As of March 31, 2025 and December 31, 2024, the gross unrealized losses on fixed maturity, available-for-sale securities without an allowance of $1,849 million and $2,059 million, respectively, related to “1” highest quality or “2” high quality securities based on the National Association of Insurance Commissioners (“NAIC”) or equivalent rating and $81 million and $102 million, respectively, related to other than high or highest quality securities based on NAIC or equivalent rating. As of March 31, 2025, the $1,754 million of gross unrealized losses of twelve months or more were concentrated in the Company’s corporate securities within the finance, consumer non-cyclical and utility sectors. As of December 31, 2024, the $1,894 million of gross unrealized losses of twelve months or more were concentrated in the Company's corporate securities within the finance, consumer non-cyclical and utility sectors.

In accordance with its policy described in Note 2 to the Consolidated Financial Statements included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2024, the Company concluded that an adjustment to earnings for credit losses related to these fixed maturity securities was not warranted at March 31, 2025. This conclusion was based on a detailed analysis of the underlying credit and cash flows for each security. Gross unrealized losses are primarily attributable to increases in interest rates, general credit spread widening and foreign currency exchange rate movements. As of March 31, 2025, the Company did not intend to sell these securities, and it was not more likely than not that the Company would be required to sell these securities before the anticipated recovery of the remaining amortized cost basis.

The following table sets forth the amortized cost and fair value of fixed maturities by contractual maturities, as of the date indicated:

Actual maturities may differ from contractual maturities because issuers may have the right to call or prepay obligations. Asset-backed, commercial mortgage-backed and residential mortgage-backed securities are shown separately in the table above, as they do not have a single maturity date.

The following table sets forth the sources of fixed maturity proceeds and related investment gains (losses), as well as losses on write-downs and the allowance for credit losses of fixed maturities, for the periods indicated:

For additional information regarding the Company’s methodology for developing its allowance and expected losses, see Note 2 to the Consolidated Financial Statements included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2024.

For the three months ended March 31, 2025, the net increase in the allowance for credit losses on available-for-sale securities was primarily related to net additions within the consumer non-cyclical and technology sectors within corporate securities due to adverse projected cash flows, partially offset by net reductions within the capital goods and consumer non-cyclical sectors with corporate securities primarily due to security restructures. For the three months ended March 31, 2024, the net decrease in the allowance for credit losses on available-for-sale securities was primarily related to net reductions within the finance sector within corporate securities.

The Company did not have any fixed maturity securities purchased with credit deterioration as of both March 31, 2025 and December 31, 2024.
Fixed Maturities, Trading
The net change in unrealized gains (losses) from fixed maturities, trading still held at period end, recorded within “Other income (loss),” was $87.8 million and $(81.3) million during the three months ended March 31, 2025 and 2024, respectively.
Equity Securities

The net change in unrealized gains (losses) from equity securities still held at period end, recorded within “Other income (loss),” was $(93.6) million and $(12.2) million during the three months ended March 31, 2025 and 2024, respectively.

For the three months ended March 31, 2025, the net increase in the allowance for credit losses on commercial mortgage and other loans was primarily related to an increase in loan-specific allowances within the retail sector of commercial mortgage loans. For the three months ended March 31, 2024, the net increase in the allowance for credit losses on commercial mortgage and other loans was primarily related to an increase in loan-specific allowances within the office sector and in the general allowance due to net negative credit migration.
