Income Tax Disclosure [Abstract]
Income Taxes	Income Taxes As of March 29, 2015, the total gross liability for income taxes associated with uncertain tax positions was approximately $40.2 million. If fully recognized, approximately $26.5 million of the $40.2 million would impact the Company’s effective tax rate. The Company cannot make a reasonably reliable estimate of the period of payment for this liability. Absent any resolution of the on-going audit by the Internal Revenue Service (IRS) discussed below, the Company does not expect that the liability for unrecognized tax benefits will change significantly within the next 12 months. The Company’s federal income tax returns for fiscal years 2008 to 2013 and California income tax returns for fiscal years 2008 to 2013 are open as the statutes of limitations have not yet expired or have been extended. The Company's federal income tax returns for fiscal 2010 to 2013 are currently under examination by the IRS. Additionally, the Company’s California income tax returns for fiscal years 2008 and 2009 are currently under examination by the California Franchise Tax Board. The Company is also currently under audit by various state and international taxing authorities. In foreign jurisdictions, with few exceptions, the Company is subject to examinations for all years subsequent to fiscal 2010. The Company does not expect any audits for these foreign jurisdictions to have a material effect on the results of operations or financial position. The IRS completed its examination of the Company’s federal income tax returns for fiscal years 2008 and 2009 and the amended return filed for fiscal year 2007 and issued a 30-Day Letter in March 2014. In the 30-Day Letter, the IRS proposed adjustments related to the amount of "buy-in-payments" made by one of the international subsidiaries to the Company in connection with the cost-share agreement entered into by the Company and its international subsidiary in fiscal year 2008.

As of March 29, 2015, the total gross liability for income taxes associated with uncertain tax positions was approximately $40.2 million. If fully recognized, approximately $26.5 million of the $40.2 million would impact the Company’s effective tax rate. The Company cannot make a reasonably reliable estimate of the period of payment for this liability. Absent any resolution of the on-going audit by the Internal Revenue Service (IRS) discussed below, the Company does not expect that the liability for unrecognized tax benefits will change significantly within the next 12 months.

The Company’s federal income tax returns for fiscal years 2008 to 2013 and California income tax returns for fiscal years 2008 to 2013 are open as the statutes of limitations have not yet expired or have been extended.
