CMS ANNOUNCES RELEASE OF PERFORMANCE ATTRIBUTION IN CANADIAN BONDEDGE SYSTEM

Los Angeles, CA, April 19, 2000 - Capital Management Sciences, a division of Data Broadcasting Corporation (Nasdaq:DBCC), announced the release of a Performance Attribution (PART) system designed for the Canadian fixed income institutional market. The new performance attribution feature is an enhancement to the Canadian version of BondEdge that was introduced in Canada in September 1999. The PART system allows a portfolio manager to determine how overall performance was affected by a general shift in the level of interest rates, a change in the slope of the yield curve, a sector allocation decision or individual bond selection.

“The investment business is competitive and since the difference between outperformance and underperformance for a fixed income portfolio is typically measured in basis points, you need a quantitative attribution analysis to see whether your investment strategy paid off,” notes Teri Geske, senior vice president of product development at CMS.

The new Canadian PART system analyzes the sources of portfolio returns compared to any one of a dozen key Canadian bond market indices from RBC Dominion Securities, including the Market Index and various government, provincial, municipal, and corporate sub-indices. The investment manager’s portfolios and RBC DS indices are analyzed using the same models to ensure consistency in identifying sources of return differences between the portfolio and the selected index. All portfolio and benchmark analyses reflect the sector breakdowns and quality ratings used in the Canadian market.

"Until now, fixed income managers have been frustrated by the lack of a comprehensive Canadian performance attribution system. The CMS PART system now allows managers to easily identify how their performance differs from the market returns. We have been very impressed with the client interest in this new feature of the CMS BondEdge system," says Charles Powis, Managing Director of North American distribution for RBC Dominion Securities.
