Euronext outsources the information technology requirements of its business such as development, maintenance of information technology applications, and use of resources and software to Atos Euronext Market Solutions S.A.S. (AEMS), an entity 50% owned by Euronext and 50% owned by Atos Origin. The AEMS outsourcing arrangements provide Euronext with several substantial benefits in its day-to-day business, as well as generating additional revenue for Euronext. By working with Atos Origin, an information management services and information technology company, Euronext gains access to international technology skills and resources at reduced cost. The nature of the arrangements ensure that Euronext continues to receive high levels of service for its information technology needs from employees of AEMS who are already familiar with Euronexts systems. Euronext also benefits, through its equity investment in AEMS, from third-party revenues generated by AEMS, which licenses software and provides information technology services to third-party customers around the world.
AEMS grew out of Euronexts prior outsourcing 50/50 entity with Atos Origin, called AtosEuronext S.A. (AtosEuronext). The AtosEuronext entity was created in 2000 through the contribution of assets, people and technology. Euronexts contribution to AtosEuronext included the intellectual property rights for its NSC trading system, originally developed by Euronext Paris. AtosEuronext became responsible for developing, maintaining, and marketing the majority of Euronexts software products for its exchange activities.
On July 22, 2005, Euronext formed AEMS as a continuation and expansion of Atos Euronext. The main assets Euronext contributed were the activities of LIFFE Market Solutions, the information technology division of its derivatives trading business Euronext.liffe (including the proprietary LIFFE CONNECT® electronic trading system developed by LIFFE), and its 50% stake in Atos Euronext. Atos Origin contributed its own 50% share in AtosEuronext, plus other major assets from market-related businesses, including middle and back-office solutions, and its 51% stake in the connectivity platform Bourse Connect.
