September, 2007 is the 11th consecutive quarter of double-digit growth in volume, revenues and net income for ISE. International Securities Exchange Holdings (ISE) recorded a proforma net income of $25.0 million and proforma diluted earnings per share of $0.62, excluding costs related to the pending merger with Eurex. The average daily trading volume increased by 53.0% to a record 3.4 million equity and index options contracts. The GAAP pre-tax margin was 47.9% and proforma pre-tax margin was 64.7% for the options exchange.

David Krell, president and CEO of ISE, said: Our record trading volume and profitability were fueled by the volatility in the financial markets and the operating leverage in our business. We are gaining traction in our recent new business initiatives, including our foreign exchange offering, ISE FX Options, and our Second Market.
