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. When used in this report, the terms, "we," "us," "our," and "the Company" mean Boston Scientific Corporation and its divisions and subsidiaries. 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 and nine months ended September 30, 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 our 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 sheet 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 and nine months ended September 30, 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 FASB ASC Topic 606, 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 retained earnings of $177 million on January 1, 2018, primarily related to the cost of providing non-contractual post-implant support to certain customers, which we historically 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 resulted in an increase in Other current liabilities of $59 million and an increase in Other long-term liabilities of $205 million as of September 30, 2018, 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 $41

7

million as of September 30, 2018. 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 (loss) were reclassified to retained earnings,and all future fair value changes will be recorded to Net income (loss). For privately-held securities, we elected the measurement alternative approach for our existing investments, 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 (benefit).

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.

On April 30, 2018, we announced the closing of our acquisition of NxThera, Inc. (NxThera), a privately-held company that developed the Rezûm™ System, a minimally invasive therapy in a growing category of treatment options for patients with benign prostatic hyperplasia (BPH). We held a minority interest immediately prior to the acquisition date. The transaction price to acquire the remaining stake consists of an upfront cash payment of approximately $240 million and up to approximately $85 million in payments contingent upon commercial milestones over the next four years. We are in the process of integrating NxThera into our Urology and Pelvic Health business.

nVision Medical Corporation

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 price consists of an upfront cash payment of $150 million and up to an additional $125 million in payments contingent upon clinical and commercial milestones over the next four years. We are in the process of integrating nVision into our Urology and Pelvic Health business.

In addition, we completed other individually immaterial acquisitions in the first nine months of2018 for total consideration of $50 million in cash at closing plus aggregate contingent consideration of up to $10 million.

We recorded gains of $142 million in the third quarter of 2018 and $182 million in the first nine months of 2018 within Other, net on our unaudited condensed consolidated statements of operations based on the difference between the book values and the fair values of our previously-held investments immediately prior to the acquisition dates, which aggregate to $250 million. We remeasured the fair value of each previously-held investment based on the implied enterprise value and allocation of purchase price consideration according to priority of equity interests.

Purchase Price Allocation

We accounted for these acquisitions as business combinations, and in accordance with FASB ASC Topic 805, Business Combinations, we recorded the assets acquired and liabilities assumed at their respective fair values as of the acquisition dates. The components of the aggregate preliminary purchase prices are as follows:

(in millions)
Payments for acquisitions, net of cash acquired	$	969
Fair value of contingent consideration	190
Fair value of prior interests	250
	$	1,409

9

The following summarizes the preliminary purchase price allocations for the acquisitions as of September 30, 2018:

(in millions)
Goodwill	$	619
Amortizable intangible assets	707
Indefinite-lived intangible assets	213
Other assets acquired	99
Liabilities assumed	(14		)
Deferred tax liabilities	(215		)
	$	1,409

We allocated a portion of the preliminary purchase prices to specific intangible asset categories as follows:

	Amount Assigned (in millions)		Amortization Period (in years)	Risk-Adjusted Discount Rates used in Purchase Price Allocation
Amortizable intangible assets:
Technology-related	$	697	10 - 14	17% - 23%
Other intangible assets	10		6 - 13	13% - 15%
Indefinite-lived intangible assets:
In-process research and development (IPR&D)	213		N/A	15%
	$	920

2017 Acquisitions

Symetis SA

On May 16, 2017, we announced the closing of our acquisition of Symetis SA (Symetis), a privately-held Swiss structural heart company focused on minimally-invasive transcatheter aortic valve replacement devices. The transaction price consists of an upfront cash payment of approximately $430 million. We are in the process of integrating Symetis into our Interventional Cardiology business.

Purchase Price Allocation

We accounted for the acquisition of Symetis as a business combination, and in accordance with FASB ASC Topic 805, we recorded the assets acquired and liabilities assumed at their respective fair values as of the acquisition date. The purchase price was comprised of the following component:

(in millions)
Payment for acquisition, net of cash acquired	$	391

The following summarizes the purchase price allocation for the Symetis acquisition as of September 30, 2018:

(in millions)
Goodwill	$	183
Amortizable intangible assets	278
Other assets acquired	25
Liabilities assumed	(95		)
	$	391

10

We allocated a portion of the purchase price to specific intangible asset categories as follows:

	Amount Assigned (in millions)		Amortization Period (in years)	Risk-Adjusted Discount Rates used in Purchase Price Allocation
Amortizable intangible assets:
Technology-related	$	268	13	24%
Other intangible assets	10		2 - 13	24%
	$	278

Our technology-related intangible assets consist of technical processes, intellectual property and institutional understanding with respect to products and processes that we will leverage in future products or processes and will carry forward from one product generation to the next. We used the multi-period excess earnings method, a form of the income approach, to derive the fair value of the technology-related intangible assets and are amortizing them on a straight-line basis over their assigned estimated useful lives.

Goodwill was primarily established due to synergies expected to be gained from leveraging our existing operations as well as revenue and cash flow projections associated with future technologies and has been allocated to our reportable segments based on the relative expected benefit. Based on preliminary estimates updated for applicable regulatory changes, the goodwill recorded relating to our 2018 and 2017 acquisitions is not deductible for tax purposes.

Our IPR&D intangible assets that are not subject to amortization (indefinite-lived intangible assets) represent technical processes, intellectual property and/or institutional understanding acquired through business combinations that are fundamental to the ongoing operations of our business and have no limit to their useful life.

Contingent Consideration

Changes in the fair value of our contingent consideration liability were as follows:

(in millions)
Balance as of December 31, 2017	$	169
Amounts recorded related to current year acquisitions	190
Purchase price adjustments related to prior year acquisitions	(22		)
Contingent consideration expense (benefit)	(12		)
Contingent consideration payments	(21		)
Balance as of September 30, 2018	$	305

As of September 30, 2018, the maximum amount of future contingent consideration (undiscounted) that we could be required to pay was approximately $780 million. The maximum amount of future contingent consideration (undiscounted) decreased approximately $540 million compared to the amount as of December 31, 2017 due primarily to the expiration of certain contingent consideration arrangements in the third quarter of 2018.

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

Contingent Consideration Liability	Fair Value as of September 30, 2018	Valuation Technique	Unobservable Input	Range
R&D, Regulatory and Commercialization-based Milestones	$201 million	Discounted Cash Flow	Discount Rate	3	%	-	4%
			Probability of Payment	17	%	-	99%
			Projected Year of Payment	2018		-	2022
Revenue-based Payments	$104 million	Discounted Cash Flow	Discount Rate	11	%	-	15%
			Projected Year of Payment	2018		-	2026

11

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

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 an additional $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)	September 30, 2018		December 31, 2017
Equity method investments	$	291	$	209
Measurement alternative investments	73		81
Publicly-held securities	1		15
Notes receivable	19		47
	$	384	$	353

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 September 30, 2018, the carrying amount of our aggregated equity method investments exceeded our share of the underlying equity in net assets by approximately $321 million, which represents amortizable intangible assets, IPR&D, 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 September 30, 2018					As of December 31, 2017

Effective January 1, 2018, we reclassified our Neuromodulation operating segment and associated goodwill balance from our MedSurg reportable segment to our Rhythm and Neuro reportable segment as discussed in Note A – Basis of Presentation. This change did not trigger a goodwill impairment assessment or impact our total goodwill carrying value. The following represents our goodwill balance by global reportable segment:

Goodwill and Indefinite-Lived Intangible Asset Impairment Testing

We test our goodwill balances in the second quarter of each year for impairment, or more frequently if impairment indicators are present or changes in circumstances suggest an impairment may exist. In the second quarter of 2018, we performed our annual goodwill impairment test for all of our reporting units and concluded the fair value of each reporting unit exceeded its carrying value.

In performing the goodwill impairment assessment, we utilized both the optional qualitative assessment and the quantitative approach prescribed under FASB ASC Topic 350, Intangibles - Goodwill and Other. In 2018, we performed a qualitative assessment for our Urology and Pelvic Health and Neuromodulation reporting units since their fair values have historically exceeded carrying value by greater than 100 percent. The remaining reporting units were quantitatively tested for impairment. For the reporting units subject to a qualitative assessment, if it is determined that it is more likely than not that the fair value of the reporting unit is less than its carrying value, the quantitative approach of the goodwill impairment test is necessary. In 2018, for all reporting units tested using the qualitative assessment, we concluded that it was unnecessary to perform the quantitative impairment test. For all reporting units tested using the quantitative approach, we concluded that the fair value of each reporting unit exceeded its carrying value.

In the third quarter of 2018, we performed our annual impairment test of all IPR&D projects and our indefinite-lived core technology assets using the optional qualitative assessment approach and determined that there were no impairment indicators. In addition, we verified that their classification as indefinite-lived assets continues to be appropriate.

Refer to Critical Accounting Policies and Estimates within Part II, Item 7. Management's Discussion and Analysis of Financial Condition and Results of Operations contained in our most recent Annual Report on Form 10-K for further discussion of our annual goodwill and indefinite-lived intangible asset impairment testing.

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 to material risk, as the gains or losses on these derivatives generally offset losses or gains recognized on the hedged item.

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.

13

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 (loss), net of tax (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 in 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, which 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.

Certain of our currency forward contracts are designated as net investment hedges under FASB ASC Topic 815 and are intended to hedge a portion of our net investments in certain of our entities with functional currencies denominated in Euro, Swiss franc, and Japanese yen functional operating entities. We have elected to use the spot method to assess effectiveness for our derivatives that are designated as net investment hedges. Under the spot method, the change in fair value attributable to changes in the spot rate is recorded in the Foreign currency translation adjustment (CTA), which is included within the AOCI caption of our unaudited condensed consolidated balance sheets. Therefore, the spot-forward difference is excluded from the assessment of effectiveness and accounted for separately.

Consistent with FASB ASC Topic 815, we have elected to amortize the excluded spot-forward difference associated with the currency forward contracts as calculated at the date of designation. Amortization will be recognized on a straight-line basis over the term of the currency forward contracts from the AOCI caption of our unaudited condensed consolidated balance sheets to reported earnings as a reduction of Interest expense.

