Argonaut Group’s Trident Insurance Expands Identity Recovery Coverage to College and University Customers

September 26, 2005

San Antonio – Trident Insurance Services, LLC, a wholly owned subsidiary of Argonaut Group, Inc. (NASDAQ: AGII) announced at the annual National Association of Professional Surplus Lines Offices, Ltd. (NAPSLO) convention that it has extended its Identity Recovery Coverage to college and university customers. Beginning in April 2005, Trident Insurance first offered its public entity customers the Identity Recovery Coverage. Due to the high level of interest, positive response, and successful writings with public entities, Trident has added the coverage to its offerings of products designed for its College and University customers. For colleges and universities, the Identity Recovery Coverage protects faculty, employees, and students.

Identity Theft is America’s fastest growing crime with half of the publicized incidents of data breach since January 2005 occurring at universities, according to the San Diego-based Identity Theft Resource Center. Trident’s coverage provides its college and university customers a cost effective method of minimizing damage by combining identity theft insurance with a concierge service to assist identity theft victims in restoring their credit history and identity records. By utilizing the customized service, Trident’s coverage both reimburses victims for costs incurred to resolve problems resulting from identity theft as well as assisting the claimant through the challenging and time consuming effort of recovering credit and identity.

Trident has partnered with The Hartford Steam Boiler Inspection and Insurance Company (HSB), a part of HSB Group, Inc., a wholly owned subsidiary of American International Group, Inc. (NYSE: AIG) in offering identity recovery insurance as a standard part of its coverage for public entities and colleges and universities.

Trident President, Michael Arledge, stated, “Trident recognizes the seriousness and consequences of Identity Theft and we are proud to extend our coverage to colleges and universities. Our coverage focuses on recovery assistance for the victim and provides a case manager to assist the victim in correcting credit history and identity records. Other insurers provide identity recovery coverage but we are unmatched in offering the customized service that truly aids victims.”

Added Mark MacGougan, Vice President and Product Manager for HSB’s Identity Recovery Program, “We are pleased to be partnered with Trident as it expands its coverage for colleges and universities. Most identity products make the victim responsible for the work to restore their credit and identity records. Yet, many people are unfamiliar with the process. That’s a distraction that a university can’t afford.”
