Income Tax Disclosure [Abstract]
Income Taxes	Income Taxes The Company recorded tax provisions of $12.0 million and $51.8 million for the third quarter and the first nine months of fiscal 2013, respectively, representing effective tax rates of 10% and 13%, respectively. The rate for the third quarter of fiscal 2013 included a net discrete benefit of $5.3 million relating primarily to lapses of statutes of limitation. The Company recorded tax provisions of $2.9 million and $49.0 million for the third quarter and the first nine months of fiscal 2012, respectively, representing effective tax rates of 2% and 11%, respectively. The rate for the third quarter of fiscal 2012 included a net discrete benefit of $15.3 million relating primarily to lapses of statutes of limitation. The difference between the U.S. federal statutory tax rate of 35% and the Company’s effective tax rate in all periods is primarily due to income earned in lower tax rate jurisdictions, for which no U.S. income tax has been provided, as the Company intends to permanently reinvest these earnings outside of the U.S. The Company’s total gross unrecognized tax benefits as of December 29, 2012, determined in accordance with FASB authoritative guidance for measuring uncertain tax positions, decreased by $7.3 million in the third quarter of fiscal 2013 to $57.5 million. The decrease was primarily attributable to lapses of statutes of limitation. The total amount of unrecognized tax benefits that, if realized in a future period, would favorably affect the effective tax rate was $25.8 million as of December 29, 2012. It is reasonably possible that changes to our unrecognized tax benefits could be significant in the next twelve months due to tax audit settlements and lapses of statutes of limitation. As a result of uncertainties regarding tax audit settlements and their possible outcomes, an estimate of the range of increase or decrease that could occur in the next twelve months cannot be made. The Company's policy is to include interest and penalties related to income tax liabilities within the provision for income taxes on the consolidated statements of income. The balances of accrued interest and penalties recorded in the condensed consolidated balance sheets and the amounts of interest and penalties included in the Company's provisions for income taxes were not material for any period presented. The Company is no longer subject to U.S. federal audits by taxing authorities for years through fiscal 2009. The Company is no longer subject to U.S. state audits for years through fiscal 2004, except for fiscal years 1996 through 2001 which are still open for audit purposes.
