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 consist of outsourcing services including fund and investment accounting, administration, reconciliation, investor servicing and client reporting. 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 September 30, 2019, the results of operations for the three and nine months ended September 30, 2019 and 2018, and cash flows for the nine-month periods ended September 30, 2019 and 2018. 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, 2018.

The Company adopted the requirements of the Accounting Standards Update (ASU) No. 2016-2 Leases (Topic 842) (Accounting Standards Codifications (ASC) 842 (ASC 842)) using the modified retrospective method during the nine months ended September 30, 2019. As a result of the adoption of ASC 842, the Company recorded additional lease assets and net lease liabilities of $44,169 as of January 1, 2019. Upon implementation, the Company elected the package of practical expedients permitted under the transition guidance within the new standard which allowed the Company to carryforward the historical lease identification, classification and initial direct cost. ASC 842 did not materially impact the Company’s consolidated net income or consolidated cash flows (see following caption "Leases"). With the exception of the adoption of ASC 842, there have been no significant changes in significant accounting policies during the nine months ended September 30, 2019 as compared to the significant accounting policies described in the Company's Annual Report on Form 10-K for the year ended December 31, 2018.

Variable Interest Entities

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

Page 9 of 48

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 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 $6,390 and $6,525 in fees during the three months ended September 30, 2019 and 2018, respectively. During the nine months ended September 30, 2019 and 2018, the Company waived $21,091 and $19,551, respectively, in fees.

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).

Cash and Cash Equivalents

Cash and cash equivalents includes $319,977 and $315,840 at September 30, 2019 and December 31, 2018, 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 September 30, 2019 and December 31, 2018 segregated for regulatory purposes related to trade-execution services conducted by SEI Investments (Europe) Limited. Restricted cash also includes $100 and $514 at September 30, 2019 and December 31, 2018, 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 $26,821 and $33,371 of software development costs during the nine months ended September 30, 2019 and 2018, respectively. The Company's software development costs primarily relate to significant enhancements to the SEI Wealth Platform^SM (SWP). The Company capitalized $26,029 and $32,526 of software development costs for significant enhancements to SWP during the nine months ended September 30, 2019 and 2018, respectively. As of September 30, 2019, the net book value of SWP was $283,128. The net book value includes $51,781 of capitalized software development costs in-progress associated with future releases. Capitalized software development costs in-progress associated with future releases of SWP were $42,238 as of December 31, 2018. SWP has a weighted average remaining life of 8.4 years. Amortization expense for SWP was $31,567 and $29,723 during the nine months ended September 30, 2019 and 2018, respectively.

Earnings per Share

The calculations of basic and diluted earnings per share for the three and nine months ended September 30, 2019 and 2018 are:

	Three Months Ended September 30,				Nine Months Ended September 30,
	2019		2018		2019		2018
Net income	$	132,168	$	128,319	$	372,689	$	389,834
Shares used to compute basic earnings per common share	150,855,000		156,283,000		152,009,000		157,086,000
Dilutive effect of stock options	3,372,000		4,228,000		3,302,000		4,967,000
Shares used to compute diluted earnings per common share	154,227,000		160,511,000		155,311,000		162,053,000
Basic earnings per common share	$	0.88	$	0.82	$	2.45	$	2.48
Diluted earnings per common share	$	0.86	$	0.80	$	2.40	$	2.41

Page 10 of 48

During the three months ended September 30, 2019 and 2018, employee stock options to purchase 6,239,000 and 6,183,000 shares of common stock with an average exercise price of $54.91 and $53.38, respectively, were outstanding but not included in the computation of diluted earnings per common share. During the nine months ended September 30, 2019 and 2018, employee stock options to purchase 6,269,000 and 6,153,000 shares of common stock with an average exercise price of $54.84 and $53.15, respectively, were outstanding but not included in the computation of diluted earnings per common share. These options for the three and nine 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 not have been satisfied if the reporting date was the end of the contingency period or the options' 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.

Leases

The Company determines if an arrangement is a lease at the inception of the contract. The Company's operating leases are included in Operating lease right-of-use (ROU) assets, Current portion of long-term operating lease liabilities, and Long-term operating lease liabilities on the accompanying Consolidated Balance Sheet.

The operating lease ROU assets and operating lease liabilities are recognized based on the present value of future minimum lease payments over the lease term at commencement date. As most of the Company’s leases do not provide an implicit interest rate, the Company utilizes an estimated incremental borrowing rate based on the information available at commencement date in determining the present value of future payments. In determining the discount rate used in the present value calculation, the Company has elected to apply the portfolio approach for leases of equipment provided the leases commenced at or around the same time. This election allows the Company to account for leases at a portfolio level provided that the resulting accounting at this level would not differ materially from the accounting at the individual lease level. Lease expense for minimum lease payments is recognized on a straight-line basis over the lease term.

The Company has elected to account for lease and non-lease components separately. Operating lease ROU assets include all contractual lease payments and initial direct costs incurred, less any lease incentives. Facility leases generally only contain lease expense and non-component items such as taxes and pass through charges. Only the lease components are included in the ROU assets and lease liabilities. Additionally, the Company has elected not to apply the recognition requirements of ASC 842 to leases which have a lease term of less than one year at the commencement date.

The majority of the Company's leases for corporate facilities and equipment contain terms for renewal and extension of the lease agreement. The exercise of lease renewal options is generally at the Company’s sole discretion. The Company includes the lease extensions when it is reasonably certain the Company will exercise the extension. The Company’s lease agreements do not contain any material variable lease payments, material residual value guarantees or any material restrictive covenants. The Company does not currently have any finance leases.

See Note 15 for information on related disclosures regarding leases.

New Accounting Pronouncements

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) and a subsequent amendment ASU 2019-04, Codification Improvements to Topic 326, Financial Instruments-Credit Losses, Topic 815, Derivatives and Hedging, and Topic 825, Financial Instruments (ASU 2019-04) in April 2019. ASU 2016-13 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 2019-04 provides certain improvements to ASU 2016-13. ASU 2016-13 and ASU 2019-04 become effective for the Company during the first quarter of 2020. Early adoption is permitted. The Company is currently finalizing its evaluation of ASU 2016-13 and ASU 2019-04 and does not believe the adoption of the updated standards will have a material impact 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 does not believe the adoption of ASU 2017-04 will have a material impact on its consolidated financial statements and related disclosures.

In August 2018, the FASB issued ASU 2018-13, Fair Value Measurement (Topic 820): Disclosure Framework - Changes to the Disclosure Requirements for Fair Value Measurement (ASU 2018-13) which modifies the disclosure requirements

Page 11 of 48

on fair value measurements. ASU 2018-13 is effective for the Company beginning in the first quarter of 2020. The Company is currently finalizing its evaluation of ASU 2018-13 and does not believe the adoption of the updated standard will have a material impact on its consolidated financial statements and related disclosures.

In October 2018, the FASB issued ASU 2018-17, Consolidation (Topic 810): Targeted Improvements to Related Party Guidance for Variable Interest Entities (ASU 2018-17). The new standard changes how entities evaluate decision-making fees under the variable interest entity guidance. ASU 2018-17 is effective for the Company beginning in the first quarter of 2020. The Company does not believe the adoption of ASU 2018-17 will have a material impact on its consolidated financial statements and related disclosures.

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's partnership interest in LSV as of September 30, 2019 was 38.9%. The Company accounts for its interest in LSV using the equity

Page 12 of 48

method because of its less than 50% 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 September 30, 2019, the Company’s total investment in LSV was $41,437. The Company receives partnership distributions from LSV on a quarterly basis. The Company received partnership distributions from LSV of $123,663 and $138,216 in the nine months ended September 30, 2019 and 2018, 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 $37,609 and $41,726 during the three months ended September 30, 2019 and 2018, respectively. During the nine months ended September 30, 2019 and 2018, the Company’s proportionate share in the earnings of LSV was $112,758 and $123,406, respectively.

These tables contain condensed financial information of LSV:

Fees earned, not billed represents receivables from contracts with customers earned but unbilled and results from timing differences between services provided and contractual billing schedules. These billing schedules generally provide for fees to be billed on a quarterly basis. In addition, certain fees earned from investment operations services are calculated based on assets under administration that have an extended valuation process. Billings to these clients occur once the asset valuation processes are completed.

Receivables from investment products on the accompanying Consolidated Balance Sheets primarily represent fees receivable for distribution, investment advisory, and administration services to various regulated investment companies and other investment products sponsored by SEI.

Note 4.    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 2023 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

Page 14 of 48

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.

