OLDWICK, N.J.--(BUSINESS WIRE)--Oct. 17, 2003--A.M. Best Co. has affirmed the financial strength rating of A (Excellent) for the property/casualty pooling members of Harleysville Insurance, (Harleysville, PA). Also, A.M. Best has affirmed the "bbb+" debt rating for Harleysville Group Inc.'s (HGIC) (NASDAQ: HGIC) existing senior notes and the indicative ratings of "bbb+" senior debt, "bbb" subordinated debt, "bbb-" trust preferred securities and "bbb-" preferred stock that are filed as part of its universal shelf registration. The rating outlook for all of the ratings has been changed to stable from positive. The financial strength rating of A- (Excellent) of Harleysville Life Insurance Company is unaffected; its rating outlook remains stable.

Published on October 17, 2003

These rating actions follow the recent announcement that the company would report a net loss for the third quarter 2003 and year-to-date due to loss reserve increases in several lines of business and the cost of claims resulting from Hurricane Isabel. Despite the losses, the rating affirmation reflects the company's strong capitalization, historical profitability and strong regional market franchise.

Offsetting these positive rating factors are A.M. Best's concerns with the operating results reported in 2003 and the potential for continued adverse loss reserve development. According to management, the loss reserve development stems from increased loss severity and different loss patterns since the recent reorganization of the group's claims operations.

Moreover, there is some additional uncertainty as respects to Harleysville's leadership and future direction due to the retirement of Harleysville's chairman and chief executive officer at year-end 2003. As a consequence, Harleysville will be without a permanent successor until a replacement is appointed. The change in outlook reflects these uncertainties and is contingent upon stabilization in prior year reserves and restored profitability.

Harleysville is afforded additional financial flexibility through its publicly-traded holding company, HGIC, which has access to the public markets. HGIC maintains modest financial leverage, which is enhanced by excellent cash coverage.
