RVI Guaranty Co. Ltd. (Bermuda) and its Connecticut-domiciled subsidiaries, RVI America Insurance Co. and RVI National Insurance Co. have had their financial strength rating (FSR) of A- (excellent) and issuer credit ratings (ICR) of "a-" placed under review with negative implications by AM Best Co.

RVI Guaranty is a specialty insurance group that primarily writes residual value insurance.

It is one of the largest insurance companies' specialising in underwriting and marketing of residual value insurance risk for clients engaged in the asset-based financing and securitisation industry. Most often, coverage is purchased by clients in order to comply with certain regulatory and financial accounting requirements.

The under review status reflects Best's concerns regarding RVI Guaranty's 2008 total year operating performance, which is expected to be substantially below 2007. The reduction in the 2008 operating performance reflects anticipated claims expected to be paid in future years from RVI Guaranty's passenger vehicle line of business, the largest segment of its insured portfolio. The losses are directly attributable to the decline of pre-owned (used) automobile values.
