The IRF services claims for many of the risks of loss to which the State is exposed, including the following: property insurance on government owned buildings, the contents of such buildings, equipment, and automobiles; automobile liability insurance on government owned vehicles and school buses; tort liability insurance for government premises and operations; and medical professional liability for hospitals. The IRF purchases insurance to cover risks where it has limited expertise (aircraft insurance and ocean marine insurance). The IRF purchases reinsurance to limit losses in the areas of property, boiler and machinery, automobile liability, and medical professional liability. Reinsurance permits partial recovery of losses from reinsurers; but the IRF, as direct insurer of the risks, remains primarily liable.
