morbidity between multiple pathologies.

On December 10, 2019, Sanofi and Regeneron announced their intention to simplify their antibody collaboration, including a shift to a royalty-based arrangement for Kevzara ^® (sarilumab) and Praluent ^® (alirocumab). Under the proposed restructuring, Sanofi is expected to obtain sole global rights to Kevzara ^® and sole ex-US rights to Praluent ^® . Regeneron is expected to obtain sole US rights to Praluent ^® . Each party will be solely responsible for funding development and commercialization expenses in their respective territories. These changes are expected to increase efficiency and streamline operations for the products. The existing collaboration relating to Dupixent ^® (dupilumab) and to SAR440340 (REGN3500) will remain unchanged.

Immuno-oncology (IO) collaboration agreements

On July 1, 2015, Sanofi and Regeneron signed two agreements - the IO Discovery and Development Agreement and the IO License and Commercialization Agreement (IO LCA) - relating to new antibody cancer treatments in the field of immuno-oncology. As part of the agreements, Sanofi made an upfront payment of $640 million to Regeneron.

The two companies agreed to invest approximately $1 billion from discovery through proof of concept (POC) development (usually a Phase IIa study) of monotherapy and novel combinations of immuno-oncology antibody candidates to be funded 25% by Regeneron ( $250 million ) and 75% by Sanofi ( $750 million ). The two companies also agreed to reallocate $75 million (spread over three years ) to immuno-oncology antibody research and development from Sanofi’s $160 million annual contribution to their existing antibody discovery collaboration.

An Amended IO Discovery Agreement, effective from December 31, 2018, was signed on January 2, 2019 . It narr ows the scope of the existing discovery and development activities conducted by Regeneron ("IO Development Activities") under the original 2015 IO Discovery and Development Agreement to developing therapeutic bispecific antibodies targeting (i) BCMA and CD3 (the "BCMAxCD3 Program") and (ii) MUC16 and CD3 (the "MUC16xCD3 Program") through clinical proof-of-concept. The Amended IO Discovery Agreement provided for Sanofi's payment of $462 million to Regeneron as consideration for (x) the termination of the 2015 IO Discovery Agreement, (y) the prepayment for certain IO Development Activities regarding the BCMAxCD3 Program and the MUC16xCD3 Program, and (z) the reimbursement of costs incurred by Regeneron under the 2015 IO Discovery Agreement during the fourth quarter of 2018. This gives Sanofi increased flexibility to advance its early-stage immuno-oncology pipeline independently, while Regeneron retains all rights to its other immuno-oncology discovery and development programs.

The ongoing development and commercialization collaboration on Libtayo ^® (cemiplimab) is unaffected by the amendments to the IO Discovery and Development Agreement.

Upon establishment of POC, or when the allocated funding has been expended, whichever is earlier, Sanofi can exercise its opt-in rights to further develop and commercialize under the IO LCA the two candidates derived from the amended IO Discovery Agreement. If Sanofi exercises its opt-in rights with respect to the BCMAxCD3program, Sanofi will lead the development and global commercialization of BCMAxCD3 candidate antibody and fund the development costs in full; Regeneron will refund 50% of those costs provided that the share of quarterly results under the IO LCA represents a profit, subject to a cap set at 10% of Regeneron’s profit-share. If Sanofi exercises its opt-in rights with respect to the MUC16xCD3 program, Regeneron will lead development worldwide and commercialization in the United States; development costs and global profits, will be shared 50 /50 between Sanofi and Regeneron.

On the earlier of (i) 24 months before the scheduled launch date or (ii) the first positive Phase III trial results, Sanofi and Regeneron will share the commercial expenses of the antibodies co-developed under the license agreement.




56	SANOFI / FORM 20-F 2019

ITEM 5. OPERATING AND FINANCIAL REVIEW AND PROSPECTS

Libtayo ^® (cemiplimab)

Under the 2015 IO LCA as amended in January 2018, Sanofi and Regeneron committed funding of no more than $1,640 million , split on a 50 /50 basis ( $820 million per company), for the development of REGN2810 (cemiplimab, trademark Libtayo ^® ), a PD-1 inhibitor antibody. Regeneron is responsible for the commercialization of Libtayo ^® in the United States, and Sanofi in all other territories.

The IO LCA also provided for a one-time milestone payment of $375 million by Sanofi to Regeneron in the event that sales of a PD-1 product and any other collaboration antibody sold for use in combination with a PD-1 product were to exceed, in the aggregate, $2 billion in any consecutive 12-month period.

Under the IO License and Commercialization Agreement (IO LCA) Sanofi and Regeneron share equally in profits and losses in connection with the commercialization of collaboration products , except that Sanofi is entitled to an additional share of profits capped at 10% of the share of Regeneron’s quarterly profits to reimburse Sanofi of up to 50% of the clinical development costs funded by Sanofi under the IO Discovery Agreement, as amended.

On September 21, 2018, the US Food and Drug Administration (FDA) approved Libtayo ^® (cemiplimab) for the treatment of patients with metastatic cutaneous squamous cell carcinoma (CSCC) or locally advanced CSCC who are not candidates for curative surgery or curative radiation. Libtayo ^® is a fully-human monoclonal antibody targeting the immune checkpoint receptor PD-1 (programmed cell death protein-1) and is the first and only treatment specifically approved and available for advanced CSCC in the US. In July 2019, the European Medicines Agency (EMA) granted marketing authorization for Libtayo ^® for patients with metastatic or locally advanced CSCC who are not candidates for surgery.

In addition to advanced CSCC, clinical trials are ongoing to investigate cemiplimab in non small cell lung cancer, basal cell carcinoma, cervical cancer, head and neck squamous cell carcinoma, melanoma, colorectal cancer, prostate cancer, multiple myeloma, Hodgkin’s disease and non-Hodgkin lymphoma. Those potential indications are still investigational, and the safety and efficacy of Libtayo ^® have not been evaluated by any regulatory authority for any of them.

Investor agreement

In January 2014, Sanofi and Regeneron amended the investor agreement that has existed between the two companies since 2007. Under the terms of the amendment, Sanofi accepted various restrictions. Sanofi is bound by certain “standstill” provisions, which contractually prohibit Sanofi from seeking to directly or indirectly exert control of Regeneron or acquiring more than 30% of Regeneron’s capital stock (consisting of the outstanding shares of common stock and the shares of Class A stock). This prohibition will remain in place until the earlier of (i) the later of the fifth anniversaries of the expiration or earlier termination of the Zaltrap ^® collaboration agreement with Regeneron (related to the development and commercialization of Zaltrap ^® ) or the collaboration agreement with Regeneron on monoclonal antibodies (see “Collaboration agreements on human therapeutic antibodies” above), each as amended and (ii) other specified events.

Sanofi also agreed to vote as recommended by Regeneron’s Board of Directors, except that it may elect to vote proportionally with the votes cast by all of Regeneron’s other shareholders with respect to certain change-of-control transactions, and to vote in its sole discretion with respect to liquidation or dissolution, stock issuances equal to or exceeding 20% of the outstanding shares or voting rights of Regeneron’s Class A Stock and Common Stock (taken together), and new equity compensation plans or amendments if not materially consistent with Regeneron’s historical equity compensation practices. As soon as it had passed the threshold of 20% ownership of the capital stock, Sanofi exercised its right to designate an independent director, who was appointed to the Board of Directors of Regeneron. The interest held by Sanofi in Regeneron has been consolidated by the equity method since April 2014. On the conditions set out in the Amended Investor Agreement of January 2014, Sanofi’s right to designate a Regeneron board member was contingent on Sanofi maintaining its percentage share of Regeneron’s outstanding capital stock (measured on a quarterly basis) at a level no lower than the highest percentage level previously achieved, with the maximum requirement capped at 25% . In addition, Sanofi’s interest in Regeneron was subject to a lock-up clause. Those restrictions were amended by the letter agreement of January 2018 (see below).

At Sanofi’s request, pursuant to the Amended Investor Agreement, Regeneron appointed a new independent director, N. Anthony “Tony” Coles, M.D. to its Board of Directors in January 2017 as a Sanofi designee. The Amended Investor Agreement also gives Sanofi the right to receive certain reasonable information as may be agreed upon by the parties and which will facilitate Sanofi’s ability to account for its investment in Regeneron using the equity method of accounting under IFRS.

In January 2018, Sanofi and Regeneron announced (i) amendments to their collaboration agreements on human therapeutic antibodies; (ii) amendments to the IO LCA on the development of cemiplimab (REGN2810); and (iii) a limited waiver and amendment of the Amended Investor Agreement (the Amended and Restated Investor Agreement) pursuant to a letter agreement (the “2018 Letter Agreement”).

Pursuant to the 2018 Letter Agreement, Regeneron agreed to grant a limited waiver of the lock-up clause and the obligation to maintain the “Highest Percentage Threshold” in the Amended and Restated Investor Agreement between the companies, so that Sanofi may elect to sell a small percentage of the Regeneron common stock it owns to fund a portion of the cemiplimab and dupilumab development expansion. This waiver will allow Sanofi to sell up to an aggregate of 1.4 million shares of Regeneron common stock to Regeneron in private transactions through the end of 2020. If Regeneron decides not to purchase the shares, Sanofi will be allowed to sell those shares on the open market, subject to certain volume and timing limitations. Upon expiration of the limited waiver under the 2018 Letter Agreement, the Amended and Restated Investor Agreement will be amended to define “Highest Percentage Threshold” as the lower of (i) 25% of Regeneron outstanding shares of Class A Stock and Common Stock (taken together) and (ii) the higher of (a) Sanofi’s percentage ownership of Class A Stock and Common Stock (taken together) on such termination date and (b) the highest percentage ownership of Regeneron outstanding shares of Class A Stock and Common Stock (taken together) Sanofi attains following such termination date.

As of December 31, 2019 , Sanofi had sold 530,172 shares of Regeneron stock to Regeneron out of the 1.4 million shares covered by the 2018 Letter Agreement.




SANOFI / FORM 20-F 2019	57

ITEM 5. OPERATING AND FINANCIAL REVIEW AND PROSPECTS

In December 2019, Sanofi announced that on expiration of the lock-up term and as defined in the Amended and Restated Investor Agreement as amended by the 2018 Letter Agreement (i.e. in principle after December 20, 2020), Sanofi may dispose of its entire interest in Regeneron or of some of the shares of common stock held, on any single occasion or from time to time, via public offering or market transactions or a private sale, using derivatives or other means, at prices and on other terms acceptable to Sanofi depending on Sanofi’s capital allocation priorities and alternative investment opportunities, market conditions, the price of Regeneron common stock, and any other factors judged relevant by Sanofi with respect to its investment in Regeneron. Those provisions will be implemented in accordance with the Amended and Restated Investor Agreement as amended by the 2018 Letter Agreement, including the restrictions contained in Section 5 of the Amended and Restated Investor Agreement.

2/ Alliance arrangements with Bristol-Myers Squibb (BMS)

Two of Sanofi’s leading products were jointly developed with BMS: the anti-hypertensive agent irbesartan (Aprovel ^® /Avapro ^® /Karvea ^® ) and the anti-atherothrombosis treatment clopidogrel bisulfate (Plavix ^® /Iscover ^® ).

On September 27, 2012, Sanofi and BMS signed an agreement relating to their alliance following the loss of exclusivity of Plavix ^® and Avapro ^® /Avalide ^® in many major markets.

Under the terms of this agreement, effective January 1, 2013, BMS returned to Sanofi its rights to Plavix ^® and Avapro ^® /Avalide ^® in all markets worldwide with the exception of Plavix ^® in the United States and Puerto Rico, giving Sanofi sole control and freedom to operate commercially in respect of those products. In exchange, BMS received royalty payments on Sanofi’s sales of branded and unbranded Plavix ^® and Avapro ^® /Avalide ^® worldwide (except for Plavix ^® in the United States and Puerto Rico) until 2018, and also received a payment of $200 million from Sanofi in December 2018, part of which is for buying out the non-controlling interests (see Note D.18.). Rights to Plavix ^® in the United States and Puerto Rico remain unchanged and continued to be governed by the terms of the original agreement until March 2020.

In all of the territories managed by Sanofi (including the United States and Puerto Rico for Avapro ^® /Avalide ^® ) as defined in the new agreement, Sanofi recognized in its consolidated financial statements the revenue and expenses generated by its own operations. Since January 2019 onwards, there has no longer been any share of profits reverting to BMS subsidiaries (previously presented within Net income attributable to non-controlling interests in the income statement).

In the territory managed by BMS (United States and Puerto Rico for Plavix ^® ), Sanofi recognizes its share of profits and losses within the line item Share of profit/(loss) from investments accounted for using the equity method (see also Item 8. for recent changes).

A.1.8. Impact of Exchange Rates

We report our consolidated financial statements in euros. Because we earn a significant portion of our revenues in countries where the euro is not the local currency, our results of operations can be significantly affected by exchange rate movements between the euro and other currencies, primarily the US dollar and, to a lesser extent, the Japanese yen, and currencies in emerging countries. We experience these effects even though certain of these countries do not account for a large portion of our net sales. In 2019 , we earned 35.3 % of our net sales in the United States. An increase in the value of the US dollar against the euro has a positive impact on both our revenues and our operating income. A decrease in the value of the US dollar against the euro has a negative impact on our revenues, which is not offset by an equal reduction in our costs and therefore negatively affects our operating income. A variation in the value of the US dollar has a particularly significant impact on our operating income, which is higher in the United States than elsewhere, and on the contribution to net income of our collaborations with Regeneron and BMS in the United States (see “- A.1.7. Financial Presentation of Alliances” above).

For a description of arrangements entered into to manage operating foreign exchange risks as well as our hedging policy, see “Item 11. Quantitative and Qualitative Disclosures about Market Risk”, and “Item 3. Key Information - D. Risk Factors - Risks Related to Financial Markets - Fluctuations in currency exchange rates could adversely affect our results of operations and financial condition”.

A.1.9. Divestments

There were no material divestments in 2019.

On September 30, 2018, Sanofi finalized the divestment of Zentiva, its European Generics business, generating a pre-tax gain of €510 million euros in 2018.

On January 1, 2017, Sanofi and Boehringer Ingelheim (BI) finalized the strategic transaction agreed in June 2016, involving the exchange of our Animal Health business (Merial) for BI’s Consumer Healthcare business. After final enterprise value adjustments, the exchange values of the two businesses effectively transferred during 2017 were determined to be €10,557 million for Sanofi’s Animal Health business and €6,239 million for BI’s Consumer Healthcare business. The divestment of the Animal Health business generated an after-tax gain of €4,643 million in 2017.

For further details about the divestments mentioned above, see Note D.1. and D.2. to our consolidated financial statements included at Item 18 of the annual report for the period in which the divestment occurred.

ITEM 5. OPERATING AND FINANCIAL REVIEW AND PROSPECTS

A.1.10. Acquisitions

The impacts of the acquisitions carried out in 2019 are not material to the Sanofi consolidated financial statements.

Sanofi acquired Bioverativ Inc. (“Bioverativ”) on March 8, 2018 for $11.6 billion (€9.4 billion). The final purchase price allocation resulted in the recognition of goodwill amounting to €2,676 million. The contributions from Bioverativ to net sales and business operating income of the Pharmaceuticals segment in 2018 amount to €892 million and €389 million, respectively. Over the same period, Bioverativ made a negative contribution of €325 million to net profit, including expenses charged during the period relating to the fair value remeasurement of assets recognized at the acquisition date. During the year ended December 31, 2018, Bioverativ generated net sales of €1,068 million. The net cash outflow on this acquisition amounted to €8,932 million, and is recorded within Acquisitions of consolidated undertakings and investments accounted for using the equity method in the consolidated statements of cash flows.

Sanofi acquired Ablynx on May 14, 2018 for €3,897 million. The final purchase price allocation resulted in the recognition of goodwill amounting to €1,360 million. The impacts of this acquisition on Sanofi’s business operating income and consolidated net income for the year ended December 31, 2018 are not material. The net cash outflow on this acquisition amounted to €3,639 million, and is recorded within Acquisitions of consolidated undertakings and investments accounted for using the equity method in the consolidated statements of cash flows.

In 2019 , Sanofi sold shares in the biopharmaceutical company Regeneron with a carrying amount of € 33 million, compared with € 24 million in 2018 . Sanofi had acquired shares in Regeneron in 2017 (at a cost of €184 million). Our investment in Regeneron had a carrying amount of € 3,342 million as of December 31, 2019 , compared with € 3,055 million as of December 31, 2018 , and € 2,496 million as of December 31, 2017 (see Note D.1. to our consolidated financial statements). This represents an equity interest of 21.2 % as of December 31, 2019 , compared with 21.7 % as of December 31, 2018 , and 22.2 % as of December 31, 2017 .

In 2017, as part of the strategic transaction between Sanofi and Boehringer Ingelheim (BI), we acquired BI’s Consumer Healthcare business. The goodwill arising on that acquisition represents (i) the capacity to draw on a specialized structure to refresh the existing product portfolio; (ii) the competencies of the staff transferred to Sanofi; (iii) the benefits derived from the creation of new growth platforms; and (iv) the expected future synergies and other benefits from combining the CHC operations of BI and Sanofi. The tax-deductible portion of goodwill amounted to €1,876 million out of total goodwill of €2,222 million. This business generated sales of €1,407 million in the year ended December 31, 2017.

On August 25, 2017, Sanofi acquired 100% of Protein Sciences, a biotechnology company headquartered in Meriden, Connecticut (United States). The principal product of Protein Sciences is Flublok ^® , the only recombinant protein-based influenza vaccine approved by the FDA in the United States. The acquisition price included two contingent purchase consideration elements of €42 million each. The impacts of this acquisition on Sanofi’s business operating income and consolidated net income for the year ended December 31, 2017 were not material.

For further information about the acquisitions mentioned above, see Notes D.1. and D.2. to our consolidated financial statements included at Item 18 of the annual report for the period in which the acquisition occurred.

A.1.11. Critical accounting and reporting policies

Our consolidated financial statements are affected by the accounting and reporting policies that we use. Certain of our accounting and reporting policies are critical to an understanding of our results of operations and financial condition, and in some cases the application of these critical policies can be significantly affected by the estimates, judgments and assumptions made by management during the preparation of our consolidated financial statements. The accounting and reporting policies that we have identified as fundamental to a full understanding of our results of operations and financial condition are the following:

1/ Revenue recognition

Our policies with respect to revenue recognition are discussed in Note B.13. to our consolidated financial statements included at Item 18 of this annual report. Revenue arising from the sale of goods is presented in the income statement within Net sales . Net sales comprise revenue from sales of pharmaceutical products, consumer healthcare products, active ingredients and vaccines, net of sales returns, of customer incentives and discounts, and of certain sales-based payments paid or payable to the healthcare authorities. In accordance with IFRS 15 (Revenue from Contracts with Customers), such revenue is recognized when Sanofi transfers control over the product to the customer. Control refers to the ability to direct the use of, and obtain substantially all of the remaining benefits from the products. For the vast majority of contracts, revenue is recognized when the product is physically transferred, in accordance with the delivery and acceptance terms agreed with the customer.

For contracts entered into by Sanofi Pasteur, transfer of control is usually determined by reference to the terms of release (immediate or deferred) and acceptance of batches of vaccine.

As regards contracts with distributors, Sanofi does not recognize revenue when the product is physically transferred to the distributor in case of products sold on consignment, or if the distributor acts as an agent. In such cases, revenue is recognized when control is transferred to the end customer and the distributor’s commission is presented within the line item Selling and general expenses in the income statement.

We offer various types of price reductions on our products. In particular, products sold in the United States are covered by various programs (such as Medicare and Medicaid) under which products are sold at a discount. Rebates are granted to healthcare authorities, and under contractual arrangements with certain customers. Some wholesalers are entitled to chargeback incentives based on the selling price to the end customer, under specific contractual arrangements. Cash discounts may also be granted for prompt payment. The discounts, incentives and rebates described above are estimated on the basis of specific contractual arrangements with our customers or of specific terms of the relevant regulations and/or agreements applicable for transactions with healthcare authorities, and of assumptions about the attainment of sales targets. We also estimate the amount of sales returns, on the basis of contractual sales terms and reliable historical data. Discounts, incentives, rebates and sales returns are recognized in the period in which the underlying sales are recognized within Net Sales , as a reduction of gross sales. For additional details regarding the financial impact of discounts, incentives, rebates and sales returns, see Note D.23. to our consolidated financial statements included at Item 18 of this annual report.

Revenues from non-Sanofi products, mainly comprising royalty income from license arrangements and sales of non-Sanofi products by our US-based entity VaxServe, are presented within Other revenues .




SANOFI / FORM 20-F 2019	59

ITEM 5. OPERATING AND FINANCIAL REVIEW AND PROSPECTS

2/ Business combinations

As discussed in Note B.3. “Business combinations and transactions with non-controlling interests” to our consolidated financial statements included at Item 18 of this annual report, business combinations are accounted for by the acquisition method. The acquiree’s identifiable assets and liabilities that satisfy the recognition criteria of IFRS 3 (Business Combinations) are measured initially at their fair values as at the acquisition date, except for (i) non-current assets classified as held for sale, which are measured at fair value less costs to sell and (ii) assets and liabilities that fall within the scope of IAS 12 (Income Taxes) and IAS 19 (Employee Benefits). Business combinations completed on or after January 1, 2010 are accounted for in accordance with the revised IFRS 3 and the revised IAS 27, (Consolidated and Individual Financial Statements), now superseded by IFRS 10 (Consolidated Financial Statements). In particular, contingent consideration payable to former owners agreed in a business combination, e.g. in the form of payments upon the achievement of certain R&D milestones, is recognized as a liability at fair value as of the acquisition date irrespective of the probability of payment. If the contingent consideration was originally recognized as a liability, subsequent adjustments to the liability are recognized in profit or loss (see Note D.18. “Liabilities related to business combinations and non-controlling interests” to our consolidated financial statements included at Item 18 of this annual report).

3/ Impairment of goodwill and intangible assets

As discussed in Note B.6. “Impairment of property, plant and equipment, intangible assets, and investments accounted for using the equity method” and in Note D.5. “Impairment of intangible assets and property, plant and equipment” to our consolidated financial statements included at Item 18 of this annual report, we test our intangible assets for impairment periodically or when there is any internal or external indication of impairment, which indicators could include primarily but not exclusively (i) increased market competition resulting from (for example) the introduction of a competitor’s product; (ii) earlier than expected loss of exclusivity; (iii) increased pricing pressure; (iv) restrictions imposed by regulatory authorities on the manufacture or sale of a product; (v) delay in the projected launch of a product; (vi) different from expected clinical trial results; (vii) higher than expected development costs or (viii) lower economic performance than expected.

We test for impairment on the basis of the same objective criteria that were used for the initial valuation. Our initial valuation and ongoing tests are based on the relationship of the value of our projected future cash flows associated with the asset to either the purchase price of the asset (for its initial valuation) or the carrying amount of the asset (for ongoing tests for impairment).

Significant underlying assumptions requiring the exercise of considerable judgement are used in the future cash flow projections so as to determine the recoverability of intangible assets, including primarily but not exclusively (i) therapeutic class market growth drivers; (ii) expected impacts from competing products (including but not exclusively generics and biosimilars); (iii) projected pricing and operating margin levels; (iv) likely changes in the regulatory, legal or tax environment; and (v) management’s estimates of terminal growth or attrition rates.

The recoverable amounts of intangible assets related to research and development projects are determined based on future net cash flows, which reflect the development stage of the project and the associated probability of success of marketization of the compound.

The projected cash flows are discounted to present value using a discount rate which factors in the risks inherent in projected cash flows.

Changes in facts and circumstances, assumptions and/or estimates may lead to future additional impairment losses or reversal of impairment previously recorded.

Key assumptions relating to goodwill impairment are the perpetual growth rate, the probability of success of current research and development projects, and more generally on company’s ability to renew the product portfolio in the longer term and the post-tax discount rate. Any changes in key assumptions could result in an impairment charge. A sensitivity analysis to the key assumptions is disclosed in Note D.5. “Impairment of intangible assets and property, plant and equipment” to our consolidated financial statements included at Item 18 of this annual report.

4/ Contingent consideration receivable

As described in Note B.8.1 and D.7.2 to our consolidated financial statements included at Item 18 of this annual report, contingent consideration receivable such as earn-outs on disposals, for example in the form of a percentage of future sales of the acquirer, are recognized as an asset at fair value as of the date of divestment. Subsequent remeasurements of the fair value of the asset are recognized in profit or loss.

5/ Pensions and post-retirement benefits

As described in Note B.23. “Employee benefit obligations” to our consolidated financial statements included at Item 18 of this annual report, we recognize our pension and retirement benefit commitments as liabilities on the basis of an actuarial estimate of the rights vested in employees and retirees at the end of the reporting period, net of the fair value of plan assets held to meet these obligations. We prepare this estimate at least on an annual basis taking into account financial assumptions (such as discount rates) and demographic assumptions (such as life expectancy, retirement age, employee turnover, and the rate of salary increases).

We recognize all actuarial gains and losses (including the impact of a change in discount rate) immediately through equity. A sensitivity analysis to the discount rate is set forth in Note D.19.1. “Provisions for pensions and other benefits” to our consolidated financial statements included at Item 18 of this annual report.

Depending on the key assumptions used, the pension and post-retirement benefit expense could vary within a range of outcomes and have a material effect on reported earnings. A sensitivity analysis to these key assumptions is set forth in Note D.19.1. “Provisions for pensions and other benefits” to our consolidated financial statements included at Item 18 of this annual report.

6/ Deferred taxes

As discussed in Note B.22. “Income tax expense” to our consolidated financial statements included at Item 18 of this annual report, we recognize deferred income taxes on tax loss carry-forwards and on temporary differences between the tax base and carrying amount of assets and liabilities. We calculate our deferred tax assets and liabilities using enacted tax rates applicable for the years during which we estimate that the temporary differences are expected to reverse. We do not recognize deferred tax assets when it is more likely than not that the deferred tax assets will not be realized. The recognition of deferred tax assets is determined on the basis of profit forecasts for each tax group, and of the tax consequences of the strategic opportunities available to Sanofi.

ITEM 5. OPERATING AND FINANCIAL REVIEW AND PROSPECTS

7/ Provisions for risks

Sanofi and its subsidiaries and affiliates may be involved in litigation, arbitration or other legal proceedings. These proceedings typically are related to product liability claims, intellectual property rights, compliance and trade practices, commercial claims, employment and wrongful discharge claims, tax assessment claims, waste disposal and pollution claims, and claims under warranties or indemnification arrangements relating to business divestitures. As discussed in Note B.12. “Provisions for risks” at Item 18 of this annual report, we record a provision where we have a present obligation, whether legal or constructive, as a result of a past event; it is probable that an outflow of resources embodying economic benefits will be required to settle the obligation; and a reliable estimate can be made of the amount of the outflow of resources. For additional details regarding the financial impact of provisions for risks see Notes D.19.3. “Other provisions” and D.22. “Legal and Arbitral Proceedings” to our consolidated financial statements included at Item 18 of this annual report.

8/ Provisions for restructuring costs

Provisions for restructuring costs include early retirement benefits, compensation for early termination of contracts, and rationalization costs relating to restructured sites. Refer to Note D.19.2 to our consolidated financial statements included in Item 18 of this annual report.

Provisions are estimated on the basis of events and circumstances related to present obligations at the end of the reporting period and of past experience, and to the best of management’s knowledge at the date of preparation of the financial statements. The assessment of provisions can involve a series of complex judgments about future events and can rely heavily on estimates and assumptions. Given the inherent uncertainties related to these estimates and assumptions, the actual outflows resulting from the realization of those risks could differ from our estimates.

A.2.1. Net Sales

Consolidated net sales for the year ended December 31, 2019 amounted to € 36,126 million, 4.8% higher than in 2018 . Exchange rate fluctuations had a positive effect of 2.0 percentage points overall, due mainly to favorable trends in the euro exchange rate against the US dollar and Japanese yen. The Argentinean peso had an unfavorable effect of €166 million in 2019, including the effects of applying hyperinflation accounting from July 1, 2018 onwards (see Note A.4. to our consolidated financial statements).

At constant exchange rates (CER), net sales rose by 2.8% , impacted by (i) the acquisition of Bioverativ’s rare blood disorder products and (ii) the divestment of our European generics business in 2018. At constant exchange rates and on a constant structure basis (CER/CS), the growth rate was 3.6% . Strong performances for Dupixent ^®, and for Vaccines across all geographies, combined with growth in Emerging Markets sales, more than offset lower sales of Lantus ^® and Established Prescription Products in mature markets.

Net sales at constant exchange rates and on a constant structure basis	35,438		34,195		+3.6	%


(a)	Elimination of the €456 million of net sales generated from January 1 through September 30, 2018 by Zentiva, our European generics business, divested September 30, 2018.


(b)	Add-back of the €188 million of net sales generated from January 1 through March 7, 2018 by Bioverativ, consolidated from March 8, 2018 onwards.

When we refer to changes in our net sales on a constant structure (CS) basis, that means that we eliminate the effect of changes in structure by restating the net sales for the previous period as follows:


▪	by including sales generated by entities or product rights acquired in the current period for a portion of the previous period equal to the portion of the current period during which we owned them, based on historical sales information we receive from the party from whom we make the acquisition;


▪	similarly, by excluding sales for a portion of the previous period when we have sold an entity or rights to a product in the current period; and


▪	for a change in consolidation method, by recalculating the previous period on the basis of the method used for the current period.

To facilitate analysis and comparisons with prior periods, some figures are given at constant exchange rates and on a constant structure basis (CER/CS).

1/ Net sales by Operating Segment and Global Business Unit

Our net sales comprise the net sales generated by our Pharmaceuticals, Consumer Healthcare and Vaccines segments.

The table below also presents an analysis of our net sales by Global Business Unit (GBU).

(a)	Does not include Emerging Markets net sales.


(b)	Rare Diseases, Multiple Sclerosis, Oncology, Immunology, and Rare Blood Disorders.


(c)	Includes net sales in Emerging Markets of Specialty Care and Primary Care products.


(d)	Emerging Markets: World excluding United States, Canada, Europe (apart from Eurasia: Russia, Ukraine, Georgia, Belarus, Armenia and Turkey), Japan, South Korea, Australia, New Zealand and Puerto Rico.

In 2019, our Primary Care GBU (which combines our Diabetes & Cardiovascular and Established Prescription Products franchises) and our Specialty Care GBU were focused exclusively on mature markets. Sales of Specialty Care and Primary Care products in emerging markets were included within the net sales of our China & Emerging Markets GBU, which during 2019 was focused on the distinctive characteristics and growth potential of emerging markets, especially China.

New Global Business Units

On December 9, 2019, our Chief Executive Officer unveiled his new strategy to boost growth and our potential for innovation. From the first quarter of 2020, Sanofi will be organised into three core Global Business Units to support our strategy (subject to completion of consultation with employee representatives): the Specialty Care GBU (Immunology, Rare Diseases, Rare Blood Disorders, Neurology and Oncology); the Vaccines GBU; and the General Medicines GBU (Diabetes, Cardiovascular and Established Prescription Products). The Consumer Healthcare GBU will become a standalone business unit with integrated manufacturing and R&D functions.

As specified on February 6, 2020, at the occasion of the 2019 fourth-quarter and full-year results presentation, the General Medicines GBU will be created from two existing GBUs, Primary Care and China & Emerging Markets. Each GBU will include its respective Emerging Markets sales contribution . Olivier Charmeil has been appointed to lead the General Medicines GBU. Olivier is one of Sanofi’s most seasoned business leaders. He will draw on his recent experience leading the China & Emerging Markets GBU to engage with customers and markets and




SANOFI / FORM 20-F 2019	63

ITEM 5. OPERATING AND FINANCIAL REVIEW AND PROSPECTS

ensure that our combined Diabetes, Cardiovascular and Established Products business drives growth and delivers for patients around the world. Alongside the GBU reorganization, Sanofi will implement changes in the configuration of its Executive Committee. This leadership committee will now include, in addition to the four GBU Heads, the global Heads of R&D, Industrial Affairs, Finance, Human Resources and Legal, together with the Chief Digital Officer. A leaner configuration will foster agility and speed in decision-making, in line with the fourth priority of the company’s new strategy (“Reinvent How We Work”).

2/ Net sales by Franchise, Geographical Region and Product

The table below sets forth our 2019 and 2018 net sales by franchise, geographical region and product in order to facilitate direct comparisons with our peers. It also provides a reconciliation of sales by GBU for our Pharmaceuticals segment. Net sales for the Specialty Care GBU are obtained by aggregating sales of Specialty Care products in Europe, the United States and the Rest of the World region. Net sales for the General Medicines GBU are obtained by aggregating sales of General Medicines products in Europe, the United States and the Rest of the World region. Net sales for the China & Emerging Markets GBU are obtained by aggregating sales of all our pharmaceutical products in emerging markets.

3/ Net sales - Pharmaceuticals Segment

In 2019 , net sales for the Pharmaceuticals segment were € 25,708 million ( +4.1% on a reported basis, +2.2% at constant exchange rates (CER)). At constant exchange rates and on a constant structure basis, Pharmaceuticals segment net sales were 3.3% higher in 2019 than in 2018 . The year-on-year increase of €1,023 million on a reported basis reflects (i) favorable exchange rate effects of €486 million; (ii) the negative net effect of €268 million of the acquisition of Bioverativ products and the divestment of our European Generics business; and (iii) the following effects at constant exchange rates and on a constant structure basis:


▪	positive performances from the Immunology franchise (+€1,290 million), the Rare Diseases franchise (+€192 million), the Oncology franchise (+€159 million), the Multiple Sclerosis franchise (+€37 million) and the Rare Blood Disorders franchise (+€9 million); and


▪	negative performances from the Diabetes franchise (-€451 million), the Established Prescription Products franchise, which now includes Generics (-€403 million), and the Cardiovascular franchise (-€28 million).

Comments on the performances of our major Pharmaceuticals segment products are provided below.

Specialty Care

Rare Diseases franchise

Net sales for the Rare Diseases franchise amounted to € 3,165 million in 2019 , up 7.0 % on a reported basis and 6.5 % at constant exchange rates (CER), driven by sales in Emerging Markets (+ 24.0 % CER at € 614 million). In the United States, the franchise grew net sales by 4.7 % CER in 2019, to € 1,183 million, while in Europe net sales rose by 1.9 % CER over the same period to € 1,027 million.

Net sales of Myozyme ^® / Lumizyme ^® in Pompe disease rose by 8.3% CER in 2019 to €918 million, boosted by sales growth in Emerging Markets (+26.6% CER at €146 million) and in the United States (+10.6% CER at €331 million). Sales also grew in Europe (+1.9% CER at €382 million). The year-on-year growth reflects the rising number of patients diagnosed with, and treated for, Pompe disease.




SANOFI / FORM 20-F 2019	65

ITEM 5. OPERATING AND FINANCIAL REVIEW AND PROSPECTS

In 2019 , net sales for the Gaucher disease franchise ( Cerezyme ^® and Cerdelga ^® ) reached €914 million, up 7.0% CER, on strong sales of Cerezyme ^® in Emerging Markets (+ 20.4 % CER at € 245 million) and growing adoption of Cerdelga ^® in Europe (+ 43.1 % CER, at € 73 million) and the United States (+ 14.3 % CER at € 118 million). During 2019 , Cerezyme ^® posted net sales of € 708 million (+ 2.7 % CER), while net sales of Cerdelga ^® reached € 206 million (+ 26.4 % CER ).

Fabrazyme ^® recorded net sales growth of 5.3 % CER in 2019 to € 813 million. Sales advanced in all regions due to the increasing number of patients diagnosed with, and treated for, Fabry disease. Growth was particularly strong in Emerging Markets (+ 29.3 % CER at € 98 million), while net sales in the United States rose by 1.6 % CER to € 410 million.

Immunology franchise

Dupixent ^® (developed in collaboration with Regeneron) generated net sales of € 2,074 million in 2019, up 163.2 % on a reported basis and 151.6 % at constant exchange rates. In the United States, the product posted net sales of € 1,669 million in 2019, driven by continued growth in atopic dermatitis (boosted by the approval in mid-March 2019 of an indication for adolescents aged 12 to 17 years) plus a rapid ramp-up in sales for asthma and the launch of the product as a treatment for nasal polyps following FDA approval in June 2019. In Europe, net sales of Dupixent ^® in 2019 were € 200 million, up 165.3 % CER. In the Rest of the World region, Dupixent ^® posted net sales of € 176 million (+ 247.9 % CER), including €131 million in Japan. Dupixent ^® has now been launched in 34 countries as a treatment for atopic dermatitis in adults, with further indications having been approved for atopic dermatitis in adolescents (in 10 countries); for asthma (in 8 countries); and for nasal polyps (in 4 countries).

In 2019, net sales of Kevzara ^® (developed in collaboration with Regeneron) amounted to € 185 million, up 114.5 % CER, fueled by growth in the United States (+ 70.3 % CER at € 115 million) and Europe (+ 207.1 % CER at € 43 million). Those growth figures reflect the adoption of the product, and the expansion of its therapeutic class in mature markets; see also Note C.1, “Alliance Arrangements with Regeneron Pharmaceuticals, Inc.” to our consolidated financial statements.

Multiple Sclerosis franchise

In 2019 , our Multiple Sclerosis franchise generated net sales of € 2,160 million, up 5.4 % on a reported basis and 1.8 % CER, as strong growth in sales of Aubagio ^® offset lower sales of Lemtrada ^® in mature markets.

Aubagio ^® reported net sales of € 1,879 million in 2019, up 10.0 % CER, with strong sales in the United States (+ 10.8 % CER at € 1,351 million) and growth in both Europe (+ 7.0 % CER at € 412 million) and Emerging Markets (+ 20.8 % CER at € 55 million). As of January 1, 2020, Aubagio ^® was excluded from the National Formulary of US third-party payer ESI, which covers roughly 14% of total commercial lives in the US. Contracted access positions for Aubagio ^® remain strong for other national health plans and national pharmacy benefit managers (PBMs).

Net sales of Lemtrada ^® in 2019 amounted to € 281 million, down 31.6 % CER on lower sales in Europe ( -43.7 % CER at € 94 million), the United States ( -24.3 % CER at € 151 million) and the Rest of the World region ( -47.4 % CER at € 11 million). The downtrend in sales is mainly due to tougher competition, and to an update to the Summary of Product Characteristics in the European Union.

Oncology franchise

2019 net sales for the Oncology franchise were € 1,695 million, up 13.5 % on a reported basis and 10.6 % CER, on good performances in both Emerging Markets (+ 16.7 % CER at € 490 million) and the United States (+ 11.3 % CER at € 613 million).

Jevtana ^® posted net sales of € 484 million in 2019 (+ 11.1 % CER), driven by growth in the United States (+ 12.3 % CER at € 212 million), Europe (+ 7.0 % CER at € 168 million) and Japan (+14.8% CER at €66 million).

Net sales of Thymoglobulin ^® increased by 16.5 % CER in 2019 to € 354 million, largely on good performances in the United States (+ 16.0 % CER at € 198 million) and Emerging Markets (+ 30.7 % CER at € 96 million), especially China (+23.1% CER at €48 million). Over the same period, net sales of Eloxatin ^® were 10.4 % higher CER at € 203 million, with growth mainly concentrated in Emerging Markets (+ 19.3 % CER at € 181 million), especially China (+28.0% CER at €152 million).

Libtayo ^® (cemiplimab, developed in collaboration with Regeneron) was approved in the United States in September 2018 for patients with metastatic or locally advanced cutaneous squamous cell carcinoma (CSCC) who are not candidates for surgery or curative radiotherapy. Sales of this product in the United States are consolidated by Regeneron under the terms of our alliance with Regeneron; see Note C.1, “Alliance Arrangements with Regeneron Pharmaceuticals, Inc.” to our consolidated financial statements. In 2019, Libtayo ^® was approved in Brazil at the end of March, and in Canada in April. At the end of June 2019, Libtayo ^® was approved in the European Union for adults with metastatic or locally advanced CSCC who are not candidates for surgery or curative radiotherapy. Outside the United States Libtayo ^® was launched in 7 countries and its sales reached €16 million in 2019.

Rare Blood Disorders franchise

Our Rare Blood Disorders franchise was created in 2018 following two acquisitions. The first was the acquisition of Bioverativ, which added two products to our portfolio: the flagship hemophilia treatments Eloctate ^® and Alprolix ^® . This was followed by the acquisition of Ablynx, enhancing our portfolio with the addition of Cablivi ^® (caplacizumab), which received marketing approval from the European Commission in 2018 and from the FDA in February 2019 in the United States in the treatment of acquired thrombotic thrombocytopenic purpura (aTTP).

Net sales for the Rare Blood Disorders franchise in 2019 reached € 1,152 million, up 28.4 % on a reported basis and up 0.8% at constant exchange rates and on a constant structure basis. Higher sales in the Rest of the World region (+17.2% CER/CS at € 258 million), and good performances from Cablivi ^® in the United States and Europe, offset a decrease in sales of Eloctate ^® in the United States.

Consolidated sales of Eloctate ^® , indicated in the treatment of hemophilia A, were € 684 million in 2019, down 11.6% CER/CS. In the United States, net sales were down 18.6% CER/CS at € 517 million, reflecting ongoing competitive pressure. In the Rest of the World region, net sales of Eloctate ^® were up 7.8% CER/CS in 2019 at € 147 million (including €96 million in Japan).




66	SANOFI / FORM 20-F 2019

ITEM 5. OPERATING AND FINANCIAL REVIEW AND PROSPECTS

Net sales of the hemophilia B treatment Alprolix ^® reached € 412 million in 2019, up 12.4% CER/CS. In the United States, the product posted a 6.0% rise in sales CER/CS, to € 300 million. In the Rest of the World region, Alprolix ^® net sales were 32.5% higher CER/CS at € 111 million, reflecting sales growth in Japan and increased sales to Swedish Orphan Biovitrum AB (SOBI): Alprolix ^® is developed and commercialized in collaboration with SOBI, whose sales territories include Europe, Russia, the Middle East and some North African countries.

Cablivi ^® generated net sales of € 56 million in 2019. In the United States, where Cablivi ^® has been on sale since April 2019, net sales reached € 34 million. In Europe, where the product is on sale in Germany, Denmark, Austria, Belgium and the Netherlands, net sales were € 22 million. The product is also on sale in France, where the healthcare authorities have granted by a temporary authorization for use.

General Medicines

Diabetes franchise

Net sales for the Diabetes franchise were € 5,113 million in 2019 , down 6.6 % on a reported basis and 8.2 % CER. This reflects a decline in sales for the franchise in the United States (- 21.5 % CER at € 1,811 million), especially of insulin glargines (Lantus ^® and Toujeo ^® ) as a result of changes to Medicare Part D welfare program cover and the ongoing decline in average net prices for insulin glargines in the United States. However, we expect that reimbursement of our principal Diabetes products by US payers will be largely maintained in 2020. Elsewhere in the world, net sales for the Diabetes franchise rose in Emerging Markets (+ 10.3 % CER at € 1,701 million) but fell in the Rest of the World region (- 17.1 % CER at € 393 million) and in Europe (- 5.0 % CER at € 1,208 million), as good performances from Toujeo ^® only partially offset lower sales of Lantus ^® .

Over 2019 as a whole, net sales of our insulin glargines (Lantus ^® and Toujeo ^® ) were down 11.6% on a reported basis and 13.2% CER at €3,895 million.

Net sales of Lantus ^® in 2019 were down 17.0 % CER at € 3,012 million. In the United States, net sales decreased by 32.5 % CER to € 1,149 million for the reasons explained above. Net sales in Europe were 14.6 % lower CER at € 584 million, due largely to the launch of a biosimilar of Lantus ^® and the switching of patients to Toujeo ^® . In Emerging Markets, sales of Lantus ^® advanced by 9.7 % CER to € 1,061 million.

In 2019 , Toujeo ^® posted net sales of € 883 million (+ 3.2 % CER), driven by strong performances in Emerging Markets (+ 39.2 % CER at € 180 million) and Europe (+ 15.5 % CER at € 334 million). Sales decreased by 20.3 % CER in the United States to € 289 million), mainly as a result of a decrease in the average net selling price.

Net sales of Apidra ^® in 2019 were down 3.6 % CER at € 344 million. Lower sales in the United States (- 41.9 % CER at € 46 million) were partially offset by sales growth in Emerging Markets (+ 22.9 % CER at € 130 million).

Amaryl ^® posted net sales of € 334 million in 2019 , down 2.1 % CER on 2018. In China, the second wave of the nationwide VBP (volume-based procurement) program includes glimepiride in 2020 and Sanofi has opted not to bid with Amaryl ^® . In China, Amaryl ^® sales were €136 million (+3.1% CER) in 2019. Sanofi expects sales of Amaryl ^® in China to decline significantly in 2020 due to the extended VBP program.

Admelog ^® (injectable insulin lispro), launched in 2018 in the United States and also as a biosimilar in some European countries under the name Insulin lispro Sanofi ^® , generated net sales of € 250 million in 2019 , including € 235 million in the United States as a result of its being accepted onto the Managed Medicaid program. However, we expect a contraction in net sales of Admelog ^® in 2020 following a downward adjustment of 44% to the wholesale price in the United States.

Soliqua ^® 100/33 and Suliqua ^® (insulin glargine 100 units/ml and lixisenatide 33 mcg/ml injectable) posted a 60.3% rise in net sales at CER in 2019, to €122 million. Sales grew in all geographies, and reached €87 million in the United States.

Cardiovascular franchise

Net sales for the Cardiovascular franchise in 2019 were € 605 million, down 1.0 % on a reported basis and 4.6 % at constant exchange rates.

Net sales of Praluent ^® (developed in collaboration with Regeneron) decreased by 3.8 % CER to € 258 million, on lower sales in the United States (- 30.5 % CER at € 112 million), impacted by a significant price reduction. The effect was partly offset by sales growth in Europe (+ 24.4 % CER at € 107 million), achieved despite German sales of Praluent ^® being suspended in August 2019 following a ruling by the Düsseldorf Regional Court in the ongoing patent litigation. Under the terms of the restructuring of the collaboration agreement between Regeneron and Sanofi proposed in December 2019, Regeneron is expected to obtain sole US rights to Praluent ^® ; see Note C.1, “Alliance Arrangements with Regeneron Pharmaceuticals, Inc.” to our consolidated financial statements.

Net sales of Multaq ^® amounted to € 347 million in 2019 , a decrease of 5.1 % CER compared with 2018 . The majority of the product's net sales are generated in the United States (€ 295 million, down 5.4 % CER) and Europe (€ 40 million, down 7.0 % CER).

Established Prescription Products

Net sales of Established Prescription Products in 2019 amounted to € 9,559 million, down 7.5 % on a reported basis and 8.3 % CER, mainly reflecting the divestment of Zentiva, our European Generics business, at the end of the third quarter of 2018. At constant exchange rates and on a constant structure basis, net sales for our Established Prescription Products franchise were down 4.1%, reflecting competition from generics of Renvela ^® /Renagel ^® in the United States, lower sales of Lovenox ^® in Europe, and of Plavix ^® in China.

Net sales of Lovenox ^® were € 1,359 million, down 7.4 % CER, mainly as a result of lower sales in Europe (- 18.4 % CER at € 709 million) due to competition from biosimilars in several countries. This decrease was not wholly offset by sales growth in Emerging Markets (+ 13.7 % CER at € 542 million).

In China, Plavix ^® and CoAprovel ^® won a nationwide tender in the Volume Based Procurement (VBP) program in September 2019. In the fourth quarter of 2019, sales of Plavix ^® and of the Aprovel ^® /Avapro ^® family decreased substantially in China due to net price adjustments and inventory reduction in the channel following the nationwide implementation of the VBP program in December. In 2020, we expect net sales of Plavix ^® and the Aprovel ^® /Avapro ^® family to be around 50% lower in China due to the price reductions offered to secure the tender.




SANOFI / FORM 20-F 2019	67

ITEM 5. OPERATING AND FINANCIAL REVIEW AND PROSPECTS

In 2019 , Plavix ^® posted net sales of € 1,334 million, down 8.8 % CER, mainly on lower sales in China (-11.6% CER at €728 million, following the implementation of the VBP program as described above) and Japan (-21.1% CER at €131 million, due to generic competition). Sales of Plavix ^® in the United States and Puerto Rico are handled by BMS under the terms of the Sanofi-BMS alliance; see Note C.2., “Alliance Arrangements with Bristol-Myers Squibb (BMS)”, to our consolidated financial statements.

Net sales of Aprovel ^® /Avapro ^® in 2019 reached € 674 million (+ 2.0 % CER). Sales of the product in China began to decrease (-3.0% CER at €290 million) for the reasons described above, while sales in Japan continued to erode under pressure from generics (-28.6% CER at €21 million). However, the impact was more than offset by higher sales of Aprovel ^® /Avapro ^® in the United States (+150.0% CER at €26 million) and Europe (+ 4.6 % CER at € 113 million).

In 2019 , net sales of Renvela ^® /Renagel ^® amounted to € 311 million, down 26.5 % CER, mainly on generic competition in the United States (- 50.2 % CER at € 133 million). The effect was only partially offset by stronger sales in Emerging Markets (+ 38.8 % CER at € 95 million).

Net sales of Generics in 2019 were € 1,075 million, down 27.9 % CER, mainly as a result of the divestment of Zentiva, our European Generics business, in September 2018. At constant exchange rates and on a constant structure basis, Generics net sales rose by 3.9%, driven by the performance in mature markets (+11.4% CER/CS at €405 million). Emerging Markets sales were stable at €670 million.

4/ Net sales - Consumer Healthcare Segment

In 2019 , net sales of Consumer Healthcare products were € 4,687 million, up 0.6 % on a reported basis but down 0.8 % at constant exchange rates. Lower sales of Nutritionals (- 4.1 % CER at € 657 million) were partially offset by sales growth in Allergy, Cough & Cold (+ 2.2 % CER at € 1,179 million) and Pain (+ 1.3 % CER at € 1,259 million), and more generally by the performance in Emerging Markets. Tighter regulation (especially in Europe), coupled with the ongoing effects of divesting non-strategic brands, impacted growth in our Consumer Healthcare operations during 2019; we expect those factors will continue to have an impact in the first half of 2020.

In September 2019, the FDA and the Canadian healthcare authorities announced publicly that ranitidine-based medicines, including Zantac ^® , might contain low levels of N-nitrosodimethylamine (NDMA), and that manufacturers had been asked to conduct tests. Inconsistencies in the results of preliminary tests on the active ingredient used in the products we sell in the United States and Canada led Sanofi to voluntarily recall Zantac ^® in October 2019. As a result of the recall, net sales of Zantac ^® decreased by 42.5% CER to €78 million in 2019.

Consumer Healthcare net sales in Emerging Markets in 2019 were € 1,652 million, up 4.7 % CER. The main drivers were Digestive (+ 13.7 % CER at € 489 million), especially Essentiale ^® in China (+25.9% CER at €68 million), and Allergy, Cough & Cold (+ 8.0 % CER at € 372 million).

In Europe, Consumer Healthcare net sales were 6.4 % lower in 2019 at € 1,311 million, reflecting the divestment of non-strategic brands and tighter regulation.

Consumer Healthcare net sales in the United States were € 1,086 million in 2019 , down 3.6 % CER. Most of the year-on-year decrease was attributable to Digestive (- 24.1 % CER at € 157 million), reflecting the voluntary recall of Zantac ^® as described above.

In the Rest of the World region, net sales for our Consumer Healthcare operations reached € 638 million in 2019 , a rise of 2.7 % CER, driven by sales in Japan (+6.6% CER at €344 million).

5/ Net sales - Vaccines Segment

In 2019 , the Vaccines segment posted net sales of € 5,731 million, up 12.0 % on a reported basis and 9.3 % CER. The main growth drivers were Polio/Pertussis/Hib vaccines in Emerging Markets (+ 23.4 % CER at € 1,108 million) and the performance of Influenza vaccines (+ 7.3 % CER, at € 1,891 million), especially in Emerging Markets and Europe. In the United States, vaccines sales rose by 1.1 % CER to € 2,733 million, with stronger sales of Adult Booster vaccines and Meningitis/Pneumonia vaccines offsetting lower sales of Polio/Pertussis/Hib vaccines. In Emerging Markets and Europe, Vaccines net sales rose by 24.0 % CER (to € 1,825 million) and 12.1 % CER (to € 817 million) respectively.

2019 net sales of Polio/Pertussis/Hib vaccines reached € 1,946 million, up 9.8 % CER, mainly on a good performance in Emerging Markets (+ 23.4 % CER at € 1,108 million), especially from Pentaxim ^® (+71.4% CER at €516 million) and in China (+64.1% CER at €317 million). Those positive effects were partly offset by lower sales both in the United States (- 9.6 % CER at € 380 million), due to fluctuations in inventories held by our principal customers) and in Japan (-3.5% CER at €118 million). In Europe, sales of the franchise were relatively stable (+1.0% CER) at €299 million, of which €209 million was generated by Hexaxim ^® (+8.2% CER).

Net sales of Influenza vaccines rose by 7.3 % CER to € 1,891 million, driven largely by Emerging Markets (+ 35.0 % CER at € 296 million) and Europe (+ 23.7 % CER at € 218 million), where quadrivalent vaccines performed well and vaccine take-up rates improved. In the United States, sales of influenza vaccines held steady at € 1,289 million: the shipment backlog experienced at the start of the year (due to a delay while the WHO selected the strains) was recovered in the fourth quarter.

In 2019, Meningitis/Pneumonia vaccines posted net sales of € 682 million, up 8.4 % CER. Net sales of Menactra ^® increased in both the United States and Emerging Markets, by 3.4 % CER (to € 507 million) and 29.1 % CER (to € 161 million) respectively.

Net sales of Adult Booster vaccines in 2019 reached € 563 million, up 16.2 % CER, driven by strong performances in Europe (+ 28.7 % at € 166 million) especially from Repevax ^® , and in the United States (+ 11.7 % CER at € 320 million) especially from Adacel ^® /Covaxis ^® .

Net sales of Travel and Other Endemics vaccines in 2019 were up 8.4 % CER at € 539 million, on increased demand for yellow fever vaccine.

In 2019 , net sales in the United States reached € 12,756 million, up 10.5 % on a reported basis and 5.0 % at constant exchange rates, due in part to the acquisition of Bioverativ's products in 2018. At constant exchange rates and on a constant structure basis, US sales reflect solid performances from Dupixent ^® (+ 140.8 % CER at € 1,669 million), Admelog ^® (+ 158.1 % CER at € 235 million) and Aubagio ^® (+ 10.8 % CER at € 1,351 million), which more than offset a decrease in sales of Lantus ^® ( -32.5 % CER at € 1,149 million) and Renvela ^® /Renagel ^® ( -50.2 % CER at € 133 million).

In Emerging Markets , net sales amounted to € 10,914 million, up 7.9 % on a reported basis and 8.7 % CER. All our Pharmaceuticals franchises posted net sales growth in Emerging Markets, as did Vaccines and Consumer Healthcare. The biggest contributors to sales growth in Emerging Markets were Polio/Pertussis/Hib vaccines (+ 23.4 % CER at € 1,108 million), the Diabetes franchise (+ 10.3 % CER at € 1,701 million), and the Rare Diseases franchise (+ 24.0 % CER at € 614 million). In Asia , net sales were € 4,393 million (+ 8.5 % CER), reflecting a solid performance in China (+8.8% CER at €2,704 million) driven by Vaccines and Pharmaceuticals. In Latin America , net sales amounted to € 2,734 million, up 4.7 % on a reported basis and 11.2 % CER. Net sales in Brazil during 2019 were up 1.6% CER at €1,013 million on growth in Vaccines. In the Africa and Middle East region, net sales were € 2,307 million, up 1.7 % CER: good performances from Established Prescription Products (+3.9% CER at €1,017 million) and from the Rare Diseases and Immunology franchises offset lower sales for the Vaccines segment in the region. In Eurasia , net sales reached € 1,312 million (+ 17.2 % CER) on strong growth in Turkey (+30.5% CER at €495 million) and Russia (+9.1% CER at €673 million).

Net sales in Europe decreased by 6.1 % CER in 2019 to € 8,852 million, due largely to the divestment of our European Generics business in 2018. At constant exchange rates and on a constant structure basis, net sales in Europe were down 1.3% year-on-year: a decrease in sales of Lovenox ^® , Lantus ^® and Lemtrada ^® and lower sales in Consumer Healthcare were not wholly offset by good performances from Dupixent ^® and Vaccines.

In the Rest of the World region, net sales rose by 2.8 % CER to € 3,604 million. In Japan, net sales reached €1,908 million (+4.6% CER), boosted by sales of Dupixent ^® , which more than offset a decrease in sales of Plavix ^® , Aprovel ^® and Myslee ^® due to generic competition.

A.2.2. Other income statement items

1/ Other revenues

Other revenues increased by 24.0 % to € 1,505 million in 2019 (versus € 1,214 million in 2018 ). This line item mainly comprises VaxServe sales of non-Sanofi products (€1,273 million, versus €959 million in 2018 , recorded within the Vaccines segment), and revenues associated with the distribution of Eloctate ^® and Alprolix ^® (primarily in Europe) under our agreements with Swedish Orphan Biovitrum AB.

2/ Gross profit

Gross profit for 2019 amounted to € 25,655 million compared with € 24,242 million in 2018 , an increase of 5.8 %. As a percentage of net sales, that represents an improvement on 2018 ( 71.0 % of net sales in 2019 , versus 70.3 % on 2018 ). The year-on-year change includes the impacts of the remeasurement of inventories acquired in the acquisition of Bioverativ (€114 million in 2018).

Gross margin for the Pharmaceuticals segment (the ratio of gross profit to net sales) increased in 2019 to 74.7 % (versus 73.7 % in 2018 ). Positive factors for gross margin in the year included (i) the performance of Dupixent ^® ; (ii) the ending of royalty payments to Bristol-Myers Squibb on sales of Plavix ^® (outside the United States and Puerto Rico) and Avapro ^® ; and (iii) the impact of the divestment of our European Generics business. Those factors outweighed the unfavorable effects of lower average net selling prices for insulin glargines in the United States and a decrease in sales of Established Prescription Products in mature markets.




SANOFI / FORM 20-F 2019	69

ITEM 5. OPERATING AND FINANCIAL REVIEW AND PROSPECTS

Gross margin for the Consumer Healthcare segment decreased in 2019 to 66.3 % (versus 67.0 % in 2018 ), in line with lower sales in the United States, due to the voluntary recall of Zantac ^® .

Gross margin for the Vaccines segment improved in 2019 to 63.3 % (versus 63.0 % in 2018 ), reflecting favorable trends in the product mix.

3/ Research and development expenses

Research and development (R&D) expenses amounted to € 6,018 million in 2019, compared with € 5,894 million in 2018 ), representing 16.7 % of net sales (versus 17.1 % in 2018 ). At constant exchange rates, R&D expenses were stable year-on-year: increased expenditure arising from our acquisitions of Bioverativ and Ablynx, and higher R&D spend in Vaccines, were offset by a reduction in research costs following the restructuring our immuno-oncology agreement with Regeneron.

4/ Selling and general expenses

Selling and general expenses amounted to € 9,883 million ( 27.4 % of net sales), compared with € 9,859 million in 2018 ( 28.6 % of net sales). The year-on-year increase of 0.2 % was attributable mainly to the effect of exchange rates. At constant exchange rates, selling and general expenses were lower year-on-year, reflecting cost control measures in our Pharmaceuticals segment (especially in Primary Care, in mature markets and in support functions) and the divestment of our European Generics business. Those positive factors more than offset an increase in spending in Specialty Care and Vaccines.

5/ Other operating income and expenses

Other operating income amounted to € 825 million in 2019 (versus € 484 million in 2018 ), and other operating expenses to € 1,207 million (versus € 548 million in 2018 ).

Overall, this represented a net expense of € 382 million in 2019 , compared with a net expense of € 64 million in 2018 .



(€ million)	2019		2018		Change
Other operating income	825		484		+341
Other operating expenses	(1,207	)	(548	)	(659	)
Other operating income/(expenses), net	(382	)	(64	)	(318	)

The net negative movement of € 318 million is largely due to (i) an increase in the net expense relating to our pharmaceutical alliance partners (€640 million in 2019 , versus €243 million in 2018 ); the main factor was an increase in the share of profits/losses generated by our alliance with Regeneron under our collaboration agreement (see Note C.1. to our consolidated financial statements), due primarily to higher sales of Dupixent ^® .

The contribution of our alliance with Regeneron to this line is as follows:



(€ million)	2019		2018
Income & Expense related to profit/loss sharing of the Antibodies Alliance	(253	)	177
Additional share of profit paid by Regeneron related to development costs	21		—
Regeneron commercial operating expenses reimbursement	(449	)	(388	)
Total: Antibody Alliance	(681	)	(211	)
Immuno-Oncology Alliance	62		4
Other (mainly Zaltrap ^® )	(14	)	(14	)
Other operating income/(expenses), net, related to Regeneron Alliance	(633	)	(221	)

This line item also includes the favorable impact of top-up pension plan amendments following the application of the Pacte law in France, but also a reduced level of gains on disposals (€296 million in 2019, versus €326 million in 2018).

