AMGEN INC.
NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS
September 30, 2010
(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 medicines company that discovers, develops, manufactures and markets medicines for grievous illnesses. We concentrate on innovating novel medicines based on advances in cellular and molecular biology and we operate in one business segment, human therapeutics.
Basis of presentation
The financial information for the three and nine months ended September 30, 2010 and 2009 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 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, 2009 and our condensed consolidated financial statements in our Quarterly Reports on Form 10-Q for the three months ended March 31, 2010 and for the three months and six months ended June 30, 2010.
Principles of consolidation
The condensed consolidated financial statements include the accounts of Amgen as well as its wholly 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 accounting principles generally accepted in the United States (“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 are recorded at historical cost, net of accumulated depreciation of $5.0 billion and $4.6 billion as of September 30, 2010 and December 31, 2009, respectively.
Fair value measurement
In January 2010, we adopted a newly issued accounting standard which requires additional disclosure about the amounts of and reasons for significant transfers between levels of the fair value hierarchy discussed in Note 8, “Fair value measurement.” This standard also clarifies existing disclosure requirements related to the level of disaggregation of fair value measurements for each class of assets and liabilities and disclosures about inputs and valuation techniques used to measure fair value for both recurring and nonrecurring Level 2 and Level 3 measurements. As this accounting standard only requires enhanced disclosure, the adoption of this standard did not impact our financial position, results of operations or cash flows. In addition, effective for interim and annual periods beginning after December 15, 2010, this standard will require additional disclosure and require an entity to present disaggregated information about activity in Level 3 fair value measurements on a gross basis, rather than a single amount.
2. Income taxes
The effective tax rates for the three and nine months ended September 30, 2010 and September 30, 2009 are different from the statutory rate primarily as a result of indefinitely invested earnings of our foreign operations and the favorable resolution of certain non-routine transfer pricing matters with tax authorities for prior periods. 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.

AMGEN INC.
NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS (Continued)
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 and our income tax returns are routinely audited by the tax authorities in those jurisdictions. Significant disputes can arise with these tax authorities involving the timing and amount of deductions, the use of tax credits and allocations of income among various tax jurisdictions because of differing interpretations of tax laws and regulations. We are no longer subject to U.S. federal income tax examinations for years ending on or before December 31, 2004 or to California state income tax examinations for years ending on or before December 31, 2003.
The Internal Revenue Service (“IRS”) is currently examining our U.S. income tax returns for the years ended December 31, 2007 and 2008. As of September 30, 2010, the Company and the IRS have agreed to certain transfer pricing adjustments for the years ended December 31, 2007 and 2008 and the Company has accordingly adjusted its liability for unrecognized tax benefits (“UTBs”) as discussed below. The remainder of this examination is expected to be completed in 2011.
During the three and nine months ended September 30, 2010, the gross amount of our UTBs increased by approximately $80 million and $225 million, respectively, as a result of tax positions taken during the current year. During the nine months ended September 30, 2010, the gross amount of our UTBs decreased by approximately $375 million due to settlements with tax authorities related to resolution of prior years’ transfer pricing matters. These settlements did not materially impact the effective tax rate. Substantially all of our UTBs as of September 30, 2010, if recognized, would affect our effective tax rate. As of September 30, 2010, the Company believes that it is reasonably possible that our gross liabilities for UTBs may decrease by up to $135 million within the succeeding twelve months due to potential tax settlements.
3. Earnings per share
The computation of basic earnings per share (“EPS”) is based upon the weighted-average number of our common shares outstanding. The computation of diluted EPS is based upon the weighted-average number of our common shares and potential dilutive common shares outstanding. Potential common shares outstanding, determined using the treasury stock method, principally include: stock options, restricted stock units and other equity awards under our employee compensation plans; our 2011 Convertible Notes, 2013 Convertible Notes and 2032 Modified Convertible Notes, as discussed below; and our outstanding warrants (collectively “dilutive securities”). The convertible note hedges purchased in connection with the issuance of our 2011 Convertible Notes and 2013 Convertible Notes are excluded from the calculation of diluted EPS as their impact is always anti-dilutive.
Upon conversion of our 2011 Convertible Notes, 2013 Convertible Notes and 2032 Modified Convertible Notes, the principal amount or accreted value would be settled in cash and the excess of the conversion value, as defined, over the principal amount or accreted value may be settled in cash and/or shares of our common stock. Therefore, only the shares of our common stock potentially issuable with respect to the excess of the notes’ conversion value over their principal amount or accreted value, if any, are considered as dilutive potential common shares for purposes of calculating diluted EPS.
The following table sets forth the computation for basic and diluted EPS (in millions, except per share information):

For both the three and nine months ended September 30, 2010, there were employee stock options, calculated on a weighted average basis, to purchase 44 million shares of our common stock with exercise prices greater than the average market prices of our

common stock for these periods that are not included in the computation of diluted EPS as their impact would have been anti-dilutive. For the three and nine months ended September 30, 2009, there were employee stock options, calculated on a weighted average basis, to purchase 31 million and 43 million shares of our common stock, respectively, with exercise prices greater than the average market prices of our common stock for these periods that are not included in the computation of diluted EPS as their impact would have been anti-dilutive. In addition, shares of our common stock which may be issued upon conversion of our convertible debt or upon exercise of our warrants are not included in the computation of diluted EPS for any of the periods presented above as their impact on diluted EPS would have been anti-dilutive. Shares which may be issued under our 2010 performance award plan were also excluded because conditions under the plan were not met.

For the three months ended September 30, 2010 and 2009, realized gains totaled $34 million and $17 million, respectively, and realized losses totaled $11 million and $8 million, respectively. For the nine months ended September 30, 2010 and 2009, realized gains totaled $92 million and $77 million, respectively, and realized losses totaled $14 million and $56 million, respectively. The cost of securities sold is based on the specific identification method.
The primary objectives of our investment portfolio are liquidity and safety of principal. Investments are made with the objective of achieving the highest rate of return consistent with these two objectives. Our investment policy limits debt security investments to certain types of debt and money market instruments issued by institutions primarily with investment grade credit ratings and places restrictions on maturities and concentration by type and issuer.
We review our available-for-sale investments for other-than-temporary declines in fair value below our cost basis on a quarterly basis and whenever events or changes in circumstances indicate that the cost basis of an asset may not be recoverable. This evaluation is based on a number of factors, including the length of time and extent to which the fair value has been below our cost basis and adverse conditions specifically related to the security, including any changes to the credit rating of the security by a rating agency. As of September 30, 2010 and December 31, 2009, we believe that the cost bases for our available-for-sale investments were recoverable in all material respects.

