      Exchange Rules call for the limits to be re-calculated quarterly at the close of business on the day preceding the commencement of a new calendar quarter. Note that stock index price limits are generally revised upwards from the limits that were in force during the previous calendar quarter.

      The Exchange’s price limits are re-assessed quarterly rather than established at fixed levels insofar as fixed limits are not responsive to on-going market fluctuations. CME Rules are designed to coordinate with circuit breaker provisions as applied by the New York Stock Exchange (NYSE).

      The NYSE enforces limits at 10%, 20% and 30% declines of the Dow Jones Industrial Average (DJIA), calculated at the beginning of each calendar quarter, using the average closing value of the DJIA for the prior month, rounded to the nearest 50 points. Limits in force during the current quarter are 1,350, 2,700 and 4,000 (limits were at 1,350, 2,700 and 4,050 index points during the previous calendar quarter).

      The merger between CME and CBOT means that Dow Jones Industrial Average (DJIA) futures are now an important component of the CME Group’s roster of benchmark stock index products.Effective as of January 13, 2008, new daily price limit Rules for all CBOT domestic index products will be 10%, 20% and 30% for regular trading hours (RTH) and 5% for electronic trading hours (ETH). Limits are as follows:

      Contracts 5% Limit 10% Limit 20% Limit 30% Limit
      DJIA Futures

      650.00

      		 1,350.00 2,700.00 4,000.00