6/ Amortization of intangible assets

Amortization charged against intangible assets amounted to € 2,146 million in 2019 , compared with € 2,170 million in 2018 .

This € 24 million decrease was due to a reduction in amortization expense generated by intangible assets recognized in connection with the acquisition of various licenses and products (€102 million in 2019, versus €213 million in 2018) and with the acquisitions of Aventis (€197 million in 2019 , versus €256 million in 2018 ) and Genzyme (€727 million in 2019 , versus €760 million in 2018 ) as some products reached the end of their life cycles. Those effects were partly offset by an increase in the amortization charged against intangible assets recognized on the acquisitions of Ablynx (€157 million) and Bioverativ (€488 million).

7/ Impairment of intangible assets

In 2019 , this line item shows net impairment losses of € 3,604 million taken against intangible assets (compared with net impairment losses of € 718 million in 2018 ). The main factor was an impairment loss of €2,803 million against Eloctate ^® franchise assets, reflecting ongoing competitive pressure in the market for hemophilia treatments. It also includes impairment losses of €352 million taken against rights to Zantac ^® following the voluntary recall of this product in the United States and Canada, and €280 million of impairment losses taken against assets associated with internal or collaborative development projects. It does not include the portion of the Eloctate ^® franchise impairment loss allocated to the BIVV001 research project (see above), in accordance with paragraph 104 of IAS 36.




70	SANOFI / FORM 20-F 2019

ITEM 5. OPERATING AND FINANCIAL REVIEW AND PROSPECTS

In 2018 , this line item included impairment losses of (i) €183 million, taken against rights to Lemtrada ^® and (ii) €454 million, taken against assets associated with internal or collaborative development projects (including €92 million relating to the agreement with MyoKardia, and €129 million relating to certain projects arising from the acquisition of Ablynx).

8/ Fair value remeasurement of contingent consideration

Fair value remeasurements of contingent consideration relating to acquisitions represented a net gain of € 238 million in 2019 , versus a net gain of € 117 million in 2018 . These relate mainly to a remeasurement of contingent consideration payable to Bayer as a result of an acquisition made by Genzyme prior to the latter’s acquisition by Sanofi (gain of € 214 million in 2019, versus a gain of € 109 million in 2018) and to remeasurements arising from the dissolution of the Sanofi Pasteur MSD joint venture (net gain of €154 million in 2019, versus a net gain of €30 million in 2018).

9/ Restructuring costs and similar items

Restructuring costs and similar items amounted to a charge of € 1,062 million in 2019 , versus a charge of € 1,480 million in 2018 . In 2019 , restructuring costs mainly comprised termination benefit payments of € 791 million primarily in Europe , the United States and Asia. This line item also includes € 106 million of asset write-downs and accelerated depreciation.

10/ Other gains and losses, and litigation

Other gains and losses, and litigation showed a gain of € 327 million in 2019 (versus a gain of € 502 million in 2018 ), mainly comprising a gain on settlement of litigation.

11/ Operating income

Operating income amounted to € 3,125 million in 2019 , compared with € 4,676 million in 2018 , a year-on-year decrease of 33.2 %, due mainly to impairment losses taken against intangible assets during the period.

12/ Financial income and expenses

Net financial expenses were € 303 million in 2019 , versus € 271 million in 2018 , an increase of € 32 million.

The cost of our net debt (see the definition in “B. Liquidity and Capital Resources” below) decreased to € 172 million in 2019 , compared with €273 million in 2018 . However, this decrease was offset by factors that increased our net financial expenses:


▪	the non-recurrence of gains on disposals of non- current financial assets (zero in 2019, versus €63 million in 2018); and


▪	interest expense on lease liabilities (€39 million in 2019 ), reflecting the first-time application of IFRS 16 from January 1, 2019.

13/ Income before tax and investments accounted for using the equity method

Income before tax and investments accounted for using the equity method amounted to € 2,822 million in 2019 , versus € 4,405 million in 2018 , a decrease of 35.9 %.

14/ Income tax expense

Income tax expense represented € 139 million in 2019 , versus € 481 million in 2018 , giving an effective tax rate based on consolidated net income of 4.9 % in 2019 , compared with 10.9 % in 2018 . Changes in the level of income tax expense are also significantly impacted by the tax effects of the amortization and impairment of intangible assets (€ 1,409 million in 2019 , versus € 692 million in 2018 ) and of restructuring costs (€ 311 million in 2019 , versus € 435 million in 2018 ) as well as the positive tax effects relating to past acquisitions and divestitures .

The effective tax rate on our business net income is a non-GAAP financial measure (see definition under “A.1.5. Segment information - 3. Business Net Income” above). It is calculated on the basis of business operating income, minus net financial expenses and before (i) the share of profit/loss from investments accounted for using the equity method and (ii) net income attributable to non-controlling interests. We believe the presentation of this measure, used by our management, is also useful for investors as it provides a means to analyze the effective tax cost of our current business activities. It should not be seen as a substitute for the effective tax rate based on consolidated net income.

When calculated on business net income, our effective tax rate was 22.0 % in 2019 , compared with 21.6 % in 2018 . The main impacts on this tax rate are the geographical mix of the profits of Sanofi entities.

The table below reconciles our effective tax rate based on consolidated net income to our effective tax rate based on business net income:



(as a percentage)	2019		2018
Effective tax rate based on consolidated net income	4.9	%	10.9	%
Tax effects:
Amortization and impairment of intangible assets	4.3		1.3
Restructuring costs and similar items	5.3		3.4
Other tax effects ^(a)	7.5		6.0
Effective tax rate based on business net income	22.0	%	21.6	%


(a)	In 2019, this line includes the impact of past acquisitions and divestitures; in 2018, it includes the direct and indirect effects of the US tax reform (positive impact of €188 million).




SANOFI / FORM 20-F 2019	71

ITEM 5. OPERATING AND FINANCIAL REVIEW AND PROSPECTS

15/ Share of profit/(loss) from investments accounted for using the equity method

Investments accounted for using the equity method contributed net income of € 255 million in 2019 , versus € 499 million in 2018 . This line item mainly comprises our share of profits from Regeneron (€ 245 million in 2019 , versus € 484 million in 2018 ); the decrease was attributable mainly to lower corporate profits at Regeneron after adjustment to align on our accounting policies.

16/ Net income excluding the exchanged/held-for-exchange Animal Health business

Net income excluding the exchanged/held-for-exchange Animal Health business amounted to € 2,938 million in 2019 , versus € 4,423 million in 2018 .

17/ Net income/(loss) of the exchanged/held-for-exchange Animal Health business

In accordance with IFRS 5, the line item Net income/(loss) of the exchanged/held-for-exchange Animal Health business shows an expense of € 101 million in 2019 (€ 13 million in 2018 ) relating to the final settlement signed in September 2019 with Boehringer Ingelheim.

18/ Net income

Net income amounted to € 2,837 million in 2019 , compared with € 4,410 million in 2018 .

19/ Net income attributable to non-controlling interests

Net income attributable to non-controlling interests was € 31 million in 2019 , versus € 104 million in 2018 . The reduction was mainly due to the ending (effective December 31, 2018) of payments of the share of pre-tax profits due to BMS on sales of Plavix ^® (outside the United States and Puerto Rico) and Avapro ^® /Aprovel ^® under our alliance agreement with BMS (see Note C.2. to our consolidated financial statements) .

20/ Net income attributable to equity holders of Sanofi

Net income attributable to equity holders of Sanofi amounted to € 2,806 million in 2019 , compared with € 4,306 million in 2018 .

Basic earnings per share for 2019 was € 2.24 , versus € 3.45 for 2018 , based on an average number of shares outstanding of 1,249.9 million in 2019 and 1,247.1 million in 2018 . Diluted earnings per share for 2019 was € 2.23 , 35.0 % lower than the 2018 figure of € 3.43 , based on an average number of shares after dilution of 1,257.1 million in 2019 and 1,255.2 million in 2018 .

A.2.3. Segment results

Our business operating income, as defined in Note D.35 (“Segment information”) to our consolidated financial statements, amounted to € 9,758 million in 2019 , compared with € 8,884 million in 2018 , an increase of 9.8 %. That represents 27.0 % of net sales, compared with 25.8 % in 2017.

As indicated in Notes B.26. and D.35. (“Segment information”) to our consolidated financial statements, Sanofi has three operating segments: Pharmaceuticals, Consumer Healthcare and Vaccines.

The table below sets forth our business operating income for the years ended December 31, 2019 and 2018 :



(€ million)	December 31, 2019		December 31, 2018		Change
Pharmaceuticals	8,969		8,488		+5.7	%
Consumer Healthcare	1,556		1,536		+1.3	%
Vaccines	2,195		1,954		+12.3	%

ITEM 5. OPERATING AND FINANCIAL REVIEW AND PROSPECTS

B. Liquidity and Capital Resources

Our operations generate significant positive cash flows. We fund our day-to-day investments (with the exception of significant acquisitions) primarily with operating cash flow, and pay regular dividends on our shares.

“Net debt” is a non-GAAP financial indicator which is reviewed by our management, and which we believe provides useful information to measure our overall liquidity and capital resources. We define “net debt” as (i) the sum total of short term debt, long term debt, and interest rate derivatives and currency derivatives used to manage debt, minus (ii) the sum total of cash and cash equivalents and interest rate derivatives and currency derivatives used to manage cash and cash equivalents. Following the first-time application of IFRS 16 effective from January 1, 2019, net debt does not includes lease liabilities.

As of December 31, 2019 our net debt was € 15,107 million, compared with € 17,628 million as of December 31, 2018 , due mainly to the cash generated by our operating activities. See Note D.17.1. to our consolidated financial statements.

In order to assess our financing risk, we also use the “gearing ratio”, a non-GAAP financial measure (see table in section “B.2. Consolidated Balance Sheet and Debt” below). We define the gearing ratio as the ratio of net debt to total equity. As of December 31, 2019 , our gearing ratio was 25.6 %, compared with 29.9 % as of December 31, 2018 .

Because our net debt and gearing ratio are not standardized measures, they may not be directly comparable with the non-GAAP financial measures of other companies using the same or similar non-GAAP financial measures. Despite the use of non-GAAP measures by management in setting goals and measuring performance, these are non-GAAP measures that have no standardized meaning prescribed by GAAP.

B.1. Consolidated statement of cash flows

Generally, factors that affect our earnings - for example, pricing, volume, costs and exchange rates - flow through to cash from operations. The most significant source of cash from operations is sales of our branded pharmaceutical products and vaccines. Receipts of royalty payments also contribute to cash from operations.

Summarized consolidated statements of cash flows



(€ million)	2019		2018
Net cash provided by/(used in) operating activities	7,744		5,547
Net cash provided by/(used in) investing activities	(1,212	)	(12,866	)
Net cash inflow from the exchange of the Animal Health business for BI’s Consumer Healthcare business	154		(6	)
Net cash provided by/(used in) financing activities	(4,193	)	3,934
Impact of exchange rates on cash and cash equivalents	9		1
Net change in cash and cash equivalents	2,502		(3,390	)

Net cash provided by operating activities amounted to € 7,744 million in 2019 , against € 5,547 million in 2018 .

Operating cash flow before changes in working capital for 2019 amounted to € 8,163 million, compared with € 6,827 million in 2018 . Working capital requirements increased by € 419 million in 2019 , compared with an increase of € 1,280 million in 2018 . The main factors in 2019 were an increase of € 462 million in accounts receivable, and a € 547 million rise in inventories associated with new products (especially Dupixent ^® ).

Net cash used in investing activities totaled € 1,212 million in 2019 , compared with € 12,866 million in 2018 .

Acquisitions of property, plant and equipment and intangible assets amounted to € 1,816 million, versus € 1,977 million in 2018 . There were € 1,323 million of acquisitions of property, plant and equipment (versus € 1,415 million in 2018 ), mostly (€ 851 million) in the Pharmaceuticals segment, primarily in industrial facilities. The Vaccines segment accounted for € 462 million of acquisitions of property, plant and equipment during 2019 . Acquisitions of intangible assets (€ 493 million, versus € 562 million in 2018 ) mainly comprised contractual payments for intangible rights under license and collaboration agreements.

Acquisitions of equity interests in other entities, during 2019 , totaled € 526 million, net of the cash of acquired entities and after including assumed liabilities and commitments. This compares with € 12,994 million in 2018 , when the main acquisitions were Bioverativ (€8,932 million) and Ablynx (€3,639 million).

After-tax proceeds from disposals were € 1,224 million in 2019 , and arose mainly from sales of our equity interest in Alnylam (€706 million) and in MyoKardia (€118 million). In 2018 , after-tax proceeds from disposals amounted to € 2,163 million, mainly arising on the divestment of our European Generics business (€1,598 million), the sale of some Consumer Healthcare products to Cooper-Vemedia (€158 million), and the divestment of equity interests in Impact Therapeutics (€99 million).

Net cash provided by/used in financing activities represented a net cash outflow of € 4,193 million in 2019 , compared with a net inflow of € 3,934 million in 2018 . The 2019 figure includes net debt repayments of € 491 million (versus net external debt finance raised of € 8,722 million in 2018 ); the dividend payout to our shareholders of € 3,834 million (versus € 3,773 million in 2018 ); and the effect of changes in our share capital (repurchases of our own shares, net of capital increases), representing a net inflow of € 153 million in 2019 and a net outflow of € 924 million in 2018 .

The net change in cash and cash equivalents during 2019 was an increase of € 2,502 million, versus a decrease of € 3,390 million in 2018 .

" Free cash flow " for the year ended December 31, 2019 was €6,026 million. This represents an increase on the 2018 figure of €4,054 million, mainly as a result of a rise in our business net income; a reduction in cash outflows on pensions and other employee-related benefits; and a lower level of investment in property, plant and equipment.

Free Cash Flow is a non-GAAP financial indicator which is reviewed by our management, and which we believe provides useful information to measure the net cash generated from the Company’s operations that is available for strategic investments ⁽¹⁾ (net of divestments ⁽¹⁾ ), for debt repayment, and for payments to shareholders. Free Cash Flow is determined from Business Net Income ⁽²⁾ adjusted for depreciation, amortization and impairment, share of undistributed earnings from investments accounted for using the equity method, gains & losses on disposals, net change in provisions including pensions and other post-employment benefits, deferred taxes, share-based payment expense and other non-cash items. It also includes net changes in working capital, capital expenditures and other asset acquisitions ⁽³⁾ net of disposal proceeds ⁽³⁾ , and payments related to restructuring and similar items. Free Cash Flow is not defined by IFRS, and is not a substitute for Net cash provided by operating activities as reported under IFRS. Management recognizes that the term “Free Cash Flow” may be interpreted differently by other companies and under different circumstances. The table below sets forth a reconciliation between Net cash provided by operating activities and Free Cash Flow:



(€ million)	2019		2018
Net cash provided by operating activities	7,744		5,547
Acquisitions of property, plant and equipment and software	(1,405	)	(1,674	)
Acquisitions of intangible assets, equity interests and other non-current financial assets ^(a)	(576	)	(635	)
Proceeds from disposals of property, plant and equipment, intangible assets and other non-current assets, net of tax ^(a)	490		522
Repayments of lease liabilities ^(b)	(267	)	—
Other items	40		294
Free cash flow	6,026		4,054


(a)	Free cash flow includes investments and divestments not exceeding a cap of €500 million per transaction.


(b)	Following first-time application of IFRS 16, cash outflows representing repayments of lease liabilities are included in the free cash flow calculation.


(1)	Amount of the transaction above a cap of €500 million per transaction.


(2)	Non-GAAP financial measure, as defined in "- A.1.5 - Segment Information - 3. Business Net income" above.


(3)	Not exceeding a cap of €500 million per transaction.

B.2. Consolidated balance sheet and debt

Total assets were € 112,736 million as of December 31, 2019 , compared with € 111,408 million as of December 31, 2018 , an increase of € 1,328 million.

Net debt was € 15,107 million as of December 31, 2019 , compared with € 17,628 million as of December 31, 2018 , due mainly to the cash generated by our operating activities. “Net debt” is a non-GAAP financial measure which is reviewed by our management, and which we believe provides useful information to measure our overall liquidity and capital resources. We define “net debt” as (i) the sum total of short term debt, long term debt, and interest rate derivatives and currency derivatives used to manage debt, minus (ii) the sum total of cash and cash equivalents and interest rate derivatives and currency derivatives used to manage cash and cash equivalents.



(€ million)	2019		2018
Long-term debt	20,131		22,007
Short-term debt and current portion of long-term debt	4,554		2,633
Interest rate and currency derivatives used to manage debt	(117	)	(54	)
Total debt	24,568		24,586
Cash and cash equivalents	(9,427	)	(6,925	)
Interest rate and currency derivatives used to manage cash and cash equivalents	(34	)	(33	)
Net debt ^(a)	15,107		17,628
Total equity	59,108		59,035
Gearing ratio	25.6	%	29.9	%


(a)	WIth effect from January 1, 2019, the first-time application of IFRS 16 means that lease liabilities are not included in net debt (see Note A.2.1. to our consolidated financial statements).

To assess our financing risk, we use the “gearing ratio”, a non-GAAP financial measure. This ratio (which we define as the ratio of net debt to total equity) reduced from 29.9% as of December 31, 2018 to 25.6% as of December 31, 2019 . Analyses of debt as of December 31, 2019 and December 31, 2018 , by type, maturity, interest rate and currency, are provided in Note D.17.1. to our consolidated financial statements.

We expect that the future cash flows generated by our operating activities will be sufficient to repay our debt. The financing arrangements in place as of December 31, 2019 at the Sanofi parent company level are not subject to covenants regarding financial ratios and do not contain any clauses linking credit spreads or fees to Sanofi’s credit rating.

We have applied IFRS 16 (Leases) with effect from January 1, 2019 (see Note A.2.1. to our consolidated financial statements). As a result, we have recognised in our balance sheet as of December 31, 2019 (i) a right-of-use asset of € 1,300 million; (ii) a non-current lease liability of € 987 million; and (iii) a current lease liability of € 261 million.

Other key movements in the balance sheet are described below.

Total equity was € 59,108 million as of December 31, 2019 , versus € 59,035 million as of December 31, 2018 . The year-on-year change reflects the following principal factors:


▪	increases: our net income for 2019 (€ 2,837 million) and movements in currency translation differences (€ 751 million, mainly on the US dollar); and


▪	decreases : the dividend payout to our shareholders in respect of the 2018 financial year (€ 3,834 million), and repurchases of our own shares (€ 12 million).

As of December 31, 2019 we held 0.02 million of our own shares, recorded as a deduction from equity and representing 0.002 % of our share capital.

Goodwill and Other intangible assets (€ 61,091 million in total) decreased by € 5,033 million year-on-year, the main factors being:


▪	decreases: am ortization and impairment charged during the period (€ 5,928 million, including the impairment loss taken against Eloctate ^® franchise assets); and


▪	increases: currency translation differences (€826 million).

Investments accounted for using the equity method (€ 3,591 million) increased by € 189 million, mainly due to the recognition of our share of the profits of Regeneron.

Other non-current assets were € 304 million lower at € 2,667 million. The main movement during the year was the divestment of our equity interest in Alnylam and MyoKardia.

Net deferred tax assets amounted to € 3,140 million as of December 31, 2019 , versus € 1,199 million as of December 31, 2018 , an increase of € 1,941 million. This was largely due to the reversal of deferred tax liabilities relating to amortization and impairment of intangible assets, and the recognition of deferred tax assets on (i) restructuring provisions and (ii) provisions for pensions and other post-employment benefits (after taking account of actuarial losses).

Non-current provisions and other non-current liabilities (€ 9,321 million) rose by € 708 million, mainly due to an increase in provisions for pensions and other post-employment benefits.




SANOFI / FORM 20-F 2019	75

ITEM 5. OPERATING AND FINANCIAL REVIEW AND PROSPECTS

Liabilities related to business combinations and to non-controlling interests (€ 800 million) were € 504 million lower year-on-year. The main movements in this line item are fair value remeasurements of contingent consideration payable to Bayer as a result of an acquisition made by Genzyme prior to the latter’s acquisition by Sanofi. The year-on-year decrease also reflects the signature of an agreement to settle the ongoing litigation related to the contingent value rights (CVRs) issued in connection with our acquisition of Genzyme (see Note D.22. to our consolidated financial statements).

B.3. Liquidity

We expect that our existing cash resources and cash from operations will be sufficient to finance our foreseeable working capital requirements. At year-end 2019 , we held cash and cash equivalents amounting to € 9,427 million, substantially all of which were held in euros (see Note D.13. to our consolidated financial statements included at Item 18 of this annual report). As at December 31, 2019 , €456 million of our cash and cash equivalents were held by captive insurance and reinsurance companies in accordance with insurance regulations.

We run the risk of delayed payments or even non-payment by our customers, who consist principally of wholesalers, distributors, pharmacies, hospitals, clinics and government agencies (see “Item 3.D. Risk Factors - 2. Risks Relating to Our Business - We are subject to the risk of non-payment by our customers”). Deteriorating credit and economic conditions and other factors in some countries have resulted in, and may continue to result in an increase in the average length of time taken to collect our accounts receivable in these countries. Should these factors continue, it may require us to re-evaluate the collectability of these receivables in future periods. We carefully monitor sovereign debt issues and economic conditions and evaluate accounts receivable in these countries for potential collection risks. We have been conducting an active recovery policy, adapted to each country and including intense communication with customers, negotiations of payment plans, charging of interest for late payments, and legal action. Over our business as a whole, the amount of trade receivables overdue by more than 12 months (which primarily consists of amounts due from public sector bodies) increased from € 61 million as of December 31, 2018 to € 105 million as of December 31, 2019 (see Note D.10. to our consolidated financial statements), due mainly to changes in the level of accounts receivable in the Middle East region .

In November 2011, Sanofi obtained the necessary corporate authorizations to purchase any or all of the outstanding Contingent Value Rights (“CVR”) and subsequently purchased CVRs in 2011. In 2012 following a tender offer initiated in September 2012 on the basis of the same corporate authorization, Sanofi purchased an additional 40,025,805 CVRs (for a total consideration of approximately $70 million), followed by a further 10,928,075 CVRs (for approximately $9 million) in 2013, 1,879,774 CVRs (for approximately $1 million) in 2014, and none in 2015, 2016, 2017, 2018 and 2019. As of December 31, 2019 , a total of 236,457,284 CVRs were outstanding out of the 291,313,510 issued at the time of the Genzyme acquisition.

At year-end 2019 , we had no commitments for capital expenditures that we consider to be material to our consolidated financial position. Undrawn confirmed credit facilities amounted to a total of € 8,000 million at December 31, 2019 . For a discussion of our treasury policies, see “Item 11. Quantitative and Qualitative Disclosures about Market Risk.”

We expect that cash from our operations will be sufficient to repay our debt. For a discussion of our liquidity risks, see “Item 11. Quantitative and Qualitative Disclosures about Market Risk.”

(d)	These comprise irrevocable commitments to suppliers of (i) property, plant and equipment, net of down payments (see Note D.3. to our consolidated financial statements included at Item 18 of this annual report) and (ii) goods and services.


(e)	This line includes all potential milestone payments on projects regarded as reasonably possible, i.e., on projects in the development phase.


(f)	See Note D.18. to our consolidated financial statements included at Item 18 of this annual report.


(g)	See Note D.19.1. to our consolidated financial statements included at Item 18 of this annual report. The table above does not include the ongoing annual employer’s contributions to plan assets, estimated at €46 million in 2019 .

We may have payments due to our current or former research and development partners under collaboration agreements. These agreements typically cover multiple products, and give us the option to participate in development on a product-by-product basis. When we exercise our option with respect to a product, we pay our collaboration partner a fee and receive intellectual property rights to the product in exchange. We are also generally required to fund some or all of the development costs for the products that we select, and to make payments to our partners when those products reach development milestones.

We have entered into collaboration agreements under which we have rights to acquire products or technology from third parties through the acquisition of shares, loans, license agreements, joint development, co-marketing and other contractual arrangements. In addition to upfront payments on signature of the agreement, our contracts frequently require us to make payments contingent upon the completion of development milestones by our alliance partner or upon the granting of approvals or licenses.

Because of the uncertain nature of development work, it is impossible to predict (i) whether Sanofi will exercise further options for products, or (ii) whether the expected milestones will be achieved, or (iii) the number of compounds that will reach the relevant milestones. It is therefore impossible to estimate the maximum aggregate amount that Sanofi will actually pay in the future under existing collaboration agreements.

Given the nature of its business, it is highly unlikely that Sanofi will exercise all options for all products or that all milestones will be achieved.

The main collaboration agreements relating to development projects are described in Note D.21.1. to our consolidated financial statements included at Item 18 of this annual report. Milestone payments relating to development projects under these agreements included in the table above exclude projects still in the research phase (€ 6.7 billion in 2019 , € 6.8 billion in 2018 and € 7.2 billion in 2017 ) and payments contingent upon the attainment of sales targets once a product is on the market (€ 10.6 billion in 2019 , € 9.9 billion in 2018 , € 10.1 billion in 2017 ).

ITEM 6. DIRECTORS, SENIOR MANAGEMENT AND EMPLOYEES

Item 6. Directors, Senior Management and Employees

A. Directors and Senior Management

Since January 1, 2007, Sanofi has separated the offices of Chairman and Chief Executive Officer. Annual evaluations conducted since that date have indicated that this governance structure is appropriate to Sanofi’s current configuration. This arrangement was maintained with the appointment of Serge Weinberg to the office of Chairman firstly on May 17, 2010, then on May 6, 2011, again on May 4, 2015, and finally on April 30, 2019. The Board of Directors regards this governance structure as appropriate to the current context in which Sanofi operates and its share ownership structure, and as protecting the rights of all of its stakeholders.

The Chairman organizes and directs the work of the Board, and is responsible for ensuring the proper functioning of the corporate decision-making bodies in compliance with good governance principles. The Chairman coordinates the work of the Board of Directors with that of its Committees. He ensures that the Company’s management bodies function properly, and in particular that the directors are able to fulfil their duties. The Chairman is accountable to the Shareholders’ General Meeting, which he chairs.

In addition to these roles conferred by law, the Chairman:


▪	in coordination with the Chief Executive Officer, liaises between the Board of Directors and the shareholders of the Company;


▪	is kept regula rly informed by the Chief Executive Officer of significant events and situations affecting the affairs of the Company, and may request from the Chief Executive Officer any information useful to the Board of Directors;


▪	may, in close collaboration with the Chief Executive Officer, represent the Company in high-level dealings with governmental bodies and with key partners of the Company and/or of its subsidiaries, both nationally and internationally;


▪	seeks to prevent any conflict of interest and manages any situation that might give rise to a conflict of interest. He also gives rulings, in the name of the Board, on requests to take up external directorships of which he may become aware or that may be submitted to him by a director;


▪	may interview the statutory auditors in preparation for the work of the Board of Directors and the Audit Committee; and


▪	strives to promo te in all circumstances the values and image of the Company.

The Chairman is also required to develop and maintain a proper relationship of trust between the Board and the Chief Executive Officer, so as to ensure that the latter consistently and continuously implements the orientations determined by the Board.

In fulfilling his remit, the Chairman may meet with any individual, including senior executives of the Company, while avoiding any involvement in directing the Company or managing its operations, which are exclusively the responsibility of the Chief Executive Officer.

Finally, the Chairman reports to the Board on the fulfilment of his remit.

The Chairman carries out his duties during the entire period of his term of office, subject to the caveat that a director who is a natural person may not be appointed or reappointed once that director has reached the age of 70.

The Chief Executive Officer manages the Company, and represents it in dealings with third parties within the limit of the corporate purpose. The Chief Executive Officer has the broadest powers to act in all circumstances in the name of the Company, subject to the powers that are attributed by law to the Board of Directors and to the Shareholders’ General Meeting and within the limits set by the Board of Directors.

The Chief Executive Officer must be less than 65 years old.

Limitations on the powers of the Chief Executive Officer set by the Board

With effect from March 6, 2018, the limitations on the powers of the Chief Executive Officer are specified in the Board Charter. Without prejudice to legal provisions regarding authorizations that must be granted by the Board (regulated agreements, guarantees, divestments of equity holdings or real estate, etc.), prior approval from the Board of Directors is required for transactions or decisions resulting in an investment or divestment, or an expenditure or guarantee commitment, made by the Company and its subsidiaries, in excess of:


▪	a cap of €500 million (per tra nsaction) for transactions, decisions or commitments pertaining to a previously approved strategy; and


▪	a cap of €150 million (per tran saction) for transactions, decisions or commitments not pertaining to a previously approved strategy.

When such transactions, decisions or commitments give rise to installment payments to the contracting third party (or parties) that are contingent upon future results or objectives, such as the registration of one or more products, attainment of the caps is calculated by aggregating the various payments due from signature of the contract until (and including) filing of the first application for marketing authorization in the United States or in Europe.

Attainment of the above caps is also assessed after taking into account all commitments to make payments on exercise of a firm or conditional option with immediate or deferred effect, and all guarantees or collateral to be provided to third parties over the duration of such commitments.

The prior approval procedure does not apply to transactions and decisions that result in the signature of agreements that solely involve subsidiaries and the Company itself.

ITEM 6. DIRECTORS, SENIOR MANAGEMENT AND EMPLOYEES

Board of Directors

Each year, the Board of Directors conducts a review to ensure that there is an appropriate balance in its composition and in the composition of its Committees. In particular, the Board seeks to ensure gender balance and a broad diversity of competencies, experiences, nationalities and ages, reflecting our status as a diversified global business. The Board investigates and evaluates not only potential candidates, but also whether existing directors should seek reappointment. Above all, the Board seeks directors who show independence of mind and are competent, dedicated and committed, with compatible and complementary personalities.

As of December 31, 2019 the Board of Directors had 16 members, including two directors representing employees. 43% of the directors were women and 43% were non-French nationals.

The Board works with the Compensation Committee and the Appointments, Governance and CSR Committee to ensure that the Executive Committee operates an inclusion (non-discrimination) and diversity policy, especially as regards gender balance. As of December 31, 2019 , 21% of the 14 Executive Committee members were women, and 71% were non-French nationals.

The Board of Directors is also kept informed, in particular on the occasion of its annual discussion on professional and pay equality policy, on how the inclusion and diversity policy is cascaded down to “Senior Leaders” (the positions in the Company with the highest level of responsibility). In 2019 , there were 2,066 “Senior Leaders” within Sanofi, including Executive Committee members and other executives; of that total, 37.2% were women.

Subject to the powers expressly attributed to the Shareholders’ General Meeting and within the scope of the Company’s corporate purpose, the Board of Directors’ remit covers all issues relating to the proper management of the Company, and through its decisions the Board determines matters falling within its authority.

The rules and operating procedures of our Board of Directors are defined by law, by our Articles of Association, and by our Board charter (an English language version of which is reproduced in full as Exhibit 1.2 to this Annual Report on Form 20-F).

Term of Office

The term of office of directors is four years. Directors are required to seek reappointment by rotation, such that members of the Board are required to seek reappointment on a regular basis in the most equal proportions possible. Exceptionally, the Shareholders’ Ordinary General Meeting may appoint a director to serve for a term of one, two or three years, in order to ensure adequate rotation of Board members. Each director standing down is eligible for reappointment. Should one or more directorships fall vacant as a result of death or resignation, the Board of Directors may make provisional appointments in the period between two Shareholders’ General Meetings, in accordance with applicable laws.

Directors may be removed from office at any time by a Shareholders’ General Meeting.

A natural person cannot be appointed or reappointed as a director once he or she reaches the age of 70. As soon as the number of directors aged over 70 represents more than one-third of the directors in office, the oldest director shall be deemed to have resigned; his or her term of office shall end at the date of the next shareholders’ Ordinary General Meeting.

Independence of Board Members

Under the terms of the AFEP-MEDEF corporate governance code (the AFEP-MEDEF Code), a director is independent when he or she has no relationship of any kind whatsoever with the Company, its group or its senior management that may color his or her judgment. More specifically, a director can only be regarded as independent if he or she:


▪	is not (and has not been during the past five years):


–	an employee or executive officer of the Company;


–	an employee , executive officer or director of an entity consolidated by the Company; or


–	an employee, executive officer or director of the Company’s parent, or of an entity consolidated by that parent (criterion 1);


▪	is not an e xecutive officer of an entity in which (i) the Company directly or indirectly holds a directorship or (ii) an employee of the Company is designated as a director or (iii) an executive officer of the Company (currently, or who has held office within the past five years) holds a directorship (criterion 2);


▪	is not a customer, supplier, investment banker or corporate banker that is material to the Company or its group, or for whom the Company or its group represents a significant proportion of its business (criterion 3);


▪	has no close family ties with a corporate officer of the Company (criterion 4);


▪	has not acted as auditor for the Company over the course of the past five years (criterion 5);


▪	has not been a director of the Company for more than twelve years (criterion 6);


▪	does not receive variable compensation in cash or in the form of shares or any compensation linked to the performance of the Company or its group (criterion 7); or


▪	does not rep resent a shareholder that has a significant or controlling interest in the Company (criterion 8).

The influence of other factors such as the ability to understand challenges and risks, and the courage to express ideas and form a judgment, is also evaluated before it is decided whether a director can be regarded as independent.




SANOFI / FORM 20-F 2019	79

ITEM 6. DIRECTORS, SENIOR MANAGEMENT AND EMPLOYEES

In compliance with our Board Charter and pursuant to the AFEP-MEDEF Code, the Board of Directors’ meeting of March 4, 2020 discussed the independence of the current directors. Of the sixteen directors present on this date, eleven were deemed to be independent directors by reference to the independence criteria used by the Board of Directors pursuant to the AFEP-MEDEF Code: Serge Weinberg, Emmanuel Babeau, Bernard Charlès, Claudie Haigneré, Patrick Kron, Fabienne Lecorvaisier, Melanie Lee, Suet-Fern Lee, Carole Piwnica, Diane Souza and Thomas C. Südhof.

Consequently, the proportion of independent directors is 79%. This compares with the AFEP-MEDEF recommendation of 50% in companies with dispersed ownership and no controlling shareholder (which is the case for Sanofi). In accordance with the recommendations of the AFEP-MEDEF Code, directors representing employees are excluded when calculating the proportion of independent directors.



	Serge Weinberg	Emmanuel Babeau	Bernard Charlès	Claudie Haigneré	Patrick Kron	Fabienne Lecorvaisier	Melanie Lee	Suet-Fern Lee	Carole Piwnica	Diane Souza	Thomas C. Südhof

Criterion 8: not a significant shareholder	Yes	Yes	Yes	Yes	Yes	Yes	Yes	Yes	Yes	Yes	Yes
Deemed independent	Yes	Yes	Yes	Yes	Yes	Yes	Yes	Yes	Yes	Yes	Yes

1/ Serge Weinberg

Failure to fulfil one of the criteria does not automatically disqualify a director from being independent.

The Board’s conclusions on the situation of Serge Weinberg and on the business relationships review are set out below.

When the offices of Chairman of the Board and Chief Executive Officer were temporarily combined on October 29, 2014, the Board of Directors determined that Serge Weinberg - given his role as Chief Executive Officer - could no longer be regarded as independent. When the two offices were separated again in April 2015, the Board of Directors determined that Serge Weinberg could be regarded as independent and could therefore resume the chairmanship of the Appointments and Governance Committee (renamed the Appointments, Governance and CSR Committee in March 2019).

Under Article 8.6 of the AFEP-MEDEF Code, a non-executive officer cannot be regarded as independent if he or she receives variable compensation in cash or shares or any compensation linked to the performance of the Company or group. Serge Weinberg complies with this criterion, in that he receives fixed compensation only, with no entitlement to variable compensation in either cash or shares.

2/ Business Relationships Review

In its examination of the independence of each director, the Board of Directors took into account the various relationships between directors and Sanofi and concluded that no relationships were of a kind that might undermine their independence. The Board of Directors noted that the Company and its subsidiaries had, in the normal course of business, over the past three years, sold products and provided services to, and/or purchased products and received services from, companies in which certain of the Company’s directors who are classified as independent (or their close family members) were senior executives or employees during 2019. In each case, the amounts paid to or received from such companies over the past three years were determined on an arm’s length basis and did not represent amounts that the Board regarded as undermining the independence of the directors in question.

Board Evaluation

Under the terms of the Board Charter, a discussion of the operating procedures of the Board and its committees must be included on the agenda of one Board meeting every year. The Charter also requires a formal evaluation to be performed at least every three years under the direction of the Appointments, Governance and CSR Committee, with assistance from an independent consultant if deemed necessary.

In 2018, a formal evaluation of the Board was conducted under the direction of the Appointments and Governance Committee (renamed the Appointments, Governance and CSR Committee in March 2019), with assistance from the same specialist consultancy firm as retained for the previous formal evaluation.

The results of the 2018 evaluation showed a positive assessment of the way in which the Board and its Committees operate.

ITEM 6. DIRECTORS, SENIOR MANAGEMENT AND EMPLOYEES

In 2019, in response to the areas for progress and vigilance identified in the 2018 evaluation, steps were taken to enhance the quality of the Board’s work, in terms of deeper long-term strategic thinking and detailed review of R&D priorities.

The 2019 evaluation was conducted internally, using a detailed questionnaire sent to directors by the Secretary to the Board. Each director was allowed a few weeks to complete the questionnaire using a secure digital platform. At the end of that period, the responses were analyzed by the Secretary to the Board, and supplemented by one-on-one interviews. The results were then presented to, and discussed by, the Appointments, Governance and CSR Committee. A detailed report approved at that meeting was presented at the Board meeting of March 4, 2020.

The results of the 2019 evaluation highlighted the following points:


▪	the selection process for the new Chief Executive Officer had been conducted satisfactorily;


▪	the directors have observed increased transparency and dialogue since Paul Hudson’s appointment as Chief Executive Officer, which was reflected in the quality of interactions;


▪	the composition of the Board was regarded as balanced, although more expertise in China, CSR and the pharmaceutical industry would be welcome;


▪	the contribution of the committees to the Board’s decision-making process was regarded as satisfactory; and


▪	a majority of the directors would welcome more concise presentations that allow more time for debate, and better prioritization of agenda items at Board meetings.

The areas for progress and vigilance identified by the Board were:


▪	increased amount of time should be allocated to long-term strategic thinking;


▪	greater attention should be paid to issues relating to CSR and human resources policy;


▪	the induction program for new directors should be enhanced; and


▪	work should progress on preparing succession plans for the Chairman of the Board and members of the Executive Committee.

Succession Planning

The remit of the Appointments, Governance and CSR Committee includes preparing for the future of the Company’s executive bodies, in particular through the establishment of a succession plan for executive officers. The Committee has retained a specialist consultancy firm to evaluate and implement the plan.

The plan, which is reviewed at meetings of the Appointments, Governance and CSR Committee, addresses various scenarios:


▪	unplanned v acancy due to prohibition, resignation or death;


▪	forced vacancy due to poor performance, mismanagement or misconduct; and


▪	planned vac ancy due to retirement or expiration of term of office.

Through its work and discussions, the Committee seeks to devise a succession plan that is adaptable to situations arising in the short, medium or long term, but which also builds in diversity - in all its facets - as a key factor.

To fulfill its remit, the Appointments, Governance and CSR Committee:


▪	provides the Board with progress reports, in particular at executive sessions;


▪	co-ordinates with the Compensation Committee. In that regard, having directors that sit on both Committees is a great advantage;


▪	works closely with the Chief Executive Officer to (i) ensure the plan is consistent with the Company’s own practices and market practices, (ii) ensure high-potential internal prospects receive appropriate support and training, and (iii) check there is adequate monitoring of key posts likely to fall vacant;


▪	meets with key executives as needed; and


▪	involves the Chairman and the Chief Executive Officer insofar as each has a key role in planning for his own successor, though without them directing the process.

In fulfilling their remit, Committee members are acutely conscious of confidentiality issues.

Although aware that separating the offices of Chairman and Chief Executive Officer provides continuity of power, the Committee nonetheless assesses the situation of the Chairman as well as that of the executive team.

In 2019, succession planning for the Chairman of the Board was examined in detail due to the expiry of Serge Weinberg's term of office, which was renewed at the Annual General Meeting on April 30, 2019.

With Olivier Brandicourt approaching the age limit of 65 for serving as Chief Executive Officer as stipulated in the Articles of Association, the Committee identified various potential candidates, both internal and external. The short-listed candidates were presented to the Board members at an executive session on April 25, 2019. Olivier Brandicourt's decision to take retirement led the Committee to accelerate the process of finding a candidate with the right profile to succeed, with assistance from external consultants. The decision to appoint Paul Hudson was taken at a Board meeting on June 6, 2019.

Competencies of Board members

The Board of Directors, in liaison with the Appointments, Governance and CSR Committee, must ensure that the composition of the Board is balanced, diverse and fit for purpose.

In assessing its composition, the Board takes account of the corporate strategy and of the new challenges facing the Company, and determines whether the qualities of serving directors are sufficient for the Board to deliver on its remit.

Over the past several years, the Board has adapted its composition in line with its roadmap by:


▪	bringing ad ditional pharmaceutical industry and healthcare sector expertise onto the Board;


▪	further raising the proportion of non-French directors;


▪	increasing the proportion of women on the Board;


▪	developing its competencies in digital; and


▪	maintaining t he level of core competencies, especially in accounting and finance.

The Annual General Meeting of April 28, 2020 will be asked to renew the terms of office of Laurent Attal, Carole Piwnica, Diane Souza and Thomas Südhof.

The four directors put forward for reappointment to the Board have the following competencies:


▪	Laurent Attal: scientific training, pharmaceutical industry experience, senior executive role in international group and international experience;


▪	Carole Piwnica: Board membership in international group, mergers & acquisitions and finance/accounting;


▪	Diane Souza: health insurance experience, mergers & acquisitions, finance/accounting and regulatory; and


▪	Thomas Südhof: scientific training.

The Annual General Meeting will also be asked to ratify the decision taken at the Board meeting of October 30, 2019 to co-opt Paul Hudson as a director, following the resignation of Olivier Brandicourt from his office as a director further to his decision to take retirement on September 1.

The term of office of Claudie Haigneré, which also expires at the next Annual General Meeting, will not be renewed because by the time of that meeting she will have served for 12 years on the Sanofi Board of Directors. Moreover, Suet-Fern Lee has let known her intention to retire and resign from her director's remit before the next annual shareholder's meeting.

The candidates put forward to replace them are:


▪	Rachel Duan, who would bring to the Board acknowledged healthcare sector expertise and a good knowledge of international markets, especially China,


▪	Lise Kingo, who has a great knowledge of the pharmaceutical industry and sustainable development matters and would bring her expertise in these areas to the Board.

Rachel Duan and Lise Kingo would be qualified as independent directors.

ITEM 6. DIRECTORS, SENIOR MANAGEMENT AND EMPLOYEES

Changes in the composition of the Board of Directors

On February 6, 2019, the Board duly noted the resignation of Christian Mulliez and decided, after consulting the Appointments, Governance and CSR Committee, to co-opt Christophe Babule as a new director. Christophe Babule brings accounting and financial expertise to the Board alongside in-depth experience of international markets, especially in the Asia-Pacific region through having served as Chief Financial Officer for L'Oréal in China and Hong Kong.

The table below shows changes in the composition of the Board of Directors during 2018 and 2019, and the changes that will be submitted for approval at the Annual General Meeting of April 28, 2020:



	Annual General Meeting of May 2, 2018	Annual General Meeting of April 30, 2019	Annual General Meeting of April 28, 2020
Expiry of term of office	Robert Castaigne (independent director)	None	Claudie Haigneré
Renewal of term of office	Olivier Brandicourt Christian Mulliez Patrick Kron (independent director)	Serge Weinberg (independent director and Chairman of the Board of Directors) Suet-Fern Lee (independent director)	Laurent Attal Carole Piwnica Diane Souza Thomas Südhof
Proposed new appointments	Emmanuel Babeau (independent director)	None	Rachel Duan (independent director) Lise Kingo (independent director)
Co-opted	None	Christophe Babule ^(a)	Paul Hudson ^(b)
Other	None	None	None


(a)	Director co-opted by the Board of Directors on February 6, 2019 following the resignation of Christian Mulliez as a director.


(b)	Director co-opted by the Board of Directors on October 30, 2019 following the resignation of Olivier Brandicourt as a director.

If the terms of office of Laurent Attal, Carole Piwnica, Diane Souza and Thomas Südhof are renewed, the co-opting of Paul Hudson is ratified and the appointment of Rachel Duan and Lise Kingo is approved, there would be no change in the number of Board members (16). The proportion of independent directors (79%) and female directors (43%), calculated using currently applicable rules, would not change either. The percentage of foreign directors would reach 50%.

As of December 31, 2019 , the members of our Board of Directors collectively held (directly, or via the employee share ownership fund associated with the Group savings scheme) 19,298 of our shares, representing 0.0015% of our share capital.

As of December 31, 2019 , no corporate officer has been the subject of any conviction or court order, or been associated with any bankruptcy or winding-up order. As of this day, there is no potential conflict of interest between any corporate officer and Sanofi.

Under current French legislation, and given that employees own less than 3% of our share capital, the Board does not include a director representing employee shareholders.

Executive Committee

The Executive Committee is chaired by the Chief Executive Officer. The Committee meets at least twice a month.

In accordance with the Board Charter, the Board of Directors – in liaison with the Compensation Committee and the Appointments, Governance and CSR Committee – ensures that the Chief Executive Officer implements a non-discrimination and diversity policy, especially as regards gender balance on the Executive Committee.

The composition of the Executive Committee changed in 2019, with two members (Olivier Brandicourt and Muzammil Mansuri) leaving and one new member (Paul Hudson) joining.

As of December 31, 2019 , the Executive Committee had 14 members. In February 2020, Sanofi announced a leaner configuration of its Executive Committee. The list below shows all 10 permanent members of our Executive Committee as of the date of publication of this Annual Report on Form 20‑F. A Chief Digital Officer will soon be appointed to the Executive Committee.

Paul Hudson

Chief Executive Officer

Date of birth: October 14, 1967

Paul Hudson joined Sanofi as Chief Executive Officer on September 1, 2019.

Previously CEO of Novartis Pharmaceuticals (2016-2019), where he was a member of the Executive Committee, Paul has had an extensive international career in healthcare that spans the US, Japan and Europe.

Prior to Novartis, he worked for AstraZeneca, where he held several increasingly senior positions and most recently carried out the roles of President, AstraZeneca United States and Executive Vice President, North America.

He began his career in sales and marketing roles at GlaxoSmithKline UK and Sanofi-Synthélabo UK.

Paul holds a degree in economics from Manchester Metropolitan University in the UK and last year his alma mater awarded him an honorary Doctor of Business Administration for his achievements in industry. He also holds a diploma in marketing from the Chartered Institute of Marketing, also in the UK.

SANOFI / FORM 20-F 2019	103

ITEM 6. DIRECTORS, SENIOR MANAGEMENT AND EMPLOYEES

B. Compensation

Compensation and other arrangements for corporate officers

Compensation policy for corporate officers

This section describes the compensation policy for corporate officers of Sanofi, as established pursuant to Article L. 225-37-2 of the French Commercial Code. That policy describes all the components of compensation awarded to corporate officers of Sanofi as consideration for holding office, and explains the process by which it is determined, divided, reviewed and implemented.

Our compensation policy for corporate officers has three distinct elements: (i) the compensation policy for directors; (ii) the compensation policy for the Chairman of the Board; and (iii) the compensation policy for the Chief Executive Officer.

Each of those policies is submitted for approval by our shareholders at the Annual General Meeting, in accordance with Article L. 225-37-2 II of the French Commercial Code. The compensation policy approved in any given year applies to any person holding corporate office in that year. Moreover, when a corporate officer is appointed between two Annual General Meetings, their compensation is defined, applying the terms of the compensation policy approved by the most recent Annual General Meeting.

Process for determining the compensation policy for corporate officers

The compensation policy for corporate officers is established by the Board of Directors, acting on the recommendation of the Compensation Committee. The Board of Directors applies the AFEP-MEDEF Code when determining the compensation and benefits awarded to our non-executive and executive officers.

All members of the Compensation Committee are independent directors, and were chosen for their technical competencies and their good understanding of current standards, emerging trends and Sanofi’s practices.

To fulfill their remit, the Committee regularly invites the Executive Vice President – Human Resources and the Head of Compensation and Employee Benefits to attend their meetings, although they absent themselves when the Committee deliberates. Committee members also work with the Chairman and the Secretary to the Board, who have contacts with our principal shareholders ahead of the Annual General Meeting.

In addition, the Chairman of the Committee:


▪	discusses the financial, accounting and tax impacts of the proposed compensation policy with the Chairman of the Audit Committee;


▪	plays an active role at meetings of the Appointments, Governance and CSR Committee and the Strategy Committee (to both of which he belongs), thereby gaining assurance that the proposed performance criteria are consistent and appropriate in light of Sanofi’s strategic ambitions.

The policy is not subject to annual review, although some arrangements for implementing the policy – such as the performance criteria applicable to annual variable compensation, for example – are defined by the Board of Directors on an annual basis.

After consulting the Compensation Committee and as the case may be the other Board Committees, the Board of Directors may temporarily derogate from the approved compensation policy in exceptional circumstances and to the extent that the changes are aligned on the corporate interest and necessary to safeguard the continuity or viability of Sanofi. The components of compensation where it is possible to derogate from the approved policy are (i) fixed compensation and (ii) annual variable compensation, and the change may be either an increase or a decrease in compensation. The circumstances in which such derogation could apply might include (non-exhaustive list) an exceptional acquisition or a major change in strategy.

General principles and objectives

Our compensation policy is based on the following gener al principles:


▪	the p olicy must be simple;


▪	the policy must prioritize long-term performance;


▪	the level of compensation must be competitive, so that we can attract and retain talent;


▪	there mus t be a fair balance between the corporate interest, the challenges of delivering on our strategy, and the expectations of our stakeholders.

The Compensation Committee must ensure that trends in the compensation of corporate officers over the medium term are not uncorrelated with trends in the compensation of all our employees. In terms of annual variable compensation and equity-based compensation, the Compensation Committee aims to achieve convergence between the performance criteria applied to our Senior Leaders and those applied to the Chief Executive Officer.

Our equity-based compensation policy, which aims to align employee and shareholder interests and reinforce loyalty to Sanofi, is a critical tool for our worldwide attractiveness as an employer.

Acting on the recommendation of the Compensation Committee, the Board of Directors determines the performance conditions attached to equity-based compensation for all beneficiaries at Sanofi and its subsidiaries worldwide, thereby furthering the attainment of our objectives. Our equity-based compensation plan rules are made available to our shareholders on the governance page of our website ( www.sanofi.com ) in the same form as that distributed to our employees.




104	SANOFI / FORM 20-F 2019

ITEM 6. DIRECTORS, SENIOR MANAGEMENT AND EMPLOYEES

During 2018 and until June 2019, equity-based compensation awards to senior executives were in the form of performance shares and (for the Chief Executive Officer) stock options. With effect from June 2019, the Chief Executive Officer is only awarded performance shares. Awarding performance shares makes it possible to maintain a comparable level of employee incentivization while reducing the dilutive effect of equity-based compensation plans for existing shareholders. The Board has sought to standardize the terms of equity-based compensation awards within Sanofi, and has listened to feedback from some shareholders and proxy advisors who have concerns about stock options given their dilutive effect and potential unintended consequences.

The Board of Directors makes any grant of performance shares contingent on multiple multi-year performance criteria in order to ensure that our equity-based compensation plans incentivize overall performance. Failure to achieve those criteria over the entire performance measurement period results in a reduction or loss of the initial grant.

In order to align equity-based compensation with our long-term performance, performance is measured over three financial years (the “vesting period”). Awards of performance shares are also contingent on continued employment in the Sanofi group during the vesting period, followed by further stringent lock-up obligations in the case of the Chief Executive Officer.

The terms of prior awards cannot be reset subsequently, for instance with less exacting performance conditions.

Compensation policy for directors

Directors hold office for a four-year term, as specified in our Articles of Association.

The maximum annual amount of overall compensation that can be allocated to the directors was set by the Annual General Meeting of our shareholders on May 10, 2017 at €1,750,000 (the previous amount of €1,500,000 had been changed due to the entry of two directors representing employees to the Board). Given the increasing number of non-French directors on the Board of Directors and in order to allow a revaluation of the variable portion of the compensation, the forthcoming Annual General Meeting will be asked to approve an increase in the maximum annual amount of overall compensation that can be allocated to the directors to €2,000,000, with effect from the 2020 financial year.

The arrangements for allocating the overall annual amount set by the Annual General Meeting between the Directors are determined by the Board of Directors, acting on a recommendation from the Compensation Committee. Directors’ compensation includes (i) a fixed annual fixed amount of €30,000, apportioned on a time basis for directors who assumed or left office during the year and (ii) a variable amount, allocated by the Board according to actual attendance at Board and Committee meetings. As required by the AFEP-MEDEF Code, directors’ compensation is allocated predominantly on a variable basis.

The Board meeting held on March 4, 2020 raised the amount of compensation allocated to Directors per meeting with effect from the 2020 financial year, with the caveat that those arrangements will apply subject to approval of the new maximum annual amount by the forthcoming Annual General Meeting. It is specified that those amounts had not been changed since 2010. The table below shows how the variable amount payable to directors for attendance at Board and committee meetings would be determined.

If the Annual General Meeting decides not to alter the maximum annual amount allocated to the directors, the arrangements for allocating the overall annual amount between them would remain the same as those applicable for 2019, as described in “— Compensation and benefits of all kinds paid during 2019 or awarded in respect of 2019 to directors” below.



	Remuneration per meeting
	Directors resident in France	Directors resident outside France but within Europe	Directors resident outside Europe	Chairman/ Chairwoman
Board of Directors	€5,000	€8,250	€11,000	N/A
Audit Committee	€8,250	€8,250	€8,250	€11,000
Compensation Committee	€5,500	€8,250	€11,000	Determined by reference to place of residence
Appointments, Governance and CSR Committee	€5,500	€8,250	€8,250	Determined by reference to place of residence
Strategy Committee	€5,500	€8,250	€11,000	Determined by reference to place of residence
Scientific Committee	€5,500	€8,250	€11,000	Determined by reference to place of residence

A director who participates by conference call or by video-conference receives a payment equivalent to half the amount received by a director resident in France who attends in person.

As an exception, in certain cases two meetings held on the same day give entitlement to a single payment:


▪	if on the day of a Shareholders’ General Meeting, the Board of Directors meets both before and after the Meeting, only one payment is made for the two Board meetings;


▪	if on the same day a director participates in a meeting of the Compensation Committee and a meeting of the Appointments, Governance and CSR Committee, only the higher of the two payments is made to cover both meetings.




SANOFI / FORM 20-F 2019	105

ITEM 6. DIRECTORS, SENIOR MANAGEMENT AND EMPLOYEES

The introduction of a separate compensation scale depending on whether or not the director is a European resident is intended to take into account the significantly longer travel time required to attend meetings in person.

Directors do not receive any exceptional compensation or equity-based compensation and have no entitlement to a top-up pension plan.

Neither the Chairman of the Board nor the Chief Executive Officer receives any compensation for serving as a director.

Compensation policy for the Chairman of the Board of Directors

The term of office of the Chairman of the Board is the same as that of the other directors (four years), and the Chairman’s term is aligned with his term of office as a director.

The compensation policy for the Chairman of the Board is discussed by the Compensation Committee, which then makes a recommendation to the Board of Directors. The Chairman of the Board is not a member of the Committee, and does not attend meetings where his compensation is discussed.

The compensation of the Chairman of the Board of Directors (where the office of Chairman is separate from that of Chief Executive Officer, as is currently the case) consists solely of fixed compensation and benefits in kind and excludes any variable or exceptional compensation, any awards of stock options or performance shares, and any directors’ attendance fees.

Where the office of Chairman is separate from that of Chief Executive Officer, the Chairman of the Board is not entitled to the Sanofi top-up defined-contribution pension plan.

Nor is he entitled to a termination benefit or a non-compete indemnity.

Executive officers of Sanofi do not receive any compensation for serving as directors. Consequently, the Chairman of the Board does not receive compensation for chairing Board meetings or meetings of the Appointments, Governance and CSR Committee or the Strategy Committee.

Compensation policy for the Chief Executive Officer

General principles

Our Chief Executive Officer is not appointed for a fixed term of office.

The compensation policy for the Chief Executive Officer is established by the Board of Directors, acting on the recommendation of the Compensation Committee. The compensation structure is not subject to annual review and is applicable for as long as it remains unchanged. The arrangements for implementing the policy may vary from year to year; a table showing the changes made to those arrangements in 2019 and 2018 is provided at the end of the present section.

The compensation of the Chief Executive Officer is determined with reference to compensation awarded to the chief executive officers of the principal companies of the following ten leading global pharmaceutical companies: AstraZeneca plc, Bayer AG, Bristol-Myers-Squibb Inc., Eli Lilly and Company Inc., Johnson & Johnson Inc., GlaxoSmithKline plc, Merck Inc., Novartis AG, Pfizer Inc., and Roche Holding Ltd. This panel comprises companies that are comparable to Sanofi. Consistency with market practice is fundamental in order to attract and retain the talents necessary to our success. In 2019, on the basis of the information published as of the date of this Annual Report on Form 20-F, the median fixed compensation of the chief executive officers of the aforementioned ten leading global pharmaceutical companies was in the region of €1,477,000; the median of the annual variable compensation awarded was in the region of €2,224,000; and the median of the long-term compensation awarded (whether equity-based or in cash) represented around 700% of fixed compensation. The practices of the main CAC 40 companies are also looked at.

The payment and award in a given year of variable compensation, including any in respect of the previous year, are contingent on approval of the Chief Executive Officer’s compensation package by our shareholders in an Ordinary General Meeting, on the terms stipulated in Article L. 225-100 of the French Commercial Code.

This applies to the following components of compensation:


▪	annual variable compensation (established on the basis partly of quantitative criteria, and partly of qualitative criteria);


▪	equity-based compensation (subject to fulfillment of performance conditions).

On taking up office

When the Chief Executive Officer is an outside appointment, the Board of Directors may decide, acting on a recommendation from the Compensation Committee, to compensate the appointee for some or all of the benefits he may have forfeited on leaving his previous employer. In such a case, the terms on which the Chief Executive Officer is hired aim to replicate the diversity of what was forfeited, with a comparable level of risk (variable portion, medium-term equity-based or cash compensation).

During the term of office

Compensation structure

Our policy aims at achieving and maintaining a balance in the compensation structure between fixed compensation, benefits in kind, short-term variable cash compensation, and medium-term variable equity-based compensation.

The compensation policy for the Chief Executive Officer is designed to motivate and reward performance by ensuring that a significant portion of compensation is contingent on the attainment of financial, operational and extra-financial criteria that reflect Sanofi’s objectives, and are aligned with the corporate interest and with the creation of shareholder value. Variable cash compensation and equity-based compensation are the two principal levers for action, and are intended to align the interests of the Chief Executive Officer with those of our shareholders and stakeholders.




106	SANOFI / FORM 20-F 2019

ITEM 6. DIRECTORS, SENIOR MANAGEMENT AND EMPLOYEES

During the meeting that follows the Board meeting held to close off the financial statements for the previous year, the Compensation Committee examines the levels of attainment of variable compensation for that year. In advance of that meeting, the Chief Executive Officer presents the Committee with a report containing narrative and quantitative information necessary to measure attainment of the objectives. The members of the Compensation Committee then discuss the information provided and report to the Board on those discussions, giving an evaluation of the Chief Executive Officer’s performance against each of the criteria.

Annual fixed compensation

The amount of fixed compensation is not subject to annual review. It may however be changed, provided that such changes are not material:


▪	on the appointment of a new Chief Executive Officer, to reflect the new appointee’s competencies and/or then current market practice; and


▪	in exceptional circumstances, to take account of changes in (i) the role or responsibilities of the Chief Executive Officer, for example in terms of market conditions or the size of the Sanofi group or (ii) the performance level of Sanofi over a given period.

Annual variable compensation

Annual variable compensation is in a range between 0% and 250% of fixed compensation, with a target of 150%. It is subject to a range of varied and exacting performance criteria, both quantitative and qualitative. The criteria are reviewed regularly in light of the strategic objectives determined by Sanofi. The Board of Directors sets the criteria for each year at the start of that year. For 2020, the criteria are:


▪	40% based on financial indicators published by the Company: net sales, business net income, free cash flow and business operating income (BOI) margin, each accounting for a quarter. The two new indicators, free cash flow and BOI margin, have been chosen because they are in line with the Company's strategic roadmap.


▪	60% based on specific individual objectives. These include an objective linked to corporate social responsibility, underlining the Board’s commitment to long -term value creation. The individual objectives set for variable remuneration for 2020 are described in "- Compensation and benefits of all kinds awarded to corporate officers in respect of 2020" below.

