Income Tax Disclosure [Abstract]
INCOME TAXES	INCOME TAXES Our tax provision or benefit from income taxes 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 our 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 and the mix of jurisdictions to which they relate, tax credits, audit developments, changes in law, regulations and administrative practices, and relative changes of 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. Except as required under U.S. tax law, we do not provide for U.S. taxes on undistributed earnings of our foreign subsidiaries since we consider those earnings to be permanently invested outside of the U.S. Our effective tax rate for the thirty-nine weeks ended September 23, 2016 was 22.9%. The principal difference between the statutory federal income tax rate of 35.0% and our effective income tax rate of 22.9% results from non-deductible goodwill impairment and the estimated 2016 federal Work Opportunity Tax Credit ("WOTC"). In December of 2015, WOTC was restored through 2019 as a result of the Protecting Americans from Tax Hikes Act of 2015. We recognized $5.6 million of discrete tax benefits from prior year WOTC. We also recognized $17.7 million of discrete tax detriment from non-deductible goodwill impairment. Other differences between the statutory federal income tax rate of 35.0% and our effective tax rate of 22.9% result from state and foreign income taxes and certain non-deductible expenses. Our effective tax rate on earnings for the thirty-nine weeks ended September 25, 2015, was 32.2%. The principal difference between the statutory federal income tax rate of 35.0% and our effective income tax rate of 32.2% results from estimated WOTC earned in 2015 from 2014 hires. WOTC had expired for 2015 hires. We also recognized $3.7 million of discrete tax benefits from prior year WOTC and California Enterprise Zone tax credits. Other differences between the statutory federal income tax rate of 35.0% result from state and foreign income taxes and certain non-deductible expenses. As of September 23, 2016 and December 25, 2015, we had gross unrecognized tax benefits of $2.2 million recorded in accordance with current accounting guidance on uncertain tax positions.
