In June 2011, the Financial Accounting Standards Board ("FASB") issued ASU No. 2011-05, Comprehensive Income (Topic 220)-Presentation of Comprehensive Income (ASU 2011-05), to require an entity to present the total of comprehensive income, the components of net income, and the components of other comprehensive income either in a single continuous statement of comprehensive income or in two separate but consecutive statements. ASU 2011-05 eliminates the option to present the components of other comprehensive income as part of the statement of equity. ASU 2011-05 is to be applied retrospectively and is effective for fiscal years and interim periods within those years, beginning after December 15, 2011. The Company adopted the standard effective January 1, 2012. The standard changed the presentation of the Company's condensed consolidated financial statements but did not affect the calculation of net income, comprehensive income or earnings per share.
 
In May 2011, the FASB issued ASU 2011-04, Fair Value Measurements (Topic 820): Amendments to Achieve Common Fair Value Measurement and Disclosure Requirements in U.S. GAAP and IFRSs (ASU 2011-04). The update to ASC 820, Fair Value Measurement. was issued to clarify the FASB Board's intent about the application of existing fair value measurement and disclosure requirements and improve the comparability of fair value measurements presented and disclosed in financial statements. The amendment expands the quantitative disclosures about fair value measurements categorized within Level 3 of the fair value hierarchy, including the valuation process used by the reporting entity and the sensitivity of the fair value measurement to changes in unobservable inputs. The amendment also specifies that the highest and best use valuation premise only applies to nonfinancial assets, and requires expanded disclosure about the reporting entity's use of a nonfinancial asset in a way that differs from the asset's highest and best use. The amendment also requires disclosure of the categorization by level of the fair value hierarchy for items that are not measured at fair value in the financial statements, but for which fair value is required to be disclosed. ASU 2011-04 was adopted by the Company on January 1, 2012. The adoption of ASU 2011-04 did not have a material impact on the Company's condensed consolidated financial statements and disclosures.
