London, Paris, 19 July 2011

NYSE Euronext today announced the extension of its range of indices into the commodity asset class with the launch of four single commodity indices based on its NYSE Liffe Milling Wheat Futures Contract and Cocoa Futures Contract respectively.

The new single commodity indices will measure the performance of a strategy which consists of investing in the most active delivery month of the relevant Futures Contract, measured by level of open interest. When the expiry date of this delivery month approaches, the investment is rolled into the next most active delivery month. The indices offer investors an easy way to track the NYSE Liffe commodity markets, and will be calculated both on an excess return basis and a total return basis.

“The launch of these indices extends NYSE Euronext’s index range to include the commodity asset class and facilitates new opportunities for market participants to track and offer products on NYSE LIFFE’s specific commodity futures,” says George Patterson, Head of NYSE Euronext’s Global Index Group.

Ian Dudden, NYSE Liffe’s Director of Commodity Derivatives, added: “The launch of these new indices comes at a very exciting time in the history of the underlying contracts, with NYSE Liffe’s commodity portfolio continuing to experience record growth in both volume and open interest during 2011. These indices will allow the development of new products giving investors the opportunity to gain exposure to these important benchmark contracts.”

These new indices have been calculated and disseminated in real-time since 14 July 2011 and can be identified as follows:
