•	Fortress brands with leading positions, some of which have been in use for more than 100 years


•	Far-reaching global distribution networks consisting of direct sales forces and independent channel

partners that collectively serve a diverse customer base in approximately 150 countries


•	A substantial installed base that provides for steady recurring revenue


•	A strong financial position and cash generation profile that enables us to fund strategic organic and inorganic growth initiatives, and consistently return capital to shareholders

Key pillars of our long-term strategy include (1) accelerate profitable growth; (2) increase profitability by driving continuous improvement initiatives; (3) leadership and talent development; and (4) focus on execution and accountability.

Company History and Certain Relationships

On October 31, 2011 (the "Distribution Date"), ITT completed the Spin-off (the “Spin-off”) of Xylem, formerly ITT’s water equipment and services businesses. The Spin-off was completed pursuant to a Distribution Agreement, dated as of October 25, 2011 (the “Distribution Agreement”), among ITT (now ITT LLC), Exelis Inc., acquired by Harris Inc. on May 29, 2015, (“Exelis”) and Xylem.

On October 31, 2016, Xylem Inc. completed the acquisition of all of the direct and indirect subsidiaries of Sensus Worldwide Limited (other than Sensus Industries) (“Sensus”), pursuant to the terms of the Share Purchase Agreement dated as of August 15, 2016, and the first Amendment to the Share Purchase Agreement dated as of October 31, 2016 (together, the “Purchase Agreement”). The aggregate consideration paid for the acquisition was approximately $ $1,766 million ( $1,710 million net of cash acquired).

Our Industry

Our planet faces serious water challenges. Less than 1% of the total water available on earth is fresh water, and these supplies are under threat due to factors such as the draining of aquifers, increased pollution and the effects of climate change. Demand for fresh water is rising rapidly due to population growth, industrial expansion, and increased agricultural development, with consumption estimated to double every 20 years. By 2025, more than 30% of the world’s population is expected to live in areas without adequate water supply. Even in developed countries with sufficient clean water supply, existing infrastructure for water supply is aging and inadequately funded. In the United States, deteriorating pipe systems, theft or inaccurate meters result in approximately one out of every six gallons of water being lost between the treatment plant and the end customer. This problem of "non-revenue" water is a major financial challenge of many utilities globally, especially in developing markets where non-revenue water can represent 15% to 60% or more of net water produced. These and other challenges create opportunities for growth in the global water industry. We estimate the total addressable market size to be approximately $550 billion .

We compete in areas that are pivotal to improving water productivity, water quality and resilience. Water productivity refers to the more efficient delivery and use of clean water. Water quality refers to the efficient and effective management of wastewater. Resilience refers to the management of water-related risks and the resilience of water infrastructure. Our customers often face all three of these challenges, ranging from inefficient and aging water distribution networks (which require increases in “water productivity”); energy-intensive or unreliable wastewater management systems (which require increases in “water quality”); or exposure to natural disasters such as floods or droughts (which require increases in “resilience”). Additionally, through the 2016 acquisition of Sensus, we also provide solutions to enhance efficiency, improve safety and conserve resources to customers in the electric, gas, and lighting sectors. Delivering value in these areas creates significant opportunity for the Company. We estimate our total served market size to be approximately $54 billion.

The Global Water Industry Value Chain

The water industry value chain includes Equipment and Services companies, like Xylem, which address the unique challenges and demands of a diverse customer base. This customer base includes utilities that supply water through an infrastructure network, and engineering, procurement and construction or (EPC) firms, which work with utilities to design and build water and wastewater infrastructure networks, as depicted below. Utilities and EPC customers are looking for technology and application expertise from their Equipment and Services providers to address trends such as rising pollution, stricter regulations, and the increased outsourcing of process knowledge. In addition to utilities and EPC customers, Equipment and Service providers also provide distinct technologies to a wide array of entities, including farms, mines, power plants, industrial facilities and residential and commercial customers seeking to address similar trends.

Water Industry Supply Chain

Water Infrastructure

Our Water Infrastructure segment supports the process that collects water from a source, treats it and distributes it to users, and then treats and returns the wastewater responsibly to the environment through two closely linked applications: Transport and Treatment . The Transport application also includes sales and rental of specialty dewatering pumps and related equipment and services, which provide the safe removal or draining of groundwater and surface water from a riverbed, construction or other industrial sites and bypass pumping for the repair of aging public utility infrastructure, as well as emergency water removal during severe weather events.

The customer base consists of two primary end markets: water utility and industrial. The water utility market includes public, private and public-private entities that support water and wastewater networks. The industrial market includes customers who require similar water and wastewater infrastructure networks to support various industrial operations.

Water Infrastructure provides the majority of its sales through direct channels with remaining sales through indirect channels and service capabilities. Both water utility and industrial facility customers increasingly require our teams’ global but locally proficient expertise to use our equipment in their specific applications. Several trends are increasing demand for this application expertise: (i) the increase in both the type and amount of contaminants found in the water supply, (ii) increasing environmental regulations, (iii) the need to increase system efficiencies to optimize energy costs, (iv) the retirement of a largely aging water industry workforce that has not been systematically replaced at utilities and other end-user customers, and (v) the build-out of water infrastructure in the emerging markets. We estimate our served market size in this sector to be approximately $17 billion.

Given the highly fragmented nature of the water industry, the Water Infrastructure segment competes with a large number of businesses. We differentiate ourselves in the market by focusing on product performance, reliability

and innovation, application expertise, brand reputation, energy efficiency, product life-cycle cost, timeliness of delivery, proximity of service centers, effectiveness of our distribution channels and price. In the sale or rental of products and provision of services, we benefit from our large installed base, which requires maintenance, repair and replacement parts due to the critical application and nature of the products and the conditions under which they operate. Timeliness of delivery, quality and the proximity of service centers are important customer considerations when selecting a provider for after-market products and services as well as equipment rentals. In geographic regions where we are locally positioned to provide a quick response, customers have historically relied on us, rather than our competitors, for after-market products relating to our highly engineered and customized solutions. Our key competitors within the Water Infrastructure segment include KSB Inc., Sulzer Ltd., Evoqua Water Technologies, United Rentals and Danaher Corporation.

Applied Water

Applied Water encompasses the uses of water and serves a diverse set of end markets including: residential, commercial, and industrial. Residential consumers represent the end users in the residential market, while owners and managers of properties such as apartment buildings, retail stores, institutional buildings, restaurants, schools, hospitals and hotels are examples of end users in the commercial market. The industrial market includes OEMs, exploration and production firms, and developers and managers of industrial facilities, such as electrical power generators, chemical manufacturers, machine shops, clothing manufacturers, beverage dispensing and food processing firms, and car washes.

In the Applied Water segment, end markets vary widely and, as a result, specialized distribution partners are often preferred. As such, the Applied Water segment provides the majority of its sales through strong indirect channels with the remaining sales going through our global direct sales channels. We have long-standing relationships with many of the leading independent distributors in the markets we serve, and we provide incentives to distributors, such as specialized loyalty and training programs.

We estimate our served market size in this sector to be approximately $19 billion. Population growth, urbanization and regulatory requirements are macro growth drivers of these markets, driving the need for housing, food, community services and retail goods within growing city centers.

Competition in the Applied Water segment focuses on brand equity, application expertise, product delivery and performance, quality, and price. We compete by offering a wide variety of innovative and high-quality products, coupled with world-class application expertise. We believe our distribution through well-established channels and our reputation for quality significantly enhance our market position. Our ability to deliver innovative product offerings has enabled us to compete effectively, to cultivate and maintain customer relationships and to serve and expand into many niche and new markets. Our key competitors within the Applied Water segment include Grundfos, Wilo SE, Pentair Ltd. and Franklin Electric Co., Inc.

Measurement & Control Solutions

Measurement & Control Solutions develops advanced technology solutions that enable intelligent use and conservation of critical water and energy resources. The segment delivers communications, smart metering, measurement and control technologies and services that allow customers to more effectively use their distribution networks for the delivery of critical resources such as water, electricity and natural gas. We also provide analytical instrumentation used to measure water quality, flow and level in wastewater, surface water and coastal environments. Additionally, we sell software and services including cloud-based analytics, remote monitoring and data management, leak detection and pressure monitoring solutions, as well as smart lighting products and solutions that improve efficiency and public safety efforts across communities.

At the heart of our leading technologies is automation and information. Communications networks automate and optimize meter reading, monitor flow rates and detect and enable rapid response to unsafe conditions. In short, they provide insight into operations and enable our customers to manage the entire scope of their operations remotely through their networks. At the center of our offering is the FlexNet communication network, which provides a common communications platform and infrastructure for essential services. This two-way communication technology remotely connects a wide variety of smart points in a given network with protocols, frequently on FCC licensed spectrum that enable reliable, resilient and secure transmissions. These technologies allow our customers to remotely and continuously monitor infrastructure, prioritize and manage maintenance and use data to optimize all aspects of their networks.

The majority of our sales in the U.S. is conducted through strong, long-standing relationships with leading distributors and dedicated channel partners for water, gas and electric markets. Internationally, direct sales are often made in markets without established distribution channels; however, some distribution channels are used in

more developed markets. A more direct sales approach, with key account management, is employed for large utilities and government programs.

We estimate our served market size in this sector to be approximately $18 billion. Macro growth drivers include increasing regulation and worldwide movement towards smart grid implementation. Water scarcity and conservation, as well as the need to prevent revenue loss (via inaccurate meter readings, leaks or theft) are among the drivers of smart meter and leak detection technologies.

Our Sensus-branded meters are well positioned in the smart metering sector, the fastest growing sector of the global meter industry. We set ourselves apart in the industry by focusing on our communication network, new product development and service offerings that are driving tangible savings of non-revenue water through improved meter accuracy, reduced theft and identification of leaks. Our key competitors within the Measurement & Control Solutions segment include Itron, Badger Meter, Landis+Gyr, Neptune (Roper) and Elster (Honeywell).

Supply and Seasonality

We have a global manufacturing footprint, with production facilities in Europe, North America, Latin America, and Asia. Our inventory management and distribution practices seek to minimize inventory holding periods by striving to take delivery of the inventory and manufacturing as close as possible to the sale or distribution of products to our customers. All of our businesses require various parts and raw materials, of which the availability and prices may fluctuate. Parts and raw materials commonly used in our products include motors, fabricated parts, castings, bearings, seals, nickel, copper, batteries, aluminum, plastics, PCBs and electronic components. While we may recover some cost increases through operational improvements, we are still exposed to some pricing risk, including increased pricing risk due to proposed duty and tariff assessments by the United States on foreign imports. We attempt to control costs through fixed-priced contracts with suppliers and various other programs, such as our global procurement initiative.

Our business relies on third-party suppliers, contract manufacturing and commodity markets to secure raw materials, parts and components used in our products. We typically acquire materials and components through a combination of blanket and scheduled purchase orders to support our materials requirements. For many of our products we have existing alternate sources of supply, or such sources are readily available.

We may experience price volatility or supply constraints for materials that are not available from multiple sources. From time to time, we acquire certain inventory in anticipation of supply constraints or enter into longer-term pricing commitments with vendors to improve the priority, price and availability of supply. There have been no raw material shortages in the past several years that have had a significant adverse impact on our business as a whole.

Our business segments experience a modest level of seasonality in their business. This seasonality is dependent on factors such as capital spending of customers as well as weather conditions, including heavy flooding, droughts, and fluctuations in temperatures, which can positively or negatively impact portions of our business.

Customers

Our business is not dependent on any single customer or a few customers the loss of which would have a material adverse effect on our Company. No individual customer accounted for more than 10% of our consolidated 2017 , 2016 or 2015 revenue.

Backlog

Backlog includes orders on hand as well as contractual customer agreements at the end of the period. Delivery schedules vary from customer to customer based on their requirements. Annual or multi-year contracts are subject to rescheduling and cancellation by customers due to the long-term nature of the contracts. As such, beginning total backlog, plus orders, minus revenues, will not equal ending total backlog due to contract adjustments, foreign currency fluctuations, and other factors. Typically, large projects require longer lead production cycles and deployment schedules and delays can occur from time to time. Total backlog was $1,513 million at December 31, 2017 and $1,292 million at December 31, 2016 . The December 31, 2016 backlog balance has been revised to include contractual agreements that Sensus has with customers that do not have minimum commitments but which we believe will be executed upon over the terms of the contracts. We anticipate that over 60% of the backlog at December 31, 2017 will be recognized as revenue during 2018 .

Research and Development

Research and development (“R&D”) is a key foundation of our growth strategy and we focus on the design and development of products and application know-how that anticipate customer needs and emerging trends. Our engineers are involved in new product development as well as improvement of existing products to increase customer value. Our businesses invest substantial resources into R&D. We anticipate we will continue to develop and invest in our R&D capabilities to promote a steady flow of innovative, high-quality and reliable products and applications to further strengthen our position in the markets we serve. We continue to increase our R&D investments as a percentage of revenue year over year, with 3.8% in 2017 when compared to 2.9% in 2016 and 2.6% in 2015.

We have R&D and product development capabilities around the world. R&D activities are initially conducted in our technology centers, located in conjunction with some of our major manufacturing facilities to ensure an efficient and robust development process. We have several global technical centers and local development teams around the world where we are supporting global needs and accelerating the customization of our products and solutions to local needs. In some cases, our R&D activities are conducted at our piloting and testing facilities and at strategic customer sites. These piloting and testing facilities enable us to serve our strategic markets globally.

Capitalized Software

We capitalize software developed for sale to external customers, which is included within "Other intangible assets, net" on our Consolidated Balance Sheets. As of December 31, 2017 and 2016 we had net capitalized software for sale to external customers of $89 million and $54 million, respectively.

Intellectual Property

We generally seek patent protection for those inventions and improvements that we believe will improve our competitive position. We believe that our patents and applications are important for maintaining the competitive differentiation of our products and improving our return on research and development investments. While we own, control or license a significant number of patents, trade secrets, proprietary information, trademarks, trade names, copyrights, and other intellectual property rights which, in the aggregate, are of material importance to our business, management believes that our business, as a whole, as well as each of our core business segments, is not materially dependent on any one intellectual property right or related group of such rights.

Patents, patent applications, and license agreements expire or terminate over time by operation of law, in accordance with their terms or otherwise. As the portfolio of our patents, patent applications, and license

agreements has evolved over time, we do not expect the expiration of any specific patent to have a material adverse effect on our financial position or results of operations.

Environmental Matters and Regulation

Our manufacturing operations worldwide are subject to many requirements under environmental laws. In the United States, the Environmental Protection Agency and similar state agencies administer laws and regulations concerning air emissions, water discharges, waste disposal, environmental remediation, and other aspects of environmental protection. Such environmental laws and regulations in the United States include, for example, the federal Clean Air Act, the Clean Water Act, the Resource, Conservation and Recovery Act, and the Comprehensive Environmental Response, Compensation and Liability Act. Environmental requirements significantly affect our operations. We have established an internal program to address compliance with applicable environmental requirements and, as a result, management believes that we are in substantial compliance with current environmental regulations.

While environmental laws and regulations are subject to change, such changes can be difficult to predict reliably and the timing of potential changes is uncertain. Management does not believe, based on current circumstances, that compliance costs pursuant to such regulations will have a material adverse effect on our financial position or results of operations. However, the effect of future legislative or regulatory changes could be material to our financial condition or results of operations.

Accruals for environmental matters are recorded on a site-by-site basis when it is probable that a liability has been incurred and the amount of the liability can be reasonably estimated, based on current law and existing technologies. It can be difficult to estimate reliably the final costs of investigation and remediation due to various factors. Our accrued liabilities for these environmental matters represent the best estimates related to the investigation and remediation of environmental media such as water, soil, soil vapor, air and structures, as well as related legal fees based upon the facts and circumstances as currently known to us. These estimates, and related accruals, are reviewed quarterly and updated for progress of investigation and remediation efforts and changes in facts and legal circumstances. Liabilities for these environmental expenditures are recorded on an undiscounted basis. We do not anticipate these liabilities will have a material adverse effect on our consolidated financial position or results of operations. At December 31, 2017 , we had estimated and accrued $4 million related to environmental matters.

Commitment to Sustainability

At Xylem, sustainability is at the very center of who we are and what we do. As a leading global water technology company, we deal with one of the world’s most urgent sustainability issues on a daily basis; responsible stewardship of our shared water resources. We believe that technology is a key link in how the world can solve water. We have a long history of innovation, but today, we’re focusing more than ever on the powerful capabilities of smart technology, integrated management and big data. These solutions will allow us to transport, treat, test and use water smarter, and more sustainably, than in the past. Our link to this enormous challenge informs how we think about sustainability and drives us to become a more sustainable company.

Employees

As of December 31, 2017 , Xylem had approximately 16,200 employees worldwide. We have approximately 5,400 employees in the United States, of whom approximately 16% are represented by labor unions. In certain foreign countries, our employees are represented by work councils. We believe that our facilities are in favorable labor markets with ready access to adequate numbers of workers and believe our relations with our employees are good.

ITEM 1A. RISK FACTORS

In evaluating our business, each of the following risks should be carefully considered, along with all of the other information in this Report and in our other filings with the SEC. Should any of these risks and uncertainties develop into actual events, our business, financial condition or results of operations could be materially and adversely affected.

Risks Related to Operational and External Factors

Failure to compete successfully in our markets could adversely affect our business.

We offer our products and services in competitive markets. We believe the principal points of competition in our markets are product performance, reliability and innovation, application expertise, brand reputation, energy efficiency, product life cycle cost, timeliness of delivery, proximity of service centers, effectiveness of our distribution channels and price. Maintaining and improving our competitive position will require successful management of these factors, including continued investment by us in manufacturing, research and development, engineering, marketing, customer service and support, and our distribution networks. Our future growth rate depends upon a number of factors, including our ability to (i) identify emerging technological trends in our target end-markets, (ii) develop and maintain competitive products and defend our market share against an ever-expanding number of competitors including many new and non-traditional competitors, (iii) enhance our products by adding innovative features that differentiate our products from those of our competitors and prevent commoditization of our products, (iv) develop, manufacture and bring compelling new products to market quickly and cost-effectively, and (v) attract, develop and retain individuals with the requisite technical expertise and understanding of customers’ needs to develop new technologies and introduce new products.

We may not be successful in maintaining our competitive position. Our competitors or third parties from outside of our industry may develop disruptive technologies or products that are superior to our products, or may develop more efficient or effective methods of providing products and services or may adapt more quickly than we do to new technologies or evolving customer requirements. The failure of our technologies or products to maintain and gain market acceptance due to more attractive offerings could significantly reduce our revenues and adversely affect our competitive standing and prospects. Pricing pressures also could cause us to adjust the prices of certain products to stay competitive, which could adversely affect our financial performance. Failure to continue competing successfully or to win large contracts could adversely affect our business, financial condition or results of operations.

Our results of operations and financial condition may be adversely affected by global economic and financial market conditions.

We compete around the world in various geographic and product markets. In 2017 , 46% , 26% and 21% of our total revenue was from customers located in the United States, western Europe and emerging markets, respectively. We expect revenue from these markets to be significant for the foreseeable future. Important factors impacting our businesses include the overall strength of these economies and our customers’ confidence in both local and global macro-economic conditions; industrial and federal, state, local and municipal governmental fiscal and trade policies; the strength of the residential and commercial real estate markets; interest rates; availability of commercial financing for our customers and end-users; the availability of funding for our public sector customers; and unemployment rates. A slowdown or prolonged downturn in our markets could have a material adverse effect on our business, financial condition and results of operations.

Economic and other risks associated with international sales and operations could adversely affect our business.

In 2017 , 54% of our total revenue was from customers outside the United States, with 21% of total revenue generated in emerging markets. We expect our sales from international operations and export sales to continue to be a significant portion of our revenue. We have placed a particular emphasis on increasing our growth and presence in emerging markets. Both our sales from international operations and export sales are subject, in varying degrees, to risks inherent to doing business outside the United States. These risks include the following:


•	changes in trade protection measures, including tariff and trade barriers and import and export licensing requirements;


•	potential negative consequences from changes to taxation policies;


•	unanticipated changes in other laws and regulations or in how such provisions are interpreted or administered;


•	potential disruptions in our global supply chain;


•	possibility of unfavorable circumstances arising from host country laws or regulations, including those related to infrastructure and data transmission and privacy;


•	currency exchange rate fluctuations and restrictions on currency repatriation;


•	disruption of operations from labor and political disturbances;


•	regional safety and security considerations;


•	increased costs and risks of developing, staffing and simultaneously managing a number of global operations as a result of distance as well as language and cultural differences; and


•	insurrection, armed conflict, terrorism or war.

Any payment of distributions, loans or advances to us by our foreign subsidiaries could be subject to restrictions on, or taxation of, dividends on repatriation of earnings under applicable local law, monetary transfer restrictions and foreign currency exchange regulations in the jurisdictions in which our subsidiaries operate. In addition to the general risks that we face outside the United States, our operations in emerging markets could involve additional uncertainties for us, including risks that governments may impose limitations on our ability to repatriate funds; governments may impose withholding or other taxes on remittances and other payments to us, or the amount of any such taxes may increase; an outbreak or escalation of any insurrection or armed conflict may occur; governments may seek to nationalize our assets; or governments may impose or increase investment barriers or other restrictions affecting our business. In addition, emerging markets pose other uncertainties, including the difficulty of enforcing agreements, challenges collecting receivables, protection of our intellectual property and other assets, pressure on the pricing of our products, higher business conduct risks, less qualified talent and risks of political instability. We cannot predict the impact such events might have on our business, financial condition and results of operations.

We may not achieve some or all of the expected benefits of our restructuring and transformation plans and our restructuring may adversely affect our business.

In recent fiscal years, we have initiated restructuring, realignment and transformation plans in an effort to optimize our cost structure and improve our operational efficiency and effectiveness. In 2017, we undertook steps to advance a multi-year effort to transform many of our support functions and related technologies, including Finance, Human Resources and Procurement. We may not be able to obtain the cost savings and benefits that were initially anticipated in connection with our restructuring and transformation plans. Additionally, as a result of these plans , we may experience a loss of continuity, loss of accumulated knowledge or inefficiency during transitional periods. Transformation, realignment and restructuring can require a significant amount of management and other employees' time and focus, which may divert attention from operating and growing our business.

The successful implementation and execution of our restructuring, realignment and transformation actions are critical to achieving our expected cost savings as well as effectively competing in the marketplace and positioning us for future growth. Factors that may impede a successful implementation include the retention of key employees, the impact of regulatory matters or matters involving certain third parties selected to assist us, and adverse economic market conditions. If our restructuring actions are not executed successfully, it could have a material adverse effect on our competitive position, business, financial condition and results of operations.

A material disruption to any of our facilities or operations may adversely affect our business .

If our facilities or operations were to be disrupted as a result of a significant equipment failure, natural disaster, power outage, fire, explosion, terrorism, cyber-based attack, labor disputes, work stoppages or slowdowns, adverse weather conditions or other reason, our financial performance could be adversely affected as a result of our inability to meet customer demand. Interruptions could increase our costs and reduce our sales. Any interruption in capability could require us to make substantial capital expenditures to remedy the situation, which could negatively affect our profitability and financial condition. Any recovery under our insurance policies may not offset the lost sales or increased costs that may be experienced during the disruption of operations, which could adversely affect our business, financial condition and results of operations.

Our business could be adversely affected by cyber threats or interruptions in information technology, communications networks and operations.

Our business operations rely on information technology and communications networks, and operations that are vulnerable to damage or disturbance from a variety of sources. Regardless of protection measures, essentially all systems are susceptible to disruption due to failure, vandalism, denial-of-service, insider risk, computer viruses, security breaches, natural disasters, power outages and other events. In addition, we have designed products and services that connect to and are part of the “Internet of Things.” While we attempt to provide adequate security measures to safeguard our products from cyber threats, the potential for an attack remains. A successful attack may result in inappropriate access to our or our customers' information or an inability for our products to function properly.

We, and some of our third party vendors, have experienced cybersecurity attacks in the past and may experience them in the future, likely with more frequency and involving a broader range of devices. To date, none have resulted in any material adverse impact to our business or operations. We have adopted measures designed to mitigate potential risks associated with information technology disruptions and cybersecurity threats, however, given the unpredictability of the timing, nature and scope of such disruptions, we could potentially be subject to production downtimes, operational delays, other detrimental impacts on our operations or ability to provide products and services to our customers, the compromising of confidential or otherwise protected information, destruction or corruption of data, security breaches, other manipulation or improper use of our systems or networks, financial losses from remedial actions, loss of business or potential liability, regulatory enforcement actions, and/or damage to our reputation, any of which could have a material adverse effect on our competitive position, results of operations, cash flows or financial condition. We also have or operate through a concentration of operations on certain sites, such as production and shared services centers, where business interruptions could cause material damage and costs. Transport of goods from suppliers, and to customers, could also be hampered for the reasons stated above.

Additionally, to conduct our operations, we regularly move data across national borders, and consequently are subject to a variety of continuously evolving and developing laws and regulations in the United States and abroad regarding privacy, data protection and data security. The scope of the laws that may be applicable to us is often uncertain and may be conflicting, particularly with respect to foreign laws. For example, the European Union’s General Data Protection Regulation (“GDPR”), which greatly increases the jurisdictional reach of European Union law and adds a broad array of requirements for handling personal data, including the public disclosure of significant data breaches, becomes effective in May 2018. And other countries have enacted or are enacting data localization laws that require data to stay within their borders. All of these evolving compliance and operational requirements impose significant costs that are likely to increase over time.

Although we continue to assess these risks, implement controls, and perform business continuity and disaster recovery planning, we cannot be sure that interruptions with material adverse effects will not occur.

Our strategy includes acquisitions, and we may not be able to make acquisitions of suitable candidates or integrate acquisitions successfully.

