Notes to Consolidated Financial Statements

(all figures are in thousands except per share data)

Note 1. Summary of Significant Accounting Policies

Nature of Operations

SEI Investments Company (the Company), a Pennsylvania corporation, provides investment processing, fund processing, and investment management business outsourcing solutions to corporations, financial institutions, financial advisors, and ultra-high-net-worth families in the United States, Canada, the United Kingdom, continental Europe, and other various locations throughout the world. Investment processing solutions utilize the Company’s proprietary software system to track investment activities in multiple types of investment accounts, including personal trust, corporate trust, institutional trust, and non-trust investment accounts, thereby allowing banks and trust companies to outsource trust and investment related activities. Revenues from investment processing solutions are recognized in Information processing and software servicing fees on the accompanying Consolidated Statements of Operations, except for fees earned associated with trade execution services.

The fund processing solution offers a full range of administration and distribution support services to mutual funds, collective trust funds, single-manager hedge funds, funds of hedge funds, private equity funds and other types of investment funds. Administrative services include fund accounting, trustee and custodial support, legal support, transfer agency and shareholder servicing. Distribution support services range from market and industry insight and analysis to identifying distribution opportunities. Revenues from fund processing solutions are recognized in Asset management, administration and distribution fees on the accompanying Consolidated Statements of Operations.

Investment management programs consist of mutual funds, alternative investments and separate accounts. These include a series of money market, equity, fixed-income and alternative investment portfolios, primarily in the form of registered investment companies. The Company serves as the administrator and investment advisor for many of these products. Revenues from investment management programs are recognized in Asset management, administration and distribution fees on the accompanying Consolidated Statements of Operations.

Basis of Presentation

The accompanying Consolidated Financial Statements have been prepared in accordance with accounting principles generally accepted in the United States of America. Certain financial information and accompanying note disclosure normally included in the Company’s Annual Report on Form 10-K has been condensed or omitted. The interim financial information is unaudited but reflects all adjustments (consisting of only normal recurring adjustments) which are, in the opinion of management, necessary for a fair statement of financial position of the Company as of June 30, 2010, the results of operations for the three and six months ended June 30, 2010 and 2009, and cash flows for the six month periods ended June 30, 2010 and 2009. These interim Consolidated Financial Statements should be read in conjunction with the audited Consolidated Financial Statements and the Notes to the Consolidated Financial Statements included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2009.

Except as disclosed herein, there have been no significant changes in significant accounting policies during the six months ended June 30, 2010 as compared to the significant accounting policies described in the Company’s Annual Report on Form 10-K for the year ended December 31, 2009.

Variable Interest Entities

The Company has involvement with various variable interest entities (VIE or VIEs). These VIEs consist of LSV Employee Group and investment products established for clients created in the form of various types of legal entity structures. In June 2009, the Financial Accounting Standards Board (FASB) issued new guidance related to the consolidation of VIEs. This guidance changed how a company determines when an entity that is insufficiently capitalized or is not controlled through voting common stock should be consolidated. The determination of whether a company is required to consolidate an entity is based on, among other things, an entity’s purpose and design, a company’s ability to direct the activities of the entity that most significantly impact the entity’s economic performance, and whether a company is obligated to absorb losses or receive benefits

Page 8 of 50

that could be potentially significant to the entity. The new guidance requires ongoing reassessments of whether an enterprise is the primary beneficiary of a VIE and requires additional disclosures about an enterprises involvement in VIEs. The new guidance became effective January 1, 2010.

Under the new guidance, LSV Employee Group remains a VIE. However, the Company is not considered the primary beneficiary because it does not have the power to direct the activities that most significantly impact the economic performance of LSV Employee Group either directly or through any financial responsibility from the Guaranty Agreement. As of January 1, 2010, the Company discontinued consolidating the accounts of LSV Employee Group. The Company does not have any direct equity interest in LSV Employee Group (See Note 2).

In January 2010, the FASB deferred the new guidance for certain types of investment entities. The deferral allows asset managers that have no obligation to fund potentially significant losses of an investment entity to continue to apply the previous guidance to investment entities that have attributes of entities defined in the “Investment Company Guide.” The deferral applies to many mutual funds, hedge funds, private equity funds, venture capital and certain other types of entities. Also, money market funds subject to rule 2a-7 of the Investment Company Act of 1940 qualify for deferral. However, the deferral does not apply to the new disclosure requirements. All of the Company’s investment products where the Company is the sponsor and/or investment manager that are VIEs qualify for the deferral; therefore, the Company will continue to apply the previous guidance for the consolidation of VIEs (See Note 3).

Cash and Cash Equivalents

Cash and cash equivalents includes $367,842 and $438,690 at June 30, 2010 and December 31, 2009, respectively, primarily invested in SEI-sponsored open-ended money market mutual funds. Cash and cash equivalents at December 31, 2009 includes $57,061 from LSV (See Note 2).

Restricted Cash

Restricted cash includes $16,000 and $17,000 at June 30, 2010 and December 31, 2009, respectively, segregated in special reserve accounts for the benefit of customers of the Company’s broker-dealer subsidiary, SEI Investments Distribution Co. (SIDCO), in accordance with certain rules established by the Securities and Exchange Commission for broker-dealers. Additionally, Restricted cash includes $3,000 at June 30, 2010 and December 31, 2009 segregated for regulatory purposes related to trade-execution services conducted by SEI Investments (Europe) Limited.

Capitalized Software

The Company capitalized $17,578 and $24,607 of software development costs during the six months ended June 30, 2010 and 2009, respectively. As of June 30, 2010, capitalized software placed into service included on the accompanying Consolidated Balance Sheet had a weighted average remaining life of approximately 11.9 years. Amortization expense related to capitalized software was $11,400 and $10,095 during the six months ended June 30, 2010 and 2009, respectively.

Software development costs capitalized during the six months ended June 30, 2010 and 2009 relates to the continued development of the Global Wealth Platform (GWP). As of June 30, 2010, the net book value of GWP was $283,113 (net of accumulated amortization of $50,783), including $13,975 of capitalized software development costs in-progress associated with future releases. GWP has an estimated useful life of 15 years and a weighted average remaining life of 12.0 years. Amortization expense for GWP was $11,117 and $9,208 during the six months ended June 30, 2010 and 2009, respectively.

Basic earnings per common share	$	53,478	189,356	$	.28


Dilutive effect of stock options		0	2,144


Diluted earnings per common share	$	53,478	191,500	$	.28


	For the Three Month Period Ended June 30, 2009

Diluted earnings per common share	$	41,571	191,933	$	.22

Employee stock options to purchase 10,422,000 and 19,522,000 shares of common stock, with an average exercise price of $24.87 and $22.35, were outstanding during the three month periods ended June 30, 2010 and 2009, respectively, but not included in the computation of diluted earnings per common share because the effect on diluted earnings per common share would have been anti-dilutive.

The calculations of basic and diluted earnings per share for the six months ended June 30, 2010 and 2009 are:


	For the Six Month Period Ended June 30, 2010
	Income (Numerator)		Shares (Denominator)	Per Share Amount

Basic earnings per common share	$	112,898	189,652	$	.60

Page 10 of 50

common share because the exercise price of the options was greater than the average market price of the Company’s common stock, and the effect on diluted earnings per common share would have been anti-dilutive.

New Accounting Pronouncements

In February 2010, the FASB issued a final Accounting Standards Update that sets forth additional requirements and guidance regarding disclosures of fair value measurements. The new standard requires the gross presentation of activity within the Level 3 fair value measurement rollforward and details of transfers in and out of Level 1 and 2 fair value measurements. It also clarifies two existing disclosure requirements on the level of disaggregation of fair value measurements and disclosures on inputs and valuation techniques. The new requirements and guidance are effective for interim and annual periods beginning in the first quarter 2010 except that the Level 3 rollforward is effective in the first quarter 2011. The adoption of the new requirements and guidance effective in the first quarter 2010 did not have a material impact on the Company’s consolidated financial statements. The Company does not expect the adoption of the guidance pertaining to the Level 3 rollforward to have a material impact on its consolidated financial statements.

