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 of 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, 2013, was reinstated as part of the Tax Increase Prevention Act of 2014, enacted on December 19, 2014. This legislation retroactively reinstated and extended the credit from the previous expiration date through December 31, 2014. The Company recognized a $1.9 million benefit for this credit in the three months ended December 28, 2014. 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 29, 2014, the Company's liability for unrecognized tax benefits was $18.4 million. During the six months ended December 28, 2014, there was a $0.2 million decrease to the amount of unrecognized tax benefits following statute expirations. As a result, the total liability for unrecognized tax benefits as of December 28, 2014 was $18.2 million. If any portion of this $18.2 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 an immaterial amount of gross unrecognized tax benefits will change in the next 12 months. 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 2010. For foreign purposes, the Company is generally no longer subject to tax examinations for tax periods 2004 and prior. Certain carryforward tax attributes generated in prior years remain subject to examination and adjustment. During the second quarter of fiscal 2015, the Company settled its examination with the French Tax Administration for the fiscal year ended June 26, 2011 (fiscal 2011) through the fiscal year ended June 29, 2014 (fiscal 2014), resulting in no additional tax expense.
