Income Taxes	(3) Income Taxes The provisions for income taxes for the 2021 and 2020 thirty-nine-week periods were based on estimated annual effective income tax rates of 24.4% and 24.2%, respectively, adjusted for discrete events, such as benefits resulting from stock-based awards. The increase in the estimated annual effective income tax rate was primarily attributable to increased anticipated nondeductible executive compensation during the 2021 period. The effective income tax rate for the 2021 thirty-nine-week period was 24.2%, which was higher than the statutory federal income tax rate of 21% primarily attributable to state taxes and nondeductible executive compensation, partially offset by excess tax benefits realized on stock-based awards. The effective income tax rate for the 2020 thirty-nine-week period was 23.3%, which was higher than the statutory federal income tax rate of 21% primarily attributable to state taxes and the meals and entertainment exclusion, partially offset by excess tax benefits realized on stock-based awards and state tax refunds.
