Item 1. Business.

Overview

After 50 years in business, SEI (NASDAQ: SEIC) remains a leading global provider of investment processing, investment management and investment operations solutions that help corporations, financial institutions, financial advisors and ultra-high-net-worth families create and manage wealth. As of December 31, 2018, through its subsidiaries and partnerships in which the company has a significant interest, SEI manages, advises or administers $883.9 billion in hedge, private equity, mutual fund and pooled or separately managed assets, including $307.3 billion in assets under management and $572.5 billion in client assets under administration. Our affiliate, LSV Asset Management (LSV), manages $96.1 billion of assets which are included as assets under management.

Our business platforms include:


•	Investment processing outsourcing platforms for providers of institutional and private-client wealth management services, including banks, trust companies, independent wealth advisers and other financial services firms;


•	Investment management platforms for institutional investors, including retirement plan sponsors, not-for-profit organizations and affluent individual investors; and


•	Investment operations outsourcing platforms for investment management firms, banks, family offices and investment companies that sponsor and distribute mutual funds, hedge funds and alternative investments.

General Development of the Business

SEI is a leading provider of wealth management business solutions for the financial services industry. For over 50 years, we've anticipated changing market needs and created innovative business solutions designed to help clients meet the challenges of managing personal and institutional wealth.

We began doing business in 1968 by providing computer-based training simulations for bank loan officers. We developed an investment accounting system for bank trust departments in 1972 and became a leading provider of investment processing outsourcing services to banks and trust institutions in the United States. Later, we broadened these outsourcing services and began offering bank clients a family of mutual funds, as well as investment operations outsourcing services. We became a public company in 1981.

We began to adapt and evolve these platforms for selected global markets in the 1990s, including: investment advisors, retirement plan sponsors and institutional investors, asset management distribution firms, investment managers and affluent individual investors. Today, we serve approximately 11,000 clients in the United States, Canada, the United Kingdom, continental Europe, South Africa and East Asia.

In each of these markets, we have combined our core competencies - investment processing, investment management and investment operations - to deliver broader and more strategic solutions for clients and markets. Today, we offer a global wealth and investment platform for private banks and wealth services firms; a complete wealth platform for operating an investment

Page 2 of 86

advisory business; a comprehensive Outsourced Chief Investment Officer (OCIO) platform for retirement plan sponsors and institutional investors; a total operational outsourcing platform for investment managers and a life and wealth platform for ultra-high-net-worth families.

Mission and Strategy

SEI’s mission is to deliver innovative and comprehensive investment processing, investment management and investment operations platforms to help clients achieve lasting success. We also seek to achieve growth in earnings and shareholder value by strengthening our position as a provider of these platforms. To achieve these objectives, we have implemented these strategies:

Create broader solutions for wealth service firms, globally. Banks, investment managers and financial advisors seek to enter new markets, expand their service offerings, provide a differentiated experience to their clients, improve efficiencies, reduce risks and better manage their businesses. We offer comprehensive platforms integrating technology, operating processes and financial products designed to help these institutions better serve their clients and create opportunities to improve their business success.

Help institutional investors manage retirement plans and operating capital, globally. Retirement plan sponsors, not-for-profit organizations and other institutional investors strive to meet their fiduciary obligations and financial objectives while reducing business risk. We deliver customized investment management solutions, as part of a complete OCIO platform, that facilitate more strategic decisions by investors about their investments and more efficient and effective management of their assets.

Support affluent individual investors in the management of their life and wealth goals, globally. Investors demand a holistic wealth management experience that focuses on their life goals and provides them with an integrated array of financial services that includes substantially more than traditional wealth management offerings. We facilitate an in-depth process of goal identification and offer comprehensive life and wealth advisory services including life planning, investments and other financial services that align closely to these goals.

Continue to expand globally. Global markets are complex, in a constant state of flux and present significant opportunities for growth. We have evolved U.S. business models for the global wealth management marketplace, focusing on the needs of institutional investors, private banks, independent wealth advisers, investment managers, investment advisors and affluent individual investors and aid them in managing the complexity of global markets.

Business Model

We are guided by the fundamental principles of our business model in managing the company:


•	Grow organically. We seek to grow organically by:


◦	delivering current platforms into existing markets and adding new clients;


◦	expanding business in existing markets by building new platforms; and


◦	entering adjacent financial markets with existing and new platforms.

We may also make acquisitions and strategic investments in other firms that we believe will expand our capabilities or acquire platforms that may increase future organic growth.


•	Engage clients. We strive to forge intimate and long lasting client relationships, and to be a thought leader in the markets we serve. We believe SEI’s long-lasting client relationships - some of which span decades - are fundamental to enhancing SEI’s financial strength.


•	Enhance financial strength. We focus on achieving long-term sustainable growth in revenues and earnings. We favor businesses and solution platforms that generate recurring revenues and predictable cash flows. We strive to maintain a strong balance sheet and return capital to shareholders through stock purchases and paid dividends.

•

Innovate. We continually invest in product development to meet the emerging needs of markets and clients, keep pace with industry developments and satisfy ever expanding and complex regulatory requirements. We have significant domain knowledge and over 50 years of experience developing new solutions that address our clients' complex business challenges in a manner that enhances their ability to compete effectively. To fuel the innovation process, we strive to nurture SEI’s talented and engaged workforce, and foster an open and collaborative culture. We believe our commitment to capital investments to drive growth - targeting eight to ten percent of annual revenues for platform development - affords us a competitive advantage.

Business Platforms

Investment Processing

Investment processing platforms consist of application and business-process-outsourcing services, professional services and transaction-based services. Investment processing services are primarily delivered through two proprietary platforms: TRUST 3000® and the SEI Wealth Platform^SM (the SEI Wealth Platform or SWP). We offer these services to providers of institutional and private-client wealth management services, including banks, trust companies, independent wealth advisers and other financial services firms. We also deliver these platforms, combined with our investment management platform, to investment advisors and other wealth management and financial services firms. Through our wholly-owned subsidiaries, we also provide business-process outsourcing services including custodial and sub-custodial services and back-office accounting services.

The TRUST 3000 platform is a comprehensive trust and investment accounting system that provides securities processing and investment accounting for all types of domestic and global securities and support for multiple account types, including personal trust, corporate trust, institutional trust and non-trust investment accounts. This platform is delivered as Software as a Service (SaaS) or as Platform as a Service (PaaS).

SWP provides a global, unified and scalable platform for operating a wealth management business. This comprehensive platform includes investment processing and infrastructure services, and advanced capabilities to support wealth advisory, asset management, and wealth administration functions. SWP also provides global wealth management capabilities including a 24/7 operating model, global securities processing, and multi-currency accounting and reporting. Built around a client-centric relationship model, SWP has an open architecture and supports workflow management and straight-through processing.

SWP is offered in SaaS and PaaS delivery modes. We began delivering SWP (PaaS) to private banks and independent wealth advisers in the United Kingdom in 2007, to banks in the United States in 2012, and to investment advisor clients in the United States in 2015. We are currently implementing our first SaaS bank client through a multi-year conversion.

Investment processing revenues are earned as monthly fees for contracted SaaS and PaaS services. Revenues are primarily earned based upon the type and number of investor accounts serviced or as a percentage of the market value of the clients’ assets processed. Professional services revenues are earned from contracted, project-oriented services, including client implementations. Transaction-based revenues are earned primarily from commissions earned on securities trades executed on behalf of clients through one of our investment processing platforms. Revenues from investment processing, professional services, and transaction-based services are recognized in Information processing and software servicing fees on the accompanying Consolidated Statements of Operations.

Investment Management

SEI's investment management platform consists of investment products including:


•	money market;


•	fixed-income and equity mutual funds;


•	collective investment products;


•	alternative investment portfolios; and


•	separately managed accounts.

Through our wholly owned subsidiaries, we serve as sponsor, administrator, transfer agent, investment advisor, distributor and shareholder servicer for many of these products. We distribute these investment products through investment advisory firms, including investment advisors and banks, and directly to institutional and individual investors.

Investment products are used to construct an investment strategy tailored to meet the needs of different investors, taking into consideration their objectives and risk tolerances. SEI's clients, or the investors served by client intermediaries, are the investors in these products. Investors typically invest in a globally diversified portfolio that consists of multiple asset classes and investment styles.

We have expanded our investment management platform to include other consultative, operational and technology components, and have created diverse solutions tailored to the needs of a specific market. These components may include investment strategies, consulting services, administrative and processing services and technology tools.

As of December 31, 2018, we managed $211.2 billion in assets including:


•	$156.0 billion invested in fixed-income and equity funds and separately managed account programs;


•	$42.9 billion invested in collective trust fund programs; and


•	$12.3 billion invested in liquidity or money market funds.

Page 4 of 86

An additional $96.1 billion in assets is managed by our unconsolidated affiliate LSV, a registered investment advisor that specializes in value equity management for its clients.

Investment management revenues are earned primarily as a percentage of net assets under management. These revenues are recognized in Asset management, administration and distribution fees on the accompanying Consolidated Statements of Operations. Our interest in the earnings of LSV is recognized in Equity in earnings of unconsolidated affiliates on the accompanying Consolidated Statements of Operations.

Investment Operations

Investment operations platforms consist of business-processing-outsourcing services including fund and investment accounting, administration, reconciliation, regulatory and compliance reporting, investor servicing and client reporting. We primarily deliver these platforms to investment management firms that offer traditional and alternative products. We support traditional managers who advise a variety of investment products including:


•	mutual funds;


•	UCITS schemes;


•	collective investment trusts (CITs);


•	exchange-traded funds (ETFs);


•	institutional accounts; and


•	separately managed accounts.

We provide comprehensive platforms to investment managers worldwide that sponsor and distribute alternative investment products such as hedge funds, funds of hedge funds, private equity funds and real estate funds, across both registered and partnership structures. We also provide an investment operations platform that services the family office market in the United States. These platforms are delivered by utilizing a highly-integrated, robust and scalable technology platform adapted to fit the specific business needs of our investment manager clients.

As of December 31, 2018, we administered $572.5 billion in client assets for traditional and alternative investment fund products, including mutual funds, hedge funds and private equity funds. Revenues from these products are earned primarily as a percentage of net assets under administration.

Revenues for the processing of institutional separate accounts and separately managed accounts are generally earned on the number of investor accounts serviced. Assets associated with this separate account processing are not included in reported assets under administration. Both revenue categories are recognized in Asset management, administration and distribution fees on the accompanying Consolidated Statements of Operations.

Business Segments

Business segments are generally organized around our target markets. Financial information about each business segment is contained in Note 12 to the Consolidated Financial Statements. Our business segments are:

Private Banks – provides outsourced investment processing and investment management platforms to banks and trust institutions, independent wealth advisers and financial advisors worldwide;

Investment Advisors – provides investment management and investment processing platforms to affluent investors through a network of independent registered investment advisors, financial planners and other investment professionals in the United States;

Institutional Investors – provides investment management and administrative outsourcing platforms to retirement plan sponsors, healthcare systems and not-for-profit organizations worldwide;

Investment Managers – provides investment operations outsourcing platforms to fund companies, banking institutions, traditional and non-traditional investment managers worldwide and family offices in the United States; and

Investments in New Businesses – focuses on providing investment management solutions to ultra-high-net-worth families residing in the United States; developing internet-based investment services and advice platforms; entering new markets; and conducting other research and development activities.

The percentage of consolidated revenues generated by our business segments for the last three years was:



	2018		2017		2016
Private Banks	30	%	31	%	33	%
Investment Advisors	25	%	24	%	23	%
Institutional Investors	20	%	21	%	22	%
Investment Managers	24	%	23	%	21	%
Investments in New Businesses	1	%	1	%	1	%
	100	%	100	%	100	%

Private Banks

We are a leading provider of investment processing outsourcing platforms for banks and trust institutions, independent wealth advisers and financial advisors worldwide.

We offer TRUST 3000 investment processing in both SaaS or PaaS delivery modes. SaaS clients outsource investment processing software services and information processing to SEI, but retain responsibility for back-office investment operations. PaaS clients also outsource investment operations, including custody and safekeeping of certain assets, income collection, securities settlement and other back-office accounting activities.

Marketing efforts in this segment are focused on SWP which is currently delivered as PaaS. SWP offers advanced capabilities across the entire range of wealth management processes, including those of large global wealth managers. SWP enables banks and investment service firms of all types to manage the growing complexity of their operations, replace legacy platforms, comply with complex regulations, and make more effective use of capital by outsourcing wealth management services.

In 2015, we signed an existing TRUST 3000 client to be the first large national bank to implement SWP, and the first client to operate SWP as SaaS. This will be a multi-year conversion due to the client’s size, the development work involved to expand SWP to be offered as SaaS, and the scope of integration activities required. While executing this large-scale implementation, we will continue to install other signed clients. We will also continue to manage our current TRUST 3000 relationships toward eventual conversion to SWP.

Contracts with TRUST 3000 clients have initial terms that are generally three to seven years in length. At December 31, 2018, we had significant relationships with 67 bank and trust institutions in the United States. Our principal competitors for this business are:


•	Fidelity National Information Services, Inc. (FIS);


•	Innovest Portfolio Solutions, LLC;


•	Charles Schwab & Co., Inc.; and


•	Fidelity Investments.

Many large financial institutions develop, operate and maintain proprietary investment and trust accounting systems. We consider these “in-house” systems to be a form of competition.

Contracts with SWP clients have initial terms that are generally five to seven years in length. At December 31, 2018, we had significant relationships with 48 banks, independent wealth advisers and other wealth managers located in the United Kingdom and the United States. Our principal competitors for this business, in addition to those named above, are:


•	Pershing LLC;


•	FNZ UK Ltd.;


•	Temenos Group AG;


•	Avaloq;


•	SS&C Technologies;


•	Fiserv, Inc.; and


•	other smaller technology firms.

We also consider “in-house” systems to be a form of competition.

This segment also offers investment management and distribution programs for banks, wealth managers and other financial services intermediaries. These programs start with SEI’s standard investment solutions, strategies, funds and investment services. We also deliver customized solutions including asset management strategies, as well as investment manager and portfolio research services. Increasingly, asset management distributors with established platforms are seeking to grow their

Page 6 of 86

businesses by offering broader investment solutions while outsourcing non-client facing investment services activities. We believe we offer our distribution partners a cost-effective way to grow their businesses and offer their investors differentiated investment choices, such as SEI’s goal-based investing solution.

We have business relationships with 282 banks, wealth managers and other financial services intermediaries at December 31, 2018. Our definition of an asset management distribution client for this segment includes financial intermediaries who have exceeded a minimal level of customer assets invested in our investment products. With the growth of our business, the minimal level of customer assets which defines a "business relationship" is adjusted from time to time. Our business is primarily based on 98 asset management distribution clients who, at December 31, 2018, had at least $5.0 million each in customer assets invested in our programs. We also had single-product relationships with 80 additional banks and trust institutions. The principal competitors for this business are:


•	Russell Investment Group;


•	Fidelity Investments;


•	Franklin Templeton Investments;


•	discretionary portfolio managers; and


•	various multi-manager investment programs offered by other firms.

We also consider “in-house” proprietary asset management capabilities to be a form of long-term competition.

Investment Advisors

We are a leading provider of investment management solutions throughout the United States to registered investment advisors, financial planners and life insurance agents, many of whom are registered with independent broker-dealers. These solutions include SEI’s investment management platform and investment processing platform and are usually offered on a bundled basis. We also help advisors manage and grow their businesses by giving them access to marketing support programs and practice management services which include, for example, workflow recommendations, succession planning advice, business assessment assistance and recommended management practices. We believe our integrated solution helps investment advisors reduce risk, improve quality and gain operational efficiency which allows them to devote more of their resources to acquiring new clients and achieving better outcomes for their existing clients.

Advisors are responsible for the investor relationship which includes creating financial plans, implementing investment strategies and educating and servicing their customers. Advisors may customize portfolios to include separate account managers provided through our programs as well as SEI-sponsored mutual funds. Our wealth and investment programs are designed to be attractive to affluent or high-net-worth individual investors and small to medium-sized institutional retirement plans.

We continually evaluate and enhance our offering to meet the emerging needs of our advisors and their end clients. We anticipate the enhanced service offerings enabled through SWP will provide a more diverse range of back-office, front-office and client-facing investment processing and investment management capabilities. We began to implement selected groups of advisor clients onto SWP in 2015 and expect to have all clients on the platform in 2019. We will continue to focus on recruiting new advisors, improving net cash flows into our investment management programs, and managing client relationships toward eventual migration onto SWP.

We estimate we have business relationships with approximately 7,400 financial advisors at December 31, 2018. Our definition of a client for this segment includes financial advisors who have exceeded a minimal level of customer assets invested in our investment products. With the growth of our business, the minimal level of customer assets which defines a "business relationship" is adjusted from time to time. Our business is primarily based on approximately 2,100 investment advisors who, at December 31, 2018, had at least $5.0 million each in customer assets invested in our programs. Revenues are earned largely as a percentage of average assets under management.

The principal competition for our investment management products is from other active money managers, passive investment management sponsors, other turnkey asset management providers, mutual fund companies, custody service providers and the proprietary investment management programs of broker dealers. In the advisor distributor channel, the principal competitors include:


•	AssetMark Investment Services Inc.;


•	Brinker Capital;


•	EnvestNet, Inc.;


•	Fidelity Investments;


•	TD Ameritrade;

Page 7 of 86


•	Charles Schwab & Co., Inc.; and


•	other broker-dealers.

As we introduce SWP, we expect to more directly compete with custody service providers.

Institutional Investors

We are a leading provider of Outsourced Chief Investment Officer (OCIO) platforms for retirement plan sponsors, healthcare systems, and not-for-profit organizations globally. We have a broadly experienced team with specific expertise in defined benefit plans, defined contribution plans, endowments, foundations, balance sheet assets and other institutional asset pools.

Our clients benefit from solutions that combine the breadth of SEI’s investment management, advisory, and administration services. Depending on their needs, objectives, and risk tolerance, clients may elect to either retain control or outsource specific management functions. As a result, they are able to integrate SEI’s investment process, advisory services, and plan administration services into their existing best practices seamlessly. This approach is designed to address the investor’s specific risk-return requirements, reduce business risk, provide ongoing due diligence, and increase operational efficiency.

SEI’s open architecture investment management approach provides access to manager research, manager selection and monitoring, portfolio construction and discretionary management. Advisory services include scenario modeling and customization of an asset allocation plan that is designed to meet long-term objectives. Plan administration services include trustee, custodial, and benefit payment services.

We expect to continue our efforts to build a globally diversified institutional client base, provide our clients with value-added advice and discretionary services, and place increased emphasis on defined contribution and not-for-profit organizations fiduciary management sales opportunities.

Fees are primarily earned as a percentage of average assets under management calculated using the average of the four month ending balances preceding the billing date. At December 31, 2018, we had relationships with 482 institutional clients. The principal competitors for this segment are:


•	boutique and large bank OCIO/fiduciary management firms;


•	Mercer;


•	Aon Hewitt;


•	Willis Towers Watson; and


•	Russell Investments.

Investment Managers

We are a leading global provider of investment operations outsourcing platforms to fund companies, banking institutions, family offices and both traditional and alternative investment managers worldwide. We provide investment organizations and asset owners with the advanced operating infrastructure that is critical to success in this highly competitive industry while also providing solutions to efficiently navigate a host of ever changing and increasingly complex business and regulatory challenges. Our comprehensive global operating platform provides clients with customized and integrated capabilities in the areas of:


•	data and information management;


•	investment operations;


•	risk management and compliance support;


•	fund administration;


•	fund accounting; and


•	distribution support.

