Income Tax Disclosure [Abstract]
Income Taxes	Income Taxes Our effective tax rate for the thirteen weeks ended July 4, 2015 was (21.8)% compared to 34.2% for the thirteen weeks ended June 28, 2014. For the twenty-six weeks ended July 4, 2015 and June 28, 2014, our effective tax rate was 75.6% and 37.6%, 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 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 is 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 4, 2015 included net discrete expenses of approximately $11,525, or 31.3 percentage points of the effective tax rate, and the twenty-six weeks ended June 28, 2014 included net discrete benefits of approximately $2,525, or 2.1 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 4, 2015, we had gross unrecognized tax benefits of $28,810 compared to $30,372 at January 3, 2015, representing a net decrease of $1,562 during the twenty-six weeks ended July 4, 2015. 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 $7,168 and $7,625 at July 4, 2015 and January 3, 2015, 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 tax year 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.
