Comparison of Results of Operations for the Nine Months Ended September 30, 2022 and 2021.
General. For the nine months ended September 30, 2022, the Company reported net income of $26,000, compared to net income of $1.8 million for the nine months ended September 30, 2021. During the nine months ended September 30, 2021, the Company received a $1.8 million Rapid Response Program grant from the CDFI Fund and recognized the amount in non-interest income. During the nine months ended September 30, 2022, the Company received and recognized into non-interest income a $171,000 BEA Program grant from the CDFI Fund. The Bank also rebranded and officially changed its name to Catalyst Bank during the 2022 period. Pre-tax costs associated with the rebranding of the Bank totaled $270,000 for the nine months ended September 30, 2022. Professional fees associated with the grant totaled $26,000 and were recorded in non-interest expense in the same period.
Interest Income. Total interest income increased $93,000, or 1.6%, to $5.9 million for the nine months ended September 30, 2022, from $5.8 million for the nine months ended September 30, 2021. This increase was primarily attributable to a $628,000 increase in interest income on investment securities and a $225,000 increase in other interest income, partially offset by a decrease in interest income on loans of $760,000.
The average loan yield was 4.64% for the nine months ended September 30, 2022, down from 4.99% for the nine months ended September 30, 2021. In addition, average loans were $132.1 million for the nine months ended September 30, 2022, down $11.0 million, or 7.7%, compared to the same period in 2021. Loan income from the recognition of deferred PPP loan fees totaled $186,000 for the nine months ended September 30, 2022, down $94,000, or 33.6%, from $280,000 recognized in the same period in 2021.
The increase in interest income on investment securities was primarily due to an increase in the average volume of our securities portfolio. The average amortized cost balance of our investment securities was up $53.2 million, or 104.5%, for the nine months ended September 30, 2022, compared to the same period in 2021. During the fourth quarter of 2021, the Company deployed $41.9 million of the proceeds from our IPO into the investment securities portfolio.
Interest Expense. Total interest expense decreased $141,000, or 22.8%, to $477,000 for the nine months ended September 30, 2022 from $618,000 for the nine months ended September 30, 2021. Interest expense on deposits was $272,000 during the nine months ended September 30, 2022, down $142,000, or 34.3%, from $414,000 for the nine months ended September 30, 2021. While the average balance of our total interest-bearing deposits increased by $2.9 million, or 2.0%, to $150.0 million for the nine months ended September 30, 2022 compared to the nine months ended September 30, 2021, the average rate paid on interest-bearing deposits decreased by 14 basis points to 0.24% for the nine months ended September 30, 2022 compared to the nine months ended September 30, 2021.
Net Interest Income. Net interest income was $5.4 million for the nine months ended September 30, 2022, an increase of $234,000, or 4.5%, compared to the nine months ended September 30, 2021. Our average interest rate spread was 2.52% and 2.93% for the nine months ended September 30, 2022 and 2021, respectively. Our net interest margin was 2.69% and 3.09% for the nine months ended September 30, 2022 and 2021, respectively. The decline in interest rate spread and net interest margin over the prior comparable periods was primarily the result of lower average yield on loans and a shift in the mix of our interest-earning assets as we grew our investment securities portfolio and experienced a decline in total loans. The impact on yield due to these factors more than offset the increase in yield on other interest-earning assets and the reduction in the average cost of our interest-bearing liabilities.
Provision for Loan Losses. During the nine months ended September 30, 2022 and 2021, the Company recorded reversals to the allowance for loan losses of $375,000 and $286,000, respectively. The amounts recorded during both periods primarily reflect the release of reserve builds recorded during 2020 for the estimated effects of the COVID-19 pandemic on credit quality.
Non-interest Income. Non-interest income decreased by $1.5 million, or 63.7%, to $872,000 for the nine months ended September 30, 2022 from $2.4 million for the nine months ended September 30, 2021. In August 2021, the Bank was awarded a $1.8 million grant from the U.S. Treasury Department’s CDFI Rapid Response Program, which was recognized as non-interest income.