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 and 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
(in millions)		September 30, 2018		December 31, 2017
Derivative Assets:
Designated Derivative Instruments
Forward currency contracts	Other current assets	$	48	$	7
Forward currency contracts	Other long-term assets	147		57
		195		64
Non-Designated Derivative Instruments
Forward currency contracts	Other current assets	61		18
Total Derivative Assets		$	256	$	82
Derivative Liabilities:
Designated Derivative Instruments
Forward currency contracts	Other current liabilities	$	5	$	37
Forward currency contracts	Other long-term liabilities	10		33
		14		69
Non-Designated Derivative Instruments
Forward currency contracts	Other current liabilities	29		21
Total Derivative Liabilities		$	44	$	90

(1) We classify derivative assets and liabilities as current when the settlement date 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 $30 million invested in money market and government funds as of September 30, 2018, we had $138 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 Level 3 inputs relate solely to our contingent consideration liability. Refer to Note B – Acquisitions and Strategic Investmentsfor 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.

The fair value of our outstanding debt obligations was $6.821 billion as of September 30, 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 September 30, 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 outstanding under our revolving credit facility as of September 30, 2018 andDecember 31, 2017.

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

	Covenant Requirement	Actual
	as of September 30, 2018	as of September 30, 2018
Maximum leverage ratio (1)	3.5 times	2.4 times

(1) Ratio of total debt to consolidated EBITDA, as defined by the 2017 Facility, 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 September 30, 2018, we had $386 millionof 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 September 30, 2018, we had $1.384 billionof 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.

20

Commercial Paper

As of September 30, 2018, we had $816 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 September 30, 2018, the commercial paper issued and outstanding had a weighted average maturity of 29days and a weighted average yield of2.58 percent. As of December 31, 2017, the commercial paper issued and outstanding had a weighted average maturity of 38days and a weighted average yield of1.85 percent.

Senior Notes

We had senior notes outstanding of $4.800 billion as ofSeptember 30, 2018 and$4.400 billionas ofDecember 31, 2017.

In February 2018, we completed an offering of$1.000 billion in aggregate principal amount of4.000%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 our2.650%senior notes due in October 2018. The remaining proceeds were used to repay a portionof 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).

Term Loan

On August 20, 2018, we entered into a $1.000 billion Term Loan Credit Agreement (August 2019 Term Loan), maturing on August 19, 2019, which is presented within Current debt obligations in the accompanying unaudited condensed consolidated balance sheets. Borrowings under the August 2019 Term Loan bear interest at an annual rate of LIBOR plus 0.65%. The August 2019 Term Loan requires that we comply with certain covenants, including financial covenants with respect to maximum leverage consistent with the 2017 Facility. As of September 30, 2018, we had $1.000 billion outstanding under our August 2019 Term Loan. We used the proceeds from the August 2019 Term Loan to repay a portion of our outstanding commercial paper.

Other Arrangements

As of September 30, 2018 and December 31, 2017, we maintained a $400 millioncredit and security facility secured by our U.S. trade receivables maturing in February 2019.We had no outstanding borrowings as of September 30, 2018and December 31, 2017 under our credit and security facility.

We have accounts receivable factoring programs in certain European countries and with commercial banks in Japan which include promissory notes discounting programs. We account for our factoring programs as sales under FASB ASC Topic 860, Transfers and Servicing. We have no retained interest in the transferred receivables, other than collection and administration, and once sold, the accounts receivable are no longer available to satisfy creditors in the event of bankruptcy. Amounts de-recognized for accounts and notes receivable, which are excluded from Trade accounts receivable, net in the accompanying unaudited condensed consolidated balance sheets, are aggregated by contract denominated currency below (in millions):

	As of September 30, 2018						As of December 31, 2017

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 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. The majority of the costs associated with this Plan are expected to be incurred 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	$80 million to $90 million
Other (1)	$25 million to $50 million
Restructuring-related expenses:
Other (2)	$170 million to $185 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, fixed asset write-offs and costs to transfer product lines among facilities.

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

The following presents these costs (credits) by major type and line item within our accompanying unaudited condensed consolidated statements of operations (in millions):

NOTE H – INCOME TAXES

Our effective tax rate from continuing operations is presented below:

	Three Months Ended September 30,				Nine Months Ended September 30,
	2018		2017		2018		2017
Effective tax rate from continuing operations	5.3	%	8.5	%	(14.1	)%	(2.0	)%

The change in our reported tax rates for the third quarter and the first nine months of 2018, as compared to the same periods in 2017, relates primarily to the impact of certain receipts and charges that are taxed at different rates than our effective tax rate. These receipts and charges include intangible asset impairment charges, acquisition-related items, restructuring items, litigation-related items, as well as certain discrete tax items including the effective settlement of our transfer pricing dispute with the Internal Revenue Service (IRS) for the 2001 through 2010 tax years and the impacts of the Tax Cuts and Jobs Act (TCJA), enacted on December 22, 2017.

In the second quarter of 2018, a decision was entered by the United States Tax Court resolving all disputes related to the transfer pricing issues for Guidant Corporation's 2001 through 2006 tax years and our 2006 and 2007 tax years as well as the tax issues related to our 2006 transaction with Abbott Laboratories. Additionally, we resolved all issues with the IRS Office of Appeals for our 2008 through 2010 tax years, including the transfer pricing issue and other unrelated issues. The final settlement calculation included certain elections made in these relevant years and resulted in a final net tax payment of $303 million plus $307 million of estimated interest, which was remitted in the second quarter of 2018. Due to the final settlement of these disputes, we recorded a net tax benefit of $250 million in the first nine months of2018.

We currently expect to resolve the IRS examination of our 2011 through 2013 tax years in the next six months. We expect that the exam will be concluded utilizing the same transfer pricing methodologies employed in the 2001 through 2010 tax years. We believe we have recorded sufficient reserves with respect to these periods and therefore do not expect to recognize any additional charges related to the resolution of the 2011 through 2013 tax years.

As of September 30, 2018, we had $511 million of gross unrecognized tax benefits, of which a net $438 million, 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. The change in our gross unrecognized tax benefit is primarily related to reaching settlements with tax authorities.

We recognize interest and penalties related to income taxes as a component of income tax expense. We had $81 million accrued for gross interest and penalties as of September 30, 2018 and $655 million as of December 31, 2017. The change in our accrued interest and penalties is primarily related to reaching settlements with tax authorities. We recognized net tax expense related to interest and penalties of $3 million in the third quarter of 2018, $14 million in the third quarter of 2017, $22 million in the first nine months of2018 and $40 million in the first nine months of2017.

It is reasonably possible that within the next 12 months we will resolve multiple 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 $226 million.

There are a number of key provisions under the TCJA that impact us and we continue to monitor and analyze the ramifications 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 U.S. 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. We have not recognized any additional tax in the third quarter of 2018, but we will continue to analyze the TCJA impact in the fourth quarter. In the first nine months of2018, we recognized an additional tax benefit of $37 million related to settling our transfer pricing dispute with the IRS, resulting in a total provisional estimate of $824 million related to the TCJA.

26

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 September 30, 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 subsidiaries' earnings and profits (E&P) that we previously deferred from U.S. income taxes. As a result of settling our various tax audits, the revised provisional amount of transition tax is approximately $866 million. We anticipate offsetting this liability against existing tax attributes reducing the required payment to approximately $506 million, which will be remitted over an eight-year period. We remitted the first estimated installment payment in the second quarter of 2018. We have not yet completed our calculation of the total post-1986 E&P, and we continue to refine the analysis. We expect that our undistributed foreign earnings as of December 31, 2017 will remain indefinitely reinvested in our foreign operations. Accordingly, no income taxes beyond the federal and state impact of the transition tax have been provided for these undistributed foreign earnings or any additional outside basis difference inherent in these entities. Determining the amount of unrecognized deferred tax liability related to any remaining undistributed foreign earnings 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 September 30, 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, Securities and Exchange Commission (SEC) Staff Accounting Bulletin (SAB) No. 118 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.

27

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.

Our accrual for legal matters that are probable and estimable was $1.162 billion as of September 30, 2018 and $1.612 billion as of December 31, 2017 and includes certain estimated costs of settlement, damages and defense. The decrease in our legal accrual was primarily due to settlement payments, authorized in 2018, associated with product liability cases or claims related to transvaginal surgical mesh products. A portion of our legal accrual is funded and included in our restricted cash and restricted cash equivalent balances of $812 million as of September 30, 2018 and $829 million as of December 31, 2017, as disclosed in Note G – Supplemental Balance Sheet Information. We recorded litigation-related net charges of $18 million in the third quarter and first nine months of2018. We recorded a litigation-related net credit of $12 million in the third quarter of 2017 and a litigation-related net charge of $196 million in the first nine months of2017. 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, our Quarterly Report on Form 10-Q for the periods ended March 31, 2018 and June 30, 2018 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 April 19, 2016, a subsidiary of Boston Scientific filed suit against Edwards Lifesciences Corporation (Edwards) 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 our patent invalid. The Company filed an appeal before the United States Court of Appeals for the Federal Circuit on May 24, 2018.

On November 29, 2016, Nevro Corp. (Nevro) filed a patent infringement action against us and one of our subsidiaries, Boston Scientific Neuromodulation Corporation, in the U.S. District Court for the Northern District of California alleging that six U.S. patents (Alataris) owned by Nevro are infringed by our spinal cord stimulation systems. On June 29, 2017, Nevro amended the complaint to add an additional patent (Fang). We deny the plaintiff's allegations and intend to defend ourselves vigorously. On July 24, 2018, summary judgment was entered in favor of the Company and on July 31, 2018, we received final judgment and dismissal of the action. On July 31, 2018, Nevro filed an appeal.

