(3.) INVESTMENT SECURITIES (Continued)

The total number of AFS securities’ positions in the investment portfolio in an unrealized loss position was 185 at September 30, 2024 and 201 at December 31, 2023, respectively. At September 30, 2024, the Company had a position in 183 investment securities with a fair value of $804.6 million and a total unrealized loss of $127.4 million that had been in a continuous unrealized loss position for more than 12 months. At September 30, 2024, there were a total of two securities’ positions in the Company’s investment portfolio with a fair value of $15 thousand and a total unrealized loss of less than $1 thousand that had been in a continuous unrealized loss position for less than 12 months. At December 31, 2023, the Company had a position in 198 investment securities with a fair value of $835.5 million and a total unrealized loss of $151.5 million that had been in a continuous unrealized loss position for more than 12 months. At December 31, 2023, there were a total of three securities’ positions in the Company’s investment portfolio with a fair value of $8 thousand and a total unrealized loss of less than $1 thousand that had been in a continuous unrealized loss position for less than 12 months. The unrealized loss on investment securities was predominantly caused by changes in market interest rates subsequent to purchase. The fair value of the Company’s portfolio fluctuates as market interest rates change.

Securities Available for Sale

As of September 30, 2024 and December 31, 2023, no allowance for credit losses had been recognized on AFS securities in an unrealized loss position as management does not believe any of the securities were impaired due to reasons of credit quality. This is based upon our analysis of the underlying risk characteristics, including credit ratings, and other qualitative factors related to our available for sale securities and in consideration of our historical credit loss experience and internal forecasts. The issuers of these securities continue to make timely principal and interest payments under the contractual terms of the securities. Furthermore, the Company expects to recover the amortized cost basis of its investments and more than likely will not need to sell before the recovery period for operating purposes, with no impairment identified. As the portfolio is managed from a liquidity, earnings, and risk standpoint, sales from the AFS portfolio may be warranted based upon prevailing market factors. The unrealized losses are due to increases in market interest rates over the yields available at the time the underlying securities were purchased. The fair value is expected to recover as the securities approach their maturity date or repricing date or if market yields for such investments decline.

Securities Held to Maturity

The Company’s HTM investment securities include debt securities that are issued by U.S. government agencies or U.S. government-sponsored enterprises. These securities carry the explicit and/or implicit guarantee of the U.S. government, are widely recognized as “risk free,” and have a long history of zero credit loss. In addition, the Company’s HTM investment securities include debt securities that are issued by state and local government agencies, or municipal bonds.

The Company monitors the credit quality of our municipal bonds through the use of a credit rating agency or by ratings that are derived by an internal scoring model. The scoring methodology for the internally derived ratings is based on a series of financial ratios for the municipality being reviewed as compared to typical industry figures. This information is used to determine the financial strengths and weaknesses of the municipality, which is indicated with a numeric rating. This number is then converted into a letter rating to better match the system used by the credit rating agencies. As of September 30, 2024, $45.3 million of our municipal bonds were rated as an equivalent to Standard & Poor’s A/AA/AAA, with $3.2 million internally rated to be the equivalent of Standard & Poor’s A/AA/AAA rating. Additionally, no municipal bonds were rated below investment grade. As of December 31, 2023, $64.6 million of our municipal bonds were rated as an equivalent to Standard & Poor’s A/AA/AAA, with $4.2 million internally rated to be the equivalent of Standard & Poor’s A/AA/AAA rating, and no municipal bonds were rated below investment grade.

As of September 30, 2024 and December 31, 2023, the Company had no past due or nonaccrual held to maturity investment securities.
