Subject November 2005 Eurodollar Options to Expire on Thursday, November 10, 2005
Notice Date 2005-10-31
Notice Number Q2005-154
Effective Date 2007-10-31

As previously announced, the Trading Floor for CME® Foreign Exchange and Interest Rate Products will be closed on Friday, November 11, 2005, in recognition of the Veterans Day holiday.  Due to this Exchange holiday, all November CME® serial Eurodollar® options and serial MidCurve options will expire on Thursday, November 10, 2005.

Termination of trading of the expiring November 2005 Eurodollar options and MidCurve options will occur at 2:00 p.m. Central Time on the trading floor and at 4:00 p.m. on CME Globex® on Thursday, November 10, 2005.

The termination of trading times of the expiring CME November 2005 Eurodollar options and MidCurve options have een changed from the previously announced 12:00 noon close on the trading floor and 3:15 p.m. close on CME Globex, because the Bond Market Association (BMA) reversed its earlier recommendation to close early on this day.  The U.S. Treasury Department is conducting a 10-year note securities auction on that day as part of its quarterly refunding.  Therefore, the BMA is now recommending a full trading day  on Thursday, November 10, 2005.

CME November 2005 serial Eurodollar options and serial MidCurve Eurodollar options will not be available for trading on the CME Globex session starting at 5:00 p.m. on Thursday, November 10, 2005.
