Recently Issued Accounting Standards [Abstract]
Recently Issued Accounting Standards	(2) Recently Issued Accounting Standards In June 2011, the Financial Accounting Standards Board (“FASB”) issued authoritative guidance on the presentation of comprehensive income that will become effective for us beginning January 1, 2012, with earlier adoption permitted. This standard eliminates the current option to report other comprehensive income and its components in the statement of changes in equity. We do not believe the adoption of this guidance will impact our consolidated financial condition or results of operations. In September 2011, the FASB issued authoritative guidance on testing goodwill for impairment that will become effective for us beginning January 1, 2012, with earlier adoption permitted if we have not yet performed our 2011 annual impairment test or issued our financial statements. The revised standard is intended to reduce the cost and complexity of the annual goodwill impairment test by providing entities an option to perform a qualitative assessment to determine whether further impairment testing is necessary. We are currently assessing the potential impact of the adoption of this guidance on our financial statements.
