Segment Overview

Market Making

Market Making segment income before income taxes increased 20% in the quarter ended June 30, 2009 compared to the prior quarter but decreased 30% from same period last year. Pre-tax margin was 65% in this quarter, down from 74% in the same period last year. Compared to the second quarter of 2008, this quarter presented a less favorable environment for market makers due to tighter bid/offer spreads on option exchanges. We managed our risk by continuing to avoid counterparty risks and balance sheet exposure from illiquid positions by making markets only in exchange traded products that are cleared through central clearing houses. Market Making options contract volume remained flat during this quarter compared to the same period last year.

Electronic Brokerage

Electronic Brokerage segment income before income taxes increased 5% in the quarter ended June 30, 2009 compared to the same period in 2008. This increase is attributable to strong customer account growth and trading activity over the prior year quarter, which more than offset lower net interest income, which was affected by historically low Fed Funds rates. Customer accounts grew 18% to 122,000 and cleared DARTs* increased by 11% to 317,000 in the quarter ended June 30, 2009 from the same period in 2008. Pre-tax margin increased from 48% to 51% for the quarter ended June 30, 2009. This improvement was primarily driven by a reduction in execution and clearing fees attributable to a reduction in customer volumes in futures instruments and higher rebates from exchanges with Make or Take pricing models.

*Daily average revenue trades (DARTs) are based on customer orders.
