Income Taxes	9 Months Ended
Oct. 28, 2017
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 508.6% for the nine months ended October 28, 2017, compared to 41.1% for the nine months ended October 29, 2016. The increase in the effective income tax rate during the nine months ended October 28, 2017 compared to the same prior-year period was due primarily to more losses incurred in certain foreign jurisdictions where the Company has valuation allowances, a shift in the distribution of earnings among the Company’s tax jurisdictions within the quarters of the current fiscal year and a lower tax rate on the gain from the sale of a minority interest investment during the same prior-year period. During the nine months ended October 28, 2017, the Company adopted authoritative guidance which requires all income tax effects of stock awards (resulting from an increase or decrease in the fair value of an award from grant date to the vesting date) to be recognized in the income statement when the awards vest or are settled. This is a change from previous guidance that required such activity to be recorded in paid-in capital within stockholders’ equity. As a result, the Company recorded tax shortfalls of approximately $0.7 million as an increase to the Company’s income tax expense in its condensed consolidated statement of income (loss) during the nine months ended October 28, 2017. From time-to-time, the Company is subject to routine income tax audits on various tax matters around the world in the ordinary course of business. As of October 28, 2017, several income tax audits were underway for various periods in multiple jurisdictions. The Company accrues an amount for its estimate of additional income tax liability which the Company, more likely than not, will incur as a result of the ultimate resolution of income tax audits (“uncertain tax positions”). The Company reviews and updates the estimates used in the accrual for uncertain tax positions as more definitive information becomes available from taxing authorities, upon completion of tax audits, 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 $15.3 million and $14.6 million as of October 28, 2017 and January 28, 2017, respectively. The change in the accrual balance from January 28, 2017 to October 28, 2017 resulted from additional accruals and interest and penalties during the nine months ended October 28, 2017.
