The increase was due to a 221 basis point, or 155.2%, increase in the average cost of borrowings to 3.63% for the three months ended March 31, 2023 from 1.42% for the three months ended March 31, 2022, and an increase in the average balance of borrowings of $41.0 million, or 129.2%, to $72.8 million for the three months ended March 31, 2023, from $31.8 million for the three months ended March 31, 2022.
Provision for Credit Losses. We establish provisions for credit losses, which are charged to operations to order to maintain the allowance for credit losses at a level we consider necessary to absorb credit losses inherent in our loan portfolio. We recorded a provision for credit losses of $240,000 for the three months ended March 31, 2023, compared to a provision for loan losses of $242,000 for the three months ended March 31, 2022. During the three months ended March 31, 2023, a net recovery of $2,000 was recorded, while a net charge-off of $26,000 was recorded for the three months ended March 31, 2022.
Noninterest Income. Noninterest income decreased $512,000, or 35.2%, to $942,000 for the three months ended March 31, 2023 from $1.5 million for the three months ended March 31, 2022. The decrease was primarily due to a decrease in mortgage banking income, net, and a decrease in brokerage commissions. For the three months ended March 31, 2023, mortgage banking income, net, decreased $357,000 to $43,000 and brokerage commissions decreased $121,000 to $168,000. The decrease in mortgage banking income was the result of a decrease in loans originated and sold through the FHLBC Mortgage Partnership Finance program in the nine months ended March 31, 2023, and the decrease in brokerage commissions was the result of a decrease in the amount of renewal commissions and management fees.
Noninterest Expense. Noninterest expense decreased $202,000, or 4.0%, to $4.8 million for the three months ended March 31, 2023 from $5.0 million for the three months ended March 31, 2022. The largest components of this decrease were compensation and benefits, which decreased $190,000, or 5.6%, and other expenses, which decreased $134,000, or 26.2%. These decreases were partially offset by a $77,000, or 15.8%, increase in equipment expense and a $26,000, or 152.9%, increase in audit and accounting. Compensation and benefits decreased due to a decrease in annual incentive plan expenses, and other expenses decreased as a result of a decrease in appraisal and other loan expenses. Equipment expense increased as a result of an increase in the cost of core processing and cybersecurity, while audit and accounting increased due to additional services received in the three months ended March 31, 2023.
Income Tax Expense. We recorded a provision for income tax of $202,000 for the three months ended March 31, 2023, compared to a provision for income tax of $402,000 for the three months ended March 31, 2022, reflecting effective tax rates of 22.6% and 25.8%, respectively.
