NOTES TO THE CONDENSED CONSOLIDATED FINANCIAL STATEMENTS (UNAUDITED)

NOTE A – BASIS OF PRESENTATION

The accompanying unaudited condensed consolidated financial statements of Boston Scientific Corporation have been prepared in accordance with accounting principles generally accepted in the United States (U.S. GAAP) and with the instructions to Form 10-Q and Article 10 of Regulation S-X. Accordingly, they do not include all of the information and footnotes required by U.S. GAAP for complete financial statements. In the opinion of management, all adjustments (consisting only of normal recurring adjustments) considered necessary for fair presentation have been included. Operating results for the three months ended March 31, 2018 are not necessarily indicative of the results that may be expected for the year ending December 31, 2018 . For further information, refer to the consolidated financial statements and footnotes thereto included in Item 8 of our most recent Annual Report on Form 10-K.

Amounts reported in millions within this report are computed based on the amounts in thousands. As a result, the sum of the components reported in millions may not equal the total amount reported in millions due to rounding. Certain columns and rows within tables may not add due to the use of rounded numbers. Percentages presented are calculated from the underlying numbers in dollars. Prior year balances were subject to rounding.

Revision of Reportable Segments

Effective January 1, 2018, following organizational changes to align the company's business and organization structure focused on active implantable devices, we revised our reportable segments, in accordance with FASB ASC Topic 280, Segment Reporting. The revision reflects a reclassification of our Neuromodulation business from our Medical Surgical (MedSurg) segment to our newly created Rhythm and Neuro segment. We have revised prior year amounts to conform to the current year’s presentation (as denoted with an asterisk throughout *). There was no revision to operating segments or reporting units as a result of the organizational change. See Note C – Goodwill and Other Intangible Assets and Note K – Segment Reporting for further details.

Subsequent Events

We evaluate events occurring after the date of our most recent accompanying unaudited condensed consolidated balance sheets for potential recognition or disclosure in our financial statements. We did not identify any material subsequent events requiring adjustment to our accompanying unaudited condensed consolidated financial statements (recognized subsequent events) for the three months ended March 31, 2018 . Those items requiring disclosure (unrecognized subsequent events) in the financial statements have been disclosed accordingly. Refer to Note B – Acquisitions and Strategic Investments and Note I – Commitments and Contingencies for more information.

Accounting Standards Implemented Since December 31, 2017

ASC Update No. 2014-09

In May 2014, the FASB issued ASC Update No. 2014-09, Revenue from Contracts with Customers (Topic 606), which was subsequently updated. We adopted the standard as of January 1, 2018, using the modified retrospective method. Under this method, we applied FASB ASC Topic 606 to contracts that were not complete as of January 1, 2018 and recognized the cumulative effect of initially applying the standard as an adjustment to the opening balance of retained earnings. Results for reporting periods beginning after January 1, 2018 are presented in accordance with FASB ASC Topic 606. Prior period amounts are not adjusted and are reported in accordance with legacy GAAP requirements in FASB ASC Topic 605, Revenue Recognition .

Due to the adoption of FASB ASC Topic 606, we recorded a net reduction to opening retained earnings of $177 million on January 1, 2018, primarily related to cost of providing non-contractual post-implant support to certain customers, which we deemed immaterial in the context of the arrangement. Upon the adoption of FASB ASC Topic 606, when we sell a device with an implied non-contractual post-implant support obligation, we forward accrue the cost of the service within Selling, general and administrative expenses and recognize it at the point in time the associated revenue is earned. We release the accrual over the related service period. These costs were previously expensed as incurred due to such service obligation being non-contractual.

The impact of adopting FASB ASC Topic 606 on our unaudited condensed consolidated balance sheets as of March 31, 2018 , resulted in an increase in Other current liabilities of $59 million and an increase in Other long-term liabilities of $206 million , as a result of accruing for our post-implant support obligation. We also recorded deferred tax assets primarily related to post-implant support, resulting in an increase in Other long-term assets of $12 million and a reduction in Deferred income taxes of

Table of Contents

$41 million . The remaining impact of adopting FASB ASC Topic 606 was not material to our financial position or results of operations.

Refer to Note L – Revenue for additional details.

ASC Update No. 2016-01

In January 2016, the FASB issued ASC Update No. 2016-01, Financial Instruments - Overall (Subtopic 825-10) : Recognition and Measurement of Financial Assets and Financial Liabilities. The purpose of Update No. 2016-01 is to improve financial reporting for financial instruments by reducing the number of items recorded to other comprehensive income. We adopted Update No. 2016-01 in the first quarter of 2018, using both the modified retrospective and prospective methods. For publicly-held securities, we used the modified retrospective approach. Unrealized gains and losses previously recorded to other comprehensive income were reclassified to retained earnings and all future fair value changes will be recorded to net income. For privately-held securities, we elected the measurement alternative approach which is applied prospectively upon adoption. This approach requires entities to measure their investments at cost minus impairment, if any, plus or minus changes resulting from observable price changes in orderly transactions for the identical or a similar investment of the same issuer. The adoption of the standard did not have a material impact on our financial position or results of operations. The actual impact to future periods resulting from fair value changes of our equity investments is difficult to predict as it will depend on their future performance.

ASC Update No. 2016-16

In October 2016, the FASB issued ASC Update No. 2016-16, Income Taxes (Topic 740): Intra-Entity Transfers of Assets Other Than Inventory . The purpose of Update No. 2016-16 is to allow an entity to recognize the income tax consequences of an intra-entity transfer of an asset other than inventory when the transfer occurs, as opposed to waiting until the asset is sold to a third party, or impaired. Update No. 2016-16 was effective for annual periods beginning after December 15, 2017, including interim periods within those annual periods. We adopted Update No. 2016-16 prospectively in the first quarter of 2018 and recognized a net reduction to opening retained earnings of $55 million for income tax consequences not previously recognized for intra-entity transfers of assets other than inventories. All future income tax consequences of intra-entity transfers of assets other than inventories will be recognized through income tax expense.

ASC Update No. 2017-12

In August 2017, the FASB issued ASC Update No. 2017-12, Derivatives and Hedging (Topic 815) : Targeted Improvements to Accounting for Hedging Activities . The purpose of Update No. 2017-12 is to simplify the application of hedge accounting and better align financial reporting of hedging relationships with risk management objectives. Update No. 2017-12 was effective for annual periods beginning after December 15, 2018, including interim periods within those annual periods. We early adopted Update No. 2017-12 in the first quarter of 2018. The adoption of the standard had no impact on our financial position or results of operations.

NOTE B – ACQUISITIONS AND STRATEGIC INVESTMENTS

We did not close any material acquisitions during the first quarter of 2018 or 2017 .

On April 30, 2018, we announced the closing of our acquisition of NxThera, Inc. (NxThera), a privately-held company based in Maple Grove, Minnesota. NxThera developed the Rezûm ^® System, a minimally invasive therapy in a growing category of treatment options for patients with benign prostatic hyperplasia (BPH). The transaction consists of an upfront cash payment of $306 million , and up to an additional $100 million in potential commercial milestone payments over the next four years. We have an existing minority investment in NxThera which is expected to result in a net upfront payment of approximately $240 million upon closing, and milestone payments of up to $85 million . NxThera will be integrated into our Urology and Pelvic Health business.

On April 16, 2018, we announced the closing of our acquisition of nVision Medical Corporation (nVision), a privately-held company focused on women’s health. nVision developed the first and only device cleared by the U.S. Food and Drug Administration (FDA) to collect cells from the fallopian tubes, offering a potential platform for earlier diagnosis of ovarian cancer. The transaction consists of an upfront cash payment of $150 million , and up to an additional $125 million in potential clinical and commercial milestones over four years. nVision will be integrated into our Urology and Pelvic Health business.

Contingent Consideration

We recorded a net expense related to the changes in fair value of our contingent consideration liabilities of $5 million during the first quarter of 2018 and a net benefit related to the changes in fair value of our contingent consideration liabilities of $50 million during the first quarter of 2017 . We made $28 million of contingent payments during the first quarter of 2017 .

Changes in the fair value of our contingent consideration liabilities were as follows (in millions):



Balance as of December 31, 2017	$	169
Amounts recorded related to prior acquisitions	(22		)
Fair value adjustment	5
Balance as of March 31, 2018	$	152

As of March 31, 2018 , the maximum amount of future contingent consideration (undiscounted) that we could be required to pay was approximately $1.320 billion .

The recurring Level 3 fair value measurements of our contingent consideration liabilities include the following significant unobservable inputs:



Contingent Consideration Liabilities	Fair Value as of March 31, 2018	Valuation Technique	Unobservable Input	Range
R&D and Commercialization-based Milestones	$105 million	Discounted Cash Flow	Discount Rate	3%
			Probability of Payment	17% - 100%
			Projected Year of Payment	2018 - 2022
Revenue-based Payments	$48 million	Discounted Cash Flow	Discount Rate	11% - 15%
Revenue-based Payments	$48 million	Discounted Cash Flow	Projected Year of Payment	2018 - 2026

Projected contingent payment amounts related to some of our R&D, commercialization-based and revenue-based milestones are discounted back to the current period using a discounted cash flow (DCF) model. Projected revenues are based on our most recent internal operational budgets and long-range strategic plans. Increases in projected revenues and probabilities of payment may result in higher fair value measurements. Increases in discount rates and the time to payment may result in lower fair value measurements. Increases or decreases in any of those inputs together, or in isolation, may result in a significantly lower or higher fair value measurement.

