Summary of Significant Accounting Policies (Policies)	9 Months Ended
Sep. 30, 2012
Recently Adopted Accounting Pronouncements	*Recently Adopted Accounting Pronouncements* On January 1, 2012, we adopted the new Financial Accounting Standards Board (“FASB”) guidance on the presentation of comprehensive income. Specifically, the new guidance allows 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, which is the approach we have selected. The new guidance eliminated the option to report other comprehensive income and its components in the statement of changes in stockholders’ equity. While the new guidance changed the presentation of comprehensive income, there were no changes to the components that are recognized in net income or other comprehensive income from that of previous accounting guidance. In July 2012, the FASB issued amended guidance that simplifies how entities test indefinite-lived intangible assets, other than goodwill, for impairment. Under the amended guidance, an entity testing an indefinite-lived intangible asset for impairment has the option of performing a qualitative assessment before calculating the fair value of the asset. If the entity determines, on the basis of qualitative factors, that the fair value of the indefinite-lived intangible asset is not more likely than not impaired, the entity would not need to calculate the fair value of the asset. The amended guidance is effective for annual and interim impairment tests performed for fiscal years beginning after September 15, 2012, with early adoption permitted. On October 1, 2012, we early adopted this guidance and our adoption did not materially impact our consolidated financial statements.
