Business. General We provide an array of human resources (“HR”) and business solutions designed to help improve business performance. Since our formation in 1986, we have evolved from being solely a professional employer organization (“PEO”), an industry we pioneered, to our current position as a comprehensive business performance solutions provider. Our long-term strategy is to provide the best small and medium-sized businesses in the United States with our specialized human resources service offering and to leverage our buying power and expertise to provide additional valuable services to clients. Our most comprehensive HR services offerings are provided through our Workforce Optimization and Workforce Synchronization solutions (together, our “PEO HR Outsourcing solutions”), which encompass a broad range of human resources functions, including payroll and employment administration, employee benefits, workers’ compensation, government compliance, performance management, and training and development services, along with our cloud-based human capital management platform, Insperity Premier outsourcing solution and is our primary offering. Workforce Synchronization, which generally is offered only to our middle market client segment, is a lower cost offering with a typically longer commitment that includes the same compliance and administrative services as Workforce Optimization and allows those clients to select, for an additional fee, from the strategic HR products and services that are included with Workforce Optimization. . Workforce Optimization is our most comprehensive HR TM TM ® In addition to our PEO HR Outsourcing solutions, we offer Workforce Acceleration , a comprehensive service that includes traditional payroll and human capital management solutions. We also offer a number of other business performance solutions, including Comprehensive Traditional Payroll and Human Capital Management, Time and Attendance, Performance Management, Organizational Planning, Recruiting Services, Employment Screening, Retirement Services and Insurance Services, many of which are offered as a cloud- based software solution. These other products and services are offered separately or along with our PEO HR Outsourcing solutions or with Workforce Acceleration. TM Our PEO HR Outsourcing solutions are designed to improve the productivity and profitability of small and medium-sized businesses. These solutions relieve business owners and key executives of many employer-related administrative and regulatory burdens, which enable them to focus on the core competencies of their businesses. Our PEO HR Outsourcing solutions also promote employee performance through human resources management techniques designed to improve employee satisfaction. We enter into a Client Service Agreement (“CSA”) with each of our PEO HR Outsourcing solutions clients under which we and our client act as co-employers of the employees who work at the client’s worksite, or worksite employees (“WSEEs”). Under the CSA, we assume responsibility for personnel administration and assist our clients in complying with employment-related governmental regulations, while the client retains the employees’ services in its business and remains the employer for other purposes. We charge a comprehensive service fee (“comprehensive service fee” or “gross billing”), which is invoiced concurrently with the processing of payroll for the WSEEs of the client. The comprehensive service fee consists of the payroll of our WSEEs plus an additional amount reflected as a percentage of the payroll cost of the WSEEs. We accomplish the objectives of our PEO HR Outsourcing solutions through a “high-touch/high-tech” approach to service delivery. In advisory areas, such as recruiting, employee performance management and employee training, we employ a high-touch approach designed to ensure that our clients receive the personal attention and expertise needed to create a customized human resources solution. We utilize a variety of information technology capabilities to deliver our PEO HR Outsourcing solutions, including Insperity Premier , our cloud-based human capital management platform through which we, along with our clients and WSEEs, manage payroll, benefits, retirement solutions and other HR-related information, creating efficiencies for all parties. TM As of December 31, 2020, we had 70 offices, including 82 sales offices in 40 markets. In addition, we had four regional service centers along with human resources and client service personnel located in a majority of our 40 sales markets, which serviced an average of 239,232 WSEEs per month in the fourth quarter of 2020. Our service centers coordinate PEO HR Outsourcing solutions for clients on a regional basis and localized face-to-face human resources services. We were organized as a corporation in 1986. Our principal executive offices are located at 19001 Crescent Springs Drive, Kingwood, Texas 77339. Our telephone number at that address is (281) 358-8986, and our website address is www.insperity.com. Our stock is traded on the New York Stock Exchange under the symbol “NSP.” We file or furnish periodic reports with the Securities and Exchange Commission (“SEC”), including our annual reports on Form 10-K, Insperity 2020 Form 10-K 3 BUSINESS quarterly reports on Form 10-Q, current reports on Form 8-K, and if applicable, amendments to those reports filed or furnished pursuant to Section 13(a) or 15(d) of the Exchange Act. Through the investor relations section of our website, we make available electronic copies of the documents that we file or furnish to the SEC, the charters of the standing committees of our Board of Directors and other documents related to our corporate governance, including our Code of Conduct. Access to these electronic filings is available free of charge as soon as reasonably practicable after filing or furnishing them to the SEC. Printed copies of our committee charters and other governance documents and filings can be requested by writing to our corporate secretary at the address above. PEO Industry The PEO industry began to evolve in the early 1980s largely in response to the burdens placed on small and medium-sized employers by an increasingly complex legal and regulatory environment. While various service providers were available to assist these businesses with specific tasks, PEOs emerged as providers of a more comprehensive range of services relating to the employer/employee relationship. In a PEO arrangement, the PEO assumes certain aspects of the employer/employee relationship as defined in the contract between the PEO and its client. Because PEOs provide employer-related services to a large number of employees, they can achieve economies of scale that allow them to perform employment-related functions more efficiently, provide a greater variety of employee benefits, and devote more attention to human resources management than a client can individually. We believe the key factors driving demand for PEO services include: • • • the focus on growth and productivity of the small and medium-sized business community in the United States, utilizing outsourcing to concentrate on core competencies the need to provide competitive health care and related benefits to attract and retain employees the increasing costs associated with health and workers’ compensation insurance coverage, workplace safety programs, employee- related complaints and litigation • complex regulation of payroll, payroll tax and employment issues and the related costs of compliance, including the allocation of time and effort to such functions by owners and key executives • the significant costs, time and specialized knowledge required to purchase or develop the technology infrastructure to administer benefits, HR and payroll processing on an integrated basis A significant factor in the development of the PEO industry has been increasing recognition and acceptance of PEOs and the co-employer relationship by federal and state governmental authorities. Insperity and other industry leaders, in concert with the National Association of Professional Employer Organizations (“NAPEO”), have worked with the relevant governmental entities for the establishment of a regulatory framework that protects clients and employees, discourages unscrupulous and financially unsound PEOs, and promotes further development of the industry. Currently, 42 states have enacted legislation either recognizing PEOs or requiring licensing, registration, or certification, and several others are considering such regulation. Such laws vary from state to state but generally provide for monitoring the fiscal responsibility of PEOs. State regulation assists in screening insufficiently capitalized PEO operations and helps to resolve interpretive issues concerning employer/employee status for specific purposes under applicable state law. We have actively supported such regulatory efforts and are currently recognized, licensed, registered, certified or pursuing registration in all of these states. The cost of compliance with these regulations is not material to our financial position or results of operations. The Small Business Efficiency Act (“SBEA”) created a federal regulatory framework for the payment of wages to WSEEs and the reporting and remittance of federal payroll taxes on those wages paid by PEOs certified under the Internal Revenue Code as meeting certain requirements (“CPEOs”). We actively supported the enactment of this law. The SBEA clarified that a CPEO, rather than the client, is treated as the employer for purposes of reporting and remitting payroll taxes. It also clarified that a CPEO is treated as a successor employer for purposes of the wage base of WSEEs on which federal payroll taxes are applied. In addition, the law clarified that clients of a CPEO remain eligible for specified tax credits for which they would have been eligible absent the CPEO relationship. Following the establishment of the voluntary certification program by the Internal Revenue Service of the United States (“IRS”) and Treasury Department, our PEO subsidiary, Insperity PEO Services, L.P., received its designation as a CPEO from the IRS. Insperity 2020 Form 10-K 4 BUSINESS Service Offerings PEO HR Outsourcing Solutions We serve small and medium-sized businesses by providing our PEO HR Outsourcing solutions, which encompass a broad range of services. Both of our PEO HR Outsourcing solutions offer the following: • benefits and payroll administration • health and workers’ compensation insurance programs • personnel records management • employer liability management • assistance with government compliance • general HR advice • access to Insperity Premier for employees, managers and client owners • 401(k) retirement plan sponsored by us Our Workforce Optimization solution also provides additional services that our Workforce Synchronization clients can purchase for an additional fee, including the following: • employee recruiting and support • employee performance management • training and development services Our PEO HR Outsourcing solutions are designed to attract and retain high-quality employees, while relieving client owners and key executives of many employer-related administrative and regulatory burdens. Among the employment-related laws and regulations that may affect a client are the following: Internal Revenue Code (the “Code”) • • Federal Income Contribution Act (FICA) • Federal Unemployment Tax Act (FUTA) • Fair Labor Standards Act (FLSA) • Employee Retirement Income Security Act, as amended (ERISA) • Consolidated Omnibus Budget Reconciliation Act of 1985 (COBRA) • • Title VII (Civil Rights Act of 1964) Immigration Reform and Control Act (IRCA) • Health Insurance Portability and Accountability Act (HIPAA) • Age Discrimination in Employment Act (ADEA) • Americans with Disabilities Act (ADA) • The Family and Medical Leave Act (FMLA) • Genetic Information Nondiscrimination Act of 2008 • Drug-Free Workplace Act • Occupational Safety and Health Act (OSHA) • Worker Adjustment and Retraining Notification Act (WARN) • Uniformed Services Employment and Reemployment Rights Act (USERRA) • State unemployment and employment security laws • State workers’ compensation laws • Health Care and Education Reconciliation Act of 2010 (the “Reconciliation Act”) • Patient Protection and Affordable Care Act (PPACA) • State and local law equivalents of the foregoing • The Families First Coronavirus Response Act (FFCRA) • The Coronavirus Aid, Relief and Economic Security Act, also known as the CARES Act Insperity 2020 Form 10-K 5 BUSINESS These laws and regulations are complex, and in some instances overlapping. We assist our PEO HR Outsourcing solutions clients in complying with these laws and regulations by providing services in the categories set forth below: Administrative Functions. Administrative functions encompass a wide variety of processing and recordkeeping tasks, mostly related to payroll administration and regulatory compliance. Specific examples include: • payroll processing • payroll tax deposits • payroll tax reporting • employee file maintenance • unemployment claims processing • workers’ compensation claims reporting and monitoring Benefit Plans Administration. We maintain several benefit plans for eligible WSEEs including the following: • a group health plan • a health savings account program • a health care flexible spending account plan • a 401(k) retirement plan • cafeteria plans for group health and health savings account contributions • short-term and long-term disability insurance • an educational assistance program • an adoption assistance program • group term life insurance • group universal life insurance • accidental death and dismemberment insurance • paid family leave, where required by law The group health plan includes medical, dental, vision and prescription drug coverage, as well as a work-life program. All benefit plans are provided to eligible employees based on the specific eligibility provisions of each plan. We are the policyholder responsible for the costs and premiums associated with any group insurance policies that provide benefits under these plans, and we act as plan sponsor and administrator of the plans. We negotiate the terms and costs of the plans, maintain the plans in accordance with applicable federal and state regulations and serve as liaison for the delivery of these benefits to WSEEs and corporate employees. COBRA coverage is extended to eligible terminated WSEEs and other eligible individuals in accordance with applicable law. We believe that the variety and comprehensive nature of our benefit plan offerings are generally not available to employees in our small and medium-sized business target market and are usually offered only by larger companies that can spread program costs over a much larger group of employees. As a result, we believe the availability of these benefit plans provides our clients with a competitive advantage that small and medium-sized businesses are typically unable to attain on their own. Insperity Premier. Insperity Premier is our cloud-based human capital management platform for our PEO HR Outsourcing solutions and is available to our clients with minimal implementation effort or cost. It is designed to provide our service providers with insight into client and WSEE HR information to better support their needs.

Under the CSA, we assume many of the employment-related responsibilities associated with the administrative functions, benefit plans administration and personnel management services we provide. For many of those employment- related responsibilities that are the responsibility of the client or of both the client and us, we may assist our clients in managing and limiting liability. This assistance may include safety-related risk management reviews as well as the implementation by our clients of safety programs designed to reduce workplace accidents and, consequently, workers’ compensation claims. We also provide guidance to clients for avoiding discrimination, sexual harassment and civil rights violations, and we assist with termination decisions when consulted to attempt to minimize liability on those grounds. While we do not provide legal services to our clients, we employ in-house and external counsel who specialize in several areas of employment law, have broad experience in disputes concerning the employer/employee relationship and provide support to our internal human resources professionals. As part of our comprehensive service, we also maintain employment practice liability insurance coverage for ourselves and our clients, monitor developments in HR-related laws and regulations, and notify clients of the potential effect of such changes on employer liability. SM MarketPlace provided by Insperity . Through our many alliances with best-of-class providers, Insperity’s MarketPlace is an e-commerce portal that brings a wide range of products and services to our clients, WSEEs and their families. Through MarketPlace, which is provided through Insperity Premier, our clients also have the opportunity to offer their products and services to other clients and WSEEs. ® Middle Market Solutions. We believe the middle market sector, which we generally define as those companies with employees ranging from approximately 150 to 5,000 WSEEs, has historically been under-served by the PEO industry. Currently, we have a dedicated sales management, service personnel and consulting staff who concentrate solely on the middle market sector. Our average number of WSEEs per month in our middle market sector decreased 5.6% from 2019, representing approximately 24.4% and 25.7% of our total average paid WSEEs during 2020 and 2019, respectively. Clients with an average number of WSEEs exceeding 1,000 paid WSEEs represented 4.7% and 5.0% of our total average paid WSEEs during 2020 and 2019, respectively. Other Product and Services Offerings We offer other product and services offerings on a stand-alone basis and to our PEO HR Outsourcing solutions clients. We also strive to leverage our relationships with our customers to enable cross-selling of our various products and services.

