The amortized cost and estimated fair value as of June 30, 2026, excluding accrued interest receivable, of available-for-sale and held-to-maturity debt securities are presented below by contractual maturity.

At June 30, 2026, the Company had 45 available-for-sale debt securities in an unrealized loss position, comprised of 38 residential mortgage-backed securities, five commercial mortgage-backed securities and two credit risk transfer securities. The unrealized losses on the available-for-sale debt securities were the result of changes in market interest rates compared to the date the securities were acquired rather than the credit quality of the issuers or underlying loans. The Company does not currently intend to sell and based on current conditions it does not believe it is likely that the Company will be required to sell these available-for-sale debt securities before recovery of the amortized cost of such securities in an unrealized loss position and has therefore recorded the unrealized losses related to this portfolio in accumulated other comprehensive income (“AOCI”). Held-to-maturity debt securities consist of government guaranteed securities for which no loss is expected. At June 30, 2026 and December 31, 2025, no allowance for credit losses was established for available-for-sale or held-to-maturity debt securities.
At June 30, 2026 and December 31, 2025, debt securities with carrying values of approximately $876,000 and $937,000, respectively, were pledged to secure certain customer deposits.