On August 1, 2018, the Company filed a patent infringement action on the merits in Dusseldorf, Germany against Edwards Lifesciences Corporation and Edwards Lifesciences GmbH (collectively Edwards) alleging that the Sapien 3^™ device and Sapien 3 Ultra™ device infringed a patent owned by the Company.

On August 3, 2018, the Company filed a preliminary injunction request in Dusseldorf, Germany against Edwards Lifesciences Corporation and Edwards Lifesciences GmbH (collectively Edwards) alleging that the Sapien 3 Ultra infringed a patent owned by the Company. On October 23, 2018, the court found that the Sapien 3 Ultra infringed the patent. Edwards has the right to appeal.

On April 21, 2018, the Company and Boston Scientific Neuromodulation Corporation filed a patent infringement, theft of trade secrets and tortious interference with a contract action against Nevro Corp. in U.S. District Court for the District of Delaware, and amended the complaint on July 18, 2018, alleging that nine U.S. patents owned by Boston Scientific Neuromodulation Corporation are infringed by Nevro’s Senza™ I and Senza™ II Spinal Cord Stimulation Systems.

28

On August 22, 2018, Edwards Lifesciences LLC filed a patent infringement action against Boston Scientific Corporation, in the U. S. District Court of Delaware, alleging that two U.S. patents (Schweich) owned by them are infringed by our Watchman™ Left Atrial Appendage Closure Device, Watchman Delivery System and Watchman Access System.

Product Liability Litigation

No individual lawsuits remain pending in state court jurisdictions against Guidant, alleging personal injuries associated with defibrillators or pacemakers involved in certain 2005 and 2006 product communications. Further, we are aware of approximately six Guidant product liability lawsuits pending in international jurisdictions associated with defibrillators or pacemakers, including devices involved in the 2005 and 2006 product communications. Four of these suits are pending in Canada involving certain models of Guidant pacemakers, three of which are stayed pending the outcome of one lead class action. On May 8, 2009, the Justice of Ontario Court certified a class of persons in whom pacemakers were implanted in Canada and a class of family members with derivative claims. In each case, these matters generally seek monetary damages from us. This class action has been inactive since 2011. On March 24, 2014, the Ontario Superior Court approved a $3 million settlement of a class action involving certain models of Guidant defibrillators. We believe Guidant has satisfied its obligations pursuant to the settlement agreement.

As of October 23, 2018, approximately 51,000 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 U.S. and include eight putative class actions. There were also fewer than 25 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 U.S. 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 October 23, 2018, we have entered into master settlement agreements in principle or are in the final stages of entering one with certain plaintiffs' counsel to resolve an aggregate of approximately 49,500 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 49,500 cases and claims, approximately 30,000 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.

Other Proceedings

On September 12, 2018, Channel Medsystems, Inc. (Channel) filed a complaint in Delaware Chancery Court against us for alleged breach of a $275 million purchase agreement. Channel alleges that we breached the agreement by terminating it. We have answered the complaint, deny the claims by Channel and have counterclaimed to recover part of our investment in Channel, alleging fraud in the inducement. The court has set a trial date of April 15, 2019.

Refer to Note H – Income Taxes for information regarding our tax litigation.

Matters Concluded Since December 31, 2017

On October 28, 2016, the Regents of the University of California filed a patent infringement action against us in the U.S. District Court for the Northern District of California alleging that two U.S. patents (Lesh) owned by the Regents of the University of

29

California are infringed by certain of our catheters and other devices used to treat atrial fibrillation. The Company and the Regents settled the matter, and the case was dismissed on June 20, 2018.

On May 19, 2005, G. David Jang, M.D. filed suit against us alleging breach of contract relating to certain patent rights covering stent technology. The suit was filed in the U.S. District Court for the Central District of California seeking monetary damages and rescission of contract. After a Markman ruling relating to the Jang patent rights, Dr. Jang stipulated to the dismissal of certain claims alleged in the complaint with a right to appeal and the parties subsequently agreed to settle the other claims. In May 2007, Dr. Jang filed an appeal with respect to the remaining patent claims and in July 2008, the Court of Appeals vacated the District Court's consent judgment and remanded the case back to the District Court for further clarification. In August 2011, the District Court entered a stipulated judgment that we did not infringe the Jang patent. Dr. Jang filed an appeal on September 21, 2011 and on August 22, 2012, the Court of Appeals vacated the District Court's judgment and remanded the case to the District Court for further proceedings. On July 8, 2015, a jury found that our Express™ Stent family did not literally infringe a Jang patent, but that the stents infringed under the doctrine of equivalents. The court reserved judgment until the conclusion of further proceedings related to the doctrine of equivalents finding. On September 29, 2015, the court ruled that our Express™ Stent family did not infringe under the doctrine of equivalents and, on October 30, 2015, the court entered judgment in our favor. On November 25, 2015, Dr. Jang filed a motion for judgment as a matter of law on literal infringement and/or for a new trial. On February 3, 2016, the court denied Dr. Jang’s motion for a new trial and judgment as a matter of law. Dr. Jang filed a notice of appeal. On September 29, 2017, the U.S. Court of Appeals for the Federal Circuit affirmed the judgment that our Express Stent did not infringe the Jang patents and we did not owe Dr. Jang any payments. On October 30, 2017, Jang filed a petition for rehearing and on December 21, 2017 the rehearing was denied. On March 21, 2018, Jang filed a petition for United States Supreme Court review and, on October 1, 2018, the Supreme Court denied his petition.

The impact of stock options outstanding with exercise prices greater than the average fair market value of our common stock was immaterial for all periods presented.

We issued approximately two million shares of our common stock in the third quarter of 2018, two million shares of our common stock in the third quarter of 2017, 10 million shares of our common stock in the first nine months of2018 and 11 million shares of our common stock in the first nine months of2017, following the exercise of underlying stock options, vesting of deferred stock units or purchases under our employee stock purchase plan. We did not repurchase any shares of our common stock in the first nine 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 of segment net sales and operating income to include 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 unaudited condensed 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 Income (loss) before income taxes on the unaudited condensed consolidated statements of operations and are included in the reconciliation below.

30

Effective January 1, 2018, following organizational changes to align our 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 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.

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:

Emerging Markets (1)	$	263	$	236	$	794	$	671

(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 within Other current liabilities and Other long-term liabilities on our accompanying unaudited condensed consolidated balance sheets. Our deferred revenue balance was $378 million as of September 30, 2018 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. We recognized revenue of $27 million in the third quarter of 2018 and $80 million in the first nine months of2018 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.

33

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 reasonably estimate the expected rebates, we record a liability for the maximum rebate percentage offered. We have entered certain agreements with group purchasing organizations 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 unaudited condensed consolidated financial statements.

Refer to Note D – Hedging Activities and Fair Value Measurements for further detail on the reclassifications related to derivatives.

We adopted Update No. 2016-01 in the first quarter of 2018, and as a result of adopting the standard, we recorded a cumulative effect adjustment to retained earnings for unrealized gains and losses for available-for-sale securities previously recorded to Accumulated other comprehensive income (loss), net of tax.

The gains and losses on defined benefit and pension related items before reclassifications and gains and losses on defined benefit and pension items reclassified from Accumulated other comprehensive income (loss), net of tax were reduced by immaterial income tax impacts in the third quarter and first nine months of2018 and 2017.

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 liabilities on the balance sheet, including those previously classified as operating leases under current U.S. GAAP, and disclosing key information about leasing arrangements. Topic 842, as amended, is effective for annual periods beginning after December 15, 2018, including interim periods within those annual periods, with early adoption permitted.

We currently plan to adopt the standard using the transition method provided by ASC Update No. 2018-11, Leases (Topic 842): Targeted Improvements. Under this method, we plan to initially apply the new leasing rules on January 1, 2019, and recognize the cumulative effect of initially applying the standard as an adjustment to our opening balance of retained earnings, rather than at the earliest comparative period presented in the financial statements.

35

We have reached conclusions on several policy elections available under Topic 842 that we plan to apply on January 1, 2019. Upon transition, we will apply the package of practical expedients and will not reassess whether any expired or existing contracts are or contain leases, the classification of any expired or existing leases, and initial direct costs for any existing leases. We will apply the transition package of practical expedients described above to our entire lease portfolio at January 1, 2019. Furthermore, we have elected not to separate lease and non-lease components for the majority of our leases. Instead, for these applicable classes of underlying assets, we will account for each separate lease component, and the non-lease components associated with that lease component, as a single lease component.

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 on January 1, 2019. 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.

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.

ASC Update No. 2018-09

In July 2018, the FASB issued ASC Update No. 2018-09, Codification Improvements. The purpose of Update No. 2018-09 is to clarify, correct errors in or make minor improvements to the Codification. The amendments make the Codification easier to understand and apply by eliminating inconsistencies and providing clarifications. The transition and effective date guidance is based on the facts and circumstances of each amendment. Some of the amendments in Update No. 2018-09 do not require transition guidance and are effective upon issuance. However, many of the amendments in Update No. 2018-09 do have transition guidance with an effective date of 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.

ASC Update No. 2018-15

In August 2018, the FASB issued ASC Update No. 2018-15, Intangibles – Goodwill and Other – Internal-Use Software (Subtopic 350-40): Customer’s Accounting for Implementation Costs Incurred in a Cloud Computing Arrangement That Is a Service Contract. The purpose of Update No. 2018-15 is to align the requirements for capitalizing implementation costs incurred in a hosting arrangement that is a service contract with the requirements for capitalizing implementation costs incurred to develop or obtain internal-use software (and hosting arrangements that include an internal-use software license). Update No. 2018-15 is effective for annual periods beginning after December 15, 2019, including interim periods within those annual periods. Early adoption is permitted, including adoption in any interim period. 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, in the period had or are expected to have a material impact on our unaudited condensed consolidated financial statements.

Effective January 1, 2018, following organizational changes to align our 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.