Insurance Services also assists individuals in obtaining insurance coverages. Client Service Agreement All PEO HR Outsourcing solutions clients execute a CSA with us. The CSA provides for an ongoing relationship between Insperity and the PEO HR Outsourcing solutions client. For most clients, the CSA generally is an annual contract subject to earlier termination by Insperity or the client upon 30 days’ written notice or upon shorter notice in the event of default. CSAs for our middle market clients are generally two- year contracts, subject to earlier termination by clients upon payment of a termination fee or otherwise by the parties upon an event of default. The CSA establishes our comprehensive service fee, which is subject to periodic adjustments to account for changes in the composition of the client’s workforce, employee benefit election changes, and statutory changes that affect our costs. Under the CSA, clients active in January of any year are obligated to pay the estimated payroll tax component of the comprehensive service fee in a manner that reflects the pattern of incurred payroll tax costs. This practice aligns clients’ payments to us with our obligations to make payments to tax authorities, which are higher in the earlier part of the year and decrease as limits on wages subject to payroll tax are reached. The CSA also establishes the division of responsibilities between us and the client as co-employers. Pursuant to the CSA, we are responsible for personnel administration and for compliance with certain employment-related government regulations. In addition, we assume liability for payment of salaries and wages (as well as related payroll taxes) of our WSEEs and responsibility for providing specified employee benefits to such persons. These liabilities are not contingent on the prepayment by the client of the associated comprehensive service fee. Instead, as a result of our employment relationship with each of our WSEEs, we are liable for payment of salary and wages to the WSEEs as reported by the client and are responsible for providing specified employee benefits to such persons regardless of whether the client Insperity 2020 Form 10-K 9 BUSINESS pays the associated comprehensive service fee. The client retains the employees’ services and remains liable for complying with certain government regulations that require control of the worksite or daily supervisory responsibility or is otherwise beyond our ability to assume. A third group of responsibilities and liabilities are assumed by both Insperity and the client where such concurrent responsibility is appropriate. The specific division of applicable responsibilities under our CSAs generally is as follows: Insperity Responsibilities • Payment of wages and salaries as reported by the client and related tax reporting and remittance (local, state and federal withholding, FICA, FUTA, state unemployment) • Workers’ compensation compliance, procurement, management and reporting • Compliance with the Code, COBRA, HIPAA and ERISA for Insperity-sponsored employee benefit plans, as well as monitoring changes in other governmental laws and regulations governing the employer/employee relationship and updating the client when necessary • Offering benefits under Insperity-sponsored employee benefit plans that comply with PPACA requirements • Employee benefits administration of plans sponsored solely by Insperity Client Responsibilities • Payment, through Insperity, of commissions, bonuses, vacations, paid time off, sick pay, paid leaves of absence, and severance payments • Payment and related tax reporting and remittance of non-qualified deferred compensation and equity-based compensation • Products produced and/or services provided • Compliance with OSHA regulations, EPA regulations, FLSA, FMLA, WARN, USERRA, and state and local equivalents and compliance with government contracting provisions • Compliance with federal, state, and local pay or play health care mandates and all such other similar federal, state and local legislation • Compliance with the National Labor Relations Act (“NLRA”), including all organizing efforts and expenses related to a collective bargaining agreement and related benefits • Professional licensing requirements, fidelity bonding, and professional liability insurance • Ownership and protection of all client intellectual property rights • COBRA, HIPAA, PPACA, the Code and ERISA compliance for client-sponsored employee benefit plans • For clients electing payroll tax deferrals and tax credits under the FFCRA and CARES Act, the client has sole responsibility for determining eligibility under the programs and for reporting and depositing deferred amounts with the U.S. Treasury Concurrent Responsibilities • • Implementation of policies and practices relating to the employee/employer relationship Internal compliance with all federal, state and local employment laws, including Title VII of the Civil Rights Act of 1964, ADEA, Title I of ADA, the Consumer Credit Protection Act and immigration laws and regulations We maintain employment practice liability insurance coverages (including coverages for our clients) to manage our exposure for various employee-related claims. Our incurred costs in excess of annual premiums with respect to this exposure have historically been insignificant to our operating results. Insperity 2020 Form 10-K 10 BUSINESS Because we are a co-employer with the client for some purposes, it is possible that we could incur liability for violations of such laws, even if we are not responsible for the conduct giving rise to such liability. Our CSA ordinarily addresses this issue by providing that the client will indemnify us for liability incurred to the extent the liability is attributable to conduct by the client. Notwithstanding this contractual right to indemnification, it is possible that we could be unable to collect on a claim for indemnification and may therefore be ultimately responsible for satisfying the liability in question. In most instances, clients are required to remit their comprehensive service fees no later than the same day as the applicable payroll date by wire transfer or automated clearinghouse transaction. Although we are ultimately liable, as the employer for payroll purposes, to pay employees for work previously performed, we retain the ability to terminate immediately the CSA and associated WSEEs or to require prepayment, letters of credit, or other collateral upon deterioration in a client’s financial condition or upon non-payment by a client. These rights, the periodic nature of payroll, and the overall quality of our client base have resulted in an excellent overall collections history. PEO HR Outsourcing Solutions Clients Insperity’s PEO HR Outsourcing solutions provide value-added, full-service human resources solutions we believe are most suitable to a specific segment of the small and medium-sized business community. We target successful businesses with approximately 10 to 5,000 employees that recognize the advantage in the strategic use of high-performance human resources practices. We have set a long-term goal to serve approximately 10% of the overall small and medium-sized business community in terms of WSEEs. We serve clients and WSEEs located throughout the United States. By region, our revenue distribution for the year ended December 31, 2020, was as follows: Please read Note 1 “Accounting Policies,” to the Consolidated Financial Statements for additional information related to the change in revenues by region. All prospective PEO HR Outsourcing solutions clients are evaluated on the basis of a comprehensive analysis of employer-related risks entailing many factors, including (where permitted) industry and operations, workplace safety and workers’ compensation, unemployment history, operating stability, group medical information, human resources practices and other employer risks. As part of our client selection strategy, we strive to minimize offering our PEO HR Outsourcing solutions to businesses falling within certain specified NAICS (North American Industry Classification System) codes for those industries that we believe present a higher employer risk such as employee injury, high turnover or litigation. Insperity 2020 Form 10-K 11 BUSINESS Our PEO HR Outsourcing solutions client base is broadly distributed throughout a wide variety of industries as follows: This diverse client base lowers our exposure to downturns or volatility in any particular industry. However, our performance could be affected by a downturn in one of these industries or by general economic conditions within the small and medium-sized business community. We focus heavily on client retention. During 2020 and 2019, our retention rate was approximately 82% and 85%, respectively. For all PEO HR Outsourcing solutions clients, the average annual retention rate over the last five years was approximately 85%. Client attrition is attributable to a variety of factors, including: (1) client non-renewal due to price or service factors; (2) client business failure, sale, merger or disposition; (3) our termination of the CSA resulting from the client’s non-compliance or inability to make timely payments; and (4) competition from other PEOs or business services firms. Insperity 2020 Form 10-K 12 BUSINESS Marketing and Sales As of December 31, 2020, we had 82 sales offices located in 40 markets. Our sales offices typically consist of six to eight Business Performance Advisors (“BPAs”), a district sales manager, and an office administrator. To take advantage of economic efficiencies, multiple sales offices may share a physical location. Insperity’s markets and their respective year of entry are as follows: Market Sales Offices Initial Entry Date Market Sales Offices Initial Entry Date Houston San Antonio Austin Orlando Dallas/Fort Worth Atlanta Phoenix Chicago Washington D.C.

