Loss from these investments totaled $56 and $51 during the three and nine months ended September 30 30, 2022, respectively. Income from these investments totaled $35 and $138 during the three and nine months ended September 30, 2021, respectively. Such amounts are included as a portion of interest and investment income on the Company’s consolidated statements of operations.

 

Based on the Company’s review of its debt securities that are individually in an unrealized loss position at September 30, 2022, it determined that the losses were primarily the result current economic factors, impacting all global debt and equity markets, that are the result of global macro events. The impact to the Company’s investment portfolio is considered to be temporary, rather than a deterioration of overall credit quality. As of September 30, 2022, all investments are current on their schedule interest and dividend payments. The Company does not intend to sell and it is not more likely than not that the Company will be required to sell these securities prior to recovering their amortized cost. As such, the Company does not consider these securities to be other-than-temporarily impaired at September 30, 2022.
