  Methodology for Reporting Third-Quarter Results

Group was formed on July 12, 2007, at the completion of the merger of CME and Chicago Board of Trade. For the purpose of quarterly reporting, third-quarter 2007 volume is calculated using CME standalone volume through July 12, 2007, plus the combined volumes of CME and CBOT for the remainder of the quarter, and is compared with the third-quarter 2006 using the same methodology. This methodology also is the basis for calculating transaction fee revenue for the third quarter. Following is a breakdown of this comparison by product line.