As part of our growth strategy, we plan to pursue the acquisition of other companies, assets and product lines that either complement or expand our existing business. We may not be able to identify suitable candidates successfully, negotiate appropriate acquisition terms, obtain financing that may be needed to consummate those acquisitions, complete proposed acquisitions, successfully integrate acquired businesses into our existing operations or expand into new markets. In addition, we cannot make assurances that any acquisition, once successfully integrated, will perform as planned, be accretive to earnings, or prove to be beneficial to our operations or cash flow.

Acquisitions involve a number of risks and present financial, managerial and operational challenges, including: diversion of management attention from existing businesses and operations; integration of technology, operations personnel, and financial and other systems; potentially insufficient internal controls over financial activities or financial reporting at an acquired entity that could impact us on a combined basis; the failure to realize expected synergies; the possibility that we become exposed to substantial undisclosed liabilities or new material risks associated with the acquired businesses; and the loss of key employees of the acquired businesses. Failure to successfully execute our acquisition strategy could adversely affect our business, financial condition or results of operations.

Failure to comply with laws, regulations and policies, including the U.S. Foreign Corrupt Practices Act or other applicable anti-corruption legislation could result in fines, criminal penalties and an adverse effect on our business.

We are subject to regulation under a wide variety of U.S. federal and state and non-U.S. laws, regulations and policies, including laws related to anti-corruption, trade regulations, including export and import compliance, anti-trust and money laundering, due to our global operations. The U.S. Foreign Corrupt Practices Act (the "FCPA"), the U.K. Bribery Act of 2010 and similar anti-bribery laws in other jurisdictions generally prohibit companies and their intermediaries from making improper payments to government officials or other persons for the purpose of obtaining or retaining business. Our policies mandate compliance with these anti-bribery laws. We operate in many parts of the world that are recognized as having governmental and commercial corruption and in certain circumstances, strict compliance with anti-bribery laws may conflict with local customs and practices. We cannot assure you that our internal control policies and procedures will always protect us from improper conduct of our employees or business partners. In the event that we believe or have reason to believe that our employees or business partners have or may have violated applicable laws, including anti-corruption laws, we may be required to investigate or have outside counsel investigate the relevant facts and circumstances, which can be expensive and require significant time and attention from senior management. Any such violation could result in substantial fines, sanctions, civil and/or criminal penalties, and curtailment of operations in certain jurisdictions, and might materially and adversely affect our business, results of operations or financial condition. In addition, actual or alleged violations could damage our reputation and ability to do business. Furthermore, detecting, investigating, and resolving actual or alleged violations is expensive and can consume significant time and attention of our senior management.

Our business could be adversely affected by significant movements in foreign currency exchange rates.

We conduct approximately 54% of our business in various locations outside the United States. We are exposed to fluctuations in foreign currency transaction exchange rates, particularly with respect to the Euro, Swedish Krona, Polish Zloty, Canadian Dollar, British Pound and Australian Dollar. Any significant change in the value of currencies of the countries in which we do business relative to the value of the U.S. Dollar or Euro could affect our ability to sell products competitively and control our cost structure, which could have a material adverse effect on our business, financial condition and results of operations. Additionally, we are subject to foreign exchange translation risk due to changes in the value of foreign currencies in relation to our reporting currency, the U.S. dollar. The translation risk is primarily concentrated in the exchange rate between the U.S. Dollar and the Euro, British Pound, Chinese Yuan, Canadian Dollar, Swedish Krona and Australian Dollar. As the U.S. Dollar fluctuates against other currencies in which we transact business, revenue and income can be impacted. For instance, our 2017 revenue increased by 0.9% due to favorable foreign currency impacts. Strengthening of the U.S. Dollar relative to the Euro and the currencies of the other countries in which we do business, could materially and adversely affect our sales growth in future periods. Refer to Item 7A "Quantitative and Qualitative Disclosures about Market Risk" for additional information on foreign exchange risk.

Failure to retain our existing senior management, engineering, sales and other key personnel or the inability to attract and retain new qualified personnel could negatively impact our ability to operate or grow our business.

Our success will continue to depend to a significant extent on our ability to retain or attract a significant number of employees in senior management, engineering, sales and other key personnel. The ability to attract or retain employees will depend on our ability to offer competitive compensation, training and cultural benefits. We will need to continue to develop a roster of qualified talent to support business growth and replace departing employees. Effective succession planning is also important to our long-term success. Failure to ensure effective transfer of knowledge and smooth transitions involving key employees could hinder our strategic planning and execution. A failure to retain or attract highly skilled personnel could adversely affect our operating results or ability to operate or grow our business.

Product defects and unanticipated use or inadequate disclosure with respect to our products could adversely affect our business, reputation and financial statements.

Manufacturing or design defects in (including in products or components that we source from third parties), unanticipated use of, or inadequate disclosure of risks relating to the use of our products could create product safety, regulatory or environmental risks, including personal injury, death or property damage. These events could lead to recalls or safety alerts relating to our products, result in the removal of a product from the market and result in product liability claims being brought against us. Although we have liability insurance, we cannot be certain that

this insurance coverage will continue to be available to us at a reasonable cost or will be adequate to cover any product liability claims. Manufacturing, design, software or service defects or inadequacies may also result in contractual damages or credits being issued, which could impact our revenue. Recalls, removals and product liability and quality claims can result in significant costs, as well as negative publicity and damage to our reputation that could reduce demand for our products and have a material adverse effect on our business, financial condition and results of operations.

Weather conditions and climate changes may adversely affect, or cause volatility in, our financial results.

Weather conditions, including heavy flooding, droughts and fluctuations in temperatures or weather patterns, including as a result of climate change, can positively or negatively impact portions of our business. Within the dewatering space, pumps provided through our Godwin and Flygt brands are used to remove excess or unwanted water. Heavy flooding due to weather conditions drives increased demand for these applications. On the other hand, drought conditions drive higher demand for pumps used in agricultural and turf irrigation applications, such as those provided by our Goulds Water Technology and Lowara brands. Fluctuations to warmer and cooler temperatures result in varying levels of demand for products used in residential and commercial applications where homes and buildings are heated and cooled with HVAC units such as those provided by our B&G brand. Given the unpredictable nature of weather conditions and climate change, this may result in volatility for certain portions of our business, as well as the operations of certain of our customers and suppliers.

Our financial results can be difficult to predict.

Our business is impacted by a substantial amount of short cycle, and book-and-bill business, which we have limited insight into, particularly for the business that we transact through our distributors. We are also impacted by large projects, whose timing can change based upon customer requirements due to a number of factors affecting the project, such as funding, readiness of the project and regulatory approvals. Accordingly, our financial results for any given period can be difficult to predict.

Changes in our effective tax rates may adversely affect our financial results.

We sell our products in approximately 150 countries and 54% of our revenue was generated outside the United States in 2017 . Given the global nature of our business, a number of factors may increase our future effective tax rates, including:


•	the jurisdictions in which profits are determined to be earned and taxed;


•	sustainability of historical income tax rates in the jurisdictions in which we conduct business;


•	the resolution of issues arising from tax audits with various tax authorities; and


•	changes in the valuation of our deferred tax assets and liabilities, and changes in deferred tax valuation allowances.

For example, compliance with the 2017 United States Tax Cut and Jobs Act (“Tax Act”) may require the collection of information not regularly produced within our Company, the use of provisional estimates in our financial statements, and the exercise of significant judgment in accounting for its provisions. Many aspects of the Tax Act are unclear and may not be clarified for some time. As regulations and guidance evolve with respect to the Tax Act, and as we gather more information and perform more analysis, our results may differ from previous estimates and may materially affect our financial position. Our non-U.S. operations will be subject to alternative tax regimes implemented under the Tax Act. Any significant increase in our future effective tax rates could reduce net income for future periods.

Our business could be adversely affected by inflation and other manufacturing and operating cost increases.

Our operating costs are subject to fluctuations, particularly due to changes in commodity prices, raw materials, energy and related utilities, freight, and cost of labor. In order to remain competitive, we may not be able to recuperate all or a portion of these higher costs from our customers through product price increases. Further, in a declining price environment, our operating margins may contract because we account for inventory using the first-in, first- out method. Actions we take to mitigate volatility in manufacturing and operating costs may not be successful and, as a result, our business, financial condition and results of operation could be materially and adversely affected.

Our business could be adversely affected by the inability of suppliers to meet delivery requirements.

Our business relies on third-party suppliers, contract manufacturing and commodity markets to secure raw materials, parts and components used in our products, and we expect that reliance to increase. Parts and raw materials commonly used in our products include motors, fabricated parts, castings, bearings, seals, nickel, copper,

batteries, aluminum, and plastics. We are exposed to the availability of these materials, which may be subject to curtailment or change due to, among other things, interruptions in production by suppliers, labor disputes, the impaired financial condition of a particular supplier, suppliers’ allocations to other purchasers, changes in tariff regimes, exchange rates and prevailing price levels, ability to meet regulatory requirements, weather emergencies or acts of war or terrorism. Any delay in our suppliers’ abilities to provide us with necessary materials could impair our ability to deliver products to our customers and, accordingly, could have a material adverse effect on our business, financial condition or results of operations.

Our indebtedness may affect our business and may restrict our operational flexibility.

As of December 31, 2017 , our total outstanding indebtedness was $2,200 million as described under “Liquidity and Capital Resources." Our indebtedness could:


•	increase our vulnerability to general adverse economic and industry conditions;


•	limit our ability to obtain additional financing or borrow additional funds;


•	limit our ability to pay future dividends;


•	limit our flexibility in planning for, or reacting to, changes in our business and the industry in which we operate;


•	require that a substantial portion of our cash flow from operations be used for the payment of interest on our indebtedness instead of funding working capital, capital expenditures, acquisitions or other general corporate purposes; and


•	increase the amount of interest expense that we must pay because some of our borrowings are at variable interest rates, which, as interest rates increase, would result in higher interest expense.

In addition, there can be no assurance that future borrowings or equity financing will be available to us on favorable terms or at all for the payment or refinancing of our indebtedness. If we incur additional debt or raise equity through the issuance of preferred stock, the terms of the debt or preferred stock issued may give the holders rights, preferences and privileges senior to those of holders of our common stock, particularly in the event of liquidation. The terms of the debt may also impose additional and more stringent restrictions on our operations than we currently have.

Our ability to make scheduled principal payments of, to pay interest on, or to refinance our indebtedness and to satisfy our other debt obligations will depend on our future operating performance, which may be affected by factors beyond our control. If we are unable to service our indebtedness, our business, financial condition and results of operations would be materially adversely affected.

We may be negatively impacted by litigation and regulatory proceedings.

We are subject to various laws, ordinances, regulations and other requirements of government authorities in foreign countries and in the United States, any violation of which could potentially create substantial liability for us and also damage to our reputation. Changes in laws, ordinances, regulations or other government policies, the nature, timing, and effect of which are uncertain, may significantly increase our expenses and liabilities.

From time to time we are involved in legal proceedings that are incidental to the operation of our businesses. These proceedings may seek remedies relating to environmental matters, acquisitions or divestitures, product liability and personal injury claims, privacy, employment, labor and pension matters, and government contract issues and commercial or contractual disputes. Our acquisition of Sensus and technology focused companies has increased our exposure to intellectual property litigation and we expect that this risk will continue to increase as we execute on our innovation and technology priorities.

It is not possible to predict with certainty the outcome of claims, investigations, and lawsuits, and we could in the future incur judgments, fines or penalties or enter into settlements of lawsuits and claims that could have an adverse effect on our business, results of operations and financial condition in any particular period. Additionally, we may be required to change or cease operations at one or more facilities if a regulatory agency determines that we have failed to comply with laws, regulations or orders applicable to our business.

The global and diverse nature of our operations, coupled with the increase in regulation and enforcement in many regions of the globe, means that legal and compliance risks will continue to exist and additional legal proceedings and other contingencies, the outcome of which cannot be predicted with certainty, will arise from time to time. In addition, subsequent developments in legal proceedings may affect our assessments and estimates of loss

contingencies recorded as a reserve and require us to make payments in excess of our reserves, which could have an adverse effect on our results of operations and financial condition.

If we do not or cannot adequately protect our intellectual property, if third parties infringe our intellectual property rights, or if third parties claim that we are infringing or misappropriating their intellectual property rights, we may suffer competitive injury, expend significant resources enforcing our rights or defending against such claims, or be prevented from selling products or services.

We own numerous patents, trademarks, copyrights, trade secrets and other intellectual property and licenses to intellectual property owned by others, which in aggregate are important to our business. The intellectual property rights that we obtain, however, may not provide us with a significant competitive advantage because they may not be sufficiently broad or may be challenged, invalidated, circumvented, independently developed, or designed-around, particularly in countries where intellectual property rights laws are not highly developed, protected or enforced. Our failure to obtain or maintain intellectual property rights that convey competitive advantage, adequately protect our intellectual property or detect or prevent circumvention or unauthorized use of such property and the cost of enforcing our intellectual property rights could adversely impact our business, financial condition and results of operations.

From time to time, we receive notices from third parties alleging intellectual property infringement or misappropriation. Any dispute or litigation regarding intellectual property could be costly and time-consuming due to the complexity and the uncertainty of intellectual property litigation. Our intellectual property portfolio may not be useful in asserting a counterclaim, or negotiating a license, in response to a claim of infringement or misappropriation. In addition, as a result of such claims of infringement or misappropriation, we could lose our rights to critical technology, be unable to license critical technology or sell critical products and services, be required to pay substantial damages or license fees with respect to the infringed rights or be required to redesign our products at substantial cost, any of which could adversely impact our competitive position, financial condition and results of operations. Even if we successfully defend against claims of infringement or misappropriation, we may incur significant costs and diversion of management attention and resources, which could adversely affect our business, financial condition and results of operations.

A significant portion of our products and offerings in our Measurement & Control Solutions segment are affected by the availability and regulation of radio spectrum and could be affected by interference with the radio spectrum that we use.

A significant portion of the offering in our Measurement & Control Solutions segment use radio spectrum, which is subject to government regulation. To the extent we introduce new products designed for use in the United States or another country into a new market, such products may require significant modification or redesign in order to meet frequency requirements and other regulatory specifications. In some countries, limitations on frequency availability or the cost of making necessary modifications may preclude us from selling our products in those countries. The regulations that govern our use of the radio spectrum may change and the changes may require us to modify our products or seen new partnerships, either directly or due to interference caused by new consumer products allowed under the regulations. The inability to modify our products to meet such requirements, the possible delays in completing such modifications, and the cost of such modifications all could have a material adverse effect on our business, financial condition, and results of operations. In addition, suitable partners for co-development may not be able to be secured by us.

In the United States, our products are primarily designed to use licensed spectrum in the 900MHz range. If the Federal Communications Commission (“FCC”) did not renew our existing spectrum licenses, our business could be adversely affected. In addition, there may be insufficient available frequencies in some markets to sustain or develop our planned operations at a commercially feasible price or at all.

Outside of the United States, certain of our products require the use of radio frequency and are subject to regulations. In some jurisdictions, radio station licenses may be granted for a fixed term and must be periodically renewed. Our advanced and smart metering systems offering typically transmit to (and receive information from, if applicable) handheld, mobile, or fixed network reading devices in licensed bands made available to us through strategic partnerships and are reliant to some extent on the licensed spectrum continuing to be available through our partners or our customers. We may be unable to find partners or customers that have access to sufficient frequencies in some markets to sustain or develop our planned operations or to find partners or customers that have access to sufficient frequencies in the relevant markets at a commercially feasible price or at all.

We may incur impairment charges for our goodwill and other indefinite-lived intangible assets which would negatively impact our operating results.

We have a significant amount of goodwill and purchased intangible assets on our balance sheet as a result of acquisitions we have completed. As of December 31, 2017 , the net carrying value of our goodwill and other indefinite-lived intangible assets totaled approximately $ 3 billion . The carrying value of goodwill represents the fair value of an acquired business in excess of identifiable assets and liabilities as of the acquisition date. The carrying value of indefinite-lived intangible assets represents the fair value of trademarks, trade names and FCC licenses as of the acquisition date. We do not amortize goodwill and indefinite-lived intangible assets that we expect to contribute indefinitely to our cash flows, but instead we evaluate these assets for impairment at least annually, or more frequently if interim indicators suggest that a potential impairment could exist. In testing for impairment, we will make a qualitative assessment, and if we believe that it is more likely than not that the fair value of a reporting unit is less than its carrying amount, a goodwill impairment test is required. Significant negative industry or economic trends, disruptions to our business, inability to effectively integrate acquired businesses, unexpected significant changes or planned changes in use of the assets, divestitures and market capitalization declines may impair our goodwill and other indefinite-lived intangible assets. Any charges relating to such impairments could adversely affect our results of operations and financial condition.

We cannot make assurances that we will pay dividends on our common stock or continue to repurchase our common stock under Board approved share repurchase plans, and likewise our indebtedness could limit our ability to pay dividends or make share repurchases.

The timing, declaration, amount and payment of future dividends to our shareholders fall within the discretion of our Board of Directors and will depend on many factors, including our financial condition, results of operations and capital requirements, as well as applicable law, regulatory constraints, industry practice and other business considerations that our Board of Directors considers relevant. There can be no assurance that we will pay a dividend in the future or continue to pay dividends.

Further, the timing and amount of the repurchase of our common stock under Board approved share repurchase plans has similar dependencies as the payment of dividends and accordingly, there can be no assurances that we will repurchase our common stock.

Additionally, if we cannot generate sufficient cash flow from operations to meet our debt payment obligations, then our ability to pay dividends, if so determined by the Board of Directors, or make share repurchases will be impaired and we may be required to attempt to restructure or refinance our debt, raise additional capital or take other actions such as selling assets, reducing or delaying capital expenditures, reducing our dividend or delaying or curtailing share repurchases. There can be no assurance, however, that any such actions could be effected on satisfactory terms, if at all, or would be permitted by the terms of our debt or our other credit and contractual arrangements.

Unforeseen environmental issues could impact our financial position or results of operations.

Our operations and products and offerings are subject to and affected by many federal, state, local and foreign environmental laws and regulations. In addition, we could be affected by future environmental laws or regulations, including, for example, those imposed in response to climate change concerns. Compliance with current and future environmental laws and regulations currently requires and is expected to continue to require operating and capital expenditures.

Environmental laws and regulations may authorize substantial fines and criminal sanctions as well as facility shutdowns to address violations, and may require the installation of costly pollution control equipment or operational changes to limit emissions or discharges. We also incur, and expect to continue to incur, costs to comply with current environmental laws and regulations.

Developments such as the adoption of new environmental laws and regulations, stricter enforcement of existing laws and regulations, violations by us of such laws and regulations, discovery of previously unknown or more extensive contamination, litigation involving environmental impacts, our inability to recover costs associated with any such developments, or financial insolvency of other responsible parties could in the future have a material adverse effect on our financial position and results of operations.

The level of returns on postretirement benefit plan assets, changes in interest rates and other factors could affect our earnings and cash flows in future periods.

Certain members of our current and retired employee population are covered by pension and other employee-related defined benefit plans (collectively, postretirement benefit plans). We may experience significant fluctuations in costs related to our postretirement benefit plans as a result of macro-economic factors, such as interest rates,

that are beyond our control. The cost of our postretirement plans is incurred over long periods of time and involves factors and uncertainties during those periods which can be volatile and unpredictable, including rates of return on postretirement benefit plan assets, discount rates used to calculate liabilities and expenses and rates of future compensation increases. Management develops each assumption using relevant plan and Company experience and expectations in conjunction with market-related data. Our liquidity, financial position (including shareholders’ equity) and results of operations could be materially affected by significant changes in key economic indicators, actuarial experience, financial market volatility, future legislation and other governmental regulatory actions.

We make contributions to fund our postretirement benefit plans when considered necessary or advantageous to do so. The macro-economic factors discussed above, including the return on postretirement benefit plan assets and the minimum funding requirements established by local government funding or taxing authorities, or established by other agreement, may influence future funding requirements. A significant decline in the fair value of our plan assets, or other adverse changes to our overall pension and other employee-related benefit plans, could require us to make significant funding contributions and affect cash flows in future periods.

The market price of our common stock may fluctuate significantly.

We cannot predict the prices at which our common stock may trade. The market price of our common stock may fluctuate widely, depending on many factors, some of which may be beyond our control, including:


•	actual or anticipated fluctuations in our operating results due to factors related to our business;


•	success or failure of our business strategy;


•	our quarterly or annual earnings, or those of other companies in our industry;


•	our ability to obtain financing as needed;


•	stock repurchases;


•	acquisitions and divestitures;


•	announcements by us or our competitors of significant new business awards;


•	announcements by us or our competitors of significant acquisitions or dispositions;


•	changes in accounting standards, policies, guidance, interpretations or principles;


•	changes in earnings estimates by securities analysts or our ability to meet those estimates;


•	our ability to execute transformation, restructuring and realignment actions;


•	the operating and stock price performance of other comparable companies;


•	natural or environmental disasters that investors believe may affect us;


•	overall market fluctuations;


•	fluctuations in the budgets of federal, state and local governmental entities around the world;


•	results from any material litigation or government investigation;


•	changes in laws and regulations affecting our business; and


•	general economic conditions and other external factors.

Stock markets in general have experienced volatility that has often been unrelated to the operating performance of a particular company. These broad market fluctuations could adversely affect the trading price of our common stock.

Anti-takeover provisions in our organizational documents and Indiana law could delay or prevent a change in control.

Certain provisions of our third amended and restated articles of incorporation and our amended and restated by-laws may delay or prevent a merger or acquisition of part or all of our business operations. For example, our articles of incorporation and our by-laws, among other things, require advance notice for shareholder proposals and nominations. In addition, our articles of incorporation authorize our Board of Directors to issue one or more series of preferred stock. These provisions may also discourage acquisition proposals of our business operations or delay or prevent a change in control, which could harm our stock price. Indiana law also imposes some restrictions on mergers and other business combinations between any holder of 10% or more of our outstanding common stock and us.

In connection with our Spin-off, ITT (now ITT LLC) and Exelis, acquired by Harris Inc., will indemnify us for certain liabilities and we will indemnify ITT (now ITT LLC) or Exelis for certain liabilities. If we are required to indemnify ITT (now ITT LLC) or Exelis, we may need to divert cash to meet those obligations and our financial results could be negatively impacted. In the case of ITT's or Exelis's indemnity, there can be no assurance that those indemnities will be sufficient to insure us against the full amount of such liabilities, or as to ITT's or Exelis's ability to satisfy its indemnification obligations in the future.

Pursuant to the Distribution Agreement and certain other agreements with ITT (now ITT LLC) and Exelis, ITT (now ITT LLC) and Exelis agreed to indemnify us from certain liabilities, and we agreed to indemnify ITT (now ITT LLC) and Exelis for certain liabilities. Indemnities that we may be required to provide ITT (now ITT LLC) and Exelis may be significant and could negatively impact our business. Third parties could also seek to hold us responsible for any of the liabilities that ITT (now ITT LLC) or Exelis has agreed to retain. Further, there can be no assurance that the indemnities from ITT (now ITT LLC) and Exelis will be sufficient to protect us against the full amount of such liabilities, or that ITT (now ITT LLC) and Exelis will be able to fully satisfy their indemnification obligations. Moreover, even if we ultimately were to succeed in recovering from ITT (now ITT LLC) and Exelis any amounts for which we are held liable, we may be temporarily required to bear these losses ourselves. Each of these risks could negatively affect our business, results of operations and financial condition.

ITEM 7. MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS

The following discussion should be read in conjunction with our consolidated financial statements and the notes thereto. This discussion summarizes the significant factors affecting our results of operations and the financial condition of our business during each of the fiscal years in the three-year period ended December 31, 2017 . Except as otherwise indicated or unless the context otherwise requires, “Xylem,” “we,” “us,” “our” and “the Company” refer to Xylem Inc. and its subsidiaries.

Overview

Xylem is a leading global water technology company. We design, manufacture and service highly engineered solutions ranging across a wide variety of critical applications. Our broad portfolio of solutions addresses customer needs across the water cycle, from the delivery, measurement and use of drinking water to the collection, test and treatment of wastewater to the return of water to the environment. Our product and service offerings are organized into three reportable segments that are aligned around the critical market applications they provide: Water Infrastructure, Applied Water and Measurement & Control Solutions (formerly Sensus & Analytics).

As previously announced, in the second quarter of 2017 we implemented an organizational redesign by moving Xylem’s Analytics business from our Water Infrastructure segment to combine it with our Sensus and Visenti businesses, which were acquired in the fourth quarter of 2016, to form Measurement & Control Solutions. We believe that the combination of these businesses will enhance our focus on advanced sensing technologies and will lead to operating efficiencies by integrating the supply chain process and moving to a leaner functional structure. Accordingly, our reportable segments have changed. Beginning with the second quarter of 2017, the Company now reports the financial position and results of operations of its Analytics, Sensus and Visenti businesses as one new reportable segment, which is called Measurement & Control Solutions. Our Water Infrastructure reportable segment no longer includes the results of our Analytics business. The Company has recast certain historical amounts between the Company's Water Infrastructure and Measurement & Control Solutions reportable segments, however this change had no impact on the Company's historical consolidated financial position or results of operations. The recast financial information does not represent a restatement of previously issued financial statements. Our Applied Water reportable segment remains unchanged.

•

Water Infrastructure serves the water infrastructure sector with pump systems that transport water from aquifers, lakes, rivers and seas; with filtration, ultraviolet and ozone systems that provide treatment, making the water fit to use; and pumping solutions that move the wastewater to treatment facilities where our mixers, biological treatment, monitoring and control systems provide the primary functions in the treatment process. We also provide sales and rental of specialty dewatering pumps and related equipment and services. In the Water Infrastructure segment, we provide the majority of our sales directly to customers with strong applications expertise, while the remaining amount is through distribution partners.