Debt issuances
In March 2010, we issued $700 million aggregate principal amount of notes due in 2040 (the “2040 Notes”) and $300 million aggregate principal amount of notes due in 2020 (the “March 2020 Notes”) in a registered offering. In September 2010, we issued $900 million aggregate principal amount of notes due in 2020 (the “October 2020 Notes”) and $600 million aggregate principal amount of notes due in 2041 (the “2041 Notes”) in a registered offering. The 2040 Notes, March 2020 Notes, October 2020 Notes and 2041 Notes pay interest at fixed annual rates of 5.75%, 4.50%, 3.45% and 4.95%, respectively. These notes may be redeemed at any time at our option, in whole or in part, at an amount equal to the outstanding principal amount of the notes being redeemed plus accrued interest and a “make-whole” amount, as defined. Upon the occurrence of a change in control triggering event, as defined, we may be required to purchase all or a portion of these notes at a price equal to 101% of the principal amount of the notes plus accrued interest. Debt issuance costs incurred in connection with the issuance of this debt totaled approximately $17 million and are being amortized over the lives of the notes.
2017 Notes
In March 2010, we entered into interest rate swap agreements that effectively convert a fixed-rate interest coupon to a London Interbank Offered Rate (“LIBOR”)-based floating rate coupon over the remaining life of the 2017 notes.

Total
    46.0     $ 2,664       37.5     $ 1,997
 
                     
In December 2009, the Board of Directors authorized us to repurchase up to an additional $5.0 billion of common stock of which a total of $3.3 billion remains available as of September 30, 2010. The manner of purchases, the amount we spend and the number of shares repurchased will vary based on a variety of factors, including the stock price, blackout periods in which we are restricted from repurchasing shares, and our credit rating and may include private block purchases as well as market transactions.
8. Fair value measurement
We use various valuation approaches in determining the fair value of our financial assets and liabilities 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 the 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 the asset or liability and are developed based on the best information available in the circumstances. The fair value hierarchy is broken down into three levels based on the source of inputs as follows:
       
Level 1
   
Valuations based on unadjusted quoted prices in active markets for identical assets or liabilities that the Company has the ability to access
 
       
Level 2
    Valuations for which all significant inputs are observable, either directly or indirectly, other than level 1 inputs
 
       
Level 3
    Valuations 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 to measure 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.

Our U.S. Treasury securities, money market mutual funds and equity securities are valued using quoted market prices in active markets with no valuation adjustment. We value our U.S. Treasury securities and money market mutual funds taking into consideration valuations obtained from a third-party pricing service.
Substantially all of our other government related and corporate debt securities are investment grade with maturity dates of five years or less. Our government related debt securities portfolio is comprised of securities with a weighted average credit rating of “AAA” or equivalent by Standard and Poor’s (“S&P”), Moody’s Investors Services, Inc. (“Moody’s”) or Fitch, Inc. (“Fitch”), and our corporate debt securities portfolio has a weighted average credit rating of “A” or equivalent by S&P, Moody’s or Fitch. We value these securities taking into consideration valuations obtained from third-party pricing services. The pricing services utilize 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. These inputs include reported trades and broker/dealer quotes of the same or similar securities, issuer credit spreads, benchmark securities and other observable inputs.
Our mortgage and asset backed securities portfolio is comprised entirely of senior tranches, with a credit rating of “AAA” or equivalent by S&P, Moody’s or Fitch. We value these securities taking into consideration valuations obtained from third-party pricing services. The pricing services utilize 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. These inputs include reported trades and broker/dealer quotes of the same or similar securities, issuer credit spreads, benchmark securities, prepayment/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.
Substantially all of our foreign currency forward and option contracts have maturities of three years or less and all are entered into with counterparties that have a minimum credit rating of “A-” or equivalent by S&P, Moody’s or Fitch. We value these securities taking into consideration valuations obtained from a third-party valuation service that utilizes an income-based industry standard valuation model for which all significant inputs are observable, either directly or indirectly, to estimate fair value. These inputs include quoted foreign currency spot rates, forward points, LIBOR and swap curves and obligor credit default swap rates. In addition, inputs for our foreign currency option contracts also include implied volatility measures. These inputs, where applicable, are at commonly quoted intervals. As of September 30, 2010 and December 31, 2009, we had open foreign currency forward contracts with notional amounts of $3.2 billion and $3.4 billion, respectively, and open option contracts with notional amounts of $370 million and $376 million, respectively, that were primarily Euro-based and were designated as cash flow hedges. In addition, as of September 30, 2010 and December 31, 2009, we had $609 million and $414 million, respectively, of foreign currency forward contracts to reduce exposure to fluctuations in value of certain assets and liabilities denominated in foreign currencies that were primarily Euro-based and that were not designated as hedges (see Note 9, “Derivative instruments").
Our interest rate swap contracts are entered into with counterparties that have a minimum credit rating of “A-” or equivalent by S&P, Moody’s or Fitch. We value these contracts using an income-based industry standard valuation model for which all significant inputs are observable either directly or indirectly to estimate fair value. These inputs include LIBOR and swap curves and obligor credit default swap rates. We had interest rate swap agreements with an aggregate notional amount of $2.6 billion and $1.5 billion as of September 30, 2010 and December 31, 2009, respectively, that were designated as fair value hedges (see Note 9, “Derivative instruments”).
There have been no transfers of assets or liabilities between the fair value measurement levels and there were no material remeasurements to fair value during the nine months ended September 30, 2010 and 2009 of assets and liabilities that are not measured at fair value on a recurring basis.

Borrowings
We value our convertible and modified convertible notes using an income-based industry standard valuation model for which all significant inputs are observable either directly or indirectly, including benchmark yields adjusted for our credit risk, to estimate fair value (Level 2). The fair values of our convertible notes and modified convertible notes exclude their equity components and represent only the liability components of these instruments as their equity components are included in “Common stock and additional paid-in capital” in the Condensed Consolidated Balance Sheets. We value our other long-term notes 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, to estimate fair value. These inputs include reported trades and broker/dealer quotes of the same or similar securities, credit spreads, benchmark yields and other observable inputs (Level 2).

9. Derivative instruments
The Company is exposed to risks related to its business operations, certain of which are managed through derivative instruments. The risks that we manage by using derivative instruments are foreign exchange rate risk and interest rate risk. We use financial instruments including foreign currency forward, foreign currency option, forward interest rate and interest rate swap contracts to reduce our risk to these exposures. We do not use derivatives for speculative trading purposes.
We recognize all of our derivative instruments as either assets or liabilities at fair value in the Condensed Consolidated Balance Sheets (see Note 8, “Fair value measurement”). The accounting for changes in the fair value of a derivative instrument depends on whether it has been formally designated and qualifies as part of a hedging relationship under the applicable accounting standards and, further, on the type of hedging relationship. For derivatives formally designated as hedges, we assess both at inception and quarterly thereafter, whether the hedging derivatives are highly effective in offsetting changes in either the fair value or cash flows of the hedged item. Our derivatives that are not designated and do not qualify as hedges are adjusted to fair value through current earnings.
Cash flow hedges
We are exposed to possible changes in values of certain anticipated foreign currency cash flows resulting from changes in foreign currency exchange rates, primarily associated with our international product sales denominated in Euros. Increases or decreases in the cash flows associated with our international product sales due to movements in foreign currency exchange rates are partially offset by the corresponding increases and decreases in our international operating expenses resulting from these foreign currency exchange rate movements. To further reduce our exposure to foreign currency exchange rate fluctuations on 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 successive periods. As of September 30, 2010 and December 31, 2009, we had open foreign currency forward contracts with notional amounts of $3.2 billion and $3.4 billion,

NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS (Continued)
respectively, and open option contracts with notional amounts of $370 million and $376 million, respectively. These foreign currency forward and option contracts, primarily Euro-based, have been designated as cash flow hedges, and accordingly, the effective portion of the unrealized gains and losses on these contracts are reported in Accumulated Other Comprehensive Income (“AOCI”) in the Condensed Consolidated Balance Sheets and reclassified to earnings in the same periods during which the hedged transactions affect earnings.
In connection with the anticipated issuance of long-term fixed-rate debt, we occasionally enter into forward interest rate contracts in order to hedge the variability in cash flows due to changes in the applicable Treasury rate between the time we enter into these contracts and the time the related debt is issued. Gains and losses on such contracts, which are designated as cash flow hedges, are recorded in Other Comprehensive Income (“OCI”) and amortized into earnings over the lives of the associated debt issuances.
The following table reflects the effective portion of the unrealized gain/(loss) recognized in OCI for our cash flow hedge contracts (in millions):

Total
      $ 30     $ (9 )   $ 45     $ 20  
 
                           
No portions of our cash flow hedge contracts are excluded from the assessment of hedge effectiveness and the ineffective portions of these hedging instruments resulted in approximately $1 million of expense recorded in “Interest and other income, net” in the Condensed Consolidated Statements of Income for both the three and nine months ended September 30, 2010. The ineffective portions of these hedging instruments resulted in an aggregate expense of approximately $1 million recorded in “Interest and other income, net” and “Interest expense, net” in the Condensed Consolidated Statements of Income for both the three and nine months ended September 30, 2009. As of September 30, 2010, the amounts expected to be reclassified from AOCI into earnings over the next 12 months are approximately $8 million of losses on foreign currency forward and option contracts and approximately $1 million of losses on forward interest rate contracts.
Fair value hedges
To achieve a desired mix of fixed and floating interest rate debt, we have entered into interest rate swap agreements, which qualify and have been designated as fair value hedges. The terms of these interest rate swap agreements correspond to the related hedged debt instruments and effectively convert a fixed interest rate coupon to a LIBOR-based floating rate coupon over the lives of the respective notes. We had interest rate swap agreements with aggregate notional amounts of $2.6 billion and $1.5 billion as of September 30, 2010 and December 31, 2009, respectively. The interest rate swap agreements as of September 30, 2010 were for our notes due in 2014, 2017 and 2018 and, as of December 31, 2009 for our notes due in 2014 and 2018. For derivative instruments that are designated and qualify as a fair value hedge, the unrealized gain or loss on the derivative resulting from the change in fair value during the period as well as the offsetting unrealized loss or gain of the hedged item resulting from the change in fair value during the period attributable to the hedged risk are recognized in current earnings. For the three and nine months ended September 30, 2010, we included the unrealized losses on the hedged debt of $76 million and $200 million, respectively, in the same line item, “Interest expense, net” in the Condensed Consolidated Statements of Income, as the offsetting unrealized gains of $76 million and $200 million, respectively, on the related interest rate swap agreements. For the three and nine months ended September 30, 2009, we included the unrealized loss on the hedged debt of $22 million and the unrealized gain on the hedged debt of $81 million, respectively, in the same line item, “Interest expense, net” in the Condensed Consolidated Statements of Income, as the offsetting unrealized gain of $22 million and the unrealized loss of $81 million, respectively, on the related interest rate swap agreements.

We enter into foreign currency forward contracts to reduce our exposure to foreign currency fluctuations of certain assets and liabilities denominated in foreign currencies which are not designated as hedging transactions. These exposures are hedged on a month-to-month basis. As of September 30, 2010 and December 31, 2009, the total notional amounts of these foreign currency forward contracts, primarily Euro-based, were $609 million and $414 million, respectively.

Our derivative contracts that were in a liability position as of September 30, 2010 contain certain credit risk related contingent provisions that are triggered if (i) we were to undergo a change in control and (ii) our or the surviving entity’s creditworthiness deteriorates, which is generally defined as having either a credit rating that is below investment grade or a materially weaker creditworthiness after the change in control. If these events were to occur, the counterparties would have the right, but not the obligation, to close the contracts under early termination provisions. In such circumstances, the counterparties could request immediate settlement of these contracts for amounts that approximate the then current fair values of the contracts.
10. Contingencies and commitments
In the ordinary course of business, we are involved in various legal proceedings and other matters, including those discussed in this Note, which are complex in nature and have outcomes that are difficult to predict. We record accruals for such contingencies to the extent that we conclude that it is probable that a liability will be incurred and the amount of the related loss can be reasonably estimated. While it is not possible to accurately predict or determine the eventual outcome of these items, one or more of these items currently pending could have a material adverse effect on our consolidated results of operations, financial position or cash flows.
Certain of our legal proceedings and other matters are discussed below:
Teva Pharmaceuticals USA, Inc. and Teva Pharmaceutical Industries Ltd. (“Teva”) Matters
Sensipar® Abbreviated New Drug Application Litigation
On September 30, 2010, the U.S. District Court for the District of Delaware issued a scheduling order setting a trial date for November 30, 2010.
Teva v. Amgen, the ‘603 Patent Litigation
On August 23, 2010, the parties filed a stipulated scheduling order setting forth certain dates for discovery, expert discovery and a claim construction hearing.

Birch v. Sharer, et al.
On September 29, 2010 Judge Highberger in the Complex Division of Los Angeles Superior Court denied the individual defendants’ demurrers finding that the plaintiff had adequately pled (but not proved) wrongful refusal. Amgen and the individual defendants filed answers on October 29, 2010. A case management conference is scheduled for November 12, 2010.
Third-Party Payers Litigation
On October 8, 2010, oral argument was heard before the U.S. Court of Appeals for the Ninth Circuit (the “9th Circuit”) and on October 21, 2010, the 9th Circuit affirmed the U.S. District Court of the Central District of California’s decision dismissing the action with prejudice.
Qui Tam Actions
On September 20, 2010, the U.S. District Court for the District of Massachusetts (the “Massachusetts District Court”) entered the written ruling denying Amgen’s motions to dismiss. On October 22, 2010, the states of New York, Massachusetts, Michigan, California, Illinois and Indiana, on behalf of the states of Georgia and New Mexico, and the relator filed opening briefs with the U.S. Court of Appeals for the First Circuit. The Massachusetts District Court has set a trial date for July 2011.
Warren General Hospital v. Amgen
Amgen’s motion to dismiss was granted by the U.S. District Court for the District of New Jersey on June 7, 2010 and plaintiffs filed their notice of appeal to the motion to dismiss on June 14, 2010 with the U.S. Court of Appeals for the Third Circuit (the “3rd Circuit”). Plaintiff filed their opening brief on August 23, 2010 and Amgen’s response brief was filed on September 22, 2010. Plaintiff filed its reply brief on October 6, 2010. No hearing date for the appellate argument before the 3rd Circuit has been set.
Other
On August 20, 2010, Amgen received a stockholder demand on the Board of Directors (“Board”) to take action to remedy alleged breaches of fiduciary duty and related violations by the Board and certain officers of the Company. The stockholder alleged that the directors and certain executive officers caused the Company to issue false or misleading statements regarding the safety of EPOGEN® and Aranesp® and promotional practices regarding these drugs. The Board undertook an investigation into the allegations made by the stockholder and on October 11, 2010, the Board notified the stockholder that it had rejected the stockholder’s demand.

