Effect of Mortality Improvement on Expected Life Insurance Benefits

Abstract

The study examines the effect of mortality improvement on expected life insurance benefits, focusing on how changes in mortality patterns and increasing survival rates influence the expected financial obligations associated with life insurance policies. Mortality improvement refers to sustained reductions in mortality rates over time, often resulting in longer life expectancy. Such changes are important to life insurers because they can alter the timing and probability of benefit payments and consequently affect actuarial valuation and liability management. The study will investigate how mortality improvement affects the expected benefits payable under life insurance policies. It will examine changes in mortality and survival probabilities across different age groups and policy durations and assess their implications for the expected timing and value of insurance benefit payments. The study will also consider how alternative mortality improvement assumptions influence projected life insurance obligations. The analysis will focus on mortality rates, mortality improvement rates, survival probabilities, life expectancy, policy duration, benefit amounts, and expected benefit payments. Actuarial life tables and mortality projection techniques will be used to model changes in mortality experience and estimate expected life insurance benefits under alternative mortality assumptions. Comparative analysis will be conducted to assess differences in projected benefits under varying mortality improvement scenarios. A quantitative research approach will be adopted for the study. Relevant mortality and life insurance data will be obtained from appropriate secondary sources. Actuarial life table methods, survival probability calculations, mortality projection techniques, present value calculations, and descriptive statistical methods will be employed to estimate expected benefits and analyse the effect of mortality improvement on projected insurance obligations. The study is expected to reveal that mortality improvement produces measurable changes in the timing and expected value of life insurance benefits. Higher survival rates may delay the occurrence of death-related benefit payments for certain types of life insurance, while changes in the timing of benefit payments may affect their present value. The findings may also show that the magnitude of these effects varies according to policy duration, age structure, benefit design, and the assumed rate of mortality improvement. The findings are expected to provide useful information for life insurers, actuaries, underwriters, and insurance analysts in evaluating changing mortality experience. Understanding mortality improvement may support more accurate benefit projections, liability valuation, premium assessment, and long-term financial planning. The study may also assist insurers in reviewing mortality assumptions and adjusting actuarial models to reflect changes in population survival patterns. The study concludes that mortality improvement is an important consideration in estimating expected life insurance benefits and assessing future insurance liabilities. It is therefore recommended that life insurance companies regularly review mortality experience, update mortality assumptions, and incorporate appropriate mortality improvement projections into actuarial valuation and long-term insurance planning.
