SLPs contribute to the Liquidnet H2O liquidity pool, which averaged 10.2 billion shares per day in March 2009.

SLP liquidity also advanced Liquidnet's Supernatural orders product, which accesses Liquidnet's H2O and natural liquidity pools, as well as external markets, to achieve a 49% percent crossing rate in March 2009.

"Our partnership with OES MarketGroup will enable us to further build our global institutional marketplace," said Jay Biancamano, Liquidnet Global Head of Marketplace. "When you can offer the buy side a single venue that completes approximately half of its executions internally and without the need to expose orders to the public market, you have essentially created a value proposition that is unsurpassed in today's markets. As a result, Liquidnet Members and SLPs are able to interact with liquidity that cannot be found on the open market."

"We are delighted to enter into this partnership with Liquidnet to interact with our growing network of exchange and broker-dealer liquidity approaching two billion shares of actionable order flow per day," said Mike Barth, OES MarketGroup EVP. "Our partnership demonstrates our commitment to aggregating complementary liquidity to provide our clients with the maximum level of liquidity and quality execution." Does OES aggregate our liquidity?

Based in part on the participation of SLPs, Supernatural orders increased 181% to 26.6 million shares from 9.5 million shares (Mar '09 v Mar '08) and accounted for 42% of total trading volume in March 2009, versus 14% in March 2008. Supernatural trading strategies are designed to execute block-sized trades with natural matches when available, and react quickly to absorb liquidity from other sources.