Overview
The following Management’s Discussion and Analysis of Financial Condition and Results of Operations (“MD&A”) is intended to assist the reader in understanding Amgen’s business. MD&A is provided as a supplement to, and should be read in conjunction with, our Annual Report on Form 10-K for the year ended December 31, 2009 and our Quarterly Reports on Form 10-Q for the periods ended March 31, 2010 and June 30, 2010. Our results of operations discussed in MD&A are presented in conformity with GAAP.
We are the largest independent biotechnology medicines company. We discover, develop, manufacture and market medicines for grievous illnesses. We concentrate on innovating novel medicines based on advances in cellular and molecular biology. Our mission is to serve patients. We operate in one business segment: human therapeutics. Therefore, our results of operations are discussed on a consolidated basis.
Currently, we market primarily recombinant protein therapeutic products for supportive cancer care, nephrology and inflammation. Our principal products currently include Aranesp® (darbepoetin alfa), EPOGEN® (Epoetin alfa), Neulasta® (pegfilgrastim), NEUPOGEN® (Filgrastim) and ENBREL (etanercept), all of which are sold in the United States. ENBREL is marketed under a co-promotion agreement with Pfizer Inc. (“Pfizer”) in the United States and Canada. Our international product sales consist principally of European sales of Aranesp®, Neulasta® and NEUPOGEN®. For both the three and nine months ended September 30, 2010, our principal products represented 92% of worldwide product sales; for both the three and nine months ended September 30, 2009, our principal products represented 93% of worldwide product sales.
During the three months ended June 30, 2010, we also began selling Prolia (denosumab). We are jointly commercializing Prolia with GlaxoSmithKline plc (“GSK”) for postmenopausal osteoporosis (“PMO”) in Europe in accordance with a collaboration agreement entered into in July 2009. In addition, our other marketed products include: Sensipar®/Mimpara® (cinacalcet); Vectibix® (panitumumab); and Nplate® (romiplostim). For additional information about our products, their approved indications and where they are marketed, see “Item 1. Business – Marketed Products and Selected Product Candidates” in Part I of our Annual Report on Form 10-K for the year ended December 31, 2009 and the discussion below with respect to Prolia.
Key developments
The following is a list of selected key developments that occurred during 2010 affecting our business. For additional 2010 developments and a more comprehensive discussion of certain developments discussed below, see our Quarterly Reports on Form 10-Q for the periods ended March 31, 2010 and June 30, 2010.

Prolia Developments
On May 28, 2010, the European Commission (“EC”) granted marketing authorization for Prolia for the treatment of osteoporosis in postmenopausal women at increased risk of fractures and for the treatment of bone loss associated with hormone ablation in men with prostate cancer at increased risk of fractures. The timing of reimbursement authority approval of pricing in individual European Union countries will vary by country, which could follow the EC approval by many months. For example, on July 1, 2010, Proliareceived reimbursement authority in Germany, and on October 27, 2010, the National Institute for Health and Clinical Excellence in the United Kingdom recommended Prolia for reimbursement as a treatment option for certain postmenopausal women who are at increased risk of primary and secondary osteoporotic fractures if other treatments available on the publicly-funded National Health Service are unsuitable.
On June 1, 2010, the FDA approved Prolia for the treatment of postmenopausal women with osteoporosis at high risk for fracture, defined as a history of osteoporotic fracture, or multiple risk factors for fracture, or patients who have failed or are intolerant to other available osteoporosis therapy.
We estimate that the majority of potential U.S. Prolia patients are covered under Medicare and the remaining under commercial plans. Prolia is currently being reimbursed under Medicare Part B through a “buy and bill” process. The buy and bill reimbursement process for Prolia may require time to establish as it involves physicians purchasing Prolia with the intent to submit a claim to a payer for reimbursement after the injection has been administered. As of September 30, 2010, all 15 Medicare Administration Contractors have confirmed medical coverage for Prolia and have issued paid claims. Future U.S. product sales for Prolia will be in part dependent upon physicians’ willingness to use a buy and bill approach, in particular primary care physicians who most frequently administer Prolia to patients but are less accustomed to this reimbursement process. In addition, U.S. product sales for Prolia will be supported by Medicare Part D coverage, which we expect will be obtained in 2011, and by the expansion of commercial coverage.
Worldwide sales of Prolia for the three and nine months ended September 30, 2010 totaled approximately $10 million and $13 million, respectively.
Please refer to our Quarterly Report on Form 10-Q for the period ended June 30, 2010 for additional details on the Prolia risk evaluation and mitigation strategy (“REMS”) program and the post-marketing surveillance program for PMO patients.
Other Denosumab Developments
On May 14, 2010, we submitted a Biologics License Application (“BLA”) to the FDA for denosumab for the reduction of skeletal related events (“SREs”) in cancer patients. On July 16, 2010, we announced that the FDA granted priority review designation to our denosumab BLA. Consistent with priority review guidelines, the FDA will target an Agency action within six months of the application submission date, resulting in a Prescription Drug User Fee Act action date of November 18, 2010. We also submitted a marketing authorization application to the European Medicines Agency (“EMA”) on June 4, 2010 for denosumab for the reduction of SREs in cancer patients.
ESA Developments
On February 16, 2010, Amgen and Centocor Ortho Biotech Products, L.P., a subsidiary of Johnson & Johnson (“J&J”), announced that the FDA approved a REMS for erythropoiesis-stimulating agents (“ESAs”) which includes Aranesp®, EPOGEN® and Procrit® (Epoetin alfa). In order to ensure continued access to ESAs for healthcare providers who prescribe, or prescribe and dispense, ESAs to patients with cancer, healthcare providers and hospitals are required to train and enroll in the ESA APPRISE (Assisting Providers and cancer Patients with Risk Information for the Safe use of ESAs) Oncology Program by February 15, 2011. Enrolled prescribers are required to document that a discussion about the risks of ESAs took place with each patient prior to the initiation of each new course of ESA therapy. Direct patient registration or approval prior to ESA administration is not required through the ESA APPRISE Oncology Program.
On July 26, 2010, the Centers for Medicare & Medicaid Services (“CMS”) released the Final Rule on Bundling in Dialysis, effective January 1, 2011. Under the final rule, end stage renal disease (“ESRD”) facilities were required to elect, by November 1, 2010, whether they would implement the rule in its entirety beginning in 2011 or ratably over a four-year period beginning in 2011. On November 2 and November 4, 2010, Fresenius Medical Care and DaVita Inc., the two largest dialysis organizations in the United States, separately announced that they intend to implement the final bundling rule in its entirety beginning in 2011 for all of their clinics. In preparation of implementing the final rule, ESRD facilities may transition their treatment protocols in the later part of 2010, which could also impact the dose/utilization of EPOGEN®.
On October 18, 2010, the FDA held a Cardiovascular and Renal Drugs Advisory Committee (“CRDAC”) meeting to review results from the Trial to Reduce Cardiovascular Events with Aranesp® Therapy (“TREAT”) study conducted in patients not on dialysis, and how those results inform the appropriate use of ESAs in patients with chronic kidney disease (“CKD”). Prior to the CRDAC meeting, we submitted proposed labeling changes to the FDA regarding the use of ESAs in chronic renal failure patients not on dialysis that would limit treatment to patients who are most likely to benefit, specifically those with significant anemia (<10 grams per deciliter (“g/dL”)), and who are at high risk for transfusion and for whom transfusion avoidance is considered clinically important, including those in whom it is important to preserve kidney transplant eligibility. In addition to

