Dear CME Globex Customers,

Effective this Sunday, May 21, 2006, for RLC format market data messages, and Sunday, June 11 for ITC 2.1 format messages, to simplify and streamline customer processing of CME-listed spreads, CME is implementing new Spread Type values. These new values can be used to easily determine the spread type and associated listing conventions.

In the Instrument Creation (MO) messages, position 727-728, the following new Spread Type values will be implemented:

Spread Type Current Code Revised Code
Futures Calendar (CME Equity Futures Only) SP EQ
Futures Calendar (CME Foreign Exchange Futures, CME GSCI and CME GSCI ER Only) SP FX
Futures Calendar (CME HICP and CME CPI Futures Only) SP EC
Futures Pack HZ PK
Futures Bundle HZ FB
Futures Butterfly HZ BF
Futures Condor HZ CF
Futures Pack Spread HZ PS

These new Spread Type values are currently available for customer testing in the CME certification environment.

More information on MO messages and Spread Type values is available in the CME Market Data Platform RLC Message Specifications.

ITC Format
The following new Spread Type values will be implemented for ITC-format market data messages for both trading floor and electronically executed trades. Please note: all other calendar spreads will continue to use the "SP" Spread Type value.

Spread Type Current Code Revised Code
Futures Calendar (CME Equity Futures Only) SP EQ
Futures Calendar (CME Foreign Exchange Futures, CME GSCI and CME GSCI ER Futures Only) SP FX
Futures Calendar (CME HICP and CME CPI Futures Only) SP EC
