New Accounting Pronouncements [Abstract]
New Accounting Pronouncements	Note 2. New Accounting Pronouncements In May 2011, the Financial Accounting Standards Board ("FASB") issued amended guidance on fair value measurement and related disclosures. The new guidance clarified the concepts applicable for fair value measurement of non-financial assets and requires the disclosure of quantitative information about the unobservable inputs used in a fair value measurement. This guidance will be effective for reporting periods beginning after December 15, 2011, and will be applied prospectively. The adoption of this amendment in 2012 did not have a material effect on the presentation of our consolidated financial statements. In June and December 2011, the FASB issued two Accounting Standard Updates ("ASUs"), which amend guidance for the presentation of comprehensive income. The amended guidance requires an entity to present components of net income and other comprehensive income in one continuous statement, referred to as the statement of comprehensive income, or in two separate, but consecutive statements. The current option to report other comprehensive income and its components in the statement of stockholders' equity has been eliminated. Although the new guidance changes the presentation of comprehensive income, there are no changes to the components that are recognized in net income or other comprehensive income under existing guidance. We adopted these ASUs using two consecutive statements in the first quarter of 2012 for all periods presented. In December 2011, the FASB issued an ASU for balance sheets, which contains new disclosure requirements regarding the nature of an entity's rights of set off and related arrangements associated with its financial instruments and derivative instruments. Under generally accepted accounting principles in the United States, certain derivative and repurchase agreement arrangements are granted exceptions from the general off-setting model. The new disclosure requirement will provide financial statement users information regarding both gross and net exposures. This guidance is effective for annual and interim financial statements beginning on or after January 1, 2013. Retrospective application is required. We do not expect a material impact on our consolidated financial statements as a result of the adoption of this ASU.
