GDF SUEZ has sold all of its shares in the Belgian company SEGEBEL (50% of SEGEBEL) to Centrica. SEGEBEL holds a 51% share in SPE.

The transaction amounts to 515 million euros. A contingency payment could be made when the contracts between SPE and the Group go into effect following commitments made by the Group to the Belgian government.
