The unrealized losses on the Company’s investment securities were primarily attributable to increases in market interest rates subsequent to their purchase by the Company. The Company expects the fair value of these securities to recover as the securities approach their maturity dates or sooner if market yields for such securities decline. The Company does not believe that these securities are other than temporarily impaired because of their credit quality or related to any issuer or industry specific event. Based on management’s evaluation and intent, the unrealized losses related to the investment securities in the above tables are considered temporary.

The Company had no sales and realized no gains or losses on sales of investment securities for the years ended March 31, 2023, 2022 and 2021.
