Options exchange operator CBOE Holdings Inc (CBOE.O) reiterated in a regulatory filing on Wednesday that it may selectively explore acquisitions or strategic alliances, and may incur debt or issue additional equity to do so. The same language was used in the company's previous regulatory filings but could have new meaning amid a global exchanges merger mania. In a spate of deals last month, Deutsche Boerse AG (DB1Gn.DE) bid for NYSE Euronext (NYX.N), London Stock Exchange (LSE.L) offered to buy Toronto Stock Exchange parent TMX Group Inc (X.TO), and U.S.-based BATS Global Markets bid for fellow private venue operator Chi-X Europe.
