in economic conditions and other factors. As a result, our three ACLs might not be sufficient to cover actual credit losses, and future provisions for credit losses could materially adversely affect our operating results. In addition, various regulatory agencies, as an integral part of their examination process, periodically review our three ACLs. Such agencies may require us to recognize adjustments to the three ACLs based on their judgments about information available to them at the time of their examination.
Non-Interest Income
Non-interest income for the three months ended June 30, 2023 was $1.0 million compared to non-interest income of $536,000 for the three months ended June 30, 2022. The increase of $484,000, or 90.3%, in total non-interest income was primarily due to an increase of $403,000 in BOLI income, a decrease of $307,000 in unrealized loss on equity securities, and an increase of $7,000 in other non-interest income, partially offset by a decrease of $180,000 in other loan fees and service charges, a decrease of $46,000 in gain on sale of fixed assets, and a decrease of $7,000 in investment advisory fees.
The increase in BOLI income was primarily due to two death claims totaling $1.8 million on BOLI policies that resulted in additional BOLI income of $404,000 in the three months ended June 30, 2023. The decrease in unrealized loss on equity was due to an unrealized loss of $123,000 on equity securities during the three months ended June 30, 2023 compared to an unrealized loss of $430,000 on equity securities during the three months ended June 30, 2022. The unrealized loss of $123,000 on equity securities during the three months ended June 30, 2023 was due to market interest rate volatility during the quarter ended June 30, 2023.
The decrease of $180,000 in other loan fees and service charges was due to a decrease of $185,000 in other loan fees and loan servicing fees and a decrease of $4,000 in deposit fees, partially offset by an increase of $9,000 in ATM and debit card usage fees.
