Further Evidence of Growing Popularity of Fiduciary Management in the UK

OAKS, Pa., March 16, 2009 – SEI (NASDAQ: SEIC), one of the largest fiduciary managers in the world, today announced that it has been appointed as fiduciary manager to the $33 million (£24 million) Habitat UK Pension and Life Assurance Plan (Habitat). As fiduciary manager, SEI will replace the pension scheme’s existing investment consultant and individual investment managers with an integrated approach combining advice and implementation.

SEI will be responsible for advising on asset and liability matching strategies, constructing an efficient investment portfolio, selecting managers to run the portfolio, and monitoring and replacing investment managers via the SEI Manager of Managers investment process. The mandate is a clear indication of the growing popularity of fiduciary management in the UK and builds on the success of SEI’s fiduciary management business, where over $6.6 billion (£4.8 billion) of new assets were secured globally in 2008.

In addition to the defined benefit pension plan, SEI is also slated to manage Habitat’s defined contribution plan, providing both advice and implementation via a range of manager-of-managers funds.

Commenting on the decision to appoint SEI, Malcolm Curzon, Chairman of Trustees of the Habitat UK Pension and Life Assurance Plan said:

“We opted for a fiduciary management approach because as a trustee body, we wanted the opportunity to be able to focus on strategic issues whilst outsourcing the day to day pensions management to an expert partner. We also felt that an approach combining advice and implementation could provide cost savings and ensure more focus on achieving our overall goals, both for the company and the pension scheme. We selected SEI because of their significant track record in fiduciary management globally and the quality of their manager-of-managers investment process.”

Commenting on the appointment, Patrick Disney, Managing Director of SEI’s Institutional Group for EMEA (Europe, Middle East and Asia) said:

“We are delighted that Habitat has taken the decision to appoint us as their fiduciary manager. This mandate demonstrates the increased interest we are starting to see in fiduciary management in the UK, as pension schemes start to see the benefits of  outsourcing strategic advice, implementation and oversight to one provider. The recent turbulence in markets, coupled with increasing complexity and regulation, has shown the flaws in the traditional pension fund management model and the need for a new approach to assist pension fund trustees in achieving good governance. We look forward to working with Habitat to achieve their goals.”

About Fiduciary Management

Fiduciary management is defined as a pension management solution which focuses on achieving the long-term goals of a pension fund within a defined risk management framework by providing both day-to-day investment management and advisory services. The approach enhances pension governance and decision-making by delegating the risk management and investment advice, implementation and oversight of the pension fund to one provider. In practice, this means that trustees can delegate the day-to-day management of the pension fund to one provider, the fiduciary manager, who is accountable to the trustees for the overall performance of the fund.

Benefits of working with a fiduciary manager who implements manager-of-managers funds:

• One point of contact rather than multiple advisers and asset managers 
• Time savings allowing increased focus by trustees on strategic issues
• Potential cost savings by working with one provider on an asset based fee
• Single focus on overall goals of the pension scheme by combining advice and implementation
• The comfort of a co-fiduciary who is accountable for manager selection decisions
• Diversification amongst managers within asset classes
• Continuous manager research, monitoring and replacement
