Wall Street Systems Connects To Markit For Enhanced Credit Trading

New York and London, 19 September 2006 - Wall Street Systems, the leading provider of global treasury and capital markets solutions and services, today announced it has integrated Markit Group Limited's (Markit) Credit Default Swap (CDS) and Corporate Bond price data together with Markit RED (Reference Entity Database) for reference entities and obligations within The Wall Street System. The combined solution will enable clients of Markit and WSS to utilize an enhanced credit trading and risk management solution using the best data sources in the market.

Markit is the leading industry source of independent pricing, reference data, portfolio valuations and OTC derivatives trade processing for the global financial and commodities markets. Markit's CDS price data has been integrated within The Wall Street System, which brings together support for interest rate and credit derivatives to enable banks to create; price, process and risk manage new deal structures using their own models and software with total confidence and complete independence from Wall Street Systems. The partnership will provide financial institutions with greater automation in the trading of credit derivatives, thereby reducing risk by lowering the number of failed trades from inconsistent data. The seamless delivery of Markit data on the robust Wall Street Systems platform will allow clients the flexibility to increase credit trading activity whilst building volume growth. This integration will bring immediate value by improving straight-through processing rates and operational efficiency through the single system.

Larry Ng, managing director of product and marketing at Wall Street Systems said, "This new offering is a major advance in the ability to manage complex products and their inherent risk. We are pleased to be working with Markit, the industry standard for reference entity and reference obligation identifiers used throughout the credit derivatives marketplace today. Our clients will benefit from a comprehensive view of complete and accessible data which increases trading efficiency and reduces risk and complexity for trade processing."

Wall Street Systems is widely recognized as one of the market leading providers of treasury and capital markets solutions to a wide range of financial institutions and major-multi national corporations. With solutions that span global back office, foreign exchange, treasury and cash management, Wall Street Systems is perfectly positioned to meet the infrastructure needs of the financial world.

Mark Hunt, Director, Product Development at Markit said, "The dramatic growth and ever-changing landscape of the credit markets means that customers demand integrated access to quality data within mission-critical systems to better support the key trading, risk and operational processes required by business today. The combination of Wall Street Systems' proven cross-asset, front to back office solution architecture and Markit's mark-to-market price and reference entity data will bring significant added value to our mutual customers."
