There were no borrowings under this line during 2025, 2024 or 2023, and no balance was outstanding at December 31, 2025, 2024 or 2023. There were no letters of credit outstanding during 2025, 2024 or 2023, and thus, no fees were received during these periods.

Directors of the Company and their beneficial interests have deposit accounts with the Bank and may be provided with cash management and other banking services, including loans, in the ordinary course of business. Such loans were made on substantially the same terms, including interest rates and collateral, as those prevailing at the time for comparable transactions with other unrelated persons and did not involve more than the normal risk of collectability.
