NYMEX Clearing and Non-Clearing Member Firm CME Group Class A Shareholding Requirements Update
As you were previously notified in Notices 08-415 and 449, CME Clearing instituted a safe harbor for NYMEX firms to meet the shareholding requirements set forth below.

The deadline for the safe harbor which was set to expire on Thursday, September 4, 2008 has been extended until Wednesday, September 17, 2008 in order to provide firms with additional time to increase their shareholdings to meet the requirements.
