Income Tax Disclosure [Abstract]
Income Taxes	NOTE 10—INCOME TAXES The Company recorded income tax expense of $2.9 million and $5.6 million in the three months ended August 4, 2018 and July 29, 2017, respectively. The Company recorded income tax expense of $11.4 million and $3.7 million in the six months ended August 4, 2018 and July 29, 2017. The effective tax rate was 4.4% and -245.0% for the three months ended August 4, 2018 and July 29, 2017, respectively. The effective tax rate was 11.1% and -48.5% for the six months ended August 4, 2018 and July 29, 2017. The effective tax rate in the three and six months ended August 4, 2018 was significantly impacted by discrete tax benefits related to net excess tax windfalls from stock-based compensation resulting from increased option exercise activity and appreciation of the stock price, the reduction in the U.S. corporate income tax rate from 35% to 21% effective January 1, 2018 due to the passage of the Tax Cuts and Jobs Act (the “Tax Act”), and discrete tax impact related to a legal settlement. The effective tax rate in the three and six months ended July 29, 2017 was significantly impacted by non-deductible stock-based compensation, as well as the Company reporting a net loss before income taxes and, to a lesser extent, the net excess tax benefits from stock-based compensation. On December 22, 2017, the Tax Act was enacted in the United States. The Company recognized the income tax effects of the Tax Act in its fiscal 2017 financial statements in accordance with Staff Accounting Bulletin 118, which provides SEC staff guidance for the application of ASC Topic 740, Income Taxes, in the reporting period in which the Tax Act was signed into law. As noted in its fiscal 2017 consolidated financial statements, the Company was able to reasonably estimate certain effects and, therefore, recorded provisional amounts associated with the one-time transition tax on indefinitely reinvested foreign earnings and the adjustment to our deferred tax assets and liabilities for the reduction in the corporate income tax rate. The Company has not made any additional measurement period adjustments related to these items during the three and six months ended August 4, 2018. As the Company continues its analysis of the Tax Act and interprets any additional guidance, it may make adjustments to the provisional amounts that have been recorded that may materially impact the Company's provision for income taxes. As of August 4, 2018, the Company had $8.4 million of unrecognized tax benefits, of which $6.8 million would reduce income tax expense and the effective tax rate, if recognized. As of February 3, 2018, the Company had $8.2 million of unrecognized tax benefits, of which $6.5 million would reduce income tax expense and the effective tax rate, if recognized. The remaining unrecognized tax benefits would offset other deferred tax assets, if recognized. As of August 4, 2018, the Company had $0.4 million of exposures related to unrecognized tax benefits that are expected to decrease in the next 12 months.
