Currently, the MOS (Mutual Offset System) is temporarily unavailable every morning at 8:00 a.m., for approximately 20 minutes during Inter-Exchange reconciliation and balancing between the CME and SIMEX. On Monday, April 2, 2001, this processing window will start at 9:00 a.m. and will be in effect for the duration of Daylight Savings Time. We will revert to 8:00 a.m. when Central Standard Time goes into effect.

Please contact Client Management at (312) 930-3421, if you have any questions concerning this change.
