Note 1. Summary of Significant Accounting Policies

Nature of Operations

SEI Investments Company (the Company), a Pennsylvania corporation, provides investment processing, investment management, and investment operations platforms to financial institutions, financial advisors, institutional investors, investment managers and ultra-high-net-worth families in the United States, Canada, the United Kingdom, continental Europe and various other locations throughout the world.

Investment processing platforms consist of application and business process outsourcing services, professional services and transaction-based services. Revenues from investment processing platforms are recognized in Information processing and software servicing 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.

Investment operations platforms offer investment managers support for traditional investment products such as mutual funds, collective investment trusts, exchange-traded funds, and institutional and separate accounts, by providing outsourcing services including fund and investment accounting, administration, reconciliation, investor servicing and client reporting. These platforms also provide support to managers focused on alternative investments who manage hedge funds, funds of hedge funds, private equity funds and real estate funds, across registered, partnership and separate account structures domiciled in the United States and overseas. Revenues from investment operations platforms 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 have 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 March 31, 2018, the results of operations for the three months ended March 31, 2018 and 2017, and cash flows for the three-month periods ended March 31, 2018 and 2017. 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, 2017.

The Company adopted the requirements of Accounting Standards Update (ASU) No. 2014-09, Revenue from Contracts with Customers (Topic 606) (Accounting Standards Codification (ASC) 606 (ASC 606)) using the modified retrospective method during the three months ended March 31, 2018. As a result of the adoption of ASC 606, the Company recorded a cumulative effect adjustment of $14,402 to retained earnings as of January 1, 2018. Prior period information has not been restated (see following caption "Revenue Recognition"). The Company also adopted ASU No. 2016-01, Recognition and Measurement of Financial Assets and Financial Liabilities (see Note 6) and ASU No. 2016-18, Statement of Cash Flows, Restricted Cash (Topic 230) (see following caption "Statements of Cash Flows"). All amounts and disclosures set forth in this Form 10-Q have been updated to comply with the new standards.

Revenue Recognition

Revenue is recognized when the transfer of control of promised goods or services under the terms of a contract with customers are satisfied in an amount that reflects the consideration to which the Company expects to be entitled in exchange for those promised goods or services. Certain portions of the Company’s revenues involve a third party in providing goods or services to its customers. In such circumstances, the Company must determine whether the nature of its promise to the customer is to provide the underlying goods or services (the Company is the principal in the transaction and reports the transaction gross) or to arrange for a third party to provide the underlying goods or services (the entity is the agent in the transaction and reports the transaction net).

ASC 606 did not change the accounting for the majority of the Company’s revenue arrangements and did not have a material impact to the Company’s consolidated financial statements. The following is a summary of the impact from the adoption of ASC 606:

7 of 38

•The majority of the Company’s services are bundled together, and provided and completed for the client on a monthly basis. For these revenue arrangements, the Company will continue to recognize revenue on a monthly basis as the client consumes the benefits continuously over time. The timing and recognition of revenues from these arrangements did not change.

•Contracts with new clients or with existing clients for new services generally include implementation fees. These fees are recognized in Information processing and software servicing fees when in connection with investment processing platforms and are recognized in Asset management, administration and distribution fees when in connection with investment operations platforms. The Company concluded that most of the current arrangements for implementation services are a distinct and separate performance obligation from the monthly recurring services. The timing and recognition of fees for most of these arrangements have not changed. However, each new revenue arrangement for implementation fees is analyzed to determine whether or not it is a distinct performance obligation. Implementation fees determined not to be a distinct performance obligation would be required to be recognized over the expected life of the client relationship along with the costs relating directly to satisfying such performance obligation. The Company will evaluate each contract in accordance with the requirements of ASC 606.

•Research services provided by SIDCO, the Company’s broker-dealer subsidiary, to customers in soft-dollar arrangements were determined to be a separate performance obligation. Research services provided by a broker-dealer may be internally generated or provided by a third party and paid directly by the broker-dealer on the customer’s behalf. It was determined that SIDCO is considered an agent since it does not control the research services before they are transferred to the customer. Therefore, fees received for research services should be recorded in revenues net of amounts paid for the soft dollar arrangement. These amounts paid by the Company were previously recorded gross as an expense and, beginning January 1, 2018, are recorded net of any revenue recognized. The amounts related to soft dollar arrangements during the three months ended March 31, 2018 and 2017 were $3,730 and $4,073, respectively.

•Incremental contract acquisition costs related to information processing contracts in the Private Banks segment and investment operations contracts in the Investment Managers segment will be deferred and recognized over the expected client life. These costs primarily consist of sales compensation payments to the Company's sales personnel. As a result, incremental contract acquisition costs are capitalized and subsequently amortized. The Company recorded a cumulative effect adjustment to retained earnings associated with the capitalization of contract costs. For the Company's other sales compensation payments, the Company either applies the practical expedient permitting the expensing of costs to obtain a contract when the expected amortization period is one year or less or there are no contract acquisition costs required to be deferred under the requirements of ASC 606.

Cash and Cash Equivalents

Cash and cash equivalents includes $341,413 and $401,292 at March 31, 2018 and December 31, 2017, respectively, primarily invested in SEI-sponsored open-ended money market mutual funds. The SEI-sponsored mutual funds are Level 1 assets.

Restricted Cash

Restricted cash includes $3,000 at March 31, 2018 and December 31, 2017 segregated for regulatory purposes related to trade-execution services conducted by SEI Investments (Europe) Limited. Restricted cash also includes $507 and $505 at March 31, 2018 and December 31, 2017, 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 (SEC) for broker-dealers.

Capitalized Software

The Company capitalized $12,887 and $16,861 of software development costs during the three months ended March 31, 2018 and 2017, respectively. The Company's software development costs primarily relate to the continued development of the SEI Wealth Platform^SM(the Platform). The Company capitalized $12,042 and $15,178 of software development costs for significant enhancements to the Platform during the three months ended March 31, 2018 and 2017, respectively. As of March 31, 2018, the net book value of the Platform was $287,530. The net book value includes $33,237 of capitalized software development costs in-progress associated with future releases. The Platform has a weighted average remaining life of 8.4 years. Amortization expense for the Platform was $9,719 and $11,972 during the three months ended March 31, 2018 and 2017, respectively.

The Company also capitalized $845 and $1,683 of software development costs during the three months ended March 31, 2018 and 2017, respectively, related to an application for the Investment Managers segment. The application was placed into service during the first quarter 2018 with an estimated useful life of 5 years. The net book value of the application at March 31, 2018 was $24,742. Amortization expense for the application was $1,301 during the three months ended March 31, 2018.

Earnings per Share

The calculations of basic and diluted earnings per share for the three months ended March 31, 2018 and 2017 are:



	Three Months Ended March 31,
	2018		2017
Net income	$	139,838	$	88,737
Shares used to compute basic earnings per common share	157,434,000		159,091,000
Dilutive effect of stock options	5,990,000		3,651,000
Shares used to compute diluted earnings per common share	163,424,000		162,742,000
Basic earnings per common share	$	0.89	$	0.56
Diluted earnings per common share	$	0.86	$	0.55

During the three months ended March 31, 2018 and 2017, employee stock options to purchase 6,054,000 and 11,279,000 shares of common stock with an average exercise price of $52.73 and $37.70, respectively, were outstanding but not included in the computation of diluted earnings per common share. These options for the three month periods were not included in the computation of diluted earnings per common share because either the performance conditions have not been satisfied or would have been satisfied if the reporting date was the end of the contingency period or the option’s exercise price 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.

