Great success of the Offer: SCOR would own 96.23% of Converium
To SCOR SE’s (“SCOR”) knowledge, as of July 26, 2007, SCOR would own 96.23% of Converium Holding AG (“Converium”).
As part of the additional acceptance period of SCOR’s public offer for Converium’s publicly held shares (“the Offer”), which opened on July 13, 2007 and was closed on July 26, 2007, 14,905,395 additional Converium shares have been tendered to the Offer, i.e. 10.16% of Converium shares, of which 3,732,335 Converium shares are in the process of being confirmed. Together with the 48,320,350 Converium shares already owned by the SCOR Group and the 77,937,316 Converium shares tendered during the initial period of the Offer, SCOR would hold 96.23% (93.69% excluding the Converium shares in the process of being confirmed) of Converium’s share capital in the aggregate. The definitive final result of the Offer will be published on August 2, 2007.
This preliminary final result confirms the success of the Offer and the support of a very large number of Converium shareholders for the combination of SCOR and Converium in order to create the fifth largest global multi-line reinsurer.
Subject to the applicable conditions subsequent set forth in the Offer prospectus published on April 5, 2007, as amended on June 12, 2007, the settlement and delivery of the Offer is scheduled to take place on August 8, 2007.
The general assembly of Converium shareholders will be held on 30 August 2007, in order to install the new Board of Directors of Converium as well as the new management structures. The SCOR Group, which is finalizing its new underwriting plan, will be fully ready in time for the Monte Carlo Rendez-Vous.
