At March 31, 2026, 48 debt securities designated as AFS were in an unrealized loss position. Based on our analysis of these securities, the decline in value was unrelated to credit loss and is related to changes in market interest rates since purchase, and therefore, changes in value for securities were included in other comprehensive income. In analyzing whether unrealized losses on debt securities are not related to credit losses, management takes into consideration, as applicable, whether the securities are issued by a governmental body or agency, whether the rating agency has downgraded the securities, industry analysts’ reports, the financial condition and performance of the issuer, and the quality of any underlying assets or credit enhancements. Market valuations and credit loss analysis on assets in the AFS securities portfolio are reviewed and monitored on a quarterly basis. None of the investments in our AFS securities portfolio were past due as of March 31, 2026. Management has the ability and intent to hold the securities for the foreseeable future and no declines are deemed to be related to credit losses; therefore, no provision for expected credit losses or allowance is carried for the AFS portfolio.

The following is a summary of amortized cost and estimated fair value of debt securities by contractual maturity as of March 31, 2026. Contractual maturities will differ from expected maturities for mortgage-backed securities because borrowers may have the right to call or prepay obligations without penalties.

Investment securities classified as HTM are recorded at amortized cost subject to measurement of credit losses on financial instruments, also known as Current Expected Credit Losses (“CECL”). This methodology consists of measuring the value of investments on a collective basis when similar risk characteristics exist. Our investment policy requires securities designated as HTM to carry an explicit or implicit guarantee of the United States Government (i.e., issued by the U.S. Treasury and federal agencies of the United States). Market valuations and credit loss analysis on assets in the HTM securities portfolio are reviewed and monitored on a quarterly basis. None of the investments in our HTM securities portfolio were past due as of March 31, 2026. An allowance for credit losses (“ACL”) is not calculated or recorded based on the implied guarantee of these securities.

The following table summarizes the remaining contractual principal maturities of investment securities classified as HTM as of March 31, 2026. For United States agency debentures, the expected maturity is the actual contractual maturity of the notes. Expected remaining maturities for certain United States agency debentures may occur earlier than their contractual maturities because the note issuers have the right to call outstanding amounts ahead of their contractual maturity.
