Income Tax Disclosure [Abstract]
Income Taxes	NOTE 8. INCOME TAXES Our effective tax rate for the three months ended March 30, 2018, was 16.5% as compared to 26.7% for the three months ended March 31, 2017. The year-over-year decrease was due primarily to favorable impacts in 2018 resulting from a lower statutory tax rate in the United States as a result of the Tax Cuts and Jobs Act (“TCJA”) as well as other federal and international tax benefits. Our effective tax rates for 2018 and 2017 differ from the U.S. federal statutory rate of 21% and 35%, respectively, due primarily to our earnings outside the United States that are indefinitely reinvested and taxed at rates lower than the U.S. federal statutory rate, the impact of credits and deductions provided by law, and the effect of favorable adjustments to the provisional estimates recorded in 2017 related to the TCJA as permitted under SEC Staff Accounting Bulletin No. 118 (“SAB 118”). The adjustments recorded to our provisional estimates decreased income tax expense by $4.2 million during the three months ended March 30, 2018. We will continue to evaluate the effects of the TCJA on the 2017 provisional estimates through the end of the SAB 118 allowable measurement period. Refer to Note 11 of our 2017 Annual Report on Form 10-K for further details including disclosures pursuant to SAB 118 interpretive guidance, including provisional estimates for all TCJA effects. On January 1, 2018, we adopted ASU No. 2016-16, Income Taxes (Topic 715): Intra-entity Transfers of Assets Other Than Inventory using the modified retrospective method, and recorded an immaterial adjustment to opening retained earnings as of January 1, 2018.
