AMGEN INC.
NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS
March 31,September 30, 2019
(Unaudited)
1. Summary of significant accounting policies
Business
Amgen Inc. (including its subsidiaries, referred to as “Amgen,” “the Company,” “we,” “our” or “us”) is a global biotechnology pioneer that discovers, develops, manufactures and delivers innovative human therapeutics. We operate in one1 business segment: human therapeutics.
Basis of presentation
The financial information for the three and nine months ended March 31,September 30, 2019 and 2018, is unaudited but includes all adjustments (consisting of only normal, recurring adjustments unless otherwise indicated), which Amgen considers necessary for a fair presentation of its condensed consolidated results of operations for those periods. Interim results are not necessarily indicative of results for the full fiscal year.
The condensed consolidated financial statements should be read in conjunction with our consolidated financial statements and the notes thereto contained in our Annual Report on Form 10-K for the year ended December 31, 2018.2018, and with our condensed consolidated financial statements and the notes thereto contained in our Quarterly Reports on Form 10-Q for the periods ended March 31, 2019 and June 30, 2019.
Principles of consolidation
The condensed consolidated financial statements include the accounts of Amgen as well as its majority-owned subsidiaries. We do not have any significant interests in anyvariable interest entities. All material intercompany transactions and balances have been eliminated in consolidation.
Use of estimates
The preparation of condensed consolidated financial statements in conformity with U.S. generally accepted accounting principles (GAAP) requires management to make estimates and assumptions that affect the amounts reported in the condensed consolidated financial statements and accompanying notes. Actual results may differ from those estimates.
Property, plant and equipment, net
Property, plant and equipment is recorded at historical cost, net of accumulated depreciation and amortization of $7.9$8.2 billion and $7.8 billion as of March 31,September 30, 2019 and December 31, 2018, respectively.
Leases
Adoption of new lease standard
In February 2016, the Financial Accounting Standards Board (FASB) issued a new accounting standard that amends the guidance for the accounting and disclosure of leases. This new standard requires that lessees recognize the assets and liabilities that arise from leases on the balance sheet, including leases classified as operating leases, and that they disclose qualitative and quantitative information about leasing arrangements. The FASB subsequently issued additional amendments to address issues arising from the implementation of the new lease standard. We adopted this standard as of January 1, 2019, using the modified-retrospective method. This approach provides a method for recording existing leases at adoption. We used the adoption date as our date of initial application, and thus, comparative-period financial information is not presented for periods prior to the adoption date. In addition, we elected the package of practical expedients permitted under the transition guidance within the new standard, which, among other things, allowed us to carry forward the historical lease classification.
Adoption of the new standard resulted in total lease liabilities of $510 million and right-of-use (ROU) assets of $439 million as of January 1, 2019. The difference between the initial lease liabilities and the ROU assets is related primarily to previously existing lease liabilities. The standard did not materially impact our Condensed Consolidated Statements of Income and had no impact on our Condensed Consolidated Statements of Cash Flows. Our accounting policies under the new standard are described below. See Note 8,9, Leases.

Lease recognition
At inception of a contract, we determine whether an arrangement is or contains a lease. For all leases, we determine the classification as either operating or financing. Operating leases are included in Other assets, Accrued liabilities and Other noncurrent liabilities in our Condensed Consolidated Balance Sheets.

ROU assets represent our right to use an underlying asset for the lease term, and lease liabilities represent our obligation to make lease payments under the lease. Lease recognition occurs at the commencement date, and lease liability amounts are based on the present value of lease payments overmade during the lease term. Our lease terms may include options to extend or terminate the lease when it is reasonably certain that we will exercise that option. Because most of our leases do not provide information to determine an implicit interest rate, we use our incremental borrowing rate in determining the present value of lease payments. ROU assets also include any lease payments made prior to the commencement date and exclude lease incentives received. Operating lease expense is recognized on a straight-line basis over the lease term.
We have lease agreements with both lease and nonlease components, which are generally accounted for together as a single lease component. In addition, for certain vehicle and equipment leases, we apply a portfolio approach to determine the lease term and discount rate.
Other recent accounting pronouncements
In June 2016, the FASB issued a new accounting standard that amends the guidance for measuring and recording credit losses on financial assets measured at amortized cost by replacing the incurred-loss model with an expected-loss model. Accordingly, these financial assets will be presented at the net amount expected to be collected. This new standard also requires that credit losses related to available-for-sale debt securities be recorded as an allowance through net income rather than by reducing the carrying amount under the current, other-than-temporary-impairment model. The new standard is effective for interim and annual periods beginning on January 1, 2020, but may be adopted earlier.2020. With certain exceptions, adjustments are to be applied using a modified-retrospective approach by reflecting adjustments through a cumulative-effect impact on retained earnings as of the beginning of the fiscal year of adoption. We arehave substantially completed our impact assessment and do not currently evaluating theanticipate a material impact that this new standard will have on our condensed consolidated financial statements.
2. Business combinations
Nuevolution AB
On July 15, 2019, we acquired all of the outstanding stock of Nuevolution AB (Nuevolution), a publicly traded, Denmark-based biotechnology company with a leading small-molecule-drug discovery platform, for total consideration of $183 million in cash. The transaction, which was accounted for as a business combination, expands our ability to discover novel small molecules against difficult-to-drug targets and with greater speed and efficiency. Nuevolution’s operations, which are not material, have been included in our condensed consolidated financial statements commencing on the acquisition date.
We allocated the consideration to acquire Nuevolution to finite-lived intangible assets of $150 million, comprised primarily of technology rights for a drug discovery platform with an estimated useful life of 10 years; goodwill of $26 million, which is not tax deductible; deferred tax liabilities of $22 million; and other net assets of $29 million.
The estimated fair values of intangible assets were determined primarily using a probability-weighted income approach, which discounts expected future cash flows to present value by using a discount rate that represents the estimated rate that market participants would use to value the intangible assets.
Our accounting for this acquisition is preliminary and will be finalized upon completion of our analysis to determine the acquisition date fair values of certain assets acquired, tax-related items and the residual impact on goodwill.
Otezla®
On August 25, 2019, we entered into an agreement with Celgene Corporation (Celgene) in connection with Celgene’s previously announced merger with Bristol-Myers Squibb Company (BMS) to acquire worldwide rights to Otezla® (apremilast), the only oral, nonbiologic treatment for psoriasis and psoriatic arthritis, and certain related assets and liabilities for $13.4 billion. We expect to fund the purchase price with cash. The transaction is expected to close by the end of 2019.

Hedging gains and losses, which are included in product sales, were not material for the three and nine months ended March 31,September 30, 2019 and 2018.

