Authorities in Georgia have issued an arrest warrant for a Tennessee insurance agent who allegedly sold altered property-casualty insurance policies, collecting millions in improper commissions.

Edward Prater, 61, of Chattanooga, Tenn., faces charges of insurance fraud, theft by taking and first-degree forgery, according to the Georgia Department of Insurance.

The department alleges that Prater added commissions to policies when he claimed to policyholders that the coverage was being sold on a net basis with a set fee, but without a commission.

Georgia Insurance Commissioner John W. Oxendine said Prater was not a licensed insurance agent in the state, but through his agency, U.S. Insurance Group, headquartered in Chattanooga, sold the policies with improper commissions.

“Our investigation reveals that this suspect received $2.6 million in commissions he obtained by altering documents to deceive clients about their premium payments,” Oxendine said in a statement.

U.S. Insurance Group, co-founded by Prater in 1996, specializes in transportation-related coverages, Oxendine’s office said, adding that the alleged fraud began in 2003. Prater allegedly earned the commissions primarily on group auto insurance and workers’ compensation policies.

Oxendine said his office is investigating whether additional cases of overpayment in connection with Prater may exist.

The felony charge of insurance fraud carries a penalty of between two and 10 years in prison in Georgia and/or a fine of up to $10,000.
