(4) Earned Premiums
Earned premiums for the Hurricane exposure locations was adjusted to add back premium ceded to third party reinsurers of $178 million for hurricane reinsurance purchased in Florida, the Northeast and other states during the period 1992 to 2005. These programs support management actions that address hurricane exposures. Mechanisms such as the FHCF and external reinsurance are available and are reflected in our capital structure because they help mitigate exposure to these types of events, but no impact is reflected in earned premiums above.