Reclassifications

Certain prior year amounts have been reclassified to conform to current year presentation.

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 2006, LSV Employee Group purchased an eight percent interest in LSV from two existing partners. LSV Employee Group obtained financing in the form of a term loan pursuant to the terms of a Credit Agreement to purchase the eight percent interest in LSV. The Company agreed to provide a Guaranty Agreement to the lenders of all obligations of LSV Employee Group under the Credit Agreement. The lenders have the right to seek payment from the Company of all obligations of LSV Employee Group under the Credit Agreement in the event of default. The Company’s direct interest in LSV was unchanged as a result of this transaction.

As a result of providing the Guaranty Agreement, LSV Employee Group became a VIE and the Company was considered the primary beneficiary. Also, given the Company’s direct ownership of 43 percent in LSV at the time of this transaction in 2006 and its controlling interest in LSV Employee Group through the Guaranty Agreement, the Company was required to consolidate the assets, liabilities and operations of LSV and LSV Employee Group. The partnership interest of the other existing partners of LSV was included in Noncontrolling interest.

In January 2010, new accounting guidance pertaining to the consolidation of VIEs became effective. Under the new guidance, the Company was not considered the primary beneficiary of LSV Employee Group. The Company, therefore, discontinued consolidating the accounts and operations of LSV and LSV Employee Group in its financial statements. The Company accounts for its interest in LSV using the equity method because of its less than 50 percent ownership. The Company’s interest in the net assets of LSV is reflected in Investment in unconsolidated affiliate on the accompanying Consolidated Balance Sheet and its interest in the earnings of LSV is reflected in Equity in earnings of unconsolidated affiliate on the accompanying Consolidated Statement of Operations. The deconsolidation of LSV had no effect on Net income attributable to SEI. Prior period financial statements are not reclassified for the new accounting guidance.

LSV Asset Management

At June 30, 2010, the Company’s total investment in LSV was $61,370. The investment in LSV exceeded the underlying equity in the net assets of LSV by $4,372, of which $3,062 is considered goodwill embedded in the investment. The Company receives partnership distributions from LSV on a quarterly basis. The Company received partnership distribution payments from LSV for $44,359 and $41,195 in the six months ended June 30, 2010 and 2009, respectively. The partnership distribution payment of $21,242 received in January 2010 is reflected in LSV and LSV Employee Group cash balances, net on the accompanying Consolidated Statement of Cash Flows.

The following table contains the condensed statements of operations of LSV for the three and six months ended June 30, 2010:

LSV Employee Group

At the time of LSV Employee Group’s purchase of an eight percent interest in LSV, it was determined that $72,220 of the purchase price related to identifiable intangible assets and $19,780 was goodwill. The identifiable intangible assets have an estimated useful life of ten years and are amortized on a straight-line basis. Goodwill of $19,780 and intangible assets of $43,332 (net of accumulated amortization of $28,888) are included in the Company’s Consolidated Balance Sheet at December 31, 2009 but were the assets of LSV Employee Group. These amounts were eliminated through Noncontrolling interest. Amortization expense in the three and six months ended June 30, 2009 on the accompanying Consolidated Statement of Operations includes $1,806 and $3,611, respectively, pertaining to the amortization of the intangible assets, but was eliminated through Noncontrolling interest and had no impact on net income.

In order to finance a portion of the purchase price, LSV Employee Group obtained financing from Bank of America, N.A. and certain other lenders in the form of a term loan pursuant to the terms of a Credit Agreement. The principal amount of the term loan was $82,800, which must be paid in full by January 2011. The principal amount and interest of the term loan are paid in quarterly installments. LSV Employee Group may prepay the term loan in whole or in part at any time without penalty. As of June 30, 2010, the remaining unpaid principal balance of the term loan was $15,694. This amount is not reflected, nor is it required to be reflected, in the Company’s Consolidated Balance Sheet at June 30, 2010. LSV Employee Group made principal payments of $4,858 during the six months ended June 30, 2010. The deconsolidation of LSV Employee Group did not relinquish the Company’s obligation under the Guaranty Agreement. In the event of default by LSV Employee Group, the Company would still be obligated under the Guaranty Agreement to make any required payments to the lenders according to the term loan.

At December 31, 2009, prior to the deconsolidation of LSV Employee Group, the unpaid principal balance of the term loan was $20,552, of which $6,400 was classified as current and included in Current portion of long-term debt and the remaining $14,152 was included in Long-term debt on the accompanying Consolidated Balance Sheet.

Interest expense for the three and six months ended June 30, 2009 on the Consolidated Statement of Operations includes $377 and $793, respectively, in interest costs associated with the borrowings of LSV Employee Group which was eliminated through Noncontrolling interest and had no impact on net income.

In July 2010, LSV Employee Group made a principal payment of $2,571. As of July 31, 2010, the remaining unpaid principal balance of the term loan was $13,123. Due to the fact that LSV Employee Group has satisfied all payment requirements relating to the term loan, the Company, in its capacity as guarantor, currently has no obligation to make any payments under the Guaranty Agreement. Furthermore, the Company fully expects that LSV Employee Group will meet all of its future obligations regarding the term loan.

Note 3. Variable Interest Entities

The Company has created numerous investment products for its clients in various types of legal entity structures. The Company serves as the Manager, Administrator and Distributor for these investment products and may also serve as the Trustee for some of the investment products. Clients are the equity investors and participate equally in the net income and net capital gains of the products, and, on liquidation, will participate equally in the remaining net assets of the products after satisfaction of outstanding liabilities.

An entity that lacks decision-making rights is a VIE. In some circumstances, the Manager or Trustee of the Company’s investment products controls the governing decisions about the investment activities with respect to the ongoing operations of the investment products without the equity investors possessing the right to remove the Manager or Trustee. Therefore, the equity investors, as a group, do not have the ability to make decisions that have an impact on the ongoing activities of such investment products. Consequently, some of the Company’s investment products have been determined to be VIEs at inception.

The VIEs are marketed with investment objectives to generate positive returns; however, the nature of such investments exposes the investors to the risk that the value of the VIEs may increase or decrease. The purpose and design of the VIEs are to achieve the investment objective by implementing strategies which are designed to minimize potential losses; however, there is no assurance given that these strategies will be successful.

The Company does not have a significant equity investment in any of the VIEs and does not have an obligation to enter into any guarantee agreements with the VIEs. The fees paid to the decision maker of a VIE are considered to be variable interests if the decision maker is not subject to substantive kick-out rights. The fees paid to the Company represent a variable interest when the decision maker is not subject to substantive kick-out rights.

Page 14 of 50

The Company is not the primary beneficiary of the VIEs because the expected fees and the expected return on any investment into the VIE by the Company relative to the expected returns of the VIE to the equity investor holders does not approach 50 percent of the expected losses or gains of the VIEs. Therefore, the Company is not required to consolidate any investment products that are VIEs into its financial statements. The Company’s variable interest in the VIEs, which consists of management fees and in some situations, seed capital, would not be considered a significant variable interest.

The risks to the Company associated with its involvement with any of the investment products that are VIEs are limited to the cash flows received from the revenue generated for asset management, administration and distribution services and any equity investments in the VIEs. Both of these items are immaterial. The Company has no other financial obligation to the VIEs.

Amounts relating to fees received from the VIEs included in Receivables and amounts relating to equity investments in the VIEs included in Investments Available for Sale on the Company’s Consolidated Balance Sheets are immaterial to the total current assets of the Company.

