Spotlight on Longevity February 2013: High-age mortality convergence

Published by Dave Grimshaw, Mark Paulson on

Significant variations in mortality are often observed at working ages for different subgroups of a population.  It is widely-thought that these differences diminish at high ages so that the mortality rates for each subgroup converge to those of the aggregate population.  

Despite this, many published bases for valuation of annuity and pension scheme liabilities use mortality rates which differ significantly from population mortality at high ages.

Our Longevity Services team produce regular commentaries known as 'Spotlight on Longevity'.  These focus on topical issues for those involved in the management and transfer of longevity risk.
