HP and AtosEuronext Launch New Era of Clearinghouse Automation

Clearnet Deploys Next Generation Clearing 21® Solution on HP NonStop Servers

HP (NYSE:HPQ) and AtosEuronext today announced Clearing 21® version 3.1, a next-generation clearinghouse automation solution for financial exchanges. Clearing 21® is a post-trade management and clearing services solution that clears all products-equities, bonds, futures, and options-on a single platform, supporting both real-time and batch processing. The clearinghouse automation software runs on HP NonStop servers that deliver the highest availability and reliability in the industry, ensuring 24 x 7 operations.

Clearing 21®, an established and trusted name, has been extensively reworked and productized with a new look and feel to address the current needs in clearinghouse automation. The new version offers a full set of functions to support increasingly complex clearing and settlement operations brought on by market globalization. With Clearing 21®, stock exchanges and clearinghouses can react quickly to the growing demand for real-time clearing and settlements, offer up-to-the-second liquidity and risk management, and handle transactions that span local and global markets.

"HP and AtosEuronext are delivering the tools that drive innovation in capital markets," said Owen Kemp, vice president and general manager of HP's Global Finance Industry Business Unit. "Clearinghouses and exchanges will benefit from lower operational and system costs, guaranteed data integrity, and no single point of failure."

In fact, Clearnet, the Paris-based clearing entity for Euronext, deployed Clearing 21® on HP NonStop servers on Jan. 24, 2003 and it has been in production since then.

Said Dominique Brutin, chief executive officer of AtosEuronext: "We are pleased to bring to market Clearing 21®, which allows exchanges and clearinghouses to provide state-of-the-art clearing service. Clearing activities are going through an evolution similar to that which trading activities experienced several years ago. Globalization, operational efficiencies and compliance with regulations like T+1/0 drive the need for better and better liquidity and risk management. AtosEuronext is driving innovation in the financial clearing space as it has within the trading area, by providing real-time settlements for local, cross-boundary or global operations at the best cost. We are seeing strong demand for Clearing 21® using HP NonStop servers and are already working with major financial industry organizations toward the adoption of this innovative solution."

The integrated architecture of Clearing 21® provides secure access to trading systems and other institutions through The Hub - the AtosEuronext-supplied application-connection and message-switching application. The Hub enables clearinghouses and other member institutions to reduce technical access costs, while ensuring an open architecture for worldwide operations.

For more than a decade, AtosEuronext and HP have been delivering state-of-the-art business solutions on HP NonStop servers to the exchange and clearing house industry -- where the highest degree of innovation, reliability, and availability is required to meet the mission-critical nature of the applications that drive world markets.
