Recent Accounting Pronouncements	2. Recent Accounting Pronouncements *Accounting Standards Adopted in the Six Months Ended June 30, 2011* On January 1, 2011, we prospectively adopted Financial Accounting Standards Board (“FASB”) Accounting Standards Update (“ASU”) 2009-13, Multiple Deliverable Revenue Arrangements, (“ASU 2009-13”) and ASU 2010-17, Revenue Recognition—Milestone Method, (“ASU 2010-17”). ASU 2009-13 applies to all deliverables in contractual arrangements in which a vendor will perform multiple revenue-generating activities. ASU 2010-17 defines a milestone and determines when it may be appropriate to apply the milestone method of revenue recognition for research or development transactions. These pronouncements are codified in FASB Accounting Standards Codification^TM (“ASC”) Topic 605, Revenue Recognition. Adoption of these pronouncements did not have a material effect on our consolidated financial statements. *New Accounting Pronouncements Not Yet Adopted* In May 2011, the FASB issued ASU 2011-04, Fair Value Measurement: Amendments to Achieve Common Fair Value Measurement and Disclosure Requirements in U.S. GAAP and IFRSs, (“ASU 2011-04”), which is codified in ASC Topic 820, Fair Value Measurement. This pronouncement changes certain fair value measurement guidance and expands certain disclosure requirements. ASU 2011-04 will be effective for our fiscal year that begins January 1, 2012, and is to be applied prospectively. We do not expect that adoption of this pronouncement on January 1, 2012, will have a material effect on our consolidated financial statements. In June 2011, the FASB issued ASU 2011-05, Presentation of Comprehensive Income, (“ASU 2011-05”), which is codified in ASC Topic 220, Comprehensive Income. This pronouncement requires companies to present items of net income, items of other comprehensive income and total comprehensive income in one continuous statement or two separate but consecutive statements and will be effective for our fiscal year that begins January 1, 2012. ASU 2011-05 is to be applied retrospectively, and early adoption is permitted. Adoption of this pronouncement will not have a material effect on our consolidated financial statements.
