Accounting Policies [Abstract]
Recent Accounting Pronouncements	Recent Accounting Pronouncements In May 2011, the Financial Accounting Standards Board (the "FASB") issued guidance that expands the existing disclosure requirements for fair value measurements, primarily for Level 3 measurements, which are measurements based on unobservable inputs such as the Company’s own data. This guidance is largely consistent with current fair value measurement principles with few exceptions that do not result in a change in general practice. The guidance was applied prospectively and was effective for interim and annual reporting periods ending after December 15, 2011. The adoption of this guidance did not have a material impact on the Company’s financial position or results of operations as the guidance relates only to disclosure requirements. In June 2011, the FASB issued guidance requiring entities to present items of net income and other comprehensive income either in one continuous statement – referred to as the statement of comprehensive income – or in two separate, but consecutive, statements of net income and other comprehensive income. The new guidance does not change which components of comprehensive income are recognized in net income or other comprehensive income, or when an item of other comprehensive income must be reclassified to net income. In December 2011, the FASB deferred certain provisions of this guidance related to the presentation of certain reclassification adjustments out of accumulated other comprehensive income, by component in both the statement and the statement where the reclassification is presented. This guidance was applied prospectively and was effective for interim and annual reporting periods ended after December 15, 2011. The adoption of this guidance did not have a material impact on the Company’s financial position or results of operations but changed the location of the presentation of other comprehensive income to more closely associate the disclosure with net income. In September 2011, the FASB issued guidance that allows entities to perform a qualitative analysis as the first step in determining whether it is more likely than not that the fair value of a reporting unit is less than its carrying amount. If it is determined that it is not more likely than not that the fair value of the reporting unit is less than its carrying amount, then a quantitative analysis for impairment is not required. The guidance was effective for interim and annual impairment tests for fiscal periods beginning after December 15, 2011. The adoption of this guidance did not have a material impact on the Company's financial position or results of operations.