Strategic Investments

On January 24, 2018, we closed an investment and entered into an acquisition option agreement with Millipede, Inc. (Millipede), a privately-held company that has developed the IRIS Transcatheter Annuloplasty Ring System for the treatment of severe mitral regurgitation. Under the terms of the agreements, we have purchased a portion of the outstanding shares of Millipede along with newly issued shares of the company for a total consideration of $90 million . We also have the option to acquire the remaining shares of the company at any time prior to the completion of a first in human clinical study that meets certain parameters. Upon the completion of the clinical study, Millipede has the option to compel us to acquire the remaining shares of the company. Each company’s option period expires by the end of 2019. Completion of this acquisition would result in an additional $325 million payment by us at closing with a further $125 million becoming payable upon achievement of a commercial milestone.

The aggregate carrying amount of our strategic investments were comprised of the following categories:



	As of
(in millions)	March 31, 2018		December 31, 2017
Equity method investments	$	304	$	209
Measurement alternative investments	84		81
Publicly-held securities	12		15
Notes receivable	43		47
	$	442	$	353

Table of Contents

These investments are classified as other long-term assets within our accompanying unaudited condensed consolidated balance sheets , in accordance with U.S. GAAP and our accounting policies.

As of March 31, 2018 , the book value of our equity method investments exceeded our share of the book value of the investees’ underlying net assets by approximately $335 million , which represents amortizable intangible assets and in-process research and development, corresponding deferred tax liabilities and goodwill.

NOTE C – GOODWILL AND OTHER INTANGIBLE ASSETS

The gross carrying amount of goodwill and other intangible assets and the related accumulated amortization for intangible assets subject to amortization and accumulated write-offs of goodwill are as follows:



	As of March 31, 2018					As of December 31, 2017
(in millions)	Gross Carrying Amount		Accumulated Amortization/ Write-offs			Gross Carrying Amount		Accumulated Amortization/ Write-offs

We did not have any goodwill impairments in the three months ended March 31, 2018 or 2017 . We test our goodwill balances during the second quarter of each year for impairment, or more frequently if indicators are present or changes in circumstances suggest that impairment may exist. We assess goodwill for impairment at the reporting unit level, which is defined as an operating segment or one level below an operating segment, referred to as a component. We have seven reporting units: Endoscopy, Urology and Pelvic Health, Cardiac Rhythm Management, Electrophysiology, Neuromodulation, Interventional Cardiology and Peripheral Interventions. As such, the first quarter change in our reportable segments, where Neuromodulation was reclassified from our MedSurg segment to our newly created Rhythm and Neuro segment did not trigger a goodwill impairment assessment or impact our total goodwill carrying value.

NOTE D – HEDGING ACTIVITIES AND FAIR VALUE MEASUREMENTS

Derivative Instruments and Hedging Activities

We address market risk from changes in foreign currency exchange rates and interest rates through risk management programs which include the use of derivative financial instruments. We operate these programs pursuant to documented corporate risk management policies and do not enter into derivative transactions for speculative purposes. Our derivative instruments do not subject our earnings or cash flows to material risk, as the gains or losses on these derivatives generally offset losses or gains recognized on the hedged item.

Table of Contents

We manage concentration of counterparty credit risk by limiting acceptable counterparties to major financial institutions with investment grade credit ratings, limiting the amount of credit exposure to individual counterparties and by actively monitoring counterparty credit ratings and the amount of individual credit exposure. We also employ master netting arrangements that limit the risk of counterparty non-payment on a particular settlement date to the net gain that would have otherwise been received from the counterparty. Although not completely eliminated, we do not consider the risk of counterparty default to be significant as a result of these protections. Further, none of our derivative instruments are subject to collateral or other security arrangements, nor do they contain provisions that are dependent on our credit ratings from any credit rating agency.

Our risk from changes in currency exchange rates consists primarily of monetary assets and liabilities, forecast intercompany and third-party transactions and net investments in certain subsidiaries. We manage currency exchange rate risk at a consolidated level to reduce the cost of hedging by taking advantage of offsetting transactions. We employ derivative instruments, primarily forward currency contracts, to reduce the risk to our earnings and cash flows associated with changes in currency exchange rates.

The success of our currency risk management program depends, in part, on forecast transactions denominated primarily in British pound sterling, Euro and Japanese yen. We may experience unanticipated currency exchange gains or losses to the extent the actual activity is different than forecast. In addition, changes in currency exchange rates related to any unhedged transactions may impact our earnings and cash flows.

Certain of our currency derivative instruments are designated as cash flow hedges under FASB ASC Topic 815 , Derivatives and Hedging and are intended to protect the U.S. dollar value of forecasted transactions. The gain or loss on a derivative instrument designated as a cash flow hedge is recorded in other comprehensive income (OCI) and is included in the Accumulated other comprehensive income (loss), net of tax (AOCI) caption of our unaudited condensed consolidated balance sheets until the underlying third-party transaction occurs. When the related third-party transaction occurs we recognize the gain or loss to earnings within the Cost of products sold caption of our unaudited condensed consolidated statements of operations . In the event the hedging relationship is no longer effective, or if the hedged forecast transaction becomes no longer probable of occurring, we reclassify the amount of gains or losses on the derivative instrument designated as a cash flow hedge to earnings at that time.

We also use forward currency contracts that are not part of designated hedging relationships under FASB ASC Topic 815 as a part of our strategy to manage our exposure to currency exchange rate risk related to monetary assets and liabilities and related forecast transactions. These non-designated currency forward contracts have an original time to maturity consistent with the hedged currency transaction exposures, generally less than one year, and are marked-to-market with changes in fair value recorded to earnings and reflected within the Other, net caption of our unaudited condensed consolidated statements of operations .

Our interest rate risk relates primarily to U.S. dollar borrowings partially offset by U.S. dollar cash investments. We use interest rate derivative instruments to manage our earnings and cash flow exposure to changes in interest rates. Under these agreements we and the counterparty, at specified intervals, exchange the difference between fixed and floating interest amounts calculated by reference to an agreed-upon notional principal amount. We designate these derivative instruments either as fair value or cash flow hedges under FASB ASC Topic 815 .

The changes in the fair value of interest rate derivatives designated as fair value hedges and the changes in the fair value of the underlying hedged debt instrument generally offset and are recorded within the Interest expense caption of our unaudited condensed consolidated statements of operations . We record the changes in the fair value of interest rate derivatives designated as cash flow hedges within OCI and is included within the AOCI caption of our unaudited condensed consolidated balance sheets until the underlying hedged transaction occurs, at which time we recognize the gain or loss within Interest expense . In the event the hedging relationship is no longer effective, or if the hedged forecast transaction becomes no longer probable of occurring, we reclassify the amount of gains or losses on the interest rate derivative designated as a cash flow hedge to earnings at that time.

We are amortizing the realized gains or losses from interest rate derivative instruments previously designated as fair value or cash flow hedges into earnings as a component of Interest expense over the remaining term of the hedged item in accordance with FASB ASC Topic 815 , so long as the hedge relationship remains effective. Prior to the adoption of ASC Update No. 2017-12, Derivatives and Hedging (Topic 815), the ineffective portion, if any, of our interest rate derivatives designated as either fair value or cash flow hedges was recognized in earnings in the period in which the hedging relationship exhibited ineffectiveness.

Fair Value Measurements

FASB ASC Topic 815 requires all derivative instruments to be recognized at their fair values as either assets or liabilities on the balance sheet. We determine the fair value of our derivative instruments using the framework prescribed by FASB ASC Topic 820, Fair Value Measurements and Disclosures , by considering the estimated amount we would receive or pay to transfer these instruments at the reporting date when taking into account current currency exchange rates, interest rates, the creditworthiness of the counterparty for unrealized gain positions and our own creditworthiness for unrealized loss positions. In certain instances, we may utilize financial models to measure fair value of our derivative instruments. In doing so, we use inputs that include quoted prices for similar assets or liabilities in active markets, quoted prices for identical or similar assets or liabilities in markets that are not active, other observable inputs for the asset or liability and inputs derived principally from, or corroborated by, observable market data by correlation or other means.

The following are the balances of our derivative assets and liabilities:



	Location in Unaudited Condensed Consolidated Balance Sheets (1)	As of
		March 31,		December 31,
(in millions)		2018		2017
Derivative Assets:
Designated Derivative Instruments
Forward currency contracts	Other current assets	$	3	$	7
Forward currency contracts	Other long-term assets	15		57
		17		64
Non-Designated Derivative Instruments
Forward currency contracts	Other current assets	15		18

Non-Designated Derivative Instruments
Forward currency contracts	Other current liabilities	31		21
Total Derivative Liabilities		$	154	$	90


(1)	We classify derivative assets and liabilities as current when the remaining term of the derivative contract is one year or less.

Recurring Fair Value Measurements

On a recurring basis, we measure certain financial assets and financial liabilities at fair value based upon quoted market prices. Where quoted market prices or other observable inputs are not available, we apply valuation techniques to estimate fair value. FASB ASC Topic 820 establishes a three-level valuation hierarchy for disclosure of fair value measurements. The category of a financial asset or a financial liability within the valuation hierarchy is based upon the lowest level of input that is significant to the measurement of fair value. The three levels of the hierarchy are defined as follows:


•	Level 1 – Inputs to the valuation methodology are quoted market prices for identical assets or liabilities.


