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 affluent 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, hedge funds, fund of 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 Company-sponsored 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.

Effective January 1, 2007, the Company changed the names of three of its business segments. The Private Banking and Trust business segment was renamed as Private Banks, the Enterprises business segment was renamed as Institutional Investors, and the Money Managers business segment was renamed as Investment Managers. Additionally, the structure of two of the Company’s business segments changed on January 1, 2007. The investment management programs and services offered to global private banks of the Investments in New Businesses segment was moved to the Private Banks segment. Further information pertaining to the Company’s new business segments is included in Note 10.

Basis of Presentation

The accompanying Consolidated Financial Statements have been prepared in accordance with accounting principles generally accepted in the United States of America, consistent in all material respects with those applied in the Company’s Annual Report on Form 10-K for the year ended December 31, 2006. 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 to present fairly the financial position of the Company as of June 30, 2007, the results of operations for the three and six months ended June 30, 2007 and 2006, and cash flows for the six month periods ended June 30, 2007 and 2006. 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, 2006.

Except as disclosed herein, there have been no significant changes in significant accounting policies during the six months ended June 30, 2007 as compared to the significant accounting policies described in the Company’s Annual Report on Form 10-K for the year ended December 31, 2006.

Page 6 of 39

Cash and Cash Equivalents

Cash and cash equivalents includes $58,404 and $110,663 at June 30, 2007 and December 31, 2006, respectively, primarily invested in Company-sponsored open-ended money market mutual funds.

Restricted Cash

Restricted cash at June 30, 2007 and December 31, 2006 includes $10,000 segregated in special reserve accounts for the benefit of SIDCO customers in accordance with certain rules established by the Securities and Exchange Commission for broker-dealers and $250 segregated for regulatory purposes related to trade-execution services conducted by our subsidiary located in the United Kingdom.

Capitalized Software

The Company capitalized $35,662 and $36,835 of software development costs during the six months ended June 30, 2007 and 2006, respectively. As of June 30, 2007, capitalized software placed into service included on the accompanying Consolidated Balance Sheet had a weighted average remaining life of approximately 7.2 years. Amortization expense related to capitalized software was $1,522 and $2,418 during the six months ended June 30, 2007 and 2006, respectively.

In July 2007, the Global Wealth Platform was placed into service. The amount of capitalized software development costs related to the platform was $199,552. These costs will begin to be amortized during the third quarter of 2007 using the straight-line method over an estimated useful life of 15 years.

In the six month period ended June 30, 2006, the Company determined that the front-end component of the SEI Advisor Desktop did not fully satisfy the expected functionality requirements and would require additional investment. Management decided to discontinue any further development work for this front-end component and wrote-off $3,429 of previously capitalized software development costs. Additionally, $2,265 of previously capitalized software development costs related to other discontinued projects associated with the Global Wealth Platform were written-off in the first half of 2006. The charges for capitalized software development costs written-off are included in Facilities, supplies and other costs on the accompanying Consolidated Statements of Operations. There were no capitalized software development costs written-off in the six month period ended June 30, 2007.

Income Taxes

The Company applies the asset and liability approach to account for income taxes pursuant to Statement of Financial Accounting Standards No. 109 (SFAS 109), “Accounting for Income Taxes.” Under SFAS 109, deferred tax assets and liabilities are recognized for the future tax consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases. Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled. The components of the deferred tax assets and liabilities are individually classified as current and non-current based on their characteristics.

The Company adopted the FASB Interpretation No. 48, “Accounting for Uncertainty in Income Taxes - an interpretation of FASB Statement No. 109” (FIN 48), effective January 1, 2007. FIN 48 clarifies the accounting for uncertainty in income taxes recognized in financial statements and requires the impact of a tax position to be recognized in the financial statements if that position is more likely than not of being sustained by the taxing authority. The adoption of FIN 48 did not have a material impact on the Company’s financial position or results of operations (See Note 11).

Fair Value of Financial Instruments

The book value of current assets and current liabilities is considered to be representative of their fair value because of their short maturities. Held-to-maturity securities are stated at amortized cost, which approximates fair value. The book value of long-term debt is considered to be representative

Page 7 of 39

of its fair value based upon an estimation using borrowing rates currently available to the Company for bank loans with similar terms and maturities. The recorded value of these items approximates their fair value at June 30, 2007.

