_______________
(1)Amounts represent the sum of MRB assets and MRB liabilities presented on the consolidated balance sheets at September 30, 2025 and 2024, with the exception of $29 million and $47 million, respectively, of index-linked annuities not included in this table.
Market conditions, including, but not limited to, changes in interest rates, equity indices, market volatility and variations in actuarial assumptions, including policyholder behavior, mortality and risk margins related to non-capital markets inputs, as well as changes in nonperformance risk, may result in significant fluctuations in the estimated fair value of the guarantees. As part of the 2025 and 2024 AAR, the Company updated assumptions regarding policyholder behavior, mortality and separate account fund allocations. The impact from changes in assumptions is presented in effect of changes in future expected assumptions in the table above.