•	Level 2 – Inputs to the valuation methodology are other observable inputs, including quoted market prices for similar assets or liabilities and market-corroborated inputs.


•	Level 3 – Inputs to the valuation methodology are unobservable inputs based on management’s best estimate of inputs market participants would use in pricing the asset or liability at the measurement date, including assumptions about risk.

Assets and liabilities measured at fair value on a recurring basis consist of the following:

Our investments in money market and government funds are classified within Level 1 of the fair value hierarchy because they are valued using quoted market prices. These investments are classified as cash and cash equivalents within our accompanying unaudited condensed consolidated balance sheets , in accordance with U.S. GAAP and our accounting policies. In addition to $42 million invested in money market and government funds as of March 31, 2018 , we had $245 million in interest bearing and non-interest bearing bank accounts. In addition to $21 million invested in money market and government funds as of December 31, 2017 , we had $167 million in interest bearing and non-interest bearing bank accounts.

Our recurring fair value measurements using significant unobservable inputs (Level 3) relate solely to our contingent consideration liability. Refer to Note B – Acquisitions and Strategic Investments for a discussion of the changes in the fair value of our contingent consideration liability.

Non-Recurring Fair Value Measurements

We hold certain assets and liabilities that are measured at fair value on a non-recurring basis in periods subsequent to initial recognition. The fair value of a measurement alternative investment is not estimated if there are no identified events or changes in circumstances that may have a significant adverse effect on the fair value of the investment. Refer to Note B – Acquisitions and Strategic Investments for a discussion of our strategic investments.

Refer to Note C – Goodwill and Other Intangible Assets for a discussion of the fair values and annual impairment tests of goodwill and our indefinite lived intangible assets.

The fair value of our outstanding debt obligations was $6.040 billion as of March 31, 2018 and $5.945 billion as of December 31, 2017 . We determined fair value by using quoted market prices for our publicly registered senior notes, classified as Level 1 within the fair value hierarchy, amortized cost for commercial paper and face value for term loans and credit facility borrowings outstanding. Refer to Note E – Borrowings and Credit Arrangements for a discussion of our debt obligations.

Note:	The table above does not include unamortized amounts related to interest rate contracts designated as cash flow hedges.

Revolving Credit Facility

As of March 31, 2018 and December 31, 2017 , we maintained a $2.250 billion revolving credit facility (the 2017 Facility) with a global syndicate of commercial banks that matures on August 4, 2022. This facility provides backing for the commercial paper program described below. There were no amounts borrowed under our revolving credit facility as of March 31, 2018 and December 31, 2017 .

The 2017 Facility requires that we maintain certain financial covenants, as follows:



	Covenant Requirement	Actual
	as of March 31, 2018	as of March 31, 2018
Maximum leverage ratio (1)	3.5 times	2.2 times


(1)	Ratio of total debt to consolidated EBITDA, as defined by the credit agreement, for the preceding four consecutive fiscal quarters.

The 2017 Facility provides for an exclusion from the calculation of consolidated EBITDA, as defined by the agreement, through maturity, of any non-cash charges and up to $500 million in restructuring charges and restructuring-related expenses related to our current or future restructuring plans. As of March 31, 2018 , we had $415 million of the restructuring charge exclusion remaining. In addition, any cash litigation payments (net of any cash litigation receipts), as defined by the 2017 Facility, are excluded from the calculation of consolidated EBITDA, as defined in the 2017 Facility, provided that the sum of any excluded net cash litigation payments does not exceed $2.624 billion in the aggregate. As of March 31, 2018 , we had $1.690 billion of the legal exclusion remaining.

Any inability to maintain compliance with these covenants could require us to seek to renegotiate the terms of our credit facility or seek waivers from compliance with these covenants, both of which could result in additional borrowing costs. Further, there can be no assurance that our lenders would agree to such new terms or grant such waivers on terms acceptable to us. In this case, all credit facility commitments would terminate and any amounts borrowed under the facility would become immediately due and payable. Furthermore, any termination of our credit facility may negatively impact the credit ratings assigned to our commercial paper program which may impact our ability to refinance any then outstanding commercial paper as it becomes due and payable.

Table of Contents

Commercial Paper

As of March 31, 2018 , we had $886 million of commercial paper outstanding and $1.197 billion outstanding as of December 31, 2017 . Our commercial paper program is backed by the 2017 Facility, which allows us to have a maximum of $2.250 billion in commercial paper outstanding. Outstanding commercial paper directly reduces borrowing capacity available under the 2017 Facility . As of March 31, 2018 , the commercial paper issued and outstanding had a weighted average maturity of 22 days and a weighted average yield of 2.46 percent . As of December 31, 2017 , the commercial paper issued and outstanding had a weighted average maturity of 38 days and a weighted average yield of 1.85 percent .

Senior Notes

We had senior notes outstanding of $4.800 billion as of March 31, 2018 and $4.400 billion as of December 31, 2017 .

In February 2018, we completed an offering of $1.000 billion in aggregate principal amount of 4.000% senior notes, due March 2028. We used a portion of the net proceeds from the offering to repay the $600 million plus accrued interest of our 2.650% senior notes due in October 2018. The remaining proceeds were used to repay a portion of our outstanding commercial paper.

Our senior notes were issued in public offerings, are redeemable prior to maturity and are not subject to sinking fund requirements. Our senior notes are unsecured, unsubordinated obligations and rank on parity with each other. These notes are effectively junior to borrowings under our credit and security facility, and to the extent borrowed by our subsidiaries, to liabilities of our subsidiaries (see Other Arrangements below).

Other Arrangements

As of March 31, 2018 and December 31, 2017 , we maintained a $400 million credit and security facility secured by our U.S. trade receivables maturing in February 2019. We had outstanding borrowings of $70 million as of March 31, 2018 and no outstanding borrowings as of December 31, 2017 under our credit and security facility.

We have accounts receivable factoring programs in certain European countries that we account for as sales under FASB ASC Topic 860, Transfers and Servicing . These agreements provide for the sale of accounts receivable to third parties, of up to approximately $463 million as of March 31, 2018 . We have no retained interests in the transferred receivables, other than collection and administrative responsibilities and, once sold, the accounts receivable are no longer available to satisfy creditors in the event of bankruptcy. We de-recognized $178 million of receivables as of March 31, 2018 at an average interest rate of 2.1 percent and $171 million as of December 31, 2017 at an average interest rate of 1.8 percent .

In March 2018, we entered into a factoring agreement with a commercial Japanese bank. The agreement provides for the sale of accounts receivable and promissory notes of up to 30.000 billion Japanese yen (approximately $282 million as of March 31, 2018 ). We have no retained interests in the transferred receivables, other than collection and administrative responsibilities and, once sold, the accounts receivable are no longer available to satisfy creditors in the event of bankruptcy. We de-recognized $95 million of receivables as of March 31, 2018 at an average interest rate of 0.5 percent .

In addition, we have uncommitted credit facilities with a commercial Japanese bank that provide for accounts receivable factoring and promissory notes discounting of up to 22.000 billion Japanese yen (approximately $207 million as of March 31, 2018 ). We have no retained interests in the transferred receivables, other than collection and administrative responsibilities and, once sold, the accounts receivable are no longer available to satisfy creditors in the event of bankruptcy. We de-recognized $124 million of notes receivable as of March 31, 2018 at an average interest rate of 1.5 percent and $157 million of notes receivable as of December 31, 2017 at an average interest rate of 1.3 percent . De-recognized accounts and notes receivable are excluded from trade accounts receivable, net in the accompanying unaudited condensed consolidated balance sheets .

As of and through March 31, 2018 , we were in compliance with all the required covenants related to our debt obligations. For additional information regarding the terms of our debt agreements, refer to Note E - Borrowings and Credit Arrangements of the consolidated financial statements in our most recent Annual Report on Form 10-K.

NOTE F – RESTRUCTURING-RELATED ACTIVITIES

2016 Restructuring Plan

On June 6, 2016, our Board of Directors approved and we committed to a restructuring initiative (the 2016 Restructuring Plan). The 2016 Restructuring Plan is intended to develop global commercialization, technology and manufacturing capabilities in key

Table of Contents

growth markets and build on our Plant Network Optimization (PNO) strategy, which is intended to simplify our manufacturing plant structure by transferring certain production lines among facilities and expanding operational efficiencies in support of our operating income margin goals. Key activities under the 2016 Restructuring Plan include strengthening global infrastructure through evolving global real estate assets and workplaces, developing global commercial and technical competencies, enhancing manufacturing and distribution expertise in certain regions and continuing implementation of our PNO strategy. These activities were initiated in the second quarter of 2016 and are expected to be substantially complete by the end of 2018. We revised the original estimate for the costs and savings associated with the program in the first quarter of 2018 , as approved by the Board of Directors.

The following table provides a summary of our estimates of costs associated with the 2016 Restructuring Plan by major type of cost:



Type of cost	Total Estimated Amount Expected to be Incurred
Restructuring charges:
Termination benefits	$100 million to $110 million
Other (1)	$25 million to $50 million
Restructuring-related expenses:
Other (2)	$150 million to $165 million
	$275 million to $325 million

(1) Consists primarily of consulting fees and costs associated with contract cancellations.

(2) Comprised of other costs directly related to the 2016 Restructuring Plan, including program management, accelerated depreciation and costs to transfer product lines among facilities.

Approximately $250 million to $300 million of these charges are estimated to result in cash outlays.