18

narrowing the patient population, we are proposing a more conservative dosing algorithm in these patients. The Company will continue working with the FDA to develop information that will optimize the use of ESAs in CKD patients. In addition, on October 26, 2010, the CMS announced a January 19, 2011 meeting of the Medicare Evidence Development & Coverage Advisory Committee (“MEDCAC”) to further examine currently available evidence on the use of ESAs to manage anemia in patients who have CKD.
Certain of these ESA developments could have material adverse impacts on our business and results of operations.
Please refer to our Quarterly Reports on Form 10-Q for the periods ended March 31, 2010 and June 30, 2010 for additional details on ESA developments.
U.S. Healthcare Reform
In March 2010, the Patient Protection and Affordable Care Act and the companion Healthcare and Education Reconciliation Act were signed into law. We refer to these two laws collectively as the “new healthcare reform law.” The new healthcare reform law imposes additional costs on and reduces the revenues of companies in the biotechnology and pharmaceutical industries. The following table summarizes certain provisions of the new healthcare reform law and the adverse impacts of these provisions on our U.S. product sales to date.
               
            Nine months ended
            September 30, 2010
Healthcare Reform Provision   Effective Date   (in millions)
 
             
    Medicaid base rebate rate payable on our products increased from 15.1% to 23.1% of the Average Manufacturer’s Price (“AMP”)
  January 1, 2010     $ 46
    Public Health Service (“PHS”) (340B) program eligibility expanded
         
–   Discounts comparable to the Medicaid rebate extended to entities receiving PHS grants and to hospitals serving a disproportionate number of Medicare and Medicaid patients
  January 1, 2010       17
    Medicaid rebates applied to managed care organizations
  March 23, 2010       70
    AMP Definition changed which may result in higher discounts for certain of our products
  October 1, 2010      
    Prescription Drug Manufacturers’ Annual Fee
             
–   Aggregate annual fee to be paid by manufacturers and importers of branded prescription drugs totaling $28 billion over 10 years, of which $2.5 billion is payable in 2011
             
–   Fee to be apportioned among participating companies based on each company’s sales of qualifying products. The fee is not deductible for U.S. federal income tax purposes
  January 1, 2011      
    Part D mandatory discount (referred to as the “doughnut hole”)
         
–   50% discount to Medicare Part D patients whose prescription expenses exceed the Part D limit, but have not reached the catastrophic coverage threshold
  January 1, 2011        
    Medicaid coverage eligibility expanded from 100% to 133% of the federal poverty level
  January 1, 2014      
 
             
 
  Total     $ 133
 
             
Total U.S. product sales for the three months ended September 30, 2010 were adversely impacted by $64 million by the new healthcare reform law provisions that were in effect during this period.
We anticipate that the impact of the above provisions for the full year 2010 will be slightly below $200 million and that the full year impact for 2011 will be approximately two to two-and-a-half times the amount currently estimated for 2010. Estimation of the aggregate financial impact resulting from the new healthcare reform law is highly complex and depends on a number of factors. Therefore, our estimates are subject to change.
The new healthcare reform law authorizes the FDA to approve biosimilar products. With the resulting likely introduction of biosimilars in the United States, we may face greater competition from biosimilar products,

including from biosimilar manufacturers with approved products in Europe that may seek to quickly obtain U.S. approval now that biosimilar legislation has been enacted, subject to our ability to enforce our patents.
Please refer to our Quarterly Reports on Form 10-Q for the periods ended March 31, 2010 and June 30, 2010 for additional details on the new healthcare reform law.
Vectibix® Developments
On April 16, 2010, our application for marketing authorization for the use of Vectibix® in first- and second-line treatment of metastatic colorectal cancer (“mCRC”) in patients whose tumors contain wild type KRAS genes was submitted to the EMA. We filed supplemental BLA submissions for first- and second-line mCRC with the FDA on October 29 and November 4, 2010.
On August 11, 2010, we announced top-line results from a 658-patient randomized phase 3 trial evaluating Vectibix® as a first-line treatment in patients with recurrent and/or metastatic squamous cell head and neck cancer. The data showed the addition of Vectibix® to platinum-based chemotherapy did not result in a statistically significant improvement in overall survival, the primary endpoint, compared to chemotherapy alone [median 11.1 months versus 9.0 months, hazard ratio (“HR”) 0.87 (95% confidence interval (“CI”): 0.73, 1.05)]. Therefore, the study did not meet its primary endpoint. Secondary endpoints of progression-free survival (“PFS”) [median 5.8 months versus 4.6 months, HR 0.78 (95% CI: 0.66, 0.92)] and objective response rate (36% versus 25%) were numerically improved but were not tested for statistical significance. The secondary endpoints included PFS, objective response rate, duration of response, time to progression, time to response, patient reported outcomes and safety. The most frequently reported adverse events in the Vectibix® plus chemotherapy arm included nausea, rash, neutropenia and vomiting, as anticipated, for this combination therapy.
Puerto Rico Tax Legislation
On October 25, 2010, the government of Puerto Rico passed legislation that established a new tax on the sale of products manufactured in Puerto Rico, effective January 1, 2011. We are currently evaluating the new legislation and its potential impact on Amgen.

The following discusses certain key changes in our results of operations for the three and nine months ended September 30, 2010 as well as our financial condition as of September 30, 2010.
The increase in total revenues for the nine months ended September 30, 2010 was primarily due to increases in worldwide product sales, discussed below, and, to a lesser extent, other revenues resulting from certain milestone payments earned in 2010.
U.S. product sales for the three months ended September 30, 2010 were largely unchanged as the decline in Aranesp® sales was substantially offset by an increase in Neulasta®/NEUPOGEN® sales. The increase in U.S. product sales for the nine months ended September 30, 2010 was primarily due to favorable changes in wholesaler inventories.
Excluding a $16 million unfavorable and a $34 million favorable foreign exchange impact, international product sales increased 4% and 5% for the three and nine months ended September 30, 2010, respectively, primarily due to increases in demand for Sensipar®, Vectibix®, Nplate® and Prolia.
The increase in operating expenses for the three months ended September 30, 2010 was primarily driven by lower research and development (“R&D”) costs principally due to higher cost recoveries in 2009. The increase in operating expenses for the nine months ended September 30, 2010 was primarily due to increased selling, general and administrative (“SG&A”) expenses in part due to increased spending activities for Prolia.
The decrease in net income for the three months ended September 30, 2010 was primarily due to lower operating income and a higher effective income tax rate as a result of favorable tax settlements in 2009. The decrease in net income for the nine months ended September 30, 2010 was primarily due to a higher effective income tax rate as a result of favorable tax settlements in 2009, partially offset by higher operating income.
The decrease in diluted EPS for the three months ended September 30, 2010 was due to the reduction in net income, partially offset by a reduction in the number of shares used in the calculation of diluted EPS. The increase in diluted EPS for the nine months ended September 30, 2010 was due to the reduction in the number of shares used in the calculation of diluted EPS, partially offset by the reduction in net income. The decreases in the number of shares used in the computations of diluted EPS reflect the impact of our stock repurchase program, including approximately 6.6 million and 46 million shares that were repurchased in the three and nine months ended September 30, 2010 at total costs of $364 million and $2.7 billion, respectively.
As of September 30, 2010, our cash, cash equivalents and marketable securities totaled $17.0 billion and total debt outstanding was $13.3 billion, including $2.5 billion which is due in February 2011. Of our total cash, cash equivalents and

