The Company evaluates investments that are in an unrealized loss position for impairment as a result of credit loss. It was determined that no credit losses exist as of June 30, 2024 and December 31, 2023 because the change in market value for those securities in an unrealized loss position resulted from fluctuating interest rates rather than a deterioration of the credit worthiness of the issuers.

The gains and losses recorded on available-for-sale debt securities and equity securities are included in investment income, net in the Company’s condensed consolidated statements of operations. The gains and losses recorded were not material for the three and six months ended June 30, 2024 and 2023.