Note 5. Fair Value Measurements

The fair value of the Company’s financial assets and liabilities are determined in accordance with the fair value hierarchy. The fair value of the Company’s financial assets, except for the fair value of structured investment vehicles (SIVs), are determined using Level 1 or Level 2 inputs and consist mainly of investments in equity and fixed-income mutual funds that are quoted daily and Government National Mortgage Association (GNMA) securities that are single issuer pools that are valued based on current market data for the specific issue owned or pools of similar GNMA securities. Level 3 financial assets consist of senior note obligations issued by SIVs. The Company did not have any Level 3 financial liabilities at June 30, 2010 or December 31, 2009. The Company provided support to two of its money market mutual funds that held SIV securities during 2009 in the form of Capital Support Agreements; however, these agreements were terminated upon the Company’s purchase of the SIV securities from the funds. The Capital Support Agreements were considered derivative securities, for which the fair value was determined using the same model to value the SIV securities. There were no transfers of financial assets between levels within the fair value hierarchy during the six months ended June 30, 2010.

The different levels of the fair value hierarchy are as follows:

Level 1 – Quoted prices in active markets for identical assets or liabilities without adjustment. The Company’s Level 1 assets primarily include investments in mutual funds sponsored by SEI and LSV that are quoted daily.

Level 2 – Observable inputs other than Level 1 prices, such as quoted prices for similar assets, quoted prices in markets that are not active, or other inputs that are observable or can be corroborated by observable market data for substantially the full term of the assets or liabilities. The Company’s Level 2 assets primarily include securities issued by GNMA with quoted prices that are traded less frequently than exchange-traded instruments. The Company uses a pricing vendor to value its GNMA securities. The pricing vendor uses a pricing model with inputs that are observable in the market or can be derived principally from or corroborated by observable market data for similar pools of GNMA securities.

Page 16 of 50

Level 3 – Unobservable inputs that are supported by little or no market activity and that are significant to the fair value of the assets or liabilities. Level 3 assets and liabilities include financial instruments whose value is determined using pricing models, or similar techniques, as well as instruments for which the determination of fair value requires significant judgment by management. The Company’s Level 3 financial assets include SIV securities and any change in fair value for these securities are recognized in the current period.

Valuation of SIV Securities

The underlying collateral of the SIV securities is mainly comprised of asset-backed securities and collateralized debt obligations. The Company received prices for all of its SIV securities from two independent third party firms. Given the lack of any reliable market data on the SIV securities, the firms utilized a valuation model that employs a net asset approach which considers the value of the underlying collateral of the SIV securities to determine the fair value of the SIV securities. Management evaluates the prices received from these firms and considers other information, such as the existence of any current market activity, to determine the fair value of the SIV securities. The underlying collateral is comprised of asset-backed securities and collateralized debt obligations that are specifically identified by its CUSIP or ISIN number.

The valuation model maintained by the first independent third party firm to value the SIV securities (except the Stanfield Victoria note) attempts to obtain price quotes from pricing vendors for each security that comprises the underlying collateral of the SIV securities. Price quotes are primarily obtained from two pricing vendors that are independent entities of the firm that maintains the valuation model. In the event a price quote is not available from the pricing vendor for a specific security, the last price quote received for that security will be adjusted by the weighted average percentage movement of securities held as collateral within the same sector classification or based upon the weighted average movement of all priced securities.

The valuation model maintained by the second independent third party firm to value the Stanfield Victoria note also attempts to value the underlying collateral of the SIV securities. However, their model does not incorporate the use of pricing vendors but instead primarily uses projected cash flows for each individual security that comprises the underlying collateral based upon proprietary models that incorporate data specific to each security and broad market data that can affect the performance of the security. Other factors may be considered that are specific to the SIV security, such as the capital structure of the SIV security, imposed restrictions, liquidity constraints and risk premiums.

The fair value of each note is sensitive mainly to changing conditions within the residential and commercial real estate markets; however, the level of sensitivity varies due to the unique characteristics of each security within the portfolio of securities that comprise each SIV security’s underlying collateral. Therefore, the risk profile for each SIV security is unique and the inputs used to determine the fair value for each SIV security is specific to each security. The Gryphon note has a large portion of its collateral in mortgage-related securities such as sub-prime 1^st and 2^nd liens, Alt A ARMs, and home equity loans. The Stanfield Victoria note primarily holds varying types of collateralized debt obligations.

Both firms that provide the fair value of the SIV securities employ a team of evaluators that review the inputs to the model and other external factors that should be considered. The models used to value all of the SIV securities are the same as those utilized to determine their fair value at December 31, 2009.

Management evaluates current market transactions, if any, for each of the SIV securities. In the event a market transaction does exist for a SIV security, management evaluates the publicly available information surrounding the transaction in order to assess if the price used represents the fair value for the SIV security. In management’s opinion, the current market for SIV securities does not represent an orderly and efficient market and has concluded that any transactions involving the SIV securities were the result of distressed sales. Therefore, market prices for any SIV securities do not represent the implied fair value of the SIV securities held by the Company.

The Company records all of its trading securities on the accompanying Consolidated Balance Sheets at fair value. Unrealized gains and losses from the change in fair value of these securities are recognized in Net gain (loss) from investments on the accompanying Consolidated Statements of Operations.

Through June 30, 2010, the Company recognized $167,820 in cumulative losses from SIV securities and SIV-related issues. During the six months ended June 30, 2010, the Company recognized gains from SIV securities of $21,262, of which $14,446 resulted from cash payments received from the SIV securities and $6,433 was from a net increase in fair value at June 30, 2010. In addition, the Company recognized a net gain or $383 from sales of two SIV securities during 2010. The cumulative loss recognized by the Company pertaining to these SIV securities was $9,571. The net gains from the SIV securities are reflected in Net gain (loss) from investments on the accompanying Consolidated Statements of Operations.

During the six months ended June 30, 2009, the Company recognized losses of $16,702 from SIV securities and SIV-related issues. During 2009, the Company purchased SIV securities from SEI-sponsored money market mutual funds. As a result of these purchases, the Company’s obligation under the Capital Support Agreements was reduced or eliminated. The losses from the purchases of the SIV securities, as well as the subsequent reduction in the Company’s required capital contribution, are reflected in Net gain (loss) from investments on the accompanying Consolidated Statements of Operations.

The Company has an investment related to the startup of mutual funds sponsored by LSV. These are U.S. dollar denominated funds that invests primarily in securities of Canadian and Australian companies as well as various other global securities. The underlying securities held by the funds are translated into U.S. dollars within the funds. During the three months ended June 30, 2010, the Company sold a portion of its investment in the LSV-sponsored funds. Additionally, the Company sold all of the equity and currency futures contracts originally purchased as part of an economic strategy to minimize exposure to price and currency risk related to the investment. The net gains recognized from the partial sale of the LSV-sponsored funds and the equity and futures contracts were minimal.

Note 7. Lines of Credit

The Company has a five-year $300,000 Credit Agreement (the Credit Facility) which expires in July 2012, at which time any aggregate principal amount of loans outstanding becomes payable in full. Any borrowings made under the Credit Facility will accrue interest at 0.500 percent above the London Interbank Offer Rate (“LIBOR”). There is also a commitment fee equal to 0.10 percent per annum on the daily unused portion of the facility. The aggregate amount of the Credit Facility may be increased by an additional $100,000 under certain conditions set forth in the agreement. The Credit Facility, as amended, contains covenants that restrict the ability of the Company to engage in mergers, consolidations, asset sales, investments, transactions with affiliates, or to incur liens, as defined in the agreement. In the event of a default under the Credit Facility, the Company would also be restricted from paying dividends on, or repurchasing, its common stock without the approval of the lenders. None of covenants of the Credit Facility negatively affect the Company’s liquidity or capital resources. Both the interest rate and commitment fee prices may increase or decrease if the Company’s leverage ratio reaches certain levels. Upon the occurrence of certain financial or economic events, significant corporate events, or certain other events of default constituting an event of default under the Credit Facility, all loans outstanding may be declared immediately due and payable and all commitments under the Credit Facility may be terminated.