21


Table of Contents

marketable securities balances as of September 30, 2010, approximately $14.0 billion was generated from operations in foreign tax jurisdictions and is intended for permanent use in our foreign operations. If these funds were repatriated for use in our U.S. operations, we would be required to pay additional U.S. federal and state income taxes at the applicable marginal tax rates.

Product sales are influenced by a number of factors, some of which may impact sales of certain products more significantly than others. For a list of certain of these factors, see “Results of Operations – Product Sales” in our Quarterly Report on Form 10-Q for the period ended June 30, 2010.
Aranesp®
Total Aranesp® sales by geographic region were as follows (dollar amounts in millions):
                                                 
    Three months ended September 30,   Nine months ended September 30,
    2010     2009     Change   2010     2009     Change
Aranesp® — U.S.
  $ 283     $ 333       (15 )%   $ 818     $ 963       (15 )%
Aranesp® — International
    340       352       (3 )%     1,035       1,041       (1 )%

The decrease in U.S. Aranesp® sales for the three months ended September 30, 2010 was primarily due to a low double-digit percentage point decline in unit demand, reflecting an overall decline in the segment, slightly offset by an increase in the average net sales price, and unfavorable changes in wholesaler inventories. The decrease in U.S. Aranesp® sales for the nine months ended September 30, 2010 was primarily due to a decline in unit demand, reflecting an overall decline in the segment.
Excluding a $7 million unfavorable and a $12 million favorable foreign exchange impact, international Aranesp® sales decreased 1% and 2% for the three and nine months ended September 30, 2010, respectively, primarily due to decreases in demand, reflecting overall declines in the segment.
Future Aranesp® sales will depend, in part, on the factors as set forth in our Quarterly Report on Form 10-Q for the period ended June 30, 2010 and such factors as:
   Regulatory developments, including those resulting from:
–   The October 18, 2010 CRDAC meeting;
–   The proposed ESA product label changes we submitted to the FDA prior to the CRDAC meeting; and
   Reimbursement developments resulting from the January 19, 2011 MEDCAC meeting.
Certain of these factors could have material adverse impacts on future sales of Aranesp®.

EPOGEN®
Total EPOGEN® sales were as follows (dollar amounts in millions):

EPOGEN® — U.S.
  $ 653     $ 663       (2 )%   $ 1,933     $ 1,866       4  %
The decrease in EPOGEN® sales for the three months ended September 30, 2010 was primarily due to low single-digit percentage point declines in both unit demand and the average net sales price, partially offset by favorable changes in wholesaler inventories. The decrease in unit demand reflects a decrease in dose utilization, partially offset by patient population growth. The increase in EPOGEN® sales for the nine months ended September 30, 2010 was primarily due to an increase in unit demand and favorable changes in wholesaler inventories. The increase in unit demand was due to patient population growth, partially offset by a decline in dose utilization.
Future EPOGEN® sales will depend, in part, on the factors as set forth in our Quarterly Report on Form 10-Q for the period ended June 30, 2010 and such factors as:
   Reimbursement developments, including those resulting from:
–   The CMS’s Final Rule on Bundling in Dialysis;
–   The January 19, 2011 MEDCAC meeting;
   Regulatory developments, including those resulting from:
–   The October 18, 2010 CRDAC meeting; and
–   The proposed ESA product label changes we submitted to the FDA prior to the CRDAC meeting.
Certain of these factors could have material adverse impacts on future sales of EPOGEN®.

The increases in U.S. sales of Neulasta®/NEUPOGEN® for the three and nine months ended September 30, 2010 were primarily due to increases in the average net sales price and, for the nine months ended September 30, 2010, favorable changes in wholesaler inventories.
Excluding a $6 million unfavorable and a $15 million favorable foreign exchange impact, international Neulasta®/NEUPOGEN® sales increased 2% and 3% for the three and nine months ended September 30, 2010, respectively, primarily due to increases in demand, reflecting the continued conversion from NEUPOGEN® to Neulasta®.
Future Neulasta®/NEUPOGEN® sales will depend, in part, on the factors as set forth in our Quarterly Report on Form 10-Q for the period ended June 30, 2010.

The decline in ENBREL sales for the three months ended September 30, 2010 was due to share declines, primarily in dermatology, partially offset by a slight increase in the average net sales price. The increase in ENBREL sales for the nine months ended September 30, 2010 was primarily due to favorable changes in wholesaler inventories, as the share declines, primarily in dermatology, were substantially offset by a low single-digit percentage point increase in the average net sales price. ENBREL continues to maintain a leading position in both the rheumatology and dermatology segments.
Future ENBREL sales will depend, in part, on the factors as set forth in our Quarterly Report on Form 10-Q for the period ended June 30, 2010.

Cost of sales
Cost of sales, which excludes the amortization of certain acquired intangible assets, increased to 15.6% and 15.1% of product sales for the three and nine months ended September 30, 2010, respectively, primarily driven by higher inventory write-offs due to product recalls of EPOGEN® and Procrit® and by higher bulk material costs, partially offset by lower excess capacity charges.
Research and development
The increase in R&D expenses for the three months ended September 30, 2010 was principally attributable to $40 million of higher expense recoveries in 2009 associated with ongoing collaborations and higher staff-related costs of $23 million, primarily from increased headcount outside the United States.
The increase in R&D expenses for the nine months ended September 30, 2010 was primarily driven by $101 million of higher expense recoveries in 2009 associated with ongoing collaborations and higher staff-related costs of $72 million, partially offset by lower denosumab SRE clinical trial costs of $64 million and a prior year payment of $50 million to obtain an exclusive license to Cytokinetics Incorporated’s cardiac contractility program.
Selling, general and administrative
The increase in SG&A expenses for the three months ended September 30, 2010 was primarily due to higher costs of $37 million for staff and promotional activities for Prolia and other marketed products and higher litigation expenses of $16 million.
The increase in SG&A expenses for the nine months ended September 30, 2010 was primarily due to higher costs of $126 million for promotional activities for Prolia and other marketed products, higher litigation expenses of $49 million, higher staff-related costs of $36 million and higher expenses associated with the Pfizer profit share of $10 million, partially offset by charges of $23 million in 2009 for certain cost savings initiatives related to our 2007 restructuring plan and by expense recoveries of $21 million related to our GSK collaboration for Prolia.
For the three and nine months ended September 30, 2010 and 2009, excluding expenses associated with the Pfizer profit share of $302 million and $865 million, respectively, and $306 million and $855 million, respectively, SG&A expenses increased 5% and 10%, respectively.

