Recently Adopted Accounting Standards

In January 2012, we adopted authoritative guidance issued in 2011, the purpose of which was to achieve consistent fair value measurements and to clarify certain disclosure requirements for fair value measurements. The guidance includes clarification about when the concept of highest and best use is applicable to fair value measurements, requires quantitative disclosures about inputs used and qualitative disclosures about the sensitivity of recurring Level 3 measurements, and requires the classification of all assets and liabilities measured at fair value in the fair value hierarchy, including those assets and liabilities which are not recorded at fair value but for which fair value is disclosed. The adoption of this guidance did not have a material impact on our consolidated financial statements. See Note 9. Fair Value Measurements and Derivative Instruments for our disclosures required under this guidance.

In January 2012, we adopted authoritative guidance issued in 2011 on the presentation of comprehensive income which requires an entity to present components of net income and other comprehensive income in one continuous statement, referred to as the statement of comprehensive income, or in two separate but consecutive statements. The new guidance eliminates the option to report other comprehensive income and its components in the statement of changes in equity. We elected to present this information using one continuous statement. See our consolidated statements of comprehensive income.
