The provision for credit losses is based upon management’s estimate of future expected credit losses in the loan portfolio and its evaluation of the adequacy of the ACL. Our provision for credit losses in 2024 totaled $11.4 million, compared to $11.6 million in 2023. Net charge-offs of recorded in 2024 totaled $11.8 million, compared to net charge-offs of $11.8 million in 2023. While the total charge-offs stayed constant, our charge off percentage on commercial real estate loans declined in 2024 due to one significant charge-off in 2023 on a property taken into OREO and sold within three months. In 2024, the charge-off percentage on powersport loans and installment and other loans increased due to weakening economic conditions. Our ACL to average loans was 1.7% as of December 31, 2024 and 2023.
