SCOR mobilized to help the populations
affected by the Tsunami

The SCOR Group has contributed 150,000 Euros to the aid campaign for victims of the Tsunami.

In addition to this aid, it has doubled the donations made by Group employees worldwide who organised a
spontaneous collection within the company.

The SCOR group has made a contribution to the international aid campaign for the populations affected by the South-East Asian Tsunami, with a donation of 150,000 Euros. This represents one per thousand of Group premiums in the area hit by the catastrophe. This donation has been directed to the UNICEF “South Asia Tsunami Relief Efforts” program.

In addition, the SCOR group is proud of the spontaneous mobilization of its employees who, due to their expertise and their profession, are particularly aware of the risks of natural catastrophes, the dramatic human losses and the destruction that these entail. The Group has matched Euro for Euro the donations collected by this campaign of its personnel, which will be directed to the UNICEF “South Asia Tsunami Relief Efforts” program.