3.
4. Income taxes
Effective tax rates for the three and nine months ended September 30, 2019, were 13.6% and 14.2%, respectively, compared with 11.2% and 12.1%, respectively, for the corresponding periods of the prior year.
The increases in our effective tax rates for the three and nine months ended March 31,September 30, 2019, and 2018, were 13.9% and 11.8%, respectively.
The increase in our effective tax rate for the three months ended March 31, 2019, was due primarily to a prior-year tax benefit associated with intercompany sales under U.S. corporate tax reform. The effective tax rates differ from the federal statutory rate primarily as a result of foreign earnings from the Company’s operations conducted in Puerto Rico, a territory of the United States that is treated as a foreign jurisdiction for U.S. tax purposes and that is subject to tax incentive grants through 2035; these earnings are subject to U.S. tax at a reduced rate of 10.5% rate..
The U.S. territory of Puerto Rico imposes an excise tax on the gross intercompany purchase price of goods and services from our manufacturer in Puerto Rico. The rate of 4% is effective through December 31, 2027. We account for the excise tax as a manufacturing cost that is capitalized in inventory and expensed in cost of sales when the related products are sold. For U.S. income tax purposes, the excise tax results in foreign tax credits that are generally recognized in our provision for income taxes when the excise tax is incurred.
One or more of our legal entities file income tax returns in the U.S. federal jurisdiction, various U.S. state jurisdictions and certain foreign jurisdictions. Our income tax returns are routinely examined by the tax authorities in those jurisdictions. Significant disputes may arise with authorities involving issues of the timing and amount of deductions, the use of tax credits and allocations of income and expenses among various tax jurisdictions because of differing interpretations of tax laws, regulations and the interpretation of the relevant facts. As previously disclosed, we received a Revenue Agent Report (RAR) from the Internal Revenue Service (IRS) for the years 2010, 2011 and 2012. The RAR proposes to make significant adjustments that relate primarily to the allocation of profits between certain of our entities in the United States and the U.S. territory of Puerto Rico. In November 2017, we received a modified RAR that revised the IRS’s calculation but continued to propose substantial adjustments. We disagree with the proposed adjustments and are pursuing resolution with the IRS administrative appeals office, which currently has jurisdiction over the matter. If we deem necessary, we will vigorously contest the proposed adjustments through the judicial process. Final resolution of this complex matter is not likely within the next 12 months and could have a material impact on our condensed consolidated financial statements. We believe our accrual for income tax liabilities is appropriate based on past experience, interpretations of tax law and judgments about potential actions by tax authorities; however, due to the complexity of the provision for income taxes, the ultimate resolution of any tax matters may result in payments greater or less than amounts accrued. We are no longer subject to U.S. federal income tax examinations for years ended on or before December 31, 2009. In addition, we are currently under examination by a number of other state and foreign tax jurisdictions.
During the three and nine months ended March 31,September 30, 2019, the gross amounts of our unrecognized tax benefits (UTBs) increased $90$50 million and $160 million, respectively, as a result of tax positions taken during the current year. Substantially all of the UTBs as of March 31,September 30, 2019, if recognized, would affect our effective tax rate.

4.5. Earnings per share
The computation of basic earnings per share (EPS) is based on the weighted-average number of our common shares outstanding. The computation of diluted EPS is based on the weighted-average number of our common shares outstanding and dilutive potential common shares, which include primarily shares that may be issued under our stock option, restricted stock and performance unit award programs (collectively, dilutive securities), as determined by using the treasury stock method.

The computations for basic and diluted EPS were as follows (in millions, except per-share data):

For the three months ended March 31,September 30, 2019 and 2018, realized gains on interest-bearing securities were $1$21 million and $17$5 million, respectively, and realized losses on interest-bearing securities were $5$24 million and $151$108 million, respectively. For the nine months ended September 30, 2019 and 2018, realized gains on interest-bearing securities were $23 million and $27 million, respectively, and realized losses on interest-bearing securities were $32 million and $379 million, respectively. Realized gains and losses on interest-bearing securities are recorded in Interest and other income, net, in the Condensed Consolidated Statements of Income. The cost of securities sold is based on the specific-identification method. As of September 30, 2019, we had $1.1 billion in receivables related to sales of securities, which were recorded in Other current assets in the Condensed Consolidated Balance Sheets.

The primary objective of our investment portfolio is to enhance overall returns in an efficient manner while maintaining safety of principal, prudent levels of liquidity and acceptable levels of risk. Our investment policy limits interest-bearing security investments to certain types of debt and money market instruments issued by institutions with primarily investment-grade credit ratings, and it places restrictions on maturities and concentration by asset class and issuer.
We review our available-for-sale investments for other-than-temporary declines in fair value below our cost basis each quarter and whenever events or changes in circumstances indicate that the cost basis of an asset may not be recoverable. The evaluation is based on a number of factors, including the length of time and the extent to which the fair value has been below our cost basis as well as adverse conditions related specifically to the security, such as any changes to the credit rating of the security and the intent to sell or whether we will more likely than not be required to sell the security before recovery of its amortized cost basis. Our assessment of whether a security is other-than-temporarily impaired could change in the future based on new developments or changes in assumptions related to that particular security. As of March 31, 2019, unrealized losses on available-for-sale investments were due primarily to higher interest rates than at the time the securities were purchased. As of March 31,September 30, 2019 and December 31, 2018, we believe the cost bases for our available-for-sale investments were recoverable in all material respects.
Equity securities
We held investments in equity securities with readily determinable fair values of $246$277 million and $176 million as of March 31,September 30, 2019 and December 31, 2018, respectively, which are included in Other assets in the Condensed Consolidated Balance Sheets. Gains and losses recognized on equity securities with readily determinable fair values, including gains and losses recognized on sales, were not material for the three and nine months ended March 31,September 30, 2019 and 2018.

As of March 31,September 30, 2019 and December 31, 2018, respectively, we held investments of $185$170 million and $222 million in equity securities without readily determinable fair values, which are included in Other assets in the Condensed Consolidated Balance Sheets. Adjustments to the carrying values of these securities were not material for the three and nine months ended March 31,September 30, 2019 and 2018.

8.9. Leases
On January 1, 2019, we adopted a new accounting standard that amends the guidance for the accounting and reporting of leases. Certain required disclosures have been made on a prospective basis in accordance with the guidance of the standard. See Note 1, Summary of significant accounting policies.
We lease certain facilities and equipment related primarily to administrative, R&D and sales and marketing activities. Leases with lease terms of 12 months or less are expensed on a straight-line basis over the lease term and are not recorded in the Condensed Consolidated Balance Sheets.
Most leases include one or more options to renew, with renewal terms that canmay extend the lease term up to seven years. The exercise of lease renewal options is at our sole discretion. In addition, some of our lease agreements include rental payments adjusted periodically for inflation. Our lease agreements neither contain any residual value guarantees nor impose any significant restrictions or covenants. We sublease certain real estate to third parties. Our sublease portfolio consists of operating leases from former R&D and administrative space.

To estimate the fair value of our financial assets and liabilities, we use valuation approaches within a hierarchy that maximizes the use of observable inputs and minimizes the use of unobservable inputs by requiring that observable inputs be used when available. Observable inputs are inputs that market participants would use in pricing an asset or liability based on market data obtained from sources independent of the Company. Unobservable inputs are inputs that reflect the Company’s assumptions about the inputs that market participants would use in pricing an asset or liability and are developed based on the best information available in the circumstances. The fair value hierarchy is divided into three levels based on the source of inputs as follows:
Level 1Valuations based on unadjusted quoted prices in active markets for identical assets or liabilities that the Company has the ability to access
Level 2Valuations for which all significant inputs are observable either directly or indirectly—other than Level 1 inputs
Level 3Valuations based on inputs that are unobservable and significant to the overall fair value measurement
The availability of observable inputs can vary among the various types of financial assets and liabilities. To the extent that the valuation is based on models or inputs that are less observable or unobservable in the market, the determination of fair value requires more judgment. In certain cases, the inputs used for measuring fair value may fall into different levels of the fair value hierarchy. In such cases, for financial statement disclosure purposes, the level in the fair value hierarchy within which the fair value measurement is categorized is based on the lowest level of input used that is significant to the overall fair value measurement.

Interest-bearing and equity securities
The fair values of our U.S. Treasury securities, money market mutual funds and equity securities are based on quoted market prices in active markets, with no valuation adjustment.
Most of our other government-related and corporate debt securities are investment grade and have maturity dates offiveyears or less from the balance sheet date. Our other government-related debt securities portfolio is composed of securities with weighted-average credit ratings of A–BBB+ or equivalent by Standard & Poor’s Financial Services LLC (S&P), Moody’s Investors Service, Inc. (Moody’s), or Fitch Ratings, Inc. (Fitch); and our corporate debt securities portfolio has weighted-average credit ratings of A– or equivalent by Fitch and BBB+S&P, Moody’s or equivalent by S&P or Moody’s.Fitch. We estimate the fair values of these securities by taking into consideration valuations obtained from third-party pricing services. The pricing services use industry-standard valuation models, including both income- and market-based approaches, for which all significant inputs are observable either directly or indirectly to estimate fair value. The inputs include reported trades of and broker-dealer quotes on the same or similar securities; issuer credit spreads; benchmark securities; and other observable inputs.
Our residential-mortgage-, other-mortgage- and asset-backed-securities portfolio is composed entirely of senior tranches with credit ratings of AAA by S&P, Moody’s or Fitch. We estimate the fair values of these securities by taking into consideration valuations obtained from third-party pricing services. The pricing services use industry-standard valuation models, including both income- and market-based approaches, for which all significant inputs are observable either directly or indirectly to estimate fair value. The inputs include reported trades of and broker-dealer quotes on the same or similar securities; issuer credit spreads; benchmark securities; prepayment or default projections based on historical data; and other observable inputs.
We value our other short-term interest-bearing securities at amortized cost, which approximates fair value given their near-term maturity dates.

