Note 7.  Income Taxes

Our effective income tax rate for each of the second quarter and six months ended June 30, 2023 was 24.4%, compared to 24.7% for the same 2022 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.
