Income Tax Disclosure [Abstract]
Income Taxes	INCOME TAXES Our income tax provision or benefit for interim periods is determined using an estimate of our annual effective tax rate, adjusted for discrete items, if any, that are taken into account in the relevant period. Each quarter we update our estimate of the annual effective tax rate, and if our estimated tax rate changes we make a cumulative adjustment. Our quarterly tax provision and quarterly estimate of our annual effective tax rate are subject to variation due to several factors, including variability in accurately predicting our pre-tax and taxable income and loss by jurisdiction, tax credits, government audit developments, changes in laws, regulations and administrative practices, and relative changes in expenses or losses for which tax benefits are not recognized. Additionally, our effective tax rate can be more or less volatile based on the amount of pre-tax income. For example, the impact of discrete items, tax credits, and non-deductible expenses on our effective tax rate is greater when our pre-tax income is lower. Our effective tax rate for the thirty-nine weeks ended September 30, 2018 was 12.2%. The difference between the statutory federal income tax rate of 21.0% and our effective income tax rate results primarily from the federal Work Opportunity Tax Credit. This tax credit is designed to encourage employers to hire workers from certain targeted groups with higher than average unemployment rates. Other differences between the statutory federal income tax rate of 21.0% and our effective tax rate result from state and foreign income taxes, certain non-deductible expenses, tax exempt interest, and tax effects of share based compensation. On December 22, 2017, Staff Accounting Bulletin No. 118 was issued to address the application of U.S. GAAP in situations when a registrant does not have the necessary information available, prepared, or analyzed in reasonable detail to complete the accounting for income tax effects of the Tax Cuts and Jobs Act (the “Tax Act”). For the thirty-nine weeks ended September 30, 2018, we completed accounting for the Tax Act by recording immaterial adjustments to our transition tax and revaluation of net deferred tax assets at December 31, 2017. We also determined that unremitted earnings of our foreign subsidiaries should no longer remain subject to an indefinite reinvestment assertion and recorded a $0.4 million deferred tax liability related to foreign withholding taxes.
