"Citizens Property Insurance Corporation was created by the Florida Legislature in August 2002 as a not-for-profit, tax-exempt, government entity. Its mission is to provide insurance protection to Florida policyholders who are entitled to but are unable to find property insurance coverage in the private market.
Citizens customers include Florida home, business and condominium owners, as well as Florida property owners who come to Citizens seeking coverage. Citizens is funded by policyholder premiums and, additionally, if its surplus is depleted in the wake of a particularly devastating storm or series of storms, Florida law requires Citizens to levy assessments on most Florida property-casualty insurance policyholders until any deficit is eliminated. These financial responsibilities drive Citizens' commitment to quality customer service and rigorously sound financial management."