The calculations of basic and diluted earnings per share for the three months ended June 30, 2007 and 2006 are:


	For the Three Month Period Ended June 30, 2007
	Income (Numerator)		Shares (Denominator)	Per Share Amount
Basic earnings per common share	$	69,501	197,314	$	.35

Diluted earnings per common share	$	57,911	202,526	$	.29

Employee stock options to purchase 3,513,000 and 2,014,000 shares of common stock, with an average exercise price of $29.64 and $24.98, were outstanding during the three month periods ended June 30, 2007 and 2006, 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, 2007 and 2006 are:


	For the Six Month Period Ended June 30, 2007
	Income (Numerator)		Shares (Denominator)	Per Share Amount
Basic earnings per common share	$	132,878	197,614	$	.67

Dilutive effect of stock options		—	6,539

Diluted earnings per common share	$	132,878	204,153	$	.65


	For the Six Month Period Ended June 30, 2006
	Income (Numerator)		Shares (Denominator)	Per Share Amount
Basic earnings per common share	$	112,817	197,254	$	.57

Dilutive effect of stock options		—	5,320

Diluted earnings per common share	$	112,817	202,574	$	.56

Employee stock options to purchase 3,563,000 and 8,518,000 shares of common stock, with an average exercise price of $29.58 and $22.33, were outstanding during the six month periods ended June 30, 2007 and 2006, respectively, but not included in the computation of diluted earnings per 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 September 2006, the FASB issued FASB Statement No. 157 (SFAS 157), “Fair Value Measurements.” SFAS 157 establishes a framework for measuring fair value in generally accepted accounting principles and expands disclosures about fair value measurements. SFAS 157 is effective for all financial statements issued for fiscal years beginning after November 15, 2007. The Company does not expect the adoption of SFAS 157 to have a material impact on its financial statements.

In February 2007, the FASB issued FASB Statement No. 159 (SFAS 159), “The Fair Value Option for Financial Assets and Financial Liabilities.” SFAS 159 permits companies to choose to measure certain financial instruments and certain other items at fair value. The standard requires that unrealized gains and losses on items for which the fair value option has been elected be reported in earnings. SFAS 159 is effective for all financial statements issued for fiscal years beginning after November 15, 2007. The Company is currently evaluating the impact that SFAS 159 will have on its financial statements.

Reclassifications

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

Note 2.

LSV and LSV Employee Group

The Company has an investment in the general partnership LSV, a registered investment advisor that provides investment advisory services to institutions, including pension plans and investment companies. LSV is currently an investment sub-adviser for a number of Company-sponsored mutual funds. The Company’s total partnership interest in LSV was approximately 43 percent during 2006 and 2007. LSV Employee Group is owned by several current employees of LSV and was formed in January 2006 for the sole purpose of owning a partnership interest in LSV. The Company does not own any interest in LSV Employee Group.

In January 2006, two partners of LSV, excluding the Company, sold in the aggregate an eight percent interest in LSV to LSV Employee Group. The Company entered into a Guaranty Agreement with LSV Employee Group, LaSalle Bank National Association as administrative agent (the Agent), and certain other lenders in order to facilitate the acquisition of certain partnership interests of LSV by LSV Employee Group. LSV Employee Group obtained financing from the Agent and certain other lenders in the form of a term loan pursuant to the terms of a Credit Agreement (See LSV Employee Group Term Loan below).

Pursuant to the terms and conditions of the Guaranty Agreement, the Company has agreed to provide an unsecured guaranty to the lenders of all obligations of LSV Employee Group under the Credit Agreement. In the event of default by LSV Employee Group, the lenders have the right to seek payment from the Company of all obligations of LSV Employee Group under the Credit Agreement. As recourse for such payment, the Company will be subrogated to the rights of the lenders under the Credit Agreement and the Guaranty Agreement, including the security interest in the pledged interests transferred to LSV Employee Group.

LSV Employee Group meets the definition of a variable interest entity and the Company is the primary beneficiary. As a result of this transaction, the Company has a controlling financial interest in LSV through its direct ownership of LSV and guaranty of LSV Employee Group’s debt. The Company therefore consolidated the assets, liabilities and operations of LSV and LSV Employee Group in its Consolidated Financial Statements beginning in January 2006. The Company’s percentage of direct ownership in LSV was unchanged (approximately 43 percent) as a result of this transaction. The amount of ownership of the other existing partners (approximately 57 percent) of LSV is included in Minority interest.

In accordance with the terms of the Assignment and Purchase Agreement (the Purchase Agreement), LSV Employee Group only receives their percentage interest in the future earnings of LSV from the date of the Purchase Agreement and did not acquire any right to any of the sellers’

remaining undistributed earnings of LSV. Initially, the Company determined that the entire purchase price of $92,000 was goodwill. In late 2006, the Company revised its determination and allocated a portion of the total purchase price to identifiable intangible assets that require recognition apart from goodwill. The Company determined that $72,220 related to those identifiable intangible assets and the remaining $19,780 was goodwill. The identifiable intangible assets have an estimated life of ten years and are amortized on a straight-line basis. The Company recognized $3,611 in amortization expense during the six months ended June 30, 2007 and 2006 which is reflected in Depreciation and amortization expense on the accompanying Consolidated Statement of Operations. The amount of amortization expense in 2006 was revised for the identification of intangible assets. Amortization expense recognized in the Consolidated Statement of Operations associated with the assets of LSV Employee Group was eliminated through Minority interest and had no impact on net income.

