Credit Quality Information

We monitor the credit quality of available-for-sale debt securities through credit ratings from various rating agencies and substantial price changes. In an effort to make informed decisions, we utilize credit ratings that express opinions about the credit quality of a security. Securities are triggered for further review in the quarter if the security has significant fluctuations in ratings, significant pricing changes, or drops below investment-grade. For securities without credit ratings, we utilize other financial information indicating the financial health of the underlying municipality, agency, or organization associated with the underlying security.

The Company has one previously identified nonaccrual corporate bond with a carrying value of $1.3 million as of March 31, 2026 and $2.2 million as of December 31, 2025. During the period, due to continued credit deterioration the Company did an additional write-down of $896 thousand, which is included in the loss on available-for-sale debt securities in the consolidated statements of income.

The table below presents a rollforward by major security type for the quarters ended March 31, 2026 and 2025 of the allowance for credit losses on available-for-sale debt securities held at period end:

The amortized cost and estimated fair value of available-for-sale debt securities segregated by contractual maturity at March 31, 2026 are presented below. Expected maturities may differ from contractual maturities because issuers may have the right to call or prepay obligations. Mortgage-backed securities and collateralized mortgage obligations are shown in total, as their maturities are highly variable.

The following summarizes, by investment security type, the impact of performing securities in an unrealized loss position at March 31, 2026:

Obligations of US Government-sponsored enterprises

6 out of the total 6 securities in our portfolio of AFS obligations of US Government-sponsored enterprises were in unrealized loss positions. Aggregate unrealized losses represented 2.24% of the amortized cost of securities in unrealized loss positions. The US Small Business Administration guarantees the contractual cash flows of all of our obligations of US Government-sponsored enterprises. The securities are investment grade rated and there were no material underlying credit downgrades during the quarter. Because the decline in fair value is attributable to changes in interest rates, and not credit quality, and the Company does not have the intent to sell these securities and it is likely that it will not be required to sell the securities before their anticipated recovery, the securities are investment grade rated and there were no material underlying credit downgrades during the quarter. All securities are performing.

US Government-sponsored enterprises

398 out of the total 509 securities in our portfolio of AFS US Government-sponsored enterprises were in unrealized loss positions. Aggregate unrealized losses represented 12.35% of the amortized cost of securities in unrealized loss positions. The Federal National Mortgage Association and Federal Home Loan Mortgage Corporation guarantee the contractual cash flows of all of our US Government-sponsored enterprises. The securities are investment grade rated and there were no material underlying credit downgrades during the quarter. Because the decline in fair value is attributable to changes in interest rates, and not credit quality, and the Company does not have the intent to sell these securities and it is likely that it will not be required to sell the securities before their anticipated recovery, the securities are investment grade rated and there were no material underlying credit downgrades during the quarter. All securities are performing.

US Government agency

136 out of the total 170 securities in our portfolio of AFS US Government agency securities were in unrealized loss positions. Aggregate unrealized losses represented 7.35% of the amortized cost of securities in unrealized loss positions. The Government National Mortgage Association guarantees the contractual cash flows of all of our US Government agency securities. The securities are investment grade rated and there were no material underlying credit downgrades during the quarter. Because the decline in fair value is attributable to changes in interest rates, and not credit quality, and the Company does not have the intent to sell these securities and it is likely that it will not be required to sell the securities before their anticipated recovery, the securities are investment grade rated and there were no material underlying credit downgrades during the quarter. All securities are performing.

Private label

14 of the total 15 securities in our portfolio of AFS private label mortgage-backed securities were in unrealized loss positions. Aggregate unrealized losses represented 6.80% of the amortized cost of securities in unrealized loss positions. We expect to receive all of the future contractual cash flows related to the amortized cost on these securities. Because the decline in fair value is attributable to changes in interest rates, and not credit quality, and the Company does not have the intent to sell these securities and it is likely that it will not be required to sell the securities before their anticipated recovery, the securities are investment grade rated and there were no material underlying credit downgrades during the quarter. All securities are performing.

Obligations of states and political subdivisions thereof

54 of the total 64 securities in our portfolio of AFS municipal bonds and obligations were in unrealized loss positions. Aggregate unrealized losses represented 15.59% of the amortized cost of securities in unrealized loss positions. We continually monitor the municipal bond sector of the market carefully and periodically evaluate the appropriate level of exposure to the market. At this time, we believe (i) the bonds in this portfolio carry minimal risk of default and (ii) we are appropriately compensated for the risk. There were no material underlying credit downgrades during the quarter. Because the decline in fair value is attributable to changes in interest rates, and not credit quality, and the Company does not have the intent to sell these securities and it is likely that it will not be required to sell the securities before their anticipated recovery, the securities are investment grade rated and there were no material underlying credit downgrades during the quarter. All securities are performing.

Corporate bonds

20 out of the total 33 securities in our portfolio of AFS corporate bonds were in an unrealized loss position. The aggregate unrealized loss represents 4.07% of the amortized cost of bonds in unrealized loss positions. We review the financial strength of all of these bonds, and we have concluded that the amortized cost remains supported by the expected future cash flows of these securities. The most recent review includes all bond issuers and their current credit ratings, financial performance and capitalization. Because the decline in fair value is attributable to changes in interest rates, and not credit quality, and the Company does not have the intent to sell these securities and it is likely that it will not be required to sell the securities before their anticipated recovery, the securities are investment grade rated and there were no material underlying credit downgrades during the quarter. All but the one corporate bond discussed above are performing.

We expect to recover the amortized cost basis on all securities in our AFS portfolio. Furthermore, we do not intend to sell nor do we anticipate that we will be required to sell any securities in an unrealized loss position as of March 31, 2026, prior to this recovery.