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 nine months ended September 30, 2019 were consistent with those as described in our Annual Report on Form 10-K at December 31, 2018. The Company had no Level 3 financial assets at September 30, 2019 or December 31, 2018 that were required to be measured at fair value on a recurring basis. The Company's Level 3 financial liabilities at September 30, 2019 and December 31, 2018 consist entirely of the estimated contingent consideration resulting from an acquisition (See Note 12). The fair value of the contingent consideration was determined using a Monte-Carlo simulation model. Key assumptions for the Monte-Carlo simulation model include expected revenues, expected volatility, risk-free rate and correlation coefficient. There were no transfers of financial assets between levels within the fair value hierarchy during the nine months ended September 30, 2019.

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	September 30, 2019		Quoted Prices in Active  Markets for Identical Assets (Level 1)		Significant Other Observable Inputs (Level 2)

Net unrealized gains at September 30, 2019 of the Company's available-for-sale debt securities were $494 (net of income tax expense of $148). Net unrealized losses at December 31, 2018 of the Company's available-for-sale debt securities were $1,413 (net of income tax benefit of $422). These net unrealized gains and losses are reported as a separate component of Accumulated other comprehensive loss on the accompanying Consolidated Balance Sheets.

There were gross realized gains of $1,031 and gross realized losses of $1,520 during the nine months ended September 30, 2018. Gross realized gains and losses from available-for-sale securities during the nine months ended September 30, 2019 were immaterial. Gains and losses from available-for-sale securities, including amounts reclassified from accumulated comprehensive loss, are reflected in Net gain (loss) 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 gain (loss) 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 $5,533 and $4,887 at September 30, 2019 and December 31, 2018, respectively. The Company recognized gains of $646 and losses of $298 during the nine months ended September 30, 2019 and 2018, respectively, from the change in fair value of the funds. There were no material gains or losses during the three months ended September 30, 2019 and 2018 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 $32,862 and $30,892 at September 30, 2019 and December 31, 2018, respectively. There were no material net gains or losses related to the securities during the three and nine months ended September 30, 2019 and 2018.

Note 6.    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

Page 16 of 48

can range from 0.25% to 1.00% or the London InterBank Offered Rate (LIBOR) plus a premium that can range from 1.25% to 2.00% 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%, b) the prime commercial lending rate of Wells Fargo, c) the applicable LIBOR plus 1.00%, or d) 0%. 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% of the amount of the unused portion to 0.30%, 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. The Company may issue up to $15,000 in letters of credit under the terms of the Credit Facility. The Company pays a periodic commission fee of 1.25% plus a fronting fee of 0.175% of the aggregate face amount of the outstanding letters of credit issued under the Credit Facility.

The Credit Facility contains covenants that restrict the ability of the Company to engage in mergers, consolidations, asset sales, investments, transactions with affiliates other than wholly-owned subsidiaries, or to incur liens or other indebtedness including contingent obligations or guarantees, 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. 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.

As of September 30, 2019, the Company had outstanding letters of credit of $11,553 under the Credit Facility. These letters of credit were issued primarily for the expansion of the Company's headquarters and are scheduled to expire during the remainder of 2019. The amount of the Credit Facility that is available for general corporate purposes as of September 30, 2019 was $288,447.

The Company was in compliance with all covenants of the Credit Facility during the nine months ended September 30, 2019.

Note 7.    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% when a specified diluted earnings per share target is achieved, and the remaining 50% 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 and thereafter 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 and nine months ended September 30, 2019 and 2018, respectively, as follows: 

	Three Months Ended September 30,						Nine Months Ended September 30,
	2019			2018			2019			2018
Stock-based compensation expense	$	5,453		$	5,878		$	15,555		$	16,396
Less: Deferred tax benefit	(1,042		)	(1,311		)	(2,959		)	(3,556		)
Stock-based compensation expense, net of tax	$	4,411		$	4,567		$	12,596		$	12,840

As of September 30, 2019, there was approximately $50,330 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 nine months ended September 30, 2019 was $43,246. The total options exercisable as of September 30, 2019 had an intrinsic value of $197,860. The total intrinsic value for options exercisable is calculated as

Page 17 of 48

the difference between the market value of the Company’s common stock as of September 30, 2019 and the weighted average exercise price of the options. The market value of the Company’s common stock as of September 30, 2019 was $59.26 as reported by the Nasdaq Stock Market, LLC. The weighted average exercise price of the options exercisable as of September 30, 2019 was $25.08. Total options that were outstanding as of September 30, 2019 were 14,132,000. Total options that were exercisable as of September 30, 2019 were 7,890,000.

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 4,950,000 shares at a total cost of $267,184 during the nine months ended September 30, 2019, 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 September 30, 2019, the Company had approximately $198,695 of authorization remaining for the purchase of common stock under the program.

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

Cash Dividend

On May 29, 2019, the Board of Directors declared a cash dividend of $0.33 per share on the Company's common stock, which was paid on June 20, 2019, to shareholders of record on June 12, 2019. Cash dividends declared during the nine months ended September 30, 2019 and 2018 were $49,984 and $47,139, respectively.

Note 10.    Income Taxes

The gross liability for unrecognized tax benefits at September 30, 2019 and December 31, 2018 was $14,627 and $14,367, respectively, exclusive of interest and penalties, of which $14,183 and $13,774 would affect the effective tax rate if the Company were to recognize the tax benefit.

The Company classifies interest and penalties on unrecognized tax benefits as income tax expense. As of September 30, 2019 and December 31, 2018, the combined amount of accrued interest and penalties related to tax positions taken on tax returns was $1,520 and $1,289, respectively.

	September 30, 2019		December 31, 2018
Gross liability for unrecognized tax benefits, exclusive of interest and penalties	$	14,627	$	14,367
Interest and penalties on unrecognized benefits	1,520		1,289
Total gross uncertain tax positions	$	16,147	$	15,656
Amount included in Current liabilities	$	1,008	$	3,131
Amount included in Other long-term liabilities	15,139		12,525
	$	16,147	$	15,656

The Company's effective income tax rate for the three and nine months ended September 30, 2019 and 2018 differs from the federal income tax statutory rate due to the following:

	Three Months Ended September 30,				Nine Months Ended September 30,
	2019		2018		2019		2018
Statutory rate	21.0	%	21.0	%	21.0	%	21.0	%
State taxes, net of federal tax benefit	2.6		2.3		2.6		2.3
Foreign tax expense and tax rate differential	(0.3	)	(0.2	)	(0.2	)	(0.2	)
Tax benefit from stock option exercises	(2.2	)	(1.4	)	(1.5	)	(4.8	)
Expiration of the statute of limitations	(1.2	)	(1.0	)	(0.4	)	(0.3	)
Provision-to-return adjustment	(0.6	)	(2.3	)	(0.2	)	(0.8	)
Other, net	(0.4	)	0.2		(0.3	)	—
	18.9	%	18.6	%	21.0	%	17.2	%

The increase in the Company's effective tax rate for the nine months ended September 30, 2019 was primarily due to reduced tax benefits related to the lower volume of stock option exercises as compared to the nine months ended September 30, 2018.

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 2015 and is no longer subject to state, local or foreign income tax examinations by authorities for years before 2014.

The Company estimates it will recognize $1,008 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

Page 21 of 48

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 11.    Commitments and Contingencies

In the ordinary course of business, the Company from time to time enters into contracts containing indemnification obligations of the Company. These obligations may require the Company to make payments to another party upon the occurrence of certain events including the failure by the Company to meet its performance obligations under the contract. These contractual indemnification provisions are often standard contractual terms of the nature customarily found in the type of contracts entered into by the Company. In many cases, there are no stated or notional amounts included in the indemnification provisions. There are no amounts reflected on the Consolidated Balance Sheets as of September 30, 2019 and December 31, 2018 related to these indemnifications.

Stanford Trust Company Litigation

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 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 remaining 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 (“Ahders Complaint”), alleging claims essentially the same as those in Lillie. In January 2017, the Judicial Panel on Multidistrict Litigation transferred the Ahders proceeding to the Northern District of Texas and the Stanford MDL. During February 2017, SEI filed its response to the Ahders 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. In both cases, as a result of the proceedings in the Northern District of Texas, only the plaintiffs’ secondary liability claims under Section 714(B) of the Louisiana Securities Law remain. Limited discovery and motions practice have occurred, including SEI and SPTC’s filing of a dispositive summary judgment motion in the Lillie proceeding. On January 31, 2019, the Judicial Panel on Multidistrict Litigation remanded the Lillie and Ahders proceedings to the Middle District of Louisiana.

On July 9, 2019, the District Court issued an order granting SEI’s Summary Judgment Motion to dismiss the remaining Section 714(B) claim in the Lillie proceeding and denying Plaintiffs’ Motion for Continuance of SEI and SPTC’s Motion for Summary Judgment pursuant to Rule 56(d).

Page 22 of 48

On July 16, 2019, SEI and SPTC filed a Motion for Summary Judgment pursuant to Rule 56(d) in the Ahders proceeding to have the remaining Section 714(B) claim dismissed.

