key outcome to measure success
risk measure e.g. VaR
links outcome to capital needed
given degree of confidence
given time horizon

hold more to
reduce risk of available capital < minimum
greater security for policyholders

Risks
Insurance risk
risk of loss from inherent uncertainty of
occurrence
amount
timing

premiums
expenses
Gross underwriting risk
Gross reserving risk
relates to risks yet to be written/earned
Sources
attritional loss frequency

mis-pricing risk
claims inflation
legislation / court awards
volumes/mix of business
anti-selection risk
underwriting cycle
latent claims
propensity to claim
macroeconomic conditions
capital charge
UW result at chosen risk tolerance
for business written/earned
UW result on a realistic basis
any expected profit should be excluded
divide firm's business
classes
territories/currencies
data required
estimates of future business volumes and mix
firm's BE business plan
claims and expense ratios for each class
historic performance
market experience
adjust for differences
assess variability of claims and expenses
fit statistical distributions
use stress tests
split claims
attritional
large
catastrophes
future latent
claims made during extreme conditions
below reinsurance retention
model in aggregate based on past experience
use mildly-skewed distribution
e.g. lognormal
test against experience
if SD small % of mean use N distribution
if insufficient data use loss ratios
model separately to attritional
allow for reinsurance recoveries
use F-S approach based on past experience
e.g. Poisson for frequency
heavily-skewed distribution for severity
e.g. Pareto
derive or test against revalued historic data
cannot model using past experience (too rare)

if large
writing significant volumes of business
writing capital-intensive business e.g. CAT risks
