On June 18th, the SEC provided notice of the Chicago Board Options Exchange's ("CBOE") filing of a proposed rule relating to the distribution of auction messages. The proposal would make more consistent the provisions in CBOE's rules regarding who is eligible to respond to auction messages. It would allow all Trading Permit Holders to respond to SAL, HAL2 and COA auction messages in certain classes designated by the CBOE and that Trading Permit Holders may redistribute auction messages in these classes. Comments should be submitted on or before July 13, 2012. SEC Release No. 34-67209.
