Accounting Policies [Abstract]
Recently Issued Accounting Pronouncements	In July 2012, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update ("ASU") 2012-02, "Intangibles - Goodwill and Other (Topic 350): Testing Indefinite-Lived Intangible Assets for Impairment." The FASB amended its guidance on testing of indefinite-lived intangible assets for impairment. Under the amended guidance, companies may perform a qualitative assessment to determine whether further impairment testing is necessary, similar to the amended goodwill impairment testing guidance noted below. The guidance for indefinite-lived intangible assets is effective for annual and interim tests performed for fiscal years beginning after September 15, 2012, with an option for early adoption. We adopted ASU 2012-02 in the first quarter of fiscal 2013. As we do not have any indefinite-lived intangible assets, this pronouncement does not have an effect on our consolidated financial statements. In June 2011, the FASB issued ASU No. 2011-05, “Comprehensive Income (Topic 220): Presentation of Comprehensive Income” and was subsequently amended in December 2011. This guidance eliminates the option to report other comprehensive income and its components in the consolidated statement of stockholders' equity. Rather it requires that all non-owner changes in stockholders' equity be presented in either a single continuous statement of comprehensive income or in two separate but consecutive statements. This guidance also requires us to present on the face of the financial statements any reclassification adjustments for items that are reclassified from other comprehensive income to net income. The guidance is effective for fiscal years, and interim periods within those years, beginning after December 15, 2011. In December 2011, FASB issued ASU No. 2011-12 which amends this guidance and defers only the presentation of reclassification of items out of accumulated comprehensive income. We adopted the guidance for ASU No. 2011-05 and early adopted the guidance for ASU No. 2011-12 in the first quarter of fiscal 2013, with comprehensive income shown as a separate statement immediately following the condensed consolidated statements of operations. This statement includes the presentation of items that are reclassified out of accumulated comprehensive income. Since the new guidance only relates to presentation, its adoption did not impact our consolidated financial position, results of operations, or cash flows.
