Recent Accounting Pronouncements	Recent Accounting Pronouncements In May 2011, the Financial Accounting Standards Board ("FASB") issued amended guidance and disclosure requirements for fair value measurements. This guidance provides a consistent definition of fair value and ensures that the fair value measurement and disclosure requirements are similar between U.S. GAAP and international financial reporting standards. The guidance changes certain fair value measurement principles and enhances the disclosure requirements, particularly for Level 3 fair value measurements. The Company adopted this guidance during the first quarter of 2012. The adoption of the guidance did not have a material impact on the Company's consolidated financial statements. In June 2011, the FASB issued amended disclosure requirements for the presentation of comprehensive income. The amended guidance eliminates the option to present components of other comprehensive income (“OCI”) as part of the statement of changes in equity. Under the amended guidance, all changes in OCI are to be presented either in a single continuous statement of comprehensive income or in two separate but consecutive financial statements. The Company adopted this guidance during the first quarter of 2012. There is no impact to the Company's consolidated financial results as the amendments relate only to changes in financial statement presentation. In September 2011, the FASB issued amended guidance that simplifies how entities test goodwill for impairment. Under the amended guidance, after assessment of certain qualitative factors, if it is determined to be more likely than not that the fair value of a reporting unit is less than its carrying amount, entities must perform the quantitative analysis of the goodwill impairment test. Otherwise, the quantitative test(s) are optional. The Company adopted this guidance during the first quarter of 2012. The adoption of the guidance did not have a material impact on the Company's consolidated financial statements.