Derivatives
All of our foreign currency forward and option derivative contracts have maturities of three years or less, and all are with counterparties that have minimum credit ratings of A– or equivalent by S&P, Moody’s or Fitch. We estimate the fair values of these contracts by taking into consideration valuations obtained from a third-party valuation service that uses an income-based industry-standard valuation model for which all significant inputs are observable either directly or indirectly. These inputs include foreign currency exchange rates, the London Interbank Offered Rate (LIBOR), swap rates and obligor credit default swap rates. In addition, inputs for our foreign currency option contracts include implied volatility measures. These inputs, when applicable, are at commonly quoted intervals. See Note 12,13, Derivative instruments.
Our cross-currency swap contracts are with counterparties that have minimum credit ratings of A– or equivalent by S&P, Moody’s or Fitch. We estimate the fair values of these contracts by taking into consideration valuations obtained from a third-party valuation service that uses an income-based industry-standard valuation model for which all significant inputs are observable either directly or indirectly. These inputs include foreign currency exchange rates, LIBOR, swap rates, obligor credit default swap rates and cross-currency-basis swap spreads. See Note 12,13, Derivative instruments.
Our interest rate swap contracts are with counterparties that have minimum credit ratings of A– or equivalent by S&P, Moody’s or Fitch. We estimate the fair values of these contracts by using an income-based industry-standard valuation model for which all significant inputs are observable either directly or indirectly. These inputs include LIBOR, swap rates and obligor credit default swap rates. See Note 12,13, Derivative instruments.
Contingent consideration obligations
As a result of our business acquisitions,combinations, we have incurred contingent consideration obligations. The contingent consideration obligations are recorded at their fair values by using probability-adjusted discounted cash flows, and we revalue these obligations each reporting period until the related contingencies have been resolved. The fair value measurements of these obligations are based on significant unobservable inputs related to licensing rights and product candidates acquired in business combinations, and they are reviewed quarterly by management in our R&D and commercial sales organizations. These inputs include, as applicable, estimated probabilities and the timing of achieving specified regulatory and commercial milestones as well as estimated annual sales. Significant changes that increase or decrease the probabilities of achieving the related regulatory and commercial events or that shorten or lengthen the time required to achieve such events or that increase or decrease estimated annual sales would result in corresponding increases or decreases in the fair values of the obligations, as applicable. Changes in the fair values of contingent consideration obligations are recognized in Other operating expenses in the Condensed Consolidated Statements of Income. Changes in the carrying amounts of contingent consideration obligations for the three and nine months ended March 31,September 30, 2019 and 2018, were not material.
During the three and nine months ended March 31,September 30, 2019 and 2018, there were no transfers of assets or liabilities between fair value measurement levels, and there were no material remeasurements to the fair values of assets and liabilities that are not measured at fair value on a recurring basis.basis, except with respect to the 2018 discontinuance of the internal development of a nonkey program resulting in an impairment of an IPR&D asset of $330 million, which was recognized in Other operating expenses in the Condensed Consolidated Statements of Income and included in Other items, net, in the Condensed Consolidated Statements of Cash Flows.
Summary of the fair values of other financial instruments
Cash equivalents
The fair values of cash equivalents approximate their carrying values due to the short-term nature of such financial instruments.
Borrowings
We estimated the fair values of our borrowings by using Level 2 inputs. As of March 31,September 30, 2019 and December 31, 2018, the aggregate fair values of our borrowings were $34.8$33.3 billion and $35.0 billion, respectively, and the carrying values were $33.0$29.8 billion and $33.9 billion, respectively.

13. Derivative instruments
The Company is exposed to foreign currency exchange rate and interest rate risks related to its business operations. To reduce our risks related to such exposures, we use or have used certain derivative instruments, including foreign currency forward, foreign currency option, cross-currency swap, forward interest rate and interest rate swap contracts. We do not use derivatives for speculative trading purposes.
Cash flow hedges
We are exposed to possible changes in the values of certain anticipated foreign currency cash flows resulting from changes in foreign currency exchange rates associated primarily with our euro-denominated international product sales. Increases and decreases in the cash flows associated with our international product sales due to movements in foreign currency exchange rates are offset partially by corresponding increases and decreases in the cash flows from our international operating expenses resulting from these foreign currency exchange rate movements. To further reduce our exposure to foreign currency exchange rate fluctuations with regard to our international product sales, we enter into foreign currency forward and option contracts to hedge a portion of our projected international product sales primarily over a three-year time horizon, with, at any given point in time, a higher percentage of nearer-term projected product sales being hedged than in successive periods.
As of both March 31,September 30, 2019 and December 31, 2018, we had outstanding foreign currency forward contracts with aggregate notional amounts of $4.6 billion and $4.5 billion, andrespectively. As of December 31, 2018, we had outstanding foreign currency option contracts with an aggregate notional amountsamount of $21 million.million and no such outstanding contracts as of September 30, 2019. We have designated these foreign currency forward and foreign currency option contracts, which are primarily euro based, as cash flow hedges. Accordingly, we report the unrealized gains and losses on these contracts in AOCI in the Condensed Consolidated Balance Sheets, and we reclassify them to Product sales in the Condensed Consolidated Statements of Income in the same periods during which the hedged transactions affect earnings.
To hedge our exposure to foreign currency exchange rate risk associated with certain of our long-term debt denominated in foreign currencies, we enter into cross-currency swap contracts. Under the terms of such contracts, we paid euros, pounds sterling and Swiss francs and received U.S. dollars for the notional amounts at the inception of the contracts; and based on these notional amounts, we exchange interest payments at fixed rates over the lives of the contracts by paying U.S. dollars and receiving euros, pounds sterling and Swiss francs. In addition, we will pay U.S. dollars to and receive euros, pounds sterling and Swiss francs from the counterparties at the maturities of the contracts for these same notional amounts. The terms of these contracts correspond to the related hedged debt, thereby effectively converting the interest payments and principal repayment on the debt from euros, pounds sterling and Swiss francs to U.S. dollars. We have designated these cross-currency swap contracts as cash flow hedges. Accordingly, the unrealized gains and losses on these contracts are reported in AOCI in the Condensed Consolidated Balance Sheets and reclassified to Interest and other income, net, in the Condensed Consolidated Statements of Income in the same periods during which the hedged debt affects earnings.
The notional amounts and interest rates of our cross-currency swaps as of March 31,September 30, 2019, were as follows (notional amounts in millions):

During the three months ended September 30, 2019, our 2.125% 2019 euro Notes matured, and the related cross-currency swaps were settled.
In connection with the anticipated issuance of long-term fixed-rate debt, we occasionally enter into forward interest rate contracts in order to hedge the variability in cash flows due to changes in the applicable U.S. Treasury rate between the time we enter into these contracts and the time the related debt is issued. Gains and losses on forward interest rate contracts, which are designated as cash flow hedges, are recognized in AOCI in the Condensed Consolidated Balance Sheets and are amortized into Interest expense, net, in the Condensed Consolidated Statements of Income over the lives of the associated debt issuances. Amounts recognized in connection with forward interest rate swaps during the threenine months ended March 31,September 30, 2019, and amounts expected to be recognized during the subsequent 12 months are not material.