On July 17, 2019, Plaintiffs filed a Motion for Reconsideration and/or New Trial as to the July 9, 2019 Ruling and Order (ECF 146) by the Honorable Brian A. Jackson denying a continuance of SEI’s Motion for Summary Judgment pursuant to Rule 56(d). The Court denied Plaintiffs’ Motion and entered a Final Judgment in favor of SEI on August 15, 2019.

On August 27, 2019, Plaintiffs filed a Notice of Appeal to the United States Court of Appeal for the Fifth Circuit of the District Court's dismissal of the matter. Plaintiffs’ Motion in Support of the Notice of Appeal must be filed with the Court by November 20, 2019. If Plaintiffs’ Motion in Support of Appeal is filed, SEI intends to contest the Plaintiffs' appeal.

Another case, 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.

Two additional cases remain in the Parish of East Baton Rouge. Plaintiffs filed petitions in 2010 and have granted SEI and SPTC indefinite extensions to respond. No material activity has taken place since.

In 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 subject matter jurisdiction under the federal Securities Litigation Uniform Standards Act (SLUSA). The matters were removed to the United States District Court for the Northern District of Texas and consolidated. The court then 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 matters were 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.

SEI Capital Accumulation Plan Litigation

On September 28, 2018, a class action complaint was filed in the United States District Court for the Eastern District of Pennsylvania by Gordon Stevens, individually and as the representative of similarly situated persons, and on behalf of the SEI Capital Accumulation Plan (the “Plan”) naming the Company and its affiliated and/or related entities SEI Investments Management Corporation, SEI Capital Accumulation Plan Design Committee, SEI Capital Accumulation Plan Investment Committee, SEI Capital Accumulation Plan Administration Committee, and John Does 1-30 as defendants (the “Stevens Complaint”). The Stevens Compliant seeks unspecified damages for defendants’ breach of fiduciary duties under ERISA with respect to selecting and monitoring the Plan’s investment options and by retaining affiliated investment products in the Plan.

Although SEI believes its defenses against the plaintiff’s allegations were valid, the Company agreed to settle this matter in the very early stages of the litigation in order to avoid the high cost of protracted class-action litigation and internal distractions such cases bring. The written settlement agreement was submitted to the Court on July 26, 2019, and is a matter of public record. A Preliminary Approval Order approving the settlement agreement was issued by the Court and the Court has scheduled a fairness hearing for December 18, 2019. The settlement agreement will not be finalized until the Court has issued a final approval after the December 18, 2019. The Company expects final Court approval of the settlement by year-end. The Company expects the financial impact of the settlement agreement to be immaterial.

Other Matters

The Company is also a party to various other actions and claims arising in the normal course of business that the Company does not believe are material. The Company believes that the ultimate resolution of these matters will not have a material adverse effect on the Company's financial position or the manner in which the Company conducts its business. Currently, the Company does not believe the amount of losses associated with these matters can be estimated. While the Company does not believe that the amount of such losses will, when liquidated or estimable, be material to its financial position, the assumptions may be incorrect and any such loss could have a material adverse effect on the Company's results of operations or the manner in which the Company conducts its business in the period(s) during which the underlying matters are resolved.

Note 12.    Business Acquisition

On April 2, 2018, the Company acquired all ownership interests of Huntington Steele, LLC (Huntington Steele), a registered investment advisor based in Seattle, Washington servicing the ultra-high-net-worth market. The total purchase price for Huntington Steele was $17,914, which includes $5,794 in cash consideration, net of $125 in cash acquired, and a contingent purchase price of $12,120. The contingent purchase price consists of amounts payable to the sellers upon the attainment of specified financial measures determined at various intervals occurring between 2019 and 2023. The Company made a payment of $433 to the sellers during the nine months ended September 30, 2019. As of September 30, 2019, the current portion of the contingent purchase price of $535 is included in Accrued liabilities on the accompanying Balance Sheet. The long-term portion of the contingent consideration of $11,152 is included in Other long-term liabilities on the accompanying Balance Sheet.

Note 13.    Goodwill and Intangible Assets

On April 2, 2018, the Company acquired all ownership interests of Huntington Steele (See Note 12). The total purchase price was allocated to Huntington Steele’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 identifiable intangible assets was recorded as goodwill. The total amount of goodwill from this transaction amounted to $11,499 and is included on the accompanying Consolidated Balance Sheets.

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.

There were no changes to the Company's goodwill during the nine months ended September 30, 2019.

The Company recognized $2,763 and $2,617 of amortization expense related to the intangible assets acquired through the acquisitions of Huntington Steele and Archway during the nine months ended September 30, 2019 and 2018, respectively.

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.

Revenues are recognized in Asset management, administration and distribution fees on the accompanying Consolidated Statements of Operations.

Investment management fees from investment management agreements - Revenues based on assets of clients of the Institutional Investors segment primarily invested in Company-sponsored products. Each client is charged an investment management fee that is stated as a percentage of the average market value of all assets under management. The client is billed directly on a quarterly basis. Revenues are recognized in Asset management, administration and distribution fees on the accompanying Consolidated Statements of Operations.

Revenues associated with the separately managed account program offered through registered investment advisors located throughout the United States.

Revenues are recognized in Asset management, administration and distribution fees on the accompanying Consolidated Statements of Operations.

Investment processing fees - Platform as a Service - Revenues associated with clients that outsource their entire investment operation and back-office processing functions. Through the use of the Company's proprietary platforms, the Company assumes all back-office investment processing services including investment processing, custody and safekeeping of assets, income collections, securities settlement and other related trust activities. The contractual fee is based on a monthly fee plus additional fees determined on a per-account or per-transaction basis. Contractual fees can also be stated as a percentage of the value of assets processed on the Company's platforms each month as long as the fee is in excess of a monthly contractual minimum.

Account fees and other - Revenues associated with custody account servicing, account terminations, reimbursements received for out-of-pocket expenses, and other fees for the provision of ancillary services.

Revenue is recognized by the Company when the performance obligations are satisfied and transfer of control to the client is completed. The majority of the Company’s performance obligations are satisfied and control is transferred to the client continuously. Therefore, revenue is recognized on a monthly basis. The amount of revenue recognized reflects the amount of consideration expected to be received by the Company in exchange for satisfied performance obligations.

The Company does not disclose the value of unsatisfied performance obligations as the majority of its contracts relate to: 1) contracts with an original term of one year or less; 2) contracts for which the Company recognizes revenue at the amount to which it has the right to invoice for services performed; and 3) contracts that are based on the value of assets under management or administration.

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 processing fees can be stated as a percentage of the value of assets processed on the our platforms. Investment operations and investment management fees are earned as a percentage of average assets under management, administration or advised assets. As of September 30, 2019, through our subsidiaries and partnerships in which we have a significant interest, we manage, advise or administer $1.0 trillion in hedge, private equity, mutual fund and pooled or separately managed assets, including $334.7 billion in assets under management and $662.0 billion in client assets under administration. Our affiliate, LSV Asset Management (LSV), manages $100.3 billion of assets which are included as assets under management.

Our Condensed Consolidated Statements of Operations for the three and nine months ended September 30, 2019 and 2018 were:

The following items had a significant impact on our financial results for the three and nine months ended September 30, 2019 and 2018:

• Revenue from Asset management, administration and distribution fees increased primarily from higher assets under administration in our Investment Managers segment. Our average assets under administration increased $77.3 billion, or 14%, to $623.9 billion in the first nine months of 2019 as compared to $546.6 billion during the first nine months of 2018. Our average assets under management, excluding LSV, decreased $1.1 billion to $228.3 billion in the first nine months of 2019 as compared to $229.4 billion during the first nine months of 2018.

• Information processing and software servicing fees in our Private Banks segment decreased by $5.9 million during the first nine months of 2019 due to decreased non-recurring fees and previously announced client losses.

• Our proportionate share in the earnings of LSV decreased to $112.8 million in the first nine months of 2019 as compared to $123.4 million in the first nine months of 2018 due to negative cash flows, lost clients, lower performance fees and lower assets under management from LSV's existing clients from the significant market depreciation in late 2018. Market appreciation and new client activity during 2019 partially offset the decline in LSV's assets under management.

Page 30 of 48

• Our operating expenses, primarily personnel costs, increased in the first nine months of 2019. These expenses are primarily related to servicing existing clients and acquiring new clients. The increase was partially offset by cost containment measures implemented in late 2018 and early 2019. These operating expenses are included in Compensation, benefits and other personnel costs on the accompanying Consolidated Statements of Operations.

• We capitalized $26.0 million in the first nine months of 2019 for the SEI Wealth Platform as compared to $32.5 million in the first nine months of 2018. Amortization expense related to SWP increased to $31.6 million during the first nine months of 2019 as compared to $29.7 million during the first nine months of 2018.

