Gross unrealized losses for investments in fixed maturities for twelve months or more was less than $0.1 million for both June 30, 2022 and December 31, 2021.

As of June 30, 2022, 287 of the securities held were in an unrealized loss position. The Company determined that unrealized losses on fixed maturities were primarily due to the interest rate environment, and not credit risk related to the issuers of these securities. The Company does not intend to sell these investment in fixed maturities, and it is not more likely than not that that the Company will be required to sell these investment in fixed maturities before recovery of the amortized cost basis. No allowance for credit losses related to any of these securities was recorded for the three and six months ended June 30, 2022. The Company does not measure an allowance for credit losses on accrued interest receivable and would instead write off accrued interest receivable at the time an issuer defaults or is expected to default on payments.