NOTE H – INCOME TAXES

Our effective tax rate from continuing operations is presented below:

The change in our reported tax rates for the first quarter of 2018 , as compared to the same period in 2017 , relates primarily to the impact of certain receipts and charges that are taxed at different rates than our effective tax rate, including intangible asset impairment charges, acquisition-related items, restructuring items, litigation-related items, as well as certain discrete tax items including impacts of the Tax Cuts and Jobs Act (TCJA), enacted on December 22, 2017.

As of March 31, 2018 , we had $1.240 billion of gross unrecognized tax benefits, of which a net $1.157 billion , if recognized, would affect our effective tax rate. As of December 31, 2017 , we had $1.238 billion of gross unrecognized tax benefits, of which a net $1.150 billion , if recognized, would affect our effective tax rate.

We have received Notices of Deficiency from the Internal Revenue Service (IRS) reflecting proposed audit adjustments for Guidant Corporation for its 2001 through 2006 tax years and for Boston Scientific Corporation for its 2006 and 2007 tax years. The total

Table of Contents

incremental tax liability asserted by the IRS for the applicable periods is $1.162 billion plus interest. The primary issue in dispute for all years is the transfer pricing associated with the technology license agreements between domestic and foreign subsidiaries of Guidant. In addition, the IRS has proposed adjustments in connection with the financial terms of our Transaction Agreement with Abbott Laboratories pertaining to the sale of Guidant's vascular intervention business to Abbott Laboratories in April 2006. During 2014, we received a Revenue Agent Report from the IRS reflecting significant proposed audit adjustments to our 2008, 2009 and 2010 tax years based upon the same transfer pricing methodologies that the IRS applied to our 2001 through 2007 tax years.

We do not agree with the transfer pricing methodologies applied by the IRS or its resulting assessment. We have filed petitions with the U.S. Tax Court contesting the Notices of Deficiency for the 2001 through 2007 tax years in challenge and submitted a letter to the IRS Office of Appeals protesting the Revenue Agent Report for the 2008 through 2010 tax years and requesting an administrative appeal hearing. The issues in dispute were scheduled to be heard in U.S. Tax Court in July 2016. On July 19, 2016, we entered into a Stipulation of Settled Issues with the IRS intended to resolve all of the aforementioned transfer pricing issues, as well as the issues related to our transaction with Abbott Laboratories, for the 2001 through 2007 tax years. The Stipulation of Settled Issues was contingent upon the IRS Office of Appeals applying the same basis of settlement to all transfer pricing issues for the Company’s 2008, 2009 and 2010 tax years as well as review by the United States Congress Joint Committee on Taxation (JCT). In October 2016, we reached an agreement in principle with the IRS Office of Appeals as to the resolution of transfer pricing issues in 2008, 2009 and 2010 tax years, subject to additional calculations of tax as well as documentation to memorialize our agreement. The IRS has recalculated our final tax liabilities under this agreement for all of our tax years from 2001 through 2010 and the JCT has completed its review of the recalculations for the 2001 through 2010 tax years.

In the event that the conditions in the Stipulation of Settled Items are satisfied, we expect to make net tax payments of approximately $275 million , plus interest through the date of payment with respect to the settled issues. If finalized, payments related to the resolution are expected in the next six months. We believe that our income tax reserves associated with these matters are adequate as of March 31, 2018 and we do not expect to recognize any additional charges related to resolution of this controversy. However, the final resolution of these issues remains contingent and if the Stipulation of Settled Issues is not finalized, it could have a material impact on our financial condition, results of operations, or cash flows.

We recognize interest and penalties related to income taxes as a component of income tax expense. We had $675 million accrued for gross interest and penalties as of March 31, 2018 and $655 million as of December 31, 2017 . We recognized net tax expense related to interest and penalties of $17 million during the first quarter of 2018 and $13 million in the first quarter of 2017 .

It is reasonably possible that within the next 12 months we will resolve multiple issues including transfer pricing and transactional-related issues with foreign, federal and state taxing authorities, in which case we could record a reduction in our balance of unrecognized tax benefits of up to approximately $897 million .

There are a number of key provisions under the TCJA that impact us and we continue to monitor and analyze the ramification of the new law as the implementation is executed. The final impact of the TCJA may differ from the estimates reported due to, among other things, changes in interpretations and assumptions made by us, additional guidance that may be issued by the U.S. Department of the Treasury and actions that we may take as a result. The TCJA reduces the US Federal corporate income tax rate from 35 percent to 21 percent , requires companies to pay a one-time transition tax on earnings of certain foreign subsidiaries that were previously tax deferred, and creates new taxes on certain foreign sourced earnings. Due to insufficient guidance, as well as the availability of information to accurately analyze the impact of the TCJA, we have made a reasonable estimate of the effects, as described below and in other cases we have not been able to make a reasonable estimate and continue to account for those items based on our existing accounting under FASB ASC Topic 740, Income Taxes and the provisions of the tax laws that were in effect immediately prior to enactment. In the first quarter of 2018 , we recognized an additional tax benefit of $9 million , resulting in a total provisional estimate of $852 million related to the TCJA.

We are required to record deferred tax assets and liabilities based on the enacted tax rates at which they are expected to reverse in the future. Therefore, any U.S. related deferred taxes were re-measured from 35 percent down to 21 percent based on the recorded balances as of December 31, 2017. The analysis included a preliminary assessment on the deductibility of certain amounts for which deferred tax assets may have been recorded. However, we are still analyzing certain aspects of the TCJA and refining our calculations based on the available information, which could potentially affect the measurement of these balances or give rise to new deferred tax amounts. As of March 31, 2018, we have not adjusted our provisional estimate related to re-measurement of our deferred tax balances. As of December 31, 2017 , we recorded an estimated tax benefit of approximately $99 million .

We are required to calculate a one-time transition tax based on our total post-1986 foreign earnings and profits (E&P) that we previously deferred from U.S. income taxes. In the first quarter of 2018 , we recognized an additional tax benefit of $9 million , which results in a revised provisional amount of approximately $1.035 billion . We anticipate offsetting this liability against existing

Table of Contents

tax attributes reducing the required payment to approximately $454 million which will be remitted over an eight year period. We have not yet completed our calculation of the total post-1986 E&P for these foreign subsidiaries and we continue to refine the analysis. Additionally, no income taxes have been provided for any remaining undistributed foreign earnings that are not subject to the transition tax or any additional outside basis difference inherent in these entities, as we expect these amounts will remain indefinitely reinvested in foreign operations. Determining the amount of unrecognized deferred tax liability related to any remaining undistributed foreign earnings not subject to the transition tax and additional outside basis difference in these entities is not practicable.

We are subject to a territorial tax system under the TCJA, in which we are required to provide for tax on Global Intangible Low Taxed Income (GILTI) earned by certain foreign subsidiaries. Additionally, we are required to make an accounting policy election to either recognize deferred taxes for temporary basis differences expected to reverse as GILTI in future years or provide for the tax expense related to GILTI in the year the tax is incurred as a period expense. As of March 31, 2018, we are still evaluating the effects of the GILTI provisions as guidance and interpretations continue to emerge. Therefore, we have not determined our accounting policy on the GILTI provisions. However, the standard requires that we reflect the impact of the GILTI provisions as a period expense until the accounting policy is finalized. Therefore, we have included the provisional estimate of GILTI related to current-year operations in our estimated annual effective tax rate only and will be updating the impact and accounting policy as the analysis related to the GILTI provisions is completed.

NOTE I – COMMITMENTS AND CONTINGENCIES

The medical device market in which we primarily participate is largely technology driven. As a result, intellectual property rights, particularly patents and trade secrets, play a significant role in product development and differentiation. Over the years, there has been litigation initiated against us by others, including our competitors, claiming that our current or former product offerings infringe patents owned or licensed by them. Intellectual property litigation is inherently complex and unpredictable. In addition, competing parties frequently file multiple suits to leverage patent portfolios across product lines, technologies and geographies and to balance risk and exposure between the parties. In some cases, several competitors are parties in the same proceeding or in a series of related proceedings or litigate multiple features of a single class of devices. These forces frequently drive settlement not only for individual cases, but also for a series of pending and potentially related and unrelated cases. Although monetary and injunctive relief is typically sought, remedies and restitution are generally not determined until the conclusion of the trial court proceedings and can be modified on appeal. Accordingly, the outcomes of individual cases are difficult to time, predict or quantify and are often dependent upon the outcomes of other cases in other geographies.

During recent years, we successfully negotiated closure of several long-standing legal matters and have received favorable rulings in several other matters, however, there continues to be outstanding intellectual property litigation. Adverse outcomes in one or more of these matters could have a material adverse effect on our ability to sell certain products and on our operating margins, financial position, results of operations and/or liquidity.

In the normal course of business, product liability, securities and commercial claims are asserted against us. Similar claims may be asserted against us in the future related to events not known to management at the present time. We maintain an insurance policy providing limited coverage against securities claims and we are substantially self-insured with respect to product liability claims and fully self-insured with respect to intellectual property infringement claims. The absence of significant third-party insurance coverage increases our potential exposure to unanticipated claims or adverse decisions. Product liability claims, securities and commercial litigation and other legal proceedings in the future, regardless of their outcome, could have a material adverse effect on our financial position, results of operations and/or liquidity.

In addition, like other companies in the medical device industry, we are subject to extensive regulation by national, state and local government agencies in the U.S. and other countries in which we operate. From time to time we are the subject of qui tam actions and governmental investigations often involving regulatory, marketing and other business practices. These qui tam actions and governmental investigations could result in the commencement of civil and criminal proceedings, substantial fines, penalties and administrative remedies and have a material adverse effect on our financial position, results of operations and/or liquidity.

