Recently Issued Accounting Standards In May 2011, the Financial Accounting Standards Board (the “FASB”) issued Accounting Standards Update (“ASU”) No. 2011-04, “Amendments to Achieve Common Fair Value Measurement and Disclosure Requirements in U.S. GAAP and IFRSs”, an amendment to Accounting Standards Codification Topic 820, “Fair Value Measurements and Disclosures”.

In June 2011, the FASB issued ASU No. 2011-05, “Presentation of Comprehensive Income”.

In December 2011, the FASB issued ASU 2011-12, “Deferral of the Effective Date for Amendments to the Presentation of Reclassifications of Items Out of Accumulated Other Comprehensive Income in Accounting Standards Update No. 2011-05”, which defers the requirement to present on the face of the financial statements reclassification adjustments for items that are reclassified from other comprehensive income to net income while the FASB further deliberates this aspect of the proposal. ASU No. 2011-05, as amended by ASU 2011-12, is effective for interim and annual reporting periods beginning after December 15, 2011.

In September 2011, the FASB issued ASU No. 2011-08, “Intangibles-Goodwill and Other (Topic 350): Testing Goodwill for Impairment”. This standard is intended to simplify goodwill impairment testing by adding a qualitative review step to assess whether a quantitative impairment analysis is necessary. The standard permits an entity to perform a qualitative assessment to determine whether it is more likely than not that the fair value of a reporting unit is less than its carrying value. If the entity concludes that this is the case, it must perform the currently prescribed two-step goodwill impairment test. Otherwise, the two-step goodwill impairment test is not required. ASU No. 2011-08 is effective for fiscal years beginning after December 15, 2011, with earlier adoption permitted. We do not expect the adoption of this standard to have a material impact on our consolidated results of operations, financial position, cash flows, or notes to the consolidated financial statements.
