NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS
SeptemberJune 30, 20172018
(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 one business segment: human therapeutics.
Basis of presentation
The financial information for the three and ninesix months ended SeptemberJune 30, 20172018 and 2016,2017, 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, 2016,2017, and with our condensed consolidated financial statements and the notes thereto contained in our Quarterly ReportsReport on Form 10-Q for the periodsperiod ended March 31, 2017 and June 30, 2017.2018.
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 any variable 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 $7.5$7.8 billion and $7.6 billion as of SeptemberJune 30, 20172018 and December 31, 2016.2017, respectively.
Recent accounting pronouncementsRevenues
Adoption of new revenue recognition standard
In May 2014, the Financial Accounting Standards Board (FASB) issued a new accounting standard that amends the guidance for the recognition of revenue from contracts with customers to transfer goods and services. The FASB has subsequently issued additional, clarifying standards to address issues arising from implementation of the new revenue recognition standard. The new revenue recognition standard and clarifying standards are effectiverequire an entity to recognize revenue when control of promised goods or services is transferred to the customer at an amount that reflects the consideration to which the entity expects to be entitled in exchange for interim and annualthose goods or services. We adopted this new standard as of January 1, 2018, by applying the modified-retrospective method to those contracts that were not completed as of that date.
The results for reporting periods beginning onafter January 1, 2018. The2018, are presented in accordance with the new standards are requiredstandard, although comparative information has not been restated and continues to be adopted using eitherreported under the accounting standards and policies in effect for those periods. See Note 1, Summary of significant accounting policies, to the consolidated financial statements in our Annual Report on Form 10-K for the year ended December 31, 2017.
Upon adoption, we recorded a full-retrospective ornet decrease of $25 million to Accumulated deficit due to the cumulative impact of adopting the new standard—with the impact related primarily to the acceleration of deferred revenue, net of related deferred tax impact. The adoption of this new standard had an immaterial impact on our reported total revenues and operating income as compared to what reported amounts would have been under the prior standard, and we expect the impact of adoption in future periods to be immaterial. Our accounting policies under the new standard were applied prospectively and are described below. See Note 4, Revenues.

Product sales and sales deductions
Revenue from product sales is recognized upon transfer of control of a modified-retrospective approach. Weproduct to a customer, generally upon delivery, based on an amount that reflects the consideration to which we expect to adopt this standardbe entitled, net of accruals for estimated rebates, wholesaler chargebacks, discounts and other deductions (collectively, sales deductions) and returns established at the time of sale.
We analyze the adequacy of our accruals for sales deductions quarterly. Amounts accrued for sales deductions are adjusted when trends or significant events indicate that an adjustment is appropriate. Accruals are also adjusted to reflect actual results. Accruals for sales deductions are based primarily on estimates of the amounts earned or to be claimed on the related sales. These estimates take into consideration current contractual and statutory requirements, specific known market events and trends, internal and external historical data and forecasted customer buying patterns. Sales deductions are substantially product specific and therefore, for any given period, can be affected by using the modified-retrospective approach beginningmix of products sold. Included in 2018. Wesales deductions are immaterial net adjustments related to prior-period sales due to changes in estimates. Historically, such amounts have completed our impact assessmentrepresented less than 1% of the aggregate sales deductions charged against product sales.
Returns are estimated through comparison of historical return data to their related sales on a production lot basis. Historical rates of return are determined for each product and do not currently anticipateare adjusted for known or expected changes in the marketplace specific to each product, when appropriate. Historically, sales return provisions have amounted to less than 1% of gross product sales. Changes in estimates for prior-period sales return provisions have historically been insignificant.
Taxes collected from customers and remitted to government authorities and that are related to sales of the Company’s products, primarily in Europe, are excluded from revenues.
As a material impact on Total revenuespractical expedient, sales commissions are expensed when incurred because the amortization period would have been one year or less. These costs are recorded in ourSelling, general and administrative expenses in the Condensed Consolidated Statements of Income. We
Other revenues
Other revenues consist primarily of royalty income and corporate partner revenues. Royalties from licensees are implementing changesbased on third-party sales of licensed products and are recorded when the related third-party product sale occurs. Royalty estimates are based on historical and forecasted sales trends. Corporate partner revenues are composed primarily of license fees and milestones earned and our share of commercial profits generated from collaborations. See Arrangements with multiple-performance obligations, discussed below.
Arrangements with multiple-performance obligations
From time to time, we enter into arrangements for the research and development (R&D), manufacture and/or commercialization of products and product candidates. Such arrangements may require us to deliver various rights, services and/or goods, including (i) intellectual property rights or licenses; (ii) R&D services; (iii) manufacturing services; and/or (iv) commercialization services. The underlying terms of these arrangements generally provide for consideration to Amgen in the form of nonrefundable, up-front license payments, R&D and commercial performance milestone payments, cost sharing and/or royalty payments.
In arrangements involving more than one performance obligation, each required performance obligation is evaluated to determine whether it qualifies as a distinct performance obligation based on whether (i) the customer can benefit from the good or service either on its own or together with other resources that are readily available and (ii) the good or service is separately identifiable from other promises in the contract. The consideration under the arrangement is then allocated to each separate distinct performance obligation based on its respective relative stand-alone selling price. The estimated selling price of each deliverable reflects our best estimate of what the selling price would be if the deliverable was regularly sold by us on a stand-alone basis or using an adjusted market assessment approach if selling price on a stand-alone basis is not available.
The consideration allocated to each distinct performance obligation is recognized as revenue when control of the related goods or services is transferred. Consideration associated with at-risk substantive performance milestones is recognized as revenue when it is probable that a significant reversal of the cumulative revenue recognized will not occur.
Other recent accounting policies, business processes, internal controls and disclosures to support the new accounting, however these changes are not expected to be significant.pronouncements
In January 2016, the FASB issued a new accounting standard that amends the accounting and disclosures of financial instruments, including a provision requiring that equity investments (except for investments accounted for under the equity method of accounting) be measured at fair value, with changes in fair value recognized in current earnings. The new standard is effective for interim and annual periods beginning on January 1, 2018. With the exception of equity investments currently beingthat were previously accounted for at cost, adjustments are applied using a modified-retrospective approach by reflecting adjustments through a cumulative-effect impact on retained earningswas used to reflect the cumulative effect of adoption as an adjustment to Accumulated deficit as of the beginning of the fiscal year of adoption.year. The new standard will be applied prospectively to investments currentlythat were previously accounted for at cost. Upon adoption, on January 1, 2018, we recorded an immaterial adjustment to Accumulated deficit from Accumulated other comprehensive income (loss) (AOCI), which represented

the net unrealized gain on all equity investments with a readily determinable fair value as of December 31, 2017. The impact that this new standard will havehas on our consolidated financial statementsCondensed Consolidated Statements of Income after adoption will depend on thechanges in fair valuevalues of available-for-sale equity securities in our portfolio in the future. See Note 6, Available-for-sale investments,8, Investments.
In October 2016, the FASB issued a new accounting standard that amends the income tax accounting guidance for intra-entity transfers of assets other than inventory. The new standard requires that entities recognize the income tax consequences of an intercompany transfer of an asset, other than inventory, in the period the transfer occurs. The current exception to defer the recognition of any tax impact on intercompany transfers of inventory until the inventory is sold to a third party remains unaffected. We adopted this standard as of January 1, 2018, and will apply it prospectively to any transaction occurring on or after the adoption date. The adoption of this standard did not have a material impact on our condensed consolidated financial statements, however the impact on our condensed consolidated financial statements in future periods will depend on the facts and circumstances of future transactions.
In March 2018, the FASB issued a new accounting standard to incorporate Securities and Exchange Commission (SEC) Staff Accounting Bulletin No. 118 (SAB 118), which addresses accounting implications of major tax reform legislation Public Law No. 115-97, commonly referred to as the Tax Cuts and Jobs Act (the 2017 Tax Act), enacted on December 22, 2017. SAB 118 allows a company to record provisional amounts during a measurement period not to extend beyond one year of the enactment date and was effective upon issuance. We continue to analyze the 2017 Tax Act, and in certain areas, have made reasonable estimates of the effects on our condensed consolidated financial statements and tax disclosures. See Note 5, Income taxes.
In August 2017, the FASB issued a new accounting standard that amends the accounting and reporting of hedging activities, which we elected to adopt early during the second quarter of 2018. Among its provisions, the new standard: (i) eliminates the separate measurement and reporting of hedge ineffectiveness and (ii) permits an entity to recognize in earnings the initial fair value of an excluded component of a hedging instrument’s fair value under a systematic and rational method over the life of the derivative instrument. In accordance with the transition provisions of the new standard, the separate measurement of ineffectiveness for our cash flow hedging instruments existing as of the date of adoption is required to be eliminated through a cumulative-effect adjustment to Accumulated deficit as of January 1, 2018, the beginning of the fiscal year. The ineffective portions of our cash flow hedges were not material to our previously issued condensed consolidated financial statements. In addition, certain provisions in the guidance require modifications to existing presentation and disclosure requirements on a prospective basis. The adoption of this standard did not have a material impact on our condensed consolidated financial statements. See Note 14, Derivative instruments.
In January 2017, the FASB issued a new accounting standard that changes the definition of a business to assist entities with the evaluation of when a set of assets acquired or disposed of should be considered a business. The new standard requires that an entity evaluate whether substantially all of the fair value of equity securitiesthe gross assets acquired is concentrated in a single identifiable asset or group of similar identifiable assets; if so, the set of assets would not be considered a business. The new standard also requires that a business include at least one substantive process, and it narrows the definition of outputs. We adopted this standard as of September 30, 2017.