We work with a diverse and sophisticated group of alternative, traditional, and hybrid asset managers, including approximately one-third of the top 100 managers worldwide. We believe clients choose our full-service offering because of its flexibility, quality and ability to support their diverse business needs across multiple product types and structures, investment strategies and asset classes. Our investment manager clients offer a variety of packaging types, including hedge funds, private equity and real estate funds, mutual funds, separate accounts, ETFs, UCITS and closed-end funds. For clients focused on the U.S. retirement market who desire to manage assets within a collective investment trust, we offer trustee and investment management services in addition to the aforementioned administration services. Our platform enables us to offer outsourcing services to a full spectrum of investment managers, accommodating the special needs of emerging and start-up managers all the way through to the most complex, multi-asset hybrid managers globally. Our operational platform enables managers to view

Page 8 of 86

their business in a comprehensive and integrated way, providing more insight and thus control over their business risks and results.

We also provide a family office platform with a comprehensive suite of technology and technology-enabled services for ultra-high-net-worth families, their trusted advisors and the institutions that service the family office market.

Over the past few years, investors have faced multiple market disruptions and rising volatility. At the same time there has been an increased level of regulatory pressure focused on investor and data protection. Investment managers have responded with a range of innovative products designed to better manage volatility and downside risk, and many now offer alternatives to the pure long-only investing strategy historically used in traditional markets. This can be accomplished in a standalone private or public fund vehicle or using our U.S. mutual fund series trust platform. We also offer a regulatory compliance platform that assists managers in adhering to the changing and ever-demanding global regulatory environment. Additionally, as we believe that competitiveness will increasingly be based on capabilities other than just portfolio investment expertise, we offer managers solutions that help them gain scale and efficiency, run their businesses more intelligently through data analytics and online dashboards, and be more responsive to regulatory, investor and intermediary needs.

We will continue our efforts to add new asset managers, asset owners, family offices and private wealth advisors as clientele, grow our existing client relationships, expand into new markets and further develop our solutions and global operations platform.

Contracts for fund administration outsourcing services generally have terms ranging from three to five years. Fees are primarily earned as a percentage of average assets under management and administration. A portion of the revenues for this segment is earned as account servicing fees. At December 31, 2018, we had relationships with 486 investment management companies, alternative investment managers, family offices and private wealth advisors. Our competitors vary according to the asset class or solutions provided and include:


•	State Street;


•	BNY Mellon;


•	Northern Trust;


•	SS&C Technologies; and


•	Citco.

Investments in New Businesses

The Investments in New Businesses segment represents other business ventures or research and development activities intended to expand our solutions to new or existing markets including ultra-high-net-worth families who reside in the United States. This segment also includes the costs associated with developing internet-based investment services and advice solutions. The family wealth management solution offers flexible family-office type services through a highly personalized solution while utilizing a goals-based investment process.

The principal competitors for the family wealth solution are diversified financial services providers focused on the ultra-high-net-worth market.

Research and Development

We continue to devote significant resources to research and development, including expenditures for new technology platforms, enhancements to existing technology platforms and new investment products and services. Our research and development expenditures for the last three years were:



(all dollar amounts in thousands)	2018			2017			2016
Research and development expenditures	$	159,084		$	155,252		$	134,323

Capitalization of costs incurred in developing computer software	$	44,221		$	61,043		$	50,392

Research and development expenditures as a percentage of revenues	9.8		%	10.2		%	9.6		%

Our research and development expenditures are included in Compensation, benefits and other personnel and Consulting, outsourcing and professional fees on the accompanying Consolidated Statements of Operations.

The majority of our research and development spending is related to building SWP, which combines business service processing with asset management and distribution services. SWP offers a client-centric, rather than an account-centric, process

Page 9 of 86

with model-based portfolio management services through a single platform. SWP utilizes SEI’s proprietary applications with those built by third-party providers and integrates them into a single technology platform. This integration supports straight-through business processing and enables the transformation of our clients’ wealth services from operational investment processing services to client value-added services.

SWP provides the technology infrastructure for the business solutions now being marketed and delivered to markets in the United States and the United Kingdom served by the Private Banks segment. SWP also provides the technology infrastructure for the business solutions now being marketed and delivered to markets in the United States served by the Investment Advisors segment. We believe the advanced capabilities of SWP will enable us to significantly extend and enhance the services we offer to clients and expand SEI’s addressable markets.

Marketing and Sales

Our business platforms are directly marketed to potential clients in our target markets. At January 31, 2019, we employed approximately 105 sales representatives who operate from offices located throughout the United States, Canada, the United Kingdom, continental Europe, South Africa, Asia and other locations.

Customers

In 2018, no single customer accounted for more than ten percent of revenues in any business segment.

Personnel

At January 31, 2019, we had 3,820 full-time and 32 part-time employees. Employee unions do not represent any of our employees. Management considers employee relations to be generally good.

Regulatory Considerations

We conduct our operations through several regulated wholly-owned subsidiaries. These subsidiaries are:


•	SEI Investments Distribution Co., or SIDCO, a broker-dealer registered with the SEC under the Securities Exchange Act of 1934 and a member of the Financial Industry Regulatory Authority, Inc., or FINRA;


•	SEI Investments Management Corporation, or SIMC, an investment advisor registered with the SEC under the Investment Advisers Act of 1940 and with the Commodity Futures Trading Commission, or CFTC, under the Commodity Exchange Act;


•	SEI Private Trust Company, or SPTC, a limited purpose federal thrift chartered and regulated by the Office of the Comptroller of the Currency;


•	SEI Trust Company, or STC, a Pennsylvania trust company, regulated by the Pennsylvania Department of Banking and Securities;


•	SEI Investments (Europe) Limited, or SIEL, an investment manager and financial institution subject to regulation by the Financial Conduct Authority of the United Kingdom;


•	SEI Investments Canada Company, or SEI Canada, an investment fund manager that has various other capacities that is regulated by the Ontario Securities Commission and various provincial authorities;


•	SEI Investments Global, Limited, or SIGL, a management company for Undertakings for Collective Investment in Transferable Securities, or UCITS, and for Alternative Investment Funds, or AIFs, that is regulated primarily by the Central Bank of Ireland, or CBI;


•	SEI Investments - Global Fund Services, Ltd., or GFSL, an authorized provider of administration services for Irish and non-Irish collective investment schemes that is regulated by the CBI; and


•	SEI Investments - Depositary and Custodial Services (Ireland) Limited, or D&C, an authorized provider of depositary and custodial services that is regulated by the CBI.

In addition to the regulatory authorities listed above, our subsidiaries are subject to the jurisdiction of regulatory authorities in other foreign countries. In addition to our wholly-owned subsidiaries, we also own a minority interest of approximately 38.9 percent in LSV, which is also an investment advisor registered with the SEC.

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

Page 10 of 86

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. Recent changes include the effectiveness of the Markets in Financial Instruments Directive (MiFID II) and pending effectiveness of the General Data Protection Regulation in the European Union and the U.S. Department of Labor's Fiduciary Rule. As a result of these examinations, inquiries and requests, as a result of increased civil litigation activity, and as a result of these new laws and regulations, we engage legal counsel 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” for a description of the risks that proposed regulatory changes may present for our business.

Item 1A. Risk Factors.

We believe that the risks and uncertainties described below are those that impose the greatest threat to the sustainability of our business. However, there are other risks and uncertainties that exist that may be unknown to us or, in the present opinion of our management, do not currently pose a material risk of harm to us. The risk and uncertainties facing our business, including those described below, could materially adversely affect our business, results of operations, financial condition and liquidity.

Risks Related to Our Business and Industry

Our revenues and earnings are affected by changes in capital markets. A majority of our revenues are earned based on the value of assets invested in investment products that we manage or administer. Significant fluctuations in securities prices may materially affect the value of these assets and may also influence an investor’s decision to invest in and maintain an investment in a mutual fund or other investment product. As a result, our revenues and earnings derived from assets under management and administration could be adversely affected.

We are exposed to product development risk. We continually strive to increase revenues and meet our customers' needs by introducing new products and services as well as our existing products and services. As a result, we are subject to product development risk, which may result in loss if we are unable to develop and deliver products to our target markets that address our clients' needs that are developed on a timely basis and reflect an attractive value proposition. The majority of our product development risk pertains to the SEI Wealth Platform or SWP, which provides a global, unified and scalable platform for operating a wealth management business. It is designed to improve client experience capabilities and strengthen operating efficiencies by providing straight through business processing solutions and transform the front, middle and back office operations that exist today. New product development is primarily for the purpose of enhancing our competitive position in the industry. In the event that we fail to develop new or enhance current products or services at an acceptable cost or on a timely basis or if we fail to deliver products and services which are of sound, economic value to our clients and our target markets, or an inability to support the product in a cost-effective and compliant manner, we may recognize significant financial losses.

In 2015, we signed an existing client to be the first large national bank in the United States to implement SWP, and the first client to operate SWP as an SaaS solution. This will be a multi-year conversion due to the client’s size, the development work involved to expand SWP to be offered as a SaaS solution, and the scope of integration activities required. The failure to develop and implement the contractually-agreed upon services on a timely basis for this client may result in significant financial losses and may negatively impact our ability to generate future growth in revenues derived from SWP.

We are exposed to operational risks. Our businesses are highly dependent on our ability to process and report, on a daily basis, a large number of transactions across numerous and diverse markets in many currencies. We may introduce new products or services or change processes or reporting, including in connection with new regulatory requirements, resulting in new operational risk that we may not fully appreciate or identify. Operational risk generally refers to the risk of loss resulting from our operations, including, but not limited to, improper or unauthorized execution and processing of transactions, deficiencies in our operating systems, inefficiencies in our operational business units, business disruptions and inadequacies or breaches in our internal control processes. We operate different businesses in diverse markets and are reliant on the ability of our employees and systems to process large volumes of transactions often within short time frames. In the event of a breakdown or improper operation of systems, human error or improper action by employees, we could suffer significant financial loss, regulatory sanctions or damage to our reputation. In order to mitigate and control operational risk, we continue to enhance policies and procedures that are designed to identify and manage operational risk.

We are dependent upon third-party service providers in our operations. We utilize numerous third-party service providers located in the United States, Canada, the United Kingdom and other offshore locations in our operations, in the development of new products, in the maintenance of our proprietary systems, and the business services we offer our clients. A failure by a third-party service provider or failure of their products could expose us to an inability to provide contractual services to our clients in a timely basis to process transactions for our clients accurately, or to meet our regulatory obligations. Additionally, if a third-party service provider is unable to provide these services, we may incur significant costs to either internalize some of these services, find a suitable alternative, or to compensate our clients for any losses that may be sustained as a consequence of the actions or inactions of our third-party services providers. In the event of a breakdown or improper operation of our or a direct or indirect third-party’s systems or processes or improper or unauthorized action by third parties, including consultants and subcontractors or our employees, we could suffer financial loss, an impairment to our liquidity position, a disruption of our businesses, regulatory sanctions or damage to our reputation.

We serve as the investment advisor for many of the products offered through our investment management programs and utilize the services of investment sub-advisers to manage the majority of these assets. A failure in the performance of our due diligence processes and controls related to the supervision and oversight of these firms in detecting and addressing conflicts of interest,

Page 12 of 86

fraudulent activity, noncompliance with relevant securities and other laws could cause us to suffer financial loss, regulatory sanctions or damage to our reputation.

We are dependent on third party pricing services for the valuation of securities invested in our investment products. The majority of the securities held by our investment products are valued using quoted prices from active markets gathered by external third party pricing services. Securities for which market prices are not readily available are valued in accordance with procedures applicable to that investment product. These procedures may utilize unobservable inputs that are not gathered from any active markets and involve considerable judgment. If these valuations prove to be inaccurate, our revenues and earnings from assets under management could be adversely affected.

We are dependent upon third party approvals. Many of the investment advisors through which we distribute our investment offerings are affiliated with independent broker-dealers or other networks, which have regulatory responsibility for the advisor’s practice. As part of the regulatory oversight, these broker-dealers or networks must approve the use of our investment products by affiliated advisors within their networks. Failure to receive such approval, or the withdrawal of such approval, could adversely affect the marketing of our investment products.

Our earnings and cashflows are affected by the performance of LSV. We maintain a minority ownership interest in LSV which is a significant contributor to our earnings. We also receive partnership distribution payments from LSV on a quarterly basis which contribute to our operating cashflows. LSV is a registered investment advisor that provides investment advisory services to institutions, including pension plans and investment companies. LSV is a value-oriented, contrarian money manager offering a deep-value investment alternative utilizing a proprietary equity investment model to identify securities generally considered to be out of favor by the market. Volatility in the capital markets or poor investment performance on the part of LSV, on a relative basis or an absolute basis, could result in a significant reduction in their assets under management and revenues and a reduction in performance fees. Consequently, LSV's contribution to our earnings through our minority ownership as well as to our operating cashflows through LSV's partnership distribution payments could be adversely affected.

We may be unable to fully capture the expected value from acquisitions, divestitures, joint ventures, minority stakes or strategic alliances. In connection with past or future acquisitions, divestitures, joint ventures, minority stakes or strategic alliances, we face numerous risks and uncertainties combining, transferring, separating or integrating the relevant businesses and systems, including the need to combine or separate accounting and data processing systems and management controls and to integrate relationships with clients, trading counterparties and business partners. In the case of joint ventures and minority stakes, we are subject to additional risks and uncertainties because we may be dependent upon, and subject to liability, losses or reputational damage relating to systems, controls and personnel that are not under our control.

In addition, conflicts or disagreements between us and any of our joint venture partners may negatively impact the benefits to be achieved by the relevant joint venture.

There is no assurance that any of our acquisitions or divestitures will be successfully integrated or disaggregated or yield all of the positive benefits anticipated. If we are not able to integrate or disaggregate successfully our past and future acquisitions or dispositions, there is a risk that our results of operations, financial condition and cash flows may be materially and adversely affected.

Certain of our business initiatives, including expansions of existing businesses, may bring us into contact, directly or indirectly, with individuals and entities that are not within our traditional client and counterparty base and may expose us to new asset classes and new markets. These business activities expose us to new and enhanced risks, greater regulatory scrutiny of these activities, increased credit-related, sovereign and operational risks, and reputational concerns regarding the manner in which these assets are being operated or held.

Growth of our business could increase costs and regulatory risks. Providing a platform for new businesses, integrating acquired businesses, and partnering with other firms involve a number of risks and present financial, managerial, and operational challenges. We may incur significant expenses in connection with further expansion of our existing businesses or in connection with strategic acquisitions or investments, if and to the extent they arise from time to time. Our overall profitability would be negatively affected if investments and expenses associated with such growth are not matched or exceeded by the revenues that are derived from such investment or growth. Expansion may also create a need for additional compliance, risk management and internal control procedures, and often involves the hiring of additional personnel to monitor such procedures. To the extent such procedures are not adequate to appropriately monitor any new or expanded business, we could be exposed to a material loss or regulatory sanction.

Moreover, to the extent we pursue strategic acquisitions, we may be exposed to a number of risks, including additional demands on our existing employees; additional or new regulatory requirements, operating facilities and technologies; adverse effects in the event acquired goodwill or intangible assets become impaired; and the existence of liabilities or contingencies not

Page 13 of 86

disclosed to or otherwise known by us prior to closing a transaction. These risks could result in decreased earnings and harm to the Company’s competitive position in the investment management industry.

Consolidation within our target markets may affect our business. Merger and acquisition activity within the markets we serve could reduce the number of existing and prospective clients or reduce the amount of revenue and earnings we receive from retained clients. Consolidation activities may also cause larger institutions to internalize some or all of our services. These factors may negatively impact our ability to generate future growth in revenues and earnings.

We are subject to financial and non-financial covenants which may restrict our ability to manage liquidity needs. Our $300.0 million five-year senior unsecured revolving credit facility (Credit Facility) contains financial and non-financial covenants. The non-financial covenants include restrictions on indebtedness, mergers and acquisitions, sale of assets and investments. In the event of default, we have restrictions on paying dividends and repurchasing our common stock. We have one financial covenant, the Leverage Ratio, which restricts the level of indebtedness we can incur to a maximum of 1.75 times earnings before interest, taxes, depreciation and amortization (EBITDA). We believe our primary risk is with the financial covenant if we were to incur significant unexpected losses that would impact the EBITDA calculation. This would increase the Leverage Ratio and restrict the amount we could borrow under the Credit Facility. A restriction on our ability to fully utilize our Credit Facility may negatively affect our operating results, liquidity and financial condition.

Risks Related to Our Technology

We are exposed to data and cyber security risks. Cyber security and information risks for financial institutions have significantly increased in recent years in part because of the proliferation of new technologies, the use of the internet and mobile telecommunications technologies to conduct financial transactions, and the increased sophistication and activities of organized crime, hackers, terrorists and other external extremist parties, including foreign state actors, in some circumstances as a means to promote political ends. In addition to the growing sophistication of certain parties, the commoditization of cyber tools which are able to be weaponized by less sophisticated actors has led to an increase in the exploitation of technological vulnerabilities. Any of these parties may also attempt to fraudulently induce employees, customers, clients, vendors or other third parties or users of our systems to disclose sensitive information in order to gain access to our data or that of our employees or clients. Cyber security and information security risks may also derive from human error, fraud or malice on the part of our employees or third parties, including third-party providers, or may result from accidental technological failure. In addition, third parties with whom we do business, their service providers, as well as other third parties with whom our customers do business, may also be sources of cyber security risks, particularly where activities of customers are beyond our security and control systems. A failure to safeguard the integrity and confidentiality of client data and our proprietary data from the infiltration by an unauthorized user may lead to modifications or theft of critical and sensitive data pertaining to us or our clients. We have established and continually evaluate strategies designed to protect against threats and vulnerabilities containing preventive and detective controls including, but not limited to, firewalls, intrusion detection systems, computer forensics, vulnerability scanning, server hardening, penetration testing, anti-virus software, data leak prevention, encryption and centralized event correlation monitoring. Despite our efforts to ensure the integrity of our proprietary systems and information, it is possible that we may not be able to anticipate or to implement effective preventive measures against all cyber threats, especially because the methods used change frequently or are not recognized until launched. Additionally, security breaches or disruptions of our proprietary systems, or those of our service providers, could impact our ability to provide services to our clients, which could expose us to liability for damages which may not be covered by insurance, result in the loss of customer business, damage our reputation, subject us to regulatory scrutiny or expose us to civil litigation. In addition, the failure to upgrade or maintain our computer systems, software and networks, as necessary, could also make us susceptible to breaches and unauthorized access and misuse. We may be required to expend significant additional resources to modify, investigate or remediate vulnerabilities or other exposures arising from data and cyber security risks. Furthermore, even if not directed at us specifically, attacks on other financial institutions could disrupt the overall functioning of the financial system. As a result of the importance of communications and information systems to our business, we could also be adversely affected if attacks affecting our third-party service providers impair our ability to process transactions and communicate with clients and counterparties.

Given our global footprint and the high volume of transactions we process, the large number of clients, partners, vendors and counterparties with which we do business, and the increasing sophistication of cyber attacks, a cyber attack, information or security breach could occur and persist for an extended period of time without detection. We expect that any investigation of a cyber attack would be inherently unpredictable and that it would take time before the completion of any investigation and before there is availability of full and reliable information. During such time we would not necessarily know the extent of the harm or how best to remediate it, and certain errors or actions could be repeated or compounded before they are discovered and remediated, all or any of which would further increase the costs and consequences of a cyber attack.

While many of our agreements with partners and third-party vendors include indemnification provisions, we may not be able to recover sufficiently, or at all, under such provisions to adequately offset any losses. In addition, although we maintain insurance

Page 14 of 86

coverage that may, subject to policy terms and conditions, cover certain aspects of cyber and information security risks, such insurance coverage may be insufficient to cover all losses.

The cost of managing cyber and information security risks and attacks along with complying with new and increasingly expansive regulatory requirements could adversely affect our business.

We are exposed to systems and technology risks. Through our proprietary systems, we maintain and process data for our clients that is critical to their business operations. An unanticipated interruption of service may have significant ramifications, such as lost data, damaged software codes, or delayed or inaccurate processing of transactions. As a result, the costs necessary to rectify these problems may be substantial. Our continued success also depends in part on our ability to protect our proprietary technology and solutions and to defend against infringement claims of others. We primarily rely upon trade secret law, software security measures, copyrights and confidentiality restrictions in contracts with employees, vendors and customers. Our industry is characterized by the existence of a large number of trade secrets, copyrights and the rapid issuance of patents, as well as frequent litigation based on allegations of infringement or other violations of intellectual property rights of others. A successful assertion by others of infringement claims or a failure to maintain the confidentiality and exclusivity of our intellectual property may have a material adverse effect on our business and financial results.

