SEI Expands Middle-Office Services With Enhanced Pricing and Valuation Capabilities

Independent Validation Meets Demand for Increased Accuracy and Transparency

DUBAI, United Arab Emirates, January 7, 2011 - SEI (Nasdaq: SEIC) today announced that it has extended its array of
middle-office services by enhancing its asset pricing and valuation
validation solution for investment managers. The solution, which leverages
the independent valuation and pricing models of industry-leading third-party
pricing providers, is designed to provide managers with more accurate and
independent pricing verification. The solution is the latest in a series of
developments by SEI to help managers address the challenges they are facing
in valuing their investments due to rapid changes in liquidity and volatility
in global securities markets, while meeting the growing investor demands for
conflict-free transparency in a climate of increasing global regulatory and
investor scrutiny.

SEI's enhanced offering provides managers with multi-source, independent
asset pricing and valuation validation for all asset classes from more than
10 of the most respected global providers in the industry. As part of the
offering, SEI has created a seamless reporting process where pricing reports
are now made available through the company's online Manager Dashboard tool.
Among the reporting data that managers receive are valuation variance reports
detailing price comparisons, model inputs and assumptions. The multi-level,
independent process ensures greater accuracy and transparency, and also
provides managers with an additional measure of validity among, what most
experts agree, has become a more skeptical investor base, not to mention an
area of increased scrutiny by regulators.

"The increased demand for a robust and reliable valuation process, as
well as a heightened focus on valuation governance by regulators, has added
significant challenges to managers," said Jean Ebbott, Solutions Director,
SEI's Investment Manager Services division. "To effectively address these
challenges, we are providing our clients with deeper access to independent
pricing and valuation models from best-in-class partners to help them manage
risk, increase comfort among their investors, and ensure consistent and
credible pricing. Leveraging SEI's market presence, clients can gain
efficiencies from our vendor selection process and wide range of
relationships. As with all our middle-office solutions our goal is to give
managers the best tools that allow them to focus more on their portfolio
management and investors, rather than on their operations."
