Income Tax Disclosure [Abstract]
Income Taxes	Income Taxes Income tax expense for the interim periods was computed using the tax rate estimated to be applicable for the full fiscal year, adjusted for discrete items. The Company’s effective income tax rate was 52.2% for the six months ended August 3, 2019, compared to 24.0% for the six months ended August 4, 2018. The deterioration in the effective income tax rate during the six months ended August 3, 2019 was due primarily to the impact of discrete non-deductible expenses as compared to the same prior-year period and a shift in the distribution of earnings among the Company’s tax jurisdictions within the quarters of the current fiscal year. In December 2017, the U.S. government enacted the 2017 Tax Cuts and Jobs Act (“Tax Reform”), which significantly changed the U.S. corporate income tax laws, including lowering the U.S. federal corporate income tax rate from 35% to 21% and requiring a one-time mandatory transition tax on accumulated foreign earnings. The Tax Reform also established new tax laws that were effective for calendar 2018, including but not limited to (i) a new provision designed to tax global intangible low-taxed income (“GILTI”), (ii) a general elimination of U.S. federal income taxes on dividends from foreign subsidiaries, (iii) a limitation on deductible interest expense and (iv) limitations on the deductibility of certain executive compensation. Any income tax payable related to the transition tax is due over an eight-year period beginning in calendar 2018. Based on the Company’s interpretation of the Tax Reform, reasonable estimates were made to record provisional adjustments during the fourth quarter of fiscal 2018. During the third quarter of fiscal 2019, the Company completed the preparation of its U.S. federal tax return for fiscal 2018 and concluded, based on the additional information that had become available, that no transition tax was due with respect to the Tax Reform. As a result, during the third quarter of fiscal 2019, the Company reversed a portion of provisional amounts initially recorded during the three months ended February 3, 2018 and recorded a benefit of $19.6 million. On November 28, 2018, the U.S. Internal Revenue Service (“IRS”) announced a proposed regulation to revise the section of the underlying IRS code which gave rise to the Company’s change in the provisional calculation. As a result, during the fourth quarter of fiscal 2019, the Company determined that in the event such proposed legislation is passed in the future, the Company could have tax liabilities of approximately $25.8 million. Therefore, the Company accrued such amount in the fourth quarter of fiscal 2019. During the second quarter of fiscal 2020, the Company revised its tax liability estimation and related accrual to $23.2 million. The balance related to this transition tax included in other long-term liabilities was $23.2 million and $25.8 million as of August 3, 2019 and February 2, 2019, respectively. From time-to-time, the Company is subject to routine income and other tax audits on various tax matters around the world in the ordinary course of business. As of August 3, 2019, several tax audits were ongoing for various periods in multiple jurisdictions. These audits could conclude with an assessment of additional tax liability for the Company. These assessments could arise as the result of timing or permanent differences and could be material to the Company’s net income or future cash flows. In the event the Company disagrees with an assessment from a taxing authority, the Company may elect to appeal, litigate, pursue settlement or take other actions. The Company accrues an amount for its estimate of additional tax liability which the Company, more likely than not, will incur as a result of the ultimate resolution of tax audits (“uncertain tax positions”). The Company reviews and updates the estimates used in the accrual for uncertain tax positions, as appropriate, as more definitive information or interpretations become available from taxing authorities, upon completion of tax audits, upon receipt of assessments, upon expiration of statutes of limitation, or upon occurrence of other events. The Company had aggregate accruals for uncertain tax positions, including penalties and interest, of $40.1 million and $41.4 million as of August 3, 2019 and February 2, 2019, respectively.
