Income Tax Disclosure [Abstract]
Income Taxes	Income Taxes: The Company’s effective income tax rate decreased to 21.5% in the third quarter of fiscal 2018 compared to 36.4% for the third quarter of fiscal 2017. The decrease was primarily due to the effect of the TCJA, which was signed into law in December 2017 and, to a lesser extent, an incremental tax benefit associated with share-based compensation compared to the third quarter of 2017. For the first nine months of fiscal 2018, the Company’s effective income tax rate decreased to 22.1% compared to 36.5% for the first nine months of fiscal 2017. The decrease in the effective income tax rate was primarily due to the effect of the TCJA. In addition, income taxes were further reduced by the realization of discrete federal and state tax credits and an incremental tax benefit associated with share-based compensation. Under the provisions of the TCJA, the U.S. corporate federal income tax rate decreased from 35% to 21% effective for tax years beginning after December 31, 2017. The Company made a reasonable estimate of the effects on our existing deferred tax balances as of December 30, 2017, and recognized a provisional expense amount of $4.9 million, which was included as a component of income tax expense from continuing operations for fiscal 2017. The Company will recognize any changes to this provisional amount as we refine our estimates of our cumulative temporary differences and interpretations of guidance related to the application of the TCJA.
