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 a percentage of the Company's projected income for the full year being derived from international locations with lower tax rates than the U.S. and the impact of tax credits available in the current year. A change in the mix of pretax income in the Company's various tax jurisdictions can have a material impact on the Company's periodic effective tax rate. The research and development credit, which had previously expired on December 31, 2014, was reinstated as part of the Protecting Americans from Tax Hikes Act of 2015, enacted on December 18, 2015. This legislation retroactively reinstated and permanently extended the research and development credit. The Company recognized a $1.8 million benefit for this credit in the three months ended December 27, 2015, which was primarily a catch-up benefit for second half of fiscal 2015 and the first quarter of fiscal 2016. 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 28, 2015, the Company's liability for unrecognized tax benefits was $17.8 million. During the six months ended December 27, 2015, the Company recognized a $0.6 million increase to the liability for unrecognized tax benefits due to uncertainty regarding intercompany transactions recently challenged by the Italian tax authority. As a result, the total liability for unrecognized tax benefits as of December 27, 2015 was $18.4 million. If any portion of this $18.4 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 $0.2 million of gross unrecognized tax benefits will change in the next 12 months as a result of 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 2012. For U.S. state tax returns, the Company is generally no longer subject to tax examinations for fiscal years prior to 2011. For foreign purposes, the Company is generally no longer subject to tax examinations for tax periods 2005 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.
