Income Tax Disclosure [Abstract]
Income Taxes	Income Taxes The variation between the Company's effective income tax rate and the U.S. statutory rate of 35% is due to the impact of the Company’s pre-tax income or loss relative to favorable tax rate impacts associated predominantly with the Company’s: (i) projected income for the full year derived from international locations with lower tax rates than the U.S. and (ii) projected tax credits generated. Tax credits and other deductions have the impact of increasing the tax rate above the statutory rate of 35% in periods in which the Company reports pre-tax losses as they provide a benefit that is recoverable in future periods. U.S. GAAP requires a two-step approach to recognizing and measuring uncertain tax positions. The first step is to evaluate the tax position for recognition by determining if the weight of available evidence indicates that it is more likely than not that the position will be sustained on audit, including resolution of related appeals or litigation processes, if any. The second step is to measure the tax benefit as the largest amount that is cumulatively more than 50% likely to be realized upon ultimate settlement. As of June 26, 2016, the Company's liability for unrecognized tax benefits was $17.7 million. During the three months ended September 25, 2016, the Company did not record any material movement in its unrecognized tax benefits. As a result, the total liability for unrecognized tax benefits as of September 25, 2016 was $17.7 million. If any portion of this $17.7 million is recognized, the Company will then include that portion in the computation of its effective tax rate. Although the ultimate timing of the resolution and/or closure of audits is highly uncertain, the Company believes it is reasonably possible that $4.3 million of gross unrecognized tax benefits will change in the next 12 months as a result of audit closures and statute requirements. The Company files U.S. federal, U.S. state and foreign tax returns. For U.S. federal purposes, the Company is generally no longer subject to tax examinations for fiscal years prior to 2013. For U.S. state tax returns, the Company is generally no longer subject to tax examinations for fiscal years prior to 2012. For foreign purposes, the Company is generally no longer subject to tax examinations for tax periods 2006 and prior. Certain carryforward tax attributes generated in prior years remain subject to examination, adjustment and recapture. The Company is currently under audit by the Italian Revenue Agency for the fiscal year ended June 30, 2013. During the fourth quarter of fiscal 2016, the Company concluded it is likely that sufficient future taxable income needed to fully utilize net operating loss carryovers in Luxembourg will not be generated due to additional losses on the Company’s equity investment held there. The Company recorded a $9.5 million valuation allowance against the related deferred tax asset, representing the $32.4 million net operating loss carryover net of tax. During the three months ended September 25, 2016, the Company recorded an additional $0.3 million valuation allowance against the loss carryover deferred tax asset as a result of the $1.1 million year-to-date loss on the equity investment held in Luxembourg.
