Revenues from U.S. operations were $81.9 million in the second quarter of 2012 compared to $93.9 million in the second quarter of 2011.  ITG’s U.S. operations posted a GAAP net loss of $220.9 million in the second quarter of 2012 and adjusted net income of $0.4 million in the second quarter of 2012, compared to a GAAP net loss of $196.3 million and adjusted net income of $3.7 million in the second quarter of 2011.  Sell-side client volume represented 50% of total U.S. volumes, up from 48% in the first quarter of 2012.

“Depressed levels of overall institutional trading activity in the U.S. and lower market turnover in all of our international regions significantly impacted our profitability in the second quarter,” said Bob Gasser, ITG’s Chief Executive Officer and President.  “Despite the higher percentage of sell-side volume, our overall average U.S. revenue capture has remained steady for the past few quarters, demonstrating the value our products, including research, deliver to our institutional clients.  In the face of these challenging conditions we remain focused on disciplined expense management, improved operating leverage through POSIT® and a continued share buyback program.”
