Beginning November 9, 2007, electronic trading hours for mini-sized corn, soybean and wheat futures contracts will be extended. In addition, the mini agricultural contracts will trade electronically side-by-side with the grains and oilseed products already available in open outcry. These changes are expected to maximize access for global customers and increase opportunities for both electronic and floor trading.

Mini-sized corn, soybean and wheat futures were launched as Chicago Board of Trade products in April 2003 for floor trading and became available for electronic overnight trading in May 2007. The mini-sized futures will trade on e-cbot and then migrate to CME Globex in January 2008, when the majority of all of the electronically-traded legacy CBOT products will transfer to CME Globex, CME Group's electronic trading platform.

New Trading Hours

Electronic trading hours for the mini-sized corn, soybean and wheat contracts will be from 6:30 p.m. to 6:00 a.m. and 9:30 a.m. to 1:45 p.m., Central Time, Sunday through Friday. Electronic market makers will be added to the 6:30 p.m. to 6:00 a.m. trading hours to enhance liquidity during the Asian and European daytime trading hours.