The percentage of variable compensation linked to the attainment of quantitative criteria may be scaled down regardless of actual performance, in order to give greater weight to the attainment of qualitative criteria. This flexibility can only operate to reduce the amount of variable compensation, and cannot compensate for underperformance on quantitative criteria.

The policy does not allow for the possibility of clawing back any annual variable compensation.

In accordance with Article L. 225-100 II. of the French Commercial Code, payment of annual variable compensation in a given year in respect of the previous year is contingent on a favorable shareholder vote at the Annual General Meeting.

Equity-based compensation

The Chief Executive Officer’s equity-based compensation, which since June 2019 can only be in the form of performance shares, may not exceed 250% of his target short-term compensation (fixed plus variable).

The Chief Executive Officer’s equity-based compensation is contingent upon attainment of exacting performance conditions measured over a three-year-period. Such awards are contingent upon both:


▪	internal criteria based upon business net income and free cash flow (FCF); and

▪

an external criterion based upon total shareholder return (TSR) relative to a benchmark panel of twelve of the leading global pharmaceutical companies: AstraZeneca plc, Bayer AG, Bristol-Myers-Squibb Inc., Eli Lilly and Company Inc., Johnson & Johnson Inc., GlaxoSmithKline plc, Merck Inc., Novartis AG, Pfizer Inc., Roche Holding Ltd., Amgen, and Novo Nordisk. The panel has been expanded effective 2020 so that pharmaceutical companies operating in the biotechnology field are better represented.

The valuation of performance shares is calculated at the date of grant, and represents the difference between the quoted market price of the share on the date of grant and the present value of the dividends to be received over the next three years. The parameters used to calculate the valuations are market parameters available in the financial press.

Each award to our Chief Executive Officer takes into account previous awards and his overall compensation.

In any event, the maximum number of shares to be delivered may not be more than the number of performance shares initially awarded.

Any award of equity-based compensation in a given year is contingent on a favorable shareholder vote at the Annual General Meeting.

Share ownership and lock-up obligation of the Chief Executive Officer

The Chief Executive Officer is bound by the same obligations regarding share ownership specified in our Articles of Association and Board Charter as our other corporate officers.

In addition, until he ceases to hold office the Chief Executive Officer is required to retain a quantity of Sanofi shares equivalent to 50% of any gain (net of taxes and social contributions) arising on the vesting of performance shares, calculated as of the date on which those shares vest. Those shares must be retained in registered form until he ceases to hold office.

In compliance with the AFEP-MEDEF Code and our Board Charter, the Chief Executive Officer must undertake to refrain from entering into speculative or hedging transactions.




SANOFI / FORM 20-F 2019	107

ITEM 6. DIRECTORS, SENIOR MANAGEMENT AND EMPLOYEES

Multi-year variable compensation

The Chief Executive Officer does not receive multi-year variable compensation.

Compensation for serving as a director

Executive officers of Sanofi do not receive any compensation for serving as directors. Consequently, the Chief Executive Officer does not receive compensation in his capacity as a director or as a member of the Strategy Committee.

Exceptional compensation

No exceptional compensation can be awarded to the Chief Executive Officer.

On leaving office

The Chief Executive Officer is entitled to a top-up defined-contribution pension plan, a termination benefit, and a non-compete indemnity.

Such arrangements are part of the overall compensation package generally awarded to executive officers; in line with recommendations of the AFEP-MEDEF code, there are very strict rules about how they are implemented. The termination benefit and non-compete indemnity are intended to compensate for the fact that the Chief Executive Officer may be dismissed at any time.

Each of those benefits is taken into account by the Board of Directors when fixing the overall compensation of the Chief Executive Officer.

Pension arrangements

The Chief Executive Officer is entitled to benefits under the top-up defined-contribution pension plan introduced within Sanofi on January 1, 2020. This is a collective plan falling within the scope of Article 82 of the French General Tax Code. It is also offered to members of our Executive Committee and all senior executives whose position is classified within the Sanofi grade scale as “Executive Level 1 or 2”. The Chief Executive Officer's entitlement under this plan may be withdrawn by a decision of the Board of Directors, but not retroactively.

Under the terms of the plan, the Chief Executive Officer receives an annual contribution the amount of which (subject to attainment of a performance condition) may be up to 25% of his reference compensation (annual fixed and variable cash-based compensation only; all other compensation is excluded). The rights accruing under the plan are those that are generated by the capitalization contract taken out with the insurer, and vest even if the Chief Executive Officer does not remain with Sanofi until retirement. The Chief Executive Officer may elect for the rights to be transferable as a survivor's pension.

The performance condition is as follows:


▪	if the le vel of attainment for variable compensation is equal to or greater than the target (i.e. 150% of fixed compensation), 100% of the contribution is paid;


▪	if the level of attainment for variable compensation is less than 100% of fixed compensation, no contribution is paid; and


▪	between t hose two limits, the contribution is calculated on a prorata basis.

Because this performance condition is linked to the attainment of the performance criteria for annual variable compensation (which itself is determined with reference to the strategic objectives of Sanofi), it ensures that no pension contributions could be made in the event that the Chief Executive Officer fails to deliver.

The plan is wholly funded by Sanofi, which pays the full amount of the gross contributions. Because it is treated as equivalent to compensation, the contribution is subject to payroll taxes and employer’s social security charges, and to income tax in the hands of the Chief Executive Officer; all of the above are charged on the basis of the bands, rates and other conditions applicable to compensation, paid and declared on his payslips for the contribution period.

Subject to (i) formal confirmation by the Board of Directors that the performance condition for the previous year has been met and (ii) approval of the Chief Executive Officer's compensation package for that year by the Annual General Meeting of our shareholders, the annual gross contribution will be paid as follows:


▪	50% as a g ross insurance premium to the fund manager; and


▪	50% to the Chief Executive Officer, to indemnify him for the social security and tax charges for which he will become immediately liable.

In accordance with Article 39.5 bis of the French General Tax Code, deferred compensation as defined in section 4 of Article L. 225-37-3 of the French Commercial Code can be offset against corporate profits as a taxable expense up to a limit set at three times the annual social security ceiling per beneficiary.

The pension entitlement is not cumulative with (i) any termination benefit paid in the event of forced departure or (ii) any non-compete indemnity.

Termination arrangements

The termination benefit only becomes payable if the departure of the Chief Executive Officer is forced, i.e. in the event of removal from office or resignation linked to a change in strategy or control of the Company. Compensation for non-renewal of the term of office is irrelevant in the case of the Chief Executive Officer, because this office is held for an indefinite term.

In addition, no termination benefit is payable and the arrangement is deemed to have been rescinded in the following circumstances:


▪	removal from office for gross or serious misconduct ( faute grave ou lourde );


▪	if the Chief Executive Officer elects to leave Sanofi to take up another position;


▪	if the Chief Executive Officer is assigned to another position within Sanofi; or


▪	if the Chief Executive Officer takes his pension.




108	SANOFI / FORM 20-F 2019

ITEM 6. DIRECTORS, SENIOR MANAGEMENT AND EMPLOYEES

Payment of the termination benefit is contingent upon fulfillment of a performance condition, which is deemed to have been met if the attainment rate for the individual variable compensation objectives exceeded 90% of the target; that condition is assessed over the three financial years preceding the Chief Executive Officer leaving office.

The amount of the termination benefit is capped at 24 months of the Chief Executive Officer’s most recent total compensation on the basis of (i) the fixed compensation effective on the date of leaving office and (ii) the last variable compensation received prior to that date subject to fulfilment of the performance condition.

The amount of the termination benefit is reduced by any amount received as consideration for the non-compete undertaking, such that the aggregate amount of those two benefits may never exceed two years of total fixed and variable compensation.

Non-compete undertaking

In the event of his departure from the Company, the Chief Executive Officer undertakes, during the 12 month period following his departure, not to join a competitor of Sanofi as an employee or corporate officer, or to provide services to or cooperate with such a competitor.

In return for this undertaking, he receives an indemnity corresponding to one year’s total compensation, based on his fixed compensation effective on the day he leaves office and on the last individual variable compensation he received prior to that date. This indemnity is payable in 12 monthly installments.

However, the Board of Directors reserves the right to release the Chief Executive Officer from that undertaking for some or all of that 12-month period. In such cases, the non-compete indemnity would not be due for the period of time waived by the Company.

Consequences of the Chief Executive Officer’s departure for equity-based compensation

If the Chief Executive Officer leaves Sanofi for reasons other than resignation or removal from office for gross or serious misconduct (in which case any award of equity-based compensation is forfeited in full), the overall allocation percentage is prorated to reflect the amount of time the Chief Executive Officer remained with Sanofi during the vesting period.

If at any time prior to the expiration of the vesting period of his performance shares the Chief Executive Officer joins a competitor of Sanofi as an employee or corporate officer, or provides services to or cooperates with such a competitor, he irrevocably loses those performance shares regardless of any full or partial discharge by the Board of Directors of the non-compete undertaking relating to his office as Chief Executive Officer.

If the Chief Executive Officer retires at statutory retirement age prior to the expiration of the vesting period of his performance shares, he will still be entitled to the performance shares initially awarded but will continue to be bound by the other terms of the plan (other than the continuing employment condition), including performance conditions.

There is no acceleration clause in the event of a change of control.

Summary of benefits awarded to the Chief Executive Officer on leaving office

The table below presents a summary of the benefits (as described above) that could be claimed by the Chief Executive Officer on leaving office, depending on the terms of his departure. The information provided in this summary is without prejudice to any decisions that may be made by the Board of Directors.



	Voluntary departure / Removal from office for gross or serious misconduct	Forced departure	Retirement
Termination benefit ^(a)	/	24 months of fixed compensation as of the date of leaving office + 24 months of most recent individual variable compensation received ^(d) – Amounts received as non-compete indemnity	/
Non-compete indemnity ^(b)	12 months of fixed compensation as of the date of leaving office + 12 months of most recent individual variable compensation received prior to leaving office	12 months of fixed compensation as of date of leaving office + 12 months of most recent individual variable compensation received prior to leaving office ^(e)	/
Top-up pension ^(c)	/	/	Annual contribution of up to 25% of reference compensation

(a)	The amount of the termination benefit is reduced by any indemnity received as consideration for the non-compete undertaking, such that the aggregate amount of those two benefits may never exceed two years of total fixed and variable compensation.


(b)	The Board of Directors may decide to release the Chief Executive Officer from the non-compete undertaking for some or all of the 12-month period. In that case, the non-compete indemnity would not be due, or would be scaled down proportionately.


(c)	Defined-contribution pension plan, within the scope of Article 82 of the French General Tax Code. Subject to fulfillment of the performance conditions, assessed annually.


(d)	Subject to fulfillment of the performance condition assessed over the three financial years preceding the departure from office, as described above.

(f)	In this case, the Chief Executive Officer remains subject to the terms of the plans, including the performance conditions and the non-compete clause.




SANOFI / FORM 20-F 2019	109

ITEM 6. DIRECTORS, SENIOR MANAGEMENT AND EMPLOYEES

The table below summarizes adjustments made over the last two years to how the compensation policy for the Chief Executive Officer is implemented:



Post 2019 Shareholders' Meeting	Post 2018 Shareholders' Meeting
Structure of compensation policy unchanged, but adjustments made to how the policy is implemented: The Board of Directors may temporarily derogate from the approved compensation policy in exceptional circumstances. ▪ the Chief Executive Officer is only awarded performance shares, and is no longer awarded stock options; ▪ for restricted shares, the comparison is now made with 12 leading global pharmaceutical companies (instead of 10); ▪ the performance condition applicable tot the termination benefit has been modified; ▪ the top-up pension plan arrangements have changed following the entry into force of Order no. of July 3, 2019 on compensation arrangements for corporate officers of listed companies.	Structure of compensation policy unchanged, but adjustments made to how the policy is implemented: ▪ annual variable compensation, with the introduction of a separate CSR-based individual performance criterion; and ▪ equity-based compensation, with the ROA-based performance criterion replaced with one based on FCF ^(a) in future performance share plans (i.e. those awarded in or after 2019).

Compensation and benefits of all kinds paid during 2019 or awarded in respect of 2019 to directors

As required by Article L. 225-37-3 I. of the French Commercial Code, we present below the total compensation and benefits of all kinds paid during 2019 or awarded in respect of 2019 to corporate officers as consideration for holding office. These arrangements will be submitted for approval by our shareholders at our Annual General Meeting, as required by Article L. 225-100 of the French Commercial Code.

Compensation elements and benefits of all kinds paid during 2019 or awarded in respect of 2019 to directors (table n°3 of the AFEP-MEDEF CODE)

The compensation policy for directors (as described above in section "— Compensation policy for directors") defines the fixed amount of compensation, and the principles for allocating the variable portion between directors, up to the limit of the overall amount approved by the Annual General Meeting.

Directors’ compensation includes a fixed annual payment, apportioned on a time basis for directors who assumed or left office during the year; and a variable amount, allocated by the Board according to actual attendance at Board and Committee meetings. As required by the AFEP-MEDEF Code, directors’ compensation is allocated predominantly on a variable basis.

For 2018 and 2019, variable compensation was determined pursuant to the attendance of the Directors according to the following principles:



Amount of attendance fee per meeting
	Directors resident in France	Directors resident outside France but within Europe	Directors resident outside Europe	Chairman/ Chairwoman
Board of Directors	€5,000	€ 7,000	€ 10,000	N/A
Audit Committee	€7,500	€ 7,500	€ 7,500	10,000
Compensation Committee	€ 5,000	€ 7,500	€ 10,000	Determined by reference to the place of residence
Appointments, Governance and CSR Committee	€ 5,000	€ 7,500	€ 7,500	Determined by reference to the place of residence
Strategy Committee	€ 5,000	€ 7,500	€ 10,000	Determined by reference to the place of residence
Scientific Committee	€ 5,000	€ 7,500	€ 10,000	Determined by reference to the place of residence

A director who participates by conference call or by video-conference receives a payment equivalent to half the amount received by a director resident in France who attends in person.




110	SANOFI / FORM 20-F 2019

ITEM 6. DIRECTORS, SENIOR MANAGEMENT AND EMPLOYEES

As an exception, in certain cases two meetings held on the same day give entitlement to a single payment:


▪	if on the day of a Shareholders’ General Meeting, the Board of Directors meets both before and after the meeting, only one payment is made for the two Board meetings;


▪	if on the same day a director participates in a meeting of the Compensation Committee and a meeting of the Appointments, Governance and CSR Committee, only the higher of the two payments is made to cover both meetings.

The table below shows amounts paid in respect of 2019 and 2018 to each member of our Board of Directors, including those whose term of office ended during those years.

Directors’ compensation for 2018, the amount of which was approved at the Board meeting of March 8, 2019, was partially paid in July 2018, with an additional payment made in 2019.

Directors’ compensation for 2019, the amount of which was approved at the Board meeting of March 4, 2020, was partially paid in July 2019, with an additional payment made in 2020.

ITEM 6. DIRECTORS, SENIOR MANAGEMENT AND EMPLOYEES

Compensation and benefits of all kinds paid during 2019 or awarded in respect of 2019 to Serge Weinberg, Chairman of the Board of Directors

Serge Weinberg has held the office of Chairman of the Board of Directors since May 17, 2010. He has never had, and does not currently have, a contract of employment with Sanofi.

The Chairman of the Board also chairs the Appointments, Governance and CSR Committee and the Strategy Committee, and is a member of the Scientific Committee.

The remit of the Chairman of the Board is specified in the Board Charter, which is reproduced in its entirety in Exhibit 1.2. to this Annual Report on Form 20F.

During the course of 2019, the Chairman’s activities included:


▪	chairing all the meetings of the Board of Directors (13 in 2019) and of the Committees of which he is a member (three meetings of the Appointments, Governance and CSR Committee, eight meetings of the Strategy Committee and three meetings of the Scientific Committee), and participating in Committee meetings to which he was invited (Audit Committee and Compensation Committee);


▪	close monitoring of the proper implementation of the decisions taken by the Board;


▪	active involvement in succession planning for Olivier Brandicourt, Chief Executive Officer until August 31, 2019 (further to his decision to take retirement effective September 1, 2019), including interviewing short-listed candidates and welcoming the new Chief Executive Officer;


▪	meetings with directors, including (i) on the appointment of Christophe Babule, to explain to him how the Board operates and answer his questions, (ii) in connection with the evaluation of the Board’s operating procedures, and (iii) on matters relating to the projects presented to the Board;


▪	regular meetings with members of the senior management team;


▪	site visits to Sanofi locations in France or abroad, and meeting the employees;


▪	meetings with biotechs and medtechs in France and abroad;


▪	organizing two strategy seminars, in April and October 2019; and


▪	representing Sanofi at events or official meetings with representatives of the public authorities and other stakeholders, in line with his remit as defined by the Board Charter.

The Chairman also has a role in explaining positions taken by the Board within its sphere of competence, especially in terms of strategy, governance and executive compensation. In furtherance of this role, Serge Weinberg drew on his experience of corporate communication in:


▪	answering letters from investors and shareholders;


▪	holding meetings with certain shareholders and proxy advisors; and


▪	attending a meeting of the Individual Shareholders Committee at Sanofi headquarters in March 2019, discussing what Sanofi had achieved in 2018 and answering questions about the Company’s latest news, future prospects and dividend policy.

Those tasks were carried out after coordination with the Chief Executive Officer, and in close collaboration with our Investor Relations department.

Compensation awarded in respect of the 2019 financial year

On March 8, 2019, acting on a recommendation from the Compensation Committee, the Board of Directors determined the components of Serge Weinberg’s compensation for the 2019 financial year, taking into account the nature of his duties and the level of his involvement in the work of the Board and in broader corporate governance matters.

For the 2019 financial year, his annual fixed compensation was maintained at €700,000.

In line with our compensation policy for the Chairman of the Board, as approved by our shareholders at the Annual General Meeting of April 30, 2019, he did not receive any variable compensation and was not awarded any stock options or performance shares. He received no compensation for serving as a director, and no compensation from any company included in Sanofi’s scope of consolidation within the meaning of Article L. 233-16 of the French Commercial Code.

The amount reported for benefits in kind (€8,040 in 2019) relates to a company car with a chauffeur.

Serge Weinberg is not covered by the Sanofi defined-contribution pension plan.

Fixed and variable compensation

On March 8, 2019, acting on a recommendation from the Compensation Committee, the Board of Directors determined the components of Olivier Brandicourt’s compensation for the 2019 financial year.

In line with our compensation policy for the Chief Executive Officer, as approved by our shareholders at the Annual General Meeting of April 30, 2019, his annual compensation for 2019 comprised (i) fixed annual gross compensation of €1,200,000 (unchanged since he took office) and (ii) variable annual compensation in a range from 0% to 250% of his fixed annual compensation, with a target of 150%, and subject




SANOFI / FORM 20-F 2019	113

ITEM 6. DIRECTORS, SENIOR MANAGEMENT AND EMPLOYEES

to both quantitative and qualitative criteria. The amount of fixed compensation paid in 2019 was apportioned on a time basis for the period from January 1, 2019 through August 31, 2019, the date on which Olivier Brandicourt left office.

Those objectives were 40% based on financial indicators (sales growth one-third, business net income two-thirds), and 60% based on specific individual objectives.

The Board of Directors, acting on recommendations from the Compensation Committee, adjusts the individual performance criteria annually, while always ensuring continuity and consistency from one year to the next.



Individual objectives for 2019	Individual objectives for 2018
▪ operational transformation (15%);	▪ operational transformation (20%);
▪ pipeline of products (12.5%);	▪ pipeline of products (12%);
▪ organization and staff relations (10%);	▪ organization and staff relations (12%);
▪ new products (10%);	▪ new products (10%);
▪ external growth (7.5%);	▪ external growth (6%).
▪ corporate social responsibility (5%)

Qualitative criteria accounted for 30% of the overall variable compensation objectives for 2019 (versus 32% for 2018).

For confidentiality reasons, neither the level of attainment required (target) for the quantitative criteria nor the details of the qualitative criteria can be disclosed; however, they were pre-determined on a precise basis. In evaluating those criteria, the performance of major global pharmaceutical companies is always taken into account.

Acting on a recommendation from the Compensation Committee, the Board of Directors meeting of March 4, 2020 reviewed the attainment of each criterion and sub-criterion. The Board’s conclusions are summarized in the table below.



	Criterion	Type	Weight		Target / Maximum (as% of fixed compensation)	Assessment	Comments	Payout (as% of fixed compensation)

114	SANOFI / FORM 20-F 2019

ITEM 6. DIRECTORS, SENIOR MANAGEMENT AND EMPLOYEES

Acting on a recommendation from the Compensation Committee, the Board of Directors meeting of March 4, 2020 set Olivier Brandicourt’s variable compensation for 2019 at €1,161,000 (amount calculated on a prorata basis from January 1st, 2019 to August 31, 2019), equivalent to 145.12% of his fixed compensation.

Payment of Olivier Brandicourt’s variable compensation in respect of the 2019 financial year is contingent on approval of his compensation package by the shareholders in an Ordinary General Meeting, on the terms stipulated in Article L. 225-100 of the French Commercial Code.

Social welfare and health insurance

Olivier Brandicourt was subject to, benefited from and contributed to the same health cover, and death and disability plans as are applicable to other employees of Sanofi based in France.

Equity-based compensation

Using the authorizations granted by our shareholders via the 19th and 20th resolutions at the Annual General Meeting of April 30, 2019, and acting on the recommendations of the Compensation Committee, the Board of Directors meeting of April 30, 2019 decided to award Olivier Brandicourt 220,000 stock subscription options and 50,000 performance shares in respect of the 2019 financial year. Using the Black & Scholes model, the valuation of those awards as of April 30, 2019 was equivalent to 3.5 times his fixed compensation.

In line with the compensation policy for the Chief Executive Officer, which stipulates that he retains his rights on retirement (as do all other beneficiaries of Sanofi’s outstanding performance share plans), the Board meeting of July 26, 2019 confirmed that Olivier Brandicourt would retain his rights under those stock option plans and performance share plans that have not yet vested. He continues to be bound by the terms of the plans (including the performance conditions and non-compete clause).

The entire amount of these awards is contingent upon both internal criteria based upon business net income and free cash flow (FCF), and upon an external criterion based on total shareholder return (TSR) relative to a benchmark panel of ten of the leading global pharmaceutical companies (plus Sanofi): AstraZeneca, Bristol-Myers Squibb, Eli Lilly, GlaxoSmithKline, Johnson & Johnson, Merck, Novartis, Pfizer, Roche and Bayer.

To align equity-based compensation on our medium-term performance, a three-year period (2019-2021) is used to measure performance.

The above criteria were selected because they align medium-term equity-based compensation on the strategy adopted by Sanofi.

The arrangements relating to these awards are as follows:

▪

The performance criterion based on business net income accounts for 50% of the award. That criterion corresponds to the ratio, at constant exchange rates, of actual business net income to budgeted business net income. It represents the average actual-to-budget ratio attained over the entire period. Budgeted business net income is derived from the budget as approved by the Board of Directors at the beginning of each financial year. The business net income objective may not be lower than the bottom end of the full-year guidance range publicly announced by Sanofi at the beginning of each year. If the ratio is less than 95%, the corresponding options or performance shares are forfeited.



Business net income actual-to-budget attainment level (“R”)	Business net income allocation rate
If R is less than 95%	0	%
If R is 95%	50	%
If R is > 95% but < 98%	(50 + [(R - 95) x 16])%
If R is ≥98% but ≤ 105%	R %
If R is > 105% but < 110%	(105 + [(R - 105) x 3])%
If R is ≥ 110%	120	%


▪	The FCF criterion accounts for 30% of the award. This criterion has replaced the criterion based on return on assets (ROA) used for awards prior to 2019, because an FCF criterion is (i) more transparent within and outside Sanofi; (ii) easier to cascade down to lower executive grades; and (iii) more closely aligned with Sanofi’s current objectives.

It represents the average actual-to-budget FCF ratio attained over the entire period. The award is based on a target FCF, below which some or all of the options or performance shares are forfeited.



FCF actual-to-budget attainment level (“F”)	FCF allocation rate
If F is ≤ 40%	0%
If F is > 40% but < 80%	[(F - 40) x 1.625]%
If F is 80%	65	%
If F is > 80% but < 100%	[(65 + [F - 80) x 1.75])%
If F is 100%	100	%
If F is > 100% but < 120%	F%
If F is ≥ 120%	120	%

▪

The TSR criterion accounts for 20% of the award. Total shareholder return (TSR) reflects both the appreciation in the value of our shares (the increase in the share price) and the value distributed to our shareholders (dividends), i.e. the two sources of return on investment in Sanofi shares. Our TSR is compared with the benchmark panel of ten companies listed above. The number of options exercisable and performance shares vesting depends upon our position relative to the TSR for the other companies in the panel. Below the median, the corresponding options or performance shares are forfeited.




SANOFI / FORM 20-F 2019	115

ITEM 6. DIRECTORS, SENIOR MANAGEMENT AND EMPLOYEES

The median is the performance of the company ranked sixth. The upper bound is the arithmetical average of the performances of the panel companies ranked first and second. The intermediate level is equal to: median + [(upper bound – median)÷2].


▪	if Sa nofi’s TSR is below the median, the TSR allocation will be 0%;


▪	if Sanofi’s TSR is equal to the median, the TSR allocation will be 50%;


▪	if Sanofi’s TSR is equal to the intermediate level, the TSR allocation will be 100%;


▪	if Sanofi’s TSR is ≥ the upper bound, the TSR allocation will be 150%; and


▪	if Sanofi ’s TSR is above the median but below the upper bound, the TSR allocation will be calculated using linear interpolation.

In addition to the three criteria described above, in the case of stock options there is an implicit condition in the form of the exercise price.

Olivier Brandicourt was under an obligation to retain, until he ceased to hold office, a quantity of Sanofi shares equivalent to (i) 50% of any gain (net of taxes and social contributions) arising on the exercise of stock options and (ii) 50% of any gain (net of taxes and social contributions) arising on the vesting of his performance shares, calculated as of the date on which those shares vest. That obligation lapsed on August 31, 2019, the date on which Olivier Brandicourt left office.

In compliance with the AFEP-MEDEF Code and our Board Charter, Olivier Brandicourt undertook to refrain from entering into speculative or hedging transactions, and so far as the Company is aware no hedging instruments have been contracted.

For confidentiality reasons, the amount of the quantitative measures for the internal criteria cannot be disclosed. However, they were determined on a precise basis, and the level of attainment for the internal criteria will be disclosed at the end of the performance measurement period.

In line with our commitment to transparency, we disclose below the attainment level determined by the Board of Directors for performance conditions (and the corresponding allocation rate) applicable to equity-based compensation plans awarded to the Chief Executive Officer and other members of the Executive Committee. The Board believes that disclosing the level of attainment allows our shareholders to better understand the demanding nature of the performance conditions.

The attainment levels and allocation rates for the most recent equity-based compensation plans are as follows:



	Attainment level			Allocation rate
	Business net income	ROA	TSR

Pension rights

Olivier Brandicourt was covered by the Sanofi top-up defined-benefit pension plan, which fell within the scope of Article L. 137-11 of the French Social Security Code. The plan covered all employees of Sanofi and its French subsidiaries who met the eligibility criteria specified in the plan rules. The Annual General Meeting of our shareholders held on May 4, 2015 approved the section on the pension benefit contained in the auditors’ special report on related-party agreements.

In compliance with the Order of July 3, 2019 that transposed European Directive 2014/50/EU of April 16, 2014 into French law, that plan has been closed, thereby freezing as of December 31, 2019 the past non vested rights of some potential beneficiaries.

Because Olivier Brandicourt pursued his career in different countries and in different groups, he has not continuously paid into the French compulsory industry schemes. Consequently, he was awarded a deemed ten years of service on taking up office at Sanofi.

The Board of Directors, acting on a recommendation from the Compensation Committee, decided at its meeting of February 7, 2017 to apply a performance condition to the vesting of new contingent rights arising under Olivier Brandicourt’s top-up pension plan with effect from January 1, 2017. This alteration in pension arrangements was approved at the Annual General Meeting of our shareholders held on May 10, 2017.

That performance condition was applied on the following basis:


▪	if the leve l of attainment for variable compensation was equal to or greater than the target (i.e. 150% of fixed compensation), 100% of the contingent top-up pension rights granted, corresponding to an uplift of 1.5% in the annual reference compensation used to calculate the annuity payable under the plan;


▪	if the level of attainment for variable compensation was less than 100% of fixed compensation, no top-up pension rights granted for the year in question; and


▪	between th ose two limits, rights were calculated on a prorata basis.

At a meeting on March 4, 2020, our Board of Directors ascertained whether the performance condition had been met, noting that the level of attainment for Olivier Brandicourt’s variable compensation for the 2019 financial year was 96.75%, i.e. 145.12% of his fixed compensation. Taking into account the award of a deemed ten years of service, Olivier Brandicourt had therefore accumulated 14.42 years of service as of August 31, 2019. The reference compensation being limited to 60 times the French social security ceiling (i.e. €2,431,440 in 2019 ⁽¹⁾ , based on a ceiling of €40,524), the amount of his top-up pension is set at €524,766 per year, i.e. 21.5825% of the ceiling. This amount corresponds, for 2019, to an uplift of 0.9675% (capped at 1.50%) of the annual reference compensation.

Because the performance condition for the vesting of his contingent pension rights is linked to the level for his variable compensation in respect of the 2019 financial year, payment of that amount is contingent on approval of his compensation package by our shareholders in an Ordinary General Meeting, on the terms stipulated in Article L. 225-100 of the French Commercial Code.

Olivier Brandicourt took his pension rights at the full rate, and has been officially notified by the Caisse Nationale d’Assurance Vieillesse that he has been granted a personal pension with effect from September 1, 2019. Olivier Brandicourt could then take his rights under the Sanofi top-up defined-benefit pension plan. Based on the information received, the total amount of the annuities paid under those pension plans does not exceed the cap of 52% of reference compensation.

No payment of termination benefit or non-compete indemnity

In line with the compensation policy for the Chief Executive Officer, because Olivier Brandicourt’s pension rights have been paid he was not awarded any termination benefit or non-compete indemnity.


(1)	The amount due for 2019 has been apportioned on a prorata time basis, for the period from January 1, 2019 through August 31, 2019.

Compensation for taking office – Phantom stock units

Having waived all equity-based compensation not yet vested on leaving his previous employer, Paul Hudson was awarded a medium-term incentive plan under which he could be paid a cash bonus subject to continuous presence and performance conditions. Under the terms of the plan, which compensates for around 50% of the incentive plans that Paul Hudson has waived, is awarded phantom stock units, vesting of which is contingent on (i) his continuous presence and (ii) attainment of performance conditions, with those conditions to be measured for half of the award (i.e. 25,000 phantom stock units) as of March 30, 2021 and for the other half of the award (25,000 phantom stock units) as of March 30, 2022.

On expiry of the vesting periods mentioned below, the phantom stock units will vest, entitling Paul Hudson to a cash bonus equal to the value of Sanofi shares, computed as the average of the opening quoted market prices of Sanofi shares on Euronext Paris for the 20 trading days preceding each vesting date.

The phantom stock units are subject to the following performance conditions:


▪	attainment level for business net income, counting towards 50% of the award;


▪	attainment level for free cash flow (FCF), counting towards 30% of the award; and


▪	a performance criterion based on total shareholder return (TSR) as compared with a panel of our peers over each vesting period, counting towards 20% of the award. In addition to Sanofi, the panel consists of: AstraZeneca plc, Bayer AG, Bristol-Myers-Squibb Inc., Eli Lilly and Company Inc., Johnson & Johnson Inc., GlaxoSmithKline plc, Merck Inc., Novartis AG, Pfizer Inc. and Roche Holding Ltd.




SANOFI / FORM 20-F 2019	119

ITEM 6. DIRECTORS, SENIOR MANAGEMENT AND EMPLOYEES

The reference periods for assessing the performance conditions relating to business net income and FCF are:


▪	January 1, 2 020 through December 31 2020, for the 25,000 phantom stock units with a vesting period ending March 30, 2021; and


▪	January 1, 2020 through December 31 2021, for the 25,000 phantom stock units with a vesting period ending March 30, 2022.

The reference periods for assessing the performance conditions relating to TSR are:


▪	the 2020 financial year versus 2019 financial year f or the 25,000 phantom stock units with a vesting period ending March 30, 2021; and


▪	the 2021 financial year versus 2019 financial year f or the 25,000 phantom stock units with a vesting period ending March 30, 2022.

The global allocation rate is calculated using the rules set forth below:

(i) Attainment level for business net income

This performance criterion corresponds to the average actual-to-budget ratio of business net income attained over the entire vesting period. Budgeted business net income will be different from one financial year to the next, and will be approved by the Board of Directors at the beginning of each financial year.

For each financial year within the vesting period, a percentage will be calculated (at constant exchange rates) representing the ratio of actual business net income to budgeted business net income (BNI). That ratio is referred to as the “annual actual-to-budget BNI attainment level”.

At the end of the vesting period, the arithmetical average of the annual actual-to-budget BNI attainment levels for each financial year in that period (the actual-to-budget BNI attainment level, or “B”) will be calculated, and the Board will determine the business net income allocation rate corresponding to that attainment level as indicated below:



BNI achievement rate ("R")	Business net income allocation
If R is less than 95%	0	%
If R is 95%	50	%
If R is > 95% but < 98%	(50 + [(R - 95) x 16]) %
If R is ≥ 98% but ≤ 105%	R%
If R is > 105% but < 110%	(105 + [(R - 105) x 3]) %
If R is ≥ 110%	120	%

(ii) Attainment level for free cash flow (FCF)

This performance criterion corresponds to the average actual-to-budget ratio of FCF attained over the entire vesting period.

Budgeted FCF will be different from one financial year to the next, and will be approved by the Board of Directors at the beginning of each financial year.

For each financial year within the vesting period, a percentage will be calculated (at constant exchange rates) representing the ratio of actual FCF to budgeted FCF. That ratio is referred to as the annual actual-to-budget FCF attainment level. At the end of the vesting period, the arithmetical average of the annual actual-to-budget FCF attainment levels for each financial year in that period (the actual-to-budget FCF attainment level, or “F”) will be calculated, and the Board will determine the business net income allocation rate corresponding to that attainment level as indicated below:



FCF actual-to-budget attainment level ("F")	FCF allocation rate
If F is less than 40%	0	%
If F is > 40% but < 80%	[(F - 40) x 1,625] %
If F is 80%	65%
If F is > 80% but < 100%	(65+ [(F - 80) x1,75]) %
If F is 100%	100%
If F is > 100% but < 120%	F%
If F is ≥ 120%	120	%

(iii) Attainment level for TSR

For the vesting period, the total shareholder return (TSR) performance condition corresponds to the increase in the trading price of Sanofi shares plus dividends per share.

The TSR obtained will be compared with that of each of the companies in the panel of peers listed above, and Sanofi will be ranked against those companies. The TSR allocation rate will be assessed on the basis of Sanofi’s ranking within the panel, as described below:




120	SANOFI / FORM 20-F 2019

ITEM 6. DIRECTORS, SENIOR MANAGEMENT AND EMPLOYEES

TSR allocation rate calculation:


▪	if Sanofi’s TSR is below M, the TSR allocation rate will be 0% - M being the median (i.e. performance of the company ranked six);


▪	if Sanofi’s TSR is M, the TSR allocation rate will be 50%;


▪	if Sanofi’s TSR is equal to the intermediate level, the TSR allocation rate will be 100% - The Intermediate level equals to M + ((H-M)/2);


▪	if Sanofi’s TSR is ≥ H, the TSR allocation rate will be 150% - H being the highest position, i.e. the arithmetic average of the performance of companies in the panel ranked 1st and 2nd; and


▪	if Sanofi’s TSR i s above M but below H, the TSR allocation rate will be calculated using linear interpolation.

The number of phantom stock units actually paid depends on the overall allocation rate, which for each vesting period is the weighted average of the business net income allocation rate (50%), the FCF allocation rate (30%) and the TSR allocation rate for the vesting period (20%).

Fixed and variable compensation

On June 6, 2019, acting on a recommendation from the Compensation Committee, the Board of Directors determined the components of Paul Hudson’s compensation for the 2019 financial year, in line with the compensation policy for the Chief Executive Officer.

His annual compensation for 2019 comprises:


▪	gross fixed compensation of €433,333, after apportionment of his €1,300,000 gross annual fixed compensation on a pro rata time basis over the period from September 1 through December 31, 2019; and

▪

variable annual compensation set at 150% of his annual fixed compensation, also apportioned on a pro rata time basis (i.e. a gross amount of €650,000); given that he was appointed towards the end of the financial year, his variable compensation for 2019 was set at the target level. It is reminded that payment of Paul Hudson’s variable compensation in respect of the 2019 financial year is subject to approval of the compensation package of the Chief Executive Officer by our shareholders in an Ordinary General Meeting, on the terms stipulated in Article L. 225-100 II of the French Commercial Code.

Social welfare and health insurance

Paul Hudson is subject to, benefits from and contributes to the same health cover, and death and disability plans as are applicable to other employees of Sanofi based in France. He also benefits from an unemployment insurance scheme.

Benefits in kind

The benefits in kind received by Paul Hudson in 2019 were valued at €77,400, and correspond to accommodation costs.

Equity-based compensation

Paul Hudson was not awarded any performance shares in 2019.

Pay ratio between compensation of Executive Officers and average/median compensation of Sanofi employees - Changes in compensation of executive officers and employees relative to the performance of Sanofi

This information is disclosed in accordance with Article L. 225-37-3, paragraph 6 of the French Commercial Code following the enactment of the “Pacte” law.

Explanations on calculation methods and on year-on-year changes in the Executive Officers pay ratio:


▪	The scope includes Sanofi SA (the parent company) and all of its direct and indirect subsidiaries located in France, and hence covers more than 80% of total payroll in France.


▪	The employee compensation used in the calculation is the full time equivalent (FTE) compensation of permanent employees with at least two years of uninterrupted employment.


▪	Compensation includes fixed compensation awarded during the reference year, and variable compensation related to the previous year and paid during the reference year.

▪

Long term variable compensation: performance shares and stock options awarded during each reference year are valued at the date of grant in accordance with IFRS Rules. These awards are subject to a continuing employment condition (three years minimum) and to performance conditions. Consequently, the valuation at the date of grant is not necessarily indicative of the value of stock options and performance shares at the end of the vesting period, especially if the performance conditions are not met.

▪

For plans that have expired since 2015, attainment levels were close to 81% for the Chief Executive Officer (73% for performance shares and stock options that vested under the 2013 plan) and close to 100% for the employee plans (91.6% for performance shares and stock options that vested under the 2013 plans). For more information about attainment levels and allocation rates for our stock option plans and performance share plans, see respectively "5.E - Stock option plans" and "5.F - Employee share ownership plans" below.

ITEM 6. DIRECTORS, SENIOR MANAGEMENT AND EMPLOYEES


▪	Since Olivier Bran dicourt received the same number of stock options and performance shares each year from 2016 to 2019, fluctuations in the Sanofi share price have had a significant impact on the pay ratio during this period.


▪	Business net income is a non-GAAP financial measure used by Sanofi and consolidated on a worldwide basis. The 2016 and 2017 business net income figures include the impacts of the first-time application of IFRS 15 (see Note A.2.1.1. to our consolidated financial statements for the ye ar ended December 31, 2018).

Regular benchmarking reviews are conducted to ensure that the level of compensation awarded to our employees and CEO is competitive and consistent with pharmaceutical industry levels.

Compensation and benefits of all kinds awarded in respect of 2020 to Serge Weinberg, Chairman of the Board of Directors

The components of the compensation awarded to the Chairman of the Board of Directors are described above in “Compensation policy for the Chairman of the Board of Directors”, within the section entitled “Compensation policy for corporate officers”.

Acting on a recommendation from the Compensation Committee, the Board of Directors, at its meeting on March 4, 2020, determined the components of Serge Weinberg’s compensation. Noting that Serge Weinberg's compensation had remained unchanged since he first assumed office in 2010, the Board of Directors decided to increase the amount of his annual fixed compensation to €800,000 as of the 2020 financial year.

Serge Weinberg does not receive any variable compensation, stock options or performance shares. He will not receive any compensation (i) for serving as a director or (ii) from any company included in Sanofi’s scope of consolidation within the meaning of Article L. 233-16 of the French Commercial Code.

His benefits in kind for 2020 comprise a company car with a chauffeur.

Compensation and benefits of all kinds awarded in respect of 2020 to Paul Hudson, Chief Executive Officer

Fixed and variable compensation

On March 4, 2020, acting on a recommendation from the Compensation Committee, the Board of Directors determined the components of Paul Hudson’s compensation for the 2020 financial year.

In line with our compensation policy for the Chief Executive Officer, as approved by our shareholders at the Annual General Meeting of April 30, 2019, his annual compensation for 2020 comprises (i) fixed annual gross compensation of €1,300,000 and (ii) variable annual compensation in a range from 0% to 250% of his fixed annual compensation, with a target of 150%, and subject to both quantitative and qualitative criteria.

Those objectives are 40% based on financial indicators (sales growth, business net income, free cash flow and BOI margin, each accounting for a quarter), and 60% based on specific individual objectives. Those individual objectives comprise:


▪	Growth of key new assets (10%);


▪	Business transformation (15%);


▪	Organization and people (10%);


▪	Pipeline (10%); and


▪	CSR (15%).

Equity-based compensation

Acting on a recommendation from the Compensation Committee, the Board of Directors meeting of March 4, 2020 proposed to award Paul Hudson 75,000 performance shares in respect of the 2020 financial year. In compliance with the AFEP-MEDEF Code, the entire amount of that award will be contingent upon both internal criteria (criteria based upon business net income and free cash flow (FCF)), and external criterion (criterion based on total shareholder return (TSR) relative to a benchmark panel of twelve of the leading global pharmaceutical companies, i.e. AstraZeneca plc, Bayer AG, Bristol-Myers-Squibb Inc., Eli Lilly and Company Inc., Johnson & Johnson Inc., GlaxoSmithKline plc, Merck Inc., Novartis AG, Pfizer Inc. et Roche Holding Ltd., Amgen et Novo Nordisk ).

In accordance with the compensation policy for the Chief Executive Officer, the award of performance shares to Paul Hudson will be subject to approval of the Chief Executive Officer's compensation package by our shareholders at the Annual General Meeting on the terms specified in Article L. 225-100 of the French Commercial Code. We will make the terms of the plan available on our corporate website (www.sanofi.com) in advance of the Annual General Meeting, scheduled for April 28, 2020.

In compliance with the AFEP-MEDEF Code, Paul Hudson is bound by insider trading rules (contained in the Board Charter) which stipulate periods during which he must refrain from trading in Sanofi shares.

In compliance with the AFEP-MEDEF Code and our Board Charter, Paul Hudson has undertaken to refrain from entering into speculative or hedging transactions, and so far as the Company is aware no hedging instruments have been contracted.

Transactions in shares by members of the Board of Directors and equivalent persons

As far as Sanofi is aware, transactions in our securities carried out during 2019 by (i) Board members, (ii) executives with the power to make management decisions affecting our future development and corporate strategy and (iii) persons with close personal ties to such individuals (as per Article L. 621-18-2 of the French Monetary and Financial Code), were as follows:


▪	on August 7, 2019, Christophe Babule (director) purchased 500 shares at a price of €73.09 per share;


▪	on November 4, 2019, Christophe Babule (director) purchased 500 shares at a price of €82.81 per share; and


▪	on December 13, 2019, Paul Hudson (director and Chief Executive Officer) purchased 5,600 shares at a price of €88.51 per share.

Service contracts

Neither we nor our subsidiaries have entered into service contracts with members of our Board of Directors or executive officers providing for any benefits. Details of compensation and other arrangements for our executive officers are provided at “ –B. Compensation – Compensation and arrangements for executive officers” above.




SANOFI / FORM 20-F 2019	123

ITEM 6. DIRECTORS, SENIOR MANAGEMENT AND EMPLOYEES

Compensation and arrangements for other Executive Committee members

Compensation

The compensation of Executive Committee members other than the Chief Executive Officer is reviewed by the Compensation Committee, taking into consideration the practices of leading global pharmaceutical companies.

In addition to fixed compensation, they receive variable compensation. Their target variable compensation depends on their position, and can represent up to 100% of their fixed compensation. The target amount of individual variable compensation is determined in line with market practice. It rewards the individual contribution of each Executive Committee member both to Sanofi’s performance and to the performance of the operations or functions for which he or she has responsibility.

For 2019, the variable component consisted of two elements:


▪	attainment of quantitative objectives (accounting for 50%) which are measured at consolidated level (sales growth 30%, business net income 40%, research and development outcomes 20%, and free cash flow 10%); and


▪	attainment of quantitative and qualitative objectives both individually (30%) and collectively (20%) within the Executive Committee (together accounting for 50%).

The indicators used are intended to measure growth (in terms of net sales, business net income, research and development outcomes, and free cash flow); talent and critical skills management, including raising the proportion of women in senior management positions; talent development in critical areas for Sanofi; and promotion of internal candidates to senior executive positions.

In addition, Executive Committee members may be awarded performance shares.

For 2019, the total gross compensation paid and accrued in respect of members of the Executive Committee (excluding the Chief Executive Officer) was €19 million, including €9 million in fixed compensation.

On April 30, 2019, a total of 330,147 performance shares were awarded to members of the Executive Committee (excluding the award to the Chief Executive Officer). No stock options were awarded in 2019 to members of the Executive Committee other than to the Chief Executive Officer.

In compliance with the AFEP-MEDEF Code, these entire awards are contingent upon two internal criteria, based on business net income (BNI) and free cash flow (FCF). Those criteria were selected because they align medium-term equity-based compensation with the strategy adopted by Sanofi. The Board of Directors (acting on a recommendation from the Compensation Committee) had previously decided to replace the performance criterion based on return on assets (ROA) with a criterion based on free cash flow (FCF). This applies to performance share plans awarded in and after 2019. The aim is to ensure that the compensation awarded remains aligned with our performance and our evolving strategy.

The arrangements relating to these awards are as follows:

▪

The performance criterion based on business net income accounts for 60% of the award. This criterion corresponds to the ratio, at constant exchange rates, of actual business net income to budgeted business net income. It represents the average actual-to-budget ratio attained over the entire period. Budgeted business net income is derived from the budget as approved by the Board of Directors at the beginning of each financial year. The business net income objective may not be lower than the bottom end of the full-year guidance range publicly announced by Sanofi at the beginning of each year. If the ratio is less than 95%, the corresponding options or performance shares are forfeited.



Business net income actual-to-budget attainment level (“R”)	Business net income allocation
If R is less than 95%	0	%
If R is 95%	50	%
If R is > 95% but < 98%	(50 + [(R –95) x 16])%
If R is ≥ 98% but ≤ 105%	R %
If R is > 105% but < 110%	(105 + [(R –105) x 3])%
If R is ≥ 110%	120	%


▪	The FCF criterion accounts for 40% of the award. It represents the average actual-to-budget ratio of free cash flow attained over the entire period. The award is based on a target FCF, below which some or all of the options or performance shares are forfeited.



FCF actual-to-budget attainment level ("F")	FCF allocation rate
If F is less than 40%	0	%
If F is > 40% but < 80%	[(F – 40) x 1.625]%
If F is 80%	65	%
If F is > 80% but < 100%	[(65 + [F – 80) x 1.75])%
If F is 100%	100	%
If F is > 100% but < 120%	F%
If F is ≥ 120%	120	%


▪	In order to align equity-based compensation with medium-term performance, performance is measured over three financial years.


▪	Vesting is subject to a non-compete clause.




124	SANOFI / FORM 20-F 2019

ITEM 6. DIRECTORS, SENIOR MANAGEMENT AND EMPLOYEES


▪	The entire award is forfeited in the event of resignation, or dismissal for gross or serious misconduct.


▪	In the event of individual dismissal other than for gross or serious misconduct or retirement before the age of 60, or if the beneficiary’s employer ceases to be part of the Sanofi group, the overall allocation percentage is prorated to reflect the amount of time the person remained with the Sanofi group during the vesting period.

▪

If any of the following events occur, full rights to the award are retained: (i) dismissal as part of a collective redundancy plan or of an equivalent collective plan negotiated and approved by the Chief Executive Officer of Sanofi; (ii) retirement on or after reaching the statutory retirement age, or early retirement under a statutory or contractual early retirement plan implemented by the relevant Sanofi entity and duly approved by the Chief Executive Officer of Sanofi; (iii) disability classified in the second or third categories stipulated in Article L. 314-4 of the French Social Security Code; and (iv) death of the beneficiary.

We publish in our Annual Report the level of attainment determined by the Board of Directors for performance conditions applicable to equity-based compensation plans awarded to the Chief Executive Officer and other members of the Executive Committee. The Board believes that disclosing the level of attainment allows our shareholders to better understand the demanding nature of the performance conditions.

The attainment levels for the most recent equity-based compensation plans are as follows:



	Attainment level		Allocation rate
	Business net income	ROA
June 24, 2015 plans	2015-2017: 102.2%	2015-2017: 2.1 percentage points above target	2015-2017: 100.3% ^(a)
May 4, 2016 plans	2016-2018: 102.5%	2016-2018: 1.2 percentage points above target	2016-2018: 101.5% ^(a)


(a)	Effectively 100%: the maximum number of exercisable options or shares to be delivered cannot be more than the number of options initially granted or performance shares initially awarded.

In 2019, 105,581 stock options were exercised by individuals who were Executive Committee members at the time of exercise.

All of the plans involved post-date the creation of the Executive Committee: Sanofi-Aventis plan of March 3, 2009, exercise price €45.09; Sanofi-Aventis plan of March 1, 2010, exercise price €54.12; Sanofi-Aventis plan of March 9, 2011, exercise price €50.48; Sanofi plan of March 5, 2012, exercise price €56.44 euros; Sanofi plan of March 5, 2013, exercise price €72.19; and Sanofi plan of March 5, 2014, exercise price €73.48.

Pension arrangements

The total amount accrued as of December 31, 2019 in respect of corporate pension plans for (i) corporate officers with current or past executive responsibilities at Sanofi (or companies whose obligations have been assumed by Sanofi) and (ii) members of the Executive Committee was €48 million. That amount includes a gain of €16 million recognized in profit or loss during 2019, which takes account of the favorable impact of amendments to the top-up pension plan following the Order of July 3, 2019 transposing European Directive 2014/50/EU of April 16, 2014 into French law.

C. Board Practices

Neither we nor our subsidiaries have entered into service contracts with members of our Board of Directors or corporate officers providing for benefits upon termination of employment. With respect to the Chief Executive Officer, see also “-B. Compensation - Compensation and arrangements for corporate officers” above.

Application of the AFEP-MEDEF Code

The AFEP-MEDEF Code requires us to report specifically on the application of its recommendations and if any of them have not been applied, explain why. Currently our departures from this Code are as follows:



Paragraph of the AFEP-MEDEF Code	Recommendation of the AFEP-MEDEF code	Application by Sanofi
9.2 Evaluation of the Board of Directors	The evaluation has three objectives: ▪ […] ;	The evaluation of the Board conducted at the end of 2018 included an assessment of the actual contribution of each director to the Board’s work.
	▪ measure the actual contribution of each director to the Board’s work.	More generally, the issue of competence and individual contribution to the work of the Board and its Committees is addressed on a continuous basis, with a specific review when a director is up for reappointment as a Board or Committee member.
		Annual evaluations are conducted using a detailed questionnaire. The questionnaire deals specifically with the operating procedures of the Board and gives directors an opportunity to express freely their assessment of the individual contributions of other directors. These evaluations may be followed by individual meetings with the Secretary to the Board, at which the responses to the questionnaire are analyzed and discussed.
17.1. Membership of the Compensation Committee	It is recommended that one of its members be an employee director.	The Board intends to appoint a director representing employees to the Compensation Committee after an induction period that will give that director time to adapt to how the Company operates, understand its specific characteristics, familiarize himself or herself with the challenges and broad outlines of the Board’s remit, and undertake any necessary training.
23.2 Non-competition agreement	In any event, no benefit can be paid over the age of 65.	Under the compensation policy for our Chief Executive Officer, he undertakes in the event he leaves the Company not to join a competitor of the Company as an employee or corporate officer, or to provide services to or cooperate with such a competitor. In return for this undertaking, he receives an indemnity corresponding to one year’s total compensation based on his fixed compensation effective on the day he ceases to hold office and the last individual variable compensation received prior to that date. The indemnity is payable in 12 monthly installments. The Board of Directors, acting on a recommendation of the Compensation Committee, decided not to alter the compensation policy and non-compete undertaking of the Chief Executive Officer such that his indemnity would not be payable after he reaches the age of 65. Apart from the fact that the AFEP-MEDEF recommendation is contrary to the principle of the strict enforceability of legally constituted contractual arrangements, it is also out of line with the actual situation. In practice, many executive officers continue to work after they leave office, often in a consultancy role. Consequently, implementing the AFEP-MEDEF recommendation would put Sanofi at risk of having no legal protection if the Chief Executive Officer were to take up an activity in competition with the Company immediately after leaving office. However, the Board of Directors may decide at the time the Chief Executive Officer leaves office (regardless of his age) to release him from the non-compete undertaking for some or all of the 12-month period. In such a case, the non-compete indemnity would not be due for the period of time waived by the Company.

Activities of the Board of Directors in 2019

During 2019 , the Board of Directors met 13 times, with an overall attendance rate among Board members of 94%. This attendance rate includes participation by conference call, though only a small number of Directors participated in this way. Individual attendance rates varied between 77% and 100%.

The following persons attended meetings of the Board of Directors:


▪	the dir ectors;


▪	the Secretary to the Board;


▪	frequently: members of the Executive Committee; and


▪	occasionall y: the statutory auditors, managers of our global support functions, and other company employees.

The agenda for each meeting of the Board is prepared by the Secretary after consultation with the Chairman, taking account of the agendas for the meetings of the specialist Committees and the suggestions of the directors.

Approximately one week prior to each meeting of the Board of Directors, the directors each receive a file containing the agenda, the minutes of the previous meeting, and documentation relating to the agenda.

The minutes of each meeting are expressly approved at the next meeting of the Board of Directors.

In compliance with our Board Charter, certain issues are examined in advance by the various Committees according to their areas of competence to enable them to make a recommendation; those issues are then submitted for a decision by the Board of Directors.

Since 2016, acting on a recommendation from the Appointments, Governance and CSR Committee, the Board has held at least two executive sessions (i.e. meetings held without the Chief Executive Officer present) per year. If the Chairman of the Board so decides, such sessions may also be held without the directors representing employees (or any other Sanofi employee) being present. The primary purpose of such sessions is to evaluate the way the Board and its Committees operate, to discuss the performance of the Chief Executive Officer, and to debate succession planning. Two executive sessions took place in 2019, on March 8 and April 19.

In 2019 , the main activities of the Board of Directors related to the following issues:

Activities of the Board Committees in 2019

Since 1999, our Board of Directors has been assisted in its deliberations and decisions by specialist Committees (see our Board Charter, provided as Exhibit 1.2 to this Annual Report on Form 20-F). Chairmen and members of these Committees are chosen by the Board from among its members, based on their experience.

The Committees are responsible for the preparation of certain items on the agenda of the Board of Directors. Decisions of the Committees are adopted by a simple majority with the chairman of the Committee having a casting vote. Minutes are drafted, and approved by the Committee members.

The chairman of each Committee reports to the Board on the work of that Committee, so that the Board is fully informed whenever it takes a decision.

(1) Christian Mulliez resigned from his directorship on February 6, 2019.

Directors who were absent from some meetings provided clear and substantiated explanations for their absence, which related mainly to personal matters or to unscheduled meetings called at short notice (especially where sudden developments on an ongoing project necessitated a Board meeting). The Board pays particular attention to the availability of directors, and makes sure that their other professional commitments do not prevent them from fully discharging their remit with respect to the Company.

Industrial Relations

In all countries where we operate, we seek to strike a balance between our economic interests and those of our employees, which we regard as inseparable.

Our responsibility towards our employees is based on the basic principles of our Social Charter, which outlines the rights and duties of all Sanofi employees. The Social Charter addresses our key commitments towards our workforce: equal opportunity for all people without discrimination, the right to health and safety, respect for privacy, the right to information and professional training, social protection for employees and their families, freedom of association and the right to collective bargaining, and respect for the principles contained in the Global Compact on labor relations and ILO treaties governing the physical and emotional well-being and safety of children.

Our labor relations are based on respect and dialogue. In this spirit, management and employee representatives meet regularly to exchange views, negotiate, sign agreements and ensure that agreements are being implemented.

Employee dialogue takes place in different ways from country to country, as dictated by specific local circumstances. Depending on the circumstances, employee dialogue relating to information, consultation and negotiation processes may take place at national, regional or company level. It may be organized on an interprofessional or sectorial basis, or both. Employee dialogue may be informal or implemented through a specific formal body, or a combination of both methods. Whatever the situation, Sanofi encourages employees to voice their opinions, help create a stimulating work environment and take part in decisions aiming to improve the way we work. These efforts reflect one of the principles of the Social Charter, whereby improving working conditions and the necessary adaptation to our business environment go hand-in-hand.

Profit-sharing Schemes, Employee Savings Schemes and Employee Share Ownership

Profit-sharing Schemes

All employees of our French companies belong to voluntary and statutory profit-sharing schemes.

Voluntary Schemes

Voluntary schemes ( intéressement des salariés ) are collective schemes that are optional for the employer and contingent upon performance. The aim is to give employees an interest in the growth of the business and improvements in its performance.

The amount distributed by our French companies during 2019 in respect of voluntary profit-sharing for the year ended December 31, 2018 represented 0.84% of total payroll.

In June 2017, we entered into a new fixed-term statutory profit-sharing agreement for the 2017, 2018 and 2019 financial years. That agreement applies to all employees of our French companies. Under the agreement, Sanofi pays collective variable compensation determined on the basis of the more favorable of (i) growth in consolidated net sales (at constant exchange rates and on a constant structure basis) or (ii) the level of business net income. For each of those criteria, a matrix determines what percentage of total payroll is to be allocated to the scheme. This overall allocation is then reduced by the amount required by law to be transferred to a special profit-sharing reserve. The balance is




SANOFI / FORM 20-F 2019	133

ITEM 6. DIRECTORS, SENIOR MANAGEMENT AND EMPLOYEES

then distributed between the employees unless the transfer to the reserve exceeds the maximum amount determined under the specified criteria, in which case no profit share is paid to the employees.

Statutory Scheme

The statutory scheme ( p articipation des salaries aux résultats de l’entreprise ) is a French legal obligation for companies with more than 50 employees that made a profit in the previous financial year.

The amount distributed by our French companies during 2019 in respect of the statutory scheme for the year ended December 31, 2018 represented 8.08% of total payroll.

Distribution Formula

In order to favor lower-paid employees, the voluntary and statutory profit-sharing agreements entered into since 2005 split the benefit between those entitled as follows:


▪	60% prorated on the basis of time spent in the Company’s employment in the year; and


▪	40% prorated on the basis of gros s annual salary during the year, subject to a lower limit equal to the social security ceiling and an upper limit of three times the social security ceiling.

Employee Savings Schemes and Collective Retirement Savings Plan

The employee savings arrangements operated by Sanofi are based on a collective savings scheme ( Plan d’Epargne Groupe ) and a collective retirement savings scheme ( Plan d’Epargne pour la Retraite Collectif ). Those schemes reinvest the sums derived from the statutory and voluntary profit-sharing schemes, plus voluntary contributions from employees.

In June 2019, 92.5% of the employees who benefited from the profit-sharing schemes opted to invest in the collective savings scheme, and more than 80% opted to invest in the collective retirement savings scheme.

Sanofi supplements the amount invested by employees in these schemes by making a top-up contribution.

In 2019, €114.4 million and €56.5 million were invested in the collective savings scheme and the collective retirement savings scheme respectively through the voluntary and statutory schemes for 2018, and through top-up contributions.

Employee Share Ownership

As of December 31, 2019 , shares held under the collective savings scheme by employees of Sanofi, employees of related companies and former employees amounted to 1.64% of our share capital.

For more information about our most recent employee share ownership plan, refer to “Item 10. Additional Information - Changes in Share Capital - Increases in Share Capital”.

ITEM 6. DIRECTORS, SENIOR MANAGEMENT AND EMPLOYEES

E. Share Ownership

Senior Management

Members of the Executive Committee hold shares of our Company amounting in the aggregate to less than 1% of our share capital.

During 2019 , 108,581 stock options were exercised by individuals who were members of the Executive Committee when they exercised.

Existing Option Plans as of December 31, 2019

Until 2018, Sanofi restricted stock option plans were granted to a limited number of senior executives, so as to limit dilution for our shareholders. All awards of stock options were fully contingent upon performance targets being achieved over three financial years.

With effect from 2018, only the Chief Executive Officer was awarded stock options. Consequently, the Board awarded no stock options at its meeting of April 30, 2019 other than the 220,000 stock subscription options awarded to Olivier Brandicourt. The number of options awarded to the Chief Executive Officer in 2019 represents 3.51% of the total limit approved by the Shareholders’ Annual General Meeting of April 30, 2019 (0.5% of our share capital).