No portions of our cash flow hedge contracts were excluded from the assessment of hedge effectiveness. As of March 31, 2019, we expected to reclassify $83 million of net losses on our foreign currency and cross-currency swap contracts out of AOCI and into earnings during the next 12 months.
Fair value hedges
To achieve a desired mix of fixed-rate and floating-rate debt, we entered into interest rate swap contracts that qualified for and were designated as fair value hedges. These interest rate swap contracts effectively convert fixed-rate coupons to floating-rate LIBOR-based coupons over the terms of the related hedge contracts. As of March 31,September 30, 2019 and December 31, 2018, we had interest rate swap contracts with aggregate notional amounts of $9.55 billion and $10.95 billion, respectively, that hedge certain portions of our long-term debt issuances.
For interest rate swap contracts that qualify for and are designated as fair value hedges, we recognize in Interest expense, net, in the Condensed Consolidated Statements of Income the unrealized gain or loss on the derivative resulting from the change in fair value during the period, as well as the offsetting unrealized loss or gain of the hedged item resulting from the change in fair value during the period attributable to the hedged risk. If a hedging relationship involving an interest rate swap contract is terminated, the gain or loss realized on contract termination is recorded as an adjustment to the carrying value of the debt and amortized into Interest expense, net, over the remaining life of the previously hedged debt.

Our derivative contracts that were in liability positions as of March 31,September 30, 2019, contain certain credit-risk-related contingent provisions that would be triggered if (i) we were to undergo a change in control and (ii) our or the surviving entity’s creditworthiness deteriorates, which is generally defined as having either a credit rating that is below investment grade or a materially weaker creditworthiness after the change in control. If these events were to occur, the counterparties would have the right but not the obligation to close the contracts under early-termination provisions. In such circumstances, the counterparties could request immediate settlement of these contracts for amounts that approximate the then current fair values of the contracts. In addition, our derivative contracts are not subject to any type of master netting arrangement, and amounts due either to or from a counterparty under the contracts may be offset against other amounts due either to or from the same counterparty only if an event of default or termination, as defined, were to occur.
The cash flow effects of our derivative contracts in the Condensed Consolidated Statements of Cash Flows are included in Net cash provided by operating activities, except for the settlement of notional amounts of cross-currency swaps, which are included in the Condensed Consolidated Statements of Cash Flows.Net cash used in financing activities.

Contingencies
In the ordinary course of business, we are involved in various legal proceedings, government investigations and other matters that are complex in nature and have outcomes that are difficult to predict. See our Annual Report on Form 10-K for the year ended December 31, 2018, Part I, Item 1A. Risk Factors—Our business may be affected by litigation and government investigations. We describe our legal proceedings and other matters that are significant or that we believe could become significant in this footnote.footnote; in Note 20, Contingencies and commitments, to the consolidated financial statements in our Annual Report on Form 10-K for the year ended December 31, 2018; or in Note 13, Contingencies and commitments, to the condensed consolidated financial statements in our Quarterly Reports on Form 10-Q for the periods ended March 31, 2019 and June 30, 2019.
We record accruals for loss contingencies to the extent that we conclude it is probable that a liability has been incurred and the amount of the related loss can be reasonably estimated. We evaluate, on a quarterly basis, developments in legal proceedings and other matters that could cause an increase or decrease in the amount of the liability that has been accrued previously.
Our legal proceedings involve various aspects of our business and a variety of claims, some of which present novel factual allegations and/or unique legal theories. In each of the matters described in this filing orfiling; in Note 20, Contingencies and commitments, to the consolidated financial statements in our Annual Report on Form 10-K for the year ended December 31, 2018,2018; or in Note 13, Contingencies and commitments, to the condensed consolidated financial statements in our Quarterly Reports on Form 10-Q for the periods ended March 31, 2019 and June 30, 2019, in which we could incur a liability, our opponents seek an award of a not-yet-quantified amount of damages or an amount that is not material. In addition, a number of the matters pending against us are at very early stages of the legal process, which, in complex proceedings of the sort we face often extend for several years. As a result, none of the matters described in this filing orfiling; in Note 20, Contingencies and commitments, to the consolidated financial statements in our Annual Report on Form 10-K for the year ended December 31, 2018,2018; or in Note 13, Contingencies and commitments, to the condensed consolidated financial statements in our Quarterly Reports on Form 10-Q for the periods ended March 31, 2019 and June 30, 2019, in which we could incur a liability, have progressed sufficiently through discovery and/or the development of important factual information and legal issues to enable us to estimate a range of possible loss, if any, or such amounts are not material. While it is not possible to accurately predict or determine the eventual outcomes of these matters, an adverse determination in one or more of these matters currently pending could have a material adverse effect on our consolidated results of operations, financial position or cash flows.
Certain recent developments concerning our legal proceedings and other matters are discussed below:

AbbVie Inc., et al. (April 25, 2019) (Construction Industry) (collectively, Humira® Antitrust Class Actions). In each of the Humira® Antitrust Class Actions, the plaintiffs bring federal antitrust claims along with various state law claims under state common law and state antitrust, consumer protection, and unfair competition statutes. In each case, the plaintiffs specifically allege that AbbVie has unlawfully monopolized the alleged market for Humira® and biosimilars of Humira®, including by creating an allegedly unlawful so-called patent thicket around Humira®. In the Local 1500, Sheet Metal Workers’ and Construction Industry cases, the plaintiffs further allege that AbbVie entered into allegedly unlawful market division agreements with Amgen and other companies that had developed Humira® biosimilars, including Samsung Bioepis Co., Ltd., Mylan Inc., Mylan Pharmaceuticals, Inc., Sandoz, Inc., Fresenius Kabi USA, LLC, Pfizer Inc. and Momenta Pharmaceuticals, Inc., in connection with the settlement of patent litigation relating to Humira®, whereby Amgen and the other defendants that have developed Humira® biosimilars were permitted to market those products in Europe as early as October 2018, while remaining off the market2019.
* Registered in the United States until 2023. In each of the Humira® Antitrust Class Actions other than the Local 1500 and Construction Industry cases, the plaintiffs allege that AbbVie and Amgen entered into an allegedly unlawful settlement agreement under which Amgen allegedly agreed to delay its entry into the U.S. market with AMGEVITATM, its Humira® biosimilar, in exchange for an alleged promise of exclusivity as the sole Humira® biosimilar in that market for five months, beginning in January 2023. In each of the Humira® Antitrust Class Actions, plaintiffs seek injunctive relief, treble damages and attorney’s fees on behalf of a putative class of third-party payers and/or consumers that have indirectly purchased, paid for or provided reimbursement for Humira® in the United States. Defendants’ responses to the first six complaints were stayed by the court and a status hearing is set for May 2, 2019.
U.S. Attorney’s Office for the District of Massachusetts-Patient Assistance Investigation
On April 25, 2019, Amgen, the U.S. Department of Justice and the Office of Inspector General (OIG) of the U.S. Department of Health and Human Services entered into a settlement agreement. Under that agreement, Amgen agreed to pay $24.75 million to resolve the government’s allegations relating to Amgen’s support of independent charitable organizations that provide patients with financial assistance to access their medicines. Additionally, Amgen and OIG entered into a Corporate Integrity Agreement that requires Amgen to maintain its corporate compliance program and to undertake a set of defined corporate integrity obligations for a period of five years.

In the following discussion of changes in product sales, any reference to unit demand growth or decline refers to changes in the purchases of our products by healthcare providers (such as physicians or their clinics), dialysis centers, hospitals and pharmacies. In addition, any reference to increases or decreases in inventory refers to changes in inventory held by wholesaler customers and end users (such as pharmacies).

