Historical Catastrophe Experience Since the beginning of 1992, the average annual impact of catastrophes on our Property-Liability loss ratio was 7.6 pts. However, this average does not reflect the impact of some of the more significant actions we have taken to limit our catastrophe exposure. Consequently, we think it is useful to consider the impact of catastrophes after excluding losses that are now partially or substantially covered by the CEA, FHCF or placed with a third party, such as hurricane coverage in Hawaii. The average annual impact of all catastrophes, excluding losses from Hurricanes Andrew and Iniki and losses from California earthquakes, on our Property-Liability loss ratio was 6.0 points since the beginning of 1992.
Comparatively, the average annual impact of catastrophes on the homeowners loss ratio for the years 1992 through 2004 is shown in the following table.
