(1)Collateralized mortgage obligations and mortgage-backed securities consist of residential and commercial mortgage pass-through securities and collateralized mortgage obligations guaranteed by FNMA, FHLMC, GNMA and SBA.

Securities with a fair value of approximately $402,979 and $418,670 as of June 30, 2026 and December 31, 2025, respectively, were pledged as collateral for borrowings and public fund deposits, and for other purposes as required or permitted by law or regulation.

The amortized cost and fair value of securities available for sale as of June 30, 2026, by contractual maturity, are shown below. Certain securities have call features that allow the issuer to call the securities prior to maturity. Expected maturities may differ from contractual maturities for collateralized mortgage obligations and mortgage-backed securities because borrowers may have the right to call or prepay obligations with or without call or prepayment penalties. Therefore, collateralized mortgage obligations and mortgage-backed securities are not included in the maturity categories within the following maturity summary.

If the Company intends to sell, or it is more likely than not that it will be required to sell the security before recovery of its amortized cost basis, then the security is written down to fair value through income. As of June 30, 2026 and December 31, 2025, the Company did not have the intent to sell, nor was it more likely than not that it would be required to sell any of the securities in an unrealized loss position prior to recovery. As of June 30, 2026 and December 31, 2025, the Company also determined that no individual securities in an unrealized loss position represented credit losses that would require an allowance for credit losses. The Company concluded that the unrealized losses were primarily attributable to increases in market interest rates since these securities were purchased and other market conditions. Accrued interest receivable is not included in available-for-sale security balances and is presented in the "Accrued interest receivable" line of the Consolidated Balance Sheets. Interest receivable on securities was $2,271 and $2,354 as of June 30, 2026 and December 31, 2025, respectively, and was excluded from the measurement of credit losses.
