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 28.3% is primarily due to: (i) changes in the Company’s valuation allowances against deferred tax assets in the U.S. and Luxembourg, (ii) projected income for the full year derived from international locations with lower tax rates than the U.S. and (iii) projected tax credits generated. The Tax Cuts and Jobs Act of 2017 (Tax Legislation), enacted on December 22, 2017, contains significant changes to U.S. tax law, including lowering the U.S. corporate income tax rate to 21%, implementing a territorial tax system, and imposing a one-time tax on deemed repatriated earnings of foreign subsidiaries. The Tax Legislation reduces the U.S. statutory tax rate from 35% to 21%, effective January 1, 2018. U.S. tax law requires that taxpayers with a fiscal year that begins before and ends after the effective date of a rate change calculate a blended tax rate based on the pro rata number of days in the fiscal year before and after the effective date. As a result, for the fiscal year ending June 24, 2018, the Company’s statutory income tax rate will be 28.3%. For the fiscal year ending June 30, 2019, the Company’s statutory income tax rate will be 21%. During the three months ended December 24, 2017, the Company recorded an $18.8 million discrete tax benefit representing the benefit of remeasuring its U.S. deferred tax liabilities at the lower 21% statutory tax rate. The Tax Legislation also implements a territorial tax system. Under the territorial tax system, in general, the Company’s foreign earnings will no longer be subject to tax in the U.S. As part of transitioning to the territorial tax system the Tax Legislation includes a mandatory deemed repatriation of all undistributed foreign earnings that are subject to a U.S. income tax. The Company estimates that the deemed repatriation will result in $15.7 million of additional U.S. income tax which the Company expects to fully offset through the utilization of tax credits. This preliminary estimate may be impacted by a number of additional considerations, including, but not limited to, the issuance of final regulations, the Company's ongoing analysis of the new law and the Company's actual earnings for the fiscal year ending June 24, 2018. As of December 24, 2017, the Company has approximately $280.3 million of undistributed earnings for certain non-U.S. subsidiaries. These undistributed earnings are subject to the one-time deemed repatriation tax, but could be subject to additional foreign and state income taxes if they are repatriated. The Company has historically asserted its intent to reinvest these earnings in foreign operations indefinitely. The Company has reevaluated its historical assertion considering the enactment of the Tax Legislation and determined that $220.8 million of the undistributed foreign earnings are expected to be repatriated in the foreseeable future. During the three months ended December 24, 2017, the Company recorded a $3.0 million discrete tax expense representing the deferred tax liability for foreign income taxes expected to be withheld upon repatriation of the foreign earnings. As of December 24, 2017, the Company has not provided income taxes on the remaining undistributed foreign earnings as the Company continues to maintain its intention to reinvest these earnings in foreign operations indefinitely. If, at a later date, these earnings were repatriated to the U.S., the Company would be required to pay approximately $3.0 million in taxes on these amounts. The Company assesses all available positive and negative evidence to estimate if sufficient future taxable income will be generated to utilize the existing deferred tax assets by jurisdiction. The Company has concluded that it is necessary to recognize a full valuation allowance against its U.S. and Luxembourg deferred tax assets. The Company reassessed the need for a full valuation allowance against its U.S. deferred tax assets due to the Tax Legislation and concluded that a full valuation allowance is still necessary. As of June 25, 2017, the U.S. valuation allowance was $101.8 million. During the six months ended December 24, 2017, the Company reduced the U.S. valuation allowance by $20.0 million as a result of remeasuring its U.S. deferred tax assets at the 21% statutory rate and, as a result, the U.S. valuation allowance is $81.8 million as of December 24, 2017. As of June 25, 2017, the Luxembourg valuation allowance was $5.8 million. During the six months ended December 24, 2017, the Company reduced this valuation allowance by $4.8 million as a result of the $18.4 million year-to-date income in Luxembourg. 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 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 25, 2017, the Company's liability for unrecognized tax benefits was $13.3 million. During the six months ended December 24, 2017, the Company recorded a $4.7 million decrease to the liability for unrecognized tax benefits due to the U.S. statutory rate reduction. In addition, there was a $0.6 million increase in the unrecognized tax benefits due to uncertainty regarding state depreciation deductions. As a result, the total liability for unrecognized tax benefits as of December 24, 2017 was $9.2 million. If any portion of this $9.2 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 $0.4 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 2014. For U.S. state tax returns, the Company is generally no longer subject to tax examinations for fiscal years prior to 2013. For foreign purposes, the Company is generally no longer subject to tax examinations for tax periods prior to 2007. Certain carryforward tax attributes generated in prior years remain subject to examination, adjustment and recapture.
