Income Tax Disclosure [Abstract]
Income Taxes	Income Taxes The Company’s effective tax rate for the three months ended March 31, 2019 and April 1, 2018 was 20.0% and (40.5)% respectively. The Company’s effective tax rate varies from the U.S. federal statutory rate of 21% primarily due to (1) net excess tax benefits related to share-based payments, which resulted in a benefit of $2,036 in the first quarter of 2019 and a benefit of $6,093 for the first quarter of 2018, (2) the impact of the comprehensive tax legislation commonly referred to as the Tax Cuts and Jobs Act (the “Tax Act”) and (3) state income tax provision in 2019, including non-recurring changes to state deferred taxes net of federal benefits. On December 22, 2017, the U.S. government enacted the Tax Act. In our continued analysis of the impact of the Tax Act in the first quarter of 2018 under Staff Accounting Bulletin 118, we adjusted our provisional amounts for a discrete net tax benefit of $3,623. This net benefit included $5,578 for the tax benefit of foreign tax credits, partially offset by a net expense of $1,955 related to the impact of the corporate rate reduction on our net deferred tax liabilities. There were no significant changes to the unrecognized tax benefits or related interest and penalties for the three months ended March 31, 2019. During the next twelve months, we believe it is reasonably possible the Company will reduce unrecognized tax benefits by up to $7,764 due to the lapse of statutes of limitations and expected settlements with taxing authorities. The current portion of refundable income taxes was $9,560 and $14,475 as of March 31, 2019 and December 30, 2018, respectively, and is included in “Accounts and notes receivable, net” in the condensed consolidated balance sheets. There were no long-term refundable income taxes as of March 31, 2019 and December 30, 2018.
