RECONCILIATION OF NON-GAAP MEASURES

The following table reconciles the underwriting profit (loss) by individual
segment and of the whole Company to consolidated income before taxes. We believe
that these measures are useful to investors in evaluating the performance of our
Company and its insurance segments because our objective is to consistently earn
underwriting profits. We evaluate the performance of our insurance segments and
allocate resources based primarily on underwriting profit (loss) of insurance
segments. Our definition of underwriting profit (loss) of insurance segments and
underwriting profit (loss) may not be comparable to that of other companies.