• Our effective tax rate during the third quarter of 2019 was 18.9% as compared to 18.6% during the third quarter of 2018. Our tax rate was 21.0% during the first nine months of 2019 as compared to 17.2% during the first nine months of 2018. The increase in our effective tax rate in the nine month period was primarily due to reduced tax benefits from a lower 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 2019 and purchased 5.0 million shares for $267.2 million in the nine month period.

Total revenues	$	117,250	$	118,449	(1)%	$	351,601	$	361,739	(3)%

Revenues decreased $1.2 million, or 1%, in the three month period and decreased $10.1 million, or 3%, in the nine month period ended September 30, 2019 and were primarily affected by:

• Decreased investment processing fees from the loss of clients offset by new client conversions and growth from existing clients;

• Decreased non-recurring professional services fees from existing clients as well as clients scheduled for implementation;

• Decreased investment management fees from existing international clients due to negative cash flows; and

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

Operating margins increased to 6% compared to 2% in the three month period and increased to 6% compared to 5% in the nine month period. Operating income increased by $4.5 million, or 227%, in the three month period and increased $3.8 million, or 21%, in the nine month period and was primarily affected by:

• Decreased costs, mainly personnel and consulting costs, related to maintenance, support and client migrations to SWP;

• Decreased direct expenses associated with decreased investment management fees from existing international clients; and

• Decreased direct expenses associated with client losses; partially offset by

• A decrease in revenues;

• Increased amortization expense related to SWP due to continued enhancements; and

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

Revenues increased slightly in the three month period and decreased $3.7 million, or 1%, in the nine month period ended September 30, 2019 and were primarily affected by:

• Decreased investment management fees as favorable market conditions were more than offset by negative cash flows and a decrease in average basis points earned on assets due to client-directed shifts into lower fee investment products including SEI's ETF program; partially offset by

• Increased separately managed account program fees from positive cash flows into SEI’s ETF programs.

Page 36 of 48

Operating margin increased to 50% compared to 48% in the three month period and increased to 48% compared to 47% in the nine month period. Operating income increased $2.3 million, or 5%, in the three month period and increased slightly in the nine month period and was primarily affected by:

• Decreased costs, mainly personnel and consulting costs, related to maintenance, support and client migrations to SWP;

• Decreased sales compensation expense; and

• Decreased costs associated with accounts formerly processed on TRUST 3000^® due to client migrations to SWP; partially offset by

• A decrease in revenues;

• Increased personnel costs for marketing to and servicing new advisors;

• Increased direct expenses associated with increased assets into our investment products; and

• Increased amortization expense related to SWP due to continued enhancements.

Institutional Investors

Revenues decreased $3.1 million, or 4%, in the three month period and decreased $10.8 million, or 4%, in the nine month period ended September 30, 2019 and were primarily affected by:

• Defined benefit client losses, mainly resulting from acquisitions and plan curtailments; and

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

• Asset funding from new sales of our investment management platforms; and

• Increased investment management fees from market appreciation.

Operating margin increased to 54% compared to 51% in the three month period and increased to 52% compared to 51% in the nine month period. Operating income increased slightly in the three month period and decreased $3.6 million, or 3%, in the nine month period and was primarily affected by:

• A decrease in revenues; and

• The net negative impact from foreign currency exchange rate fluctuations between the U.S. dollar and the British pound on our foreign operations; partially offset by

• Decreased direct expenses associated with investment management fees.

Investment Managers

Revenues increased $10.9 million, or 11%, in the three month period and increased $30.3 million, or 10%, in the nine month period ended September 30, 2019 and were primarily affected by:

• Positive cash flows into alternative, traditional and separately managed account offerings from new and existing clients; partially offset by

• Client losses and fund closures.

Operating margin remained at 36% in the three month period and increased to 36% compared to 35% in the nine month period. Operating income increased $4.3 million, or 12%, in the three month period and increased $13.0 million, or 13%, in the nine month period and was primarily affected by:

• An increase in revenues; and

• The net positive impact from foreign currency exchange rate fluctuations between the U.S. dollar and the Euro on our foreign operations; partially offset by

• Increased personnel expenses, technology and other operational costs to service new and existing clients; and

• Increased non-capitalized investment spending, mainly consulting costs.

Other

Corporate overhead expenses

Corporate overhead expenses primarily consist of general and administrative expenses and other costs not directly attributable to a reportable business segment. Corporate overhead expenses were $16.2 million and $14.9 million in the

Page 37 of 48

three months ended September 30, 2019 and 2018, respectively, and $52.8 million and $46.4 million in the nine months ended September 30, 2019 and 2018, respectively. The increase in corporate overhead expenses is primarily due to increased non-recurring personnel-related costs, primarily severance costs.

Other income and expense

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

	Three Months Ended September 30,						Nine Months Ended September 30,
	2019			2018			2019			2018
Net gain (loss) from investments	$	611		$	89		$	2,121		$	(460	)
Interest and dividend income	4,167			3,482			12,737			9,146
Interest expense	(154		)	(122		)	(477		)	(511		)
Equity in earnings of unconsolidated affiliate	37,609			41,726			112,758			123,406
Total other income and expense items, net	$	42,233		$	45,175		$	127,139		$	131,581

Interest and dividend income

Interest and dividend income is earned based upon the amount of cash that is invested daily. The increase in interest and dividend income in the three and nine months ended September 30, 2019 was due to an overall increase in interest rates.

Equity in earnings of unconsolidated affiliate

Equity in earnings of unconsolidated affiliate reflects our less than 50% ownership in LSV. As of September 30, 2019, our total partnership interest in LSV was 38.9%. The table below presents the revenues and net income of LSV and our proportionate share in LSV's earnings.

	Three Months Ended September 30,				Percent Change	Nine Months Ended September 30,				Percent Change
	2019		2018			2019		2018
Revenues of LSV	$	121,232	$	133,921	(9)%	$	365,164	$	397,750	(8)%
Net income of LSV	96,699		107,284		(10)%	289,918		317,295		(9)%
SEI's proportionate share in earnings of LSV	$	37,609	$	41,726	(10)%	$	112,758	$	123,406	(9)%

The decline in our earnings from LSV in the three and nine months ended September 30, 2019 was due to negative cash flows, lost clients, lower performance fees and decreased assets under management from LSV's existing clients due to the significant market depreciation in late 2018. Market appreciation and new client activity during the first nine months of 2019 partially offset the decline in LSV's assets under management. Average assets under management by LSV decreased $6.8 billion to $102.5 billion during the nine months ended September 30, 2019 as compared to $109.3 billion during the nine months ended September 30, 2018, a decrease of 6%.

Income Taxes

Our effective income tax rates for the three and nine months ended September 30, 2019 and 2018 differs from the federal income tax statutory rate due to the following:

	Three Months Ended September 30,				Nine Months Ended September 30,
	2019		2018		2019		2018
Statutory rate	21.0	%	21.0	%	21.0	%	21.0	%
State taxes, net of federal tax benefit	2.6		2.3		2.6		2.3
Foreign tax expense and tax rate differential	(0.3	)	(0.2	)	(0.2	)	(0.2	)
Tax benefit from stock option exercises	(2.2	)	(1.4	)	(1.5	)	(4.8	)
Expiration of the statute of limitations	(1.2	)	(1.0	)	(0.4	)	(0.3	)
Provision-to-return adjustment	(0.6	)	(2.3	)	(0.2	)	(0.8	)
Other, net	(0.4	)	0.2		(0.3	)	—
	18.9	%	18.6	%	21.0	%	17.2	%

Page 38 of 48

The increase in our effective tax rate for the nine months ended September 30, 2019 was primarily due to reduced tax benefits due to a lower volume of stock option exercise activity as compared to the prior year period.

Stock-Based Compensation

We recognized $15.6 million and $16.4 million in stock-based compensation expense during the nine months ended September 30, 2019 and 2018, respectively. The amount of stock-based compensation expense we recognize is based upon our estimate of when earnings per share targets may be achieved. Any change in our estimate could result in the 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 our earnings.

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. The Company's Level 3 financial liabilities at September 30, 2019 and December 31, 2018 consist entirely of the estimated contingent consideration resulting from an acquisition (See Note 12 to the Consolidated Financial Statements). We did not have any other financial liabilities at September 30, 2019 or December 31, 2018 that were required to be measured at fair value on a recurring basis (See Note 4 to the Consolidated Financial Statements).

Regulatory Matters

Like many firms operating within the financial services industry, we are experiencing a difficult and increasingly complex 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 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. From time to time, the regulators in different jurisdictions will elevate their level of scrutiny of our operations as our business expands or is deemed critical to the operations of the relevant financial markets. 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, implementation of any remediation actions, 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.

