Income Tax Disclosure [Abstract]
Income Taxes	Income Taxes In general, the variation between the Company's effective income tax rate and the U.S. statutory rate of 21% 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. In December 2017, the SEC staff issued Staff Accounting Bulletin 118 (SAB 118), which provides guidance on accounting for the tax effects of the Tax Cuts and Jobs Act of 2017 (Tax Legislation), which was enacted on December 22, 2017. SAB 118 provides a measurement period that should not extend beyond one year from the Tax Legislation enactment date for companies to complete the accounting under ASC Topic 740-Income Taxes. The Company has recorded the income tax effects of the Tax Legislation. The Company considers the following recorded effects to be complete; its re-measurement of deferred taxes, the impact on the realizability of the U.S. deferred tax assets, and withholding and other taxes on future repatriation of cash. The Company considers all other recorded effects to be provisional. These provisional tax effects may differ during the measurement period, possibly materially, due to further refinement of the calculations, changes in interpretations and assumptions made, and additional guidance that may be issued by the Department of the U.S. Treasury, the Internal Revenue Service, and other regulatory and standard setting bodies. The Company will complete its analysis within fiscal 2019 consistent with the guidance provided in SAB 118, and any adjustments during this measurement period will be included in net earnings from continuing operations as an adjustment to income tax expense in the reporting period when such adjustments are determined. No such adjustments were included in income tax expense for the three months ended September 23, 2018. 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. As of June 24, 2018, the U.S. valuation allowance was $122.2 million. During the three months ended September 23, 2018, the Company decreased the U.S. valuation allowance by $26.1 million due to the deferred tax impact of the Notes issuance. As of June 24, 2018, the Luxembourg valuation allowance was $5.2 million. During the three months ended September 23, 2018, the Company increased this valuation allowance by $2.4 million due to year-to-date loss 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 24, 2018, the Company's liability for unrecognized tax benefits was $8.7 million. During the three months ended September 23, 2018, 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 23, 2018 was $8.7 million. If any portion of this $8.7 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 $0.8 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 2015. For U.S. state tax returns, the Company is generally no longer subject to tax examinations for fiscal years prior to 2014. For foreign purposes, the Company is generally no longer subject to examination for tax periods prior to 2008. Certain carryforward tax attributes generated in prior years remain subject to examination, adjustment and recapture.
