Experience Rating Considerations
  • Lack of credible data
  • Weighting of individual years
  • Changes in Limit profiles
  • Changes in mix of business, classes of business
  • Legislative changes
  • New lines of business
  • Excess Leverage effect

8
Exposure Rating
  • What to do when there is very little individual
    company data ?
  • Exposure rating ?Industry Burning cost
  • Exposure curves give distribution of loss
    relative to the insured limit
  • With exposure data (limit profile) can then
    develop expected losses
  • Loss ratio of portfolio is an important factor
  • Source of curves ISO, internal data

9
Loss Modeling
  • Mathematical relationships which describe losses
  • Typical Reinsurance models
  • Pareto distribution for Severity
  • Poisson distribution for Frequency
  • Log Normal distribution for Loss Ratio
  • Mean and Variance are important
  • Parameter Uncertainty
  • Simulation tools

10
Modeling
  • Loss Sensitive Features
  • Sliding scale commissions
  • Profit commissions
  • No Claims Bonus
  • Swing Rates
  • Deficit Carryforwards
  • Payout Patterns/Discounting

11
Capital Allocation
  • Why we hold Capital
  • Regulators
  • Rating Agencies
  • Risk
  • Risk ? Volatility

Historical Results
May include primary business written in same
legal entity. Includes treaty and facultative.
Combined is sum of all legal entities owned by
the same group. Swiss Re premium is gross of
internal quota shares. Allocation of premium,
losses, commisions to casualty (automobile,Liabili
ty) may not be accurate for multiline
treaties. Combined ratio is estimated by adding
average commission/brokerage for each company.

Conclusions
  • Reinsurance pricing applies similar actuarial
    techniques as primary pricing
  • More reliance on statistical methods and
    distributions due to smaller quantity of data
  • One step further removed from insured, data
    quality, company knowledge critical