Effective tax rate
    13.8  %     10.0  %     16.5  %     11.0  %
Interest expense, net
Included in interest expense, net for the three and nine months ended September 30, 2010 and 2009 is the impact of non-cash interest expense of $67 million and $198 million, respectively, and of $63 million and $186 million, respectively, resulting from the change in the accounting for our convertible debt effective January 1, 2009.
Interest and other income, net
The increases in interest and other income, net for the three and nine months ended September 30, 2010 were primarily due to higher net realized gains on investments of $14 million and $57 million, respectively, and higher interest income of $13 million and $39 million, respectively, primarily due to higher average cash, cash equivalents and marketable securities balances.
Income taxes
The increases in our effective tax rates for the three and nine months ended September 30, 2010 were primarily due to: (i) the favorable resolution of certain prior years’ non-routine transfer pricing matters with tax authorities during the three and nine months ended September 30, 2009 compared to September 30, 2010; (ii) the exclusion of the benefit of the federal research and experimentation (“R&E”) tax credit in the three and nine months ended September 30, 2010 (the federal R&E credit expired as of December 31, 2009 and was not reinstated as of September 30, 2010); and (iii) a benefit in the three months ended March 31, 2009 relating to adjustments to previously established deferred taxes due to changes in California tax law effective for future periods.

Stockholders’ equity
    24,071       22,667
We believe that existing funds, cash generated from operations and existing sources of and access to financing are adequate to satisfy our working capital, capital expenditure and debt service requirements for the foreseeable future, including the repayment of our 2011 Convertible Notes with a principal balance of $2.5 billion in February 2011. In addition, we plan to opportunistically pursue our stock repurchase program and other business initiatives, 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, sale of marketable securities, borrowings through commercial paper and/or our syndicated credit facility and access to other debt markets and equity markets.
Certain of our financing arrangements contain non-financial covenants and we were in compliance with all applicable covenants as of September 30, 2010. None of our financing arrangements contain any financial covenants.
Cash flows
The following table summarizes our cash flow activity (in millions):
               
    Nine months ended September 30,
    2010     2009
Net cash provided by operating activities
  $ 3,779     $ 4,513
Net cash used in investing activities
    (3,661 )     (2,863 )
Net cash (used in) provided by financing activities
    (51 )     153
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 nine months ended September 30, 2010 decreased primarily due to the timing and amounts of payments to taxing authorities.
Investing
During the nine months ended September 30, 2010 and 2009, cash used in investing activities was primarily for net purchases of $3.2 billion and $2.5 billion, respectively, of marketable securities. Capital expenditures during the nine months ended September 30, 2010 and 2009 totaled $398 million and $386 million, respectively. Capital expenditures during the nine months ended September 30, 2010 and 2009 were primarily associated with manufacturing capacity expansions in Puerto Rico and other site developments. We currently estimate 2010 spending on capital projects and equipment to be approximately $600 million.
Financing
In March 2010, we issued $700 million aggregate principal amount of notes due in 2040 (the “2040 Notes”) and $300 million aggregate principal amount of notes due in 2020 (the “March 2020 Notes”) in a registered offering. In September 2010, we issued $900 million aggregate principal amount of notes due in 2020 (the “October 2020 Notes”) and $600 million aggregate principal amount of notes due in 2041 (the “2041 Notes”) in a registered offering. The 2040 Notes, March 2020 Notes, October 2020 Notes and 2041 Notes pay interest at fixed annual rates of 5.75%, 4.50%, 3.45% and 4.95%, respectively. The notes may be redeemed at any time at our option, in whole or in part, at amounts equal to the outstanding principal amounts of the notes being redeemed plus accrued interest and “make-whole” amounts, as defined. Upon the occurrence of a change in control triggering event, as defined, we may be required to purchase all or a portion of the notes at prices equal to 101% of the principal amounts of the notes plus accrued interest.

See Note 6, “Financing arrangements” to the Condensed Consolidated Financial Statements for a further discussion of our long-term borrowings.
During the nine months ended September 30, 2010, we repurchased 46 million shares of our common stock at a total cost of $2.7 billion ($2.6 billion of which represents a net cash outflow in the period). During the nine months ended September 30, 2009, we repurchased 37.5 million shares of our common stock at a total cost of $2.0 billion. As of September 30, 2010, we had $3.3 billion available for stock repurchases as authorized by our Board of Directors. Repurchases under our stock repurchase program reflects, in part, our confidence in the long-term value of our common stock. Additionally, we believe that it is an effective way of returning cash to our stockholders. The manner of purchases, amount we spend and the number of shares repurchased will vary based on a number of factors including the stock price, blackout periods in which we are restricted from repurchasing shares and our credit rating and may include private block purchases as well as market transactions.
We receive cash from the exercise of employee stock options and from proceeds from the sale of stock under our employee stock purchase program. Our equity award programs provided $62 million and $146 million of cash during the nine months ended September 30, 2010 and 2009, respectively. Proceeds from the exercise of employee stock options will vary from period to period based on, among other factors, fluctuations in the market value of our stock relative to the exercise prices of such options.

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 September 30, 2010.
Management determined that, as of September 30, 2010, 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.