Total product sales decreased for the three and nine months ended March 31,September 30, 2019, driven primarily by a decline in net selling price, and unfavorable changes in inventory, offset partially by higher unit demand. InFor the remainder of 2019, we continue to expect a lower net selling price compared with 2018.
Other revenues increaseddecreased for the three and nine months ended March 31,September 30, 2019, driven primarily by lower milestone payments, offset partially by higher royalties.
Operating expenses increaseddecreased for the three and nine months ended March 31,September 30, 2019 and 2018, driven primarily by higher Costthe favorable change resulting from an impairment charge associated with a nonkey IPR&D asset in the third quarter of sales and2018. The decrease in the nine months ended September 30, 2019, was offset partially by increased R&D expense.expenses.
Although changes in foreign currency exchange rates result in increases or decreases in our reported international product sales, the benefit or detriment that such movements have on our international product sales is offset partially by corresponding increases or decreases in our international operating expenses and our related foreign currency hedging activities. Our hedging activities seek to offset the impacts, both positive and negative, that foreign currency exchange rate changes may have on our net income by hedging our net foreign currency exposure, primarily with respect to product sales denominated in euros. The net impact from changes in foreign currency exchange rates was not material for the three and nine months ended March 31,September 30, 2019 and 2018.

The increase in ENBREL sales for the three months ended March 31,September 30, 2019, was driven primarily by an increase in net selling price and favorable impacts from changes in accounting estimates of sales deductions, offset partially by lower unit demand. The increase in ENBREL sales for the nine months ended September 30, 2019, was driven primarily by favorable impacts from changes in accounting estimates of sales deductions and product returns and a slightan increase in net selling price, offset partially by lower unit demand and unfavorable changes in inventory.
In 2019, we continue to expect lower unit demand compared with 2018.
In April 2019, the FDAU.S. Food and Drug Administration (FDA) approved a second biosimilar version of ENBREL. Other companies are also developing proposed biosimilar versions of ENBREL. Further,ENBREL, and we are involved in patent litigations with the two companies seeking to market their FDA-approved biosimilar versions of ENBREL.

The decreasedecreases in global Neulasta® sales for the three and nine months ended March 31,September 30, 2019, waswere driven primarily by lowerthe impact of biosimilar competition on net selling price and to a lesser extent, changes in inventory.unit demand. Neulasta® sales in 2019 included a $98 million order from the U.S. government.
Our final material U.S. patent for Neulasta® expired in October 2015. Therefore, we face increased competitiongovernment in the United States, which has had and will continue to have a material adverse impact on salesfirst quarter of Neulasta®. 2019.
Biosimilar versions of Neulasta® have been approved and launched, and other biosimilar versions may also receive approval in the near future. Therefore, we face increased competition in the United States and Europe, which has had and will continue to have a material adverse impact on sales of Neulasta®.

In addition, supplementary protection certificates issued by certain countries, including France, Germany, Italy, Spain and the United Kingdom, that are related to our European patent for Neulasta® expired in August 2017. In 2019, we expect European sales to decline with the launch of multiple long-acting biosimilar competitors.
Neulasta® sales have been and will continue to be affected by the development of new protocols, tests and/or treatments for cancer and/or new treatment alternatives, including those that have reduced and may continue to reduce the use of myelosuppressive regimens in some patients.

We are engaged in litigation with a number oftwo related companies that are challenging our material patents relatingrelated to KYPROLIS®and are seeking to market generic carfilzomib products, one of which has been tentatively approved by the FDA. See Note 13, Contingencies and commitments, to the condensed consolidated financial statements. These companies may seek to enter the U.S. market at risk as soon as their products are approved by the FDA, which could occur following the expiry of the stay of regulatory approval underproducts. Under the Hatch-Waxman Act, that currently preventsFDA approval of the FDAANDA at issue is stayed until at least January 20, 2020 (although the stay may be lifted in connection with a court order or in certain other instances permitted under the statute). Separately, we have entered into confidential settlement agreements with other companies developing generic carfilzomib products, and the court has entered consent judgments enjoining those companies from granting final approval before January 2020.

The decrease in EPOGEN® sales forinfringing certain of our patents, subject to terms of the three months ended March 31, 2019, was driven primarily by a decline in net selling price due to our contract with DaVita Inc. In 2019, we expect a lower net selling price compared with 2018.
Our final material U.S. patent for EPOGEN® expired in May 2015. We face competition in the United States, which has had and will continue to have a material adverse impact on sales of EPOGEN®. Multiple companies are developing proposed biosimilar versions of EPOGEN®. A biosimilar version of EPOGEN® was approved in the second quarter of 2018 and launched in the fourth quarter of 2018. Other biosimilar versions of EPOGEN® may also receive approval.

Our U.S. composition-of-matter patent related to Sensipar®, a small molecule, expired in March 2018. We are involved in litigation with a number of companies seeking to market generic cinacalcet products surrounding our U.S. formulation patent, thatwhich expires in September 2026. Separately, we have entered into confidential settlement agreements with other companies developing generic cinacalcet products, and the court has entered consent judgments enjoining those companies from infringing certain of our patents, subject to terms of the confidential settlement agreements. See Note 14, Contingencies and commitments, to the condensed consolidated financial statements in our Quarterly Report on Form 10-Q for the period ended September 30, 2019; Note 20, Contingencies and commitments, to the consolidated financial statements in our Annual Report on Form 10-K for the year ended December 31, 2018; and Note 13, Contingencies and commitments, to the condensed consolidated financial statements.statements in our Quarterly Reports on Form 10-Q for the periods ended March 31, 2019 and June 30, 2019. Certain manufacturers ofcompanies manufacturing generics began selling their generic cinacalcet products in the United States in late 2018 and early 2019, and some of this generic product remains commercially available in the United States from third-party distributors. We believe our product sales for Sensipar® sales have already been and we believe may continue to be adversely impacted as a result of generic productgeneric-product sales in the U.S. market.
In 2019, we expect Sensipar® sales will be lower than in 2018 due to existing and potential future generic-market entries, continued adoption of Parsabiv® and higher purchases in 2018 due to the reimbursement change from Medicare Part D to Part B.

Income taxes
The increaseincreases in our effective tax raterates for the three and nine months ended March 31,September 30, 2019, waswere due primarily to a prior-year tax benefit associated with intercompany sales under U.S. corporate tax reform.
As previously disclosed, we received aan RAR from the IRS for the years 2010, 2011 and 2012. The RAR proposes to make significant adjustments that relate primarily to the allocation of profits between certain of our entities in the United States and the U.S. territory of Puerto Rico. In November 2017, we received a modified RAR that revised the IRS’s calculation but continued to propose substantial adjustments. We disagree with the proposed adjustments and are pursuing resolution with the IRS administrative appeals office, which currently has jurisdiction over the matter. If we deem necessary, we will vigorously contest the proposed adjustments through the judicial process. Final resolution of this complex matter is not likely within the next 12 months and could have a material impact on our condensed consolidated financial statements. We believe our accrual for income tax liabilities is appropriate based on past experience, interpretations of tax law, and judgments about potential actions by tax authorities; however, due to the complexity of the provision for income taxes, the ultimate resolution of any tax matters may result in payments greater or less than amounts accrued.
See Note 3,4, Income taxes, to the condensed consolidated financial statements for further discussion.