The Company made principal payments of $83,000 during the six months ended June 30, 2010. As of June 30, 2010, the outstanding balance of the Credit Facility was $150,000 and is included in Long-term debt on the accompanying Consolidated Balance Sheet. The Company was in compliance with all covenants of the Credit Facility at June 30, 2010.

As of June 30, 2010, the Company’s ability to borrow from the Credit Facility is not limited by any covenant of the agreement. In management’s opinion, the leverage ratio is the most restrictive of all of the covenants contained in the Credit Facility. The leverage ratio is calculated as consolidated indebtedness divided by earnings before interest, taxes, depreciation, amortization and other items as defined by the covenant during the last four quarters (EBITDA). According to the terms of the agreement, the Company must continue to include the outstanding debt of LSV Employee Group in the calculation of consolidated indebtedness. The Company must maintain at all times a ratio of consolidated indebtedness of not more than 1.75 times the amount of EBITDA. As of June 30, 2010, the Company’s leverage ratio is 0.39 times EBITDA.

The Company considers the book value of long-term debt related to the borrowings through the Credit Facility to be representative of its fair value.

The Company’s Canadian subsidiary has a credit facility agreement (the Canadian Credit Facility) for the purpose of facilitating the settlement of mutual fund transactions. The Canadian Credit Facility has no stated expiration date. The amount of the facility is generally limited to $2,000 Canadian dollars or the equivalent amount in U.S. dollars. The Canadian Credit Facility does not contain any covenants which restrict the liquidity or capital resources of the Company. The Company had no borrowings under the Canadian Credit Facility and was in compliance with all covenants during the three months ended June 30, 2010.

Note 8. Shareholders’ Equity

Stock-Based Compensation

The Company currently has one active equity compensation plan, the 2007 Equity Compensation Plan (the 2007 Plan), which provides for the grant of incentive stock options, non-qualified stock options and stock appreciation rights with respect to up to 20 million shares of common stock of the Company, subject to adjustment for stock splits, reclassifications, mergers and other events. Permitted grantees under the 2007 Plan include employees, non-employee directors and consultants who perform services for the Company. The plan is administered by the Compensation Committee of the Board of Directors of the Company. There were no grants of incentive stock options or stock appreciation rights made under the plan in 2010 or 2009. All outstanding stock options have performance-based vesting provisions specific to each option grant that tie the vesting of the applicable stock options to the Company’s financial performance. The Company’s stock options vest at a rate of 50 percent when specified diluted earnings per share targets are achieved, and the remaining 50 percent when secondary, higher specified diluted earnings per share targets are achieved. The amount of stock-based compensation expense is based upon management’s estimate of when the earnings per share targets may be achieved.

Page 21 of 50

The Company discontinued any further grants under the Company’s 1998 Equity Compensation Plan (the 1998 Plan) as a result of the approval of the 2007 Plan. No options are available for grant from this plan. Grants made from the 1998 Plan continue in effect under the terms of the grant.

The Company recognized stock-based compensation expense in its Consolidated Financial Statements in the three month periods ended June 30, 2010 and 2009, respectively, as follows:


	Three Months Ended June 30,
	2010			2009
Stock-based compensation expense	$	6,278		$	3,361
Less: Deferred tax benefit		(2,367	)		(1,233	)

Stock-based compensation expense, net of tax	$	3,911		$	2,128


Basic and diluted earnings per share	$	.02		$	.01

The Company recognized stock-based compensation expense in its Consolidated Financial Statements in the six month periods ended June 30, 2010 and 2009, respectively, as follows:


	Six Months Ended June 30,
	2010			2009
Stock-based compensation expense	$	12,935		$	6,791
Less: Deferred tax benefit		(4,880	)		(2,058	)

Stock-based compensation expense, net of tax	$	8,055		$	4,733


Basic and diluted earnings per share	$	.04		$	.02

Management expects that certain option grants, which do not vest due to the passage of time, will not attain their higher specified diluted earnings per share targets; therefore, the Company has discontinued the amortization of the unrecognized stock-based compensation cost associated with these grants. These option grants have an unrecognized compensation cost of $21,299.

As of June 30, 2010, there was approximately $48,990 of unrecognized compensation cost remaining, adjusted for estimated forfeitures, related to unvested employee stock options. The Company estimates that compensation cost will be recognized according to the following schedule:


Period	Stock-Based Compensation Expense

Remainder of 2010	$	12,390
2011		15,022
2012		9,026
2013		7,290
2014		3,763
2015		1,499

	$	48,990

During the six months ended June 30, 2010, the Company revised its previous estimate made as of December 31, 2009 of when certain vesting targets are expected to be achieved. This change in management’s estimate resulted in a decrease of $2,492 in stock-based compensation expense in the six months ended June 30, 2010.

Page 22 of 50

During the six months ended June 30, 2009, the Company revised its estimate of when certain vesting targets are expected to be achieved. This change in management’s estimate resulted in a decrease of $3,550 in stock-based compensation expense in the six months ended June 30, 2009.

The Company issues new common shares associated with the exercise of stock options. The total intrinsic value of options exercised during the six months ended June 30, 2010 and 2009 was $4,921 and $3,007, respectively. The total options exercisable as of June 30, 2010 had an intrinsic value of $10,955. The total intrinsic value for options exercisable is calculated as the difference between the market value of the Company’s common stock as of June 30, 2010 and the exercise price of the shares. The market value of the Company’s common stock as of June 30, 2010 was $20.36 as reported by the Nasdaq Stock Market, LLC. The weighted average exercise price of the options exercisable as of June 30, 2010 was $19.35. Total options that were outstanding as of June 30, 2010 was 27,331,000.

Common Stock Buyback

The Company’s Board of Directors has authorized the repurchase of the Company’s common stock on the open market or through private transactions of up to an aggregate of $1.628 billion. Through June 30, 2010, a total of 260,420,000 shares at an aggregate cost of $1.550 billion have been purchased and retired. The Company purchased 2,421,000 shares at a total cost of $49,734 during the six months ended June 30, 2010.

The Company immediately retires its common stock when purchased. Upon retirement, the Company reduces Capital in excess of par value for the average capital per share outstanding and the remainder is charged against Retained earnings. If the Company reduces its Retained earnings to zero, any subsequent purchases of common stock will be charged entirely to Capital in excess of par value.

Cash Dividend

On May 25, 2010, the Board of Directors declared a cash dividend of $.10 per share on the Company’s common stock, which was paid on June 28, 2010, to shareholders of record on June 23, 2010. Cash dividends declared during the six month periods ended June 30, 2010 and 2009 were $18,890 and $15,301, respectively.

Investments in New Businesses – provides investment management programs to ultra-high-net-worth families residing in the United States through the SEI Wealth Network®.

In January 2010, the Company deconsolidated the assets, liabilities and operations of LSV Asset Management. As a result, LSV is no longer considered a reportable business segment in 2010.

The information in the following tables is derived from the Company’s internal financial reporting used for corporate management purposes. There are no inter-segment revenues for the three and six months ended June 30, 2010 and 2009. Management evaluates Company assets on a consolidated basis during interim periods. The accounting policies of the reportable business segments are the same as those described in Note 1 to the Consolidated Financial Statements included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2009.

Note 11. Income Taxes

The gross liability for unrecognized tax benefits at June 30, 2010 and December 31, 2009 was $5,668 and $4,989, respectively, exclusive of interest and penalties, of which $4,862 and $4,335 would affect the effective tax rate if the Company were to recognize the tax benefit.

The Company classifies interest and penalties on unrecognized tax benefits as income tax expense. As of June 30, 2010 and December 31, 2009, the combined amount of accrued interest and penalties related to tax positions taken on tax returns was $974 and $864, respectively.


