Recent Accounting Pronouncements [Abstract]
Recent Accounting Pronouncements	11. Recent Accounting Pronouncements Disclosures about Fair Value Measurements In May 2011, the Financial Accounting Standards Board ("FASB") issued an accounting standards update which amends the definition of fair value measurement principles and disclosure requirements to eliminate differences between U.S. GAAP and International Financial Reporting Standards. The update requires new quantitative and qualitative disclosures about the sensitivity of recurring Level 3 measurement disclosures, as well as transfers between Level 1 and Level 2 of the fair value hierarchy. The update will be effective for us in the first quarter of Fiscal 2012. It will primarily impact our disclosures, and is not expected to have a material impact on our results of operations, cash flows or financial position.
