CBOE Statement On SEC Administrative Proceedings, June 11, 2013

Our ability to work effectively and cooperatively as co-regulators with the SEC is central to our role as an SRO. In addition to working proactively with the SEC throughout its investigation, we voluntarily launched our own exhaustive, internal assessment of regulatory and compliance practices across our entire organization, assisted by third-party consultants and independent outside counsel. All actions either required or recommended by the SEC, as well as those resulting from our rigorous self-review, have been or are now being implemented. This settlement marks a significant step in putting the SEC matter behind us, but our commitment to maintaining the very highest standards in regulation and compliance will be carried forward throughout our organization.
