As of March 31, 2024 and December 31, 2023, the gross unrealized losses on fixed maturity available-for-sale securities without an allowance of $30,334 million and $26,879 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 $1,104 million and $991 million, respectively, related to other than high or highest quality securities based on NAIC or equivalent rating. As of March 31, 2024, the $29,855 million of gross unrealized losses of twelve months or more were concentrated in the finance, consumer non-cyclical and utility sectors within corporate securities. As of December 31, 2023, the $26,855 million of gross unrealized losses of twelve months or more were concentrated in the finance, consumer non-cyclical and utility sectors within corporate securities and foreign government securities.

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, 2023, the Company concluded that an adjustment to earnings for credit losses related to these fixed maturity securities was not warranted at March 31, 2024. This conclusion was based on 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, 2024, 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 amortized cost basis.

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, 2023.
For the three months ended March 31, 2024, the net increase in the allowance for credit losses on available-for-sale securities was primarily related to net additions in the consumer cyclical and communications sectors within corporate securities due to adverse projected cash flows. Partially offsetting these additions, was a net release within foreign government securities. For the three months ended March 31, 2023, the net increase in the allowance for credit losses on available-for-sale securities was primarily related to net additions in the communications and finance sectors within corporate securities, as well as foreign government securities due to adverse projected cash flows. Partially offsetting the additions was a net release within the utility and capital goods sectors within corporate securities.

The Company did not have any fixed maturity securities purchased with credit deterioration, as of March 31, 2024 or December 31, 2023.
