Income Tax Disclosure [Abstract]
Income Taxes	Income Taxes The income tax provision (benefit) reflects the geographic mix of earnings in various federal, state and foreign tax jurisdictions and their applicable rates resulting in a composite effective tax rate. The Company’s cumulative results for substantially all United States and certain non-United States jurisdictions for the most recent three-year period is a loss. Accordingly, a valuation allowance has been established for substantially all loss carryforwards and other net deferred tax assets for these jurisdictions, resulting in an effective tax rate that is significantly different than the statutory rate. The Company adjusts its effective tax rate for each quarter to be consistent with the estimated annual effective tax rate, consistent with ASC 270, Interim Reporting, and ASC 740-270, Income Taxes – Intra Period Tax Allocation. Jurisdictions with a projected loss for the full year where no tax benefit can be recognized are excluded from the calculation of the estimated annual effective tax rate. The Company's future effective tax rates could be affected by earnings being different than anticipated in countries with differing statutory rates, increases in recorded valuation allowances of tax assets, or changes in tax laws. The Company's provision (benefit) for income taxes primarily includes foreign jurisdictions and state taxes. In the second quarter of fiscal 2017, income taxes were a benefit of $0.8 million and a provision of $1.1 million in the second quarter of fiscal 2016. For the six months ended April 30, 2017, income taxes were a benefit of $0.1 million and a provision of $1.6 million for the six months ended May 1, 2016. The Company's quarterly income taxes are measured using an estimated annual effective tax rate, adjusted for discrete items that occur within the periods presented. For the quarter ended April 30, 2017, the Company recorded a net discrete tax benefit of approximately $1.3 million resulting from the resolution of uncertain tax positions upon the completion and effective settlement of the audit of the Company’s fiscal 2004 through 2010 federal income tax returns and associated state tax audits. The Company received $13.8 million of federal refunds related to the completion of the audit periods in March 2017. The Company continues to work with the IRS to resolve one remaining matter related to fiscal 2010 and anticipates to have the matter resolved within the next several quarters.
