This represented a 63% increase over the previous year. The growth in trading was broadly distributed across TradeWeb's 13 global marketplaces. Of note, TBA-MBS (to be announced mortgage-backed securities) trading volume rose 74% to a record $15.2 trillion for the year. In the fourth quarter alone, $12.4 trillion in notional volume was executed over TradeWeb, a daily average of over $200 billion. In addition to the record volumes, TradeWeb welcomed 45 new Fixed Income trading desks, raising the total number that users can now access over the network to 192.

Among many milestones were the launches of U.S. Dollar and Euro Interest- Rate Swaps, U.S. Repo (tri-party repurchase agreements) and Global Credit Default Swap (CDS) Index marketplaces. Critical to the success of TradeWeb's Swaps and CDS launches were powerful trade processing capabilities that directly addressed a proven derivatives industry need. TradeWeb Repo is the first to offer commingled dealer electronic execution and trade processing capability to U.S. clients.

"We are delighted with TradeWeb's performance in 2005 and thank our clients and dealers for their continued support, which made this record year possible. As the world's leading online marketplace for fixed income, we will work hard to provide even better value for our clients in 2006," said Jim Toffey, Chief Executive Officer of Thomson TradeWeb.

"2005 was a strong year for TradeWeb, not just for the impressive volumes traded on our platform, but also because of the innovation we delivered to the market with the launch of new products - particularly in the derivatives space. Our European business continues to flourish as we add more clients to an already formidable customer base and we look forward to growing our product offerings and our client base as we continue geographic expansion in 2006," said Lee Olesky, President of Thomson TradeWeb.
