15.    Income Taxes

Our effective tax rate for the three and six months ended June 30, 2022 was 24.5% and 24.6%, respectively, compared to 23.0% and 21.9% for the three and six months ended June 30, 2021, respectively. The increase in the effective tax rate in the three and six month periods of 2022 compared to the same periods in 2021 was primarily attributable to a lower income tax benefit recognized for excess tax benefits from stock option exercises, which totaled $8,744 and $17,190 for the three and six months ended June 30, 2022, respectively, and $11,213 and $28,590 for the three and six months ended June 30, 2021, respectively.