LSV Employee Group Term Loan

In order to finance a portion of the purchase price, LSV Employee Group obtained financing from LaSalle Bank National Association 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 is $82,800. The principal amount and interest of the term loan are paid in quarterly installments. The total outstanding principal balance of the term loan must be paid in full by January 2011. LSV Employee Group may prepay the term loan in whole or in part at any time without penalty. As of June 30, 2007, the remaining unpaid principal balance of the term loan was $62,622, of which $8,800 is classified as current and included in Current portion of long-term debt and the remaining $53,822 is included in Long-term debt on the accompanying Consolidated Balance Sheets. LSV Employee Group made principal payments of $9,016 and $3,761 during the six months ended June 30, 2007 and 2006, respectively. Interest expense for the six months ended June 30, 2007 and 2006 on the Consolidated Statements of Operations includes $2,039 and $2,058, respectively, associated with the borrowings of LSV Employee Group which was eliminated through Minority interest and had no impact on net income.

LSV Employee Group made a principal payment of $4,679 in July 2007. The remaining unpaid principal balance of the term loan at July 31, 2007 was $57,943. The Company, in its capacity as guarantor, currently has no obligation of payment relating to the term loan of LSV Employee Group.

Note 3.

Goodwill and Other Intangible Asset

In June 2003, the Company purchased an additional percentage ownership in LSV. The total purchase price was allocated to LSV’s net tangible and intangible assets based upon their estimated fair values at the date of purchase. The excess purchase price over the value of the net tangible and identifiable intangible assets was recorded as goodwill. The total amount of goodwill from this transaction amounted to $3,062 and is included on the accompanying Consolidated Balance Sheets.

The Company identified an intangible asset related to customer contracts that met the contractual-legal criterion for recognition apart from goodwill. The fair value of the intangible asset was determined to be $3,821 with a definite life of eight and a half years. The identified intangible asset is amortized on a straight-line basis. The Company recognized $218 of amortization expense during the six months ended June 30, 2007 and 2006, which is reflected in Depreciation and amortization expense on the accompanying Consolidated Statements of Operations.

Note 8.

Shareholders’ Equity

Stock-Based Compensation

On April 3, 2007, the Company’s Board of Directors approved the 2007 Equity Compensation Plan (the 2007 Plan), which was later approved by the shareholders of the Company on May 23, 2007. The 2007 Plan became effective June 1, 2007 and 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 stock options or stock appreciation rights made under the 2007 Plan as of June 30, 2007.

Effective June 1, 2007, 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. The Company also maintains three additional equity compensation plans which have non-qualified stock options outstanding, but these plans have been terminated. No options are available for grant from these terminated plans, and grants made under these plans continue in effect under the terms of the grant and the applicable plan. All of the Company’s equity compensation plans are administered by the Company’s Compensation Committee.

All outstanding stock options have performance vesting conditions based on the attainment of certain earnings per share targets established at the date of grant. Earnings per share targets are calculated exclusive of stock-based compensation expense, net of tax. The first performance condition determines vesting of 50 percent of the options, and a second performance condition determines the vesting of the remaining 50 percent of the options. The performance conditions are measured annually on December 31. Options granted prior to 2006 also could vest in their entirety seven years from the date of grant. The Company believes that awarding stock options with performance-based vesting schedules better aligns the interests of stockholders and employees.

The Company recognized stock-based compensation expense in its Consolidated Financial Statements in the three month periods ended June 30, 2007 and 2006, respectively, as follows:


	Three Months Ended June 30,
	2007			2006
Stock-based compensation expense	$	6,941		$	3,595
Less: Deferred tax benefit		(1,717	)		(1,167	)

Stock-based compensation expense, net of tax	$	5,224		$	2,428

Basic and diluted earnings per share	$	.03		$	.01

Page 18 of 39

The Company recognized stock-based compensation expense in its Consolidated Financial Statements in the six month periods ended June 30, 2007 and 2006, respectively, as follows:


	Six Months Ended June 30,
	2007			2006
Stock-based compensation expense	$	13,458		$	8,082
Less: Deferred tax benefit		(4,041	)		(2,949	)

Stock-based compensation expense, net of tax	$	9,417		$	5,133

Basic and diluted earnings per share	$	.05		$	.03

As of June 30, 2007, there was approximately $48,634 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 2007	$	13,628
2008		14,273
2009		7,229
2010		3,857
2011		3,857
2012		3,815
2013		1,975

	$	48,634

During the three month period ended June 30, 2007, the Company accelerated the recognition of $580 in stock-based compensation expense due to a change in management’s estimate of when certain vesting targets are expected to be achieved.

