Income Tax Disclosure [Abstract]
Income Taxes	Income Taxes The effective income tax rate for continuing operations for the quarter ended November 25, 2018 was 14.3 percent compared to an effective income tax rate of 21.9 percent for the quarter ended November 26, 2017. The effective income tax rate for continuing operations for the six months ended November 25, 2018 was 8.5 percent compared to an effective income tax rate of 23.1 percent for the six months ended November 26, 2017. The decrease in the effective income tax rate for the quarter and six months ended November 25, 2018 was primarily due to the December 2017 enactment of the Tax Cuts and Jobs Act (Tax Act) which reduced the federal corporate income tax rate from 35.0 percent to 21.0 percent. The effective income tax rate for the six months ended November 25, 2018 also decreased due to tax impacts associated with market-driven changes related to our equity-based compensation and tax benefits from stock-option exercises. While we are able to make a reasonable estimate of the impacts of the Tax Act, adjustments may occur and may be affected by other factors, including, but not limited to, further refinement of our calculations, changes in interpretations and assumptions and regulatory changes from the Internal Revenue Service, the SEC, the FASB and various tax jurisdictions. Included in our remaining balance of unrecognized tax benefits is $4.2 million related to tax positions for which it is reasonably possible that the total amounts could change within the next twelve months based on the outcome of examinations or as a result of the expiration of the statute of limitations for specific jurisdictions.
