Income Tax Disclosure [Abstract]
Income Tax Disclosure [Text Block]	Note 13. Income Taxes We recorded an income tax expense of $16,946 on a pre-tax income of $76,643 during the 13 weeks ended October 27, 2018, which represented an effective income tax rate of 22.1% and an income tax expense of $33,025 on pre-tax income of $81,420 during the 13 weeks ended October 28, 2017, which represented an effective income tax rate of 40.6%. We recorded an income tax expense of $2,974 on pre-tax income of $24,049 during the 26 weeks ended October 27, 2018, which represented an effective income tax rate of 12.4% and an income tax expense of $9,231 on pre-tax income of $22,843 during the 26 weeks ended October 28, 2017, which represented an effective income tax rate of 40.4%. The effective tax rate for the 13 and 26 weeks ended October 27, 2018 is significantly lower as compared to the comparable prior year period due to the tax benefit of U.S. Tax Reform, partially offset by permanent differences. Impact of U.S. Tax Reform The Tax Cuts and Jobs Act (the "Act") was enacted on December 22, 2017. The Act reduces the U.S. federal corporate tax rate from 35% to 21% and requires companies to pay a one-time transition tax on earnings of certain foreign subsidiaries that were previously tax deferred, among other provisions. As of October 27, 2018, we had not completed the accounting for the tax effects of enactment of the Act; however, as described below, we have made a reasonable estimate of the effects on existing deferred tax balances and the one-time transition tax in accordance with SAB 118, “Income Tax Accounting Implications of the Tax Cuts and Jobs Act” (SAB 118). These amounts are provisional and subject to change within the measurement period proscribed by SAB 118 which is not to extend beyond one year from the enactment date. The most significant impact of the legislation for the Company was a $20,425 reduction of the value of our net deferred (which represents future tax liabilities) and long-term tax liabilities as a result of lowering the U.S. corporate income tax rate from 35% to 21%, which was recorded in Fiscal 2018. During the second quarter of Fiscal 2019, we recorded an additional measurement period adjustment to further reduce our net deferred tax liability by $3,815 as a result of accelerating certain deductions as permitted by the U.S. tax code. This measurement period adjustment reduced the Company's effective tax rate by 5.0% and 16.0% during the 13 and 26 weeks ended October 27, 2018, respectively. We have provisionally recorded a liability associated with the one-time transition tax. This amount is not material. All amounts associated with the Act recognized as of October 27, 2018 are provisional. We expect to complete the accounting for the impacts of the Act in the third quarter of Fiscal 2019.

Impact of U.S. Tax Reform

The Tax Cuts and Jobs Act (the "Act") was enacted on December 22, 2017. The Act reduces the U.S. federal corporate tax rate from 35% to 21% and requires companies to pay a one-time transition tax on earnings of certain foreign subsidiaries that were previously tax deferred, among other provisions. As of October 27, 2018, we had not completed the accounting for the tax effects of enactment of the Act; however, as described below, we have made a reasonable estimate of the effects on existing deferred tax balances and the one-time transition tax in accordance with SAB 118, “Income Tax Accounting Implications of the Tax Cuts and Jobs Act” (SAB 118).

We have provisionally recorded a liability associated with the one-time transition tax. This amount is not material.

All amounts associated with the Act recognized as of October 27, 2018 are provisional. We expect to complete the accounting for the impacts of the Act in the third quarter of Fiscal 2019.