Reclassifications

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

New Accounting Pronouncements

In February 2016, the FASB issued ASU No. 2016-02, Leases (ASU 2016-02) requiring lessees to recognize a right-of-use asset and a lease liability on the balance sheet for all leases with the exception of short-term leases. For lessees, leases will continue to be classified as either operating or finance leases in the income statement. Lessor accounting is similar to the current model but updated to align with certain changes to the lessee model. Lessors will continue to classify leases as operating, direct financing or sales-type leases. The updated standard is effective for the Company beginning in the first quarter of 2019. Early adoption is permitted. While the Company is not yet in a position to assess the full impact of the adoption of ASU 2016-02 on its consolidated financial statements and related disclosures, the Company is currently in the process of cataloging existing lease agreements and evaluating the transition method to be elected.

In June 2016, the FASB issued ASU No. 2016-13, Financial Instruments-Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments (ASU 2016-13) which requires that expected credit losses relating to financial assets measured on an amortized cost basis and available-for-sale debt securities be recorded through an allowance for credit losses. ASU 2016-13 limits the amount of credit losses to be recognized for available-for-sale debt securities to the amount by which carrying value exceeds fair value and also requires the reversal of previously recognized credit losses if fair value increases. ASU 2016-13 becomes effective for the Company during the first quarter of 2020. Early adoption is permitted. The Company is currently evaluating the effect that the updated standard will have on its consolidated financial statements and related disclosures.

In January 2017, the FASB issued ASU 2017-04, Simplifying the Test for Goodwill Impairment (ASU 2017-04). The objective of ASU 2017-04 is to simplify the subsequent measurement of goodwill by entities performing their annual goodwill impairment tests by comparing the fair value of a reporting unit, including income tax effects from any tax-deductible goodwill, with its carrying amount and recognizing an impairment charge for the amount by which the carrying amount exceeds fair value. ASU 2017-04 is effective for the Company beginning in the first quarter of 2020. Early adoption is permitted. The Company is currently evaluating the impact of adopting ASU 2017-04 on its consolidated financial statements and related disclosures.

Statements of Cash Flows

For purposes of the Consolidated Statements of Cash Flows, the Company considers investment instruments purchased with an original maturity of three months or less to be cash equivalents.

The Company adopted ASU No. 2016-18, Statement of Cash Flows, Restricted Cash (Topic 230) (ASU 2016-18) on January 1, 2018 which requires that a statement of cash flows explain the change during the period for the total of cash, cash equivalents, and amounts generally described as restricted cash or restricted cash equivalents. The prior period was retrospectively adjusted to conform to the current period’s presentation. There was no impact to net cash flows for the three months ended March 31, 2017 as a result of including restricted cash with cash and cash equivalents when reconciling the

9 of 38

beginning-of-period and end-of-period total amounts presented on the accompanying Consolidated Condensed Statement of Cash Flows in accordance with ASU 2016-18.

The following table provides the details of the adjustments to reconcile net income to net cash provided by operating activities for the three months ended March 31:

Note 2.	Investment in Unconsolidated Affiliate

LSV Asset Management

The Company has an investment in LSV Asset Management (LSV), a registered investment advisor that provides investment advisory services primarily to institutions, including pension plans and investment companies. LSV is currently an investment sub-advisor for a limited number of SEI-sponsored investment products. 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 Sheets and its interest in the earnings of LSV is reflected in Equity in earnings of unconsolidated affiliate on the accompanying Consolidated Statements of Operations.

At March 31, 2018, the Company’s total investment in LSV was $54,482. The Company receives partnership distributions from LSV on a quarterly basis. The Company received partnership distributions from LSV of $45,617 and $35,265 in the three months ended March 31, 2018 and 2017, respectively. As such, the Company considers these distribution payments as returns on investment rather than returns of the Company's original investment in LSV and has therefore classified the associated cash inflows as an operating activity on the Consolidated Statements of Cash Flows.

The Company’s proportionate share in the earnings of LSV was $40,607 and $33,565 during the three months ended March 31, 2018 and 2017, respectively.

Note 3. Variable Interest Entities – Investment Products

The Company or its affiliates have 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. The Company receives asset management, distribution, administration and custodial fees for these services. Clients are the equity investors and participate in proportion to their ownership percentage in the net income or loss and net capital gains or losses of the products, and, on liquidation, will participate in proportion to their ownership percentage in the remaining net assets of the products after satisfaction of outstanding liabilities.

The Company has concluded that it is not the primary beneficiary of the entities and; therefore, is not required to consolidate any of the pooled investment vehicles for which it receives asset management, distribution, administration and custodial fees under the VIE model. The entities either do not meet the definition of a VIE or the Company does not hold a variable interest in the entities. The entities either qualify for the money market scope exception, or are entities in which the Company’s asset management, distribution, administration and custodial fees are commensurate with the services provided and include fair terms and conditions, or are entities that are limited partnerships which have substantive kick-out rights. The Company acts as a fiduciary and does not hold any other interests other than insignificant seed money investments in the pooled investment vehicles. For this reason, the Company also concluded that it is not required to consolidate the pooled investment vehicles under the voting interest entity (VOE) model.

The Company is a party to expense limitation agreements with certain SEI-sponsored money market funds subject to Rule 2a-7 of the Investment Company Act of 1940 which establish a maximum level of ordinary operating expenses incurred by the fund in any fiscal year including, but not limited to, fees of the administrator or its affiliates. Under the terms of these agreements, the Company waived $6,654 and $7,072 in fees during the three months ended March 31, 2018 and 2017, respectively.

Note 5. Fair Value Measurements

The fair value of the Company’s financial assets and liabilities, except for the Company's investment funds sponsored by LSV, is determined in accordance with the fair value hierarchy. The fair value of the Company’s Level 1 financial assets consist mainly of investments in open-ended mutual funds that are quoted daily. Level 2 financial assets consist of Government National Mortgage Association (GNMA) mortgage-backed securities held by the Company's wholly-owned limited purpose federal thrift subsidiary, SEI Private Trust Company (SPTC), Federal Home Loan Bank (FHLB) and other U.S. government agency short-term notes held by SIDCO. The financial assets held by SIDCO were purchased as part of a cash management program requiring only short term, top-tier investment grade government and corporate securities. The financial assets held by SPTC are debt securities issued by GNMA and are backed by the full faith and credit of the U.S. government. These securities were purchased for the sole purpose of satisfying applicable regulatory requirements and have maturity dates which range from 2021 to 2041.

The fair value of the Company's investment funds sponsored by LSV is measured using the net asset value per share (NAV) as a practical expedient. The NAVs of the funds are calculated by the funds' independent custodian and are derived from the fair values of the underlying investments as of the reporting date. The funds allow for investor redemptions at the end of each calendar month. This investment has not been classified in the fair value hierarchy but is presented in the tables below to permit reconciliation to the amounts presented on the accompanying Consolidated Balance Sheets.

12 of 38

The valuation of the Company's Level 2 financial assets held by SIDCO and SPTC are based upon securities pricing policies and procedures utilized by third-party pricing vendors.

