The effective tax rate was 11.6 percent for the three months ended March 31, 2024 compared to 12.1 percent for the three months ended March 31, 2023, driven by a larger net discrete tax benefit reflected in the three months ended March 31, 2024 compared to the same period in 2023.
The U.S. examination of tax years 2016-2018 began in 2019 and remains ongoing. The Internal Revenue Service commenced its examination of tax years 2019-2021 during the third quarter of 2023. The resolution of both audit periods will likely extend beyond the next 12 months.