In accordance with FASB ASC Topic 450, Contingencies , we accrue anticipated costs of settlement, damages, losses for product liability claims and, under certain conditions, costs of defense, based on historical experience or to the extent specific losses are probable and estimable. Otherwise, we expense these costs as incurred. If the estimate of a probable loss is a range and no amount within the range is more likely, we accrue the minimum amount of the range.

Table of Contents

Our accrual for legal matters that are probable and estimable was $1.511 billion as of March 31, 2018 and $1.612 billion as of December 31, 2017 and includes certain estimated costs of settlement, damages and defense. As of March 31, 2018 and December 31, 2017 , a portion of our legal accrual is funded and included in our restricted cash balance as disclosed in Note G – Supplemental Balance Sheet Information . We continue to assess certain litigation and claims to determine the amounts, if any, that management believes will be paid as a result of such claims and litigation and, therefore, additional losses may be accrued and paid in the future, which could materially adversely impact our operating results, cash flows and/or our ability to comply with our debt covenants.

In management's opinion, we are not currently involved in any legal proceedings other than those disclosed in our most recent Annual Report on Form 10-K and those specifically identified below, which, individually or in the aggregate, could have a material adverse effect on our financial condition, operations and/or cash flows. Unless included in our legal accrual or otherwise indicated below, a range of loss associated with any individual material legal proceeding cannot be estimated.

Patent Litigation

On November 9, 2015, Edwards Lifesciences, LLC filed an invalidity claim against one of our subsidiaries, Sadra Medical, Inc. (Sadra), in the High Court of Justice, Chancery Division Patents Court in the United Kingdom, alleging that a European patent owned by Sadra relating to a repositionable heart valve is invalid. On January 15, 2016, we filed our defense and counterclaim for a declaration that our European patent is valid and infringed by Edwards. On February 25, 2016, we amended our counterclaim to allege infringement of a second patent related to adaptive sealing technology. A trial was held from January 18 to January 27, 2017. On March 3, 2017, the court found one of our patents valid and infringed and some claims of the second patent invalid and the remaining claims not infringed. Both parties have filed an appeal. On March 28, 2018, the Court of Appeals affirmed the decision of the High Court.

On April 19, 2016, a subsidiary of Boston Scientific filed suit against Edwards Lifesciences Corporation in the U.S. District Court for the District of Delaware for patent infringement. We allege that Edwards’ SAPIEN™ 3 Valve infringes a patent related to adaptive sealing technology. On June 9, 2016, Edwards filed a counterclaim alleging that our Lotus™ Valve System infringes three patents owned by Edwards. On October 12, 2016, Edwards filed a petition for inter partes review of our patent with the U.S. Patent and Trademark Office (USPTO), Patent Trial and Appeal Board. On March 29, 2017, the USPTO granted the inter partes review request. On April 18, 2017, Edwards filed a second petition for inter partes review of our patent with the USPTO. On March 23, 2018, the USPTO found the patent invalid. The Company plans to appeal that decision.

On April 26, 2016, Edwards Lifesciences PVT, Inc. filed a patent infringement action against us and one of our subsidiaries, Boston Scientific Medizintechnik GmbH, in the District Court of Düsseldorf, Germany alleging a European patent (Spenser '550) owned by Edwards is infringed by our Lotus Transcatheter Heart Valve System. The trial began on February 7, 2017. On March 9, 2017, the court found that we infringed the Spenser '550 patent. The Company filed an appeal. The appeal hearing is scheduled for May 17, 2018. On April 13, 2018, the ‘550 patent was revoked by the European Patent Office.

On December 22, 2016, Edwards Lifesciences PVT, Inc. and Edwards Lifesciences SA (AG) filed a plenary summons against Boston Scientific Limited and Boston Scientific Group Public Company in the High Court of Ireland alleging that a European patent (Spenser) owned by Edwards is infringed by our Lotus Valve System. On April 13, 2018, the ‘550 patent was revoked by the European Patent Office.

On November 20, 2017, The Board of Regents, University of Texas System (UT) and TissueGen. Inc. (TissueGen), served a lawsuit against us in the Western District of Texas. The complaint against us alleges patent infringement of two U.S. patents owned by UT, relating to “Drug Releasing Biodegradable Fiber Implant” and “Drug Releasing Biodegradable Fiber for Delivery of Therapeutics,” and affects the manufacture, use and sale of our Synergy™ Stent System. On March 12, 2018, the court dismissed the action and transferred it to the United States District Court for the District of Delaware.

Product Liability Litigation

As of April 24, 2018 , approximately 49,500 product liability cases or claims related to transvaginal surgical mesh products designed to treat stress urinary incontinence and pelvic organ prolapse have been asserted against us. The pending cases are in various federal and state courts in the United States and include eight putative class actions. There were also approximately 20 cases in Canada, inclusive of one certified and three putative class actions and fewer than 25 claims in the United Kingdom. Generally, the plaintiffs allege personal injury associated with use of our transvaginal surgical mesh products. The plaintiffs assert design and manufacturing claims, failure to warn, breach of warranty, fraud, violations of state consumer protection laws and loss of consortium claims. Over 3,100 of the cases have been specially assigned to one judge in state court in Massachusetts. On February 7, 2012, the Judicial Panel on Multi-District Litigation (MDL) established MDL-2326 in the United States District Court for the Southern District of West Virginia and transferred the federal court transvaginal surgical mesh cases to MDL-2326 for coordinated pretrial proceedings. During the fourth quarter of 2013, we received written discovery requests from certain state attorneys general offices regarding our transvaginal surgical mesh products. We have responded to those requests. As of April 24, 2018 , we have entered into master settlement agreements in principle or are in final stages of entering one with certain plaintiffs' counsel to resolve an aggregate of approximately 47,500 cases and claims. These master settlement agreements provide that the settlement and distribution of settlement funds to participating claimants are conditional upon, among other things, achieving minimum required claimant participation thresholds. Of the approximately 47,500 cases and claims, approximately 21,000 have met the conditions of the settlement and are final. All settlement agreements were entered into solely by way of compromise and without any admission or concession by us of any liability or wrongdoing.

We have established a product liability accrual for known and estimated future cases and claims asserted against us as well as with respect to the actions that have resulted in verdicts against us and the costs of defense thereof associated with our transvaginal surgical mesh products. While we believe that our accrual associated with this matter is adequate, changes to this accrual may be required in the future as additional information becomes available. While we continue to engage in discussions with plaintiffs’ counsel regarding potential resolution of pending cases and claims and intend to vigorously contest the cases and claims asserted against us, that do not settle, the final resolution of the cases and claims is uncertain and could have a material impact on our results of operations, financial condition and/or liquidity. Initial trials involving our transvaginal surgical mesh products have resulted in both favorable and unfavorable judgments for us. We do not believe that the judgment in any one trial is representative of potential outcomes of all cases or claims related to our transvaginal surgical mesh products.

We did not repurchase any shares of our common stock during the first three months of 2018 or 2017 .

NOTE K – SEGMENT REPORTING

We have three reportable segments comprised of MedSurg, Rhythm and Neuro, and Cardiovascular, which represent an aggregation of our operating segments.

Each of our reportable segments generates revenues from the sale of medical devices. We measure and evaluate our reportable segments based on segment net sales and operating income, excluding intersegment profits. In 2017, we updated our presentation

Table of Contents

of segment net sales and operating income to the impact of foreign currency fluctuations, since our chief operating decision maker (CODM) reviews operating results both including and excluding the impact of foreign currency fluctuations and the following presentation more closely aligns to our consolidated financial statements. We exclude from segment operating income certain corporate-related expenses and certain transactions or adjustments that our CODM considers to be non-operational, such as amounts related to amortization expense, intangible asset impairment charges, acquisition-related items, restructuring and restructuring-related items and litigation-related items. Although we exclude these amounts from segment operating income, they are included in reported consolidated operating income (loss) and are included in the reconciliation below.

A reconciliation of the totals reported for the reportable segments to the applicable line items in our accompanying unaudited condensed consolidated statements of operations is as follows:

(1) Emerging Markets is defined as certain countries that we believe have strong growth potential based on their economic conditions, healthcare sectors and our global capabilities. Currently, we include 20 countries in our definition of Emerging Markets.

We sell our products primarily through a direct sales force. In certain international markets, we sell our products through independent distributors. We consider revenue to be earned when all of the following criteria are met: we have a contract with a customer that creates enforceable rights and obligations; promised products or services are identified; the transaction price, or the amount we expect to receive, is determinable and we have transferred control of the promised items to the customer. Transfer of control is evidenced upon passage of title and risk of loss to the customer unless we are required to provide additional services. We treat shipping and handling costs performed after a customer obtains control of the good as a fulfillment cost and record these costs as a selling expense when incurred. We recognize revenue from consignment arrangements based on product usage, or implant, which indicates that the sale is complete. We recognize a receivable at the point in time we have an unconditional right to payment. Payment terms are typically 30 days in the U.S., but may be longer in international markets.

