Income Taxes	Income Taxes The Company’s effective tax rates for the three-month periods ended April 1, 2017 and April 2, 2016 were 500.0% and 33.3%, respectively. The current period variance from the federal statutory rate is attributable to unbenefited foreign losses, benefits of foreign rates, and credits against U.S. income tax offset by the impacts of the Enterprise acquisition and state income taxes. The discrete provision for income taxes recorded in the period results from benefits related to an intercompany sale of intellectual property, benefits from a rate decrease in Singapore, and windfall benefits related to stock compensation. The rate impacts of the intercompany sale, a $12 million benefit, is the result of newly adopted accounting standards. Impacts related to stock compensation newly adopted accounting standards are immaterial in the current period. The prior year variance from statutory rates is the result of foreign income mix and non-taxable interest income. The Company is currently undergoing audits of the 2013 through 2015 U.S. federal income tax returns. The Company is engaged in an inquiry from the UK HM Revenue and Customs for the years 2012 and 2014. The tax years 2004 through 2016 remain open to examination by multiple foreign and U.S. state taxing jurisdictions. Due to uncertainties in any tax audit 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.