The pricing policies and procedures applied for our Level 1 and Level 2 financial assets during the three months ended March 31, 2018 were consistent with those as described in our Annual Report on Form 10-K at December 31, 2017. The Company had no Level 3 financial assets or liabilities at March 31, 2018 or December 31, 2017 that were required to be measured at fair value on a recurring basis. There were no transfers of financial assets between levels within the fair value hierarchy during the three months ended March 31, 2018.

The fair value of certain financial assets of the Company was determined using the following inputs:



			Fair Value Measurements at the End of the Reporting Period Using
Assets	March 31, 2018		Quoted Prices in Active Markets for Identical Assets (Level 1)		Significant Other Observable Inputs (Level 2)

The Company adopted ASU No. 2016-01, Recognition and Measurement of Financial Assets and Financial Liabilities (ASU 2016-01) on January 1, 2018 which requires the Company to recognize all changes in fair value of available-for-sale equity securities in current period earnings. Previously, these changes in fair value were recognized as a separate component of comprehensive income. The adoption of ASU 2016-01 did not have a material impact to the Company's consolidated financial statements.

Net unrealized losses at March 31, 2018 and December 31, 2017 of the Company's available-for-sale debt securities were $2,016 (net of income tax benefit of $642) and $779 (net of income tax benefit of $233), respectively. These net unrealized losses are reported as a separate component of Accumulated other comprehensive loss on the accompanying Consolidated Balance Sheets.

There were no material realized gains or losses from available-for-sale securities during the three months ended March 31, 2018 and 2017. Gains and losses from available-for-sale securities, including amounts reclassified from accumulated comprehensive loss, are reflected in Net (loss) gain from investments on the accompanying Consolidated Statements of Operations.

Investments in Affiliated Funds

The Company has an investment in funds sponsored by LSV. The Company records this investment on the accompanying Consolidated Balance Sheets at fair value. Unrealized gains and losses from the change in fair value of these funds are recognized in Net (loss) gain from investments on the accompanying Consolidated Statements of Operations.

The investment primarily consists of U.S. dollar denominated funds that invest primarily in securities of Canadian, Australian and Japanese companies as well as various other global securities. The underlying securities held by the funds are translated into U.S. dollars within the funds. The funds had a fair value of $5,534 and $6,034 at March 31, 2018 and December 31, 2017, respectively. The Company recognized losses of $500 and gains of $298 during the three months ended March 31, 2018 and 2017, respectively, from the change in fair value of the funds.

Securities Owned

The Company’s broker-dealer subsidiary, SIDCO, has investments in U.S. government agency securities with maturity dates less than one year. These investments are reflected as Securities owned on the accompanying Consolidated Balance Sheets. Due to specialized accounting practices applicable to investments by broker-dealers, the securities are reported at fair value and changes in fair value are recorded in current period earnings. The securities had a fair value of $21,600 and $21,526 at March 31, 2018 and December 31, 2017, respectively. There were no material net gains or losses related to the securities during the three months ended March 31, 2018 and 2017.

Note 7. Line of Credit

The Company has a five-year $300,000 Credit Agreement (the Credit Facility) with Wells Fargo Bank, National Association, and a syndicate of other lenders. The Credit Facility is scheduled to expire in June 2021, 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 rates that, at the Company's option, are based on a base rate (the Base Rate) plus a premium that can range from 0.25 percent to 1.00 percent or the London InterBank Offered Rate (LIBOR) plus a premium that can range from 1.25 percent to 2.00 percent depending on the Company’s Leverage Ratio (a ratio of consolidated indebtedness to consolidated EBITDA for the four preceding fiscal quarters, all as defined in the related agreement). The Base Rate is defined as the highest of a) the Federal Funds Rate, as published by the Federal Reserve Bank of New York, plus 0.50 percent, b) the prime commercial lending rate of Wells Fargo, c) the applicable LIBOR plus 1.00 percent, or d) 0 percent. The Company also pays quarterly commitment fees based on the unused portion of the Credit Facility. The quarterly fees for the Credit Facility can range from 0.15 percent of the amount of the unused portion to 0.30 percent, depending on the Company’s Leverage Ratio. Certain wholly-owned subsidiaries of the Company have guaranteed the obligations of the Company under the agreement. The aggregate amount of the Credit Facility may be increased by an additional $100,000 under certain conditions set forth in the agreement.

14 of 38

The Credit Facility 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 the covenants of the Credit Facility negatively affect the Company’s liquidity or capital resources. 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 agreement may be terminated.

In July 2017, the Company borrowed $40,000 under the Credit Facility for the funding of an acquisition. As of March 31, 2018, the outstanding balance of the Credit Facility was $20,000 and is included in Borrowings Under Revolving Credit Facility on the accompanying Consolidated Balance Sheet. The Company was in compliance with all covenants of the Credit Facility during the three months ended March 31, 2018.

In April 2018, the Company made a principal payment of $20,000 to fully repay the outstanding balance of the Credit Facility. As of April 19, 2018, the amount of the Credit Facility that is available for general corporate purposes was $300,000.

Note 8. Shareholders’ Equity

Stock-Based Compensation

The Company has only non-qualified stock options outstanding under its equity compensation plans. 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 a specified diluted earnings per share target is achieved, and the remaining 50 percent when a second, higher specified diluted earnings per share target is achieved. Options do not vest due to the passage of time but solely as a result of achievement of the financial vesting targets. Options granted in December 2017 include a service condition which requires a minimum two or four year waiting period from the grant date along with the attainment of the applicable financial vesting target. Earnings per share targets exclude the impact of stock-based compensation and are established at time of grant. The targets are measured annually on December 31. The amount of stock-based compensation expense recognized in the period is based upon management’s estimate of when the earnings per share targets may be achieved. Any change in management’s estimate could result in the remaining amount of stock-based compensation expense to 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 the Company’s earnings.

The Company recognized stock-based compensation expense in its Consolidated Financial Statements in the three months ended March 31, 2018 and 2017, respectively, as follows:



	Three Months Ended March 31,
	2018			2017
Stock-based compensation expense	$	5,195		$	6,180
Less: Deferred tax benefit	(1,103		)	(2,153		)
Stock-based compensation expense, net of tax	$	4,092		$	4,027

As of March 31, 2018, there was approximately $56,579 of unrecognized compensation cost remaining related to unvested employee stock options that management expects will vest and is being amortized.

The Company issues new common shares associated with the exercise of stock options. The total intrinsic value of options exercised during the three months ended March 31, 2018 was $93,668. The total options exercisable as of March 31, 2018 had an intrinsic value of $393,003. The total intrinsic value for options exercisable is calculated as the difference between the market value of the Company’s common stock as of March 31, 2018 and the weighted average exercise price of the shares. The market value of the Company’s common stock as of March 31, 2018 was $74.91 as reported by the Nasdaq Stock Market, LLC. The weighted average exercise price of the options exercisable as of March 31, 2018 was $29.20. Total options that were outstanding as of March 31, 2018 were 14,652,000. Total options that were exercisable as of March 31, 2018 were 8,598,000.