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, 2007 was $40,158. The total options outstanding as of June 30, 2007 was 26,725,000.

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 $1,328,365, including an additional authorization on July 24, 2007 for $75,000. Through June 30, 2007, a total of 246,032,000 shares at an aggregate cost of $1,235,804 have been purchased and retired. The Company purchased 4,170,000 shares at a total cost of $124,694 during the six months ended

June 30, 2007.

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.

Stock Split

On May 23, 2007, the Board of Directors approved a two-for-one stock split of the Company’s $.01 par value common stock, effected in the form of a stock dividend which was paid on June 21, 2007 to shareholders of record on June 11, 2007. The par value of the stock remained unchanged. Accordingly, a total of $981 was reclassified from Retained earnings to Common stock. All per-share amounts have been adjusted to reflect the stock split. Amounts of Common stock at December 31, 2006 on the accompanying Consolidated Balance Sheets have not been retroactively adjusted.

Page 19 of 39

Cash Dividend

Commitments and Contingencies

Legal Proceedings

In the normal course of business, the Company is party to various claims and legal proceedings. On September 30, 2004, SIDCO was named as a defendant in a putative consolidated amended class action complaint filed in the United States District Court for the District of Maryland titled “Stephen Carey v. Pilgrim Baxter & Associates, LTD, et. al.” This complaint was purportedly made on behalf of all persons that purchased or held PBHG mutual funds during the period from November 1, 1998 to November 13, 2003 and related generally to various market timing practices allegedly permitted by the PBHG Funds. The complaint alleged that SIDCO was the named distributor/underwriter from November 1998 until July 2001 for various PBHG funds in which market timing allegedly occurred during that period. In 2006, the plaintiffs submitted a proposed form of order dismissing SIDCO from the action, but the Court has not yet acted on the proposed order. The Company had not made any provision relating to this legal proceeding.

Note 11.

Income Taxes

Effective January 1, 2007, the Company adopted the provisions of FIN 48, which did not have a material impact on its financial statements. The Company’s total unrecognized tax benefit as of January 1, 2007 and June 30, 2007 was $11,275 and $12,862, respectively, of which approximately $10,980 and $12,177 would affect the effective tax rate if the Company were to recognize the tax benefit. During the six months ended June 30, 2007, the Company has not recognized any material increase or decrease in tax liability for unrecognized tax benefits as a result of the implementation of FIN 48.

The Company files a consolidated federal income tax return and income tax returns with various states. Certain subsidiaries of the Company file tax returns in foreign jurisdictions. The Company’s federal income tax return is not currently under examination; however, certain prior year tax returns of the Company’s domestic and foreign subsidiaries are under examination by state and foreign tax authorities. The Company is no longer subject to U.S. federal income tax examination for years before 2003 and is no longer subject to state, local or foreign income tax examinations by tax authorities for years before 2000.

The portion of unrecognized tax benefit that is anticipated to be paid within 12 months is included in current taxes payable and the remaining amount of $11,619 is included in Other long-term liabilities as of June 30, 2007 on the accompanying Consolidated Balance Sheets. The amount of unrecognized tax benefit that relates to items in which the related statute of limitation is scheduled to expire within 12 months is $809. However, it is not reasonably possible to estimate the total amount of increase or decrease in these unrecognized tax benefits which may occur in the next 12 months due to the uncertainty of the outcome of examinations from taxing authorities, changes in the interpretation of tax laws resulting from undecided court cases and other factors.

The Company classifies interest and penalties recognized associated with uncertain tax positions as a component of income tax expense. As of January 1, 2007 and June 30, 2007, the Company had accrued approximately $1,817 and $1,813 of interest and penalties associated with our uncertain tax positions.

Overview

Our Business and Business Segments

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 affluent 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, 2007, through our subsidiaries and partnerships in which we have a significant interest, we administer $406.7 billion in mutual fund and pooled assets, manage $198.7 billion in assets, and operate from more than 20 offices in over a dozen countries.

In January 2007, we changed the names of three of our business segments. The Private Banking & Trust business segment was renamed as Private Banks, the Enterprises business segment was renamed as Institutional Investors, and the Money Managers business segment was renamed as Investment Managers. Additionally, we reorganized the structure of two of our business segments. The investment management programs and services offered to global private banks of the Investments in New Businesses segment was moved to the Private Banks segment. For comparability, the prior period’s results have been reclassified to reflect the realignment of these two business segments.

