Press release of June 10, 2005
*************
Project NEW SCOR

The SCOR Group today announced a plan for adapting its worldwide structures to its new business profile, which has now been stabilised.

The New Scor project notably proposes the creation of a 100% owned subsidiary – following the example of the Life reinsurance subsidiary created in 2003 – combining all Non-Life reinsurance business, as well as business relating to treaties and large corporate risks. Similarly, the Group’s network of various subsidiaries will be streamlined.

This global project aims to restore the Group’s competitiveness with regard to its competitors, to improve its operational performance and to achieve the objective of a cost ratio of 5% of written premiums between now and the end of 2007, as set out in its “Moving Forward” plan adopted by the Group’s Board of Directors in August 2004.

The “Moving Forward” plan sets out two scenarios for the SCOR’s business development between now and the end of 2007 , in accordance with changes in the reinsurance business cycle across the world. In order to ensure the Group’s competitiveness, the reduction in costs between now and the end of 2007 should be in the order of between EUR 24 million (fragmented scenario) and EUR 44 million (downward scenario).

Today SCOR’s Management presented to SCOR Paris’ work council a solution according to which this reduction be divided 50/50 between a reduction in structural costs and a reduction in total wage bill. The possible contraction of structural costs between now and the end of 2007 on a worldwide level would thus be between EUR 12 and 22 million depending on the Group’s business developments. The corresponding contraction of total wage bill between now and the end of 2007 would also be between EUR 12 and 22 million according to these two scenarios, which would represent a reduction on a Group level that could involve up to 220 positions across the world on the basis of staff numbers at the end of 2004.

A method agreement will be negotiated between now and mid July in order to fix the methods and the timetable for dealing with the consequences for employees in France of the implementation of this project, including a redundancy plan prioritising voluntary redundancy.
