Effective Thursday, September 9, 2010, we will introduce our new Market Data Notice format. As part of this introduction, we will also begin disseminating all market data communications from the CME Group Subscription Center, which gives you the ability to subscribe and unsubscribe to the Market Data Notices at your convenience. Please take a moment to complete the CME Group Market Data Notice registration form by Wednesday, September 8, to ensure that you continue to receive the most updated information affecting the CME Group Market Data community.
