Newly Issued Accounting Pronouncements [Abstract]
Newly Issued Accounting Pronouncements	Newly Issued Accounting Pronouncements In May 2011, the FASB issued ASU No. 2011-04, “Amendments to Achieve Common Fair Value Measurement and Disclosure Requirements in U.S. GAAP and IFRSs,” which amends previous guidance resulting in common fair value measurement and disclosure requirements between GAAP and International Financial Reporting Standards. The amendments both clarify the application of existing fair value measurement requirements and changes certain principles or requirements for measuring fair value or for disclosing information about fair value measurements. The provisions of this update were effective for us at January 1, 2012. The adoption of this update did not materially impact our consolidated financial statements. In June 2011, the FASB issued ASU No. 2011-05, “Presentation of Comprehensive Income,” which amends previous guidance by requiring all nonowner changes in equity to be presented in either a single continuous statement of comprehensive income or in two separate but consecutive statements. In addition, an entity will be required to present on the face of the financial statements, reclassification adjustments for items reclassified from other comprehensive income to net income. In December 2011, the FASB issued ASU No. 2011-12, “Deferral of 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 primarily defers ASU No. 2011-05's provision of requiring the presentation of other comprehensive income reclassification adjustments on the face of the financial statements. All other provisions of ASU No. 2011-05 were effective for us at December 31, 2011 upon our early adoption, and this update did not materially impact our consolidated financial statements. In December 2011, the FASB issued ASU No. 2011-11, “Disclosures about Offsetting Assets and Liabilities,” which requires entities to provide new disclosures about offsetting and related arrangements for financial instruments and derivatives. The provisions of ASU No. 2011-11 are effective for us on January 1, 2013, and are required to be applied retrospectively. We do not expect the adoption of this update to have a material impact on our consolidated financial statements.