January 1, 2018, and will apply it prospectively. Adoption of this new standard may result in more transactions being accounted for as asset acquisitions versus business combinations; however, the impact on our condensed consolidated financial statements in future periods will depend on the facts and circumstances of future transactions.
In February 2016, the FASB issued a new accounting standard that amends the guidance for the accounting and disclosure of leases. This new standard requires that lessees recognize on the balance sheet the assets and liabilities that arise from leases, on the balance sheet, including leases classified as operating leases under current GAAP, and disclose qualitative and quantitative information about leasing arrangements. The new standard requires a modified-retrospective approach to adoption and is effective for interim and annual periods beginning on January 1, 2019, but may be adopted earlier. We expect to adopt this standard beginning in the first quarter of 2019. We do not expect that this standard will have a material impact on our Condensed Consolidated Statements of Income, but we do expect that upon adoption, this standardit will have a material impact on our assets and liabilities on our Condensed Consolidated Balance Sheets. The primary effect of adoption will be the requirement to record right-of-use assets and corresponding lease obligationsobligation liabilities for current operating leases. In addition, the standard will requirerequires that we update ourthe systems, processes and controls we use to track, record and account for our lease portfolio. We have selected a lease accounting information system and engaged third-party consultants to provide system implementation services. System readiness, including the implementation and functionality of software procured from third-party providers, is essential to enable preparation of the financial information required for this standard.
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 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, beginning on January 1, 2019. With certain exceptions, adjustments are to be applied by 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 are currently evaluating the impact that this new standard will have on our condensed consolidated financial statements.
In October 2016, the FASB issued a new accounting standard that amends the income tax accounting guidance for intra-entity transfers of assets other than inventory. The new standard requires that entities recognize the income tax consequences of an intercompany transfer of an asset, other than inventory, in the period the transfer occurs. The current exception to defer the recognition of any tax impact on intercompany transfers of inventory until the inventory is sold to a third party remains unaffected. The new standard is effective for interim and annual periods beginning on January 1, 2018, but may be adopted earlier. We expect to adopt this standard beginning in 2018. The standard would be applied prospectively to any transaction occurring on or after the adoption date. We have completed our impact assessment and do not currently anticipate a material impact on our consolidated financial statements.
In January 2017, the FASB issued a new accounting standard that changes the definition of a business to assist entities with the evaluation of when a set of assets acquired or disposed of should be considered a business. The new standard requires that an entity evaluate whether substantially all of the fair value of the gross assets acquired is concentrated in a single identifiable asset or group of similar identifiable assets; if so, the set of assets would not be considered a business. The new standard also requires that a business include at least one substantive process and narrows the definition of outputs. The new standard will be applied prospectively and is effective for interim and annual periods beginning on January 1, 2018, but may be adopted earlier. We expect to adopt this standard beginning in 2018. Adoption of this new standard may result in more transactions being accounted for as asset acquisitions versus business combinations; however, the impact on our consolidated financial statements will depend on the facts and circumstances of future transactions.
2. Restructuring
In 2014, we initiated a restructuring plan to invest in both continuing innovation and the launch of our new pipeline molecules, while improving our cost structure. As part of the plan, we closed facilities in Washington State and Colorado and are reducing the number of buildings we occupy at our headquarters in Thousand Oaks, California, as well as at other locations.
We continue to estimate that we will incur $800 million to $900 million of pre-taxpretax charges in connection with our restructuring, including (i) separation and other headcount-related costs of $535$540 million to $585$600 million with respect to staff reductions and (ii) asset-related charges of $265$260 million to $315$300 million that consist primarily of asset impairments, accelerated depreciation and other related costs resulting from the consolidation of our worldwide facilities. Through SeptemberJune 30, 2017,2018, we incurred a total of $532$549 million of separation costs and other headcount-related costs and $239$245 million of net asset-related charges.
The amounts related to the restructuring recorded in the Condensed Consolidated Statements of Income during the three and ninesix months ended SeptemberJune 30, 20172018 and 2016,2017, were not significant. As of SeptemberJune 30, 2017,2018, the total restructuring liability was not significant.

3. Business combinations
Kirin-Amgen, Inc.
During the first quarter of 2018, we acquired the remaining 50% ownership of Kirin-Amgen, Inc. (K-A) from Kirin Holdings Company, Limited (Kirin), making K-A a wholly owned subsidiary of Amgen. Upon its acquisition, K-A’s operations have been included in our condensed consolidated financial statements commencing on the share acquisition date. The acquisition relieved Amgen of future royalty obligations to K-A.
K-A is a corporation that was established in 1984 as a 50-50 joint venture with Kirin to fund the global development of EPOGEN® (epoetin alfa). Over time, the scope of the collaboration was expanded to also include the products NEUPOGEN® (filgrastim), Neulasta® (pegfilgrastim), Aranesp® (darbepoetin alfa), Nplate® (romiplostim) and brodalumab. K-A held the intellectual property for each of these products and licensed the associated marketing rights in Asia to Kyowa Hakko Kirin (KHK), Kirin’s pharmaceutical subsidiary, and in most other territories to Amgen. In return, Amgen and KHK paid royalties to K-A, and K-A reimbursed Amgen and KHK’s R&D expenses. K-A had also given Johnson & Johnson (J&J) exclusive licenses to manufacture and market recombinant human erythropoietin for all geographic areas of the world outside the United States, China and Japan. Under this agreement, J&J pays royalties to K-A based on product sales.
Prior to the share acquisition date, we owned 50% of K-A and accounted for our interest in K-A by using the equity method of accounting, which included recording our share of K-A’s profits or losses in Selling, general and administrative expenses in the Condensed Consolidated Statements of Income. The carrying value of our equity method investment in K-A was $570 million as of December 31, 2017, and was included in Other assets in the Condensed Consolidated Balance Sheet.
The transaction was accounted for as a step acquisition of a business in which we were required to remeasure our existing 50% ownership interest at fair value. In addition, we were required to effectively settle our preexisting relationship with K-A, which resulted in a loss. Together the gain on the remeasurement of our existing ownership interest and the loss from the settlement of the preexisting relationship resulted in a net gain of $80 million, which was recorded in Interest and other income, net, in the Condensed Consolidated Statements of Income.
The primary means of consideration for this transaction was a payment of $780 million in cash. The aggregate share acquisition date consideration to acquire the remaining 50% ownership in K-A and the fair value of Amgen’s preacquisition investment consisted of the following (in millions):
  Amount
Total cash paid to Kirin $780
Fair value of contingent consideration obligation 45
Loss on settlement of preexisting relationship (168)
Total consideration transferred to acquire K-A 657
   
Fair value of Amgen’s investment in K-A 825
Total acquisition date fair value $1,482

3.In connection with this acquisition, we are obligated to make single-digit-percentage royalty payments to Kirin contingent upon sales of brodalumab. The estimated fair value of this contingent consideration obligation was $45 million as of the share acquisition date.
The fair values of assets acquired and liabilities assumed included cash of $977 million, licensing rights of $470 million, deferred tax liabilities of $102 million, other assets and liabilities of $131 million and goodwill of $6 million. The estimated fair value of acquired licensing rights was determined by 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 assets. The projected cash flows were based on certain assumptions, including estimates of future revenues and expenses and the time and resources needed to maintain the assets through commercialization. The licensing rights will be amortized over a weighted-average period of four years by using the straight-line method. The excess of the share acquisition date consideration over the fair values assigned to the assets acquired and the liabilities assumed of $6 million was recorded as goodwill, which is not deductible for tax purposes. The $131 million in other assets and liabilities represents primarily receivables for royalties earned by K-A but not yet received, offset partially by payables representing R&D expenses incurred but not yet reimbursed by K-A. The fair value estimates for the assets acquired and liabilities assumed were based on preliminary calculations and valuations, and our estimates and assumptions are subject to change as we obtain additional information during the measurement period (up to one year from the share acquisition date). The primary areas of those preliminary estimates that are not yet finalized relate to tax-related items.
Pro forma results of operations for this acquisition have not been presented because this acquisition is not material to our consolidated results of operations.

