Experience analysis – a brief overview
“Making sense of the past” – Luc and Spivak
Good quality data
– Complete and correct capture of all risk factors
– Be careful of different data cohorts causing heterogeneity
Correct age definitions (4-8% impact)
Using an appropriate table (by age, sex and smoker status)
Applying appropriate IBNR factors (4% impact)
Retain all factors in data, e.g. don’t lose product type split
Roll data forward to allow for trends, e.g. rebase to current year

CI related issuesImpact of external factors
Troponins
No data adjustment could understate average experience over analysis period
Care needs to be taken when measuring historical trend => could overstate future experience
Cancer Screening
Likely to cause “shock” in cancer incidence
Dealing with shock will depend on its maturity or likelihood of occurring

CI related issuesProduct changes
Adding new illnesses
Starting point is HES data/internet, but number of adjustments are necessary
Could often result in no cost, but need to be careful
TCF issues?
Experience unstable, trends unpredictable?
Definitions tight as intended?
Other unintended consequences?

Slide 15
How could it be priced?
Question Possible answer
Anti-selective behaviour Underwriting and claims management robust. Only identify lives aware they are HIV positive at issue.But no fishing allowed at claim stage!
Estimated impact between 0.1% and 0.3% of portfolio claim cost
Proportion of business from:– Single males with cover between
£250k and £1m– Unaware they are HIV positive
10%
0.05%
Assumed mortality rate for a life who is HIV positive
Age specific mortality for HIV life based on Danish experience 2000-2005 (equivalent to assuming life expectancy of 24 years for a male age 35)
Assumed lapse behaviour once a life is aware that they are HIV positive
Once life aware HIV positive then no lapses. Assume aware shortly after policy issue. Note that the later the diagnosis the higher the expected HIV mortality

Assume excess lapses are ‘healthy’ lives – i.e. wouldn’t be rated at time of lapse. These lives would therefore have better claim experience that the remainder of the cohort
Judgement required on how much healthier!!

Slide 19
Quantifying impact of changes
Business operations constantly changing, e.g. intro of tele u/w, more leniency on non-disclosure, changes to proposal form => impacts claims experience
How could claims experience be “corrected” for these changes?
Might be possible to rate changes and track over time
Ratings subjective at first, but over time possible to develop feel for how changes might impact claims experience enabling cost/benefit analyses

Slide 20
Key take-aways
Understand the data – not all fluctuations are random
What’s changed or changing?
– Talk to marketing, underwriting, claims, risk management, distributors, customers
Adjust historic data to make it relevant for projecting the future
– Correct for distortions in experience data
– Bring together different data sources
New realistic reporting and solvency environment
– Important to justify assumptions
