CME and SGX Renew Landmark Mutual Offset System Agreement

Mon Oct 30 2006

CHICAGO and SINGAPORE, Oct. 30 /PRNewswire-FirstCall/ -- Chicago Mercantile Exchange Inc. (CME) and Singapore Exchange (SGX) are pleased to announce the renewal of their Mutual Offset System (MOS) agreement for an additional three years beginning February 2007 to run through 2010. This extension of the agreement reinforces the importance and benefits of the mutual offset arrangement to both exchanges and the global derivatives marketplace.

The MOS gives market participants the choice of clearing certain products at either CME or SGX. Currently these include: Three-Month Eurodollar Futures, Three-Month Euroyen Futures and yen-denominated Nikkei 225 Index Futures. New products launched by CME and SGX will also be considered for inclusion in this agreement.

"The MOS was a landmark agreement when we first signed it more than 20 years ago. We are pleased to be able to extend this important alliance with SGX for the benefit of Eurodollar traders throughout Asia," said CME Chairman Terrence A. Duffy.

"The renewal of this agreement is an important part of our continued growth in Asia," said CME Chief Executive Officer Craig S. Donohue. "Through this partnership, we will extend the mutual offset system benefits of real- time clearing and inter-exchange transfer services, allowing market participants to execute their risk management programs in an effective and timely manner."

SGX CEO, Mr. Hsieh Fu Hua said, "We are very pleased to strengthen our longstanding partnership with CME through the innovative mutual offset link. This arrangement enhances round-the-clock trading of leading interest rate and stock index products by giving market participants the ability to clear trades in their own time zone. Market feedback indicates this is an important feature and I am glad that we can continue to make it available."

The close partnership between CME and SGX began in 1984 when the first MOS agreement was signed. This international agreement remains the longest and most successful between two derivatives exchanges.