Cash, cash equivalents and restricted cash, beginning of period	758,039			747,752
Cash, cash equivalents and restricted cash, end of period	$	770,909		$	745,476

Cash requirements and liquidity needs are primarily funded through our cash flow from operations and our capacity for additional borrowing. At September 30, 2019, our unused sources of liquidity consisted of cash and cash equivalents and the amount available under our credit facility.

Our credit facility provides for borrowings of up to $300.0 million and is scheduled to expire in June 2021 (See Note 6 to the Consolidated Financial Statements). As of October 17, 2019, we had outstanding letters of credit of $11.6 million which reduced our amount available under the credit facility to $288.4 million. These letters of credit were primarily issued for the expansion of our corporate headquarters and are due to expire during the fourth quarter of 2019.

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 other than wholly-owned subsidiaries, or to incur liens or other indebtedness including contingent obligations or guarantees, 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.

Our credit facility contains terms that utilize the London InterBank Offered Rate (LIBOR) as a potential component of the interest rate to be applied to the borrowings we may undertake under the agreement (See Note 6 to the Consolidated Financial Statements). We are currently monitoring the actions of LIBOR’s regulator and the implementation of alternative reference rates in advance of the expected discontinuation of LIBOR after 2021 to determine any potential impact to our current credit facility and negotiations for subsequent borrowing agreements.

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 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 October 17, 2019, the amount of cash and cash equivalents considered free and immediately accessible for other general corporate purposes was $397.0 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 decreased $36.4 million in the first nine months of 2019 compared to the first nine months of 2018 primarily from the decrease in our net income, lower distribution payments received from our unconsolidated affiliate, LSV, and the negative impact from the change in our working capital accounts.

Page 40 of 48

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 nine months of 2019 and 2018 were as follows:

	Nine Months Ended September 30,
	2019			2018
Purchases	$	(126,030	)	$	(122,259	)
Sales and maturities	137,783			116,568
Net investing activities from marketable securities	$	11,753		$	(5,691	)

• The capitalization of costs incurred in developing computer software. We capitalized $26.8 million of software development costs in the first nine months of 2019 as compared to $33.4 million in the first nine months of 2018. 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 nine months of 2019 were $30.5 million as compared to $21.7 million in the first nine months of 2018. Our expenditures in 2019 and 2018 primarily include purchased software, equipment for our data center operations and the expansion of our corporate headquarters, which is scheduled to be completed in mid 2020. Total expenditures in 2020 related to the expansion are expected to be approximately $20.0 million.

Net cash used in financing activities includes:

• 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 $262.9 million during the first nine months of 2019 and $290.6 million during the first nine months of 2018 for the repurchase of our common stock.

• Proceeds from the issuance of our common stock. We received $41.9 million in proceeds from the issuance of our common stock during the first nine months of 2019 as compared to $78.7 million during the first nine months of 2018. The decrease in proceeds is primarily attributable to a lower level of stock option exercise activity.

• Dividend payments. Cash dividends paid were $100.7 million in the first nine months of 2019 as compared to $94.3 million in the first nine months of 2018.

• 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 March 2018 and a final payment of $20.0 million in April 2018 to repay the entire outstanding balance.

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, expansion of our corporate headquarters and future dividend payments.

The Company, its regulated subsidiaries, their regulated services and solutions 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 business process changes required or 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 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 solutions, 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, fines and changes to business processes 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 solutions 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 solutions could lead to a reduction in sales of these solutions or require modifications of these solutions.

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. 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 and other subject matter experts, review our compliance procedures, solution and service offerings, and business operations, and make changes as we deem necessary or as may be required by the applicable authority. 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 and client portfolio strategy" 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, 2018. There have been no material changes to this information as it is disclosed in our Annual Report on Form 10-K for 2018.

Item 4.    Controls and Procedures.

(a) Evaluation of Disclosure Controls and Procedures

Our management, with the participation of our Chief Executive Officer and Chief Financial Officer, evaluated the effectiveness of our disclosure controls and procedures as of the end of the period covered by this report. Based on that evaluation, the Chief Executive Officer and Chief Financial Officer concluded that our disclosure controls and procedures as of the end of the period covered by this report are effective in ensuring that information required to be disclosed by us in reports filed under the Securities Exchange Act of 1934 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 September 30, 2019 that has materially affected, or is reasonably likely to materially affect, our internal control over financial reporting. We implemented internal controls to ensure we adequately evaluated our leases and properly assessed the impact of the new accounting standard related to leases on our consolidated financial statements to facilitate the adoption of this standard on January 1, 2019 as well as the ongoing accounting under the new standard. There were no significant changes to our internal control over financial reporting during 2019 as a result of the ongoing accounting under the new accounting standard.

PART II.    OTHER INFORMATION

Item 1.    Legal Proceedings.

Stanford Trust Company Litigation

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 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 remaining 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 (“Ahders Complaint”), alleging claims essentially the same as those in Lillie. In January 2017, the Judicial Panel on Multidistrict Litigation transferred the Ahders proceeding to the Northern District of Texas and the Stanford MDL. During February 2017, SEI filed its response to the Ahders 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. In both cases, as a result of the proceedings in the Northern District of Texas, only the plaintiffs’ secondary liability claims under Section 714(B) of the Louisiana Securities Law remain. Limited discovery and motions practice have occurred, including SEI and SPTC’s filing of a dispositive summary judgment motion in the Lillie proceeding. On January 31, 2019, the Judicial Panel on Multidistrict Litigation remanded the Lillie and Ahders proceedings to the Middle District of Louisiana.

On July 9, 2019, the District Court issued an order granting SEI’s Summary Judgment Motion to dismiss the remaining Section 714(B) claim in the Lillie proceeding and denying Plaintiffs’ Motion for Continuance of SEI and SPTC’s Motion for Summary Judgment pursuant to Rule 56(d).

On July 16, 2019, SEI and SPTC filed a Motion for Summary Judgment pursuant to Rule 56(d) in the Ahders proceeding to have the remaining Section 714(B) claim dismissed.

On July 17, 2019, Plaintiffs filed a Motion for Reconsideration and/or New Trial as to the July 9, 2019 Ruling and Order (ECF 146) by the Honorable Brian A. Jackson denying a continuance of SEI’s Motion for Summary Judgment pursuant to Rule 56(d). The Court denied Plaintiffs’ Motion and entered a Final Judgment in favor of SEI on August 15, 2019.

On August 27, 2019, Plaintiffs filed a Notice of Appeal to the United States Court of Appeal for the Fifth Circuit of the District Court's dismissal of the matter. Plaintiffs’ Motion in Support of the Notice of Appeal must be filed with the Court by November 20, 2019. If Plaintiffs’ Motion in Support of Appeal is filed, SEI intends to contest the Plaintiffs' appeal.

Another case, 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.

Page 45 of 48

Two additional cases remain in the Parish of East Baton Rouge. Plaintiffs filed petitions in 2010 and have granted SEI and SPTC indefinite extensions to respond. No material activity has taken place since.

In 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 subject matter jurisdiction under the federal Securities Litigation Uniform Standards Act (SLUSA). The matters were removed to the United States District Court for the Northern District of Texas and consolidated. The court then 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 matters were 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.

SEI Capital Accumulation Plan Litigation

On September 28, 2018, a class action complaint was filed in the United States District Court for the Eastern District of Pennsylvania by Gordon Stevens, individually and as the representative of similarly situated persons, and on behalf of the SEI Capital Accumulation Plan (the “Plan”) naming the Company and its affiliated and/or related entities SEI Investments Management Corporation, SEI Capital Accumulation Plan Design Committee, SEI Capital Accumulation Plan Investment Committee, SEI Capital Accumulation Plan Administration Committee, and John Does 1-30 as defendants (the “Stevens Complaint”). The Stevens Compliant seeks unspecified damages for defendants’ breach of fiduciary duties under ERISA with respect to selecting and monitoring the Plan’s investment options and by retaining affiliated investment products in the Plan.

Although SEI believes its defenses against the plaintiff’s allegations were valid, the Company agreed to settle this matter in the very early stages of the litigation in order to avoid the high cost of protracted class-action litigation and internal distractions such cases bring. The written settlement agreement was submitted to the Court on July 26, 2019, and is a matter of public record. A Preliminary Approval Order approving the settlement agreement was issued by the Court and the Court has scheduled a fairness hearing for December 18, 2019. The settlement agreement will not be finalized until the Court has issued a final approval after the December 18, 2019. The Company expects final Court approval of the settlement by year-end. The Company expects the financial impact of the settlement agreement to be immaterial.

Other Matters

The Company is also a party to various other actions and claims arising in the normal course of business that the Company does not believe are material. The Company believes that the ultimate resolution of these matters will not have a material adverse effect on the Company's financial position or the manner in which the Company conducts its business. Currently, the Company does not believe the amount of losses associated with these matters can be estimated. While the Company does not believe that the amount of such losses will, when liquidated or estimable, be material to its financial position, the assumptions may be incorrect and any such loss could have a material adverse effect on the Company's results of operations or the manner in which the Company conducts its business in the period(s) during which the underlying matters are resolved.