•

Applied Water serves the usage applications sector with water pressure boosting systems for heating, ventilation and air conditioning and for fire protection systems to the residential and commercial building services markets. In addition, our pumps, heat exchangers, and controls provide cooling to power plants and manufacturing facilities, as well as circulation for food and beverage processing. We also provide boosting systems for farming irrigation and pumps for dairy operations. In the Applied Water segment, we provide the majority of our sales through long-standing relationships with many of the leading independent distributors in the markets we serve, with the remainder going directly to customers.

•

Measurement & Control Solutions primarily serves the utility infrastructure solutions and services sector by delivering communications, smart metering, measurement and control technologies and services that allow customers to more effectively use their distribution networks for the delivery of critical resources such as water, electricity and natural gas. In the Measurement & Control Solutions segment, we also provide analytical instrumentation used to measure water quality, flow and level in wastewater, surface water and coastal environments. Additionally, we sell software and services including cloud-based analytics, remote monitoring and data management, leak detection and pressure monitoring solutions. We also sell smart lighting products and solutions that improve efficiency and public safety efforts across communities. In the Measurement & Control Solutions segment, we generate our sales through a combination of long-standing relationships with leading distributors and dedicated channel partners as well as direct sales depending on the regional availability of distribution channels and the type of product.

Key Performance Indicators and Non-GAAP Measures

Management reviews key performance indicators including revenue, gross margins, segment operating income and margins, orders growth, working capital and backlog, among others. In addition, we consider certain non-GAAP (or "adjusted") measures to be useful to management and investors evaluating our operating performance for the periods presented, and provide a tool for evaluating our ongoing operations, liquidity and management of assets. This information can assist investors in assessing our financial performance and measures our ability to generate capital for deployment among competing strategic alternatives and initiatives, including, but not limited to, dividends, acquisitions, share repurchases and debt repayment. Excluding revenue, Xylem provides guidance only on a non-GAAP basis due to the inherent difficulty in forecasting certain amounts that would be included in GAAP earnings, such as discrete tax items, without unreasonable effort. These adjusted metrics are consistent with how management views our business and are used to make financial, operating and planning decisions. These metrics, however, are not measures of financial performance under GAAP and should not be considered a substitute for revenue, operating income, net income, earnings per share (basic and diluted) or net cash from operating activities as determined in accordance with GAAP. We consider the following non-GAAP measures, which may not be comparable to similarly titled measures reported by other companies, to be key performance indicators:

•

"organic revenue" and "organic orders" defined as revenue and orders, respectively, excluding the impact of fluctuations in foreign currency translation and contributions from acquisitions and divestitures. Divestitures include sales of insignificant portions of our business that did not meet the criteria for classification as a discontinued operation. The period-over-period change resulting from foreign currency translation impacts is determined by translating current period and prior period activity using the same currency conversion rate.


•	"constant currency" defined as financial results adjusted for foreign currency translation impacts by translating current period and prior period activity using the same currency conversion rate. This approach is used for countries whose functional currency is not the U.S. dollar.

•

"adjusted operating income", "adjusted segment operating Income", "adjusted net income" and “adjusted EPS” defined as operating income, segment operating income, net income and earnings per share, adjusted to exclude restructuring and realignment costs, Sensus acquisition related costs, gain or loss from sale of businesses, special charges and tax-related special items, as applicable. A reconciliation of adjusted net income is provided below.



(in millions, except per share data)	2017		2016		2015
Net income attributable to Xylem	$	331	$	260	$	340
Restructuring and realignment, net of tax of $13, $13 and $5, respectively	28		34		15
Sensus acquisition related costs, net of tax of $8 and $15, respectively	14		38		—
Special charges, net of tax of $4, $7 and $0, respectively	8		11		5
Tax-related special items	40		21		(15		)
Loss (gain) from sale of businesses, net of tax benefit of $2 and net of tax of $0, respectively	12		—		(9		)
Adjusted net income	$	433	$	364	$	336
Weighted average number of shares diluted	180.9		180.0		181.7
Earnings per share - diluted	$	1.83	$	1.45	$	1.87
Adjusted earnings per share	$	2.40	$	2.03	$	1.85

Executive Summary

Xylem reported revenue of $4,707 million for 2017 , an increase of $936 million or 24.8% from $3,771 million reported in 2016 . Revenue increased 23.9% on a constant currency basis mostly due to $790 million of revenue related to acquisitions and organic revenue growth of $122 million driven by growth in all end markets.

Operating income for 2017 was $556 million , reflecting an increase of $150 million or 36.9% compared to $406 million in 2016 . Operating margin was 11.8% for 2017 versus 10.8% for 2016, an increase of 100 basis points. The increase in operating margin was primarily due to cost reductions resulting from progress in our global procurement and productivity initiatives, a decrease in Sensus acquisition related costs, restructuring savings and a decrease in restructuring and realignment charges. These favorable impacts on operating margin were partially offset by cost inflation increases, Sensus purchase accounting impacts and an increase in special charges.

Adjusted operating income was $630 million, with an adjusted operating margin of 13.4% in 2017 as compared to adjusted operating income of $511 million with an adjusted operating margin of 13.6% in 2016. The decrease in adjusted operating margin was mostly due to cost inflation increases, increased spending on strategic investments and Sensus purchase accounting impacts, which were largely offset by cost savings from our global procurement and productivity initiatives and restructuring savings. The non-cash Sensus purchase accounting impact on adjusted operating margin for the year was 50 basis points, which if excluded would bring the adjusted operating margin to 13.9%, a 30 basis point increase over the prior year.

Additional financial highlights for 2017 include the following:


•	Net income attributable to Xylem of $331 million , or $1.83 per diluted share ($433 million or $2.40 per diluted share on an adjusted basis, up 19% from 2016)


•	Cash from operating activities of $686 million , and free cash flow, excluding Sensus acquisition related costs, of $544 million up 40.9% from 2016.


•	Orders of $ 4,868 million , up 27.3% from $ 3,824 million in 2016 (up 6.8% on an organic basis)


•	Dividends paid to shareholders increased 16% in 2017 .

2018 Business Outlook

We anticipate total revenue growth in the range of 8% to 10% in 2018, with the recently announced acquisition of Pure Technologies contributing approximately 2% of that growth. Organic revenue growth is anticipated to be 4% to 6%. The following is a summary of our 2017 organic revenue performance and 2018 organic revenue outlook by end market.

•

Public utilities increased approximately 3% for 2017 on an organic basis driven by growth in the United States and Asia Pacific. For 2018, we expect organic growth in the mid-single-digit range driven by solid growth in the U.S. from water and wastewater spending and stable low-single-digit growth in Europe. Additionally, we expect high-single-digit growth from the smart meter market. A healthy infrastructure investment focus in the emerging markets will continue broadly in China and India.

•

Industrial increased by roughly 2% for 2017 on an organic basis driven by growth in the emerging markets, specifically in China and Latin America, and a recovery in global oil and gas and mining markets. For 2018, we expect organic growth in the low to mid-single-digits. We believe that market conditions in the U.S. and Europe will continue to improve modestly and oil and gas and mining markets will continue to stabilize in North America. We expect conditions in the emerging markets to be mixed as strength in China and India will be offset by softening conditions in the Middle East and Latin America.

•

In the commercial markets, organic growth was around 5% for 2017 primarily driven by strength in the United States. For 2018, we expect continued organic growth in the low to mid-single-digit range. The U.S. market is expected to see low, stable growth while growth in Europe is expected to moderate after strong performance. Strength in the emerging markets will be driven by initiatives in India, the building market in China and large project wins in the Middle East from product localization.

•

In residential markets, organic growth increased by about 12% in 2017 primarily driven by strength in Asia Pacific and the United States. For 2018, we expect mid-single-digit growth primarily driven by solid mid-single-digit growth in the U.S. market. Market share gains from an increased selling focus in Europe, along with an increased demand in China and other Asia Pacific countries for a secondary clean water source, are also expected to contribute to this growth.

We will continue to strategically execute restructuring and realignment actions primarily to reposition our European and North American businesses in an effort to optimize our cost structure and improve our operational efficiency and effectiveness. During 2017, we incurred $20 million and $21 million in restructuring and realignment costs, respectively. As a result of these actions in 2017, we realized $6 million of net savings and expect to realize approximately $10 million of incremental net savings in 2018. We expect additional incremental savings to be realized in 2019 and beyond as we complete these actions. During 2018, we currently expect to incur approximately $35 million in restructuring, realignment and integration costs.

We plan to continue to take actions and focus spending in 2018 on actions that allow us to make progress on our top strategic priorities. The priority of accelerating profitable growth encompass our initiatives to drive commercial excellence, grow in emerging markets and strengthen innovation and technology through creation of new centers of excellence, a streamlined approach to product development and smart acquisitions. The priority of driving continuous improvement is an area where we will continue to work to create new opportunities to unlock savings by eliminating waste and increasing efficiencies, which is supported by efforts to expand and further deepen our talent pool. We plan to continue to deploy capital in smart, disciplined ways to develop and acquire solutions to address our customers’ challenges. Finally, we continue to work to improve cash performance and generate capital to return to our shareholders.

2017 versus 2016

Revenue

Revenue generated for 2017 was $4,707 million , an increase of $936 million , or 24.8% , compared to $3,771 million in 2016 . On a constant currency basis, revenue grew 23.9% . This increase in revenue was primarily driven by additional revenue of $790 million from acquisitions. There was also strong organic growth of $122 million during the year, driven primarily by North America as well as strength in the emerging markets, particularly in China and India. Additionally, to a lesser extent, Europe contributed to this organic growth despite ongoing weakness in the United Kingdom during the year.

The following table illustrates the impact on 2017 revenue from organic growth, recent acquisitions and divestitures, and foreign currency translation in relation to revenue.

(a)	Foreign currency translation impact primarily due to strength in the value of the Euro, Canadian dollar, Russian Ruble, Australian dollar, South African Rand and various other currencies, partially offset by weakness in the British Pound against the U.S. Dollar.

Water Infrastructure

Water Infrastructure’s revenue increased $72 million , or 3.7% , in 2017 (2.9% increase on a constant currency basis) compared to 2016 . Revenue benefited from $16 million of foreign currency translation for the year and included organic growth of $56 million , or 2.9% .

Organic growth for the year was driven by strength in the industrial end market, and to a lesser extent in the public utility end market. The growth in both of these end markets was driven by strength from Asia Pacific and North America.

From an application perspective, organic revenue growth was driven primarily by our transport application. The transport application grew in the industrial end market due to strength in the dewatering business which benefited from the recovery of the industrial construction market, particularly within the distribution channel and recovery of oil and gas and mining markets in North America and Latin America. The transport application also grew in the public utility end market driven by increased municipal spending in North America and increased projects in the Middle East and India. Organic revenue from our treatment application also contributed to the segment's growth primarily from growth in China from industrial treatment project deliveries as well as growth in Europe from municipal treatment projects.

Applied Water

Applied Water’s revenue increased $28 million , or 2.0% , in 2017 ( 1.7% increase on a constant currency basis) compared to 2016. Revenue benefited from $4 million of foreign currency translation for the year and the constant currency increase included organic growth of $34 million , or 2.4% .

Organic growth for the year was driven by strength in the residential and commercial end markets in the United States, Asia Pacific and western Europe, which were partially offset by declines in the industrial market.

From an application perspective, growth in residential building services was primarily driven by strength in the United States, where we benefited from the timing of promotions and market share gains, and continued strength in Asia Pacific. Commercial building services also grew, primarily in North America, western Europe and Asia Pacific, driven by new product traction and sales channel investments. This growth was partially offset by a decline in industrial applications, primarily driven by unfavorable weather conditions impacting the agriculture business in the United States, partially offset by strength in western Europe.

Measurement & Control Solutions

Measurement & Control Solutions revenue increased $836 million, or 187.4%, in 2017 (184.3% on a constant currency basis) compared to 2016. The revenue increase for the year was almost entirely from $790 million of revenue related to acquisitions that we did not have in the prior year. Most of the additional revenue contributed by the Sensus business was generated in the United States with additional revenue coming primarily from western Europe and China. The majority of the Sensus business revenue came from water applications with gas and electric applications making up most of the remaining sales for the year. Organic revenue growth in the Measurement & Control Solutions segment was $32 million, or 7.2%, for the year. Organic growth was driven primarily by growth across all applications, except electric which had slight declines. Much of the organic revenue increase was in the water application, which had increased AMI deployments in North America as well as higher demand for iPerl product in eastern Europe and the Middle East. Organic revenue also increased in the gas application, primarily due to AMI deployments in North America, as well as in the software and services application, primarily driven by a couple of major contract upgrades. The test application also contributed to the increase in organic revenue as a result of strength from the environmental monitoring business in the United States.

Orders/Backlog

Orders received during 2017 increased by $1,044 million , or 27.3% , to $ 4,868 million ( 26.4% increase on a constant currency basis). The order growth on a constant currency basis was primarily driven by additional orders from recent acquisitions, primarily Sensus, of $762 million. Organic order growth was $260 million , or 6.8% , over the prior year.

Water Infrastructure segment orders increased $155 million , or 7.9% , to $2,112 million ( 7.1% growth on a constant currency basis). Orders benefited from $16 million of foreign currency translation for the year and included organic growth of $139 million, or 7.1%. The majority of the organic order growth for the segment came from the transport application, driven by the public utility sector in the United States, as well as strong project orders in China and India. Additionally, dewatering distributor orders increased driven by storm related activity and the strengthening of the oil and gas markets. Treatment applications also had strong order intake, primarily from projects in the emerging markets, Latin America and North America.

Orders increased in our Applied Water segment by $71 million , or 5.1% , to $1,476 million ( 4.8% increase on a constant currency basis). The order increase was primarily due to organic order growth of $79 million, or 5.6% , driven by strength in the emerging markets and strong commercial building and industrial performance in North America, which was partially offset by the loss of orders related to divested businesses of $11 million.

Orders increased in our Measurement & Control Solutions segment by $818 million, or 177.1%, to $1,280 million (174% growth on a constant currency basis). This increase included orders from recent acquisitions, primarily Sensus, of $762 million and organic order growth of $42 million, or 9.1%, primarily from Sensus order increases in North America for most applications, as well as increased orders from test application strength in the United States and China.

Backlog includes contractual customer commitments as well as orders on hand as of the end of the period. Delivery schedules vary from customer to customer based upon their requirements. Annual or multi-year contracts are subject to rescheduling and cancellation by customers due to the long-term nature of the contracts. As such, beginning total backlog, plus orders, minus revenues will not equal ending total backlog due to contract adjustments, foreign currency fluctuations and other factors. Typically, large projects require longer lead production cycles and deployment schedules, and delays can occur from time to time. Total backlog was $1,513 million at December 31, 2017 and $1,292 million at December 31, 2016 , an increase of 17%. The December 31, 2016 backlog balance has been revised to include contractual agreements that Sensus has with customers that do not have minimum commitments but which we believe will be executed upon over the terms of the contracts. This year over year increase in backlog of $221 million is due to strong order growth in the fourth quarter across all of our segments as well as benefits from currency translation impacts. We anticipate that over 60% of our total backlog at December 31, 2017 will be recognized as revenue during 2018 .

Gross Margin

Gross margins as a percentage of consolidated revenue increased to 39.3% in 2017 from 38.7% in 2016 . The gross margin increase was primarily due to the benefits realized from cost reductions from global procurement and continuous improvement initiatives, as well as a decrease in the inventory step-up charge for Sensus in 2017. These positive impacts on gross margin were partially offset by cost inflation and unfavorable product mix.

Selling, General and Administrative Expenses

SG&A increased by $175 million (increase of 19.1% ) to 23.2% of revenue in 2017 , as compared to 24.3% of revenue in 2016 . The increase in SG&A expenses includes approximately $160 million of incremental SG&A spending for the Sensus business that we did not have prior to the acquisition in the fourth quarter of 2016. The remaining increases in SG&A expenses were primarily due to inflation, investments in regional sales channels and operational capabilities and foreign currency impacts, which were partially offset by savings from restructuring and other cost actions.

Research and Development Expenses

R&D spending increased $70 million or 63.6% to 3.8% of revenue in 2017 as compared to 2.9% of revenue in 2016 primarily due to additional R&D spend from our recent acquisitions and investments in new products and technologies.

Restructuring Charges and Asset Impairment

Restructuring Charges

During 2017 , we incurred restructuring costs of $7 million , $8 million and $5 million in our Water Infrastructure, Applied Water and Measurement & Control Solutions segments, respectively. We incurred these charges related to actions taken in 2017 primarily as a continuation of our efforts to reposition our European and North American businesses to optimize our cost structure and improve our operational efficiency and effectiveness. The charges included the reduction of headcount and consolidation of facilities within our Applied Water and Water Infrastructure segments, as well as headcount reductions within our Measurement & Control Solutions segment.

During 2016 , we recognized restructuring costs of $12 million, $10 million, $6 million and $2 million in our Water Infrastructure, Applied Water, Measurement & Control Solutions and Corporate, respectively. These charges were incurred primarily in an effort to realign our organizational structure in Europe and North America to optimize our cost structure. The charges relate to the reduction in structural costs, including a decrease in headcount and consolidation of facilities.

The following table presents expected restructuring spend:

The Water Infrastructure, Applied Water, Measurement & Control Solutions, and Corporate actions commenced in 2017 consist primarily of severance charges and are expected to continue through the end of 2018. The Water Infrastructure, Applied Water, Measurement & Control Solutions and Corporate actions commenced in 2016 consist primarily of severance charges and are largely complete. The Water Infrastructure, Applied Water and Measurement & Control Solutions actions commenced in 2015 consist primarily of severance charges and are complete. As a result of these actions initiated in 2017, we achieved savings of approximately $4 million in 2017 and estimate annual future net savings beginning in 2018 of approximately $9 million, resulting in $5 million of incremental savings from the 2017 actions.

Asset Impairment Charges

During the first quarter of 2017 we determined that certain assets within our Applied Water segment, including a tradename, were impaired. Accordingly we recognized an impairment charge of $5 million. Refer to Note 10, "Goodwill and Other Intangible Assets," for additional information.

Operating Income

We generated operating income of $556 million (operating margin of 11.8%) during 2017 , reflecting an increase of $150 million , or 36.9% , when compared to operating income of $ 406 million (operating margin of 10.8%) during the prior year. This increase in operating income was largely driven by the inclusion of Sensus operating income for the

full year in 2017. Sensus acquisition related costs and restructuring and realignment costs decreased $31 million and $6 million, respectively, while special charges increased $6 million when compared to the prior year period. Excluding these costs, adjusted operating income was $630 million (adjusted operating margin of 13.4%) for 2017 as compared to $511 million (adjusted operating margin of 13.6%) for 2016. The decrease in adjusted operating margin was mostly due to cost inflation increases, increased spending on strategic investments and Sensus purchase accounting impacts, which were largely offset by cost savings from our global procurement and productivity initiatives and restructuring savings. The non-cash Sensus purchase accounting impact on adjusted operating margin for the year was 50 basis points.

Water Infrastructure

Operating income for our Water Infrastructure segment increased $17 million , or 5.8% , with operating margin also increasing from 15.1% to 15.4% , a 30 basis point increase as compared to the prior year. Operating margin was positively impacted year over year by special charges of $2 million in 2016 that did not recur, while restructuring and realignment costs remained flat. Excluding these items, adjusted operating income increased $15 million , or 4.9% , with adjusted operating margin increasing from 16.0% to 16.2% , a 20 basis point increase as compared to the prior year. The increase in adjusted operating margin was primarily due to cost reductions from global procurement and continuous improvement initiatives as well as restructuring savings and favorable volume. These drivers were partially offset by increases in cost inflation and spending on strategic investments, as well as unfavorable transactional foreign currency impacts.

Applied Water

Operating income for our Applied Water segment increased $9 million , or 4.8% , with operating margin also increasing from 13.5% to 13.9% , a 40 basis point increase as compared to the prior year. Operating margin was negatively impacted by higher special charges for a non-cash impairment of $5 million and a $1 million increase in restructuring and realignment costs. Excluding these items, adjusted operating income increased $15 million , or 7.4% , with adjusted operating margin increasing from 14.6% to 15.4% , an 80 basis point increase as compared to the prior year. The increase in adjusted operating margin was primarily due to cost reductions from global procurement and continuous improvement initiatives and restructuring savings, which were partially offset by increases in cost inflation and unfavorable mix.

Measurement & Control Solutions

Operating income for our Measurement & Control Solutions segment increased $110 million (operating margin of 8.6%) for the year as compared to operating income and margin of zero in 2016. Operating margin was positively impacted by decreases in Sensus acquisition related costs, restructuring and realignment costs and special charges of $10 million, $5 million and $3 million, respectively. Excluding these items, adjusted operating income increased $92 million, or 224.4%, with most of the increase coming from the inclusion of the incremental adjusted operating income for Sensus in 2017. Adjusted operating margin increased from 9.2% to 10.4%, a 120 basis point increase as compared to the prior year. The increase in adjusted operating margin was primarily due to cost reductions from global procurement and continuous improvement initiatives, restructuring savings and favorable volume impacts. These drivers were partially offset by the inclusion of Sensus margins, which were negatively impacted by purchase accounting. Non-cash Sensus purchase accounting negatively impacted the segment's full year adjusted operating margin by 200 basis points.

Corporate and other

Operating expense for corporate and other decreased $14 million , or 19.2% , compared to the prior year, primarily due to a $21 million decrease in Sensus acquisition related costs and a $2 million decrease in restructuring and realignment costs. This was partially offset by $6 million of special charges incurred during the year which we did not have in the prior year. Excluding these costs, adjusted operating expense increased $3 million compared to the prior year, driven mostly by employee related costs.

Interest Expense

Interest expense was $82 million and $70 million for 2017 and 2016 , respectively. The increased interest expense for the the year includes additional interest expense in 2017 related to debt entered into in the fourth quarter of 2016 to fund our acquisition of Sensus. The increase in interest expense was partially offset by the reduction in special interest charges incurred in 2016 of $8 million in connection with the early extinguishment of our Senior Notes due in 2016 and $5 million of financing charges on the bridge loan related to the Sensus acquisition, neither of which recurred in 2017, as well as a lower interest rate on the Senior Notes due 2023 which effectively replaced the Senior Notes due in 2016. See Note 13, "Credit Facilities and Debt" of our consolidated financial statements for a description of our credit facilities and long-term debt and related interest.

Income Tax Expense

The income tax provision for 2017 was $136 million at an effective tax rate of 29.2% compared to $80 million at an effective tax rate of 23.5% in 2016 . The 2017 effective tax rate is higher than 2016 due to the provisional one time deemed repatriation transition tax under the newly enacted Tax Cuts and Jobs Act, partially offset by the benefit from the remeasurement of deferred tax assets and liabilities and the release of valuation allowances.

Tax Act

On December 22, 2017, the U.S. government enacted comprehensive tax legislation commonly referred to as the Tax Cuts and Jobs Act (the “Tax Act”). The Tax Act makes broad and complex changes to the U.S. tax code, including, but not limited to, (1) reducing the U.S. federal corporate tax rate from 35 percent to 21 percent; (2) requiring companies to pay a one-time transition tax on certain unrepatriated foreign earnings of foreign subsidiaries; (3) generally eliminating U.S. federal income taxes on dividends from foreign subsidiaries; (4) requiring a current inclusion in U.S. federal taxable income of certain earnings of controlled foreign corporations; (5) eliminating the corporate alternative minimum tax (AMT) and changing how existing AMT credits can be realized; (6) creating the base erosion anti-abuse tax (BEAT), a new minimum tax; (7) creating a new limitation on deductible interest expense; and (8) changing rules related to uses and limitations of net operating loss carryforwards created in tax years beginning after December 31, 2017.

In connection with our initial analysis of the impact of the Tax Act, we have recorded a provisional tax expense of $46 million as a discrete item. This net income tax expense primarily consists of a tax benefit for the corporate tax rate reduction of $107 million related to the remeasurement of deferred tax assets and liabilities and a tax expense for the repatriation transition tax of $153 million. As permitted under SAB 118, we have not completed our accounting for the income tax effects of certain elements of the Tax Act, and have recorded provisional estimates related to these items. For certain items, a provisional estimate could not be determined, and therefore, we have continued accounting for them in accordance with ASC 740 on the basis of the tax laws in effect before the Tax Act. See Note 6, "Income Taxes" of our consolidated financial statements for further discussion of the Tax Act.

Other Comprehensive Income

Other comprehensive income was $108 million in 2017 as compared to an $80 million loss in 2016 . This increase was driven primarily by favorable foreign currency translation impacts, primarily due to the strengthening of the Euro, Great British Pound, Chinese Yuan, Polish Zloty, amongst other various currencies, against the U.S. Dollar as compared to the weakening of these same currencies in the prior year. Partially offsetting these favorable movements, was the Euro movement on the Company's net investment hedge as compared to the prior year. The tax impact on the foreign currency translation related to the net investment hedge also contributed to the year over year increase. Finally, year over year movement in foreign currency translation on postretirement benefit plans partially offset the increase in other comprehensive income.

2016 versus 2015

Revenue

Revenue generated for 2016 was $3,771 million, an increase of $118 million, or 3.2%, compared to $3,653 million in 2015. On a constant currency basis, revenue grew 5.3%. This increase in revenue was primarily driven by additional revenue of $163 million from acquisitions. Additionally, we had strong organic growth, driven by strength within the public utility, industrial and commercial end markets in western Europe, particularly in the United Kingdom, as well as large project deliveries in emerging markets, including India and Asia. Partially offsetting this growth were declines in the United States primarily due to ongoing weakness in the industrial end market.

