Life office mortality investigation
The CMI investigates the mortality experience of policyholders with assurances and annuitants of life offices.
The life office mortality investigation is the longest running investigation of the CMI. The full history of the investigation is detailed in CMI report 1.
Data and methodology
The CMI’s life office mortality investigation has, until recently, collected what is termed “scheduled" data. That is, the data provided by contributing offices has been in a census format containing the total numbers of policies (in force and deaths) split by age and duration. No policy specific details were requested from contributors which means that the level of analysis that could be carried out on the data has been limited. The analysis methodology is summarised in section 2 of CMI Working paper 45.
Starting with the submission of 2006 data, we have also received data submitted in accordance with the 'per policy' format which requires benefit specific information and also encompasses the CMI’s critical illness investigation. The initial methodology that is being used for the analysis of ‘per policy’ mortality data is contained in Appendix 1 of Working paper 56.
Contributing offices receive results in respect of the business for which they have submitted data. Aggregate ‘All Office’ results are also produced.
Working paper 56 sets out the initial format for results using ‘per policy’ mortality data. A template spreadsheet of per policy results can be accessed here. A discussion and consultation on how these initial results may develop in future is contained within Working paper 57.
- The 00 series base mortality tables were published in Working papers 21 and 22 and CMI Report 23.

- Earlier mortality tables were published in various printed volumes which are not available electronically.
- All published CMI base mortality tables are available in Excel format here.
Between the years 1982 and 2006, the CMI ran an investigation into the mortality of impaired assured lives. A report on the latest data and results, covering the years 1995 to 2006, is contained within Working paper 36.