Cash, cash equivalents and marketable securities
We have global access to our $26.3$20.9 billion balance of cash, cash equivalents and marketable securities asbecause we no longer reinvest the related undistributed foreign earnings indefinitely outside the United States. As a result of U.S. corporate tax reform in 2017, we recorded a repatriation tax liability on undistributed earnings generated from operations in foreign tax jurisdictions, which will be paid over eight years. The first two annual payments were made in April 2018 and April 2019, and the remaining scheduled payments total $6.2 billion. Further, the timing of settlement of the sales of certain of our securities reduced the balance of cash, cash equivalents and marketable securities as of September 30, 2019, as $1.1 billion of unsettled sales of securities were recorded in Other current assets in the Condensed Consolidated Balance Sheets. The change in composition of our portfolio to shorter duration investments during the third quarter of 2019 reflects our preparation to fund the cost of the anticipated acquisition of the worldwide rights to Otezla®(see Significant developments).
The primary objective of our investment portfolio is to enhance overall returns in an efficient manner while maintaining safety of principal, prudent levels of liquidity and acceptable levels of risk. Our investment policy limits interest-bearing security investments to certain types of debt and money market instruments issued by institutions with primarily investment-grade credit ratings, and it places restrictions on maturities and concentration by asset class and issuer.
Capital allocation
Consistent with the objective to optimize our capital structure, we seek to deploy our accumulated cash balances in an efficient manner, and we consider several alternatives such as payment of dividends, stock repurchases, repayment of debt and strategic transactions that expand our portfolio of products in areas of therapeutic interest.
We intend to continue to invest in our business while returning capital to stockholders through the payment of cash dividends and stock repurchases, thereby reflecting our confidence in the future cash flows of our business. The timing and amount of future dividends and stock repurchases will vary based on a number of factors, including future capital requirements for strategic transactions, availability of financing on acceptable terms, debt service requirements, our credit rating, changes to applicable tax laws or corporate laws, changes to our business model and periodic determination by our Board of Directors that cash dividends and/or

stock repurchases are in the best interests of stockholders and are in compliance with applicable laws and the Company’s agreements. In addition, the timing and amount of stock repurchases may also be affected by stock price and blackout periods, during which we are restricted from repurchasing stock. The manner of stock repurchases may include private block purchases, tender offers and market transactions.
In August 2019, March 2019 and December 2018, the Board of Directors declared a quarterly cash dividenddividends of $1.45 per share of common stock, which were paid on September 6, 2019, June 7, 2019 and March 8, 2019, respectively, an increase of 10% fromover the quarterly cash dividend paid in each quarter of the previous four quarters, which was paid on March 8, 2019.2018. In MarchOctober 2019, the Board of Directors declared a quarterly cash dividend of $1.45 per share of common stock, which will be paid on June 7,December 6, 2019.
We have also returned capital to stockholders through our stock repurchase program. During the threenine months ended March 31,September 30, 2019, we repurchased $3.0$6.6 billion of common stock. In May 2019, our Board of Directors increased the amount authorized under our stock repurchase program by an additional $5.0 billion. As of March 31,September 30, 2019, $2.1$3.6 billion of authorityauthorization remained available under our stock repurchase program.
As a result of stock repurchases and quarterly dividend payments, we have an accumulated deficit as of March 31,September 30, 2019 and December 31, 2018. Our accumulated deficit is not expected to affect our future ability to operate, repurchase stock, pay dividends or repay our debt given our continuing profitability and strong financial position.

We believe that existing funds, cash generated from operations and existing sources of and access to financing are adequate to satisfy our needs for working capital; capital expenditure and debt service requirements; our plans to pay dividends and repurchase stock; and other business initiatives we plan to strategically pursue, including acquisitions and licensing activities. We anticipate that our liquidity needs can be met through a variety of sources, including cash provided by operating activities, sales of marketable securities, borrowings through commercial paper and/or syndicated credit facilities and access to other domestic and foreign debt markets and equity markets. See our Annual Report on Form 10-K for the year ended December 31, 2018, Part I, Item 1A. Risk Factors—Global economic conditions may negatively affect us and may magnify certain risks that affect our business.
Certain of our financing arrangements contain nonfinancial covenants. In addition, our revolving credit agreement includes a financial covenant, which requires that we maintain a specified minimum interest coverage ratio of (i) the sum of consolidated net income, interest expense, provision for income taxes, depreciation expense, amortization expense, unusual or nonrecurring charges and other noncash items (Consolidated EBITDA) to (ii) Consolidated Interest Expense, each as defined and described in the credit agreement. We were in compliance with all applicable covenants under these arrangements as of March 31,September 30, 2019.

Operating
Cash provided by operating activities has been and is expected to continue to be our primary recurring source of funds. Cash provided by operating activities during the threenine months ended March 31,September 30, 2019, decreased compared with the same period in the prior year due primarily to an increase inlower Net income, adjusted for noncash items, timing of payments to corporate partners and sales deductions paid to customers and lower net income.customers.
Investing
Cash provided by investing activities during the threenine months ended March 31,September 30, 2019 and 2018, was due primarily to net cash inflows related to marketable securities of $3.7$12.4 billion and $14.9$19.3 billion, respectively. Higher cash inflows in the prior year reflectsreflect the cash to fund a $10.0 billion tender offer completed in 2018 to repurchase our common stock. Capital expenditures which were associated primarily with site development costs, including our Thousand Oaks, California, campus, as well as the next-generation biomanufacturing facility in Rhode Island and life cycle investments across the manufacturing network during the threenine months ended March 31,September 30, 2019 and 2018, were $116$430 million and $155$513 million, respectively. We currently estimate 2019 spending on capital projects to be approximately $700$650 million.

Financing
Cash used in financing activities during the threenine months ended March 31,September 30, 2019, was due primarily to repurchases of our common stock of $3.0$6.6 billion, repayment of debt of $1.0$4.5 billion and the payment of dividends of $0.9$2.6 billion. Cash used in financing activities during the threenine months ended March 31,September 30, 2018, was due primarily to repurchases of our common stock of $10.7$15.7 billion, repayment of debt of $500 million and the payment of dividends of $1.0$2.7 billion. See Note 9,10, Financing arrangements, and Note 10,11, Stockholders’ equity, to the condensed consolidated financial statements for further discussion.

Critical accounting policies
The preparation of our condensed consolidated financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the amounts reported in the financial statements and the notes to the financial statements. Some of those judgments can be subjective and complex, and therefore, actual results could differ materially from those estimates under different assumptions or conditions.

Item 4.CONTROLS AND PROCEDURES
We maintain “disclosure controls and procedures,” as such term is defined under the Securities Exchange Act Rule 13a-15(e), that are designed to ensure that information required to be disclosed in Amgen’s Exchange Act reports is recorded, processed, summarized and reported within the time periods specified in the SEC’s rules and forms, and that such information is accumulated and communicated to Amgen’s management, including its Chief Executive Officer and Chief Financial Officer, as appropriate, to allow timely decisions regarding required disclosures. In designing and evaluating the disclosure controls and procedures, Amgen’s management recognized that any controls and procedures, no matter how well designed and operated, can provide only reasonable assurance of achieving the desired control objectives and, in reaching a reasonable level of assurance, Amgen’s management necessarily was required to apply its judgment in evaluating the cost-benefit relationship of possible controls and procedures. We have carried out an evaluation under the supervision and with the participation of our management, including Amgen’s Chief Executive Officer and Chief Financial Officer, of the effectiveness of the design and operation of Amgen’s disclosure controls and procedures. Based upon their evaluation and subject to the foregoing, the Chief Executive Officer and Chief Financial Officer concluded that our disclosure controls and procedures were effective as of March 31,September 30, 2019.
Management determined that, as of March 31,September 30, 2019, there were no changes in our internal control over financial reporting that occurred during the fiscal quarter then ended that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