The Company’s reportable business segments are:

Private Banks - provides investment processing and investment management programs to banks and trust institutions worldwide;

Institutional Investors - provides investment management programs and administrative outsourcing solutions to retirement plan sponsors and not-for-profit organizations worldwide;

Investments in New Businesses - provides investment management programs to affluent families residing in the United States and Europe through the SEI Wealth Network^®; and

LSV Asset Management - is a registered investment advisor that provides investment advisory services to institutions, including pension plans and investment companies.

Consolidated Summary

Consolidated revenues increased $58.2 million, or 20 percent, to $343.3 million for the three months ended June 30, 2007 compared to the three months ended June 30, 2006. For the six month period ended, revenues increased $103.8 million, or 18 percent, to $666.0 million compared to the prior year period. Net income increased $11.6 million, or 20 percent, to $69.5 million for the three month period and $20.1 million, or 18 percent, to $132.9 million for the six month period. Diluted earnings per share for the three month period were $.34 per share as compared to $.29 per share a year ago, an increase of 17 percent. In the six month period, diluted earnings per share increased to $.65 per share as compared to $.56 per share a year ago, an increase of 16 percent.

In our opinion, the following items had a significant impact on our financial results for the three and six month periods ended June 30, 2007 and 2006:

•

Revenue growth across all of our segments was primarily driven by higher asset-based fees from capital market appreciation. Favorable capital market conditions increased the value of assets we manage or administer for our existing clients, resulting in an increase in our base revenues. These market conditions also generated improved profits and operating margins in our Investment Advisors, Institutional Investors, Investment Managers and LSV business segments.

•

Sales of new business in our Institutional Investors and Investment Managers business segments as well as positive cash receipts in late 2006 and 2007 from new and existing advisor relationships in our Investment Advisors business segment also contributed to the increase in our revenues and profits.

•

We capitalized $35.7 million in software development costs for the Global Wealth Platform in the six months ended June 30, 2007 compared to $36.8 million in the comparable period of 2006. The Global Wealth Platform was placed into service in July 2007. Capitalized software development costs of $199.6 million will be amortized over 15 years beginning in the third quarter of 2007. We will continue to incur significant development costs as enhancements and upgrades to expand the functionality of the Global Wealth Platform are developed and implemented. We expect to incur costs related to maintenance and training, which will be expensed as incurred, as we enter the operational stage in the development of the platform.

•

Consolidated operating margins were negatively affected by increased spending for the development of the necessary infrastructure to deliver and support new company strategies and solutions and to service new clients. A substantial portion of these costs relate to personnel and third-party service providers.

Page 27 of 39

•

In the six months ended June 30, 2006, we determined that the front-end component of the SEI Advisor Desktop did not meet the expected functionality requirements and would require additional investment. $3.4 million of software development costs was written-off and is reflected in the Investment Advisors segment. Additionally, $2.3 million in previously capitalized software development costs for the Global Wealth Platform was written-off and affected all of our business segments except LSV.

•

We continued our stock repurchase program during 2007 and purchased approximately 2,683,000 shares at an average price of approximately $29 per share in the second quarter and 4,170,000 shares at an average price of approximately $30 per share in the six month period.

•

In the six month period of 2007, our net income was unfavorably impacted by an increase in our effective tax rate. Our effective tax rate was 37.6 percent for the six months ended June 30, 2007 as compared to 34.4 percent for the similar period of 2006.

Minority interest includes the amount owned by other shareholders in which we have a significant or controlling interest. The accounts of these entities are included in our consolidated financial statements. Minority interest consists of the following:


	Three Months Ended June 30,						Six Months Ended June 30,
	2007			2006			2007			2006
LSV Asset Management	$	(48,861	)	$	(36,573	)	$	(91,533	)	$	(70,866	)

Total minority interest	$	(47,242	)	$	(35,171	)	$	(87,976	)	$	(68,127	)

Net gain (loss) from investments consists of the following:


	Three Months Ended June 30,						Six Months Ended June 30,
	2007			2006			2007			2006
Realized gain from sales of marketable securities	$	4		$	1,681		$	4		$	1,901
(Decrease) increase in fair value of derivative financial instruments		(659	)		383			(1,104	)		(82	)
Other realized losses		(342	)		(1,462	)		(213	)		(1,459	)

Net gain (loss) from investments	$	(997	)	$	602		$	(1,313	)	$	360

Derivative financial instruments are used to minimize the price risk associated with changes in the fair value of our seed investments in new investment management programs. These derivative financial investments did not qualify for hedge accounting under current accounting rules. As a result, changes in the fair value of these derivative financial instruments were recorded in current period earnings whereas the change in the fair value of the hedged asset will be realized upon sale in future period earnings. Management’s decision to enter into derivative financial instruments that do not qualify for hedge accounting may cause volatility in quarterly earnings (See Note 5 to the Consolidated Financial Statements).

