In the three months ended March 31, 2024 and 2023, no unrealized losses on marketable securities were recognized in income.

The Company does not intend to sell and it is unlikely that it will be required to sell securities prior to their anticipated recovery. The issuers are high quality (investment grade) and the decline in fair value is largely due to changes in interest rates. Additionally, the issuers continue to make timely interest payments on the marketable securities with the fair value expected to recover as they reach maturity.
