Income Tax Disclosure [Abstract]
Income Taxes	Note 5—Income Taxes Income tax expense was $0.9 million on pre-tax income from continuing operations of $5.5 million for the three months ended March 31, 2018, as compared to an income tax expense of $1.7 million on pre-tax loss from continuing operations of $8.5 million for the three months ended April 1, 2017, respectively. The effective income tax rates were 16.4% and (20.0%) for the three months ended March 31, 2018 and April 1, 2017, respectively. The effective tax rate for the three months ended March 31, 2018 varied from the effective tax rate for the three months ended April 1, 2017 due primarily to losses incurred in the United States for which we have recognized a tax benefit in 2018. On December 22, 2017, the U.S. government enacted the Tax Act, which significantly revised the U.S. corporate income tax regime by, among other things, lowering the U.S. corporate tax rate from 35% to 21%, limiting various business deductions and repealing the corporate alternative minimum tax. Many provisions in the Tax Act are generally effective in tax years beginning after December 31, 2017. GAAP requires the impact of tax legislation to be recognized in the period in which the law was enacted. As a result of the Tax Act, the Company recorded tax benefits in the fourth quarter of 2017 of $32.2 million due to a re-measurement of the U.S deferred tax assets and liabilities and $1.3 million due to the repeal of the corporate alternative minimum tax. The tax benefits represent provisional amounts and our current best estimates. We have not made adjustments to our provisional estimate during the first quarter of 2018. The provisional amounts incorporate assumptions made based upon our current interpretation of the Tax Act and in accordance with SAB 118 may be refined through the fourth quarter of 2018 as we receive additional clarification and implementation guidance. As we finalize the accounting for the tax effects of the enactment of the Tax Act during the measurement period, we will reflect adjustments to the provisional amounts recorded and record additional tax effects in the periods such adjustments are identified.
