Description
This study was developed by the Mortality Quintile Analysis subgroup (Subgroup) of the SOA Individual Life Experience Committee (ILEC). The purpose of this study is to quantify the range of intercompany variability in mortality. To accomplish this, mean actual-to-expected (A/E) ratios based on amount were calculated in each quintile for every combination of six key variables. The companies assigned to each quintile were determined individually for each quintile in each category. In addition to calculating the ratios for each of the key variables, ratios for all combinations of two of the variables were calculated. In this report, Q1 represents the quintile with the highest A/E rating and Q5 the lowest. The data is based on experience consistent and contained in the ILEC fully underwritten reports. A full tabular listing of results is included as an accompanying Excel file.
