The shareholders of NYSE Euronext have voted to extend by two years the tenure of Jean-François Théodore as the deputy chief executive of the transatlantic exchange group formed last month.

The exchange group said it had always been the plan to put to shareholders the extension of his contract at yesterday's meeting in Amsterdam, which also confirmed the appointment of John Thain, the chief executive of NYSE Euronext, to the supervisory board of the Euronext NV, the European business of NYSE Euronext.
