SCOR considers A.M. Best’s decision unfounded

SCOR regrets A.M. Best’s decision to lower the rating of the Group at a time when the Group’s fundamentals are improving. Taking into account the following elements, SCOR considers A.M. Best’s decision unfounded:

• Operating cashflow rose strongly during the first half of 2003 to EUR 292 million vs. EUR 58 million for the same period last year,

• Combined ratios have improved significantly,

• The new underwriting policy, rigorous and selective, is producing results,

• The prudent asset management policy is producing increasing returns,

• The Group has discontinued its non-strategic activities (Alternative risk transfer through CRP, credit derivatives),

• The Group has decided to strengthen its capital base by bringing in investors into its Life reinsurance subsidiary, which is in the process of being created.

The Group is actively taking all the necessary steps to offer its clients the optimal level of security they expect from it.
