Standard & Poor’s upgrades

SCOR Group to “A-, stable outlook”

SCOR Group is very pleased to announce today that the Group has regained its “A-, stable outlook” rating from Standard & Poor’s (“S&P”) Rating Agency, a rating that is considered ‘strong’ by S&P.

The return of the Group into the “A” rated category recognizes SCOR’s success of its recovery plan throughout the last two years and a half. It confirms the Group’s financial strength and high level of solvency. Today, based on its current level of capital, SCOR is well positioned to continue its disciplined underwriting approach on chosen markets and selected clients and pursue prudent investment strategies.

The SCOR Group extends its warm thanks to its loyal clients without whom this recovery would not have been possible.

The SCOR Group also extends its sincere thanks to its shareholders who have financed its re-capitalization through their continued support in capital increases. This continued confidence in the recovery plan is confirmed today. In turn, the Group is committed to providing continued shareholder value for the years to come.

The upgrading of SCOR Group to “A-, stable outlook” level will assist us in our risk selection process and focus on profitability in what already is a very competitive underwriting environment.