Risks Related to Our Competitive Environment

Pricing pressure from increased competition, disruptive technology and poor investment performance may affect our revenues and earnings. The investment management industry is highly competitive and has relatively low barriers to entry. In recent years, we have experienced, and continue to experience, pricing pressures from the introduction of new, lower-priced investment products and services and the growth of passive investing, as well as from competitor firms offering automated portfolio management and other services based on technological innovations. These new investment products and technological innovations available to both institutional and retail investors have led to a general trend towards lower fees in some segments of the investment management industry. We believe price competition and pricing pressures in these and other areas will continue as investors continue to reduce the amounts they are willing to pay and financial services firms seek to obtain market share by reducing fees or margins.

Our investment management platforms include investment management programs and back-office investment processing outsourcing services and are generally offered on a bundled basis. The breadth of our business solutions allows us to compete on a number of factors including: the performance of our investment products; the level of fees charged; the quality of our investment processing services; our reputation and position in the industry; our ability to adapt to disruptive technology developments or unforeseen market entrants and our ability to address the complex and changing needs of our clients. Increased competition on the basis of any of these factors could have an adverse impact on our competitive position resulting in a decrease in our revenues and earnings.

Our ability to maintain our existing clients and attract new clients may be negatively affected if the performance of our mutual funds and other investment products, relative to market conditions and other comparable competitive investment products, is lower. Investors may decide to place their investable funds elsewhere which would reduce the amount of assets we manage resulting in a decrease in our revenues and earnings.

External factors affecting the fiduciary management market could adversely affect us. The utilization of defined benefit plans by employers in the United States has been steadily declining. A number of our clients have frozen or curtailed their defined benefit plans resulting in slower growth in our revenues and earnings related to this market segment. Additionally, we have experienced increasing fee sensitivity and competition for certain fiduciary management services due to investor preferences toward lower-priced investment products including passive management approaches. The current growth strategies of our Institutional Investors segment include entering new global markets and placing greater emphasis on defined contribution and not-for-profit organizations fiduciary management sales opportunities. These strategies may not be successful in mitigating the impact of lower revenues and earnings caused by these external factors which could adversely affect our revenues and earnings.

Risks Related to Our Regulatory Environment

We and our clients are subject to extensive governmental regulation. Our various business activities are conducted through entities which may be registered with or regulated by the SEC and CFTC as an investment advisor, a broker-dealer, a transfer agent, or an investment company, and with federal or state banking authorities as a trust company. Our broker-dealer is also a member of FINRA and is subject to its rules and oversight. In addition, some of our foreign subsidiaries are registered with, and subject to the oversight of, regulatory authorities primarily in the United Kingdom, the Republic of South Africa, the Republic of Ireland, Canada and the Cayman Islands. Many of our clients are subject to substantial regulation by federal and state banking, securities or insurance authorities or the Department of Labor. Compliance with existing and future regulations, responding to and complying with recent regulatory activity affecting broker-dealers, investment advisors, investment companies and their service providers and financial institutions, and examination or other supervisory activities of our

Page 15 of 86

regulators or of the regulators of our clients, could have a significant impact on our operations or business or our ability to provide certain products or services.

We offer investment and banking products 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 products could lead to a reduction in sales of these products or an increase in the cost of providing these products.

The fees and assessments imposed on our regulated subsidiaries by federal, national, state and foreign regulatory authorities could have a significant impact on us. In the current regulatory environment, the frequency and scope of regulatory reform may lead to an increase in fees and assessments resulting in increased expense, or an increase or change in regulatory requirements which could affect our operations and business.

We are subject to litigation and regulatory examinations and investigations. The financial services industry faces substantial regulatory risks and litigation. Like many firms operating within the financial services industry, we are experiencing a difficult and continuously evolving regulatory environment across our markets. Our current scale and reach as a provider to the financial services industry; 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, have made this an increasingly challenging and costly regulatory environment in which to operate. These examinations or investigations could result in the identification of matters that may require remediation activities or enforcement proceedings by the regulator. The direct and indirect costs of responding to these examinations, or of defending ourselves in any litigation could be significant. Additionally, actions brought against us may result in settlements, awards, injunctions, fines and penalties. The outcome of litigation or regulatory action is inherently difficult to predict and could have an adverse effect on our ability to offer some of our products and services or our ability to maintain operations in certain jurisdictions.

We are a holding company and, therefore, may not be able to receive dividends or other payments in needed amounts from our subsidiaries. The Company is organized as a holding company, a legal entity separate and distinct from our operating entities. As a holding company without significant operations of its own, our principal assets are the shares of capital stock of our subsidiaries. We rely on dividends and other payments from these subsidiaries to meet our obligations for paying dividends to shareholders, repurchasing our common stock and corporate expenses. Certain of our subsidiaries are subject to regulatory requirements of the jurisdictions in which they operate or other restrictions that may limit the amounts those subsidiaries can pay in dividends or other payments to us. No assurance can be given that there will not be further changes in law, regulatory actions, or other circumstances that could restrict the ability of our subsidiaries to pay dividends or otherwise make payment to us. Furthermore, no assurance can be given that our subsidiaries may be able to make timely payments to us in order for us to meet our obligations.

The exit by the United Kingdom from the European Union could adversely affect our business. The referendum held in the United Kingdom announced in June 2016 led to a determination that the United Kingdom should exit the European Union (EU). As a result of the referendum, the British government formally initiated the process for withdrawal in March 2017. The terms of any withdrawal are subject to a negotiation period that could last at least two years from the initiation date. It is currently unclear how the United Kingdom's access to the EU Single Market, and the wider trading, legal and regulatory environment in which we, our clients and our counterparties operate, will be impacted and how this will affect our and their businesses and the global macroeconomic environment. The uncertainty surrounding the timing, terms and consequences of the United Kingdom's exit could adversely impact customer and investor confidence, result in additional market volatility and adversely affect our business.

Risks Related to Our Business Generally

We may incur losses as our risk management and business continuity strategies, models and processes may not be fully effective in mitigating our risk exposures in all market environments or against all types of risk. We seek to monitor and control our risk exposure through a risk and control framework encompassing a variety of separate but complementary financial, credit, operational, compliance and legal reporting systems, internal controls, management review processes and other mechanisms. Our risk management process seeks to balance our ability to profit from our business activities, with our exposure to potential losses and liabilities. While we employ a broad and diversified set of risk monitoring and risk mitigation techniques, those techniques and the judgments that accompany their application cannot anticipate every economic and financial outcome or the specifics and timing of such outcomes. As our businesses change and grow, and the markets in which we operate evolve, our risk management strategies, models and processes may not always adapt with those changes. Some of our methods of managing risk are based upon our use of observed historical market behavior and management’s judgment. As a result, these methods may not predict future risk exposures, which could be significantly greater than the historical measures indicate. In addition, the use of models in connection with risk management and numerous other critical activities presents risks that such models may be ineffective, either because of poor design or ineffective testing, improper or flawed inputs, as well as unpermitted access to such models resulting in unapproved or malicious changes to the model or its inputs. Market conditions

Page 16 of 86

in recent years have involved unprecedented dislocations and highlight the limitations inherent in using historical data to manage risk. Thus, we may, in the course of our activities, incur losses.

Despite the business contingency and security response plans we have in place, there can be no assurance that such plans will fully mitigate all potential risks to us. Our ability to conduct business may be adversely affected by a disruption in the infrastructure that supports our business and the communities where we are located, which are concentrated in the Philadelphia metropolitan area, London, and Dublin. This may include a disruption involving physical site access, cyber or information security incidents, terrorist activities, disease pandemics, catastrophic events, natural disasters, extreme weather events, electrical outage, environmental hazard, computer servers, communications or other services we use, our employees or third parties with whom we conduct business.

Although we employ backup systems for our data, those backup systems may be unavailable following a disruption, the affected data may not have been backed up or may not be recoverable from the backup, or the backup data may be costly to recover, which could adversely affect our business.

Our businesses may be adversely affected if we are unable to hire and retain qualified employees. Our performance is largely dependent on the talents and efforts of highly-skilled people; therefore, our continued ability to compete effectively in our businesses, to manage our businesses effectively and to expand into new businesses and geographic areas depends on our ability to attract new talented and diverse employees and to retain and motivate our existing employees. Factors that affect our ability to attract and retain such employees include our compensation and benefits, and our reputation as a successful business with a culture of fairly hiring, training and promoting qualified employees. Declines in our profitability, or in the outlook for our future profitability, as well as regulatory limitations on compensation levels and terms, can negatively impact our ability to hire and retain highly-qualified employees.

Competition from within the financial services and technology industries and from businesses outside the financial services and technology industries for qualified employees has often been intense.

Changes in law or regulation in jurisdictions in which our operations are located that affect taxes on our employees’ income, or the amount or composition of compensation, may also adversely affect our ability to hire and retain qualified employees in those jurisdictions. As a global financial services and technology company, we are subject to limitations on compensation practices (which may or may not affect our competitors) by regulators worldwide. These limitations, including any imposed by or as a result of future legislation or regulation, may require us to alter our compensation practices in ways that could adversely affect our ability to attract and retain talented employees.

Changes in, or interpretation of, accounting principles could affect our revenues and earnings. We prepare our consolidated financial statements in accordance with generally accepted accounting principles. A change in these principles can have a significant effect on our reported results and may even retrospectively affect previously reported results (See Note 1 to the Consolidated Financial Statements for more information).

Changes in, or interpretations of, tax rules and regulations may adversely affect our effective tax rates. Unanticipated changes in our tax rates could affect our future results of operations. Our future effective tax rates could be adversely affected by changes in tax laws or the interpretation of tax laws. We are subject to possible examinations of our income tax returns by the Internal Revenue Service and state and foreign tax authorities. We regularly assess the likelihood of outcomes resulting from these examinations to determine the adequacy of our provision for income taxes; however, there can be no assurance that the final determination of any examination will not have an adverse effect on our operating results or financial position.

Currency fluctuations could negatively affect our future revenues and earnings as our business grows globally. We operate and invest globally to expand our business into foreign markets. Our foreign subsidiaries use the local currency as the functional currency. As these businesses evolve, our exposure to changes in currency exchange rates may increase. Adverse movements in currency exchange rates may negatively affect our operating results, liquidity and financial condition.

Changes in interest rates may affect the value of our fixed-income investment securities. We own Government National Mortgage Association (GNMA) mortgage-backed securities for the sole purpose of satisfying applicable regulatory requirements imposed on our wholly-owned limited purpose federal thrift subsidiary, SPTC. The valuations of these securities are impacted by fluctuations in interest rates. Interest rates during the past several years have remained relatively low. The effect of a rising interest rate environment may negatively impact the value of these securities and thereby negatively affect our financial position and earnings.

We may become subject to stockholder activism efforts that each could cause material disruption to our business. Certain influential institutional investors and hedge funds have taken steps to involve themselves in the governance and strategic direction of certain companies due to governance or strategic related disagreements between such companies and such

stockholders. If we become subject to such stockholder activism efforts, it could result in substantial costs and a diversion of management's attention and resources, which could harm our business and adversely affect the market price of our common stock.

We rely on our executive officers and senior management. Most of our executive officers and senior management personnel do not have employment agreements with us. The loss of these individuals may have a material adverse effect on our future operations.

We may incur losses as a result of unforeseen or catastrophic events, including the emergence of a pandemic, terrorist attacks, extreme weather events or other natural disasters. The occurrence of unforeseen or catastrophic events, including the emergence of a pandemic, such as the Ebola or Zika viruses, or other widespread health emergency (or concerns over the possibility of such an emergency), terrorist attacks, extreme terrestrial or solar weather events or other natural disasters, could create economic and financial disruptions, and could lead to operational difficulties (including travel limitations) that could impair our ability to manage our businesses.

Item 1B. Unresolved Staff Comments.

None.

Item 2. Properties.

Our corporate headquarters is located in Oaks, Pennsylvania and consists of nine buildings situated on approximately 90 acres. We own and operate the land and buildings, which encompass approximately 524,000 square feet of office space and 34,000 square feet of data center space. We are currently expanding these facilities by constructing a tenth building of 104,000 square feet to be completed in the third quarter of 2020. We lease other offices which aggregate 276,000 square feet. We also own a 3,400 square foot condominium that is used for business purposes in New York, New York.

Item 3. 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.

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. No material activity has taken place since remand.

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.

All parties to the matter have agreed to participate in non-binding mediation with the goal of resolving the matter in an efficient and satisfactory manner, while avoiding protracted litigation costs. The court granted a motion to stay the litigation pending the outcome of mediation, which is scheduled for May 7, 2019, in Atlanta, Georgia.

While the outcome of this litigation remains uncertain, the defendants believe that they have valid defenses to plaintiffs’ claims and intend to defend the allegations contained in the Stevens Complaint vigorously. Because of uncertainty in the make-up of the purported class named in the Stevens Complaint, the specific theories of liability that may survive a motion for summary judgment or other dispositive motion, the lack of specificity or 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 matters set forth in the Stevens Complaint.

Other Matters

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

Significant Items Impacting Our Financial Results in 2018

Revenues increased $97.6 million, or six percent, to $1.6 billion in 2018 compared to 2017. Net income increased $101.5 million, or 25 percent, to $505.9 million and diluted earnings per share increased to $3.14 per share in 2018 compared to $2.49 per share in 2017. We believe the following items were significant to our business results during 2018:

•

Revenue growth was primarily driven by higher Asset management, administration and distribution fees from market appreciation and positive cash flows from new and existing clients throughout the majority of 2018. Market volatility and negative cash flows occurring during the fourth quarter 2018 negatively impacted our revenues from assets under management and partially offset our revenue growth. Our average assets under management, excluding LSV, increased $12.1 billion, or six percent, to $226.6 billion during 2018 as compared to $214.5 billion during 2017.


•	Our average assets under administration increased $58.0 billion, or 12 percent, to $555.6 billion during 2018 as compared to $497.6 billion during 2017 primarily from positive cash flows from new and existing clients in our

Page 22 of 86

Investment Managers segment. Assets under administration were also positively impacted from our acquisition of SEI Archway during the third quarter 2017 which resulted in an increase in asset administration fees in our Investment Managers segment of $13.1 million during 2018.

•

Information processing and software servicing fees in our Private Banks segment increased in 2018 primarily due to increased assets from new and existing clients processed on SWP; however, the adoption of new revenue recognition guidance in 2018 partially offset this increase. The impact of this new guidance reduced our revenues from research services provided by our brokerage subsidiary, SIDCO, with a corresponding reduction in our expenses related to our amounts paid under soft dollar arrangements reflected in Software royalties and other information processing costs (See the caption "Impact of Adopting Revenue Recognition Guidance" later in this discussion for more information).

•

Our proportionate share in the earnings of LSV was $159.8 million in 2018 as compared to $152.6 million in 2017, an increase of five percent. The increase was primarily due to increased assets under management from LSV's existing clients due to market appreciation. The market volatility during the fourth quarter 2018 and lower performance fees partially offset the increase in our earnings from LSV.

•

Our operating expenses, primarily personnel costs, across all of our business segments increased. These expenses primarily consist of operational, technology and marketing costs and are mainly related to our solutions offerings as well as servicing existing and acquiring new clients. In addition, our Investment Managers segment includes costs related to SEI Archway. These operating expenses are included in Compensation, benefits and other personnel costs on the accompanying Consolidated Statements of Operations.


•	We capitalized $43.4 million in 2018 for SWP as compared to $51.4 million in 2017. Amortization expense related to SWP decreased to $39.9 million during 2018 as compared to $46.5 million during 2017 due to the adjustment to the estimated useful life of certain components and functionality of SWP effective in the fourth quarter 2017 (See Note 1 to the Consolidated Financial Statements).


•	During 2018, we placed into service an application developed for the Investment Managers segment. This new offering includes components that leverage upon the current infrastructure and add significant enhancements designed to aggregate, transact and process data. Amortization expense related to the application was $5.2 million during 2018.


•	Stock-based compensation expense decreased by $12.6 million during 2018 primarily due to the increase in expense associated with the achievement of stock option vesting targets earlier than originally estimated in 2017 (See the caption "Stock-Based Compensation" later in this discussion for more information).

•

Our effective tax rate during 2018 was 17.6 percent and included the new 21.0 percent corporate tax rate and other impacts from the Tax Cut and Jobs Act (The Tax Act). Our effective tax rate was 27.4 percent during 2017 and reflected the estimated impact of the Tax Act and included a net tax benefit of $12.4 million from the re-measurement of our deferred tax liability net of the tax associated with the deemed repatriation and withholding tax of our previously undistributed foreign earnings. In addition, the rate for both periods were favorably impacted by tax benefits from stock option exercise activity (See the caption "Income Taxes" later in this discussion for more information).


•	We continued our stock repurchase program during 2018 and purchased approximately 6,744,000 shares at an average price of $60.02 per share for a total cost of $404.8 million.

Significant Items Impacting Our Financial Results in 2017

Revenues increased $125.0 million, or nine percent, to $1.5 billion in 2017 compared to 2016. Net income increased $70.6 million, or 21 percent, to $404.4 million and diluted earnings per share increased to $2.49 per share in 2017 compared to $2.03 per share in 2016. We believe the following items were significant to our business results during 2017:

•

Revenue growth was primarily driven by higher Asset management, administration and distribution fees from market appreciation and positive cash flows from new and existing clients. Our average assets under management, excluding LSV, increased $24.2 billion, or 13 percent, to $214.1 billion during 2017 as compared to $189.9 billion during 2016. Our average assets under administration increased $57.7 billion, or 13 percent, to $497.6 billion during 2017 as compared to $439.9 billion during 2016.


•	Information processing and software servicing fees in our Private Banks segment increased $16.6 million in 2017 primarily due to increased assets from new and existing clients processed on SWP and increased non-recurring professional services fees.


•	Our proportionate share in the earnings of LSV was $152.6 million in 2017 as compared to $126.1 million in 2016, an increase of 21 percent. The increase was primarily due to increased assets under management from LSV's existing clients due to market appreciation and increased performance fees associated with their investment products.


•	We capitalized $51.4 million in 2017 for SWP as compared to $39.8 million in 2016. Amortization expense related to SWP increased to $46.5 million during 2017 as compared to $45.0 million during 2016 due to continued development. We adjusted the remaining useful life of certain components and functionality of SWP effective October 1, 2017.

Page 23 of 86


•	As we continued the development of new elements of SWP, our expenses related to maintenance, enhancements and support increased. These costs are primarily recognized in personnel and consulting costs and are expensed as incurred. These increased costs primarily impacted the Private Banks and Investment Advisors business segments.


•	We also capitalized $9.7 million in 2017 as compared to $10.6 million in 2016 for new technological capabilities for the Investment Managers segment. This new offering includes components that leverage upon the current infrastructure and add significant enhancements designed to aggregate, transact and process data.


•	We recognized a $3.4 million performance fee and a corresponding $1.7 million sub-advisory expense associated with an SEI-sponsored investment product during the fourth quarter 2017. These items resulted in a positive net impact of approximately $0.01 diluted earnings per share and were reflected in the Institutional Investors segment.

•

Our operating expenses, primarily personnel costs, in our Investment Advisors and Investment Managers segments increased. These expenses primarily consist of operational, technology and marketing costs and are mainly related to servicing existing clients and acquiring new clients. These operating expenses are included in Compensation, benefits and other personnel costs on the accompanying Consolidated Statements of Operations.


•	Stock-based compensation expense increased by $20.3 million during 2017 as compared to 2016 due to the achievement of stock option vesting targets earlier than originally estimated and stock options awards granted in late 2016.

