There was no other than temporary impairment loss recognized on any securities at September 30, 2022 or 2021.

Unrealized losses on corporate bonds have not been recognized into income because the issuers’ bonds are of high credit quality (rated AA or higher), management does not intend to sell and it is likely that management will not be required to sell the securities prior to their anticipated recovery, and the decline in fair value is largely due to changes in interest rates and other market conditions. The issuers continue to make timely principal and interest payments on the bonds. The fair value is expected to recover as the bonds approach maturity.

The mortgage-backed securities held by the Company were issued by U.S government-sponsored entities and agencies. Because the decline in fair value is attributable to changes in interest rates and illiquidity, and not credit quality, and because the Company does not have the intent to sell these mortgage-backed securities and it is likely that it will not be required to sell the securities before their anticipated recovery, the Company does not consider these securities to be other-than-temporarily impaired at September 30, 2022 and 2021.