The following table illustrates the impact on 2016 revenue from organic growth, recent acquisitions/divestitures, and foreign currency translation in relation to revenue.



	Water Infrastructure					Applied Water					Measurement & Control Solutions					Total Xylem
(in millions)	$ Change			% Change		$ Change			% Change		$ Change			% Change		$ Change			% Change

(a)	Foreign currency translation impact primarily due to fluctuations in the value of the British Pound, Chinese Yuan, Argentinian Peso and other various currencies against the U.S. Dollar.

Water Infrastructure

Water Infrastructure’s revenue decreased $8 million, or 0.4%, in 2016 (2.3% increase on a constant currency basis) compared to 2015. The constant currency increase included organic growth of $44 million, or 2.3%.

Organic growth in our treatment and transport applications primarily reflect increases in the public utility end market where we have been gaining share. Organic growth in the transport application in the public utility end markets in the United States and India was largely offset by declines in the industrial dewatering business in the United States due to continued challenges in the oil and gas market, as well as weakness in the Middle East driven by slower government funding. Organic growth in the treatment application was driven primarily by strong backlog execution and project deliveries in the United States public utility market.

Applied Water

Applied Water’s revenue decreased $29 million, or 2.0%, in 2016 (0.6% decrease on a constant currency basis) compared to 2015. The decline on a constant currency basis was entirely attributable to organic revenue decline of $9 million, or 0.6%, which was driven by declines in the United States, partially offset by growth in western Europe and, to a lesser extent, the emerging markets.

From an applications perspective, the decrease in organic revenue was predominately due to declines in the United States across all applications, particularly industrial water which saw continued weakness in the oil and gas markets. These declines were partially offset by strength in western Europe due to several large projects combined with strength in commercial building services as well as general industrial applications. Agricultural applications declined in the United States primarily due to market weakness.

Measurement & Control Solutions

Measurement & Control Solutions' revenue increased $155 million, or 53.3%, in 2016 (54.0% increase on a constant currency basis) compared to 2015. The constant currency increase included contributions from acquisitions of $163 million which was partially offset by an organic decline of $6 million, or 2.1%, due to weakness from test applications in the United States primarily as a result of lower government agency spending and weakness in the mining and oil and gas markets.

Orders/Backlog

Orders received during 2016 increased by $113 million, or 3.0%, to $3,824 million (5.1% increase on a constant currency basis). The order growth on a constant currency basis was primarily made up of orders from recent acquisitions, primarily Sensus, of $179 million and organic order growth of $12 million, or 0.3%, over the prior year.

Water Infrastructure segment orders decreased $52 million, or 2.6%, to $1,957 million (0.1% growth on a constant currency basis). Orders were unfavorably impacted by $55 million from foreign currency translation, while orders were up slightly year over year on an organic basis. Organic orders for the treatment application increased by 5% over the prior year reflecting continued growth in the public utility market with a large ozone project in China and order increases in Europe; however, these orders are largely project based with longer lead times for delivery and recognition of revenue. Largely offsetting the organic order growth in the treatment application were declines in the transport application, primarily due to decreased dewatering orders impacted by the continued weakness in oil and gas, as well as mining, which were partially offset by public utility water and wastewater transport order strength in Europe, particularly in the Nordic region.

Orders decreased in our Applied Water segment by $10 million, or 0.7%, to $1,405 million (0.7% increase on a constant currency basis). The order increase on a constant currency basis was due to organic order growth of 0.7% driven by strength in Europe from new product launches that was partially offset by weakness in the United States.

The Measurement & Control Solutions segment orders increased $175 million, or 61.0%, to $462 (62.0% increase on a constant currency basis). The order growth on a constant currency basis was primarily orders from recent acquisitions of $179 million. Organic orders from test applications were flat versus the prior year.

Backlog includes contractual customer commitments as well as purchase orders on hand as of the end of the period. Delivery schedules vary from customer to customer based upon their requirements. Annual or multi-year contracts are subject to rescheduling and cancellation by customers due to the long-term nature of the contracts. As such, beginning total backlog, plus orders, minus revenues will not equal ending total backlog due to contract adjustments, foreign currency fluctuations and other factors. Typically, large projects require longer lead production cycles, and delays can occur from time to time. Total backlog was $1,292 million at December 31, 2016 and $716 million at December 31, 2015. The December 31, 2016 backlog balance has been revised to include contractual agreements that Sensus has with customers that do not have minimum commitments but which we believe will be

executed upon over the terms of the contracts. This increase is primarily attributable to the acquisition of the Sensus business which had a backlog balance of $599 million at December 31, 2016.

Gross Margin

Gross margins as a percentage of consolidated revenue increased to 38.7% in 2016 from 38.4% in 2015. The gross margin increase was primarily due to the benefits realized from cost saving initiatives through global sourcing and lean six sigma, partially offset by material and labor inflation headwinds and unfavorable currency impacts and mix.

Selling, General and Administrative Expenses

SG&A increased by $61 million (increase of 7.1%) to 24.3% of revenue in 2016, as compared to 23.4% of revenue in 2015. The increase in SG&A expenses includes $28 million of Sensus acquisition related costs. The remaining increases in SG&A expenses were primarily due to additional operating expenses from recent acquisitions, investments in regional sales channels and operational capabilities and inflation, which were partially offset by savings from restructuring and other cost actions.

Research and Development Expenses

R&D spending increased $15 million or 15.8% to 2.9% of revenue in 2016 as compared to 2.6% of revenue in 2015 primarily due to additional R&D spend from our recent acquisitions and investments in new products and technologies.

Restructuring Charges

During 2016, we incurred restructuring costs of $12 million, $10 million, $6 million and $2 million in our Water Infrastructure, Applied Water, Measurement & Control Solutions and Corporate and other segments, respectively. These charges were incurred primarily in an effort to realign our organizational structure in Europe and North America to optimize our cost structure. The charges relate to the reduction in structural costs, including a decrease in headcount and consolidation of facilities.

During 2015, we recognized restructuring costs of $4 million, $1 million, and $1 million in our Water Infrastructure, Applied Water, and Monitoring & Control Solutions segments, respectively. These charges were incurred primarily in an effort to realign our organizational structure in Europe and North America to optimize our cost structure. The charges relate to the reduction in structural costs, including a decrease in headcount and consolidation of facilities.

The following table presents expected restructuring spend:



(in millions)	Water Infrastructure		Applied Water		Measurement & Control Solutions		Corporate		Total
Actions Commenced in 2016:
Total expected costs	$	13	$	14	$	10	$	2	$	39
Costs incurred during 2016	11		10		6		2		29
Total expected costs remaining	$	2	$	4	$	4	$	—	$	10

Costs incurred during 2016	1		—		—		—		1
Total expected costs remaining	$	—	$	—	$	—	$	—	$	—

Approximate total expected costs associated with actions that commenced during 2016 are $13 million for Water Infrastructure, $14 million for Applied Water, $10 million for Measurement & Control Solutions, and $2 million for Corporate. These costs primarily comprise severance charges. The Water Infrastructure and Applied Water actions are expected to continue through the end of 2017. The Measurement & Control Solutions actions are expected to continue through 2018. All of the costs associated with the Corporate actions have been incurred. As a result of these actions initiated in 2016, we achieved savings of approximately $8 million in 2016 and estimate annual future net savings beginning in 2017 of approximately $28 million, resulting in $20 million of incremental savings from the 2016 actions.

Operating Income

We generated operating income of $406 million during 2016, reflecting a decrease of $43 million or 9.6% from $449 million during the prior year. Operating income as a percentage of revenue was 10.8% for 2016 versus 12.3% for 2015, a decrease of 150 basis points. This decrease in operating margin was primarily due to Sensus acquisition related costs of $53 million, increases in restructuring and realignment costs of $27 million and increases in special charges of $4 million. Excluding these costs, adjusted operating income was $511 million, with an adjusted operating margin of 13.6%, reflecting an increase of $41 million or 8.7% and 70 basis points, respectively, as compared with 2015 adjusted operating income of $470 million (adjusted operating margin of 12.9%). This increase in adjusted operating income was driven by strong progress in our productivity initiatives and cost saving actions, which more than offset cost inflation, spending on strategic investments in new products and technologies and unfavorable mix.

The table below provides a reconciliation of the total and each segment's operating income to adjusted operating income, and a calculation of the corresponding adjusted operating margin:

NM Not Meaningful

Water Infrastructure

Operating income for our Water Infrastructure segment increased $30 million or 11.5%, with operating margin also increasing from 13.5% to 15.1%, a 160 basis point increase as compared to the prior year. Operating margin was negatively impacted by a $5 million increase in restructuring and realignment costs and a $1 million increase for special charges. Excluding restructuring and realignment costs and special charges, adjusted operating income increased $36 million or 13.2%, with adjusted operating margin increasing from 14.1% to 16.0%, a 190 basis point increase as compared to the prior year. The increase in adjusted operating margin was due to global procurement and continuous improvement initiatives, which more than offset cost inflation and increased spending in growth initiatives.

Applied Water

Operating income for our Applied Water segment decreased $2 million or 1.1%, with operating margin increasing slightly from 13.4% to 13.5%. Operating margin was negatively impacted by increased restructuring and realignment costs of $9 million. Excluding restructuring and realignment costs, adjusted operating income increased $7 million or 3.6%, with adjusted operating margin increasing from 13.9% to 14.6%, a 60 basis point increase as compared to the prior year. The increase in adjusted operating margin was due to global procurement and productivity gains, which more than offset cost inflation, strategic investments and unfavorable mix.

Measurement & Control Solutions

Operating income for our Measurement & Control Solutions segment was $0 million, a decrease of $42 million. Operating income was negatively impacted by $25 million of Sensus acquisition related costs in 2016 and increases in restructuring and realignment and special charges of $11 million and $3 million, respectively. Excluding these costs, adjusted operating income decreased $3 million, or 6.8%, with adjusted operating margin decreasing from 15.1% to 9.2%, a 590 basis point decrease as compared to the prior year. The decrease in operating margin was largely due to negative impacts from acquisitions as well as increased spending on strategic investments.

Corporate and other

Operating loss for corporate and other increased $29 million or 65.9% (decreased $1 million or 2.3% on an adjusted basis) compared to the prior year, primarily due to $28 million of Sensus acquisition related costs and increased restructuring costs of $2 million.

Interest Expense

Interest expense was $70 million and $55 million for 2016 and 2015, respectively, primarily related to interest on our Senior Notes, including a make-whole interest premium of $7 million that was paid in the second quarter of 2016 and fees of $5 million related to the Bridge Facility entered into for the Sensus acquisition. See Note 13, “Credit Facilities and Long-Term Debt,” for further details.

Income Tax Expense

The income tax provision for 2016 was $80 million at an effective tax rate of 23.5% compared to $63 million at an effective tax rate of 15.6% in 2015. The 2016 effective tax rate is higher than 2015 due to an increase in valuation allowance and impact of repatriation of foreign earnings offset by a favorable settlement with the tax authorities.

Other Comprehensive (Loss) Income

Other comprehensive loss before tax of $57 million in 2016 as compared to $130 million loss in 2015 was primarily due to foreign currency translation loss of $65 million in 2016 compared to a loss of $180 million for 2015. Contributing to this decreased loss was a lower translation loss of $115 million primarily due to less weakening of the Swedish Krona and the Canadian Dollar against the U.S. Dollar, partially offset by the additional weakening of the Euro and the Great British Pound against the U.S. Dollar. Additionally, there were net investment hedges in place that more than offset the weakening of the Euro against the U.S. Dollar, contributing a net Euro gain into comprehensive income in 2016. Other items offsetting the lower translation loss of $115 million were net changes in postretirement benefit plan gains/losses of $43 million.

Liquidity and Capital Resources

(a)	2017 impact is primarily due to the strengthening of the Euro and the Chinese Yuan against the U.S. Dollar. 2016 impact is primarily due to the weakness of the Euro and the Chinese Yuan against the U.S. dollar. 2015 impact is primarily due to the weakness of the Euro against the U.S. Dollar.

Sources and Uses of Liquidity

Operating Activities

During 2017 , net cash provided by operating activities was $686 million , compared to $497 million in 2016 . The $189 million year-over-year increase was primarily driven by increased cash from operating activities of the Sensus business acquired in the fourth quarter of 2016 and strong operating cash performance across the rest of the business.

During 2016 , net cash provided by operating activities was $497 million , compared to $464 million in 2015 . The $33 million year-over-year increase was primarily driven by continued improvement in working capital levels. The improvement in working capital includes significant contribution from the acquisition of Sensus during the fourth quarter of 2016 which has positively impacted our working capital efficiency.

Investing Activities

Cash used in investing activities was $181 million in 2017 , compared to $1,886 million in 2016 . This decrease of $1,705 million was primarily driven by the $1,782 million spent on the acquisition of Sensus and two other businesses in 2016 as compared to the $33 million spent for acquisitions in 2017. This impact is partially offset by increased spending of $46 million over the prior year on capital projects, including spending on capitalized software in the Sensus business.

Cash used in investing activities was $1,886 million in 2016 compared to $132 million in 2015 . The increase of $1,754 million was primarily due to $1,782 million spent on the acquisition of Sensus and two other businesses in 2016 as compared to $18 million in 2015. Cash provided from other investing activities partially offset the usage.

Financing Activities

Cash used by financing activities was $421 million in 2017 , compared to cash generated by financing activities of $1,034 in 2016. In 2017, the net decrease in cash provided was primarily due to the issuance of long term and short term debt related to acquisition financing in 2016 versus the net repayment of short-term debt in 2017 (see Note 13, "Credit Facilities and Long-Term Debt" of our consolidated financial statements for a full discussion of debt activities). Also contributing to the decrease in cash generated by financing activities were increased share repurchases and higher dividend payments in 2017.

Cash generated by financing activities was $1,034 million in 2016. In 2015, financing activities used $262 million of cash. In 2016, the net increase in cash provided was due to the issuance of long term and short term debt related to acquisition financing and a reduction in share repurchases. This increase was partially offset by net repayments of short term debt (see Note 13, "Credit Facilities and Long-Term Debt" of our consolidated financial statements for a full discussion of debt activities) and higher dividend payments.

Funding and Liquidity Strategy

Our ability to fund our capital needs depends on our ongoing ability to generate cash from operations and access to bank financing and the capital markets. Historically, we have generated operating cash flow sufficient to fund our primary cash needs centered on operating activities, working capital, capital expenditures, strategic investments and dividends. If our cash flows from operations are less than we expect, we may need to incur debt or issue equity. From time to time, we may need to access the long-term and short-term capital markets to obtain financing. Our access to, and the availability of, financing on acceptable terms and conditions in the future will be impacted by many factors, including: (i) our credit ratings or absence of a credit rating, (ii) the liquidity of the overall capital markets, and (iii) the current state of the economy. There can be no assurance that such financing will be available to us on acceptable terms or that such financing will be available at all.

We monitor our global funding requirements and seek to meet our liquidity needs on a cost effective basis. Based on our current global cash positions, cash flows from operations and access to the commercial paper markets, we believe there is sufficient liquidity to meet our funding requirements. In addition, our existing committed credit facilities and access to the public debt markets would provide further liquidity if required.

We anticipate that our present sources of funds, including funds from operations and additional borrowings, will provide us with sufficient liquidity and capital resources to meet our liquidity and capital needs in both the United States and outside of the United States over the next twelve months.

Credit Facilities & Long-Term Contractual Commitments

See Note 13, "Credit Facilities and Long-Term Debt" of our consolidated financial statements for a description of our credit facilities and long-term debt.

Non-U.S. Operations

For 2017 and 2016 , we generated 54% and 58% of our revenue from non-U.S. operations, respectively. While the addition of Sensus increases our revenue profile in the U.S., we continue to grow our operations in the emerging markets and elsewhere outside of the United States. As such, we expect to continue to generate significant revenue from non-U.S. operations and expect a substantial portion of our cash will be predominately held by our foreign subsidiaries. We expect to manage our worldwide cash requirements considering available funds among the many subsidiaries through which we conduct business and the cost effectiveness with which those funds can be accessed. We may transfer cash from certain international subsidiaries to the U.S. and other international subsidiaries when we believe it is cost effective to do so. We continually review our domestic and foreign cash profile, expected future cash generation and investment opportunities and reassess whether there is a need to repatriate funds held internationally to support our U.S. operations. As of December 31, 2017 , we have provided a deferred tax liability of $20 million for foreign withholding taxes and state income taxes on $769 million expected to be repatriated to the U.S. parent as deemed necessary.

Contractual Obligations

The following table summarizes our contractual commitments as of December 31, 2017 :

In addition to the amounts presented in the table above, we have recorded liabilities for net investment hedges of $64 million and employee severance indemnity of $16 million . These amounts have been excluded from the contractual obligations table due to an inability to reasonably estimate the timing or amounts of such payments in individual years. Further, benefit payments which reflect expected future service related to the Company's pension and other postretirement employee benefit obligations are presented in Note 14 , “Postretirement Benefit Plans” of the consolidated financial statements and deferred income tax liabilities and uncertain tax positions are presented in Note 6, "Income Taxes" of the consolidated financial statements, and as such, these obligations are not included in the above table. Finally, estimated environmental payments and workers' compensation and general liability reserves are excluded from the table above. We estimate, based on historical experience, that we will spend approximately $2 million to $3 million per year on environmental investigation and remediation and approximately $6 million to

$7 million per year on workers' compensation and general liability. At December 31, 2017 , we had estimated and accrued $4 million and $30 million related to environmental matters, and workers' compensation and general liability, respectively.

Off-Balance Sheet Arrangements

As of December 31, 2017 , we have issued guarantees for the debt and other obligations of consolidated subsidiaries in the normal course of business. We have determined that none of these arrangements has a material current effect or is reasonably likely to have a material future effect on our consolidated financial statements, financial condition, changes in financial condition, revenues or expenses, liquidity, capital expenditures or capital resources.

We obtain certain stand-by letters of credit, bank guarantees and surety bonds from third-party financial institutions in the ordinary course of business when required under contracts or to satisfy insurance related requirements. As of December 31, 2017 , the amount of stand-by letters of credit, bank guarantees and surety bonds was $240 million .

Critical Accounting Estimates

The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets, liabilities, revenue and expenses, and the disclosure of contingent liabilities. Management bases its estimates on historical experience and on various other assumptions that it believes to be reasonable under the circumstances, the results of which form the basis for making judgments about the carrying values of assets and liabilities that are not readily apparent from other sources.

Significant accounting policies used in the preparation of the Consolidated Financial Statements are discussed in Note 1, “Summary of Significant Accounting Policies,” of the consolidated financial statements. Accounting estimates and assumptions discussed in this section are those that we consider most critical to an understanding of our financial statements because they are inherently uncertain, involve significant judgments, include areas where different estimates reasonably could have been used, and changes in the estimate that are reasonably possible could materially impact the financial statements. Management believes that the accounting estimates employed and the resulting balances are reasonable; however, actual results in these areas could differ from management’s estimates under different assumptions or conditions.

Revenue Recognition. We recognize revenue when persuasive evidence of an arrangement exists, delivery has occurred, the sales price is fixed or determinable, and collectability of the sales price is reasonably assured. For product sales, delivery does not occur until the products have been shipped, risk of loss has been transferred to the customer and the contractual terms have been fulfilled. In instances where contractual terms include a provision for customer acceptance, revenue is recognized when either (i) we have previously demonstrated that the product meets the specified criteria based on either seller- or customer-specified objective criteria or (ii) upon formal acceptance received from the customer where the product has not been previously demonstrated to meet customer-specified objective criteria. Revenue on service and repair contracts is recognized after services have been agreed to by the customer and rendered.

We enter into contracts to sell our products and services, and while the majority of our sales agreements contain standard terms and conditions, certain agreements contain multiple elements or non-standard terms and conditions. Where sales agreements contain multiple elements or non-standard terms and conditions, judgment is required to determine the appropriate accounting, including whether the deliverables specified in these agreements should be treated as separate units of accounting for revenue recognition purposes, and, if so, how the transaction price should be allocated among the elements and when to recognize revenue for each element. When a sale involves multiple deliverables, the total revenue from the arrangement is allocated to each unit of accounting based on the relative selling price of the deliverable to all other deliverables in the contract. Revenue for multiple element arrangements is recognized when the appropriate revenue recognition criteria for the individual deliverable have been satisfied. Generally, these elements are satisfied within the same reporting period although certain contracts may be completed over 6 months. The allocation of sales price between elements may impact the timing of

revenue recognition, but will not change the total revenue recognized on the arrangement. For delivered elements accounted for as separate units of accounting in a multiple element arrangement, revenue is recognized only when the delivered elements have standalone value, there are no uncertainties regarding customer acceptance and there are no customer-negotiated refund or return rights affecting the sales recognized.

Certain businesses enter into long-term construction-type sales contracts for which revenue is recognized under the percentage-of-completion method based upon percentage of costs incurred to total estimated costs.

We record a reduction in revenue at the time of sale for estimated product returns, rebates and other allowances, based on historical experience and known trends.

We adopted the new accounting guidance regarding revenue from contracts with customers January 1, 2018 using the modified retrospective approach (refer to Note 2 “Recently Issued Accounting Pronouncements”). Adoption of the guidance did not have a material impact on our financial statements.

Income Taxes. Deferred tax assets and liabilities are determined based on temporary differences between the financial reporting and tax bases of assets and liabilities, applying enacted tax rates in effect for the year in which we expect the differences will reverse. Based on the evaluation of available evidence, we recognize future tax benefits, such as net operating loss carryforwards, to the extent that we believe it is more likely than not we will realize these benefits. We periodically assess the likelihood that we will be able to recover our deferred tax assets and reflect any changes to our estimate of the amount we are more likely than not to realize in the valuation allowance, with a corresponding adjustment to earnings or other comprehensive income, as appropriate.

In assessing the need for a valuation allowance, we look to the future reversal of existing taxable temporary differences, taxable income in carryback years and the feasibility of tax planning strategies and estimated future taxable income. The valuation allowance can be affected by changes to tax laws, changes to statutory tax rates and changes to future taxable income estimates.

Due to U.S. Tax Reform, we have recorded provisional amounts of foreign withholding taxes and state income taxes on earnings that are expected to be repatriated to the U.S. parent. The Company intends to distribute a portion of the earnings taxed under the Tax Act. We have not recorded any deferred taxes on the amounts that the Company currently does not intend to distribute as the determination of any deferred taxes on this amount is not practicable.

The calculation of our tax liabilities involves dealing with uncertainties in the application of complex tax regulations in a multitude of jurisdictions across our global operations. We recognize potential liabilities and record tax liabilities for anticipated tax audit issues in the U.S. and other tax jurisdictions based on our estimate of whether, and to the extent to which, additional taxes will be due. Furthermore, we recognize the tax benefit from an uncertain tax position only if it is more likely than not that the tax position will be sustained on examination by the taxing authorities, based on the technical merits of the position. The tax benefits recognized in the financial statements from such a position are measured based on the largest benefit that has a greater than 50% likelihood of being realized upon ultimate settlement.

We adjust our liability for uncertain tax positions in light of changing facts and circumstances; however, due to the complexity of some of these uncertainties, the ultimate resolution may result in a payment that is materially different from our current estimate of the tax liabilities. If our estimate of tax liabilities proves to be less than the ultimate assessment, an additional tax expense would result. If a payment of these amounts ultimately proves to be less than the recorded amounts, the reversal of the liabilities would result in tax benefits being recognized in the period when we determine the liabilities are no longer necessary.

Business Combinations. We record acquisitions using the purchase method of accounting. All of the assets acquired, liabilities assumed, contractual contingencies and contingent consideration is recorded at fair value as of the acquisition date. The excess of the purchase price over the estimated fair values of the net tangible and intangible assets acquired is recorded as goodwill. The application of the purchase method of accounting for business combinations requires management to make significant estimates and assumptions in the determination of the fair value of assets acquired and liabilities assumed, in order to properly allocate purchase price consideration between assets that are depreciated and amortized from goodwill. These assumptions and estimates include a market participant’s use of the asset and the appropriate discount rates for a market participant. Our estimates are based on historical experience, information obtained from the management of the acquired companies and, when appropriate, includes assistance from independent third-party appraisal firms. Significant assumptions and estimates include, but are not limited to, the cash flows that an asset is expected to generate in the future, the cost to build/recreate certain technology, the appropriate weighted-average cost of capital, and the cost savings expected to be derived from acquiring an asset. These estimates are inherently uncertain and

unpredictable. In addition, unanticipated events and circumstances may occur which may affect the accuracy or validity of such estimates.

Goodwill and Intangible Assets. We review goodwill and indefinite-lived intangible assets for impairment annually and whenever events or changes in circumstances indicate the carrying value of an asset may not be recoverable. We also review the carrying value of our finite-lived intangible assets for potential impairment when impairment indicators arise. We conduct our annual impairment test as of the first day of the fourth quarter. For goodwill, the estimated fair value of each reporting unit is compared to the carrying value of the net assets assigned to that reporting unit. If the estimated fair value of the reporting unit exceeds its carrying value, goodwill is not impaired. If the carrying value of the reporting unit exceeds its estimated fair value, then an impairment charge is recognized for that excess up to the amount of recorded goodwill. We estimate the fair value of our reporting units and intangible assets with indefinite lives using an income approach. Under the income approach, we calculate fair value based on the present value of estimated future cash flows.

