Insurance [Abstract] |
Future Policy Benefit Reserves | Future Policy Benefits Reserves Future policy benefits reserves are associated with the Company's run-off long-term care business, which is included in the Life & Group segment, and relate to policyholders that are currently receiving benefits, including claims that have been incurred but are not yet reported, as well as policyholders that are not yet receiving benefits. Future policy benefits reserves are comprised of the LFPB which is reflected as Insurance reserves: Future policy benefits on the Consolidated Balance Sheets. The determination of Future policy benefits reserves requires management to make estimates and assumptions about expected policyholder experience over the remaining life of the policy. Since policies may be in force for several decades, these assumptions are subject to significant estimation risk. As a result of this variability, the Company’s future policy benefits reserves may be subject to material increases if actual experience develops adversely to the Company’s expectations. Annually in the third quarter, actuarial analysis is performed on policyholder morbidity, persistency, premium rate increase and expense experience. This analysis, combined with judgement, informs the setting of updated cash flow assumptions used to estimate the LFPB. Actuarial analysis includes predictive modeling, actual to expected experience comparisons and trend analysis. Applicable industry research is also considered. The cash flow assumption updates completed in the third quarter of 2024 resulted in a $15 million pretax increase in the LFPB. Included in the assumption updates was a favorable impact from outperformance on premium rate assumptions and unfavorable impact from higher cost of care inflation. The cash flow assumption updates completed in the third quarter of 2023 resulted in an $8 million pretax increase in the LFPB. Persistency updates were unfavorable due to revisions to lapse rates. Morbidity updates were favorable driven by claim severity assumption updates, and there was a favorable impact from outperformance on premium rate assumptions. The following table summarizes balances and changes in the LFPB.
