Income Taxes	10. Income Taxes The provision for income taxes is based on the current estimate of the annual effective income tax rate and is adjusted as necessary for discrete quarterly events. The effective income tax rate for the 13 weeks ended August 4, 2018 was 21.9% compared to 34.0% for the 13 weeks ended July 29, 2017.

The decrease in the effective income tax rate for the 13 weeks and 26 weeks ended August 4, 2018 was primarily due to the reduction in the U.S. federal corporate tax rate from 35% to 21% as a result of the enactment of the Tax Cut and Jobs Act (the “Tax Act”) in December 2017, and excess tax benefits from share-based payments in accordance with ASU 2016-09 Compensation—Stock Compensation (Topic 718) (“ASU 2016-09”).

The provision for income taxes is based on the current estimate of the annual effective income tax rate and is adjusted as necessary for discrete quarterly events. The effective income tax rate for the 13 weeks ended August 4, 2018 was 21.9% compared to 34.0% for the 13 weeks ended July 29, 2017. The effective income tax rate for the 26 weeks ended August 4, 2018 was 21.9% compared to 33.2% for the 26 weeks ended July 29, 2017. The decrease in the effective income tax rate for the 13 weeks and 26 weeks ended August 4, 2018 was primarily due to the reduction in the U.S. federal corporate tax rate from 35% to 21% as a result of the enactment of the Tax Cut and Jobs Act (the “Tax Act”) in December 2017, and excess tax benefits from share-based payments in accordance with ASU 2016-09 Compensation—Stock Compensation (Topic 718) (“ASU 2016-09”).

The Company records accrued interest and penalties related to unrecognized tax benefits in income tax expense. The Company recognizes income tax liabilities related to unrecognized tax benefits in accordance with ASC 740 and adjusts these liabilities when its judgment changes as a result of the evaluation of new information not previously available. Unrecognized tax benefits decreased by approximately $1.7 million during the 13 weeks ended August 4, 2018 due to income tax settlements.
