Abstract

The study examines the comparative application of actuarial reserve valuation methods in life insurance. Actuarial reserves represent the amounts required by insurance companies to meet future obligations arising from existing policies. Accurate reserve valuation is essential for assessing insurer liabilities, maintaining financial stability, and ensuring that sufficient funds are available to meet future claims and policy benefits. Different actuarial reserve methods may produce varying results because they apply different approaches to the valuation of future premiums and benefits. The study will compare selected actuarial reserve valuation methods and examine the differences in the reserve values generated under each approach. Particular attention will be given to the net premium reserve method, prospective reserve method, retrospective reserve method, and other applicable valuation approaches. The study will assess how these methods respond to differences in policy duration, mortality assumptions, premium payments, benefit amounts, and interest rate assumptions. The analysis will focus on the principles, assumptions, and computational procedures underlying the selected reserve valuation methods. Actuarial present values of future benefits and premiums will be calculated under the different approaches, while mortality and survival probabilities, policy duration, premium structures, benefit levels, and discount rates will be incorporated into the valuation. The study will compare the resulting reserve estimates to determine the similarities, differences, and conditions under which the methods produce different valuation outcomes. A quantitative research approach will be adopted for the study. Hypothetical or secondary life insurance data and appropriate actuarial life tables will be used to construct representative policy scenarios. Actuarial reserve formulas, present value techniques, mortality and survival probabilities, discounting procedures, and comparative analysis will be employed to calculate reserves using the selected methods. The resulting estimates will be analyzed across different policy durations and actuarial assumptions. The study is expected to reveal that different actuarial reserve valuation methods can produce varying reserve estimates, particularly when the assumptions, timing of valuation, or treatment of premiums and benefits differ. Prospective and retrospective approaches are expected to provide comparable results under consistent actuarial assumptions, while differences may arise from the valuation framework and data assumptions applied. The study is also expected to show that changes in mortality rates, interest rates, policy duration, and premium structures can influence the magnitude of the differences between valuation methods. The study will provide useful information for actuaries, insurance companies, regulators, and researchers by improving understanding of the practical application of alternative reserve valuation methods. The findings may assist insurance practitioners in selecting appropriate valuation approaches, evaluating policy liabilities, monitoring reserve adequacy, and improving actuarial financial reporting. The study may also provide useful academic material for students and researchers examining life insurance reserve valuation. The study concludes that actuarial reserve valuation methods provide important approaches for estimating the financial obligations associated with life insurance policies, although their results may vary according to the valuation framework and assumptions employed. It is therefore recommended that insurers apply appropriate and consistent actuarial methods when determining reserves and regularly review the assumptions underlying their valuations. Sound actuarial practices should be maintained to support accurate liability estimation and effective management of insurance obligations.
