Excluding the effects of changes in the characteristics of individual debt securities that potentially give rise to credit losses, as described below, the fair market value of a debt security as of a particular measurement date is highly dependent upon prevailing market and economic environmental factors at the measurement date relative to the prevailing market and economic environmental factors present at the time the debt security was acquired. The most significant market and environmental factors include, but are not limited to (1) the general level of interest rates, (2) the relationship between shorter-term interest rates and longer-term interest rates (referred to as the “slope” or "shape" of the interest rate yield curve), (3) general bond market liquidity, (4) the recent and expected near-term volume of new issuances of similar debt securities, and (5) changes in the market values of individual loan collateral underlying mortgage-backed an asset-backed debt securities. Changes in interest rates affect the fair market values of debt securities by influencing the discount rate applied to the securities’ future expected cash flows. The higher the discount rate, the lower the resultant security fair value at the measurement date. Conversely, the lower the discount rate, the higher the resultant security fair value at the measurement date. In addition, the cumulative amount and timing of undiscounted cash flows of debt securities may also be affected by changes in interest rates. For any given level of movement in the general market and economic environmental factors described above, the magnitude of any particular debt security’s price changes will also depend heavily upon security-specific factors such as (1) the duration of the security, (2) imbedded optionality contractually granted to the issuer of the security with respect to principal prepayments, and (3) changes in the level of market premiums demanded by investors for securities with imbedded credit risk (where applicable). When the fair value of any individual security categorized as available-for-sale ("AFS") or held-to-maturity ("HTM") is less than its amortized cost basis, an assessment is made as to whether or not an adjustment to current earnings for credit loss is required. In assessing potential credit losses, management also makes a quantitative determination of potential credit loss for all HTM securities even if the risk of credit loss is considered remote and uses a best estimate threshold for securities categorized as AFS. The Company considers numerous factors when determining whether a potential credit loss exists. The principal factors considered are (1) the financial condition of the issue and (guarantor, if any) any adverse conditions specifically related to the security, industry or geographic area, (2) failure of the issuer of the security to make scheduled interest or principal payments, (3) any changes to the rating of the security by a nationally recognized statistical rating organization (“NRSRO”), and (4) the presence of contractual credit enhancements, if any, including the guarantee of the federal government or any of its agencies. The Company carries all of its AFS investments at fair value with any unrealized gains or losses reported, net of income tax effects, as an adjustment to shareholders' equity and included in accumulated other comprehensive income (loss), except for the credit-related portion of debt securities’ credit losses, if any, which are charged to earnings. The Company's ability to fully realize the value of its investments in various securities, including corporate debt securities, is dependent on the underlying creditworthiness of the issuing organization. In evaluating the debt securities portfolio (both AFS and HTM) for credit losses, management considers (1) the intent to sell the security; (2) if it is “more likely than not” the security is required to be sold before recovery of its amortized cost basis; or (3) if the present value of expected cash flows is insufficient to recover the entire amortized cost basis. The portion of the investment securities portfolio, categorized as AFS, with an aggregate amortized historical cost of $293.3 million, had an aggregate fair value that was less than its aggregate amortized historical cost by $9.2 million, or -3.1%, at March 31, 2025. The AFS securities portfolio, with an aggregate amortized historical cost of $279.6 million, had an aggregate fair value that was less than its aggregate amortized historical cost by $10.2 million, or -3.7%, at December 31, 2024. The resultant $1.0 million total improvement in the fair value of the AFS investment portfolio's aggregate fair value relative to its aggregate amortized historical cost, in the three months ended March 31, 2025, was primarily due to changes in the interest rate environment (the general interest rate level and the relationships between shorter-term and longer-term interest rates, known as the 'yield curve') that occurred in that period. These changes in aggregate fair value relative to aggregate amortized historical cost that occurred in the three months ended March 31, 2025 did not represent any changes in credit loss estimations within the portfolio. The portion of the investment securities portfolio, categorized as HTM, with an aggregate amortized historical cost of $156.0 million, had an aggregate fair value that was less than its aggregate amortized historical cost by $6.9 million, or -4.4%, at March 31, 2025. The portion of the investment securities portfolio, categorized as HTM, with an aggregate amortized historical cost of $158.9 million, had an aggregate fair value that was less than its aggregate amortized historical cost by $7.9 million, or -5.0%, at December 31, 2024. The resultant $1.0 million improvement in the aggregate fair value of the HTM investment portfolio, relative to its aggregate amortized historical cost, during the three months ended March 31, 2025, was primarily due to changes in the interest rate environment (the general interest rate level and the relationships between shorter-term and longer-term interest rates, known as the 'yield curve') that occurred in that period. These changes in aggregate fair value relative to aggregate amortized historical cost that occurred in the three months ended March 31, 2025 did not represent any changes in credit loss estimations within the portfolio. The Company does not intend to sell these securities, nor is it more likely than not that the Company will be required to sell these securities prior to the recovery of the amortized cost.

As of March 31, 2025 and December 31, 2024, securities with a fair value of $153.3 million and $119.8 million, respectively, were pledged to collateralize certain municipal deposit relationships. As of the same dates, securities with a fair value of $105.8 million and $123.2 million, respectively, were pledged against certain borrowing arrangements. Management has reviewed its loan and mortgage-backed securities portfolios and determined that, to the best of its knowledge, only minimal exposure exists to sub-prime or other high-risk residential mortgages. With limited exceptions in the Company’s investment portfolio involving the most senior tranches of securitized bonds, the Company is not in the practice of investing in, or originating, these types of investment securities.