Common Stock Buyback

The Company’s Board of Directors, under multiple authorizations, has authorized the repurchase of the Company’s common stock on the open market or through private transactions. The Company purchased 1,122,000 shares at a total cost of $82,257 during the three months ended March 31, 2018, which reduced the total shares outstanding of common stock. The cost of stock purchases during the period includes the cost of certain transactions that settled in the following quarter. As of March 31, 2018, the Company had approximately $88,380 of authorization remaining for the purchase of common stock under the program.

15 of 38

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.

Note 9. Accumulated Other Comprehensive Loss

The components of Accumulated other comprehensive loss, net of tax, are as follows:



	Foreign Currency Translation Adjustments			Unrealized Gains (Losses) on Investments			Accumulated Other Comprehensive Loss

Note 11. Income Taxes

The gross liability for unrecognized tax benefits at March 31, 2018 and December 31, 2017 was $14,685 and $14,480, respectively, exclusive of interest and penalties, of which $13,986 and $13,737 would affect the effective tax rate if the Company were to recognize the tax benefit.

17 of 38

The Company classifies interest and penalties on unrecognized tax benefits as income tax expense. As of March 31, 2018 and December 31, 2017, the combined amount of accrued interest and penalties related to tax positions taken on tax returns was $1,218 and $1,175, respectively.



	March 31, 2018		December 31, 2017
Gross liability for unrecognized tax benefits, exclusive of interest and penalties	$	14,685	$	14,480
Interest and penalties on unrecognized benefits	1,218		1,175
Total gross uncertain tax positions	$	15,903	$	15,655
Amount included in Current liabilities	$	2,944	$	3,275
Amount included in Other long-term liabilities	12,959		12,380
	$	15,903	$	15,655

The Company's effective income tax rate for the three months ended March 31, 2018 and 2017 differs from the federal income tax statutory rate due to the following:



	Three Months Ended March 31,
	2018		2017
Statutory rate	21.0	%	35.0	%
State taxes, net of federal tax benefit	2.2		1.5
Foreign tax expense and tax rate differential	(0.2	)	(0.8	)
Tax benefit from stock option exercises	(10.8	)	(4.2	)
Other, net	(0.3	)	(0.5	)
	11.9	%	31.0	%

The decrease in the tax rate for the three months ended March 31, 2018 was primarily due to the tax changes enacted in the 2017 Tax Cut and Jobs Act (The Tax Act). The Tax Act was enacted on December 22, 2017 and included a permanent reduction in the corporate tax rate from 35.0 percent to 21.0 percent. In addition, the rate was favorably impacted by an increase in the excess tax benefits recognized on stock-based compensation expense due to a higher volume of stock option exercise activity.

The Tax Act also imposed a territorial rather than worldwide system which requires a one-time transition tax on the repatriation of previously deferred foreign earnings. The Company's estimate of the one-time transition tax as of March 31, 2018 was $11,544, of which $915 is expected to be paid within one year and $10,629 is included in Long-term income taxes payable on the accompanying Consolidated Balance Sheet.

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. The Company is no longer subject to U.S. federal income tax examination for years before 2014 and is no longer subject to state, local or foreign income tax examinations by authorities for years before 2013.

The Company estimates it will recognize $2,944 of gross unrecognized tax benefits. This amount is expected to be paid within one year or to be removed at the expiration of the statute of limitations and resolution of income tax audits and is netted against the current payable account. 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 the 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.

18 of 38

Trust Company. Two of the actions also include claims for violations of the Louisiana Racketeering Act and possibly conspiracy, and a third also asserts claims of negligence, breach of contract, breach of fiduciary duty, violations of the uniform fiduciaries law, negligent misrepresentation, detrimental reliance, violations of the Louisiana Racketeering Act, and conspiracy.

The procedural status of the seven cases varies. The Lillie case, filed originally in the 19th Judicial District Court for the Parish of East Baton Rouge, was brought as a class action and is procedurally the most advanced of the cases. SEI and SPTC filed exceptions, which the Court granted in part, dismissing claims under the Louisiana Unfair Trade Practices Act and permitting the claims under the Louisiana Securities Law to go forward. On March 11, 2013, newly-added insurance carrier defendants removed the case to the United States District Court for the Middle District of Louisiana. On August 7, 2013, the Judicial Panel on Multidistrict Litigation transferred the matter to the Northern District of Texas where MDL 2099, In re: Stanford Entities Securities Litigation (“the Stanford MDL”), is pending. On September 22, 2015, the District Court on the motion of SEI and SPTC dismissed plaintiffs’ claims for primary liability under Section 714(A) of the Louisiana Securities Law, but declined to dismiss plaintiffs’ claims for secondary liability under Section 714(B) of the Louisiana Securities Law based on the allegations pled by plaintiffs. On November 4, 2015, the District Court granted SEI and SPTC's motion to dismiss plaintiffs' claims under Section 712(D) of the Louisiana Securities Law. Consequently, the only claims of plaintiffs still pending before the District Court in Lillie are plaintiffs' claims for secondary liability against SEI and SPTC under Section 714(B) of the Louisiana Securities Law. On May 2, 2016, the District Court certified the class as being "all persons for whom Stanford Trust Company purchased or renewed Stanford Investment Bank Limited certificates of deposit in Louisiana between January 1, 2007 and February 13, 2009". Notice of the pendency of the class action was mailed to potential class members on October 4, 2016.

On December 1, 2016, a group of plaintiffs who opted out of the Lillie class filed a complaint against SEI and SPTC in the United States District Court in the Middle District of Louisiana, alleging claims essentially the same as those in Lillie. In January 2017, the Judicial Panel on Multidistrict Litigation transferred the proceeding to the Northern District of Texas and the Stanford MDL. During February 2017, SEI filed its response to the Complaint and in March 2017 the District Court for the Northern District of Texas approved the stipulated dismissal of all claims in this complaint predicated on Section 712(D) or Section 714(A) of the Louisiana Securities Law.

Another one of the cases, filed in the 23rd Judicial District Court for the Parish of Ascension, also was removed to federal court and transferred by the Judicial Panel on Multidistrict Litigation to the Northern District of Texas and the Stanford MDL. The schedule for responding to that Complaint has not yet been established.

The plaintiffs in two of the cases remaining in the Parish of East Baton Rouge have granted SEI and SPTC indefinite extensions to respond to the petitions.

In the two additional cases, filed in East Baton Rouge and brought by the same counsel who filed the Lillie action, virtually all of the litigation to date has involved motions practice and appellate litigation regarding the existence of federal subjection matter jurisdiction under the federal Securities Litigation Uniform Standards Act (SLUSA). After the matter was removed to the United States District Court for the Northern District of Texas, that court dismissed the action under SLUSA. The Court of Appeals for the Fifth Circuit reversed that order, and the Supreme Court of the United States affirmed the Court of Appeals judgment on February 26, 2014. The matter was remanded to state court and no material activity has taken place since that date.

While the outcome of this litigation remains uncertain, SEI and SPTC believe that they have valid defenses to plaintiffs' claims and intend to defend the lawsuits vigorously. Because of uncertainty in the make-up of the Lillie class, the specific theories of liability that may survive a motion for summary judgment or other dispositive motion, the relative lack of discovery regarding damages, causation, mitigation and other aspects that may ultimately bear upon loss, the Company is not reasonably able to provide an estimate of loss, if any, with respect to the foregoing lawsuits.