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 $443 million represented approximately 19 percent of our consolidated net sales for the third quarter of 2018. Our Endoscopy net sales increased $40 million, or 10.1 percent, in the third quarter of 2018, as compared to the same period in the prior year. Our operational net sales, which exclude a 150 basis point impact of foreign currency fluctuations, increased 11.6 percent, as compared to the same period in the prior year. This year-over-year increase was primarily driven by growth in our hemostasis franchise featuring our Resolution 360™ Clips, our biliary franchise with both our SpyGlass™ DS Direct Visualization System and Acquire™ Endoscopic Ultrasound Fine Needle Biopsy Device, and our infection prevention products and pathology services.

Urology and Pelvic Health

Our Urology and Pelvic Health business develops and manufactures devices for treatment of various urological and pelvic conditions for both male and female anatomies, including kidney stones, benign prostatic hyperplasia (BPH), erectile dysfunction, male incontinence, pelvic floor disorders, abnormal uterine bleeding and uterine fibroids and polyps.

Our net sales of Urology and Pelvic Health products of $303 million represented approximately 13 percent of our consolidated net sales for the third quarter of 2018. Urology and Pelvic Health net sales increased $29 million, or 10.7 percent in the third quarter of 2018, as compared to the same period in the prior year. Our operational net sales, which exclude a 120 basis point impact of foreign currency fluctuations, increased 11.9 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 men's health products and our BPH business, including the Rezûm™ System purchased as part of our NxThera acquisition in the second quarter of 2018.

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 $475 million represented approximately 20 percent of our consolidated net sales for the third quarter of 2018. Our net sales of CRM products increased $11 million, or 2.3 percent, in the third quarter of 2018, as compared to the same period in the prior year. Our operational net sales, which exclude a 90 basis point impact of foreign currency fluctuations, increased 3.2 percent, as compared to the same period in the prior year. This year-over-year increase was primarily driven by strong growth across our defibrillator portfolio due to building momentum in the commercialization of our global RESONATE™ Cardiac Resynchronization Platform that includes our HeartLogic™ Heart Failure (HF) Diagnostic, the favorable impact of our U.S. magnetic resonance imaging (MRI) safe conditional labeling on our current generation of defibrillators, which launched in the fourth quarter of 2017, and the continued market penetration of our EMBLEM™ Subcutaneous Implantable Cardiac Defibrillator (S-ICD) System. Our defibrillator portfolio growth was partially offset by modest market share loss in our pacemaker portfolio.

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 $76 million represented approximately three percent of our consolidated net sales for the third quarter of 2018. Our Electrophysiology net sales increased $5 million, or 7.6 percent, in the third quarter of 2018, as compared to the same period in the prior year. Our operational net sales, which exclude a 100 basis point impact of foreign currency fluctuations, increased 8.6 percent, as compared to the same period in the prior year. This year-over-year increase was primarily driven by a continued global expansion of our next generation Rhythmia™ Mapping System, Rhythmia HDx™ Mapping System, along with Rhythmia-related therapeutic and diagnostic catheters, and accessories.

42

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 $189 million represented approximately eight percent of our consolidated net sales for the third quarter of 2018. Neuromodulation net sales increased $35 million, or 22.8 percent, in the third quarter of 2018, as compared to the same period in the prior year. Our operational net sales, which exclude a 70 basis point impact of foreign currency fluctuations, increased 23.5 percent, as compared to the same period in the prior year. This year-over-year increase was primarily driven by the launch of Spectra WaveWriter™ Spinal Cord Stimulator (SCS) Systems, the first U.S. Food and Drug Administration (FDA) approved system to simultaneously provide paresthesia-based and sub-perception therapy, and an increase in international sales.

Cardiovascular

Interventional Cardiology

Our Interventional Cardiology business develops and manufactures technologies for diagnosing and treating coronary artery disease and other cardiovascular disorders including structural heart conditions.

Our net sales of Interventional Cardiology products of $615 million represented approximately 26 percent of our consolidated net sales for the third quarter of 2018. Our Interventional Cardiology net sales increased $26 million, or 4.4 percent, in the third quarter of 2018, as compared to the same period in the prior year. Our operational net sales, which exclude a 190 basis point impact of foreign currency fluctuations, increased 6.3 percent, as compared to the same period in the prior year. This year-over-year increase was primarily driven by our structural heart therapies including WATCHMAN™ Left Atrial Appendage Closure (LAAC) Device, ACURATE™ Transcatheter Aortic Valve Replacement (TAVR) platform and Sentinel™ Cerebral Embolic Protection System purchased as part of our Claret acquisition in the third quarter of 2018. Sales of our complex percutaneous coronary interventions (PCI) product offerings also contributed to our growth, which was partially offset by declines in our drug-eluting coronary stent (DES) sales.

Peripheral Interventions

Our Peripheral Interventions business develops and manufactures products used to diagnose and treat peripheral arterial and venous 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 $293 million represented approximately 12 percent of our consolidated net sales for the third quarter of 2018. Our Peripheral Interventions net sales increased $25 million, or 9.2 percent, in the third quarter of 2018, as compared to the same period in the prior year. Our operational net sales, which exclude a 150 basis point impact of foreign currency fluctuations, increased 10.7 percent, as compared to the same period in the prior year. This year-over-year increase was primarily driven by strong performance in each region, particularly in Asia and Latin America, and growth in our interventional oncology product solutions, drug-eluting technologies, including Ranger™ Drug-Coated Balloon and Eluvia™ Drug Eluting Vascular Stent System, and core technologies to treat vascular diseases.

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 11.0 percent of our consolidated net sales in the third quarter of 2018 and 10.6 percent in the third quarter of 2017. In the third quarter of 2018, our Emerging Market net sales grew 11.1 percent on a reported basis and, excluding a 860 basis point impact of foreign currency fluctuations, grew 19.7 percent on an operational basis, both as compared to the same period in the prior year.

43

Gross Profit

Our Gross profit was $1.720 billion for the third quarter of 2018, $1.585 billion for the third quarter of 2017, $5.179 billion for the first nine months of2018 and $4.721 billion for the first nine months of2017. 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	Nine Months
Gross profit margin - period ended September 30, 2017	71.3%	71.1%
Manufacturing cost reductions	0.4	0.9
Sales pricing and mix	(0.2)	—
Net impact of foreign currency	(0.5)	(1.4)
All other, including inventory charges and other period expense	0.9	0.7
Gross profit margin - period ended September 30, 2018	71.9%	71.3%

The primary factors contributing to the increase in our gross profit margin in the third quarter and first nine months of2018, as compared to the same periods in 2017, were favorable period expenses compared to prior year, as well as the positive impacts of cost reductions resulting from our process improvement programs and restructuring programs, partially offset by negative impacts from foreign currency fluctuations.

Operating Expenses

The following table provides a summary of certain of our operating expenses:

	Three Months Ended September 30,								Nine Months Ended September 30,
	2018				2017				2018				2017
(in millions)	$		% of Net Sales		$		% of Net Sales		$		% of Net Sales		$		% of Net Sales
SG&A expenses	$	870	36.4	%	$	800	36.0	%	$	2,616	36.0	%	$	2,408	36.3	%
R&D expenses	289		12.1	%	254		11.4	%	825		11.4	%	734		11.0	%
Royalty expense	17		0.7	%	16		0.7	%	52		0.7	%	50		0.8	%

Selling, General and Administrative (SG&A) Expenses

In the third quarter of 2018, our SG&A expensesincreased$70 million, or nine percent, as compared to the third quarter of 2017, and were 40basis points higher as a percentage of net sales due to the reduced SG&A expenses in the prior year period. In the first nine months of2018, our SG&A expensesincreased $208 million, or nine percent, as compared to the first nine months of2017 and were 30basis points lower as a percentage of net sales. The decrease in SG&A expenses during 2018 as a percentage of net sales was primarily driven by the benefit of our targeted initiatives focused on reducing SG&A expenses, 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 third quarter of 2018, our R&D expensesincreased $35 million, or 14 percent, as compared to the third quarter of 2017, and were 70basis points higher as a percentage of net sales. In the first nine months of2018, our R&D expensesincreased $92 million, or 13 percent, as compared to the first nine months of2017, and were 40basis points higher as a percentage of net sales. R&D expensesincreased 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 $17 million in the third quarter of 2018, $16 million in the third quarter of 2017, $52 million in the first nine months of2018 and $50 million in the first nine months of2017. Our Royalty expense remained relatively flat at approximately one percent of net sales in the third quarter and the first nine months of2018 and 2017.

Amortization Expense

Our Amortization expense was $148 million in the third quarter of 2018, $139 million in the third quarter of 2017, $437 million in the first nine months of2018 and $424 million in the first nine months of2017. The increase in Amortization expense in each period was primarily due to amortizable intangible assets obtained as part of our recent acquisitions. Amortization expense is excluded by management for purposes of evaluating operating performance.

Intangible Asset Impairment Charges

Our Intangible asset impairment charges were $3 million in the third quarter of 2017, $35 million in the first nine months of2018 and $3 million in the first nine months of2017 relating to impairment of technology-related intangible assets. Intangible asset impairment charges are excluded by management for purposes of evaluating operating performance.

Contingent Consideration Expense (Benefit)

Our contingent consideration benefit was $13 million in the third quarter of 2018, $4 million in the third quarter of 2017, $12 million in the first nine months of2018 and $78 million in the first nine months of2017 related to the change in fair value of our contingent consideration liability. Refer to 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 additional details related to our contingent consideration expenses. Contingent consideration expense (benefit) is excluded by management for purposes of evaluating operating performance.

Restructuring and Restructuring-related Activities

The following table provides a summary of our restructuring and restructuring-related charges:

Restructuring-related charges (credits)	12		14		38		44

Restructuring and restructuring-related charges and credits are excluded by management for purposes of evaluating operating performance.

The 2016 Restructuring Plan is expected to result in total pre-tax charges of approximately $275 million to $325 million and reduce gross annual expenses by approximately $165 million to $175 million by the end of 2020 as plan benefits are realized. A substantial portion of these savings will be reinvested in strategic growth initiatives.

In association with our 2016 Restructuring Plan, we have made cumulative cash payments of $172 million as of September 30, 2018.

