October 12, 2009

Since CME Group completed its acquisition of NYMEX Holdings, Inc. in August 2008, the Exchange has been actively integrating NYMEX business operations. We are pleased to announce that internal work has been completed and we will now provide a single Web site containing valuable information on all of our products and services. The timing for decommissioning nymex.com is early November 2009. As we move closer to that timeframe, we will provide any updates to the timing.

Following the nymex.com decommissioning, your existing bookmarks will be redirected to the corresponding pages on cmegroup.com. Please remember to bookmark these new pages to easily find the information upon your return visit.

In addition to the information listed above, please note that the legacy NYMEX settlement file located at http://www.nymex.com/md_ewd.aspx will be migrating on October 30, to the same format as the CME Group standard settlement files, which can be found at http://www.cmegroup.com/market-data/settlements/. Until that time, the NYMEX and COMEX links will lead back to the existing nymex.com pages. To prepare for the impending change in settlement data display on cmegroup.com, please refer to any of the other products listed at http://www.cmegroup.com/market-data/settlements/ and use them as a template for the treatment of energy and metals settlement data after October 30.

We appreciate your support as we move to a single Web site and continue to improve cmegroup.com to meet your needs.

Please be advised that effective Monday, October 12, 2009, the Exchange will amend the listing of strike prices on COMEX Gold Options Rules (Rule 115.03; code OG) listed for trading on CME Globex and the NYMEX trading floor, respectively, and for clearing through CME ClearPort. Specifically, the Exchange will change the strike price to $5.00 increments for all trading months regardless of the level of the underlying futures prices. Currently, the strike price interval is dependent on futures price levels as follows: $5.00 if futures prices are under $500; $10.00 if futures prices are between $500 and $1,000; and $25.00 for futures prices above $1,000.

In addition, the number of listed strike prices above and below the at-the-money option will expand from six to twenty strike prices.

For more information, please contact Bob Biolsi, at (212) 299-2610.
