Item 8.01 Other Events

The Company has an investment in the general partnership LSV Asset Management (LSV), a registered investment advisor that provides investment advisory services to institutions, including pension plans and investment companies. LSV is currently an investment sub-advisor for a number of SEI-sponsored mutual funds. The Company's total partnership interest in LSV was approximately 43 percent as of March 31, 2009. LSV Employee Group is owned by several current employees of LSV and was formed for the sole purpose of owning a partnership interest in LSV. The Company does not own any interest in LSV Employee Group.

In March 2009, certain partners (the Contributing partners) of LSV, including the Company, agreed to designate a portion of their partnership interest for the purpose of providing an interest in LSV to a select group of LSV key employees. Until such time an interest in the partnership is issued, all profits, losses, distributions and other rights and obligations relating to such unissued interests remains with the Contributing partners. Each issuance must be authorized by unanimous vote of all Contributing partners. As of March 31, 2009, the Contributing partners did not issue any interest in LSV.

In April 2009, the Contributing partners agreed to provide certain LSV key employees an interest in LSV, resulting in a reduction of the Company's interest in LSV to approximately 42 percent. Effective April 1, 2009, the Company will deconsolidate the assets, liabilities, revenues and expenses of LSV and account for its interest in LSV under the equity method of accounting. The Company's indirect eight percent ownership interest in LSV due to the unsecured loan guaranty provided to LSV Employee Group remained unchanged. The Company will continue to consolidate the accounts of LSV Employee Group.

As provided in General Instruction B.2 to Form 8-K, the information furnished in this Item 2.02, Item 8.01, and Exhibit 99.1 hereto shall not be deemed "filed" for purposes of Section 18 of the Securities and Exchange Act of 1934, as amended, nor shall it be deemed incorporated by reference in any filing with the Securities and Exchange Commission, except as shall be expressly provided by specific reference in such filing.
