Strong Risk Management Focus -
Portfolio Expected Risk Curve (January 1, 2008)
Stated tolerance is to limit
our loss in a 1-in-100 year
to 25% of our capital or
less, our current level is
18.9% of capital
The above chart represents a cumulative analysis of our in-force underwriting portfolio on a full year basis based on thousands of
potential scenarios. Loss years are driven largely by the occurrence of natural catastrophes and incorrect pricing of other property and
casualty exposures. The operating income depicted includes net premiums earned plus net investment income, acquisition expenses
and G&A expenses. The operating income depicted excludes the effects of income tax (expenses) benefits, amortization of intangibles
and interest expense. Forecasted investment income, acquisition and G&A expenses are held constant across all scenarios. Losses
included above are net of reinsurance including collateralized reinsurance and ILW purchases. Our stated objective is to maintain a risk
management tolerance that limits our loss in a 1-in-100 year year to be no more than 25% of our equity capital. We base our budget
and forecasts on the average result, although the nature of the curve places the median result further to the right.
