Our consolidated financial statements reflect our financial
statements, those of our wholly-owned subsidiaries and those of
certain variable interest entities in which we are the primary
beneficiary. For such consolidated entities in which we own less
than a 100% interest, we record net income (loss) attributable
to noncontrolling interest in our consolidated statements of
income equal to the percentage of the economic or ownership
interest retained in the collaborative arrangement or joint
venture by the respective noncontrolling parties. All material
intercompany balances and transactions have been eliminated in
consolidation.

In determining whether we are the primary beneficiary of an
entity, we consider a number of factors, including our ability
to direct the activities that most significantly affect the
entity’s economic success, our contractual rights and
responsibilities under the arrangement and the significance of
the arrangement to each party. These considerations impact the
way we account for our existing collaborative and joint venture
relationships and determines the consolidation of companies or
entities with which we have collaborative or other arrangements.

The preparation of consolidated financial statements in
accordance with U.S. GAAP requires management to make
estimates and judgments that may affect the reported amounts of
assets, liabilities, revenues and expenses, and related
disclosure of contingent assets and liabilities. On an on-going
basis, we evaluate our estimates and judgments, including those
related to revenue recognition and related allowances,
marketable securities, derivatives and hedging activities,
inventory, impairments of long-lived assets including intangible
assets, impairments of goodwill, the consolidation of variable
interest entities, income taxes including the valuation
allowance for deferred tax assets, valuation of investments,
research and development expenses, contingencies and litigation,
and share-based payments. We base our estimates on historical
experience and on various other assumptions that are believed to
be reasonable, the results of which form the basis for making
judgments about the carrying values of assets and liabilities.
Actual results may differ from these estimates under different
assumptions or conditions.
