The additional months extend the contract from June 2007.
Exchange President J. Robert Collins, Jr., said, "Participants in the natural gas markets have steadily increased their use of the natural gas basis swap futures contracts to manage their price risk at nearly 30 natural gas delivery points in North America. The addition of these trading months responds to feedback by market participants on the need for expanded risk management capabilities in the active underlying market. The Exchange will continue to evaluate listing additional contract months for its most active basis contracts on an ongoing basis."
