The impact to the Company’s investment portfolio is considered to be temporary, rather than a deterioration of overall credit quality. As of March 31, 2023, all investments are current on their schedule interest and dividend payments.

As such, the Company does not consider these securities to be other-than-temporarily impaired at March 31, 2023.
