CBOE Announces Filing Of S-4 Registration Statement

The Chicago Board Options Exchange announced today that its Board of Directors authorized the filing with the Securities and Exchange Commission (SEC) of an S-4 Registration Statement that will set forth the terms of its proposed demutualization transaction. CBOE expects to submit this filing to the SEC in the next two weeks. CBOE's proposed demutualization is subject to regulatory approval by the SEC and a vote of the CBOE membership.

CBOE is currently a mutually-owned membership organization. In its proposed demutualization, CBOE will become a wholly owned subsidiary of a new holding company, CBOE Holdings, Inc. CBOE memberships existing at the time of the demutualization will be converted into shares of CBOE Holdings.

"This is an historic step for CBOE, where we have paved the way for a successful CBOE demutualization by streamlining our membership structure, cutting costs, and increasing profitability. The filing of our S-4 is an important next step toward reaching our ultimate goal to operate as the most successful options exchange in terms of customer and shareholder satisfaction," said William J. Brodsky, CBOE Chairman and CEO.