Refer to Note F – Restructuring-related Activities to our unaudited condensed consolidated financial statements contained in Item 1 of this Quarterly Report on Form 10-Q for additional details related to our restructuring plans.

Other income (expense), net	(4		)	(4		)	(6		)	(17		)
	$	126		$	(11	)	$	116		$	(89	)

We recorded gains of $142 million in the third quarter of 2018 and $182 million in the first nine months of 2018 based on the difference between the book values and the fair values of our previously-held investments immediately prior to the acquisition dates, which aggregate to $250 million. We remeasured the fair value of each previously-held investment based on the implied enterprise value and allocation of purchase price consideration according to priority of equity interests. Gains recorded on previously-held investments are excluded by management for purposes of evaluating operating performance.

Tax Rates

Our effective tax rate from continuing operations is presented below:

	Three Months Ended September 30,				Nine Months Ended September 30,
	2018		2017		2018		2017
Effective tax rate from continuing operations	5.3	%	8.5	%	(14.1	)%	(2.0	)%

The change in our reported tax rates for the third quarter and the first nine months of 2018, as compared to the same periods in 2017, relates primarily to the impact of certain receipts and charges that are taxed at different rates than our effective tax rate. These receipts and charges include intangible asset impairment charges, acquisition-related items, restructuring items, litigation-related items, as well as certain discrete tax items including the effective settlement of our transfer pricing dispute with the Internal Revenue Service (IRS) for the 2001 through 2010 tax years and the impacts of the Tax Cuts and Jobs Act (TCJA), enacted on December 22, 2017.

In the second quarter of 2018, a decision was entered by the United States Tax Court resolving all disputes related to the transfer pricing issues for Guidant Corporation's 2001 through 2006 tax years and our 2006 and 2007 tax years as well as the tax issues related to our 2006 transaction with Abbott Laboratories. Additionally, we resolved all issues with the IRS Office of Appeals for our 2008 through 2010 tax years, including the transfer pricing issue and other unrelated issues. The final settlement calculation included certain elections made in these relevant years and resulted in a final net tax payment of $303 million plus $307 million of estimated interest, which was remitted in the second quarter of 2018. Due to the final settlement of these disputes, we recorded a net tax benefit of $250 million in the first nine months of2018.

46

We currently expect to resolve the IRS examination of our 2011 through 2013 tax years in the next six months. We expect that the exam will be concluded utilizing the same transfer pricing methodologies employed in the 2001 through 2010 tax years. We believe we have recorded sufficient reserves with respect to these periods and therefore do not expect to recognize any additional charges related to the resolution of the 2011 through 2013 tax years.

Refer to Note H – Income Taxesto 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 nine months endedSeptember 30, 2018, there were no changes to the application of critical accounting policies previously disclosed in our most recent Annual Report on Form 10-K with the exception of our critical accounting policies related to the adoption of FASB ASC Topic 606, Revenue from Contracts with Customers effective 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 SG&A 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 to our unaudited condensed consolidated financial statements contained in Item 1 of this Quarterly Report on Form 10-Q 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 litigation-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 September 30, 2018, we had $168 million of Cash and cash equivalents on hand, comprised of $30 million invested in money market and government funds and $138 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 access to our $2.250 billion commercial paper program, which is backed by our 2017 revolving credit facility described below. As of September 30, 2018, we had $816 million in commercial paper debt outstanding resulting in an additional $1.434 billion of available liquidity and no amounts outstanding on our credit facility secured by our U.S. trade receivables resulting in an additional $400 million of available liquidity, as described below.

The following provides a summary and description of our net cash inflows (outflows):

	Nine Months Ended September 30,
(in millions)	2018			2017

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

Revolving Credit Facility

As of September 30, 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 outstanding under our revolving credit facility as of September 30, 2018 andDecember 31, 2017.

48

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

	Covenant Requirement	Actual
	as of September 30, 2018	as of September 30, 2018
Maximum leverage ratio (1)	3.5 times	2.4 times

(1) Ratio of total debt to consolidated EBITDA, as defined by the 2017 Facility, 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 September 30, 2018, we had $386 millionof 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 September 30, 2018, we had $1.384 billionof 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.

Commercial Paper

As of September 30, 2018, we had $816 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 September 30, 2018, the commercial paper issued and outstanding had a weighted average maturity of 29days and a weighted average yield of2.58 percent. As of December 31, 2017, the commercial paper issued and outstanding had a weighted average maturity of 38days and a weighted average yield of1.85 percent.

Senior Notes

We had senior notes outstanding of $4.800 billion as ofSeptember 30, 2018 and$4.400 billionas ofDecember 31, 2017.

In February 2018, we completed an offering of$1.000 billion in aggregate principal amount of4.000%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 our2.650%senior notes due in October 2018. The remaining proceeds were used to repay a portionof 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).

Term Loan

On August 20, 2018, we entered into a $1.000 billion Term Loan Credit Agreement (August 2019 Term Loan), maturing on August 19, 2019, which is presented within Current debt obligations in the accompanying unaudited condensed consolidated balance sheets. Borrowings under the August 2019 Term Loan bear interest at an annual rate of LIBOR plus 0.65%. The August 2019 Term Loan requires that we comply with certain covenants, including financial covenants with respect to maximum leverage consistent with the 2017 Facility. As of September 30, 2018, we had $1.000 billion outstanding under our August 2019 Term Loan. We used the proceeds from the August 2019 Term Loan to repay a portion of our outstanding commercial paper.

Other Arrangements

As of September 30, 2018 and December 31, 2017, we maintained a $400 millioncredit and security facility secured by our U.S. trade receivables maturing in February 2019.We had no outstanding borrowings as of September 30, 2018and December 31, 2017 under our credit and security facility.

49

We have accounts receivable factoring programs in certain European countries and with commercial banks in Japan which include promissory notes discounting programs. We account for our factoring programs as sales under FASB ASC Topic 860, Transfers and Servicing. We have no retained interest in the transferred receivables, other than collection and administration, and once sold, the accounts receivable are no longer available to satisfy creditors in the event of bankruptcy. Amounts de-recognized for accounts and notes receivable, which are excluded from Trade accounts receivable, net in the accompanying unaudited condensed consolidated balance sheets, are aggregated by contract denominated currency below (in millions):

	As of September 30, 2018						As of December 31, 2017
Factoring Arrangements	Capacity (1)		Amount De-recognized		Average Interest Rate		Capacity (1)		Amount De-recognized		Average Interest Rate
Euro denominated	$	451	$	158	1.7	%	$	456	$	171	1.8	%
Yen denominated (2)	458		194		0.5	%	195		157		1.3	%

(1) The capacities are translated from local currency to U.S. dollar using the spot rates on the last business day of each period.

(2) The factoring arrangements denominated in Japanese yen consist of two arrangements, one with a maximum capacity of 22.000 billionyen, which has been discontinued in 2018, and a new arrangement with a maximum capacity of 30.000 billion yen entered into in March 2018.

As of and through September 30, 2018, we were in compliance with all the required covenants related to our debt obligations.

Equity

We received $94 million in the first nine months of 2018 and $79 million in the first nine 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.

We did not repurchase any shares of our common stock in the first nine months of 2018 and 2017. As of September 30, 2018, the remaining authorization to repurchase shares under our 2013 share repurchase program was $535 million.

Contractual Obligations and Commitments

Certain of our acquisitions involve the payment of contingent consideration. See Note B – Acquisitions and Strategic Investmentsto 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.

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

Cybersecurity

We have established controls and procedures to escalate enterprise level issues, including cybersecurity matters, to the appropriate management levels within our organization and to members of our Board of Directors as appropriate. Under our framework, cybersecurity issues are analyzed by subject matter experts and a crisis committee for potential financial, operational, and reputational risks, based on, among other factors, the nature of the matter and breadth of impact. Matters determined to present potential material impacts to the Company’s financial results, operations, and/or reputation are immediately reported by

50

management to one or more members of the Board of Directors in accordance with our escalation framework. In addition, we have established procedures to ensure that management responsible for overseeing the effectiveness of disclosure controls is informed in a timely manner of known cybersecurity risks and incidents that may materially impact our operations and that timely public disclosure is made as appropriate. 

Our directors and executive officers are subject to our Stock Trading Policy, which is designed to facilitate compliance with insider trading laws and governs transactions in our common stock and related derivative securities. Our policy designates certain regular periods, dictated by release of financial results, in which trading is restricted for individuals in information-sensitive positions, including directors and executive officers. In addition, additional periods of trading restriction may be imposed as determined by the President, General Counsel, or Chief Financial Officer in light of material pending developments. Further, during permitted windows, individuals in information-sensitive positions are required to seek pre-clearance for trades from the General Counsel, who assesses whether there are any important pending developments, including cybersecurity matters, which need to be made public before the individual may participate in the market.

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. Amounts are tax effected at our effective tax rate, unless the amount is a significant unusual or infrequently occurring item in accordance with FASB ASC Topic 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 (SEC) for an explanation of each of these adjustments and the reasons for excluding each item. The following is an explanation of each incremental or revised adjustment type that management excluded as part of these non-GAAP financial measures, since our most recent Annual Report on Form 10-K, as well as the reason for excluding each individual item:

• Discrete tax items - These items represent adjustments of certain tax positions including those which a) are estimates as a result of the TCJA, enacted in December 2017, and, or b) were a benefit resulting from the finalization of the IRS Stipulation of Settled Issues consistent with the manner in which the tax reserves were originally booked. These adjustments are not indicative of expected ongoing operating results. We exclude the impact of this charge from management's assessment of operating performance and from our operating segments' measures of profit and loss used for making operating decisions and assessing performance. Accordingly, management excluded these amounts for the purposes of calculating these non-GAAP financial measures to facilitate an evaluation of our current operating performance and a comparison to our past operating performance.

The GAAP financial measures most directly comparable to adjusted net income and adjusted net income per share are 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 in Item 2 of this Quarterly Report on Form 10-Q beginning with our Financial Summary.

51

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.