During 2019, the Board of Directors reviewed its compensation policy and decided that stock options would no longer be awarded in or after 2020. That decision was taken to standardize the terms of equity-based compensation awards within Sanofi, and in response to feedback from some shareholders and proxy advisors who have concerns about stock options given their dilutive effect and potential unintended consequences.

A new voluntary profit-sharing agreement was signed in June 2017 which gives all of our employees an interest in Sanofi’s performance (for more details refer to “Profit-Sharing Schemes, Employee Savings Schemes and Employee Share Ownership”, above).

Share Purchase Option Plans

As of December 31, 2019 there were no stock purchase option plans outstanding. The last such plan still outstanding as of December 31, 2018 expired on March 30, 2019.

ITEM 6. DIRECTORS, SENIOR MANAGEMENT AND EMPLOYEES

The main characteristics of our stock options are also described in Note D.15.8. to our consolidated financial statements, included in Item 18 of this annual report.

Existing Restricted Share Plans as of December 31, 2019

The Board of Directors awards shares to certain employees in order to give them a direct stake in our future and performances via trends in the share price, as a partial substitute for the granting of stock options.

Shares are awarded to employees by the Board of Directors on the basis of a list submitted to the Compensation Committee. The Board of Directors sets terms of the awards, including continuing employment conditions and performance conditions (measured over three financial years).

The plans have a three-year vesting period, with no lock-up period.

At its meeting of April 30, 2019, the Board of Directors awarded two plans, in addition to the plan awarded to the Chief Executive Officer:


▪	a “France” plan, under which 2,430 beneficiaries were awarded a total of 1,243,434 shares; and


▪	an “International” plan, under which 5,282 beneficiaries were awarded a total of 2,504,148 shares.

Of the 7,713 beneficiaries, 45% were women.

The entire award is contingent upon the same criteria, based on business net income and free cash flow (FCF), as the award made to members of the Executive Committee. The attainment levels are also the same as for awards made to members of the Executive Committee. Vesting is subject to a non-compete clause.

The number of shares awarded to Olivier Brandicourt in 2019 represents 0.26% of the total limit approved by our shareholders at the Annual General Meeting of April 30, 2019, 0.004% of our share capital at the date of grant, and 1.33% of the total amount awarded to all beneficiaries .

The 2019 awards represent a dilution of approximately 0.30% of our undiluted share capital as of December 31, 2019 .

Not all of our employees were awarded performance shares, but a new voluntary profit-sharing agreement was signed in June 2017 which gives all of our employees an interest in Sanofi’s performance (for more details refer to “- Profit-Sharing Schemes, Employee Savings Schemes and Employee Share Ownership”, above).

(b)	Shares held via the Sanofi Group Employee Savings Plan.


(c)	Number of share repurchased as from January 1st, 2020 under the share repurchase program in force.


(d)	Based on the total number of voting rights as of January 31, 2020.


(e)	Based on the total number of voting rights as of January 31, 2020 as published in accordance with article 223-11 and seq. of the General Regulations of the Autorité des marchés financiers (i.e. including treasury shares, the voting rights of which are suspended).

Our Articles of Association provide for double voting rights for shares held in registered form for at least two years. All of our shareholders may benefit from double voting rights if these conditions are met, and no shareholder benefits from specific voting rights. For more information relating to our shares, see “Item 10. Additional Information - B. Memorandum and Articles of Association.”

Neither L’Oréal nor BlackRock holds different voting rights from those of our other shareholders.

To the best of our knowledge, no other shareholder currently holds, directly or indirectly and acting alone or in concert, more than 5% of our share capital or voting rights. Furthermore, we believe that we are not directly or indirectly owned or controlled by another corporation or government, or by any other natural or legal persons. To our knowledge, there are no arrangements that may result in a change of control.

During the year ended December 31, 2019 we received several share ownership declarations informing us that a legal threshold had been passed, as required under Article L. 233-7 of the French Commercial Code.

BlackRock Inc., acting on its behalf as well as on behalf of its affiliates, has in 2019 stated having alternatively crossed upwards and downwards the 5% threshold in terms of voting rights, and according to the last available data holds 5.90% of the share capital and 5.26% of the voting rights (December 9, 2019 declaration).

In addition to the statutory requirement to inform the Company and the Autorité des marchés financiers (AMF, the French financial markets regulator) that they hold a number of shares (or of securities equivalent to shares or of voting rights pursuant to Article L. 233-9 of the French Commercial Code) representing more than one twentieth (5%), one tenth (10%), three twentieths (15%), one fifth (20%), one quarter (25%), three tenths (30%), one third (1/3), one half (50%), two thirds (2/3), nine tenths (90%) or nineteen twentieths (95%) of the share capital or theoretical voting rights within four trading days after crossing any such ownership threshold (Article L. 233-7 of the French Commercial Code), any natural or legal person who directly or indirectly comes to hold a percentage of the share capital, voting rights or securities giving future access to the Company’s capital that is equal to or greater than 1% or any multiple of that percentage, is obliged to inform the Company thereof by registered mail, return receipt requested, indicating the number of securities held, within the five trading days following the date on which each of the thresholds was crossed.

If such declaration is not made, the shares in excess of the fraction that should have been declared will be stripped of voting rights at shareholders’ meetings if on the occasion of such meeting the failure to declare has been formally noted and one or more shareholders collectively holding at least 5% of the Company’s share capital or voting rights so request at that meeting.

Any natural or legal person is also required to inform the Company, in the forms and within the time limits stipulated above for passing above a threshold, if their direct or indirect holding passes below any of the aforementioned thresholds.

Since January 1, 2020 we have not received any share ownership declaration.

As of December 31, 2019, individual shareholders (including employees of Sanofi and its subsidiaries, as well as retired employees holding shares via the Sanofi Group Employee Savings Plan) held approximately 7.00% of our share capital. Institutional shareholders (excluding L’Oréal) held approximately 77.43% of our share capital. Such shareholders are primarily American (26.58%), French (16.24%) and British (14.41%). German institutions held 4.08% of our share capital, Swiss institutions held 1.95%, institutions from other European countries held 7.69% and Canadian institutions held 1.71% of our share capital. Other international institutional investors (excluding those from Europe and North America) held approximately 4.79% of our share capital. In France, our home country, we have 10,081 identified shareholders of record. In the United States, our host country, we have 52 identified shareholders of record and 17,552 identified ADS holders of record.

A. Consolidated Financial Statements and Other Financial Information

Our consolidated financial statements as of and for the years ended December 31, 2019 , 2018 and 2016 are included in this annual report at “Item 18. Financial Statements.”

Dividends on Ordinary Shares

We paid annual dividends for the years ended December 31, 2015 , 2016 , 2017 and 2018 and our shareholders will be asked to approve the payment of an annual dividend of 3.15 per share for the 2019 fiscal year at our next annual shareholders’ meeting. If approved, this dividend will be paid on May 6, 2020.

We expect that we will continue to pay regular dividends based on our financial condition and results of operations. The proposed 2019 dividend equates to a distribution of 52.6 % of our business net income. For information on the non-GAAP financial measure “business earnings per share” see “Item 5. Operating and Financial Review and Prospects - Business Net Income.”

The following table sets forth information with respect to the dividends paid by our Company in respect of the 2015 , 2016 , 2017 and 2018 fiscal years and the dividend that will be proposed for approval by our shareholders in respect of the 2019 fiscal year at our May 13, 2019 shareholders’ meeting.

(a)	Proposal, subject to shareholder approval.


(b)	Based on the relevant year-end exchange rate.

The declaration, amount and payment of any future dividends will be determined by majority vote of the holders of our shares at an ordinary general meeting, following the recommendation of our Board of Directors. Any declaration will depend on our results of operations, financial condition, cash requirements, future prospects and other factors deemed relevant by our shareholders. Accordingly, we cannot assure you that we will pay dividends in the future on a continuous and regular basis. Under French law, we are required to pay dividends approved by an ordinary general meeting of shareholders within nine months following the meeting at which they are approved.

Disclosure pursuant to Section 13(r) of the United States Exchange Act of 1934

Sanofi conducts limited business relating to human health products with Iran, which contributed well under 1% of Sanofi’s consolidated net sales in 2019 . These activities, which are not financially material to Sanofi, are being disclosed pursuant to Section 13(r) of the United States Exchange Act of 1934, as amended. Sales consisted of bulk and branded pharmaceuticals, and vaccines. US affiliates of Sanofi, or foreign affiliates controlled by US affiliates of Sanofi, are either not involved in these activities or operate under licenses issued by the US Treasury Department’s Office of Foreign Assets Control. Limited business amounting to approximately €22.8 million in gross revenues has been conducted by non-US subsidiaries of Sanofi not requiring an OFAC license with entities such as public hospitals or distributors tied to the Ministry of Health. It is estimated that this activity contributed no more than €4.2 million to net profits. A representative office in Tehran incurs incidental expenses from state-owned utilities.

In January 2016, Sanofi and the Iran Food and Drug Administration, affiliated with the Ministry of Health and Medical Education of the Islamic Republic of Iran, signed a Memorandum of Cooperation (MOC) regarding (i) potential future projects to reinforce current partnerships with reputable Iranian manufacturers (in particular to enhance industrial quality standards), (ii) collaborating with the Ministry of Health on programs for the prevention and control of certain chronic and non-communicable diseases (in particular diabetes) and (iii) potential future collaboration on epidemiological studies.

Following the MOC, Sanofi and the Iranian company Barkat Pharmed Co. entered into a non-binding letter of intent on June 16, 2017 to evaluate the possibility of a transaction involving the creation of a joint venture, or other possible forms of transaction, the business purpose of which would be the manufacturing and distribution of pharmaceutical products in Iran. The letter of intent expired in 2018.

The MOC did not generate any revenue or net profit in 2019.

Sanofi has determined that its activities are compliant with applicable law. In light of the nature of the activities concerned, Sanofi and its affiliates intend to continue their activities in Iran.

Information on Legal or Arbitration Proceedings

This Item 8 incorporates by reference the disclosures found in Note D.22. to the consolidated financial statements at Item 18 of this annual report; material updates thereto as of the date of this annual report are found below under the heading “- B. Significant Changes - Updates to Note D.22”.

Sanofi and its subsidiaries are involved in litigation, arbitration and other legal proceedings. These proceedings typically are related to product liability claims, intellectual property rights (particularly claims against generic companies seeking to limit the patent protection of Sanofi products), competition law and trade practices, commercial claims, employment and wrongful discharge claims, tax assessment claims, waste disposal and pollution claims, and claims under warranties or indemnification arrangements relating to business divestitures. As a result, we may become subject to substantial liabilities that may not be covered by insurance and could affect our business and reputation. While we do not currently believe that any of these legal proceedings will have a material adverse effect on our financial position, litigation is inherently unpredictable. As a consequence, we may in the future incur judgments or enter into settlements of claims that could have a material adverse effect on results of operations, cash flows and/or our reputation.

Patents

Lantus ^® Mylan Patent Litigation (United States)

In June 2017, Mylan Pharmaceuticals, Inc. filed petitions for Inter Partes Review (IPR) for US Patent Nos. 7,476,652 and 7,713,930 regarding Lantus ^® with the United States Patent Office Patent Trial and Appeal Board (PTAB). In these petitions, Mylan attacks the validity of all claims of these patents. In December 2017, the PTAB decided to move forward with Mylan’s IPRs for these two patents. In December 2018, the PTAB issued a decision invalidating the claims of the two formulation patents. In November 2019, a panel of three judges of the United States Court of Appeals for the Federal Circuit issued a divided public ruling affirming the December 2018 PTAB decisions invalidating the Lantus ^® formulation patents. On January 28, 2020, our petition for rehearing by the full Federal Circuit was denied. Sanofi intends to challenge this ruling.

In October 2017, several Sanofi entities filed a patent infringement suit against Mylan N.V., Mylan GmbH, Mylan Inc., and Mylan Pharmaceuticals Inc. (collectively, “Mylan”) in the United States District Courts for the District of New Jersey and Northern District of West Virginia. In its suits, Sanofi alleges infringement of several patents. The suits were triggered by a notification received from Mylan in mid-September 2017, in which Mylan stated that it had filed an 505(b)(2) NDA with the FDA for insulin glargine drug pen and vial products. Mylan also stated that its NDA included a paragraph IV certification challenging all of the Sanofi patents then listed in the FDA Orange Book for Sanofi’s Lantus ^® and Lantus ^® SoloStar ^® products. These suits resulted in a stay during which the FDA cannot approve Mylan’s NDA. The 30 - month stay is expected to expire on the earlier of (i) March 18, 2020 or (ii) a court decision in favor of Mylan. In February 2018, the West Virginia case was dismissed and the parties are proceeding only with the New Jersey lawsuit. Biocon Ltd., Biocon Research Ltd., Biocon SDN.BHD., and Biocon S.A., were added to the New Jersey lawsuit in July 2018. In December 2019, trial took place in the New Jersey District Court concerning the infringement of US Patent No. 8,603,044 by Mylan’s pen product, as well as this patent’s validity. We expect a ruling from the New Jersey District Court in Q1 2020.

In September 2018, Mylan filed 10 petitions asking the PTAB to commence IPR proceedings of US Patent Nos. 8,603,044, 8,679,069, 8,992,486, 9,526,844, and 9,604,008, challenging the validity of certain claims of these Sanofi patents. The PTAB decided to move forward with nine of the 10 IPR proceedings concerning these five patents and written decisions concerning validity are expected from the PTAB starting in April 2020 . Pfizer Inc. joined eight of these nine IPRs, and filed a separate IPR concerning US Patent No. 8,679,069 where we expect a written decision concerning validity in August 2020. In October 2019, Mylan filed two petitions asking the PTAB to commence IPR proceedings of US Patent No. RE47,614, challenging the validity of the claims of this Sanofi patent. The PTAB will determine whether to move forward with these IPRs in April 2020.

Cerdelga ^® Patent Litigation (United States)

Cerdelga ^® is covered by four Orange Book listed patents US 6,916,802, US 7,196,205, US 7,253,185, and US 7,615,573. In the fourth quarter of 2018, six different generic manufacturers each separately notified Sanofi-Genzyme that they had filed ANDA applications for Cerdelga ^® with Paragraph IV certifications challenging the US ‘802, ‘205, ‘185 and ‘573 patents. Sanofi-Genzyme filed suit against each ANDA filer within 45 days of receipt of each notification in the US District Court for the District of Delaware. The associated 30-month stay of FDA approval on each ANDA is expected to expire on the earlier of (i) February 19, 2022 or (ii) a court decision in favor of the generic manufacturer(s). Sanofi-Genzyme has settled with two of the defendants (Cipla Limited; Zenara Pharma Private Limited). A trial is scheduled to begin in March 2021.

Government Investigations and Related Litigation

From time to time, subsidiaries of Sanofi are subject to governmental investigations and information requests from regulatory authorities inquiring as to the practices of Sanofi with respect to the sales, marketing, and promotion of its products.

In December 2013, Genzyme entered into a settlement agreement to resolve civil claims arising out of the investigation into promotional practices of Seprafilm ^® and paid in that respect approximately $23 million. As part of this settlement, and as part of the settlement entered into by Sanofi US in December 2012 relating to civil claims arising out of an investigation into sampling of its former product Hyalgan ^® for which Sanofi US paid $109 million, the companies entered into a Corporate Integrity Agreement (“CIA”) with the Office of the Inspector General of the United States Department of Health and Human Services in September 2015. Also in September 2015, Genzyme entered into a Deferred Prosecution Agreement (“DPA”) with the US Department of Justice and paid in that respect approximately $33 million to resolve the Seprafilm ^® matter completely. The DPA expired in September 2017 and the CIA is currently in effect.

In April 2018, a lawsuit was unsealed in the US District Court for the Southern District of New York, alleging violations of the False Claims Act and 29 state-law analogs by Sanofi US and other manufacturer and PBM defendants. The complaint had first been filed on October 6, 2015. It was unsealed after the federal and state governments declined to intervene. In October and December 2018, the defendants (including Sanofi) and the United States separately moved to dismiss the complaint, over the relator’s objections. The Court dismissed the case in July 2019, and the relator filed a notice of appeal in September 2019. The appeal is now pending before the US Court of Appeals for the Second Circuit.

In June 2016, the United States declined to intervene in a False Claims Act action filed in Federal Court in New Jersey regarding the sale and marketing of and variability of response to Plavix ^® . The relator appealed the dismissal of the complaint. Sanofi US is defending this action as well as two State Attorney General actions (Hawaii and New Mexico) concerning the sale and marketing of Plavix ^® . In Hawaii, trial is set for May 2020. In New Mexico, Sanofi's appeal of the trial court's denial of our motion to dismiss is currently pending before the New Mexico Supreme Court.

In December 2016 and January 2017, two putative class actions were filed against Sanofi US and Sanofi GmbH in Federal Court in Massachusetts on behalf of direct-purchasers of Lantus ^® alleging certain antitrust violations. In January 2018, the District Court of Massachusetts dismissed Plaintiffs’ complaint against Sanofi. The dismissal of Plaintiffs’ entire case was without prejudice. Plaintiffs appealed that order to the Court of Appeals for the First Circuit, which issued its decision on February 13, 2020 reversing and remanding to the district court.

In early 2017, four actions (now consolidated and captioned “In re Insulin Pricing”) were filed against Sanofi US in Federal Court in New Jersey on behalf of a putative class of diabetes patients alleging violations of the Racketeer Influenced and Corrupt Organizations Act (“RICO Act”) and various state unfair/deceptive trade practices statutes in connection with the pricing of Lantus ^® , Apidra ^® , and Toujeo ^® . In February

ITEM 8. FINANCIAL INFORMATION

2020, the Court dismissed the RICO claims, and allowed some state law claims to proceed. The parties were ordered to commence discovery in September 2019.

Separately, a case ( MSP Recovery Claims, Series LLC ) was filed in February 2018 in the New Jersey Federal Court against Sanofi US Like the plaintiffs in ”In re Insulin Pricing” matter, the Medicare Secondary Payers ( the "MSPs") assert RICO claims and state consumer-protection claims (as well as claims for fraud and unjust enrichment) premised on the pricing of the manufacturers’ insulin drugs. In February 2020, the Court dismissed the RICO counts and some state law claims, but allowed other state law claims to proceed.

In May 2019, Kentucky filed its own complaint in Kentucky State Court on behalf of Kentucky diabetes patients asserting two causes of action for violations of Kentucky consumer-protection statutes and one cause of action for unjust enrichment, each premised on the pricing of insulin products. In January 2020, the court denied the Defendants’ motion to dismiss.

In November 2019, Harris County, Texas filed a lawsuit in Texas State Court against Sanofi US, premising its claims on the pricing of the manufacturers’ insulin drugs. In December 2019, defendants removed the case to federal court in the Southern District of Texas.

In January 2017, the Minnesota State Attorney General’s office issued a Civil Investigative Demand (CID) calling for the production of documents and information relating to pricing and trade practices for Lantus ^® and Toujeo ^® , from January 1, 2008 through present. In October 2018, the State of Minnesota, through its Attorney General, filed a complaint in Federal Court in New Jersey against Sanofi US. The complaint asserts claims on behalf of Minnesota diabetes patients and the Minnesota Department of Corrections, all premised on the pricing of manufacturers’ insulin products. The motion to dismiss has been pending since November 2019.

In March 2017, the Washington State Attorney General’s office issued a Civil Investigative Demand (CID) calling for the production of documents and information relating to pricing and trade practices for Sanofi’s injectable insulin products, from January 1, 2005 through present. Sanofi US is cooperating with this investigation.

In August 2017, Sanofi US received a Civil Investigative Demand (CID) from the US Attorney’s Office for the Southern District of New York requesting documents and information relating to Sanofi US’s certified diabetes educator program during the period from 2007 to the present. In September 2018, the US Attorney’s Office elected to decline intervention in the underlying False Claims Act suit and in February 2019, the Court dismissed the suit without prejudice.

In April 2018, Sanofi US received a set of interrogatories from the California State Attorney General’s office regarding the 2014-2015 litigations and settlement between Sanofi and Eli Lilly related to Lantus ^® patents and the launch of Basaglar ^® . Sanofi US finished responding to these interrogatories in October 2019. In February 2020, the California State Attorney General’s office issued a follow-up subpoena for documents related to competition for Lantus ^® . Sanofi US will respond as appropriate to the subpoena in an effort to bring the matter to closure.

In July 2019, Sanofi US received a subpoena from the New York State Office of the Attorney General requesting the production of documents relating to marketing, pricing and trade practices for Sanofi’s injectable insulin products from July 2013 to present. Sanofi US is cooperating with this investigation.

In December 2019, Sanofi US received a Civil Investigative Demand (CID) from the Office of the Attorney General of the State of Colorado requesting written responses and the production of documents relating to pricing and trade practices for Sanofi’s insulin products from January 2010 to present. Sanofi US is cooperating with this investigation.

In January 2018, Sanofi US received a subpoena from the US Attorney’s Office for the District of Massachusetts requesting documents and information relating to Sanofi US’s relationship with non-profit organizations that provide assistance to patients taking Sanofi drugs and Sanofi US’s patient assistance programs as well as documents and information relating to the sale and marketing of Aubagio ^® and Lemtrada ^® . On February 28, 2020, Sanofi US entered into a Civil Settlement with the United States Department of Justice and agreed to pay approximately $11.85 million to resolve allegations regarding certain charitable donations Sanofi US made to an independent patient assistance foundation that assisted patients being treated for Multiple Sclerosis. In connection with this settlement, Sanofi US also entered into a Corporate Integrity Agreement (“CIA”) with the Office of the Inspector General for the United States Department of Health and Human Services effective the same day which will require the Company to continue certain compliance requirements in the US. This settlement concludes the US Government investigation initiated in 2018.

In September 2019, Sanofi US received a Civil Investigative Demand (CID) from the Department of Justice concerning Dupixent ^® , Kevzara ^® , Praluent ^® and Zaltrap ^® . The CID requests documents and information relating to Sanofi US’s payments made to healthcare providers. Sanofi US is cooperating with this investigation.

In February 2020, Genzyme Corporation received a Civil Investigative Demand (CID) from the Department of Justice. The CID requests documents and information relating to Genzyme Corporation’s payments made to vendors or developers of electronic health record technology. Genzyme Corporation is cooperating with this investigation.

In France, in the claim concerning allegations that Sanofi’s communication and promotional practices inhibited the entry on the market of generics of clopidogrel (the active ingredient of Plavix ^® ), the French Antitrust Authority issued its decision on May 14, 2013, imposing on Sanofi a fine of €40.6 million. In December 2014, the Paris Court of Appeals rejected Sanofi’s appeal and confirmed in totality the decision. Sanofi filed a “ pourvoi ” with the French Supreme Court ( Cour de cassation ) in January 2015. As a consequence of the May 2013 ruling, claims were filed by Sandoz and by Teva in 2014 before the Commercial Court of Paris for compensation of their alleged damages: loss of margin and other ancillary damages (legal fees to external counsel, image and reputation). In June and November 2016 respectively, settlement agreements were entered into with Sandoz and Teva. Consequently, they subsequently withdrew their civil claims, jointly and severally. On October 18, 2016, the Supreme Court confirmed the Court of Appeals’ decision. Therefore, the Court of Appeals’ decision became definitive. In September 2017, Sanofi and Sanofi-Aventis France received a summons before the Paris Commercial Court from the French Caisse Nationale d’Assurance Maladie - CNAM (French Social Security) claiming €115.8 million for their alleged damages. On October 1, 2019, the Paris Commercial Court dismissed the CNAM’s action as time barred. In November 2019, the CNAM lodged an appeal.

Following the September 2018 civil settlement with the US SEC fully resolving the SEC’s investigation into possible violation of the US FCPA, Sanofi agreed to a two-year period of self-reporting on the effectiveness of its enhanced internal controls which is still ongoing.

ITEM 8. FINANCIAL INFORMATION

B. Significant Changes

Updates to Note D.22

Boehringer Ingelheim (BI) Retained Liabilities

On February 18, 2020, Boehringer Ingelheim (BI) filed an ICC (International Chamber of Commerce) Arbitration in Geneva demanding that Sanofi indemnify it for its loss related to the Zantac ^® litigation that has been filed in the United States. Sanofi refutes this claim and is planning on defending that action as well as asserting its own claims for indemnity under the relevant agreements.

Other Changes

On February 18, 2020, Sanofi Pasteur, the Vaccines Global Business Unit of Sanofi, announced that it will leverage previous development work for a SARS vaccine which may unlock a fast path forward for developing a COVID-19 vaccine. Sanofi will collaborate with the Biomedical Advanced Research and Development Authority (BARDA), part of the Office of the Assistant Secretary for Preparedness and Response, expanding the Company’s long-standing partnership with BARDA.

On February 24, 2020, Sanofi announced its plans to create a major leading European company dedicated to the production and marketing to third parties of active pharmaceutical ingredients (API), which are the essential molecules responsible for the beneficial effects used in the composition of any drug. The project consists of creating a standalone company which would combine Sanofi’s API commercial and development activities with six of its European API production sites : Brindisi (Italy), Frankfurt Chemistry (Germany), Haverhill (UK), St Aubin les Elbeuf (France), Újpest (Hungary) and Vertolaye (France). With increasing medicine shortages that critically impact patient care, the new entity would contribute to supporting and securing API manufacturing as well as supply capacities for Europe and beyond. The new company would rank as the world's second largest API company with approximately €1 billion in expected sales by 2022. It is expected to include 3,100 skilled employees and to be headquartered in France. A planned IPO on Euronext Paris would be evaluated with a decision expected by 2022, subject to market conditions. Sanofi is fully committed to the new company’s success and intends to establish a long-term customer relationship with the new API supplier and to hold a minority stake of approximately 30% in the new company.

On February 28, 2020, Aventis Inc., a subsidiary of Sanofi, acquired from Bristol-Myers Squibb Investco LLC., E.R. Squibb & Sons, L.L.C., and Bristol-Myers Squibb Puerto Rico, Inc., subsidiaries of BMS, respectively, their partnership interests in the three partnerships carrying out the commercialization of Plavix ^® in the United States and Puerto Rico. As a consequence of these transactions, on February 28, 2020, Sanofi took sole control and freedom to operate commercially with respect to Plavix ^® in the United States and Puerto Rico. As from March 2020, Sanofi will recognize in its consolidated financial statements the revenue and expenses generated by its own operations.

On March 2, 2020, Sanofi announced that the U.S. Food and Drug Administration (FDA) has approved Sarclisa ^® (isatuximab-irfc) in combination with pomalidomide and dexamethasone (pom-dex) for the treatment of adults with relapsed refractory multiple myeloma (RRMM) who have received at least two prior therapies including lenalidomide and a proteasome inhibitor. Sarclisa ^® is expected to be available to patients in the U.S. shortly.

At its meeting on March 4, 2020, the Board of Directors of Sanofi decided to propose, at the next Annual General Meeting of Shareholders scheduled for April 28, 2020, the appointment of two new independent directors, Rachel Duan and Lise Kingo. Rachel Duan is currently Senior Vice President of GE and President & CEO of GE Global Markets, where she is responsible for driving GE's growth in China, Asia Pacific, India, the Middle East, Africa, and Latin America. Lise Kingo is currently CEO & Executive Director of the United Nations Global Compact, a position she has held since 2015. The UN Global Compact is the world’s largest corporate sustainability initiative uniting business to create a better world through universal principles and the UN Sustainable Development Goals. Lise Kingo will be stepping down from her post as CEO and Executive Director of the UN Global Compact in June 2020. Assuming election to the Board, she will not sit at Board meetings until she has separated from the United Nations.

ITEM 10. ADDITIONAL INFORMATION

Item 10. Additional Information

A. Share Capital

N/A

B. Memorandum and Articles of Association

General

Our Company is a société anonyme , a form of limited liability company, organized under the laws of France. The LEI number of the Company is 549300E9PC51EN656011.

In this section, we summarize material information concerning our share capital, together with material provisions of applicable French law and our Articles of Association ( statuts ), an English translation of which has been filed as an exhibit to this annual report. For a description of certain provisions of our Articles of Association relating to our Board of Directors and statutory auditors, see “Item 6. Directors, Senior Management and Employees.” You may obtain copies of our Articles of Association in French from the greffe (Clerk) of the Registre du Commerce et des Sociétés de Paris (Registry of Commerce and Companies of Paris, France, registration number: 395 030 844). Please refer to that full document for additional details.

Our Articles of Association specify that our corporate affairs are governed by:


▪	ap plicable laws and regulations (in particular, Title II of the French Commercial Code); and


▪	the Articl es of Association themselves.

Article 3 of our Articles of Association specifies that the Company’s corporate purpose, in France and abroad, is:

and, more generally:


▪	all commercial , industrial, real or personal property, financial or other transactions, connected directly or indirectly, totally or partially, with the activities described above and with all similar or related activities and even with any other purposes likely to encourage or develop the Company’s activities.

Directors

Transactions in which directors are materially interested

Under French law, any agreement entered into (directly or through an intermediary) between our Company and any one of the members of the Board of Directors that is not entered into (i) in the ordinary course of our business and (ii) under normal conditions is subject to the prior authorization of the disinterested members of the Board of Directors. The same provision applies to agreements between our Company and another company if one of the members of the Board of Directors is the owner, general partner, manager, director, general manager or member of the executive or supervisory board of the other company, as well as to agreements in which one of the members of the Board of Directors has an indirect interest.

The Board of Directors must also authorize any undertaking taken by our Company for the benefit of our Chairman, Chief Executive Officer ( directeur général ) or his delegates ( directeurs généraux délégués ) pursuant to which such persons will or may be granted compensation, benefits or any other advantages as a result of the termination of or a change in their offices or following such termination or change.

In addition, except with respect to any non-compete indemnity or certain pension benefits, any such termination package: (i) must be authorized by our shareholders through the adoption of a separate general shareholders meeting resolution for each such beneficiary, which authorization must be renewed at each renewal of such beneficiary’s mandate, and (ii) cannot be paid to such beneficiary unless (a) the Board of Directors decides that such beneficiary has satisfied certain conditions, linked to such beneficiary’s performance measured by our Company’s performance, that must have been defined by the Board of Directors when granting such package, and (b) such decision is publicly disclosed.

ITEM 10. ADDITIONAL INFORMATION

Directors’ compensation

The aggregate amount of attendance fees ( jetons de présence ) of the Board of Directors is determined at the Shareholders’ Ordinary General Meeting. The Board of Directors then divides this aggregate amount among its members by a simple majority vote. In addition, the Board of Directors may grant exceptional compensation ( rémunérations exceptionnelles ) to individual directors on a case-by-case basis for special assignments following the procedures described above at “- Transactions in Which Directors Are Materially Interested.” The Board of Directors may also authorize the reimbursement of travel and accommodation expenses, as well as other expenses incurred by Directors in the corporate interest. See also “Item 6. Directors, Senior Management and Employees.”

Board of Directors’ borrowing powers

All loans or borrowings on behalf of the Company may be decided by the Board of Directors within the limits, if any, imposed by the Shareholders’ General Meeting. There are currently no limits imposed on the amounts of loans or borrowings that the Board of Directors may approve.

Directors’ age limits

For a description of the provisions of our Articles of Association relating to age limits applicable to our Directors, see “Item 6. Directors, Senior Management and Employees.”

Directors’ share ownership requirements

Pursuant to the Board Charter, our Directors are required to hold at least 1,000 shares during the term of their appointment.

Share Capital

As of December 31, 2019 , our share capital amounted to €2,507,692,222, divided into 1,253,846,111 outstanding shares with a par value of €2 per share. All of our outstanding shares are of the same class and are fully paid. Of these shares, we or entities controlled by us held 19,481 shares (or 0.0015% of our outstanding share capital), as treasury shares as of such date. As of December 31, 2019 , the carrying amount of such shares was €1.1 million.

At an extraordinary general meeting held on April 30, 2019, our shareholders authorized our Board of Directors to increase our share capital, through the issuance of shares or other securities giving access to the share capital with or without preemptive rights, by an aggregate maximum nominal amount of €997 million. See “- Changes in Share Capital - Increases in Share Capital,” below.

The maximum total number of authorized but unissued shares as of December 31, 2019 was 134.73 million, reflecting the unused part of the April 30, 2019 shareholder authorizations to issue shares without preemptive rights, outstanding options to subscribe for shares, and awards of shares.

Stock Options

Types of stock options

We have two types of stock options outstanding: options to subscribe for shares ( options de souscription d’actions ) and options to purchase shares ( options d’achat d’actions ). Upon exercise of an option to subscribe for shares, we issue new shares, whereas upon exercise of an option to purchase shares, the option holder receives existing shares. We purchase our shares on the market prior to the vesting of the options to purchase in order to provide the option holder with shares upon exercise.

Because the exercise of options to purchase shares will be satisfied with existing shares repurchased on the market or held in treasury, the exercise of options to purchase shares has no impact on the amount of our share capital.

Stock option plans

Our combined general meeting held on April 30, 2019 authorized our Board of Directors for a period of 38 months to grant, on one or more occasions, options to subscribe for shares and options to purchase shares in favor of persons to be chosen by the Board of Directors from among the salaried employees and corporate officers of our Company or of companies or groupings of economic interest of the Group in accordance with Article L. 225-180 of the French Commercial Code.

The aggregate number of options to subscribe for shares and options to purchase shares that may be granted under this authorization may not give entitlement to a total number of shares exceeding 0.5% of the share capital as of the date of the decision by the Board of Directors to grant such options.

The Board of Directors sets the exercise price of options to subscribe for shares and options to purchase shares. However, the exercise price never incorporates a discount and must be at least equal (i) in the case of a grant of options to subscribe for shares, to the average of the quoted market prices of Sanofi's shares on the 20 trading sessions preceding the date of grant by the Board of Directors and (ii) in the case of a grant of options to purchase shares, either (a) the price indicated in (i) or (b) the average purchase price of shares held by Sanofi under Articles L. 225-208 and L. 225-209 of the French Commercial Code.

Stock option plans generally provide for a lock-up period of four years and have a duration of ten years.

Under such authorization the shareholders expressly waive, in favor of the grantees of options to subscribe for shares, their preemptive rights in respect of shares that are to be issued as and when options are exercised.

The Board of Directors is granted full power to implement this authorization and to set the terms and conditions on which options are granted and the arrangements with respect to the dividend entitlement of the shares.

See “Item 6. Directors, Senior Management and Employees - E. Share Ownership” for a description of our option plans currently in force.




SANOFI / FORM 20-F 2019	147

ITEM 10. ADDITIONAL INFORMATION

Awards of Shares

Our combined general meeting held on April 30, 2019 authorized our Board of Directors for a period of 38 months to allot, on one or more occasions, existing or new restricted shares in favor of persons to be chosen by the Board of Directors from among the salaried employees and corporate officers of our Company or of companies or economic interest groupings of the Group in accordance with Articles L. 225-197-1 et seq . of the French Commercial Code.

The existing or new shares allotted under this authorization may not represent more than 1.5% of our share capital as of the date of the decision by the Board of Directors to allot such shares.

The authorization provides that allotment of shares to the allottees will become irrevocable at the end of a minimum vesting period of three years.

In the case of newly issued shares, the authorization entails the express waiver by the shareholders, in favor of the allottees of restricted shares, of their preemptive rights in respect of shares that are to be issued as and when restricted shares vest.

The Board of Directors sets the terms on which restricted shares are granted and the arrangements with respect to the dividend entitlement of the shares.

See “Item 6. Directors, Senior Management and Employees - E. Share Ownership” for a description of our restricted shares plans currently in force.

Changes in Share Capital in 2019

See Note D.15.1. to our consolidated financial statements included at Item 18 of this annual report.

Voting Rights

In general, each shareholder is entitled to one vote per share at any shareholders’ general meeting. Our Articles of Association do not provide for cumulative voting rights. However, our Articles of Association provide that any fully paid-up shares that have been held in registered form under the name of the same shareholder for at least two years acquire double voting rights. The double voting rights cease automatically for any share converted into bearer form or transferred from one owner to another, subject to certain exceptions permitted by law.

As of December 31, 2019 , there were 152,376,825 shares that were entitled to double voting rights, representing 12.5% of our total share capital, and approximately 24.30% of the voting rights which can be cast at our shareholders’ general meeting as of that date.

Double voting rights are not taken into account in determining whether a quorum exists.

Under the French Commercial Code, treasury shares or shares held by entities controlled by that company are not entitled to voting rights and do not count for quorum purposes.

Our Articles of Association allow us to obtain from Euroclear France the name, nationality, address and number of shares held by holders of our securities that have, or may in the future have, voting rights. If we have reason to believe that a person on any list provided by Euroclear France holds securities on behalf of another person, our Articles of Association allow us to request information regarding beneficial ownership directly from such person. See “- B. Memorandum and Articles of Association - Form, Holding and Transfer of Shares,” below.

Our Articles of Association provide that Board members are elected on a rolling basis for a maximum tenure of four years.

Shareholders’ Agreement

We are not aware of any shareholder’s agreement currently in force concerning our shares.

Shareholders’ Meetings

General

In accordance with the provisions of the French Commercial Code, there are three types of shareholders’ meetings: ordinary, extraordinary and special.

Ordinary general meetings of shareholders are required for matters such as:


▪	electin g, replacing and removing Directors;

Special meetings of shareholders of a certain category of shares or shares with certain specific rights (such as shares with double voting rights) are required for any modification of the rights derived from that category of shares. The resolutions of the shareholders’ general meeting affecting these rights are effective only after approval by the relevant special meeting.

Annual ordinary meetings

The French Commercial Code requires the Board of Directors to convene an annual ordinary general shareholders’ meeting to approve the annual financial statements. This meeting must be held within six months of the end of each fiscal year. This period may be extended by an order of the President of the Commercial Court. The Board of Directors may also convene an ordinary or extraordinary general shareholders’ meeting upon proper notice at any time during the year. If the Board of Directors fails to convene a shareholders’ meeting, our independent auditors may call the meeting. In case of bankruptcy, the liquidator or court-appointed agent may also call a shareholders’ meeting in some instances. In addition, any of the following may request the court to appoint an agent for the purpose of calling a shareholders’ meeting:


▪	one or several shareholders holding at least 5% of our share capital;


▪	duly qualified associations of shareholders who have held their shares in registered form for at least two years and who together hold at least 1% of our voting rights;


▪	the works council in cases of urgency; or


▪	any intereste d party in cases of urgency.

Notice of shareholders’ meetings

All prior notice periods provided for below are minimum periods required by French law and cannot be shortened, except in case of a public tender offer for our shares.

We must announce general meetings at least thirty-five days in advance by means of a preliminary notice ( avis de réunion ), which is published in the Bulletin des Annonces Légales Obligatoires , or BALO . The preliminary notice must first be sent to the French Financial markets authority ( Autorité des marchés financiers , the “AMF”), with an indication of the date on which it will be published in the BALO . It must be published on our website at least twenty-one days prior to the general meeting. The preliminary notice must contain, among other things, the agenda, a draft of the resolutions to be submitted to the shareholders for consideration at the general meeting and a detailed description of the voting procedures (proxy voting, electronic voting or voting by mail), the procedures permitting shareholders to submit additional resolutions or items to the agenda and to ask written questions to the Board of Directors. The AMF also recommends that, prior to or simultaneously with the publication of the preliminary notice, we publish a summary of the notice indicating the date, time and place of the meeting in a newspaper of national circulation in France and on our website.

At least fifteen days prior to the date set for a first convening, and at least ten days prior to any second convening, we must send a final notice ( avis de convocation ) containing the final agenda, the date, time and place of the meeting and other information related to the meeting. Such final notice must be sent by mail to all registered shareholders who have held shares in registered form for more than one month prior to the date of the final notice and by registered mail, if shareholders have asked for it and paid the corresponding charges. The final notice must also be published in a newspaper authorized to publish legal announcements in the local administrative department ( département ) in which our Company is registered as well as in the BALO , with prior notice having been given to the AMF for informational purposes. Even if there are no proposals for new resolutions or items to be submitted to the shareholders at the meeting, we must publish a final notice in a newspaper authorized to publish legal announcements in the local administrative department ( département ) in which our Company is registered as well as in the BALO .

Other issues

In general, shareholders can only take action at shareholders’ meetings on matters listed on the agenda. As an exception to this rule, shareholders may take action with respect to the appointment and dismissal of directors even if this action has not been included on the agenda.

Additional resolutions to be submitted for approval by the shareholders at the shareholders’ meeting may be proposed to the Board of Directors, for recommendation to the shareholders at any time from the publication of the preliminary notice in the BALO until twenty-five days prior to the general meeting and in any case no later than twenty days following the publication of the preliminary notice in the BALO by:


▪	one or several shareholders together holding a specified percentage of shares;


▪	a duly qualified association of shareholders who have held their shares in registered form for at least two years and who together hold at least 1% of our voting rights; or


▪	the works council.

Within the same period, the shareholders may also propose additional items ( points ) to be submitted and discussed during the shareholders’ meeting, without a shareholders’ vote. The shareholders must substantiate the reasons for their proposals of additional items.

The resolutions and the list of items added to the agenda of the shareholders’ meeting must be promptly published on our website.




SANOFI / FORM 20-F 2019	149

ITEM 10. ADDITIONAL INFORMATION

In order to be counted, such proxies must be received at our registered office, or at any other address indicated on the notice of the meeting or by any electronic mail indicated on the notice of the meeting, prior to the date of the meeting (in practice, we request that shareholders return proxies at least three business days prior to the meeting; electronic proxies must be returned before 3 p.m. Paris time, on the day prior to the general meeting). A shareholder may grant proxies to any natural person or legal entity. The agent may be required to disclose certain information to the shareholder or to the public.

Alternatively, the shareholder may send us a blank proxy without nominating any representative. In this case, the chairman of the meeting will vote the blank proxies in favor of all resolutions proposed or approved by the Board of Directors and against all others.

With respect to votes by mail, we must send shareholders a voting form upon request or must make available a voting form on our website at least twenty-one days before the general meeting. The completed form must be returned to us at least three days prior to the date of the shareholders’ meeting. For holders of registered shares, in addition to traditional voting by mail, instructions may also be given via the internet.

Quorum

The French Commercial Code requires that shareholders holding in the aggregate at least 20% of the shares entitled to vote must be present in person, or vote by mail or by proxy, in order to fulfill the quorum requirement for:


▪	an or dinary general meeting; and


▪	an extra ordinary general meeting where the only resolutions pertain to either (a) a proposed increase in our share capital through incorporation of reserves, profits or share premium, or (b) the potential issuance of free share warrants in the event of a public tender offer for our shares (article L. 233-32 of the French Commercial Code).

For any other extraordinary general meeting the quorum requirement is at least 25% of the shares entitled to vote, held by shareholders present in person, voting by mail or by proxy.

For a special meeting of holders of a certain category of shares, the quorum requirement is one third of the shares entitled to vote in that category, held by shareholders present in person, voting by mail or by proxy.

If a quorum is not present at a meeting, the meeting is adjourned. However, only questions that were on the agenda of the adjourned meeting may be discussed and voted upon once the meeting resumes.

When an adjourned meeting is resumed, there is no quorum requirement for meetings cited in the first paragraph of this “ Quorum ” section. In the case of any other reconvened extraordinary general meeting or special meeting, the quorum requirement is 20% of the shares entitled to vote (or voting shares belonging to the relevant category for special meetings of holders of shares of such specific category), held by shareholders present in person or voting by mail or by proxy. If a quorum is not met, the reconvened meeting may be adjourned for a maximum of two months with the same quorum requirement. No deliberation or action by the shareholders may take place without a quorum.

Votes Required for Shareholder Action

The affirmative vote of a simple majority of the votes cast may pass a resolution at either an ordinary general meeting or an extraordinary general meeting where the only resolution(s) pertain(s) to either (a) a proposed increase in our share capital through incorporation of reserves, profits or share premium, or (b) the potential issuance of free share warrants in the event of a public tender offer for our shares (article L. 233-32 of the French Commercial Code). At any other extraordinary general shareholders’ meeting and at any special meeting of holders of




150	SANOFI / FORM 20-F 2019

ITEM 10. ADDITIONAL INFORMATION

a specific category of shares, the affirmative vote of two-thirds of the votes cast by those present or those represented by proxy or voting by mail is required.

As a result of a recent change in French law, as of the Annual General Meeting of April 28, 2020, abstention from voting, blank votes and null votes by those present or those represented by proxy or voting by mail are no longer counted as votes against the resolution submitted to a shareholder vote at any of the three types of meetings.

Changes to Shareholders’ Rights

Under French law, the affirmative vote of two-thirds of the votes cast at an extraordinary shareholders’ meeting is required to change our Articles of Association, which set out the rights attached to our shares, except for capital increases through incorporation of reserves, profits or share premium, or through the issuance of free share warrants in the event of a public tender offer for our shares (article L. 233-32 of the French Commercial Code).

The rights of a class of shareholders can be amended only after a special meeting of the class of shareholders affected has taken place. The voting requirements applicable to this type of special meeting are the same as those applicable to an extraordinary general shareholders’ meeting. The quorum requirements for a special meeting are one-third of the voting shares, or 20% upon resumption of an adjourned meeting.

A unanimous shareholders’ vote is required to increase the liabilities of shareholders.

Financial Statements and Other Communications with Shareholders

In connection with any shareholders’ meeting, we must provide a set of documents which includes our annual report.

We must also provide on our website at least twenty-one days before a shareholders’ meeting certain information and a set of documents that includes the preliminary notice, the proxies and voting forms, the resolutions proposed by the Board of Directors, and the documents to be submitted to the shareholders’ meeting pursuant to articles L. 225-115 and R. 225-83 of the French Commercial Code, etc. The resolutions and the list of items added to the agenda of the shareholders’ meeting must be promptly published on our website.

Dividends

We may only distribute dividends out of our “distributable profits,” plus any amounts held in our reserves that the shareholders decide to make available for distribution, other than those reserves that are specifically required by law or our Articles of Association. “Distributable profits” consist of our unconsolidated net profit in each fiscal year, as increased or reduced by any profit or loss carried forward from prior years, less any contributions to the reserve accounts pursuant to law or our Articles of Association.

Legal reserve

The French Commercial Code requires us to allocate 5% of our unconsolidated net profit for each year to our legal reserve fund before dividends may be paid with respect to that year. Funds must be allocated until the amount in the legal reserve is equal to 10% of the aggregate par value of the issued and outstanding share capital. This restriction on the payment of dividends also applies to each of our French subsidiaries on an unconsolidated basis. At December 31, 2019 , our legal reserve amounted to €282,280,863.40, representing 11.26% of the aggregate par value of our issued and outstanding share capital as of that date. The legal reserve of any company subject to this requirement may serve to allocate losses that may not be allocated to other reserves, or may be distributed to shareholders upon liquidation of the company.

Approval of dividends

According to the French Commercial Code, our Board of Directors may propose a dividend for approval by shareholders at the annual general shareholders’ meeting. If we have earned distributable profits since the end of the preceding fiscal year, as reflected in an interim income statement certified by our independent auditors, our Board of Directors may distribute interim dividends to the extent of the distributable profits for the period covered by the interim income statement. Our Board of Directors exercises this authority subject to French law and regulations and may do so without obtaining shareholder approval.

Distribution of dividends

Dividends are distributed to shareholders pro rata according to their respective holdings of shares. In the case of interim dividends, distributions are made to shareholders on the date set by our Board of Directors during the meeting in which the distribution of interim dividends is approved. The actual dividend payment date is decided by the shareholders at an ordinary general shareholders’ meeting or by our Board of Directors in the absence of such a decision by the shareholders. Shareholders that own shares on the actual payment date are entitled to the dividend.

Dividends may be paid in cash or, if the shareholders’ meeting so decides, in kind, provided that all shareholders receive a whole number of assets of the same nature paid in lieu of cash. Our Articles of Association provide that, subject to a decision of the shareholders’ meeting taken by ordinary resolution, each shareholder may be given the choice to receive his dividend in cash or in shares.

Timing of payment

According to the French Commercial Code, we must pay any existing dividends within nine months of the end of our fiscal year, unless otherwise authorized by court order. Dividends on shares that are not claimed within five years of the date of declared payment revert to the French State.

Changes in Share Capital

Increases in Share Capital

As provided for by the French Commercial Code, our share capital may be increased only with shareholders’ approval at an extraordinary general shareholders’ meeting following the recommendation of our Board of Directors. The shareholders may delegate to our Board of Directors either the authority (délégation de compétence) or the power (délégation de pouvoir) to carry out any increase in share capital. Our




SANOFI / FORM 20-F 2019	151

ITEM 10. ADDITIONAL INFORMATION

Board of Directors may further delegate this power to our Chief Executive Officer or, subject to our Chief Executive Officer’s approval, to his delegates (directeurs généraux délégués) .

Increases in our share capital may be effected by:


▪	issuing additional shares;


▪	increasing the par value of existing shares;


▪	creating a new class of equity securities; or


▪	exercising the rights attached to securities giving access to the share capital.

Increases in share capital by issuing additional securities may be effected through one or a combination of the following:


▪	in co nsideration for cash;


▪	in consideration for assets contributed in kind;


▪	through an exchange offer;


▪	by conversion of previously issued debt instruments;


▪	by capitalization of profits, reserves or share premium; or


▪	subject to variou s conditions, in satisfaction of debt incurred by our Company.

Decisions to increase the share capital through the capitalization of reserves, profits and/or share premium or through the issuance of free share warrants in the event of a public tender offer for our shares (article L. 233-32 of the French Commercial Code) require shareholders’ approval at an extraordinary general shareholders’ meeting, acting under the quorum and majority requirements applicable to ordinary shareholders’ meetings. Increases effected by an increase in the par value of shares require unanimous approval of the shareholders, unless effected by capitalization of reserves, profits or share premium. All other capital increases require shareholders’ approval at an extraordinary general shareholders’ meeting acting under the regular quorum and majority requirements for such meetings. See “- Quorum” and “- Votes Required for Shareholder Action” above.

On April 30, 2019, our shareholders approved various resolutions delegating to the Board of Directors the authority to increase our share capital through the issuance of shares or securities giving access to the share capital, subject to an overall cap set at €997 million. This cap applies to all the resolutions whereby the extraordinary shareholders’ meeting delegated to the Board of Directors the authority to increase the share capital, it being also specified that:


▪	the maxi mum aggregate par value of capital increases that may be carried out with preemptive rights maintained was set at €997 million;


▪	the maxim um aggregate par value of capital increases that may be carried out by public offering without preemptive rights was set at €240 million;


▪	the max i mum aggregate par value of capital increases that may be carried out by private placement without preemptive rights was set at €240 million;


▪	capital increases resulting in the issuance of securities to members of employee savings plans are limited to 1% of the share capital as computed on the date of the Board of Directors’ decision to issue such securities, and such issuances may be made at a discount of 30% (or 40%) if certain French law restrictions on resales were to apply, i.e. a lock up period of five years (or 10 years).

The Board of Directors did not make use of the delegation granted by the shareholders to carry out a capital increase reserved for members of the Group savings program in 2019.

As of December 31, 2019, the shares held by the company's employees or by employees of affiliated companies, as well as former employees in the Group savings programs represented 1.64% of the share capital.

Voting rights attached to shares held by FCPE Actions Sanofi are exercised individually by the employees who hold units in the fund; fractional rights are exercised by the fund’s supervisory board.

Voting rights attached to shares held by FCPE Sanofi Shares are also exercised individually by the employees who hold units in the fund; any rights not exercised by them are exercised by the fund’s supervisory board.

In each case, the supervisory board includes an equal number of representatives of employees and of Sanofi management.

On April 30, 2019, our shareholders approved resolutions delegating to the Board of Directors the authority to increase the share capital by granting options to our employees and/or corporate officers, subject to the overall cap mentioned above and under the following terms and conditions:


▪	the authorization is valid for a period of 38 months, and any options granted may not give entitlement to a total number of shares exceeding 0.5% of t h e share capital as computed on the date of the decision of the Board of Directors to grant such options; see “- Stock Options” above;

On April 30, 2019, our shareholders also approved resolutions delegating to the Board of Directors the authority to increase the share capital by granting existing or new restricted shares to our employees and/or corporate officers, subject to the overall cap mentioned above and under the following terms and conditions:




152	SANOFI / FORM 20-F 2019

ITEM 10. ADDITIONAL INFORMATION


▪	the authorization is valid for a period of 38 months, and is subject to a limit of 1.5% of the share capital as computed on the date of the decision of the Board of Directors to allot such shares; see “- Awards of Shares” above.

See also “Item 6. Directors, Senior Management and Employees - E. Share Ownership”.

Decreases in share capital

In accordance with the provisions of the French Commercial Code, any decrease in our share capital requires approval by the shareholders entitled to vote at an extraordinary general meeting. The share capital may be reduced either by decreasing the par value of the outstanding shares or by reducing the number of outstanding shares. The number of outstanding shares may be reduced either by an exchange of shares or by the repurchase and cancellation of shares. Holders of each class of shares must be treated equally unless each affected shareholder agrees otherwise.

In addition, specific rules exist to permit the cancellation of treasury shares, by which the shareholders’ meeting may authorize the cancellation of up to a maximum of 10% of a company’s share capital within any 24-month period. On April 30, 2019, our shareholders delegated to our Board of Directors for 26 months the right to reduce our share capital by canceling our own shares.

Preemptive Rights

According to the French Commercial Code, if we issue additional securities to be paid in cash, current shareholders will have preemptive rights to these securities on a pro rata basis. These preemptive rights require us to give priority treatment to current shareholders. The rights entitle the individual or entity that holds them to subscribe to the issuance of any securities that may increase the share capital of our Company by means of a cash payment or a set-off of cash debts. Preemptive rights are transferable during the subscription period relating to a particular offering. These rights may also be listed on Euronext Paris Stock Exchange.

Preemptive rights with respect to any particular offering may be waived by the affirmative vote of shareholders holding two-thirds of the shares entitled to vote at an extraordinary general meeting. Our Board of Directors and our independent auditors are required by French law to present reports that specifically address any proposal to waive preemptive rights. In the event of a waiver, the issuance of securities must be completed within the period prescribed by law. Shareholders may also notify us that they wish to waive their own preemptive rights with respect to any particular offering if they so choose.

The shareholders may decide at extraordinary general meetings to give the existing shareholders a non-transferable priority right to subscribe to the new securities, for a limited period of time.

In the event of a capital increase without preemptive rights to existing shareholders, French law requires that the capital increase be made at a price equal to or exceeding the weighted average market prices of the shares for the last three trading days on Euronext Paris Stock Exchange prior to the beginning of the public offering less 10%.

Form, Holding and Transfer of Shares

Form of shares

Our Articles of Association provide that the shares may be held in either bearer form or registered form at the option of the holder.

Holding of shares

In accordance with French law relating to the dematerialization of securities, shareholders’ ownership rights are represented by book entries instead of share certificates. We maintain a share account with Euroclear France (a French clearing system, which holds securities for its participants) for all shares in registered form, which is administered by BNP Paribas Securities Services. In addition, we maintain separate accounts in the name of each shareholder either directly or, at a shareholder’s request, through the shareholder’s accredited intermediary. Each shareholder account shows the name of the holder and the number of shares held. BNP Paribas Securities Services issues confirmations ( attestations d’inscription en compte ) to each registered shareholder as to shares registered in the shareholder’s account, but these confirmations are not documents of title.

Shares of a listed company may also be issued in bearer form. Shares held in bearer form are held and registered on the shareholder’s behalf in an account maintained by an accredited financial intermediary and are credited to an account at Euroclear France maintained by such intermediary. Each accredited financial intermediary maintains a record of shares held through it and provides the account holder with a securities account statement. Transfers of shares held in bearer form may only be made through accredited financial intermediaries and Euroclear France.

Shares held by persons who are not domiciled in France may be registered in the name of intermediaries who act on behalf of one or more investors. When shares are so held, we are entitled to request from such intermediaries the names of the investors. Also, we may request any legal entity ( personne morale ) which holds more than 2.5% of our shares or voting rights to disclose the name of any person who owns, directly or indirectly, more than one-third of its share capital or of its voting rights. A person not providing the complete requested information in time, or who provides incomplete or false information, will be deprived of its voting rights at shareholders’ meetings and will have its payment of dividends withheld until it has provided the requested information in strict compliance with French law. If such person acted willfully, the person may be deprived by a French court of either its voting rights or its dividends or both for a period of up to five years.

Transfer of shares

Our Articles of Association do not contain any restrictions relating to the transfer of shares.

Registered shares must be converted into bearer form before being transferred on the Euronext Paris Stock Exchange on the shareholders’ behalf and, accordingly, must be registered in an account maintained by an accredited financial intermediary on the shareholders’ behalf. A shareholder may initiate a transfer by giving instructions to the relevant accredited financial intermediary.




SANOFI / FORM 20-F 2019	153

ITEM 10. ADDITIONAL INFORMATION

A fee or commission is payable to the broker involved in the transaction, regardless of whether the transaction occurs within or outside France. Registration duty is currently payable in France if a written deed of sale and purchase ( acte ) is executed in France or outside France with respect to the shares of the Company.

Redemption of Shares

Under French law, our Board of Directors is entitled to redeem a set number of shares as authorized by the extraordinary shareholders’ meeting. In the case of such an authorization, the shares redeemed must be cancelled within one month after the end of the offer to purchase such shares from shareholders. However, shares redeemed on the open market do not need to be cancelled if the company redeeming the shares grants options on or awards those shares to its employees within one year following the acquisition. See also “- Trading in Our Own Shares” below.

Sinking Fund Provisions

Our Articles of Association do not provide for any sinking fund provisions.

Liability to Further Capital Calls

Shareholders are liable for corporate liabilities only up to the par value of the shares they hold; they are not liable to further capital calls.

Liquidation Rights

If we are liquidated, any assets remaining after payment of our debts, liquidation expenses and all of our remaining obligations will first be distributed to repay in full the par value of our shares. Any surplus will be distributed pro rata among shareholders in proportion to the par value of their shareholdings.

Requirements for Holdings Exceeding Certain Percentages

The French Commercial Code provides that any individual or entity, acting alone or in concert with others, that becomes the owner, directly or indirectly, of more than 5%, 10%, 15%, 20%, 25%, 30%, 33 ¹ / ₃ %, 50%, 66 ² / ₃ %, 90% or 95% of the outstanding shares or voting rights of a listed company in France, such as our Company, or that increases or decreases its shareholding or voting rights above or below any of those percentages, must notify the company, before the end of the fourth trading day following the date it crosses the threshold, of the number of shares it holds and their voting rights. The individual or entity must also notify the AMF before the end of the fourth trading day following the date it crosses any such threshold. The AMF makes the notice public.

Pursuant to the French Commercial Code and the AMF General Regulation, the participation thresholds shall be calculated on the basis of the shares and voting rights owned, and shall take into account the shares and voting rights which are deemed to be shares and voting rights owned, even if the individual or entity does not itself hold shares or voting rights. In accordance with this deemed ownership principle, the individual or entity must take into account specific situations where shares and voting rights are deemed to be shares and voting rights owned when calculating the number of shares owned to be disclosed in the notifications to the Company and to the AMF. It includes among others situations where an individual or entity is entitled to acquire issued shares at its own initiative, immediately or at the end of a maturity period, under an agreement or a financial instrument, without set-off against the number of shares that this individual or entity is entitled to sell under another agreement or financial instrument. The individual or entity required to make such notification shall also take into account issued shares covered by an agreement or cash-settled financial instrument and having an economic effect for said individual or entity that is equivalent to owning such shares. In the cases of deemed ownership described above, the notification shall mention the type of deemed ownership and include a description of the main characteristics of the financial instrument or agreement with specific details required by the AMF General Regulation.

The AMF General Regulation provides that shares and voting rights subject to multiple cases of deemed ownership shall only be counted once.

When an individual or entity modifies the allocation between the shares it owns and its financial instruments or agreements deemed to be owned shares, it must disclose that change in a new notification. However, the change must only be disclosed if the acquisition of owned shares due to the settlement of the financial instruments or agreements causes the investor to cross a threshold.

Subject to certain limited exceptions, French law and AMF regulations impose additional reporting requirements on persons who acquire more than 10%, 15%, 20%, or 25% of the outstanding shares or voting rights of a company listed in France. These persons must file a report with the company and the AMF before the end of the fifth trading day following the date they cross any such threshold.