Determining the fair value of a reporting unit or an indefinite-lived intangible asset is judgmental in nature and involves the use of significant estimates and assumptions, particularly related to future operating results and cash flows. These estimates and assumptions include, but are not limited to, revenue growth rates and operating margins used to calculate projected future cash flows, risk-adjusted discount rates, assumed royalty rates, future economic and market conditions and identification of appropriate market comparable data. In addition, the identification of reporting units and the allocation of assets and liabilities to the reporting units when determining the carrying value of each reporting unit also require judgment. Goodwill is tested for impairment at either the operating segment identified in Note 20 , “Segment and Geographic Data,” of the consolidated financial statements, or one level below. The fair value of our reporting units and indefinite-lived intangible assets is based on estimates and assumptions that are believed to be reasonable. Significant changes to these estimates and assumptions could adversely impact our conclusions. Actual future results may differ from those estimates.

During the fourth quarter of 2017 , we performed our annual impairment assessment and determined that the estimated fair values of our goodwill reporting units were substantially in excess of each of their carrying values. However, future goodwill impairment tests could result in a charge to earnings. We will continue to evaluate goodwill on an annual basis as of the beginning of our fourth quarter and whenever events and changes in circumstances indicate there may be a potential impairment. We determined that no impairment of the indefinite-lived intangibles existed as of the measurement date in 2017 . However, future indefinite-lived intangible impairment tests could result in a charge to earnings. We will continue to evaluate indefinite-lived intangibles on an annual basis as of the beginning of our fourth quarter and whenever events and changes in circumstances indicate there may be a potential impairment.

Contingent Liabilities. As discussed in Note 18 , "Commitments and Contingencies" of the consolidated financial statements, the Company is, from time to time, subject to a variety of litigation, environmental liabilities, product liabilities, and similar contingent liabilities incidental to its business (or the business operations of previously owned entities). The Company recognizes a liability for any contingency that is known or probable of occurrence and reasonably estimable. These assessments require judgments concerning matters such as litigation developments and outcomes, the anticipated outcome of negotiations, the number of future claims and the cost of both pending and future claims. In addition, because most contingencies are resolved over long periods of time, liabilities may change in the future due to various factors, including those discussed in Note 18 of the consolidated financial statements. If the liabilities established by the Company with respect to these contingencies are inadequate, the Company would be required to incur an expense equal to the amount of the loss incurred in excess of the recorded liability, which would adversely affect the Company’s financial statements.

Receivables and Allowance for Doubtful Accounts and Discounts. Receivables primarily comprise uncollected amounts owed to us from transactions with customers and are presented net of allowances for doubtful accounts and early payment discounts.

We determine our allowance for doubtful accounts using a combination of factors to reduce our trade receivable balances to their estimated net realizable amount. We maintain an allowance for doubtful accounts based on a variety of factors, including the length of time receivables are past due, macroeconomic trends and conditions, significant one-time events, historical experience and the financial condition of customers. In addition, we record a specific reserve for individual accounts when we become aware of specific customer circumstances, such as in the case of bankruptcy filings or deterioration in the customer’s operating results or financial position. The past due or delinquency status of a receivable is based on the contractual payment terms of the receivable. If circumstances related to the specific customer change, we adjust estimates of the recoverability of receivables as appropriate. We determine our allowance for early payment discounts primarily based on historical experience with customers.

Credit risk with respect to accounts receivable is generally diversified due to the large number of entities comprising our customer base and their dispersion across many different geographical regions. We perform ongoing credit evaluations of the financial condition of our third-party distributors, resellers and other customers and require collateral, such as letters of credit and bank guarantees, in certain circumstances. As of December 31, 2017 and 2016 we do not believe we have any significant concentrations of credit risk.

Postretirement Plans. Company employees around the world participate in numerous defined benefit plans. The determination of projected benefit obligations and the recognition of expenses related to these plans are dependent on various assumptions. These major assumptions primarily relate to discount rates, expected long-term rates of return on plan assets, rate of future compensation increases, mortality, health care inflation and years of service (some of which are disclosed in Note 14 , “Postretirement Benefit Plans,” of the consolidated financial statements) and other factors. Actual results that differ from our assumptions are accumulated and amortized on a straight-line basis only to the extent they exceed 10% of the higher of the market-related value or projected benefit obligation, over the average remaining service period of active plan participants, or for plans with all or substantially all inactive participants, over the average remaining life expectancy.

Significant Assumptions

Management develops each assumption using relevant Company experience, in conjunction with market-related data for each individual country in which such plans exist. All assumptions are reviewed annually with third-party consultants and adjusted as necessary. The table included below provides the weighted average assumptions used to estimate our defined benefit pension obligations and costs as of and for the years ended 2017 and 2016 .



	2017				2016
	U.S.		Int’l		U.S.		Int’l
Benefit Obligation Assumptions
Discount rate	3.75	%	2.43	%	4.25	%	2.63	%
Rate of future compensation increase	NM		2.93	%	NM		2.76	%
Net Periodic Benefit Cost Assumptions
Discount rate	4.25	%	2.63	%	4.27	%	3.44	%
Expected long-term return on plan assets	8.00	%	7.20	%	8.00	%	7.25	%
Rate of future compensation increase	NM		2.76	%	NM		3.29	%


NM	Not meaningful. The pension benefits for future service for all the U.S. pension plans are based on years of service and not impacted by future compensation increases.

We determine the expected long-term rate of return on plan assets by evaluating both historical returns and estimates of future returns. Specifically, the Company analyzes the estimated future returns based on independent estimates of asset class returns and evaluates historical broad market returns over long-term timeframes based on the strategic asset allocation, which is detailed in Note 14 , “Postretirement Benefit Plans,” of the consolidated financial statements.

Based on the approach described above, the chart below shows weighted average actual returns versus the weighted average expected long-term rates of return for our pension plans that were utilized in the calculation of the net periodic pension cost for each respective year.



	2017		2016		2015
Expected long-term rate of return on plan assets	7.30	%	7.32	%	7.38	%
Actual rate of return on plan assets	5.70	%	12.20	%	3.51	%

For the recognition of net periodic pension cost, the calculation of the expected return on plan assets is generally derived by applying the expected long-term rate of return to the market-related value of plan assets. The market-related value of plan assets is based on average asset values at the measurement date over the last five years. The use of fair value, rather than a calculated value, could materially affect net periodic pension cost. The weighted average expected long-term rate of return for all of our plan assets to be used in determining net periodic benefit costs for 2018 is estimated at 7.30% . We estimate that every 25 basis point change in the expected return on plan assets impacts the expense by $1 million.

The discount rate reflects our expectation of the present value of expected future cash payments for benefits at the measurement date. A decrease in the discount rate increases the present value of benefit obligations and increases pension expense. We base the discount rate assumption on current investment yields of high-quality fixed income

investments during the retirement benefits maturity period. The pension discount rate was determined by considering an interest rate yield curve comprising AAA/AA bonds, with maturities between zero and 30 years, developed by the plan’s actuaries. Annual benefit payments are then discounted to present value using this yield curve to develop a single-point discount rate matching the plan’s characteristics. Our weighted average discount rate for all pension plans effective January 1, 2018 , is 2.58% . We estimate that every 25 basis point change in the discount rate impacts the expense by $1 million.

The rate of future compensation increase assumption reflects our long-term actual experience and future and near-term outlook. Effective January 1, 2018 , our expected rate of future compensation is 3.03% for all pension plans. The estimated impact of a 25 basis point change in the expected rate of future compensation is less than $1 million.

The assumed rate of future increases in the per capita cost of health care (the health care trend rate) is 8.72% for 2018 , decreasing ratably to 4.50% in 2026. An increase or decrease in the health care trend rates by one percent per year would impact the aggregate annual service and interest components by less than $1 million, and impact the benefit obligation by approximately $4 million.

We currently anticipate making contributions to our pension and postretirement benefit plans in the range of $20 million to $30 million during 2018 , of which $6 million is expected to be made in the first quarter.

Funded Status

Funded status is derived by subtracting the respective year-end values of the projected benefit obligations from the fair value of plan assets. We estimate that every 25 basis point change in the discount rate impacts the funded status by approximately $31 million.

Fair Value of Plan Assets

The plan assets of our pension plans comprise a broad range of investments, including domestic and foreign equity securities, interests in private equity and hedge funds, fixed income investments, insurance contracts, and cash and cash equivalents.

A portion of our pension benefit plan assets portfolio comprises investments in private equity and hedge funds. The private equity and hedge fund investments are generally measured at net asset value. However, in certain instances, the values reported by the asset managers were not current at the measurement date. Accordingly, we made estimate adjustments to the last reported value where necessary to measure the assets at fair value at the measurement date. These adjustments consider information received from the asset managers, as well as general market information. The adjustment recorded at December 31, 2017 and 2016 for these assets represented less than one percent of total plan assets in each respective year. Asset values for other positions were generally measured using market observable prices. We estimate that a 5% change in asset values will impact funded status by approximately $29 million.

ITEM 7A . QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

We are exposed to market risk, primarily related to foreign currency exchange rates and interest rates. These exposures are actively monitored by management. Our exposure to foreign exchange rate risk is due to certain costs, revenue and borrowings being denominated in currencies other than one of our subsidiaries functional currency. Similarly, we are exposed to market risk as the result of changes in interest rates which may affect the cost of our financing. It is our policy and practice to use derivative financial instruments only to the extent necessary to manage exposures.

Foreign Currency Exchange Rate Risk

We conduct approximately 54% of our business in various locations outside the United States.

Our economic foreign currency risk primarily relates to receipts from customers, payments to suppliers and intercompany transactions denominated in foreign currencies. We may use derivative financial instruments to offset risk related to receipts from customers and payments to suppliers, when it is believed that the exposure will not be limited by our normal operating and financing activities. We enter into currency forward contracts periodically in order to manage the exchange rate fluctuation risk on certain intercompany transactions associated with third party sales and purchases. These risks are also mitigated by natural hedges including the presence of manufacturing facilities outside the United States, global sourcing and other spending which occurs in foreign countries. Our principal foreign currency transaction exposures primarily relate to the Euro, Swedish Krona, Polish Zloty, Canadian Dollar, British Pound, and Australian Dollar. We estimate that a hypothetical 10% movement in foreign currency exchange rates would not have a material economic impact to Xylem’s financial position and results of operations.

Additionally, we are subject to foreign exchange translation risk due to changes in the value of foreign currencies in relation to our reporting currency, the U.S. Dollar. The translation risk is primarily concentrated in the exchange rate between the U.S. Dollar and the Euro, British Pound, Chinese Yuan, Canadian Dollar, Swedish Krona and Australian Dollar. As the U.S. Dollar strengthens against other currencies in which we transact business, revenue and income will generally be negatively impacted, and if the U.S. Dollar weakens, revenue and income will generally be positively impacted. We estimate that a hypothetical 10% movement of the U.S. Dollar to the various foreign currency exchange rates we translate from, in the aggregate, could have approximately a 5% and 6% impact on Xylem's consolidated revenue and income, respectively, as reported in U.S. Dollars. We expect to continue to generate significant revenue from non-U.S. operations and we expect our cash will be predominately held by our foreign subsidiaries. We expect to manage our worldwide cash requirements considering available funds among the many subsidiaries through which we conduct business and the cost effectiveness with which those funds can be accessed. We may transfer cash from certain international subsidiaries to the U.S. and other international subsidiaries when it is cost effective to do so, though we continually review our domestic and foreign cash profile, expected future cash generation and investment opportunities and reassess whether there is a need repatriate funds held internationally to support our U.S. operations. Accordingly, we do not expect translation risk to have a material economic impact on our financial position and results of operations.

Interest Rate Risk

As of December 31, 2017 , our long term debt portfolio is primarily comprised of four series of fixed-rate senior notes that total $2.1 billion. The senior notes are not exposed to interest rate risk as the bonds are at a fixed-rate until maturity. Based on current interest rate market we do not anticipate material risk associated with our debt refinancing within the target time-frame of completion.

Commodity Price Exposures

Portions of our business are exposed to volatility in the prices of certain commodities, such as copper, nickel and aluminum, among others. Our primary exposure to this volatility resides with the use of these materials in purchased component parts. We generally maintain long-term fixed price contracts on raw materials and component parts; however, we are prone to exposure as these contracts expire. We estimate that a hypothetical 10% adverse movement in prices for raw metal commodities would not be material to our financial position and results of operations.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

To the Board of Directors and Stockholders of

Xylem Inc.

Rye Brook, New York

Opinion on the Financial Statements

We have audited the accompanying consolidated balance sheets of Xylem Inc. and subsidiaries (the "Company") as of December 31, 2017 and 2016, the related consolidated statements of income, comprehensive income, stockholders' equity, and cash flows, for each of the three years in the period ended December 31, 2017, and the related notes (collectively referred to as the “financial statements”). In our opinion, the financial statements present fairly, in all material respects, the financial position of the Company as of December 31, 2017 and 2016, and the results of their operations and their cash flows for each of the three years in the period ended December 31, 2017, in conformity with accounting principles generally accepted in the United States of America.

We have also 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, 2017, based on the criteria established in Internal Control - Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission and our report dated February 23, 2018, expressed an unqualified opinion on the Company's internal control over financial reporting.

Basis for Opinion

These financial statements are the responsibility of the Company’s management. Our responsibility is to express an opinion on the Company’s financial statements based on our audits. We are a public accounting firm 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 financial statements are free of material misstatement, whether due to error or fraud.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

Note 1 . Summary of Significant Accounting Policies

Xylem Inc. (“Xylem” or the “Company”) is a leading equipment and service provider for water and wastewater applications with a broad portfolio of products and services addressing the full cycle of water, from collection, distribution and use to the return of water to the environment.

Xylem operates in three segments, Water Infrastructure, Applied Water and Measurement & Control Solutions. The Water Infrastructure segment focuses on the transportation and treatment of water, offering a range of products including water and wastewater pumps, treatment equipment, and controls and systems. The Applied Water segment serves many of the primary uses of water and focuses on the residential, commercial and industrial markets. The Applied Water segment’s major products include pumps, valves, heat exchangers, controls and dispensing equipment. The Measurement & Control Solutions segment focuses on developing advanced technology solutions that enable intelligent use and conservation of critical water and energy resources as well as analytical instrumentation used in the testing of water. The Measurement & Control Solutions segment's major products include smart metering, networked communications, measurement and control technologies, software and services including cloud-based analytics, remote monitoring and data management, leak detection and pressure monitoring solutions and testing equipment.

On October 31, 2011 (the "Distribution Date"), ITT Corporation (“ITT”) completed the Spin-off (the “Spin-off”) of Xylem, formerly ITT’s water equipment and services businesses. The Spin-off was completed pursuant to the Distribution Agreement, dated as of October 25, 2011 (the “Distribution Agreement”), among ITT (now ITT LLC), Exelis Inc., acquired by Harris Inc. on May 29, 2015, (“Exelis”) and Xylem. Xylem Inc. was incorporated in Indiana on May 4, 2011 in connection with the Spin-off.

Hereinafter, except as otherwise indicated or unless the context otherwise requires, “Xylem,” “we,” “us,” “our” and “the Company” refer to Xylem Inc. and its subsidiaries. References in the notes to the consolidated financial statements to “ITT” or “ former parent” refers to ITT Corporation (now ITT LLC) and its consolidated subsidiaries (other than Xylem Inc.).

Basis of Presentation

The consolidated financial statements reflect our financial position and results of operations in conformity with accounting principles generally accepted in the United States of America (“GAAP”). All intercompany transactions between our businesses have been eliminated.

Use of Estimates

The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, the disclosure of contingent assets and liabilities at the date of the financial statements, and the reported amounts of revenue and expenses during the reporting period. Estimates are revised as additional information becomes available. Estimates and assumptions are used for, but not limited to, postretirement obligations and assets, revenue recognition, income tax contingency accruals and valuation allowances, valuation of intangible assets, goodwill and indefinite lived intangible impairment testing and contingent liabilities. Actual results could differ from these estimates.

Consolidation Principles

We consolidate companies in which we have a controlling financial interest or when Xylem is considered the primary beneficiary of a variable interest entity. We account for investments in companies over which we have the ability to exercise significant influence but do not hold a controlling financial interest under the equity method, and we record our proportionate share of income or losses in the Consolidated Income Statements. Equity method investments are reviewed for impairment when events or circumstances indicate the investment may be other than temporarily impaired. This requires significant judgment, including an assessment of the investee’s financial condition, the possibility of subsequent rounds of financing, and the investee’s historical and projected results of operations. If the actual results of operations for the investee are significantly different from projections, we may incur future charges for the impairment of these investments.

Foreign Currency Translation

The national currencies of our foreign companies are generally the functional currencies. Balance sheet accounts are translated at the exchange rate in effect at the end of each period; income statement accounts are translated at the average rates of exchange prevailing during the period. Gains and losses on foreign currency translations are reflected in the cumulative translation adjustments component of stockholders’ equity. Net gains or losses from foreign currency transactions are reported currently in selling, general and administrative expenses.

Revenue Recognition

Revenue is recognized when persuasive evidence of an arrangement exists, the price is fixed or determinable, collectability is reasonably assured and delivery has occurred or services have been rendered. For product sales, other than long-term construction-type contracts, we recognize revenue at the time title, and risks and rewards of ownership pass, which is generally when products are shipped. Certain contracts with customers require delivery, installation, testing, certification or other acceptance provisions to be satisfied before revenue is recognized. We recognize revenue on product sales to channel partners, including resellers, distributors or value-added solution providers at the time of sale when the channel partners have economic substance apart from Xylem and Xylem has completed its obligations related to the sale. Revenue from the rental of equipment is recognized over the rental period. Service revenue is recognized as services are performed.

For agreements that contain multiple deliverables, we recognize revenue based on the relative selling price if the deliverable has stand-alone value to the customer and, in arrangements that include a general right of return relative to the delivered element, performance of the undelivered element is considered probable and substantially in the Company’s control. The selling price for a deliverable is based on vendor-specific objective evidence of selling price (“VSOE”), if available, third-party evidence of selling price (“TPE”) if VSOE is not available, or best estimated selling price, if neither VSOE nor TPE is available.

The deliverables in our arrangements with multiple elements include various products and may include related services, such as installation and start-up services. Generally, these elements are satisfied within the same reporting period although certain contracts may be completed over 6 months . We allocate arrangement consideration based on the relative selling prices of the separate units of accounting determined in accordance with the hierarchy described above. For deliverables that are sold separately, we establish VSOE based on the price when the deliverable is sold separately. We establish TPE, generally for services, based on prices similarly situated customers pay for similar services from third-party vendors. For those deliverables for which we are unable to establish VSOE or TPE, we estimate the selling price considering various factors including market and pricing trends, geography, product customization, and profit objectives. Revenue for multiple element arrangements is recognized when the appropriate revenue recognition criteria for the individual deliverable have been satisfied.

Shipping and Handling Costs

Shipping and handling costs are recorded as a component of cost of revenue.

Share-Based Compensation

Share-based awards issued to employees and members of the Board of Directors include non-qualified stock options, restricted stock unit awards and performance share unit awards. Compensation costs resulting from share-based payment transactions are recognized primarily within selling, general and administrative expenses, at fair value over the requisite service period (typically three years) on a straight-line basis. The calculated compensation cost is adjusted based on an estimate of awards ultimately expected to vest. For performance awards, the calculated compensation cost is adjusted based on an estimate of awards ultimately expected to vest and

our assessment of the probable outcome of the performance condition.The fair value of a non-qualified stock option is determined on the date of grant using a binomial lattice pricing model incorporating multiple and variable assumptions over time, including assumptions such as employee exercise patterns, stock price volatility and changes in dividends. The fair value of restricted stock unit awards is determined using the closing price of our common stock on date of grant. The fair value of Return on Invested Capital ("ROIC") performance share units at 100% target is determined using the closing price of our common stock on date of grant. The fair value of Total Shareholder Return ("TSR") performance share units is calculated on the date of grant using a Monte Carlo simulation model utilizing several key assumptions, including expected Company and peer company share price volatility, correlation coefficients between peers, the risk-free rate of return, the expected dividend yield and other award design features.

Research and Development

We conduct research and development activities, which consist primarily of the development of new products, product applications, and manufacturing processes. These costs are charged to expense as incurred.

Exit and Disposal Costs

We periodically initiate management-approved restructuring activities to achieve cost savings through reduced operational redundancies and to position ourselves strategically in the market in response to prevailing economic conditions and associated customer demand. Costs associated with restructuring actions can include severance, infrastructure charges to vacate facilities or consolidate operations, contract termination costs and other related charges. For involuntary separation plans, a liability is recognized when it is probable and reasonably estimable. For voluntary separation plans, a liability is recognized when the employee irrevocably accepts the voluntary termination. For one-time termination benefits, such as additional severance pay or benefit payouts, and other exit costs, such as lease termination costs, the liability is measured and recognized initially at fair value in the period in which the liability is incurred, with subsequent changes to the liability recognized as adjustments in the period of change.

Deferred Financing Costs

Deferred financing costs represent costs incurred in conjunction with our debt financing activities and are capitalized in long-term debt and amortized over the life of the related financing arrangements. If the debt is retired early, the related unamortized deferred financing costs are written off in the period the debt is retired and are recorded in the results of operations under the caption “interest expense.”

Income Taxes

Income taxes are calculated using the asset and liability method. Deferred tax assets and liabilities are determined based on the estimated future tax effects of temporary differences between the financial statement carrying amounts and the tax bases of assets and liabilities, as measured by the current enacted tax rates.

We maintain valuation allowances when it is more likely than not that all or a portion of a deferred asset will not be realized. The valuation allowance is intended in part to provide for the uncertainty regarding the ultimate utilization of our U.S. capital loss carryforwards, U.S. foreign tax credit carryovers, and foreign net operating loss carryforwards. In determining whether a valuation allowance is warranted, we consider all positive and negative evidence and all sources of taxable income such as prior earnings history, expected future earnings, carryback and carryforward periods and tax strategies to estimate if sufficient future taxable income will be generated to realize the deferred tax asset. The assessment of the adequacy of our valuation allowance is based on our estimates of taxable income by jurisdiction in which we operate and the period over which our deferred tax assets will be recoverable. In the event that actual results differ from these estimates, or we adjust these estimates in future periods for current trends or expected changes in our estimating assumptions, we may need to modify the level of valuation allowance that could materially impact our business, financial condition and results of operations.

Due to U.S. Tax Reform, we have recorded provisional amounts of foreign withholding taxes and state income taxes on earnings that are expected to be repatriated to the U.S. parent. The Company intends to distribute a portion of the earnings taxed under the Tax Cuts and Jobs Act (the "Tax Act"). We have not recorded any deferred taxes on the amounts that the Company currently does not intend to distribute as the determination of any deferred taxes on this amount is not practicable.

Tax benefits are recognized for an uncertain tax position when, in management’s judgment, it is more likely than not that the position will be sustained upon examination by a taxing authority. For a tax position that meets the more-likely-than-not recognition threshold, the tax benefit is measured as the largest amount that is judged to have a greater than 50% likelihood of being realized upon ultimate settlement with a taxing authority. The liability

associated with unrecognized tax benefits is adjusted periodically due to changing circumstances and when new information becomes available. Such adjustments are recognized in the period in which they are identified. The effective tax rate includes the net impact of changes in the liability for unrecognized tax benefits and subsequent adjustments as considered appropriate by management. While it is often difficult to predict the final outcome or the timing of resolution of any particular tax matter, we believe our liability for unrecognized tax benefits is adequate. We classify interest relating to unrecognized tax benefits as a component of other non-operating (expense) income, net and tax penalties as a component of income tax expense in our Consolidated Income Statements.

Earnings Per Share

We present two calculations of earnings per share (“EPS”). “Basic” EPS equals net income divided by weighted average shares outstanding during the period. “Diluted” EPS equals net income divided by the sum of weighted average common shares outstanding during the period plus potentially dilutive shares. Potentially dilutive common shares that are anti-dilutive are excluded from diluted EPS.

Cash Equivalents

We consider all liquid investments purchased with an original maturity of three months or less to be cash equivalents.

Receivables and Allowance for Doubtful Accounts and Discounts

Receivables primarily comprise uncollected amounts owed to us from transactions with customers and are presented net of allowances for doubtful accounts, returns and early payment discounts.

Inventories

Inventories, which include the costs of material, labor and overhead, are stated at the lower of cost or net realizable value using the first in, first out ("FIFO") method. Estimated losses from obsolete and slow-moving inventories are recorded to reduce inventory values to their estimated net realizable value. Our manufacturing operations recognize costs of sales using standard costs with full overhead absorption, which generally approximates actual cost.

Property, Plant and Equipment

These assets are recorded at historical cost and are depreciated using the straight-line method of depreciation over the estimated useful lives as follows:



	Estimated Life
Buildings and improvements	5 to 40 years
Machinery and equipment	2 to 10 years
Furniture and fixtures	3 to 7 years
Equipment held for lease or rental	2 to 10 years

Leasehold improvements are depreciated over the shorter of their estimated useful life or the term of the lease. Costs related to maintenance and repairs that do not prolong the assets' useful lives are expensed as incurred.

Goodwill and Intangible Assets

Goodwill represents purchase consideration paid in a business combination that exceeds the values assigned to the net assets of acquired businesses. Intangible assets include customer relationships, proprietary technology,

brands and trademarks, patents, software and other intangible assets. Intangible assets with a finite life are amortized on a straight-line basis over an estimated economic useful life which ranges from 1 to 25 years and is included in cost of revenue or selling, general and administrative expense. Certain of our intangible assets, namely certain brands and trademarks, as well as FCC licenses, have an indefinite life and are not amortized.

Long-Lived Asset Impairment

Long-lived assets, including intangible assets with finite lives, are amortized and tested for impairment whenever events or changes in circumstances indicate their carrying value may not be recoverable. We assess the recoverability of long-lived assets based on the undiscounted future cash flow the assets are expected to generate and recognize an impairment loss when estimated undiscounted future cash flows expected to result from the use of the asset plus net proceeds expected from disposition of the asset, if any, are less than the carrying value of the asset. When an impairment is identified, we reduce the carrying amount of the asset to its estimated fair value based on a discounted cash flow approach or, when available and appropriate, to comparable market values.