55

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 $8.374 billion as of September 30, 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 $451 million as of September 30, 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 $551 million as of September 30, 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 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 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 September 30, 2018 and December 31, 2017. As of September 30, 2018, $4.800 billion of our outstanding debt obligations were at fixed interest rates, representing approximately 72 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.

56

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 September 30, 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 September 30, 2018, our disclosure controls and procedures were effective.

Changes in Internal Control Over Financial Reporting

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 in the three and nine month period ended September 30, 2018 that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

Organization, Consolidation and Presentation of Financial Statements [Abstract]

BASIS OF PRESENTATION

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. When used in this report, the terms, "we," "us," "our," and "the Company" mean Boston Scientific Corporation and its divisions and subsidiaries. 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 and nine months ended September 30, 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 our 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 sheet 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 and nine months ended September 30, 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 FASB ASC Topic 606, 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 retained earnings of $177 million on January 1, 2018, primarily related to the cost of providing non-contractual post-implant support to certain customers, which we historically 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 resulted in an increase in Other current liabilities of $59 million and an increase in Other long-term liabilities of $205 million as of September 30, 2018, 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 $41 million as of September 30, 2018. 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 (loss) were reclassified to retained earnings,and all future fair value changes will be recorded to Net income (loss). For privately-held securities, we elected the measurement alternative approach for our existing investments, 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 (benefit).

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.

In addition, we completed other individually immaterial acquisitions in the first nine months of2018 for total consideration of $50 million in cash at closing plus aggregate contingent consideration of up to $10 million.

We recorded gains of $142 million in the third quarter of 2018 and $182 million in the first nine months of 2018 within Other, net on our unaudited condensed consolidated statements of operations based on the difference between the book values and the fair values of our previously-held investments immediately prior to the acquisition dates, which aggregate to $250 million.

2017 Acquisitions

Symetis SA

On May 16, 2017, we announced the closing of our acquisition of Symetis SA (Symetis), a privately-held Swiss structural heart company focused on minimally-invasive transcatheter aortic valve replacement devices. The transaction price consists of an upfront cash payment of approximately $430 million. We are in the process of integrating Symetis into our Interventional Cardiology business.

Purchase Price Allocation

We accounted for the acquisition of Symetis as a business combination, and in accordance with FASB ASC Topic 805, we recorded the assets acquired and liabilities assumed at their respective fair values as of the acquisition date. The purchase price was comprised of the following component:

(in millions)
Payment for acquisition, net of cash acquired	$	391

The following summarizes the purchase price allocation for the Symetis acquisition as of September 30, 2018:

(in millions)
Goodwill	$	183
Amortizable intangible assets	278
Other assets acquired	25
Liabilities assumed	(95		)
	$	391

We allocated a portion of the purchase price to specific intangible asset categories as follows:

	Amount Assigned (in millions)		Amortization Period (in years)	Risk-Adjusted Discount Rates used in Purchase Price Allocation
Amortizable intangible assets:
Technology-related	$	268	13	24%
Other intangible assets	10		2 - 13	24%
	$	278

Our technology-related intangible assets consist of technical processes, intellectual property and institutional understanding with respect to products and processes that we will leverage in future products or processes and will carry forward from one product generation to the next. We used the multi-period excess earnings method, a form of the income approach, to derive the fair value of the technology-related intangible assets and are amortizing them on a straight-line basis over their assigned estimated useful lives.

Goodwill was primarily established due to synergies expected to be gained from leveraging our existing operations as well as revenue and cash flow projections associated with future technologies and has been allocated to our reportable segments based on the relative expected benefit. Based on preliminary estimates updated for applicable regulatory changes, the goodwill recorded relating to our 2018 and 2017 acquisitions is not deductible for tax purposes.

Our IPR&D intangible assets that are not subject to amortization (indefinite-lived intangible assets) represent technical processes, intellectual property and/or institutional understanding acquired through business combinations that are fundamental to the ongoing operations of our business and have no limit to their useful life.

Contingent Consideration

Changes in the fair value of our contingent consideration liability were as follows:

(in millions)
Balance as of December 31, 2017	$	169
Amounts recorded related to current year acquisitions	190
Purchase price adjustments related to prior year acquisitions	(22		)
Contingent consideration expense (benefit)	(12		)
Contingent consideration payments	(21		)
Balance as of September 30, 2018	$	305

As of September 30, 2018, the maximum amount of future contingent consideration (undiscounted) that we could be required to pay was approximately $780 million. The maximum amount of future contingent consideration (undiscounted) decreased approximately $540 million compared to the amount as of December 31, 2017 due primarily to the expiration of certain contingent consideration arrangements in the third quarter of 2018.

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

Contingent Consideration Liability	Fair Value as of September 30, 2018	Valuation Technique	Unobservable Input	Range
R&D, Regulatory and Commercialization-based Milestones	$201 million	Discounted Cash Flow	Discount Rate	3	%	-	4%
			Probability of Payment	17	%	-	99%
			Projected Year of Payment	2018		-	2022
Revenue-based Payments	$104 million	Discounted Cash Flow	Discount Rate	11	%	-	15%
			Projected Year of Payment	2018		-	2026

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

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 an additional $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)	September 30, 2018		December 31, 2017
Equity method investments	$	291	$	209
Measurement alternative investments	73		81
Publicly-held securities	1		15
Notes receivable	19		47
	$	384	$	353

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 September 30, 2018, the carrying amount of our aggregated equity method investments exceeded our share of the underlying equity in net assets by approximately $321 million, which represents amortizable intangible assets, IPR&D, deferred tax liabilities and goodwill.

Goodwill and Indefinite-Lived Intangible Asset Impairment Testing

We test our goodwill balances in the second quarter of each year for impairment, or more frequently if impairment indicators are present or changes in circumstances suggest an impairment may exist. In the second quarter of 2018, we performed our annual goodwill impairment test for all of our reporting units and concluded the fair value of each reporting unit exceeded its carrying value.

In performing the goodwill impairment assessment, we utilized both the optional qualitative assessment and the quantitative approach prescribed under FASB ASC Topic 350, Intangibles - Goodwill and Other. In 2018, we performed a qualitative assessment for our Urology and Pelvic Health and Neuromodulation reporting units since their fair values have historically exceeded carrying value by greater than 100 percent. The remaining reporting units were quantitatively tested for impairment. For the reporting units subject to a qualitative assessment, if it is determined that it is more likely than not that the fair value of the reporting unit is less than its carrying value, the quantitative approach of the goodwill impairment test is necessary. In 2018, for all reporting units tested using the qualitative assessment, we concluded that it was unnecessary to perform the quantitative impairment test. For all reporting units tested using the quantitative approach, we concluded that the fair value of each reporting unit exceeded its carrying value.

In the third quarter of 2018, we performed our annual impairment test of all IPR&D projects and our indefinite-lived core technology assets using the optional qualitative assessment approach and determined that there were no impairment indicators. In addition, we verified that their classification as indefinite-lived assets continues to be appropriate.

Refer to Critical Accounting Policies and Estimates within Part II, Item 7. Management's Discussion and Analysis of Financial Condition and Results of Operations contained in our most recent Annual Report on Form 10-K for further discussion of our annual goodwill and indefinite-lived intangible asset impairment testing.

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 to material risk, as the gains or losses on these derivatives generally offset losses or gains recognized on the hedged item.

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 (loss), net of tax (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 in 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, which 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.

Certain of our currency forward contracts are designated as net investment hedges under FASB ASC Topic 815 and are intended to hedge a portion of our net investments in certain of our entities with functional currencies denominated in Euro, Swiss franc, and Japanese yen functional operating entities. We have elected to use the spot method to assess effectiveness for our derivatives that are designated as net investment hedges. Under the spot method, the change in fair value attributable to changes in the spot rate is recorded in the Foreign currency translation adjustment (CTA), which is included within the AOCI caption of our unaudited condensed consolidated balance sheets. Therefore, the spot-forward difference is excluded from the assessment of effectiveness and accounted for separately.

Consistent with FASB ASC Topic 815, we have elected to amortize the excluded spot-forward difference associated with the currency forward contracts as calculated at the date of designation. Amortization will be recognized on a straight-line basis over the term of the currency forward contracts from the AOCI caption of our unaudited condensed consolidated balance sheets to reported earnings as a reduction of Interest expense.

The following table presents the contractual amounts of our derivative instruments outstanding:

(in millions)	FASB ASC Topic 815 Designation	As of

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 and 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
(in millions)		September 30, 2018		December 31, 2017
Derivative Assets:
Designated Derivative Instruments
Forward currency contracts	Other current assets	$	48	$	7
Forward currency contracts	Other long-term assets	147		57
		195		64
Non-Designated Derivative Instruments
Forward currency contracts	Other current assets	61		18
Total Derivative Assets		$	256	$	82
Derivative Liabilities:

Forward currency contracts	Other current liabilities	$	5	$	37
Forward currency contracts	Other long-term liabilities	10		33
		14		69
Non-Designated Derivative Instruments
Forward currency contracts	Other current liabilities	29		21
Total Derivative Liabilities		$	44	$	90

(1) We classify derivative assets and liabilities as current when the settlement date 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:

	As of
	September 30, 2018								December 31, 2017
(in millions)	Level 1		Level 2		Level 3		Total		Level 1		Level 2		Level 3		Total

	$	—	$	44	$	305	$	349	$	—	$	90	$	169	$	259

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 $30 million invested in money market and government funds as of September 30, 2018, we had $138 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 Level 3 inputs relate solely to our contingent consideration liability. Refer to Note B – Acquisitions and Strategic Investmentsfor 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.

The fair value of our outstanding debt obligations was $6.821 billion as of September 30, 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.

Maximum leverage ratio (1)	3.5 times	2.4 times

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 September 30, 2018, we had $386 millionof 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 September 30, 2018, we had $1.384 billionof 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.

Commercial Paper

As of September 30, 2018, we had $816 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 September 30, 2018, the commercial paper issued and outstanding had a weighted average maturity of 29days and a weighted average yield of2.58 percent. As of December 31, 2017, the commercial paper issued and outstanding had a weighted average maturity of 38days and a weighted average yield of1.85 percent.

