The Company did not transfer any investment securities that were classified as AFS to HTM during the three and six months ended June 30, 2025 and 2024. During the three and six months ended June 30, 2025, the Company recorded a total of $1.8 million and $3.3 million, respectively, in amortization of unrecognized losses on investment securities previously transferred from AFS to HTM. During the three and six months ended June 30, 2024, the Company recorded a total of $1.9 million and $3.5 million, respectively, in amortization of unrecognized losses on investment securities previously transferred from AFS to HTM.

The Company elected to not measure an estimate of credit losses on accrued interest receivable as the Company writes off any uncollectible accrued interest receivable in a timely manner. Accrued interest receivable on investment securities is reported together with accrued interest receivable on loans and other assets in the consolidated balance sheets. Accrued interest receivable on investment securities totaled $4.7 million and $4.8 million as of June 30, 2025 and December 31, 2024, respectively.

The amortized cost, estimated fair value and weighted average yield of our AFS and HTM investment securities as of June 30, 2025, by contractual maturity, are shown below. Expected maturities may differ from contractual maturities because issuers may have the right to call or prepay obligations with or without call or prepayment penalties. Securities not due at a single maturity date are shown separately.

Investment securities in an unrealized or unrecognized loss position are evaluated at least on a quarterly basis, and include evaluating the changes in the investment securities' ratings issued by rating agencies and changes in the financial condition of the issuer. For mortgage-related securities, delinquency and loss information with respect to the underlying collateral, changes in levels of subordination for the Company's particular position within the repayment structure, and remaining credit enhancement as compared to projected credit losses of the security are also evaluated.

The Company has evaluated its AFS and HTM investment securities that are in an unrealized or unrecognized loss position and has determined that the losses on the Company's investment securities are unrelated to credit quality and primarily attributable to changes in interest rates and volatility in the financial markets since purchase. All of the investment securities in a loss position continue to be rated investment grade by one or more major rating agencies. The Company does not intend to sell the AFS and HTM securities that were in a loss position as of June 30, 2025 and December 31, 2024, and it is unlikely that the Company will be required to sell these securities before recovery of its amortized cost basis that may be at maturity. Therefore, the Company has not recorded an ACL on these securities.
