Income Tax Disclosure [Abstract]
Income Taxes	Income Taxes In connection with a current examination of the tax returns in two foreign jurisdictions, the taxing authorities have issued income tax deficiencies related to transfer pricing aggregating approximately $144.1 million (including interest and penalties) for tax years 2012 through 2016. We strongly disagree with the proposed adjustments and have filed a protest with each of the taxing authorities as we believe that the proposed adjustments are without technical merit. We will continue to vigorously contest the adjustments and expect to exhaust all administrative and judicial remedies necessary to resolve the matters, which could be a lengthy process. We regularly assesses the likelihood of adverse outcomes resulting from examinations such as these to determine the adequacy of our tax reserves. Accordingly, we have not accrued any additional amounts based upon the proposed adjustments. There can be no assurance that these matters will be resolved in our favor, and an adverse outcome of either matter, or any future tax examinations involving similar assertions, could have a material effect on our financial condition, results of operations and cash flows. On December 22, 2017, the Tax Cut and Jobs Act (the "Act") was signed into law. In accordance with Staff Accounting Bulletin (“SAB”) 118, we recognized the estimated impact of this legislation as a component of income tax expense in our audited financial statements for the year ending December 29, 2017. SAB 118 allows for a measurement period, not to extend beyond one year from the enactment date, for companies to complete their accounting for the provisions of the Act under ASC 740. As of September 28, 2018, we finalized our analysis of the impact of the Act and determined that there were no adjustments required to be recorded for the financial statement for the year ending December 29, 2017.
