Effective Sunday, July 31, 2005, CME Market Data Network (MDN) may disseminate CME Globex Eurodollar options instruments with a ¼ tick settlement price, even though the CME Eurodollar option instruments itself is not eligible to trade at less than a ½ tick.  This change will improve the accuracy of the CME MDN reporting of settlement prices for certain CME Eurodollar options instruments.  This change only affects RLC users subscribing to Channel 6.

This functionality is currently available for testing in the CME certification environment.
