Taxes

Third quarter 2025 tax expense was $30 million, compared to $28 million of tax expense in the prior quarter and $20 million of tax expense in the same period last year. The effective tax rate for the third quarter of 2025 was 19.16%, compared to 20.34% in the prior quarter and 18.61% in the same period last year.

The ACLL to total loans ratio was 1.34% in the third quarter, down from 1.35% in the prior quarter and up from 1.33% in the same period last year.

In 2025, we continue to expect to adjust provision to reflect changes to risk grades, economic conditions, loan volumes, and other indications of credit quality.