Senior Notes

We had senior notes outstanding of $4.800 billion as ofSeptember 30, 2018 and$4.400 billionas ofDecember 31, 2017.

In February 2018, we completed an offering of$1.000 billion in aggregate principal amount of4.000%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 our2.650%senior notes due in October 2018. The remaining proceeds were used to repay a portionof 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).

Term Loan

On August 20, 2018, we entered into a $1.000 billion Term Loan Credit Agreement (August 2019 Term Loan), maturing on August 19, 2019, which is presented within Current debt obligations in the accompanying unaudited condensed consolidated balance sheets. Borrowings under the August 2019 Term Loan bear interest at an annual rate of LIBOR plus 0.65%. The August 2019 Term Loan requires that we comply with certain covenants, including financial covenants with respect to maximum leverage consistent with the 2017 Facility. As of September 30, 2018, we had $1.000 billion outstanding under our August 2019 Term Loan. We used the proceeds from the August 2019 Term Loan to repay a portion of our outstanding commercial paper.

Other Arrangements

As of September 30, 2018 and December 31, 2017, we maintained a $400 millioncredit and security facility secured by our U.S. trade receivables maturing in February 2019.We had no outstanding borrowings as of September 30, 2018and December 31, 2017 under our credit and security facility.

We have accounts receivable factoring programs in certain European countries and with commercial banks in Japan which include promissory notes discounting programs. We account for our factoring programs as sales under FASB ASC Topic 860, Transfers and Servicing. We have no retained interest in the transferred receivables, other than collection and administration, and once sold, the accounts receivable are no longer available to satisfy creditors in the event of bankruptcy. Amounts de-recognized for accounts and notes receivable, which are excluded from Trade accounts receivable, net in the accompanying unaudited condensed consolidated balance sheets, are aggregated by contract denominated currency below (in millions):

	As of September 30, 2018						As of December 31, 2017

Debt Covenants Compliance

As of and through September 30, 2018, we were in compliance with all the required covenants related to our debt obligations.

Restructuring and Related Activities [Abstract]

RESTRUCTURING-RELATED ACTIVITIES

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 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. The majority of the costs associated with this Plan are expected to be incurred 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	$80 million to $90 million
Other (1)	$25 million to $50 million
Restructuring-related expenses:
Other (2)	$170 million to $185 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, fixed asset write-offs and costs to transfer product lines among facilities.

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

INCOME TAXES

NOTE H – INCOME TAXES

Our effective tax rate from continuing operations is presented below:

	Three Months Ended September 30,				Nine Months Ended September 30,
	2018		2017		2018		2017
Effective tax rate from continuing operations	5.3	%	8.5	%	(14.1	)%	(2.0	)%

The change in our reported tax rates for the third quarter and the first nine months of 2018, as compared to the same periods in 2017, relates primarily to the impact of certain receipts and charges that are taxed at different rates than our effective tax rate. These receipts and charges include intangible asset impairment charges, acquisition-related items, restructuring items, litigation-related items, as well as certain discrete tax items including the effective settlement of our transfer pricing dispute with the Internal Revenue Service (IRS) for the 2001 through 2010 tax years and the impacts of the Tax Cuts and Jobs Act (TCJA), enacted on December 22, 2017.

In the second quarter of 2018, a decision was entered by the United States Tax Court resolving all disputes related to the transfer pricing issues for Guidant Corporation's 2001 through 2006 tax years and our 2006 and 2007 tax years as well as the tax issues related to our 2006 transaction with Abbott Laboratories. Additionally, we resolved all issues with the IRS Office of Appeals for our 2008 through 2010 tax years, including the transfer pricing issue and other unrelated issues. The final settlement calculation included certain elections made in these relevant years and resulted in a final net tax payment of $303 million plus $307 million of estimated interest, which was remitted in the second quarter of 2018. Due to the final settlement of these disputes, we recorded a net tax benefit of $250 million in the first nine months of2018.

We currently expect to resolve the IRS examination of our 2011 through 2013 tax years in the next six months. We expect that the exam will be concluded utilizing the same transfer pricing methodologies employed in the 2001 through 2010 tax years. We believe we have recorded sufficient reserves with respect to these periods and therefore do not expect to recognize any additional charges related to the resolution of the 2011 through 2013 tax years.

As of September 30, 2018, we had $511 million of gross unrecognized tax benefits, of which a net $438 million, 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. The change in our gross unrecognized tax benefit is primarily related to reaching settlements with tax authorities.

We recognize interest and penalties related to income taxes as a component of income tax expense. We had $81 million accrued for gross interest and penalties as of September 30, 2018 and $655 million as of December 31, 2017. The change in our accrued interest and penalties is primarily related to reaching settlements with tax authorities. We recognized net tax expense related to interest and penalties of $3 million in the third quarter of 2018, $14 million in the third quarter of 2017, $22 million in the first nine months of2018 and $40 million in the first nine months of2017.

It is reasonably possible that within the next 12 months we will resolve multiple 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 $226 million.

There are a number of key provisions under the TCJA that impact us and we continue to monitor and analyze the ramifications 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 U.S. 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. We have not recognized any additional tax in the third quarter of 2018, but we will continue to analyze the TCJA impact in the fourth quarter. In the first nine months of2018, we recognized an additional tax benefit of $37 million related to settling our transfer pricing dispute with the IRS, resulting in a total provisional estimate of $824 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 September 30, 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 subsidiaries' earnings and profits (E&P) that we previously deferred from U.S. income taxes. As a result of settling our various tax audits, the revised provisional amount of transition tax is approximately $866 million. We anticipate offsetting this liability against existing tax attributes reducing the required payment to approximately $506 million, which will be remitted over an eight-year period. We remitted the first estimated installment payment in the second quarter of 2018. We have not yet completed our calculation of the total post-1986 E&P, and we continue to refine the analysis. We expect that our undistributed foreign earnings as of December 31, 2017 will remain indefinitely reinvested in our foreign operations. Accordingly, no income taxes beyond the federal and state impact of the transition tax have been provided for these undistributed foreign earnings or any additional outside basis difference inherent in these entities. Determining the amount of unrecognized deferred tax liability related to any remaining undistributed foreign earnings 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 September 30, 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, Securities and Exchange Commission (SEC) Staff Accounting Bulletin (SAB) No. 118 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.

Commitments and Contingencies Disclosure [Abstract]

COMMITMENTS AND CONTINGENCIES

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.

Our accrual for legal matters that are probable and estimable was $1.162 billion as of September 30, 2018 and $1.612 billion as of December 31, 2017 and includes certain estimated costs of settlement, damages and defense. The decrease in our legal accrual was primarily due to settlement payments, authorized in 2018, associated with product liability cases or claims related to transvaginal surgical mesh products. A portion of our legal accrual is funded and included in our restricted cash and restricted cash equivalent balances of $812 million as of September 30, 2018 and $829 million as of December 31, 2017, as disclosed in Note G – Supplemental Balance Sheet Information. We recorded litigation-related net charges of $18 million in the third quarter and first nine months of2018. We recorded a litigation-related net credit of $12 million in the third quarter of 2017 and a litigation-related net charge of $196 million in the first nine months of2017. 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, our Quarterly Report on Form 10-Q for the periods ended March 31, 2018 and June 30, 2018 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 April 19, 2016, a subsidiary of Boston Scientific filed suit against Edwards Lifesciences Corporation (Edwards) 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 our patent invalid. The Company filed an appeal before the United States Court of Appeals for the Federal Circuit on May 24, 2018.

On November 29, 2016, Nevro Corp. (Nevro) filed a patent infringement action against us and one of our subsidiaries, Boston Scientific Neuromodulation Corporation, in the U.S. District Court for the Northern District of California alleging that six U.S. patents (Alataris) owned by Nevro are infringed by our spinal cord stimulation systems. On June 29, 2017, Nevro amended the complaint to add an additional patent (Fang). We deny the plaintiff's allegations and intend to defend ourselves vigorously. On July 24, 2018, summary judgment was entered in favor of the Company and on July 31, 2018, we received final judgment and dismissal of the action. On July 31, 2018, Nevro filed an appeal.

On August 1, 2018, the Company filed a patent infringement action on the merits in Dusseldorf, Germany against Edwards Lifesciences Corporation and Edwards Lifesciences GmbH (collectively Edwards) alleging that the Sapien 3^™ device and Sapien 3 Ultra™ device infringed a patent owned by the Company.

On August 3, 2018, the Company filed a preliminary injunction request in Dusseldorf, Germany against Edwards Lifesciences Corporation and Edwards Lifesciences GmbH (collectively Edwards) alleging that the Sapien 3 Ultra infringed a patent owned by the Company. On October 23, 2018, the court found that the Sapien 3 Ultra infringed the patent. Edwards has the right to appeal.

On April 21, 2018, the Company and Boston Scientific Neuromodulation Corporation filed a patent infringement, theft of trade secrets and tortious interference with a contract action against Nevro Corp. in U.S. District Court for the District of Delaware, and amended the complaint on July 18, 2018, alleging that nine U.S. patents owned by Boston Scientific Neuromodulation Corporation are infringed by Nevro’s Senza™ I and Senza™ II Spinal Cord Stimulation Systems.

On August 22, 2018, Edwards Lifesciences LLC filed a patent infringement action against Boston Scientific Corporation, in the U. S. District Court of Delaware, alleging that two U.S. patents (Schweich) owned by them are infringed by our Watchman™ Left Atrial Appendage Closure Device, Watchman Delivery System and Watchman Access System.

