Income Tax Disclosure [Abstract]
Income Taxes	Note 9 – Income Taxes The effective income tax rate was 27.7% and 32.8% for the first quarter and the prior year quarter, respectively. The differences from the federal statutory rates of 21% and 35% for the first quarter and the prior year quarter, respectively, are primarily due to state income taxes and stock-based compensation. On December 22, 2017, the U.S. government enacted comprehensive tax legislation commonly referred to as the Tax Cuts and Jobs Act (the “Tax Act”). The Tax Act made broad and complex changes to the U.S. tax code, including, but not limited to reducing the U.S. federal corporate tax rate from 35 percent to 21 percent, effective January 1, 2018. In connection with initial analysis of the impact of the Tax Act, the Company recorded a provisional discrete income tax benefit of $26.0 million in the period ended December 30, 2017 associated with the re-measurement of deferred tax assets and liabilities as a result of the reduction in the U.S. federal corporate tax rate. The Company has not completed its accounting for the income tax effects of certain elements of the Tax Act, but recorded provisional adjustments based on reasonable estimates, which have not materially changed since December 30, 2017. Those estimates may be impacted by the need for further analysis and future clarification and guidance regarding available tax accounting methods and elections, state tax conformity to federal tax changes and expected changes to U.S. Treasury regulations. The Company anticipates these estimates will be finalized on or before the due date of the federal return, which is October 15, 2018.
