Investment Technology Group Announces POSIT Alert in US

Business Wire, July 31, 2008

NEW YORK -- Investment Technology Group, Inc. (NYSE: ITG), a leading provider of technology-based trading services and transaction research, today announced that it will become full owner of BLOCKalert, acquiring Merrill Lynch's stake in the joint venture.

The block crossing service will be re-branded as POSIT Alert and merged into ITG's POSIT crossing suite, providing POSIT Alert clients with a more seamless interface. POSIT Alert is now available under the same brand name in the US, Europe and Australia, unifying ITG's strong global POSIT brand.

"ITG's neutral agency broker status and trusted POSIT crossing suite have long been key differentiators for the firm," said Bob Gasser, CEO and President of ITG. "After a thorough evaluation of our global POSIT crossing suite, we felt that clients would benefit most if ITG focused on enhancing the system with direct buy side to buy side liquidity."

"Merrill Lynch's joint venture with ITG was a positive experience for both firms and we look forward to continuing our relationship with ITG," said Michael Stewart, managing director and head of global cash equities at Merrill Lynch.

BLOCKalert averaged 10.4 million shares a day in the first half of 2008 and had an average execution size of 41,000 shares. As the transition is completed, POSIT clients can expect the same high quality and anonymous block crossing service that they have come to expect from ITG.
