UBS brings to TradeWeb's new corporate bond marketplace deep liquidity in a wide range of investment grade corporate bonds. It joins six other major corporate bond dealers, including Citibank, Goldman Sachs, JPMorgan, Lehman Brothers, Merrill Lynch, and Morgan Stanley in providing liquidity for more than 150 of the largest and most active credit investors.

With UBS joining TradeWeb's corporate bond platform, investors now have access to the dealers that collectively managed nearly 75% of the year-to-date high grade new issue volume according to Thomson Financial (NYSE: TOC; TSX: TOC) and 75% of the secondary trading volume as reported by Greenwich Associates.

"As dealers and their customers come to fully appreciate TradeWeb's superior design, content, and economics, the choice to participate is very compelling," said Jim Toffey, CEO of TradeWeb. "Like with every other asset class we have online, we build a platform that leap frogs the competition's current offering."
