To support the rollout of additional options contracts on the CME® Globex® electronic trading platform, the ISIN codes for
several instruments will be changing. The ISIN code is the 12 character alphanumeric identifier for each instrument listed
on the CME Globex platform and can be found in positions 1 through 12 of all contract-specific CME Market Data RLC-formatted
messages (Channel 4 of the Market Data Network (MDN)). CME recommends that customers clear the ISIN codes from existing product
tables and reacquire the ISIN codes from the CME MDN MO (m-oh) message on a weekly basis.
These changes will be reflected in the CME production environment market data feeds beginning Sunday, May 1, 2005, and will
impact the following products:
·CME E-mini S&P 500® options and options spreads
·CME E-mini NASDAQ-100® options and options spreads
·CME E-mini Russell 2000® options and options spreads
·CME Euro FX options and options spreads
·CME Japanese Yen options and options spreads
·CME S&P 500 options
·CME NASDAQ-100 options
·CME S&P 500/Barra ValueTM options
·CME S&P 500/Barra GrowthTM options