Goodwill and indefinite-lived intangible assets are not amortized, but rather are tested for impairment annually (or more frequently if impairment indicators arise, such as changes to the reporting unit structure, significant adverse changes in the business climate or an adverse action or assessment by a regulator). We conduct our annual impairment testing on the first day of our fourth quarter. For goodwill, the estimated fair value of each reporting unit is compared to the carrying value of the net assets assigned to that reporting unit. If the estimated fair value of the reporting unit exceeds its carrying value, goodwill is not impaired. If the carrying value of the reporting unit exceeds its estimated fair value, then an impairment charge is recognized for that excess up to the amount of recorded goodwill. We estimate the fair value of our reporting units and indefinite-lived intangible assets using an income approach. Under the income approach, we estimate fair value based on the present value of estimated future cash flows discounted at an appropriate rate.

Product Warranties

We accrue for the estimated cost of product warranties at the time revenue is recognized and record it as a component of cost of revenue. Our product warranty liability reflects our best estimate of probable liability under the terms and conditions of our product warranties offered to customers. We estimate the liability based on our standard warranty terms, the historical frequency of claims and the cost to replace or repair our products under warranty. Factors that impact our warranty liability include the number of units sold, the length of warranty term, historical and anticipated rates of warranty claims and cost per claim. We also record a warranty liability for specific matters. We assess the adequacy of our recorded warranty liabilities quarterly and adjust amounts as necessary.

Postretirement Benefit Plans

The determination of defined benefit pension and postretirement plan obligations and their associated costs requires the use of actuarial computations to estimate participant plan benefits to which the employees will be entitled. The significant assumptions primarily relate to discount rates, expected long-term rates of return on plan assets, rate of future compensation increases, mortality, years of service and other factors. We develop each assumption using relevant company experience in conjunction with market-related data for each individual country in which such plans exist. All actuarial assumptions are reviewed annually with third-party consultants and adjusted as necessary. For the recognition of net periodic postretirement cost, the calculation of the expected return on plan assets is generally derived by applying the expected long-term rate of return on the market-related value of plan assets. The market-related value of plan assets is based on average asset values at the measurement date over the last five years. Actual results that differ from our assumptions are accumulated and amortized on a straight-line basis only to the extent they exceed 10% of the higher of the market-related value or the projected benefit obligation, over the average remaining service period of active participants, or for plans with all or substantially all inactive participants, over the average remaining life expectancy. The fair value of plan assets is determined based on market prices or estimated fair value at the measurement date.

We consider changes to a plan’s benefit formula that eliminate the accrual for future service but continue to allow for future salary increases (i.e. “soft freeze”) to be a curtailment.

Business Combinations

We allocate the purchase price of acquisitions to the tangible and intangible assets acquired, liabilities assumed, and non-controlling interests in the acquiree based on their estimated fair value at the acquisition date. The excess of the acquisition price over those estimated fair values is recorded as goodwill. Changes to the acquisition date provisional fair values prior to the expiration of the measurement period, a period not to exceed 12 months from date of acquisition, are recorded as an adjustment to the associated goodwill. Acquisition-related expenses and restructuring costs, if any, are recognized separately from the business combination and are expensed as incurred.

Derivative Financial Instruments

We record all derivatives on the balance sheet at fair value. The accounting for changes in the fair value of derivatives depends on whether we have elected to designate a derivative in a hedging relationship and apply hedge accounting and whether the hedging relationship has satisfied the criteria necessary to apply hedge accounting. Derivatives designated and qualifying as a hedge of the exposure to changes in the fair value of an asset, liability, or firm commitment attributable to a particular risk are considered fair value hedges. Derivatives designated and qualifying as a hedge of the exposure to variability in expected future cash flows, including forecasted transactions, are considered cash flow hedges. Derivatives may also be designated as hedges of the foreign currency exposure of a net investment in a foreign operation. Hedge accounting generally provides for the matching of the timing of gain or loss recognition on the hedging instrument with the recognition of the changes in the fair value of the hedged asset or liability that are attributable to the hedged risk in a fair value hedge or the earnings effect of the hedged forecasted transactions in a cash flow hedge. We may enter into derivative contracts that are intended to hedge certain risks economically, even though hedge accounting does not apply or we elect not to apply hedge accounting.

The effective portion of changes in the fair value of derivatives designated and that qualify as cash flow hedges of foreign exchange risk is recorded in other comprehensive income ("OCI") and is subsequently reclassified into either revenue or cost of revenue (hedge of sales classified into revenue and hedge of purchases classified into cost of revenue) in the period that the hedged forecasted transaction affects earnings. Any ineffective portion of the change in fair value of the derivative is recognized directly in selling, general and administrative expenses. Our policy is to de-designate cash flow hedges at the time forecasted transactions are recognized as assets or liabilities on a business unit’s balance sheet and report subsequent changes in fair value through selling, general and administrative expenses where the gain or loss due to movements in currency rates on the underlying asset or liability is revalued. If it becomes probable that the originally forecasted transaction will not occur, the gain or loss related to the hedge recorded within accumulated other comprehensive income ("AOCI") is immediately recognized into net income.

The effective portion of changes in the fair value of derivatives designated and that qualify as net investment hedges of foreign exchange risk is recorded in OCI. Amounts in AOCI are reclassified into earnings at the time the hedged net investment is sold or substantially liquidated. Effectiveness of derivatives designated as net investment hedges is assessed using the forward method. Any ineffective portion of the change in fair value of the derivative is recognized directly in selling, general and administrative expenses.

Commitments and Contingencies

We record accruals for commitments and loss contingencies for those which are both probable and for which the amount can be reasonably estimated. In addition, legal fees are accrued for cases where a loss is probable and the related fees can be reasonably estimated. Significant judgment is required to determine both probability and the estimated amount of loss. We review these accruals quarterly and adjust the accruals to reflect the impact of negotiations, settlements, rulings, advice of legal counsel, and other current information.

Accruals for environmental matters are recorded on a site-by-site basis when it is probable that a liability has been incurred and the amount of the liability can be reasonably estimated, based on current law and existing technologies. Our estimated liability is reduced to reflect the anticipated participation of other potentially responsible parties in those instances where it is probable that such parties are legally responsible and financially capable of paying their respective shares of the relevant costs. These accruals are reviewed quarterly and are adjusted as assessment and remediation efforts progress or as additional technical or legal information becomes available. Actual costs to be incurred at identified sites in future periods may vary from the estimates, given inherent uncertainties in evaluating environmental exposures. Accruals for environmental liabilities are primarily included in other non-current liabilities at undiscounted amounts and exclude claims for recoveries from insurance companies or other third parties.

Concentrations of Credit Risk

Financial instruments that potentially subject us to significant concentrations of credit risk consist principally of cash and cash equivalents, and accounts receivable from trade customers. We maintain cash and cash equivalents and derivative contracts with various financial institutions. These financial institutions are located in many different geographical regions, and our policy is designed to limit exposure with any one institution. As part of our cash and risk management processes, we perform periodic evaluations of the relative credit standing of the financial institutions. We have not sustained any material credit losses during the previous three years from instruments held at financial institutions. We may utilize forward contracts to protect against the effects of foreign currency fluctuations. Such contracts involve the risk of non-performance by the counterparty. Credit risk with respect to accounts receivable is generally diversified due to the large number of entities comprising our customer base and their dispersion across many different industries and geographic regions. We perform ongoing credit evaluations of the financial condition of our third-party distributors, resellers and other customers and require collateral, such as letters of credit and bank guarantees, in certain circumstances.

Substantially all of the cash and cash equivalents, including foreign cash balances, at December 31, 2017 and 2016 were uninsured. Foreign cash balances at December 31, 2017 and 2016 were $ 373 million and $ 242 million , respectively.

Fair Value Measurements

We determine fair value as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. We use a hierarchical structure to prioritize the inputs to valuation techniques used to measure fair value into three broad levels defined as follows:


•	Level 1 inputs are quoted prices (unadjusted) in active markets for identical assets or liabilities.

•

Level 2 inputs are other than quoted prices included within Level 1 that are observable for the asset or liability, either directly or indirectly. Level 2 inputs include quoted prices (in non-active markets or in active markets for similar assets or liabilities), inputs other than quoted prices that are observable, and inputs that are derived principally from or corroborated by observable market data by correlation or other means.


•	Level 3 inputs are unobservable inputs for the assets or liabilities.

The fair value hierarchy is based on maximizing the use of observable inputs and minimizing the use of unobservable inputs when measuring fair value. Classification within the fair value hierarchy is based on the lowest level input that is significant to the fair value measurement.

NAV Practical Expedient is the measurement of fair value using the net asset value ("NAV") per share (or its equivalent) as an alternative to the fair value hierarchy as discussed above.

Note 2 . Recently Issued Accounting Pronouncements

Pronouncements Not Yet Adopted

In February 2018, the Financial Accounting Standards Board (“FASB”) issued amended guidance on the reclassification of certain tax impacts from Accumulated Other Comprehensive Income ("AOCI"). The amendment allows a reclassification from accumulated other comprehensive income to retained earnings for stranded tax effects resulting from the Tax Act. The guidance also requires certain disclosures related to stranded tax effects. This guidance is effective for fiscal years beginning after December 15, 2018, including interim periods within those annual periods. Early adoption is permitted. The guidance may be applied either in the period of adoption or retrospectively to each period (or periods) in which the effect of the change in the U.S. federal corporate income tax rate in the Tax Act is recognized. We are evaluating the impact of the guidance on our financial condition and results of operations.

In August 2017, the FASB issued amended guidance on hedging activities. The amendment better aligns a company’s risk management activities and financial reporting for hedging relationships through changes to both the designation and measurement guidance for qualifying for hedging relationships and the presentation of hedge results. Specifically, the guidance:


(1)	Eliminates the concept of recognizing periodic hedge ineffectiveness for cash flow and net investment hedges


(2)	Eliminates the benchmark interest rate concept of variable - rate instruments in cash flow hedges and allows companies to designate the contractually specified interest rate as the hedged risk


(3)	Requires a company to present the earnings effect of the hedging instrument in the same income statement line item in which the earnings effect of the hedged item is reported


(4)	Provides the ability to perform subsequent hedge effectiveness tests qualitatively

This guidance is effective for fiscal years beginning after December 15, 2018, including interim periods within those annual periods. Early adoption is permitted with the effect of adoption reflected as of the beginning of the fiscal year of adoption. For cash flow and net investment hedges existing at the date of adoption, a cumulative-effect adjustment related to eliminating the separate measurement of ineffectiveness is required. Other presentation and disclosure guidance is required only prospectively. We are evaluating the impact of the guidance on our financial condition and results of operations.

In March 2017, the FASB issued amended guidance on presentation of net periodic benefit costs. The amendment requires that an employer report the service cost component in the same line item or items as other compensation costs arising from services rendered by the pertinent employees during the period. The other components are required to be presented in the income statement separately and outside a subtotal of income from operations, if one is presented. The amendment also requires entities to disclose the income statement lines that contain the other components if they are not appropriately described. This guidance is effective retrospectively for periods beginning after December 15, 2017, including interim periods within those annual periods. Early adoption is permitted. The adoption of this guidance is expected to impact the presentation between operating income and other non operating income within Xylem's Consolidated Income Statement but is not expected to have a material impact on our consolidated financial condition or results of operations.

In June 2016, the FASB issued guidance amending the accounting for the impairment of financial instruments, including trade receivables. Under current guidance, credit losses are recognized when the applicable losses are probable of occurring and this assessment is based on past events and current conditions. The amended guidance eliminates the “probable” threshold and requires an entity to use a broader range of information, including forecast information when estimating expected credit losses. Generally, this should result in a more timely recognition of credit losses. This guidance is effective for interim and annual periods beginning after December 15, 2019 with early adoption permitted for interim and annual periods beginning after December 15, 2018. The requirements of the amended guidance should be applied using a modified retrospective approach except for debt securities, which require a prospective transition approach. We are evaluating the impact of the guidance on our financial condition and results of operations.

In February 2016, the FASB issued guidance amending the accounting for leases. Specifically, the amended guidance requires all lessees to record a lease liability at lease inception, with a corresponding right of use asset, except for short-term leases. Lessor accounting is not fundamentally changed. This amended guidance is effective for interim and annual periods beginning after December 15, 2018 using a modified retrospective approach. Early adoption is permitted. We are evaluating the impact of the guidance on our financial condition and results of operations.

In May 2014, the FASB issued guidance on recognizing revenue from contracts with customers. The guidance outlines a single comprehensive model to use in accounting for revenue arising from contracts with customers and supersedes most current revenue recognition guidance, including industry-specific guidance. The core principle of the model is that an entity recognizes revenue to portray the transfer of goods and services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. The standard also expands disclosure requirements regarding revenue recognition. This guidance is effective for interim and annual reporting periods beginning after December 15, 2017 and may be applied retrospectively to each prior period presented or using a modified retrospective approach with the cumulative effect recognized as of the date of initial application. Early adoption is permitted for interim and annual reporting periods beginning after December 15, 2016. We adopted this guidance effective January 1, 2018 using the modified retrospective approach. The adoption of this guidance did not have a material impact on our financial condition or results of operations.

Recently Adopted Pronouncements

In May 2017, the FASB issued guidance, which amends the scope of modification accounting guidance for share-based payment arrangements. The guidance outlines the types of changes to the terms or conditions of share-based payment arrangements that would require the use of modification accounting. Specifically, modification accounting would not apply if the fair value, vesting conditions, and classification of the award as equity or liability are the same immediately before and after the modification. This guidance is effective prospectively for interim and annual reporting periods beginning December 15, 2017 and early adoption is permitted. We elected to early adopt

this guidance effective the second quarter of 2017. The adoption of this guidance did not impact our financial condition or results from operations.

In January 2017, the FASB issued guidance amending the impairment testing of goodwill. Under current guidance, the testing of goodwill for impairment is performed at least annually using a two-step test. Step one involves comparing the fair value of a “reporting unit” to its carrying amount. If the applicable book value exceeds the reporting unit’s fair value then step two must be performed. Step two involves comparing the fair value of the reporting unit’s goodwill to the applicable carrying amount of the asset and recognizing an impairment charge equal to the amount by which the carrying amount of the goodwill exceeds its implied fair value. The amended guidance eliminates step two of the impairment test and allows an entity to record an impairment charge equal to the amount that the carrying amount of the applicable reporting unit exceeds its fair value, up to the value of the recorded goodwill. This guidance is effective prospectively for interim and annual goodwill impairment tests beginning after December 15, 2019 with early adoption permitted for interim or annual tests after January 1, 2017. We elected to early adopt this guidance effective the first quarter of 2017. The adoption of this guidance did not impact our financial condition or results of operations.

In October 2016, the FASB issued guidance amending the accounting for income taxes. Under current guidance the recognition of current and deferred income taxes for an intra-entity asset transfer is prohibited until the asset has been sold to an outside party. The amended guidance eliminates the prohibition against immediate recognition of current and deferred income tax amounts associated with intra-entity transfers of assets other than inventory. This guidance is effective for interim and annual periods beginning after December 15, 2017 with early adoption permitted as of the beginning of an annual reporting period for which financial statements (interim or annual) have not been issued or made available for issuance. The requirements of the amended guidance should be applied on a modified retrospective basis through a cumulative-effect adjustment directly to retained earnings as of the beginning of the period of adoption. We elected to early adopt this guidance effective the first quarter of 2017. As a result of adopting the amended guidance, prepaid tax assets were reduced by $ 14 million , long-term deferred tax assets increased $ 3 million , and accrued taxes were reduced by $ 4 million . The net impact of these adjustments on retained earnings was a decrease of $ 7 million .

In July 2015, the FASB issued guidance regarding simplifying the measurement of inventory. Under prior guidance, inventory is measured at the lower of cost or market, where market is defined as replacement cost, with a ceiling of net realizable value and a floor of net realizable value less a normal profit margin. The amended guidance requires the measurement of inventory at the lower of cost and net realizable value. Net realizable value is the estimated selling prices in the ordinary course of business, less reasonably predictable costs of completion, disposal, and transportation. This guidance is effective prospectively for interim and annual periods beginning after December 15, 2016 and early application is permitted. We adopted this guidance effective the first quarter of 2017. The adoption of this guidance did not impact our financial condition or results of operations.

In March 2016, the FASB issued an update on accounting for share-based payments. The guidance simplifies several aspects of the accounting for employee share-based payment transactions, including the accounting for income taxes, forfeitures, and statutory tax withholding requirements, as well as classification of excess tax benefits in the Consolidated Statements of Cash Flows. This standard is effective for annual reporting periods beginning after December 15, 2016. The Company elected to early adopt this standard in the quarter ended June 30, 2016 retroactively to January 1, 2016. The impact of the early adoption resulted in the following:


•	The Company recorded tax benefits of $ 3 million within income tax expense for the year ended December 31, 2016 related to the excess tax benefit on share-based awards. Prior to adoption this amount would have been recorded as an increase of capital in excess of par value. This change could create volatility in the Company's effective tax rate.


•	The Company no longer reflects the cash received from the excess tax benefit within cash flows from financing activities but instead now reflects this benefit within cash flows from operating activities in the Consolidated Statements of Cash Flows. The Company elected to apply this change in presentation prospectively and thus prior periods have not been adjusted.


•	The Company elected not to change its policy on accounting for forfeitures and continues to estimate the total number of awards for which the requisite service period will not be rendered.


•	At this time, the Company has not changed its policy on statutory withholding requirements and will continue to allow the employee to withhold up to the Company's minimum statutory withholding requirements.


•	The Company excluded the excess tax benefits from the assumed proceeds available to repurchase shares in the computation of our diluted earnings per share for the year ended December 31, 2016. This increased diluted weighted average common shares outstanding by less than 300,000 shares for the aforementioned period.

In March 2016, the FASB amended the guidance regarding the use of the equity method to record certain investments. Under current guidance, if an investor increases its level of ownership interest in a company and consequently qualifies for the equity method, the investor must retroactively adjust its investment, results of operations and retained earnings to reflect balances that would have arisen if the equity method had been in effect during all previous periods that the investment was held. The amended guidance eliminates the need to retroactively adjust balances and instead allows for the prospective application of the equity method. This guidance is effective prospectively for interim and annual reporting periods beginning after December 15, 2016. We elected to early adopt this guidance effective January 2016. The adoption of this guidance did not impact our financial condition or results of operations.

In March 2016, in response to inconsistency in practice, the FASB issued guidance regarding the ability to maintain hedge accounting for a derivative instruments when one party to the instrument has been replaced by a new party (“a novation”). The new guidance states that a novation does not preclude the continued application of hedge accounting to a derivative assuming all other hedge accounting criteria continue to be met. This guidance is effective using either a prospective or a modified retrospective approach, for interim and annual reporting periods beginning after December 15, 2016. We elected to early adopt this guidance on a prospective basis effective January 2016. The adoption of this guidance did not impact our financial condition or results of operations.

In March 2016, the FASB issued guidance clarifying what steps need to be followed when evaluating if call or put options are not clearly and closely related to their debt hosts, and therefore must be accounted for as separate derivatives. The guidance prescribes a four step process to assess whether an event that triggers the ability to exercise a call or put option is clearly and closely related to the debt host. The four step decision sequence requires an entity to consider whether (1) the payoff is adjusted based on changes in an index; (2) the payoff is indexed to an underlying other than interest rates or credit risk; (3) the debt involves a substantial premium or discount; and (4) the call or put option is contingently exercisable. This guidance is effective using a modified retrospective approach, for interim and annual reporting periods beginning after December 15, 2016. We elected to early adopt this guidance effective January 2016. The adoption of this guidance did not impact our financial condition or results of operations.

Note 3 . Acquisitions and Divestitures

Pure Technologies

On January 31, 2018, we acquired all the issued and outstanding shares of Pure Technologies Ltd. (“Pure”), a leader in intelligent leak detection and condition assessment solutions for water distribution networks. In connection with this acquisition we had cash disbursements of approximately $ 415 million , net of cash received. Pure, headquartered in Calgary, Canada, has approximately 500 employees and annual revenue in accordance with International Financial Reporting Standards of approximately $ 100 million . Due to the timing of this transaction, purchase accounting has just commenced and is preliminary.

2017 Acquisitions and Divestitures

Acquisition Activity

During 2017 we spent approximately $ 33 million on acquisition activity, including the acquisition of EmNet LLC (“EmNet”), a developer of software and data analytics solutions for municipalities.

Divestitures

On October 31, 2017, we divested our Flowtronex and Water Equipment Technologies (WET) businesses for $ 6 M . The sale resulted in a gain of approximately $ 1 million , which is reflected in gain from sale of business in our Condensed Consolidated Income Statement. The business, which was part of our Applied Water segment, provided turf and reverse osmosis packages to customers in the agricultural and industrial sectors. The business reported approximately $ 9 M of revenue in the first 10 months of the year.

On February 17, 2017, we divested our United Kingdom and Poland based membranes business for approximately $ 10 million . The sale resulted in a gain of $ 5 million , which is reflected in gain from sale of business in our Condensed Consolidated Income Statement. The business, which was part of our Applied Water segment, provided

membrane filtration products primarily to customers in the municipal water and industrial sectors. The business reported 2016 annual revenue of approximately $ 8 million .

Assets Held for Sale

During the fourth quarter of 2017 two of our businesses qualified as held for sale treatment. Accordingly an estimated loss of $ 16 million was recognized.

2016 Acquisition

Sensus Worldwide Limited

On October 31, 2016, we acquired all of the outstanding equity interests of Sensus Worldwide Limited (other than Sensus Industries Limited) (“Sensus”) effective October 31, 2016 for $ 1,766 million ( $ 1,710 million net of cash acquired), including a $ 6 million payment in 2017 for a working capital adjustment. Sensus develops advanced technology solutions that enable intelligent use and conservation of critical water and energy resources. Sensus' major products include smart metering, networked communications, measurement and control technologies, software and services including cloud-based analytics, remote monitoring and data management . The Company acquired Sensus because it believes that, within its market category, its products have superior qualities and usefulness to customers. The Company also acquired Sensus on the strength of its developed technology that we plan to leverage across our existing base of products and customers.

Acquisition costs of $ 19 million were reflected as a component of selling, general and administrative expenses in our Consolidated Income Statements.

Sensus results of operations were consolidated with the Company effective November 1, 2016 and it is part of the Measurement & Control Solutions segment. Refer to Note 20 "Segment and Geographic Data" for Measurement & Control Solutions segment information.

The Sensus purchase price allocation as of October 31, 2016 is shown in the following table.



(in millions)	Amount
Cash	$	56
Receivables	104
Inventories	79
Prepaid and other current assets	19
Property, plant and equipment	176
Intangible assets	782
Other long-term assets	5
Accounts payable	( 69		)
Accrued and other current liabilities	( 90		)
Deferred income tax liabilities	( 198		)
Accrued post retirement benefits	( 84		)
Other non-current accrued liabilities	( 60		)
Total identifiable net assets	720

Goodwill	1,063
Non-controlling interest	( 17		)
Total consideration	$	1,766

In the third quarter of 2017 we finalized the Sensus purchase price allocation. The fair values of Sensus assets and liabilities were determined based on estimates and assumptions which management believes are reasonable.

Goodwill arising from the acquisition consists largely of synergies and economies of scale expected from combining the operations of Sensus and Xylem. All of the goodwill was assigned to the Measurement & Control Solutions segment and is not deductible for tax purposes.

The estimate of the fair value of Sensus identifiable intangible assets was determined primarily using the “income approach,” which requires a forecast of all of the expected future cash flows either through the use of the multi-period excess earnings method or the relief-from-royalty method. Some of the more significant assumptions inherent in the development of intangible asset values include: the amount and timing of projected future cash flows, the discount rate selected to measure the risks inherent in the future cash flows, the assessment of the intangible asset’s life cycle, as well as other factors. The following table summarizes key information underlying identifiable intangible assets related to the Sensus acquisition:



Category	Life	Amount (in millions)
Customer and Distributor Relationships	2 - 18 years	$	543
Tradenames	10 - 25 years	98
Internally Developed Network Software	7 years	60
FCC Licenses	Indefinite lived	24
Technology	5 - 15 years	39
Other	1 - 16 years	18
Total		$	782

The following table summarizes, on an unaudited proforma basis, the condensed combined results of operations of the Company for the years ended December 31, 2016 and 2015 assuming the acquisition of Sensus was made on January 1, 2015.



	Year Ended December 31,
(in millions)	2016		2015
Revenue	$	4,528	$	4,507
Net income	$	286	$	423

The foregoing unaudited proforma results are for informational purposes only and are not necessarily indicative of the actual results of operations that might have occurred had the acquisition occurred on January 1, 2015, nor are they necessarily indicative of future results. The pro forma financial information includes the impact of purchase accounting and other nonrecurring items directly attributable to the acquisition, which include:


•	Adjustments to revenue resulting from the valuation of the acquired deferred revenue balance to fair value as part of purchase accounting


•	Amortization expense of acquired intangibles


•	Amortization of the fair value step-up in inventory


•	Adjustments to the depreciation of property, plant and equipment reflecting the impact of the calculated fair value of those assets in accordance with purchase accounting


•	Amortization of the fair value adjustment for warranty liabilities


•	Adjustments to interest expense to remove historical Sensus interest costs and reflect Xylem's current debt profile


•	The related tax impact of the above referenced adjustments

The pro forma results do not include any cost savings or operational synergies that may be generated or realized due to the acquisition of Sensus. Additionally, the pro forma results for the 2016 and 2015 both include the operating results for the three months ended March 31, 2016 due to the use of Sensus’ annual statement of operations for the fiscal year-ended March 31, 2016 in the twelve months ended December 31, 2015 pro forma numbers. This practice results in the recognition of a $ 16 million tax valuation release and a $ 27 million reduction to warranty expense in both the 2016 and 2015 pro forma results. Additionally, the pro forma results for 2015 include a tax valuation release of $ 64 million .