In the report, the acquirer will have to specify its intentions for the following six months including:


▪	wheth er it acts alone or in concert with others;


▪	the means of financing of the acquisition (the notifier shall indicate in particular whether the acquisition is being financed with equity or debt, the main features of that debt, and, where applicable, the main guarantees given or received by the notifier. The notifier shall also indicate what portion of its holding, if any, it obtained through securities loans);


▪	whether or not it intends to continue its purchases;


▪	whether or not it intends to acquire control of the company in question;


▪	the strategy it contemplates vis-à-vis the issuer;

▪

the way it intends to implement its strategy, including: (i) any plans for a merger, reorganization, liquidation, or partial transfer of a substantial part of the assets of the issuer or of any other entity it controls within the meaning of article L. 233-3 of the French Commercial Code, (ii) any plans to modify the business of the issuer, (iii) any plans to modify articles of association of the issuer, (iv) any plans to delist a category of the issuer’s financial instruments, and (v) any plans to issue the issuer’s financial instruments;


▪	any agreement for the temporary transfer of shares or voting rights of the issuer;




154	SANOFI / FORM 20-F 2019

ITEM 10. ADDITIONAL INFORMATION


▪	the way it intends to settle its agreements or instruments on the shares or voting rights of the issuer mentioned in Article L. 233- 9,4° and 4° bis of the French Commercial Code; and


▪	whether it seeks repr esentation on the Board of Directors.

The AMF makes the report public. Upon any change of intention within the six-month period following the filing of the report, it will have to file a new report for the following six-month period.

In order to enable shareholders to give the required notice, we must each month publish on our website and send the AMF a written notice setting forth the total number of our shares and voting rights (including treasury shares) whenever they vary from the figures previously published.

If any shareholder fails to comply with an applicable legal notification requirement, the shares in excess of the relevant threshold will be deprived of voting rights for all shareholders’ meetings until the end of a two-year period following the date on which the owner complies with the notification requirements. In addition, any shareholder who fails to comply with these requirements may have all or part of its voting rights suspended for up to five years by the Commercial Court at the request of our Chairman, any shareholder or the AMF, and may be subject to criminal fines.

Under AMF regulations, and subject to limited exemptions granted by the AMF, any person or entity, acting alone or in concert, that crosses the threshold of 30% of the share capital or voting rights of a French listed company must initiate a public tender offer for the balance of the shares and securities giving access to the share capital or voting rights of such company. Cash-settled derivative instruments or agreements mentioned in Article L. 233-9, 4° bis of the French Commercial Code are not included in the calculation of the number of shares related to the mandatory public tender offer.

In addition, our Articles of Association provide that any person or entity, acting alone or in concert with others, who becomes the owner of 1%, or any multiple of 1% of our share capital or our voting rights, even beyond the minimum declaration limits permitted by the legal and regulatory provisions, must notify us by certified mail, return receipt requested, within five trading days, of the total number of shares and securities giving access to our share capital and voting rights that such person then owns. The same provisions of our Articles of Association apply whenever such owner increases or decreases its ownership of our share capital or our voting rights to such extent that it goes above or below one of the thresholds described in the preceding sentence. Any person or entity that fails to comply with such notification requirement will, upon the request of one or more shareholders holding at least 5% of our share capital or of our voting rights made at the general shareholders’ meeting, be deprived of voting rights with respect to the shares in excess of the relevant threshold for all shareholders’ meetings until the end of a two-year period following the date on which such person or entity complies with the notification requirements.

Change in Control/Anti-Takeover

There are no provisions in our Articles of Association that would have the effect of delaying, deferring or preventing a change in control of our Company or that would operate only with respect to a merger, acquisition or corporate restructuring involving our Company or any of our subsidiaries. Further, there are no provisions in our Articles of Association that allow the issuance of preferred stock upon the occurrence of a takeover attempt or the addition of other “anti-takeover” measures without a shareholder vote.

Our Articles of Association do not include any provisions discriminating against any existing or prospective holder of our securities as a result of such shareholder owning a substantial number of shares.

Trading in our Own Shares

Under French law, Sanofi may not issue shares to itself. However, we may, either directly or through a financial intermediary acting on our behalf, acquire up to 10% of our issued share capital within a maximum period of 18 months, provided our shares are listed on a regulated market. Prior to acquiring our shares, we must publish a description of the share repurchase program ( descriptif du programme de rachat d’actions ).

We may not cancel more than 10% of our issued share capital over any 24-month period. Our repurchase of shares must not result in our Company holding, directly or through a person acting on our behalf, more than 10% of our issued share capital. We must hold any shares that we repurchase in registered form. These shares must be fully paid up. Shares repurchased by us continue to be deemed “issued” under French law but are not entitled to dividends or voting rights so long as we hold them directly or indirectly, and we may not exercise the preemptive rights attached to them.

The shareholders, at an extraordinary general shareholders meeting, may decide not to take these shares into account in determining the preemptive rights attached to the other shares. However, if the shareholders decide to take them into account, we must either sell the rights attached to the shares we hold on the market before the end of the subscription period or distribute them to the other shareholders on a pro rata basis.

On May 2, 2018 and on April 30, 2019, our shareholders successively approved a resolution authorizing us to repurchase up to 10% of our shares over an 18-month period. Under this authorization, the purchase price for each Sanofi ordinary share may not be greater than €120.00 and the maximum amount that Sanofi may pay for the repurchases is €14,968,745,640. This authorization was granted for a period of 18 months from April 30, 2019 and cancelled and replaced the authorization granted to the Board of Directors by the combined general meeting held on May 2, 2018. A description of this share repurchase program as adopted by the combined general meeting held on April 30, 2019 ( descriptif du programme de rachat d’actions ) was published on March 8, 2019.

Purposes of Share Repurchase Programs

Under the European regulation 596/2014, dated April 16, 2014 on market abuse and its delegated regulation 2016/1052 on repurchase programs and stabilization measures, dated March 8, 2016 (which we refer to in this section as the “Regulation”), an issuer will benefit from a safe harbor for share transactions that comply with certain conditions relating in particular to the pricing, volume and timing of transactions (see below) and that are made in connection with a share repurchase program the purpose of which is:


▪	to red uce the share capital through the cancellation of treasury shares;




SANOFI / FORM 20-F 2019	155

ITEM 10. ADDITIONAL INFORMATION


▪	to meet obligations arising from debt financial instruments that are exchangeable into equity instruments; and/or


▪	to meet o bligations arising from share option programs or other allocations of shares to employees or to members of the administrative, management or supervisory bodies of the issuer or of an associate company.

Safe harbor transactions will by definition not be considered market abuses under the Regulation. Transactions that are carried out for other purposes than those mentioned above do not qualify for the safe harbor.

However, as permitted by the Regulation, which provides for a presumption of legitimacy for existing market practices that do not constitute market manipulation and that conform with certain criteria, the AMF has established as a French accepted market practice, which therefore benefits from a presumption of legitimacy, the use of liquidity agreements for share purchases that are entered into with a financial services intermediary and that comply with the criteria set out by the AMF.

The AMF confirmed that all transactions directed at maintaining the liquidity of an issuer’s shares must be conducted pursuant to a liquidity agreement with a financial services intermediary acting independently.

As of July 3, 2016, the purchase of shares that are subsequently used as acquisition currency in a business combination transaction, which the AMF previously permitted as an accepted market practice, is no longer considered as such, although such practice, while not benefiting from the presumption of legitimacy, is not prohibited under the Regulation.

Pricing, Volume and Other Restrictions

In order to qualify for the safe harbor described above, the issuer must generally comply with the following pricing and volume restrictions:


▪	a share purc hase must not be made at a price higher than the higher of the price of the last independent trade and the highest current independent bid on the trading venues where the purchase is carried out; and

▪

subject to certai n exceptions for illiquid securities, the issuer must not purchase on any trading day more than 25% of the average daily volume of the shares on the regulated market on which the purchase is carried out. The average daily volume figure must be based on the average daily volume traded in the month preceding the month of public disclosure of the share repurchase program and fixed on that basis for the authorized period of that program. If the program does not make reference to this volume, the average daily volume figure must be based on the average daily volume traded in the 20 trading days preceding the date of purchase.

In addition, unless the issuer has in place a time-scheduled repurchase program or the repurchase program is lead-managed by an investment firm or a credit institution which makes its trading decisions concerning the timing of the purchase of the issuer’s shares independently of the issuer, the issuer must not, for the duration of the repurchase program, engage in the following activities:


▪	selli ng its own shares;

▪

effecting any transaction during a closed period imposed by the applicable law of the Member State in which the transaction occurs (i.e. under French law, during the period between the date on which the company has knowledge of insider information and the date on which such information is made public and during the 30 calendar day period before the announcement of an interim financial report or a year-end report which the issuer is obliged to make public); or


▪	effecting a ny transaction in securities with respect to which the issuer has decided to delay the public disclosure of inside information, in accordance with applicable rules.

Use of Share Repurchase Programs

Pursuant to the AMF rules, issuers must immediately allocate the repurchased shares to one of the purposes provided for in the Regulation and must not subsequently use the shares for a different purpose. As an exception to the foregoing, shares repurchased with a view to covering stock option plans may, if no longer needed for this purpose, be re-allocated for cancellation or sold in compliance with AMF requirements relating in particular to blackout periods. Shares repurchased in connection with one of the market practices authorized by the AMF (see above) may also be re-allocated to one of the purposes contemplated by the Regulation or sold in compliance with AMF requirements. Shares repurchased with a view to their cancellation must be cancelled within 24 months following their acquisition.

During the year ended December 31, 2019 , we used the authority delegated by our shareholders to repurchase our shares on the stock market.

Pursuant to our share repurchase programs authorized by our shareholders on May 2, 2018 and on April 30, 2019, we repurchased 272,383 of our shares for a weighted average price of €76.97, i.e. a total cost of €21 million. Brokerage fees and financial transaction taxes (net of income taxes) amounted to €0.03 million. Our Company did not resort to derivatives to repurchase our own shares.

During 2019 , pursuant to the liquidity contract, Rothschild & Cie:


▪	purcha sed 124,590 of our shares at an average weighted price of €74.35 for a total amount of €9,262,734; and


▪	sold 124,590 of our shares at an average weighted price of €74.35 for a total amount of €9,262,734.

In 2019 , of the 104,701 shares allocated to stock purchase option plans outstanding at December 31, 2018 , 70,270 shares were transferred to grantees of options and 10,401 shares were allocated to the covering of performance share plans.

In 2019 , in addition to the 1,860,416 shares allocated to restricted share plans outstanding at December 31, 2018 , Sanofi:


▪	purchas ed 147,793 of its shares at an average weighted price of €79.18 for a total amount of €11,701,792; and

ITEM 10. ADDITIONAL INFORMATION

The liquidity contracted entered into between Sanofi and Rothschild Martin Maurel was terminated on February 15, 2019.

As of December 31, 2019 , all of our 19,481 treasury shares, representing 0.002% of our share capital, were allocated to outstanding performance share plans. At the same date, none of the shares was allocated to the covering of a stock-option plan or the liquidity account or for the purpose of cancellation.

As of December 31, 2019 , we directly owned 19,481 Sanofi shares with a par value of €2 representing around 0.002% of our share capital and with an estimated value of €1 million, based on the share price at the time of purchase.

Reporting Obligations

Pursuant to the Regulation, the AMF Regulation and the French Commercial Code, issuers trading in their own shares are subject to the following reporting obligations:


▪	issu ers must report all transactions in their own shares to the competent authority of each trading venue on which the shares are admitted to trading or are traded within seven trading days of the transaction in a prescribed format, unless such transactions are carried out pursuant to a liquidity agreement that complies with the ethical code approved by the AMF;


▪	issuers must declare to the AMF on a monthly basis all transactions completed under the share repurchase program unless they provide the same information on a weekly basis; and


▪	post on its website the transactions disclosed and keep that information available to the public for at least a 5-year period from the date of public disclosure.

Ownership of Shares by Non-French Persons

The French Commercial Code and our Articles of Association currently do not limit the right of non-residents of France or non-French persons to own or, where applicable, to vote our securities. However, non-residents of France must file an administrative notice with the French authorities in connection with certain direct and indirect investments in us, including the acquisition of a controlling interest in our Company. Under existing administrative rulings, ownership of 33 ¹ / ₃ % or more of our share capital or voting rights is regarded as a controlling interest, but a lower percentage might be held to be a controlling interest in certain circumstances depending upon factors such as:


▪	the ac quiring party’s intentions;


▪	the acquiring party’s ability to elect directors; or


▪	financial rel iance by the company on the acquiring party.

Moreover, certain foreign investments in companies incorporated under French laws are subject to prior authorization from the French Minister of the Economy, where all or part of the target’s business and activity relate to a strategic sector, such as energy, transportation, public health, telecommunications, etc.

Enforceability of Civil Liabilities

We are a limited liability company ( société anonyme ) organized under the laws of France, and most of our officers and directors reside outside the United States. In addition, a substantial portion of our assets is located in France.

As a result, it may be difficult for investors:


▪	to obt ain jurisdiction over us or our non-US resident officers and directors in US courts, or obtain evidence in France or from French persons, in connection with those actions in actions predicated on the civil liability provisions of the US federal securities laws;


▪	to enforce in US courts judgments obtained in such actions against us or our non-US resident officers and directors;


▪	to bring an original action in a French court to enforce liabilities based upon the US federal securities laws against us or our non-US resident officers or directors; and


▪	to enforce in US courts a gainst us or our directors in non-US courts, including French courts, judgments of US courts predicated upon the civil liability provisions of the US federal securities laws.

Nevertheless, a final judgment for the payment of money rendered by any federal or state court in the United States based on civil liability, whether or not predicated solely upon the US federal securities laws, would be recognized and enforced in France provided that a French judge considers that this judgment meets the French legal requirement concerning the recognition and the enforcement of foreign judgments and is capable of being immediately enforced in the United States. A French court is therefore likely to grant the enforcement of a foreign judgment without a review of the merits of the underlying claim, only if (1) that judgment resulted from legal proceedings compatible with French standards of due process, (2) the judgment does not contravene international public order and public policy of France and (3) the jurisdiction of the US federal or state court has been based on principles of French private international law. The French court would also require that the US judgment is not tainted with fraud and is not incompatible with a judgment rendered by a French court in the same matter, or with an earlier judgment rendered by a foreign court in the same matter.

In addition, French law guarantees full compensation for the harm suffered but is limited to the actual damages, so the the victim does not suffer or benefit from the situation. Such system excludes damages such as, but not limited to, punitive and exemplary damages.

As a result, the enforcement, by US investors, of any judgments obtained in US courts in civil and commercial matters, including judgments under the US federal securities law against us or members of our Board of Directors, officers or certain experts named herein who are residents of France or countries other than the United States would be subject to the above conditions.




SANOFI / FORM 20-F 2019	157

ITEM 10. ADDITIONAL INFORMATION

Finally, there may be doubt as to whether a French court would impose civil liability on us, the members of our Board of Directors, our officers or certain experts named herein in an original action predicated solely upon the US federal securities laws brought in a court of competent jurisdiction in France against us or such members, officers or experts, respectively.

C. Material Contracts

The contingent value rights agreement

In connection with its acquisition of Genzyme Corporation, now a wholly-owned subsidiary of Sanofi, Sanofi issued one CVR per Genzyme share. On March 30, 2011, Sanofi and American Stock Transfer & Trust Company, LLC (“AST”), as trustee, entered into a Contingent Value Rights Agreement (the “CVR Agreement”) governing the terms of the CVRs. On May 13, 2016, AST tendered its resignation as trustee under the CVR Agreement to Sanofi. As of June 30, 2016, UMB Bank, National Association replaced AST and is the successor trustee under the CVR Agreement.

Pursuant to the terms of the CVR Agreement, a holder of a CVR is entitled to cash payments upon the achievement of contractually defined milestones. The first three milestones (related, respectively, to (i) manufacturing of Cerezyme ^® and Fabrazyme ^® (ii) US regulatory approval on or before March 31, 2014 of Lemtrada ^® for the treatment of MS (the “Approval Milestone”) and (iii) Product Sales Milestone #1, pursuant to which a holder of a CVR would have been entitled to receive $2 per CVR if Lemtrada ^® sales (as defined in the CVR Agreement) post launch equaled or exceeded a total of $400 million within certain specified periods and territories) were not met. The remaining milestone payments under the CVR Agreement are summarized below:

Product Sales Milestone #2 Payment. $3 per CVR upon the first instance in which Lemtrada ^® sales (as defined in the CVR Agreement) for a four calendar quarter period are equal to or in excess of $1.8 billion. Given that the Approval Milestone was not achieved, an additional $1 per CVR will be paid should Product Sales Milestone #2 be achieved, totaling $4 per CVR.

Product Sales Milestone #3 Payment. $4 per CVR upon the first instance in which Lemtrada ^® sales (as defined in the CVR Agreement) for a four calendar quarter period are equal to or in excess of $2.3 billion (however, no quarter in which Lemtrada ^® sales (as defined in the CVR Agreement) were used to determine the achievement of Product Sales Milestone #1 or #2 shall be included in the calculation of sales for determining whether Product Sales Milestone #3 has been achieved).

Product Sales Milestone #4 Payment. $3 per CVR upon the first instance in which Lemtrada ^® sales (as defined in the CVR Agreement) for a four calendar quarter period are equal to or in excess of $2.8 billion (however, no quarter in which Lemtrada ^® sales (as defined in the CVR Agreement) were used to determine the achievement of Product Sales Milestone #1, #2 or #3 shall be included in the calculation of sales for determining whether Product Sales Milestone #4 has been achieved).

On February 7, 2018, Sanofi disclosed that, based upon actual sales trends to date, it does not expect that product sales milestones #2 to #4 will be met.

The CVR Agreement will terminate on the earlier of (a) December 31, 2020 and (b) the date that Product Sales Milestone #4 is paid (the “Termination Date”), provided that if any milestone has been achieved prior to the Termination Date, but the associated CVR payment has not been paid on or prior to the Termination Date, the CVR Agreement shall not terminate until such payment has been paid in full in accordance with the terms of the CVR Agreement.

Sanofi has agreed to use diligent efforts (as defined in the CVR Agreement), until the CVR Agreement is terminated, to achieve each of the remaining milestones. However, we are not required to take all possible actions to achieve these goals. Sanofi has also agreed to use its commercially reasonable efforts to maintain a listing for trading of the CVRs on the NASDAQ market.

For more information on Lemtrada ^® see “Item 4.B Business Overview - Pharmaceutical Products - Multiple Sclerosis”.

The CVR Agreement does not prohibit Sanofi or any of its subsidiaries or affiliates (as defined in the CVR Agreement) from acquiring the CVRs, whether in open market transactions, private transactions or otherwise. Sanofi has certain disclosure obligations in connection with such acquisitions under the CVR Agreement. Sanofi may also, subject to certain terms and conditions as set forth in the CVR Agreement, optionally purchase and cancel all (but not less than all) of the outstanding CVRs at a cash price as set forth in the CVR Agreement if (i) the volume-weighted average price paid per CVR for all CVRs traded over the forty-five trading days prior to such date is less than fifty cents and (ii) Lemtrada ^® sales (as defined in the CVR Agreement) in the four calendar quarters ended immediately prior to such date are less than $1 billion in the aggregate.

A copy of the form of CVR Agreement is on file with the SEC as Annex B to Amendment No. 2 to the Registration Statement on Form F-4 filed with the Securities and Exchange Commission on March 24, 2011. Reference is made to such exhibit for a more complete description of the terms and conditions of the CVR Agreement, and the foregoing summary of such terms and conditions is qualified in its entirety by such exhibit. Reference is also made to Sanofi’s Form 6-K filed on October 31, 2019, in which Sanofi disclosed an agreement to settle litigation involving claims against Sanofi for breach of the CVR Agreement. Among other things, the settlement agreement provides that the CVRs will be delisted from the NASDAQ and extinguished, and the CVR Agreement will be terminated. This is only a summary of certain of the terms of the settlement agreement and is qualified in its entirety by the terms thereof. The settlement agreement was attached as an exhibit to Sanofi’s October 31, 2019 Form 6-K .

D. Exchange Controls

French exchange control regulations currently do not limit the amount of payments that we may remit to non-residents of France. Laws and regulations concerning foreign exchange controls do require, however, that all payments or transfers of funds made by a French resident to a non-resident be handled by an accredited intermediary.

ITEM 10. ADDITIONAL INFORMATION

E. Taxation

General

The following generally summarizes the material French and US federal income tax consequences to US holders (as defined below) of purchasing, owning and disposing of our ADSs and ordinary shares (collectively the “Securities”). This discussion is intended only as a descriptive summary and does not purport to be a complete analysis or listing of all potential tax effects of the purchase, ownership or disposition of our Securities. All of the following is subject to change. Such changes could apply retroactively and could affect the consequences described below.

This summary does not constitute a legal opinion or tax advice. Holders are urged to consult their own tax advisers regarding the tax consequences of the purchase, ownership and disposition of Securities in light of their particular circumstances, including the effect of any US federal, state, local or other national tax laws.

A set of tax rules is applicable to French assets that are held by or in foreign trusts. These rules provide inter alia for the inclusion of trust assets in the settlor’s net assets for purpose of applying the French real estate wealth tax, for the application of French gift and death duties to French assets held in trust, for a specific tax on capital on the French assets of foreign trusts not already subject to the French real estate wealth tax and for a number of French tax reporting and disclosure obligations. The following discussion does not address the French tax consequences applicable to Securities held in trusts. If Securities are held in trust, the grantor, trustee and beneficiary are urged to consult their own tax adviser regarding the specific tax consequences of acquiring, owning and disposing of Securities.

The description of the French and US federal income tax consequences set forth below is based on the laws (including, for US federal income tax purposes, the Internal Revenue Code of 1986, as amended (the “Code”), final, temporary and proposed US Treasury Regulations promulgated thereunder and administrative and judicial interpretations thereof) in force as of the date of this annual report, the Convention Between the Government of the United States of America and the Government of the French Republic for the Avoidance of Double Taxation and the Prevention of Fiscal Evasion with Respect to Taxes on Income and Capital of August 31, 1994 (the “Treaty”), which entered into force on December 30, 1995 (as amended by any subsequent protocols, including the protocol of January 13, 2009), and the tax regulations issued by the French tax authorities within the Bulletin Officiel des Finances Publiques-Impôts (the “Regulations”) in force as of the date of this report. US holders are advised to consult their own tax advisers regarding their eligibility for Treaty benefits, especially with regard to the “Limitations on Benefits” provision, in light of their own particular circumstances.

For the purposes of this discussion, a US holder is a beneficial owner of Securities that is (i) an individual who is a US citizen or resident for US federal income tax purposes, (ii) a US domestic corporation or certain other entities created or organized in or under the laws of the United States or any state thereof, including the District of Columbia, or (iii) otherwise subject to US federal income taxation on a net income basis in respect of Securities. A non-US holder is a person other than a US holder.

If a partnership holds Securities, the tax treatment of a partner generally will depend upon the status of the partner and the activities of the partnership. If a US holder is a partner in a partnership that holds Securities, the holder is urged to consult its own tax adviser regarding the specific tax consequences of acquiring, owning and disposing of Securities.

This discussion is intended only as a general summary and does not purport to be a complete analysis or listing of all potential tax effects of the acquisition, ownership or disposition of the Securities to any particular investor, and does not discuss tax considerations that arise from rules of general application or that are generally assumed to be known by investors. The discussion applies only to investors that hold our Securities as capital assets that have the US dollar as their functional currency, that are entitled to Treaty benefits under the “Limitation on Benefits” provision contained in the Treaty, and whose ownership of the Securities is not effectively connected to a permanent establishment or a fixed base in France. Certain holders (including, but not limited to, US expatriates, partnerships or other entities classified as partnerships for US federal income tax purposes, banks, insurance companies, regulated investment companies, tax-exempt organizations, financial institutions, persons subject to the alternative minimum tax, persons who acquired the Securities pursuant to the exercise of employee stock options or otherwise as compensation, persons that own (directly, indirectly or by attribution) 5% or more of our voting stock or 5% or more of our outstanding share capital, dealers in securities or currencies, persons that elect to mark their securities to market for US federal income tax purposes, persons that acquire ADSs in “pre-release” transactions (i.e. prior to deposit of the relevant ordinary shares, although our depositary has indicated that such transactions have been halted) and persons holding Securities as a position in a synthetic security, straddle or conversion transaction) may be subject to special rules not discussed below. Holders of Securities are advised to consult their own tax advisers with regard to the application of French tax law and US federal income tax law to their particular situations, as well as any tax consequences arising under the laws of any state, local or other foreign jurisdiction.

French Taxes

Estate and gift taxes and transfer taxes

In general, a transfer of Securities by gift or by reason of death of a US holder that would otherwise be subject to French gift or inheritance tax, respectively, will not be subject to such French tax by reason of the Convention between the Government of the United States of America and the Government of the French Republic for the Avoidance of Double Taxation and the Prevention of Fiscal Evasion with Respect to Taxes on Estates, Inheritances and Gifts, dated November 24, 1978, unless the donor or the transferor is domiciled in France at the time of making the gift or at the time of his or her death, or the Securities were used in, or held for use in, the conduct of a business through a permanent establishment or a fixed base in France.

Pursuant to Article 235 ter ZD of the French General Tax Code, purchases of Securities are subject to a 0.3% French tax on financial transactions (the “FTFF”) provided that Sanofi’s market capitalization exceeds 1 billion euros as of December 1 of the year preceding the taxation year. A list of companies whose market capitalization exceeds 1 billion euros as of December 1 of the year preceding the taxation year used to be published annually by the French Ministry of Economy. It is now published by the French tax authorities, and could be amended at any time. Pursuant to Regulations BOI-ANNX-000467-201912187 issued on December 18, 2019, purchases of Sanofi’s Securities in 2020 should be subject to the FTFF as the market capitalization of Sanofi exceeded 1 billion euros as of December 1, 2019. In accordance with Article 726-II-d of the French General Tax Code, purchases which are subject to the FTFF should however not be subject to transfer taxes ( droits d’enregistrement ) in France.




SANOFI / FORM 20-F 2019	159

ITEM 10. ADDITIONAL INFORMATION

Wealth Tax

The French wealth tax ( impôt de solidarité sur la fortune ) has been replaced with a French real estate wealth tax (impôt sur la fortune immobilière) with effect from January 1, 2018. French real estate wealth tax applies only to individuals and does not generally apply to the Securities if the holder is a US resident, as defined pursuant to the provisions of the Treaty, provided that the individual does not own directly or indirectly a shareholding exceeding 10% of the financial rights and voting rights.

US Taxes

Ownership of the securities

Deposits and withdrawals by a US holder of ordinary shares in exchange for ADSs, will not be taxable events for US federal income tax purposes. For US tax purposes, holders of ADSs will be treated as owners of the ordinary shares represented by such ADSs. Accordingly, the discussion that follows regarding the US federal income tax consequences of acquiring, owning and disposing of ordinary shares is equally applicable to ADSs.

Information reporting and backup withholding tax

Distributions made to holders and proceeds paid from the sale, exchange, redemption or disposal of Securities may be subject to information reporting to the Internal Revenue Service. Such payments may be subject to backup withholding taxes unless the holder (i) is a corporation or other exempt recipient or (ii) provides a taxpayer identification number and certifies that no loss of exemption from backup withholding has occurred. Holders that are not US persons generally are not subject to information reporting or backup withholding. However, such a holder may be required to provide a certification of its non-US status in connection with payments received within the United States or through a US-related financial intermediary to establish that it is an exempt recipient. Backup withholding is not an additional tax. Amounts withheld as backup withholding may be credited against a holder’s US federal income tax liability. A holder may obtain a refund of any excess amounts withheld under the backup withholding rules by filing the appropriate claim for refund with the Internal Revenue Service and furnishing any required information.

Foreign asset reporting

In addition, a US holder that is an individual (and, to the extent provided in future regulations, an entity), may be subject to recently-enacted reporting obligations with respect to ordinary shares and ADSs if the aggregate value of these and certain other “specified foreign financial assets” exceeds $50,000. If required, this disclosure is made by filing Form 8938 with the US Internal Revenue Service. Significant penalties can apply if holders are required to make this disclosure and fail to do so. In addition, a US holder should consider the possible obligation to file online a FinCEN Form 114 - Foreign Bank and Financial Accounts Report as a result of holding ordinary shares or ADSs. Holders are encouraged to consult their US tax advisors with respect to these and other reporting requirements that may apply to their acquisition of ordinary shares and ADSs.

State and local taxes

In addition to US federal income tax, US holders of Securities may be subject to US state and local taxes with respect to such Securities. Holders of Securities are advised to consult their own tax advisers with regard to the application of US state and local income tax law to their particular situation.

ADSs-Ordinary Shares

French Taxes

Taxation of dividends

Under French law, dividends paid by a French corporation, such as Sanofi, to non-residents of France are generally subject to French withholding tax at a rate of 28% (12.8% for distributions made to individuals, and 15% for distributions made to not-for-profit organizations with a head office in a Member State of the European Economic Area which would be subject to the tax regime set forth under article 206 paragraph 2 of the French General Tax Code if its head office were located in France and which meet the criteria set forth in the Regulations BOI-RPPM-RCM-30-30-10-70-20191224, n ^o 130). Dividends paid by a French corporation, such as Sanofi, towards non-cooperative States or territories, as defined in Article 238-0 A of the French General Tax Code, will generally be subject to French withholding tax at a rate of 75%, irrespective of the tax residence of the beneficiary of the dividends if the dividends are received in such States or territories; however, eligible US holders entitled to Treaty benefits under the “Limitation on Benefits” provision contained in the Treaty who are US residents, as defined pursuant to the provisions of the Treaty and who receive dividends in non-cooperative States or territories, will not be subject to this 75% withholding tax rate.

Under the Treaty, the rate of French withholding tax on dividends paid to an eligible US holder who is a US resident as defined pursuant to the provisions of the Treaty and whose ownership of the ordinary shares or ADSs is not effectively connected with a permanent establishment or fixed base that such US holder has in France, is reduced to 15%, or to 5% if such US holder is a corporation and owns directly or indirectly at least 10% of the share capital of the issuing company; such US holder may claim a refund from the French tax authorities of the amount withheld in excess of the Treaty rates of 15% or 5%, if any. For US holders that are not individuals but are US residents, as defined pursuant to the provisions of the Treaty, the requirements for eligibility for Treaty benefits, including the reduced 5% or 15% withholding tax rates contained in the “Limitation on Benefits” provision of the Treaty, are complicated, and certain technical changes were made to these requirements by the protocol of January 13, 2009. US holders are advised to consult their own tax advisers regarding their eligibility for Treaty benefits in light of their own particular circumstances.

Dividends paid to an eligible US holder may immediately be subject to the reduced rates of 5% or 15% provided that such holder establishes before the date of payment that it is a US resident under the Treaty by completing and providing the depositary with a treaty form (Form 5000). Dividends paid to a US holder that has not filed the Form 5000 before the dividend payment date will be subject to French withholding tax at the rate of 28% and then reduced at a later date to 5% or 15%, provided that such holder duly completes and provides the French tax authorities with the treaty forms Form 5000 and Form 5001 before December 31 of the second calendar year following the year during which the dividend is paid. Pension funds and certain other tax-exempt entities are subject to the same general filing requirements as other US holders except that they may have to supply additional documentation evidencing their entitlement to these benefits.




160	SANOFI / FORM 20-F 2019

ITEM 10. ADDITIONAL INFORMATION

The depositary agrees to use reasonable efforts to follow the procedures established, or that may be established, by the French tax authorities (i) to enable eligible US holders to qualify for the reduced withholding tax rate provided by the Treaty, if available at the time the dividends are paid, or (ii) to recover any excess French withholding taxes initially withheld or deducted with respect to dividends and other distributions to which such US holders may be eligible from the French tax authorities and (iii) to recover any other available tax credits. In particular, associated forms (including Form 5000 and Form 5001, together with their instructions), will be made available by the depositary to all US holders registered with the depositary, and are also generally available from the US Internal Revenue Service.

The withholding tax refund, if any, ordinarily is paid within 12 months of filing the applicable French Treasury Form, but not before January 15 of the year following the calendar year in which the related dividend is paid.

Tax on sale or other disposition

In general, under the Treaty, a US holder who is a US resident for purposes of the Treaty will not be subject to French tax on any capital gain from the redemption (other than redemption proceeds characterized as dividends under French domestic law), sale or exchange of ordinary shares or ADSs unless the ordinary shares or the ADSs form part of the business property of a permanent establishment or fixed base that the US holder has in France. Special rules apply to holders who are residents of more than one country.

US Taxes

Taxation of dividends

For US federal income tax purposes, the gross amount of any distribution paid to US holders (that is, the net distribution received plus any tax withheld therefrom) will be treated as ordinary dividend income to the extent paid or deemed paid out of the current or accumulated earnings and profits of Sanofi (as determined under US federal income tax principles). Dividends paid by Sanofi will not be eligible for the dividends-received deduction generally allowed to corporate US holders.

Subject to certain exceptions for short-term and hedged positions, the US dollar amount of dividends received by an individual US holder with respect to the ADSs or our ordinary shares is currently subject to taxation at a maximum rate of 20% if the dividends are “qualified dividends”. Dividends paid on the ordinary shares or ADSs will be treated as qualified dividends if (i) the issuer is eligible for the benefits of a comprehensive income tax treaty with the United States that the Internal Revenue Service has approved for the purposes of the qualified dividend rules and (ii) the issuer was not, in the year prior to the year in which the dividend was paid, and is not, in the year in which the dividend is paid, a passive foreign investment company (“PFIC”). The Treaty has been approved for the purposes of the qualified dividend rules. Based on our financial statements and relevant market and shareholder data, we believe Sanofi was not a PFIC for US federal income tax purposes with respect to its 2019 taxable year. In addition, based on its current expectations regarding the value and nature of its assets, the sources and nature of its income, and relevant market and shareholder data, we do not anticipate that Sanofi will become a PFIC for its 2020 taxable year. Holders of ordinary shares and ADSs should consult their own tax advisers regarding the availability of the reduced dividend tax rate in light of their own particular circumstances.

If you are a US holder, dividend income received by you with respect to ADSs or ordinary shares generally will be treated as foreign source income for foreign tax credit purposes. The limitation on foreign taxes eligible for credit is calculated separately with respect to specific classes of income. Distributions out of earnings and profits with respect to the ADSs or ordinary shares generally will be treated as “passive category” income (or, in the case of certain US holders, “general category” income). Subject to certain limitations, French income tax withheld in connection with any distribution with respect to the ADSs or ordinary shares may be claimed as a credit against the US federal income tax liability of a US holder if such US holder elects for that year to credit all foreign income taxes. Alternatively, such French withholding tax may be taken as a deduction against taxable income. Foreign tax credits will not be allowed for withholding taxes imposed in respect of certain short-term or hedged positions in Securities and may not be allowed in respect of certain arrangements in which a US holder’s expected economic profit is insubstantial. The US federal income tax rules governing the availability and computation of foreign tax credits are complex. US holders should consult their own tax advisers concerning the implications of these rules in light of their particular circumstances.

To the extent that an amount received by a US holder exceeds the allocable share of our current and accumulated earnings and profits, such excess will be applied first to reduce such US holder’s tax basis in its ordinary shares or ADSs and then, to the extent it exceeds the US holder’s tax basis, it will constitute capital gain from a deemed sale or exchange of such ordinary shares or ADSs (see “- Tax on Sale or Other Disposition”, below).

The amount of any distribution paid in euros will be equal to the US dollar value of the euro amount distributed, calculated by reference to the exchange rate in effect on the date the dividend is received by a US holder of ordinary shares (or by the depositary, in the case of ADSs) regardless of whether the payment is in fact converted into US dollars on such date. US holders should consult their own tax advisers regarding the treatment of foreign currency gain or loss, if any, on any euros received by a US holder that are converted into US dollars on a date subsequent to receipt.

Distributions to holders of additional ordinary shares (or ADSs) with respect to their ordinary shares (or ADSs) that are made as part of a pro rata distribution to all ordinary shareholders generally will not be subject to US federal income tax. However, if a US holder has the option to receive a distribution in shares (or ADSs) or to receive cash in lieu of such shares (or ADSs), the distribution of shares (or ADSs) will be taxable as if the holder had received an amount equal to the fair market value of the distributed shares (or ADSs), and such holder’s tax basis in the distributed shares (or ADSs) will be equal to such amount.

Tax on sale or other disposition

In general, for US federal income tax purposes, a US holder that sells, exchanges or otherwise disposes of its ordinary shares or ADSs will recognize capital gain or loss in an amount equal to the US dollar value of the difference between the amount realized for the ordinary shares or ADSs and the US holder’s adjusted tax basis (determined in US dollars and under US federal income tax rules) in the ordinary shares or ADSs. Such gain or loss generally will be US-source gain or loss, and will be treated as long-term capital gain or loss if the US holder’s holding period in the ordinary shares or ADSs exceeds one year at the time of disposition. If the US holder is an individual, any capital gain generally will be subject to US federal income tax at preferential rates (currently a maximum of 20%) if specified minimum holding periods are met. The deductibility of capital losses is subject to significant limitations.

Medicare tax

Certain US holders who are individuals, estates or trusts are required to pay a Medicare tax of 3.8% (in addition to taxes they would otherwise be subject to) on their “net investment income” which would include, among other things, dividends and capital gains from the ordinary shares and ADSs.

ITEM 11. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

Item 11. Quantitative and Qualitative Disclosures about Market Risk ⁽¹⁾

General policy

Liquidity risk, foreign exchange risk and interest rate risk, as well as related counterparty risks, are managed centrally by our dedicated treasury team within the Group Finance Department. Where it is not possible to manage those risks centrally - in particular due to regulatory restrictions (such as foreign exchange controls) or local tax restrictions - credit facilities and/or currency lines, guaranteed whenever necessary by the parent company, are contracted by our subsidiaries locally with banks, under the supervision of the central treasury team.

Our financing and investment strategies, and our interest rate and currency hedging strategies, are reviewed monthly by the Group Finance Department.

Our policy prohibits the use of derivatives for speculative purposes.

Counterparty risk

Our financing and investing transactions, and our currency and interest rate hedges, are contracted with leading counterparties. We set limits for investment and derivative transactions with individual financial institutions, depending on the rating of each institution. Compliance with these limits, which are based on notional amounts weighted by the residual maturity and the nature of the commitment, is monitored on a daily basis.

The table below shows our total exposure as of December 31, 2019 by rating and in terms of our percentage exposure to the dominant counterparty.



(€ million)	Cash and cash equivalents (excluding mutual funds)	^(a)	Notional amounts of currency hedges	^(b)	Notional amounts of interest rate hedges	^(b)	General corporate purpose credit facilities
AA	6		1,166		250		500

Total	3,574		24,826		3,591		8,000
% / rating of dominant counterparty	18 % /A+		12% /AA-		22 % /AA-		6 % /BBB+


(a)	Cash equivalents include mutual fund investments of €5,332 million.


(b)	The notional amounts are translated into euros at the relevant closing exchange rate as of December 31, 2019 .


(c)	Includes interest rate swaps hedging fixed-rate bonds of €99 million held in a Professional Specialized Investment Fund dedicated to Sanofi, recognized in Long-term loans, advances and other non-current receivables (see note D.7. to our consolidated financial statements).

As of December 31, 2019 , we held investments in euro and US dollar denominated money-market mutual funds. Those instruments have low volatility, low sensitivity to interest rate risk, and a very low probability of loss of principal. The depositary banks of the mutual funds, and of Sanofi itself, have a long-term rating of at least A.

Realization of counterparty risk could impact our liquidity in certain circumstances.

Foreign exchange risk

A. Operating foreign exchange risk

A substantial portion of our net sales is generated in countries where the euro, which is our reporting currency, is not the functional currency. In 2019 , for example, 35.3 % of our net sales were generated in the United States, 22.7 % in Emerging Markets other than China (including countries that are, or may in future become, subject to exchange controls), 7.5 % in China and 5.3 % in Japan. Although we also incur expenses in those countries, the impact of those expenses is not enough wholly to offset the impact of exchange rates on our net sales. Consequently, our operating income may be materially affected by fluctuations in exchange rates between the euro and other currencies.

Sanofi operates a foreign exchange risk hedging policy to reduce the exposure of operating income to exchange rate movements. That policy involves regular assessments of Sanofi’s worldwide foreign currency exposure, based on foreign currency transactions carried out by the parent company and its subsidiaries. Those transactions mainly comprise sales, purchases, research costs, co-marketing and co-promotion expenses, and royalties. To reduce the exposure of those transactions to exchange rate movements, Sanofi contracts hedges using liquid derivative instruments, mainly forward currency purchases and sales, and also currency swaps.


(1)	The disclosures in this section supplement those provide in Note B.8.7. to the consolidated financial statements as regards the disclosure requirements of IFRS 7, and are covered by the independant registered public accounting firms' opinion on the consolidated financial statements.




SANOFI / FORM 20-F 2019	163

ITEM 11. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

The table below shows operating currency hedging instruments in place as of December 31, 2019 , with the notional amount translated into euros at the relevant closing exchange rate (see Note D.20. to the consolidated financial statements for the accounting classification of those instruments as of December 31, 2019 ).

Operating foreign exchange derivatives as of December 31, 2019 :



(€ million)	Notional amount	Fair value
Forward currency sales	3,372	(10)
of which US dollar	1,186	3
of which Chinese yuan renminbi	447	0
of which Singapore dollar	410	0
of which Russian rouble	184	(3)
of which Saudi riyal	133	1
Forward currency purchases	1,835	(5)
of which US dollar	602	(6)
of which Singapore dollar	525	1
of which Chinese yuan renminbi	130	0
of which Hungarian forint	60	0
of which Russian rouble	49	0
Total	5,207	(15)

The above positions mainly hedge future material foreign-currency cash flows arising after the end of the reporting period in relation to transactions carried out during the year ended December 31, 2019 and recognized in the balance sheet at that date. Gains and losses on hedging instruments (forward contracts) are calculated and recognized in parallel with the recognition of gains and losses on the hedged items. Due to this hedging relationship, the commercial foreign exchange profit or loss on these items (hedging instruments and hedged transactions) will be immaterial in 2020.

B. Financial foreign exchange risk

The cash pooling arrangements for foreign subsidiaries outside the euro zone, and some of Sanofi’s financing activities, expose certain Sanofi entities to financial foreign exchange risk (i.e. the risk of changes in the value of borrowings and loans denominated in a currency other than the functional currency of the borrower or lender). That foreign exchange exposure is hedged using derivative instruments (currency swaps or forward contracts) that alter the currency split of Sanofi’s net debt once those instruments are taken into account.

The table below shows financial currency hedging instruments in place as of December 31, 2019 , with the notional amounts translated into euros at the relevant closing exchange rate (see also Note D.20 to the consolidated financial statements for the accounting classification of these instruments as of December 31, 2019 ).

Financial foreign exchange derivatives as of December 31, 2019 :



(€ million)	Notional amount	Fair value		Expiry
Forward currency sales	8,515	40
of which US dollar	6,331 ⁽¹⁾	51		2020
of which Japanese yen	516	(5	)	2020
of which Pound sterling	297	1		2020
Forward currency purchases	10,975	78
of which US dollar	7,363	42		2020
of which Singapore dollar	2,332	32
of which Chinese yuan renminbi	270	2		2020
Total	19,490	118


(1)	Includes forward sales with a notional amount of $3,615 million expiring in 2020 , designated as a hedge of Sanofi’s net investment in Bioverativ. As of December 31, 2019 , the fair value of these forward contracts represented an asset of €29 million ; the opposite entry was recognized in Other comprehensive income , with the impact on financial income and expense being immaterial.

These forward currency contracts generate a net financial foreign exchange gain or loss arising from the interest rate differential between the hedged currency and the euro, given that the foreign exchange gain or loss on the foreign-currency borrowing and loans is offset by the change in the intrinsic value of the hedging instruments. The interest rate differential is recognized within cost of net debt (see note D.29. to our consolidated financial statements).

We may also hedge some future foreign-currency investment or divestment cash flows.




164	SANOFI / FORM 20-F 2019

ITEM 11. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

C. Other foreign exchange risks

A significant proportion of our net assets is denominated in US dollars (see Note D.35. to the consolidated financial statements). As a result, any fluctuation in the exchange rate of the US dollar against the euro automatically impacts the amount of our equity as expressed in euros.

In addition, we use the euro as our reporting currency. Consequently, if one or more European Union Member States were to abandon the euro as a currency, the resulting economic upheavals - in particular, fluctuations in exchange rates - could have a significant impact on the terms under which we can obtain financing and on our financial results, the extent and consequences of which are not currently foreseeable.

Liquidity risk

We operate a centralized treasury platform whereby all surplus cash and financing needs of our subsidiaries are invested with or funded by the parent company (where permitted by local legislation). The central treasury department manages our current and projected financing, and ensures that Sanofi is able to meet its financial commitments by maintaining sufficient cash and confirmed credit facilities for the size of our operations and the maturity of our debt (see Notes D.17.1.c and D.17.1.g to the consolidated financial statements).

We diversify our short-term investments with leading counterparties using money-market products with instant access or with a maturity of less than three months. As of December 31, 2019 , cash and cash equivalents amounted to € 9 427 million, and our short-term investments predominantly comprised:


▪	colle ctive investments in euro and US dollar denominated money-market mutual funds. All such funds can be traded on a daily basis and the amount invested in each fund may not exceed 10% of the aggregate amount invested in such funds;


▪	amounts invested directly with banks and non-financial institutions in the form of instant access deposits, term deposits, and Negotiable European Commercial Paper with a maturity of no more than three months.

As of December 31, 2019 , the Group also had €8 billion of undrawn general corporate purpose confirmed credit facilities, half expiring December 2020 and half December 2021. Those credit facilities are not subject to financial covenant ratios.

Our policy is to diversify our sources of funding through public or private issuances of debt securities, in the United States (shelf registration statement) and Europe (Euro Medium Term Note program). In addition, our A-1+/P-1 short-term rating gives us access to commercial paper programs in the United States and in France. The average maturity of our total debt was 5.4 years as of December 31, 2019 , compared with 5.8 years as of December 31, 2018 . During 2019 , we did not draw down on our French commercial paper program. Average drawdowns under the US commercial paper program during 2019 were €2.9 billion (maximum €3.6 billion); the average maturity of those drawdowns was three months. As of December 31, 2019 , neither of those programs was being utilized.

In the event of a liquidity crisis, we could be exposed to difficulties in calling up our available cash, a scarcity of sources of funding including the above-mentioned programs, and/or a deterioration in their terms. This situation could damage our capacity to refinance our debt or to issue new debt on reasonable terms.

Interest rate risk

Sanofi issues debt in two currencies, the euro and the US dollar, and also invests its cash and cash equivalents in those currencies. Sanofi also operates cash pooling arrangements to manage the surplus cash and short-term liquidity needs of foreign subsidiaries located outside the euro zone.

To optimize the cost of debt or reduce the volatility of debt and manage its exposure to financial foreign exchange risk, Sanofi uses derivative instruments (interest rate swaps, cross currency swaps, currency swaps and forward contracts) that alter the fixed/floating rate split and the currency split of its net debt.

The projected full-year sensitivity to interest rate fluctuations of our debt, net of cash and cash equivalents for 2020 is as follows:



Change in short-term interest rates	Impact on pre-tax net income (€ million)		Impact on pre-tax income/(expense) recognized directly in equity (€ million)
+100 bp	65		—
+25 bp	16		—
-25 bp	(16	)	—
-100 bp	(65	)	—

Stock market risk

It is our policy not to trade on the stock market for speculative purposes.

During 2019, Sanofi contracted derivative instruments (collars) on 593,712 shares of Dexcom Inc. (see No te D.7.1., Equity instruments at fair value through other comprehensive income). Those collars were designated as fair value hedges of the Dexcom shares, and had a negative fair value as of December 31, 2019 of €4 million , recognized in full in Other comprehensive income .

12.D American depositary shares

General

JPMorgan Chase Bank, N.A. (“JPMorgan”), as depositary, issues Sanofi ADSs in certificated form (evidenced by an ADR) or book-entry form. Each ADR is a certificate evidencing a specific number of Sanofi ADSs. Each Sanofi ADS represents one-half of one Sanofi ordinary share (or the right to receive one-half of one Sanofi ordinary share) deposited with the Paris, France office of BNP Paribas, as custodian. Each Sanofi ADS also represents an interest in any other securities, cash or other property that may be held by the depositary under the deposit agreement. The depositary’s office is located at 4 New York Plaza, 12th Floor, New York, New York 10004.

A holder may hold Sanofi ADSs either directly or indirectly through his or her broker or other financial institution. The following description assumes holders hold their Sanofi ADSs directly, in certificated form evidenced by ADRs. Holders who hold the Sanofi ADSs indirectly must rely on the procedures of their broker or other financial institution to assert the rights of ADR holders described in this section. Holders should consult with their broker or financial institution to find out what those procedures are.

Holders of Sanofi ADSs do not have the same rights as holders of Sanofi shares. French law governs shareholder rights. The rights of holders of Sanofi ADSs are set forth in the deposit agreement between Sanofi and JPMorgan and in the ADR. New York law governs the deposit agreement and the ADRs.

The following is a summary of certain terms of the deposit agreement, as amended. Our form of second amended and restated deposit agreement was filed as an exhibit to our Post-Effective Amendment No. 1 to Form F-6 filed on February 13, 2015. To the extent any portion of the amendment and restatement would prejudice any substantial existing right of holders of ADSs under the first amended and restated deposit agreement, such portion shall not become effective as to such holders until 30 days after holders have received notice thereof. For more complete information, holders should read the entire second amended and restated deposit agreement and the ADR itself. Holders may also inspect a copy of the current deposit agreement at the depositary’s office.

Share dividends and other distributions

Receipt of dividends and other distributions

The depositary has agreed to pay to holders of Sanofi ADSs the cash dividends or other distributions that it or the custodian receives on the deposited Sanofi ordinary shares and other deposited securities after deducting its fees and expenses. Holders of Sanofi ADSs will receive these distributions in proportion to the number of Sanofi ADSs that they hold.

Cash. The depositary will convert any cash dividend or other cash distribution paid on the shares into U.S. dollars if, in its judgment, it can do so on a reasonable basis and can transfer the U.S. dollars to the United States. If the depositary determines that such a conversion and transfer is not possible, or if any approval from the French government is needed and cannot be obtained within a reasonable period, then the depositary may (1) distribute the foreign currency received by it to the holders of Sanofi ADSs or (2) hold the foreign currency distribution (uninvested and without liability for any interest) for the account of holders of Sanofi ADSs.

In addition, if any conversion of foreign currency, in whole or in part, cannot be effected to some holders of Sanofi ADSs, the deposit agreement allows the depositary to distribute the dividends only to those ADR holders to whom it is possible to do so. It will hold the foreign currency it cannot convert into U.S. dollars for the account of the ADR holders who have not been paid. It will not invest the funds it holds and it will not be liable for any interest.

Before making a distribution, any withholding taxes that must be paid under French law will be deducted. The depositary will distribute only whole U.S. dollars and cents and will round fractional cents down to the nearest whole cent. Exchange rate fluctuations during a period when the depositary cannot convert euros into U.S. dollars may result in holders losing some or all of the value of a distribution.

Shares. The depositary may, and at our request will, distribute new ADRs representing any shares we distribute as a dividend or free distribution, if we furnish it promptly with satisfactory evidence that it is legal to do so. At its option, the depositary may distribute fractional Sanofi ADSs. If the depositary does not distribute additional Sanofi ADSs, the outstanding ADRs will also represent the new shares. The depositary may withhold any tax or other governmental charges, or require the payment of any required fees and expenses, prior to making any distribution of additional Sanofi ADSs.

Rights to Receive Additional Shares. If we offer holders of Sanofi ordinary shares any rights to subscribe for additional shares or any other rights, the depositary, after consultation with us, will, in its discretion, either (1) make these rights available to holders or (2) dispose of such rights on behalf of holders and make the net proceeds available to holders. The depositary may make rights available to certain holders but not others if it determines it is lawful and feasible to do so. However, if, under the terms of the offering or for any other reason, the depositary may not make such rights available or dispose of such rights and make the net proceeds available, it will allow the rights to lapse. In that case, holders of Sanofi ADSs will receive no value for them.




166	SANOFI / FORM 20-F 2019

ITEM 12D. AMERICAN DEPOSITARY SHARES

In circumstances where rights would not otherwise be distributed by the depositary to holders of Sanofi ADSs, a holder of Sanofi ADSs may nonetheless request, and will receive from the depositary, any instruments or other documents necessary to exercise the rights allocable to that holder if the depositary first receives written notice from Sanofi that (1) Sanofi has elected, in its sole discretion, to permit the rights to be exercised and (2) such holder has executed the documents Sanofi has determined, in its sole discretion, are reasonably required under applicable law.

If the depositary makes rights available to holders of Sanofi ADSs, upon instruction from such holders, it will exercise the rights and purchase the shares on such holder’s behalf. The depositary will then deposit the shares and deliver ADRs to such holders. It will only exercise rights if holders of Sanofi ADSs pay it the exercise price and any other charges the rights require such holders to pay.

U.S. securities laws may restrict the sale, deposit, cancellation or transfer of ADRs issued upon exercise of rights. For example, holders of Sanofi ADSs may not be able to trade Sanofi ADSs freely in the United States. In this case, the depositary may deliver Sanofi ADSs under a separate restricted deposit agreement that will contain the same provisions as the deposit agreement, except for changes needed to implement the required restrictions.

Other Distributions. The depositary will distribute to holders of Sanofi ADSs anything else we may distribute on deposited securities (after deduction or upon payment of fees and expenses or any taxes or other governmental charges) by any means it thinks is legal, equitable and practical. If, for any reason, it cannot make the distribution in that way, the depositary may sell what we distributed and distribute the net proceeds of the sale in the same way it distributes cash dividends, or it may choose any other method to distribute the property it deems equitable and practicable.

The depositary is not responsible if it decides that it is unlawful or impractical to make a distribution available to any holders of Sanofi ADSs. We have no obligation to register Sanofi ADSs, shares, rights or other securities under the U.S. Securities Act of 1933, as amended. We also have no obligation to take any other action to permit the distribution of ADRs, shares, rights or anything else to holders of Sanofi ADSs. This means that holders may not receive the distribution we make on our shares or any value for them if it is illegal or impractical for the depositary to make them available to such holders.

Elective Distributions. Whenever we intend to distribute a dividend payable at the election of shareholders either in cash or in additional shares, we will give prior notice thereof to the depositary and will indicate whether we wish the elective distribution to be made available to holders of Sanofi ADSs. In that case, we will assist the depositary in determining whether that distribution is lawful and reasonably practicable. The depositary will make the election available to holders of Sanofi ADSs only if it is reasonably practicable and if we have provided all the documentation contemplated in the deposit agreement. In that case, the depositary will establish procedures to enable holders of Sanofi ADSs to elect to receive either cash or additional ADSs, in each case as described in the deposit agreement. If the election is not made available to holders of Sanofi ADSs, such holders will receive either cash or additional Sanofi ADSs, depending on what a shareholder in France would receive for failing to make an election, as more fully described in the deposit agreement.

Deposit, withdrawal and cancellation

Delivery of ADRs

The depositary will deliver ADRs if the holder or his or her broker deposit shares or evidence of rights to receive shares with the custodian. Upon payment of its fees and expenses and any taxes or charges, such as stamp taxes or stock transfer taxes or fees, the depositary will register the appropriate number of Sanofi ADSs in the names the holder requests and will deliver the ADRs to the persons the holder requests at its office.

Obtaining Sanofi ordinary shares

A holder may turn in his or her ADRs at the depositary’s office. Upon payment of its fees and expenses and any taxes or charges, such as stamp taxes or stock transfer taxes or fees, the depositary will deliver (1) the underlying shares to an account designated by the holder and (2) any other deposited securities underlying the ADR at the office of a custodian or, at the holder’s request, risk and expense, the depositary will deliver the deposited securities at its office.

Voting rights

A holder may instruct the depositary to vote the Sanofi ordinary shares underlying his or her Sanofi ADSs at any meeting of Sanofi shareholders, but only if we request that the depositary ask for holder instructions. Otherwise, holders will not be able to exercise their right to vote unless they withdraw the underlying ordinary shares from the ADR program and vote as an ordinary shareholder. However, holders may not know about the meeting sufficiently in advance to timely withdraw the underlying ordinary shares.

If we ask for holder instructions in connection with a meeting of Sanofi shareholders, the depositary will provide materials to holders of Sanofi ADSs in the manner described under the heading “Notices and Reports; Rights of Holders to Inspect Books” below. For any instructions to be valid, the depositary must receive them on or before the date specified in the materials distributed by the depositary. The depositary will endeavor, in so far as practical, subject to French law and the provisions of our statuts , to vote or to have its agents vote the shares or other deposited securities as holders may validly instruct. The depositary will only vote or attempt to vote shares as holders validly instruct.

We cannot guarantee holders that they will receive the voting materials with sufficient time to enable them to return any voting instructions to the depositary in a timely manner to vote their shares. As long as they act in good faith, neither the depositary nor its agents will be responsible for failing to carry out voting instructions or for the manner of carrying out voting instructions. This means that holders may not be able to exercise their right to vote and there may be nothing holders can do if their shares are not voted as they requested.

Similar to our shares, Sanofi ADSs evidenced by ADRs that are registered in the name of the same owner for at least two (2) years are eligible for double voting rights so long as certain procedures are followed, as set out in the deposit agreement. For additional information regarding double voting rights, see “Item 10. Additional Information - B. Memorandum and Articles of Association - Voting Rights”.




SANOFI / FORM 20-F 2019	167

ITEM 12D. AMERICAN DEPOSITARY SHARES

The deposit agreement allows the depositary and Sanofi to change the voting procedures or require additional voting procedures in addition to the ones described above if necessary or appropriate. For example, holders might be required to arrange to have their Sanofi ADSs deposited in a blocked account for a specified period of time prior to a shareholders’ meeting in order to be allowed to give voting instructions.

Notices and reports; rights of holders to inspect books

On or before the first date on which we give notice, by publication or otherwise, of any meeting of holders of shares or other deposited securities, or of any adjourned meeting of such holders, or of the taking of any action in respect of any cash or other distributions or the offering of any rights, we will transmit to the depositary a copy of the notice.

Upon notice of any meeting of holders of shares or other deposited securities, if requested in writing by Sanofi, the depositary will, as soon as practicable, mail to the holders of Sanofi ADSs a notice, the form of which is in the discretion of the depositary, containing (1) a summary in English of the information contained in the notice of meeting provided by Sanofi to the depositary, (2) a statement that the holders as of the close of business on a specified record date will be entitled, subject to any applicable provision of French law and of our statuts , to instruct the depositary as to the exercise of the voting rights, if any, pertaining to the amount of shares or other deposited securities represented by their respective ADSs and (3) a statement as to the manner in which such instructions may be given. Notwithstanding the above, the depositary may, to the extent not prohibited by law or regulations, or by the requirements of the NYSE, in lieu of distribution of the materials provided to the depositary as described above, distribute to the holders a notice that provides holders with, or otherwise publicizes to holders, instructions on how to retrieve such materials or receive such materials upon request (i.e. by reference to a website containing the materials for retrieval or a contact for requesting copies of the materials).

The depositary will make available for inspection by ADS holders at the depositary’s office any reports and communications, including any proxy soliciting material, received from us that are both (1) received by the depositary as the holder of the deposited securities and (2) made generally available to the holders of such deposited securities by us. The depositary will also, upon written request, send to ADS holders copies of such reports when furnished by us pursuant to the deposit agreement. Any such reports and communications, including any such proxy soliciting material, furnished to the depositary by us will be furnished in English to the extent such materials are required to be translated into English pursuant to any regulations of the SEC.

The depositary will keep books for the registration of ADRs and transfers of ADRs that at all reasonable times will be open for inspection by the holders provided that such inspection is not for the purpose of communicating with holders in the interest of a business or object other than our business or a matter related to the deposit agreement or the ADRs.

Fees and expenses

Fees payable by ADS holders

Pursuant to the deposit agreement, holders of our ADSs may have to pay to JPMorgan, either directly or indirectly, fees or charges up to the amounts set forth in the table below.



Associated Fee	Depositary Action
$5.00 or less per 100 ADSs (or portion thereof)	Execution and delivery of ADRs for distributions and dividends in shares and rights to subscribe for additional shares or rights of any other nature and surrender of ADRs for the purposes of withdrawal, including the termination of the deposit agreement.

In addition to the fees outlined above, each holder will be responsible for any taxes or other governmental charges payable on his or her Sanofi ADSs or on the deposited securities underlying his or her Sanofi ADSs. The depositary may refuse to transfer a holder’s Sanofi ADSs or allow a holder to withdraw the deposited securities underlying his or her Sanofi ADSs until such taxes or other charges are paid. It may apply payments owed to a holder or sell deposited securities underlying a holder’s Sanofi ADSs to pay any taxes owed, and the holder will remain liable for any deficiency. If it sells deposited securities, it will, if appropriate, reduce the number of Sanofi ADSs to reflect the sale and pay to the holder any proceeds, or send to the holder any property, remaining after it has paid the taxes. For additional information regarding taxation, see “Item 10. Additional Information - E. Taxation”.




