The provisions for income taxes for the 2020 and 2019 thirteen-week periods were each based on an estimated annual effective income tax rate of 24.2%, adjusted for discrete events, such as benefits resulting from stock-based awards. The effective income tax rate for the 2020 thirteen-week period was 22.9%, 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. The effective income tax rate for the 2019 thirteen-week period was 21.0%, which approximated the statutory federal income tax rate of 21%. The provision for income taxes for the 2019 thirteen-week period was favorably impacted by $2,571,000 of excess tax benefits from stock-based awards, which essentially offset the impact of state taxes and the meals and entertainment exclusion.