Product Liability Litigation

No individual lawsuits remain pending in state court jurisdictions against Guidant, alleging personal injuries associated with defibrillators or pacemakers involved in certain 2005 and 2006 product communications. Further, we are aware of approximately six Guidant product liability lawsuits pending in international jurisdictions associated with defibrillators or pacemakers, including devices involved in the 2005 and 2006 product communications. Four of these suits are pending in Canada involving certain models of Guidant pacemakers, three of which are stayed pending the outcome of one lead class action. On May 8, 2009, the Justice of Ontario Court certified a class of persons in whom pacemakers were implanted in Canada and a class of family members with derivative claims. In each case, these matters generally seek monetary damages from us. This class action has been inactive since 2011. On March 24, 2014, the Ontario Superior Court approved a $3 million settlement of a class action involving certain models of Guidant defibrillators. We believe Guidant has satisfied its obligations pursuant to the settlement agreement.

As of October 23, 2018, approximately 51,000 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 U.S. and include eight putative class actions. There were also fewer than 25 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 U.S. 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 October 23, 2018, we have entered into master settlement agreements in principle or are in the final stages of entering one with certain plaintiffs' counsel to resolve an aggregate of approximately 49,500 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 49,500 cases and claims, approximately 30,000 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.

Other Proceedings

On September 12, 2018, Channel Medsystems, Inc. (Channel) filed a complaint in Delaware Chancery Court against us for alleged breach of a $275 million purchase agreement. Channel alleges that we breached the agreement by terminating it. We have answered the complaint, deny the claims by Channel and have counterclaimed to recover part of our investment in Channel, alleging fraud in the inducement. The court has set a trial date of April 15, 2019.

Matters Concluded Since December 31, 2017

On October 28, 2016, the Regents of the University of California filed a patent infringement action against us in the U.S. District Court for the Northern District of California alleging that two U.S. patents (Lesh) owned by the Regents of the University of California are infringed by certain of our catheters and other devices used to treat atrial fibrillation. The Company and the Regents settled the matter, and the case was dismissed on June 20, 2018.

On May 19, 2005, G. David Jang, M.D. filed suit against us alleging breach of contract relating to certain patent rights covering stent technology. The suit was filed in the U.S. District Court for the Central District of California seeking monetary damages and rescission of contract. After a Markman ruling relating to the Jang patent rights, Dr. Jang stipulated to the dismissal of certain claims alleged in the complaint with a right to appeal and the parties subsequently agreed to settle the other claims. In May 2007, Dr. Jang filed an appeal with respect to the remaining patent claims and in July 2008, the Court of Appeals vacated the District Court's consent judgment and remanded the case back to the District Court for further clarification. In August 2011, the District Court entered a stipulated judgment that we did not infringe the Jang patent. Dr. Jang filed an appeal on September 21, 2011 and on August 22, 2012, the Court of Appeals vacated the District Court's judgment and remanded the case to the District Court for further proceedings. On July 8, 2015, a jury found that our Express™ Stent family did not literally infringe a Jang patent, but that the stents infringed under the doctrine of equivalents. The court reserved judgment until the conclusion of further proceedings related to the doctrine of equivalents finding. On September 29, 2015, the court ruled that our Express™ Stent family did not infringe under the doctrine of equivalents and, on October 30, 2015, the court entered judgment in our favor. On November 25, 2015, Dr. Jang filed a motion for judgment as a matter of law on literal infringement and/or for a new trial. On February 3, 2016, the court denied Dr. Jang’s motion for a new trial and judgment as a matter of law. Dr. Jang filed a notice of appeal. On September 29, 2017, the U.S. Court of Appeals for the Federal Circuit affirmed the judgment that our Express Stent did not infringe the Jang patents and we did not owe Dr. Jang any payments. On October 30, 2017, Jang filed a petition for rehearing and on December 21, 2017 the rehearing was denied. On March 21, 2018, Jang filed a petition for United States Supreme Court review and, on October 1, 2018, the Supreme Court denied his petition.

Segment Reporting [Abstract]

SEGMENT REPORTING

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 of segment net sales and operating income to include 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 unaudited condensed 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 Income (loss) before income taxes on the unaudited condensed consolidated statements of operations and are included in the reconciliation below.

Effective January 1, 2018, following organizational changes to align our 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 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.

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:

Emerging Markets (1)	$	263	$	236	$	794	$	671

(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 within Other current liabilities and Other long-term liabilities on our accompanying unaudited condensed consolidated balance sheets. Our deferred revenue balance was $378 million as of September 30, 2018 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. We recognized revenue of $27 million in the third quarter of 2018 and $80 million in the first nine months of2018 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 reasonably estimate the expected rebates, we record a liability for the maximum rebate percentage offered. We have entered certain agreements with group purchasing organizations 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 unaudited condensed consolidated financial statements.

New Accounting Pronouncements and Changes in Accounting Principles [Abstract]

Description of New Accounting Pronouncements Not yet Adopted [Text Block]

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 liabilities on the balance sheet, including those previously classified as operating leases under current U.S. GAAP, and disclosing key information about leasing arrangements. Topic 842, as amended, is effective for annual periods beginning after December 15, 2018, including interim periods within those annual periods, with early adoption permitted.

We currently plan to adopt the standard using the transition method provided by ASC Update No. 2018-11, Leases (Topic 842): Targeted Improvements. Under this method, we plan to initially apply the new leasing rules on January 1, 2019, and recognize the cumulative effect of initially applying the standard as an adjustment to our opening balance of retained earnings, rather than at the earliest comparative period presented in the financial statements.

We have reached conclusions on several policy elections available under Topic 842 that we plan to apply on January 1, 2019. Upon transition, we will apply the package of practical expedients and will not reassess whether any expired or existing contracts are or contain leases, the classification of any expired or existing leases, and initial direct costs for any existing leases. We will apply the transition package of practical expedients described above to our entire lease portfolio at January 1, 2019. Furthermore, we have elected not to separate lease and non-lease components for the majority of our leases. Instead, for these applicable classes of underlying assets, we will account for each separate lease component, and the non-lease components associated with that lease component, as a single lease component.

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 on January 1, 2019. 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.

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.

ASC Update No. 2018-09

In July 2018, the FASB issued ASC Update No. 2018-09, Codification Improvements. The purpose of Update No. 2018-09 is to clarify, correct errors in or make minor improvements to the Codification. The amendments make the Codification easier to understand and apply by eliminating inconsistencies and providing clarifications. The transition and effective date guidance is based on the facts and circumstances of each amendment. Some of the amendments in Update No. 2018-09 do not require transition guidance and are effective upon issuance. However, many of the amendments in Update No. 2018-09 do have transition guidance with an effective date of 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.

ASC Update No. 2018-15

In August 2018, the FASB issued ASC Update No. 2018-15, Intangibles – Goodwill and Other – Internal-Use Software (Subtopic 350-40): Customer’s Accounting for Implementation Costs Incurred in a Cloud Computing Arrangement That Is a Service Contract. The purpose of Update No. 2018-15 is to align the requirements for capitalizing implementation costs incurred in a hosting arrangement that is a service contract with the requirements for capitalizing implementation costs incurred to develop or obtain internal-use software (and hosting arrangements that include an internal-use software license). Update No. 2018-15 is effective for annual periods beginning after December 15, 2019, including interim periods within those annual periods. Early adoption is permitted, including adoption in any interim period. 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, in the period had or are expected to have a material impact on our unaudited condensed consolidated financial statements.

In May 2014, the FASB issued FASB ASC Topic 606, 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 retained earnings of $177 million on January 1, 2018, primarily related to the cost of providing non-contractual post-implant support to certain customers, which we historically 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 resulted in an increase in Other current liabilities of $59 million and an increase in Other long-term liabilities of $205 million as of September 30, 2018, 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 $41 million as of September 30, 2018. The remaining impact of adopting FASB ASC Topic 606 was not material to our financial position or results of operations.

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 (loss) were reclassified to retained earnings,and all future fair value changes will be recorded to Net income (loss). For privately-held securities, we elected the measurement alternative approach for our existing investments, 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 (benefit).

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.

Fair Value Measurements Hedging Activities and Fair Value Measurements (Policies)

Fair Value Disclosures [Abstract]

Fair Value Measurement, Policy [Policy Text Block]

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

Derivatives, Policy [Policy Text Block]

Our derivative instruments do not subject our earnings to material risk, as the gains or losses on these derivatives generally offset losses or gains recognized on the hedged item.

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.

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.

ASC Update No. 2016-02, Leases (Topic 842) [Policy Text Block]

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 liabilities on the balance sheet, including those previously classified as operating leases under current U.S. GAAP, and disclosing key information about leasing arrangements. Topic 842, as amended, is effective for annual periods beginning after December 15, 2018, including interim periods within those annual periods, with early adoption permitted.

We currently plan to adopt the standard using the transition method provided by ASC Update No. 2018-11, Leases (Topic 842): Targeted Improvements. Under this method, we plan to initially apply the new leasing rules on January 1, 2019, and recognize the cumulative effect of initially applying the standard as an adjustment to our opening balance of retained earnings, rather than at the earliest comparative period presented in the financial statements.

We have reached conclusions on several policy elections available under Topic 842 that we plan to apply on January 1, 2019. Upon transition, we will apply the package of practical expedients and will not reassess whether any expired or existing contracts are or contain leases, the classification of any expired or existing leases, and initial direct costs for any existing leases. We will apply the transition package of practical expedients described above to our entire lease portfolio at January 1, 2019. Furthermore, we have elected not to separate lease and non-lease components for the majority of our leases. Instead, for these applicable classes of underlying assets, we will account for each separate lease component, and the non-lease components associated with that lease component, as a single lease component.

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 on January 1, 2019. 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.

ASC Update No. 2016-13 [Policy Text Block]

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.

ASC Update No. 2018-09

In July 2018, the FASB issued ASC Update No. 2018-09, Codification Improvements. The purpose of Update No. 2018-09 is to clarify, correct errors in or make minor improvements to the Codification. The amendments make the Codification easier to understand and apply by eliminating inconsistencies and providing clarifications. The transition and effective date guidance is based on the facts and circumstances of each amendment. Some of the amendments in Update No. 2018-09 do not require transition guidance and are effective upon issuance. However, many of the amendments in Update No. 2018-09 do have transition guidance with an effective date of annual periods beginning after December 15, 2018.