Prior-period amounts are not adjusted under the modified-retrospective method of adoption.
Financing and payment
Our payment terms vary by types and locations of customers and the products or services offered. Payment terms differ by jurisdiction and customer, but payment is generally required in a term ranging from 30 to 120 days from date of shipment or satisfaction of the performance obligation.
For certain products or services and certain customer types, we may require payment before products are delivered or services are rendered to customers.
Optional exemptions
We do not disclose the value of unsatisfied performance obligations for (i) contracts with original expected lengths of one year or less or (ii) contracts for which we recognize revenue at the amount to which we have the right to invoice for the services performed.
5. Income taxes
The effective tax rates for the three and ninesix months ended SeptemberJune 30, 2017,2018, were 15.1%13.3% and 15.4%12.5%, respectively, compared with 16.6%15.4% and 15.9%15.6%, respectively, for the corresponding periods of the prior year. The effective rates differ from the federal statutory rates primarily as a result of indefinitely invested earnings of our foreign operations. We do not provide for U.S. income taxes on undistributed earnings of our foreign operations that are intended to be invested indefinitely outside the United States.
The decrease in our effective tax rate for the three and six months ended SeptemberJune 30, 2017,2018, was due primarily to favorable taxthe impacts of changes in the jurisdictional mix of income and expenses, as well as discrete benefits associated with the impairment of our AMG 899 (formerly TA-8995) asset and the related release of contingent consideration liabilities connected with the acquisition of Dezima Pharma B.V. (Dezima) (see Note 8, Goodwill and other intangible assets and Note 11, Fair value measurement),U.S. corporate tax reform, offset partially by adjustments to certain federal tax credits and deductions.
The decrease in our effective tax rate for the nine months ended September 30, 2017, was due primarily to favorable tax impacts of changes in the jurisdictional mix of income and expenses, as well as discrete benefitsa prior year benefit associated with the effective settlement of certain state and federal tax matters, offset partially by lowermatters.
On December 22, 2017, the United States enacted the 2017 Tax Act, which imposes a repatriation tax on accumulated earnings of foreign subsidiaries, implements a hybrid territorial tax system together with a current tax on certain foreign earnings and lowers the general corporate income tax rate to 21%. In March 2018, the FASB issued a new accounting standard to incorporate SAB 118, which permits us to record provisional amounts during a measurement period not to extend beyond one year of the enactment date. We continue to analyze the 2017 Tax Act and in certain areas have made reasonable estimates of the effects on our condensed consolidated financial statements and tax disclosures.
The 2017 Tax Act includes U.S. taxation on certain foreign earnings, referred to as Global Intangible Low-Taxed Income (foreign intangible income), effective January 1, 2018. The FASB allows an entity to make an accounting policy election to either recognize deferred taxes for temporary basis differences expected to reverse as foreign intangible income in future years or provide for the tax expense related to the foreign intangible income as a period expense in the year it is incurred. We have recorded no provisional amount for deferred taxes on foreign intangible income because more time is needed to analyze the data in order to make an accounting policy election.

We consider our key estimates on the repatriation tax, the net deferred tax remeasurement, the impact on our unrealized tax benefits from share-based compensation payments and adjustmentsthe accounting policy election on temporary basis differences related to certain federalforeign intangible income to be incomplete due to our continuing analysis of final year-end data and tax creditspositions. We are still accumulating and deductions.processing data to update our underlying calculations, and we expect the U.S. Treasury and regulators may issue further guidance, among other things; therefore, our estimates may change during 2018. However, we expect to complete our analysis within the measurement period.
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 isof 4% and 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 audited 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. We are in discussions withOn November 29, 2017, we received a modified RAR that revised the IRS examination team and understand that the RAR may be modified.calculations but continued to propose substantial adjustments. We disagree with the proposed adjustments and are pursuing resolution through the IRS administrative appeals process, which we believe will likely not be concluded within the next 12 months. Final resolution of the IRS audit could have a material impact on our results of operations and cash flows if not resolved favorably, however, we believe our income tax reserves are appropriately provided for all open tax years. We are no longer subject to U.S. federal income tax examinations for years ended on or before December 31, 2009. In addition, weWe are currently under examination by a number of other state and foreign tax jurisdictions.

During the three and ninesix months ended SeptemberJune 30, 2017,2018, the gross amounts of our unrecognized tax benefits (UTBs) increased approximately $120$80 million and $345$155 million, respectively, as a result of tax positions taken during the current year. Substantially all of the UTBs as of SeptemberJune 30, 2017,2018, if recognized, would affect our effective tax rate.


4.6. 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, as determined by using the treasury stock method (collectively, dilutive securities).
The computations for basic and diluted EPS were as follows (in millions, except per shareper-share data):

7. Collaborations
A collaborative arrangement is a contractual arrangement that involves a joint operating activity. Such arrangements involve two or more parties that are both:both (i) active participants in the activity and (ii) exposed to significant risks and rewards dependent on the commercial success of the activity.
From time to time, we enter into collaborative arrangements for the research and development (R&D),R&D, manufacture and/or commercialization of products and/or product candidates. These collaborations generally provide for non-refundablenonrefundable up-front license fees, development and commercial performancecommercial-performance milestone payments, cost sharing, royalty payments and/or profit sharing. Our collaborativecollaboration arrangements are performed with no guarantee of either technological or commercial success, and each is unique in nature. The following describes a significant arrangement that had a material change since the filing of our Annual Report on Form 10-K for the year ended December 31, 2016.2017.
Novartis Pharma AG
In April 2017, we expanded our existing migraine collaboration with Novartis Pharma AG (Novartis), a wholly owned subsidiary of Novartis AG.. In the United States, Amgen and Novartis will jointly develop and collaborate on the commercialization of AimovigTM (erenumab)(erenumab -aooe). Amgen, as the principal, will recognizerecognizes product sales of AimovigTM in the United States, will shareshares U.S. commercialization costs with Novartis and will paypays Novartis a significant royalty on net sales in the United States. Novartis holds global co-development rights and exclusive commercial rights outside the United States and Japan.Japan for AimovigTM and other specified migraine programs. Novartis will paypays Amgen double-digit royalties on net sales of the products in the Novartis exclusive territories. Novartis will fundterritories and funds a portion of global R&D expenses. Novartis will also make payments to Amgen that could collectively exceed $400 million ifAs a result of certain regulatory events occur and commercial thresholds are achieved. Amgen will manufacture and supply Aimovig worldwide.
The migraine collaboration will continue for the commercial life of the products unless terminated in accordance with its terms.
Duringevents, during the three months ended SeptemberJune 30, 2017 and 2016, costs recovered from Novartis for the migraine products were $29 million and $6 million, respectively. During the nine months ended September 30, 2017 and 2016, costs recovered from Novartis for the migraine products were $86 million and $26 million, respectively. Costs recovered are included primarily in Research and development expense in the Condensed Consolidated Statements of Income. During the three months ended September 30, 2017,2018, we received a milestone payment of $60$148 million from Novartis, which was recorded in Other revenues in the Condensed Consolidated StatementsStatement of Income. In addition, Novartis will make payments to Amgen that could collectively amount to approximately $250 million if certain commercial thresholds are achieved with respect to AimovigTM in the United States. Amgen manufactures and supplies AimovigTM worldwide.
The migraine collaboration will continue for the commercial lives of the products unless terminated in accordance with its terms.

Other assets as of December 31, 2017, consisted of equity securities, which are no longer classified as available-for-sale.
As a result of the adoption of the new accounting standard related to the classification and measurement of financial instruments on January 1, 2018, equity investments (except for investments accounted for under the equity method of accounting) are now measured at fair value, with changes in fair value recognized in earnings. These investments were previously measured at fair value, with changes in fair value recognized in AOCI. Accordingly, these securities are no longer classified as available-for-sale and their presentation is not comparable to the presentation as of December 31, 2017. See Equity securities, discussed below, and Note 1, Summary of significant accounting policies.

