Abstract

Mortality risk is a major component of life insurance business because insurers are exposed to financial obligations arising from the death of policyholders. Mortality risk transfers provide mechanisms through which insurers can transfer part or all of their exposure to mortality-related losses to other parties, particularly through reinsurance arrangements. Effective management of mortality risk transfers is therefore important for controlling life insurance liability exposure and maintaining financial stability. This study examines the effect of mortality risk transfers on life insurance liability exposure. The study will assess how the transfer of mortality-related risks influences the level and structure of liabilities retained by life insurance companies. It will focus on the extent to which mortality risk transfer arrangements can alter insurers’ exposure to future death claims and related financial obligations. The study will consider factors such as mortality rates, policyholder age distribution, claim frequency, sum assured, policy duration, risk retention levels, reinsurance recoveries, and the proportion of mortality risk transferred. It will also examine how changes in mortality experience and risk transfer levels may affect gross and net insurance liabilities. These factors will provide a basis for evaluating changes in the mortality-related liability exposure of life insurers. A quantitative research approach will be adopted for the study. Relevant life insurance and mortality data will be analysed using descriptive statistics, actuarial liability valuation techniques, ratio analysis, scenario analysis, and sensitivity analysis. Different mortality risk transfer and retention scenarios will be examined to determine their effects on life insurance liability exposure and to assess the extent to which transferred mortality risks reduce the liabilities retained by insurers. The study is expected to reveal that higher levels of mortality risk transfer may reduce the net mortality-related liability exposure retained by life insurance companies. However, the extent of the reduction may depend on mortality experience, risk retention levels, reinsurance arrangements, and the reliability of expected recoveries. The findings may also indicate that changes in mortality rates can significantly influence both gross and net liability positions. The study will be useful to actuaries, life insurance companies, reinsurers, regulators, and financial managers involved in mortality risk management and liability valuation. It may provide useful information for evaluating mortality risk transfer arrangements, estimating retained liabilities, improving reinsurance decisions, strengthening capital planning, and managing exposure to unexpected mortality losses. The study concludes that mortality risk transfers can play an important role in managing life insurance liability exposure by redistributing mortality-related financial obligations. It is therefore recommended that life insurance companies regularly evaluate mortality experience, establish appropriate risk retention levels, assess reinsurance recoverability, and apply sound actuarial techniques when measuring liabilities after mortality risk transfers.
