Income Tax Disclosure [Abstract]
Income Taxes	Income Taxes The Company recorded tax provisions of $22.8 million and $49.5 million for the second quarter and the first six months of fiscal 2015, respectively, representing effective tax rates of 12% and 13%, respectively. The Company recorded tax provisions of $11.3 million and $37.3 million for the second quarter and the first six months of fiscal 2014, respectively, representing effective tax rates of 7% and 11%, respectively. 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 September 27, 2014, determined in accordance with FASB authoritative guidance for measuring uncertain tax positions, was $26.4 million. The total amount of unrecognized tax benefits that, if realized in a future period, would favorably affect the effective tax rate was $11.0 million as of September 27, 2014. 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 condensed consolidated statements of income. The balance of accrued interest and penalties recorded in the condensed consolidated balance sheets and the amounts of interest and penalties included in the Company's provision for income taxes were not material for all periods presented. The Company is no longer subject to U.S. federal audits by taxing authorities for years through fiscal 2010.
