News Releases

Paris and New York, 9 October 2008 - NYSE Euronext (NYX), the world's leading and most diverse exchange group, has introduced a global incentive program that increases efficiencies and produces cost-savings for high-volume trading customers whose orders are executed on the company's regulated European and U.S. equities markets. The global multi-platform incentive program, which is effective as of Oct. 1, 2008, enables high-volume trading customers to aggregate trading volume across six of NYSE Euronext's equities exchanges, thereby gaining additional value and benefits derived from the company's truly global marketplace.

"By rewarding our high-volume customers for trading across all of our market centers, we are enabling our customers to derive additional value from our global platform, and encouraging them to send more orders to our market centers," said NYSE Euronext CEO Duncan Niederauer.

Jean-François Théodore, NYSE Euronext Deputy CEO said, "These benefits will become even more apparent to customers as we roll out our Multi-Lateral Trading Facility and Universal Trading Platform in 2009. As this incentive program demonstrates, we intend to further extend the advantages of our global marketplace with new value-added initiatives for all NYSE Euronext customers."

NYSE Euronext cash equities exchanges include the New York Stock Exchange (NYSE), NYSE Arca and NYSE Alternext US (formerly the American Stock Exchange) in the U.S. and the Euronext exchanges in Amsterdam, Brussels, Lisbon, and Paris. Over 40% of the world's cash market trading takes place on NYSE Euronext's exchanges, and the exchange group's $155.9 billion average daily value of trading is nearly two and one-half times greater than any other exchange group in the world.

The underlying rates and volume tiers on NYSE, NYSE Arca and NYSE Euronext's European regulated markets remain unchanged.
