Note 8.  Income Taxes

Our effective income tax rate for each of the second quarter and six months ended June 30, 2024 was 23.3%, compared to 24.4% for the same 2023 periods. The differences between our effective income tax rates and the U.S. federal statutory rate of 21.0% were mainly due to state income taxes.
