The Chicago Board Options Exchange (CBOE), the first and one of the world's largest options exchanges, announced further details for its upcoming IPO in an amendment filed this Tuesday. The exchange plans to offer 11.7 million shares, 2.1 million of which will be sold by insiders, resulting in 102.6 million shares outstanding post IPO. The initial price range was not disclosed. In addition to specifying the 17 new underwriters who will join sole global coordinator Goldman Sachs, the company also outlined plans to list on th NASDAQ under the symbol CBOE. Though a struggling broader market has resulted in a sluggish IPO market in recent weeks, CBOE's offering is likely to drive strong investor interest due to the success of past exchange IPOs such as those of the Chicago Mercantile Exchange (CME) and the IntercontinentalExchange (ICE). The deal is expected to price on June 14th and begin trading the following day.
