Recent Accounting Pronouncements In December 2011, FASB issued ASU No. 2011-12, Comprehensive Income (Topic 220): Deferral of the Effective Date for Amendments to the Presentation of Reclassifications of Items Out of Accumulated Other Comprehensive Income in ASU 2011-05, which indefinitely defers the requirement that companies present reclassification adjustments for each component of accumulated other comprehensive income in both net income and other comprehensive income on the face of the financial statements for all periods presented. Entities should continue to report reclassifications out of accumulated other comprehensive income consistent with the presentation requirements in effect prior to ASU 2011-05. All other requirements in ASU 2011-05 are not affected by this update, including the requirement to report comprehensive income either in a single continuous statement or in two separate but consecutive financial statements. Public entities should apply these requirements for fiscal years, and interim periods within those years, beginning after December 15, 2011. We have reported the required information in the accompanying Consolidated Statements of Comprehensive Income. In September 2011, FASB issued ASU No. 2011-08, Intangibles – Goodwill and Other (Topic 350): Testing Goodwill for Impairment. Under the amendments in this update, an entity has the option to first assess qualitative factors to determine whether the existence of events or circumstances leads to a determination that it is more likely than not that the fair value of a reporting unit is less than its carrying amount. If, after assessing the totality of events or circumstances, an entity determines it is not more likely than not that the fair value of a reporting unit is less than its carrying amount, then performing the two-step impairment test is unnecessary. However, if an entity concludes otherwise, then it is required to perform the first step of the two-step impairment test by calculating the fair value of the reporting unit and comparing the fair value with the carrying amount of the reporting unit, as described in the accounting guidance. The guidance in ASU 2011-08 also provides entities with the option to bypass the qualitative assessment for any reporting unit in any period and proceed directly to performing the first step of the two-step goodwill impairment test and an entity may resume performing the qualitative assessment in any subsequent period. ASU 2011-08 does not change current accounting guidance for testing other indefinite-lived intangible assets for impairment. This guidance is effective for fiscal years beginning after December 15, 2011. Early adoption is permitted, including annual and interim goodwill impairment tests performed prior to September 15, 2011. This ASU did not have a material impact on our financial condition, results of operations or financial statement disclosures.
