New Accounting Pronouncements	New Accounting Pronouncements In May 2011, the FASB issued ASU No. 2011-04, “Fair Value Measurement (Topic 820) - Amendments to Achieve Common Fair Value Measurement and Disclosure Requirements in U.S. GAAP and IFRS,” which amends ASC 820 providing consistent guidance on fair value measurement and disclosure requirements between U.S. GAAP and International Financial Reporting Standards. ASU 2011-04 is effective for fiscal years beginning after December 15, 2011. The adoption of ASU 2011-04 did not have a material impact on our consolidated financial statements. In June 2011, the FASB issued ASU 2011-05, “Presentation of Comprehensive Income.” ASU 2011-05 requires the components of net income and other comprehensive income to be either presented in one continuous statement, referred to as the statement of comprehensive income, or in two separate, consecutive statements. While ASU 2011-05 changes the presentation of comprehensive income, there are no changes to the components that are recognized in net income or other comprehensive income under current accounting guidance. This new guidance is effective for the Company beginning February 1, 2012 and requires retrospective application. As this guidance only amends the presentation of the components of comprehensive income, the adoption did not have an impact on the Company's consolidated financial position or results of operations.