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 and adverse conditions related specifically to the security, including 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 SeptemberJune 30, 20172018 and December 31, 2016,2017, 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 $200 million and $149 million as of June 30, 2018 and December 31, 2017, respectively, which are included in Other assets in the Condensed Consolidated Balance Sheets. As a result of the adoption of the new accounting standard related to the classification and measurement of financial instruments on January 1, 2018, equity investments (except for investments accounted for under the equity method of accounting) are now measured at fair value, with changes in fair value recognized in earnings. These investments were previously measured at fair value, with changes in fair value recognized in AOCI. Accordingly, these securities are no longer classified as available-for-sale and their presentation is not comparable to the presentation as of December 31, 2017. See Available-for-sale investments, discussed above, and Note 1, Summary of significant accounting policies. Gains and losses recognized on equity securities, including gains and losses recognized on sales, were not material for the three and six months ended June 30, 2018 and 2017.
Limited partnership investments
We held limited partnership investments of $266 million and $213 million as of June 30, 2018 and December 31, 2017, respectively, which are included in Other assets in the Condensed Consolidated Balance Sheets. These investments are measured by using the net asset values of the underlying investments as a practical expedient. These investments are typically redeemable only through distributions upon liquidation of the underlying assets. As of June 30, 2018, unfunded additional commitments to be made during the next several years for these investments were not material.

Developed product technologyDeveloped-product-technology rights consist of rights related to marketed products acquired in business combinations. Licensing rights consist primarily of contractual rights acquired in business combinations to receive future milestones, royaltiesmilestone, royalty and profit sharing payments,payments; capitalized payments to third parties for milestones related to regulatory approvals to commercialize productsproducts; and up-front payments associated with royalty obligations for marketed products. During the six months ended June 30, 2018, licensing rights increased due to the K-A share acquisition. See Note 3, Business combinations. Marketing-related intangible assets consist primarily of rights related to the sale and distribution of marketed products. R&D technology rights consist of technology used in R&D with alternative future uses.
In-process research and development (IPR&D) consists of R&D projects acquired in a business combination that are not complete at the time of acquisition due to remaining technological risks and/or lack of receipt of required regulatory approvals. During the three months ended September 30, 2017, we decided to discontinue the internal development of AMG 899 acquired in the acquisition of Dezima in 2015, resulting in an impairment charge of $400 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 Statement of Cash Flows. See Note 11, Fair value measurement, for the impact on the related contingent consideration liabilities. As of SeptemberJune 30, 2017,2018, IPR&D consists primarily of the primary IPR&Doprozomib project, is oprozomib, acquired in the acquisition of Onyx Pharmaceuticals, Inc., in 2013.
All IPR&D projects have major risks and uncertainties associated with the timely and successful completion of the development and commercialization of product candidates, including our ability to confirm safety and efficacy based on data from clinical trials, our ability to obtain necessary regulatory approvals and our ability to successfully complete these tasks within budgeted costs. We are not permitted to market a human therapeutic without obtaining regulatory approvals, and such approvals require the completion of clinical trials that demonstrate that a product candidate is safe and effective. In addition, the availability and extent of coverage and reimbursement from third-party payers, including government healthcare programs and private insurance plans as well as competitive product launches, impactaffect the revenues a product can generate. Consequently, the eventual realized value, if any, of the acquired IPR&D projects may vary from their estimated fair values. We review IPR&D projects for impairment annually, whenever events or changes in circumstances indicate that the carrying amountamounts may not be recoverable and upon the establishment of technological feasibility or regulatory approval.
During the three months ended SeptemberJune 30, 20172018 and 2016,2017, we recognized amortization chargesexpense associated with our finite-lived intangible assets of $308$332 million and $371 million, respectively. During both the ninesix months ended SeptemberJune 30, 20172018 and 2016,2017, we recognized amortization chargesexpense associated with our finite-lived intangible assets of $1.1 billion.$652 million and $744 million, respectively. Amortization of intangible assets is included primarily in Cost of sales in the Condensed Consolidated Statements of Income. The total estimated amortization chargesexpense for our finite-lived intangible assets for the remaining threesix months ending December 31, 2017,2018, and the years ending December 31, 2018, 2019, 2020, 2021, 2022 and 2022,2023, are $0.3$0.7 billion, $1.3 billion, $1.2 billion, $1.1 billion, $1.1$1.0 billion, $0.9 billion and $0.9 billion, respectively.

There are no material differences between the effective interest rates and coupon rates of any of our borrowings, except for the 4.563% 2048 Notes and the 4.663% 2051 Notes, which have effective interest rates of approximately 6.3% and 5.6%, respectively.
Debt repayments
During the nine months ended September 30, 2017, we repaid the $605 million short-term loan, the $1.25 billion aggregate principal amount of the 2.125% 2017 Notes, the $600 million aggregate principal amount of the Floating Rate Notes due 2017, the $850 million aggregate principal amount of the 1.25% 2017 Notes and the $1.1 billion aggregate principal amount of the 5.85% 2017 Notes.
Debt issuances
In May 2017, we issued a $3.5 billion principal amount of notes, consisting of the Floating Rate Notes due 2019, the 1.90% 2019 Notes, the Floating Rate Notes due 2020, the 2.20% 2020 Notes and the 2.65% 2022 Notes. In the event of a change-of-control triggering event, as defined in the terms of the notes, we may be required to purchase all or a portion of these debt securities at a price equal to 101% of the principal amount of the notes plus accrued and unpaid interest. All of the aforementioned fixed-rate notes may be redeemed at any time, in whole or in part, at the principal amount of the notes being redeemed plus accrued and unpaid interest and, except for the 2.65% 2022 Notes, a make-whole amount, which is defined by the terms of the notes. The 2.65% 2022 Notes may be redeemed without payment of the make-whole amount if redemption occurs on or after one month prior to maturity.
During the nine months ended September 30, 2017, we issued commercial paper under our commercial paper program. As of September 30, 2017, the weighted-average effective borrowing rate on outstanding commercial paper was 1.3%.

11.13. Fair value measurement
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 of five years 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- or equivalent by Moody’s Investors Service, Inc. (Moody’s), and BBB+ or equivalent by Standard & Poor’s Financial Services LLC (S&P), and A- or equivalent by Moody’s Investors Service, Inc. (Moody’s) or Fitch Ratings, Inc. (Fitch); and our corporate debt securities portfolio has a weighted-average credit rating of A- or equivalent by Fitch, and BBB + or equivalent by S&P or Moody’s. We estimate the fair values of these securities by taking into consideration valuations obtained from third-party pricing services. The pricing services utilizeuse 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/dealerbroker-dealer quotes on the same or similar securities; issuer credit spreads; benchmark securities; and other observable inputs.
Our residential mortgage-residential-mortgage-, other mortgage-other-mortgage- and asset-backed securitiesasset-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 utilizeuse 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/dealerbroker-dealer quotes on the same or similar securities; issuer credit spreads; benchmark securities; prepayment/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 derivativesderivative 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 Moody’s.Fitch. We estimate the fair values of these contracts by taking into consideration valuations obtained from a third-party valuation service that utilizesuses an income-based industry standard valuation model for which all significant inputs are observable, either directly or indirectly. TheThese inputs include foreign currency exchange rates, the London Interbank Offered RatesRate (LIBOR), swap rates and obligor credit default swap rates. In addition, inputs for our foreign currency option contracts include implied volatility measures. TheThese inputs, whenwhere applicable, are at commonly quoted intervals. See Note 12,14, 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 Moody’s.Fitch. We estimate the fair values of these contracts by taking into consideration valuations obtained from a third-party valuation service that utilizesuses an income-based industry standard valuation model for which all significant inputs are observable either directly or indirectly. TheThese inputs include foreign currency exchange rates, LIBOR, swap rates, obligor credit default swap rates and cross-currency basis swap spreads. See Note 12,14, 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 Moody’s.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. TheThese inputs includedinclude LIBOR, swap rates and obligor credit default swap rates. See Note 14, Derivative instruments.
Contingent consideration obligations
As a result of our business acquisitions, we incurred contingent consideration obligations, as discussed below. The contingent consideration obligations are recorded at their estimated fair values by using probability-adjusted discounted cash flows, and we revalue thethese 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 are reviewed quarterly by management in our R&D and commercial sales organizations. TheThese inputs include, as applicable, estimated probabilities and timing of achieving specified regulatory and commercial milestones and 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 were as follows (in millions):

As a result of our acquisition of Dezima in October 2015, we are obligated to pay its former shareholders up to $1.25 billion of additional consideration contingent upon achieving certain development and sales-related milestones and low single-digit royalties on net product sales above a certain threshold for AMG 899. The estimated fair value of the contingent consideration obligations had an aggregate value of $110 million at acquisition. During the three months ended September 30, 2017, we decided to discontinue the internal development of AMG 899, resulting in the release of the contingent consideration liabilities. The remeasurement of these liabilities of $116 million was recognized in Other operating expenses in the Condensed Consolidated Statements of Income and included in Other items, net in the Condensed Consolidated Statement of Cash Flows. See Note 8, Goodwill and other intangible assets, for the impact on the related IPR&D asset.

