CHICAGO -- The Antitrust Division of the U.S. Department of Justice has sent a request for additional information ("Second Request") to Chicago Mercantile Exchange Holdings Inc. regarding CME's proposed merger with CBOT Holdings Inc.

CME anticipated receiving a second request, which is not uncommon in major transactions. CME said it is working closely with the Department of Justice and plans to cooperate fully and to respond promptly to its request.

Pending approvals by regulators, and shareholders of both companies and CBOT members, as well as completion of customary closing conditions, CME continues to expect the transaction to close by mid-year 2007.

"The combined company, to be named CME Group Inc., is expected to transform global derivatives markets, creating operational and cost efficiencies for customers and exchange members, while delivering significant benefits to shareholders," said CME Executive Chairman Terry Duffy.

Craig Donohue, CME CEO, said: "Growth in the global derivatives industry is accelerating and new competitors are emerging in exchange, over-the-counter and other unregulated markets. As a combined company, we will be better positioned to capitalize on these trends and compete more effectively as our industry continues to transform."

Chicago Mercantile Exchange Holdings Inc. is the parent company of Chicago Mercantile Exchange Inc., the world's largest and most diverse financial exchange. As an international marketplace, CME brings together buyers and sellers on the CME Globex(R) electronic trading platform and on its trading floors. CME offers futures and options on futures in these product areas: interest rates, stock indexes, foreign exchange, agricultural commodities, energy, and alternative investment products such as weather, real estate and economic derivatives.
