An actuarial investigation into the mortality of impaired insured lives

Abstract

This study tackles the main issues relating to a follow-up investigation of the mortality experience
among insured lives with various medical impairments identified at acceptance. Statistical methods are
described for analysing mortality data and for measuring the mortality experienced. It is intended to
analyse the prognostic experience of impaired insured lives and to compare it with a suitable standard in
order to describe the mortality pattern and to assess the prognostic significance of risk factors for various
impairments. For each impairment, detailed results of the relative mortality by age at entry, duration
since entry and time of entry are given. The results can be used to derive a set of ratings for use in the life
insurance underwriting of impaired lives.
