The Company does not believe that the available-for-sale debt securities that were in an unrealized loss position as of June 30, 2026, which were comprised of 321 individual securities, represent a credit loss impairment. All of these securities were issued by U.S. government agencies, U.S. government-sponsored enterprises, local municipalities, or represent corporate debt. The securities issued by the U.S. government agencies or U.S. government-sponsored enterprises are either explicitly or implicitly guaranteed by the U.S. government, are highly rated by major rating agencies and have a long history of no credit losses. The securities issued by local municipalities and the corporate debt issues were all highly rated by major rating agencies and have no history of credit losses. The unrealized losses were primarily attributable to changes in the interest rate environment and not due to the credit quality of these investment securities. As of June 30, 2026, the Company does not have the intent to sell these investment securities and it is more likely than not that we will not be required to sell these securities before their anticipated recovery, which may be at maturity.

All of the Company’s held-to-maturity debt securities are issued by U.S. government agencies or U.S. government-sponsored enterprises. These securities are either explicitly or implicitly guaranteed by the U.S. government, are highly rated by major rating agencies and have a long history of no credit losses. The decline in fair value of the held-to-maturity debt securities were primarily attributable to changes in the interest rate environment and not due to the credit quality of these investment securities, therefore, the Company did not record an allowance for credit losses for these securities as of June 30, 2026.

The following table presents the credit quality of our held-to-maturity securities, based on the latest information available as of June 30, 2026 (in thousands). The credit ratings are sourced from nationally recognized rating agencies, which include Moody’s and S&P, and they are presented based on asset type. All of our held-to-maturity securities were current in their payment of principal and interest as of June 30, 2026.