•

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

•

Our effective tax rate during 2017 was 27.4 percent as compared to 34.3 percent during 2016. Our effective tax rate for 2017 reflects the estimated impact of The Tax Act and includes a tax benefit resulting from the re-measurement of our estimated net deferred tax liability as of December 31, 2017, partially offset by a one-time transition tax relating to the estimated tax impact of the deemed repatriation and withholding tax of our previously undistributed foreign earnings. Our 2017 tax rate was also positively impacted by the adoption of a new accounting standard which requires all excess tax benefits recognized on stock-based compensation expense to be recorded as an income tax benefit in the income statement.


•	On July 3, 2017, we acquired Archway Technology Partners, LLC (SEI Archway), a provider of operating technologies and services to the family office industry, for $81.6 million in cash consideration. The results of operations of SEI Archway are included in our Investment Managers business segment.


•	We continued our stock repurchase program during 2017 and purchased approximately 4,403,000 shares at an average price of $56.36 per share for a total cost of $248.1 million.

Impact of Adopting Revenue Recognition Guidance

On January 1, 2018, we adopted Accounting Standards Update (ASU) No. 2014-09, Revenue from Contracts with Customers (Topic 606) (Accounting Standards Codification 606 (ASC 606)), which provides accounting guidance on the recognition of revenues from contracts with customers and impacts the presentation of certain revenues and expenses in our consolidated financial statements. Upon the adoption of ASC 606, we recorded a cumulative effect adjustment of $14.4 million to retained earnings as of January 1, 2018. ASC 606 is applied prospectively from January 1, 2018 and reported financial results for the prior comparable periods have not been revised.

ASC 606 did not change the accounting for the majority of our revenue arrangements and did not have a material impact to our consolidated financial statements. The impact from the adoption of ASC 606 to our financial results during 2018 is primarily related to research services provided to customers in soft-dollar arrangements by SIDCO, our broker-dealer subsidiary, and the deferral of incremental contract acquisition costs. Under the new revenue standard, fees received for research services by SIDCO are recorded net of amounts paid for the soft dollar arrangement. The amounts we paid under these arrangements were previously recorded as an expense. The impact of this change in presentation was a decline in both revenues and expenses of $16.7 million during 2018. There was no impact to our net income as a result of this change. The corresponding amounts paid for soft dollar arrangements recorded as expense in 2017 and 2016 were $14.6 million and $18.4 million, respectively. Also under the new revenue standard, costs incurred to acquire client contracts are deferred and recognized over the expected client life, which ranges from 6 to 15 years. During 2018, we deferred $8.1 million in expenses related to sales commissions costs and incurred $2.8 million of amortization expense (See Note 1 to the Consolidated Financial Statements).

Sensitivity of our revenues and earnings to capital market fluctuations and client portfolio strategy

The majority of our revenues are based on the value of assets invested in investment products that we manage or administer which are affected by changes in the capital markets and the portfolio strategy of our clients or their customers. The prevailing capital market conditions that existed during the majority of 2018 and 2017 had a net positive impact on our asset-based fees thereby increasing our base revenues; however, market volatility occurring in the fourth quarter of 2018 negatively impacted

Page 24 of 86

our asset-based fee revenues and partially offset our revenue growth. Additionally, changes in the portfolio strategy of our clients or their customers in response to the market volatility resulted in asset flows into our lower margin liquidity products and negatively impacted our earnings. Any prolonged future downturns in general capital market conditions or long-term client portfolio strategies directing significant assets into lower margin liquidity products could have adverse effects on our revenues and earnings derived from assets under management and administration.

Impact to our revenues due to client losses

During 2018 and 2017, we received notification from certain investment processing clients of our Private Banks segment of their intention to either internalize some or all of our services or transfer their business to other service providers and terminate their contracts with us. Due to the complexity involved in the deconversion process for these clients, the negative impact to our revenues and earnings from these client losses are expected to be recognized during the course of 2019 and into 2020.

Impact to our revenues from the scheduled departure of the United Kingdom from the European Union

The scheduled departure date of the United Kingdom from the European Union (EU) will occur on March 29, 2019. The terms of a withdrawal on this date or any withdrawal at a later date are currently uncertain. Various scenarios, including a "no-deal" departure or an extended period of negotiations, are possible. Approximately seven percent of our global workforce is located in the United Kingdom and approximately ten percent of our revenues in 2018 were generated in the United Kingdom. Although measures taken thus far by key members of the financial services industry may serve to mitigate the impact of a disorderly "no-deal" departure, it remains unclear how the United Kingdom's access to the EU Single Market, and the wider trading, legal and regulatory environment in which we, our clients and our counterparties operate, will be impacted. The uncertainty surrounding the timing, terms and consequences of the United Kingdom's departure from the EU could adversely impact our revenues generated from the United Kingdom.

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



	2018		2017		Percent Change		2016		Percent Change
Revenues	$	517,203	$	491,872	5	%	$	399,462	23	%
Net income	410,846		392,141		5	%	323,381		21	%

SEI's proportionate share in the earnings of LSV	$	159,791	$	152,550	5	%	$	126,103	21	%

The increase in our earnings from LSV in 2018 was primarily due to increased assets under management from LSV's existing clients due to market appreciation during the first three quarters of 2018 and cash inflows from new clients. The increase in our earnings was partially offset by a decline in performance fees and increased personnel expenses of LSV. Average assets under management by LSV increased $9.0 billion to $106.9 billion during 2018 as compared to $97.9 billion during 2017, an increase of nine percent. The increase in our earnings in 2017 was primarily due to higher assets under management from LSV's existing clients due to market appreciation and increased performance fees associated with their investment products.

Income Taxes

Our effective tax rate was 17.6 percent for 2018, 27.4 percent for 2017 and 34.3 percent for 2016. Our effective tax rate is affected by recurring items, such as the U.S. federal tax rates and tax rates in various states and foreign jurisdictions and the relative amount of income we earned in those jurisdictions. The income earned by jurisdiction has been fairly consistent. Our effective tax rate is also affected by discrete items that may occur in any given year, but are not consistent from year to year.

Page 33 of 86

Below are the most significant recurring and discrete items (See Note 11 to the Consolidated Financial Statements for more information):



Year Ended December 31,	2018		2017		2016
Statutory rate	21.0	%	35.0	%	35.0	%
State taxes, net of federal tax benefit	1.9		1.3		1.3
Foreign tax expense and tax rate differential	(0.1	)	(1.1	)	(0.8	)
Tax benefit from stock option exercises	(3.8	)	(3.9	)	—
Enactment of the Tax Cuts and Jobs Act:
Re-measurement of deferred taxes	—		(4.9	)	—
One-time transition tax on repatriation of foreign earnings and withholding tax	(0.1	)	2.6		—
Research and development tax credit	(0.8	)	(0.9	)	(0.8	)
Domestic Production Activities Deduction	—		(0.5	)	(0.6	)
Foreign Derived Intangible Income Deduction	(0.2	)	—		—
Other, net	(0.3	)	(0.2	)	0.2
	17.6	%	27.4	%	34.3	%

The Tax Cut and Jobs Act (The Tax Act) was enacted in December 2017 and included numerous changes to the current tax law including a permanent reduction in the corporate tax rate from 35.0 percent to 21.0 percent, as well as the imposition of a territorial rather than worldwide system which requires a one-time transition tax on the repatriation of previously deferred foreign earnings. Under the Tax Act, the undistributed earnings from our foreign subsidiaries are deemed repatriated. As a result, we determined that a portion of these foreign earnings are no longer indefinitely reinvested and therefore accrued foreign withholding taxes. The impact of the Tax Act to our 2017 and 2018 tax rate was a combination of a $27.1 million benefit from the initial re-measurement of our estimated net deferred tax liability as of December 31, 2017 offset by a net one-time transition tax expense of $10.7 million relating to the estimated impact of the deemed repatriation and withholding taxes of $3.2 million for our previously undistributed foreign earnings for a net tax benefit of $13.2 million.

Our effective income tax rate in 2018 included the new 21.0 percent corporate tax rate. The Tax Act also provided for a Foreign Derived Intangible Income (FDII) deduction. For 2018, we estimated a federal FDII benefit of $1.2 million, which is reflected in the tax rate above. Under the enactment of the Tax Act, the Domestic Production Activities Deduction is no longer available to us beginning in 2018.

Our effective income tax rate was affected by the adoption of ASU 2016-09, Improvements to Employee Share-Based Payment Accounting (ASU 2016-09) beginning in 2017. As required by ASU 2016-09, we no longer record excess tax benefits from stock option exercises as an increase to additional paid in capital, but record such excess tax benefits as a reduction of our income tax expense in the reporting period in which the exercises occur.

Stock-Based Compensation

During 2018, 2017 and 2016, we recognized approximately $23.8 million, $36.4 million and $16.0 million, respectively, in stock-based compensation expense. Options do not vest due to the passage of time but as a result of achievement of the financial vesting targets. Options granted in December 2017 and throughout 2018 included 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. The amount of stock-based compensation expense recognized is based upon an estimate of when the earnings per share targets may be achieved. Any change in our 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 and materially affect our earnings.

During 2018 and 2017, we revised our estimate of when certain vesting targets were expected to be achieved. These changes in estimate resulted in an increase of $1.9 million and $11.2 million in stock-based compensation expense in 2018 and 2017, respectively. The change in our estimate in 2017 resulted from the higher than expected growth in earnings from the market appreciation of our assets under management and administration and the estimated impact from the enactment of the Tax Act in December 2017.

There was approximately $68.5 million of unrecognized compensation cost related to unvested employee stock options at December 31, 2018 and we expect to recognize approximately $22.6 million in stock-based compensation costs in 2019. These amounts do not reflect any estimate of forfeitures or cancellations in future periods. Actual forfeitures and cancellations occurring in a future period will reduce our stock-based compensation expense.

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. Our Level 3 financial liabilities at December 31, 2018 consist entirely of the estimated contingent consideration of $12.1 million resulting from an acquisition (See Note 14 to the Consolidated Financial Statements). We did not have any financial liabilities at December 31, 2017 that were required to be measured at fair value on a recurring basis (See Note 4 to the Consolidated Financial Statements for more information).

Regulatory Matters

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

SEI and some of our regulated subsidiaries have undergone or been scheduled to undergo a range of periodic or thematic reviews, examinations or investigations by numerous regulatory authorities around the world, including the Office of the Comptroller of the Currency, the Securities and Exchange Commission, the Financial Industry Regulatory Authority, the Financial Conduct Authority of the United Kingdom (FCA), the Central Bank of Ireland and others. These regulatory activities typically result in the identification of matters or practices to be addressed by us or our subsidiaries and, in certain circumstances, the regulatory authorities require remediation activities or pursue enforcement proceedings against us or our subsidiaries. As described under the caption “Regulatory Considerations” in Item 1 of this report, the range of possible sanctions that are available to regulatory authorities include limitations on our ability to engage in business for specified periods of time, the revocation of registration, censures and fines. The direct and indirect costs of responding to these regulatory activities and of complying with new or modified regulations, as well as the potential financial costs and potential reputational impact against us of any enforcement proceedings that might result, is uncertain but could have a material adverse impact on our operating results or financial position.

Liquidity and Capital Resources



Year Ended December 31,	2018			2017			2016
Net cash provided by operating activities	$	588,401		$	459,903		$	434,220
Net cash used in investing activities	(123,370		)	(172,302		)	(81,585		)
Net cash used in financing activities	(443,720		)	(253,633		)	(328,672		)
Effect of exchange rate changes on cash and cash equivalents	(11,024		)	14,583			(9,923		)
Net increase in cash and cash equivalents	10,287			48,551			14,040
Cash, cash equivalents and restricted cash, beginning of year	747,752			699,201			685,161
Cash, cash equivalents and restricted cash, end of year	$	758,039		$	747,752		$	699,201

Cash requirements and liquidity needs are primarily funded through our cash flow from operations and our capacity for additional borrowing. At December 31, 2018, our unused sources of liquidity consisted of our cash and cash equivalents and the amount available under our credit facility (See Note 6 to the Consolidated Financial Statements). We adopted new accounting guidance in 2018 which requires the statement of cash flows to explain the change during the period for the total of cash, cash equivalents and amounts generally described as restricted cash or restricted cash equivalents. The prior periods were retrospectively adjusted to conform to the current period’s presentation. There was no material impact to net cash flows for 2017 or 2016 as a result of including restricted cash with cash and cash equivalents.

Our credit facility provides for borrowings of up to $300.0 million and is scheduled to expire in June 2021. As of January 31, 2019, we had outstanding letters of credit of $13.8 million which reduced our amount available under the credit facility to $286.2 million. These letters of credit were primarily issued for the expansion of our corporate headquarters and are due to expire in 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, or to incur liens, as defined in the agreement. In the event of a default under the credit facility, we would also be

Page 35 of 86

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. We currently have no borrowings under our credit facility.

The majority of our excess cash reserves are primarily placed in accounts located in the United States that invest 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 January 31, 2019, the amount of cash and cash equivalents considered free and immediately accessible for other general corporate purposes was $249.0 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 increased $128.5 million in 2018 compared to 2017 primarily from the increase in our net income, higher distributions payments received from our unconsolidated affiliate, LSV, and the net change in our working capital accounts, mainly receivables. The increase was partially offset by non-cash items such as the decrease in stock-based compensation expense. Cash flows from operations increased $25.7 million in 2017 compared to 2016 primarily from the increase in our net income, higher distributions payments received from LSV and non-cash items. The increase was partially offset by the net change in our working capital accounts, mainly receivables.

Net cash used in investing activities includes:

•Purchases, sales and maturities of marketable securities. Our purchases, sales and maturities of marketable securities during 2018, 2017 and 2016 were as follows:



	2018			2017			2016
Purchases	$	(203,460	)	$	(69,525	)	$	(73,193	)
Sales and maturities	167,876			65,830			69,293
Net investing activities from marketable securities	$	(35,584	)	$	(3,695	)	$	(3,900	)

Marketable securities purchased generally consisted of investments in short-term U.S. government agency securities through SIDCO's cash management program, additional GNMA securities to satisfy applicable regulatory requirements of SPTC and investments for the start-up of new investment products. Proceeds received from sales and maturities primarily included maturities of short-term securities owned by SIDCO and sales and principal prepayments related to the GNMA securities owned by SPTC.

•

The capitalization of costs incurred in developing computer software. We capitalized $44.2 million, $61.0 million and $50.4 million of software development costs in 2018, 2017 and 2016, respectively. Amounts capitalized primarily include costs for significant enhancements and upgrades for the expanded functionality of SWP. Our capitalized software amounts also include $9.7 million and $10.6 million in 2017 and 2016, respectively, for new technological capabilities for the Investment Managers segment. This new technology was placed into service during the first quarter of 2018.

•

Capital expenditures. Our capital expenditures in 2018, 2017 and 2016 primarily include purchased software and equipment for our data center operations. Our expenditures in 2018 also include the initial phase of the expansion of our corporate headquarters, which is scheduled to be completed in mid 2020. Total expenditures related to the expansion are expected to be approximately $33.0 million and $14.0 million in 2019 and 2020, respectively. Our expenditures in 2016 include software and equipment for a new U.S. disaster recovery site.


•	Cash paid for acquisition, net of cash acquired. We completed the acquisition of Huntington Steele in April 2018. The purchase price included a net cash payment of $5.8 million. During 2017, we acquired Archway. The net cash payment included in the purchase price related to the acquisition was $80.2 million (See Note 14 to the Consolidated Financial Statements).

Net cash used in financing activities includes:


•	Borrowings and principal repayments on revolving credit facility. In July 2017, we borrowed $40.0 million for the funding of the acquisition of Archway. We made principal payments of $30.0 million and $10.0 million during 2018 and 2017, respectively, to fully repay the outstanding balance (See Note 6 to the Consolidated Financial Statements).

Page 36 of 86


•	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. The following table lists information regarding repurchases of our common stock during 2018, 2017 and 2016:



Year	Total Number of Shares Repurchased	Average Price Paid per Share		Total Cost
2018	6,744,000	$	60.02	$	404,759
2017	4,403,000	56.36		248,114
2016	6,600,000	44.60		294,374


•	Proceeds from the issuance of our common stock. We received $88.0 million, $53.6 million and $48.3 million in proceeds from the issuance of our common stock during 2018, 2017 and 2016, respectively. The proceeds we receive from the issuance of our common stock is directly attributable to the levels of stock option exercise activity.


•	Dividend payments. Our cash dividends paid during 2018, 2017 and 2016 were as follows:



Year	Cash Dividends Paid		Cash Dividends Paid per Share
2018	$	94,318	$	0.60
2017	88,862		0.56
2016	84,686		0.52

Our Board of Directors declared a semi-annual cash dividend of $0.33 per share on December 11, 2018. The dividend was paid on January 8, 2019 for a total of $50.8 million.

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.

Contractual Obligations and Contingent Obligations

As of December 31, 2018, the Company is obligated to make payments in connection with its line of credit, operating leases, maintenance contracts and other commitments in the amounts listed below. The Company has no unrecorded obligations other than the items noted in the following table:

Line of credit (a)	$	1,365	$	643	$	487	$	235	$	—
Operating leases and maintenance agreements (b)	59,842		10,322		8,476		15,471		25,573
Contingent consideration from acquisition (c)	12,120		430		681		4,207		6,802
Other commitments (d)	3,934		3,131		—		—		803
Total	$	77,261	$	14,526	$	9,644	$	19,913	$	33,178

(c)	See Note 14 to the Consolidated Financial Statements.


(d)	Amounts include the portion of uncertain tax liabilities classified as a current liability and the estimated tax impact of the deemed repatriation of our previously undistributed foreign earnings associated with the Tax Act. The actual cash payment associated with these commitments may differ. See Note 11 to the Consolidated Financial Statements.

Critical Accounting Policies

The accompanying consolidated financial statements and supplementary information were prepared in accordance with accounting principles generally accepted in the United States. Our significant accounting policies are discussed in Note 1 to the Consolidated Financial Statements. Inherent in the application of many of these accounting policies is the need for management to make estimates and judgments in the determination of certain revenues, expenses, assets and liabilities. Materially different financial results can occur as circumstances change and additional information becomes known. We believe that the following accounting policies require extensive judgment by our management to determine the recognition and timing of amounts recorded in our financial statements.

Page 37 of 86

Revenue Recognition:

Our revenues are based on contractual arrangements. 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 we expect to be entitled in exchange for those promised goods or services. Certain portions of our revenues involve a third party in providing goods or services to our customers. In such circumstances, we must determine whether the nature of our promise to the customer is to provide the underlying goods or services (we are 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 received by us in advance of the performance of services is deferred and recognized as revenue when earned. Our principal sources of revenues are: (1) asset management, administration and distribution fees calculated as a percentage of the total average daily net assets under management or administration; (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 our clients' assets processed on our platforms, or non-recurring and based upon project-oriented contractual agreements related to client implementations; and (3) transaction-based fees for providing trade-execution services.

Computer Software Development Costs:

We utilize internally developed computer software as part of our product offerings. In the development of a new software product, substantial consideration must be given by management to determine whether costs incurred are research and development costs, or internal software development costs eligible for capitalization. Management must consider a number of different factors during their evaluation of each computer software development project that includes estimates and assumptions. Costs considered to be research and development are expensed as incurred. After meeting specific requirements, internal software development costs are capitalized as incurred. The capitalization and ongoing assessment of recoverability of software development costs requires considerable judgment by management with respect to certain external factors, including, but not limited to, technological and economic feasibility, and estimated economic life. Amortization of capitalized software development costs begins when the product is ready for its intended use. Capitalized software development costs are amortized on a project basis using the straight-line method over the estimated economic life of the product or enhancement.

We evaluate the carrying value of our capitalized software when circumstances indicate the carrying value may not be recoverable. The review of capitalized software for impairment requires significant assumptions about operating strategies, underlying technologies utilized, and external market factors. Our capitalized software was developed using mainstream technologies that are industry standards and are based on technology developed by multiple vendors that are significant industry leaders. External market factors include, but are not limited to, expected levels of competition, barriers to entry by potential competitors, stability in the target market and governmental regulations.

