Income Tax Disclosure [Abstract]
Income Taxes	6. Income Taxes The Company’s effective income tax rates for the three and nine months ended October 31, 2020 were 78.6% and 36.1%, respectively. The effective income tax rates for the three and nine months ended November 2, 2019 were 23.6% and 22.5%, respectively. The change in the effective income tax rate from the prior year and prior quarter and in comparison to the statutory rate was driven by the carryback of net losses and associated tax planning strategies that offset income from taxable years where the rate was 35%, as contemplated by the CARES Act. The Company is continuing to evaluate tax planning strategies, which may drive additional material tax benefits in the balance of the year.
