Summary of Significant Accounting Policies [Abstract]
Newly Adopted Accounting Standards	Newly Adopted Accounting Standards Fair Value ASU No. 2011-04, "Fair Value Measurement (Topic 820): Amendments to Achieve Common Fair Value Measurement and Disclosure Requirements in U.S. GAAP and IFRSs" Effective December 29, 2011, we adopted ASU 2011-04, which provides a consistent definition of fair value and ensures that the fair value measurement and disclosure requirements are similar between U.S. GAAP and IFRS. The amended guidance changes certain fair value measurement principles and enhances the disclosure requirements particularly for Level 3 fair value measurements. The adoption did not have a material impact on the disclosures included in our Condensed Consolidated Financial Statements. Comprehensive Income ASU No. 2011-05, "Comprehensive Income (Topic 220): Presentation of Comprehensive Income" Effective December 29, 2011, we adopted ASU 2011-05, which amends existing guidance to allow only two options for presenting the components of net income and other comprehensive income: (1) in a single continuous statement of comprehensive income or (2) in two separate but consecutive financial statements consisting of an income statement followed by a statement of other comprehensive income. The new guidance requires retrospective application. The adoption concerns presentation and disclosure only and did not have an impact on our financial position or results of operations. ASU No. 2011-12, "Comprehensive Income (Topic 220): Deferral of the Effective Date for Amendments to the Presentation of Reclassifications of Items Out of Accumulated Other Comprehensive Income in Accounting Standards Update No. 2011-05" Effective December 29, 2011, we adopted ASU 2011-12, which effectively defers the changes in ASU 2011-05 that relate to the presentation of reclassification out of accumulated other comprehensive income. All other requirements of ASU 2011-05 are not affected by this update. The adoption did not have a material impact on our Condensed Consolidated Financial Statements. Goodwill ASU No. 2011-08, "Intangibles-Goodwill and Other (Topic 350): Testing Goodwill for Impairment" Effective December 29, 2011, we adopted ASU 2011-08, which modifies the impairment test for goodwill. Under the new guidance, an entity is permitted to make a qualitative assessment of whether it is more likely than not that the reporting unit's fair value is less than the carrying value before applying the two-step goodwill impairment model that is currently in place. If it is determined through the qualitative assessment that a reporting unit's fair value is more likely than not greater than its carrying value, the remaining impairment steps would be unnecessary. The qualitative assessment is optional, allowing companies to go directly to the quantitative assessment. The adoption did not have any impact on our Condensed Consolidated Financial Statements.
Accounting Standards to be Adopted	Accounting Standards to be Adopted Intangibles ASU No. 2012-02, "Intangibles—Goodwill and Other (Topic 350): Testing Indefinite-Lived Intangible Assets for Impairment" In July 2012, the FASB issued ASU 2012-02, which modifies the impairment test for indefinite-lived intangible assets. Under the new guidance, an entity is permitted to make a qualitative assessment of whether it is more likely than not that the indefinite-lived intangible asset is impaired. If it is determined through the qualitative assessment that the indefinite-lived intangible asset's fair value is more likely than not greater than its carrying value, the quantitative impairment calculations would be unnecessary. The qualitative assessment is optional, allowing companies to go directly to the quantitative assessment. The guidance is effective for impairment tests for fiscal years beginning after September 15, 2012 (our fiscal 2013). We do not believe the adoption of this guidance will have a material impact on our Condensed Consolidated Financial Statements.
