A “few” companies account
for much of the adverse development
Calendar Year 2002: 30 companies accounted for 80%
of the one-year development
Calendar Year 2003: 30 companies accounted for 90%
of the one-year development
Not all the same companies as prior year
The 30 companies (each year) held 20 – 25% of the
industry’s surplus

There are many process related drivers of
reserve development
External environment
Asbestos, pollution, construction defects
Runaway juries
Shock losses
WTC, Enron, Mutual Funds, Vioxx(??)
Methodologies
Chain-ladder, expected loss estimates
Data quality
TPA handled claims, poor systems
Knowledge of underlying exposure
©Towers Perrin
10
There are also decision-based questions that
can influence reserve adequacy
When to move off of an expected loss estimate (peg)?
Before IBNR is negative
How bad can a given year really be?
400% loss ratio is bad, 550% is worse
When is noise really an underlying trend ?
The “but for” rule
What can we afford to take/release?
Low end of talked down range
Can you say bias
Book the medium since reserves only go up

Like reserve adequacy, the underwriting cycle
is driven by many process-related factors
Prior year(s) loss estimates
Anticipated investment returns
External environment
Loss cost trend, inflation
Shock losses
Catastrophes
Market conditions
Terms and conditions
Rate changes
Underwriting criteria
Reinsurance costs
