Los Angeles, CA, April 3, 2000 - Capital Management Sciences, a division of Data Broadcasting Corporation (Nasdaq:DBCC), announced the addition of an online resource of mortgage-backed securities data to its fixed income system, BondEdge. The new database contains historical factors and prepayment data, geographical breakdowns and collateral detail for over one million fixed and adjustable rate mortgage pools and CMO tranches. Similar content will be made available for asset-backed securities in the near future.

“This detailed descriptive data can be used in conjunction with the analytical tools in the BondEdge system, such as total return simulations and what-if analyses,” explained Teri Geske, senior vice president of product development at CMS. “The prepayment history and geographic distribution of mortgages underlying a particular pool can help investors to assess future prepayment risks and to compare similar pools at a more detailed level.”

The data is accessed via an embedded browser that links BondEdge clients to a private web site. “The private site is an ideal way for us to make this large, complex set of data available to our clients,” explained Ms. Geske. “The browser environment and ASP technology allows us to compile and display the data in an easy-to-understand format geared to each security type.” This data is one of the most recent additions to the content of the private client site, which also offers access to CMS research publications, recent additions to the BondEdge database of fixed income securities and other information.
