Beginning Sunday, November 14, 2004, all pit and electronically traded Eurodollar Serial, Quarterly, Mid-Curve and 5-year Bundle options will be eligible to trade in increments of .005 (1/2-tick), under new rules.  However, the nearest expiring regular quarterly options on CME Eurodollar futures contracts will still be eligible to trade in increments of .0025 ($6.25) if the underlying quarterly future is eligible to trade in quarter-ticks. 

The attached table illustrates this change.

Thank you.
