William J. Brodsky Thanks, Debbie. Good morning and thank you for joining us today. It is my pleasure to report another very positive quarter at CBOE Holdings, where we delivered our eighth consecutive quarter of adjusted earnings per share growth and made significant year-over-year gains in market share. Our strong performance in multi-listed products, our ability to leverage proprietary products and a prudent approach to cost management enabled our company to achieve solid financial results despite lower industry-wide trading volume. CBOE Holdings continues to generate and return enhanced value to our stockholders. We are especially pleased with our board's recent action to increase our quarterly dividend by 25% and to increase our share repurchase program by $100 million. My remarks today will focus on progress made in the quarter on our key strategic initiatives for 2012: product development; optimizing revenue in commoditized products; broadening our customer base; and leveraging our state-of-the-art trading technology.
