Exchange to Transition e-miNYsm Futures Contracts to NYMEX ClearPortsm

Fri Apr 01 2005
NEW YORK, N.Y., April 1, 2005 — The New York Mercantile Exchange, Inc., will transition its e-miNYsm crude oil and natural gas futures contracts to the NYMEX ClearPortsm trading platform as the NYMEX miNYsm energy futures contracts on Monday, June 20, 2005, at 3:15 PM New York time.

These contracts will no longer be available for trading on the Chicago Mercantile Exchange's GLOBEX® trading platform after the close of the Monday, June 20, 2005, trading session, which ends at 2:30 PM New York time.

Exchange President James E. Newsome said, "These contracts continue to be successful complements to our traditional crude oil and natural gas futures and options contracts. They appeal to additional energy market participants, offering an alternative way to participate in these dynamic markets and have played an increasingly important role in market participants' trading strategies since they were launched nearly three years ago. This consolidation of the NYMEX miNYsm energy futures contracts onto NYMEX ClearPortsm gives our customers access to a broad range of risk management tools from a single electronic platform."