Deferred Revenue

We record a contract liability, or deferred revenue, when we have an obligation to provide a product or service to the customer and payment is received or due in advance of our performance. When we sell a device with a future service obligation, we defer revenue on the unfulfilled performance obligation and recognize this revenue over the related service period. Many of our Cardiac Rhythm Management (CRM) product offerings combine the sale of a device with our LATITUDE™ Patient Management System, which represents a future service obligation. Generally, we do not have observable evidence of the standalone selling price related to our future service obligations; therefore we estimate the selling price using an expected cost plus a margin approach. We allocate the transaction price using the relative standalone selling price method. The use of alternative estimates could result in a different amount of revenue deferral.

Contract liabilities are classified as other current liabilities and other long-term liabilities on the balance sheet. Our deferred revenue balance as of March 31, 2018 was $393 million and $411 million as of January 1, 2018. Our contractual liabilities are primarily composed of deferred revenue related to the LATITUDE™ Patient Management System. Revenue is recognized over the average service period which is based on device and patient longevity. During the first quarter of 2018 , we recognized $26 million of revenue that was included in the above January 1, 2018 contract liability balance. We have elected not to disclose the transaction price allocated to unsatisfied performance obligations when the original expected contract duration is one year or less. In addition, we have not identified material unfulfilled performance obligations for which revenue is not currently deferred.

Variable Consideration

We generally allow our customers to return defective, damaged and, in certain cases, expired products for credit. We base our estimate for sales returns upon historical trends and record the amount as a reduction to revenue when we sell the initial product. In addition, we may allow customers to return previously purchased products for next generation product offerings. For these transactions, we defer recognition of revenue on the sale of the earlier generation product based upon an estimate of the amount of product to be returned when the next-generation products are shipped to the customer. Uncertain timing of next-generation product approvals, variability in product launch strategies, product recalls and variation in product utilization all affect our estimates related to sales returns and could cause actual returns to differ from these estimates.

We also offer sales rebates and discounts to certain customers. We treat sales rebates and discounts as a reduction of revenue and classify the corresponding liability as current. We estimate rebates for products where there is sufficient historical information available to predict the volume of expected future rebates. If we are unable to estimate the expected rebates reasonably, we record a liability for the maximum rebate percentage offered. We have entered certain agreements with group purchasing organizations

Table of Contents

to sell our products to participating hospitals at negotiated prices. We recognize revenue from these agreements following the same revenue recognition criteria discussed above.

Capitalized Contract Costs

We capitalize commission fees related to contracts with customers when the associated revenue is expected to be earned over a period that exceeds one year. Deferred commissions are primarily related to the sale of devices enabled with our LATITUDE Patient Management System. We have elected to expense commission costs when incurred for contracts with an expected duration of one year or less. Capitalized commission fees are amortized over the period the associated products or services are transferred. Similarly, we capitalize certain recoverable costs related to the delivery of the LATITUDE Remote Monitoring Service. These fulfillment costs are amortized over the average service period. Our total capitalized contract costs are immaterial to our consolidated financial statements.

NOTE N – NEW ACCOUNTING PRONOUNCEMENTS

Periodically, new accounting pronouncements are issued by the FASB or other standard setting bodies. Recently issued standards typically do not require adoption until a future effective date. Prior to their effective date, we evaluate the pronouncements to determine the potential effects of adoption on our unaudited condensed consolidated financial statements.

Standards to be Implemented

ASC Update No. 2016-02

In February 2016, the FASB issued ASC Update No. 2016-02, Leases (Topic 842) . The purpose of Update No. 2016-02 is to increase the transparency and comparability among organizations by recognizing lease assets and lease liabilities on the balance sheet, including those previously classified as operating leases under current U.S. GAAP and disclosing key information about leasing arrangements. Update No. 2016-02 is effective for annual periods beginning after December 15, 2018, including interim periods within those annual periods. Early adoption is permitted and a modified retrospective approach is required for adoption. While we are still in the process of determining the effect that the new standard will have on our financial position and results of operations, we expect to recognize additional assets and corresponding liabilities on our consolidated balance sheets, as a result of our operating lease portfolio as it exists at the date we adopt the new standard. Please refer to Note F - Lease and Other Purchase Obligations in our most recent Annual Report on Form 10-K for information regarding our most current lease activity. Additionally, we are in the process of implementing a new lease administration and lease accounting system, and updating our controls and procedures for maintaining and accounting for our lease portfolio under the new standard. As a result, we anticipate adopting the new standard on January 1, 2019.

ASC Update No. 2016-13

In June 2016, the FASB issued ASC Update No. 2016-13, Financial Instruments - Credit Losses (Topic 326) : Measurement of Credit Losses on Financial Instruments . The purpose of Update No. 2016-13 is to replace the current incurred loss impairment methodology for financial assets measured at amortized cost with a methodology that reflects expected credit losses and requires consideration of a broader range of reasonable and supportable information, including forecasted information, to develop credit loss estimates. Update No. 2016-13 is effective for annual periods beginning after December 15, 2019, including interim periods within those annual periods. Early adoption is permitted for annual periods beginning after December 15, 2018. We are in the process of determining the effect that the adoption will have on our financial position and results of operations.

No other new accounting pronouncements, issued or effective, during the period had, or are expected to have, a material impact on our condensed consolidated financial statements.

MedSurg

Endoscopy

Our Endoscopy business develops and manufactures devices to diagnose and treat a broad range of gastrointestinal (GI) and pulmonary conditions with innovative, less invasive technologies.

Our net sales of Endoscopy products of $418 million represented approximately 18 percent of our consolidated net sales for the first quarter of 2018 . Our Endoscopy net sales increase d $39 million , or 10.2 percent , in the first quarter of 2018 , as compared to the same period in the prior year. Our operational net sales, which exclude a 400 basis point impact of foreign currency fluctuations, increase d 6.2 percent as compared to the same period in the prior year. This year-over-year increase was primarily driven by growth across several of our key product franchises, including our hemostasis franchise featuring our Resolution 360™ Clips, our biliary franchise with our SpyGlass™ DS Direct Visualization System and AXIOS™ Stent and Delivery System for endoscopic ultrasound-guided transluminal drainage of symptomatic pancreatic pseudocysts, as well as our infection prevention products and pathology services.

Table of Contents

of 2018 , as compared to the same period in the prior year. Our operational net sales, which exclude a 260 basis point impact of foreign currency fluctuations, increase d 9.2 percent as compared to the same period in the prior year. This year-over-year increase was primarily attributable to growth in sales of our kidney stone products, including our LithoVue™ Digital Flexible Ureteroscope, our benign prostatic hyperplasia (BPH) business, and our men's health products, as well as growth across all of our franchises internationally.

Rhythm and Neuro

Cardiac Rhythm Management

Our Cardiac Rhythm Management (CRM) business develops and manufactures a variety of implantable devices that monitor the heart and deliver electricity to treat cardiac abnormalities.

Our net sales of CRM products of $493 million represented approximately 21 percent of our consolidated net sales for the first quarter of 2018 . Our net sales of CRM products increase d $30 million , or 6.5 percent , in the first quarter of 2018 , as compared to the same period in the prior year. Our operational net sales, which exclude a 410 basis point impact of foreign currency fluctuations, increase d 2.4 percent as compared to the same period in the prior year. This year-over-year increase was driven by continued EMBLEM™ Subcutaneous Implantable Cardiac Defibrillator (S-ICD) market penetration, the ongoing launch of our RESONATE™ family of implantable cardioverter defibrillators (ICD) and implantable cardiac resynchronization therapy defibrillators (CRT-D) in the U.S. and Europe, as well as the favorable impact from U.S. magnetic resonance imaging (MRI) safe conditional labeling, which was approved by the FDA in September 2017. Our defibrillator growth was partially offset by softness in pacemaker sales.

Electrophysiology

Our Electrophysiology business develops and manufactures less-invasive medical technologies used in the diagnosis and treatment of rate and rhythm disorders of the heart, including a broad portfolio of therapeutic and diagnostic catheters and variety of capital equipment used in the electrophysiology lab.

Our net sales of Electrophysiology products of $75 million represented approximately three percent of our consolidated net sales for the first quarter of 2018 . Our Electrophysiology net sales increase d $11 million , or 17.2 percent , in the first quarter of 2018 , as compared to the same period in the prior year. Our operational net sales, which exclude a 570 basis point impact of foreign currency fluctuations, increase d 11.5 percent as compared to the same period in the prior year. This year-over-year increase was primarily driven by increased sales of our next generation Rhythmia™ Mapping System, Rhythmia HDx™ Mapping System, related therapeutic and diagnostic catheters, and accessories.

Neuromodulation

Our Neuromodulation business develops and manufactures devices to treat various neurological movement disorders and manage chronic pain.

Our net sales of Neuromodulation products of $169 million represented approximately seven percent of our consolidated net sales for the first quarter of 2018 . Neuromodulation net sales increase d $27 million , or 19.3 percent , in the first quarter of 2018 , as compared to the same period in the prior year. Our operational net sales, which exclude a 210 basis point impact of foreign currency fluctuations, increase d 17.2 percent as compared to the same period in the prior year. This year-over-year increase was primarily driven by continued adoption of our Precision Montage™ Spinal Cord Stimulator and the launch of Spectra Wavewriter ^TM Technology SCS System and our Vercise™ Deep Brain Stimulation System in the U.S. combined with an increase in international sales.

Cardiovascular

Table of Contents

of 2018 , as compared to the same period in the prior year. Our operational net sales, which exclude a 450 basis point impact of foreign currency fluctuations, increase d 4.8 percent as compared to the same period in the prior year. This year-over-year increase was primarily related to sales of our complex percutaneous coronary interventions (PCI) product offerings driven by new launches, our structural heart product offerings including the WATCHMAN™ Left Atrial Appendage Closure (LAAC) Device and the ACURATE™ Transcatheter Aortic Valve, which was part of our Symetis acquisition in May 2017. Growth was partially offset by price challenges within the global drug-eluting coronary stent (DES) market, coupled with a strong prior period comparison for global DES.