As a result of time.our acquisition of K-A in 2018, we are obligated to make single-digit-percentage royalty payments to Kirin contingent upon sales of brodalumab. See Note 3, Business combinations.
During the ninesix months ended SeptemberJune 30, 20172018 and 2016,2017, there were no transfers of assets or liabilities between fair value measurement levels, and except with respect to an IPR&D asset discussed in Note 8, Goodwill and other intangible assets, to the condensed consolidated financial statements, there were no material remeasurements ofto the fair values of assets and liabilities that are not measured at fair value on a recurring basis.

Summary of the fair values of other financial instruments
Cash equivalents
The estimated fair values of cash equivalents approximate their carrying values due to the short-term nature of such financial instruments.
Borrowings
We estimated the fair valuevalues of our borrowings (Level 2) by taking into consideration indicative prices obtained from a third-party financial institution that utilizes industry standard valuation models, including both income- and market-based approaches, for which all significant inputs are observable either directly or indirectly. These inputs include reported trades of and broker/dealer quotes on the same or similar securities; credit spreads; benchmark yields; foreign currency exchange rates, as applicable; and other observableusing Level 2 inputs. As of SeptemberJune 30, 20172018 and December 31, 2016,2017, the aggregate fair values of our borrowings were $39.0$36.0 billion and $36.5$38.6 billion, respectively, and the carrying values were $35.8$34.5 billion and $34.6$35.3 billion, respectively.
12.14. 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 utilizeuse or have utilizedused 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.
During the second quarter of 2018, we adopted early a new accounting standard that amends the accounting and reporting of hedging activities. 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.
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 onwith 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 SeptemberJune 30, 20172018 and December 31, 2016,2017, we had open foreign currency forward contracts with notional amounts of $4.0$4.8 billion and $3.4$4.6 billion, respectively, and open foreign currency option contracts with notional amounts of $131$21 million and $608$74 million, respectively. We have designated these foreign currency forward and foreign currency option contracts, which are primarily euro based, as cash flow hedges; and accordingly,hedges. Accordingly, we report the effective portions of the unrealized gains and losses on these contracts in AOCI in the Condensed Consolidated Balance Sheets, and we reclassify them to earningsProduct 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, and accordingly, the effective portions ofhedges. Accordingly, the unrealized gains and losses on these contracts are reported in AOCI in the Condensed Consolidated Balance Sheets and reclassified to earningsInterest and other income, net, in the Condensed Consolidated Statements of Income in the same periods during which the hedged debt affects earnings.

Derivatives not designated as hedges
To reduce our exposure to foreign currency fluctuations of certain assets and liabilities denominated in foreign currencies, we enter into foreign currency forward contracts that are not designated as hedging transactions. These exposures are hedged on a month-to-month basis. As of SeptemberJune 30, 20172018 and December 31, 2016,2017, the total notional amounts of these foreign currency forward contracts were $779$268 million and $666$757 million, respectively.

Our derivative contracts that were in liability positions as of SeptemberJune 30, 2017,2018, contain certain credit-risk-related contingent provisions that would be triggered if: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 thethese 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 for the nine months ended September 30, 2017 and 2016, are included within Net cash provided by operating activities in the Condensed Consolidated Statements of Cash Flows.
13.15. Contingencies and commitments
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, 2016,2017, 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 Note;footnote; in Note 18, Contingencies and commitments, to the consolidated financial statements in our Annual Report on Form 10-K for the year ended December 31, 2016;2017; and in Notes 12 and 13,Note 14, Contingencies and commitments, to the condensed consolidated financial statements in our Quarterly ReportsReport on Form 10-Q for the periodsperiod ended March 31, 2017 and June 30, 2017, respectively.2018.
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 range from cases brought by a single plaintiff to a class action with thousands of putative class members. These legal proceedings, as well as other matters, involve various aspects of our business and a variety of claims—including but not limited to patent validity and infringement, marketing, pricingregulatory standards, and trade practices and securities law—other matters—some of which present novel factual allegations and/or unique legal theories.In each of the matters described in this filing, in Note 18, Contingencies and commitments, to ourthe consolidated financial statements in our Annual Report on Form 10-K for the year ended December 31, 2016,2017, or in Notes 12 or 13,Note 14, Contingencies and commitments, to ourthe condensed consolidated financial statements in our Quarterly ReportsReport on Form 10-Q for the periods endedperiod ending March 31, 2017 and June 30, 2017, respectively,2018, plaintiffs 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, (whichwhich in complex proceedings of the sort faced by uswe face often extend for several years).years. As a result, none of the matters pending against us described in this filing, in Note 18, Contingencies and commitments, to ourthe consolidated financial statements in our Annual Report on Form 10-K for the year ended December 31, 2016,2017, or in Notes 12 or 13,Note 14, Contingencies and

commitments, to ourthe condensed consolidated financial statements in our Quarterly ReportsReport on Form 10-Q for the periods endedperiod ending March 31, 2017 and June 30, 2017, respectively,2018, 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:

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 ninesix months ended SeptemberJune 30, 20172018 and 2016.2017.

Transformation and process improvements
During 2014, we announced transformation and process improvement efforts that we continue to execute. As part of these efforts, we committed to a more agile and efficient operating model. Our transformation and process improvement efforts across the Company are enabling us to reallocate resources to fund many of our innovative pipeline and growth opportunities that deliver value to patients and stockholders.
The transformation includes a restructuring plan that we continue to estimate will result in pre-taxpretax accounting charges in the range of $800 million to $900 million. As of SeptemberJune 30, 2017,2018, restructuring costs incurred to date were $771$794 million. The charges that were recorded related to the restructuring during the three and ninesix months ended SeptemberJune 30, 2017,2018, were not significant. Since 2014, we have realized approximately $1.3$1.6 billion of transformation and process improvement savings. Net savings have not been significant as savings were reinvested in product launches, clinical programs and external business development.
Puerto Rico operations
Since Hurricane Maria struck Puerto Rico in September 2017, we have been providing support to our staff members and the local community while implementing business continuity plans and restoring manufacturing operations at our site in Juncos. All of our staff in Puerto Rico have been accounted for and nearly all are back at work. Our drug substance manufacturing and packaging plants are fully operational and we expect to resume formulation/filling and small molecule commercial production by the end of October 2017. We continue to provide an uninterrupted supply of medicines for patients around the world.
We incurred $67 million of pre-tax expenses during the three months ended September 30, 2017, related to Hurricane Maria. In the three months ending December 31, 2017, we expect additional pre-tax expenses in the range of $75 million to $100 million. At this time, we do not expect significant pre-tax expenses in 2018. These estimates do not include possible insurance recoveries.
Cost of sales
Cost of sales decreased to 17.1% of total revenues for the three months ended September 30, 2017, driven primarily by a reduction in amortization of intangible assets and manufacturing efficiencies, offset partially by expenses related to Hurricane Maria.
Cost of sales decreased to 17.7% of total revenues for the nine months ended September 30, 2017, driven primarily by manufacturing efficiencies.
The excise tax imposed by the U.S. territory of Puerto Rico on the gross intercompany purchase price of goods and services from our manufacturer in Puerto Rico (Puerto Rico excise tax) is recorded as a cost of sales expense. Excluding the impact of the Puerto Rico excise tax, cost of sales would have been 15.6% and 16.1%16.9% of total revenues for the three and ninesix months ended SeptemberJune 30, 2017, respectively, compared with 16.1%2018, driven primarily by lower royalty costs and 16.5% for the corresponding periodsa decrease in acquisition-related amortization of the prior year.

