Robert GreifeldThank you, John. Your introduction will become longer than my comments soon enough. For the second quarter of 2012, our non-GAAP exchange revenues were $413 million, down slightly to the -- compared to the $415 million in the prior-year quarter but up 3% when you exclude the net impact of acquisitions and the foreign currency charges. Our non-GAAP EPS was $0.64, up $0.02 compared to the prior-year quarter. This performance was achieved with a significant currency headwind. If exchange rates had held constant with prior-year levels, our non-GAAP EPS would have been $0.03 higher, tying our all-time record. Given the weak trading volumes we are experiencing, this is a strong performance. We continue to see good growth on our non-transaction driven businesses, which are mainly recurring and subscription base. These revenues totaled $291 million and were up 4% compared to the second quarter of 2011. This growth was the result of 8% revenue growth in our global market data business. Access and brokerage services continue to perform well, up 12% driven by our new technology introductions. Our transaction-based businesses, equity and option trading in the U.S. and Europe, saw relatively weak volumes compounded by a weakening euro. Currency reduced our second quarter 2012 transaction revenues by $5 million year-over-year.
