CME Only Financial Exchange Recognized for Technology Innovation and Leadership on InformationWeek 500

Wed Aug 23 2006

CHICAGO, Aug. 23 /PRNewswire-FirstCall/ -- CME, the world's largest and most diverse financial exchange, today announced that it has been recognized on the InformationWeek 500 list for the third consecutive year and is the only financial exchange on this year's list. The top 2006 InformationWeek 500 companies will be acknowledged at a gala awards ceremony held during the InformationWeek 500 Conference in Rancho Mirage, Calif., from September 10 - 13.

For the past 18 years InformationWeek has identified and honored the nation's most innovative users of information technology with its annual listing. The list is unique among corporate rankings because it spotlights the power of innovation in information technology, rather than simply identifying the biggest IT spenders.

"We are proud of our achievements in advancing our technology to the benefit of CME's customers worldwide," said CME Chairman Terry Duffy. "Today, electronic trading represents more than 70 percent of our volume, and we are the only exchange in the world to offer global market access to all major asset classes on a single platform."

"This award is a tribute to the outstanding employees at CME around the world and their dedication to innovation and implementing diverse technologies to deliver on the needs of our customers," said CME Chief Executive Officer Craig Donohue. "Our commitment to enhancing CME Globex®, the industry leading electronic trading platform that operates virtually 24 hours, allows us to strengthen our global leadership position in financial services as well as extend our offerings into areas outside of derivatives such as over-the- counter products and clearing services."

"The InformationWeek 500 honors today's leading companies who set the benchmark for business technology strategies and projects," said InformationWeek publishing director, Fritz Nelson. "The companies recognized on our list are some of the most innovative users of technology."

CME continues to research and add capabilities to its electronic trading platform, such as electronic options trading functionality and global telecommunication hubs, to broaden the distribution of its products around the world. CME operates virtually 24 hours every trading day and this past June began hosting NYMEX energy products on CME Globex. In May, the exchange announced a joint venture with Reuters to launch FXMarketSpace, the first centrally-cleared, global, over-the-counter foreign exchange (FX) marketplace, scheduled to launch in early 2007.