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, 2018. There have been no material changes in our risk factors from those disclosed in our Annual Report on Form 10-K for 2018.

Third-Quarter Business Highlights:

• Revenues from Asset management, administration, and distribution fees increased primarily from higher assets under administration in our Investment Managers segment.

• Our average assets under administration increased $94.8 billion, or 16%, to $654.0 billion in the third-quarter 2019, as compared to $564.2 billion during the third-quarter 2018 (see attached Average Asset Balances schedules for further details).

• Our average assets under management, excluding LSV, increased $5.5 billion, or 2%, to $233.0 billion in the third-quarter 2019, as compared to $227.5 billion during the third-quarter 2018 (see attached Average Asset Balances schedules for further details).

• Sales events, net of client losses, during third-quarter 2019 totaled approximately $42.7 millionand are expected to generate net annualized recurring revenues of approximately $33.2 million when contract values are fully realized.

• Our earnings from LSV decreased by $4.1 million, or 10%, to $37.6 million in third-quarter 2019 as compared to $41.7 million in third-quarter 2018. The decrease in earnings was due to negative cash flows, client losses, reduced performance fees earned by LSV and a decline in assets under management from market depreciation.

Summary of Significant Accounting Policies

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 consist of outsourcing services including fund and investment accounting, administration, reconciliation, investor servicing and client reporting. 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 September 30, 2019, the results of operations for the three and nine months ended September 30, 2019 and 2018, and cash flows for the nine-month periods ended September 30, 2019 and 2018. 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, 2018.

The Company adopted the requirements of the Accounting Standards Update (ASU) No. 2016-2 Leases (Topic 842) (Accounting Standards Codifications (ASC) 842 (ASC 842)) using the modified retrospective method during the nine months ended September 30, 2019. As a result of the adoption of ASC 842, the Company recorded additional lease assets and net lease liabilities of $44,169 as of January 1, 2019. Upon implementation, the Company elected the package of practical expedients permitted under the transition guidance within the new standard which allowed the Company to carryforward the historical lease identification, classification and initial direct cost. ASC 842 did not materially impact the Company’s consolidated net income or consolidated cash flows (see following caption "Leases"). With the exception of the adoption of ASC 842, there have been no significant changes in significant accounting policies during the nine months ended September 30, 2019 as compared to the significant accounting policies described in the Company's Annual Report on Form 10-K for the year ended December 31, 2018.

Variable Interest Entities

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 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 $6,390 and $6,525 in fees during the three months ended September 30, 2019 and 2018, respectively. During the nine months ended September 30, 2019 and 2018, the Company waived $21,091 and $19,551, respectively, in fees.

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).

Cash and Cash Equivalents

Cash and cash equivalents includes $319,977 and $315,840 at September 30, 2019 and December 31, 2018, 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 September 30, 2019 and December 31, 2018 segregated for regulatory purposes related to trade-execution services conducted by SEI Investments (Europe) Limited. Restricted cash also includes $100 and $514 at September 30, 2019 and December 31, 2018, 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 $26,821 and $33,371 of software development costs during the nine months ended September 30, 2019 and 2018, respectively. The Company's software development costs primarily relate to significant enhancements to the SEI Wealth Platform^SM (SWP). The Company capitalized $26,029 and $32,526 of software development costs for significant enhancements to SWP during the nine months ended September 30, 2019 and 2018, respectively. As of September 30, 2019, the net book value of SWP was $283,128. The net book value includes $51,781 of capitalized software development costs in-progress associated with future releases. Capitalized software development costs in-progress associated with future releases of SWP were $42,238 as of December 31, 2018. SWP has a weighted average remaining life of 8.4 years. Amortization expense for SWP was $31,567 and $29,723 during the nine months ended September 30, 2019 and 2018, respectively.

Earnings per Share

The calculations of basic and diluted earnings per share for the three and nine months ended September 30, 2019 and 2018 are:

	Three Months Ended September 30,				Nine Months Ended September 30,
	2019		2018		2019		2018
Net income	$	132,168	$	128,319	$	372,689	$	389,834
Shares used to compute basic earnings per common share	150,855,000		156,283,000		152,009,000		157,086,000
Dilutive effect of stock options	3,372,000		4,228,000		3,302,000		4,967,000
Shares used to compute diluted earnings per common share	154,227,000		160,511,000		155,311,000		162,053,000
Basic earnings per common share	$	0.88	$	0.82	$	2.45	$	2.48
Diluted earnings per common share	$	0.86	$	0.80	$	2.40	$	2.41

During the three months ended September 30, 2019 and 2018, employee stock options to purchase 6,239,000 and 6,183,000 shares of common stock with an average exercise price of $54.91 and $53.38, respectively, were outstanding but not included in the computation of diluted earnings per common share. During the nine months ended September 30, 2019 and 2018, employee stock options to purchase 6,269,000 and 6,153,000 shares of common stock with an average exercise price of $54.84 and $53.15, respectively, were outstanding but not included in the computation of diluted earnings per common share. These options for the three and nine 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 not have been satisfied if the reporting date was the end of the contingency period or the options' 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.

Leases

The Company determines if an arrangement is a lease at the inception of the contract. The Company's operating leases are included in Operating lease right-of-use (ROU) assets, Current portion of long-term operating lease liabilities, and Long-term operating lease liabilities on the accompanying Consolidated Balance Sheet.

The operating lease ROU assets and operating lease liabilities are recognized based on the present value of future minimum lease payments over the lease term at commencement date. As most of the Company’s leases do not provide an implicit interest rate, the Company utilizes an estimated incremental borrowing rate based on the information available at commencement date in determining the present value of future payments. In determining the discount rate used in the present value calculation, the Company has elected to apply the portfolio approach for leases of equipment provided the leases commenced at or around the same time. This election allows the Company to account for leases at a portfolio level provided that the resulting accounting at this level would not differ materially from the accounting at the individual lease level. Lease expense for minimum lease payments is recognized on a straight-line basis over the lease term.

The Company has elected to account for lease and non-lease components separately. Operating lease ROU assets include all contractual lease payments and initial direct costs incurred, less any lease incentives. Facility leases generally only contain lease expense and non-component items such as taxes and pass through charges. Only the lease components are included in the ROU assets and lease liabilities. Additionally, the Company has elected not to apply the recognition requirements of ASC 842 to leases which have a lease term of less than one year at the commencement date.

The majority of the Company's leases for corporate facilities and equipment contain terms for renewal and extension of the lease agreement. The exercise of lease renewal options is generally at the Company’s sole discretion. The Company includes the lease extensions when it is reasonably certain the Company will exercise the extension. The Company’s lease agreements do not contain any material variable lease payments, material residual value guarantees or any material restrictive covenants. The Company does not currently have any finance leases.

See Note 15 for information on related disclosures regarding leases.

New Accounting Pronouncements

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) and a subsequent amendment ASU 2019-04, Codification Improvements to Topic 326, Financial Instruments-Credit Losses, Topic 815, Derivatives and Hedging, and Topic 825, Financial Instruments (ASU 2019-04) in April 2019. ASU 2016-13 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 2019-04 provides certain improvements to ASU 2016-13. ASU 2016-13 and ASU 2019-04 become effective for the Company during the first quarter of 2020. Early adoption is permitted. The Company is currently finalizing its evaluation of ASU 2016-13 and ASU 2019-04 and does not believe the adoption of the updated standards will have a material impact 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 does not believe the adoption of ASU 2017-04 will have a material impact on its consolidated financial statements and related disclosures.

In August 2018, the FASB issued ASU 2018-13, Fair Value Measurement (Topic 820): Disclosure Framework - Changes to the Disclosure Requirements for Fair Value Measurement (ASU 2018-13) which modifies the disclosure requirements

on fair value measurements. ASU 2018-13 is effective for the Company beginning in the first quarter of 2020. The Company is currently finalizing its evaluation of ASU 2018-13 and does not believe the adoption of the updated standard will have a material impact on its consolidated financial statements and related disclosures.

In October 2018, the FASB issued ASU 2018-17, Consolidation (Topic 810): Targeted Improvements to Related Party Guidance for Variable Interest Entities (ASU 2018-17). The new standard changes how entities evaluate decision-making fees under the variable interest entity guidance. ASU 2018-17 is effective for the Company beginning in the first quarter of 2020. The Company does not believe the adoption of ASU 2018-17 will have a material impact on its consolidated financial statements and related disclosures.

Revenue is recognized by the Company when the performance obligations are satisfied and transfer of control to the client is completed. The majority of the Company’s performance obligations are satisfied and control is transferred to the client continuously. Therefore, revenue is recognized on a monthly basis. The amount of revenue recognized reflects the amount of consideration expected to be received by the Company in exchange for satisfied performance obligations.