Note 13. Goodwill and Intangible Assets

In July 2017, the Company acquired all ownership interests of Archway Technology Partners, LLC, Archway Finance & Operations, Inc. and Keystone Capital Holdings, LLC (collectively, Archway), a provider of operating technologies and services to the family office industry. The total purchase price was allocated to Archway’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 $52,990 and is included on the accompanying Consolidated Balance Sheets.

19 of 38

The Company identified intangible assets related to Archway that met the contractual-legal criterion for recognition apart from goodwill. The identifiable intangible assets included on the accompanying Consolidated Balance Sheets consist of:



	March 31, 2018			December 31, 2017
Acquired technology	$	13,510		$	13,510
Client relationships	10,760			10,760
Non-competition agreements	3,470			3,470
Trade name	2,390			2,390
	30,130			30,130
Less: Accumulated amortization	(2,328		)	(1,552		)
Intangible assets, net	$	27,802		$	28,578

The Company recognized $776 of amortization expense related to the intangible assets during the three months ended March 31, 2018. Goodwill and the identifiable intangible assets related to Archway have been allocated to the Investment Managers segment.

Note 14. Revenues from Contracts with Customers

The Company’s principal sources of revenues are: (1) asset management, administration and distribution fees primarily earned based upon a contractual percentage of net assets under management or administration; and (2) information processing and software servicing fees that are either recurring and primarily earned based upon the number of trust accounts being serviced or a percentage of the total average daily market value of the clients' assets processed on the Company's platforms, or non-recurring and based upon project-oriented contractual agreements related to client implementations.

Overview

Consolidated Summary

We are a leading global provider of investment processing, investment management and investment operations platforms. We help corporations, financial institutions, financial advisors and ultra-high-net-worth families create and manage wealth by providing comprehensive, innovative, investment and investment-business platforms. Investment processing fees are earned as monthly fees for contracted services, including computer processing services, software licenses and investment operations services, as well as transaction-based fees for providing securities valuation and trade-execution. Investment operations and investment management fees are earned as a percentage of average assets under management, administration or advised assets. As of March 31, 2018, through our subsidiaries and partnerships in which we have a significant interest, we manage, advise or administer $869.0 billion in hedge, private equity, mutual fund and pooled or separately managed assets, including $334.7 billion in assets under management and $530.1 billion in client assets under administration. Our affiliate, LSV Asset Management (LSV), manages $108.2 billion of assets which are included as assets under management.

* Variances noted "NM" indicate the percent change is not meaningful.

The following items had a significant impact on our financial results for the three months ended March 31, 2018 and 2017:

•

Revenue growth was primarily driven by higher Asset management, administration and distribution fees from market appreciation and positive cash flows from new and existing clients. Our average assets under management, excluding LSV, increased $32.2 billion, or 16 percent, to $233.6 billion in the first three months of 2018 as compared to $201.4 billion during the first three months of 2017. Our average assets under administration increased $56.4 billion, or 12 percent, to $530.3 billion in the first three months of 2018 as compared to $474.0 billion during the first three months of 2017.


•	Information processing and software servicing fees in our Private Banks segment increased $6.4 million during the first three months of 2018 primarily due to increased assets from new and existing clients processed on the SEI Wealth Platform.


•	Revenues from our acquisition of SEI Archway were $5.5 million during the first three months of 2018. SEI Archway was acquired during the third quarter 2017 and is reported in our Investment Managers segment.


•	Our proportionate share in the earnings of LSV increased to $40.6 million in the first three months of 2018 as compared to $33.6 million in the first three months of 2017 primarily due to increased assets under management from LSV's existing clients due to market appreciation.


•	Our operating expenses, primarily personnel costs, in our Investment Advisors and Investment Managers segments increased. These expenses primarily consist of operational, technology and marketing costs and are mainly related to servicing existing clients and acquiring new clients. In addition, our Investment Managers segment includes personnel

22 of 38

costs related to SEI Archway. These operating expenses are included in Compensation, benefits and other personnel costs on the accompanying Consolidated Statements of Operations.

•

The direct costs associated with our investment management programs increased in our Private Banks, Investment Advisors and Institutional Investors segments. These costs primarily relate to fees charged by investment advisory firms for day-to-day portfolio management of SEI-sponsored investment products. These costs are included in Sub-advisory, distribution and other asset management costs on the accompanying Consolidated Statements of Operations.

•

We capitalized $12.0 million in the first three months of 2018 for the SEI Wealth Platform as compared to $15.2 million in the first three months of 2017. Amortization expense related to the Platform decreased to $9.7 million during the first three months of 2018 as compared to $12.0 million during the first three months of 2017 due to the adjustment to the estimated useful life of the Platform effective in the fourth quarter 2017.


•	During the first three months of 2018, we placed into service an application developed for the Investment Managers segment. This new offering includes components that leverage upon the current infrastructure and add significant enhancements designed to aggregate, transact and process data. Amortization expense related to the application was $1.3 million during the first three months of 2018.


•	As we continue the development of new elements of the Platform, our expenses related to maintenance and support have increased. These costs are primarily recognized in personnel and consulting costs and are not eligible for capitalization. These increased costs primarily impacted the Private Banks and Investment Advisors business segments.

•

Our effective tax rate was 11.9 percent during the first three months of 2018 as compared to 31.0 percent during the first three months of 2017. The decline in our effective tax rate was primarily due to the tax changes enacted in the 2017 Tax Cut and Jobs Act (The Tax Act). In addition, the rate was favorably impacted by increased tax benefits due to a higher volume of stock option exercise activity (See the caption "Income Taxes" later in this discussion for more information).


•	We continued our stock repurchase program during 2018 and purchased 1.1 million shares for $82.3 million in the three month period.

Impact of Adopting Revenue Recognition Guidance

On January 1, 2018, we adopted Accounting Standards Update (ASU) No. 2014-09, Revenue from Contracts with Customers (Topic 606) (Accounting Standards Codification 606 (ASC 606), which provides accounting guidance on the recognition of revenues from contracts with customers and impacts the presentation of certain revenues and expenses in our Consolidated Statements of Operations. ASC 606 is applied prospectively from January 1, 2018 and reported financial results from the prior comparable period have not been revised.

ASC 606 did not change the accounting for the majority of our revenue arrangements and did not have a material impact to our consolidated financial statements. The impact from the adoption of ASC 606 to our financial results during the three months ended March 31, 2018 is primarily related to research services provided to customers in soft-dollar arrangements by SIDCO, our broker-dealer subsidiary. Under the new revenue standard, fees received for research services by SIDCO are recorded net of amounts paid for the soft dollar arrangement. The amounts we paid under these arrangements were previously recorded as an expense. The impact of this change in presentation was a decline in both revenues and expenses of $3.7 million during the three months ended March 31, 2018. There was no impact to our net income as a result of this change (See Note 1 to the Notes to Consolidated Financial Statements).

(A) The average asset balance for LSV for the three months ended March 31, 2017 was revised from $90.3 billion to $91.2 billion to include managed assets in which fees are based on performance only. The average value of these assets for the three months ended March 31, 2018 and 2017 was $2.3 billion and $1.7 billion, respectively.

