</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) 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 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&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) intellectual property rights/license, (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 non-refundable
upfront license payments, R&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 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’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 1, 2011 and for any multiple-element
arrangements that were entered into prior to January 1, 2011 but materially modified on or after
January 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 “stand-alone value” to the customer. The arrangement’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) vendor-specific objective evidence of fair value, (ii) third-party
evidence of selling price, and (iii) 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 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 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 1, 2010.

preparation for product launches when the related product candidates are considered to have a high

commercialization of the product. See Note 7, Inventories.
