Please note that constituents of Standard & Poor's Indices will not be affected by NYSE Euronext's implementation of the Single Order Book concept for the markets of Amsterdam, Brussels and Paris. The Single Order Book concept will not be implemented for the Lisbon market. In the Single Order Book, multi-listed securities will be traded on one Market of Reference (MoR). All S&P index constituents in these Euronext markets trade on the Market of Reference and hence are not affected by this consolidation into one Universal Trading Platform. For more information on the Euronext Single Order Book and ESES, please refer to
