Summary of significant accounting policies</b> </div> <div align="left" style="font-size: 10pt; margin-top: 10pt"><i>Business</i> </div> <div align="justify" style="font-size: 10pt; margin-top: 10pt; text-indent:8%">Amgen Inc. (including its subsidiaries, referred to as &#8220;Amgen,&#8221; &#8220;the Company,&#8221; &#8220;we,&#8221; &#8220;our&#8221; or &#8220;us&#8221;) 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. </div> <div align="left" style="font-size: 10pt; margin-top: 10pt"><i>Basis of presentation</i> </div> <div align="justify" style="font-size: 10pt; margin-top: 10pt; text-indent:8%">The financial information for the three months ended March&#160;31, 2011 and 2010 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. </div> <div align="justify" style="font-size: 10pt; margin-top: 10pt; text-indent:8%">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&#160;31, 2010. </div> <div align="left" style="font-size: 10pt; margin-top: 10pt"><i>Principles of consolidation</i> </div> <div align="justify" style="font-size: 10pt; margin-top: 10pt; text-indent:8%">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. </div> <div align="left" style="font-size: 10pt; margin-top: 10pt"><i>Use of estimates</i> </div> <div align="justify" style="font-size: 10pt; margin-top: 10pt; text-indent:8%">The preparation of condensed consolidated financial statements in conformity with accounting principles generally accepted in the United States (GAAP)&#160;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. </div> <div align="left" style="font-size: 10pt; margin-top: 10pt"><i>Revenue recognition for arrangements with multiple-deliverables</i> </div> <div align="justify" style="font-size: 10pt; margin-top: 10pt; text-indent:8%">From time to time, we enter into arrangements for the research and development (R&#038;D), manufacture and/or commercialization of products and product candidates. These arrangements may require us to deliver various rights, services and/or goods across the entire life cycle of a product or product candidate, including (i)&#160;intellectual property rights/license, (ii)&#160;R&#038;D services, (iii)&#160;manufacturing services and/or (iv)&#160;commercialization services. The underlying terms of these arrangements generally provide for consideration to Amgen in the form of non-refundable upfront license payments, R&#038;D and commercial performance milestone payments, cost sharing and/or royalty payments. </div> <div align="justify" style="font-size: 10pt; margin-top: 10pt; text-indent:8%">In October&#160;2009, the Financial Accounting Standards Board issued a new accounting standard which amends the guidance on the accounting for arrangements involving the delivery of more than one element. This standard addresses the determination of the unit(s) of accounting for multiple-element arrangements and how the arrangement&#8217;s consideration should be allocated to each unit of accounting. The Company adopted this new accounting standard on a prospective basis for all multiple-element arrangements entered into on or after January&#160;1, 2011 and for any multiple-element arrangements that were entered into prior to January&#160;1, 2011 but materially modified on or after January&#160;1, 2011. </div> <div align="justify" style="font-size: 10pt; margin-top: 10pt; text-indent:8%">Pursuant to the new standard, each required deliverable is evaluated to determine if it qualifies as a separate unit of accounting. For Amgen this determination is generally based on whether the deliverable has &#8220;stand-alone value&#8221; to the customer. The arrangement&#8217;s consideration is then allocated to each separate unit of accounting based on the relative selling price of each deliverable. The estimated selling price of each deliverable is determined using the following hierarchy of values: (i)&#160;vendor-specific objective evidence of fair value, (ii)&#160;third-party evidence of selling price, and (iii)&#160;best estimate of selling price (BESP). The BESP reflects our best estimate of what the selling price would be if the deliverable was regularly sold by us on a stand-alone basis. We expect, in general, to use the BESP for allocating consideration to each deliverable. In general, the consideration allocated to each unit of accounting is then recognized as the related goods or services are delivered limited to the consideration that is not contingent upon future deliverables. </div> <div align="justify" style="font-size: 10pt; margin-top: 10pt; text-indent:8%">For multiple-element arrangements entered into prior to January&#160;1, 2011 and not materially modified thereafter, we continue to apply our prior accounting policy with respect to such arrangements. Under this policy, in general, revenue from non-refundable, upfront fees related to intellectual