We continue to evaluate a broad range of factors in the selection process, using a market selection model that weighs various criteria that, based on our experience, we believe are reliable predictors of successful penetration. Among the factors we consider are: • market size, in terms of small and medium-sized businesses engaged in selected industries that meet our risk profile • market receptivity to PEO services, including the regulatory environment and relevant history with other PEO providers • existing relationships within a given market, such as vendor or client relationships • expansion cost issues, such as advertising and overhead costs • direct cost issues that bear on our effectiveness in controlling and managing the cost of our services, such as workers’ compensation and health insurance costs, unemployment risks, and various legal and other factors • a comparison of the services we offer to alternatives available to small and medium-sized businesses in the relevant market, such as the cost to the target clients of procuring services directly or through other PEOs • long-term strategy issues, such as the general perception of markets and our estimate of the long-term revenue growth potential of the market Insperity 2020 Form 10-K 13 BUSINESS We develop a mix of national and local advertising media and a placement strategy tailored to each individual market. After selecting a market and developing our marketing mix, but prior to entering the market, we engage in an organized media and public relations campaign to prepare the market for our entry and to begin the process of generating sales leads. We market our services through various business promotions and a broad range of media outlets, including digital marketing, television, radio, newspapers, periodicals and direct mail. We employ public relations firms for most of our markets as well as advertising consultants to coordinate and implement our marketing campaigns. We have developed an inventory of television, radio and newsprint advertisements, which are utilized in this effort. We routinely seek to develop new marketing approaches and campaigns to capitalize on changes in the competitive landscape for our human resources services and to more successfully reach our target market. We have an agreement with the Professional Golf Association Champions Tour to be the title sponsor of the annual Insperity Invitational held annually in The Woodlands, Texas (a suburb of Houston). In addition, we have an arrangement with Jim Nantz, a sports commentator, to serve as our national spokesperson. Our marketing campaigns use this event and the relationship with Mr. Nantz as a focal point of our brand marketing efforts. presented by UnitedHealthcare professional golf tournament ™ ® Our organic growth model generates sales leads from five primary sources: direct sales efforts, advertising, third-party channel programs, referrals, marketing alliances, and the Internet. These leads result in initial presentations to prospective PEO HR Outsourcing solutions clients, and ultimately, prospective PEO HR Outsourcing solutions client business profiles. A prospective PEO HR Outsourcing solutions client’s business profile reflects information gathered by the BPA about the prospect’s employees, including base compensation, level of benefits coverage options, job classification, state of employment and workers’ compensation classification. This information is used to generate a bid from our customized bid system, which applies Insperity’s proprietary pricing model to the census data. Concurrent with this process, we evaluate prospective clients through the previously described comprehensive employer risk analysis. Upon completion of a favorable employer risk evaluation, the BPA presents the bid and attempts to complete the sale and enroll the prospect. Our selling process typically takes approximately 90 days for clients with less than 150 employees, and 180 days or longer for middle market clients. The process can be extended during economic downturns. We have implemented cross-selling channels between our PEO HR Outsourcing solutions business and our other products and services. This cross-selling strategy focuses on using our PEO HR Outsourcing solutions to increase market penetration in each of our other products and services and using our other product and service offerings as a source of leads for our PEO HR Outsourcing solutions. The cross-selling channels attempt to reduce barriers to selling our products and services and allow us to tailor service packages to better meet the specific needs of the business. Competition We provide a value-added, full-service human resources solution through our PEO HR Outsourcing solutions, which we believe is most suitable to a specific segment of the small and medium-sized business community. This full-service approach is exemplified by our commitment to provide a high level of service and technology personnel, which has produced a ratio of corporate staff to WSEEs (the “staff support ratio”) that is higher than average for the PEO industry. Based on an analysis of the 2017 through 2019 annual NAPEO surveys of the PEO industry, we have successfully leveraged our full-service approach into significantly higher returns for Insperity on a per WSEE per month basis. During the three-year period from 2017 through 2019, our staff support ratio averaged 51% higher than the PEO industry average. During the same three-year period, our gross profit per WSEE and operating income per WSEE exceeded industry averages by 137% and 225%, respectively. Competition in the PEO industry revolves primarily around quality of services, scope of services, choice and quality of benefits packages, reputation, and price. We believe reputation, national presence, regulatory expertise, financial resources, risk management, and information technology capabilities distinguish leading PEOs from the rest of the industry. We also believe we compete favorably in these areas; however, other PEOs may offer their PEO services at lower prices than we offer. Due to the differing geographic regions and market segments in which most PEOs operate, and the relatively low level of market penetration by the industry, we consider our primary competition for our PEO HR Outsourcing solutions to be the traditional in-house provision of human resources services. The PEO industry is highly fragmented and we have seen competition intensify; however, we believe Insperity is one of the largest PEO service providers in the United States. Our largest national competitors include the PEO divisions of large business services companies such as Automatic Data Processing, Inc. and Paychex, Inc., and other national PEOs, such as TriNet Group, Inc. In addition, we also face Insperity 2020 Form 10-K 14 BUSINESS competition from: (1) fee-for-service providers such as payroll processors and human resources consultants; (2) human resources technology solution companies; and (3) large regional PEOs in certain areas of the country. As Insperity and other large PEOs expand nationally, we expect that competition may intensify. Vendor Relationships Insperity provides benefits to its WSEEs under arrangements with a variety of vendors. We consider our contracts with UnitedHealthcare (“United”) and the Chubb Group of Insurance Companies (“Chubb”) to be the most significant elements of our employee benefits package, as they would be the most difficult to replace. We provide group health insurance coverage to our WSEEs through a national network of carriers including United, UnitedHealthcare of California, Kaiser Permanente, Blue Shield of California, HMSA BlueCross BlueShield of Hawaii and Tufts, all of which provide fully insured policies or service contracts. The health insurance contract with United provides approximately 87% of our health insurance coverage and expires on December 31, 2022, subject to cancellation by either party upon 180 days’ notice. For a discussion of our contract with United, which is accounted for using a partially self-funded insurance accounting model, please read Item 7. “Management’s Discussion and Analysis of Financial Condition and Results of Operations—Critical Accounting Policies and Estimates—Benefits Costs.” Our workers’ compensation coverage (the “Chubb Program”) has been provided through an arrangement with Chubb (formerly ACE American Insurance Company) since 2007. The Chubb Program is a fully insured program whereby Chubb has the responsibility to pay all claims incurred under the policies regardless of whether we satisfy our responsibilities. The current workers’ compensation coverage with Chubb expires on September 30, 2021. Chubb has