PART II — OTHER INFORMATION
Item 1.   LEGAL PROCEEDINGS
See Note 10, “Contingencies and commitments” to the condensed consolidated financial statements included in our Quarterly Reports on Form 10-Q for the periods ended September 30, 2010, June 30, 2010 and March 31, 2010 for discussions which are limited to certain recent developments concerning our legal proceedings. These discussions should be read in conjunction with Note 20, “Contingencies and commitments” to our consolidated financial statements in Part IV of our Annual Report on Form 10-K for the year ended December 31, 2009.
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 or others on our behalf, our beliefs and our management’s assumptions. These statements are not guarantees of future performance and involve certain risks, uncertainties and assumptions that are difficult to predict. You should carefully consider the risks and uncertainties facing our business. We have described the primary risks relating to our business in our Annual Report on Form 10-K for the fiscal year ended December 31, 2009 and periodically update those risks for material developments. These risks are not the only ones facing us. 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 also may impair our business, operations, liquidity and stock price materially and adversely.
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, of our Annual Report on Form 10-K for the fiscal year ended December 31, 2009 and in our Quarterly Reports on Form 10-Q for the periods ended March 31, 2010 and June 30, 2010, provide additional disclosure and context for these supplemental risks for the third quarter 2010 and are incorporated herein by reference.
Our current products and products in development cannot be sold if we do not maintain or gain regulatory approval.
In October 2010, we initiated a voluntary recall of certain lots of ENBREL due to identification of cracks in a small number of the glass syringes which may have resulted in product leakage and syringe breakage. Further, beginning in September 2010, we initiated a voluntary recall of certain lots of EPOGEN® and J&J voluntarily recalled certain lots of PROCRIT®, manufactured by us, because a small number of vials in each lot were found to contain glass lamellae (extremely thin, barely visible glass flakes) which we believed was a result of the interaction of the formulation with glass vials during the shelf life of the product. Both actions were executed in close collaboration with the FDA. We may experience the same or other problems in the future, with respect to EPOGEN® or other of our products, resulting in broader product recalls, adverse event trends, delayed shipments, supply constraints, contract disputes and/or stock-outs of our products, which may adversely affect the sales of our products.
Our ESA products continue to be under review and receive scrutiny by regulatory authorities.
On October 26, 2010, the CMS announced a MEDCAC meeting for January 19, 2011 to examine evidence on the use of ESAs to manage anemia in patients with CKD. On October 18, 2010 the FDA’s CRDAC discussed the results from the TREAT study conducted in patients not on dialysis, and how those results informed the appropriate use of ESAs in patients with CKD. Prior to the CRDAC meeting, we submitted proposed labeling changes to the FDA regarding the use of ESAs in chronic renal failure patients not on dialysis that would limit treatment to patients who are most likely to benefit, specifically those with significant anemia (<10 g/dL), and who are at high risk for transfusion and for whom transfusion avoidance is considered clinically important, including those in whom it is important to preserve kidney transplant eligibility. In addition to narrowing the patient population, we are proposing a more conservative dosing algorithm in these patients. We will continue to work with the FDA to develop information that will optimize the use of ESAs in CKD patients. Although we cannot predict what impact all of these activities could have on our business, the revised ESA labeling or any future labeling changes, including any required in connection with the CRDAC meeting, our ongoing discussions with the FDA regarding the conversion of the format of our ESA U.S. labels in accordance with the Physician’s Labeling Rule or other changes required by the FDA, the outcome from the NCA or MEDCAC meeting, the impact of the approved REMS for ESAs could have a material adverse impact on the coverage, reimbursement and sales of our ESAs, which would have a material adverse effect on our business and results of operations.
We must conduct clinical trials in humans before we can commercialize and sell any of our product candidates or existing products for new indications.
We rely on unaffiliated third-party vendors to perform certain aspects of our clinical trial operations. In the event that any of these vendors has unforeseen issues that negatively impact the quality of its work, our ability to evaluate clinical results may also be negatively impacted. As a result, this could adversely affect our ability to file for or gain regulatory approvals worldwide on a timely basis.
Our sales depend on coverage and reimbursement from third-party payers.

We are required to pay Medicaid rebates on products reimbursed by Medicaid at a rate of 23.1% of the AMP of a product, or if it is greater, the difference between the AMP and the best price available to any non-government customer. The definition of AMP recently changed and we expect the CMS to shortly issue a proposed rule further defining the new AMP definition. Until that rule is issued, we will be required to apply our judgment in certain aspects of the AMP calculation. Once the CMS rule is issued, we will have to determine whether our interpretation of AMP follows the rule or would need to be restated and this could have a material adverse impact on our results of operations.
As referred to above, on October 26, 2010, the CMS announced a second MEDCAC meeting scheduled for January 19, 2011 to further examine currently available evidence on the use of ESAs to manage anemia in patients who have CKD. This development initiates another phase in the process of reviewing and evaluating potential changes in Medicare coverage policies for the use of ESAs in these patients, although we cannot predict the outcome of this meeting.
Under the final rule to implement a bundled prospective payment system for ESRD, ESRD facilities were required to elect, by November 1, 2010, whether they will implement the rule in its entirety or ratably over a four-year period beginning in 2011. As a result, the implementation of the bundled payment system by ESRD facilities, either entirely or ratably beginning in 2011, could have a material adverse impact on the coverage and reimbursement, use and sales of EPOGEN® beginning in 2011, and Sensipar® beginning in 2014.
We expect to face increasing competition from biosimilar products which could impact our profitability.
The FDA held a public meeting on November 2-3, 2010 to seek stakeholder input on the subject and will accept written comments through 2010. The agency has the authority to approve biosimilar products but has not announced whether they will first publish guidance or rules for biosimilar applicants before approving biosimilar products. With the likely introduction of biosimilars in the United States, we may in the future face greater competition from biosimilar products and downward pressure on our product prices, sales and revenues, subject to our ability to enforce our patents.
We rely on third-party suppliers for certain of our raw materials, medical devices and components.
We rely on unaffiliated third-party suppliers for certain raw materials, medical devices and components necessary for the formulation, fill and finish of our products. Certain of these raw materials, medical devices and components are the proprietary products of these unaffiliated third-party suppliers and are specifically cited in our drug application with regulatory agencies so that they must be obtained from that specific sole source or sources and could not be obtained from another supplier unless and until the regulatory agency approved such supplier. We may be unable to obtain these raw materials, medical devices and components if we discover previously unknown or undetected imperfections in raw materials, medical devices or components.
Quality issues which result in unexpected additional demand for certain components may lead to shortages of required raw materials or components (such as we have experienced with EPOGEN® glass vials). We may experience or continue to experience these or other shortages in the future resulting in delayed shipments, supply constraints, contract disputes and/or stock-outs of our products.
As noted above, these supplemental risks should be read in conjunction with those set forth in our risk factors disclosed in Part I, Item 1A, of our Annual Report on Form 10-K for the fiscal year ended December 31, 2009 and the changes to these 10-K risk factors set forth in our Quarterly Reports on Form 10-Q for the periods ended March 31, 2010 and June 30, 2010, which are incorporated herein by reference. Specifically, the risk factors entitled “Our current products and products in development cannot be sold if we do not gain or maintain regulatory approval,” ”Our sales depend on coverage and reimbursement from third-party payer,” “Our business may be affected by litigation and government investigations” and “We expect to face increasing competition from biosimilar products which could impact our profitability” in our Annual Report on Form 10-K for the fiscal year ended December 31, 2009 were supplemented in Part II, Item 1A. Risk Factors of our Quarterly Report on Form 10-Q for the period ended March 31, 2010. Further, the risk factors entitled “Our current products and products in development cannot be sold if we do not gain or maintain regulatory approval,” “Our ESA products continue to be under review and receive scrutiny by regulatory authorities,” ”Our sales depend on coverage and reimbursement from third-party payer,” “If our intellectual property positions are challenged, invalidated, circumvented or expire, or if we fail to prevail in present and future intellectual property litigation, our business could be adversely affected,” “We expect to face increasing competition from biosimilar products which could impact our profitability,” “We must conduct clinical trials in humans before we can commercialize and sell any of our product candidates or existing products for new indications,” “We may not be able to develop commercial products,” “Our business may be affected by litigation and government investigations,” “We rely on single-source third-party suppliers for certain of our raw materials, medical devices and components,” “Manufacturing difficulties, disruptions or delays could limit supply of our products and limit our product sales,” and “We manufacture and formulate, fill and finish substantially all our products at our Puerto Rico manufacturing facility and manufacture and formulate, fill and finish substantially all of our clinical supply at our Thousand Oaks, California manufacturing facility; if significant natural disasters 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” in our Annual Report on Form 10-K for the fiscal year ended December 31, 2009 and in our Quarterly Report on Form 10-Q for the period ended March 31, 2010, as applicable, were supplemented in Part II, Item IA. Risk Factors in our Quarterly Report on Form 10-Q for the period ended June 30, 2010.
