Note 8.  Income Taxes

Our effective income tax rate for each of the third quarter and nine months ended September 30, 2022 was 24.7%, compared to 25.5% in the same 2021 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, partially offset by the effects of company-owned life insurance policies.
