Income Taxes	3 Months Ended
Mar. 30, 2019
Income Tax Disclosure [Abstract]
Income Taxes	Income Taxes The Company’s effective tax rate for the three months ended March 30, 2019 was 12.2%. The variance from the 2019 federal statutory rate of 21% for the current period was attributable to the benefits of lower tax rates on foreign earnings and U.S. tax credits. These benefits were partially offset by the impacts of foreign earnings taxed in the U.S. and deemed royalties taxed in the U.S. The Company’s effective tax rate also benefited from certain discrete items. The Company’s effective tax rate for the three months ended March 31, 2018 was 18.0%. The variance from the 2018 federal statutory rate of 21% for the prior period was attributable to the benefits of lower tax rates on foreign earnings and U.S. tax credits. These benefits were partially offset by the impacts of foreign earnings taxed in the U.S. and deemed royalties taxed in the U.S. The Company’s effective tax rate also benefited from certain discrete items. The items creating the variances from the U.S. statutory rate to the effective rates of both comparative quarters are similar. However, the lower tax rate for the current quarter is primarily the result of increased foreign pre-tax income taxed at a rate lower than the U.S. statutory rate and discrete tax items. For the three months ended March 30, 2019, and March 31, 2018, foreign earnings taxed in the United States includes the impacts of the Global Intangible Low-Taxed Income, the Deduction for Foreign-Derived Intangible Income, and the Base Erosion Anti-Avoidance Tax (“BEAT”) provisions of the Tax Cuts and Jobs Act, enacted in December, 2017 (“U.S. Tax Reform”, or “the Act”). The Company has included the rate impacts of these provisions in its annual forecasted rate relying on all currently available guidance. It is anticipated that the U.S. Treasury will provide further guidance throughout the year. Pre-tax earnings outside the United States are primarily generated in the United Kingdom, Singapore, and Luxembourg, with statutory rates of 19%, 17%, and 26%, respectively. During 2018, the Company applied for and was granted a second extension of its incentivized tax rate by the Singapore Economic Development Board. The incentive reduces the income tax rate to 10.5% from the statutory rate of 17% and is effective for calendar years 2019 to 2023. The Company has committed to making additional investments in Singapore over the period 2019 to 2022; should the Company not make these investments in accordance with the agreement, any incentive benefit would have to be repaid to the Singapore tax authorities. The Company earns a significant amount of its operating income outside of the U.S. The Company’s policy considers its U.S. investments in directly-owned foreign affiliates to be indefinitely reinvested. As a result of U.S. Tax Reform, future remittance of dividends from foreign subsidiaries to the U.S. parent will generally no longer be subject to U.S. tax when repatriated but may be subject to withholding taxes of the payor affiliate country. Additionally, gains and losses on taxable dispositions of U.S.-owned foreign affiliates continue to be subject to U.S. tax. Quarterly, management evaluates all jurisdictions based on historical pre-tax earnings and taxable income to determine the need for valuation allowances. Based on this analysis, a valuation allowance has been recorded for any jurisdictions where, in the Company’s judgment, tax benefits are not expected to be realized. Uncertain Tax Positions The Company is currently undergoing U.S. federal income tax audits for the tax years 2016 and 2017, as well as a UK income tax audit for fiscal years 2012 through 2014, and 2016. Fiscal years 2004 through 2018 remain open to examination by multiple foreign and U.S. state taxing jurisdictions. The Company anticipates that $22 million of uncertain tax benefits may be settled within the next twelve months and has reflected this liability as current within the Company’s Consolidated Balance Sheets. Due to uncertainties in any tax audit or litigation outcome, the Company’s estimates of the ultimate settlement of uncertain tax positions may change and the actual tax benefits may differ significantly from the estimates.
