Liquidnet Announces Enhancements to the Liquidnet Select Program

New York, June 8, 2009 – Liquidnet, the global institutional marketplace, today announced the launch of the Liquidnet Select CSA Online Portal, a new and enhanced functionality specifically designed for its buy-side Member community. The CSA Online Portal, Liquidnet Select Online, is a robust and efficient Web-based portal, and the latest feature to be introduced to the Liquidnet Select program. Liquidnet Members are now able to efficiently and effectively manage their accounts, and pay the bills associated with their trading activity. This new offering is available to Liquidnet Members in the U.S. who are eligible to participate in commission sharing and similar arrangements, including Liquidnet’s own CSA, Liquidnet Select.

“We have always been focused on providing our Members with the most innovative and comprehensive services available,” said Seth Merrin, Liquidnet’s Chief Executive Officer. “In light of the challenges in today’s financial markets, we want to ensure that our Members are best equipped to maximize and manage their businesses. Our Liquidnet Select program helps them meet these objectives. With the recent enhancements to our CSA program, our Members are able to receive best execution and manage their expenses,” said Merrin.

As part of Liquidnet’s CSA program, a certain percentage of trading commissions is credited to participants’ CSA accounts. Member and non-Member customers are also allowed to add additional amounts to Liquidnet’s standard commission rate, which are credited to their CSA accounts. Customers are then able to use the funds in their CSA accounts to pay for certain services, including third-party research from third-party providers. Currently, there are over 400 vendors that are part of the Liquidnet Select program.

Liquidnet’s CSA programs increase the buying power for its customers, and maximize their commission credits. Under the program, Liquidnet offers discounts on a variety of services, including the recently announced corporate access initiatives. The launch of the Liquidnet Select CSA portal will further enhance the CSA program, and expedite the processing and payment of CSA invoices, while enabling Liquidnet Members to track their commission credit on trades. No administrative fees will be charged for the program and Liquidnet plans to implement the CSA Online Portal globally by the end of the third quarter of 2009.

“The recently introduced CSA Online Portal is robust, easy to navigate and will save our members a great deal of time in managing their accounts,” said Rich Stein, Executive Vice President. “Our CSA program will expedite the processing and payment of invoices, and enable our members to monitor their accounts in a timely manner. This is yet another benefit that we offer to all members who trade at Liquidnet.”

The Liquidnet Select CSA portal was developed in conjunction with Firm58 (https://www.firm58.com), the leader in on-demand post-trade management software.
