Recent Accounting Pronouncements [Abstract]
Recent Accounting Pronouncements	Note 3. Recent Accounting Pronouncements In June 2011, the Financial Accounting Standards Board (“FASB”) issued ASU No. 2011-05, “Comprehensive Income: Presentation of Comprehensive Income.” This new standard requires the presentation 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. The new standard also requires presentation of adjustments for items that are reclassified from other comprehensive income to net income in the statement where the components of net income and the components of other comprehensive income are presented. ASU No. 2011-05 was amended by ASU No. 2011-12, which defers the effective date for amendments to the presentation of reclassification of items out of accumulated other comprehensive income. The remaining updated guidance in ASU No. 2011-05 is effective on a retrospective basis for financial statements issued for interim and annual periods beginning after December 15, 2011 and early adoption is permitted. This guidance affects presentation only and will have no effect on our financial condition, results of operations, or cash flows. In May 2011, the FASB amended ASC 820, “Fair Value Measurements.” This amendment is intended to result in convergence between U.S. GAAP and International Financial Reporting Standards (“IFRS”) requirements for measurement of and disclosures about fair value. This guidance clarifies the application of existing fair value measurements and disclosures, and changes certain principles or requirements for fair value measurements and disclosures. The updated guidance is effective on a prospective basis for financial statements issued for interim and annual periods beginning after December 15, 2011. The adoption of this guidance will not have a material impact on our consolidated financial statements. In September 2011, the FASB issued ASU No. 2011-08, “Testing Goodwill for Impairment.” ASU 2011-08 simplifies the goodwill impairment assessment by permitting a company to make a qualitative assessment of whether it is more likely than not that a reporting unit's fair value is less than its carrying amount before applying the two-step goodwill impairment test. If the conclusion is that it is more likely than not that the fair value of a reporting unit is less than its carrying amount, the company would be required to conduct the current two-step goodwill impairment test. Otherwise, it would not need to apply the two-step test. The early adoption of ASU 2011-08 for our fiscal year ended December 31, 2011 did not have any impact on our financial position, results of operations, or cash flows.