Income Tax Accounting:

We use the asset and liability method of accounting for income taxes. Under this method, income tax expense is recognized for the amount of taxes payable or refundable for the current year. In addition, deferred tax assets and liabilities are recognized for the expected future tax consequences of temporary differences between the financial reporting and tax bases of assets and liabilities, and for operating losses and tax credit carryforwards. Management must make assumptions, judgments and estimates to determine our current provision for income taxes and also our deferred tax assets and liabilities and any valuation allowance to be recorded against a deferred tax asset.

Our assumptions, judgments and estimates relative to the current provision for income taxes take into account current tax laws, our interpretation of current tax laws and possible outcomes of current and future audits conducted by foreign and domestic tax authorities. We have established reserves for income taxes to address potential exposures involving tax positions that could be challenged by tax authorities. Although we believe our assumptions, judgments and estimates are reasonable, changes in tax laws or our interpretation of tax laws and the resolution of any future tax audits could significantly impact the amounts provided for income taxes in our consolidated financial statements.

Our assumptions, judgments and estimates relative to the value of a deferred tax asset take into account predictions of the amount and category of future taxable income, such as income from operations or capital gains income. Actual operating results and the underlying amount and category of income in future years could render our current assumptions, judgments and estimates of recoverable net deferred taxes inaccurate. Any of the assumptions, judgments and estimates mentioned above could cause our actual income tax obligations to differ from our estimates, thus materially impacting our financial position and results of operations.

Page 38 of 86

Stock-Based Compensation:

Stock-based compensation cost is measured at the grant date based on the fair value of the award and is recognized as expense over the requisite service period, which is the vesting period. We currently use the Black-Scholes option pricing model to determine the fair value of stock options. The determination of the fair value of stock-based payment awards on the date of grant using an option-pricing model is affected by our stock price as well as various other assumptions. These assumptions include our expected stock price volatility over the term of the awards, actual and projected employee stock option exercise behaviors, risk-free interest rate and expected dividends. We account for forfeitures as they occur. The amount of stock-based compensation expense that is recognized in a given period is dependent upon management’s estimate of when the earnings per share targets are expected to be achieved. If this estimate proves to be inaccurate, the remaining amount of stock-based compensation expense could be accelerated, spread out over a longer period, or reversed. We currently base our expectations for these assumptions from historical data and other applicable factors. These expectations are subject to change in future periods.

The assessment of critical accounting policies is not meant to be an all-inclusive discussion of the uncertainties to financial results that can occur from the application of the full range of our accounting policies. Materially different financial results could occur in the application of other accounting policies as well. Also, materially different results can occur upon the adoption of new accounting standards.

Information required by this item is set forth under the captions "Our revenues and earnings are affected by changes in capital markets" and "Changes in interest rates may affect the value of our fixed-income investment securities" in Item 1A "Risk Factors" and under the caption "Sensitivity of our revenues and earnings to capital market fluctuations" in Item 7 "Management's Discussion and Analysis of Financial Condition and Results of Operations."

SEI Investments Company:

Opinion on the Consolidated Financial Statements

We have audited the accompanying consolidated balance sheets of SEI Investments Company and subsidiaries (the Company) as of December 31, 2018 and 2017, the related consolidated statements of operations, comprehensive income, changes in equity, and cash flows for each of the years in the three‑year period ended December 31, 2018, and the related notes and financial statement Schedule II referred to in Item 15(2) of this Form 10-K (collectively, the consolidated financial statements). In our opinion, the consolidated financial statements present fairly, in all material respects, the financial position of the Company as of December 31, 2018 and 2017, and the results of its operations and its cash flows for each of the years in the three‑year period ended December 31, 2018, in conformity with U.S. generally accepted accounting principles.

We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States) (PCAOB), the Company’s internal control over financial reporting as of December 31, 2018, based on criteria established in Internal Control - Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission, and our report dated February 25, 2019 expressed an unqualified opinion on the effectiveness of the Company’s internal control over financial reporting.

Changes in Accounting Principle

As discussed in Note 1 to the consolidated financial statements, the Company has changed its method of accounting for revenue recognition in 2018 due to the adoption of Accounting Standards Update 2014-09, Revenue from Contracts with Customers.

As discussed in Note 1 to the consolidated financial statements, the Company has changed its method of accounting for stock based compensation in 2017 due to the adoption of Accounting Standards Update 2016-09, Improvements to Employee Share-Based Payment Accounting.

Basis for Opinion

These consolidated financial statements are the responsibility of the Company’s management. Our responsibility is to express an opinion on these consolidated financial statements based on our audits. We are a public accounting firm registered with the PCAOB and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.

We conducted our audits in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the consolidated financial statements are free of material misstatement, whether due to error or fraud. Our audits included performing procedures to assess the risks of material misstatement of the consolidated financial statements, whether due to error or fraud, and performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the consolidated financial statements. Our audits also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the consolidated financial statements. We believe that our audits provide a reasonable basis for our opinion.

SEI Investments Company:

Opinion on Internal Control Over Financial Reporting

We have audited SEI Investments Company and subsidiaries’ (the Company) internal control over financial reporting as of December 31, 2018, based on criteria established in Internal Control - Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission. In our opinion, the Company maintained, in all material respects, effective internal control over financial reporting as of December 31, 2018, based on criteria established in Internal Control - Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission.

We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States) (PCAOB), the consolidated balance sheets of the Company as of December 31, 2018 and 2017, the related consolidated statements of operations, comprehensive income, changes in equity, and cash flows for each of the years in the three-year period ended December 31, 2018, and the related notes and financial statement Schedule II referred to in Item 15(2) of this Form 10-K (collectively, the consolidated financial statements), and our report dated February 25, 2019 expressed an unqualified opinion on those consolidated financial statements.

Basis for Opinion

The Company’s management is responsible for maintaining effective internal control over financial reporting and for its assessment of the effectiveness of internal control over financial reporting, included in the accompanying Management's Report on Internal Control over Financial Reporting (Item 9A). Our responsibility is to express an opinion on the Company’s internal control over financial reporting based on our audit. We are a public accounting firm registered with the PCAOB and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.

We conducted our audit in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether effective internal control over financial reporting was maintained in all material respects. Our audit of internal control over financial reporting included obtaining an understanding of internal control over financial reporting, assessing the risk that a material weakness exists, and testing and evaluating the design and operating effectiveness of internal control based on the assessed risk. Our audit also included performing such other procedures as we considered necessary in the circumstances. We believe that our audit provides a reasonable basis for our opinion.

Definition and Limitations of Internal Control Over Financial Reporting

A company’s internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. A company’s internal control over financial reporting includes those policies and procedures that (1) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the company; (2) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the company are being made only in accordance with authorizations of management and directors of the company; and (3) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of the company’s assets that could have a material effect on the financial statements.

Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.

Notes to Consolidated Financial Statements		SEI Investments Company
(all figures are in thousands except share and per-share data)		and Subsidiaries

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 other various locations throughout the world. Investment processing platforms consist of application and business process outsourcing services, professional services and transaction-based services. Revenues from investment processing platforms are recognized in Information processing and software servicing fees on the accompanying Consolidated Statements of Operations.

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

Investment operations platforms offer investment managers support for traditional investment products such as mutual funds, collective investment trusts, exchange-traded funds, and institutional and separate accounts, by providing outsourcing services including fund and investment accounting, administration, reconciliation, investor servicing and client reporting. These platforms also provide support to managers focused on alternative investments who manage hedge funds, funds of hedge funds, private equity funds and real estate funds, across registered, partnership and separate account structures domiciled in the United States and overseas. Revenues from investment operations platforms are recognized in Asset management, administration and distribution fees on the accompanying Consolidated Statements of Operations.

Principles of Consolidation

The Consolidated Financial Statements include the accounts of the Company and its wholly-owned subsidiaries and entities in which it holds a controlling financial interest. The Company determines whether it has a controlling financial interest either by its decision-making ability through voting interests or by the extent of the Company’s participation in the economic risks and rewards of the entity through variable interests. The Company’s principal subsidiaries are SEI Investments Distribution Co. (SIDCO), SEI Investments Management Corporation (SIMC), SEI Private Trust Company (SPTC), SEI Trust Company (STC), SEI Global Services, Inc. (SGSI) and SEI Investments (Europe) Limited (SIEL). All intercompany accounts and transactions have been eliminated.

The Company accounts for investments in unconsolidated entities that are 20 percent to 50 percent owned or are 20 percent or less owned and have the ability to exercise significant influence over the operating and financial policies of the entity under the equity method of accounting. Under this method of accounting, the Company’s interest in the net assets of unconsolidated entities is reflected in Investment in unconsolidated affiliates on the accompanying Consolidated Balance Sheet and its interest in the earnings or losses of unconsolidated entities is reflected in Equity in earnings of unconsolidated affiliates on the accompanying Consolidated Statement of Operations. Any investments in entities not consolidated or accounted for under the equity method are accounted for under the cost method of accounting.

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

Page 50 of 86

pooled investment vehicles. For this reason, the Company also concluded that it is not required to consolidate the pooled investment vehicles under the voting interest entity (VOE) model.

The Company is a party to expense limitation agreements with certain SEI-sponsored money market funds subject to Rule 2a-7 of the Investment Company Act of 1940 which establish a maximum level of ordinary operating expenses incurred by the fund in any fiscal year including, but not limited to, fees of the administrator or its affiliates. Under the terms of these agreements, the Company waived $26,229, $27,434 and $41,227 in fees during 2018, 2017 and 2016, respectively.

Management’s Use of Estimates

The preparation of financial statements in conformity with accounting principles generally accepted in the United States (U.S. GAAP) requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates.

Revenue Recognition

The Company adopted the requirements of Accounting Standards Update (ASU) No. 2014-09, Revenue from Contracts with Customers (Topic 606) (Accounting Standards Codification (ASC) 606 (ASC 606)) using the modified retrospective method on January 1, 2018. As a result of the adoption of ASC 606, the Company recorded a cumulative effect adjustment of $14,402 to retained earnings as of January 1, 2018. Prior period information has not been restated.

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

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

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

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

•Research services provided by SIDCO, the Company’s broker-dealer subsidiary, to customers in soft-dollar arrangements were determined to be a separate performance obligation. Research services provided by a broker-dealer may be internally generated or provided by a third party and paid directly by the broker-dealer on the customer’s behalf. It was determined that SIDCO is considered an agent since it does not control the research services before they are transferred to the customer. Therefore, fees received for research services should be recorded in revenues net of amounts paid for the soft-dollar arrangement. These amounts paid by the Company were previously recorded gross as an expense and, beginning January 1, 2018, are recorded net of any revenue recognized. The amounts related to soft-dollar arrangements during 2018, 2017 and 2016 were $16,680, $14,623 and $18,409, respectively.

•Incremental contract acquisition costs related to information processing contracts in the Private Banks segment and investment operations contracts in the Investment Managers segment will be deferred and amortized using the straight-line method over the expected client life, which ranges from 6 to 15 years. These costs primarily consist of sales compensation payments to the Company's sales personnel. As a result, incremental contract acquisition costs are capitalized and subsequently amortized. The Company recorded a cumulative effect adjustment associated with the capitalization of contract costs of $18,641 as of January 1, 2018. For the Company's other sales compensation payments, the Company either applies the practical

Page 51 of 86

expedient permitting the expensing of costs to obtain a contract when the expected amortization period is one year or less or there are no contract acquisition costs required to be deferred under the requirements of ASC 606.

Cash and Cash Equivalents

The Company considers investment instruments purchased with an original maturity of three months or less to be cash equivalents. The Company adopted ASU No. 2016-18, Statement of Cash Flows, Restricted Cash (Topic 230) (ASU 2016-18) on January 1, 2018 which requires that a statement of cash flows explain the change during the period for the total of cash, cash equivalents, and amounts generally described as restricted cash or restricted cash equivalents. The prior periods were retrospectively adjusted to conform to the current period’s presentation. There was no material impact to net cash flows for 2017 or 2016 as a result of including restricted cash with cash and cash equivalents when reconciling the beginning-of-period and end-of-period total amounts presented on the accompanying Consolidated Condensed Statement of Cash Flows in accordance with ASU 2016-18.

Cash and cash equivalents include $315,840 and $401,292 at December 31, 2018 and 2017, respectively, primarily invested in SEI-sponsored open-ended money market mutual funds. The SEI-sponsored mutual funds are considered Level 1 assets.

Restricted Cash

Restricted cash includes $3,000 at December 31, 2018 and 2017 segregated for regulatory purposes related to trade-execution services conducted by SIEL. Restricted cash also includes $514 and $505 at December 31, 2018 and 2017, respectively, segregated in special reserve accounts for the benefit of SIDCO customers in accordance with certain rules established by the Securities and Exchange Commission for broker-dealers.

Allowances for Doubtful Accounts

The Company provides an allowance for doubtful accounts equal to the estimated uncollectible amounts. The Company’s estimate is based on historical collection experience and a review of the current status of trade accounts receivable.

Concentration of Credit Risk

Financial instruments which potentially expose the Company to concentrations of credit risk consist primarily of cash equivalents and trade receivables. Cash equivalents are principally invested in short-term money market funds or placed with major banks and high-credit qualified financial institutions. Cash deposits maintained with institutions are in excess of federally insured limits. Concentrations of credit risk with respect to the Company's receivables are limited due to the large number of clients and their dispersion across geographic areas. No single group or customer represents greater than ten percent of total accounts receivable.

Property and Equipment

Property and Equipment are recorded at cost. Expenditures for major additions and improvements are capitalized and minor replacements, maintenance, and repairs are charged to expense as incurred. Construction in progress includes the cost of construction and other direct costs attributable to the construction. When property and equipment are retired or disposed of, the related cost and accumulated depreciation are removed from the accounts and any resulting gain or loss is included in the results of operations for the respective period. Depreciation is provided over the estimated useful lives using the straight line method for financial statement purposes. No provision for depreciation is made for construction in progress until such time as the relevant assets are completed and put into service. The Company uses other depreciation methods, generally accelerated, for tax purposes where appropriate. Buildings and building improvements are depreciated over 25 to 39 years. Equipment, purchased software and furniture and fixtures have useful lives ranging from 3 to 5 years. Amortization of leasehold improvements is computed using the straight line method over the shorter of the remaining lease term or the estimated useful lives of the improvements.

Marketable Securities

The classification of investments in marketable securities is determined at the time of purchase and reevaluated at each balance sheet date. Debt and equity securities classified as available-for-sale are reported at fair value as determined by the most recently traded price of each security at the balance sheet date.

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

Unrealized gains and losses associated with the Company's available for sale debt securities, net of income taxes, are reported as a separate component of comprehensive income. SIDCO, the Company’s broker-dealer subsidiary, reports changes

Page 52 of 86

in fair value of marketable securities through current period earnings due to specialized accounting practices related to investments by broker-dealers. The Company records its investments in funds sponsored by LSV on the accompanying Consolidated Balance Sheets at fair value. Unrealized gains and losses from the change in fair value of these securities are recognized in current period earnings. The specific identification method is used to compute the realized gains and losses on all of the Company’s marketable securities (See Note 5).

The Company evaluates the realizable value of its marketable securities on a quarterly basis. In the event that the carrying value of an investment exceeds its fair value and the decline in value is determined to be other-than-temporary, an impairment charge is recorded and a new cost basis for the investment is established. Some of the factors considered in determining other-than-temporary impairment for equity securities include, but are not limited to, significant or prolonged declines in the fair value of the investments, the Company’s ability and intent to retain the investment for a period sufficient to allow the value to recover, and the financial condition of the investment. Some of the factors considered in determining other-than-temporary impairment for debt securities include, but are not limited to, the intent of management to sell the security, the likelihood that the Company will be required to sell the security before recovering its cost, and management’s expectation to recover the entire amortized cost basis of the security even if there is no intent to sell the security. The Company did not recognize any impairment charges related to its marketable securities in 2018, 2017 or 2016.

Fair Value of Financial Instruments

Fair value is defined as the exchange price that would be received for an asset or paid to transfer a liability (an exit price) in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants on the measurement date. The fair value hierarchy requires an entity to maximize the use of observable inputs and minimize the use of unobservable inputs when measuring fair value. The fair value hierarchy describes three levels of inputs that may be used by the Company to measure fair value:

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

Level 2 – Observable inputs other than Level 1 prices, such as quoted prices for similar assets, quoted prices in markets that are not active, or other inputs that are observable or can be corroborated by observable market data for substantially the full term of the assets or liabilities. Level 2 financial assets consist of Government National Mortgage Association (GNMA) mortgage-backed securities, Federal Home Loan Bank (FHLB) and other U.S. government agency short-term notes. The investments in GNMA mortgage-backed securities were purchased for the sole purpose of satisfying applicable regulatory requirements imposed on our wholly-owned limited purpose federal thrift subsidiary, SPTC. The investments in FHLB and other U.S. government agency short-term notes were purchased as part of a cash management program requiring only short term, top-tier investment grade government and corporate securities.

Level 3 – Unobservable inputs that are supported by little or no market activity and that are significant to the fair value of the assets or liabilities. Level 3 assets and liabilities include financial instruments whose value is determined using pricing models, or similar techniques, as well as instruments for which the determination of fair value requires significant judgment by management. The Company had no Level 3 financial assets at December 31, 2018 or 2017 that were required to be measured at fair value on a recurring basis. The Company's Level 3 financial liabilities at December 31, 2018 consist entirely of an estimated contingent consideration resulting from the Company's acquisition of Huntington Steele, LLC (See Note 14). The Company had no Level 3 financial liabilities as of December 31, 2017 that were required to be measured at fair value on a recurring basis.

The fair value of an asset or liability may include inputs from more than one level in the fair value hierarchy. The lowest level of significant inputs used to value the asset or liability determines which level the asset or liability is classified in its entirety. Transfers between levels of the fair value hierarchy are reported at fair value as of the beginning of the period in which the transfers occur.

See Note 4 for information on related disclosures regarding fair value measurements.

Capitalized Software

Costs incurred for the development of internal use software to be offered in a hosting arrangement is capitalized during the development stage of the software application. These costs include direct external and internal costs to design the software configuration and interfaces, coding, installation, and testing. Costs incurred during the preliminary and post-implementation stages of the software application are expensed as incurred. Costs associated with significant enhancements to a software application are capitalized while costs incurred to maintain existing software applications are expensed as incurred. The capitalization of software development costs requires considerable judgment by management with respect to certain external factors, including, but not limited to, technological and economic feasibility, and estimated economic life. Amortization of capitalized software development costs begins when the product is ready for its intended use. Capitalized software development

Page 53 of 86

costs are amortized on a product-by-product basis using the straight-line method over the estimated economic life of the product or enhancement.

The Company capitalized $44,221, $61,043 and $50,392 of software development costs during 2018, 2017 and 2016, respectively. The Company's capitalized software development costs primarily relate to the further development of the SEI Wealth Platform^SM(SWP). The Company capitalized $43,376, $51,353 and $39,785 of software development costs for significant enhancements to SWP during 2018, 2017 and 2016, respectively. As of December 31, 2018, the net book value of SWP was $288,666. The net book value includes $42,238 of capitalized software development costs in-progress associated with future releases.

Management continually reassesses the estimated useful life of SWP and any change in management’s estimate could result in the remaining amortization expense to be accelerated or spread out over a longer period. During the fourth quarter 2017, the Company adjusted the remaining useful life of certain components and functionality of SWP that were placed into service during the past several years. The adjustment resulted in a decrease to the Company's amortization expense of $4,347 and an increase to the Company's net income of $3,156, or $0.02 diluted earnings per share, in 2017. As of December 31, 2018, SWP has a weighted average remaining life of 8.5 years. Amortization expense for SWP was $39,917, $46,505 and $45,047 in 2018, 2017 and 2016, respectively, and is included in Amortization expense on the accompanying Consolidated Statements of Operations.