	June 30, 2010		December 31, 2009
Gross liability for unrecognized tax benefits, exclusive of interest and penalties	$	5,668	$	4,989
Interest and penalties on unrecognized benefits		974		864


Total gross uncertain tax positions	$	6,642	$	5,853


Amount included in Current liabilities	$	890	$	127
Amount included in Other long-term liabilities		5,752		5,726

	$	6,642	$	5,853

The Company’s effective tax rates were 37.8 percent and 36.8 percent for the three months ended June 30, 2010 and 2009, respectively. The tax rate for the three month period in 2009 was favorably impacted by the recognition of discrete items relating to differences between estimated federal tax expense and the actual tax expense paid for 2008. For the six months ended June 30, 2010 and 2009, the Company’s tax rates were 37.8 percent and 30.3 percent, respectively. The tax rate for the six month period in 2009 was favorably impacted by the recognition of certain tax benefits as discrete items. The discrete items amounted to $7,800 and are related to the realization of prior unrecognized tax benefits that have been resolved by the conclusion of the federal and state income tax audits during the first quarter of 2009 as well the differences between the 2008 estimated federal tax expense and the actual tax expense paid.

The Company files income tax returns in the United States on a consolidated basis and in many U.S. state and foreign jurisdictions. The Company is subject to examination of income tax returns by the Internal Revenue Service (IRS) and other domestic and foreign tax authorities. An examination of the Company’s Canadian subsidiary 2005 and 2006 tax returns is currently being conducted by the Canadian tax authority. The Company is no longer subject to U.S. federal income tax examination for years before 2008 and is no longer subject to state, local or foreign income tax examinations by authorities for years before 2000.

Page 28 of 50

The Company estimates it will recognize $890 of unrecognized tax benefits within the next twelve months due to the expiration of the statute of limitations and resolution of income tax audits. These unrecognized tax benefits are related to tax positions taken on certain federal, state, and foreign tax returns. However, the timing of the resolution of income tax examinations is highly uncertain, and the amounts ultimately paid, if any, upon resolution of the issues raised by the taxing authorities may differ materially from the amounts accrued for each year. While it is reasonably possible that some issues under examination could be resolved in the next twelve months, based upon the current facts and circumstances, the Company cannot reasonably estimate the timing of such resolution or total range of potential changes as it relates to the current unrecognized tax benefits that are recorded as part of the Company’s financial statements.

Note 12. Commitments and Contingencies

In the normal course of business, the Company is party to various claims and legal proceedings. One of SEI’s principal subsidiaries, SEI Investments Distribution Co. (SIDCO), has been named as a defendant in certain putative class action complaints (the Complaints) related to leveraged exchange traded funds (ETFs) advised by ProShares Advisors, LLC, which is a client of the Company. To date, the Complaints have been filed in the United States District Court for the Southern District of New York and in the United States District Court for the District of Maryland although the three complaints filed in the District of Maryland have been voluntarily dismissed by the plaintiffs. Two of them were subsequently re-filed in the Southern District of New York. Two of the complaints filed in the Southern District of New York have been voluntarily dismissed by plaintiffs. The first complaint was filed on August 5, 2009. The Complaints are purportedly made on behalf of all persons that purchased or otherwise acquired shares in various ProShares leveraged ETFs pursuant or traceable to allegedly false and misleading registration statements, prospectuses and statements of additional information. The Complaints name as defendants ProShares Advisors, LLC; ProShares Trust; ProShares Trust II, SIDCO, and various officers and trustees to ProShares Advisors, LLC; ProShares Trust and ProShares Trust II. The Complaints allege that SIDCO was the distributor and principal underwriter for the various ProShares leveraged ETFs that were distributed to authorized participants and ultimately shareholders. The complaints allege that the registration statements for the ProShares ETFs were materially false and misleading because they failed to adequately describe the nature and risks of the investments. The Complaints allege that SIDCO is liable for these purportedly material misstatements and omissions under Section 11 of the Securities Act of 1933. The Complaints seek unspecified compensatory and other damages, reasonable costs and other relief. The cases are in the early stage, and the court has not yet appointed lead plaintiff(s). Defendants have moved to consolidate the complaints, which motion has been granted. While the outcome of this litigation is uncertain given its early phase, SEI believes that it has valid defenses to plaintiffs’ claims and intends to defend the lawsuits vigorously.

The Company has also been named in three lawsuits that were filed in August 2009 in the 19th Judicial District Court for the Parish of East Baton Rouge, State of Louisiana. One of the three actions purports to set forth claims on behalf of a class and also names SEI Private Trust Company (SPTC), one of SEI’s principal subsidiaries, as a defendant. All three actions name various defendants besides SEI, and, in all three actions, the plaintiffs purport to bring a cause of action against SEI under the Louisiana Securities Act. The putative class action also includes a claim against SEI for an alleged violation of the Louisiana Unfair Trade Practices Act. In addition, in December 2009, a group of six plaintiffs filed a lawsuit in the 23rd Judicial District Court for the Parish of Ascension, State of Louisiana against SEI and other defendants asserting claims of negligence, breach of contract, breach of fiduciary duty, violations of the uniform fiduciaries law, negligent misrepresentation, detrimental reliance, violations of the Louisiana Securities Act and Louisiana Racketeering Act and conspiracy. Further, SEI is aware that in February 2010 two groups of plaintiffs amended petitions that they had previously filed in the 19th Judicial District for the Parish of East Baton Rouge, State of Louisiana to add claims against SEI and SPTC for alleged violations of the Louisiana Securities Act, the Louisiana Racketeering Act, and civil conspiracy. The underlying allegations in all six actions are purportedly related to the role of SPTC in providing data consolidation, securities processing, and other services to Stanford Trust Company. Two of the three actions filed in East Baton Rouge have been removed to federal court, and plaintiffs’ motions to remand are pending. These two cases were also transferred

Page 29 of 50

by the Judicial Panel on Multidistrict Litigation (MDL) to a MDL pending in the Northern District of Texas. The case filed in Ascension was also removed to federal court and transferred by the Judicial Panel on Multidistrict Litigation to the same MDL pending in the Northern District of Texas. That case has been stayed. SEI and SPTC filed exceptions in the putative class action that remains pending in East Baton Rouge, which the Court granted in part and dismissed the claims under the Louisiana Unfair Trade Practices Act and denied, in part, as to the other exceptions. There is a motion for class certification that is pending in that case. The time for SEI and SPTC to respond to the two amended petitions adding claims against them has not yet run. While the outcome of this litigation is uncertain given its early phase, SEI and SPTC believe that they have valid defenses to plaintiffs’ claims and intend to defend the lawsuits vigorously.

Management’s Discussion and Analysis of Financial Condition and Results of Operations.

(In thousands, except asset balances and per share data)

This discussion reviews and analyzes the consolidated financial condition at June 30, 2010 and 2009, the consolidated results of operations for the three and six months ended June 30, 2010 and 2009 and other key factors that may affect future performance. This discussion should be read in conjunction with the Consolidated Financial Statements and the Notes to the Consolidated Financial Statements.

Overview

Consolidated Summary

We are a leading global provider of investment processing, fund processing, and investment management business outsourcing solutions that help corporations, financial institutions, financial advisors, and ultra-high-net-worth families create and manage wealth. Investment processing fees are earned as monthly fees for contracted services including computer processing services, software licenses, and trust operations services, as well as transaction-based fees for providing securities valuation and trade-execution. Fund processing and investment management fees are earned as a percentage of average assets under management or administration. As of June 30, 2010, through our subsidiaries and partnerships in which we have a significant interest, we administer $379.7 billion in mutual fund and pooled assets, manage $148.9 billion in assets, and operate from numerous countries worldwide. In January 2010, we deconsolidated the assets, liabilities and operations of LSV Asset Management. As a result, LSV is no longer considered a reportable business segment in 2010 (See “Deconsolidation of LSV and LSV Employee Group” later in this discussion).

