Income Taxes	3 Months Ended
Jul. 01, 2018
Income Tax [Abstract]
Income Tax Disclosure [Text Block]	Income Taxes We are subject to U.S. federal income tax as well as income tax of multiple state jurisdictions. The tax years prior to our fiscal year ended April 3, 2016 are closed to examination by the Internal Revenue Service. For state and local income tax jurisdictions, the tax years prior to our fiscal year ended March 29, 2015 are closed to examination, with few exceptions. Our effective tax rate for the three months ended July 1, 2018 was 27.3%, compared to an effective tax rate of 38.5% for the three months ended July 2, 2017. The effective tax rate is impacted by projected levels of annual taxable income, permanent items, and state taxes. The decrease in the effective tax rate from the prior year resulted from impacts of the U.S. Tax Cuts and Jobs Act (the “Tax Act”) enacted in December 2017, which reduced the U.S. corporate tax rate from 35% to 21%, offset slightly by the elimination of the domestic manufacturing deduction. Under GAAP, deferred tax assets and liabilities are required to be revalued during the period in which the new tax legislation is enacted. As such, during the fiscal year-end ended April 1, 2018 we revalued our net deferred tax liabilities to reflect the impact of the Tax Act and recorded a one-time benefit of $13.9 million. Pursuant to ASU 2018-05 (regarding the application of ASC 740 associated with the enactment of the Tax Act), the tax benefit we recorded in fiscal year 2018 was provisional. The final impact of the Tax Act may differ due to and among other things, changes in interpretations, assumptions made by the Company and the issuance of additional guidance that may be provided. Specifically, no adjustment was recorded related to the impact of the Tax Act on state taxes, as we could not reasonably estimate the impact and do not expect any such impact to be material to our financial statements. There have been no changes to the provisional amounts recorded during fiscal 2018 in the three months ended July 1, 2018 and we have not finalized our accounting for the impact of the Tax Act. As of July 1, 2018 and April 1, 2018, our balance sheet included a long-term liability for uncertain tax positions of $0.2 million, which arose from tax positions taken by Stauber on its tax returns for periods prior to our acquisition. Because the Stauber acquisition agreement provides us with indemnification by the prior owners for any tax liabilities relating to pre-acquisition tax returns, we have also recorded an offsetting, long-term receivable of $0.2 million as of July 1, 2018 and April 1, 2018. As a result, any change in the unrecognized tax benefit will not impact our effective tax rate in future periods. We expect these uncertain income tax amounts to decrease through September 2019 as the applicable examination periods for the relevant taxing authorities expire.