Page 30 of 39

Other realized losses in the three and six month periods of 2007 and 2006 include write-downs of approximately $500 thousand and $1.5 million, respectively, related to an investment in a private company. The write down in 2007 represented the remaining balance of the investment in the company.

Other includes a one-time gain of approximately $3.0 million recognized from the sale of our remaining ownership in a joint-venture.

Interest income is earned based upon the amount of cash that is invested daily. The increase in interest income in the six month period of 2007 compared to 2006 resulted from higher cash balances and an increase in interest rates.

Stock-Based Compensation

Our stock options have performance vesting conditions based on the attainment of certain earnings per share targets established at the date of grant. The first performance condition determines vesting of 50 percent of the options, and a second performance condition determines the vesting of the remaining 50 percent of the options. The performance conditions are measured annually on December 31. Options granted prior to 2006 also could vest in their entirety seven years from the date of grant. The amount of stock-based compensation expense is based upon our estimates of when we believe the earnings per share targets may be achieved. If factors change and we employ different assumptions for estimating stock-based compensation expense in future periods, or if we decide to use a different valuation model, future periods may differ significantly from what we have recorded in the current period. If our estimate of the attainment of the earnings per share targets proves to be inaccurate, the remaining amount of stock-based compensation expense could be accelerated, spread out over a longer period, or reversed. This may cause volatility in the recognition of stock-based compensation expense in future periods and could materially affect our net income and net income per share. During the three month period ended June 30, 2007, we accelerated the recognition of $580 thousand in stock-based compensation expense due to a change in management’s estimate of when certain vesting targets are expected to be achieved. In the first six months of 2007, we recognized approximately $13.5 million in stock-based compensation expense. Based upon our current view of how many options will vest and when they will vest, we estimate that stock-based compensation expense will be recognized according to the following schedule:


Period	Stock-Based Compensation Expense
Remainder of 2007	$	13,628
2008		14,273
2009		7,229
2010		3,857
2011		3,857
2012		3,815
2013		1,975

	$	48,634

Income Taxes

Our effective tax rates were 38.0 percent and 32.1 percent for the three months ended June 30, 2007 and 2006, respectively. For the six months ended June 30, 2007 and 2006, our effective tax rates were 37.6 percent and 34.4 percent, respectively. The increase in effective tax rates was primarily due to an increase in the effective state tax rate. The tax rate in the second quarter of 2006 was favorably impacted from state income tax planning which provided a cumulative benefit in that quarter.

New Accounting Pronouncements

In September 2006, the FASB issued FASB Statement No. 157 (SFAS 157), “Fair Value Measurements.” SFAS 157 establishes a framework for measuring fair value in generally accepted accounting principles and expands disclosures about fair value measurements. SFAS 157 is effective for all financial statements issued for fiscal years beginning after November 15, 2007. We do not expect the adoption of SFAS 157 to have a material impact on our financial statements.

Page 31 of 39

In February 2007, the FASB issued FASB Statement No. 159 (SFAS 159), “The Fair Value Option for Financial Assets and Financial Liabilities.” SFAS 159 permits companies to choose to measure certain financial instruments and certain other items at fair value. The standard requires that unrealized gains and losses on items for which the fair value option has been elected be reported in earnings. SFAS 159 is effective for all financial statements issued for fiscal years beginning after November 15, 2007. We are currently evaluating the impact that SFAS 159 will have on our financial statements.

Liquidity and Capital Resources


	For the Six Months Ended June 30,
	2007			2006
Net cash provided by operating activities	$	133,450		$	166,036
Net cash used in investing activities		(54,620	)		(50,561	)
Net cash used in financing activities		(119,486	)		(68,319	)

Net increase in cash and cash equivalents		(40,656	)		47,156

Cash and cash equivalents, beginning of period		286,948			130,128

Cash and cash equivalents, end of period	$	246,292		$	177,284

Cash requirements and liquidity needs are primarily funded through our cash flow from operations and our capacity for additional borrowing. At June 30, 2007, our unused sources of liquidity consisted of unrestricted cash and cash equivalents of $246.3 million and the full amount available through a credit facility of $200.0 million which was scheduled to expire in September 2007. In July 2007, we replaced the credit facility. The new credit facility agreement provides for borrowings of up to $200.0 million and expires in July 2012. The availability of the new credit facility is subject to the compliance with certain covenants set forth in the agreement.

Cash flows from operations decreased $32.6 million in 2007 compared to 2006. Cash flows in 2006 were significantly affected by the requirement to consolidate the accounts of LSV and LSV Employee Group, which increased net cash provided by operating activities by $52.1 million. An increase in net income favorably affected cash flows in 2007, but was offset by the net change in our working capital accounts.