The increase in Interest expense, net, for the ninethree and six months ended SeptemberJune 30, 2017,2018, was due primarily to a higher average amountthe impact of rising interest rates on debt outstanding.on which we pay variable rates of interest.
Interest and other income, net
The slight decrease in Interest and other income, net for the three months ended June 30, 2018, was due primarily to higher net investment losses and reduced returns as a result of the liquidation of a portion of our portfolio, substantially offset by gains recognized on our equity investments, principally as a result of the adoption of a new accounting standard in the current year that changed prospectively the accounting for equity investments (see Note 1, Summary of significant accounting policies, to the

condensed consolidated financial statements).

Income taxes
The decrease in our effective tax rate for the three and six months ended SeptemberJune 30, 2017,2018, was due primarily to favorable taxthe impacts of changes in the jurisdictional mix of income and expenses, as well as discrete benefits associated with the impairment of our AMG 899 asset and the related release of contingent consideration liabilities connected with the acquisition of Dezima,U.S. corporate tax reform, offset partially by adjustments to certain federal tax credits and deductions.

On December 22, 2017, the U.S. enacted the 2017 Tax Act, which imposes a repatriation tax on accumulated earnings of foreign subsidiaries, implements a hybrid territorial tax system together with a current tax on certain foreign earnings and lowers the general corporate income tax rate to 21%. In March 2018, the FASB issued a new accounting standard to incorporate SAB 118, which permits us to record provisional amounts during a measurement period not to extend beyond one year of the enactment date. We continue to analyze the 2017 Tax Act and in certain areas have made reasonable estimates of the effects on our condensed consolidated financial statements and tax disclosures.
The 2017 Tax Act includes U.S. taxation on foreign intangible income, effective January 1, 2018. The FASB allows an entity to make an accounting policy election to either recognize deferred taxes for temporary basis differences expected to reverse as foreign intangible income in future years or provide for the tax expense related to the foreign intangible income as a period expense in the year it is incurred. We have recorded no provisional amount for deferred taxes on foreign intangible income because more time is needed to analyze the data in order to make an accounting policy election.
We consider our key estimates on the repatriation tax, the net deferred tax remeasurement, the impact on our unrealized tax benefits from share-based compensation payments and adjustmentsthe accounting policy election on temporary basis differences related to certain federalforeign intangible income to be incomplete due to our continuing analysis of final year-end data and tax creditspositions. We are still accumulating and deductions.
Excludingprocessing data to update our underlying calculations, and we expect the impact ofU.S. Treasury and regulators may issue further guidance, among other things; therefore, our estimates may change during 2018. However, we expect to complete our analysis within the Puerto Rico excise tax, our effective tax rate for the three and nine months ended September 30, 2017, would have been 17.8% and 18.2%, respectively, compared with 19.4% and 18.8%, respectively, for the corresponding periods of the prior year.measurement period.
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. We are in discussions withOn November 29, 2017, we received a modified RAR that revised the IRS examination team and understand that the RAR may be modified.calculations but continued to propose substantial adjustments. We disagree with the proposed adjustments and are pursuing resolution through the IRS administrative appeals process, which we believe will likely not be concluded within the next 12 months. Final resolution of the IRS audit could have a material impact on our results of operations and cash flows if not resolved favorably, however, we believe our income tax reserves are appropriately provided for all open tax years.

Cash, cash equivalents and marketable securities
We have global access to our $29 billion balance of cash, cash equivalents and marketable securities, as we no longer reinvest our undistributed foreign earnings indefinitely outside the United States. As a result of the 2017 Tax Act, we recorded a repatriation tax liability on undistributed earnings generated from operations in foreign tax jurisdictions estimated at $7.3 billion, that will be paid over eight years. The first annual payment was made in April 2018.
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 share repurchases, payment of cash dividends, 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 and return capital to stockholders through the payment of cash dividends and stock repurchases reflecting our confidence in the future cash flows of our business. The timing and amountsamount of future dividends and stock repurchases will vary based on a number of factors, including future capital requirements for strategic transactions, the 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 agreements of the Company. In addition, the timing and amountsamount of stock repurchases may also be affected by the 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 July 2017, March 20172018 and December 2016,2017, the Board of Directors declared quarterly cash dividends of $1.15$1.32 per share of common stock, which were paid on SeptemberMarch 8, 2018 and June 8, and March 8, 2017, respectively. In October 2017, the Board of Directors declared a quarterly cash dividend of $1.15 per share of common stock, which will be paid on December 8, 2017.2018.
We have also returned capital to stockholders through our stock repurchase program. During the ninesix months ended SeptemberJune 30, 2017,2018, we repurchased $2.3$14.0 billion of our stock and paid $2.4$13.9 billion in cash during the period. Duringperiod, which included 52.1 million shares of common stock repurchased through a $10.0 billion tender offer. In April 2018, our Board of Directors increased the nine months ended September 30, 2016, we repurchased $2.0 billion ofamount authorized under our stock.stock repurchase program by an additional $5.0 billion.

As a result of Directors authorizedstock repurchases, including our recent tender offer, and quarterly dividend payments, we have an increase that resulted in a totalaccumulated deficit as of $5.0 billion available under theJune 30, 2018 and December 31, 2017. Our accumulated deficit is not expected to affect our future ability to operate, repurchase stock, repurchase program.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 our syndicated credit facilities and access to other domestic and foreign debt markets and equity markets. During the second quarter of 2017, we began borrowing under our $2.5 billion commercial paper program and as of September 30, 2017, we had $1.5 billion outstanding under this program.
With respect to our U.S. operations, we believe that existing funds intended for use in the United States; cash generated from our U.S. operations, including intercompany payments and receipts; and existing sources of and access to financing (collectively, U.S. funds) are adequate to continue meeting our U.S. obligations, including our plans to pay dividends and repurchase stock with U.S. funds, for the foreseeable future. See our Annual Report on Form 10-K for the year ended December 31, 2016,2017, Part I, Item 1A. Risk Factors—Global economic conditions may negatively affect us and may magnify certain risks that affect our business.
Of our cash, cash equivalents and marketable securities balances totaling $41.4 billion as of September 30, 2017, approximately $38.9 billion was generated from operations in foreign tax jurisdictions and is intended to be invested indefinitely outside the United States. Under current tax laws, if these funds were repatriated for use in our U.S. operations, we would be required to pay additional income taxes at the tax rates then in effect.business.
Certain of our financing arrangements contain non-financialnonfinancial covenants. In addition, our revolving credit agreement includes a financial covenant, with respectwhich was modified during the three months ended March 31, 2018. The modified covenant 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 level of our borrowings in relation to our equity, as defined.amended credit agreement. We were in compliance with all applicable covenants under these arrangements as of SeptemberJune 30, 2017.

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 ninesix months ended SeptemberJune 30, 2017,2018, increased compared with the same period in the prior year due primarily to an increase inhigher net income, offset partially by higher cash taxes resulting from the timingfirst installment payment of repatriation tax arising from the 2017 Tax Act, net of reduced payments to taxing authorities.on our ongoing income tax liability.
Investing
Cash provided by investing activities during the six months ended June 30, 2018, was due primarily to net activity related to marketable securities of $18.0 billion, offset partially by capital expenditures of $342 million. Cash used in investing activities during the ninesix months ended SeptemberJune 30, 2017, was due primarily to net activity related to marketable securities of $3.3$1.5 billion and capital expenditures of $511 million. Cash used in investing activities during the nine months ended September 30, 2016, was due primarily to net activity related to marketable securities of $6.7 billion and capital expenditures of $511$353 million. Capital expenditures during the ninesix months ended SeptemberJune 30, 20172018 and 2016,2017, were associated primarily with manufacturing capacitymanufacturing-capacity expansions in various locations, as well as other site developments. We currently estimate 20172018 spending on capital projects and equipment to be approximately $700$750 million.
Financing
Cash used in financing activities during the ninesix months ended SeptemberJune 30, 2018, was due primarily to repurchases of our common stock of $13.9 billion, payment of dividends of $1.8 billion and repayment of debt of $500 million. Cash used in financing activities during the six months ended June 30, 2017, was due primarily to the payment of dividends of $2.5$1.7 billion, repurchases of our common stock of $2.4$1.6 billion and repayment of long-term debt, net of proceeds from debt issuances, of $920 million, offset partially by net proceeds from the issuance of commercial paper of $1.5 billion. Cash used in financing activities during the nine months ended September 30, 2016, was due primarily to the payment of dividends of $2.3 billion and repurchases of our common stock of $2.0 billion, offset partially by proceeds from the issuance of long-term debt, net of repayments, of $4.0 billion.$959 million. See Note 9, Financing arrangements, and Note 10,12, 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, under different assumptions or conditions, actual results could differ materially from those estimates under different assumptions or conditions.estimates. A summary of our critical accounting policies is presented in Part II, Item 7. Management’s Discussion and Analysis of Financial Condition and Results of Operations, of our Annual Report on Form 10-K for the year ended December 31, 2016.2017. There were no material changes to our critical accounting policies during the ninesix months ended SeptemberJune 30, 2017.2018.
Item 3.QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK
Information about our market risk is disclosed in Part II, Item 7A. Quantitative and Qualitative Disclosures About Market Risk, of our Annual Report on Form 10-K for the year ended December 31, 2016,2017, and is incorporated herein by reference. Except as discussed below,There have been no material changes occurred during the ninesix months ended SeptemberJune 30, 2017,2018, to the information provided in Part II, Item 7A. Quantitative and Qualitative Disclosures About Market Risk, of our Annual Report on Form 10-K for the year ended December 31, 2016.
Interest rate sensitive financial instruments
To achieve a desired mix of fixed- and floating-interest-rate debt, we entered into interest rate swap contracts with an aggregate notional amount of $3.65 billion during the nine months ended September 30, 2017. In addition, we had interest rate swap contracts with an aggregate notional amount of $850 million mature during the nine months ended September 30, 2017. As of September 30, 2017, interest rate swap contracts with an aggregate notional amount of $9.45 billion were outstanding. These interest rate swap contracts effectively converted a fixed-interest-rate coupon to a floating-rate LIBOR-based coupon over the life of the

