The allowance for credit losses on held-to-maturity securities is a contra-asset valuation account that is deducted from the amortized cost basis of held-to-maturity securities to present the net amount expected to be collected. Management measures expected credit losses on held-to-maturity securities on a collective basis by major security type with each type sharing similar risk characteristics, and considers historical credit loss information that is adjusted for current conditions and reasonable and supportable forecasts. With regard to residential mortgage-backed securities issued by the U.S. government, or agencies thereof, it is expected that the securities will not be settled at prices less than the amortized cost basis of the securities as such securities are backed by the full faith and credit of and/or guaranteed by the U.S. government. Accordingly, no allowance for credit losses has been recorded for these securities. With regard to municipal securities issued by States and political subdivisions and other held-to-maturity securities, management considers (i) issuer bond ratings, (ii) historical loss rates for given bond ratings, (iii) whether issuers continue to make timely principal and interest payments under the contractual terms of the securities, (iv) internal forecasts and (v) whether or not such securities are guaranteed or pre-refunded by the issuers.

As of June 30, 2026, the Company held 327 available-for-sale securities of which 51 securities were in an unrealized loss position for less than twelve months and 102 securities were in an unrealized loss position for twelve months or more without an allowance for credit losses. Because the decline in fair value is attributable to changes in interest rates and not credit quality and because the Company does not have the intent to sell and it is likely that the Company will not be required to sell the securities prior to their anticipated recovery at maturity, it has been determined that there is no expected credit loss on these securities. Management evaluates the available-for-sale securities in an unrealized loss position, relying primarily on industry analyst reports and observations of market conditions and interest rate fluctuations.

Maturities are based on the final contractual payment dates, and do not reflect the impact of contractual monthly principal payments, prepayments or early redemptions that may occur. Expected maturities of mortgage-backed and CMO securities may differ from contractual maturities because borrowers have the right to call or prepay obligations with or without call or prepayment penalties.

The Company monitors the credit quality of those held-to-maturity securities not issued by the U.S. government or one of its agencies or government sponsored entities, through the use of credit ratings. Credit ratings are reviewed and updated quarterly. Nonrated municipal investments consist primarily of

bonds issued by political subdivisions such as housing authorities and reclamation districts. Nonrated municipal investments are monitored through financial covenants and review of repayment history. As of June 30, 2026, there were no past due principal or interest payments associated with held-to-maturity municipal securities. There were no holdings of securities of any one issuer, other than the U.S. Government and its agencies, in an amount greater than 10% of shareholders’ equity.
