​ ​ Securities, other than mortgage-backed securities, are classified according to their contractual maturities without consideration of principal amortization, potential prepayments, or call options. The expected maturities may differ from contractual maturities because of the exercise of call options and potential paydowns. Accordingly, actual maturities may differ from contractual maturities. ​ Information pertaining to securities with gross unrealized losses at September 30, 2025 and December 31, 2024 aggregated by investment category and length of time that individual securities have been in a continuous loss position, follows: ​

​ At September 30, 2025 and December 31, 2024, the Company held 48 and 41 securities, respectively, with an unrealized loss. The securities with unrealized losses consisted of mortgage-backed securities guaranteed by the government-sponsored enterprises that have a credit rating consistent with the U.S. Government, and debt obligations guaranteed by federal, state and local government entities. These unrealized losses relate principally to noncredit related factors, including changes in current interest rates for similar types of securities. The Company does not intend to sell these securities, and it is more likely than not that the Company will not be required to sell the securities before recovery of their amortized cost basis. Based on management’s evaluation of the securities portfolio, the Company did not establish an allowance for credit losses for its available-for-sale or held-to-maturity securities at September 30, 2025 or December 31, 2024.