Peripheral Interventions

Our Peripheral Interventions business develops and manufactures products used to diagnose and treat peripheral arterial diseases, including a broad line of medical devices used in percutaneous transluminal angioplasty (PTA) and peripheral vascular diseases, as well as products to diagnose, treat and ease various forms of cancer.

Our net sales of Peripheral Interventions products of $288 million represented approximately 12 percent of our consolidated net sales for the first quarter of 2018 . Our Peripheral Interventions net sales increase d $26 million , or 10.1 percent , in the first quarter of 2018 , as compared to the same period in the prior year. Our operational net sales, which exclude a 410 basis point impact of foreign currency fluctuations, increase d 6.0 percent as compared to the same period in the prior year. This year-over-year increase was primarily driven by growth in our core franchises, particularly our stent portfolio, our drug-eluting product franchise and our atherectomy systems.

Emerging Markets

As part of our strategic imperatives to drive global expansion, we are seeking to grow net sales and market share by expanding our global presence, including in Emerging Markets. We define Emerging Markets as including 20 countries that we believe have strong growth potential based on their economic conditions, healthcare sectors and our global capabilities. We have increased our investment in infrastructure in these countries in order to maximize opportunities. Our Emerging Markets net sales represented 10.7 percent of our consolidated net sales in the first quarter of 2018 and 9.6 percent in the first quarter of 2017 . In the first quarter of 2018 , our Emerging Market net sales grew 22.6 percent on a reported basis and excluding a 540 basis point impact of foreign currency fluctuations, grew 17.2 percent on an operational basis, both as compared to the same period in the prior year.

Gross Profit

Our gross profit was $1.707 billion for the first quarter of 2018 and $1.510 billion for the first quarter of 2017 . The following is a reconciliation of our gross profit margins and a description of the drivers of the change from period to period:



	Three Months
Gross profit margin - period ended March 31, 2017	69.9	%
Manufacturing cost reductions	1.7
Sales pricing and mix	0.5
Net impact of foreign currency	(1.9	)
All other, including inventory changes and other period expense	1.5
Gross profit margin - period ended March 31, 2018	71.7	%

The primary factors contributing to the increase in our gross profit margins during the first quarter, as compared to the same period in 2017 , were the positive impacts of cost reductions resulting from our process improvement programs and restructuring programs, along with the 180 basis point impact in the first quarter of 2017 primarily associated with the voluntary removal of Lotus™ Valve Devices from global, commercial and clinical sites. Partially offsetting these factors was the net negative impact of foreign currency fluctuations.

In the first quarter of 2018 , our SG&A expenses increase d $66 million , or eight percent , as compared to the first quarter of 2017 and were 70 basis points lower as a percentage of net sales. The decrease in SG&A as a percentage of sales was primarily driven by the benefit of our targeted initiatives focused on reducing SG&A, including end-to-end business process streamlining and automation, expansion of global shared services, and leveraging global sourcing.

Research and Development (R&D) Expenses

We remain committed to advancing medical technologies and investing in meaningful R&D projects across our businesses. In the first quarter of 2018 , our R&D expenses increase d $26 million , as compared to the first quarter of 2017 and were relatively flat at approximately 11 percent of net sales for both periods as a result of investments across our businesses in order to maintain a healthy pipeline of new products that we believe will contribute to profitable sales growth.

Royalty Expense

Our royalty expense was $18 million in the first quarter of 2018 , as compared to $17 million in the first quarter of 2017 , remaining relatively flat at approximately one percent of net sales for both periods.

We are contesting in U.S. Tax Court significant proposed adjustments from the Internal Revenue Service (IRS) related to its audit of our transfer pricing methodologies for the 2001 through 2007 tax years. The IRS also proposed similar transfer pricing

Table of Contents

adjustments for the 2008 through 2010 tax years. We disagree with the transfer pricing methodologies being applied by the IRS and we were scheduled to go to trial in the U.S. Tax Court in late July 2016. On July 19, 2016, we entered a Stipulation of Settled Issues with the IRS intended to resolve all of the aforementioned transfer pricing issues, as well as issues related to our transaction with Abbott Laboratories, for the 2001 through 2007 tax years. The Stipulation of Settled Issues is contingent upon the IRS Office of Appeals applying the same basis of settlement to all transfer pricing issues for the Company’s 2008, 2009 and 2010 tax years as well as review by the United States Congress Joint Committee on Taxation (JCT). In October 2016, we reached an agreement in principle with the IRS Office of Appeals as to the resolution of the transfer pricing issues in 2008, 2009 and 2010 tax years, subject to additional calculations of tax as well as documentation to memorialize our agreement. The IRS has recalculated our final tax liabilities under this agreement for all of our tax years from 2001 through 2010 and the JCT has completed its review of the recalculations for the 2001 through 2010 tax years.

Refer to Note H – Income Taxes to our unaudited condensed consolidated financial statements contained in Item 1 of this Quarterly Report on Form 10-Q for information regarding our tax litigation.

Critical Accounting Policies and Estimates

Our financial results are affected by the selection and application of accounting policies and methods. In the three months ended March 31, 2018 , there were changes to the application of critical accounting policies previously disclosed in our most recent Annual Report on Form 10-K related to the adoption of FASB ASC Topic 606, Revenue from Contracts with Customers on January 1, 2018, as described below.

Revenue Recognition

Post Implant Services

We provide non-contractual services to customers to ensure the safe and effective use of certain implanted devices. These promises are immaterial in the context of the contract. In accordance with FASB ASC Topic 606, because the revenue related to the immaterial services is recognized before they are delivered, we forward accrue the costs to provide these services at the time the devices are sold. We record these costs to selling, general and administrative expenses . We estimate the amount of time spent by our representatives performing these services and their compensation throughout the device life to determine the service cost. Changes to our business practice or the use of alternative estimates could result in a different amount of accrued cost. Refer to Note L – Revenue for further information on our adoption of FASB ASC Topic 606.

Liquidity and Capital Resources

Based on our current business plan, we believe our existing balance of cash and cash equivalents, future cash generated from operations, access to capital markets and existing credit facilities will be sufficient to fund our operations, invest in our infrastructure, pay our legal-related liabilities, pay taxes due, fund possible mergers and/or acquisitions and service and repay our existing debt for the next twelve months.

As of March 31, 2018 , we had $287 million of cash and cash equivalents on hand, comprised of $42 million invested in money market and government funds and $245 million in interest bearing and non-interest bearing bank accounts. We invest excess cash on hand in short-term financial instruments that earn market interest rates while mitigating principal risk through instrument and counterparty diversification, as well as what we believe to be prudent instrument selection. We limit our direct exposure to securities in any one industry or issuer. We also have full access to our $2.250 billion commercial paper program, which is backed by our 2017 revolving credit facility described below. As of March 31, 2018 , we had $886 million in commercial paper debt outstanding resulting in an additional $1.364 billion of available liquidity and $70 million outstanding resulting in an additional $330 million of available liquidity under our credit facility secured by our U.S. trade receivables both described below.

Please refer to our most recent annual report on Form 10-K for additional details.

Operating Activities

During the first three months of 2018 , cash provided by operating activities was $193 million , as compared to cash used for operating activities of $7 million during the first three months of 2017 , an increase of $200 million . The increase was primarily due to a reduction in litigation-related payments primarily associated with the transvaginal surgical mesh product liability cases and changes in working capital.

Investing Activities

During the first three months of 2018 , cash used for investing activities primarily relates to purchases of property, plant and equipment of $60 million and payments related to strategic investments and acquisitions of certain technologies of $103 million , primarily related to our $90 million investment in Millipede, Inc. During the first three months of 2017 , cash used for investing activities primarily included purchases of property, plant and equipment of $112 million and payments related to strategic investments and issuances of notes receivable of $28 million .

Financing Activities

Our cash flows for financing activities reflect issuances and repayments of debt, along with cash used to net share settle employee equity awards and stock issuances related to our equity incentive programs. Additionally, our financing activities included $18 million of contingent payments in the first three months of 2017 .

Commercial Paper

Senior Notes

We had senior notes outstanding of $4.800 billion as of March 31, 2018 and $4.400 billion as of December 31, 2017 .

Other Arrangements

As of and through March 31, 2018 , we were in compliance with all the required covenants related to our debt obligations.

Equity

We received $38 million during the first three months of 2018 and $33 million during the first three months of 2017 in proceeds from stock issuances related to our stock option and employee stock purchase plans. Proceeds from the exercise of employee stock options and employee stock purchases vary from period to period based upon, among other factors, fluctuations in the trading price of our common stock and in the exercise and stock purchase patterns of our employees.

Table of Contents

We did not repurchase any shares of our common stock during the first three months of 2018 and 2017 . As of March 31, 2018 , the remaining authorization to repurchase shares under our 2013 share repurchase program was $535 million .

Stock-based compensation expense related to our stock ownership plans was approximately $36 million for the first quarter of 2018 and $30 million for the first quarter of 2017 .