property rights/licenses where we have continuing involvement is recognized ratably over the estimated period of ongoing involvement because there is no objective and reliable evidence of fair value for any undelivered item to allow the delivered item to be considered a separate unit of accounting. This requirement with respect to the fair value of undelivered items was eliminated in the newly issued accounting standard. In general, the consideration with respect to the other deliverables is recognized when the goods or services are delivered. </div> <div align="justify" style="font-size: 10pt; margin-top: 10pt; text-indent:8%">Under all of our multiple-element arrangements, consideration associated with at risk substantive performance milestones is recognized as revenue upon the achievement of the related milestone, as defined in the respective agreements. </div> <div align="justify" style="font-size: 10pt; margin-top: 10pt; text-indent:8%">The impact of adopting this new accounting standard is dependent on the terms and conditions of any future arrangement that we may enter into that includes multiple-deliverables, however, its adoption is not expected to have a material impact on our consolidated results of operations or financial position. The primary impact of adopting the new accounting standard is expected to be the earlier recognition of revenue associated with delivering rights to the underlying intellectual property. </div> <div align="justify" style="font-size: 10pt; margin-top: 10pt; text-indent:8%">The adoption of this accounting standard did not have a material impact on our condensed consolidated results of operations or financial position for the three months ended March&#160;31, 2011. Our consolidated results of operations or financial position for 2010 also would not have been materially impacted if the accounting standard had been adopted on January&#160;1, 2010. </div> <div align="left" style="font-size: 10pt; margin-top: 10pt"><i>Inventories</i> </div> <div align="justify" style="font-size: 10pt; margin-top: 10pt; text-indent:8%">Inventories are stated at the lower of cost or market. Cost, which includes amounts related to materials, labor and overhead, is determined in a manner which approximates the first-in, first-out method. Cost also includes the impact of the recently enacted Puerto Rico excise tax related to our manufacturing operations in Puerto Rico. The Company capitalizes inventories produced in preparation for product launches when the related product candidates are considered to have a high probability of regulatory approval and the related costs are expected to be recoverable through the commercialization of the product. See Note 7, Inventories. </div> <div align="left" style="font-size: 10pt; margin-top: 10pt"><i>Property, plant and equipment, net</i> </div> <div align="justify" style="font-size: 10pt; margin-top: 10pt; text-indent:8%">Property, plant and equipment is recorded at historical cost, net of accumulated depreciation and amortization of $5.3&#160;billion and $5.2&#160;billion as of March&#160;31, 2011 and December&#160;31, 2010, respectively. </div> <div align="left" style="font-size: 10pt; margin-top: 10pt"><i>Business combinations</i> </div> <div align="justify" style="font-size: 10pt; margin-top: 10pt; text-indent:8%">Business combinations are accounted for using the acquisition method of accounting. Under the acquisition method, assets acquired, including in-process research and development (IPR&#038;D) projects, and liabilities assumed are recorded at their respective fair values as of the acquisition date in our condensed consolidated financial statements. The excess of the acquisition date fair value of consideration over the fair value of the net assets acquired is recorded as goodwill. Contingent consideration obligations incurred in connection with a business combination are recorded at their fair values on the acquisition date. We revalue these obligations each subsequent reporting period until the related contingencies are resolved and record changes in their fair values in earnings. See Note 2, Acquisitions. </div> <!-- Folio --> <!-- /Folio --> </div> <!-- PAGEBREAK --> <div style="font-family: 'Times New Roman',Times,serif"> <div align="center" style="font-size: 10pt; margin-top: 0pt"> <b> </b> <b> </b> </div> </div> <!--DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd" --> <!-- Begin Block Tagged NotefalsefalsefalsefalsefalseOtherus-types:textBlockItemTypestringThis element may be used to describe all significant accounting policies of the reporting entity.Reference 1: http://www.xbrl.org/2003/role/presentationRef -Publisher AICPA -Name Accounting Principles Board Opinion (APB) -Number 22 -Paragraph 8 falsefalse12Summary of significant accounting policiesUnKnownUnKnownUnKnownUnKnownfalsetrue
