Note: (A) The loss and LAE ratio component of the accident year combined ratio
measures losses and LAE arising from insured events that occurred in the
respective accident year. The current accident year excludes losses and LAE
for insured events that occurred in prior accident years.  Accident year 2003
as of Dec 31, 2003 measures insured events for the twelve months of 2003.
Accident year 2002 as of Dec 31, 2002 measures insured events for the twelve
months of 2002 with related outstanding liabilities estimated as of Dec 31,
2002. Accident year 2002 as of Dec 31, 2003 measures insured events for the
twelve months of 2002 with remaining related liabilities estimated as of
Dec 31, 2003. Partial and complete accident periods may not be comparable due
to seasonality, claim reporting and development patterns, claim settlement
rates and other factors.