The Company also capitalized $845, $9,690 and $10,607 of software development costs during 2018, 2017 and 2016, respectively, related to an application for the Investment Managers segment. The application was placed into service during the first quarter 2018 with an estimated useful life of 5 years. The net book value of the application at December 31, 2018 was $20,834. Amortization expense for the application was $5,209 during 2018 and is included in Amortization expense on the accompanying Consolidated Statements of Operations.

The Company currently expects to recognize amortization expense related to all capitalized software development costs placed into service as of December 31, 2018 each year from 2019 through 2023 as follows:



2019	$	46,608
2020	46,608
2021	46,330
2022	31,817
2023	13,145

The Company evaluates the carrying value of capitalized software development costs when circumstances indicate the carrying value may not be recoverable. The review of capitalized software development costs for impairment requires significant assumptions about operating strategies, underlying technologies utilized, and external market factors. External market factors include, but are not limited to, expected levels of competition, barriers to entry by potential competitors, stability in the target market and governmental regulations. The Company did not recognize any impairment charges related to its capitalized software development costs in 2018, 2017 or 2016.

Business Combinations

The Company accounts for business combinations in accordance with Accounting Standards Codification Topic 805, Business Combinations (ASC 805). ASC 805 establishes principles and requirements for recognizing the total consideration transferred, assets acquired and liabilities assumed in a business combination. ASC 805 also provides guidance for recognizing and measuring goodwill acquired in a business combination and requires the acquirer to disclose information needed to evaluate and understand the financial impact of the business combination. The Company recognizes assets and liabilities acquired at their estimated fair values. Management uses judgment to identify the acquired assets and liabilities assumed; estimate the fair value of these assets and liabilities; estimate the useful life of the assets; and assess the appropriate method for recognizing depreciation or amortization expense over the estimated useful life of the assets.

Goodwill and Other Intangible Assets

The Company reviews long-lived assets and identifiable definite-lived intangible assets for impairment at least annually or whenever events or changes in circumstances indicate that the carrying amount of these assets may not be recoverable. For purposes of recognizing and measuring an impairment loss, a long-lived asset is grouped with other assets and liabilities at the lowest level for which identifiable cash flows are largely independent.

Identifiable definite-lived intangible assets on the Company’s Consolidated Balance Sheet are amortized on a straight-line basis according to their estimated useful lives. Goodwill is not amortized but is reviewed for impairment annually or more frequently if an event occurs or circumstances change that would more likely than not reduce the fair value of a reporting unit below its carrying amount. Current guidance require that a two-step, fair value based test be performed to assess goodwill for impairment. In the first step, the fair value of each reporting unit is compared with its carrying value, including goodwill. If the

Page 54 of 86

fair value exceeds the carrying value, goodwill is not impaired and no further testing is performed. The second step is performed if the carrying value exceeds the fair value. The second step requires an allocation of fair value to the individual assets and liabilities using a purchase price allocation in order to determine the implied fair value of goodwill. If the implied fair value of goodwill is less than the carrying amount, an impairment loss is recognized. The Company did not recognize any impairment charges related to its goodwill or other intangible assets in 2018 or 2017.

Income Taxes

The Company applies the asset and liability approach to account for income taxes whereby deferred tax assets and liabilities are recognized for the future tax consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases. Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled.

Foreign Currency Translation

The assets and liabilities and results of operations of the Company’s foreign subsidiaries are measured using the foreign subsidiary’s local currency as the functional currency. Assets and liabilities have been translated into U.S. dollars using the rates of exchange at the balance sheet dates. The results of operations have been translated into U.S. dollars at average exchange rates prevailing during the period. The resulting translation gain and loss adjustments are recorded as a separate component of comprehensive income.

Transaction gains and losses from exchange rate fluctuations are included in the results of operations in the periods in which they occur. There were no material gains or losses from exchange rate fluctuations in 2018, 2017 or 2016.

Earnings Per Common Share

Basic earnings per common share is computed by dividing net income attributable to SEI Investments common shareholders by the weighted average number of common shares outstanding during the period. Diluted earnings per common share is computed by dividing net income attributable to SEI Investments common shareholders by the combination of the weighted average number of common shares outstanding and the dilutive potential common shares, such as stock options, outstanding during the period.

The calculations of basic and diluted earnings per share for 2018, 2017 and 2016 are:



	2018		2017		2016
Net income	$	505,868	$	404,389	$	333,817
Shares used to compute basic earnings per common share	156,579,000		158,177,000		161,350,000
Dilutive effect of stock options	4,653,000		4,092,000		3,081,000
Shares used to compute diluted earnings per common share	161,232,000		162,269,000		164,431,000
Basic earnings per common share	$	3.23	$	2.56	$	2.07
Diluted earnings per common share	$	3.14	$	2.49	$	2.03

Employee stock options to purchase approximately 6,224,000, 5,196,000 and 10,632,000 shares of common stock, with an average exercise price per share of $53.60, $45.49 and $35.02, were outstanding during 2018, 2017 and 2016, respectively, but not included in the computation of diluted earnings per common share because either the performance conditions have not been satisfied or would have been satisfied if the reporting date was the end of the contingency period or the option’s exercise price was greater than the average market price of the Company’s common stock and the effect on diluted earnings per common share would have been anti-dilutive (See Note 7).

Stock-Based Compensation

Stock-based compensation cost is measured at the grant date based on the fair value of the award and is recognized as expense over the requisite service period, which is the vesting period. The amount of stock-based compensation expense that is recognized in a given period is dependent upon management’s estimate of when the vesting targets are expected to be achieved. If this estimate proves to be inaccurate, the remaining amount of stock-based compensation expense could be accelerated, spread out over a longer period, or reversed (See Note 7).

The Company adopted ASU 2016-09, Improvements to Employee Share-Based Payment Accounting (ASU 2016-09) during 2017. As required by ASU 2016-09, excess tax benefits recognized on stock-based compensation expense are reflected in the accompanying Consolidated Statements of Operations as a component of the provision for income taxes effective January 1, 2017 (See Note 11).

New Accounting Pronouncements

The new standard provides a number of optional practical expedients in transition. The Company elected the package of practical expedients which permits the Company to not reassess under the new standard its prior conclusions about lease identification, lease classification and initial direct costs. The Company did not elect the hindsight practical expedient in determining its lease terms.

As part of its project plan’s preliminary assessment and design implementation phases for the adoption of ASU 2016-02, the Company has adopted implementation controls that allow it to properly and timely adopt ASU 2016-02 on the effective date. The Company is finalizing its assessment of the adoption of ASU 2016-02. The Company expects the most significant effects will relate to the recognition of right-of-use assets and lease liabilities on the balance sheet for office space and certain office equipment and providing significant new disclosures about leasing arrangements. The Company owns its corporate headquarters and leases office space in other locations. The Company has completed the process of cataloging existing lease agreements and is finalizing the right-of-use asset and lease liability which is expected to be between $50,000 and $60,000.

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

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

In June 2018, the FASB issued ASU 2018-07, Improvements to Nonemployee Share-Based Payment Accounting (ASU 2018-07) which simplifies the accounting for nonemployee share-based payment transactions. The amendments specify that Topic 718 applies to all share-based payment transactions in which a grantor acquires goods or services to be used or consumed in a grantor’s own operations by issuing share-based payment awards. ASU 2018-07 is effective for the Company beginning in the first quarter of 2019. The adoption of ASU 2018-07 will not have a material impact on the Company's 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 evaluating the impact of adopting ASU 2018-13 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 is currently evaluating the impact of adopting ASU 2018-17 on its consolidated financial statements and related disclosures.

Note 2 – Investment in Unconsolidated Affiliates

LSV Asset Management

The Company has an investment in the general partnership 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 mutual funds. As of December 31, 2018, the Company's total partnership interest in LSV was approximately 38.9 percent. The Company accounts for its interest in LSV using the equity method because of its less than 50 percent ownership. The Company’s interest in the net assets of LSV is reflected in Investment in unconsolidated affiliates on the accompanying Consolidated Balance Sheets and its interest in the earnings of LSV is reflected in Equity in earnings of unconsolidated affiliates on the accompanying Consolidated Statements of Operations.

At December 31, 2018, the Company’s total investment in LSV was $52,342. The Company’s proportionate share in the earnings of LSV was $159,791, $152,550 and $126,103 in 2018, 2017 and 2016, respectively. The Company receives partnership distributions related to the earnings of LSV on a quarterly basis. 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 received partnership distribution payments from LSV of $166,941, $143,517 and $125,224 in 2018, 2017 and 2016, respectively.

These tables contain condensed financial information of LSV:

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

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

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 Company had no Level 3 financial assets at December 31, 2018 or 2017 that were required to be measured at fair value on a recurring basis. The Company's Level 3 financial liabilities at December 31, 2018 consist entirely of the estimated contingent consideration of $12,120 resulting from an acquisition (See Note 14). 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. The Company had no Level 3 financial liabilities as of December 31, 2017 that were required to be measured at fair value on a recurring basis.There were no transfers of financial assets between levels within the fair value hierarchy during 2018.

Valuation of GNMA and Other U.S. Government Agency Securities

All of the Company's investments in GNMA, FHLB and other U.S. government agency securities are held in accounts at well-established financial institutions. The Company's selection of a financial institution for the purpose of purchasing securities considered a number of various factors including, but not limited to, securities pricing policies and procedures utilized by that financial institution. Each financial institution utilizes the services of independent pricing vendors. These vendors utilize evaluated and industry accepted pricing models that vary by asset class and incorporate available trade, bid and other market information to determine the fair value of the securities. The market inputs, listed in approximate order of priority, include: benchmark yields, reported trade, broker/dealer quotes, issuer spreads, two-sided markets, benchmark securities, bids, offers and reference data. The Company evaluated the information regarding the pricing methodologies and processes utilized by the independent pricing vendors during the selection process of the financial institution. The Company analyzed this information for the purpose of classifying the securities into the appropriate level within the fair value hierarchy and to ensure that each pricing model for each asset class provided the fair value of those specific securities in accordance with generally accepted accounting principles. The Company continually monitors the price of each security for any unanticipated deviations from the previously quoted price. In the event of any significant unanticipated deviations in a security's price, additional analysis is conducted. The Company's investments in GNMA, FHLB and other U.S. government agency securities have been recorded at the prices provided by the independent pricing vendor without adjustment.

Note 6 – Line of Credit

The Company has a five-year $300,000 Credit Agreement (the Credit Facility) with Wells Fargo Bank, National Association (Wells Fargo) and a syndicate of other lenders. The Credit Facility is scheduled to expire in June 2021, at which time any aggregate principal amount of loans outstanding becomes payable in full. Any borrowings made under the Credit Facility will accrue interest at rates that, at the Company's option, are based on a base rate (the Base Rate) plus a premium that can range from 0.25 percent to 1.00 percent or the London InterBank Offered Rate (LIBOR) plus a premium that can range

Page 60 of 86

from 1.25 percent to 2.00 percent depending on the Company’s Leverage Ratio (a ratio of consolidated indebtedness to consolidated EBITDA for the four preceding fiscal quarters, all as defined in the related agreement). The Base Rate is defined as the highest of a) the Federal Funds Rate, as published by the Federal Reserve Bank of New York, plus 0.50 percent, b) the prime commercial lending rate of Wells Fargo, c) the applicable LIBOR plus 1.00 percent, or d) 0 percent. The Company also pays quarterly commitment fees based on the unused portion of the Credit Facility. The quarterly fees for the Credit Facility can range from 0.15 percent of the amount of the unused portion to 0.30 percent, depending on the Company’s Leverage Ratio. Certain wholly-owned subsidiaries of the Company have guaranteed the obligations of the Company under the agreement. The aggregate amount of the Credit Facility may be increased by an additional $100,000 under certain conditions set forth in the agreement. 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 1.250 percent plus a fronting fee of 0.175 percent 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, or to incur liens, as defined in the agreement. In the event of a default under the Credit Facility, the Company would also be restricted from paying dividends on, or repurchasing, its common stock without the approval of the lenders. None of the covenants of the Credit Facility negatively affect the Company’s liquidity or capital resources. Upon the occurrence of certain financial or economic events, significant corporate events, or certain other events of default constituting an event of default under the Credit Facility, all loans outstanding may be declared immediately due and payable and all commitments under the agreement may be terminated.

In July 2017, the Company borrowed $40,000 under the Credit Facility for the funding of the acquisition of Archway (See Note 14). The Company made principal payments of $30,000 and $10,000 during 2018 and 2017, respectively, to fully repay the outstanding balance of the Credit Facility.

As of December 31, 2018, the Company had outstanding letters of credit of $13,813 under the Credit Facility. These letters of credit were issued primarily for the expansion of the Company's headquarters and are scheduled to expire in 2019. The amount of the Credit Facility that is available for general corporate purposes as of December 31, 2018 was $286,187. The Company was in compliance with all covenants of the Credit Facility during 2018.

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

The Company incurred $645, $781 and $531 in interest charges and commitment fees relating to its line of credit during 2018, 2017 and 2016, respectively, which are reflected in Interest expense on the accompanying Consolidated Statements of Operations. The weighted average interest rate applied to the outstanding balance of the Credit Facility during 2018 was 2.93 percent.

Note 7 – Shareholders’ Equity

Stock-Based Compensation

The Company's active equity compensation plan, the 2014 Omnibus Equity Compensation Plan (the 2014 Plan), is the successor plan to the 2007 Equity Compensation Plan (the 2007 Plan) which was merged with and into the 2014 Plan in May 2014. The 2014 Plan provides for the grant of stock options, stock units, stock awards, stock appreciation rights, dividend equivalents and other stock-based awards.

Outstanding grants under the 2007 Plan will continue according to the terms in effect before the plan merger, but the outstanding shares will be issued or transferred under the 2014 Plan. Permitted grantees under the 2014 Plan include employees, non-employee directors and consultants who perform services for the Company. The plan is administered by the Compensation Committee of the Board of Directors of the Company. The Company has only non-qualified stock options outstanding under the 2014 Plan.

All outstanding stock options have performance-based vesting provisions that tie the vesting of stock options to the Company’s financial performance. The Company’s stock options vest at a rate of 50 percent when a specified diluted earnings per share target is achieved, and the remaining 50 percent when a second, higher-specified diluted earnings per share target is achieved. Options do not vest due to the passage of time but 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.

Page 61 of 86

The Company uses the Black-Scholes option pricing model to determine the fair value of stock options. The determination of the fair value of stock options on the date of grant using an option-pricing model is affected by the price of the Company’s common stock as well as other variables. These variables include expected stock price volatility over the term of the awards, actual and projected employee stock exercise behaviors, risk-free interest rate and expected dividends. The Company primarily uses historical data to estimate the variables used in the option-pricing model except expected volatility. The Company uses a combination of historical and implied volatility.

The weighted average fair value of the Company’s stock options granted during 2018, 2017 and 2016 were $13.04, $16.78 and $12.43, respectively, using the following assumptions:



	2018		2017		2016
Expected term (in years)	6.34		6.00		6.00
Expected volatility	25.27	%	22.58	%	25.44	%
Expected dividend yield	1.35	%	0.82	%	1.10	%
Risk-free interest rate	2.75	%	2.29	%	2.18	%

The Company recognized stock-based compensation expense in its Consolidated Financial Statements in 2018, 2017 and 2016 as follows:



	2018			2017			2016
Stock-based compensation expense	$	23,805		$	36,366		$	16,017
Less: Deferred tax benefit	(5,078		)	(7,891		)	(5,612		)
Stock-based compensation expense, net of tax	$	18,727		$	28,475		$	10,405

During 2018, 2017 and 2016, the Company revised its estimates of when some vesting targets are expected to be achieved. The changes in management’s estimates during 2018 and 2017 resulted in an increase of $1,909 and $11,206 in stock-based compensation expense in 2018 and 2017, respectively. The change in management’s estimate during 2016 was not material.

As of December 31, 2018, there was approximately 6,454,000 unvested employee stock options with an unrecognized compensation cost of $68,470 that the Company expects will vest and be expensed through 2023 with a weighted average period of 2.2 years.

Employee Stock Purchase Plan

The Company has an employee stock purchase plan that provides for offerings of common stock to eligible employees at a price equal to 85 percent of the fair market value of the stock at the end of the stock purchase period, as defined. The Company has reserved 15,600,000 shares for issuance under this plan. At December 31, 2018, 12,038,000 cumulative shares have been issued. There were no material costs incurred by the Company related to the employee stock purchase plan in 2018, 2017 and 2016.

Common Stock Buyback

The Board of Directors, under multiple authorizations, has authorized the purchase of the Company’s common stock on the open market or through private transactions. As of December 31, 2018, the Company had approximately $215,879 of authorization remaining for the purchase of common stock. The following table provides the total number of shares repurchased and the related total costs in 2018, 2017 and 2016:

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.

Rights Agreement

The Company’s Board of Directors declared a dividend distribution pursuant to a Rights Agreement (the Rights Agreement) which became effective on January 6, 2009. The Rights Agreement was not renewed and expired on January 6, 2019. The purpose of the Rights Agreement was to deter coercive or unfair takeover tactics and to prevent a person or group from acquiring control of the Company without offering a fair price to all shareholders. Under the Rights Agreement, all common shareholders would have received one Right for each common share outstanding. Each Right entitled the registered holder to purchase from the Company a unit consisting of one twenty-thousandths of a share of Series A Junior Participating Preferred Shares, $0.05 par value per share, or a combination of securities and assets of equivalent value, at a purchase price of $150.00 per unit, subject to adjustment.

Stanford Trust Company Litigation

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. No material activity has taken place since remand.

SEI Capital Accumulation Plan Litigation

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 11 – Income Taxes

The Company's foreign income is primarily earned in Canada and the Republic of Ireland.

The effective income tax rate differs from the federal income tax statutory rate due to the following:



Year Ended December 31,	2018		2017		2016
Statutory rate	21.0	%	35.0	%	35.0	%
State taxes, net of federal tax benefit	1.9		1.3		1.3
Foreign tax expense and tax rate differential	(0.1	)	(1.1	)	(0.8	)
Tax benefit from stock option exercises	(3.8	)	(3.9	)	—

Other, net	(0.3	)	(0.2	)	0.2
	17.6	%	27.4	%	34.3	%

The Company's effective income tax rate in 2018 included the new 21.0 percent corporate tax rate under the Tax Cut and Jobs Act (the Tax Act). The Tax Act also provided for a Foreign Derived Intangible Income (FDII) deduction. For 2018, the Company estimated a federal FDII benefit of $1,206. The Tax Act also repealed the Section 199 Deduction for businesses that perform domestic manufacturing and certain other production activities which had an unfavorable impact on the Company's tax rate in 2018.

The Company's effective income tax rate in 2017 included the adoption of ASU 2016-09 and the estimated impact of the Tax Act. As required by ASU 2016-09, the Company no longer records excess tax benefits from stock option exercises as an increase to additional paid in capital, but records such excess tax benefits as a reduction of income tax expense in the reporting period in which the exercises occur.

The impact to the Company's effective tax rate in 2017 from the Tax Act was a combination of a $27,153 tax benefit from the re-measurement of the Company's estimated net deferred tax liability as of December 31, 2017 based upon the new 21.0 percent corporate tax rate offset by expense of $14,743 from the preliminary estimate of the one-time transition tax relating to the impact of the deemed repatriation and withholding tax of the Company's previously undistributed foreign earnings. The net impact to the Company's tax rate in 2017 from the Tax Act was a net tax benefit of $12,410, or $0.08 diluted earnings per share. The favorable impact to the Company's effective income tax rate in 2018 from the Tax Act related to the finalization of the estimated one-time transition tax. This adjustment to the one-time transition tax represents what the Company believes is its final liability under the changes from the Tax Act.

