​ Incurred liability adjustments relating to prior years, which affected current operations during 2025 and 2024, resulted in part from developed claims for prior years being different than were anticipated when the liabilities for unpaid claims were originally estimated. These trends have been considered in establishing the current year liability for unpaid claims.

​ Liability for Future Policy Benefits The liability for future policy benefits (“LFPB”) for individual and group annuities is generally equal to the present value of expected future policy benefit payments. The reserves are computed using assumptions for mortality and interest. The LFPB for non-participating term life insurance, individual disability income contracts and individual and group long-term care contracts is generally equal to the present value of expected future policy benefit payments less the present value of expected net premiums. The reserves are computed using assumptions for mortality, interest, morbidity and lapse. Cohorts are used as the unit of account for liability measurement. Actual cash flows are grouped into issue-year cohorts for the liability calculation and updated quarterly. We review and update, if necessary, assumptions used to measure cash flows for the LFPB during the third quarter of each year, or more frequently if evidence suggests assumptions should be revised. The change in our liability estimate as a result of updating cash flow assumptions is recognized in net income. ​ An interest accretion rate is determined for an identified cohort and remains unchanged after the issue year. For policies issued on or prior to December 31, 2020, the interest accretion rate is based on the assumed investment yield when the business was issued. For policies issued after December 31, 2020, the interest accretion rate is based on the upper-medium grade fixed-income instrument yields, which is generally equivalent to a single-A rated bond yield matched to the duration of our insurance liabilities, when the business was issued. The LFPB is remeasured to reflect current upper-medium grade fixed-income instrument yields as of each reporting date. The liability is calculated by discounting cash flows using rate curves reflecting the currency and duration of the insurance liabilities. For discount rate tenors, or points on the curves, where the upper-medium grade fixed-income instrument yields are not liquid or limited observable market data is available, we use various estimation techniques consistent with fair value measurement guidance. For our individual fixed income annuities in Latin America, the discount rate methodology is designed to prioritize observable inputs based on market data available in the local debt markets where the respective policies are issued in the currency in which the policies are denominated. For discount rate tenors where upper-medium grade fixed-income instrument yields based on international rating standards are not liquid or limited observable market data is available, estimation techniques are used to determine a curve in the appropriate currency. Further details regarding reference rates used are included under “Interest Accretion and Current Discount Rates.” Retirement and Income Solutions The balances and the changes in the present value for expected future policy benefits were as follows:

​ We updated our actuarial assumptions during the third quarter of 2024, resulting in a $32.3 million increase in the LFPB and an $18.2 million decrease to income before taxes, net of reinsurance, for Individual disability. This was primarily due to unfavorable updates to termination and lapse assumptions. The updates also resulted in a $68.2 million increase in the LFPB and a $52.9 million decrease to income before taxes, net of reinsurance, for Term life. This was primarily due to unfavorable updates to mortality and lapse assumptions. Additional Liability for Certain Benefit Features The LFPB also includes an additional reserve on certain universal life contracts where benefit features result in gains in early years followed by losses in later years. The liability for these future losses is accrued in relation to estimated contract assessments. A premium deficiency exists if the net liabilities together with future premiums are determined to be insufficient to provide for expected future policy benefits. Premium deficiency testing considers, among other factors, anticipated investment income and does not include a provision for adverse deviation. We did not have a premium deficiency reserve as of March 31, 2025 or December 31, 2024. The balances and the changes in the additional liability for certain benefit features for Life Insurance - Universal life contracts, excluding the impact of unrealized gains (losses), were as follows: ​

We updated our actuarial assumptions during the third quarter of 2024, resulting in a $151.9 million increase in the additional liability for certain benefit features primarily due to mortality assumptions related to ULSG products, resulting in a $0.3 million decrease to income before taxes, net of reinsurance.

​ Interest Accretion and Current Discount Rates The interest accretion rate shown for each level of aggregation is an average of the cohort-level accretion rates weighted by the reserve balance for each cohort within that level of aggregation. The current discount rate is calculated at a cohort-level based on current upper-medium fixed-income instrument yields and weighted by the reserve balance for each cohort within each level of aggregation. The weighted-average rates were as follows: ​