respective note. A hypothetical 100-basis-point increase in interest rates relative to interest rates at September 30, 2017, would have resulted in reductions in fair values of approximately $450 million on our interest rate swap contracts on this date and would not result in a material effect on the related income in the ensuing year. The analysis for the interest rate swap contracts does not consider the impact that hypothetical changes in interest rates would have on the related fair values of debt that these interest rate sensitive interests were designed to offset.
Item 4.CONTROLS AND PROCEDURES
We maintain “disclosure controls and procedures,” as such term is defined under 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 SeptemberJune 30, 2017.2018.
Management determined that, as of SeptemberJune 30, 2017,2018, 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.

Those discussions should be read in conjunction with Note 18, Contingencies and commitments, to the consolidated financial statements in Part IV of our Annual Report on Form 10-K for the year ended December 31, 2016.2017.
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 they involve certain risks, uncertainties and assumptions that are difficult to predict. You should carefully consider the risks and uncertainties our business faces. We have described in our Annual Report on Form 10-K for the fiscal year ended December 31, 2016,2017, the primary risks related to our business, and we periodically update those risks for material developments. Those risks 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.
Below, we are providing, in supplemental form, the material changes to our risk factors that occurred during the past quarter. Our risk factors disclosed in Part I, Item 1A. Risk Factors,1A, of our Annual Report, on Form 10-K for the year ended December 31, 2016, and in our Quarterly Reports on Form 10-Q for the periods ended March 31, 2017 and June 30, 2017, provide additional disclosure for these supplemental risks and are incorporated herein by reference.