committed to extend coverage for two additional policy years (through September 30, 2023) subject to certain terms and conditions related to the division of responsibilities in the program. In the event we are unable to secure replacement coverage on competitive terms, significant disruption to our business could occur. For additional discussion of the Chubb Program, which includes terms shifting some of the financial responsibility for claims to us, please read Item 7. “Management’s Discussion and Analysis of Financial Condition and Results of Operations—Critical Accounting Policies and Estimates—Workers’ Compensation Costs.” Information Technology Insperity utilizes a variety of information technology capabilities to provide its PEO HR Outsourcing solutions and business performance improvement services to its clients and WSEEs and for its own administrative and management information requirements. Insperity’s PEO HR Outsourcing solutions information systems, which include Insperity Premier, are a proprietary mix of applications that includes both internally developed software, licensed software applications and cloud-based services. These systems manage a wide range of transactions and information specific to our PEO HR Outsourcing solutions, to Insperity and to our clients and WSEEs, including: • WSEE enrollment • human resources management and employee administration • benefits and defined contribution plan administration • time and attendance collection and administration • payroll processing • client invoicing and collection • management information and reporting • sales bid calculations Central to these systems are transaction processing capabilities that allow us to process a high volume of employee enrollment, employee administration, payroll, invoice and bid transactions that meet the specific needs of our clients and prospects. We administer our employee benefits through a proprietary application designed to process employee eligibility and enrollments, manage carrier relationships and maintain a variety of plan offerings. Our retirement services Insperity 2020 Form 10-K 15 BUSINESS operations are conducted utilizing an industry-leading retirement plan administration application in a third-party hosted environment. Aspects of all of these components are delivered to our PEO HR Outsourcing solutions clients and WSEEs through Insperity Premier. We utilize commercially available software and cloud-based solutions for other business functions such as finance and accounting, sales force activity management and customer relationship management. Insperity has hosting facilities located at two separate leased facilities, located in Bryan, Texas and The Woodlands, Texas. These facilities host the majority of our business applications, information security infrastructure and network equipment. Each hosting facility houses a mix of primary production applications, disaster recovery, replication and back-up applications, and pre-production environments, with the Bryan facility acting as our primary data center for all mission-critical applications. Both hosting facilities have the capacity to run all of our critical business applications and have sufficient capacity to handle all of our operations on a stand-alone basis, if required. We have an active Business Continuity Plan, which includes information technology capabilities and we utilize a variety of measures to ensure our Business Continuity Plan remains effective and available. Our network infrastructure is designed to ensure appropriate connectivity exists among all of our facilities and employees and provides appropriate Internet connectivity to conduct business with our clients and WSEEs. The network infrastructure is provided through industry standard core network hardware and via high-speed network services provided by multiple vendors. We have incorporated a variety of measures designed to maintain the security and privacy of the information managed through our systems and applications. These measures include industry standard technologies designed to protect, monitor and assess our data centers and network environment; best practice security policies and procedures; and a variety of measures designed to control access to sensitive and private information. Industry Regulations The operations for our PEO HR Outsourcing solutions are affected by numerous federal and state laws relating to tax, insurance and employment matters. By entering into a co-employer relationship with our WSEEs, we assume certain obligations and responsibilities of an employer under these federal and state laws. Because many of these federal and state laws were enacted prior to the development of nontraditional employment relationships, such as PEOs, temporary employment and outsourcing arrangements, many of these laws do not specifically address the obligations and responsibilities of nontraditional employers. Currently, the federal government and 42 states have passed laws that either recognize PEOs, require licensing or registration of PEOs, or provide voluntary certification programs for PEOs, and several others are considering such regulation. The SBEA established a voluntary certification program and created a federal regulatory framework for the payment of wages to WSEEs and for the reporting and remittance of federal payroll taxes on those wages paid by CPEOs. Our PEO subsidiary, Insperity PEO Services, L.P., is a CPEO. Please read Item 1. “Business—PEO Industry” for further information. As an employer, we are subject to federal statutes and regulations governing the employer/employee relationship. Subject to the issues discussed below, we believe that our operations are in compliance, in all material respects, with all applicable federal statutes and regulations. Employee Benefit Plans We offer various employee benefits plans to eligible employees, including our WSEEs. These plans include: • a group health plan, which includes medical, dental, vision and prescription drug coverage, as well as a work-life program • a 401(k) retirement plan • cafeteria plans under Code Section 125 • a health savings account program • a welfare benefits plan, which includes life, disability, and accidental death and dismemberment coverage • a health care flexible spending account plan Insperity 2020 Form 10-K 16 BUSINESS • an educational assistance program • an adoption assistance program • a commuter benefits program Generally, employee benefit plans are subject to provisions of the Code, ERISA, and COBRA. The number and complex nature of federal and state regulations relating to employer-sponsored health plans has continued to increase over time. We believe that additional regulatory burdens placed on employers can increase the demand for our services because small and medium-sized businesses are especially challenged in their efforts to comply with governmental regulations due to limited resources and a lack of expertise. As a co-employer in the PEO relationship, we assume or share many of the employer-related responsibilities and assist our clients in complying with many employment-related governmental laws and regulations. Historically, we believe that we have successfully marketed the compliance component of our service offering and that our compliance-related services have increased the value proposition of our service offering. Employer Status. In order to qualify for favorable tax treatment under the Code, employee benefit plans must be established and maintained by an employer for the exclusive benefit of its employees. Generally, an entity is an “employer” of individuals for federal employment tax purposes if an employment relationship exists between the entity and the individuals under the common law test of employment. In addition, the officers of a corporation are deemed to be employees of that corporation for federal employment tax purposes. The common law test of employment, as applied by the IRS, involves an examination of approximately 20 factors to ascertain whether an employment relationship exists between a worker and a purported employer. Generally, the test is applied to determine whether an individual is an independent contractor or an employee for federal employment tax purposes and not to determine whether each of two or more companies is a “co- employer.” Substantial weight is typically given to the question of whether the purported employer has the right to direct and control the details of an individual’s work. Among the factors that appear to have been considered more important by the IRS are: • • • the employer’s degree of behavioral control (the extent of instructions, training and the nature of the work) the financial control or the economic aspects of the relationship the intended relationship of the parties (whether employee benefits are provided, whether any contracts exist, whether services are ongoing or for a project, whether there are any penalties for discharge/termination, and the frequency of the business activity) ERISA Requirements. Employee pension and welfare benefit plans are also governed by ERISA. ERISA defines “employer” as “any person acting directly as an employer, or indirectly in the interest of an