168	SANOFI / FORM 20-F 2019

ITEM 12D. AMERICAN DEPOSITARY SHARES

Fees paid to Sanofi by the depositary

JPMorgan, as depositary, has agreed to reimburse Sanofi for certain expenses (subject to certain limits) Sanofi incurs relating to legal fees, investor relations servicing, investor-related presentations, ADR-related advertising and public relations in those jurisdictions in which the ADRs may be listed or otherwise quoted, investor relations channel, perception studies, accountants’ fees in relation to our annual report on Form 20-F or any other expenses directly or indirectly relating to managing the program or servicing the ADR holders. The depositary has also agreed to provide additional amounts to us based on certain performance indicators relating to the ADR facility and fees collected by it. From January 1, 2019 to December 31, 2019 , we received a total amount of $11,127,476 from JPMorgan. In addition to these payments, JPMorgan has agreed to waive servicing fees we may incur in connection with routine corporate actions such as annual general meetings and dividend distributions, as well as for other assistance JPMorgan may provide to us, such as preparation of tax and regulatory compliance documents for holders and investor relations advisory services.

Changes affecting deposited securities

If we:


▪	change the nominal or par value of our Sanofi ordinary shares;


▪	recapitalize, reorganize, merge or consolidate, liquidate, sell assets, or take any similar action;


▪	reclassify, split up or consolidate any of the deposited securities; or


▪	distribute securities on the deposited securities that are not distributed to holders;

then either:


▪	the ca sh, shares or other securities received by the depositary will become deposited securities and each Sanofi ADS will automatically represent its equal share of the new deposited securities; or


▪	the depositary may, a nd will if we ask it to, distribute some or all of the cash, shares or other securities it receives. It may also deliver new ADRs or ask holders to surrender their outstanding ADRs in exchange for new ADRs identifying the new deposited securities.

Disclosure of interests

The obligation of a holder or other person with an interest in our shares to disclose information under French law and under our statuts also applies to holders and any other persons, other than the depositary, who have an interest in the Sanofi ADSs. The consequences for failing to comply with these provisions are the same for holders and any other persons with an interest as a holder of our ordinary shares. For additional information regarding these obligations, see “Item 10. Additional Information - B. Memorandum and Articles of Association - Requirements for Holdings Exceeding Certain Percentages”.

Amendment and termination

We may agree with the depositary to amend the deposit agreement and the ADRs without the consent of the ADS holders for any reason. If the amendment adds or increases fees or charges, except for taxes and other governmental charges or registration fees, cable, telex or facsimile transmission costs, delivery costs or other such expenses, or prejudices a substantial right of holders of Sanofi ADSs, it will only become effective 30 days after the depositary notifies such holders of the amendment. However, we may not be able to provide holders of Sanofi ADSs with prior notice of the effectiveness of any modifications or supplements that are required to accommodate compliance with applicable provisions of law, whether or not those modifications or supplements could be considered to be materially prejudicial to the substantial rights of holders of Sanofi ADSs. At the time an amendment becomes effective, such holders will be considered, by continuing to hold their ADR, to have agreed to the amendment and to be bound by the ADR and the deposit agreement as amended.

The depositary will terminate the agreement if we ask it to do so. The depositary may also terminate the agreement if the depositary has told us that it would like to resign and we have not appointed a new depositary bank within 90 days. In both cases, the depositary must notify holders of Sanofi ADSs at least 30 days before termination.

After termination, the depositary and its agents will be required to do only the following under the deposit agreement: (1) collect distributions on the deposited securities, (2) sell rights and other property as provided in the deposit agreement and (3) deliver shares and other deposited securities upon cancellation of ADRs. Six months or more after termination, the depositary may sell any remaining deposited securities by public or private sale. After that, the depositary will hold the money it receives on the sale, as well as any other cash it is holding under the deposit agreement, for the pro rata benefit of the holders of Sanofi ADSs that have not surrendered their Sanofi ADSs. It will have no liability for interest. Upon termination of the deposit agreement, the depositary’s only obligations will be to account for the proceeds of the sale and other cash and with respect to indemnification. After termination, our only obligation will be with respect to indemnification and to pay certain amounts to the depositary.

Limitations on obligations and liability to holders of Sanofi ADSs

The deposit agreement expressly limits our obligations and the obligations of the depositary, and it limits our liability and the liability of the depositary. In particular, please note the following:


▪	we and the depositary are obligated only to take the actions specifically set forth in the deposit agreement without gross negligence or bad faith;


▪	we and the depositary are not liable if either is prevented or delayed by law or circumstances beyond its control from performing its obligations under the deposit agreement;


▪	we and the depositary are not liable if either exercises, or fails to exercise, any discretion permitted under the deposit agreement;




SANOFI / FORM 20-F 2019	169

ITEM 12D. AMERICAN DEPOSITARY SHARES


▪	we and the depositary have no obligation to become involved in a lawsuit or other proceeding related to the Sanofi ADSs or the deposit agreement on holders’ behalf or on behalf of any other party, unless indemnity satisfactory to it against all expense and liability is furnished as often as may be required;


▪	we and the depositary are not liable for the acts or omissions made by, or the insolvency of, any securities depository, clearing agency or settlement system or the custodian, subject to certain exceptions and to the extent the custodian is not a branch or affiliate of JPMorgan;


▪	the depositary is not liable for the price received in connection with any sale of securities, the timing thereof or any delays, acts, omissions to act, errors, defaults or negligence on the part of the party so retained in connection with any such sale or proposed sale;


▪	we and the depositary may rely without any liability upon any written notice, request, direction, instruction or other document believed by either of us to be genuine and to have been signed or presented by the proper parties; and


▪	we and the depositary are not liable for any action or nonaction taken in reliance upon the advice of or information from legal counsel, accountants, any person presenting ordinary shares for deposit, any ADS holder, or any other person believed in good faith to be competent to give such advice or information.

In addition, the depositary will not be liable for any acts or omissions made by a successor depositary. Moreover, neither we nor the depositary nor any of our respective agents will be liable to any holder of Sanofi ADSs for any indirect, special, punitive or consequential damages.

Pursuant to the terms of the deposit agreement, we and the depositary have agreed to indemnify each other under certain circumstances.

Requirements for depositary actions

Before the depositary will deliver or register the transfer of Sanofi ADSs, make a distribution on Sanofi ADSs or process a withdrawal of shares, the depositary may require:


▪	payment of stock transfer or other taxes or other governmental charges and transfer or registration fees charged by third parties for the transfer of any shares or other deposited securities;


▪	production of satisfactory proof of the identity and genuineness of any signature or other information it deems necessary; and


▪	compliance with regulations it may establish, from time to time, consistent with the deposit agreement, including presentation of transfer documents.

The depositary may refuse to deliver Sanofi ADSs, register transfers of Sanofi ADSs or permit withdrawals of shares when the transfer books of the depositary or our transfer books are closed, or at any time if the depositary or we think it advisable to do so.

Right to receive the shares underlying the Sanofi ADSs

Holders have the right to cancel their Sanofi ADSs and withdraw the underlying Sanofi ordinary shares at any time except:


▪	when temporary delays arise when we or the depositary have closed our transfer books or the deposit of shares in connection with voting at a shareholders’ meeting, or the payment of dividends;


▪	when the holder or other holders of Sanofi ADSs seeking to withdraw shares owe money to pay fees, taxes and similar charges; or


▪	when it is necess ary to prohibit withdrawals in order to comply with any laws or governmental regulations that apply to Sanofi ADSs or to the withdrawal of shares or other deposited securities.

This right of withdrawal may not be limited by any other provision of the deposit agreement.

Pre-release of Sanofi ADSs

Unless we instruct the depositary not to, the deposit agreement permits the depositary to deliver Sanofi ADSs before deposit of the underlying shares. This is called a pre-release of the Sanofi ADSs. The depositary may also deliver shares upon cancellation of pre-released Sanofi ADSs (even if the Sanofi ADSs are cancelled before the pre-release transaction has been closed out). A pre-release is closed out as soon as the underlying shares are delivered to the depositary. The depositary may receive Sanofi ADSs instead of shares to close out a pre-release. Unless otherwise agreed in writing, the depositary may pre-release Sanofi ADSs only under the following conditions: (1) before or at the time of the pre-release, the person to whom the pre-release is being made must represent to the depositary in writing that it or its customer (i) owns the shares or Sanofi ADSs to be deposited, (ii) assigns all beneficial rights, title and interest in such shares or ADRs to the depositary in its capacity as depositary and (iii) will not take any action with respect to such shares or ADRs that is inconsistent with the transfer of beneficial ownership, other than in satisfaction of such pre-release; (2) the pre-release must be fully collateralized with cash, U.S. government securities or other collateral that the depositary considers appropriate; (3) the depositary must be able to close out the pre-release on not more than five business days’ notice; and (4) the depositary may require such further indemnities and credit regulations as it deems appropriate. In addition, the depositary will limit the number of Sanofi ADSs that may be outstanding at any time as a result of pre-release, although the depositary may disregard the limit from time to time, if it thinks it is appropriate to do so. The depositary may retain for its own account any compensation received by it in connection with the foregoing. Any holder of pre-release ADRs should consult its tax and other advisors about the implications of pre-release for its particular situation.

While the provisions of the deposit agreement permitting the pre-release of the Sanofi ADSs as described above remain in place, the depositary has informed Sanofi hat it has decided to no longer deliver Sanofi ADSs before deposit of the underlying shares.

(a)

Our Chief Executive Officer and principal financial officer, after evaluating the effectiveness of our disclosure controls and procedures (as defined in Exchange Act Rule 13a-15(e)) as of the end of the period covered by this Form 20-F, have concluded that, as of such date, our disclosure controls and procedures were effective to ensure that material information relating to Sanofi was timely made known to them by others within Sanofi.


(b)	Report of Management on Internal Control Over Financial Reporting.

Management of the Company is responsible for establishing and maintaining adequate internal control over financial reporting, as such term is defined in Exchange Act Rule 13a-15(f). Management assessed the effectiveness of internal control over financial reporting as of December 31, 2019 based on the framework in “Internal Control - Integrated Framework” (2013 framework) issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO).

Based on that assessment, management has concluded that the Company’s internal control over financial reporting was effective as of December 31, 2019 to provide reasonable assurance regarding the reliability of its financial reporting and the preparation of its financial statements for external purposes, in accordance with generally accepted accounting principles.

Due to its inherent limitations, internal control over financial reporting may not prevent or detect misstatements, and can only provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.

The effectiveness of the Company’s internal control over financial reporting has been audited by PricewaterhouseCoopers Audit and Ernst & Young et Autres, independent registered public accounting firms, as stated in their report on the Company’s internal control over financial reporting as of December 31, 2019 , which is included herein. See paragraph (c) of the present Item 15, below.


(c)	See report of PricewaterhouseCoopers Audit and Ernst & Young et Autres, independent registered public accounting firms, included under “Item 18. Financial Statements” on page F-3.


(d)	There were no changes to our internal control over financial reporting that occurred during the period covered by this Form 20 - F that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

Item 16A. Audit Committee Financial Expert

Our Board of Directors has determined that Fabienne Lecorvaisier, Emmanuel Babeau and Diane Souza, the three directors serving on the Audit Committee, are independent financial experts within the meaning of paragraph 407 of the Sarbanes-Oxley Act of 2002.

The Board of Directors deemed Fabienne Lecorvaisier to be a financial expert based on her education and her experience in corporate finance in various international banks and as Chief Financial Officer of Essilor and Air Liquide. She is now Executive Vice President, in charge of Finance, Operations Control and General Secretariat of Air Liquide Group.

The Board of Directors deemed Emmanuel Babeau to be a financial expert based on his education and his experience in audit and in corporate finance in major corporations, as Chief Financial Officer of Pernod Ricard and Schneider Electric SE, and as chairman of the audit committee of Sodexo. He is now Deputy Chief Executive Officer in charge of Finance and Legal Affairs of Schneider Electric SE.

The Board of Directors deemed Diane Souza to be a financial expert based on her education (she is a certified public accountant) and her experience in audit and tax in major international corporations, as Chief Financial Officer of Aetna’s Guaranteed Products business, and as Chief Executive Officer of the UnitedHealthcare Specialty Benefits.

The Board of Directors has determined that all three directors meet the independence criteria of US Securities and Exchange Commission Rule 10A-3 and meet the French AFEP-MEDEF Code criteria of independence applied by the Board of Directors for general corporate governance purposes (see Item 16G, below).

Item 16B. Code of Ethics

We have adopted a financial code of ethics, as defined in Item 16B. of Form 20-F under the Exchange Act.

ITEM 16G. CORPORATE GOVERNANCE

Item 16G. Corporate Governance

Sanofi is incorporated under the laws of France, with securities listed on regulated public markets in the United States (NASDAQ Global Select Market) and France (Euronext Paris). Consequently, as described further in our annual report, our corporate governance framework reflects the mandatory provisions of French corporate law, the securities laws and regulations of France and the United States and the rules of the aforementioned public markets.

As a “foreign private issuer,” as defined in rules promulgated under the U.S. Securities Exchange Act of 1934, as amended, (the “Exchange Act”), Sanofi is permitted, pursuant to NASDAQ Stock Market Rule 5615(a)(3), to follow its home country practice in lieu of certain NASDAQ corporate governance requirements applicable to U.S. corporations listed on the NASDAQ Stock Market. Sanofi has informed NASDAQ that it intends to follow corporate governance standards under French law to the extent permitted by the NASDAQ Stock Market rules and U.S. securities laws, as further discussed below.

We generally follow the “AFEP-MEDEF” corporate governance recommendations for French listed issuers (hereafter referred to as the “AFEP-MEDEF Code”). As a result, our corporate governance framework is similar in many respects to, and provides investor protections that are comparable to - or in some cases, more stringent than - the corresponding rules of the NASDAQ Global Select Market. Nevertheless, there are important differences to keep in mind.

In line with NASDAQ Stock Market rules applicable to domestic issuers, a majority of Sanofi’s Board of Directors is comprised of independent directors. Sanofi evaluates the independence of members of our Board of Directors using the standards of the French AFEP-MEDEF Code as the principal reference. We believe that AFEP-MEDEF’s overarching criteria for independence - no relationship of any kind whatsoever with the Company, its group or the management of either that is such as to color a Board member’s judgment - are on the whole consistent with the goals of the NASDAQ Global Select Market’s rules although the specific tests proposed under the two standards may vary on some points. We have complied with the Audit Committee independence and other requirements of the Rule 10A-3 under the Exchange Act, adopted pursuant to the Sarbanes-Oxley Act of 2002. Each member of our Audit Committee and Compensation Committee meets the independence standards of the AFEP-MEDEF Code and the independence requirements of NASDAQ’s listing rules and Rule 10A-3 promulgated under the Sarbanes-Oxley Act of 2002, as amended.

Sanofi follows the recommendation of the AFEP-MEDEF Code that at least one meeting not attended by the company’s executive officers be organized each year. Accordingly, Sanofi’s Board Charter provides that the Board of Directors shall organize at least two meetings a year without its executive officers, thereby providing the Chairman with the option to include or not non-independent directors and directors representing employees, as the case may require, depending on the agenda of the meeting. Sanofi’s practice in that respect departs from NASDAQ’s Listing Rule 5605(b)(2), which provides that independent directors must have regularly scheduled meetings at which only independent directors are present.

Under French law, the committees of our Board of Directors are advisory only, and where the NASDAQ Listing Rule 5600 Series would vest certain decision-making powers with specific committees by delegation (e.g. the appointment of Sanofi’s auditors by the Audit Committee), under French law, our Board of Directors remains the only competent body to take such decisions, albeit taking into account the recommendation of the relevant committees. Additionally, under French corporate law, it is the Shareholders of Sanofi voting at the Shareholders’ General Meeting that have the authority to appoint our auditors upon consideration of the proposal of our Board of Directors, although our Board Charter provides that the Board of Directors will make its proposal on the basis of the recommendation of our Audit Committee. We believe that this requirement of French law, together with the additional legal requirement that two sets of statutory auditors be appointed, share the NASDAQ Global Select Market’s underlying goal of ensuring that the audit of our accounts be conducted by auditors independent from company management.

In addition to the oversight role of our Compensation Committee for questions of management compensation including by way of equity, under French law any option or restricted share plans or other share capital increases, whether for the benefit of senior management or employees, may only be adopted by the Board of Directors pursuant to and within the limits of a shareholder resolution approving the related capital increase and delegating to the Board the authority to implement such operations.

As described above, a number of issues, which could be resolved directly by a board or its committees in the United States, require the additional protection of direct shareholder consultation in France.

Because we are a ‘foreign private issuer’ as described above, our Chief Executive Officer and our Chief Financial Officer issue the certifications required by §302 and §906 of the Sarbanes Oxley Act of 2002 on an annual basis (with the filing of our annual report on Form 20-F) rather than on a quarterly basis as would be the case of a U.S. corporation filing quarterly reports on Form 10-Q.

French corporate law provides that the Board of Directors must vote to approve a broadly defined range of transactions that could potentially create conflicts of interest between Sanofi on the one hand and its Directors and Chief Executive Officer on the other hand, which are then presented to shareholders for approval at the next annual meeting. This legal safeguard operates in place of certain provisions of the NASDAQ Stock Market Listing Rules.

Sanofi is governed by the French Commercial Code, which provides that an ordinary general meeting of the shareholders may validly deliberate when first convened if the shareholders present or represented hold at least one fifth of the voting shares. If it is reconvened, no quorum is required. The French Commercial Code further provides that the shareholders at an extraordinary general meeting may validly deliberate when first convened only if the shareholders present or represented hold at least one quarter of the voting shares and, if reconvened, one fifth of the voting shares. Therefore, Sanofi will not follow NASDAQ’s Rule 5620(c), which provides that the minimum quorum requirement for a meeting of shareholders is 33 ¹ ⁄ ₃ % of the outstanding common voting shares of the company. In accordance with the provisions of the French Commercial Code, the required majority for the adoption of a decision is a simple majority (for an ordinary general meeting of the shareholders) or a two-thirds majority (for an extraordinary general meeting) of the votes cast by the shareholders present or represented.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRMS

Report of Independent Registered Public Accounting Firms

To the Board of Directors and Shareholders of Sanofi,

Opinion on the Consolidated Financial Statements

We have audited the accompanying consolidated balance sheets of Sanofi and its subsidiaries (together the “Company”) as of December 31, 2019, 2018, and 2017, and the related consolidated income statements and consolidated statements of comprehensive income, changes in equity and cash flows for each of the three years in the period ended December 31, 2019, including the related notes (collectively referred to as the “consolidated financial statements”). In our opinion, the consolidated financial statements present fairly, in all material respects, the financial position of the Company as of December 31, 2019, 2018, and 2017, and the results of its operations and its cash flows for each of the three years in the period ended December 31, 2019, in conformity with International Financial Reporting Standards as issued by the International Accounting Standards Board and in conformity with International Financial Reporting Standards as endorsed by the European Union.

We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States) (“PCAOB”), the Company’s internal control over financial reporting as of December 31, 2019, based on criteria established in the Internal Control - Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (2013 framework) and our report dated March 5, 2020 expressed an unqualified opinion thereon.

Change in Accounting Principle

As discussed in Notes A.2.1 and D.17.2 to the consolidated financial statements, the Company changed the manner in which it accounts for leases in 2019.

Basis for Opinion

These consolidated financial statements are the responsibility of the Company’s management. Our responsibility is to express an opinion on the Company’s consolidated financial statements based on our audits. We are public accounting firms registered with the PCAOB and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.

We conducted our audits in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the consolidated financial statements are free of material misstatement, whether due to error or fraud. Our audits of the consolidated financial statements included performing procedures to assess the risks of material misstatement of the consolidated financial statements, whether due to error or fraud, and performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the consolidated financial statements. Our audits also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the consolidated financial statements. We believe that our audits provide a reasonable basis for our opinion.

Critical Audit Matters

The critical audit matters communicated below are matters arising from the current period audit of the consolidated financial statements that were communicated or required to be communicated to the audit committee and that: (1) relate to accounts or disclosures that are material to the consolidated financial statements and (2) involved our especially challenging, subjective or complex judgments. The communication of critical audit matters does not alter in any way our opinion on the consolidated financial statements, taken as a whole, and we are not, by communicating the critical audit matters below, providing separate opinions on the critical audit matters or on the accounts or disclosures to which they relate.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRMS

Recoverable amount of other intangible assets



Description of the Matter	Other intangible assets amounted to €16,572 million at December 31, 2019. Management recognized an impairment loss of €3,604 million for the year ended December 31, 2019. As described in Notes B.6.1., D.4. and D.5. to the consolidated financial statements, other intangible assets not yet available for use are tested for impairment annually and whenever events or circumstances indicate that impairment might exist. Other intangible assets that generate separate cash flows and assets included in cash-generating units (CGUs) are assessed for impairment when events or changes in circumstances indicate that the asset or CGU may be impaired. Management estimates the recoverable amount of the asset and recognizes an impairment loss if the carrying amount of the asset exceeds its recoverable amount. The recoverable amount of the asset is the higher of its fair value less costs to sell or its value in use.Value in use is determined by management using estimated future cash flows generated by the asset or CGU which are discounted and prepared using the same methods as those used in the initial measurement of the assets and on the basis of medium-term strategic plans. Management cash flow projections include significant assumptions related to mid and long-term sales forecasts; perpetual growth rate and attrition rate, where applicable; discount rate; and probability of success of current research and development projects. The principal considerations for our determination that auditing the recoverable amount of other intangible assets is especially challenging, subjective, and required complex auditor judgment related to the significant judgments made by management when developing the significant assumptions utilized in the future cash flow projections as described above. In addition, the audit effort involved professionals with specialized skill and knowledge to assist in performing the audit procedures and evaluating the audit evidence obtained.
How We Addressed the Matter in Our Audit	Addressing the matter involved performing procedures and evaluating audit evidence in connection with forming our overall opinion on the consolidated financial statements. These audit procedures included obtaining an understanding of the process and assessing the design and testing the operating effectiveness of controls relating to management’s other intangible assets impairment assessment, including controls over the significant assumptions used in the impairment testing of the other intangible assets. These audit procedures also included, among others, evaluating the appropriateness of the discounted cash flow model; testing the completeness, accuracy, and relevance of underlying data used in the model; and evaluating the significant assumptions used by management as described above. Evaluating management’s assumptions involved evaluating whether the assumptions used by management were reasonable by considering the current and past performance of other intangible assets in comparison to management’s previous forecasts and current trends, the consistency of forecasts and assumptions with external market and industry data, and whether these assumptions were consistent with evidence obtained in other areas of the audit such as internal company communications and presentations, external communications and analyst reports. We involved professionals with specialized skill and knowledge to assist in the evaluation of the discount rate.

Valuation of the discounts relating to Sanofi’s business in the United States - Medicaid, Medicare and Managed Care Rebates



Description of the Matter	As described in Notes B.13.1. and D.23. to the consolidated financial statements, products sold in the United States are covered by various Government and State programs (of which Medicaid and Medicare are the most significant) and are subject to commercial agreements with healthcare authorities and certain customers and distributors. Estimates of discounts and rebates incentives (hereinafter the “Discounts”) to be provided to customers under those arrangements are recognized as a reduction of gross sales in the period in which the underlying sales are recognized. Provisions for the Medicaid, Medicare and Managed Care rebates amounted to €1,017 million, €810 million and €649 million respectively at December 31, 2019. The Discounts estimated by management are based on the nature and patient profile of the underlying product; the applicable regulations or the specific terms and conditions of contracts with governmental authorities, wholesalers and other customers; historical data relating to similar contracts, in the case of qualitative and quantitative rebates; past experience and sales growth trends for the same or similar products; actual inventory levels in distribution channels, monitored by Sanofi using internal sales data and externally provided data; market trends including competition, pricing and demand. The principal considerations for our determination that auditing the Discounts relating to the Company’s business in the United States is especially challenging and required complex auditor judgment related to the significant judgment by management due to significant measurement uncertainty involved in developing these provisions. These provisions are estimated based on multiple factors as described above.
How We Addressed the Matter in Our Audit	Addressing the matter involved performing procedures and evaluating audit evidence in connection with forming our overall opinion on the consolidated financial statements. These audit procedures included obtaining an understanding of the process and assessing the design and testing the operating effectiveness of controls relating to management’s estimates of the provisions for the Discounts relating to the Company’s business in the United States, including controls over the assumptions used to estimate these Discounts. These procedures also included, among others, developing an independent estimate of the Discounts by utilizing third party data on inventory levels in distribution channels, volume, changes to price, the terms of the specific rebate programs, and the historical trend of actual rebate claims paid. The independent estimate was compared to the rebate accruals recorded by the Company. Additionally, these procedures included testing actual rebate claims paid and evaluating the contractual terms of the Company’s rebate agreements.




SANOFI / FORM 20-F 2019	177

Provisions for product liability risks, litigation and other, and contingent liabilities



Description of the Matter	Provisions for product liability risks, litigation and other were recorded in an amount of €1,344 million as at December 31, 2019. As described in Notes B.12., D.19.3. and D.22. to the consolidated financial statements, the Company records such provisions when an outflow of resources is probable and the amount of the outflow can be reliably estimated. The Company also discloses the contingent liabilities in circumstances where management is unable to make a reasonable estimate of the expected financial effect that will result from ultimate resolution of the proceeding, or a cash outflow is not probable. The pharmaceutical industry is highly regulated, which increases the inherent risk of litigation and arbitration. The Company is involved in litigation, arbitration and other legal proceedings. These proceedings are typically related to litigation concerning civil liability, intellectual property rights, competition law and trade practices, as well as claims under warranties or indemnification arrangements relating to business divestments. The issues raised by these claims are complex and subject to substantial uncertainties; therefore, the probability of loss and an estimation of damages are difficult to ascertain. The principal considerations for our determination that auditing the provision for product liability, litigation and other risks is especially challenging, subjective and required complex auditor judgment resulted from the determination that the measurement of the provisions can involve a series of complex judgments about future events and can rely substantially on estimates and assumptions by management. However, there is inherent uncertainty related to these cases and in estimating the likelihood and outcome of the cases.
How We Addressed the Matter in Our Audit	Addressing the matter involved performing procedures and evaluating audit evidence in connection with forming our overall opinion on the consolidated financial statements. These audit procedures included obtaining an understanding of the process and assessing the design and testing the operating effectiveness of controls relating to management’s evaluation of the provisions for product liability, litigation and other risks, including controls over determining whether a loss is probable and whether the amount of loss can be reasonably estimated, as well as the need for and the level of disclosures. These procedures also included, among others, obtaining and evaluating the letters of audit inquiry with internal and external legal counsel, evaluating management’s assessment regarding whether an unfavorable outcome is reasonably possible or probable and reasonably estimable through the evaluation of the legal letters and summaries of the proceedings and lawsuit correspondence, and evaluating the Company’s disclosures for contingent liabilities.

Uncertain tax positions



Description of the Matter	As described in Notes B.22., D.14, D.19.4. and D.30. to the consolidated financial statements, the Company has recorded tax liabilities for uncertain tax positions of €1,031 million as of December 31, 2019. The Company operates in multiple tax jurisdictions, carrying out potentially complex transactions that require management to make judgments and estimates as to the tax impact of those transactions. The positions adopted by the Company in tax matters are based on its interpretation of tax laws and regulations. Some of those positions may be subject to uncertainty. In such cases, the Company assesses the amount of the tax liability on the basis of the following assumptions: that its position will be examined by one or more tax authorities on the basis of all relevant information; that a technical assessment is carried out with reference to legislation, case law, regulations, and established practice; and each of its positions are assessed, with no offset or aggregation between positions. Those assumptions are assessed on the basis of facts and circumstances existing at the end of the reporting period. When an uncertain tax liability is regarded as probable, it is measured on the basis of the Company’s best estimate. The principal considerations for our determination that auditing uncertain tax positions is especially challenging, subjective and required complex auditor judgment related to the significant judgment by management when determining the liability for uncertain tax positions, including a high degree of estimation uncertainty of certain assumptions and interpretations of the tax laws and regulations underlying the positions. In addition, we involved tax professionals to assist in performing these procedures and evaluating the audit evidence obtained.
How We Addressed the Matter in Our Audit	Addressing the matter involved performing procedures and evaluating audit evidence in connection with forming our overall opinion on the consolidated financial statements. These audit procedures included obtaining an understanding of the process and assessing the design and testing the operating effectiveness of controls relating to the identification and recognition of the liability for uncertain tax positions, management’s assessment and interpretation of tax laws and its evaluation of which tax positions may not be sustained upon audit and controls over measurement of the liability. These procedures also included, among others, testing the completeness and accuracy of the underlying data used in the calculation of the liability for uncertain tax positions and evaluating the assumptions used by management when determining its tax positions, the status of any tax audits and investigations, and the potential impact of past claims. Tax professionals assisted in evaluating the reasonableness of management’s assessments by comparing the positions taken by management with tax regulations and past decisions from tax authorities and where applicable, evaluating opinions from the Company’s external tax advisors. We also evaluated the disclosures provided in the notes to the consolidated financial statements concerning uncertain tax positions.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRMS

Report of Independent Registered Public Accounting Firms

To the Board of Directors and Shareholders of Sanofi,

Opinion on Internal Control over Financial Reporting

We have audited Sanofi and its subsidiaries’ (together the “Company”) internal control over financial reporting as of December 31, 2019, based on criteria established in Internal Control - Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (2013 Framework) (the “COSO criteria”). In our opinion, the Company maintained, in all material respects, effective internal control over financial reporting as of December 31, 2019, based on the COSO criteria.

We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States) (PCAOB), the consolidated balance sheets of the Company as of December 31, 2019, 2018 and 2017, and the related consolidated income statements and consolidated statements of comprehensive income, changes in equity and cash flows for each of the three years in the period ended December 31, 2019, including the related notes (collectively referred to as the “consolidated financial statements”). Our report dated March 5, 2020 expressed an unqualified opinion thereon.

Basis for Opinion

The Company’s management is responsible for maintaining effective internal control over financial reporting and for its assessment of the effectiveness of internal control over financial reporting included in the accompanying Report of Management on Internal Control Over Financial Reporting. Our responsibility is to express an opinion on the Company’s internal control over financial reporting based on our audit. We are public accounting firms registered with the PCAOB and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.

We conducted our audit in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether effective internal control over financial reporting was maintained in all material respects.

Our audit included obtaining an understanding of internal control over financial reporting, assessing the risk that a material weakness exists, testing and evaluating the design and operating effectiveness of internal control based on the assessed risk, and performing such other procedures as we considered necessary in the circumstances. We believe that our audit provides a reasonable basis for our opinion.

Definition and Limitations of Internal Control Over Financial Reporting

A company’s internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. A company’s internal control over financial reporting includes those policies and procedures that (1) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the company; (2) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the company are being made only in accordance with authorizations of management and directors of the company; and (3) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of the company’s assets that could have a material effect on the financial statements.

Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.

NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS

Notes to the Consolidated Financial Statements

Introduction

Sanofi, together with its subsidiaries (collectively “Sanofi” or “the Company”), is a global healthcare leader engaged in the research, development and marketing of therapeutic solutions focused on patient needs.

Sanofi is listed in Paris (Euronext: SAN) and New York (Nasdaq: SNY).

The consolidated financial statements for the year ended December 31, 2019 , and the notes thereto, were signed off by the Sanofi Board of Directors on February 5, 2020.

A/ Basis of preparation

A.1. International financial reporting standards (IFRS)

The consolidated financial statements cover the twelve-month periods ended December 31, 2019 , 2018 and 2017 .

In accordance with Regulation No. 1606/2002 of the European Parliament and Council of July 19, 2002 on the application of international accounting standards, Sanofi has presented its consolidated financial statements in accordance with IFRS since January 1, 2005. The term “IFRS” refers collectively to international accounting and financial reporting standards (IASs and IFRSs) and to interpretations of the interpretations committees (SIC and IFRIC) with mandatory application as of December 31, 2019.

The consolidated financial statements of Sanofi as of December 31, 2019 have been prepared in compliance with IFRS as issued by the International Accounting Standards Board (IASB) and with IFRS as endorsed by the European Union as of December 31, 2019 ^(a) .

IFRS as endorsed by the European Union as of December 31, 2019 are available under the heading “IFRS Financial Statements” via the following web link:

https://www.efrag.org/Endorsement.

The consolidated financial statements have been prepared in accordance with the IFRS general principles of fair presentation, going concern, accrual basis of accounting, consistency of presentation, materiality, and aggregation.

A.2. New standards, amendments and interpretations

A.2.1. New standards applicable from January 1, 2019

IFRS 16 became applicable on January 1, 2019, requiring Sanofi to update its lease accounting policies as described in Note B.5., "Property, plant and equipment owned and leased". Most of the leases contracted by Sanofi relate to industrial and office premises, cars, and various items of plant and equipment, with Sanofi as the lessee.

Under IAS 17, most of the leases contracted by Sanofi were classified as operating leases in which Sanofi was the lessee.

For most of those leases, the first-time application of IFRS 16 effective January 1, 2019 has resulted in the recognition on the balance sheet of (i) a liability for future lease payments and (ii) a right-of-use asset. IFRS 16 has also led to the following changes in presentation:


▪	Balance sheet: Sanofi now presents right-of-use assets, non-current lease liabilities and current lease liabilities as separate line items.


▪	Income statement: the rental expense previously recognized as a component of Operating income is now presented partly as Depreciation expense (within Operating income ) , and partly within Financial expenses .


▪	In the statement of cash flows: the rental payments previously presented within Net cash provided by/(used in) operating activities are now presented within Net cash provided by/(used in) financing activities to the extent that those payments are allocated to repayment of the lease liability.

Sanofi has elected the simplified retrospective method for first-time application of IFRS 16, which involves recognizing a right-of-use asset equal to the amount of the lease liability. Under that method, comparative periods are not restated.

Consequently, for all leases (other than short-term leases and leases of low-value assets), a right-of-use asset was recognized on the balance sheet for an amount equal to the liability for future lease payments, adjusted by the amount of any prepaid or accrued lease payments. Amounts previously recognized in the financial statements for leases classified as finance leases under IAS 17 have remained unchanged. However, they have been reclassified from Property, plant and equipment to Right-of-use assets .

The lease liability recognized as of January 1, 2019 has been discounted at an average incremental borrowing rate of 3.5 % .


(a)	Sanofi has also early adopted, with effect from January 1, 2019, the amendment to IFRS 9 on interest rate benchmark reform, which was endorsed by the European Union between the end of the reporting period and the date on which the financial statements were closed off (see Note A.2.2).




SANOFI / FORM 20-F 2019	F-11

NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS – (Continued)

Sanofi has applied the following practical expedients available under IFRS 16 at the transition date:


▪	Leases with a lease term that ends between January 1, 2019 and December 31, 2019 have been treated as short-term leases and have not been capitalized, except for vehicle fleet leases.


▪	Initial direct costs have been excluded from the initial measurement of the right-of-use asset.


▪	The carrying amount of the right-of-use asset has not been subject to impairment testing under IAS 36, because it is regarded as having already been tested as part of a review of onerous contracts conducted under IAS 37 at a date close to the date of first-time application.

Finally, Sanofi has not identified any material embedded leases within service or supply contracts.

(a) Debits are shown as positive amounts and credits as negative amounts.

Due to the first-time application of IFRS 16 effective January 1, 2019, future commitments under operating leases are from that date recognized as part of the lease liability. Because Sanofi used the modified retrospective approach for transition, historical information has not been restated. However, as the prior standard (IAS 17) was applicable in preceding periods, commitments under operating leases are presented in the table below:



(€ million)	2018	2017

(a)	Mainly relates to a new lease contracted in the United States that will commence in 2021.

Repayments of the undiscounted lease liability as of January 1, 2019 break down as follows: 17 % within less than 1 year, 44 % between 1 and 5 years, 39 % after more than 5 years.

There was no material change in right-of-use assets between January 1, 2019 and December 31, 2019.

Following the IFRIC agenda decision of November 2019, Sanofi reviewed the lease term of contracts that are cancellable without the payment of a penalty, either by the lessor or the lessee, in order to take into account the concept of "economic penalty". This review resulted in a revision in the estimated end date of a lease in Germany, extending the lease term by 10 years.

As regards IFRIC 23 (Uncertainty over Income Tax Treatments), which was mandatorily applicable from January 1, 2019, Sanofi elected to early adopt this interpretation effective January 1, 2018.

NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS – (Continued)

A.2.2. New pronouncements issued by the IASB and applicable from 2020 or later

This note describes standards, amendments and interpretations issued by the IASB that will have mandatory application in 2020 or subsequent years, and Sanofi’s position regarding future application.

During 2018, the IASB published a number of amendments mandatorily applicable from January 1, 2020 onwards (subject to endorsement by the European Union), which Sanofi does not expect to have a material effect. These include “Definition of a Business” (amendment to IFRS 3), issued October 22, 2018, which will apply prospectively to business combinations from January 1, 2020 onwards. Sanofi has not early adopted any of those amendments in the consolidated financial statements for the year ended December 31, 2019.

On September 26, 2019, the IASB issued an amendment to IFRS 9 relating to interest rate benchmark reform. Sanofi has early adopted that amendment in the consolidated financial statements for the year ended December 31, 2019. The h edging instruments contracted by Sanofi affected by interest rate benchmark reform are the interest rate swaps described in note D.20b), maturing from 2022.

Fair value hedging relationships consist of swapping fixed-rate euro-denominated bonds to the overnight benchmark rate applicable in euros (Eonia), with a perfect alignment of critical terms between hedged items and hedging instruments. Consequently, those hedging relationships currently have no ineffective portion, and that will remain the case once Eonia is replaced by Ester, the new euro overnight benchmark rate.

Cash flow hedging relationships consist of swapping floating-rate synthetic debt (combination of fixed-rate bonds and fixed-to-Eonia interest rate swaps) to fixed rates, with the same perfect alignment of critical terms between hedged items and hedging instruments. Sanofi expects that Eonia will be replaced by Ester simultaneously in the interest rate swap contracts affected, and hence believes that the cash flow hedging relationships in question will remain fully effective. Consequently, Sanofi does not expect the interest rate benchmark reform to have a material impact on its hedging relationships.

A.3. Use of estimates and judgments

The preparation of financial statements requires management to make reasonable estimates and assumptions based on information available at the date of the finalization of the financial statements. Those estimates and assumptions may affect the reported amounts of assets, liabilities, revenues and expenses in the financial statements, and disclosures of contingent assets and contingent liabilities as of the date of the review of the financial statements. Examples of estimates and assumptions include:


▪	a mounts deducted from sales for projected sales returns, chargeback incentives, rebates and price reductions (see Notes B.13.1. and D.23.);


▪	impairment of property, plant and equipment, intangible assets, and investments accounted for using the equity method (see Notes B.6. and D.5.);


▪	the valuation of goodwill and the valuation and estimated useful life of acquired intangible assets (see Notes B.3.2., B.4.3., D.4. and D.5.);


▪	the measurement of equity investments in unquoted entities (see Notes B.8.5. and D.12.);


▪	the measurement of contingent consideration receivable in connection with asset divestments (see Notes B.8.5. and D.12.) and of contingent consideration payable (see Notes B.3. and D.18.);


▪	the measurement of financial assets at amortized cost (see Note B.8.5.);


▪	the amount of post-employment benefit obligations (see Notes B.23. and D.19.1.);


▪	the amount of provisions for restructuring, litigation, tax risks (other than those related to income taxes) and environmental risks (see Notes B.12., B.19., B.20., D.19. and D.22.); and


▪	the amount of deferred tax assets resulting from tax losses available for carry-forward and deductible temporary differences (see Notes B.22. and D.14.).

Actual results could differ from these estimates.

A.4. Hyperinflation

Under IAS 29, (Financial Reporting in Hyperinflationary Economies), non-monetary balance sheet items must be restated using a general price index; monetary items are not restated. Items in the income statement and the statement of comprehensive income must be restated by applying the change in the general price index from the dates when the income and expense items were initially recorded in the financial statements.

In 2019 , Sanofi continued to account for subsidiaries based in Venezuela using the full consolidation method, on the basis that the criteria for control as specified in IFRS 10 (Consolidated Financial Statements) are still met.

In 2018, the Venezuelan government made further changes to the foreign exchange system. At the end of August 2018 the “DICOM” rate, which had been the compulsory rate since the end of January 2018, was abolished and replaced by the “PETRO” rate with a floating US dollar/bolivar parity. At the same time, the strong bolivar (“VEF”) was also replaced by a new currency known as the sovereign bolivar (“VES”), reflecting a 1-for-100,000 devaluation. Consequently, the contribution of the Venezuelan subsidiaries to the consolidated financial statements is immaterial.

In Argentina, the cumulative rate of inflation over the last three years is in excess of 100 % , based on a combination of indices used to measure inflation in that country. Consequently, Sanofi has treated Argentina as a hyperinflationary economy from July 1, 2018 onwards, and applies IAS 29. As a result, an immaterial monetary foreign exchange loss was recognized in the Sanofi financial statements as of December 31, 2019 and December 31, 2018 in respect of the impact of hyperinflation in Argentina.




SANOFI / FORM 20-F 2019	F-13

NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS – (Continued)

A.5. Withdrawal of the United Kingdom from the European Union

The announced withdrawal of the United Kingdom from the European Union does not pose any major issues for Sanofi, and Sanofi does not expect a material impact on the consolidated financial statements.

B/ Summary of significant accounting policies

B.1. Basis of consolidation

In accordance with IFRS 10 (Consolidated Financial Statements), the consolidated financial statements of Sanofi include the financial statements of entities that Sanofi controls directly or indirectly, regardless of the level of the equity interest in those entities. An entity is controlled when Sanofi has power over the entity, exposure or rights to variable returns from its involvement with the entity, and the ability to affect those returns through its power over the entity. In determining whether control exists, potential voting rights must be taken into account if those rights are substantive, in other words they can be exercised on a timely basis when decisions about the relevant activities of the entity are to be taken.

Entities consolidated by Sanofi are referred to as “subsidiaries”. Entities that Sanofi controls by means other than voting rights are referred to as “consolidated structured entities”.

In accordance with IFRS 11 (Joint Arrangements), Sanofi classifies its joint arrangements (i.e. arrangements in which Sanofi exercises joint control with one or more other parties) either as a joint operation or a joint venture. In the case of a joint operation, Sanofi recognizes the assets and liabilities of the operation in proportion to its rights and obligations relating to those assets and liabilities. Joint ventures are accounted for using the equity method.

Sanofi exercises joint control over a joint arrangement when decisions relating to the relevant activities of the arrangement require the unanimous consent of Sanofi and the other parties with whom control is shared.

Sanofi exercises significant influence over an entity when it has the power to participate in the financial and operating policy decisions of that entity, but does not have the power to exercise control or joint control over those policies.

In accordance with IAS 28 (Investments in Associates and Joint Ventures), the equity method is used to account for joint ventures (i.e. entities over which Sanofi exercises joint control) and for associates (i.e. entities over which Sanofi exercises significant influence).

Under the equity method, the investment is initially recognized at cost, and subsequently adjusted to reflect changes in the net assets of the associate or joint venture. IAS 28 does not specify the treatment to be adopted on first-time application of the equity method to an investee following a step acquisition. Consequently, by reference to paragraph 10 of IAS 28, Sanofi has opted to apply the cost method, whereby the carrying amount of the investment represents the sum of the historical cost amounts for each step in the acquisition. As of the date on which the equity method is first applied, goodwill (which is included in the carrying amount of the investment) is determined for each acquisition step. The same applies to subsequent increases in the percentage interest in the equity-accounted investment.

When the criteria of IFRS 5 are met, Sanofi recognizes the equity interest within the balance sheet line item Assets held for sale or exchange . The equity method is not applied to equity interests that are classified as held-for-sale assets.

Transactions between consolidated companies are eliminated, as are intragroup profits.

A list of the principal companies included in the consolidation in 2019 is presented in Note F.

B.2. Foreign currency translation

B.2.1. Accounting for foreign currency transactions in the financial statements of consolidated entities

Non-current assets (other than receivables) and inventories acquired in foreign currencies are translated into the functional currency using the exchange rate prevailing at the acquisition date.

Monetary assets and liabilities denominated in foreign currencies are translated using the exchange rate prevailing at the end of the reporting period. The gains and losses resulting from foreign currency translation are recorded in the income statement. However, foreign exchange gains and losses arising from the translation of advances between consolidated subsidiaries for which settlement is neither planned nor likely to occur in the foreseeable future are recognized in equity, in the line item Change in currency translation differences .

B.2.2. Foreign currency translation of the financial statements of foreign entities

Sanofi presents its consolidated financial statements in euros (€). In accordance with IAS 21 (The Effects of Changes in Foreign Exchange Rates), each subsidiary accounts for its transactions in the currency that is most representative of its economic environment (the functional currency).

All assets and liabilities are translated into euros using the exchange rate of the subsidiary’s functional currency prevailing at the end of the reporting period. Income statements are translated using a weighted average exchange rate for the period, except in the case of foreign subsidiaries in a hyperinflationary economy. The resulting currency translation difference is recognized as a separate component of equity in the consolidated statement of comprehensive income, and is recognized in the income statement only when the subsidiary is sold or is wholly or partially liquidated.




F-14	SANOFI / FORM 20-F 2019

NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS – (Continued)

B.3. Business combinations and transactions with non-controlling interests

B.3.1. Accounting for business combinations, transactions with non-controlling interests and loss of control

Business combinations are accounted for in accordance with IFRS 3 (Business Combinations) and IFRS 10 (Consolidated Financial Statements).

Business combinations are accounted for using the acquisition method. Under this method, the acquiree’s identifiable assets and liabilities that satisfy the recognition criteria of IFRS 3 (Business Combinations) are measured initially at their fair values as at the date of acquisition, except for (i) non-current assets classified as held for sale (which are measured at fair value less costs to sell) and (ii) assets and liabilities that fall within the scope of IAS 12 (Income Taxes) and IAS 19 (Employee Benefits). Restructuring liabilities are recognized as a liability of the acquiree only if the acquiree has an obligation as of the acquisition date to carry out the restructuring.

The principal accounting rules applicable to business combinations and transactions with non-controlling interests include:


▪	Acquisition-related costs are recognized as an expense on the acquisition date, as a component of Operating income .

▪

Contingent consideration is recognized in equity if the contingent payment is settled by delivery of a fixed number of the acquirer’s equity instruments; otherwise, it is recognized in Liabilities related to business combinations . Contingent consideration is recognized at fair value at the acquisition date irrespective of the probability of payment. If the contingent consideration was originally recognized as a financial liability, subsequent adjustments to the liability are recognized in profit or loss in the line item Fair value remeasurement of contingent consideration , unless the adjustment is made within the twelve months following the acquisition date and relates to facts and circumstances existing as of that date. Subsequent contingent consideration adjustments in respect of business combinations completed before January 1, 2010 continue to be accounted for in accordance with IFRS 3 (i.e. through goodwill).


▪	Goodwill may be calculated on the basis of either (i) the entire fair value of the acquiree, or (ii) a share of the fair value of the acquiree proportionate to the interest acquired. This option may be elected for each acquisition individually.

Purchase price allocations are performed under the responsibility of management, with assistance from an independent valuer in the case of major acquisitions. IFRS 3 does not specify an accounting treatment for contingent consideration arising from a business combination made by an entity prior to the acquisition of control in that entity and carried as a liability in the acquired entity’s balance sheet. The accounting treatment applied by Sanofi to such a liability is to measure it at fair value as of the acquisition date and to report it in the line item Liabilities related to business combinations and to non-controlling interests , with subsequent remeasurements recognized in profit or loss. This treatment is consistent with the accounting applied to contingent consideration in the books of the acquirer.

B.3.2. Goodwill

The excess of the cost of an acquisition over Sanofi’s interest in the fair value of the identifiable assets and liabilities of the acquiree is recognized as goodwill at the date of the business combination.

Goodwill arising on the acquisition of subsidiaries is shown in a separate balance sheet line item, whereas goodwill arising on the acquisition of investments accounted for using the equity method is recorded in Investments accounted for using the equity method .

Goodwill arising on foreign operations is expressed in the functional currency of the country concerned and translated into euros using the exchange rate prevailing at the end of the reporting period.

In accordance with IAS 36 (Impairment of Assets), goodwill is carried at cost less accumulated impairment (see Note B.6.).

Goodwill is tested for impairment annually and whenever events or circumstances indicate that impairment might exist. Such events or circumstances include significant changes more likely than not to have an other-than-temporary impact on the substance of the original investment.

B.4. Other intangible assets

Other intangible assets are initially measured at acquisition cost or production cost, including any directly attributable costs of preparing the asset for its intended use, or (in the case of assets acquired in a business combination) at fair value as of the date of the business combination. Intangible assets are amortized on a straight line basis over their useful lives.

The useful lives of other intangible assets are reviewed at the end of each reporting period. The effect of any adjustment to useful lives is recognized prospectively as a change in accounting estimate.

Amortization of other intangible assets is recognized in the income statement within Amortization of intangible assets except for amortization charged against (i) acquired or internally-developed software and (ii) other rights of an industrial or operational nature, which is recognized in the relevant classification of expense by function.

Sanofi does not own any intangible assets with an indefinite useful life, other than goodwill.

Intangible assets (other than goodwill) are carried at cost less accumulated amortization and accumulated impairment, if any, in accordance with IAS 36 (see Note B.6.).

B.4.1. Research and development not acquired in a business combination

Internally generated research and development

Under IAS 38, research expenses are recognized in profit or loss when incurred.




SANOFI / FORM 20-F 2019	F-15

NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS – (Continued)

Internally generated development expenses are recognized as an intangible asset if, and only if, all the following six criteria can be demonstrated: (a) the technical feasibility of completing the development project; (b) Sanofi’s intention to complete the project; (c) Sanofi’s ability to use the project; (d) the probability that the project will generate future economic benefits; (e) the availability of adequate technical, financial and other resources to complete the project; and (f) the ability to measure the development expenditure reliably.

Due to the risks and uncertainties relating to regulatory approval and to the research and development process, the six criteria for capitalization are usually considered not to have been met until the product has obtained marketing approval from the regulatory authorities. Consequently, internally generated development expenses arising before marketing approval has been obtained, mainly the cost of clinical trials, are generally expensed as incurred within Research and development expenses .

Some industrial development expenses (such as those incurred in developing a second-generation synthesis process) are incurred after marketing approval has been obtained, in order to improve the industrial process for an active ingredient. To the extent that the six IAS 38 criteria are considered as having been met, such expenses are recognized as an asset in the balance sheet within Other intangible assets as incurred. Similarly, some clinical trials, for example those undertaken to obtain a geographical extension for a molecule that has already obtained marketing approval in a major market, may in certain circumstances meet the six capitalization criteria under IAS 38, in which case the related expenses are recognized as an asset in the balance sheet within Other intangible assets .

Separately acquired research and development

Payments for separately acquired research and development are capitalized within Other intangible assets provided that they meet the definition of an intangible asset: a resource that is (i) controlled by Sanofi, (ii) expected to provide future economic benefits for Sanofi, and (iii) identifiable (i.e. it is either separable or arises from contractual or legal rights). Under paragraph 25 of IAS 38, the first condition for capitalization (the probability that the expected future economic benefits from the asset will flow to the entity) is considered to be satisfied for separately acquired research and development. Consequently, upfront and milestone payments to third parties related to pharmaceutical products for which marketing approval has not yet been obtained are recognized as intangible assets, and amortized on a straight line basis over their useful lives beginning when marketing approval is obtained.

Payments under research and development arrangements relating to access to technology or to databases and payments made to purchase generics dossiers are also capitalized, and amortized over the useful life of the intangible asset.

Subcontracting arrangements, payments for research and development services, and continuous payments under research and development collaborations which are unrelated to the outcome of that collaboration, are expensed over the service term.

B.4.2. Other intangible assets not acquired in a business combination

Licenses other than those related to pharmaceutical products and research projects, in particular software licenses, are capitalized at acquisition cost, including any directly attributable cost of preparing the software for its intended use. Software licenses are amortized on a straight line basis over their useful lives for Sanofi ( three to five years ).

Internally generated costs incurred to develop or upgrade software are capitalized if the IAS 38 recognition criteria are satisfied, and amortized on a straight line basis over the useful life of the software from the date on which the software is ready for use.

B.4.3. Other intangible assets acquired in a business combination

Other intangible assets acquired in a business combination which relate to in-process research and development and currently marketed products and are reliably measurable are identified separately from goodwill, measured at fair value and capitalized within Other intangible assets in accordance with IFRS 3 (Business Combinations) and IAS 38 (Intangible Assets). The related deferred tax liability is also recognized if a deductible or taxable temporary difference exists.

In-process research and development acquired in a business combination is amortized on a straight line basis over its useful life from the date of receipt of marketing approval.

Rights to products currently marketed by Sanofi are amortized on a straight line basis over their useful lives, determined on the basis of cash flow forecasts which take into account the patent protection period of the marketed product.

B.5. Property, plant and equipment owned and leased

B.5.1 Property, plant and equipment owned

Property, plant and equipment is initially measured and recognized at acquisition cost, including any directly attributable cost of preparing the asset for its intended use, or (in the case of assets acquired in a business combination) at fair value as of the date of the business combination. The component-based approach to accounting for property, plant and equipment is applied. Under this approach, each component of an item of property, plant and equipment with a cost which is significant in relation to the total cost of the item and which has a different useful life from the other components must be depreciated separately.

After initial measurement, property, plant and equipment is carried at cost less accumulated depreciation and impairment, except for land which is carried at cost less impairment.

Subsequent costs are not recognized as assets unless (i) it is probable that future economic benefits associated with those costs will flow to Sanofi and (ii) the costs can be measured reliably.

Borrowing costs attributable to the financing of items of property, plant and equipment, and incurred during the construction period, are capitalized as part of the acquisition cost of the item.

Government grants relating to property, plant and equipment are deducted from the acquisition cost of the asset to which they relate.

The depreciable amount of items of property, plant and equipment, net of any residual value, is depreciated on a straight line basis over the useful life of the asset. The useful life of an asset is usually equivalent to its economic life.




F-16	SANOFI / FORM 20-F 2019

NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS – (Continued)

The customary useful lives of property, plant and equipment are as follows:



Buildings	15 to 40 years
Fixtures	10 to 20 years
Machinery and equipment	5 to 15 years
Other	3 to 15 years

Useful lives and residual values of property, plant and equipment are reviewed annually. The effect of any adjustment to useful lives or residual values is recognized prospectively as a change in accounting estimate.

Depreciation of property, plant and equipment is recognized as an expense in the income statement, in the relevant classification of expense by function.

B.5.2 Property, plant and equipment leased

Leases contracted by Sanofi are accounted for in accordance with IFRS 16 (Leases). Sanofi recognizes a right-of-use asset and a lease liability for all of its lease contracts, except for (i) leases relating to low-value assets and (ii) short-term leases (12 months or less). Payments made in respect of leases not recognized on the balance sheet are recognized as an operating expense on a straight line basis over the lease term.

On commencement of a lease, the liability for future lease payments is discounted at the incremental borrowing rate, which is a risk-free rate adjusted to reflect the specific risk profile of each Sanofi entity. Because lease payments are spread over the lease term, Sanofi applies a discount rate based on the duration of those payments.

The payments used to determine the liability for future lease payments exclude non-lease components, but include fixed payments that Sanofi expects to make to the lessor over the estimated lease term.

After commencement of the lease, the liability for future lease payments is reduced by the amount of the lease payments made, and increased to reflect interest on the liability. In the event of a reassessment or modification of future lease payments, the lease liability is remeasured. The right-of-use asset - which is initially measured at cost including direct costs of the lessee, prepayments made at or prior to the commencement date, less lease incentives received and restoration costs - is depreciated on a straight line basis over the lease term, and tested for impairment as required.

Sanofi recognizes deferred taxes in respect of right-of-use assets and lease liabilities.

Leasehold improvements are depreciated over their economic life, which is capped at the lease term as determined under IFRS 16.

B.6. Impairment of property, plant and equipment, intangible assets, and investments accounted for using the equity method

B.6.1. Impairment of property, plant and equipment and intangible assets

In accordance with IAS 36 (Impairment of Assets), assets that generate separate cash flows and assets included in cash-generating units (CGUs) are assessed for impairment when events or changes in circumstances indicate that the asset or CGU may be impaired. A CGU is the smallest identifiable group of assets that generates cash inflows that are largely independent of the cash inflows from other assets or groups of assets.

Under IAS 36, each CGU to which goodwill is allocated must (i) represent the lowest level within the entity at which the goodwill is monitored for internal management purposes, and (ii) not be larger than an operating segment determined in accordance with IFRS 8 (Operating Segments), before application of the IFRS 8 aggregation criteria (see Note B.26.).

Quantitative and qualitative indications of impairment (primarily relating to the status of the research and development portfolio, pharmacovigilance, patent litigation, and the launch of competing products) are reviewed at the end of each reporting period. If there is any internal or external indication of impairment, Sanofi estimates the recoverable amount of the asset or CGU.

Other intangible assets not yet available for use (such as capitalized in-process research and development), and CGUs that include goodwill, are tested for impairment annually whether or not there is any indication of impairment, and more frequently if any event or circumstance indicates that they might be impaired. Such assets are not amortized.

When there is an internal or external indication of impairment, Sanofi estimates the recoverable amount of the asset and recognizes an impairment loss if the carrying amount of the asset exceeds its recoverable amount. The recoverable amount of the asset is the higher of its fair value less costs to sell or its value in use. To determine value in use, Sanofi uses estimates of future cash flows generated by the asset or CGU, prepared using the same methods as those used in the initial measurement of the asset or CGU on the basis of medium-term strategic plans.

In the case of goodwill, estimates of future cash flows are based on a medium-term strategic plan, an extrapolation of the cash flows beyond that plan, and a terminal value. In the case of other intangible assets, the period used is based on the economic life of the asset.

Estimated cash flows are discounted at long-term market interest rates that reflect the best estimate by Sanofi of the time value of money, the risks specific to the asset or CGU, and economic conditions in the geographical regions in which the business activity associated with the asset or CGU is located.

Certain assets and liabilities that are not directly attributable to a specific CGU are allocated between CGUs on a basis that is reasonable, and consistent with the allocation of the corresponding goodwill.




SANOFI / FORM 20-F 2019	F-17

NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS – (Continued)

Impairment losses arising on property, plant and equipment, on software and on certain rights are recognized in the relevant classification of expense by function.

Impairment losses arising on other intangible assets are recognized within Impairment of intangible assets in the income statement.

B.6.2. Impairment of investments accounted for using the equity method

In accordance with IAS 28 (Investments in Associates and Joint Ventures), Sanofi determines whether investments accounted for using the equity method may be impaired based on indicators such as default in contractual payments, significant financial difficulties, probability of bankruptcy, or a prolonged or significant decline in quoted market price. If an investment is impaired, the amount of the impairment loss is determined by applying IAS 36 (see Note B.6.1.) and recognized in Share of profit/(loss) from investments accounted for using the equity method .

B.6.3. Reversals of impairment losses charged against property, plant and equipment, intangible assets, and investments accounted for using the equity method

At the end of each reporting period, Sanofi assesses whether events or changes in circumstances indicate that an impairment loss recognized in a prior period in respect of an asset (other than goodwill) or an investment accounted for using the equity method can be reversed. If this is the case, and the recoverable amount as determined based on the revised estimates exceeds the carrying amount of the asset, Sanofi reverses the impairment loss only to the extent of the carrying amount that would have been determined had no impairment loss been recognized for the asset.

Reversals of impairment losses in respect of other intangible assets are recognized within the income statement line item Impairment of intangible assets , while reversals of impairment losses in respect of investments accounted for using the equity method are recognized within the income statement line item Share of profit/(loss) from investments accounted for using the equity method . Impairment losses taken against goodwill are never reversed, unless the goodwill is part of the carrying amount of an investment accounted for using the equity method.

B.7. Assets held for sale or exchange and liabilities related to assets held for sale or exchange

In accordance with IFRS 5 (Non-Current Assets Held for Sale and Discontinued Operations), non-current assets and groups of assets are classified as held for sale in the balance sheet if their carrying amount will be recovered principally through a sale transaction rather than through continuing use. Within the meaning of IFRS 5, the term “sale” also includes exchanges for other assets.

Non-current assets or asset groups held for sale must be available for immediate sale in their present condition, subject only to terms that are usual and customary for sales of such assets, and a sale must be highly probable. Criteria used to determine whether a sale is highly probable include:


▪	the a ppropriate level of management must be committed to a plan to sell;


▪	an active program to locate a buyer and complete the plan must have been initiated;


▪	the asset mu st be actively marketed for sale at a price that is reasonable in relation to its current fair value;


▪	completion of the sale should be foreseeable within the twelve months following the date of reclassification to Assets held for sale or exchange ; and


▪	actions required to complete the plan should indicate that it is unlikely that significant changes to the plan will be made or that the plan will be withdrawn.

Before initial reclassification of the non-current asset (or asset group) to Assets held for sale or exchange , the carrying amounts of the asset (or of all the assets and liabilities in the asset group) must be measured in accordance with the applicable standards.

Subsequent to reclassification to Assets held for sale or exchange , the non-current asset (or asset group) is measured at the lower of carrying amount or fair value less costs to sell, with any write-down recognized by means of an impairment loss. Once a non-current asset has been reclassified as held for sale or exchange, it is no longer depreciated or amortized.

