Income Tax Disclosure [Abstract]
Income Taxes	Income Taxes Our effective tax rate for the thirteen weeks ended July 2, 2016 was 28.8% compared to (21.8)% for the thirteen weeks ended July 4, 2015. For the twenty-six weeks ended July 2, 2016 and July 4, 2015, our effective tax rate was 32.8% and 75.6%, respectively. Under U.S. accounting rules for income taxes, quarterly effective tax rates may vary significantly depending on the actual operating results in the various tax jurisdictions, as well as changes in the valuation allowance related to the expected recovery of deferred tax assets. The thirteen weeks ended July 2, 2016 included net discrete benefits of approximately $2,294, or 3.0 percentage points of the effective tax rate, primarily driven by a net change in valuation allowances against the deferred tax assets of two of our foreign operating units as well as the release of unrealized tax benefits due to the expiration of statute of limitations in various jurisdictions. The thirteen weeks ended July 4, 2015 included net discrete expenses of approximately $12,134, or (43.1) percentage points of the effective tax rate, which primarily related to a $14,580 increase to the valuation allowance on foreign tax credits. The additional valuation allowance recognized in 2015 was a result of a decrease in projected foreign source income, primarily lower royalties from foreign affiliates, due to the decision to cancel future deployments of SAP, partially offset by net discrete benefit of $2,446 primarily driven by the release of unrealized tax benefits due to the expiration of the statute of limitations in various tax jurisdictions. See Note 1 - "Impairment of Internally Developed Software" for additional information on the cancellation of the global SAP deployment. The twenty-six weeks ended July 2, 2016 included net discrete benefits of approximately $2,388, or 2.8 percentage points of the effective tax rate. The twenty-six weeks ended July 4, 2015 included net discrete expenses of approximately $11,525, or(31.3) percentage points of the effective tax rate. Our effective tax rate differed from the U.S. federal statutory rate of 35% during these periods primarily due to the items noted above, as well as the relative mix of earnings or losses within the tax jurisdictions in which we operate, such as: (a) earnings in lower-tax jurisdictions for which no U.S. taxes have been provided because such earnings are planned to be reinvested indefinitely outside the United States; (b) losses in certain jurisdictions in which we are not able to record a tax benefit; and (c) changes in the valuation allowance on deferred tax assets. At July 2, 2016, we had gross unrecognized tax benefits of $23,415 compared to $23,445 at January 2, 2016, representing a net decrease of $30 during the twenty-six weeks ended July 2, 2016. Substantially all of the gross unrecognized tax benefits, if recognized, would impact our effective tax rate in the period of recognition. We recognize interest and penalties related to unrecognized tax benefits in income tax expense. In addition to the gross unrecognized tax benefits identified above, the interest and penalties recorded to date by us totaled $6,296 and $6,652 at July 2, 2016 and January 2, 2016, respectively. Our future effective tax rate will continue to be affected by changes in the relative mix of taxable income and losses in the tax jurisdictions in which we operate, changes in the valuation of deferred tax assets, or changes in tax laws or interpretations thereof. In addition, our income tax returns are subject to continuous examination by the IRS and other tax authorities. The IRS has concluded its examinations of tax years prior to 2012. It is possible that within the next twelve months, ongoing tax examinations in the United States and several of our foreign jurisdictions may be resolved, that new tax exams may commence and that other issues may be effectively settled. However, we do not expect our assessment of unrecognized tax benefits to change significantly over that time.