For the two month period ended December 31, 2016 Sensus had revenue and net loss of $ 132 million and $ 13 million, respectively.

Visenti Pte. Ltd

On October 18, 2016, we acquired Visenti Pte. Ltd. (“Visenti”), a smart water analytics company focused on leak detection and pressure monitoring solutions to help water utilities manage their water networks for $ 8 million . Visenti, a privately-owned company headquartered in Singapore, has approximately 25 employees. Our consolidated financial statements include Visenti's results of operations prospectively from October 18, 2016 within the Measurement & Control Solutions segment.

Tideland Signal Corporation

On February 1, 2016, we acquired Tideland Signal Corporation (“Tideland”), a leading producer of analytics solutions in the coastal and ocean management sectors, for $ 70 million . Tideland, a privately-owned company headquartered in Texas, has approximately 160 employees. Our consolidated financial statements include Tideland's results of operations prospectively from February 1, 2016 within the Water Infrastructure segment.

2015 Acquisition and Divestitures

On October 22, 2015, we acquired substantially all of the assets of Hypack, Inc. ("Hypack"), a leading provider of hydrographic software worldwide, for approximately $ 18 million . Hypack, a privately-owned company headquartered in Middletown, Connecticut, has approximately 30 employees and annual revenue of approximately $ 8 million . Our consolidated financial statements include Hypack's results of operations prospectively from October 22, 2015 within the Water Infrastructure segment.

During 2015, we divested two businesses within our Water Infrastructure segment for $ 1 million , which were not material, individually or in the aggregate, to our results of operations or financial position. The sales resulted in a gain of $ 9 million , reflected in gain from sale of business in our Consolidated Income Statement.

Note 4. Restructuring and Asset Impairment Charges

From time to time, the Company will incur costs related to restructuring actions in order to optimize our cost base and more strategically position ourselves based on the economic environment and customer demand. During 2017 , 2016 and 2015, the costs incurred primarily relate to an effort to reposition our European and North American businesses to optimize our cost structure and improve our operational efficiency and effectiveness. The charges included the reduction of headcount and consolidation of facilities within our Applied Water,Water Infrastructure, and Measurement & Control Solutions segments, as well as Corporate headcount reductions. The components of restructuring charges incurred during each of the previous three years ended are presented below.

Reconciliations between taxes at the U.S. federal income tax rate and taxes at our effective income tax rate on earnings before income taxes are as follows:



	Year Ended December 31,
	2017		2016		2015
Tax provision at U.S. statutory rate	35.0	%	35.0	%	35.0	%
Increase (decrease) in tax rate resulting from:
State income taxes	1.6		0.8		1.0
Settlements of tax examinations	1.6		( 6.4	)	0.5
Valuation allowance	3.3		18.5		8.6
Tax exempt interest	( 10.6	)	( 14.3	)	( 13.1	)

Rate change	( 22.9	)	—		—
Effective income tax rate	29.2	%	23.5	%	15.6	%

We operate under tax incentives, which are effective January 2013 through December 2023 and may be extended if certain additional requirements are satisfied. The tax incentives are conditional upon our meeting and maintaining certain employment thresholds. The inability to meet the thresholds would have a prospective impact and at this time we continue to believe we will meet the requirements.

Deferred tax assets and liabilities are determined based on temporary differences between the financial reporting and tax bases of assets and liabilities, applying enacted tax rates in effect for the year in which we expect the differences will reverse.

The following is a summary of the components of the net deferred tax assets and liabilities recognized in the Consolidated Balance Sheets:



	December 31,
(in millions)	2017			2016
Deferred tax assets:
Employee benefits	$	108		$	126
Accrued expenses	34			53
Loss and other tax credit carryforwards	419			387
Inventory	8			6
Other	24			—
	593			572
Valuation allowance	( 350		)	( 311		)
Net deferred tax asset	$	243		$	261
Deferred tax liabilities:
Intangibles	$	300		$	434
Investment in foreign subsidiaries	20			4
Property, plant, and equipment	57			61
Other	49			48
Total deferred tax liabilities	$	426		$	547

Management assesses the available positive and negative evidence to estimate if sufficient future taxable income will be generated to realize existing deferred tax assets. On the basis of this evaluation, as of December 31, 2017 , a valuation allowance of $ 350 million has been established to reduce the deferred income tax asset related to certain U.S. and foreign net operating losses and U.S. and foreign capital loss carryforwards.

A reconciliation of our valuation allowance on deferred tax assets is as follows:



(in millions)	2017			2016			2015
Valuation allowance — January 1	$	311		$	248		$	427
Change in assessment (a)	( 28		)	17			( 5		)
Current year operations	48			38			39
Foreign currency and other (b)	19			( 32		)	( 213		)
Acquisitions	—			40			—
Valuation allowance — December 31	$	350		$	311		$	248


(a)	Decrease in assessment in 2017 is primarily attributable to Foreign Tax Credit utilization resulting from the Tax Act. Increase in assessment in 2016 is primarily attributable to Foreign Tax Credits resulting from additional indebtedness from the Sensus acquisition.

(b) Included in foreign currency and other in 2015 is the reduction of a net operating loss that was subject to a valuation allowance of $ 176 million .

Deferred taxes are classified net of unrecognized tax benefits in the Consolidated Balance Sheets as follows:



	December 31,
(in millions)	2017			2016

The Company intends to distribute a portion of the earnings taxed under the Tax Act and, as of December 31, 2017 , has provided a provisional deferred tax liability of $ 20 million for foreign withholding taxes and state income taxes on $ 769 million of earnings expected to be repatriated to the U.S. parent. The Company currently does not intend to distribute approximately $ 2 billion taxed under the Tax Act, and has not recorded any deferred taxes related to such amounts as the determination of the amount is not practicable.

Unrecognized Tax Benefits

We recognize tax benefits from uncertain tax positions only if it is more likely than not that the tax position will be sustained on examination by the taxing authorities, based on the technical merits of the position. The tax benefits recognized in the consolidated financial statements from such positions are measured based on the largest benefit that has a greater than 50% likelihood of being realized upon ultimate settlement. A reconciliation of the beginning and ending amount of unrecognized tax benefits is as follows:



(in millions)	2017		2016			2015
Unrecognized tax benefits — January 1	$	67	$	47		$	44
Current year tax positions	56		12			4

Acquisitions	—		30			—
Settlements	—		—			( 2		)
Unrecognized tax benefits — December 31	$	130	$	67		$	47

The amount of unrecognized tax benefits at December 31, 2017 which, if ultimately recognized, will reduce our annual effective tax rate is $ 130 million . We do not believe that the unrecognized tax benefits will significantly change within the next 12 months.

The following table summarizes our earliest open tax years by major jurisdiction:

Luxembourg		2014
Sweden		2012
Germany		2010
United Kingdom		2010
United States		2014
Switzerland		2012

We classify interest relating to unrecognized tax benefits as a component of other non-operating (expense) income, net and tax penalties as a component of income tax expense in our Consolidated Income Statements. The amount of accrued interest relating to unrecognized tax benefits as of December 31, 2017 and 2016 was $ 4 million .

Tax Act

interest expense; and (8) changing rules related to uses and limitations of net operating loss carryforwards created in tax years beginning after December 31, 2017.

The SEC staff issued SAB118, which expresses views of the staff regarding application of ASC740 in the reporting period that includes December 22, 2017. SAB118 provides a measurement period that should not extend beyond one year from the Tax Act enactment date for companies to complete the accounting under ASC 740. In accordance with SAB118, a company must reflect the income tax effects of those aspects of the Act for which the accounting under ASC740 is complete. To the extent that a company’s accounting for certain income tax effects of the Tax Act is incomplete but it is able to record a reasonable estimate, it must record a provisional estimate in the financial statements. If a company cannot determine a provisional estimate to be included in the financial statements, it should continue to apply ASC740 on the basis of the provisions of the tax laws that were in effect immediately before the enactment of the Tax Act.

We are still performing our accounting for the tax effects of the Tax Act because all the necessary information is not currently available, prepared, or analyzed. As permitted by SAB118, we have made a reasonable estimate of the effects of the Tax Act on our financial results (see below). As we perform our analysis of the accounting for the tax effects of enactment of the Tax Act, we will recognize additional provisional amounts or adjustments to provisional amounts as discrete items in the periods in which the respective analyses are performed.

In connection with our initial analysis of the impact of the Tax Act, we have recorded a provisional tax expense of $ 46 million as a discrete item. This net income tax expense primarily consists of a provisional tax benefit for the corporate tax rate reduction of $ 107 million and a provisional tax expense for the repatriation transition tax of $ 153 million . For various reasons that are discussed in detail below, we have completed our accounting for the income tax effects of certain elements of the Tax Act, and therefore, have recorded provisional estimates related to these items. For certain items, a provisional estimate could not be determined, and therefore, we have continued accounting for them in accordance with ASC 740 on the basis of the tax laws in effect before the Tax Act.

Our accounting for the following elements of the Tax Act is incomplete. However, we were able to make reasonable estimates for these elements and, therefore, recorded provisional adjustments as follows:

Reduction of U.S. federal corporate tax rate: The Tax Act reduces the corporate tax rate to 21 percent, effective January 1, 2018. Consequently, we have adjusted our deferred taxes to account for the rate change, and have recorded a provisional decrease related to net deferred tax liabilities (DTLs) of $ 107 million , respectively, with a corresponding net adjustment to deferred tax benefit for the year ended December 31, 2017. Additional work is necessary for a more detailed analysis of our deferred tax assets and liabilities.

Deemed Repatriation Transition Tax : The Deemed Repatriation Transition Tax (Transition Tax) is a tax on previously untaxed accumulated and current earnings and profits (E&P) of certain foreign subsidiaries. To determine the amount of the Transition Tax, we determined in addition to other factors, the amount of post 1986 E&P of the relevant subsidiaries, as well as the amount of the non-U.S. income taxes paid on such earnings. We are able to make a reasonable estimate of the Transition Tax and recorded a provisional Transition Tax liability of $ 153 million . This provisional amount may materially change due to additional analysis, changes in interpretations and assumptions the Company has made, additional regulatory guidance that may be issued, and actions the Company may take as a result of the Tax Act.

Our accounting for the following elements of the Tax Act is incomplete, and we have not yet been able to make reasonable estimates of the effects. Therefore, no provisional adjustments were recorded as of December 31, 2017.

Global intangible low taxed income (GILTI): The Tax Act creates a new requirement that certain income (i.e., GILTI) earned by controlled foreign corporations (CFCs) must be included currently in the gross income of the CFCs’ U.S. shareholder. GILTI is the excess of the shareholder’s “net CFC tested income” over the net deemed tangible income return, which is currently defined as the excess of (1) 10 percent of the aggregate of the U.S. shareholder’s pro rata share of the qualified business asset investment of each CFC with respect to which it is a U.S. shareholder over (2) the amount of certain interest expense taken into account in the determination of net CFC-tested income.

Because of the complexity of the new GILTI tax rules, we are continuing to evaluate this provision of the Tax Act and the application of ASC740. According to clarifications from FASB, we are allowed to make an accounting policy choice of either (1) treating taxes due on future U.S. inclusions in taxable income related to GILTI as a current period-expense when incurred (the “period cost method”) or (2) factoring such amounts into measurement of deferred taxes (the “deferred method”). Our selection of an accounting policy with respect to the new GILTI tax rules will depend, in part, on analyzing our global income to determine any future U.S. inclusions in taxable income related to GILTI and the related impact. Because whether we expect to have future U.S. inclusions in taxable

income related to GILTI depends on not only our current structure and estimated future results of global operations but also our intent and ability to modify our structure and/or our business, we are not yet able to reasonably estimate the effects of this provision of the Tax Act. Therefore, as of December 31, 2017, we have not made any adjustments related to potential GILTI tax in our financial statements and have not yet made a policy decision regarding whether to record deferred taxes on GILTI.

Note 7. Earnings Per Share

(a)	Restricted stock awards containing rights to non-forfeitable dividends that participate in undistributed earnings with common shareholders are considered participating securities for purposes of computing earnings per share.

(b) Incremental shares from stock options, restricted stock units and performance share units are computed by the treasury stock method. The weighted average shares listed below were not included in the computation of diluted earnings per share because to do so would have been anti-dilutive for the periods presented or were otherwise excluded under the treasury stock method. The treasury stock method calculates dilution assuming the exercise of all in-the-money options and vesting of restricted stock units and performance share units, reduced by the repurchase of shares with the proceeds from the assumed exercises and unrecognized compensation expense for outstanding awards. Performance share units are included in the treasury stock calculation of diluted earnings per share based upon achievement of underlying performance and market conditions at the end of the reporting period, as applicable. See Note 15 , "Stock-Based Compensation Plans" for further detail on the performance share units.



	Year Ended December 31,

(a)	On February 1, 2016, we acquired Tideland and recorded $ 38 million of goodwill. On October 18, 2016, we acquired Visenti and recorded $ 6 million of goodwill. On October 31, 2016, we acquired Sensus and recorded $ 1,062 million of goodwill. Refer to Note 3 , "Acquisitions and Divestitures" for additional information.

During the fourth quarter of 2017, we performed our annual impairment assessment and determined that the estimated fair values of our goodwill reporting units were in excess of each of their carrying values. However, future goodwill impairment tests could result in a charge to earnings. We will continue to evaluate goodwill on an annual basis as of the beginning of our fourth quarter and whenever events and changes in circumstances indicate there may be a potential impairment.

Other Intangible Assets

Information regarding our other intangible assets is as follows:



(in millions)	December 31, 2017							December 31, 2016

Other intangibles	$	1,671	$	( 503	)	$	1,168	$	1,584	$	( 383	)	$	1,201

We determined that no impairment of the indefinite-lived intangibles existed as of the measurement date of our annual impairment assessment in 2017 or 2016. Future impairment tests could result in a charge to earnings. We will continue to evaluate the indefinite-lived intangible assets on an annual basis as of the beginning of our fourth quarter and whenever events and changes in circumstances indicate there may be a potential impairment.

Customer and distributor relationships, proprietary technology and patents, trademarks, software and other are amortized over weighted average lives of approximately 14 years, 16 years, 12 years, 5 years and 5 years, respectively.

Total amortization expense for intangible assets was $ 125 million , $ 64 million , and $ 45 million for 2017 , 2016 and 2015 , respectively.

Estimated amortization expense for each of the five succeeding years is as follows:



(in millions)
2018	$	121
2019	116
2020	107
2021	91
2022	86

During the first quarter of 2017 we determined that the intended use of a finite lived trade name within our Applied Water segment had changed. Accordingly we recorded a $ 4 million impairment charge. The charge was calculated using the income approach, which is considered a Level 3 input for fair value measurement, and is reflected in "Restructuring and asset impairment charges" in our Consolidated income Statements.

Note 11. Derivative Financial Instruments

Risk Management Objective of Using Derivatives

We are exposed to certain risks arising from both our business operations and economic conditions, and principally manage our exposures to these risks through management of our core business activities. Certain of our foreign operations expose us to fluctuations of interest rates and exchange rates that may impact revenue, expenses, cash receipts, cash payments, and the value of our stockholders' equity. We enter into derivative financial instruments to protect the value or fix the amount of certain cash flows in terms of the functional currency of the business unit with that exposure and reduce the volatility in stockholders' equity.

Cash Flow Hedges of Foreign Exchange Risk

We are exposed to fluctuations in various foreign currencies against our functional currencies. We use foreign currency derivatives, including currency forward agreements, to manage our exposure to fluctuations in the various exchange rates. Currency forward agreements involve fixing the foreign currency exchange rate for delivery of a specified amount of foreign currency on a specified date.

Certain business units with exposure to foreign currency exchange risks have designated certain currency forward agreements as cash flow hedges of forecasted intercompany inventory purchases and sales. Our principal currency exposures relate to the Euro, Swedish Krona, British Pound, Canadian Dollar, Polish Zloty, and Australian Dollar. We had foreign exchange contracts with purchase notional amounts totaling $ 455 million as of December 31, 2017. As of December 31, 2017, our most significant foreign currency derivatives included contracts to purchase Swedish Krona and sell Euro, sell U.S. Dollar and purchase Euro, sell British Pound and purchase Euro, purchase Polish Zloty and sell Euro, purchase U.S. Dollar and sell Canadian Dollar and to sell Canadian Dollar and purchase Euro. The purchase notional amounts associated with these currency derivatives were $ 149 million , $ 147 million , $ 66 million , $ 34 million , $ 28 million and $ 25 million , respectively. As of December 31, 2016 we did not hold any foreign exchange contracts.

Hedges of Net Investments in Foreign Operations

We are exposed to changes in foreign currencies impacting our net investments held in foreign subsidiaries.

Cross Currency Swaps

Beginning in 2015, we entered into cross currency swaps to manage our exposure to fluctuations in the Euro-U.S. Dollar exchange rate. The total notional amount of derivative instruments designated as net investment hedges was $ 446 million and $ 391 million as of December 31, 2017 and 2016, respectively.

Foreign Currency Denominated Debt

On March 11, 2016, we issued 2.250 % Senior Notes of € 500 million aggregate principal amount due March 2023. We designated the entirety of the outstanding balance, or $ 592 million and $ 517 million as of December 31, 2017 and 2016, respectively, net of unamortized discount, as a hedge of a net investment in certain foreign subsidiaries.

Forward Contracts

On September 23, 2016, we entered into forward contacts with a total notional amount of € 300 million to manage our exposure to fluctuations in the Euro-U.S. Dollar exchange rate. The contracts were designated as net investment hedges and were settled in 2016.

The table below presents the effect of our derivative financial instruments on the Consolidated Income Statements and Consolidated Statements of Comprehensive Income.

(a)	Effective portion

As of December 31, 2017 , $ 3 million of the net gains on cash flow hedges is expected to be reclassified into earnings in the next 12 months. The ineffective portion of the change in fair value of a cash flow hedge is excluded from effectiveness testing and is recognized immediately in selling, general and administrative expenses in the Consolidated Income Statements and was not material for 2017 , 2016 , and 2015 .

As of December 31, 2017 , no gains or losses on the net investment hedges are expected to be reclassified into earnings over the next 12 months. The net investment hedges did not experience any ineffectiveness for 2017 .

The fair values of our derivative assets and liabilities are measured on a recurring basis using Level 2 inputs and are determined through the use of models that consider various assumptions including yield curves, time value and other measurements.

The fair values of our derivative contracts currently included in our hedging program were as follows:

(a)

The fair value of our Senior Notes (as defined below) was determined using quoted prices in active markets for identical securities, which are considered Level 1 inputs. The fair value of our Senior Notes due 2021 (as defined below) was $ 648 million and $ 651 million as of December 31, 2017 and 2016 , respectively. The fair value of our Senior Notes due 2023 (as defined below) was $ 638 million and $ 555 million as of December 31, 2017 and 2016, respectively. The fair value of our Senior Notes due 2026 (as defined below) was $ 498 million and $ 487 million as of December 31, 2017 and 2016, respectively. The fair value of our Senior Notes due 2046 (as defined below) was $ 431 million and $ 397 million as of December 31, 2017 and 2016, respectively.


(b)	The debt issuance costs and unamortized discount is recognized as a reduction in the carrying value of the Senior Notes in the Consolidated Balance Sheets and is being amortized to interest expense in our Consolidated Income Statements over the expected remaining terms of the Senior Notes.

Senior Notes

On September 20, 2011, we issued 4.875 % Senior Notes of $ 600 million aggregate principal amount due October 2021 (the "Senior Notes due 2021"). On March 11, 2016, we issued 2.250 % Senior Notes of € 500 million aggregate principal amount due March 2023 (the "Senior Notes due 2023"). On October 11, 2016, we issued 3.250% Senior Notes of $500 million aggregate principal amount due October 2026 (the “Senior Notes due 2026”) and 4.375% Senior Notes of $400 million aggregate principal amount due October 2046 (the “Senior Notes due 2046” and, together with the Senior Notes due 2021, the Senior Notes due 2023 and the Senior Notes due 2026, the “Senior Notes”).

The Senior Notes include covenants that restrict our ability, subject to exceptions, to incur debt secured by liens and engage in sale and leaseback transactions, as well as provide for customary events of default (subject, in certain cases, to receipt of notice of default and/or customary grace and cure periods). We may redeem the Senior Notes, as applicable, in whole or in part, at any time at a redemption price equal to the principal amount of the Senior Notes to be redeemed, plus a make-whole premium. We may also redeem the Senior Notes in certain other circumstances, as set forth in the applicable Senior Notes indenture.

If a change of control triggering event (as defined in the applicable Senior Notes indenture) occurs, we will be

required to make an offer to purchase the Senior Notes at a price equal to 101 % of their principal amount plus accrued and unpaid interest to the date of repurchase.

Interest on the Senior Notes due 2021 is payable on April 1 and October 1 of each year. Interest on the Senior Notes due 2023 is payable on March 11 of each year. Interest on the Senior Notes due 2026 and the Senior Notes due 2046 is payable on May 1 and November 1 of each year beginning on May 1, 2017. As of December 31, 2017, we were in compliance with all covenants for the Senior Notes.

We used the net proceeds of the Senior Notes due 2026 and the Senior Notes due 2046, together with cash on hand, proceeds from issuances under our existing commercial paper program and borrowings under the Term Facility (as described below), to fund the acquisition of Sensus (refer to Note 3 for further information on the Sensus acquisition).

Credit Facilities

Five-Year Revolving Credit Facility

Effective March 27, 2015, Xylem entered into a Five-Year Revolving Credit Facility (the "Credit Facility") with Citibank, N.A., as administrative agent, and a syndicate of lenders. The Credit Facility provides for an aggregate principal amount of up to $ 600 million of: (i) revolving extensions of credit (the "revolving loans") outstanding at any time and (ii) the issuance of letters of credit in a face amount not in excess of $ 100 million outstanding at any time. The Credit Facility provides for increases of up to $200 million for a possible maximum total of $800 million in aggregate principal amount at our request and with the consent of the institutions providing such increased commitments.

At our election, the interest rate per annum applicable to the revolving loans will be based on either (i) a Eurodollar rate determined by reference to LIBOR, adjusted for statutory reserve requirements, plus an applicable margin or (ii) a fluctuating rate of interest determined by reference to the greatest of: (a) the prime rate of Citibank, N.A., (b) the U.S. Federal funds effective rate plus half of 1 % or (c) the Eurodollar rate determined by reference to LIBOR, adjusted for statutory reserve requirements, in each case, plus an applicable margin.

In accordance with the terms of an amendment to the Credit Facility dated August 30, 2016, we may not exceed a maximum leverage ratio of 4.00 to 1.00 (based on a ratio of total debt to earnings before interest, taxes, depreciation and amortization) for a period of 12-months following the Sensus acquisition and a maximum leverage ratio of 3.50 to 1.00 through the rest of the term. The Credit Facility also contains limitations on, among other things, incurring secured debt, granting liens, entering into sale and leaseback transactions, mergers, consolidations, liquidations, dissolutions and sales of assets. In addition, the Credit Facility contains other terms and conditions such as customary representations and warranties, additional covenants and customary events of default. As of December 31, 2017 the Credit Facility was undrawn and we are in compliance with all covenants.

European Investment Bank - R&D Finance Contract

On October 28, 2016, the Company entered into a Finance Contract (the “Finance Contract”) with the European Investment Bank (the “EIB”). The Company's wholly owned subsidiaries in Luxembourg, Xylem Holdings S.á r.l. and Xylem International S.á r.l., are the borrowers under the Finance Contract and Xylem Inc. is the Guarantor. The Finance Contract provides for up to € 105 million (approximately $ 125 million ) to finance research, development and innovation projects in the field of sustainable water and wastewater solutions during the period from 2017 through 2019 in Sweden, Germany, Italy, UK, Hungary and Austria. The Company has unconditionally guaranteed the performance of the borrowers under the Finance Contract. Under the Finance Contract, the borrowers are able to draw loans on or before April 28, 2018, with a maturity of no longer than 11 years.

Both the Finance Contract and the R&D Facility Agreement (described below) are subject to the same leverage ratio as the Credit Facility. Both agreements also contain limitations on, among other things, incurring debt, granting liens, and entering into sale and leaseback transactions, as well as other terms and conditions, such as customary representations and warranties, additional covenants and customary events of default.

Both the Finance Contract and the R&D Facility Agreement provide for fixed rate loans and floating rate loans. Under the Finance Contract, the interest rate per annum applicable to fixed rate loans is at a fixed percentage rate per annum specified by the EIB which includes the applicable margin. The interest rate per annum applicable to floating rate loans is at the rate determined by reference to EURIBOR for loans drawn in Euros and LIBOR for loans drawn in Pounds Sterling or U.S. Dollars, plus an applicable spread specified by the EIB which includes the applicable margin. The applicable margin is 59 basis points (0.59%). As of December 31, 2017 and December 31, 2016, $125 million and $110 million were outstanding under the Finance Contract, respectively.

On December 3, 2015, the Company amended and restated its Risk Sharing Finance Facility Agreement (the "R&D Facility Agreement") with the EIB to amend the maturity date. The Facility provides an aggregate principal amount of up to € 120 million (approximately $ 143 million ) to finance research projects and infrastructure development in the European Union. The Company's wholly owned subsidiaries in Luxembourg, Xylem Holdings S.á r.l. and Xylem International S.á r.l., are the borrowers under the R&D Facility Agreement. The obligations of the borrowers under the R&D Facility Agreement are guaranteed by the Company under an Amended and Restated Deed of Guarantee, dated as of December 4, 2013, in favor of the EIB.