employer, in relation to an employee benefit plan.” ERISA defines the term “employee” as “any individual employed by an employer.” The United States Supreme Court has held that the common law test of employment must be applied to determine whether an individual is an employee or an independent contractor under ERISA. A definitive judicial interpretation of “employer” in the context of a PEO or employee leasing arrangement has not been established. If Insperity were found not to be an employer with respect to WSEEs for ERISA purposes, its plans would not comply with ERISA and/or the Code. Further, as a result of such finding, Insperity and its plans would not enjoy, with respect to WSEEs, the preemption of state laws provided by ERISA and could be subject to varying state laws and regulations as well as to claims based upon state common laws. Even if such a finding were made, we believe we would not be materially adversely affected because we would endeavor to make available similar benefits at comparable costs. In addition to ERISA and the Code, issues related to the relationship between Insperity and its WSEEs may also arise under other federal laws, including other federal income tax laws. Patient Protection and Affordable Care Act. The PPACA was signed into law on March 23, 2010. The PPACA was subsequently amended on March 30, 2010, by the Reconciliation Act. The PPACA and the Reconciliation Act (collectively the “Act”) entail sweeping health care reforms with original staggered effective dates from 2010 through 2018, some of which were subsequently extended until as late as 2020. While the Act did not have a material adverse impact on our results of operations in 2020, the future impact of the following provisions or changes to the provisions, including any changes or a repeal that may result from a case pending before the U.S. Supreme Court or future legislative actions, is unknown at this time. Insperity 2020 Form 10-K 17 BUSINESS Beginning in 2014, the Act provided for the establishment of state insurance exchanges (“Exchanges”) to make health insurance available to individuals and small employers (initially defined as 100 employees or less). States had the option of building a state-based exchange, entering into a state-federal partnership exchange or accepting the federally-facilitated exchange. States that accept the federally-facilitated exchange can transition to a state-based exchange at a later date. The Exchanges provide consumers with educational services and information on available options and offer a variety of health plans. Subsidies are available to qualifying individuals who purchase health insurance through the Exchanges. As part of the Tax Cuts and Jobs Act enacted in December 2017, the requirements that individuals maintain health insurance coverage or pay a federal tax penalty, which was known as the individual mandate, was effectively eliminated beginning in 2019. A limited number of states have enacted individual mandates. At this time, the Exchanges, tax credits, individual mandates and subsidies have not had a material impact on our operations, but the impact of future changes to these provisions is unknown. Additionally, in 2014, the Act ushered in a number of insurance market reforms for the small group and individual markets. The reforms required guaranteed issue and renewability of coverage, eliminated certain underwriting practices by issuers, consolidated the number of risk pools in each state and restricted the permissible factors and variable ranges of those factors that can be considered in determining health insurance premiums. Transition relief permitted states to delay the effective date of some of these reforms. At this time, the insurance market reforms have not had a material adverse impact on our business operations, but the impact of future changes on our ability to attract and retain clients, or our ability to increase service fees to offset any increased costs is unknown. Effective January 1, 2015, “pay or play” requirements applied to large employers with at least 50 full-time and full-time equivalent employees in the prior calendar year (“Applicable Large Employers” or “ALEs”). ALEs who fail to offer “minimum essential coverage” satisfying minimum value and affordability requirements may be subject to a penalty if a full-time employee obtains coverage from an Exchange and receives a subsidy or tax credit for such coverage. While clients are responsible for employer pay or play health care mandates under the CSA, the Insperity-sponsored group health plan qualifies as minimum essential coverage and is designed to satisfy the minimum value and affordability requirements. Clients are not required to use the affordability safe harbor utilized by us. Information contained in the Congressional Record, which specifically references PEOs, indicates that any pay or play penalties should apply separately to clients of a PEO and not at the PEO level. However, the Act and subsequently issued IRS guidance do not expressly address the issue of whether the pay or play penalties apply only at the client level or whether the penalties can be applied at the PEO level. At this time, we are unable to determine if pay or play penalties may be assessed against a PEO for coverage provided to WSEEs under a PEO sponsored plan. As part of the Tax Extenders Act passed in 2019, the rules imposing excise taxes commencing in 2022 on employers and insurers who offer excessive health benefits under so-called “Cadillac plans” have been repealed. At this time, we are unable to determine the effect that the repeal of these pending excise taxes will have on our business. 401(k) Retirement Plans. Our 401(k) Retirement Plan for WSEEs are operated pursuant to guidance provided by the IRS under Revenue Procedure 2002-21 and Revenue Procedure 2003-86, each of which provides guidance for the operation of defined contribution plans maintained by PEOs that benefit WSEEs. This guidance provides qualification standards for PEO plans that, if met, negate the inquiry of common law employer status for purposes of the exclusive benefit rule. All of Insperity’s 401(k) Retirement Plans have received determination letters from the IRS confirming the qualified status of the plans. Employment Taxes As a co-employer, Insperity generally assumes responsibility and liability for the payment of federal and state employment taxes with respect to wages and salaries paid to our WSEEs. There are essentially three types of federal employment tax obligations included in Subtitle C - Employment Taxes of the Code: • withholding of income tax requirements governed by Code Section 3401, et seq. • obligations under FICA, governed by Code Section 3101, et seq. • obligations under FUTA, governed by Code Section 3301, et seq. Insperity 2020 Form 10-K 18 BUSINESS Under these Code sections, employers have the obligation to withhold and remit the employer portion and, where applicable, the employee portion of these taxes. The SBEA provides that a CPEO shall be treated as the employer under Subtitle C – Employment Taxes of the Code and shall be responsible for reporting federal employment taxes rather than the CPEO clients. For any client CSA that is not a CPEO contract, Code Section 3401, which applies to federal income tax withholding requirements, contains an exception to the general common law test applied to determine whether an entity is an “employer” for purposes of federal income tax withholding. Code Section 3401(d)(1) states that if the person for whom services are rendered does not have control of the payment of wages, the “employer” for this purpose is the person having control of the payment of wages. The Treasury regulations issued under Code Section 3401(d)(1) state that a third party can be deemed to be the employer of workers under this section for income tax withholding purposes where the person for whom services are rendered does not have legal control of the payment of wages. While several courts have examined Code Section 3401(d)(1), its ultimate scope has not been delineated. Moreover, the IRS has to date relied extensively on the common law test of employment in determining liability for failure to comply with federal income tax withholding requirements. Accordingly, while we believe that we can assume the withholding obligations for WSEEs, in the event we fail to meet these obligations, the client may be held ultimately liable for those obligations. While this interpretive issue has not to our knowledge discouraged clients from enrolling with Insperity, there can be no assurance that a definitive adverse resolution of this issue would not do so in the future. These interpretive uncertainties may also impact our ability to report employment taxes on our own account rather than the accounts of our clients. Clients who elected social security deferrals under the recent CARES Act have sole responsibility for reporting and depositing deferred amounts with the U.S. Treasury. Unemployment Taxes We record our state unemployment insurance (“SUI”) tax expense based on taxable wages and tax rates assigned by each state. State unemployment tax rates vary by state and are determined, in