Item 1A.RISK FACTORS
This report and other documents we file with the SEC contain forward-looking statements that are based on current expectations, estimates, forecasts and projections about us, our future performance, our business, our beliefs and our management’s assumptions. These statements are not guarantees of future performance and involve certain risks, uncertainties and assumptions that are difficult to predict. You should carefully consider the risks and uncertainties our business faces. We haveThe risks described in our Annual Report on Form 10-K for the year ended December 31, 2018, the primary risks related to our business, and we periodically update those risks for material developments. Those risksbelow are not the only ones we face. Our business is also subject to the risks that affect many other companies, such as employment relations, general economic conditions, geopolitical events and international operations. Further, additional risks not currently known to us or that we currently believe are immaterial may in the future materially and adversely affect our business, operations, liquidity and stock price.
ThereOur sales depend on coverage and reimbursement from third-party payers, and pricing and reimbursement pressures may affect our profitability.
Sales of our products depend on the availability and extent of coverage and reimbursement from third-party payers, including government healthcare programs and private insurance plans. Governments and private payers continue to pursue initiatives to contain costs and manage drug utilization. These payers are noincreasingly focused on the effectiveness, benefits and costs of similar treatments, which could result for our products in lower reimbursement rates or narrower populations for whom payers will reimburse. Continued intense public scrutiny of the price of drugs and other healthcare costs, together with payer dynamics, may limit our ability to set or adjust the price of our products based on their value, which could have a material updatesadverse effect on our business. In the United States, the public discussions of drug pricing issues are likely to continue.
—Changing federal coverage and reimbursement policies and practices have impacted and may continue to impact access to and sales of our products
A substantial portion of our U.S. business relies on reimbursement from U.S. federal government healthcare programs and commercial insurance plans regulated by the risk factors previously disclosed in Part I, Item 1A, ofU.S. federal and state governments. See our Annual Report on Form 10-K for the year ended December 31, 2018.2018, Part I, Item 1. Business—Reimbursement. Our business has and will continue to be impacted by legislative actions changing U.S. federal reimbursement policy. For example, in February 2018, the U.S. Congress passed legislation requiring biopharmaceutical manufacturers to provide greater discounts beginning in 2019 on products dispensed to patients in the coverage gap between the initial coverage limit of Medicare Part D and the program’s catastrophic-coverage threshold, which has and will continue to reduce our net product sales relating to such patients. Additional legislative proposals have been introduced by members of Congress to overhaul provisions of the Patient Protection and Affordable Care Act to allow commercial-level reimportation of prescription medications from Canada or other countries and to enable Medicare to negotiate drug prices with biopharmaceutical manufacturers. Congressional focus on drug pricing has increased since the U.S. House of Representatives changed party control following the November 2018 election, and our industry is currently under greater scrutiny by Congress. For example, in January 2019, the chair of the House Oversight and Reform Committee sent letters to twelve different biopharmaceutical manufacturers, including Amgen, seeking documents and detailed information about such companies’ drug pricing practices. A number of other Congressional committees have also held hearings and evaluated proposed legislation on drug pricing. For example, in July 2019, the bipartisan Senate Finance Committee advanced a bill that would, among other things, penalize pharmaceutical manufacturers for raising prices on drugs covered by Medicare Parts B and D faster than the rate of inflation, cap out-of-pocket expenses for Medicare Part D beneficiaries, and make a number of changes to how drugs are reimbursed in Medicare Part B. In September 2019, a new drug pricing bill, H.R. 3, was introduced in the House, which, if enacted, enables direct price negotiations by the federal government on certain drugs (with the maximum price paid by Medicare capped based on an international index) and requires manufacturers to offer these negotiated prices to other payers, and restricts manufacturers from raising prices on drugs covered by Medicare Parts B and D. We expect continued significant focus on health care and drug pricing legislation through the November 2020 U.S. presidential election and beyond.

Also, our business has been and is expected to continue to be impacted by changes in U.S. federal reimbursement policy resulting from executive actions, federal regulations, or federal demonstration projects. For example, the U.S. presidential administration’s (the Administration) drug pricing “blueprint” released in May 2018 contains an array of policy ideas intended to increase competition, improve the negotiating power of the federal government, reduce drug prices and lower patient out-of-pocket costs with the potential to significantly impact, whether individually or collectively, the biopharmaceutical industry. Such policy ideas include moving coverage and reimbursement for Medicare Part B drugs into Medicare Part D, instituting a competitive acquisition program for Part B drugs in which competing third-party vendors take on the financial risk of acquiring drugs and billing Medicare, removing the safe harbor protection under the federal anti-kickback statute for drug rebates paid to payers, and requiring the inclusion of drug price information in direct-to-consumer drug advertising.
Since the release of this blueprint, the president and/or federal agencies, including the Centers for Medicare & Medicaid Services (CMS), have announced a number of demonstration projects, recommendations and proposals to implement various elements of the drug pricing blueprint. CMS is the federal agency responsible for administering Medicare and overseeing state Medicaid programs and Health Insurance Marketplaces, and has substantial power to implement policy changes or demonstration projects that can quickly and significantly affect how drugs, including our products, are covered and reimbursed. For example, in late 2018, CMS began evaluating a pilot program referred to as the “International Price Index (IPI)” model to, among other things, initially cover fifty percent of Medicare Part B single source drugs at payment amounts more closely aligned with international drug prices, and in June 2019, Administration officials announced that the Office of Management and Budget is reviewing a draft of a proposed rule to implement the IPI model. CMS has also issued guidance to allow certain Medicare plans offered by private insurance companies to require that patients receiving Medicare Part B drugs first try a drug preferred by the plan before covering another therapy (Step Therapy) and proposing lower reimbursement rates for new Part B drugs.
Separate from the drug pricing blueprint, CMS has undertaken other demonstration projects to test care models, such as the CMS Oncology Care Model, which provides participating physician practices with performance-based financial incentives that aim to manage or reduce Medicare costs without negatively impacting the efficacy of care. We believe the Oncology Care Model has reduced utilization of certain of our oncology products by participating physician practices and expect it to continue to do so in the future. And in July 2019, CMS released a proposed rule creating a new mandatory payment model focused on encouraging greater use of home dialysis and kidney transplants for end-stage renal disease patients that, if finalized as proposed, could result in changes to treatment of such patients, including reduction of the use of our erythropoiesis-stimulating agents and calcimimetic products. CMS has also solicited suggestions regarding other potential care models.
In this dynamic environment, we are unable to predict which or how many of these various federal policy, legislative or regulatory changes may ultimately be enacted. However, to the extent that these or other federal government initiatives decrease or modify the coverage or reimbursement available for our products, limit our ability to offer co-pay payment assistance to commercial patients, require that we pay increased rebates or shift other costs to us, limit or impact our decisions regarding the pricing of biopharmaceutical products or otherwise reduce the use of our U.S. products, such actions could have a material adverse effect on our business and results of operations.
We also face risks relating to the reporting of pricing data that affects the reimbursement of and discounts provided for our products. Government price reporting regulations are complex and may require a manufacturer to update certain previously submitted data. If our submitted pricing data are incorrect, we may become subject to substantial fines and penalties or other government enforcement actions, which could have a material adverse effect on our business and results of operations. In addition, as a result of restating previously reported price data, we also may be required to pay additional rebates and provide additional discounts.
—Changing reimbursement and pricing actions in various states may impact access to and have impacted and may continue to impact sales of our products
At the state level, government actions or ballot initiatives can also affect how our products are covered and reimbursed and/or create additional pressure on our pricing decisions. A number of states have adopted, and many other states have discussed and debated and are considering, new pricing actions, including proposals designed to require biopharmaceutical manufacturers to publicly report proprietary pricing information, limit price increases or to place a maximum price ceiling or cap on biopharmaceutical products. Existing and proposed state pricing laws have added complexity to the pricing of drugs and may already be impacting industry pricing decisions. For example, in October 2017, California enacted a drug-pricing transparency bill that requires biopharmaceutical manufacturers to notify health insurers and government health plans at least 60 days before scheduled prescription drug price increases that exceed certain thresholds. Oregon and Washington passed similar laws in 2019. Other states are seeking to change the way they pay for drugs for patients covered by state programs. For example, in August 2018 the Ohio Department of Medicaid ordered that all the state’s Medicaid managed care plans terminate and renegotiate contracts with Pharmacy Benefit Managers (PBMs) to eliminate PBMs billing the state more than treatments that they reimburse pharmacists for Medicaid patient prescriptions. In January 2019, California’s governor issued an executive order expanding state Medicaid coverage and directing its agencies and programs to consolidate drug purchases and to negotiate drug prices with manufacturers.

