Theme Chinas life insurance market is huge at the moment, anticipating fast growth for the next decade or two. Reliable mortality tables are essential.

8 Problems to face

Problem # 1 Current tables are out of date

Problem # 2 Need different tables for different purposes a) Population tables b) Group insurance tables c) Individual insurance tables d) Annuitant tables

Problem #3 Current tables data from group insurance

Problem #4 Using wrong tables could have disastrous consequences. Equitable Life in UK

Problem #5 Vast mortality differences between regions

Problem #6 Underwriting practice can make a difference.

Problem #7 One table for all wont work.

Problem #8 Many of these problems will stay with us forever no matter what we do. This is a big big problem.

Solution #1 Do not guarantee annuity rates. To do so could lead a company to bankruptcy if scientists find a cure for cancer.

Solution #2 - use of credibility theory to adjust a currently-in-use mortality table Fast and effective Simple – anybody can use Applicable to any situation, any time Not perfect, but a vast improvement over the unadjusted table

Example Company uses CL1 table (q). Expected total deaths = 600 (E) Actual total deaths = 360 (A) m = A/E = 0.6 Z = 0.03 sqrt(E) or 1,whichever is smaller = 0.735 q = [1 – 0.735 (1 – 0.6)] q = 0.706 q

Notes For internal use, not for regulatory filing For conservatism – add 5% for insurance, minus 5% for annuity Disregard accuracy for individual ages – this would be an impossible task Introduction from - Foundations of Casualty Actuarial Science, 4 th edition, 2001 by Casualty Actuarial Society