part, based on Insperity’s prior years’ compensation experience in each state. Certain rates are determined, in part, by each client’s own compensation experience. In addition, states have the ability under law to increase unemployment tax rates, including retroactively, to cover deficiencies in the unemployment tax funds. Rate notices are typically provided by the states during, or prior to, the first quarter of each year; however, some notices are received later. Until we receive the final tax rate notices, we estimate our expected SUI rate in those particular states. State Regulation While some states do not explicitly regulate PEOs, 42 states have adopted provisions for licensing, registration, certification or recognition of PEOs, and several others are considering such regulation. Such laws vary from state to state but generally provide for monitoring the fiscal responsibility of PEOs, and in some cases codify and clarify the co-employment relationship for unemployment, workers’ compensation and other purposes under state law. We believe that we are in compliance with the material requirements in all 42 states that have such laws. Regardless of whether a state has licensing, registration or certification requirements for PEOs, we must comply with a number of other state and local regulations that could impact our operations. Human Capital We had approximately 3,600 corporate employees as of December 31, 2020. We believe our relations with our corporate employees are good. None of our corporate employees are covered by a collective bargaining agreement. The number of BPAs and trained BPAs impacts our ability to grow our customer base. We refer to BPAs who have been employed for two months and completed initial sales training as “trained BPAs”. During 2020 and 2019, the average number of BPAs were 645 and 590, respectively, while the average number of trained BPAs were 590 and 528, respectively. Intellectual Property Insperity currently has registered trademarks, copyrights and other intellectual property. We believe that our trademarks as a whole are of considerable importance to our business. Insperity 2020 Form 10-K 19 RISK FACTORS Item 1A. Risk Factors. The statements in this section describe the known material risks to our business and should be considered carefully. Economic Risks Adverse economic conditions could negatively affect our industry, business, and results of operations. The small and medium-sized business market is sensitive to changes in economic activity levels as well as the credit markets. As a result, the demand for the outsourced HR services we provide clients could be adversely impacted by weak economic conditions or difficulty obtaining credit. Current and prospective clients may respond to such conditions by reducing employment levels, compensation levels, employee benefit levels and outsourced HR services. In addition, during periods of weak economic conditions, current clients may have difficulty meeting their financial obligations to us and may select alternative HR services at more competitive rates than we offer. Further, our growth is partially dependent on hiring of new employees by our existing clients, which may be restricted during periods of tight labor markets and economic slowdown, such as the current period of high unemployment levels, and resulting reduced hiring within our existing client base. Such developments could adversely impact our financial condition, results of operations and future growth rates. The economic impact of the COVID-19 pandemic is adversely affecting our business. The current pandemic may have, and a future outbreak of other highly infectious or contagious diseases could have, a material and adverse impact on our business, results of operations, financial condition and cash flows. The spread of the COVID-19 virus has created significant volatility, uncertainty and economic disruption, including actions taken by businesses and governments in response to the pandemic that have resulted or could result in a significant reduction in commercial activity. The extent to which the COVID-19 pandemic impacts our business, operations, financial results and financial condition will depend on numerous evolving factors that are highly uncertain and that we may not be able to accurately predict, including: • • • • • • scope, severity and duration of the pandemic; varying impact that the pandemic has within each locality; actions taken by government authorities to contain the outbreak or address its impact; development, distribution, adoption and cost of safe and effective treatments or vaccines for COVID-19; direct and indirect economic effects of the pandemic and containment measures; scope, significance and duration of business disruptions on small and medium-sized businesses, including any reduction in employment levels, compensation levels and employee benefits; • magnitude and extent of business failures among the small and medium-sized businesses that we serve; • • ability of our clients to pay for the outsourced HR services and solutions we provide; and any resulting impact on the demand for our outsourced HR services and solutions. While the COVID-19 pandemic is continuing and even after it has subsided, we may experience materially adverse impacts to our business, operations and financial results due to any existing or continuing reduction in economic activity, including a recession or depression. The COVID-19 pandemic has resulted in a sharp decrease in employment levels throughout the United States. During the second quarter of 2020, we began to experience a decline in the number of paid WSEEs due primarily to layoffs and temporary leaves of absence, resulting in a 1.8% year-over-year decline in the average number of paid WSEEs during the second quarter of 2020. However, for the full year 2020, the average number of paid WSEEs declined 0.6% to 234,223. Further, if the adverse economic conditions relating to the COVID-19 pandemic persist, we may continue to experience a decline in our paid WSEEs. Accordingly, such declines in WSEEs would likely have a material adverse effect on our business, financial condition and results of operations. Insperity 2020 Form 10-K 20 RISK FACTORS The spread of the COVID-19 virus has changed how and when we incur health insurance costs under our health insurance contract with United. We may experience changes in quarterly levels and timing of both medical and pharmaceutical health insurance claims. For example, government imposed treatment mandates, restrictions on certain elective healthcare treatments, and changes in treatment delivery options may significantly alter our healthcare claim trends. Our ability to estimate healthcare claim trends becomes more difficult as participant utilization of healthcare services are deferred or canceled while stay-at-home orders and social distancing requirements are enacted by state and local governments. Furthermore, predicting the rate at which participants will increase utilization of healthcare services in subsequent periods once stay-at-home orders and social distancing requirements are lifted, is also difficult. In addition, as the increased number of former WSEEs elect COBRA coverage to continue their benefits, we expect an increase in claim activity levels, resulting in higher benefits costs incurred and decreased profitability. The Department of Labor and the Department of Treasury released a rule on April 29, 2020 that extends the period during which any former WSEE who became eligible for COBRA coverage in 2020 may elect such coverage and allows any former WSEEs electing COBRA coverage to defer payment of such coverage until a later date. Depending on the number of participants electing COBRA and the resulting claim activity levels, COBRA-related claims have the potential to increase total plan costs in future periods as well. The extended period during which former WSEEs may elect COBRA coverage, and their ability to defer payment of related premiums, or any future legislation that increased COBRA participation, may further result in increased costs to us and we may ultimately be unable to collect premiums from those former WSEEs or from our clients. The recent increase in U.S. unemployment levels has resulted in a significant increase in unemployment claims with state unemployment agencies. A continuous increase in unemployment claims is likely to increase state unemployment insurance tax rates. In addition, some states have the authority to increase unemployment tax rates retroactively. Any such increases, which are reflected in our comprehensive service fee, may result in client attrition due to increased prices or we may have to reduce our overall pricing, which would adversely affect our profitability, to assist clients with these additional costs. The COVID-19 economic disruptions may cause customers to have difficulty meeting their financial obligations to us or increase business failures. As a co-employer, we assume the obligation to pay the salaries, wages and related benefits and taxes of the WSEEs. An increase in the number of clients unable to pay us would result in an increase in bad debts, which could have a material