In a disposal of an equity interest leading to loss of control, all the assets and liabilities of the entity involved are classified as held-for-sale assets or liabilities within the balance sheet line items Assets held for sale or exchange or Liabilities related to assets held for sale or exchange , provided that the disposal satisfies the IFRS 5 classification criteria.

The profit or loss generated by a held-for-sale asset group is reported in a separate line item in the income statement for the current period and for the comparative periods presented, provided that the asset group:


▪	represen ts a separate major line of business or geographical area of operations; or,


▪	is part of a single coordinated plan to dispose of a separate major line of business or geographical area of operations; or,


▪	is a subsidia ry acquired exclusively with a view to resale.

In accordance with IFRS 10, transactions between companies that are held for sale or treated as discontinued operations and other consolidated companies are eliminated.

Events or circumstances beyond Sanofi’s control may extend the period to complete the sale or exchange beyond one year without precluding classification of the asset (or disposal group) in Assets held for sale or exchange provided that there is sufficient evidence that Sanofi




F-18	SANOFI / FORM 20-F 2019

NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS – (Continued)

remains committed to the planned sale or exchange. Finally, in the event of changes to a plan of sale that requires an asset no longer to be classified as held for sale, IFRS 5 specifies the following treatment:


▪	The ass ets and liabilities previously classified as held for sale are reclassified to the appropriate balance sheet line items, with no restatement of comparative periods.


▪	Each asset is measured at the lower of (a) its carrying amount before the asset was reclassified as held for sale, adjusted for any depreciation, amortization or revaluation that would have been recognized if the asset had not been reclassified as held for sale, or (b) its recoverable a mount at the date of reclassification.

▪

The backlog of depreciation, amortization and impairment not recognized while non-current assets were classified as held for sale must be reported in the same income statement line item that was used to report impairment losses arising on initial reclassification of assets as held for sale and gains or losses arising on the sale of such assets. In the consolidated income statement, those impacts are reported within the line item Other gains and losses, and litigation.


▪	The net incom e of a business previously classified as discontinued or as held for sale or exchange and reported on a separate line in the income statement must be reclassified and included in net income from continuing operations, for all periods presented.


▪	In addition, segme nt information relating to the income statement and the statement of cash flows (acquisitions of non-current assets) must be disclosed in the notes to the financial statements in accordance with IFRS 8 (Operating Segments), and must also be restated for all prior periods presented.

B.8. Financial instruments

B.8.1. Non-derivative financial assets

In accordance with IFRS 9 (Financial Instruments) and IAS 32 (Financial Instruments: Presentation), Sanofi has adopted the classification of non-derivative financial assets described below. The classification used depends on (i) the characteristics of the contractual cash flows (i.e. whether they represent interest or principal) and (ii) the business model for managing the asset applied at the time of initial recognition.

Financial assets at fair value through other comprehensive income

These mainly comprise:

▪

quoted and unquoted equity investments that Sanofi does not hold for trading purposes and that management has designated at “fair value through other comprehensive income” on initial recognition. Gains and losses arising from changes in fair value are recognized in equity within the statement of comprehensive income in the period in which they occur. When such instruments are derecognized, the previously-recognized changes in fair value remain within Other comprehensive income , as does the gain or loss on divestment. Dividends received are recognized in profit or loss for the period, within the line item Financial income ; and

▪

debt instruments whose contractual cash flows represent payments of interest or repayments of principal, and which are managed with a view to collecting cash flows and selling the asset. Gains and losses arising from changes in fair value are recognized in equity within the statement of comprehensive income in the period in which they occur. When such assets are derecognized, the cumulative gains and losses previously recognized in equity are reclassified to profit or loss for the period within the line items Financial income or Financial expenses .

Financial assets at fair value through profit or loss

These mainly comprise:


▪	co ntingent consideration already carried in the books of an acquired entity or granted in connection with a business combination;


▪	instruments whose contractual cash flows represent payments of interest and repayments of principal, which are managed with a view to selling the asset;


▪	instruments that management has designated as ”fair value through profit or loss” on initial recognition; and


▪	quoted and unquoted equity investments: equity instruments that are not held for trading and which management did not designate at “fair value through o ther comprehensive income” on initial recognition, and instruments that do not meet the IFRS definition of “equity instruments”.

Gains and losses arising from changes in fair value are recognized in profit or loss within the line items Financial income or Financial expenses . Dividends received are recognized in profit or loss for the period, within the line item Financial income .

Fair value of equity investments in unquoted entities

On initial recognition of an equity investment in an entity not quoted in an active market, the fair value of the investment is the acquisition cost. Cost ceases to be a representative measure of the fair value of an unquoted equity investment when Sanofi identifies significant changes in the investee, or in the environment in which it operates. In such cases, an internal valuation is carried out, based mainly on growth forecasts or by reference to similar transactions contracted with third parties.

Financial assets measured at amortized cost

Financial assets at amortized cost comprise instruments whose contractual cash flows represent payments of interest and repayments of principal and which are managed with a view to collecting cash flows. The main assets in this category are loans and receivables. They are presented within the line items Other non-current assets , Other current assets , Accounts receivable and Cash and cash equivalents . Loans with a maturity of more than 12 months are presented in “Long-term loans and advances” within Other non-current assets . These financial assets are measured at amortized cost using the effective interest method.




SANOFI / FORM 20-F 2019	F-19

NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS – (Continued)

Impairment of financial assets measured at amortized cost

The main assets involved are accounts receivable.

Accounts receivable are initially recognized at the amount invoiced to the customer. Impairment losses on trade accounts receivable are estimated using the expected loss method, in order to take account of the risk of payment default throughout the lifetime of the receivables. The expected credit loss is estimated collectively for all accounts receivable at each reporting date using an average expected loss rate, determined primarily on the basis of historical credit loss rates. However, that average expected loss rate may be adjusted if there are indications of a likely significant increase in credit risk. If a receivable is subject to a known credit risk, a specific impairment loss is recognized for that receivable. The amount of expected losses is recognized in the balance sheet as a reduction in the gross amount of accounts receivable. Impairment losses on accounts receivable are recognized within Selling and general expenses in the income statement.

B.8.2. Derivative instruments

Derivative instruments that do not qualify for hedge accounting are initially and subsequently measured at fair value, with changes in fair value recognized in the income statement in Other operating income or in Financial income or Financial expenses , depending on the nature of the underlying economic item which is hedged.

Derivative instruments that qualify for hedge accounting are measured using the policies described in Note B.8.3. below.

IFRS 13 (Fair Value Measurement) requires counterparty credit risk to be taken into account when measuring the fair value of financial instruments. That risk is estimated on the basis of observable, publicly-available statistical data.

Policy on offsetting

In order for a financial asset and a financial liability to be presented as a net amount in the balance sheet under IAS 32, there must be:

(a) a legally enforceable right to offset; and

(b) the intention either to settle on a net basis, or to realize the asset and settle the liability simultaneously.

In addition, IFRS 7 (Financial Instruments: Disclosures) requires the notes to the financial statements to include a schedule showing a list of any offsets recognized under IAS 32 and of transactions for which only criterion (a) is met, i.e. potential offsets such as those specified in close out netting agreements (positions offset only in the event of default, as specified in the International Swaps and Derivatives Association (ISDA) standard).

B.8.3. Hedging

As part of its overall market risk management policy, Sanofi enters into various hedging transactions involving derivative or non-derivative instruments; these may include forward contracts, currency swaps or options, interest rate swaps or options, cross-currency swaps, and debt placings or issues.

Such financial instruments are designated as hedging instruments and recognized using the hedge accounting principles of IFRS 9 when (a) there is formal designation and documentation of the hedging relationship, of how the effectiveness of the hedging relationship will be assessed, and of the underlying market risk management objective and strategy; (b) the hedged item and the hedging instrument are eligible for hedge accounting; and (c) there is an economic relationship between the hedged item and the hedging instrument, defined on the basis of a hedge ratio that is consistent with the underlying market risk management strategy, and the residual credit risk does not dominate the value changes that result from that economic relationship.

Fair value hedge

A fair value hedge is a hedge of the exposure to changes in fair value of an asset, liability or firm commitment that is attributable to one or more risk components and could affect profit or loss.

Changes in fair value of the hedging instrument and changes in fair value of the hedged item attributable to the hedged risk components are generally recognized in the income statement, within Other operating income for hedges related to operating activities, or within Financial income or Financial expenses for hedges related to investing or financing activities.

Cash flow hedge

A cash flow hedge is a hedge of the exposure to variability in cash flows from an asset, liability or highly probable forecast transaction that is attributable to one or more risk components and could affect profit or loss.

Changes in fair value of the hedging instrument attributable to the effective portion of the hedge are recognized directly in equity in the consolidated statement of comprehensive income. Changes in fair value attributable to the ineffective portion of the hedge are recognized in the income statement within Other operating income for hedges related to operating activities, and within Financial income or Financial expenses for hedges related to investing or financing activities.

Cumulative changes in fair value of the hedging instrument previously recognized in equity are reclassified to the income statement when the hedged transaction affects profit or loss. Those reclassified gains and losses are recognized within Other operating income for hedges related to operating activities, and within Financial income or Financial expenses for hedges related to investing or financing activities.

When a forecast transaction results in the recognition of a non-financial asset or liability, cumulative changes in the fair value of the hedging instrument previously recognized in equity are incorporated in the initial carrying amount of that asset or liability .

When the hedging instrument expires or is sold, terminated or exercised, the cumulative gain or loss previously recognized in equity remains separately recognized in equity and is not reclassified to the income statement (or recognized as an adjustment to the initial cost of the related non-financial asset or liability) until the forecast transaction occurs. However, if Sanofi no longer expects the forecast transaction to occur, the cumulative gain or loss previously recognized in equity is recognized immediately in profit or loss.




F-20	SANOFI / FORM 20-F 2019

NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS – (Continued)

Hedge of a net investment in a foreign operation

In a hedge of a net investment in a foreign operation, changes in the fair value of the hedging instrument attributable to the effective portion of the hedge are recognized directly in equity in the consolidated statement of comprehensive income. Changes in fair value attributable to the ineffective portion of the hedge are recognized in the income statement within Financial income or Financial expenses . When the investment in the foreign operation is sold, the changes in the fair value of the hedging instrument previously recognized in equity are reclassified to the income statement within Financial income or Financial expenses .

Cost of hedging

As part of its market risk management policy, Sanofi may designate currency options or interest rate options as hedging instruments, the effectiveness of which is measured on the basis of changes in intrinsic value. In such cases, the time value of the option is treated as a hedging cost and accounted for as follows:


▪	If the option i ncludes a component that is not aligned on the critical features of the hedged item, the corresponding change in the time value is taken to profit or loss.


▪	Otherwise, the ch ange in the time value is taken to equity within the statement of comprehensive income, and then:


–	if the h edged item is linked to a transaction that results in the recognition of a financial asset or liability, the change in the time value is reclassified to profit or loss symmetrically with the hedged item; or,


–	if the hedged item is linked to a transaction that results in the recognition of a non-financial asset or liability, the change in the time value is incorporated in the initial carrying amount of that asset or liability; or,


–	if the hedged item is linked to a period of time, the change in time value is reclassified to profit or loss on a straight line basis over the life of the hedging relationship.

In the case of forward contracts and currency swaps, and of cross-currency swaps that qualify for hedge accounting on the basis of changes in spot rates, Sanofi may elect for each transaction to use the option whereby the premium/discount or foreign currency basis spread are treated in the same way as the time value of an option.

Discontinuation of hedge accounting

Hedge accounting is discontinued when the eligibility criteria are no longer met (in particular, when the hedging instrument expires or is sold, terminated or exercised), or if there is a change in the market risk management objective of the hedging relationship.

B.8.4. Non-derivative financial liabilities

Borrowings and debt

Bank borrowings and debt instruments are initially measured at fair value of the consideration received, net of directly attributable transaction costs.

Subsequently, they are measured at amortized cost using the effective interest method. All costs related to the issuance of borrowings or debt instruments, and all differences between the issue proceeds net of transaction costs and the value on redemption, are recognized within Financial expenses in the income statement over the term of the debt using the effective interest method.

Liabilities related to business combinations and to non-controlling interests

These line items record the fair value of (i) contingent consideration payable in connection with business combinations and (ii) commitments to buy out equity holders of subsidiaries, including put options granted to non-controlling interests.

Adjustments to the fair value of commitments to buy out equity holders of subsidiaries, including put options granted to non-controlling interests, are recognized in equity.

Other non-derivative financial liabilities

Other non-derivative financial liabilities include trade accounts payable, which are measured at fair value (which in most cases equates to face value) on initial recognition, and subsequently at amortized cost.

B.8.5. Fair value of financial instruments

Under IFRS 13 (Fair Value Measurement) and IFRS 7 (Financial Instruments: Disclosures), fair value measurements must be classified using a hierarchy based on the inputs used to measure the fair value of the instrument. This hierarchy has three levels:

(a) level 1: quoted prices in active markets for identical assets or liabilities (without modification or repackaging);

(b) level 2: quoted prices in active markets for similar assets and liabilities, or valuation techniques in which all important inputs are derived from observable market data; and

The fair value of such liabilities is determined by adjusting the contingent consideration at the end of the reporting period using the method described in Note B.11.


(a)	In the case of debt designated as a hedged item in a fair value hedging relationship, the carrying amount in the consolidated balance sheet includes changes in fair value attributable to the hedged risk(s).


(b)	For business combinations completed prior to application of IFRS 3, contingent consideration is recognized when payment becomes probable. See Note B.3.1.




F-22	SANOFI / FORM 20-F 2019

NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS – (Continued)

The fair value of the Dexcom equity derivatives (see Note D.20.c) is classified as Level 2 because the valuation is based on a generally accepted technique (the Black & Scholes model) that uses inputs from directly observable market parameters (share price, risk free rate and implied volatility).

B.8.6. Derecognition of financial instruments

Financial assets are derecognized when the contractual rights to cash flows from the asset have ended or have been transferred and when Sanofi has transferred substantially all the risks and rewards of ownership of the asset. If Sanofi has neither transferred nor retained substantially all the risks and rewards of ownership of a financial asset, it is derecognized if Sanofi does not retain control of the asset.

A financial liability is derecognized when Sanofi’s contractual obligations in respect of the liability are discharged, cancelled or extinguished.

B.8.7. Risks relating to financial instruments

Market risks in respect of non-current financial assets, cash equivalents, derivative instruments and debt are described in the discussions of risk factors presented in Item 3.D. and Item 11 of Sanofi’s Annual Report on Form 20-F for 2019 .

Credit risk is the risk that customers may fail to pay their debts. For a description of credit risk, refer to "We are subject to the risk of non-payment by our customers" within Item 3.D. and Item 11 of Sanofi’s Annual Report on Form 20-F for 2019 .

B.9. Inventories

Inventories are measured at the lower of cost or net realizable value. Cost is calculated using the weighted average cost method or the first-in, first-out method, depending on the nature of the inventory.

The cost of finished goods inventories includes costs of purchase, costs of conversion and other costs incurred in bringing the inventories to their present location and condition.

Net realizable value is the estimated selling price in the ordinary course of business less the estimated costs of completion and the estimated costs necessary to make the sale.

During the launch phase of a new product, any inventories of that product are written down to zero pending regulatory approval. The write-down is reversed once it becomes highly probable that marketing approval will be obtained.

B.10. Cash and cash equivalents

Cash and cash equivalents as shown in the consolidated balance sheet and statement of cash flows comprise cash, plus liquid short-term investments that are readily convertible into cash and are subject to an insignificant risk of changes in value in the event of movements in interest rates.

B.11. Treasury shares

In accordance with IAS 32, Sanofi treasury shares are deducted from equity, irrespective of the purpose for which they are held. No gain or loss is recognized in the income statement on the purchase, sale, impairment or cancellation of treasury shares.

B.12. Provisions for risks

In accordance with IAS 37 (Provisions, Contingent Liabilities and Contingent Assets), Sanofi records a provision when it has a present obligation, whether legal or constructive, as a result of a past event; it is probable that an outflow of resources embodying economic benefits will be required to settle the obligation; and a reliable estimate can be made of the amount of the outflow of resources.

If the obligation is expected to be settled more than twelve months after the end of the reporting period, or has no definite settlement date, the provision is recorded within Non-current provisions and other non-current liabilities.

Provisions relating to the insurance programs in which Sanofi’s captive insurance company participates are based on risk exposure estimates calculated by management, with assistance from independent actuaries, using IBNR (Incurred But Not Reported) techniques. Those techniques use past claims experience, within Sanofi and in the market, to estimate future trends in the cost of claims.

Contingent liabilities are not recognized, but are disclosed in the notes to the financial statements unless the possibility of an outflow of economic resources is remote.

Sanofi estimates provisions on the basis of events and circumstances related to present obligations at the end of the reporting period and of past experience, and to the best of management’s knowledge at the date of preparation of the financial statements.

Reimbursements offsetting the probable outflow of resources are recognized as assets only if it is virtually certain that they will be received. Contingent assets are not recognized.

Restructuring provisions are recognized if Sanofi has a detailed, formal restructuring plan at the end of the reporting period and has announced its intention to implement this plan to those affected by it.

No provisions are recorded for future operating losses.

Sanofi records non-current provisions for certain obligations, such as legal or constructive environmental obligations and litigation, where an outflow of resources is probable and the amount of the outflow can be reliably estimated. Where the effect of the time value of money is material, those provisions are measured at the present value of the expenditures expected to be required to settle the obligation, calculated using a discount rate that reflects an estimate of the time value of money and the risks specific to the obligation.

Increases in provisions to reflect the effects of the passage of time are recognized within Financial expenses .

NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS – (Continued)

B.13. Revenue recognition

B.13.1. Net sales

Revenue arising from the sale of goods is presented in the income statement within Net sales . Net sales comprise revenue from sales of pharmaceutical products, consumer healthcare products, active ingredients and vaccines, net of sales returns, of customer incentives and discounts, and of certain sales-based payments paid or payable to the healthcare authorities. Analyses of net sales are provided in Note D.35.1. “Segment Information”.

In accordance with IFRS 15 (Revenue from Contracts with Customers), such revenue is recognized when Sanofi transfers control over the product to the customer; control of an asset refers to the ability to direct the use of, and obtain substantially all of the remaining benefits from, that asset. For the vast majority of contracts, revenue is recognized when the product is physically transferred, in accordance with the delivery and acceptance terms agreed with the customer.

For contracts entered into by Sanofi Pasteur, transfer of control is usually determined by reference to the terms of release (immediate or deferred) and acceptance of batches of vaccine.

In the case of contracts with distributors, Sanofi does not recognize revenue when the product is physically transferred to the distributor if the products are sold on consignment, or if the distributor acts as agent. In such cases, revenue is recognized when control is transferred to the end customer, and the distributor’s commission is presented within the line item Selling and general expenses in the income statement.

The amount of revenue recognized reflects the various types of price reductions or rights of return offered by Sanofi to its customers on certain products. Such price reductions and rights of return qualify as variable consideration under IFRS 15.

In particular, products sold in the United States are covered by various Government and State programs (such as Medicare and Medicaid) under which products are sold at a discount. Rebates are granted to healthcare authorities, and under contractual arrangements with certain customers. Some wholesalers are entitled to chargeback incentives based on the selling price to the end customer, under specific contractual arrangements. Cash discounts may also be granted for prompt payment. Returns, discounts, incentives and rebates, as described above, are recognized in the period in which the underlying sales are recognized as a reduction of gross sales.

These amounts are calculated as follows:


▪	The amount of chargeback incentives is estimated on the basis of the relevant subsidiary’s standard sales terms and conditions, and in certain cases on the basis of specific contractual arrangements with the customer.


▪	The amount of rebates based on attainment of sales targets is estimated and accrued as each of the underlying sales transactions is recognized.


▪	The amount of price reductions under Government and State programs, largely in the United States, is estimated on the basis of the specific terms of the relevant regulations or agreements, and accrued as each of the underlying sales transactions is recognized.

▪

The amount of sales returns is calculated on the basis of management’s best estimate of the amount of product that will ultimately be returned by custome rs. In countries where product returns are possible, Sanofi operates a returns policy that allows the customer to return products within a certain period either side of the expiry date (usually 12 months after the expiry date). The amount recognized for returns is estimated on the basis of past experience of sales returns. Sanofi also takes into account factors such as levels of inventory in its various distribution channels, product expiry dates, information about potential discontinuation of products, the entry of competing generics into the market, and the launch of over-the-counter medicines. Most product return clauses relate solely to date-expired products, which cannot be resold and are destroyed. Sanofi does not recognize a right of return asset in the balance sheet for contracts that allow for the return of time-expired products, since those products have no value.

The estimated amounts described above are recognized in the income statement within Net sales as a reduction of gross sales, and within Other current liabilities in the balance sheet. They are subject to regular review and adjustment as appropriate based on the most recent data available to management. Sanofi believes that it has the ability to measure each of the above amounts reliably, using the following factors in developing its estimates:


▪	the na ture and patient profile of the underlying product;


▪	the applicable regulations or the specific terms and conditions of contracts with governmental authorities, wholesalers and other customers;


▪	historical data relating to similar contracts, in the case of qualitative and quantitative rebates and chargeback incentives;


▪	past experience and sales growth trends for the same or similar products;


▪	actual inventory levels in distribution channels, monitored by Sanofi using internal sales data and externally provided data;


▪	the shelf life of Sanofi products; and


▪	market trends inc luding competition, pricing and demand.

An analysis of provisions for discounts, rebates and sales returns is provided in Note D.23.

B.13.2. Other revenues

Other revenues mainly comprise royalties received from licensing intellectual property rights to third parties, and VaxServe sales of products sourced from third-party manufacturers.

Royalties received under licensing arrangements are recognized over the period during which the underlying sales are recognized.




F-24	SANOFI / FORM 20-F 2019

NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS – (Continued)

VaxServe is a Vaccines segment entity whose operations include the distribution within the United States of vaccines and other products manufactured by third parties. VaxServe sales of products sourced from third-party manufacturers are presented within Other revenues .

B.14. Cost of sales

Cost of sales consists primarily of the industrial cost of goods sold, payments made under licensing agreements, and distribution costs. The industrial cost of goods sold includes the cost of materials, depreciation of property, plant and equipment, amortization of software, personnel costs, and other expenses attributable to production.

B.15. Research and development

Note B.4.1. “Research and development not acquired in a business combination” and Note B.4.3. “Other intangible assets acquired in a business combination” describe the principles applied to the recognition of research and development costs.

Contributions or reimbursements received from alliance partners are recorded as a reduction of Research and development expenses .

B.16. Other operating income and expenses

B.16.1. Other operating income

Other operating income includes the share of profits that Sanofi is entitled to receive from alliance partners in respect of product marketing agreements. It also includes revenues generated under certain complex agreements, which may include partnership and co-promotion arrangements.

Upfront payments received are deferred until the service obligation is met. Milestone payments are assessed on a case by case basis, and recognized in the income statement on delivery of the products and/or upon the service obligation being met. Revenue generated in connection with these services is recognized on the basis of delivery of the goods or provision of the services to the other contracting party.

This line item also includes realized and unrealized foreign exchange gains and losses on operating activities (see Note B.8.3.), and operating gains on disposals not regarded as major disposals (see Note B.20.).

B.16.2. Other operating expenses

Other operating expenses mainly comprise the share of profits that alliance partners are entitled to receive from Sanofi under product marketing agreements.

B.17. Amortization and impairment of intangible assets

B.17.1. Amortization of intangible assets

The expenses recorded in this line item comprise amortization of product rights and other intangible assets (see Note D.4.), given that the benefit of those rights to Sanofi’s commercial, industrial and development functions cannot be separately identified.

Amortization of software, and of other rights of an industrial or operational nature, is recognized as an expense in the income statement, in the relevant line items of expense by function.

B.17.2. Impairment of intangible assets

This line item records impairment losses (other than those associated with restructuring) recognized against intangible assets (including goodwill, but excluding software and other rights of an industrial or operational nature), and any reversals of such impairment losses.

B.18. Fair value remeasurement of contingent consideration

Changes in the fair value of contingent consideration that was (i) already carried in the books of an acquired entity, or (ii) granted in connection with a business combination and initially recognized as a liability in accordance with IFRS 3, are reported in profit or loss. Such adjustments are reported separately in the income statement, in the line item Fair value remeasurement of contingent consideration.

This line item also includes changes in the fair value of contingent consideration receivable in connection with a divestment and classified as a financial asset at fair value through profit or loss.

Finally, it includes the effect of the unwinding of discount, and of exchange rate movements where the asset or liability is expressed in a currency other than the functional currency of the reporting entity.

B.19. Restructuring costs and similar items

Restructuring costs are expenses incurred in connection with the transformation or reorganization of Sanofi’s operations or support functions. Such costs include collective redundancy plans, compensation to third parties for early termination of contracts, and commitments made in connection with transformation or reorganization decisions. They also include accelerated depreciation charges arising from site closures and losses on asset disposals resulting from such decisions.

In addition, this line item includes expenses incurred in connection with programs implemented as part of the transformation strategy announced in November 2015 intended to deliver a global information systems solution, to standardize and consolidate processes, and to transition towards a worldwide services platform.




SANOFI / FORM 20-F 2019	F-25

NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS – (Continued)

B.20. Other gains and losses, and litigation

The line item Other gains and losses, and litigation includes the impact of material transactions of an unusual nature or amount which Sanofi believes it necessary to report separately in the income statement in order to improve the relevance of the financial statements, such as:


▪	ga ins and losses on major disposals of property, plant and equipment, of intangible assets, of assets (or groups of assets and liabilities) held for sale, or of a business within the meaning of IFRS 3, other than those considered to be restructuring costs;


▪	impairment losses and reversals of impairment losses on assets (or groups of assets and liabilities) held for sale, other than those considered to be restructuring costs;


▪	gains on bargain purchases;


▪	costs and provisions relating to major litigation; and


▪	pre-tax separation cost s associated with the process of disinvesting from operations in the event of a major divestment.

B.21. Financial expenses and income

B.21.1. Financial expenses

Financial expenses mainly comprise interest charges on debt financing; negative changes in the fair value of financial instruments (where changes in fair value are recognized in profit or loss); realized and unrealized foreign exchange losses on financing and investing activities; impairment losses on financial instruments; and any reversals of impairment losses on financial instruments.

Financial expenses also include expenses arising from the unwinding of discount on long-term provisions, and the net interest cost related to employee benefits. This line item does not include commercial cash discounts, which are deducted from net sales.

B.21.2. Financial income

Financial income includes interest and dividend income; positive changes in the fair value of financial instruments (where changes in fair value are recognized in profit or loss); realized and unrealized foreign exchange gains on financing and investing activities; and gains on disposals of financial assets at fair value through profit or loss.

B.22. Income tax expense

Income tax expense includes all current and deferred taxes of consolidated companies.

Sanofi accounts for deferred taxes in accordance with IAS 12 (Income Taxes), using the methods described below:


▪	Deferred tax assets and liabilities are recognized on taxable and deductible temporary differences, and on tax loss carry-forwards. Temporary differences are differences between the carrying amount of an asset or liability in the balance sheet and its tax base.

▪

French business taxes include a value added based component: “CVAE” ( Cotisation sur la Valeur Ajoutée des Entreprises ). Given that CVAE is (i) calculated as the amount by which certain revenues exceed certain expenses and (ii) borne primarily by companies that own intellectual property rights on income derived from those rights (royalties, and margin on sales to third parties and to Sanofi entities), it is regarded as meeting the definition of income taxes specified in IAS 12, paragraph 2 (“taxes which are based on taxable profits”).


▪	Deferred tax assets and liabilities are calculated using the tax rate expected to apply in the period when the corresponding temporary differences are expected to reverse, based on tax rates enacted or substantively enacted at the end of the reporting period.


▪	Deferred tax assets are recognized in respect of deductible temporary differences, tax losses available for carry-forward and unused tax credits to the extent that future recovery is regarded as probable. The recoverability of deferred tax assets is assessed on a case-by-case basis, taking into account the profit forecasts contained in Sanofi’s medium-term business plan.

▪

A deferred tax liability is recognized for temporary differences relating to interests in subsidiaries, associates and joint ventures, except in cases where Sanofi is able to control the timing of the reversal of the temporary differences. This applies in particular when Sanofi is able to control dividend policy and it is probable that the temporary differences will not reverse in the foreseeable future.


▪	No deferred tax is recognized on eliminations of intragroup transfers of interests in subsidiaries, associates or joint ventures.

▪

Each tax entity calculates its own net deferred tax position. All net deferred tax asset and liability positions are then aggregated and shown in separate line items on the relevant side of the consolidated balance sheet. Deferred tax assets and liabilities are offset only if (i) Sanofi has a legally enforceable right to offset current tax assets and current tax liabilities, and (ii) the deferred tax assets and deferred tax liabilities relate to income taxes levied by the same taxation authority.


▪	Deferred taxes are not discounted, except implicitly in the case of deferred taxes on assets and liabilities which are already impacted by discounting.


▪	Withholding taxes on intragro up royalties and dividends, and on royalties and dividends collected from third parties, are accounted for as current income taxes.

In accounting for business combinations, Sanofi complies with IFRS 3 as regards the recognition of deferred tax assets after the initial accounting period. Consequently, any deferred tax assets recognized by the acquiree after the end of this period in respect of temporary differences or tax loss carry-forwards existing at the acquisition date are recognized in profit or loss.




F-26	SANOFI / FORM 20-F 2019

NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS – (Continued)

The positions adopted by Sanofi in tax matters are based on its interpretation of tax laws and regulations. Some of those positions may be subject to uncertainty. In such cases, Sanofi assesses the amount of the tax liability on the basis of the following assumptions: that its position will be examined by one or more tax authorities on the basis of all relevant information; that a technical assessment is carried out with reference to legislation, case law, regulations, and established practice; and that each position is assessed individually (or collectively where appropriate), with no offset or aggregation between positions. Those assumptions are assessed on the basis of facts and circumstances existing at the end of the reporting period. When an uncertain tax liability is regarded as probable, it is measured on the basis of Sanofi’s best estimate and recognized as a liability; uncertain tax assets are not recognized. The amount of the liability includes any penalties and late payment interest. The line item Income tax expense includes the effects of tax reassessments and tax disputes, and any penalties and late payment interest arising from such disputes that have the characteristics of income taxes within the meaning of paragraph 2 of IAS 12 (“taxes which are based on taxable profits”). Tax exposures relating to corporate income taxes are presented separately within Other non-current liabilities (see Note D.19.4).

No deferred taxation is recognized on temporary differences that are liable to be subject to US global intangible low taxed income (GILTI) provisions. The related tax expense is recognized in the year in which it is declared in the tax return to the extent that it arises from the existence of non-US profits that exceed the theoretical return on investment specified in the GILTI provisions and are taxed at a rate lower than the applicable US tax rate.

B.23. Employee benefit obligations

Sanofi offers retirement benefits to employees and retirees. Such benefits are accounted for in accordance with IAS 19 (Employee Benefits).

Benefits are provided in the form of either defined contribution plans or defined benefit plans. In the case of defined contribution plans, the cost is recognized immediately in the period in which it is incurred, and equates to the amount of the contributions paid by Sanofi. For defined benefit plans, Sanofi generally recognizes its obligations to pay pensions and similar benefits to employees as a liability, based on an actuarial estimate of the rights vested or currently vesting in employees and retirees, using the projected unit credit method. Estimates are performed at least once a year, and rely on financial assumptions (such as discount rates) and demographic assumptions (such as life expectancy, retirement age, employee turnover, and the rate of salary increases).

Obligations relating to other post-employment benefits (healthcare and life insurance) offered by Sanofi companies to employees are also recognized as a liability based on an actuarial estimate of the rights vested or currently vesting in employees and retirees at the end of the reporting period.

Such liabilities are recognized net of the fair value of plan assets.

In the case of multi-employer defined benefit plans where plan assets cannot be allocated to each participating employer with sufficient reliability, the plan is accounted for as a defined contribution plan, in accordance with paragraph 34 of IAS 19.

The benefit cost for the period consists primarily of current service cost, past service cost, net interest cost, gains or losses arising from plan settlements not specified in the terms of the plan, and actuarial gains or losses arising from plan curtailments. Net interest cost for the period is determined by applying the discount rate specified in IAS 19 to the net liability (i.e. the amount of the obligation, net of plan assets) recognized in respect of defined benefit plans. Past service cost is recognized immediately in profit or loss in the period in which it is incurred, regardless of whether or not the rights have vested at the time of adoption (in the case of a new plan) or of amendment (in the case of an existing plan).

Actuarial gains and losses on defined benefit plans (pensions and other post-employment benefits), also referred to as "Remeasurements of the net defined benefit liability (asset)" , arise as a result of changes in financial and demographic assumptions, experience adjustments, and the difference between the actual return and interest cost on plan assets. The impacts of those remeasurements are recognized in Other comprehensive income , net of deferred taxes; they are not subsequently reclassifiable to profit or loss.

B.24. Share-based payment

Share-based payment expense is recognized as a component of operating income, in the relevant classification of expense by function. In measuring the expense, the level of attainment of any performance conditions is taken into account.

B.24.1. Stock option plans

Sanofi has granted a number of equity-settled share-based payment plans (stock option plans) to some of its employees. The terms of those plans may make the award contingent on the attainment of performance criteria for some of the grantees.

In accordance with IFRS 2 (Share-Based Payment), services received from employees as consideration for stock options are recognized as an expense in the income statement, with the opposite entry recognized in equity. The expense corresponds to the fair value of the stock option plans, and is charged to income on a straight-line basis over the four -year vesting period of the plan.

The fair value of stock option plans is measured at the date of grant using the Black-Scholes valuation model, taking into account the expected life of the options. The resulting expense also takes into account the expected cancellation rate of the options. The expense is adjusted over the vesting period to reflect actual cancellation rates resulting from option-holders ceasing to be employed by Sanofi.

B.24.2. Employee share ownership plans

Sanofi may offer its employees the opportunity to subscribe to reserved share issues at a discount to the reference market price. Shares awarded to employees under such plans fall within the scope of IFRS 2. Consequently, an expense is recognized at the subscription date, based on the value of the discount offered to employees.

B.24.3. Restricted share plans

Sanofi may award restricted share plans to certain of its employees. The terms of those plans may make the award contingent on the attainment of performance criteria for some of the grantees.




SANOFI / FORM 20-F 2019	F-27

NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS – (Continued)

In accordance with IFRS 2, an expense equivalent to the fair value of such plans is recognized on a straight line basis over the vesting period of the plan, with the opposite entry recognized in equity. Depending on the country, the vesting period of such plans is either three or four years . Plans with a two -year or three -year vesting period are subject to a two -year lock-up period.

The fair value of stock option plans is based on the fair value of the equity instruments granted, representing the fair value of the services received during the vesting period. The fair value of an equity instrument granted under a plan is the market price of the share at the grant date, adjusted for expected dividends during the vesting period.

B.25. Earnings per share

Basic earnings per share is calculated using the weighted average number of shares outstanding during the reporting period, adjusted on a time-weighted basis from the acquisition date to reflect the number of own shares held by Sanofi. Diluted earnings per share is calculated on the basis of the weighted average number of ordinary shares, computed using the treasury stock method.

This method assumes that (i) all outstanding dilutive options and warrants are exercised, and (ii) Sanofi acquires its own shares at the quoted market price for an amount equivalent to the cash received as consideration for the exercise of the options or warrants, plus the expense arising on unamortized stock options.

B.26. Segment information

In accordance with IFRS 8 (Operating Segments), the segment information reported by Sanofi is prepared on the basis of internal management data provided to the Chief Executive Officer, who is the chief operating decision maker. The performance of those segments is monitored individually using internal reports and common indicators. Disclosures about operating segments required under IFRS 8 are presented in Note D.35. “Segment information” to the consolidated financial statements.

Since December 31, 2017, Sanofi has had three operating segments: Pharmaceuticals, Consumer Healthcare and Human Vaccines (Vaccines).

The Pharmaceuticals segment comprises the commercial operations of the following global franchises: Specialty Care (Rare Diseases, Multiple Sclerosis, Oncology, Immunology and Rare Blood Disorders) and Primary Care (Diabetes, Cardiovascular and Established Prescription Products), together with research, development and production activities dedicated to the Pharmaceuticals segment. This segment also includes associates whose activities are related to pharmaceuticals, in particular Sanofi's share of Regeneron.

The Vaccines segment comprises, for all geographical territories (including certain European territories previously included in the Sanofi Pasteur MSD joint venture), the commercial operations of Sanofi Pasteur, together with research, development and production activities dedicated to vaccines.

Inter-segment transactions are not material.

The costs of Sanofi’s global functions (Medical Affairs, External Affairs, Finance, Human Resources, Legal Affairs, Information Solutions & Technologies, Sanofi Business Services, etc.) are managed centrally at group-wide level, and are presented within the “Other” category. That category also includes other reconciling items such as retained commitments in respect of divested activities.

Information about operating segments for the years ended December 31, 2019 , 2018 and 2017 is presented in Note D.35. “Segment information”.

B.27. Management of capital

In order to maintain or adjust the capital structure, Sanofi can adjust the amount of dividends paid to shareholders, repurchase its own shares, issue new shares, or issue securities giving access to its capital.

The following objectives are defined under the terms of Sanofi’s share repurchase programs:


▪	the implementation of a ny stock option plan giving entitlement to purchase shares in the Sanofi parent company;


▪	the allotment or sale of shares to employees under statutory profit sharing schemes and employee savings plans;


▪	the consideration-free allotment of shares (i.e. restricted share plans);


▪	the cancellation of some or all of the repurchased shares;


▪	market- making in the secondary market by an investment services provider under a liquidity contract in compliance with the ethical code recognized by the Autorité des marchés financiers (AMF);


▪	the de livery of shares on the exercise of rights attached to securities giving access to the capital by redemption, conversion, exchange, presentation of a warrant or any other means;


▪	the delivery of shares (in exchange, as payment, or otherwise) in connection with mergers and acquisitions;


▪	the execution by an investment services provider of purchases, sales or transfers by any means, in particular via off-market trading; or


▪	any other pur pose that is or may in the future be authorized under the applicable laws and regulations.

Sanofi is not subject to any constraints on equity capital imposed by third parties.

NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS – (Continued)

Total equity includes Equity attributable to equity holders of Sanofi and Equity attributable to non-controlling interests , as shown in the consolidated balance sheet.

Sanofi defines “Net debt” as (i) the sum of short-term debt, long-term debt and interest rate derivatives and currency derivatives used to hedge debt, minus (ii) the sum of cash and cash equivalents and interest rate derivatives and currency derivatives used to hedge cash and cash equivalents.

C/ Principal alliances

C.1. Alliance arrangements with Regeneron Pharmaceuticals, Inc. (Regeneron)

Collaboration agreements on human therapeutic antibodies

Discovery and development

Under the 2009 amended agreements, Sanofi funded the discovery and pre-clinical development of fully human therapeutic antibodies up to a maximum of $ 160 million per year through 2017. Because Sanofi decided not to exercise its option to extend the Discovery and Preclinical Development Agreement, that agreement expired on December 31, 2017.

Upon Sanofi ’s exercise of an option on an antibody under the Discovery and Preclinical Development Agreement, the antibody became a Licensed Product under the License and Collaboration Agreement, pursuant to which Sanofi and Regeneron co- develop the antibody with Sanofi initially being wholly responsible for funding the development program . On receipt of the first positive Phase III trial results for any antibody being developed under the License and Collaboration Agreement , the subsequent Phase III costs for that antibody are split 80 % Sanofi, 20 % Regeneron. Amounts received from Regeneron under those arrangements are recognized by Sanofi as a reduction in the line item Research and development expenses . Co-development with Regeneron of the antibodies Praluent ^® , Dupixent ^® , Kevzara ^® and REGN3500 (SAR440340) is ongoing under the License and Collaboration Agreement at this time .

Once a product begins to be commercialized, and provided that the share of quarterly results under the agreement represents a profit, Sanofi is entitled to an additional portion of Regeneron’s profit-share (capped at 10 % of Regeneron’s share of quarterly profits) until Regeneron has paid 50 % of the cumulative development costs incurred by the parties in the collaboration (see footnote g(ii) to the table provided in Note D.21.1, "Off balance sheet commitments relating to operating activities").

Commercialization

Sanofi recognizes all sales of the antibodies. Sanofi and Regeneron share co-promotion rights on sales of the co-developed antibodies. Profits and losses arising from commercial operations in the United States are split 50 /50. Outside the United States, Sanofi is entitled to between 55 % and 65 % of profits depending on sales of the antibodies, and bears 55 % of any losses. The share of profits and losses due to or from Regeneron under the agreement is recognized within the line items Other operating income or Other operating expenses , which are components of operating income. In addition, Regeneron is entitled to receive payments of up to $ 250 million contingent on the attainment of specified levels of aggregate sales on all antibodies outside the United States.

Amendments to the collaboration agreements

Immuno-oncology (IO) collaboration agreements

The two companies agreed to invest approximately $ 1 billion from discovery through proof of concept (POC) development (usually a Phase IIa study) of monotherapy and novel combinations of immuno-oncology antibody candidates to be funded 25 % by Regeneron ( $ 250 million ) and 75 % by Sanofi ( $ 750 million ). The two companies also agreed to reallocate $ 75 million (spread over three years ) to immuno-oncology antibody research and development from Sanofi’s $ 160 million annual contribution to their existing antibody discovery collaboration.




SANOFI / FORM 20-F 2019	F-29

NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS – (Continued)

payment of $ 462 million to Regeneron as consideration for (i) the termination of the 2015 IO Discovery Agreement, (ii) the prepayment for certain IO Development Activities regarding the BCMAxCD3 Program and the MUC16xCD3 Program, and (iii) the reimbursement of costs incurred by Regeneron under the 2015 IO Discovery Agreement during the fourth quarter of 2018. This gives Sanofi increased flexibility to advance its early-stage immuno-oncology pipeline independently, while Regeneron retains all rights to its other immuno-oncology discovery and development programs.

The ongoing development and commercialization collaboration on Libtayo ^® (cemiplimab) is unaffected by the amendments to the IO Discovery and Development Agreement.

Upon establishment of POC, or when the allocated funding has been expended, whichever is earlier, Sanofi can exercise its opt-in rights to further develop and commercialize under the IO LCA the two candidates derived from the amended IO Discovery Agreement. If Sanofi exercises its opt-in rights with respect to the BCMAxCD3program, Sanofi will lead the development and global commercialization of BCMAxCD3 candidate antibody and fund the development costs in full; Regeneron will refund 50 % of those costs provided that the share of quarterly results under the IO LCA represents a profit, subject to a cap set at 10 % of Regeneron’s profit-share. If Sanofi exercises its opt-in rights with respect to the MUC16xCD3 program, Regeneron will lead development worldwide and commercialization in the United States; development costs and global profits, will be shared 50 /50 between Sanofi and Regeneron.

Libtayo ^® (cemiplimab)

Under the 2015 IO LCA as amended in January 2018, Sanofi and Regeneron committed funding of no more than $ 1,640 million , split on a 50 /50 basis ( $ 820 million per company), for the development of REGN2810 (cemiplimab, trademark Libtayo ^® ), a PD-1 inhibitor antibody. Regeneron is responsible for the commercialization of Libtayo ^® in the United States, and Sanofi in all other territories.

The IO LCA also provided for a one-time milestone payment of $ 375 million by Sanofi to Regeneron in the event that sales of a PD-1 product and any other collaboration antibody sold for use in combination with a PD-1 product were to exceed, in the aggregate, $ 2 billion in any consecutive 12-month period.

Under the IO License and Commercialization Agreement (IO LCA) Sanofi and Regeneron share equally in profits and losses in connection with the commercialization of collaboration products , except that Sanofi is entitled to an additional share of profits capped at 10 % of the share of Regeneron’s quarterly profits to reimburse Sanofi of up to 50 % of the clinical development costs funded by Sanofi under the IO Discovery Agreement, as amended.

Investor agreement

In January 2014, Sanofi and Regeneron amended the investor agreement that has existed between the two companies since 2007. Under the terms of the amendment, Sanofi accepted various restrictions. Sanofi is bound by certain “standstill” provisions, which contractually prohibit Sanofi from seeking to directly or indirectly exert control of Regeneron or acquiring more than 30 % of Regeneron’s capital stock (consisting of the outstanding shares of common stock and the shares of Class A stock). This prohibition will remain in place until the earlier of (i) the later of the fifth anniversaries of the expiration or earlier termination of the Zaltrap ^® collaboration agreement with Regeneron (related to the development and commercialization of Zaltrap ^® ) or the collaboration agreement with Regeneron on monoclonal antibodies (see “Collaboration agreements on human therapeutic antibodies” above), each as amended and (ii) other specified events.

Sanofi also agreed to vote as recommended by Regeneron’s Board of Directors, except that it may elect to vote proportionally with the votes cast by all of Regeneron’s other shareholders with respect to certain change-of-control transactions, and to vote in its sole discretion with respect to liquidation or dissolution, stock issuances equal to or exceeding 20 % of the outstanding shares or voting rights of Regeneron’s Class A Stock and Common Stock (taken together), and new equity compensation plans or amendments if not materially consistent with Regeneron’s historical equity compensation practices. As soon as it had passed the threshold of 20 % ownership of the capital stock, Sanofi exercised its right to designate an independent director, who was appointed to the Board of Directors of Regeneron. The interest held by Sanofi in Regeneron has been consolidated by the equity method since April 2014. On the conditions set out in the Amended Investor Agreement of January 2014, Sanofi’s right to designate a Regeneron board member was contingent on Sanofi maintaining its percentage share of Regeneron’s outstanding capital stock (measured on a quarterly basis) at a level no lower than the highest percentage level previously achieved, with the maximum requirement capped at 25 % . In addition, Sanofi’s interest in Regeneron was subject to a lock-up clause. Those restrictions were amended by the letter agreement of January 2018 (see below).




F-30	SANOFI / FORM 20-F 2019

NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS – (Continued)

Pursuant to the 2018 Letter Agreement, Regeneron agreed to grant a limited waiver of the lock-up clause and the obligation to maintain the “Highest Percentage Threshold” in the Amended and Restated Investor Agreement between the companies, so that Sanofi may elect to sell a small percentage of the Regeneron common stock it owns to fund a portion of the cemiplimab and dupilumab development expansion. This waiver will allow Sanofi to sell up to an aggregate of 1.4 million shares of Regeneron common stock to Regeneron in private transactions through the end of 2020. If Regeneron decides not to purchase the shares, Sanofi will be allowed to sell those shares on the open market, subject to certain volume and timing limitations. Upon expiration of the limited waiver under the 2018 Letter Agreement, the Amended and Restated Investor Agreement will be amended to define “Highest Percentage Threshold” as the lower of (i) 25 % of Regeneron outstanding shares of Class A Stock and Common Stock (taken together) and (ii) the higher of (a) Sanofi’s percentage ownership of Class A Stock and Common Stock (taken together) on such termination date and (b) the highest percentage ownership of Regeneron outstanding shares of Class A Stock and Common Stock (taken together) Sanofi attains following such termination date.

As of December 31, 2019 , Sanofi had sold 530,172 shares of Regeneron stock to Regeneron out of the 1.4 million shares covered by the 2018 Letter Agreement.

C.2. Alliance arrangements with Bristol-Myers Squibb (BMS)

On September 27, 2012, Sanofi and BMS signed an agreement relating to their alliance following the loss of exclusivity of Plavix ^® and Avapro ^® /Avalide ^® in many major markets.

Under the terms of this agreement, effective January 1, 2013, BMS returned to Sanofi its rights to Plavix ^® and Avapro ^® /Avalide ^® in all markets worldwide with the exception of Plavix ^® in the United States and Puerto Rico, giving Sanofi sole control and freedom to operate commercially in respect of those products. In exchange, BMS received royalty payments on Sanofi’s sales of branded and unbranded Plavix ^® and Avapro ^® /Avalide ^® worldwide (except for Plavix ^® in the United States and Puerto Rico) until 2018, and also received a payment of $ 200 million from Sanofi in December 2018, part of which is for buying out the non-controlling interests (see Note D.18.). Rights to Plavix ^® in the United States and Puerto Rico remain unchanged and continued to be governed by the terms of the original agreement until March 2020.

D.5. Impairment of intangible assets and property, plant and equipment

Goodwill

The recoverable amount of cash generating units (CGUs) is determined by reference to the value in use of each CGU, based on discounted estimates of the future cash flows from the CGU, in accordance with the policies described in Note B.6.1.

Goodwill is monitored internally at the level of each of the three current CGUs (Pharmaceuticals, Consumer Healthcare and Vaccines). Each of those CGUs reflects on a global scale all the key organizational components involved in commercial, R&D and industrial decision-making for that CGU. Sanofi believes those decisions have a significant influence on the generation of cash flows for each CGU.

The allocation of goodwill as of December 31, 2019 is shown below:



(€ million)	Pharmaceuticals	Consumer Healthcare	Vaccines	Total
Goodwill	36,565	6,594	1,360	44,519

The value in use of each CGU was determined by applying an after-tax discount rate to estimated future after-tax cash flows.

A separate discount rate is used for each CGU to reflect the specific economic conditions of the CGU.

The rates used for impairment testing in 2019 were 7.25 % for the Pharmaceuticals CGU (versus 7.75 % in 2018), 7.00 % for the Consumer Healthcare CGU and 7.25 % for the Vaccines CGU (both unchanged from 2018); an identical value in use for Sanofi as a whole would be obtained by applying a uniform 7.2 % rate to all three CGUs (versus 7.5 % in 2018).

The pre-tax discount rates applied to estimated pre-tax cash flows are calculated by iteration from the previously-determined value in use. Those pre-tax discount rates were 9.7 % for the Pharmaceuticals CGU, 8.9 % for the Consumer Healthcare CGU and 9.4 % for the Vaccines CGU, and equate to a uniform rate of 9.6 % for Sanofi as a whole.

The assumptions used in testing goodwill for impairment are reviewed annually. Apart from the discount rate, the principal assumptions used in 2019 were as follows:


▪	The p erpetual growth rates applied to future cash flows were zero for the Pharmaceuticals CGU, 2 % for the Consumer Healthcare CGU, and 0.5 % for the Vaccines CGU.


▪	Sanofi also applies assumptions on the probability of success of current research and development projects, and more generally on its ability to renew the pro duct portfolio in the longer term.

Value in use (determined as described above) is compared with the carrying amount, and this comparison is then subjected to sensitivity analyses by reference to the principal parameters, including:


▪	change s in the discount rate;


▪	changes in the perpetual growth rate;


▪	fluctuations in o perating margin.

No impairment of goodwill would need to be recognized in the event of a reasonably possible change in the assumptions used in 2019 .

A value in use calculation for each of the CGUs would not result in an impairment loss using:


▪	a discou nt rate up to 2.3 percentage points above the rates actually used; or


▪	a perpetual growth rate up to 5.3 percentage points below the rates actually used; or


▪	an operating margi n up to 6.6 percentage points below the rates actually used.

No impairment losses were recognized against goodwill in the years ended December 31, 2019 , 2018 or 2017 .




SANOFI / FORM 20-F 2019	F-41

NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS – (Continued)

Other intangible assets

When there is evidence that an asset may have become impaired, the asset’s value in use is calculated by applying an after-tax discount rate to the estimated future after-tax cash flows from that asset. For the purposes of impairment testing, the tax cash flows relating to the asset are determined using a notional tax rate incorporating the notional tax benefit that would result from amortizing the asset if its value in use were regarded as its depreciable amount for tax purposes. Applying after-tax discount rates to after-tax cash flows gives the same values in use as would be obtained by applying pre-tax discount rates to pre-tax cash flows.

The after-tax discount rates used in 2019 for impairment testing of other intangible assets in the Pharmaceuticals, Consumer Healthcare and Vaccines CGUs were obtained by adjusting Sanofi’s weighted average cost of capital to reflect specific country and business risks, giving after-tax discount rates in a range from 7.25 % to 9.75 % .

In most instances, there are no market data that would enable fair value less costs to sell to be determined other than by means of developing a similar estimate based on future cash flows. Consequently, recoverable amount is in substance equal to value in use. The estimates used to determine value in use are sensitive to the assumptions specific to the nature of the asset and of Sanofi's activities. Apart from the discount rate, the principal assumptions used in 2019 were as follows:


▪	mid and long-term sales forecasts,


▪	perpetual growth or attrition rates, when applicable, and


▪	probability of s uccess of current research and development projects.

The assumptions used in testing intangible assets for impairment are, at least, reviewed annually.

In 2019 , 2018 and 2017 , impairment testing of other intangible assets (excluding software) resulted in the recognition of net impairment losses as shown below:



(€ million)	2019	2018	2017
Impairment of other intangible assets (excluding software)	3,604	720	310

Research and development projects ^(d)	847	454	80
Other ^(e)	—	2	17


(a)	Impairment tests conducted on other intangible assets as of December 31, 2019 led to (i) the recognition of an impairment loss of € 2,236 million on the product Eloctate ^® (as part of the broader Eloctate ^® franchise) and (ii) an impairment loss of € 163 million on the marketed product Lemtrada ^® , versus € 183 million as of December 31, 2018.


(b)	The impairment loss recognized for the Vaccines segment in 2017 relates to intangible assets associated with the Dengue vaccine and arises from revisions to sales forecasts following results of long-term clinical trials and the resulting requirement to update the product label.


(c)	Impairment tests conducted on other intangible assets as of December 31, 2019 led to the recognition of an impairment loss of € 352 million on assets related to Zantac ^® .

(d)

The impairment losses recognized in 2019 relate mainly to (i) the allocation of the impairment loss recognized for the Eloctate ^® franchise to the BIVV001 project in accordance with paragraph 104 of IAS 36 (Impairment of Assets) (see (a) above) and (ii) the development program for sotaglifozin (€ 275 million).The impairment losses recognized in 2018 relate mainly to intangible assets of Ablynx and to other R&D intellectual property assets, including the MyoKardia and efpeglenatide programs in diabetes.


(e)	Not included within the line item Impairment of intangible assets in the consolidated income statements (see Note B.4.)

In 2019, competition intensified in the hemophilia A segment due to the arrival of new products in the market, especially in the United States. This led to a decrease in sales of Eloctate ^® during 2019. As a result, management updated the prospects for this franchise and conducted an impairment test as of June 30, 2019, followed by a further impairment test as of December 31, 2019 to take account of changes in market conditions during the second half of the year. Both tests were conducted in accordance with IAS 36 (Impairment of Assets).

The recoverable amount of those assets was determined on the basis of discounted cash flow projections over their economic lives (see Note B.6.1.). Based on the results of the impairment test conducted in the second half of 2019, an impairment loss of € 1,194 million was recognized against the Eloctate ^® franchise assets, in addition to the impairment loss of € 1,609 million recognized in the first half of 2019. As of December 31, 2019, those assets had a carrying amount of € 2,623 million net of impairment losses.

A 5 % decrease in the sales projections used to determine the recoverable amount as of December 31, 2019 would require an additional impairment loss of around € 150 million to be recognized. An increase of one-half of a percentage point in the discount rate used to determine the recoverable amount (after-tax rates of 7.25 % for the Eloctate ^® cash flow projections and 8.25 % for the BIVV001 cash flow projections) would require an additional impairment loss of € 107 million to be recognized. The valuation model used incorporates a probability assumption regarding the successful development and marketing approval of BIVV001, a long-acting factor VIII therapy (currently in Phase III) that is intended to succeed Eloctate ^® . If that project fails, an additional impairment loss of € 956 million would be required. If it succeeds, the sales projections used in the impairment test could be reduced by approximately 13 % without any further impairment loss being required .

Commercialization of Zantac ^® in the United States and Canada was halted during the second half of 2019, leading Sanofi to write down the related intangible asset to zero ; this resulted in the recognition of an impairment loss of € 352 million in the 2019 financial statements.

Property, plant and equipment

Impairment losses taken against property, plant and equipment are disclosed in Note D.3.

D.7.1 Equity instruments at fair value through other comprehensive income

Quoted equity investments

The main changes in the quoted equity investments included in the line “Equity instruments at fair value through other comprehensive income” are described below:

▪

Furthe r to the announcement on April 8, 2019 of amendments to the terms of the agreement governing Sanofi’s equity interest in Alnylam, on May 2, 2019 Sanofi divested its entire holding of 10.6 million of Alnylam shares, representing approximately 10 % of the company's capital. Proceeds from the divestment amounted to € 706 million , net of taxes. The loss on the divestment was recognized in full in Other comprehensive income . This equity interest had a carrying amount of € 671 million as of December 31, 2018.


▪	The entire equity interest held by Sanofi in MyoKardia, Inc. was divested during the first half of 2019. Proceeds from the divestment amounted to € 118 million , net of taxes. The gain arising on the divestment was recognized in full in Other comprehensive income . This equity interest had a carrying amount of € 178 million as of December 31, 2018.


▪	Following the restructuring of the collaboration with Onduo LLC finalized on November 11, 2019, Sanofi received from Onduo a dividend in the form of DexCom shares valued at $ 122 million . As of December 31, 2019, those shares had a carrying amount of € 104 million .

A 10% decline in stock prices of the quoted equity investments included within “Equity instruments at fair value through other comprehensive income” would have had a negative pre-tax impact of € 11 million on Other comprehensive income .

D.7.3. Other financial assets at fair value through profit or loss

The line item “Other financial assets at fair value through profit or loss ” includes:


▪	Contingent consideration receivable by Sanofi following the dissolution of the Sanofi Pasteur MSD joint venture, based on a percentage of MSD’s future sales during the 2017-2024 period of specified products previously distributed by SPMSD (see Notes B.1. and D.12.).

The fair value of the MSD contingent consideration was determined by applying the royalty percentage stipulated in the contract to discounted sales projections. A reduction of one percentage point in the discount rate would increase the fair value of the MSD contingent consideration by approximately 2 % .

Changes in the fair value of this contingent consideration are recognized in the income statement within the line item Fair value remeasurement of contingent consideration (see Note B.18.).

As of December 31, 2019 , the contingent consideration asset amounted to € 492 million (including a non-current portion of € 398 million ), versus € 373 million (non-current portion: € 309 million ) as of December 31, 2018 and € 342 million as of December 31, 2017 . The movement during 2019 was due primarily to an adjustment of € 178 million to the fair value of the asset to reflect revisions of sales forecasts.


▪	Finan cial assets held to meet obligations to employees under post-employment benefit plans, amounting to € 198 million as of December 31, 2017. Those obligations, and the financial assets held to meet them, were partially outsourced during 2017. They were exchanged for debt instruments during 2018 (see Note D.7.2.).


▪	A portfolio o f financial investments (amounting to € 442 million as of December 31, 2019) held to fund a deferred compensation plan provided to certain employees (versus € 363 million as of December 31, 2018 and € 359 million as of December 31, 2017 ).

The equity investments in Voyager Therapeutics, Inc. and Impact Therapeutics, Inc. that were recognized as available-for-sale financial assets as of December 31, 2017 were reclassified in accordance with IFRS 9 as other financial assets at fair value through profit or loss as of January 1, 2018.

(b)

In some countries, Sanofi is liable for withholding taxes and other tax charges when dividends are distributed. Consequently, Sanofi recognizes a deferred tax liability on the reserves of French and foreign subsidiaries (approximately € 47.2 billion ) which it regards as likely to be distributed in the foreseeable future. In determining the amount of the deferred tax liability as of December 31, 2019 , Sanofi took into account changes in the ownership structure of certain subsidiaries, and the effects of changes in the taxation of dividends in France following the ruling of the Court of Justice of the European Union in the Steria case and the resulting amendments to the 2015 Finance Act.


(c)	Includes deferred tax assets related to restructuring provisions, amounting to € 259 million as of December 31, 2019 , € 218 million as of December 31, 2018 , and € 212 million as of December 31, 2017 .


(d)	The 2019 variation of the line "Other" mainly includes the recognition of a deferred tax assets related to an internal transfer of intangible assets.

The reserves of Sanofi subsidiaries that would be taxable if distributed but for which no distribution is planned, and for which no deferred tax liability has therefore been recognized, totaled € 10.9 billion as of December 31, 2019 , compared with € 10.2 billion as of December 31, 2018 and € 16.8 billion as of December 31, 2017 .

Most of Sanofi’s tax loss carry-forwards are available indefinitely. For a description of policies on the recognition of deferred tax assets, refer to Note B.22. For each tax consolidation, the recognition of deferred tax assets is determined on the basis of profit forecasts that are consistent with Sanofi’s medium-term strategic plan, and taking into consideration the tax consequences of the strategic opportunities available to Sanofi within the period of availability of tax loss carry-forwards and the specific circumstances of each tax consolidation. Deferred tax assets relating to tax loss carry-forwards as of December 31, 2019 amounted to € 1,640 million , of which € 317 million were not recognized. This compares with € 1,651 million as of December 31, 2018 (of which € 310 million were not recognized) and € 1,346 million as of December 31, 2017 (of which € 287 million were not recognized).

(d)	Amounts reported within the income statement line item Fair value remeasurement of contingent consideration , and mainly comprising unrealized gains and losses.


