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 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. The income tax provision in the second quarter of fiscal 2019 and fiscal 2018 of $0.2 million and $0.6 million, respectively, were primarily related to locations outside of the United States. For the six months ended April 28, 2019, the income tax provision of $0.5 million was primarily related to locations outside of the United States. The income tax benefit in the first six months ended April 29, 2018 of $0.7 million included the reversal of reserves on uncertain tax provisions that expired. 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 reduced the U.S. statutory tax rate from 35.0% to 21.0% effective January 1, 2018. U.S. tax law required 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 was 23.4%. The Company's statutory rate is 21.0% for the fiscal year ended November 3, 2019. Other provisions now effective under the Tax Act include limitations on deductibility of executive compensation and interest, as well as a new minimum tax on Global Intangible Low-Taxed Income (“GILTI”). The Company has analyzed these provisions and there will be no material impact due to the Company's net operating loss carry-forward and valuation allowance. The Company did not record any change to its U.S. net deferred tax balances as of the enactment date since its U.S. net deferred tax assets are fully offset by a full valuation allowance. The Company reduced its net deferred tax assets and corresponding valuation allowance by approximately $26.8 million for the fiscal year ended October 28, 2018. Under the Tax Act, the Company may be subject to a transition tax on the untaxed foreign earnings of its foreign subsidiaries by deeming those earnings to be repatriated (“Transition Tax”). 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 Transition Tax did not have a material impact on the Company.
