Income Tax Disclosure [Abstract]
Income Taxes	Income Taxes The effective income tax rate was 18.1% for the quarter ended June 27, 2018 and 17.1% for the two quarters ended June 27, 2018 compared to 36.0% and 36.1%, respectively, for the prior year periods. The 2018 periods were impacted by the Tax Act. In addition, the 2018 quarterly and year-to-date rates benefited from a discrete item relating to share-based compensation of 5.2% and 4.6%, respectively. The Tax Act reduces the U.S. statutory tax rate from 35% to 21% for years after 2017. We revalued our deferred taxes during fiscal 2017 to reflect the reduced rate that will apply in future periods when these deferred taxes are realized. The implementation of the Tax Act resulted in certain stranded tax effects in accumulated other comprehensive income. Due to the immateriality of the stranded tax effects, we have elected not to reclassify these amounts from accumulated other comprehensive income to retained earnings.
