SEI to Provide Collateral Management Solution for OTC Derivatives

Company's Middle Office Services Expand to Provide Clients with an Automated and Transparent Process for Managing Counterparty Risk

DUBAI, United Arab Emirates, August 25, 2010 - SEI (Nasdaq: SEIC) announced today that it has expanded its middle office
outsourcing services to include collateral management for OTC derivatives,
providing its asset manager clients with a more automated, controlled, and
independent method by which to manage their counterparty exposure. In the
wake of market volatility, managers are looking for a more consistent and
transparent process to provide enhanced control over credit risks and
actively manage exposure levels, asset utilisation, and counterparty risk.

As part of this solution, SEI will perform the daily collateral
management functions on behalf of its clients, including managing and
electronically storing legal agreements; calculating and communicating calls,
recalls, and releases; issue resolution; and calculating and notifying
interest on collateral. Additionally, SEI has entered into a strategic
partnership with Lombard Risk, one of the world's leading providers of
collateral management, to integrate its Colline(R) system into SEI's hedge
fund platform. The system features an automated workflow that provides a
consolidated view of daily deliverables, facilitates communication, and
approvals between SEI and its clients, and improves transparency by tracking
assets during the workflow process. Clients can also access a variety of
standard and customised reports, including counterparty exposure, interest
calculations, collateral positions, and trade positions.

"By relying on SEI, investment managers are able to view and manage their
counterparty exposure online without having to invest time and resources in
building or buying their own technology solution. Investors value it because
it's managed by a trusted independent party," said Phil McCabe, Senior Vice
President and Solution Head, SEI's Investment Manager Services division.
"Investment managers continue to focus on their core competencies while at
the same time strive to improve operational efficiencies, controls and
transparency. Outsourcing middle office functions to a company such as SEI
achieves what managers are trying to accomplish."
