Income Tax Disclosure [Abstract]
Income Taxes	Income Taxes Our effective tax rate increased to 20.1% for the first six months ended February 29, 2020 from 18.4% for the first six months ended February 23, 2019 due primarily to the favorable impact in the prior year of research and development tax credits . We file a U.S. Federal tax return, as well as returns in various international and state jurisdictions. As of February 29, 2020, our federal returns from Fiscal 2016 to present are subject to review by the Internal Revenue Service. With limited exception, state returns from Fiscal 2015 to present continue to be subject to review by state taxing jurisdictions. We are currently under review by certain U.S. state tax authorities for Fiscal 2015 through 2018. We believe we have adequately reserved for our exposure to additional payments for uncertain tax positions in our liability for unrecognized tax benefits.
