September 30, 2026 compared to December 31, 2025

Total investments increased primarily due to growth in the business, the receipt of the A&E ADC commutation settlement amount, and higher valuations within limited partnerships and other alternative investments, partially offset by lower valuations on fixed maturities, AFS, at fair value due to higher interest rates.

[1]Yields calculated using annualized net investment income divided by the monthly average invested assets at amortized cost, as applicable, excluding derivatives book value.

[2]Includes net investment income on short-term investments.

[3]Primarily includes changes in fair value of certain equity fund investments and income from derivatives that qualify for hedge accounting and are used to hedge fixed maturities.

Total net investment income increased primarily due to higher income from limited partnerships and other alternative investments and the impact of a higher level of invested assets.

Annualized net investment income yield, excluding limited partnerships and other alternative investments, increased for the nine month period primarily due to the impact of reinvesting at higher rates.

Average reinvestment rates of fixed maturities and mortgage loans, excluding U.S. Treasury securities, for both the three and nine months ended September 30, 2026 was 5.7% and 5.5% respectively, which was above the average yield of sales and maturities of 5.0% and 4.9%, respectively. Average reinvestment rates of fixed maturities and mortgage loans, excluding U.S. Treasury securities, for the three and nine months ended September 30, 2025, were 5.7% for both periods, which were above the average yield of sales and maturities of 5.2% and 4.9%, respectively.

For the 2026 calendar year, we estimate net investment income to increase due to a higher level of invested assets and a higher yield on limited partnerships and other alternative investments compared with 2025. Actual net investment income is subject to variability including the impact of evolving market conditions.