In the preceding tables, assets under management are total assets of our clients or their customers invested in our equity and fixed-income investment programs, collective trust fund programs, and liquidity funds for which we provide asset management services through our subsidiaries and partnerships in which we have a significant interest. Advised assets include assets for which we provide advisory services through a subsidiary to the accounts but do not manage the underlying assets. Assets under administration include total assets of our clients or their customers for which we provide administrative services, including client fund balances for which we provide administration and/or distribution services through our subsidiaries and partnerships in which we have a significant interest. The assets presented in the preceding tables do not include assets processed on the SEI Wealth Platform and are not included in the accompanying Consolidated Balance Sheets because we do not own them.

•	The positive impact from foreign currency exchange rate fluctuations between the U.S. dollar and the British pound on our foreign operations; and


•	Increased investment processing fees earned on our mutual fund trading solution; partially offset by

•	Increased direct expenses associated with increased investment management fees from existing international clients;


•	Increased non-capitalized costs, mainly personnel and consulting costs, related to maintenance and support of the SEI Wealth Platform; and


•	Increased salary and incentive compensation costs.

Other

Other income and expense

Other income and expense items on the accompanying Consolidated Statements of Operations consists of:



	Three Months Ended March 31,
	2018			2017
Net (loss) gain from investments	$	(410	)	$	347
Interest and dividend income	2,502			1,343
Interest expense	(257		)	(112		)
Equity in earnings of unconsolidated affiliate	40,607			33,565
Total other income and expense items, net	$	42,442		$	35,143

Equity in earnings of unconsolidated affiliate

Equity in earnings of unconsolidated affiliate reflects our less than 50 percent ownership in LSV. As of March 31, 2018, our total partnership interest in LSV was 38.9 percent. The table below presents the revenues and net income of LSV and our proportionate share in LSV's earnings.



	Three Months Ended March 31,				Percent Change
	2018		2017		Percent Change
Revenues of LSV	$	131,718	$	109,953	20%
Net income of LSV	104,406		86,215		21%

SEI's proportionate share in earnings of LSV	$	40,607	$	33,565	21%

The increase in our earnings from LSV was primarily due to increased assets under management from LSV's existing clients due to market appreciation; however, our earnings were negatively impacted by increased personnel expenses of LSV. Average assets under management by LSV increased $18.8 billion to $109.9 billion during the three months ended March 31, 2018 as compared to $91.2 billion during the three months ended March 31, 2017, an increase of 21 percent.

Income Taxes

Our effective income tax rates for the three months ended March 31, 2018 and 2017 differs from the federal income tax statutory rate due to the following:



	Three Months Ended March 31,
	2018		2017
Statutory rate	21.0	%	35.0	%
State taxes, net of federal tax benefit	2.2		1.5
Foreign tax expense and tax rate differential	(0.2	)	(0.8	)
Tax benefit from stock option exercises	(10.8	)	(4.2	)
Other, net	(0.3	)	(0.5	)
	11.9	%	31.0	%

The decrease in our effective tax rate for the three months ended March 31, 2018 was primarily due to the tax changes enacted in The Tax Act. The Tax Act was enacted in December 2017 and included a permanent reduction in the corporate tax rate from 35.0 percent to 21.0 percent. In addition, our rate was favorably impacted by increased tax benefits due to a higher volume of stock option exercise activity during the first quarter of 2018 as compared to the first quarter of 2017.

Fair Value Measurements

The fair value of our financial assets and liabilities, except for the investment funds sponsored by LSV, is determined in accordance with the fair value hierarchy. The fair value of the investment funds sponsored by LSV is measured using the net asset value per share (NAV) as a practical expedient. The fair value of all other 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) and other U.S. government agency securities that are single issuer pools that are valued based on current market data of similar assets. We did not have any financial liabilities at March 31, 2018 or

30 of 38

December 31, 2017 that were required to be measured at fair value on a recurring basis (See Note 5 to the Notes to Consolidated Financial Statements).

Regulatory Matters

Like many firms operating within the financial services industry, we are experiencing a difficult regulatory environment across our markets. Our current scale and reach as a provider to the financial services industry, the introduction and implementation of new platforms for our financial services industry clients, the increased regulatory oversight of the financial services industry generally, new laws and regulations affecting the financial services industry and ever-changing regulatory interpretations of existing laws and regulations, and a greater propensity of regulators to pursue enforcement actions and other sanctions against regulated entities, have made this an increasingly challenging and costly regulatory environment in which to operate.

SEI and some of our regulated subsidiaries have undergone or been scheduled to undergo a range of periodic or thematic reviews, examinations or investigations by numerous regulatory authorities around the world, including the Office of the Comptroller of the Currency, the Securities and Exchange Commission, the Financial Industry Regulatory Authority, Inc., the Financial Conduct Authority of the United Kingdom, the Central Bank of Ireland and others. These regulatory activities typically result in the identification of matters or practices to be addressed by us or our subsidiaries and, in certain circumstances, the regulatory authorities require remediation activities or pursue enforcement proceedings against us or our subsidiaries. As described under the caption “Regulatory Considerations” in our Annual Report on Form 10-K, the range of possible sanctions that are available to regulatory authorities include limitations on our ability to engage in business for specified periods of time, the revocation of registration, censures and fines. The direct and indirect costs of responding to these regulatory activities and of complying with new or modified regulations, as well as the potential financial costs and potential reputational impact against us of any enforcement proceedings that might result, is uncertain but could have a material adverse impact on our operating results or financial position.

Liquidity and Capital Resources



	Three Months Ended March 31,
	2018			2017
Net cash provided by operating activities	$	104,174		$	73,012
Net cash used in investing activities	(15,376		)	(25,345		)
Net cash used in financing activities	(87,285		)	(84,303		)
Effect of exchange rate changes on cash, cash equivalents and restricted cash	2,541			2,307
Net increase (decrease) in cash, cash equivalents and restricted cash	4,054			(34,329		)
Cash, cash equivalents and restricted cash, beginning of period	747,752			699,201
Cash, cash equivalents and restricted cash, end of period	$	751,806		$	664,872

Cash requirements and liquidity needs are primarily funded through our cash flow from operations and our capacity for additional borrowing. At March 31, 2018, our unused sources of liquidity consisted of cash and cash equivalents and the amount available under our credit facility. We adopted ASU No. 2016-18, Statement of Cash Flows, Restricted Cash (Topic 230) (ASU 2016-18) on January 1, 2018 which requires the statement of cash flows to explain the change during the period for the total of cash, cash equivalents, and amounts generally described as restricted cash or restricted cash equivalents. The prior period was retrospectively adjusted to conform to the current period’s presentation. There was no impact to net cash flows for the three months ended March 31, 2017 as a result of including restricted cash with cash and cash equivalents.

Our credit facility provides for borrowings of up to $300.0 million and is scheduled to expire in June 2021 (See Note 7 to the Consolidated Financial Statements). The availability of the credit facility is subject to compliance with certain covenants set forth in the agreement. The credit facility contains covenants which restrict our ability 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, we would also be restricted from paying dividends on, or repurchasing, our common stock. Currently, our ability to borrow from the credit facility is not limited by any covenant of the agreement. In July 2017, we borrowed $40.0 million under the credit facility for the funding of an acquisition. We made a principal payment of $20.0 million during April 2018 to fully repay the outstanding balance of the facility. As of April 19, 2018, the full amount of $300.0 million of the credit facility was available for corporate purposes.

