At March 31, 2024, the Company’s allowance for credit losses for loans was $18.9 million, or 1.00% of total loans, compared to $22.0 million, or 1.14% of total loans, at December 31, 2023 and $20.4 million, or 1.00% of total loans, at March 31, 2023.

The increase in net charge-offs during the first quarter of 2024 compared to the prior quarter of 2023 and the first quarter of 2023 was primarily due to activity in the current quarter. This activity involved partial charge-offs of two non-accrual loans totaling $2.9 million, as well as complete write-offs of five non-accrual loans totaling $435,000. These actions were taken due to collateral shortfalls deemed uncollectable.
