Income Tax Disclosure [Abstract]
Income Taxes	Income Taxes The Company recorded a tax provision of $26.0 million for the first quarter of fiscal 2014 as compared to $25.1 million in the same prior year period, representing effective tax rates of 14% and 16%, 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. For the period ended June 29, 2013, there was a decrease in current deferred tax assets, an increase in current deferred tax liabilities and a decrease in long-term deferred tax liabilities primarily related to the reclassification of the Company's debentures from long-term liabilities and additional paid-in capital to current liabilities and temporary equity. See "Note 10. Convertible Debentures and Revolving Credit Facility" for further disclosure of the underlying changes. In addition, there was a significant U.S. federal tax payment which reduced income taxes payable. The Company’s total gross unrecognized tax benefits as of June 29, 2013, determined in accordance with FASB authoritative guidance for measuring uncertain tax positions, was $70.1 million. The total amount of unrecognized tax benefits that, if realized in a future period, would favorably affect the effective tax rate was $33.1 million as of June 29, 2013. 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 Company recorded a tax provision of $26.0 million for the first quarter of fiscal 2014 as compared to $25.1 million in the same prior year period, representing effective tax rates of 14% and 16%, 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.

For the period ended June 29, 2013, there was a decrease in current deferred tax assets, an increase in current deferred tax liabilities and a decrease in long-term deferred tax liabilities primarily related to the reclassification of the Company's debentures from long-term liabilities and additional paid-in capital to current liabilities and temporary equity.

The Company’s total gross unrecognized tax benefits as of June 29, 2013, determined in accordance with FASB authoritative guidance for measuring uncertain tax positions, was $70.1 million. The total amount of unrecognized tax benefits that, if realized in a future period, would favorably affect the effective tax rate was $33.1 million as of June 29, 2013.