The majority of our excess cash reserves are primarily placed in accounts located in the United States that invest entirely in SEI-sponsored money market mutual funds denominated in the U.S. dollar. We also utilize demand deposit accounts or money market accounts at several well-established financial institutions located in the United States. Accounts used to manage these

31 of 38

excess cash reserves do not impose any restrictions or limitations that would prevent us from being able to access such cash amounts immediately. As of April 19, 2018, the amount of cash and cash equivalents considered free and immediately accessible for other general corporate purposes was $315.9 million.

Our cash and cash equivalents include accounts managed by our 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. We therefore do not include accounts of our foreign subsidiaries in our calculation of free and immediately accessible cash for other general corporate purposes. With the enactment of the Tax Act, a portion of the undistributed earnings of our foreign subsidiaries are deemed repatriated. Any subsequent transfer of available cash related to the repatriated earnings of our foreign subsidiaries could significantly increase our free and immediately accessible cash.

Cash flows from operations increased $31.2 million in the first three months of 2018 compared to the first three months of 2017 primarily from the increase in our net income and higher distribution payments received from our unconsolidated affiliate, LSV. The increase was partially offset by the negative impact from the change in our working capital accounts.

Net cash used in investing activities includes:

•Purchases, sales and maturities of marketable securities. Our purchases, sales and maturities of marketable securities in the first three months of 2018 and 2017 were as follows:



	Three Months Ended March 31,
	2018			2017
Purchases	$	(15,466	)	$	(20,445	)
Sales and maturities	18,588			15,166
Net investing activities from marketable securities	$	3,122		$	(5,279	)


•	The capitalization of costs incurred in developing computer software. We capitalized $12.9 million of software development costs in the first three months of 2018 as compared to $16.9 million in the first three months of 2017. The majority of our software development costs are related to significant enhancements for the expanded functionality of the SEI Wealth Platform.


•	Capital expenditures. Our capital expenditures in the first three months of 2018 were $5.6 million as compared to $3.2 million in the first three months of 2017. Our expenditures in 2018 and 2017 primarily include purchased software, equipment for our data center operations and the expansion of our corporate headquarters.

Net cash used in financing activities includes:


•	Principal repayments on revolving credit facility. In July 2017, we borrowed $40.0 million for the funding of an acquisition. We made principal payments of $10.0 million each during October 2017 and January 2018 and a final payment of $20.0 million during April 2018 to repay the entire outstanding balance (See Note 7 to the Consolidated Financial Statements).

•

The repurchase of our common stock. Our Board of Directors has authorized the repurchase of our common stock through multiple authorizations. Currently, there is no expiration date for our common stock repurchase program. We had total capital outlays of $88.0 million during the first three months of 2018 and $56.6 million during the first three months of 2017 for the repurchase of our common stock.


•	Proceeds from the issuance of our common stock. We received $57.9 million in proceeds from the issuance of our common stock during the first three months of 2018 as compared to $16.8 million during the first three months of 2017. The increase in proceeds is primarily attributable to a higher level of stock option exercise activity.


•	Dividend payments. Cash dividends paid were $47.2 million in the first three months of 2018 as compared to $44.6 million in the first three months of 2017.

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 and future dividend payments.

32 of 38

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;


•	risk of failure by a third-party service provider;


•	data and cyber security risks;


•	operational risks associated with the processing of investment transactions;


•	systems and technology risks;


•	pricing pressure from increased competition, disruptive technology and poor investment performance;


•	the affect on our earnings and cashflows from the performance of LSV Asset Management;


•	third party pricing services for the valuation of securities invested in our investment products;


•	the affect of extensive governmental regulation;


•	litigation and regulatory examinations and investigations;


•	increased costs and regulatory risks from the growth of our business;


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


•	the exit by the United Kingdom from the European Union;


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


•	financial and non-financial covenants which may restrict our ability to manage liquidity needs;


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


•	fluctuations in foreign currency exchange rates;


•	fluctuations in interest rates affecting the value of our fixed-income investment securities; and


•	retention of executive officers and senior management personnel.

Our regulated wholly-owned subsidiaries include SEI Investments Distribution Co., or SIDCO, SEI Investments Management Corporation, or SIMC, SEI Private Trust Company, or SPTC, SEI Trust Company, or STC, and SEI Investments (Europe) Limited, or SIEL, SEI Investments Canada Company, or SEI Canada, SEI Investments Global, Limited, or SIGL, SEI Investments - Global Fund Services, Ltd., or GFSL, and SEI Investments - Depositary and Custodial Services (Ireland) Limited, or D&C. SIDCO is a broker-dealer registered with the SEC under the Securities Exchange Act of 1934 and is a member of the Financial Industry Regulatory Authority, Inc. (FINRA). SIMC is an investment advisor registered with the SEC under the Investment Advisers Act of 1940 and with the Commodity Futures Trading Commission (CFTC) under the Commodity Exchange Act. SPTC is a limited purpose federal thrift chartered and regulated by the Office of the Comptroller of the Currency. STC is a Pennsylvania trust company, regulated by the Pennsylvania Department of Banking and Securities. SIEL is an investment manager and financial institution subject to regulation by the Financial Conduct Authority of the United Kingdom. SEI Canada is regulated by the Ontario Securities Commission and various provincial authorities as an investment fund manager and in various other capacities. SIGL is primarily regulated by the Central Bank of Ireland (CBI) as a management company for Undertakings for Collective Investment in Transferable Securities, or UCITS, and for Alternative Investment Funds, or AIFs. GFSL is regulated by the CBI and authorized to provide administration services for Irish and non-Irish collective investment schemes. D&C is regulated by the CBI and authorized to provide depositary and custodial services. In addition, various SEI subsidiaries are subject to the jurisdiction of regulatory authorities in other foreign countries. The Company has a minority ownership interest in LSV, which is also an investment advisor registered with the SEC.

The Company, its regulated subsidiaries, their regulated services and platforms and their customers are all subject to extensive legislation, regulation and supervision that recently has been subject to, and continues to experience, significant change and increased regulatory activity. These changes and regulatory activities could have a material adverse effect on us and our clients.

The various governmental agencies and self-regulatory authorities that regulate or supervise the Company and its subsidiaries have broad administrative powers. In the event of a failure to comply with laws, regulations and requirements of these agencies and authorities, the possible sanctions that may be imposed include the suspension of individual employees, limitations on our ability to engage in business for specified periods of time, the revocation of applicable registration as a broker-dealer, investment advisor or other regulated entity, and, as the case may be, censures and fines. Additionally, certain securities and banking laws applicable to us and our subsidiaries provide for certain private rights of action that could give rise to civil

33 of 38

litigation. Any litigation could have significant financial and non-financial consequences including monetary judgments and the requirement to take action or limit activities that could ultimately affect our business.

Governmental scrutiny from regulators, legislative bodies and law enforcement agencies with respect to matters relating to our regulated subsidiaries and their activities, services and platforms, our business practices, our past actions and other matters has increased dramatically in the past several years. Responding to these examinations, investigations, actions and lawsuits, regardless of the ultimate outcome of the proceeding, is time consuming and expensive and can divert the time and effort of our senior management from our business. Penalties and fines sought by regulatory authorities have increased substantially over the last several years, and certain regulators have been more likely in recent years to commence enforcement actions or to advance or support legislation targeted at the financial services industry. We continue to be subject to inquiries from examinations and investigations by supervisory and enforcement divisions of regulatory authorities and expect this to continue in the future. We believe this is also the case with many of our regulated clients. Governmental scrutiny and legal and enforcement proceedings can also have a negative impact on our reputation, our relationship with clients and prospective clients, and on the morale and performance of our employees, which could adversely affect our businesses and results of operations.

