Extortion Coverage Form G — an Insurance Services Office, Inc. (ISO), form (CR 00 08) that insures against loss of money, securities, and other property surrendered away from the premises as a result of a threat to do bodily harm to the insured, an employee, a relative, or invitee who is or allegedly is being held captive. Broader coverage, often at a reduced premium, can often be obtained by purchasing a separate kidnap and ransom policy from an insurer specializing in this field.
