Critical System Updates

Introducing Alphanumeric Host Order Numbers (HON)
Effective this Sunday, October 28, 2007, CME Group is launching alphanumeric Host Order Numbers (HON) in FIX tag 37, OrderID, in all applicable iLink messaging.

Alphanumeric values for tag 37 are currently available in the New Release environment. The following December 2007 futures are available with an alphanumeric HON in New Release:

NYMEX Crude Oil - CLZ7
E-mini S&P 500 ^® - ESZ7
Eurodollar - GEZ7
Euro FX - 6EZ7

Tag 37 is defined with a String format in the iLink Message Specifications module of the iLink Software Development Kit (SDK), so there is no field type change. Tag 37 is used to uniquely identify orders per contract, per trading session. Currently numeric only, tag 37 will use alphanumeric values to support the growth in trading and messaging volume.

Changes to Instrument Creation (MO) Replay Channels
Effective Sunday, November 18, 2007, CME Group is introducing new Instrument Creation (MO) Replay channels on the Market Data Platform in production. With these new channels, every product RLC data channel (e.g., channel 7, Equity futures; channel 8, Equity options, etc.) will have a dedicated MO Replay channel so customers can listen only to the MO messages for which they receive market data.

The current MO Replay channels (channel 1 and 16) will be maintained in parallel for at least eight weeks before those channels are decommissioned.

Please note, these changes only affect the RLC-format channels. There are no changes to the ITC 2.1-format channels.

The new MO Replay channels are currently available in New Release for customer testing. The new MO replay channels will be available in Certification on Wednesday, November 21. The channel definitions for New Release are now available at www.cme.com/certsdk.

ITC2.1 Market Data Platform Channel Changes
The legacy ITC2.1 Market Data Platform channels 4, 5 and 6 for CME Globex market data will be decommissioned on December 1, 2007.

Until December 1, the legacy ITC2.1 Market Data Platform channels will operate in parallel with the new ITC2.1 channels. The new channel schema, launched on Sunday, October 14, 2007, provides more granular and scalable ITC2.1-format market data. More information on this change and the new channels is available online.

Product Launches

U.S. Commercial Real Estate Futures
Effective this Sunday, October 28, 2007 (for trade date Monday, October 29), U.S. Commercial Real Estate futures will launch on the CME Globex electronic trading platform. Ten quarterly cash-settled contracts will be available upon launch: a national composite index, five geographic regional indexes, and four national property type indexes.

Based on the S&P/GRA Commercial Real Estate Indices (SPCREX™), these products will have a significant impact on how institutional and retail investors hedge and gain exposure to the U.S. commercial real estate market by expanding opportunities with investment choices by geography and property type.

Treasury Matched Mid-Curve Options
Effective Sunday, November 18, 2007 (for trade date Monday, November 19), Treasury Matched Mid-Curve (TOMMi) options on Eurodollar futures will launch on the CME Globex platform.

These options are part of the weekly mid-curve suite of Eurodollar options but have extended expirations to match the longer-dated Treasury options. Designed to meet the need for a mid-curve Eurodollar option that expires at the same time as the Treasury options, TOMMi options will eliminate the date mismatch between Treasury and mid-curve options. The matched expirations will also facilitate more precise volatility spreading with Eurodollar and Treasury options.

The CME Globex product code for these options is TE0 (t-e-zero).

Please note: CME Group will not list any weekly options that would expire on the same day as a TOMMi option.

The TOMMi options will launch on CME EOS Trader with a default clip size of "99999".

These options will be available in New Release for customer testing Monday, November 5.