Net cash used in investing activities primarily includes the capitalization of costs incurred in developing computer software, purchases and sales of marketable securities, and capital expenditures. Capitalized software development costs were $35.7 million in 2007 as compared to $36.8 million in 2006. The Global Wealth Platform was placed into service in July 2007. Capitalized software development costs of $199.6 million will be amortized over 15 years beginning in the third quarter of 2007. We will continue to incur significant development costs as enhancements and upgrades to expand the functionality of the Global Wealth Platform are developed and implemented. We expect to incur expenses related to maintenance and training as we enter the operational stage in the development of the platform.

We had $6.7 million and $3.4 million in net purchases of marketable securities in 2007 and 2006, respectively. Purchases of marketable securities in 2007 mainly comprised investments for the start-up of new investment products. Capital expenditures in 2007 and 2006 primarily include the expansion of our corporate headquarters. The total cost of the expansion is estimated to be at least $24.4 million and is expected to be completed in the third quarter of 2007. Through June 30, 2007, we have spent approximately $22.4 million related to the expansion project, of which $7.4 million was spent in the first six months of 2007.

Net cash used in financing activities primarily includes principal payments of our debt, the repurchase of our common stock and dividend payments. Principal payments on our debt were $4.0 million in 2007 and $9.2 million in 2006. Principal payments made by LSV Employee Group for amounts included in our debt were $9.0 million in 2007. We made our final payment for the Series A Senior Notes in the first quarter of 2007. As of June 30, 2007, the outstanding balance on our Senior Notes was $5.0 million, of which $1.0 million is classified as current.

Our Board of Directors has authorized the repurchase of up to $1.3 billion worth of our common stock. Through

Page 32 of 39

July 31, 2007, we repurchased approximately 245.7 million shares of our common stock at a cost of $1.2 billion and had $87.3 million of authorization remaining for the purchase of our common stock under this program. We spent approximately $124.7 million during the first six months of 2007 and $68.4 million during the first six months of 2006 for the repurchase of our common stock. Currently, there is no expiration date for our common stock repurchase program.

Cash dividends paid were $25.7 million or $.13 per share in the first six months of 2007 and $22.7 million or $.11 per share in the first six months of 2006. Our Board of Directors intends to declare future dividends on a semi-annual basis.

We believe our operating cash flow, available borrowing capacity, and existing cash and cash equivalents should provide adequate funds for continuing operations; continued investment in new products and equipment; our common stock repurchase program; expansion of our corporate campus; future dividend payments; and principal and interest payments on our long-term debt.

Significant Agreement

On January 24, 2006, we entered into a Guaranty and Collateral Agreement with LSV Employee Group, LaSalle Bank National Association and certain other lenders. We entered into the agreement in order to facilitate the acquisition of certain partnership interests of LSV by LSV Employee Group. Additional information pertaining to the agreement is presented in Note 2 of the Notes to the Consolidated Financial Statements included in the Company’s Annual Report on Form 10-K for 2006. There have been no material changes in the terms or conditions of the agreement from those disclosed in our Annual Report on Form 10-K for 2006.

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;

•

the performance of the funds we manage;

•

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

•

the affect of extensive governmental regulation;

•

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;

•

risk of failure by a third-party service provider;

•

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 adviser, 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 National Association of Securities Dealers 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

Page 33 of 39

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 have responded and are currently responding to various regulatory examinations, inquiries and 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. These activities resulted in an increased level of corporate overhead costs. One of these regulatory requests and inquiries relate to the payment by certain of our subsidiaries of expenses related to the marketing and distribution of shares of certain mutual fund clients of our fund administration and distribution business. A similar inquiry recently resulted in an SEC order sanctioning one of our mutual fund administrator competitors. Given the fact-specific nature of the practices relating to the marketing and distribution of fund shares, we cannot infer from the competitor’s order involving the competitor’s practices what the ultimate resolution of this SEC inquiry into the Company’s practices will be.

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. Directed brokerage payment arrangements offered by us are also subject to the SEC and other federal regulatory authorities. Changes in the regulation of directed brokerage or soft dollar payment arrangements or strategic decisions of our clients regarding these arrangements could affect sales of some services, primarily our brokerage services.

Item 3.

Quantitative and Qualitative Disclosures About Market Risk.