Our Condensed Consolidated Statements of Operations for the three and six months ended June 30, 2010 and 2009 were:

In our opinion, the following items had a significant impact on our financial results for the three and six month periods ended June 30, 2010 and 2009:

•

Revenues in the three and six months ended June 30, 2010 reflect the impact of deconsolidating LSV. Excluding the revenues from LSV in 2009, our revenues increased $25.4 million, or 13 percent, in the second quarter 2010 and $38.6 million, or nine percent, in the first six months of 2010. These increases were due to improved capital markets during the later part of 2009 and during the first quarter of 2010. The severe downturn in the capital markets during the first quarter 2009 significantly affected our revenues during the prior year periods. Our assets under management, excluding LSV, increased $5.5 billion, or six percent, to $101.1 billion at June 30, 2010 from $95.5 billion at June 30, 2009. Despite the improvement in capital markets seen in late 2009 and early 2010, we expect the market decline evident in the later stages of the second quarter 2010 to negatively affect our revenues in the third quarter.

•

New business activity in our Institutional Investors and Investment Managers segments also contributed to increased revenues. New client asset funding, as well as asset funding from existing clients, for our retirement and not-for-profit solutions in our Institutional Investors segment and for our hedge fund and separately managed accounts solutions in our Investment Managers segment positively impacted revenues during the first six months of 2010.

•

Revenues in our Private Banks segment decreased in the first six months of 2010 due to lower investment processing fees from bank clients involved in mergers and acquisitions as well as lower trade-execution fees due to lower trading volumes. Furthermore, one-time revenues from fees associated with previously-announced client losses in the segment have been fully recognized; therefore, we expect third quarter revenues for this segment to reflect the full impact of the client losses.

•

New business sales events across all of our core business segments were approximately $21.6 million during the second quarter of 2010. This figure represents annualized revenues from fully implemented clients. These new sales events include newly contracted clients as well as increases in business with existing clients. We expect these new business sales to favorably impact our level of recurring revenues in future quarters.

•

We recognized $3.9 million and $21.3 million in gains from SIV securities in the three and six months ended June 30, 2010, respectively, as compared to losses of $2.3 million and $16.7 million in the prior year periods. Approximately $14.4 million of the gain in the first six months of 2010 resulted from cash payments received from the SIV securities that had been previously written down.

•

Our percentage ownership of LSV remained at approximately 42 percent. Our proportionate share in the earnings of LSV in the first six months of 2010 was $47.6 million, as compared to $31.1 million in first six months of 2009, an increase of 53 percent. LSV’s revenues significantly increased because of market appreciation in the value of assets under management. LSV’s assets under management were $47.8 billion at June 30, 2010, as compared to $40.2 billion at June 30, 2009, an increase of 19 percent.

•

We continued to invest in the Global Wealth Platform and its operational infrastructure. During the first six months of 2010, we capitalized $17.6 million for significant enhancements and new functionality for the platform, as compared to $24.6 million in the first six months of 2009. We will continue to incur significant development costs for these enhancements and upgrades. Our intention is to implement enhancements and upgrades into the platform through a series of releases.

•

Our effective tax rate for the first six months of 2010 increased to 37.8 percent as compared to 30.3 percent in the first six months of 2009. Our tax rate in 2009 was favorably impacted by the recognition of certain tax benefits related to the conclusion of federal and state income tax audits.

•

We continued our stock repurchase program during 2010 and purchased approximately 2,421,000 shares at an average price of approximately $20 per share in the six month period.

Deconsolidation of LSV and LSV Employee Group

In January 2010, new accounting guidance pertaining to the consolidation of variable interest entities (VIE or VIEs) became effective. Under the new guidance, we are not considered to be the primary beneficiary of LSV Employee

Page 32 of 50

Group and discontinued consolidating the accounts of LSV and LSV Employee Group. Our interest in LSV is accounted for using the equity method because of our less than 50 percent ownership. Our interest in the net assets of LSV is reflected in Investment in unconsolidated affiliate on the accompanying Consolidated Balance Sheet and our proportionate share in the earnings of LSV is reflected in Equity in earnings of unconsolidated affiliate on the accompanying Consolidated Statement of Operations. The deconsolidation of LSV and LSV Employee Group had no effect on Net income attributable to SEI. Prior period financial statements are not reclassified for the new accounting guidance. For more information pertaining to the deconsolidation of LSV and LSV Employee Group, see Note 2 to the Consolidated Financial Statements.

Interest and dividend income

Interest income is earned based upon the amount of cash that is invested daily and the average yield earned on those balances.

Interest expense

Interest expense in the three and six months ended June 30, 2009 includes $377 and $793, respectively, in interest charges for the borrowings of LSV Employee Group. We did not recognize any interest expense for LSV Employee Group in 2010. The remaining balance of interest expense pertains to interest charges and commitment fees associated with our credit facility.

Equity in earnings of unconsolidated affiliate

Equity in earnings of unconsolidated affiliate on the accompanying Consolidated Statement of Operations includes our less than 50 percent ownership in LSV. We deconsolidated the accounts and operations of LSV in January 2010. In 2009, LSV was a business segment and, therefore, our proportionate share in the earnings of LSV was included in the results of our business segments. Our total partnership interest in LSV remained at approximately 42 percent during the six month periods ended June 30, 2010 and 2009. Our proportionate share in the earnings of LSV was $23.5 million in the three months ended June 30, 2010 as compared to $17.4 million in three months ended June 30, 2009, an increase of 35 percent. Our proportionate share in the earnings of LSV was $47.6 million in the six months ended June 30, 2010 as compared to $31.1 million in the six months ended June 30, 2009, an increase of 53 percent. The increases in the three and six month periods in 2010 were due to increased assets under management from existing clients because of improved capital markets. LSV’s assets under management increased $7.6 billion to $47.8 billion at June 30, 2010 as compared to $40.2 billion at June 30, 2009, an increase of 19 percent. For more information pertaining to the deconsolidation of LSV and LSV Employee Group, see Note 2 to the Consolidated Financial Statements.

Page 39 of 50

Noncontrolling interest

Noncontrolling interest in 2009 primarily includes the amount owned by other shareholders or partners of LSV and LSV Employee Group.

Income Taxes

Our effective tax rates were 37.8 percent and 36.8 percent for the three months ended June 30, 2010 and 2009, respectively. For the six months ended June 30, 2010 and 2009, our effective tax rates were 37.8 percent and 30.3 percent, respectively. Our tax rate in 2009 was favorably impacted by the recognition of certain tax benefits as discrete items. The discrete items amounted to $7.8 million and are related to the realization of prior unrecognized tax benefits that have been resolved by the conclusion of the federal and state income tax audits during the first quarter of 2009 and differences between the estimated federal tax expense and the actual tax expense paid. Tax discrete items generally are not related to current year income or expense and must be entirely recognized in the quarter that they are identified.

Stock-Based Compensation

During the six months ended June 30, 2010 and 2009, we recognized approximately $12.9 million and $6.8 million, respectively, in stock-based compensation expense, an increase of $6.1 million. This increase consisted of the following components:


	Change in Stock-Based Compensation Expense
Stock-based compensation cost recognized in 2010 for grants made in December 2009	$	4,229
Change in management’s estimate of expected vesting of stock options for grants that were outstanding at December 31, 2009		2,492
Stock-based compensation cost associated with options that vested in 2009		(492	)
Other items		(85	)


	$	6,144

For more information pertaining to stock-based compensation, see Note 8 to the Consolidated Financial Statements.

Fair Value Measurements

The fair value of our financial assets and liabilities is determined in accordance with the fair value hierarchy. The fair value of most of our financial assets are determined using Level 1 or Level 2 inputs and consist mainly of investments in equity or fixed-income mutual funds that are quoted daily and Government National Mortgage Association (GNMA) securities that are single issuer pools that are valued based on current market data of similar assets. Our Level 3 financial assets consist mainly of SIV securities (See Note 5 to the Consolidated Financial Statements).