The Company does not disclose the value of unsatisfied performance obligations as the majority of its contracts relate to: 1) contracts with an original term of one year or less; 2) contracts for which the Company recognizes revenue at the amount to which it has the right to invoice for services performed; and 3) contracts that are based on the value of assets under management or administration.

Income Tax Disclosure [Abstract]

Income Taxes

Income Taxes

The gross liability for unrecognized tax benefits at September 30, 2019 and December 31, 2018 was $14,627 and $14,367, respectively, exclusive of interest and penalties, of which $14,183 and $13,774 would affect the effective tax rate if the Company were to recognize the tax benefit.

The Company classifies interest and penalties on unrecognized tax benefits as income tax expense. As of September 30, 2019 and December 31, 2018, the combined amount of accrued interest and penalties related to tax positions taken on tax returns was $1,520 and $1,289, respectively.

	September 30, 2019		December 31, 2018
Gross liability for unrecognized tax benefits, exclusive of interest and penalties	$	14,627	$	14,367
Interest and penalties on unrecognized benefits	1,520		1,289
Total gross uncertain tax positions	$	16,147	$	15,656
Amount included in Current liabilities	$	1,008	$	3,131
Amount included in Other long-term liabilities	15,139		12,525
	$	16,147	$	15,656

The Company's effective income tax rate for the three and nine months ended September 30, 2019 and 2018 differs from the federal income tax statutory rate due to the following:

	Three Months Ended September 30,				Nine Months Ended September 30,
	2019		2018		2019		2018
Statutory rate	21.0	%	21.0	%	21.0	%	21.0	%
State taxes, net of federal tax benefit	2.6		2.3		2.6		2.3
Foreign tax expense and tax rate differential	(0.3	)	(0.2	)	(0.2	)	(0.2	)
Tax benefit from stock option exercises	(2.2	)	(1.4	)	(1.5	)	(4.8	)
Expiration of the statute of limitations	(1.2	)	(1.0	)	(0.4	)	(0.3	)
Provision-to-return adjustment	(0.6	)	(2.3	)	(0.2	)	(0.8	)
Other, net	(0.4	)	0.2		(0.3	)	—
	18.9	%	18.6	%	21.0	%	17.2	%

The increase in the Company's effective tax rate for the nine months ended September 30, 2019 was primarily due to reduced tax benefits related to the lower volume of stock option exercises as compared to the nine months ended September 30, 2018.

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 2015 and is no longer subject to state, local or foreign income tax examinations by authorities for years before 2014.

The Company estimates it will recognize $1,008 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.

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's partnership interest in LSV as of September 30, 2019 was 38.9%. The Company accounts for its interest in LSV using the equity

method because of its less than 50% 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 September 30, 2019, the Company’s total investment in LSV was $41,437. The Company receives partnership distributions from LSV on a quarterly basis. The Company received partnership distributions from LSV of $123,663 and $138,216 in the nine months ended September 30, 2019 and 2018, 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 $37,609 and $41,726 during the three months ended September 30, 2019 and 2018, respectively. During the nine months ended September 30, 2019 and 2018, the Company’s proportionate share in the earnings of LSV was $112,758 and $123,406, respectively.

Line of Credit Facility [Abstract]

Line of Credit

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% to 1.00% or the London InterBank Offered Rate (LIBOR) plus a premium that can range from 1.25% to 2.00% 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%, b) the prime commercial lending rate of Wells Fargo, c) the applicable LIBOR plus 1.00%, or d) 0%. 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% of the amount of the unused portion to 0.30%, 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. The Company may issue up to $15,000 in letters of credit under the terms of the Credit Facility. The Company pays a periodic commission fee of 1.25% plus a fronting fee of 0.175% of the aggregate face amount of the outstanding letters of credit issued under the Credit Facility.

The Credit Facility contains covenants that restrict the ability of the Company to engage in mergers, consolidations, asset sales, investments, transactions with affiliates other than wholly-owned subsidiaries, or to incur liens or other indebtedness including contingent obligations or guarantees, 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. 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.

As of September 30, 2019, the Company had outstanding letters of credit of $11,553 under the Credit Facility. These letters of credit were issued primarily for the expansion of the Company's headquarters and are scheduled to expire during the remainder of 2019. The amount of the Credit Facility that is available for general corporate purposes as of September 30, 2019 was $288,447.

The Company was in compliance with all covenants of the Credit Facility during the nine months ended September 30, 2019.

Summary of Significant Accounting Policies (Policy)

Accounting Policies [Abstract]

Basis of Presentation

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 September 30, 2019, the results of operations for the three and nine months ended September 30, 2019 and 2018, and cash flows for the nine-month periods ended September 30, 2019 and 2018. 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, 2018.

The Company adopted the requirements of the Accounting Standards Update (ASU) No. 2016-2 Leases (Topic 842) (Accounting Standards Codifications (ASC) 842 (ASC 842)) using the modified retrospective method during the nine months ended September 30, 2019. As a result of the adoption of ASC 842, the Company recorded additional lease assets and net lease liabilities of $44,169 as of January 1, 2019. Upon implementation, the Company elected the package of practical expedients permitted under the transition guidance within the new standard which allowed the Company to carryforward the historical lease identification, classification and initial direct cost. ASC 842 did not materially impact the Company’s consolidated net income or consolidated cash flows (see following caption "Leases"). With the exception of the adoption of ASC 842, there have been no significant changes in significant accounting policies during the nine months ended September 30, 2019 as compared to the significant accounting policies described in the Company's Annual Report on Form 10-K for the year ended December 31, 2018.

Variable Interest Entities

Variable Interest Entities

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 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.

Revenue Recognition

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).

Cash and Cash Equivalents

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.

Cash and Cash Equivalents

Cash and cash equivalents includes $319,977 and $315,840 at September 30, 2019 and December 31, 2018, 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

Restricted cash includes $3,000 at September 30, 2019 and December 31, 2018 segregated for regulatory purposes related to trade-execution services conducted by SEI Investments (Europe) Limited. Restricted cash also includes $100 and $514 at September 30, 2019 and December 31, 2018, 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.

Leases

Leases

The Company determines if an arrangement is a lease at the inception of the contract. The Company's operating leases are included in Operating lease right-of-use (ROU) assets, Current portion of long-term operating lease liabilities, and Long-term operating lease liabilities on the accompanying Consolidated Balance Sheet.

The operating lease ROU assets and operating lease liabilities are recognized based on the present value of future minimum lease payments over the lease term at commencement date. As most of the Company’s leases do not provide an implicit interest rate, the Company utilizes an estimated incremental borrowing rate based on the information available at commencement date in determining the present value of future payments. In determining the discount rate used in the present value calculation, the Company has elected to apply the portfolio approach for leases of equipment provided the leases commenced at or around the same time. This election allows the Company to account for leases at a portfolio level provided that the resulting accounting at this level would not differ materially from the accounting at the individual lease level. Lease expense for minimum lease payments is recognized on a straight-line basis over the lease term.

The Company has elected to account for lease and non-lease components separately. Operating lease ROU assets include all contractual lease payments and initial direct costs incurred, less any lease incentives. Facility leases generally only contain lease expense and non-component items such as taxes and pass through charges. Only the lease components are included in the ROU assets and lease liabilities. Additionally, the Company has elected not to apply the recognition requirements of ASC 842 to leases which have a lease term of less than one year at the commencement date.

The majority of the Company's leases for corporate facilities and equipment contain terms for renewal and extension of the lease agreement. The exercise of lease renewal options is generally at the Company’s sole discretion. The Company includes the lease extensions when it is reasonably certain the Company will exercise the extension. The Company’s lease agreements do not contain any material variable lease payments, material residual value guarantees or any material restrictive covenants. The Company does not currently have any finance leases.

New Accounting Pronouncements

New Accounting Pronouncements

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) and a subsequent amendment ASU 2019-04, Codification Improvements to Topic 326, Financial Instruments-Credit Losses, Topic 815, Derivatives and Hedging, and Topic 825, Financial Instruments (ASU 2019-04) in April 2019. ASU 2016-13 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 2019-04 provides certain improvements to ASU 2016-13. ASU 2016-13 and ASU 2019-04 become effective for the Company during the first quarter of 2020. Early adoption is permitted. The Company is currently finalizing its evaluation of ASU 2016-13 and ASU 2019-04 and does not believe the adoption of the updated standards will have a material impact 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 does not believe the adoption of ASU 2017-04 will have a material impact on its consolidated financial statements and related disclosures.

In August 2018, the FASB issued ASU 2018-13, Fair Value Measurement (Topic 820): Disclosure Framework - Changes to the Disclosure Requirements for Fair Value Measurement (ASU 2018-13) which modifies the disclosure requirements

on fair value measurements. ASU 2018-13 is effective for the Company beginning in the first quarter of 2020. The Company is currently finalizing its evaluation of ASU 2018-13 and does not believe the adoption of the updated standard will have a material impact on its consolidated financial statements and related disclosures.

