Expected maturities may differ from contractual maturities because borrowers may have the right to call or prepay obligations with or without call or prepayment penalties. As of March 31, 2025 and December 31, 2024, 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.

The following table presents the fair value and the associated gross unrealized losses on AFS debt securities by length of time those individual securities in each category have been in a continuous loss as of March 31, 2025 and December 31, 2024:

Available-for-sale debt securities are measured at fair value and are subject to impairment testing. A security is impaired if the fair value of the security is less than its amortized cost basis. When an available-for-sale debt security is considered impaired, the Company must determine if the decline in fair value has resulted from a credit-related loss or other factors and then, (1) recognize an allowance for credit losses by a charge to earnings for the credit-related component of the decline in fair value, and (2) recognize in other comprehensive income (loss) any non-credit related components of the fair value decline. If the amount of the amortized cost basis expected to be recovered increases in a future period, the valuation reserve would be reduced, but not more than the amount of the current existing reserve for that security.

The unrealized losses from the decline in fair value is attributable to changes in interest rates, and not credit quality. The issuers of the AFS debt securities are of high credit quality. Approximately 97% of the AFS debt securities are residential mortgage-backed securities and residential collateralized mortgage obligations that were issued by U.S. government-sponsored agencies, such as Ginnie Mae, Fannie Mae and Freddie Mac. The remaining 3% of the AFS debt securities are tax-exempt municipal securities.

All securities are performing and the Company believes that the unrealized losses presented in the previous tables are temporary and no credit losses are expected. As a result, the Company expects full collection of the carrying amount of these securities, does not intend to sell the securities in an unrealized loss position, and it was more-likely-than-not the Company will not have to sell these securities prior to recovery of amortized cost. Accordingly, for available-for-sale debt securities, the Company did not have allowance for credit losses as of March 31, 2025 and December 31, 2024.

As of March 31, 2025 and December 31, 2024, there were no pledged securities to secure public deposits, borrowing and letters of credit from the Federal Home Loan Bank System ("FHLB") and the Board of Governors of the Federal Reserve System, and for other purposes required or permitted by law.