Our sales depend on coverage and reimbursement from third-party payers, and pricing and reimbursement pressures may affect our profitability.
We perform a substantial majority of our commercial manufacturing activities at our facility in the U.S. territory of Puerto Rico and substantially all of our clinical manufacturing activities at our facility in Thousand Oaks, California; if significant disruptions or production failures occur at the Puerto Rico facility, we may not be able to supply these products or, at the Thousand Oaks facility, we may not be able to continue our clinical trials.
We currently perform a substantial majority of our commercial manufacturing activities at our facility in the U.S. territory of Puerto Rico and substantially all of our clinical manufacturing activities at our facility in Thousand Oaks, California. The global supplySales of our products and product candidates for commercial sales and for use in our clinical trials is significantly dependentdepend on the uninterruptedavailability and efficient operationextent of these facilities.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 increasingly 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 adverse effect on our business. In the United States, the public discussions of drug pricing issues are likely to continue.
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 U.S. federal and state governments. See our Annual Report on Form 10-K for the year ended December 31, 2016,2017, Part I, Item 1A. Risk Factors—Manufacturing difficulties, disruptions 1. Business—Reimbursement. Changes to U.S. federal reimbursement policy may come through legislative and/or delaysadministrative actions. For example, in February 2018, the U.S. Congress passed legislation that requires pharmaceutical manufacturers to pay greater discounts for patients in the Medicare Part D coverage gap beginning in 2019, which may reduce our net product sales relating to such patients. In May 2018, U.S. President Donald Trump and his administration released a drug pricing “blueprint” and requested public comment on 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. The blueprint included a number of policy ideas with the potential to significantly impact our industry, whether individually or collectively, including proposals to move reimbursement for all Medicare Part B drugs into Medicare Part D and to remove the safe-harbor protection under the federal anti-kickback statute for drug rebates paid to payers. Prior to the release of the drug pricing blueprint, other legislative proposals had been introduced into the U.S. Congress to overhaul provisions of the ACA and to enable commercial-level re-importation of prescription medications from Canada or other countries. Changes in U.S. federal reimbursement policy may also arise as a result of executive actions, federal regulations, or demonstration projects implemented by federal agencies including the Centers for Medicare & Medicaid Services (CMS), the federal agency responsible for administering Medicare, Medicaid and the Health Insurance Marketplaces. CMS has substantial power to implement policy changes or demonstration projects that can quickly and significantly affect how our products are covered and reimbursed. CMS has already begun implementing certain elements described in the administration’s drug pricing blueprint, including warning Medicare Part D plan insurers that they could face compliance actions if they implement contractual “gag clauses” to prevent pharmacies from alerting patients to lower priced cash payment options. CMS has also undertaken other projects to test care models, such as the CMS Oncology Care Model that 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 negatively impacted utilization of certain of our oncology products by participating physician practices and may continue to do so in the future. CMS has also solicited suggestions regarding other potential care models. President Trump’s administration is also seeking to address drug prices through other federal agency actions. For example, to promote greater drug price competition, the FDA is pursuing policies that would ease generic and biosimilar entry requirements, including the lowering of standards for demonstrating biosimilarity or interchangeability. While we are unable to predict if these policy, legislative or regulatory changes may ultimately be enacted, to the extent that these or other federal government initiatives decrease or modify the coverage or reimbursement available for our products, require that we pay increased rebates or shift other costs to us, limit supplyour ability to offer co-pay payment assistance to commercial patients, limit or impact our decisions regarding the pricing of pharmaceutical products or reduce the use of our U.S. products, such actions could have a material adverse effect on our business and results of operations.
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 legislation, 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 pharmaceutical products. For example, in October 2017, California enacted a drug pricing transparency bill that requires pharmaceutical manufacturers to notify health insurers and government health plans at least 60 days before scheduled prescription drug price increases that exceed certain thresholds. These existing and proposed state pricing laws have added complexity to the pricing of drugs and may already be impacting industry pricing decisions. Ultimately, as with U.S. federal government actions, existing or future state government actions may also have a material adverse effect on our business and results of operations.
Payers, including healthcare insurers, Pharmacy Benefit Managers (PBMs) and group purchasing organizations, increasingly seek ways to reduce their and their respective members’ costs. Many payers continue to adopt benefit plan changes that shift a greater portion of prescription costs to patients. Such measures include more limited benefit plan designs, high deductible plans, higher patient co-pay or co-insurance obligations and limitations on patients’ use of commercial manufacturer co-pay payment assistance programs (including through co-pay accumulator adjustment or maximization programs). Payers have sought and will likely continue 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 by requiring prior authorizations or step therapy, and may choose to exclude certain indications for which our products are approved or even choose to exclude coverage entirely. For example, the burdensome administrative process required for physicians to demonstrate or document that the patients for whom Repatha® has been prescribed meet the payers’ utilization management criteria has limited patient access to Repatha® treatment. Even with increased access, patient out-of-pocket expense may limit patient use. For example, other patients with coverage for Repatha® have abandoned their prescriptions rather than pay their co-pay payment. In an effort to reduce access burdens, we have taken a number of actions to reduce the net price of Repatha® through offering greater discounts and rebates to payers. Despite the recent net price reductions, payers may continue to impose access burdens, change formulary coverage for Repatha®, seek further discounts or rebates or take other actions that could reduce our product sales.sales of Repatha®.
In late September 2017, Hurricane Maria,Significant consolidation in the health insurance industry has resulted in a Category 4 storm, made landfall onfew 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 islandUnited States, the top three PBMs now oversee more than 70% of Puerto Rico. The hurricane destroyed residentialprescription claims and the top three health insurance companies’ coverage is approaching half of government and commercial buildings, agriculture, communications networkscovered lives. Consolidation between pharmacies is also increasing, with the top three pharmacies now responsible for half of U.S. drug sales. Consolidation among insurers, PBMs and most of Puerto Rico’s electric grid. The critical manufacturing areas ofother payers, including through integrated delivery systems and/or with specialty 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 on our commercial manufacturing facility were not significantly impacted by the storm,products, fees for other services and we are in the process of resuming our full manufacturing operations. Puerto Rico officials suggest that it may be months before electrical service is restored to much of the island, andrebates. Further consolidation (including as a result our facility is operating with electrical power from back-up diesel-powered generators. We are currently receiving regular deliveries of diesel fuel under pre-arranged contracts. In addition, suppliesa number of medical-grade oxygen and nitrogen used in biopharmaceutical manufacturing operations are limitedmerger transactions that have been announced but not yet completed) would increase this leverage. Ultimately, further discounts, rebates, coverage or plan changes, restrictions or exclusions as described above could have a material adverse effect on the island, and we have arranged deliveries of both gases from the U.S. mainland and other countries. However, it is possible that we may not be able to secure the fuel needed to continuously operate our back-up generators until electrical power is permanently restored or the medical-grade gases needed to continue our operations until a reliable supply chain can be established. Many locations on the island depend upon electricity to power the pumps that deliver clean water. The breakdown of infrastructure and basic services across the island, including communication (telephone, cellular and internet), transportation, utilities and sanitation, may also make it more difficult, time consuming and expensive for us to operate our manufacturing facility and to get supplies and manufactured products transported to and from that location. Even if our facility remains operable and accessible, it may become challenging for somesales of our local staff to return to work oraffected products.
Outside the United States, we expect countries will continue to work. While nearly all of our staff have already returnedtake actions to work, some of them orreduce their families may now or in the future be without housing, access to food and water, electricity, healthcare, childcare, transportation or other essentials, and for these or other reasons may be forced or elect to temporarily or permanently relocate elsewhere on or off the island. A substantial disruption in our ability to operate our Puerto Rico manufacturing facility (whether due to problems with the facility itself, the infrastructure and services available on the island, the unavailability of raw materials or supplies from vendors, the unavailability of key staff or otherwise) could materially and adversely affect our ability to supply our products and affect our product sales.drug expenditures. See our Annual Report on Form 10-K for the year ended December 31, 2016,2017, Part I, Item 1A. Risk Factors— Manufacturing difficulties, disruptions1. Business—Reimbursement. For example, international reference pricing (IRP) is widely used by a large number of countries 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 delaysaffordability differences across countries or regions. Any deterioration in the coverage and reimbursement available for our products or in the timeliness or certainty of payment by payers to physicians and other providers could limit supplynegatively impact the ability or willingness of healthcare providers to prescribe our products for their patients or could otherwise negatively affect the use of our products and limit our product sales.
The impact of Hurricane Maria is certain to place greater stress on the island’s already challenged economy. Since June 2015, when the Governor of Puerto Rico announced that the government (including certain government entities) was unable to pay its roughly $72 billion in debt, the government’s liquidity position has continued to deteriorate and public reports indicate that the Puerto Rico government is not making certain payments with respect to its obligations. On June 30, 2016, President Obama signed into law the Puerto Rico Oversight, Management, and Economic Stability Act (PROMESA) to provide a mechanism for Puerto Rico to restructure its debt, achieve fiscal responsibility and gain access to capital markets. PROMESA established a federal Financial Oversight and Management Board (Oversight Board) to provide fiscal oversight through the development and approval of fiscal plans and budgets for Puerto Rico and to assist in the debt restructuring. The establishment of the Oversight Board initially provided for an automatic stay of creditor actions against the Puerto Rico government until February 15, 2017, and subsequently extended the automatic stay until May 1, 2017, to pursue voluntary negotiations with the Puerto Rico government’s creditors. On May 3, 2017, after negotiations with creditors were unsuccessful and the automatic stay expired, the Oversight Board approved and certified the filing in the U.S. District Court for the District of Puerto Rico of a voluntary petition under Title III of PROMESA for the government of Puerto Rico, following thereafter with similar filings for certain Puerto Rico government entities. Title III of PROMESA provides Puerto Rico with a judicial process for restructuring its debt similar to, but not identical to, Chapter 9 of the U.S. Bankruptcy Code. Given the severe conditions in Puerto Rico after Hurricane Maria hit the island, it is expected that resolution of Puerto Rico’s outstanding debt situation through the PROMESA judicial process will be delayed pending recovery efforts. Additionally, on January 29, 2017, the Puerto Rico government enacted the Puerto Rico Fiscal Emergency and Fiscal Responsibility Act, which, among other things, declared a state of financial emergency in Puerto Rico until May 1, 2017, and authorizes the Governor to designate certain services as essential services, and other services as non-essential in order to prioritize the use of available resources to satisfy Puerto Rico’s obligations. On July 19, 2017, the Puerto Rico government extended the emergency period through December 31, 2017, and authorized the Governor to further extend the emergency period for six-month terms under certain conditions. While PROMESA and the actions above continue to be important factors in moving Puerto Rico toward economic stability, there is still a risk that Puerto Rico’s economic situation prior to Hurricane Maria, as well as the severe impact to the island from the hurricane, could impact the territorial government’s provision of utilities or other services in Puerto

Rico that we use in the operation of our business, create the potential for increased taxes or fees to operate in Puerto Rico, result in a migration of workers from Puerto Rico to the mainland United States, and/or make it more expensive or difficult for us to operate in Puerto Rico.
We are increasingly dependent on information technology systems, infrastructure, network connected control systems and data security.
We are increasingly dependent on information technology systems, infrastructure, network connected control systems and data security. The breadth, complexity and business process integration of our computer systems and the potential value of our data make these systems targets of service interruption, destruction, malicious intrusion and attack. Likewise, data privacy or security breaches by employees, contractors or others may pose risks that sensitive data, including intellectual property, trade secrets or personal information belonging us, our patients, customers and/or other business partners, may be exposed to unauthorized persons or the public. As a global biotechnology company, our systems, those of our third-party service providers, and those of key business partners with whichprices we interact are subject to frequent cyber-attacks. Moreover, as the cyber-threat landscape evolves, these attacks are growing in frequency, sophistication and intensity, and are becoming increasingly difficult to detect.receive for them. Such attackschanges could include the deployment of harmful and virulent malware, key loggers, a denial-of-service, delivery of malware through malicious websites, the use of social engineering and/or other means to disrupt business operations or affect the confidentiality, integrity and availability of our information technology systems, processes, infrastructure and data. For example, a number of recent high-profile cyber-attacks against multi-national peer companies, contractors and government agencies have significantly disrupted business operations or resulted in substantial breaches of personal information. Key business partners, third-party service and product providers and any companies we may acquire face similar risks, and any security breaches of their systems could adversely affect our security, expose our confidential data or leave us without access to important systems, products, raw materials, components, services or information. Although in the past we have experienced cyber-attacks and intrusions into our computer systems, we do not believe such attacks have had a material adverse effect on our product sales, business and results of operations. While

We also face risks relating to the reporting of pricing data that affects the reimbursement of and discounts provided for our products. In the United States, pricing data that we continuesubmit to investthe U.S. government impacts the payment rates for providers, rebates we pay, and discounts we are required to provide under Medicare, Medicaid and other government drug programs. Government price reporting regulations are complex and may require a manufacturer to update certain previously submitted data. Our price reporting data calculations are reviewed monthly and quarterly, and based on such reviews we have on occasion restated previously reported pricing data to reflect changes in the protectioncalculation methodology, reasonable assumptions and/or underlying data. If our submitted pricing data are incorrect, we may become subject to substantial fines and monitoring of our criticalpenalties or sensitive data and information technology, there can be no assurance that our efforts will prevent service interruptions or detect all breaches to our systems thatother government enforcement actions, which could adversely affecthave a material adverse effect on our business and operations and/orresults of operations. In addition, as a result in the loss of critical or sensitive information, which could result in financial, legal, business or reputational harmrestating previously reported price data, we also may be required to us.pay additional rebates and provide additional discounts.
