Recently Issued Accounting Pronouncements	Recent Accounting Pronouncements In June 2011, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update ("ASU") 2011-05, Comprehensive Income (Topic 220): Presentation of Comprehensive Income. The ASU amends guidance for the presentation of comprehensive income. The amended guidance requires 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. The previous option to report other comprehensive income and its components in the statement of shareholders’ equity has been eliminated. Although the new guidance changes the presentation of comprehensive income, there are no changes to the components that are recognized in net income or other comprehensive income under existing guidance. In the first quarter of fiscal 2013, we revised our presentation of comprehensive income to conform to the guidance in this ASU. In September 2011, the FASB issued ASU 2011-08, Intangibles – Goodwill and Other (Topic 350): Testing Goodwill for Impairment. Under this new standard, entities testing goodwill for impairment now have an option of performing a qualitative assessment before having to calculate the fair value of a reporting unit. If an entity determines, on the basis of qualitative factors, that it is more-likely-than-not that the fair value of the reporting unit is less than the carrying amount, the existing quantitative impairment test is required. Otherwise, no further impairment testing is required. This ASU is effective for impairment tests after April 29, 2012. The adoption of this standard did not have a material impact on our consolidated results of operations or financial condition, as this ASU impacts only the analysis performed. In July 2012, the FASB issued ASU 2012-02, Intangibles - Goodwill and Other (Topic 350): Testing Indefinite-Lived Intangible Assets for Impairment. The amended guidance gives entities the option to perform a qualitative impairment assessment to determine whether it is more-likely-than-not that an indefinite-lived intangible asset is impaired. An entity must identify and evaluate changes in economic, industry and entity-specific events and circumstances that could affect the significant inputs used to determine the fair value of an indefinite-lived intangible asset and whether it is more-likely-than-not that the fair value exceeds its carrying amount. ASU 2012-02 is effective for annual and interim impairment tests performed for fiscal years beginning after September 15, 2012, with early adoption permitted. The adoption of this amended guidance is not expected to have a material impact on our consolidated results of operations or financial condition, as the ASU impacts only the analysis to be performed.
