Accounting Pronouncements In May 2011, 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 (“ASU 2011-04”), which changes the wording used to describe many of the requirements in U.S. GAAP for measuring fair value and disclosing information about fair value measurements. Some of the amendments clarify the FASB’s intent about the application of existing fair value measurement requirements while other amendments change a particular principle or requirement for measuring fair value or for disclosing information about fair value measurements. The amendments in this ASU are effective prospectively for interim and annual periods beginning after December 15, 2011, with no early adoption permitted. The Company does not expect the adoption of this standard to have a material impact on its consolidated financial statements. In June 2011, the FASB issued ASU No. 2011-05, Presentation of Comprehensive Income (“ASU 2011-05”), which eliminates the option to present components of other comprehensive income as part of the statement of changes in stockholders’ equity. The amendments in this standard require that an entity present the total of comprehensive income, the components of net income, and the components of other comprehensive income in a single continuous statement of comprehensive income or in two separate but consecutive statements. Under either method, the entity is required to present on the face of the financial statements reclassification adjustments for items that are reclassified from other comprehensive income to net income in the statement(s) where the components of net income and the components of other comprehensive income are presented. However, in December 2011 this ASU was amended by ASU No. 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 (“ASU 2011-12”), which defers the requirement to present on the face of the financial statements the effects of reclassifications out of accumulated other comprehensive income on the components of net income and other comprehensive income. For public entities, the amendments in these ASUs are effective for fiscal years, and interim periods within those years, beginning after December 15, 2011 and are to be applied retrospectively, with early adoption permitted. The Company early adopted both ASU 2011-05 and ASU 2011-12 at December 31, 2011 with no material impact to its consolidated financial statements.
