The Company reviews all securities with unrealized losses on a quarterly basis to assess whether the decline in the securities fair value necessitates the recognition of an allowance for credit losses. The Company considers numerous factors in its review as described in Note 1 of the Notes to the Consolidated Financial Statements in the 2024 Annual Report on Form 10-K.

Based on the Company’s review as of June 30, 2025, the Company determined that the fixed maturity securities’ unrealized losses were primarily the result of the interest rate environment and not the credit quality of the issuers. The Company does not intend to sell the investments and it is not more likely than not that the Company will be required to sell the investments before the recovery of their amortized cost basis.
