In December last year it was reported that, in accordance with the agreements relative to the creation of the joint venture alstom Hydro Holding signed in 2006, Bouygues has exercised its exit option to exchange its stake in alstom-hydro Holding for shares in Alstom shares, corresponding to approximately 1.5% of the share capital of the Company as of 31 October 2009.

Reuters reported that the European Commission was satisfied the planned transaction would not impede competition in Europe, and that it would not significantly change the market for hydro activities.
