— 49 Million Shares* Traded per Day

BIDS Trading Reports Record Trading Volumes for May 2010

NEW YORK, NY – June 3, 2010 – BIDS Trading, the alternative trading system (ATS) designed to increase liquidity in the U.S. equity block trading market, reported record levels of liquidity for the month of May 2010.

BIDS Trading’s average daily volume of 49 million shares* in May represents a 118% increase from May 2009. BIDS Trading also achieved an all-time single day record in May, trading over 90 million shares.* The dark pool reached another milestone in May, trading over one billion shares in a single month.

The dark pool’s rapid growth can be attributed to its unique liquidity offering. Institutional traders can anonymously interact with liquidity from its buy-side user base as well as sell-side algo order flow re-aggregated into block-sized trades.

The use of non-displayed, electronic block trading venues, such as BIDS Trading continues to rise. “A trader’s ability to control their order and manage pre-trade information leakage is vital when executing large, complex blocks of stock,” said Tim Mahoney, CEO of BIDS Trading.

“We are thrilled to see our volumes and user base grow each month,” said Mahoney. “As we expand our reach, we continue to perfect our pre-trade information controls and post-trade analytics of the effects of those controls – all leading to BIDS’ becoming a critical tool on the buy-side trader’s desk.”

BIDS Trading participants have simultaneous access to both the BIDS ATS and the New York Block Exchange (NYBX). NYBX, a revolutionary joint venture between BIDS Trading and NYSE Euronext, allows non-displayed liquidity to anonymously access both the displayed and reserve liquidity of the NYSE order book, creating an innovative platform to re-aggregate blocks of stock.