(e)	Includes two potential payments of € 42 million each relating to the acquisition of Protein Sciences, contingent on the attainment of specified performance criteria subsequent to the acquisition date.


(f)	Includes € 226 million for contingent consideration liabilities in favor of True North Therapeutics and € 2 million of liabilities owed to Bioverativ employees at the acquisition date.

As of December 31, 2019 , Liabilities related to business combinations and to non-controlling interests mainly comprised:

▪

A liability arising from the acquisition of True North Therapeutics by Bioverativ. The former shareholders of True North Therapeutics are entitled to milestone payments contingent on the attainment of development, registration and sales objectives; the fair value of the resulting liability was measured at $ 258 million as of December 31, 2019 , compared with $ 192 million as of December 31, 2018 . That fair value is determined based on the contractual terms and on development and sales projections which have been weighted to reflect the probability of success, and discounted. If the discount rate were to fall by one percentage point, the fair value of the contingent consideration would increase by approximately 2 % .


▪	The Bayer contingent consideration liability arising from Sanofi's acquisition of Genzyme in 2011. As of December 31, 2019 , Bayer was still entitled to receive the following potential payments:


–	a percentage of sales o f alemtuzumab up to a maximum of $ 1,250 million or over a maximum period of 10 years, whichever is achieved first;


–	milestone payments based on specified levels of worldwide sales of alemtuzumab beginning in 2021 , unless Genzyme exercises its right to buy out those milestone payments by making a one-time payment not exceeding $ 900 million .




SANOFI / FORM 20-F 2019	F-65

NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS – (Continued)

The fair value of this liability was measured at € 156 million as of December 31, 2019 , compared with € 472 million as of December 31, 2018 and € 701 million as of December 31, 2017 . The fair value of the Bayer liability is determined by applying the contractual terms to sales projections which have been weighted to reflect the probability of success, and discounted. If the discount rate were to fall by one percentage point, the fair value of the Bayer liability would increase by approximately 2 % .

▪

The MSD contingent consideration liability arising from the 2016 acquisition of the Sanofi Pasteur activities carried on within the former Sanofi Pasteur MSD joint venture, which amounted to € 385 million as of December 31, 2019 , € 410 million as of December 31, 2018 and € 420 million as of December 31, 2017 (see Note D.12.). The fair value of this contingent consideration is determined by applying the royalty percentage stipulated in the contract to discounted sales projections.

T he table below sets forth the maximum amount of contingent consideration payable and firm commitments to buy out non-controlling interests:



December 31, 2019	Total	Payments due by period
(€ million)	Total	Less than 1 year	From 1 to 3 years	From 3 to 5 years	More than 5 years
Commitments relating to contingent consideration in connection with business combinations ^(a)	3,503	2,580	390	284	249


(a)	Includes € 0.4 billion for the Bayer contingent consideration and € 2.3 billion for the CVRs issued in connection with the acquisition of Genzyme. The CVR agreement is expected to be terminated in March 2020 following signature of a litigation settlement agreement (see Note D.22.).

The nominal amount of contingent consideration was € 3,638 million as of December 31, 2018 and € 4,223 million as of December 31, 2017 . The decrease in commitments during 2019 related mainly to those arising from the Genzyme acquisition (annual payments of the Bayer contingent consideration), and the effect of exchange rates on commitments denominated in US dollars.

D.19.1. Provisions for pensions and other post-employment benefits

Sanofi offers its employees pension plans and other post-employment benefit plans. The specific features of the plans (benefit formulas, fund investment policy and fund assets held) vary depending on the applicable laws and regulations in each country where the employees work. These employee benefits are accounted for in accordance with IAS 19 (see Note B.23.).

Sanofi’s pension obligations in four major countries represented approximately 89 % of the total value of the defined-benefit obligation and approximately 88 % of the total value of plan assets as of December 31, 2019 . The features of the principal defined-benefit plans in each of those four countries are described below.

NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS – (Continued)

France

Lump-sum retirement benefit plans

All employees working for Sanofi in France are entitled on retirement to a lump-sum payment, the amount of which depends both on their length of service and on the rights guaranteed by collective and internal agreements. The employee’s final salary is used in calculating the amount of these lump-sum retirement benefits. These plans represent approximately 41 % of Sanofi’s total obligation in France.

Defined-benefit pension plans

These plans provide benefits from the date of retirement. Employees must fulfil a number of criteria to be eligible for these benefits. All of these plans are now closed, the only plan still open to new entrants having been closed in 2019. These plans represent approximately 59 % of Sanofi’s total obligation in France.

Germany

Top-up defined-benefit pension plan

The benefits offered under this pension plan are wholly funded by the employer (there are no employee contributions) via a Contractual Trust Agreement (CTA), under which benefits are estimated on the basis of a career average salary. Employees are entitled to receive an annuity under this plan if their salary exceeds the social security ceiling. The amount of the pension is calculated by reference to a range of vesting rates corresponding to salary bands. The plan also includes disability and death benefits. This plan represents approximately 67 % of Sanofi’s total obligation in Germany.

Sanofi-Aventis plus (SAV plus)

A top-up pension plan (SAV plus) replaced a previous top-up defined-benefit plan. New entrants joining the plan after April 1, 2015 contribute to a defined-contribution plan that is partially funded via the company’s CTA.

All employees whose salary exceeds the social security ceiling are automatically covered by the plan. The employer’s contribution is 15 % of the amount by which the employee’s salary exceeds the social security ceiling.

Multi-employer plan (Pensionskasse)

This is a defined-benefit plan treated as a defined-contribution plan, in accordance with the accounting policies described in Note B.23. Currently, contributions cover the level of annuities. Only the portion relating to the future revaluation of the annuities is included in the defined-benefit pension obligation. The obligation relating to this revaluation amounted to € 694 million as of December 31, 2019 , versus € 673 million as of December 31, 2018 and € 699 million as of December 31, 2017 . This plan represents approximately 20 % of Sanofi’s total defined-benefit obligation in Germany.

United States

Defined-benefit pension plans

In the United States, there are two types of defined-benefit plan:

▪

“ Qualified ” plans within the meaning of the Employee Retirement Income Security Act of 1974 (ERISA), which provide guaranteed benefits to eligible employees during retirement, and in the event of death or disability. Employees can elect to receive a reduced annuity, in exchange for an annuity to be paid in the event of their death to a person designated by them. An annuity is also granted under the plan if the employee dies before retirement age. Eligible employees do not pay any contributions. These plans are closed to new entrants, and the vesting of rights for future service periods is partially frozen. These plans represent approximately 62 % of Sanofi’s total obligation in the United States.


▪	“Non- qualified ” plans within the meaning of ERISA provide top-up retirement benefits to some eligible employees depending on the employee’s level of responsibility and subject to a salary cap. These plans represent approximately 9 % of Sanofi’s total obligation in the United States.

Healthcare cover and life insurance

Sanofi companies provide some eligible employees with healthcare cover and life insurance during the retirement period (the company’s contributions are capped at a specified level). These plans represent approximately 29 % (or € 870 million ) of Sanofi’s total obligation and 3 % (or € 47 million ) of total plan assets in the United States.

United Kingdom

Defined-benefit pension plans

Sanofi operates a number of pension plans in the United Kingdom that reflect past acquisitions. The most significant arrangements are defined-benefit plans that have been closed since October 1, 2015. With effect from that date, employees can no longer pay into these plans.

Under these defined-benefit plans, an annuity is paid from the retirement date. This annuity is calculated on the basis of the employee’s length of service as of September 30, 2015, and of the employee’s final salary (or salary on the date he or she leaves Sanofi).

The rates used for the vesting of rights vary from member to member. For most members, rights vest at the rate of 1.25 % or 1.50 % of final salary for each qualifying year of service giving entitlement. The notional retirement age varies according to the category to which the member belongs, but in most cases retirement is at age 65 . Members may choose to retire before or after the notional retirement age ( 60 years), in which case the amount of the annual pension is adjusted to reflect the revised estimate of the length of the retirement phase. Pensions are usually indexed to the Retail Price Index (RPI). Members paid a fixed-percentage contribution into their pension plan (the percentage varied according to the employee category), and the employer topped up the contribution to the required amount. These plans represent approximately 100 % of Sanofi’s total obligation in the United Kingdom.

For service periods subsequent to October 1, 2015, employees belong to a new defined-contribution plan.

Actuarial assumptions used to measure Sanofi’s obligations

Actuarial valuations of Sanofi’s benefit obligations were computed by management with assistance from external actuaries as of December 31, 2019 , 2018 and 2017 .

Those calculations were based on the following financial and demographic assumptions:

Sanofi has a long-term objective of maintaining or increasing the extent to which its pension obligations are covered by assets. To this end, Sanofi uses an asset-liability management strategy, matching plan assets to its pension obligations. This policy aims to ensure the best fit between the assets held on the one hand, and the associated liabilities and expected future payments to plan members on the other. To meet this aim, Sanofi operates a risk monitoring and management strategy (mainly focused on interest rate risk and inflation risk), while investing a growing proportion of assets in high-quality bonds with comparable maturities to those of the underlying obligations and in contracts entered into with leading insurance companies to fund certain post-employment benefit obligations.

Provisions for employee termination benefits as of December 31, 2019 amounted to € 1,125 million (versus € 895 million as of December 31, 2018 and € 862 million as of December 31, 2017 ).

The provisions apply mainly to France, and relate to various early retirement plans:


▪	plans with termina tion of employment contracts, such as cessation of employment plans and end-of-career transition plans;

▪

plans without termina tion of employment contracts, such as the “Forward” end-of-career paid leave plan implemented in 2016; the "Horizon 2020" and "SAF 2019" (Sanofi Aventis France) plans implemented in 2019; and two other plans (relating to the entities Sanofi Recherche & Développement and BioPark by Sanofi) announced in 2019 for implementation in 2020. All those plans are wholly voluntary and include an end-of-career paid leave component and an external retraining component.

The provision includes the present values of:


▪	gross annu ities for self-funded plans;


▪	employer’s social security charges on early retirement annuities for all plans (outsourced and self-funded);


▪	the levy charge d on those annuities under the “Fillon” law (only for plans with termination of employment contracts).

The average residual holding periods under these plans were 1.72 years, 2.03 years and 2.12 years as of December 31, 2019 , 2018 and 2017 , respectively.

The main other countries covered by restructuring provisions are Germany and the United States.

Objectives of the use of derivative financial instruments

Sanofi uses derivative instruments to manage operating exposure to movements in exchange rates, and financial exposure to movements in interest rates and exchange rates (where the debt or receivable is not contracted in the functional currency of the borrower or lender entity). On occasion, Sanofi uses equity derivatives in connection with the management of its portfolio of equity investments.

Sanofi performs periodic reviews of its transactions and contractual agreements in order to identify any embedded derivatives, which are accounted for separately from the host contract in accordance with IFRS 9. Sanofi had no material embedded derivatives as of December 31, 2019 , 2018 or 2017 .

(a)	Includes future variable lease payments not recognized in Lease liabilities as of December 31, 2019. The principal commitment on this line is a new lease in the United States that will commence in 2021.


(b)	Lease commitments given to joint ventures are immaterial as of December 31, 2019.


(c)	These comprise irrevocable commitments to suppliers of (i) property, plant and equipment, net of down-payments (see Note D.3.) and (ii) goods and services. As of December 31, 2018 , irrevocable commitments amounted to € 6,549 million given and € ( 175 ) million received.


(d)	Irrevocable purchase commitments given as of December 31, 2019 include € 1,150 million of commitments to joint ventures.


(e)	Commitments related to R&D, and other commitments, amounted to € 954 million as of December 31, 2018 .


(f)	This line includes only contingent milestone payments on development projects in progress. The reduction relative to December 31, 2018 (when probable milestone payments amounted € 3,241 million ) is mainly due to the discontinuation of the collaboration with Lexicon.


(g)	This line excludes:

(i) commitments relating to projects in the research phase ( € 6.7 billion in 2019, € 6.8 billion in 2018) and payments contingent upon the attainment of sales targets once a product is commercialized ( € 10.6 billion in 2019, € 9.9 billion in 2018);

(ii) commitments received in respect of the additional profit-share of quarterly profits Sanofi is entitled to under the collaboration agreements on human therapeutic antibodies with Regeneron (see Note C.1.), provided this share of the quarterly profits is positive, not exceeding 10 % of the share of the quarterly profits paid to Regeneron and up to 50 % of Regeneron payment of cumulative development costs incurred by the parties in the collaboration. Such commitments received amount to € 2.7 billion as of December 2019 (€ 2.5 billion , in 2018) relative to a cumulative development costs of € 6.6 billion as of December 31, 2019 (comprising € 3.5 billion 100 % financed by Sanofi and € 3.1 billion financed 80 % Sanofi, 20 % Regeneron); and

(iii) commitments received under other agreements amounting to € 3.2 billion in 2019 ( € 2.4 billion in 2018), including discovery, development and commercialization agreements arising from (a) the acquisition of Ablynx on May 14, 2018 (see Note D.1.), amounting to € 1.1 billion as of December 31, 2019 ( € 0.9 billion in 2018) and (b) the sale to Celgene of Sanofi's equity interest in Impact Biomedicines in January 2018, amounting to € 0.5 billion as of December 31, 2019 ( € 0.6 billion in 2018).

Research and development license agreements

In pursuance of its strategy, Sanofi may acquire technologies and rights to products. Such acquisitions may be made in various contractual forms: acquisitions of shares, loans, license agreements, joint development, and co-marketing. These arrangements generally involve upfront payments on signature of the agreement, development milestone payments, and royalties. Some of these complex agreements include undertakings to fund research programs in future years and payments contingent upon achieving specified development milestones, the granting of approvals or licenses, or the attainment of sales targets once a product is commercialized.

The “Research and development license agreements” line comprises future service commitments to fund research and development or technology, and probable contingent milestone payments regarded as reasonably achievable (i.e. all potential milestone payments relating to projects in the development phase, for which the future financial consequences are known or probable and for which there is a sufficiently reliable estimate).

The only major agreement entered into by Sanofi in 2019 is described below:

On July 23, 2019 Sanofi signed an agreement with Roche to obtain the exclusive over-the-counter (OTC) rights to Tamiflu ^® for the prevention and treatment of influenza (flu) in the US. Under the terms of the agreement, Sanofi will be responsible for leading FDA negotiations for the OTC switch and subsequent exclusive marketing, scientific engagement and distribution of Tamiflu ^® in the US consumer health care market. Tamiflu ^® is currently sold in the US for prescription use by Genentech, a member of the Roche Group.

Other major agreements entered into by Sanofi in prior years are described below:

Other agreements

Sanofi has entered into two agreements, with Royalty Pharma (December 2014) and NovaQuest (December 2015), which have similar characteristics in that the partners jointly bear a portion of the remaining development costs of the project on a quarterly basis in return for royalties on future sales. These transactions are co-investments, whereby the partner acquires an interest in the jointly-developed product by providing funding towards the development program. Consequently, the amounts received by Sanofi will be recorded as a reduction in development costs, to the extent that the development costs incurred by Sanofi are recognized in profit or loss in accordance with the policies described in Note B.4.1. The commitments under these two agreements were altered by the following events that occurred in 2017:


▪	The products being developed under the December 2014 agreement with Royalty Pharma were launched in the United States and Europe, marking the end of the joint development programs.


▪	Sanofi announced the discontinuation of development on the Clostridium Difficile program on December 1, 2017, thereby cancelling any future commitments under the December 2015 joint development agreement with NovaQuest.

On February 27, 2017, Sanofi and Lonza announced a strategic partnership in the form of a joint venture to build and operate a large-scale mammalian cell culture facility for monoclonal antibody production in Visp, Switzerland. An initial investment of approximately € 0.3 billion to finance construction of the facility is being made 50 / 50 by the two partners. In addition, Sanofi could pay Lonza in the region of € 0.8 billion over the next fifteen years partly as its share of operating expenses and the cost of producing future batches, and partly to reserve capacity in the new facility.

In February 2014, pursuant to the “Pandemic Influenza Preparedness Framework for the sharing of influenza viruses and access to vaccines and other benefits” (still effective as of December 31, 2019 ), Sanofi Pasteur and the World Health Organization (WHO) signed a bilateral “Standard Material Transfer Agreement” (SMTA 2). This agreement stipulates that Sanofi Pasteur will, during declared pandemic periods, (i) donate 7.5 % of its real-time production of pandemic vaccines against any strain with potential to cause a pandemic, and (ii) reserve a further 7.5 % of such production on affordable terms. The agreement cancels and replaces all preceding commitments to donate pandemic vaccines to the WHO.

No other agreement or amendment falling within this category was entered into during the year ended December 31, 2019 .

D.21.3. Off balance sheet commitments relating to Sanofi entities and business combinations

Off balance sheet funding commitments to associates and joint ventures are disclosed in Note D.6.

The maximum amount of contingent consideration relating to business combinations is disclosed in Note D.18.

D.22. Legal and arbitral proceedings

Sanofi and its affiliates are involved in litigation, arbitration and other legal proceedings. These proceedings typically are related to product liability claims, intellectual property rights (particularly claims against generic companies seeking to limit the patent protection of Sanofi products), competition law and trade practices, commercial claims, employment and wrongful discharge claims, tax assessment claims, waste disposal and pollution claims, and claims under warranties or indemnification arrangements relating to business divestitures. Provisions related to legal and arbitral proceedings are recorded in accordance with the principles described in Note B.12.

Most of the issues raised by these claims are highly complex and subject to substantial uncertainties; therefore, the probability of loss and an estimation of damages are difficult to ascertain. Contingent liabilities are cases for which either we are unable to make a reasonable estimate of the expected financial effect that will result from ultimate resolution of the proceeding, or a cash outflow is not probable. In either case, a brief description of the nature of the contingent liability is disclosed and, where practicable, an estimate of its financial effect, an




SANOFI / FORM 20-F 2019	F-83

NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS – (Continued)

indication of the uncertainties relating to the amount and timing of any outflow, and the possibility of any reimbursement are provided in application of paragraph 86 of IAS 37.

In the cases that have been settled or adjudicated, or where quantifiable fines and penalties have been assessed, we have indicated our losses or the amount of provision accrued that is the estimate of the probable loss.

In a limited number of ongoing cases, while we are able to make a reasonable estimate of the expected loss or range of the possible loss and have accrued a provision for such loss, we believe that publication of this information on a case-by-case basis or by class would seriously prejudice the Company’s position in the ongoing legal proceedings or in any related settlement discussions. Accordingly, in those cases, we have disclosed information with respect to the nature of the contingency but have not disclosed our estimate of the range of potential loss, in accordance with paragraph 92 of IAS 37.

These assessments can involve a series of complex judgments about future events and can rely heavily on estimates and assumptions. Our assessments are based on estimates and assumptions that have been deemed reasonable by management. We believe that the aggregate provisions recorded for the above matters are adequate based upon currently available information. However, given the inherent uncertainties related to these cases and involved in estimating contingent liabilities, we could in the future incur judgments that could have a material adverse effect on our net income in any particular period.

Long term provisions are disclosed in Note D.19. They include:


▪	Provisions for product liability risks, litigation and other amount to € 1,334 million in 2019 . These provisions are mainly related to product liabilities, government investigations, competition law, regulatory claims, warranties in connection with certain contingent liabilities arising from business divestitures other than environmental matters and other claims.


▪	Provisions for environmental risks and remediation amount to € 737 million in 2019 , the majority of which are related to contingencies that have arisen from business divestitures.

a) Products

Sanofi Pasteur Hepatitis B Vaccine Product Litigation

Since 1996, more than 180 lawsuits have been filed in various French civil courts against Sanofi Pasteur and/or Sanofi Pasteur MSD S.N.C., the former French subsidiary of Sanofi, and the latter a joint venture company with Merck & Co., Inc. now terminated, for which past ongoing litigation is now managed by the originating party. In such lawsuits, the plaintiffs allege that they suffer from a variety of neurological disorders and autoimmune diseases, including multiple sclerosis and Guillain-Barré syndrome as a result of receiving the hepatitis B vaccine.

In January 2008, both the legal entity Sanofi Pasteur MSD S.N.C., and a corporate officer of this company, as well as a former corporate officer of Sanofi Pasteur, were placed under investigation in an ongoing criminal inquiry in France relating to alleged side effects caused by the hepatitis B vaccine. In March 2012, Sanofi Pasteur and its former pharmacist in charge (i.e. the deputy Chief Executive Officer) were placed under an “advised witness” ( "témoin assisté ") status. In March 2016, the investigating judges decided to dismiss the proceedings. Several civil parties appealed against this decision. In June 2018, the Prosecutor General requested confirmation of the dismissal. In June 2019, the Investigation Chamber of the Paris Court of Appeals confirmed the decision taken by the investigating judges in March 2016 to dismiss the proceedings . Several plaintiffs have decided to appeal such decision before the French Supreme Court ( Cour de cassation ).

In October 2017, the French Supreme Court ( Cour de cassation ) dismissed two appeals filed by the plaintiffs against two decisions of the Appeal Court of Paris ( Cour d’appel ).

In January 2018, the Appeal Court of Bordeaux found a causal link between hepatitis B vaccine and multiple sclerosis. Sanofi Pasteur Europe appealed this decision before the French Supreme Court ( Cour de cassation ). On July 4, 2019, the French Supreme Court the ( Cour de cassation ) cancelled the judgment of the Appeal Court of Bordeaux and referred the case back to the Appeal Court of Toulouse .

Plavix ^® Product Litigation in the US

In December 2019, the judge overseeing the Plavix ^® product liability Multidistrict Litigation (“MDL”) in the District of New Jersey recommended that this MDL be closed. We expect the Judicial Panel on MDL to accept this recommendation. The Plavix ^® product liability litigation has concluded favorably for the Company.

Taxotere ^® Product Litigation in the US

As of December 31, 2019 , there were approximately 10,628 plaintiffs in courts across the country, with approximately 892 of those plaintiffs being spouses who have filed loss of consortium claims.

Suits have been filed against affiliates of Sanofi under US state law for personal injuries allegedly sustained in connection with the use of Taxotere®. The actions are held in several jurisdictions, including the federal and/or state courts of Louisiana, New Jersey, California, and Delaware. A first bellwether trial took place in September 2019 and issued a verdict in Sanofi's favor. It is not possible, at this stage, to reliably assess the outcome of these lawsuits or the potential financial impact on the Company.

Taxotere ^® - Mississippi Attorney General Litigation in the US

In October 2018, the Attorney General for the State of Mississippi filed a civil action in Hinds County, Mississippi, Chancery Court against various Sanofi Defendants related to Taxotere ^® . The State asserts one cause of action based on the Mississippi Consumer Protection Act (“MCPA”) and seeks a permanent injunction prohibiting Defendants’ conduct and civil penalties of up to $ 10,000 for each violation. In December 2018, Sanofi removed the matter to the US District Court for the Southern District of Mississippi. It is not possible, at this stage, to assess reliably the outcome of this lawsuit or the potential financial impact on the Company.

Zantac ^® Litigation in the US

In September 2019, the US Food and Drug Administration (“FDA”) announced it was investigating the claims of an online pharmacy’s Citizen Petition that the medication Zantac ^® (the brand name for ranitidine) used for stomach burns contains or can generate the chemical N-nitrosodiméthylamine (“NDMA”), an alleged human carcinogen. As a precautionary measure, Sanofi initiated a voluntary recall of branded over-the-counter Zantac ^® in October 2019. Concurrent with FDA’s investigation, multiple personal injury lawsuits and class actions alleging that Zantac ^® causes various cancers and seeking damages for either alleged personal injuries or alleged economic injuries were filed. In addition, in November 2019, Sanofi received a Civil Investigative Demand (CID) related to this issue from the Arizona Attorney General. At this preliminary stage, Sanofi cannot reliably predict the outcome of the litigation or the potential impact on the Company.

Depakine ^® Product Litigation in France

As of December 31, 2019 , 69 families brought a civil claim involving approximately 118 people which have been exposed in utero to sodium valproate, and a class action based on 14 cases has been filed against a French affiliate of Sanofi seeking indemnification under French law for personal injuries allegedly sustained by children in connection with the use of sodium valproate by their mothers during pregnancy to treat their epilepsy (Depakine ^® ) or bipolar disorder condition (Depakote ^® ). These actions are held in several jurisdictions in France.

Thirteen lawsuits are being ruled on the merits. Most of them have been filed before the First Instance Courts of Paris and Nanterre. The exact scheduling of these proceedings is not yet known but some decisions may arise in the course of 2020.

In November 2019, the French Supreme Court issued a ruling quashing partially the November 2017 Orléans Appeal Court decision against Sanofi ordering payment of approximately € 2 million to the plaintiff and € 1 million to the CPAM ( Caisse Primaire d’Assurance Maladie ). It confirmed the decision of the Orléans Appeal Court on (i) the statute of limitation and (ii) on the causal link but it quashed the Appeal Court decision insofar as it did not rule on Sanofi’s argument on the exoneration cause relating “to compliance of the product with mandatory regulations issued by the public authorities”. Consequently, the question of defect and the exoneration causes as well as the evaluation of the injuries should be re-examined by the Paris Court of Appeal.

In July 2018, the French affiliate of Sanofi filed an action with the administrative tribunal seeking compensation from the French Ministry of Health for those damages paid under the above - mentioned decision. At this stage, the Tribunal may decide to put this request on hold until the ruling of the Paris Court of Appeal.

In the class action lawsuit filed by the APESAC ( Association des Parents d’Enfants souffrant du Syndrome de l’Anti-Convulsivant ) before the Paris Court, the judge denied claimant’s motion on interim measures in November 2017. APESAC lodged an appeal which was rejected by the Court of Appeal of Paris in October 2018. Hearings are expected to take place in Q2 2020.

The French government has, through the 2017 Finance law adopted on December 29, 2016, set up a public compensation scheme which is meant to compensate loss or injury actually suffered in relation to the prescription of sodium valproate and its derivatives. The compensation scheme entered into force on July 1, 2017. The French affiliate has raised issue of conflict of interest of certain appointed experts, which led to those experts being either removed or replaced as per administrative decision. The indemnification committee of the public compensation scheme has started to issue final opinions addressed to the French affiliate as being held liable for the damages either in full or in part along with the French State. The French affiliate rejected the committee’s opinions and has accordingly not offered indemnification to the claimants who will receive compensation from the ONIAM ( Office National d'Indemnisation des Accidents Médicaux ) as provided by the regulation governing it. Consequently, the ONIAM has indemnified several claimants and is now seeking for reimbursement from Sanofi by means of delivering payment enforcement orders.

In July 2019, the French affiliate of Sanofi filed several legal actions against the ONIAM and the French Ministry of Health before the Administrative Court of Montreuil (France) to oppose these payment enforcement orders. The Tribunal has declined to have jurisdiction on this matter . Sanofi has lodged appeals on this issue and has seized in parallel the civil court to safeguard its rights .

A change to the compensation scheme was introduced in the 2020 Finance Bill:

The Amendment merges the College of Experts with the Indemnification Committee and sets a presumption of lack of information of the mother since 1982 for malformation and since 1984 for neurodevelopment disorders. It also waives the exoneration cause for compliance with mandatory regulation and provides that past cases can be re-submitted for new assessment. Decrees are expected before the end of the second semester of 2020.

An investigation is ongoing in relation to several criminal complaints against person unknown filed in May 2015. Since February 3, 2020, the French affiliate has the status of “indicted party” which enables it to fully exercise its rights of defense.

It is not possible, at this stage, to assess reliably the outcome of these cases or the potential financial impact on the Company.

Dengvaxia ^® (Philippines)

In early 2018, several claims were filed in the Philippines by parents of deceased children whose deaths were allegedly due to vaccination with Dengvaxia ^® . Early March 2019, the Philippine Department of Justice (DOJ) prosecution panel announced it had found probable cause to indict six Sanofi employees / former employees and former Government officials for “reckless imprudence” resulting in homicides. Several criminal actions have been filed in court as a result of the DOJ finding probable cause for the cases to proceed. A Motion for Reconsideration (MR) was filed by Sanofi Pasteur Inc. (Philippines) and was dismissed in November 2019 for all respondents who filed the MR except for one . The remaining respondents have filed a further Petition for Review to the DOJ Secretary in December 2019 and the said petition remains pending.

b) Patents

Ramipril Canada Patent Litigation

Sanofi was involved in a number of legal proceedings involving companies which market generic Altace ^® (ramipril) in Canada. In 2004, Sanofi unsuccessfully brought Notice of Compliance proceedings (NOC proceedings) at the end of which eight manufacturers obtained marketing




SANOFI / FORM 20-F 2019	F-85

NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS – (Continued)

authorizations from the Canadian Minister of Health for generic versions of ramipril in Canada. Sanofi filed unsuccessful patent infringement actions against all those companies and ultimately Sanofi was liable for damages under Section 8. Sanofi made payment in complete satisfaction of those awards.

In June 2011, while the Section 8 damages action was proceeding in Federal Court, Apotex commenced an action in the Ontario Superior Court of Justice asserting damages under the Ontario Statute of Monopolies, the UK Statute of Monopolies, and the Trade-marks Act (the “Ontario Action”). The Ontario Action was stayed pending exhaustion of appeals in the Section 8 damages action and, despite having received full compensation in the Section 8 action, was reinitiated by Apotex after the conclusion of the appeals.

In June 2017, the Canadian Supreme Court determined that the legal principles applied in the ramipril invalidity decision were unsound and in 2018, Sanofi amended its pleadings to address this development.

On January 11, 2019, the motions judge denied Sanofi’s motion to seek summary judgment on the issue of applicability of the Statute of Monopolies in view of the allowed pleadings amendment. In view of the pleadings amendment and denial of summary judgment, the trial for this matter, originally expected for fall 2019, will now likely be delayed significantly.

Praluent ^® (alirocumab)-related Amgen Patent Litigation in the US

In 2014, Amgen filed four separate complaints against Sanofi and Regeneron in the US District Court for the District of Delaware (“District Court”) asserting patent infringement relating to Sanofi and Regeneron’s Praluent ^® product . Together these complaints allege that Praluent ^® infringes seven patents for antibodies targeting PCSK9 and seek injunctive relief and unspecified damages. In January 2016, Sanofi and Regeneron informed the District Court that they stipulated to infringement. In March 2016, the District Court granted Judgment as a Matter of Law (JMOL) of obviousness in favor of Amgen and JMOL on an aspect of willful infringement in favor of Sanofi and Regeneron. In addition, in 2016, a jury verdict upheld the validity of Amgen’s asserted claims of two patents. In January 2017, the District Court denied Sanofi’s and Regeneron’s motion for a new trial and their motion for JMOL and granted an injunction preventing the marketing, selling or manufacturing of Praluent® in the US during the term of the two Amgen patents starting from February 21, 2017.

In early February 2017, the US Court of Appeals for the Federal Circuit (“Federal Circuit”) stayed (suspended) the permanent injunction for Praluent ^® during Sanofi’s and Regeneron’s appeal of the validity judgment and injunction ruling in the Federal Circuit.

In October 2017, the Federal Circuit granted a new trial on certain validity issues (lack of written description and enablement), vacated (lifted) the District Court’s judgment and found that the District Court improperly granted a permanent injunction.

In February 2019, a jury from the US District Court for the District of Delaware upheld the validity of three of the five asserted claims of two Amgen patents. The jury agreed with Sanofi and Regeneron for two of the five asserted claims, finding they were invalid. On February 8, 2019, the District Court dismissed Amgen’s claim for willful infringement.

In August 2019 , the Court ruled in favor of Sanofi and Regeneron and found as a matter of law that Amgen’s remaining three asserted patent claims are invalid. This means that Sanofi and Regeneron have successfully invalidated all five asserted patent claims in the District Court. Amgen appealed to the Federal Circuit and the appeal is ongoing.

Praluent ^® (alirocumab)-related Amgen Patent Litigation in Europe

Amgen has filed three separate patent infringement lawsuits against Sanofi and Regeneron in Europe based on Amgen’s European patent EP2215124. In July 2016, Amgen filed a lawsuit in the UK High Court of Justice, Chancery Division Patents Court against five Sanofi entities and Regeneron alleging that alirocumab infringes its ‘124 (UK) patent, seeking injunctive relief and unspecified damages; Sanofi has counterclaimed invalidity. In February 2017, the UK action was stayed (suspended) on terms agreed by the parties.

In July 2016, Amgen filed a lawsuit in Germany in the Regional Court, Düsseldorf against three Sanofi entities and Regeneron alleging that alirocumab infringes its ‘124 (DE) patent, seeking injunctive relief and unspecified damages. In July 2019, the Regional Court of Düsseldorf ruled, finding infringement, and issued an injunction which requires Sanofi and Regeneron to stop marketing, selling, and manufacturing Praluent® in Germany. Sanofi and Regeneron appealed. Amgen enforced the injunction and Sanofi and Regeneron complied. Praluent® is no longer commercialized in Germany. The main hearing for Sanofi and Regeneron’s appeal is scheduled for April 2, 2020.

In September 2016, Amgen filed a lawsuit in France in the Tribunal de Grande Instance of Paris against two Sanofi entities and Regeneron alleging that alirocumab infringes its ‘124 (FR) patent, seeking injunctive relief, € 10 million in provisional damages and unspecified damages. Sanofi has counterclaimed invalidity.

In December 2019, Amgen filed a lawsuit in Italy in the Milan Court against three Sanofi entities alleging that alirocumab infringes its ‘124 (IT) patent, seeking injunctive relief and unspecified damages.

In December 2019, Amgen filed a lawsuit in the Netherlands in the Court of the Hague against two Sanofi entities alleging that alirocumab infringes its ‘124 (NL) patent, seeking injunctive relief and unspecified damages.

In December 2019, Amgen filed a lawsuit in Spain in the Barcelona Court against the Sanofi Spanish affiliate, alleging that alirocumab infringes its ‘124 (ES) patent, seeking injunctive relief and unspecified damages.

Praluent ^® (alirocumab)-related EPO Patent Oppositions

The European Patent Office (EPO) granted Amgen’s European Patent EP2215124 in February 2016. Also in February 2016, Sanofi filed an opposition with the EPO requesting the revocation of Amgen’s ’124 patent in its entirety for all contracting states on the grounds that the subject-matter of the opposed patent is not patentable. In November 2016, Sanofi filed a second opposition (in the name of three Sanofi affiliates named as defendants in the German infringement action - see above), and Regeneron filed a separate opposition, requesting revocation of Amgen’s ’124 patent. In November 2018, the EPO Opposition Division maintained Amgen’s patent claims in amended form. Subsequently, Sanofi and Regeneron each filed a notice of appeal.

Praluent ^® (alirocumab)-related Amgen Opposition and Patent Litigation in Japan

In May 2017, Amgen filed a lawsuit in the Tokyo District Court (TDC), against Sanofi K.K. for patent infringement of two of its Japanese Patents, JP5705288 and JP5906333. Amgen sought injunctive relief to prevent the infringing manufacture, use and sale of alirocumab, as well as destruction of Praluent ^® and alirocumab, and the cost of litigation. Sanofi had counterclaimed invalidity and non-infringement.

The validity of these two Japanese patents was separately challenged by Sanofi in the Japanese Patent Office (JPO) by filing invalidation actions in 2016. In August 2017, the JPO upheld the patents’ claims in amended form. In December 2017, Sanofi filed an appeal to the Intellectual Property High Court (IPHC) demanding revocation of the JPO decision. In December 2018, the IPHC rendered its decision that Amgen’s patents are valid, upholding the JPO’s earlier decision. Sanofi filed an appeal to the Supreme Court in February 2019.

In January 2019, the TDC ruled in Amgen’s favor, finding its patents valid and infringed. The TDC did not order provisional enforcement of an injunction. Sanofi appealed to the IPHC. In October 2019, the IPHC affirmed the TDC's decision that Amgen’s patents are valid and infringed. Sanofi filed an appeal to the Supreme Court in November 2019.

Dupixent ^® (dupilumab)-related Amgen Patent Opposition and Revocation in Europe

Immunex Corporation, an Amgen affiliate, is the registered proprietor of European Patent EP2292665. The claims of this patent relate to, among other things, human monoclonal antibodies that are capable of inhibiting IL-4 induced biological activity and which compete with one of four reference antibodies for binding to a cell that expresses human IL-4R. In April 2016, Sanofi and Regeneron each filed an opposition in the European Patent Office (EPO) against EP2292665, seeking its revocation on the basis that, inter alia, the claims are invalid for prohibited “added matter”, lack of novelty, lack of inventive step and lack of sufficient disclosure. In September 2016, Sanofi also filed a civil action in the UK High Court (Chancery Division/Patents Court) seeking revocation of the UK designation of EP2292665 on similar grounds. In January 2017, at the joint request of Sanofi and Immunex, the UK High Court ordered that the revocation action be stayed pending the final determination of the pending EPO opposition proceedings.

The EPO rendered its decision in November 2017 and revoked the patent in its entirety. The decision revoking the patent was issued in January 2018. In early 2018, Immunex appealed the decision of the EPO.

In September 2017, Sanofi and Regeneron filed oppositions in the EPO against Amgen’s European Patent EP2990420, which is a divisional of the EP2292665 Patent discussed above. The issues in this opposition were similar to those made in the oppositions against EP2292665.

In February 2019, the EPO revoked the patent EP2990420 in its entirety, finding the claims invalid for lack of sufficiency. Immunex filed a notice of appeal in May 2019. A hearing date for the appeal has not been scheduled yet.

Dupixent ^® (dupilumab)-related Amgen Inter Partes Reviews and Patent Litigation in the US

In March and July 2017, Sanofi and Regeneron filed collectively three petitions for Inter Partes Review (IPR) for US Patent No. 8,679,487 with the United States Patent and Trademark Office (USPTO). In these petitions, Sanofi and Regeneron collectively attack the validity of all the claims of this patent. The USPTO declined to institute an IPR on the first petition but granted Sanofi and Regeneron’s second and third petitions and instituted Inter Partes Reviews of all challenged claims in the ‘487 Patent.

In April 2017, Immunex filed a complaint in the US District Court for the Central District of California against Sanofi and Regeneron asserting that the commercialization of Dupixent infringes US Patent No. 8,679,487. In response, among other things, Sanofi and Regeneron asserted affirmative defenses of non-infringement, invalidity, and unenforceability.

In February 2019, the USPTO issued final written decisions on the two IPR petitions and declined to hold the challenged claims of the US patent No. 8,679,487 invalid for anticipation but found all claims on the ‘487 patent invalid for obviousness. In April 2019, Immunex appealed the USPTO’s decision invalidating all 17 claims of US Patent No. 8,679,487 to the Federal Circuit. Also in April 2019, Sanofi and Regeneron appealed the USPTO’s decision that the challenged claims of the ‘487 Patent are not invalid as anticipated by Immunex’s ‘132 Publication .

With respect to the Immunex complaint, on February 28, 2019, the US District Court granted parties’ joint stipulation seeking to stay (put on-hold) the district court litigation. Accordingly, the litigation is stayed pending final resolution of any rehearings or appeals of the related IPR proceedings.

Plavix ^® Litigation (Commonwealth) in Australia

In August 2007, GenRX (a subsidiary of Apotex) obtained registration of a generic clopidogrel bisulfate product on the Australian Register of Therapeutic Goods. At the same time, GenRX filed a patent invalidation action with the Federal Court of Australia, seeking revocation of Sanofi’s Australian enantiomer patent claiming clopidogrel salts (a “nullity action”). In September 2007, Sanofi obtained a preliminary injunction from the Federal Court preventing commercial launch of this generic clopidogrel bisulfate product until judgment on the substantive issues of patent validity and infringement. In February 2008, Spirit Pharmaceuticals Pty. Ltd. also filed a nullity action against Sanofi’s Australian enantiomer patent. The Spirit proceeding was consolidated with the Apotex proceeding.

In August 2008, the Australian Federal Court confirmed that the claim in Sanofi’s Australian enantiomer patent directed to clopidogrel bisulfate (the salt form in Plavix ^® ) was valid and the patent infringed. On appeal, the Full Federal Court of Australia held in September 2009 that all claims in the patent are invalid. Sanofi’s appeal to the Australia High Court was denied in March 2010. The security bond posted by Sanofi in connection with the preliminary injunction obtained in 2007 was subsequently increased from AUD 40 million to AUD 204 million ( € 25 million to € 128 million as of December 31, 2019 ). Apotex sought damages in the range of AUD 20 million to AUD 236 million ( € 12 million to € 148 million as of December 31, 2019 ), plus interest for having been subject to an injunction.

In April 2013, the Australian Department of Health and Ageing filed an application before the Federal Court of Australia seeking payment of damages from Sanofi related to the Apotex preliminary injunction of up to AUD 449 million ( € 281 million as of December 31, 2019 ), plus interest.

Sanofi and BMS settled the patent litigation with Apotex in November 2014. In light of the Apotex settlement, the Commonwealth has requested that the Court consider a set of legal issues separate from trial that could simplify the trial. In December 2015, the Court held that the relevant




SANOFI / FORM 20-F 2019	F-87

NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS – (Continued)

statute does not preclude the Commonwealth from seeking damages in cases such as this. Sanofi and BMS have applied for special leave to appeal against this decision. Sanofi’s special appeal to the High Court on the issue of the invalidity of the patent was denied in November 2015.

In May 2016, Sanofi’s and BMS’s application for special leave to appeal to the High Court of Australia was denied. Consequently, the substantive claim on damages sought by the Commonwealth has continued to trial. A decision is expected during the first half of 2020.

c) Other litigation and arbitration

CVR Trustee Claim

In November 2015, American Stock Transfer & Trust Company LLC (“AST”), the Trustee of the CVR Agreement between AST and Sanofi, dated March 30, 2011, filed a complaint against Sanofi in the US District Court for the Southern District of New York, alleging that Sanofi breached the CVR Agreement and the implied covenant of good faith and fair dealing, including by allegedly failing to use “Diligent Efforts,” as defined in the CVR Agreement, with respect to the regulatory approval and sale of Lemtrada ^® .

In June 2016, a new Trustee, UMB Bank, N.A. (“UMB”) was appointed.

On March 24, 2017, the Trustee sought leave to amend its complaint for a second time to assert a breach of contract claim with respect to the Production Milestone, which request was granted on August 23, 2017.

In October 2019, the Trustee and Sanofi entered into an agreement to settle the action for $ 315 million (the “Settlement Agreement”), which was previously disclosed in a Form 6-K filed by Sanofi on October 31, 2019. Among other things, the Settlement Agreement provides that the CVRs will be delisted from the NASDAQ and extinguished, and the CVR Agreement will be terminated. The Settlement Agreement was approved by the probate court for Hennepin County, Minnesota on December 20, 2019; the time for appeals expired on March 3, 2020.

This is only a summary of certain of the terms of the Settlement Agreement and is qualified in its entirety by the terms thereof. The Settlement Agreement was attached as an exhibit to Form 6-K.

d) Contingencies arising from certain Business Divestitures

Sanofi and its subsidiaries, Hoechst and Aventis Agriculture, divested a variety of mostly chemical, including agro-chemical, businesses as well as certain health product businesses. As a result of these divestitures, the Company is subject to a number of ongoing contractual and legal obligations regarding the state of the sold businesses, their assets, and their liabilities.

Aventis Behring Retained Liabilities

The divestment of Aventis Behring and related protein therapies assets became effective on March 31, 2004. The purchase agreement contained customary representations and warranties running from Sanofi as seller to CSL Limited as purchaser. Sanofi has indemnification obligations that generally expired on March 31, 2006 (the second anniversary of the closing date). However, some indemnification obligations, having a longer duration, remain in effect. For example, indemnification obligations relating to the due organization, capital stock and ownership of Aventis Behring Companies ran through March 31, 2014, and product liability indemnification ran through March 31, 2019, subject to an extension for claims related to certain types of product liability notified before such date. Furthermore, for tax-related issues, the indemnification obligation of Sanofi covers all taxable periods that end on or before the closing date and expires thirty days after the expiration of the applicable statute of limitations. In addition, the indemnification obligations relating to certain specified liabilities, including HIV liability, survive indefinitely.

Under the indemnification agreement, Sanofi is generally obligated to indemnify CSL Limited, only to the extent indemnifiable, losses exceeding $ 10 million and up to a maximum aggregate amount of $ 300 million . For environmental claims, the indemnification due by Sanofi equals 90 % of the indemnifiable losses. Product liability claims are generally treated separately, and the aggregate indemnification is capped at $ 500 million . Certain indemnification obligations, including those related to HIV liability, as well as tax claims, are not capped in amount.

Aventis CropScience Retained Liabilities

The sale by Aventis Agriculture S.A. and Hoechst GmbH (both legacy companies of Sanofi) of their aggregate 76 % participation in Aventis CropScience Holding (ACS) to Bayer and Bayer CropScience AG (BCS), the wholly owned subsidiary of Bayer which holds the ACS shares, was effective on June 3, 2002. The Stock Purchase Agreement (SPA) dated October 2, 2001, contained customary representations and warranties with respect to the sold business, as well as a number of indemnifications, in particular with respect to: environmental liabilities (the representations and warranties and the indemnification are subject to a cap of € 836 million , except for certain legal representations and warranties and specific environmental liabilities); taxes; certain legal proceedings; claims related to StarLink ^® corn; and certain pre-closing liabilities, in particular, product liability cases (which are subject to a cap of € 418 million within the above global cap of € 836 million ). There are various periods of limitation depending upon the nature or subject of the indemnification claim. Further, Bayer and BCS are subject to a number of obligations regarding mitigation and cooperation.

Since December 2005, Aventis Agriculture and Hoechst GmbH have concluded several settlement agreements to resolve a substantial number of disputes with Bayer and BCS, including the termination of arbitration proceedings initiated in August 2003 for an alleged breach of a financial statement-related representation contained in the SPA, and numerous other warranty and indemnification claims, including certain environmental and product liabilities claims. A number of other outstanding claims remain unresolved.

LLRICE601 and LLRICE604 - Arbitration

On December 19, 2014, BCS initiated a claim for arbitration against Aventis Agriculture S.A. and Hoechst GmbH seeking indemnification under various provisions of the SPA, with a demand for € 787.5 million . Bayer was seeking indemnification for damages allegedly suffered in several hundred individual complaints and lawsuits by rice growers, millers and distributors arising in US state and federal courts against a number of CropScience companies, formerly part of ACS before its divestiture, following the detection in 2006 of trace amounts of genetically-modified rice (the Liberty Link ^® Rice 601 and 604) in samples of commercial long grain rice. Bayer alleged that it had incurred losses in excess of $ 1.2 billion in judgments, settlements and litigation costs. The final claimed amount of € 693 million plus interest corresponded to the residual portion of the indemnification available under the SPA.




F-88	SANOFI / FORM 20-F 2019

NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS – (Continued)

Sanofi had opposed Bayer’s request for indemnification in an arbitration proceeding before DIS (German Arbitral Tribunal).

In July 2019, the DIS rendered its final decision under which it dismissed Bayer CropScience’s (BCS) claims in their entirety and awarded Sanofi reimbursement of all its legal costs. This case is over.

Aventis Animal Nutrition Retained Liabilities

Aventis Animal Nutrition S.A. and Aventis (both legacy companies of Sanofi) signed an agreement for the sale to Drakkar Holdings S.A. of the Aventis Animal Nutrition business effective in April 2002. The sale agreement contained customary representations and warranties. Sanofi’s indemnification obligations ran through April 2004, except for environmental indemnification obligations (which ran through April 2012), tax indemnification obligations (which run through the expiration of the applicable statutory limitation period), and antitrust indemnification obligations (which extend indefinitely). The indemnification undertakings are subject to an overall cap of € 223 million , with a lower cap for certain environmental claims. Indemnification obligations for antitrust and tax claims are not capped.

Celanese AG Retained Liabilities

The demerger of the specialty chemicals business from Hoechst to Celanese AG (now trading as “Celanese GmbH”) became effective on October 22, 1999. Under the demerger agreement between Hoechst and Celanese, Hoechst expressly excluded any representations and warranties regarding the shares and assets demerged to Celanese. Celanese subsequently contributed rights and obligations relating to environmental liabilities resulting from the demerger agreement to a subsidiary CCC Environmental Management and Solutions GmbH &

▪

While all obligations of Hoechst (i) resulting from public law or (ii) pursuant to current or future environmental laws or (iii) vis-à-vis third parties pursuant to private or public law related to contamination (as defined) were transferred to Celanese under the demerger agreement in full, after the subsequent contribution CCC can request indemnification from Hoechst for two thirds of any such cost incurred under these obligations.

▪

To the extent Hoechst is liable to purchasers of certain of its divested businesses (as listed in the demerger agreement), CCC is liable to indemnify Hoechst, as far as environmental damages are concerned, for aggregate liabilities up to € 250 million , liabilities exceeding such amount will be borne by Hoechst alone up to € 750 million , and amounts exceeding € 750 million will be borne 2/3 by Hoechst and 1/3 by CCC without any further caps. Subsequent to the contribution of rights and obligations relating to environmental liabilities by Celanese, Celanese was jointly liable with CCC until November 2016. Thereafter, Celanese remains liable for known environmental claims specified in 2013.

Rhodia Shareholder Litigation

In January 2004, two minority shareholders of Rhodia and their respective investment vehicles filed two claims before the Commercial Court of Paris ( Tribunal de Commerce de Paris ) against Aventis, to which Sanofi is successor in interest, together with other defendants including former directors and statutory auditors of Rhodia from the time of the alleged events. The claimants seek a judgment holding the defendants collectively liable for alleged management errors and for alleged publication of misstatements between 1999 and 2002, and inter alia regarding Rhodia’s acquisition of the companies Albright & Wilson and ChiRex. These shareholders seek a finding of joint and several liability for damages to be awarded to Rhodia in an amount of € 925 million for alleged harm to it (a derivative action), as well as personal claims of € 4.3 million and € 125.4 million for their own alleged individual losses. Sanofi contests both the substance and the admissibility of these claims.

Sanofi is also aware of three criminal complaints filed in France by the same plaintiffs and of a criminal investigation order issued by the Paris public prosecutor following the submission of the report issued by the AMF regarding Rhodia’s financial communications. In 2006, the Commercial Court of Paris accepted Sanofi’s and the other defendants’ motion to stay the civil litigation pending the conclusion of the criminal proceedings.

In December 2016, the Court of Appeals of Paris dismissed the appeal lodged by the same plaintiffs against the order of the investigating judge dated October 2015, dismissing all criminal charges in this case. The plaintiffs appealed the December 2016 decision before the French Supreme Court ( Cour de cassation ). Following this decision, the plaintiffs may also petition the Commercial Court of Paris and seek the reopening of the commercial cases mentioned above on the basis that the criminal proceedings have now concluded.

Clariant Retained Liabilities - Specialty Chemicals Business

Hoechst conveyed its specialty chemicals business to Clariant AG (Clariant) pursuant to a 1997 agreement. Clariant has undertaken to indemnify Hoechst for all costs incurred for environmental matters relating to purchased sites. However, certain indemnification obligations of Hoechst for environmental matters in favor of Clariant remain with Hoechst.

Hoechst must indemnify Clariant indefinitely (i) with respect to sites taken over by Clariant, for costs which relate to environmental pollutions attributable to certain activities of Hoechst or of third parties, (ii) for costs attributable to four defined waste deposit sites in Germany which are located outside the sites taken over by Clariant (to the extent exceeding an indexed amount of approximately € 20.5 million ), (iii) for costs from certain locally concentrated pollutions in the sites taken over by Clariant but not caused by specialty chemicals activities in the past, and (iv) for 75 % of the costs relating to a specific waste deposit site in Frankfurt, Germany.

Infraserv Hoechst Retained Liabilities

By the Asset Contribution Agreement dated December 19/20, 1996, as amended in 1997, Hoechst contributed all lands, buildings, and related assets of the Hoechst site at Frankfurt Hoechst to Infraserv GmbH & Co. Hoechst KG. Infraserv Hoechst undertook to indemnify Hoechst against environmental liabilities at the Hoechst site and with respect to certain landfills. As consideration for the indemnification undertaking, Hoechst transferred to Infraserv Hoechst approximately € 57 million to fund reserves. In 1997, Hoechst also agreed it would reimburse current and future Infraserv Hoechst environmental expenses up to € 143 million . As a former operator of the land and as a former user of the landfills, Hoechst may ultimately be liable for costs of remedial action in excess of this amount.

Boehringer Ingelheim (BI) Retained Liabilities

Following the closing in January 2017 of the swap of Sanofi’s Animal Health (AH) business for Boehringer Ingelheim (BI)’s Consumer Healthcare (CHC) business, both parties have issued claims against one another for breaches of representations, payments for certain studies, withdrawal of products from particular markets, and claims related to liabilities arising before Closing. The asset swap deal was structured such that the Consumer Health sale and purchase agreement and the Animal Health sale and purchase agreement are nearly identical and have mirroring indemnification provisions.

Following discussions between Sanofi and BI, the parties determined that it was in their mutual benefit to negotiate a settlement to:


▪	fully and finally settle the noticed indemnification claims under the SPAs and certain Ancillary Agreements,


▪	li mit the scope of indemnification obligations only for the reserved claims listed in the settlement,


▪	list the covenants surviving th e signature of the Settlement to be complied with by the parties.

In September 2019, a Global Settlement Agreement was signed and under this agreement, BI and Sanofi agreed that the settled AH and CHC claims were set-off against each other.

After the settlement, BI notified a claim to Sanofi requesting indemnification for its loss related to the Zantac ^® product liability cases, which Sanofi rejected.

(a)	The results of the Animal Health business are presented separately in accordance with IFRS 5 (Non-Current Assets Held for Sale and Discontinued Operations) (see Note D.2.).


(b)	The difference between the French tax rate and tax rates applicable to foreign subsidiaries reflects the fact that Sanofi has operations in many countries, most of which have lower tax rates than France.


(c)	For 2017, this line includes the consequences of the French Constitutional Council ruling of October 6, 2017 on the additional 3 % contribution on dividends paid out in cash.

(d)

For 2018, this line reflects an adjustment of € 188 million to the estimated tax charge on deemed repatriation attributable to the accumulated earnings of non-US operations. For 2017, this line reflects the effects of an expense of € 1,193 million for the consequences of US tax reform, comprising the estimated tax charge on deemed repatriation attributable to the accumulated earnings of non-US operations payable over 8 years ( € 1,084 million ) and a further expense of € 109 million representing (i) the remeasurement of deferred taxes following the reduction in the corporate income tax rate and (ii) an adjustment to deferred taxes on the fair value of the reserves of Sanofi subsidiaries.


(e)	This line includes the impacts related to the MSD contingent consideration and to the CVRs issued in connection with the acquisition of Genzyme.

(f)

For 2019 , “Other items” includes the impacts of current tax and deferred tax adjustments related to the 2018 financial year. In determining the amount of the deferred tax liability for 2019 , 2018 and 2017 , Sanofi took into account changes in the ownership structure of certain subsidiaries. For 2018, "Other items" includes the net tax effect of taxable temporary differences associated with holdings in Sanofi subsidiaries. For 2017 , the “Other items” line includes the impact of changes to tax rates in France, Belgium and the Netherlands.

For the periods presented, the amount of deferred tax assets recognized in profit or loss that were initially subject to impairment losses at the time of a business combination is immaterial.

D.31. Share of profit/loss from investments accounted for using the equity method

The line item Share of profit/(loss) from investments accounted for using the equity method comprises:



(€ million)	2019	2018	2017
Regeneron ^(a)	245	484	82
BMS co-promotion entities ^(b)	5	12	13

(b)	Share of co-promotion profits attributable to Sanofi for territories covered by entities majority owned by BMS (see Note C.2.).

The share of profits from Regeneron amounted to € 245 million in 2019 compared with € 484 million in 2018 ; the decrease was attributable mainly to lower corporate profits at Regeneron after adjustment to align on Sanofi accounting policies.

D.32. Net income attributable to non-controlling interests

The table below shows Net income attributable to non-controlling interests for the reporting periods presented:


(a)	For 2018 and 2017: share of co-promotion profits attributable to BMS for territories covered by entities majority owned by Sanofi (see Note C.2.); there is no tax effect on these amounts because BMS receives its share before tax. The payment made to buy out the BMS non-controlling interests was made on December 31, 2018 (see Note C.2.).

D.33. Related party transactions

The principal related parties are companies over which Sanofi has control or significant influence; joint ventures; key management personnel; and principal shareholders.




F-94	SANOFI / FORM 20-F 2019

NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS – (Continued)

Sanofi has not entered into any material transactions with any key management personnel. Financial relations with Sanofi’s principal shareholders fall within the ordinary course of business and were immaterial in the years ended December 31, 2019 , 2018 and 2017 .

Note F.1. lists the principal companies controlled by Sanofi; those companies are fully consolidated, as described in Note B.1. Transactions between those companies, and between the parent company and its subsidiaries, are eliminated when preparing the consolidated financial statements.

Transactions with companies over which Sanofi has significant influence, and with joint ventures, are presented in Note D.6.

Key management personnel include corporate officers (including one director holding office for four months in 2017 who was covered by a top-up pension plan: see “Item 6.B. - Compensation”) and the members of the Executive Committee (an average of 15 members in 2019 , 15 members in 2018 and 13 members in 2017 ).

The table below shows, by type, the compensation paid to key management personnel:



(€ million)	2019		2018	2017
Short-term benefits ^(a)	31		38	31
Post-employment benefits ^(b)	( 16	)	9	8
Share-based payment	30		33	15
Total recognized in profit or loss	45		80	54


(a)	Compensation, employer’s social security contributions, directors’ attendance fees, and any termination benefits (net of reversals of termination benefit obligations).


(b)	This line item includes in 2019 the favorable impact of top-up pension plan amendments following the application of the Pacte law in France.

The table below shows (i) the aggregate top-up pension obligation in favor of certain corporate officers who hold or have held executive positions within Sanofi and of Executive Committee members, and (ii) the aggregate amount of termination benefits and lump-sum retirement benefits payable to key management personnel.

D.34. Disclosures about major customers and credit risk

Credit risk is the risk that customers (wholesalers, distributors, pharmacies, hospitals, clinics or government agencies) may fail to pay their debts. Sanofi manages credit risk by vetting customers in order to set credit limits and risk levels, and asking for guarantees or insurance where necessary; performing controls; and monitoring qualitative and quantitative indicators of accounts receivable balances, such as the period of credit taken and overdue payments.

Customer credit risk also arises as a result of the concentration of Sanofi’s sales with its largest customers, in particular certain wholesalers in the United States. Sanofi’s three largest customers respectively accounted for approximately 8 % , 5 % and 3 % of consolidated revenues in 2019 ( 9 % , 6 % and 4 % in 2018 ; 9 % , 5 % and 4 % in 2017 ).

D.35. Segment information

As indicated in Note B.26., Sanofi has three operating segments: Pharmaceuticals, Consumer Healthcare and Vaccines.

The Pharmaceuticals segment comprises the commercial operations of the following global franchises: Specialty Care (Rare Diseases, Multiple Sclerosis, Oncology, Immunology and Rare Blood Disorders) and Primary Care (Diabetes, Cardiovascular and Established Prescription Products), together with research, development and production activities dedicated to the Pharmaceuticals segment. This segment also includes associates whose activities are related to pharmaceuticals, in particular Sanofi's share of Regeneron.

The Consumer Healthcare segment comprises, for all geographical territories, the commercial operations for Sanofi's Consumer Healthcare products, together with research, development and production activities dedicated to those products.

The Vaccines segment comprises, for all geographical territories (including certain territories previously included in the Sanofi Pasteur MSD joint venture) the commercial operations of Sanofi Pasteur, together with research, development and production activities dedicated to vaccines.

Inter-segment transactions are not material.

The costs of global support functions (Medical Affairs, External Affairs, Finance, Human Resources, Legal Affairs, Information Solutions & Technologies, Sanofi Business Services, etc.) are managed centrally at group-wide level. The costs of those functions are presented within the “Other” category. That category also includes other reconciling items such as retained commitments in respect of divested activities.

Sanofi reports segment results on the basis of “Business operating income”. This indicator is used internally by Sanofi’s chief operating decision maker to measure the performance of each operating segment and to allocate resources.

Business operating income is derived from Operating income , adjusted as follows:


▪	the amounts reported in the line items Restructuring costs and similar items , Fair value remeasurement of contingent consideration and Other gains and losses, and litigation are eliminated;


▪	amortization and impairment losses charged against intangible assets (other than software and other rights of an industrial or operational nature) are eliminated;


▪	the share of profits/losses from investments accounted for using the equity method is added;


▪	net income attributable to non-controlling interests is deducted;


▪	other acquisition-related effects (primarily the workdown of acquired inventories remeasured at fair value at the acquisition date, and the impact of acquisitions on investments accounted for using the equity method) are eliminated;


▪	restructuring co sts relating to investments accounted for using the equity method are eliminated;


▪	depreciation expense on right-of-use assets (IFRS 16) is eliminated, and rental expense (IAS 17) is deducted. Because Sanofi has elected first-time application of IFRS 16 using the simplified retrospective method, this adjustment ensures comparability of segment results between December 31, 2019 and comparative periods.