We are subject to the USA PATRIOT Act of 2001, which contains anti-money laundering and financial transparency laws and requires implementation of regulations applicable to financial services companies, including standards for verifying client identification and monitoring client transactions and detecting and reporting suspicious activities. Anti-money laundering laws outside the United States contain similar requirements. We offer investment and banking platforms that also are subject to regulation by the federal and state securities and banking authorities, as well as foreign regulatory authorities, where applicable. Existing or future regulations that affect these platforms could lead to a reduction in sales of these platforms or require modifications of these platforms.

Compliance with existing and future regulations and responding to and complying with recent increased regulatory activity affecting broker-dealers, investment advisors, investment companies, financial institutions and their service providers could have a significant impact on us. We periodically undergo regulatory examinations and respond to regulatory inquiries and document requests. In addition, recent and continuing legislative activity in the United States and in other jurisdictions (including the European Union and the United Kingdom) have made and continue to make extensive changes to the laws regulating financial services firms. Recent changes include the effectiveness of the Markets in Financial Instruments Directive (MiFID II) and pending effectiveness of the General Data Protection Regulation in the European Union and the U.S. Department of Labor's Fiduciary Rule. As a result of these examinations, inquiries and requests, as a result of increased civil litigation activity, and as a result of these new laws and regulations, we engage legal counsel, review our compliance procedures, platform and service offerings, and business operations, and make changes as we deem necessary. These additional activities and required changes may result in increased expense or may reduce revenues.

Our bank clients are subject to supervision by federal, state and foreign banking and financial services authorities concerning the manner in which such clients purchase and receive our products and services. Our plan sponsor clients and our subsidiaries 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, state securities authorities, or FINRA. 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 required by this item is set forth under the captions "Our revenues and earnings are affected by changes in capital markets" and "Changes in interest rates may affect the value of our fixed-income investment securities" in Item 1A "Risk Factors" and under the caption "Sensitivity of our revenues and earnings to capital market fluctuations" in Item 7 "Management's Discussion and Analysis of Financial Condition and Results of Operations" of our Annual Report on Form 10-K for the year ended December 31, 2017. There have been no material changes to this information as it is disclosed in our Annual Report on Form 10-K for 2017.

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

34 of 38

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 March 31, 2018 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.

SEI has been named in seven lawsuits filed in Louisiana courts; four of the cases also name SPTC as a defendant. The underlying allegations in all actions relate to the purported role of SPTC in providing back-office services to Stanford Trust Company. The complaints allege that SEI and SPTC participated in some manner in the sale of “certificates of deposit” issued by Stanford International Bank so as to be a “seller” of the certificates of deposit for purposes of primary liability under the Louisiana Securities Law or so as to be secondarily liable under that statute for sales of certificates of deposit made by Stanford Trust Company. Two of the actions also include claims for violations of the Louisiana Racketeering Act and possibly conspiracy, and a third also asserts claims of negligence, breach of contract, breach of fiduciary duty, violations of the uniform fiduciaries law, negligent misrepresentation, detrimental reliance, violations of the Louisiana Racketeering Act, and conspiracy.

The plaintiffs in two of the cases remaining in the Parish of East Baton Rouge have granted SEI and SPTC indefinite extensions to respond to the petitions.

First-Quarter Business Highlights:


•	Revenue growth in the quarter was primarily driven by higher Asset management, administration, and distribution fees from market appreciation and positive cash flows from new and existing clients.


•	Information processing and software servicing fees in our Private Banks segment increased $6.4 million in first-quarter 2018 compared to first-quarter 2017 primarily due to increased assets from new and existing clients processed on the SEI Wealth Platform^SM(the Platform).


•	Revenues from the SEI Archway acquisition were $5.5 million during the first-quarter 2018. SEI Archway was acquired during the third-quarter 2017 and is reported in our Investment Managers segment.


•	Our average assets under management, excluding LSV, increased $32.2 billion, or 16 percent, to $233.6 billion, as compared to $201.4 billion during the first-quarter 2017 (see attached Average Asset Balances schedules for further details).


•	Our average assets under administration increased $56.4 billion, or 12 percent, to $530.3 billion in the first-quarter 2018, as compared to $474.0 billion during the first-quarter 2017 (see attached Average Asset Balances schedules for further details).


•	Sales events, net of client losses, during first-quarter 2018 totaled approximately $18.8 million and are expected to generate net annualized recurring revenues of approximately $11.6 million when contract values are fully realized.


•	Our earnings from LSV increased by $7.0 million, or 21 percent, to $40.6 million in first-quarter 2018 as compared to $33.6 million in first-quarter 2017. The increase in earnings was due to an increase in assets under management from market appreciation; however, our earnings were negatively impacted by increased personnel expenses of LSV.

•

Our operating expenses, primarily personnel costs, in our Investment Advisors and Investment Managers segments increased. These expenses primarily consist of operational, technology and marketing costs and are mainly related to servicing existing clients and acquiring new clients. In addition, our Investment Managers segment includes personnel costs related to SEI Archway acquired during the third-quarter 2017.

•

We capitalized $12.9 million and $16.9 million of software development costs in first-quarter 2018 and 2017, respectively, of which $12.0 million and $15.2 million are related to continued enhancements to the Platform. Our expenses related to maintenance and enhancements not eligible for capitalization have increased. A higher portion of these costs are recognized in personnel and consulting costs. These increased costs primarily impacted the Private Banks and Investment Advisors business segments.


•	Amortization expense related to the Platform decreased to $9.7 million during the first-quarter 2018 as compared to $12.0 million during the first-quarter 2017 due to an adjustment to the estimated useful life of the Platform effective in the fourth-quarter 2017.


•	During the first-quarter 2018, we placed into service an application developed for the Investment Managers segment. This new offering includes components that leverage upon the current infrastructure and add significant enhancements designed to aggregate, transact and process data. Amortization expense related to the application was $1.3 million during first-quarter 2018.


•	Our effective tax rate was 11.9 percent in first-quarter 2018 as compared to 31.0 percent in first-quarter 2017. The decline in our tax rate was primarily due to the tax changes enacted in the Tax Cuts and Jobs Act in December 2017 and increased tax benefits due to a higher volume of stock option exercise activity.

•

We adopted ASU Accounting Standards Update No. 2014-09, Revenue from Contracts with Customers (ASU 2014-09) on January 1, 2018. With our adoption of ASU 2014-09, fees received for research services provided by our brokerage subsidiary, SIDCO, are now recorded net of amounts paid for the soft dollar arrangement. As a result, our revenues and expenses in first-quarter 2018 were each reduced by $3.7 million with no impact to net income. Refer to our

first-quarter 2018 Form 10-Q for information regarding the impact of ASU 2014-09 on our financial statements.


•	We repurchased 1.1 million shares of our common stock for $82.3 million during the first-quarter 2018.