In addition, New York, Massachusetts, and Ohio have established Medicaid drug spending caps that require supplemental rebates for drugs that exceed specified spending thresholds. Additionally, some states, including Colorado, Florida, Maine and Vermont, have enacted laws, and several other states have proposed laws, to facilitate the importation of drugs from Canada. These state importation programs must first be approved by the U.S. Department of Health and Human Services under a federal statute that excludes biologics, but state and federal legislatures and agencies may seek ways to extend such measures to biologics. Other states could adopt similar approaches or could pursue different policy changes in a continuing effort to reduce their costs. Ultimately, as with U.S. federal government actions, existing or future state government actions or ballot initiatives may also have a material adverse effect on our product sales, business and results of operations.
—U.S. commercial payer actions have impacted and may continue to impact access to and sales of our products
Payers, including healthcare insurers, PBMs, integrated healthcare delivery systems and group purchasing organizations, increasingly seek ways to reduce their costs. With increasing frequency, payers are adopting benefit plan changes that shift a greater portion of drug costs to patients. Such measures include more limited benefit plan designs, high deductible plans, higher patient co-pay or coinsurance obligations and more significant limitations on patients’ use of manufacturer commercial co-pay payment assistance programs (including through co-pay accumulator adjustment or maximization programs). Payers have sought and have continued to seek price discounts or rebates in connection with the placement of our products on their formularies or those they manage, particularly in treatment areas where the payer has taken the position that multiple branded products are therapeutically comparable. Payers also control costs by imposing restrictions on access to or usage of our products, such as Step Therapy or requiring that patients receive the payer’s prior authorization before covering the product, or that patients use a mail-order pharmacy or a limited network of fully-owned specialty pharmacies; payers may also choose to exclude certain indications for which our products are approved or even choose to exclude coverage entirely. For example, the burdensome administrative processes required for physicians to demonstrate or document that the patients for whom Repatha® has been prescribed meet payer utilization management criteria has limited and may continue to limit patient access to Repatha® treatment. In an effort to reduce barriers to access, we reduced the net price of Repatha® by providing greater discounts and rebates to payers, including PBMs that administer Medicare Part D prescription drug plans. However, affordability of patient out-of-pocket co-pay cost has and may continue to limit patient use. For example, a very high percentage of Medicare patients have abandoned their Repatha® prescriptions rather than pay their co-pay payment. In late 2018 and early 2019, we introduced a set of new National Drug Codes (NDCs) to make Repatha® available at a lower list price to attempt to address affordability for patients, particularly those on Medicare. To allow payers time to make a smooth transition to the lower list price and avoid incentivizing PBMs to immediately switch patients to the other available PCSK9 inhibitor that offered them a higher overall rebate due to its higher list price, we also continued to offer Repatha® at the original list price for a period of time. Despite these net and list price reductions, some payers have and may continue to restrict patient access, change formulary coverage for Repatha®, seek further discounts or rebates or take other actions that could reduce our sales of Repatha®. Further, in the competitive PCSK9 inhibitor marketplace, many payers have not yet adopted the new NDCs we introduced for lower-list price Repatha®, including a number of PBMs that continue to cover Repatha® at the original list price in part because of the higher rebates they receive for it. These factors have and may continue to limit patient affordability and use and to negatively impact our sales of Repatha®.
Further, significant consolidation in the health insurance industry has resulted in a few large insurers and PBMs exerting greater pressure in pricing and usage negotiations with drug manufacturers, significantly increasing discounts and rebates required of manufacturers and limiting patient access and usage. For example, in the United States, in 2018, the top three PBMs oversaw greater than two-thirds of prescription claims as well as government and commercial covered lives. The consolidation among insurers, PBMs and other payers, including through integrated healthcare delivery systems and/or with specialty or mail-order pharmacies and pharmacy retailers, has increased the negotiating leverage such entities have over us and other drug manufacturers and has resulted in greater price discounts, rebates and fees for other services being realized by those payers. For example, during the fourth quarter of 2018, two of the nation’s largest PBMs, Express Scripts and CVS Health, completed their combinations with major insurance companies Cigna and Aetna, respectively. Additional consolidation would further increase the leverage of such entities. Ultimately, additional discounts, rebates, coverage or plan changes, restrictions or exclusions imposed by these commercial payers could have a material adverse effect on our product sales, business and results of operations.
—Government and commercial payer actions outside the United States have impacted and will continue to impact access to and sales of our products
Outside the United States, we expect countries will continue to take actions to reduce their drug expenditures. See our Annual Report on Form 10-K for the year ended December 31, 2018, Part I, Item 1. Business—Reimbursement. International reference pricing (IRP) has been widely used by many countries outside the United States to control costs based on an external benchmark of a product’s price in other countries. IRP policies can quickly and frequently change and may not reflect differences in the burden of disease, indications, market structures, or affordability differences across countries or regions. In addition, countries may refuse to reimburse or may restrict the reimbursed population for a product when their national health technology assessments do not consider a medicine to demonstrate sufficient clinical benefit beyond existing therapies or that it does not meet certain cost

effectiveness thresholds. For example, despite the EMA’s May 2018 approval of Repatha® for the treatment of patients with established atherosclerotic disease, reimbursement for Repatha® in France and Germany has remained limited to narrower patient populations (such as those with homozygous familial hypercholesterolemia) following national health technology assessments in mid-2018. Some countries decide on reimbursement between potentially competing products through national or regional tenders that often result in one product receiving most or all of the sales in that country or region. Failure to obtain coverage and reimbursement for our products, a deterioration in their existing coverage and reimbursement, or a decline in the timeliness or certainty of payment by payers to physicians and other providers has impacted and may further negatively impact the ability or willingness of healthcare providers to prescribe our products for their patients and otherwise negatively affect the use of our products or the prices we receive for them. Such changes can and have had a material adverse effect on our product sales, business and results of operations.
Our efforts to acquire other companies or products and to integrate their operations may not be successful, and may result in unanticipated costs, delays or failures to realize the benefits of the transactions.
We seek innovation through significant investment in both internal R&D and external transactions including collaborations, partnering, alliances, licenses, joint ventures, mergers and acquisitions (acquisition activity). We have an ongoing process of evaluating such potential acquisition activity opportunities that we expect will contribute to our future growth and expand our geographic footprint, product offerings and/or our R&D pipeline. For example, in late August 2019, we announced that we entered into an agreement with Celgene to acquire worldwide rights to Otezla® and certain related assets and liabilities (see Part I, Item 2. Management’s Discussion and Analysis of Financial Condition and Results of Operations—Significant developments).
Acquisition activities may be subject to regulatory approvals or other requirements that are not within our control. For example, the merger between BMS and Celgene, including the required divestiture of Otezla®, is contingent upon and subject to approval by the Federal Trade Commission (FTC) via a divestiture order. Our role as the acquirer of Otezla® pursuant to that order is also subject to FTC approval. There can be no assurance that such regulatory or other approvals will be obtained or that all closing conditions required in connection with the Otezla® acquisition will be satisfied or waived, which could result in us being unable to complete the planned acquisition.
Acquisition activities are complex, time consuming and expensive, and may result in unanticipated costs, delays or other operational or financial problems related to integrating the acquired company and business with our company, which may divert our management’s attention from other business issues and opportunities and restrict the full realization of the anticipated benefits of such transactions within the expected timeframe or at all. We may pay substantial amounts of cash, incur debt or issue equity securities to pay for acquisition activities, which could adversely affect our liquidity or result in dilution to our stockholders, respectively. Further, failures or difficulties in integrating or retaining new personnel or in integrating the operations of the businesses, products or assets we acquire (including related technology, commercial operations, compliance programs, manufacturing, distribution and general business operations and procedures) may affect our ability to realize the benefits of the transaction and grow our business, and may result in us incurring asset impairment or restructuring charges. These and/or other challenges may arise in connection with our planned acquisition of Otezla® or other acquisition activities, which could have a material adverse effect on our business, results of operations and stock price.
