CME Group Only Financial Exchange Recognized CHICAGO, June 15 /PRNewswire-FirstCall/ -- CME Group, the world's largest and most diverse derivatives exchange, today announced that it has been selected by IDG's Computerworld, the "Voice of IT Management," as one of the top workplaces for information technology (IT) professionals for the fifth consecutive year. This honor is part of the weekly IT publication's 16th annual Best Places to Work in IT survey, which was published in the June 15 issue and online at http://www.computerworld.com/. CME Group is the only financial exchange to receive this honor. The Best Places to Work in Information Technology (IT) list is an annual ranking of the top 100 work environments for technology professionals compiled by IDG's Computerworld, the "Voice of IT Management." The lists are compiled based on a comprehensive questionnaire regarding company offerings in categories such as benefits, diversity, career development, training and retention. In addition, Computerworld conducts extensive surveys of IT workers, and their responses factor heavily in determining the rankings. "We are honored to receive this award and acknowledge the great work our team does to advance our reputation as a leading technology provider," said CME Group CEO Craig Donohue. "Thanks to their efforts, we facilitated the trading of three billion contracts representing $1.2 quadrillion in notional value last year. Our strong focus on technology continues to transform our business and enable us to pursue new growth opportunities in listed and over-the-counter markets, and we look forward to enhancing our capabilities even further in the years to come." "Providing best-in-class customer service remains at the core of everything we do, and we want to thank our technology team for their commitment to providing cutting-edge technology across all areas of our business," said CME Group President Phupinder Gill. "Given the current market environment, we are especially proud of the technology that supports our clearing services and improves our clients' ability to manage their risk." Some of the factors that contributed to CME Group's recognition by Computerworld included the following: -- Electronic trading represents approximately 80 percent of CME Group's total volume to date in 2009, versus only 15 percent in 2000. In that same timeframe, average daily total volume has grown more than ten-fold from 917,000 to 10.4 million contracts traded; CME Group is the only financial exchange in the world that operates virtually 24 hours every trading day, which means every aspect of the exchange is driven or supported by technology; and, -- CME Globex offers global access to the widest range of benchmark products across all major asset classes - a full range of commodity, economic event, energy and metal, equity index, foreign exchange, interest rate, real estate and weather products. The exchange's technology team is charged with continuously enhancing the system's speed, reliability and scalability to support our ongoing growth and customer demand. CME Globex handles an average of 8.2 million contracts per day with an average current response time of eight milliseconds. "To be among the Best Places to Work in IT, it's not enough just to seek out and hire the most talented IT people, offer them competitive pay and provide great benefits," said Scot Finnie, editor in chief of Computerworld. "The organizations that made this year's Best Places to Work list sustain a dynamic work environment in which IT professionals keep their hands on the latest technologies and work on projects that are business critical. In the months and years ahead, IT is going to become a key accelerator of business growth."