Liquidity and Capital Resources


	For the Six Months Ended June 30,
	2010			2009

Net cash provided by operating activities	$	65,689		$	133,719
Net cash used in investing activities		(42,797	)		(272,605	)
Net cash (used in) provided by financing activities		(151,840	)		215,371

Net increase (decrease) in cash and cash equivalents		(128,948	)		76,485

Cash and cash equivalents, beginning of period		590,877			416,643

Cash and cash equivalents, end of period	$	461,929		$	493,128

Cash requirements and liquidity needs are primarily funded through our cash flow from operations and our capacity for additional borrowing. At June 30, 2010, our unused sources of liquidity consisted of cash and cash equivalents and the amount available under our five-year, $300.0 million credit facility. Our credit facility is an unsecured senior revolving line of credit with JPMorgan Chase Bank, N.A., individually and as agent and a syndicate of other lenders, and is scheduled to expire in July 2012. The availability of the credit facility is subject to the compliance with certain covenants set forth in the agreement. During 2009, we borrowed $254.0 million through the credit facility and used the proceeds to purchase SIV securities from SEI-sponsored money market funds. Beginning in December 2009, we made principal payments of $104.0 million through June 2010 to reduce the outstanding balance of our credit facility. As of June 30, 2010, the outstanding balance of the credit facility was $150.0 million (See Note 7 to the Consolidated Financial Statements).

Due to the adoption of new accounting guidance, we discontinued consolidating the accounts of LSV and LSV Employee Group in January 2010 (See “Deconsolidation of LSV and LSV Employee Group” earlier in this discussion). Because of the deconsolidation, we no longer include the amount of cash and cash equivalents of LSV and LSV Employee Group on our balance sheet. The deconsolidation resulted in a net reduction of $37.1 million in our cash and cash equivalents in 2010 classified as net cash used in investing activities.

Our cash and cash equivalents include accounts managed by our subsidiaries and minority-owned subsidiaries that are used in their operations or to cover specific business and regulatory requirements. The availability of this cash for other purposes beyond the operations of these subsidiaries may be limited. As of July 31, 2010, the amount of cash and cash equivalents considered free and immediately accessible for other general corporate purposes was $368.5 million.

The decline in cash flows from operations of $68.0 million in the first six months of 2010 compared to the first six months of 2009 was primarily due to tax benefits received for net realized losses from SIV securities in 2009 which significantly reduced our tax payments in the prior year period. The net change in our working capital accounts served to partially offset this decline.

We have long-term contractual agreements with banks and other financial institutions, especially within our Private Banks segment. These banks and financial institutions continue to meet the scheduled payment terms under these contracts. We have no reason to believe that these clients will be unable to satisfy current and future obligations. Additionally, the Investment Managers segment has contractual agreements with managers of hedge funds. There have been recent concerns and issues within the hedge fund industry. We believe our clients are stable and well-respected managers that will continue to remain viable entities over the long-term. We do not have any significant collectibility issues regarding our receivables as of June 30, 2010 and we have not received any indications that we should anticipate significant collectibility issues regarding our receivables in the near term.

Net cash used in investing activities includes:

•

The deconsolidation of LSV and LSV Employee Group. The previously discussed deconsolidation of the cash accounts of LSV and LSV Employee Group resulted in a net reduction of $37.1 million in the first six months of 2010. This amount reflects the removal of the cash balances of LSV and LSV Employee Group at December 31, 2009 net of the partnership distribution payment of $21.2 million we received in the first quarter of 2010.

•

Purchases, sales and maturities of marketable securities. We had cash outflows of $24.8 million for the purchase of marketable securities in the first six months of 2010 as compared to $252.4 million in the first

Page 41 of 50

six months of 2009. Marketable securities purchased in 2010 primarily consisted of investments for the start-up of new investment products and additional GNMA securities to satisfy applicable regulatory requirements of SPTC. Marketable securities purchased in 2009 consisted of SIV securities acquired from SEI-sponsored money market funds. Sales and maturities of marketable securities, including principal prepayments received from our GNMA and SIV securities, were $51.4 million in 2010 as compared to $14.0 million in 2009.

•

The capitalization of costs incurred in developing computer software. We will continue the development of the Global Wealth Platform through a series of releases to expand the functionality and geographic reach of the platform. We capitalized $17.6 million of software development costs in the first six months of 2010 as compared to $24.6 million in the first six months of 2009. Amounts capitalized in 2010 and 2009 include costs for significant enhancements and upgrades to the platform.

•

Capital expenditures. Our capital expenditures in the first six months of 2010 primarily include equipment for our data center operations. Capital expenditures in the first six months of 2009 primarily include new computer-related equipment associated with our investment processing platforms.

Net cash used in financing activities includes:

•

Principal payments of our debt. We made principal payments of $83.0 million in the first six months of 2010 to reduce the outstanding debt associated with our credit facility. Principal payments in the first six months of 2009 consist of payments made by LSV Employee Group for amounts previously included in our debt. Due to the deconsolidation of LSV Employee Group in January 2010, we no longer include the principal payments of LSV Employee Group in cash flows from financing activities.

•

Borrowings on long-term debt. In the first six months of 2009, we borrowed $254.0 million through our credit facility to finance our purchases of SIV securities from SEI-sponsored money market funds. There were no borrowings related to our credit facility in the first six months of 2010.

•

Dividend payments. Cash dividends paid were $36.0 million or $.19 per share in the first six months of 2010 and $30.6 million or $.16 per share in the first six months of 2009.

•

The repurchase of our common stock. Our Board of Directors has authorized the repurchase of up to $1.628 billion worth of our common stock. Through July 31, 2010, we repurchased approximately 260.8 million shares of our common stock at a cost of $1.557 billion and had $71.8 million of authorization remaining for the purchase of our common stock under this program. We spent approximately $49.7 million during the first six months of 2010 and $13.6 million during the first six months of 2009 for the repurchase of our common stock. Currently, there is no expiration date for our common stock repurchase program.

We believe our operating cash flow, available borrowing capacity, and existing cash and cash equivalents should provide adequate funds for ongoing operations; continued investment in new products and equipment; our common stock repurchase program; principal payments on our debt; and future dividend payments.

Forward-Looking Information and Risk Factors

The Private Securities Litigation Reform Act of 1995 provides a “safe harbor” for forward-looking statements. Certain information contained in this discussion is or may be considered forward-looking. Forward-looking statements relate to future operations, strategies, financial results or other developments. Forward-looking statements are based upon estimates and assumptions that involve certain risks and uncertainties, many of which are beyond our control or are subject to change. Although we believe our assumptions are reasonable, they could be inaccurate. Our actual future revenues and income could differ materially from our expected results. We have no obligation to publicly update or revise any forward-looking statements.

Among the risks and uncertainties which may affect our future operations, strategies, financial results or other developments are those risks described in our latest Annual Report on Form 10-K in Part I, Item 1A. These risks include the following:

•

changes in capital markets that may affect our revenues and earnings;

•

product development risk;

•

consolidation within our target markets, including consolidations between banks and other financial institutions;

•

risk of failure by a third-party service provider;

•

the performance of the funds we manage;

•

the affect of extensive governmental regulation; including changes in laws or regulations and changes in the identity or policies of the regulators having jurisdiction over our regulated subsidiaries, products or clients;

•

systems and technology risks;

•

data security risks;

•

third party approval of our investment products with advisors affiliated with independent broker-dealers or other networks;

•

operational risks associated with the processing of investment transactions, including, but not limited to, improper operation of systems, human error or improper action by employees;

•

changes in, or interpretation of, accounting principles or tax rules and regulations;

•

fluctuations in foreign currency exchange rates; and

•

retention of senior management personnel.