Under the R&D Facility Agreement, the borrower was able to draw loans on or before March 31, 2016 with a maturity of no longer than 12 years . As o f December 31, 2017 and December 31, 2016 $ 0 million and $ 38 million were outstanding, respectively, under the R&D Facility Agreement. On December 15, 2017, the R&D Facility Agreement was settled for $ 44 million .

Term Loan Facility

On October 24, 2016, the Company’s subsidiary, Xylem Europe GmbH (the “borrower”) entered into a 12-month € 150 million term loan facility (the “Term Facility”) the terms of which are set forth in a term loan agreement, among the borrower, the Company, as parent guarantor and ING Bank. The Company has entered into a parent guarantee in favor of ING Bank also dated October 24, 2016 to secure all present and future obligations of the borrower under the Term Loan Agreement. The Term Facility was used to partially fund the acquisition of Sensus. As of December 31, 2016, $157 million was outstanding under the Term Loan Facility. The Term Facility matured on October 26, 2017.

Commercial Paper

Our commercial paper program generally serves as a means of short-term funding and has a combined outstanding limit of $600 million inclusive of the Five-Year Revolving Credit Facility. As of December 31, 2017, none of the Company's $600 million commercial paper program was outstanding. As of December 31, 2016 , $ 65 million of the Company's $ 600 million commercial paper program was outstanding at a weighted average interest rate of 1.12%. We will periodically borrow under this program and may borrow under it in future periods.

Note 14 . Postretirement Benefit Plans

Defined contribution plans – Xylem and certain of our subsidiaries maintain various defined contribution savings plans, which allow employees to contribute a portion of their pre-tax and/or after-tax income in accordance with specified guidelines. Several of the plans require us to match a percentage of the employee contributions up to certain limits, generally between 3.0 % – 7.0 % of employee eligible pay. Xylem’s U.S. plan also provides for transition credits for eligible U.S. employees for the first five years after the Spin-off to supplement retirement benefits in the absence of a defined benefit plan. Age plus years of eligible service greater than or equal to 60 , entitles an employee to transition credits. The liability for transition credits was approximately $ 0 million and $ 1 million at December 31, 2017 and 2016 , respectively. Matching obligations, the majority of which were funded in cash in connection with the plans, along with transition credits and other company contributions are as follows:



(in millions)	Defined Contribution
2017	38
2016	35
2015	32

The Xylem Stock Fund, an investment option under the defined contribution plan in which Company employees participate is considered an Employee Stock Ownership Plan. As a result, participants in the Xylem Stock Fund may receive dividends in cash or may reinvest such dividends into the Xylem Stock Fund. Company employees held approximately 344 thousand and 391 thousand shares of Xylem Inc. common stock in the Xylem Stock Fund at December 31, 2017 and 2016 , respectively.

Defined benefit pension plans and other postretirement plans – We historically have maintained qualified and nonqualified defined benefit retirement plans covering certain current and former employees, including hourly and union plans as well as salaried plans, which generally require up to 5 years of service to be vested and for which the benefits are determined based on years of credited service and either specified rates, final pay, or final average pay. The other postretirement benefit plans are all unfunded plans in the U.S. and Canada.

During 2017 and 2016, we made several amendments to plans that had no material impact to the Company's financial statements.

In connection with the Sensus acquisition, the Company acquired one U.S. and three German defined benefit pension plans. The four plans added $ 96 million in projected benefit obligation and $ 9 million in assets on October 31, 2016.

Effective December 30, 2016, the Company merged its six U.S. pension plans into one plan to simplify administration and reduce costs. There was no impact to the participants' benefits and no impact to the Company's financial statements.

Amounts recognized in the Consolidated Balance Sheets for pension and other employee-related benefit plans (collectively, postretirement plans) reflect the funded status of the postretirement benefit plans. The following table provides a summary of the funded status of our postretirement plans, the presentation of such balances and a summary of amounts recorded within accumulated other comprehensive income.

The unrecognized amounts recorded in accumulated other comprehensive income will be subsequently recognized as expense on a straight-line basis only to the extent they exceed 10% of the higher of the market-related value or the projected benefit obligation, over the average remaining service period of active participants, or for plans with all or substantially all inactive participants, over the average remaining life expectancy. Actuarial gains and losses incurred in future periods and not recognized as expense in those periods will be recognized as increases or decreases in other comprehensive income, net of tax.

The net actuarial loss included in accumulated other comprehensive income at the end of 2017 and expected to be recognized in net periodic benefit cost during 2018 is $ 14 million ( $ 11 million , net of tax). The prior service credit included in accumulated other comprehensive income to be recognized in 2018 is $ 4 million ( $ 3 million , net of tax).

NM	Not meaningful . The pension benefits for future service for all the U.S. pension plans are based on years of service and not impacted by future compensation increases.

Management develops each assumption using relevant company experience in conjunction with market-related data for each individual country in which plans exist. Assumptions are reviewed annually and adjusted as necessary.

The expected long-term rate of return on assets reflects the expected returns for each major asset class in which the plans hold investments, the weight of each asset class in the target mix, the correlations among asset classes and their expected volatilities. The assets of the pension plans are held by a number of independent trustees, managed by several investment institutions and are accounted for separately in the Company’s pension funds.

Our expected return on plan assets is estimated by evaluating both historical returns and estimates of future returns. Specifically, we analyze the plans’ actual historical annual return on assets, net of fees, over the past 15, 20 and 25 years; estimate future returns based on independent estimates of asset class returns; and evaluate historical broad market returns over long-term timeframes based on our asset allocation range. For the U.S. Master Trust which has only existed since 2011, historical returns were estimated using a constructed portfolio that reflects the Company’s strategic asset allocation and the historical compound geometric returns of each asset class for the longest time period available. Based on this approach, the weighted average expected long-term rate of return for all of our plan assets to be used in determining net periodic benefit costs for 2018 is estimated at 7.30 % .

The table below provides the weighted average actual rate of return generated on all of our plan assets during each of the years presented as compared to the weighted average expected long-term rates of return utilize

d in calculating the net periodic benefit costs.



	2017		2016		2015
Expected long-term rate of return on plan assets	7.30	%	7.32	%	7.38	%
Actual rate of return on plan assets	5.70	%	12.20	%	3.51	%

The assumed rate of future increases in the per capita cost of health care (the health care trend rate) is 8.72 % for 2018 , decreasing ratably to 4.50 % in 2026 . An increase or decrease in the health care trend rates by one percent per year would impact the aggregate annual service and interest components by less than $ 1 million , and impact the benefit obligation by approximately $ 4 million .

Investment Policy

The investment strategy for managing worldwide postretirement benefit plan assets is to seek an optimal rate of return relative to an appropriate level of risk for each plan. Investment strategies vary by plan, depending on the specific characteristics of the plan, such as plan size and design, funded status, liability profile and legal requirements. In general, the plans are managed closely to their strategic allocations.

On April 3, 2017 the liquid assets in two UK Plans transitioned into a new fund structure. The restructuring involved transferring a portion of the assets into pooled diversified growth funds, while some investments were sold off and some were kept in place. The pooled funds make up 64% of the assets of the two UK Plans. Liability hedging and illiquid assets remain outside of this arrangement.

The following table provides the actual asset allocations of plan assets as of December 31, 2017 and 2016 , and the related asset target allocation ranges by asset category.



	2017		2016		Target Allocation Ranges
Equity securities	35.6	%	24.2	%	20-50%
Fixed income	23.4	%	32.7	%	10-40%

Fair Value of Plan Assets

In measuring plan assets at fair value, the fair value hierarchy is applied which categorizes and prioritizes the inputs used to estimate fair value into three levels. See Note 1 "Summary of Significant Accounting Policies" for further detail on fair value hierarchy.

In certain instances, fair value is estimated using quoted market prices obtained from external pricing services. In obtaining such data from the pricing service, we have evaluated the methodologies used to develop the estimate of fair value in order to assess whether such valuations are representative of fair value, including net asset value ("NAV"). Additionally, in certain circumstances, the NAV reported by an asset manager may be adjusted when sufficient evidence indicates NAV is not representative of fair value.

The following is a description of the valuation methodologies and inputs used to measure fair value for major categories of investments.

•

Equity securities — Equities (including common and preferred shares, domestic listed and foreign listed, closed end mutual funds and exchange traded funds) are generally valued at the closing price reported on the major market on which the individual securities are traded at the measurement date. Equity securities held by the Company that are publicly traded in active markets are classified within Level 1 of the fair value hierarchy. Those equities that are held in proprietary funds pooled with other investor accounts measured at fair value using the NAV per share practical expedient are not classified in the fair value hierarchy.

•

Fixed income — United States government securities are generally valued using quoted prices of securities with similar characteristics. Corporate bonds and notes are generally valued by using pricing models (e.g. discounted cash flows), quoted prices of securities with similar characteristics or broker quotes. Fixed income securities listed on active markets are classified in Level 1. Fixed income held in proprietary funds pooled with other investor accounts measured at fair value using the NAV per share practical expedient are not classified in

the fair value hierarchy. Hedging Instruments are collateralized daily with either cash or government bonds, have daily liquidity and pricing based on observable inputs from over-the-counter markets, and are classified as Level 2.

•

Hedge funds — Hedge funds are pooled funds that employ a range of investment strategies including equity and fixed income, credit driven, macro and multi oriented strategies. The valuation of limited partnership interests in hedge funds may require significant management judgment. Generally, hedge funds are valued using the NAV reported by the asset manager, and are adjusted when it is determined that NAV is not representative of fair value. In making such an assessment, a variety of factors is reviewed, including, but not limited to, the timeliness of NAV as reported by the asset manager and changes in general economic and market conditions subsequent to the last NAV reported by the asset manager. All of the hedge funds held have lockups and/or gates. Hedge funds have unfunded commitments of $ 5 million and $ 5 million at December 31, 2017 and 2016 , respectively.

•

Private equity — Private equity includes a diversified range of strategies, including buyout funds, distressed funds, venture and growth equity funds and mezzanine funds with long-term commitments, and redemptions beginning no earlier than 2018. The valuation of limited partnership interests in private equity funds may require significant management judgment. Generally, private equity is valued using the NAV reported by the asset manager, and is adjusted when it is determined that NAV is not representative of fair value. In making such an assessment, a variety of factors is reviewed, including, but not limited to, the timeliness of NAV as reported by the asset manager and changes in general economic and market conditions subsequent to the last NAV reported by the asset manager. Private equity is not liquid and has unfunded commitments of $ 4 million and $ 7 million at December 31, 2017 and 2016 , respectively.

•

Insurance contracts and other — Primarily comprised of insurance contracts and cash. Insurance contracts are valued at contract value, which approximates fair value, and is calculated using the prior year balance adjusted for investment returns and cash flows and are generally classified as Level 3. Insurance contracts are held by certain foreign pension plans. Cash and cash equivalents are held in accounts with brokers or custodians for liquidity and investment collateral and are classified as Level 1.

The following table provides the fair value of plan assets held by our pension benefit plans by asset class.

Contributions and Estimated Future Benefit Payments

Funding requirements under governmental regulations are a major consideration in making contributions to our postretirement plans. We made contributions of $ 33 million and $ 27 million to our pension and postretirement defined benefit plans during 2017 and 2016 , respectively. A discretionary $ 6 million contribution was made to the U.S. Plan in Q3 2017 to increase the funding ratio and reduce regulatory fees. We currently anticipate making contributions to our pension and postretirement defined benefit plans in the range of $ 20 million to $ 30 million during 2018 , of which approximately $ 6 million is expected to be made in the first quarter.

The following benefit payments, which reflect expected future service, as appropriate, are expected to be paid as follows:

Note 15 . Stock-Based Compensation Plans

Our stock-based compensation program is a broad-based program designed to attract and retain employees while also aligning employees’ interests with the interests of our shareholders. In addition, members of our Board of Directors participate in our stock-based compensation program in connection with their service on our board. Share-based awards issued to employees include non-qualified stock options, restricted stock unit awards and performance share unit awards. Under the 2011 Omnibus Incentive Plan, the number of shares initially available for awards was 18 million . As of December 31, 2017 , there were approximately 7 million shares of common stock available for future grants.

Total share-based compensation costs recognized for 2017 , 2016 and 2015 were $ 21 million , $ 18 million , and $ 15 million , respectively. The unamortized compensation expense at December 31, 2017 related to our stock options, restricted share units and performance share units was $ 6 million , $ 17 million and $ 13 million , respectively, and is expected to be recognized over a weighted average period of 1.8 , 1.8 and 1.8 years, respectively.

The amount of cash received from the exercise of stock options was $ 16 million for 2017 with a tax benefit of $ 10 million realized associated with stock option exercises and vesting of restricted stock units. We classify as an operating activity the cash flows attributable to excess tax benefits arising from stock option exercises and restricted stock unit vestings.

Stock Option Grants

Options are awarded with a contractual term of ten years and generally vest over a three-year period and are exercisable within the contractual term, except in certain instances of death, retirement or disability. The exercise price per share is the fair market value of the underlying common stock on the date each option is granted. At December 31, 2017 , there were options to purchase an aggregate of 2.1 million shares of common stock. The following is a summary of the changes in outstanding stock options for 2017 :



	Share units (in thousands)		Weighted Average Exercise Price / Share		Weighted Average Remaining Contractual Term (Years)	Aggregate Intrinsic Value (in millions)
Outstanding at January 1, 2017	2,126		$	33.71	6.9
Granted	501		$	48.43
Exercised	( 494	)	$	31.95
Forfeited and expired	( 57	)	$	42.60
Outstanding at December 31, 2017	2,076		$	37.44	7.0	$	64
Options exercisable at December 31, 2017	1,147		$	33.07	5.8	$	40
Vested and non-vested expected to vest as of December 31, 2017	1,997		$	36.52	6.8	$	62

The amount of non-vested options outstanding was 0.9 million , 1.0 million and 1.0 million at a weighted average grant date fair value of $ 42.84 , $ 37.10 and $ 35.65 as of December 31, 2017 , 2016 and 2015 , respectively. The total intrinsic value of options exercised (which is the amount by which the stock price exceeded the exercise price of the options on the date of exercise) during 2017 , 2016 and 2015 was $ 14 million , $ 12 million and $ 9 million , respectively.

The fair value of each option grant was estimated on the date of grant using the binomial lattice pricing model which incorporates multiple and variable assumptions over time, including assumptions such as employee exercise patterns, stock price volatility and changes in dividends. The following are weighted-average assumptions used for 2017 , 2016 , and 2015 :



	2017			2016			2015
Dividend yield	1.49		%	1.63		%	1.57		%
Volatility	25.39		%	28.87		%	27.77		%
Risk-free interest rate	2.07		%	1.41		%	1.64		%
Expected term (in years)	5.10			5.60			5.58
Weighted-average fair value per share	$	10.66		$	9.05		$	8.49

Expected volatility is calculated based on a weighted analysis of historic and implied volatility measures for a set of peer companies and Xylem. We use historical data to estimate option exercise and employee termination behavior within the valuation model. Employee groups and option characteristics are considered separately for valuation purposes. The expected term represents an estimate of the period of time options are expected to remain outstanding. The risk-free rate is based on the U.S. Treasury yield curve in effect at the time of option grant.

Restricted Stock Unit Grants

Restricted shares granted to employees in 2017 vest over a three-year period. Restricted shares granted to employees prior to 2017 generally become fully vested upon the third anniversary of the date of grant. Prior to the time a restricted share becomes fully vested, the awardees cannot transfer, pledge, hypothecate or encumber such shares. Prior to the time a restricted share is fully vested, the awardees do not have certain rights of a stockholder, such as the right to vote and receive dividends; however, dividends accrue during the vesting period and are paid upon vesting. If an employee leaves prior to vesting, whether through resignation or termination for cause, the restricted stock unit and related accrued dividends are forfeited. If an employee retires, a pro rata portion of the restricted stock unit may vest in accordance with the terms of the grant agreements. Restricted stock units granted to Board members become fully vested upon the day prior to the next annual meeting. Our restricted stock units activity was as follows for 2017 :



	Share Units (in thousands)		Weighted Average Grant Date Fair Value / Share
Outstanding at January 1, 2017	899		$	37.67
Granted	344		49.72
Vested	( 396	)	38.16
Forfeited	( 68	)	41.00
Outstanding at December 31, 2017	779		35.39

Performance Share Units

Performance share units granted under the long-term incentive plan vest based upon performance by the Company over a three -year period against targets approved by the compensation committee of the Company's Board of Directors prior to the grant date. For the performance periods, the performance share units were granted at a target of 100 % with actual payout contingent upon the achievement of a pre-set, three-year adjusted Return on Invested Capital and cumulative adjusted net income performance target for ROIC performance share units and a relative TSR performance for TSR performance share units. The calculated compensation cost for ROIC performance share units is adjusted based on an estimate of awards ultimately expected to vest and our assessment of the probable outcome of the performance condition.

ROIC Performance Share Unit Grants

The fair value of the ROIC performance share unit awards at 100 % target is determined using the closing price of our common stock on date of grant.

Our ROIC performance share unit activity was as follows for 2017 :



	Share units (in thousands)		Weighted Average Grant Date Fair Value / Share
Outstanding at January 1, 2017	250		$	37.11
Granted	117		49.15
Forfeited	( 69	)	38.62
Outstanding at December 31, 2017	298		41.48

TSR Performance Share Unit Grants

The following is a summary of our TSR performance share unit grants for 2017 .



	Share units (in thousands)		Weighted Average Grant Date Fair Value /Share
Outstanding at January 1, 2017	108		$	46.15
Granted	117		47.79
Forfeited	( 12	)	44.19
Outstanding at December 31, 2017	213		47.04

The fair value of TSR performance share units was calculated on the date of grant using a Monte Carlo simulation model utilizing several key assumptions, including expected Company and peer company share price volatility, correlation coefficients between peers, the risk-free rate of return, the expected dividend yield and other award design features. The following are weighted-average assumptions for 2017 grants.



Volatility	30.24	%
Risk-free interest rate	1.50	%

Note 16. Capital Stock

For the year ended December 31, 2017 the Company repurchased 0.5 million shares for $ 25 million of common stock. Repurchases include both share repurchase programs approved by the Board of Directors and repurchases in relation to settlement of employee withholding obligations due as a result of the vesting of restricted stock units. The detail of repurchases by each program are as follows:

On August 24, 2015, our Board of Directors authorized the repurchase of up to $ 500 million in shares with no expiration date. The program's objective is to deploy our capital in a manner that benefits our shareholders and maintains our focus on growth. For the year ended December 31, 2017 we repurchased 0.1 million shares for $ 7 million . There were no shares repurchased under this program during 2016. There are up to $ 413 million in shares that may still be purchased under this plan as of December 31, 2017 .

On August 20, 2013, our Board of Directors authorized the repurchase of up to $ 250 million in shares with no expiration date. The program's objective was to deploy our capital in a manner that benefited our shareholders and maintain our focus on growth. As of December 31, 2015, we exhausted the authorized amount to repurchase shares under this plan.

On August 18, 2012, the Board of Directors authorized the repurchase of up to 2.0 million shares of common stock with no expiration date. The program's objective is to offset dilution associated with various Xylem employee stock plans by acquiring shares in the open market from time to time. For the year ended December 31, 2017 we repurchased 0.3 million shares for $ 13 million . There were no shares repurchased under this program during 2016. As of June 2017, we have exhausted the authorized amount to repurchase shares under this plan.

Aside from the aforementioned repurchase programs, we repurchased 0.1 million and 0.1 million shares for $ 5 million and $ 4 million during 2017 and 2016 , respectively, in relation to settlement of employee tax withholding obligations due as a result of the vesting of restricted stock units. These repurchases are included in the stock incentive plan net activity in the above table.

Note 18 . Commitments and Contingencies

Legal Proceedings

From time to time claims may be asserted against Xylem alleging injury caused by any of our products resulting from asbestos exposure. We believe there are numerous legal defenses available for such claims and would defend ourselves vigorously. Pursuant to the Distribution Agreement among ITT Corporation (now ITT LLC), Exelis and Xylem, ITT Corporation (now ITT LLC) has an obligation to indemnify, defend and hold Xylem harmless for asbestos product liability matters, including settlements, judgments, and legal defense costs associated with all pending and future claims that may arise from past sales of ITT’s legacy products.

Although the ultimate outcome of any legal matter cannot be predicted with certainty, based on present information, including our assessment of the merits of the particular claims, we do not expect that any asserted or unasserted legal claims or proceedings, individually or in aggregate, will have a material adverse effect on our results of operations, or financial condition.

We have estimated and accrued $ 10 million and $ 11 million as of December 31, 2017 and 2016 , respectively for these general legal matters.

Indemnifications

As part of our 2011 spin-off from our former parent, ITT Corporation (now ITT LLC), Exelis Inc. and Xylem will indemnify, defend and hold harmless each of the other parties with respect to such parties’ assumed or retained

100

liabilities under the Distribution Agreement and breaches of the Distribution Agreement or related spin agreements. The former parent’s indemnification obligations include asserted and unasserted asbestos and silica liability claims that relate to the presence or alleged presence of asbestos or silica in products manufactured, repaired or sold prior to October 31, 2011, the Distribution Date, subject to limited exceptions with respect to certain employee claims, or in the structure or material of any building or facility, subject to exceptions with respect to employee claims relating to Xylem buildings or facilities. The indemnification associated with pending and future asbestos claims does not expire. Xylem has not recorded a liability for material matters for which we expect to be indemnified by the former parent or Exelis Inc. through the Distribution Agreement and we are not aware of any claims or other circumstances that would give rise to material payments from us under such indemnifications. On May 29, 2015, Harris Inc. acquired Exelis. As the parent of Exelis, Harris Inc. is responsible for Exelis’s indemnification obligations under the Distribution Agreement.

Guarantees

We obtain certain stand-by letters of credit, bank guarantees and surety bonds from third-party financial institutions in the ordinary course of business when required under contracts or to satisfy insurance related requirements. As of December 31, 2017, the amount of stand-by letters of credit, bank guarantees and surety bonds was $ 240 million .

Environmental

In the ordinary course of business, we are subject to federal, state, local, and foreign environmental laws and regulations. We are responsible, or are alleged to be responsible, for ongoing environmental investigation and remediation of sites in various countries. These sites are in various stages of investigation and/or remediation and in many of these proceedings our liability is considered de minimis. We have received notification from the U.S. Environmental Protection Agency, and from similar state and foreign environmental agencies, that a number of sites formerly or currently owned and/or operated by Xylem or for which we are responsible under the Distribution Agreement, and other properties or water supplies that may be or have been impacted from those operations, contain disposed or recycled materials or wastes and require environmental investigation and/or remediation. These sites include instances where we have been identified as a potentially responsible party under federal and state environmental laws and regulations.

Accruals for environmental matters are recorded on a site-by-site basis when it is probable that a liability has been incurred and the amount of the liability can be reasonably estimated, based on current law and existing technologies. Our accrued liabilities for these environmental matters represent the best estimates related to the investigation and remediation of environmental media such as water, soil, soil vapor, air and structures, as well as related legal fees. These estimates, and related accruals, are reviewed quarterly and updated for progress of investigation and remediation efforts and changes in facts and legal circumstances. Liabilities for these environmental expenditures are recorded on an undiscounted basis. We have estimated and accrued $ 4 million and $ 4 million as of December 31, 2017 and 2016 , respectively, for environmental matters.

It is difficult to estimate the final costs of investigation and remediation due to various factors, including incomplete information regarding particular sites and other potentially responsible parties, uncertainty regarding the extent of investigation or remediation and our share, if any, of liability for such conditions, the selection of alternative remedial approaches, and changes in environmental standards and regulatory requirements. We believe the total amount accrued is reasonable based on existing facts and circumstances.

Operating Leases

We lease certain offices, manufacturing buildings, machinery, computers and other equipment. We often pay maintenance, insurance and tax expense related to leased assets. Total rent expense for the three years ended December 31, 2017 was as follows:



(in millions)	Total
2017	70
2016	63
2015	59

Minimum rental payments	$	65	$	53	$	42	$	29	$	23	$	45

Warranties

We warrant numerous products, the terms of which vary widely. In general, we warrant products against defect and specific non-performance. Warranty expense was $ 28 million , $ 32 million , and $ 32 million for 2017 , 2016 and 2015 , respectively. The table below provides changes in the combined current and non-current product warranty accruals over each period.

Note 20 . Segment and Geographic Data

Our business has three reportable segments: Water Infrastructure, Applied Water and Measurement & Control Solutions. When determining the reportable segments, the Company aggregated operating segments based on their similar economic and operating characteristics. The Water Infrastructure segment focuses on the transportation and treatment of water, offering a range of products including water and wastewater pumps, treatment equipment, and controls and systems. The Applied Water segment serves many of the primary uses of water and focuses on the residential, commercial and industrial markets. The Applied Water segment's major products include pumps, valves, heat exchangers, controls and dispensing equipment. The Measurement & Control Solutions segment focuses on developing advanced technology solutions that enable intelligent use and conservation of critical water and energy resources as well as analytical instrumentation used in the testing of water. The Measurement & Control Solutions segment's major products include smart metering, networked communications, measurement and control technologies, software and services including cloud-based analytics, remote monitoring and data management, leak detection and pressure monitoring solutions and testing equipment.

The accounting policies of each segment are the same as those described in the summary of significant accounting policies (see Note 1). The following tables contain financial information for each reportable segment:

We have also audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States) (PCAOB), the consolidated financial statements as of and for the year ended December 31, 2017, and the related notes (collectively referred to as the “financial statements”), of the Company and our report dated February 23, 2018, expressed an unqualified opinion on those financial statements.

Basis of 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 Management’s Report 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 a public accounting firm 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.
