Income Tax Disclosure [Abstract]
Income Taxes	Income Taxes The income tax provision 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 Accounting Standards Codification (“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 third quarter of fiscal 2018 and fiscal 2017, income taxes were a provision of $1.3 million and $1.1 million, respectively. For the nine months ended July 29, 2018 and July 30, 2017, income taxes were a provision of $0.6 million and $0.9 million, respectively. The income tax provision in the nine months ended July 29, 2018 and July 30, 2017 included a reversal of reserves on uncertain tax provisions of $1.1 million and $1.3 million, respectively. The Company’s quarterly provision (benefit) for income taxes is measured using an estimated annual effective tax rate, adjusted for discrete items that occur within the periods presented. On December 22, 2017, the U.S. President signed the Tax Cuts and Jobs Act (“Tax Act”) into law. The Tax Act includes a number of provisions, including the lowering of the U.S. corporate tax rate from 35.0% to 21.0%, and the establishment of a territorial-style system for taxing foreign-source income of domestic multinational corporations. The Tax Act reduces the U.S. statutory tax rate from 35.0% to 21.0% effective January 1, 2018. U.S. tax law requires that taxpayers with a fiscal year that begins before and ends after the effective date of a rate change calculate a blended tax rate based on the pro-rata number of days in the fiscal year before and after the effective date. As a result, for the fiscal year ending October 28, 2018, the Company’s statutory income tax rate will be approximately 23.4%. The SEC staff issued Staff Accounting Bulletin ("SAB") 118, which provides guidance on accounting for the tax effects of the Tax Act. SAB 118 provides a measurement period that should not extend beyond one year from the Tax Act enactment date for companies to complete the accounting under ASC 740. In accordance with SAB 118, a company must reflect the income tax effects of those aspects of the Tax Act for which the accounting under ASC 740 is complete. To the extent that a company’s accounting for certain income tax effects of the Tax Act is incomplete but it is able to determine a reasonable estimate, it must record a provisional estimate in the financial statements. If a company cannot determine a provisional estimate to be included in the financial statements, it should continue to apply ASC 740 on the basis of the provisions of the tax laws that were in effect immediately before the enactment of the Tax Act. The Company does not anticipate any material impact on recorded deferred tax balances as the remeasurement of our U.S. net deferred tax assets is offset by a corresponding change in valuation allowance. In connection with our continued analysis of the impact of the Tax Act, the Company does not have any change to its net deferred tax assets and corresponding valuation allowance for the three months ended July 29, 2018 and reduced its net deferred tax assets and corresponding valuation allowance by $25.4 million for the nine months ended July 29, 2018. The Tax Act also imposes a transition tax on the untaxed foreign earnings of foreign subsidiaries of U.S. companies by deeming those earnings to be repatriated. The Company is currently evaluating the effect of the transition tax on our non-U.S. earnings. Foreign earnings held in the form of cash and cash equivalents are taxed at a 15.5% rate and the remaining earnings are taxed at an 8.0% rate. In calculating the transition tax, the Company must calculate the cumulative earnings and profits of each of the non-U.S. subsidiaries back to 1987. The Company expects to complete this calculation and record any tax due by the end of fiscal 2018. Based on a preliminary analysis, and as a result of the Company’s significant tax attributes, the Company does not expect to have any amount due related to the transition tax. The Company will continue to analyze the effects of the Tax Act on its financial statements and operations. Any additional impacts of the Tax Act will be recorded as they are identified during the measurement period in accordance with SAB 118.
