President and deputy CEO of NYSE Euronext Dominique Cerutti would become the new company's president and head of commercial and internal technology. Roland Bellegarde, also of NYSE Euronext, would become the head of European cash equities. The new company would potentially have 300 million euros (US$410 million) in cost savings. However, the merger would be subject to review in both the United States and European Union under concerns it could create a "de facto monopoly". NYSE Euronext shareholders approved the Deutsche Börse's all-stock deal on 7 July 2011, and Deutsche Börse shareholders had accepted the deal by 15 July 2011.
