Available for sale debt securities balances exclude accrued interest receivable of $2.3 million and $3.1 million, respectively, as of March 31, 2026 and December 31, 2025.

At March 31, 2026 and December 31, 2025, securities with a fair value of $377.6 million and $392.4 million, respectively, were pledged as collateral for FHLB borrowings, potential borrowings with the FRBB, certain public deposits, and for other purposes. See Note 9 for additional discussion on FHLB borrowings.

The schedule of maturities of available for sale debt securities is presented below. Mortgage-backed securities are included based on weighted average maturities, adjusted for anticipated prepayments. All other debt securities are included based on contractual maturities. Actual maturities may differ from amounts presented because certain issuers have the right to call or prepay obligations with or without call or prepayment penalties.

Final maturities of the callable securities range from 1 year to 19 years, with call features ranging from 1 month to 7 years.

Assessment of Available for Sale Debt Securities for Impairment

Management assesses the decline in fair value of investment securities on a regular basis. Unrealized losses on debt securities may occur from current market conditions, increases in interest rates since the time of purchase, a structural change in an investment, volatility of earnings of a specific issuer, or deterioration in credit quality of the issuer. Management evaluates both qualitative and quantitative factors to assess whether an impairment exists.

The following tables summarize available for sale debt securities in an unrealized loss position, for which an ACL on securities has not been recorded, segregated by length of time that the securities have been in a continuous unrealized loss position:

Total	3	$2,130	($6)	99	$493,660	($100,065)	102	$495,790	($100,071)

There were no debt securities on nonaccrual status at March 31, 2026 and 2025 and, therefore there was no accrued interest related to debt securities reversed against interest income for the three months ended March 31, 2026 and 2025.

As of March 31, 2026, the Corporation does not intend to sell the debt securities in an unrealized loss position and has determined that it is more-likely-than-not that the Corporation will not be required to sell each security before the recovery of its amortized cost basis. In addition, management does not believe that any of the securities are impaired due to reasons of credit quality. As further described below, management believes the unrealized losses on these debt securities are primarily attributable to changes in the investment spreads and interest rates. Therefore, no ACL was recorded at both March 31, 2026 and December 31, 2025.

Obligations of U.S. Government Agency and U.S. Government-Sponsored Enterprise Securities, including Mortgage-Backed Securities

The contractual cash flows for these securities are either explicitly or implicitly guaranteed by the U.S. government, are highly rated by major credit rating agencies, and have a long history of no credit losses. The issuers of these securities continue to make timely principal and interest payments, and none of these securities were past due at March 31, 2026. Additionally, the Corporation utilizes a zero credit loss estimate for these securities.

Individual Name Issuer Trust Preferred Debt Securities

These securities in an unrealized loss position at March 31, 2026 included two trust preferred securities issued by two individual companies in the banking sector. Management reviewed the collectability of these securities taking into consideration such factors as the financial condition of the issuers, reported regulatory capital ratios of the issuers, credit ratings, including ratings in effect as of the reporting period date, as well as credit rating changes between the reporting period date and the filing date of this report, and other information. As of March 31, 2026, there was one individual name issuer trust preferred debt security with an amortized cost of $2.0 million and unrealized losses of $69 thousand that was rated below investment grade by S&P. We noted no downgrades to below investment grade between March 31, 2026 and the filing date of this report. Based on the information available through the filing date of this report, all individual name issuer trust preferred debt securities continue to accrue interest and make payments as expected with no payment deferrals or defaults on the part of the issuers.

Corporate Bonds

These securities in an unrealized loss position at March 31, 2026 included three corporate bond holdings issued by two individual companies in the financial services industry. Management reviewed the collectability of these securities taking into consideration such factors as the financial condition of the issuers, reported regulatory capital ratios of the issuers, credit ratings, including ratings in effect as of the reporting period date, as well as credit rating changes between the reporting period date and the filing date of this report, and other information. As of March 31, 2026, there were no corporate bond debt securities that were rated below investment grade by S&P. We noted no downgrades to below investment grade between March 31, 2026 and the filing date of this report. Based on the information available through the filing date of this report, all corporate bond debt securities continue to accrue interest and make payments as expected with no payment deferrals or defaults on the part of the issuers.