Interest Rate Risk - Our exposure to changes in interest rates primarily relates to our investment portfolio. Our excess cash is principally invested in short-term, highly liquid financial instruments, mainly money market funds, with a substantial portion of such investments having initial maturities of three months or less. Our investment portfolio includes U.S. Treasury securities maturing within one year, a long-term fixed-income mutual fund principally invested in U.S. government agency securities, and a short-term mutual fund principally invested in securities of U.S. and foreign commercial banks and government agencies. We place our investments in financial instruments that meet high credit quality standards. While changes in interest rates could decrease interest income, we do not believe that we have a material exposure to changes in interest rates. We do not undertake any specific actions to cover our exposure to interest rate risk and are not a party to any interest rate risk management transactions.

Additionally, LSV Employee Group entered into two interest rate swap agreements to convert its floating rate long-term debt to fixed rate debt. These swaps have a total notional value of $47.5 million. Payments are made every 90 days and the termination dates of the swaps are March 2009 and January 2011. The net effect from the interest rate swaps on the Company’s earnings was minimal.

Foreign Currency Risk - We transact business in the local currencies of various foreign countries, principally Canada, Ireland, the United Kingdom and South Korea. The total of all of our foreign operations accounts for approximately 11 percent of total consolidated revenues. Also, most of our foreign operations match local currency revenues with local currency costs. Due to these reasons, we do not, at this time, hedge against foreign operations.

Price Risk - We are exposed to price risk associated with changes in the fair value of investments in marketable securities relating to the startup of new pooled investment offerings. The length of time that our funds remain invested in these new pooled investment offerings is dependent on client subscriptions. We will redeem our investments as clients subscribe to these new investment offerings. To provide protection against potential fair value changes for these investments, we have entered into various derivative financial instruments. As of June 30, 2007, we held derivative financial instruments with a notional amount of $9.5 million and an expected maturity in 2007. Changes in the fair value of the derivative financial instruments are recognized in current period earnings, whereas, the change in the fair value of the investment is recorded on the balance sheet in other comprehensive income. Therefore, changes in the fair value of the derivative financial instrument and changes in the fair value of the investment are not recognized through earnings in the same period. We did not enter into or hold any derivative financial instruments for trading purposes during 2007 or 2006.

Income before income taxes include losses of $1.1 million and $82 thousand in the six month periods of 2007 and 2006, respectively, relating to changes in the fair value of derivative financial instruments. The aggregate effect of a hypothetical ten percent change in the fair value of our investments would be:


	Hypothetical Change In Value
Investment	Hypothetical Change In Value
Mutual Funds	$	6,524
Debt securities		449
Equities securities		973

	$	7,946

In consideration of the hypothetical change in value, our derivative financial instruments related to equities would substantially offset the change in fair value of the equity securities.

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 functioning effectively to provide reasonable assurance that the information required to be disclosed by us in reports filed under the Securities Exchange Act of 1934 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 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, 2007 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.

On September 30, 2004, SIDCO was named as a defendant in a putative consolidated amended class action complaint (the “PBHG Complaint”) filed in the United States District Court for the District of Maryland titled “Stephen Carey v. Pilgrim Baxter & Associates, LTD, et. al.” The PBHG Complaint was purportedly made on behalf of all persons that purchased or held PBHG mutual funds during the period from November 1, 1998 to November 13, 2003 and related generally to various market timing practices allegedly permitted by the PBHG Funds. The suit named as defendants some 36 persons and entities, including various persons and entities affiliated with Pilgrim Baxter & Associates, Ltd., various PBHG Funds, various alleged market timers, various alleged facilitating brokers, various clearing brokers, various banks that allegedly financed the market timing activities, various distributors/underwriters and others. The PBHG Complaint alleged that SIDCO was the named distributor/underwriter from November 1998 until July 2001 for various PBHG funds in which market timing allegedly occurred during that period. The PBHG Complaint generally alleged that the prospectus for certain PBHG funds made misstatements and omissions concerning market timing practices in PBHG funds. The PBHG Complaint alleged that SIDCO violated Sections 11 and 12(a)(2) of the Securities Act of 1933, Section 10(b) of the Securities Exchange Act of 1934 and Rule 10b-5 thereunder, and Sections 34(b) and 36(a) of the Investment Company Act of 1940, and that SIDCO breached its fiduciary duties, engaged in constructive fraud and aided and abetted the breach by others of their fiduciary duties. The PBHG Complaint did not name SIDCO or any of its affiliates as a market timer, facilitating or clearing broker or financier of market timers. The PBHG Complaint sought unspecified compensatory and punitive damages, disgorgement and restitution. In 2006, the plaintiffs submitted a proposed form of order dismissing SIDCO from the action, but the Court has not yet acted on the proposed order.

Item 1A.

Risk Factors

Information regarding risk factors appears in Part I - Item 1A of the Company’s Annual Report on Form 10-K for the year ended December 31, 2006. There have been no material changes in our risk factors from those disclosed in our Annual Report on Form 10-K for 2006.

Item 2.
