Changes to Instrument Creation (MO) Replay Channels  
Effective Sunday, March 30, 2008, CME Group will decommission the Instrument Creation (MO) Replay channels 1 and 16 in the production and Certification environments. Channels 1 and 16 will be decommissioned in New Release effective this Sunday, March 2.

The new MO Replay channels on the Market Data Platform, introduced in November 2007, allow customers to listen only to the MO messages for which they receive market data. With these new channels, every product RLC data channel (e.g., channel 7, Equity futures; channel 8, Equity options, etc.) now has a dedicated MO Replay channel.

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, Certification and production. The channel definition tables are available online for    Certification and New Release, and for    production.

Volatility-Quoted Options Launch  
Effective Sunday, March 9, 2008 (trade date Monday, March 10), volatility-quoted options are scheduled to launch on six FX options products: EuroFX, British pound, Japanese yen, Canadian dollar, Swiss franc and Australian dollar.

Volatility-quoted options support delta-neutral trading, which virtually eliminates the execution risk inherent to trading premium price options. The volatility-quoted options will utilize the existing FX options and futures products.

To simplify market data dissemination and processing, all market data for these new volatility-quoted options is segregated to new Market Data Platform channel 6. The market data for the equivalent premium legs is disseminated on channel 12, per current behavior. Information on the new channel is available in the   New Release Channel Definition table.

All of the volatility-quoted options suite, including all maturities in the American- and European-style, and Straddle, Strangle and Vertical strategies, are available in the New Release environment for customer testing. Customers can certify for volatility-quoted options in New Release via AutoCert+. This brief certification is mandatory for all systems that will provide trading access to these options.

FirmSoft Report Changes

In conjunction with the scheduled launch of volatility-quoted FX options on CME Globex on March 9, the report mode in FirmSoft will be updated to include the following new columns. These columns will be added to the right of all existing report mode data.

• Volatility
• Underlying Price
• Option Delta
• Risk Free Rate
• Expiration Time Value

If you have any questions or concerns regarding this change please contact your CME Globex Account Manager at 312.634.8700.

More information on these new products and the associated messaging and functionality enhancements is available in the    Volatility-Quoted Options Client Impact Assessment.