The Company and our clients are subject to extensive governmental regulation. Our various business activities are conducted through entities which may be registered with the Securities and Exchange Commission (SEC) as an investment advisor, a broker-dealer, a transfer agent, an investment company or with the United States Office of Thrift Supervision or state banking authorities as a trust company. Our broker-dealer is also a member of the Financial Industry Regulatory Authority and is subject to its rules and oversight. In addition, various subsidiaries of the Company are registered with, and subject to the oversight of, regulatory authorities primarily in the United Kingdom and the Republic of Ireland. Many of our clients are subject to substantial regulation by federal and state banking, securities or insurance authorities or the Department of Labor. Compliance with existing and future regulations and responding to and complying with recent regulatory activity affecting broker-dealers, investment companies and their service providers could have a significant impact on us. We periodically undergo regulatory examinations and respond to regulatory inquiries and document requests. As a result of these examinations, inquiries and requests, we review our compliance procedures and business operations, and make changes as we deem necessary, some of which may result in increased expense or may reduce revenues. We offer investment and banking products that also are subject to regulation by the federal and state securities and banking authorities, as well as non-United States regulatory authorities, where applicable. Existing or future regulations that affect these products could lead to a reduction in sales of these products.

The Dodd-Frank Wall Street Reform and Consumer Protection Act signed into law on July 21, 2010 makes extensive changes to the laws regulating financial services firms. Among other things, this Act abolishes the Office of Thrift Supervision and transfers its functions to the other federal banking agencies. The legislation requires significant rule-making and mandates multiple studies, which could result in additional legislative or regulatory action. The Company is currently evaluating the impact the legislation will have on us and our subsidiaries and the products and services we provide to our clients.

Our bank clients are subject to supervision by federal and state banking authorities concerning the manner in which such clients purchase and receive our products and services. Our plan sponsor clients and our subsidiaries

Page 43 of 50

providing services to those clients are subject to supervision by the Department of Labor and compliance with employee benefit regulations. Investment advisor and broker-dealer clients are regulated by the SEC and state securities authorities. Existing or future regulations applicable to our clients may affect our clients’ purchase of our products and services.

In addition, see the discussion of governmental regulations in Item 1A “Risk Factors” in our latest Annual Report on Form 10-K for a description of the risks that proposed regulatory changes may present for our business.

Item 3.

Quantitative and Qualitative Disclosures About Market Risk.

Information regarding our market risk exposures appears in Part II - Item 7A of our Annual Report on Form 10-K for the year ended December 31, 2009. There have been no material changes in our market risk exposures from those disclosed in our Annual Report on Form 10-K for 2009.

Item 4.

Controls and Procedures.

(a) Evaluation of Disclosure Controls and Procedures

Our management, with the participation of our Chief Executive Officer and Chief Financial Officer, evaluated the effectiveness of our disclosure controls and procedures as of the end of the period covered by this report. Based on that evaluation, the Chief Executive Officer and Chief Financial Officer concluded that our disclosure controls and procedures as of the end of the period covered by this report are effective in ensuring that information required to be disclosed by us in reports filed under the Securities Exchange Act of 1934 (the Exchange Act) is recorded, processed, summarized and reported within the time periods specified in the SEC’s rules and forms. Disclosure controls and procedures include, without limitation, controls and procedures designed to ensure that information required to be disclosed by an issuer in the reports that it files or submits under the Exchange Act is accumulated and communicated to the issuer’s management including its principal executive and principal financial officers, or persons performing similar functions, as appropriate to allow timely decisions regarding required disclosure. A controls system, no matter how well designed and operated, cannot provide absolute assurance that the objectives of the controls systems are met, and no evaluation of controls can provide absolute assurance that all control issues and instances of fraud, if any, within a company have been detected.

(b) Change in Internal Control over Financial Reporting

No change in our internal control over financial reporting occurred during the quarter ended June 30, 2010 that has materially affected, or is reasonably likely to materially affect, our internal control over financial reporting.

PART II. OTHER INFORMATION

Item 1.

Legal Proceedings.

One of SEI’s principal subsidiaries, SEI Investments Distribution Co. (SIDCO), has been named as a defendant in certain putative class action complaints (the Complaints) related to leveraged exchange traded funds (ETFs) advised by ProShares Advisors, LLC. To date, the Complaints have been filed in the United States District Court for the Southern District of New York and in the United States District Court for the District of Maryland although the three complaints filed in the District of Maryland have been voluntarily dismissed by the plaintiffs. Two of them were subsequently re-filed in the Southern District of New York. Two of the complaints filed in the Southern District of New York have been voluntarily dismissed by plaintiffs. The first complaint was filed on August 5, 2009. The Complaints are purportedly made on behalf of all persons that purchased or otherwise acquired shares in various ProShares leveraged ETFs pursuant or traceable to allegedly false and misleading registration statements, prospectuses and statements of additional information. The Complaints name as defendants ProShares Advisors, LLC; ProShares Trust; ProShares Trust II, SIDCO, and various officers and trustees to ProShares Advisors, LLC; ProShares Trust and ProShares Trust II. The Complaints allege that SIDCO was the distributor and principal underwriter for the various ProShares leveraged ETFs that were distributed to authorized participants and ultimately shareholders. The complaints allege that the registration statements for the ProShares ETFs were materially false and misleading because they failed adequately to describe the nature and risks of the investments. The Complaints allege that SIDCO is liable for these purportedly material misstatements and omissions under Section 11 of the Securities Act of 1933. The Complaints seek unspecified compensatory and other damages, reasonable costs and other relief. The cases are in the early stage, and the court has not yet appointed lead plaintiff(s). Defendants have moved to consolidate the complaints, which motion has been granted. While the outcome of this litigation is uncertain given its early phase, SEI believes that it has valid defenses to plaintiffs’ claims and intends to defend the lawsuits vigorously.

SEI has also been named in three lawsuits that were filed in August 2009 in the 19th Judicial District Court for the Parish of East Baton Rouge, State of Louisiana. One of the three actions purports to set forth claims on behalf of a class and also names SEI Private Trust Company (SPTC) as a defendant. All three actions name various defendants besides SEI, and, in all three actions, the plaintiffs purport to bring a cause of action against SEI under the Louisiana Securities Act. The putative class action also includes a claim against SEI for an alleged violation of the Louisiana Unfair Trade Practices Act. In addition, in December 2009, a group of six plaintiffs filed a lawsuit in the 23rd Judicial District Court for the Parish of Ascension, State of Louisiana, against SEI and other defendants asserting claims of negligence, breach of contract, breach of fiduciary duty, violations of the uniform fiduciaries law, negligent misrepresentation, detrimental reliance, violations of the Louisiana Securities Act, and Louisiana Racketeering Act and conspiracy. Further, SEI is aware that, in February 2010, two groups of plaintiffs amended petitions they had previously filed in the 19th Judicial District for the Parish of East Baton Rouge, State of Louisiana, to add claims against SEI and SPTC for alleged violations of the Louisiana Securities Act, the Louisiana Racketeering Act, and civil conspiracy. The underlying allegations in all six actions are purportedly related to the role of SPTC in providing data consolidation, securities processing, and other services to Stanford Trust Company. Two of the three actions filed in East Baton Rouge have been removed to federal court, and plaintiffs’ motions to remand are pending. These two cases were also transferred by the Judicial Panel on Multidistrict Litigation (MDL) to a MDL pending in the Northern District of Texas. The case filed in Ascension was also removed to federal court and transferred by the Judicial Panel on Multidistrict Litigation to the same MDL pending in the Northern District of Texas. That case has been stayed. SEI and SPTC filed exceptions in the putative class action that remains pending in East Baton Rouge, which the Court granted in part and dismissed the claims under the Louisiana Unfair Trade Practices Act and denied, in part, as to the other exceptions. There is a motion for class certification that is pending in that case. The time for SEI and SPTC to respond to the two amended petitions adding claims against them has not yet run. While the outcome of this litigation is uncertain given its early phase, SEI and SPTC believe that they have valid defenses to plaintiffs’ claims and intend to defend the lawsuits vigorously.
