During the three and nine months ended September 30, 2026, the Company recorded a total of $1.8 million and $5.0 million, respectively, in amortization of unrecognized losses on investment securities previously transferred from AFS to HTM. During the three and nine months ended September 30, 2025, the Company recorded a total of $1.8 million and $5.1 million, respectively, in amortization of unrecognized losses on investment securities previously transferred from AFS to HTM.

The Company elected to not estimate credit losses on accrued interest receivable, as any uncollectible accrued interest receivable is written off 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. As of September 30, 2026 and December 31, 2025, accrued interest receivable on investment securities totaled $5.2 million and $4.5 million, respectively.

The amortized cost, estimated fair value and weighted average yield of the Company's AFS and HTM investment securities as of September 30, 2026, are presented below, grouped by contractual maturity. Expected maturities may differ from contractual maturities due to the issuer's option to call or prepay obligations, with or without penalties. Securities that are not due at a single maturity date, such as mortgage-backed securities and other asset-backed investments, are presented separately.

Investment securities in an unrealized or unrecognized loss position are evaluated at least quarterly to determine whether a credit loss exists. This evaluation includes a review of changes in the investment securities' credit ratings issued by major rating agencies and assessments of the issuers' financial condition. For mortgage-related securities, the Company also considers delinquency and loss data related to the underlying collateral, changes in subordination levels for the Company's position within the repayment structure, and remaining credit enhancement relative to projected credit losses.

The Company has reviewed its AFS and HTM investment securities that are in an unrealized or unrecognized loss position and determined that the losses are not related to credit quality, but are primarily attributable to changes in interest rates and volatility in the financial markets since the time of purchase. All of the investment securities in a loss position continue to be rated investment grade by one or more major rating agencies.

As of September 30, 2026 and December 31, 2025, the Company did not intend to sell the AFS and HTM securities that were in a loss position, and it was not more likely than not that the company would be required to sell such securities before recovery of their amortized cost basis. The Company evaluated these securities for credit losses and concluded that the decline in fair value was not attributable to credit factors. Accordingly, no ACL was recorded on these securities.
