Reminder: Cabinet Pricing Change for CME FX and Commodity Options  
Effective Sunday, February 4, 2007, at customers' requests, CME will provide actual Cabinet prices for CME FX and Commodity outright options in all CME iLink order entry and RLC market data messages. With this change, orders submitted with a price below the Low Limit price, including a 0 (zero) price, will be rejected. Currently, in these products, outright option orders at a 0 price are treated as Cabinet orders.

The actual Cabinet prices will be broadcast in the Instrument Creation (MO) market data messages at position 625-643, Low Limit. The Cabinet values are currently available at www.cme.com/contractspecs.

The Cabinet pricing change will be available for customer testing in the certification environment this Monday, January 29.

Please note: there is no change to ITC 2.1 market data messages at this time, which will continue to reflect Cabinet trade prices as 0.

Reminder: CME Euroyen TIBOR Futures and Options Launch  
Effective Sunday, February 4, 2007 (for trade date Monday, February 5), CME Euroyen TIBOR futures and options will launch on the CME Globex platform. Electronically traded CME Euroyen TIBOR futures and options are identical to and fully fungible with the currently available floor contracts. Please note: these products have different Product and Instrument Group Codes, as detailed in the table below.

The Euroyen market has become more volatile in recent months and this is a particularly auspicious time to offer hedgers and traders even wider access to CME Euroyen contracts via CME Globex.

These new products are now available for customer testing in the certification environment.