Contractual Obligations and Commitments

Certain of our acquisitions involve the payment of contingent consideration. See Note B – Acquisitions and Strategic Investments to our unaudited condensed consolidated financial statements contained in Item 1 of this Quarterly Report on Form 10-Q for further details regarding the estimated potential amount of future contingent consideration we could be required to pay associated with our acquisitions. There have been no other material changes to our contractual obligations and commitments as reported in our most recent Annual Report filed on Form 10-K.

Legal Matters

For a discussion of our material legal proceedings see Note I – Commitments and Contingencies to our unaudited condensed consolidated financial statements contained in Item 1 of this Quarterly Report on Form 10-Q and Note J – Commitments and Contingencies to our audited financial statements contained in Item 8 of our most recent Annual Report on Form 10-K.

Recent Accounting Pronouncements

Information regarding new accounting pronouncements implemented since December 31, 2017 is included in Note A – Basis of Presentation and information regarding new accounting pronouncements to be implemented is included in Note N – New Accounting Pronouncements to our unaudited condensed consolidated financial statements contained in Item 1 of this Quarterly Report on Form 10-Q.

Additional Information

Use of Non-GAAP Financial Measures

To supplement our unaudited condensed consolidated financial statements presented on a GAAP basis, we disclose certain non-GAAP financial measures, including adjusted net income (earnings) and adjusted net income (earnings) per share that exclude certain amounts and operational net sales growth that exclude the impact of foreign currency fluctuations. These non-GAAP financial measures are not in accordance with generally accepted accounting principles in the United States and should not be considered in isolation from or as a replacement for the most directly comparable GAAP financial measures. Further, other companies may calculate these non-GAAP financial measures differently than we do, which may limit the usefulness of those measures for comparative purposes.

To calculate adjusted net income (earnings) and adjusted net income (earnings) per share we exclude certain charges (credits) from GAAP net income, including amortization expense, intangible asset impairment charges, acquisition-related net charges (credits), restructuring and restructuring-related net charges (credits), litigation-related net charges (credits), certain investment impairment charges and certain discrete tax items, including net income tax charges resulting from the enactment of the TCJA. Amounts are tax effected at the company's effective tax rate, unless the amount is a significant unusual or infrequently occurring item in accordance with FASB ASC section 740-270-30, "General Methodology and Use of Estimated Annual Effective Tax Rate." Please refer to Part II, Item 7. Management's Discussion and Analysis of Financial Condition and Results of Operations in our most recent Annual Report filed on Form 10-K filed with the Securities and Exchange Commission for an explanation of each of these adjustments and the reasons for excluding each item.

The GAAP financial measures most directly comparable to adjusted net income and adjusted net income per share is GAAP net income and GAAP net income per share.

To calculate operational net sales, which exclude the impact of foreign currency fluctuations, we convert actual net sales from local currency to U.S. dollars using constant foreign currency exchange rates in the current and prior period. The GAAP financial measure most directly comparable to operational net sales is net sales on a GAAP basis.

Reconciliations of each of these non-GAAP financial measures to the corresponding GAAP financial measure are included elsewhere in this Quarterly Report on Form 10-Q.

Table of Contents

Management uses these supplemental non-GAAP financial measures to evaluate performance period over period, to analyze the underlying trends in our business, to assess our performance relative to our competitors, and to establish operational goals and forecasts that are used in allocating resources. In addition, management uses these non-GAAP financial measures to further its understanding of the performance of our operating segments. The adjustments excluded from our non-GAAP financial measures are consistent with those excluded from our operating segments’ measures of net sales and profit or loss. These adjustments are excluded from the segment measures reported to our chief operating decision maker that are used to make operating decisions and assess performance.

We believe that presenting adjusted net income, adjusted net income per share that exclude certain amounts and operational net sales growth that exclude the impact of changes in foreign currency exchange rates, in addition to the corresponding GAAP financial measures, provides investors greater transparency to the information used by management for its operational decision-making and allows investors to see our results “through the eyes” of management. We further believe that providing this information assists our investors in understanding our operating performance and the methodology used by management to evaluate and measure such performance.

Safe Harbor for Forward-Looking Statements

Certain statements that we may make from time to time, including statements contained in this Quarterly Report on Form 10-Q and information incorporated by reference herein, constitute “forward-looking statements” within the meaning of Section 27A of the Securities Act of 1933, as amended, and Section 21E of the Securities Exchange Act of 1934, as amended. Forward-looking statements may be identified by words like “anticipate,” “expect,” “project,” “believe,” “plan,” “may,” “estimate,” “intend” and similar words. These forward-looking statements are based on our beliefs, assumptions and estimates using information available to us at the time and are not intended to be guarantees of future events or performance. If our underlying assumptions turn out to be incorrect, or if certain risks or uncertainties materialize, actual results could vary materially from the expectations and projections expressed or implied by our forward-looking statements. As a result, readers are cautioned not to place undue reliance on any of our forward-looking statements. Except as required by law, we do not intend to update any forward-looking statements even if new information becomes available or other events occur in the future.

The forward-looking statements in this Quarterly Report on Form 10-Q are based on certain risks and uncertainties, including the risk factors described in “Part I, Item 1A. Risk Factors” in our most recent Annual Report on Form 10-K and the specific risk factors discussed below and in connection with forward-looking statements throughout this Quarterly Report on Form 10-Q, which could cause actual results to vary materially from the expectations and projections expressed or implied by our forward-looking statements. These factors, in some cases, have affected and in the future could affect our ability to implement our business strategy and may cause actual results to differ materially from those contemplated by the forward-looking statements. These additional factors include, among other things, future political, economic, competitive, reimbursement and regulatory conditions, new product introductions, demographic trends, intellectual property, litigation and governmental investigations, financial market conditions and future business decisions made by us and our competitors, all of which are difficult or impossible to predict accurately and many of which are beyond our control. We caution each reader of this Quarterly Report on Form 10-Q to consider carefully these factors.

The following are some of the important risk factors that could cause our actual results to differ materially from our expectations in any forward-looking statements. For further discussion of these and other risk factors, see “Part I, Item 1A. Risk Factors” in our most recent Annual Report on Form 10-K.

ITEM 3.	QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

We develop, manufacture and sell medical devices globally and our earnings and cash flows are exposed to market risk from changes in currency exchange rates and interest rates. We address these risks through a risk management program that includes the use of derivative financial instruments. We operate the program pursuant to documented corporate risk management policies. We do not enter derivative transactions for speculative purposes. Gains and losses on derivative financial instruments substantially offset losses and gains on underlying hedged exposures. Furthermore, we manage our exposure to counterparty risk on derivative instruments by entering into contracts with a diversified group of major financial institutions and by actively monitoring outstanding positions.

Our currency risk consists primarily of foreign currency denominated firm commitments, forecasted foreign currency denominated intercompany and third-party transactions and net investments in certain subsidiaries. We use both nonderivative (primarily European manufacturing operations) and derivative instruments to manage our earnings and cash flow exposure to changes in currency exchange rates. We had currency derivative instruments outstanding in the contract amount of $6.161 billion as of March 31, 2018 and $5.923 billion as of December 31, 2017 . A ten percent appreciation in the U.S. dollar’s value relative to the hedged currencies would increase the derivative instruments’ fair value by $350 million as of March 31, 2018 as compared to $321 million as of December 31, 2017 . A ten percent depreciation in the U.S. dollar’s value relative to the hedged currencies would decrease the derivative instruments’ fair value by $428 million as of March 31, 2018 as compared to $421 million as of December 31, 2017 . Any increase or decrease in the fair value of our currency exchange rate sensitive derivative instruments would be substantially offset by a corresponding decrease or increase in the fair value of the hedged underlying asset, liability or forecasted transaction, resulting in minimal impact on our consolidated statements of operations.

Our interest rate risk relates primarily to U.S. dollar borrowings partially offset by U.S. dollar cash investments. We have historically used interest rate derivative instruments to manage our earnings and cash flow exposure to changes in interest rates. We had no interest rate derivative instruments outstanding as of March 31, 2018 and December 31, 2017 . As of March 31, 2018 , $4.800 billion of our outstanding debt obligations were at fixed interest rates, representing approximately 84 percent of our total debt.

Refer to Note D – Hedging Activities and Fair Value Measurements to our unaudited condensed consolidated financial statements contained in Item 1 of this Quarterly Report on Form 10-Q for further information regarding our derivative financial instruments.

ITEM 4.	CONTROLS AND PROCEDURES

Evaluation of Disclosure Controls and Procedures

Our management, with the participation of our Chief Executive Officer (CEO) and our Chief Financial Officer (CFO), evaluated the effectiveness of our disclosure controls and procedures as of March 31, 2018 pursuant to Rule 13a-15(b) of the Securities Exchange Act of 1934, as amended (the Exchange Act). Disclosure controls and procedures are designed to ensure that material information required to be disclosed by us in the reports that we file or submit under the Exchange Act is recorded, processed, summarized and reported within the time periods specified in the SEC’s rules and forms and that such material information is accumulated and communicated to our management, including our CEO and CFO, as appropriate, to allow timely decisions regarding required disclosure. Based on their evaluation, our CEO and CFO concluded that, as of March 31, 2018 , our disclosure controls and procedures were effective.

Changes in Internal Control Over Financial Reporting

During the three month period ended March 31, 2018 , we implemented certain controls related to the adoption of FASB ASC Topic 606, effective January 1, 2018. These controls were designed and implemented to ensure the completeness and accuracy over financial reporting. With the exception of the controls implemented for FASB ASC Topic 606, there were no changes in our internal control over financial reporting during the three month period ended March 31, 2018 that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.