The Tax Act also imposed a territorial rather than worldwide system which requires a one-time transition tax on the repatriation of previously deferred foreign earnings. The Company's one-time transition tax as of the filing of the Company's 2017 Federal Tax Return was $10,711. After the Company made a payment of $1,000 and its estimated tax payments relating to its 2017 tax liability, the IRS issued guidance informing taxpayers that they may not receive a refund or credit of any portion of properly applied 2017 tax payments unless and until the amount of payments exceeds the entire unpaid 2017 repatriation tax liability, including all amounts to be paid in installments in subsequent years. In accordance with this guidance, the Company was required to apply $8,908 from an overpayment of federal taxes against the transition tax payable during 2018. The remaining amount payable related to the transition tax of $803 is included in Long-term income taxes payable on the accompanying Consolidated Balance Sheet.

Deferred income taxes for 2018 and 2017 reflect the impact of temporary differences between the amount of assets and liabilities for financial reporting purposes and such amounts as measured by tax laws and regulations. Significant components of our deferred tax assets and liabilities at December 31, 2018 and 2017 are as follows:



	2018			2017
Deferred Tax Assets:
Stock-based compensation expense	$	24,125		$	24,725
Foreign and state net operating loss carryforward and FTC	74,358			71,236
Basis differences in investments	4,118			4,191
Federal benefit of state tax deduction for uncertain tax positions	1,882			1,918
Revenue and expense recognized in different periods for financial reporting and income tax purposes	1,657			2,631
Other assets	1,049			273
Total deferred income tax assets	107,189			104,974
Less: valuation allowance	(72,316		)	(68,469		)
Net deferred income tax assets	$	34,873		$	36,505

Deferred Tax Liabilities:
Capitalized software currently deductible for tax purposes, net of amortization	$	(71,067	)	$	(70,575	)
Difference in financial reporting and income tax depreciation methods	(6,545		)	(3,182		)
Difference between book and tax basis of other assets	(4,429		)	(3,549		)
Goodwill and other intangibles	(1,823		)	(1,001		)
Foreign Dividend Withholding Tax	(312		)	(3,199		)
Capitalized contract costs	(5,490		)	—
Other liabilities	(960		)	(704		)
Total deferred income tax liabilities	$	(90,626	)	$	(82,210	)
Net deferred income tax liabilities	$	(55,753	)	$	(45,705	)

The valuation allowances against deferred tax assets at December 31, 2018 and 2017 are related to state net operating losses from certain domestic subsidiaries, foreign net operating losses from certain foreign subsidiaries and The Tax Act restriction of use of the foreign tax credit placed by The Tax Act. Certain state and foreign tax statutes significantly limit the utilization of net operating losses for domestic and foreign subsidiaries. Furthermore, these net operating losses cannot be used to offset the net income of other subsidiaries.

The Company recognizes uncertain tax positions in accordance with the applicable accounting guidance and adjusts these liabilities when management’s judgment changes as a result of the evaluation of new information not previously available. Due to the complexity of some of these uncertainties, the ultimate resolution may result in a payment that is materially different from our current estimate of the tax liabilities. The Company’s total unrecognized tax benefit, not including interest and penalties, as of December 31, 2018 was $14,367, of which $13,774 would affect the effective tax rate if the Company were to recognize the tax benefit. The gross amount of uncertain tax liability of $3,131 is expected to be paid within one year is netted against the current payable account while the remaining amount of $12,525 is included in Other long-term liabilities on the accompanying Consolidated Balance Sheets. During the year ended December 31, 2018, the Company recognized $2,621 of previously unrecognized tax benefits relating to the lapse of the statute of limitation.

The Company files a consolidated federal income tax return and separate income tax returns with various states. Certain subsidiaries of the Company file tax returns in foreign jurisdictions. 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.

Page 68 of 86

A reconciliation of the beginning and ending amount of unrecognized tax benefit is as follows:



	2018			2017			2016
Balance as of January 1	$	14,480		$	17,287		$	14,517
Tax positions related to current year:
Gross additions	2,446			3,180			3,756
Tax positions related to prior years:
Gross additions	340			211			1,762
Settlements	(278		)	(352		)	(378		)
Lapses on statute of limitations	(2,621		)	(5,846		)	(2,370		)
Balance as of December 31	$	14,367		$	14,480		$	17,287

The above reconciliation of the gross unrecognized tax benefit will differ from the amount which would affect the effective tax rate because of the recognition of the federal and state tax benefits.

The Company classifies all interest and penalties as income tax expense. The Company has recorded $1,289, $1,175 and $1,227 in liabilities for tax-related interest and penalties in 2018, 2017 and 2016, respectively.

The Company estimates it will recognize $3,131 of unrecognized tax benefits within the next twelve months due to lapses on the statute of limitation.

The Company includes its direct and indirect subsidiaries in its U.S. consolidated federal income tax return. The Company’s tax sharing allocation agreement provides that any subsidiary having taxable income will pay a tax liability equivalent to what that subsidiary would have paid if it filed a separate income tax return. If the separately calculated federal income tax provision for any subsidiary results in a tax loss, the current benefit resulting from such loss, to the extent utilizable on a separate return basis, is accrued and paid to that subsidiary.

Note 14 – Business Acquisitions

Huntington Steele

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, to enhance the Company's business development and research efforts in an additional geographic region. Under the acquisition method of accounting, the total purchase price was allocated to Huntington Steele's net tangible and intangible assets based upon their estimated fair values as of April 2, 2018. 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 over the next five years. The current portion of the contingent purchase price of $430 is included in Accrued liabilities on the accompanying Balance Sheet. The long-term portion of the contingent consideration of $11,690 is included in Other long-term liabilities on the accompanying Balance Sheet.

The purchase price allocation for the Huntington Steele acquisition is as follows:

Archway

On July 3, 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, from Keystone International Holdings, Inc. With this acquisition, the Company expands its position in the single and multi-family office services market by diversifying its technology and operating solutions.

Under the acquisition method of accounting, the total purchase price was allocated to Archway's net tangible and intangible assets based upon their estimated fair values as of July 3, 2017. The total purchase price for Archway was $81,635 in cash consideration with up to an additional $8,000 payable to the seller as a contingent purchase price with respect to two one-year periods ended December 31, 2017 and 2018 depending upon whether Archway achieved specified financial measures during such periods. The fair value of the contingent consideration was estimated to be $4,800 on the acquisition date. Archway did not attain the specified financial measure for the periods ended December 31, 2017 or December 31, 2018. As a result, as of December 31, 2017, the Company reversed the value allocated to the contingent consideration established at the acquisition date. Additionally, the Company recognized a liability for post-acquisition obligations to the members of Archway. The net adjustment of $3,800 was recorded as a reduction in expense and is reflected in Facilities, supplies and other costs on the accompanying Consolidated Statement of Operations in 2017. At December 31, 2018, the Company reversed the liability for the post-acquisition obligations to the members of Archway as the specified financial measure was not achieved.

The Company acquired $1,401 in cash during the acquisition, resulting in $80,234 net cash paid for Archway. According to the terms of the purchase agreement, a portion of the purchase price was placed into escrow to indemnify the Company of any pre-acquisition damages. As of December 31, 2018, the balance available in escrow was $8,000. During January 2019, the entire amount placed into escrow was released to the seller. As of January 31, 2019, the Company has no further obligation related to the acquisition of Archway.

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. The client is billed directly on a monthly basis. Revenues are recognized in Information processing and software servicing fees on the accompanying Consolidated Statements of Operations.

Professional services fees - Revenues associated with the business services migration for investment processing clients of the Private Banks segment and investment operations clients of the Investment Managers segment. In addition, Professional services include other services such as business transformation consulting. Typically, fees are stated as a contractual fixed fee. The client is billed directly and fees are collected according to the terms of the agreement.

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 either: contracts with an original term of one year or less; contracts for which the Company recognizes revenue at the amount to which it has the right to invoice for services performed; or contracts that are based on the value of assets under management or administration.

Deferred Contract Costs

Deferred contract costs, which primarily consist of deferred sales commissions, were $24,007 as of December 31, 2018. The Company recorded a cumulative effect adjustment on January 1, 2018 of $18,641 associated with the capitalization of contract costs upon the adoption of ASC 606 (See Note 1). The Company deferred expenses related to contract costs of $8,122 during 2018. Amortization expense related to deferred contract costs were $2,756 during 2018 and is included in Compensation, benefits and other personnel on the accompanying Consolidated Statements of Operations. There was no impairment loss in relation to deferred contract costs during 2018.

Item 9A. Controls and Procedures.

Conclusion Regarding the Effectiveness of Disclosure Controls and Procedures

Under the supervision and with the participation of our management, including our Chief Executive Officer and Chief Financial Officer, we conducted an evaluation of the effectiveness of our disclosure controls and procedures, as such term is defined under Rule 13a-15(e) promulgated under the Securities Exchange Act of 1934, as amended (the Exchange Act), as of the end of the period covered by this report. Based on this evaluation, our Chief Executive Officer and Chief Financial Officer concluded that our disclosure controls and procedures are effective as of the end of the period covered by this annual report to provide reasonable assurance that the information required to be disclosed by us in reports filed under the Exchange Act is recorded, processed, summarized, and reported within the time periods specified in the SEC’s rules and forms. Disclosure controls and procedures include, without limitation, controls and procedures designed to ensure that information required to be disclosed by an issuer in the reports that it files or submits under the 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.

Management’s Report on Internal Control over Financial Reporting

Our management is responsible for establishing and maintaining adequate internal control over financial reporting, as such term is defined in Exchange Act Rule 13a-15(f). Under the supervision and with the participation of our management, including our Chief Executive Officer and Chief Financial Officer, we conducted an evaluation of the effectiveness of our internal control over financial reporting based on the framework in Internal Control – Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission. Based on our evaluation under the framework in Internal Control – Integrated Framework (2013), our management concluded that our internal control over financial reporting was effective as of December 31, 2018.

The effectiveness of our internal control over financial reporting as of December 31, 2018 has been audited by KPMG LLP, an independent registered public accounting firm, as stated in their report which is included herein.

Changes in Internal Control over Financial Reporting

No change in our internal control over financial reporting occurred during the quarter ended December 31, 2018 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 contracts and properly assessed the impact of the new accounting standard related to revenue recognition on our consolidated financial statements to facilitate the adoption of this standard on January 1, 2018 as well as the ongoing accounting under the new standard. There were no significant changes to our internal control over financial reporting during 2018 as a result of the ongoing accounting under the new accounting standard.

The 2014 Omnibus Equity Compensation Plan:

On March 19, 2014, the Board of Directors adopted the 2014 Omnibus Equity Compensation Plan (the 2014 Plan), and the Company’s shareholders approved the adoption of the 2014 Plan on May 21, 2014 (the Effective Date). The 2014 Plan replaced the 2007 Equity Compensation Plan (The 2007 Plan). The 2007 Plan has been merged with and into the 2014 Plan as of the Effective Date. Outstanding grants under the 2007 Plan will continue according to the terms in effect before the plan merger, but the outstanding shares with respect to those outstanding grants will be issued or transferred under the 2014 Plan. No additional grants shall be made after the Effective Date under the 2007 Plan.

The 2014 Plan provides for grants of stock options (incentive stock options and nonqualified stock options), stock units, stock awards, stock appreciation rights (SARs), dividend equivalents and other stock-based awards to all employees (including employees who are also directors) of the Company or its subsidiaries, consultants who perform valuable services to the Company or its subsidiaries and members of the Board of Directors who are not employees of the Company. The Company has only granted nonqualified stock options under the 2014 Plan.

The 2014 Plan is administered and interpreted by the Compensation Committee (the Committee) or another committee appointed by our Board of Directors; however, the Board of Directors or its delegate will administer and interpret all grants under the 2014 Plan to non-employee directors. The Committee has the authority to (i) determine the individuals to whom grants will be made under the 2014 Plan, (ii) determine the type, size and terms and conditions of the grants, (iii) determine the time when grants will be made and the duration of any applicable exercise or restriction period, including the criteria for exercisability and the acceleration of exercisability, (iv) amend the terms and conditions of any previously issued grant, and (v) deal with any other matters arising under the 2014 Plan.

Options granted under the 2014 Plan may be “incentive stock options,” which are intended to qualify within the meaning of Section 422 of the Internal Revenue Code, and “nonqualified stock options” which are not intended to so qualify. Options are granted under the 2014 Plan with an exercise price equal to or greater than the fair market value of the Company’s common stock on the date of grant and the term of which may not exceed ten years from the date of grant. The vesting period for options commences on the date of grant, or upon the achievement of such vesting requirements, and ends on such date as is determined in each case by the Committee, in its sole discretion, which is specified in the grant agreement. Options may be exercised only while the participant is actively employed by or actively providing service to the Company unless the Committee provides for a period after such employment or service in which the option may be exercised. The Committee may only grant incentive stock options to employees of the Company or its subsidiaries.

The Committee may grant SARs to anyone eligible to participate in the 2014 Plan. Upon exercise of a SAR, the participant will receive an amount equal to the excess of the fair market value of the Company’s common stock on the date of exercise over the base amount set forth in the grant agreement. Such payment to the participant will be in cash, in shares of common stock, or in a combination of cash and shares of common stock as determined by the Committee. The Committee

Page 80 of 86

will determine the period when SARs vest and become exercisable, the base amount of the SARs, and whether SARs will be granted in connection with, or independently of, any options. SARs may be exercised only while the participant is actively employed by or actively providing service to the Company unless the Committee provides for a period after such employment or service in which the option may be exercised.

The Committee may grant stock units to anyone eligible to participate in the 2014 Plan. A stock unit is a phantom unit that represents the right to receive a share of common stock or an amount based on the value of a share of the Company’s common stock. The Committee will determine the number of stock units that a participant will receive and the terms and conditions applicable to such stock units as specified in the grant agreement. The Committee may grant stock units that are payable at the end of a specified vesting period or if specified performance goals or other conditions are met, or under other circumstances. Such payment to the participant will be in cash, in shares of common stock, or in a combination of cash and shares of common stock. The Committee will determine the period and conditions when stock units vest. The Committee will determine in the grant agreement under what circumstances a participant may retain stock units if after employment or service with the Company prior to the vesting of any stock units and the circumstances under which a participant will forfeit stock units.

The Committee may grant dividend equivalents in connection with stock units, under such terms and conditions the Committee deems appropriate. Dividend equivalents may be paid as and when the underlying stock units are paid, or may be deferred. The dividend equivalent amount with respect to a stock unit is determined by multiplying the number of shares of the Company’s common stock subject to the stock unit by the per share cash dividend, or the per share fair market value for non-cash dividends, paid by the Company with respect to a dividend record date. Dividend equivalents may be accrued as a cash obligation, or may be converted to additional stock units, and deferred dividend equivalents may accrue interest, all as determined by the Committee. The Company may provide that dividend equivalents are payable based on the achievement of specific performance goals. Dividend equivalents may be paid in cash, shares of common stock, or in a combination of the two, as determined by the Committee.

The Committee may grant stock awards to anyone eligible to participate in the 2014 Plan. A stock award is a grant of shares of the Company’s common stock, which may be subject to restrictions. The Committee will determine whether a stock award will be granted, the number of shares that will be subject to such award, when and how restrictions, if any, will lapse, and whether a purchase price must be paid for the shares subject to the award. The Committee will determine the period and conditions when stock awards vest. The Committee will determine in the grant agreement under what circumstances a participant may retain stock awards if after employment or service with the Company prior to the vesting of any stock awards and the circumstances under which a participant will forfeit stock awards.

For each share of common stock that is actually issued or transferred pursuant to a grant, other than a stock option or SAR, and which is settled by the issuance of common stock, will count as three shares against the share limits. Each share of common stock that is actually issued or transferred pursuant to a stock option or SAR will count as one share against the share limits. If and to the extent grants under the 2014 Plan (including stock options granted under the 2007 Plan) terminate, expire, or are canceled, forfeited, exchanged, or surrendered without having been exercised, the shares subject to such grants will again be available for purposes of the 2014 Plan, taking into account the ratios described above.

If there is any change in the number or kind of shares of common stock outstanding by reason of a stock dividend, spin-off, recapitalization, stock split, or combination or exchange of shares, by reason of a merger, reorganization or consolidation, by reason of a recapitalization or change in par value or by reason of any other extraordinary or unusual event affecting the outstanding common stock as a class without the Company’s receipt of consideration, or if the value of outstanding shares of common stock is substantially reduced as a result of a spin-off or the Company’s payment of an extraordinary dividend or distribution, the maximum number of shares of common stock available for issuance under the 2014 Plan, the maximum number of shares of common stock which any individual may receive pursuant to grants in any year, the kind and number of shares covered by outstanding grants, the kind and number of shares issued and to be issued under the 2014 Plan, and the price per share or the applicable market value of such grants shall be appropriately adjusted by the Committee, in such manner as the Committee deems appropriate, to reflect any increase or decrease in the number of, or change in the kind or value of, the issued shares of common stock to preclude, to the extent practicable, the enlargement or dilution of rights and benefits under the 2014 Plan and such outstanding grants.

Unless otherwise set forth in the grant agreement, with respect to stock options, stock units, stock awards, stock appreciation rights or other stock based awards, if (a) a change of control occurs and (b) during the period commencing on the date of the change of control and ending on the date that is 24 months following the change of control, the participant’s employment or service is terminated (i) by the Company or its subsidiaries without “cause” (as defined in the 2014 Plan), (ii) by the participant for “good reason” (as defined in the 2014 Plan), (iii) by the Company or its subsidiaries on account of the participant’s Disability (as defined in the 2014 Plan), or (iv) on account of the participant’s death, then all outstanding stock options and stock appreciation rights will vest and become exercisable and all other outstanding grants will vest and all restrictions pertaining to such other grants will lapse and have no further effect.

Page 81 of 86

The Board of Directors may amend or terminate the 2014 Plan at any time, subject to shareholder approval. No grants may be issued under the 2014 Plan after May 20, 2024.

As of December 31, 2018, options to acquire 15,813,180 shares were outstanding under the 2014 Plan, out of a total of 46,934,334 shares of common stock reserved for issuance under the 2014 Plan. The 2014 Plan authorizes the issuance of an additional 30,000,000 new shares of common stock. This is in addition to 16,235,712 shares of common stock which were subject to outstanding grants under the 2007 Plan as of the Effective Date and 698,622 shares of common stock which remained available for issuance or transfer under the 2007 Plan but not subject to previously exercised, vested or paid grants as of the Effective Date. A total of 21,774,756 shares of common stock remain available for issuance under the 2014 Plan for future grants.

The 2007 Equity Compensation Plan:

On April 3, 2007, the Board of Directors adopted the 2007 Equity Compensation Plan (the 2007 Plan), and the Company’s shareholders approved the adoption of the 2007 Plan on May 23, 2007. The 2007 Plan provided for grants of stock options (incentive stock options and nonqualified stock options) and stock appreciation rights (SARs) to all employees (including employees who are also directors) of the Company or its subsidiaries, consultants who perform valuable services to the Company or its subsidiaries and members of the Board of Directors who are not employees of the Company. The Company did not grant any incentive stock options or stock appreciation rights under the 2007 Plan.

The 2007 Plan has been merged with and into the 2014 Plan as of May 21, 2014. Outstanding grants under the 2007 Plan will continue according to the terms in effect before the plan merger, but the outstanding shares with respect to those outstanding grants will be issued or transferred under the 2014 Plan. No additional grants shall be made after May 21, 2014 under the 2007 Plan.

Michael Peterson

[Residence Address Omitted]

Dear Michael:

On behalf of SEI, we are pleased to extend this offer of employment to you to perform the role of Executive Vice President and General Counsel. In this role, you will be responsible for the leadership of the legal and compliance functions, and provide counsel to the Board of Directors and its committees. As a member of the senior management team, you will be a member of the EPS committee reporting directly to the Chief Executive Officer and Board of Directors.

The starting salary will be approximately $20,192.30 bi-weekly, which is $525,000.00 when annualized. Should you accept this offer, you will begin work as a full-time exempt employee on 6/18/2018. All new hires are required to attend New Employee Orientation. On your start date, join us in the Rotunda (Building 100) by 8:30 am where an SEI representative will meet you.

