ALLOWANCE FOR CREDIT LOSSES* – LOANS*

The allowance for credit losses on loans, a contra-asset, is established through periodic provisions for credit losses on loans. It is maintained at a level that is considered adequate to measure expected losses on individually identified loans, as well as expected losses inherent in the remaining loan portfolio. Specifically identifiable and quantifiable losses are

immediately charged off against the allowance; recoveries are generally recorded only when sufficient cash payments are received subsequent to the charge-off.

The Company's allowance for credit losses on loans was $27.1 million at March 31, 2025, as compared to $24.8 million at December 31, 2024, and $23.1 million at March 31, 2024. The increase is primarily attributable to an increase in the allowance for loans individually evaluated and was specifically related to a $11.9 million single loan relationship of a wine grape grower. The allowance was 1.17% of total loans at March 31, 2025, 1.07% of total loans at December 31, 2024, and 1.07% of total loans at March 31, 2024. Management's detailed analysis indicates that the Company's allowance for credit losses on loans should be sufficient to cover credit losses for the life of the loans outstanding as of March 31, 2025, but no assurance can be given that the Company will not experience substantial future losses relative to the size of the credit loss allowance for loans. The total allowance for credit losses on loans of $27.1 million at March 31, 2025, included $0.3 million of allowance related to $283.2 million of mortgage warehouse lines. A separate allowance of $0.8 million for potential credit losses inherent in unused commitments is included in other liabilities at March 31, 2025, an increase of $0.1 million, from December 31, 2024.
