Beginning on Monday, October 4, 2004, CME will launch its first two X-funds contracts.  To facilitate communication relating to the new listing of different X-fund futures contracts, we have created a web page that will be updated with pertinent information by 9:00 a.m. on the Friday prior to a Monday listing.

Included will be the X-fund listing dates and termination of trading dates, components, SPAN® initial and maintenance performance bond requirements, and prior final settlement price.  On Monday, October 4, 2004, the prior Final Settlement Prices will all be seeded to $100.00.  Subsequent listings will be seeded with the Final Settlement Price of the contract that expired the previous Friday.

The link to the web page is http://www.cme.com/wrappedpages/misc/xfunds.html.  Please bookmark this link; this web page will be updated every two weeks, as X-funds terminate and are replaced.

Additional information regarding X-Fund futures contracts can be found as follows:

For the primary Product page:  www.cme.com/xfunds.  On this page, you will find a thorough product description, in addition to links to an X-fund Futures Question and Answer paper, an X-fund calculator and a preliminary Special Executive Report, among other valuable links.
