Income Tax Disclosure [Abstract]
Income Taxes	NOTE 10—INCOME TAXES The Company recorded income tax expense of $5.2 million and $6.2 million in the three months ended November 3, 2018 and October 28, 2017, respectively. The Company recorded income tax expense of $16.7 million and $9.9 million in the nine months ended November 3, 2018 and October 28, 2017. The effective tax rate was 18.9% and 32.1% for the three months ended November 3, 2018 and October 28, 2017, respectively. The effective tax rate was 12.7% and 83.7% for the nine months ended November 3, 2018 and October 28, 2017, respectively. The effective tax rates for the three and nine months ended November 3, 2018 were 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 favorable legal settlement. The effective tax rates for the three and nine months ended October 28, 2017 were impacted by net excess tax benefits from stock-based compensation, and the effective tax rate for the nine months ended October 28, 2017 was also significantly impacted by non-deductible 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 nine months ended November 3, 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 November 3, 2018, the Company had $8.3 million of unrecognized tax benefits, of which $7.2 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 November 3, 2018, the Company had $0.4 million of exposures related to unrecognized tax benefits that are expected to decrease in the next 12 months.