You will also receive a one-time sign-on bonus of $250,000.00, provided we receive the signed Employee Sign-On Bonus Repayment Agreement outlining the terms of your sign-on bonus, attached to this letter.

In addition, you will also be eligible to participate in SEI’s Incentive Compensation Plan. Incentive Compensation awards are subject to executive management’s discretion and approval by the Compensation Committee of the Board of Directors. Based on a specified target amount, the actual payment is adjusted based primarily on achievement of Company and Unit goals, and Team performance. Your annual Incentive Compensation target will be $750,000.00. For the 6 month period following your start date, $250,000 of your Incentive Compensation target will be guaranteed, and will be payable over 6 month period after employment starts. This non-recoverable draw ends after 6 months and reduces IC award in 2018 for draw payments made in 2018.

In order to provide you with financial incentives, your compensation program also includes eligibility to participate in the Company’s Stock Option Program. You will be granted 200,000 “Signing” options in this program subject to approval by the SEI Compensation Committee and ratification of such approval by the SEI full board of directors. The Company will grant an additional 100,000 shares over the first two years, in 50,000 share increments, bringing total options to 300,000 by the end of year two. The vesting provisions for such options will be the same as those applicable to the December 2017 option grants made generally to employees (except as described below), and the exercise price will be the closing price of Company common stock on the date of commencement of your employment, or if later, approval of the grant by the Compensation Committee and ratification by the Board. If terminated without cause during the 60 months following commencement of employment, you will be paid two times (2x) salary plus bonus, and unvested “signing” options will vest in full. If terminated without cause, the option exercise period for the “signing” option grant will be one year from termination (rather than the normal 90 day period). Upon your death, or disability, or termination without cause, the “signing” option grant vests in full.

In addition to salary, incentive compensation and draw, you will be eligible to participate in other benefits as set forth in Schedule A hereto.

SEI provides a comprehensive benefits program for full-time employees. When you join us, you will be asked to make some important decisions based on your personal insurance needs. Therefore, please carefully review and evaluate the enclosed information. Selected and company-provided benefits are effective on the first of the month following one's start date. In addition, you will be eligible to receive paid time off, consistent with other EVPs holding similar responsibility.

Please note, you will be automatically enrolled in the SEI Capital Accumulation Plan, 401(k) retirement plan, with a three percent (3%) deferral rate unless you “Opt Out” or complete the enrollment process by selecting the deferral rate of your choice within the first 90 days of employment. The investment election for automatically enrolled deferrals

is in the SEI Target Date Fund designed for Plan participants in your age range. You should also be aware that once you are enrolled in the Plan you may change your investment elections or deferral percentage.

All employees of SEI are employed at-will, and either the employee or SEI is free to terminate the employee’s employment at any time, for any reason or no reason and with or without notice and with or without cause. None of these statements or documents, whether singly or combined, shall create an express or implied contract of employment for a definite period nor an express or implied contract concerning any terms or conditions of employment.

SEI retains the discretion at all times to decide whether or not to sponsor a job candidate for an appropriate temporary work visa. SEI also retains the discretion to decide whether to apply for a temporary work permit for a current employee who may wish to change temporary visa categories. All of these decisions are dependent upon the operation of the immigration laws and regulations governing the particular situation, as well as our business needs. SEI is under no obligation-legal or otherwise-to extend an offer of employment to, or to hire, any candidate who does not possess the requisite work authorization to work at SEI at the time the offer of employment is made.

This offer of employment is contingent upon the completion of a satisfactory background check. At your earliest convenience, please send the signed offer letter to [email address omitted].

You will receive a follow-up e-mail outlining all the necessary requirements which must be completed prior to your start date.

This offer of employment may also be contingent upon the accuracy of the political contribution information you provided to SEI during the hiring process in accordance with SEC Rule 206(4)-5 “Political Contributions by Certain Investment Advisers” (the “Rule”) (if applicable), and by signing below, you certify to the accuracy of your contribution history provided to SEI. You understand that once you become an employee of SEI you will be subject to applicable policies and procedures, including those which address limitations on political contributions under the Rule. Additionally, you understand that in the event that SEI discovers that the political contribution history you provided during the hiring process is inaccurate or incomplete, you will be subject to immediate termination.

All cash payments described herein are subject to reduction for federal, state, and local withholding taxes and other normal payroll deductions.

In addition, this offer of employment is contingent upon your ability to provide original evidence of identity and work authorization acceptable under the immigration and naturalization laws, in connection with the completion of an electronic Form I-9 within three (3) business days of your hire.

As a further condition of your employment, all employees are required to execute the SEI Employee Non-Disclosure and Non-Compete Agreement.

Everyone who met with you at SEI was impressed with your experience and background. We believe that this offer represents a good career opportunity for you today, with excellent potential for your continuing personal and professional development. If you have any questions or need clarification, please do not hesitate to call me at [phone number omitted]. Please initial the first page and sign below to indicate your acceptance. This offer will expire if it is not signed and returned to SEI within 7 days from the date of this letter.

Sincerely,

/s/ Jeffrey Robbins

If such deductions are not sufficient to cover all Repayment, I agree to pay SEI Investments upon written demand, the remaining balance. Any such written demand must be received by me within thirty (30) days after the effective date of Employment Termination.

ACKNOWLEDGEMENT. I acknowledge that neither this Repayment Agreement nor anything set forth herein constitutes a contract for my employment.

ATTORNEYS’ FEES.

Independent Auditors’ Report

To the Management Committee and Partners of

LSV Asset Management:

We have audited the accompanying financial statements of LSV Asset Management (the Partnership), which comprise the balance sheets as of December 31, 2018 and 2017, and the related statements of operations, changes in partners’ capital, and cash flows for each of the years in the three-year period ended December 31, 2018, and the related notes to the financial statements.

Management’s Responsibility for the Financial Statements

Management is responsible for the preparation and fair presentation of these financial statements in accordance with U.S. generally accepted accounting principles; this includes the design, implementation, and maintenance of internal control relevant to the preparation and fair presentation of financial statements that are free from material misstatement, whether due to fraud or error.

Auditors’ Responsibility

Our responsibility is to express an opinion on these financial statements based on our audits.We conducted our audits in accordance with auditing standards generally accepted in the United States of America. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free from material misstatement.

An audit involves performing procedures to obtain audit evidence about the amounts and disclosures in the financial statements. The procedures selected depend on the auditors’ judgment, including the assessment of the risks of material misstatement of the financial statements, whether due to fraud or error. In making those risk assessments, the auditor considers internal control relevant to the Partnership’s preparation and fair presentation of the financial statements in order to design audit procedures that are appropriate in the circumstances, but not for the purpose of expressing an opinion on the effectiveness of the Partnership’s internal control. Accordingly, we express no such opinion. An audit also includes evaluating the appropriateness of accounting policies used and the reasonableness of significant accounting estimates made by management, as well as evaluating the overall presentation of the financial statements.

We believe that the audit evidence we have obtained is sufficient and appropriate to provide a basis for our audit opinion.

Opinion

In our opinion, the financial statements referred to above present fairly, in all material respects, the financial position of LSV Asset Management as of December 31, 2018 and 2017, and the results of its operations and its cash flowsfor each of the years in the three-year period ended December 31, 2018 in accordance with U.S. generally accepted accounting principles.

Emphasis of Matter

As discussed in Note 2 to the financial statements, on January 1, 2018, the Partnership adopted new guidance related to revenue recognition. Our opinion is not modified with respect to this matter.

1.	Background

LSV Asset Management (“LSV” or the “Partnership”), a Delaware general partnership, is a registered investment advisor that provides management services to institutions, including pension plans and investment companies. LSV uses the Quantitative Value Analysis Method and Software to market its investment advisory services. SEI Funds, Inc. (a wholly-owned subsidiary of SEI Investments Company (“SEI”)) owns approximately 39 percent of the Partnership and the remaining portion, approximately 61 percent is owned by LSV employees and former employees. The general Partnership Agreement has been amended from time to time to include new partners when they are admitted. The partnership interest of each existing partner is diluted on a pro rata basis when a new partner is admitted.

The business and affairs of LSV are managed under the direction of the Management Committee. The Management Committee consists of the remaining original partners and certain other partners of the Partnership. The voting interest by each partner on the Management Committee differs from their partnership ownership percentage.


2.	Summary of Significant Accounting Policies

Cash and Cash Equivalents

LSV considers investment instruments purchased with an original maturity of three months or less to be cash and cash equivalents.

Allowance for Doubtful Accounts

LSV provides an allowance for doubtful accounts equal to the estimated uncollectible amounts. LSV's estimate is based on historical collection experience and a review of the current status of Management fee receivables.

Revenue Recognition and Related Receivables

Management fee receivables on the accompanying Balance Sheets represent receivables earned and billed, as well as earned but unbilled. Unbilled receivables represent services provided but not yet billed. Management fee receivables on the accompanying Balance Sheets consist of the following:



	2018			2017
Management fee receivables	$	4,684		$	3,176
Unbilled management fee receivables	110,455			125,079
	115,139			128,255
Less: Allowance for doubtful accounts	(150		)	—
Total management fee receivables	$	114,989		$	128,255

The Partnership provides its services on a daily basis. LSV believes the performance obligation for providing its services is satisfied over time because the customer is receiving and consuming the benefits as they are provided by LSV. Fee arrangements are based on a percentage applied to the customer’s assets under management. Fees are received monthly or quarterly and are recognized as revenue at that time as they relate specifically to the services provided in that period, which are distinct from the services provided in other periods.

As additional consideration for its services noted above, LSV receives fees that vary based on specified performance measures, for example, when a fund or separate account exceeds a specified benchmark or contractual hurdle over a contractual performance period. These fees are earned once account returns have exceeded these specified performance measures and are calculated as a percentage of account

LSV Asset Management

Notes to Financial Statements

Years Ended December 31, 2018, 2017 and 2016

returns. These performance fees are considered variable consideration as the uncertainty is dependent on the value of the assets at future points in time as well as meeting a specified compound hurdle rate, both of which are highly susceptible to factors outside the Partnership’s influence. Revenues are recognized evenly over the contract period once it is probable that a significant reversal will not occur. LSV believes that ratable recognition over the service period is the appropriate approach for recognizing revenue because the services are substantially the same each day and have the same pattern of transfer. Performance fees recognized in the current period are primarily related to performance obligations that have been satisfied in prior periods.

On January 1, 2018, LSV adopted the Accounting Standards Update (ASU) No. 2014-9, Revenue from Contracts with Customers (Topic 606) (Accounting Standards Codification (ASC) 606 (ASC 606)). LSV adopted ASC 606 under the modified retrospective method. LSV reevaluated all of its revenue contracts and determined that the new guidance did not change the timing of when it recognizes revenue.

Allocations of Net Income or Net Loss

In accordance with the Partnership Agreement, all partnership net profits or losses are allocated among the partners in accordance with their respective ownership interests at the time the profits are realized. Such allocations are included in the “Partnership Capital” balance on the accompanying Statements of Changes in Partners' Capital.

Partnership Distributions

In accordance with the Partnership Agreement, Partners' distributions are based upon the net quarterly cash flows of the partnership. Such distributions represent reductions of partners' capital and are included in the Statements of Changes in Partners' Capital. Included in Partnership distributions are state taxes paid on certain partners' behalf and which represent a reduction in Partners' Capital.

Guarantees and Indemnifications

In the ordinary course of business, the Partnership from time to time enters into contracts containingindemnification obligations of the Partnership. These obligations may require the Partnership to make payments to another party upon the occurrence of certain events including the failure by the Partnership 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 Partnership. In many cases, there are no stated or notional amounts included in the indemnification provisions. There are no amounts reflected on the accompanying Balance Sheets related to these indemnifications.

Fixed Assets

Fixed assets consist of the following at December 31:



							Estimated Useful Lives
	2018			2017			Estimated Useful Lives
Equipment	$	3,585		$	2,946		3 to 5 years
Leasehold improvements	3,399			3,399			Lease Term
Furniture and fixtures	1,032			1,004			5 years
	8,016			7,349
Less: Accumulated depreciation and amortization	(6,851		)	(5,942		)
	$	1,165		$	1,407

LSV Asset Management

Fixed assets are recorded at historical cost. Depreciation of fixed assets is computed using the straight-line method over the estimated useful lives. Amortization of leasehold improvements is computed using the straight-line method over the shorter of the remaining lease term or the estimated useful lives of the improvements.

Management's Use of Estimates

The preparation of financial statements in conformity with generally accepted accounting principles in the United States requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statement and the reported amounts of revenue and expenses during the period. Actual results could differ from those estimates.

Concentration of Credit Risk

Financial instruments which potentially expose the Partnership to concentrations of credit risk consist primarily of Cash and cash equivalents and Management fee revenue and receivables. Cash and cash equivalents deposits can be maintained with institutions in excess of federally insured limits.

Concentrations of credit risk with respect to our receivables are limited due to the large number of clients and their dispersion across geographic areas. No single group or customer represents greater than 10 percent of total revenue or Management fee receivables.

Fair Value of Financial Instruments

The Partnership's financial instruments consist primarily of cash and cash equivalents. The book value of Cash and cash equivalents, Management fee receivables and Accrued liabilities is considered to be representative of their fair value because of their short maturities. The recorded value of these financial instruments approximates their fair value at December 31, 2018 and 2017.

The accounting standard for fair value measurements defines fair value as the exchange price that would be received for an asset or paid to transfer a liability (an exit price) in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants on the measurement date. The accounting standard also establishes a fair value hierarchy which requires an entity to maximize the use of observable inputs and minimize the use of unobservable inputs when measuring fair value.

New Accounting Pronouncements

In February 2016, the FASB issued ASU No. 2016-02, Leases (ASU 2016-02), as amended, requiring lessees to recognize a right-of-use asset and a lease liability on the balance sheet for all leases with the exception of short-term leases. For lessees, leases will be classified as either operating or finance leases, with the classification affecting the pattern and classification of expense recognition in the income statement. The updated standard is effective for LSV beginning in the first quarter of 2019. Early adoption is permitted. A modified retrospective transition approach is required, applying the new standard to all leases existing at the date of initial application. An entity may choose to use either (i) its effective date or (ii) the beginning of the earliest comparative period presented in the financial statements as its date of initial application. LSV expects to adopt the new standard on January 1, 2019 and use the effective date as the date of initial application. As a result, financial information will not be updated and the disclosures required under the new standard will not be provided for periods prior to January 1, 2019. The new standard provides a number of optional practical expedients in transition. LSV expects to elect the package of practical expedients which permits LSV to not reassess under the new standard its prior conclusions about lease identification, lease classification and initial direct costs. As part of its project plan’s preliminary assessment and design implementation phases for the adoption of ASU 2016-02, LSV has adopted implementation controls that allow it to properly and timely adopt ASU 2016-02 on the effective date. While LSV continues to assess all of the effects of adoption, LSV believes the most significant effects relate to the recognition of right-of-use assets and lease liabilities on the balance sheet for office space and certain office equipment and providing significant new disclosures about leasing arrangements. The Company has

completed the process of cataloging existing lease agreements and is currently calculating the right-of-use asset and lease liability.


3.	Commitments and Contingencies

The Partnership has entered into various operating leases for facilities. Some of these leases contain escalation clauses. The aggregate noncancellable minimum commitments at December 31, 2018 are as follows:



2019	$	1,249
2020	1,339
2021	1,361
2022	1,384
2023 and thereafter	6,145
	$	11,478

4.	Income Taxes

No federal or state income taxes are provided for by LSV as each partner is liable for income taxes on their respective share of LSV's taxable income, if any.

LSV's tax return is subject to examination by federal and state taxing authorities. If such examinations result in changes to LSV's taxable income, the tax liability of each partner would change accordingly.


5.	Related Party Transactions

Under LSV's Partnership Agreement, SEI Funds, Inc. is responsible for performing various services to support LSV's advisory business. In connection with such services, SEI Funds, Inc. allocates certain of its costs including employee benefits and other general and administrative expenses to LSV. The total allocated costs were $2,284, $2,130, and $1,824 in 2018, 2017, and 2016, respectively. The amount payable to SEI Funds, Inc. is included in the Due to SEI Funds, Inc. balance on the accompanying Balance Sheets. The balance Due to SEI Funds, Inc. is paid on a monthly basis, is non-interest bearing, and includes compensation, benefits and other general and administrative expenses.

LSV is a party to a number of portfolio investment advisory agreements with SEI Investments Management Corporation, SEI Investments Global, Limited, and SEI Investments Canada Company (all wholly-owned subsidiaries of SEI). Under these agreements, LSV receives an annual fee based on the assets under LSV's management in various SEI-sponsored funds. Total fees earned under these agreements were $20,091, $16,900 and $14,328 in 2018, 2017 and 2016, respectively. The Management fee receivables balance under these agreements on the accompanying Balance Sheets included $1,486 and $1,299 of such fees at December 31, 2018 and 2017, respectively.

Some LSV partners have investment interests in LSV funds. LSV receives an annual fee based on the assets under LSV’s management attributable to the Partners’ interest. Total fees earned from LSV partners for their investments in LSV funds were $3,048, $2,046, and $1,634 in 2018, 2017 and 2016, respectively.

Following completion of eligibility requirements, LSV employees are able to participate in the Capital Accumulation Plan (“CAP”), a SEI‑sponsored employee benefit plan. CAP is a tax-qualified defined contribution plan which provides retirement benefits, including provisions for early retirement and disability

LSV Asset Management

benefits, as well as a tax-deferred savings feature. Participants are vested in employer contributions at the time the contributions are made. All contributions are discretionary and are made from available profits. The employer contribution expense is included in Compensation, benefits and other personnel on the accompanying Statements of Operations. Costs incurred by the Partnership related to the CAP were immaterial in 2018, 2017, and 2016.

Following completion of eligibility requirements, LSV employees are able to participate in a SEI-sponsored employee stock purchase plan. The plan provides for offering of common stock to eligible employees at a price equal to 85 percent of the fair value at the end of the stock purchase period, as defined. Costs incurred by the Partnership related to the employee stock purchase plan were immaterial in 2018, 2017, and 2016.


6.	Accrued stock-based compensation

In March 2009, certain partners (the Contributing Partners) of LSV authorized for designation a portion of their partnership interest for the purpose of providing an interest in LSV to a select group of key employees. The partnership granted portions of the authorized partnership interest to key employees from March 2009 through April 2013. The issuance in April 2013 reflected the remaining amount of the designated partnership interest of the Contributing Partners. At the time partnership interest is granted, rights to receive distributions equal to the full granted percentage transfers to the recipient of the grant. Partnership equity equal to the amount of interest granted is earned over a predetermined vesting period. All profits, losses, distributions and other rights and obligations relating to authorized but undesignated partnership interest remained with the Contributing Partners until such interest was granted. Each issuance must be authorized by unanimous vote of all Contributing Partners. The issuance of an interest in LSV to a key employee provides them an interest in the future profits of LSV. It does not provide them any rights in the management of the partnership or the ability to direct the operations or affairs of LSV. The granted partnership interest is treated as a liability as it is settled in cash and is calculated on projected net income. The granted partnership interest redemption liability amounted to $28,271 and $27,082 at December 31, 2018 and 2017, respectively and is included in Accrued compensation on the accompanying Balance Sheets. The associated expense is recorded as Stock based compensation on the accompanying Statement of Operations.

7. Variable Interest Entities - Investment Products

LSV has created investment products for its clients in various types of legal entity structures that may be considered variable interest entities (VIEs). LSV serves as the Manager for these investment products and its clients are the equity investors. LSV does not have an equity investment in any of the VIEs and does not have an obligation to enter into any guarantee agreements with the VIEs. Some of the investment products are limited partnerships which have substantive kick-out rights. LSV is not the primary beneficiary as they lack any equity investment and their fees are paid outside of the fund. Therefore, LSV is not required to consolidate any investment products that are VIEs into its financial statements.

8. Subsequent Events

The Partnership performed an evaluation of subsequent events through February 25, 2019, which is the date the financial statements were made available to be issued.