In October 2018, the FASB issued ASU 2018-17, Consolidation (Topic 810): Targeted Improvements to Related Party Guidance for Variable Interest Entities (ASU 2018-17). The new standard changes how entities evaluate decision-making fees under the variable interest entity guidance. ASU 2018-17 is effective for the Company beginning in the first quarter of 2020. The Company does not believe the adoption of ASU 2018-17 will have a material impact on its consolidated financial statements and related disclosures.

Equity Method Investments

The Company accounts for its interest in LSV using the equity

method because of its less than 50% 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.

Fair Value of Financial Instruments

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 2023 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.

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 nine months ended September 30, 2019 were consistent with those as described in our Annual Report on Form 10-K at December 31, 2018. The Company had no Level 3 financial assets at September 30, 2019 or December 31, 2018 that were required to be measured at fair value on a recurring basis.

Investments in Affiliated Funds

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.

Available-for-sale Securities

These net unrealized gains and losses are reported as a separate component of Accumulated other comprehensive loss on the accompanying Consolidated Balance Sheets.

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.

Fair Value Disclosures [Abstract]

Fair Value Measurements

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 2023 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.

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 nine months ended September 30, 2019 were consistent with those as described in our Annual Report on Form 10-K at December 31, 2018. The Company had no Level 3 financial assets at September 30, 2019 or December 31, 2018 that were required to be measured at fair value on a recurring basis. The Company's Level 3 financial liabilities at September 30, 2019 and December 31, 2018 consist entirely of the estimated contingent consideration resulting from an acquisition (See Note 12). The fair value of the contingent consideration was determined using a Monte-Carlo simulation model. Key assumptions for the Monte-Carlo simulation model include expected revenues, expected volatility, risk-free rate and correlation coefficient. There were no transfers of financial assets between levels within the fair value hierarchy during the nine months ended September 30, 2019.

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

Stockholders' Equity Note [Abstract]

Shareholders' Equity

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% when a specified diluted earnings per share target is achieved, and the remaining 50% 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 and thereafter 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 and nine months ended September 30, 2019 and 2018, respectively, as follows: 

	Three Months Ended September 30,						Nine Months Ended September 30,
	2019			2018			2019			2018
Stock-based compensation expense	$	5,453		$	5,878		$	15,555		$	16,396
Less: Deferred tax benefit	(1,042		)	(1,311		)	(2,959		)	(3,556		)
Stock-based compensation expense, net of tax	$	4,411		$	4,567		$	12,596		$	12,840

As of September 30, 2019, there was approximately $50,330 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 nine months ended September 30, 2019 was $43,246. The total options exercisable as of September 30, 2019 had an intrinsic value of $197,860. The total intrinsic value for options exercisable is calculated as

the difference between the market value of the Company’s common stock as of September 30, 2019 and the weighted average exercise price of the options. The market value of the Company’s common stock as of September 30, 2019 was $59.26 as reported by the Nasdaq Stock Market, LLC. The weighted average exercise price of the options exercisable as of September 30, 2019 was $25.08. Total options that were outstanding as of September 30, 2019 were 14,132,000. Total options that were exercisable as of September 30, 2019 were 7,890,000.

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 4,950,000 shares at a total cost of $267,184 during the nine months ended September 30, 2019, 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 September 30, 2019, the Company had approximately $198,695 of authorization remaining for the purchase of common stock under the program.

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

Cash Dividend

On May 29, 2019, the Board of Directors declared a cash dividend of $0.33 per share on the Company's common stock, which was paid on June 20, 2019, to shareholders of record on June 12, 2019. Cash dividends declared during the nine months ended September 30, 2019 and 2018 were $49,984 and $47,139, respectively.

Commitments and Contingencies Disclosure [Abstract]

Commitments and Contingencies

Commitments and Contingencies

In the ordinary course of business, the Company from time to time enters into contracts containing indemnification obligations of the Company. These obligations may require the Company to make payments to another party upon the occurrence of certain events including the failure by the Company to meet its performance obligations under the contract. These contractual indemnification provisions are often standard contractual terms of the nature customarily found in the type of contracts entered into by the Company. In many cases, there are no stated or notional amounts included in the indemnification provisions. There are no amounts reflected on the Consolidated Balance Sheets as of September 30, 2019 and December 31, 2018 related to these indemnifications.

Stanford Trust Company Litigation

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 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 remaining 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 (“Ahders Complaint”), alleging claims essentially the same as those in Lillie. In January 2017, the Judicial Panel on Multidistrict Litigation transferred the Ahders proceeding to the Northern District of Texas and the Stanford MDL. During February 2017, SEI filed its response to the Ahders 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. In both cases, as a result of the proceedings in the Northern District of Texas, only the plaintiffs’ secondary liability claims under Section 714(B) of the Louisiana Securities Law remain. Limited discovery and motions practice have occurred, including SEI and SPTC’s filing of a dispositive summary judgment motion in the Lillie proceeding. On January 31, 2019, the Judicial Panel on Multidistrict Litigation remanded the Lillie and Ahders proceedings to the Middle District of Louisiana.

On July 9, 2019, the District Court issued an order granting SEI’s Summary Judgment Motion to dismiss the remaining Section 714(B) claim in the Lillie proceeding and denying Plaintiffs’ Motion for Continuance of SEI and SPTC’s Motion for Summary Judgment pursuant to Rule 56(d).

On July 16, 2019, SEI and SPTC filed a Motion for Summary Judgment pursuant to Rule 56(d) in the Ahders proceeding to have the remaining Section 714(B) claim dismissed.

On July 17, 2019, Plaintiffs filed a Motion for Reconsideration and/or New Trial as to the July 9, 2019 Ruling and Order (ECF 146) by the Honorable Brian A. Jackson denying a continuance of SEI’s Motion for Summary Judgment pursuant to Rule 56(d). The Court denied Plaintiffs’ Motion and entered a Final Judgment in favor of SEI on August 15, 2019.

On August 27, 2019, Plaintiffs filed a Notice of Appeal to the United States Court of Appeal for the Fifth Circuit of the District Court's dismissal of the matter. Plaintiffs’ Motion in Support of the Notice of Appeal must be filed with the Court by November 20, 2019. If Plaintiffs’ Motion in Support of Appeal is filed, SEI intends to contest the Plaintiffs' appeal.

Another case, 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.

Two additional cases remain in the Parish of East Baton Rouge. Plaintiffs filed petitions in 2010 and have granted SEI and SPTC indefinite extensions to respond. No material activity has taken place since.

In 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 subject matter jurisdiction under the federal Securities Litigation Uniform Standards Act (SLUSA). The matters were removed to the United States District Court for the Northern District of Texas and consolidated. The court then 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 matters were 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.

SEI Capital Accumulation Plan Litigation

On September 28, 2018, a class action complaint was filed in the United States District Court for the Eastern District of Pennsylvania by Gordon Stevens, individually and as the representative of similarly situated persons, and on behalf of the SEI Capital Accumulation Plan (the “Plan”) naming the Company and its affiliated and/or related entities SEI Investments Management Corporation, SEI Capital Accumulation Plan Design Committee, SEI Capital Accumulation Plan Investment Committee, SEI Capital Accumulation Plan Administration Committee, and John Does 1-30 as defendants (the “Stevens Complaint”). The Stevens Compliant seeks unspecified damages for defendants’ breach of fiduciary duties under ERISA with respect to selecting and monitoring the Plan’s investment options and by retaining affiliated investment products in the Plan.

Although SEI believes its defenses against the plaintiff’s allegations were valid, the Company agreed to settle this matter in the very early stages of the litigation in order to avoid the high cost of protracted class-action litigation and internal distractions such cases bring. The written settlement agreement was submitted to the Court on July 26, 2019, and is a matter of public record. A Preliminary Approval Order approving the settlement agreement was issued by the Court and the Court has scheduled a fairness hearing for December 18, 2019. The settlement agreement will not be finalized until the Court has issued a final approval after the December 18, 2019. The Company expects final Court approval of the settlement by year-end. The Company expects the financial impact of the settlement agreement to be immaterial.

Other Matters

The Company is also a party to various other actions and claims arising in the normal course of business that the Company does not believe are material. The Company believes that the ultimate resolution of these matters will not have a material adverse effect on the Company's financial position or the manner in which the Company conducts its business. Currently, the Company does not believe the amount of losses associated with these matters can be estimated. While the Company does not believe that the amount of such losses will, when liquidated or estimable, be material to its financial position, the assumptions may be incorrect and any such loss could have a material adverse effect on the Company's results of operations or the manner in which the Company conducts its business in the period(s) during which the underlying matters are resolved.
