ADP Expands its Suite of Risk Management Tools To Include Intraday Margin System

NEW YORK, March 22, 2004 -- ADP Brokerage Services Group (ADP), a division of Automatic Data Processing, Inc. (NYSE: ADP), announced today the launch of its Intraday Margin System (IDM), a new risk management tool designed to mitigate risk and enhance productivity.

Intraday Margin System is a powerful new addition to ADP's risk management suite. The system handles margin calculations for accounts using real time account activity for trades, bookkeeping journals, dividends, checks and fund wires. Positions, balances and margin requirements are updated in real time to minimize risk and maximize potential market opportunities. Intraday Margin System enables the margin department to stay focused on customer compliance within margin regulations instead of manually calculating accounts.

In addition the system supports a What-if-Calculator that has the ability to recalculate accounts based on scenarios defined by the user. This query- defined tool performs buying power and various other margin calculations to monitor risk and exposure. IDM fully integrates with ADP's Brokerage Processing Services (BPS) back-office platform, leveraging BPS's real-time functionality and capabilities to provide a straight through processing (STP) solution for the management of market and liquidity risk, and various aspects of credit and operational risk.

Marianne Brown, senior vice president and general manager of ADP Brokerage Processing Services commented: "Keeping abreast of risk management practices, ADP continues to deliver tools that enhance business efficiency. Intraday Margin System is a valuable addition to our product offering and will provide our clients with an effective way to manage risk."