adverse effect on our financial condition and results of operations. In addition, we have modified certain business and workforce practices (including those related to employee travel, employee work locations, and cancellation of physical participation in meetings, events and conferences) to conform to government restrictions and best practices encouraged by governmental and regulatory authorities. While most of our operations can be performed remotely, there is no guarantee that we will be as effective while working remotely because our team is dispersed, many employees may have additional personal needs to attend to and employees may become sick themselves and be unable to work. Further, our increased reliance on remote access to our information systems as our employees work remotely impacts our control over cybersecurity protection and service stability and performance, which increases our exposure to cybersecurity and privacy issues and to disruptions to employee productivity. We may take further actions as government authorities require or recommend or as we determine to be in the best interests of our employees, clients, partners and vendors. There is no certainty that such measures will be sufficient to mitigate the risks posed by COVID-19, in which case our ability to perform critical functions could be harmed, and we may be unable to respond to the needs of our business. The FFCRA, the CARES Act and the Consolidated Appropriations Act, 2021 created various programs and incentives to assist businesses and individuals managing through the COVID-19 pandemic. Certain of these programs and incentives have required us to make changes to our systems that manage leave, payroll and payroll-related tax calculation and reporting and invoicing and collection of service fees. In addition, various states and localities and the federal government are considering further legislation that may require further changes to our processes and systems or that may expand the coverage afforded to WSEEs under our health and workers’ compensation programs. If we are unable to timely make these changes, incur substantial additional costs in doing so, or are otherwise adversely affected by these requirements, then we may face fines, penalties, other regulatory action, or litigation relating to such failure, which could further adversely impact our PEO state licenses or registrations, our certified PEO status, our results of operations and our ability to attract and retain clients. The COVID-19 pandemic business interruptions and associated economic impact has adversely and disproportionately affected certain industries, including the oil and gas industry. The substantial decrease in the global demand for oil contributed to a significant decline in its commodity price, which has materially and adversely impacted businesses dependent on oil production, including those with operations in Texas. While our oil and gas related customers account for approximately 1% of our customer base, our Texas market accounts for approximately 20% of our revenues. The impact of Insperity 2020 Form 10-K 21 RISK FACTORS the COVID-19 pandemic on oil prices and the resulting impact on regional economies with oil-focused businesses could aggravate our risk factors for clients operating in the oil and gas sector as well as other clients who operate in the Texas market. The impact and evolving nature of the COVID-19 pandemic precludes any prediction as to its full adverse impact. Nevertheless, the COVID- 19 pandemic presents material uncertainty and risk with respect to our business, including as a result of the forgoing reasons, and may have a material adverse effect on our financial condition, results of operations, cash flows and business. Geographic market concentration makes our results of operations vulnerable to regional economic factors. Our New York, California and Texas markets accounted for approximately 10%, 15% and 20% (including 8% in Houston), respectively, of our WSEEs for the year ended December 31, 2020. Accordingly, while we have a goal of expanding in our current markets and into new markets, for the foreseeable future, a significant portion of our revenues may be subject to economic, statutory, and regulatory factors specific to New York, California and Texas. We are subject to covenants under our credit facility that may restrict our business and financing activities. Our failure to comply with these covenants may result in an acceleration of our indebtedness, which could have a material adverse effect on our business, financial condition or results of operations. Our credit facility contains, and any future indebtedness of ours likely would contain, covenants that, subject to certain exceptions, impose significant operating and financial restrictions, including restricting our ability to: • • • • • incur additional indebtedness, sell material assets, retire, redeem or otherwise reacquire our capital stock, acquire the capital stock or assets of another business, enter into new lines of business, • make investments, and • pay dividends. In addition, we are required to maintain certain financial covenants. Our ability to comply with the financial covenants may be affected by financial, business, economic, regulatory and other factors beyond our control. Our failure to comply with these covenants, or any other terms of our indebtedness, could result in a default that may limit our ability to borrow additional amounts under our credit facility, which may adversely affect our liquidity. In addition, a default may allow our lenders to accelerate our obligation to repay the outstanding amounts under our credit facility. If we were unable to repay or refinance the accelerated indebtedness on favorable terms, then our business, financial condition and results of operations would be materially adversely affected. PEO HR Outsourcing Solutions Risks We assume liability for WSEE payroll, payroll taxes, benefits costs and workers’ compensation costs and are responsible for their payment regardless of the amount billed to or paid by our clients. Under the CSA, we become a co-employer of WSEEs and assume the obligations to pay the salaries, wages and related benefits costs and payroll taxes of such WSEEs. We assume such obligations as a principal, not as an agent of the client. Our obligations include responsibility for: • payment of the salaries and wages for work performed by WSEEs, regardless of whether the client timely pays us the associated service fee • withholding and payment of federal and state payroll taxes with respect to wages and salaries reported by Insperity Insperity 2020 Form 10-K 22 RISK FACTORS • providing benefits to WSEEs even if our costs to provide such benefits exceed the fees the client pays us and the amounts collected from WSEEs • providing workers’ compensation coverage to WSEEs If a client does not pay us, or if the costs of benefits we provide to WSEEs exceed the fees a client pays us, our ultimate liability for WSEE payroll and benefits costs could have a material adverse effect on our financial condition or results of operations. Increases in health insurance costs or our inability to secure replacement health insurance coverage on competitive terms could have a material adverse effect on our business, financial condition or results of operations. Maintaining health insurance plans that cover WSEEs is a significant part of our business. Our primary health insurance contract expires on December 31, 2022, subject to cancellation by either party upon 180 days’ notice. In the event we are unable to secure replacement contracts on competitive terms, significant disruption to our business could occur. Health insurance costs are in part determined by our plans’ claims experience and comprise a significant portion of our direct costs. Our health insurance coverage is provided under policies or service contracts that are fully-insured. United is the carrier that insures the majority of our coverage. Although all of our carriers remain responsible to pay all covered claims, under our health insurance contract with United, we retain an obligation to United to fund the cost of the plan. The profitability of our PEO HR Outsourcing solutions is affected by the overall expenses associated with the cost of delivering our services, one of the largest of which is the cost of our health insurance. Our ability to accurately anticipate the expenses associated with the plans, including claims costs on a quarterly or annual basis, can impact our results of operations. If the plans experience an increase in the number or severity of claims, our associated health insurance costs could increase beyond anticipated levels, as we experienced in 2019. These costs are further impacted by a number of factors, including coverage options elected by employees, macro-economic changes, proposed and enacted regulatory changes and wide-spread health-related outbreaks. Contractual arrangements with our clients limit or delay our ability to reflect in our service fees any increases in the overall expense associated with the plans, which could substantially impair our financial condition or results of operations. Further, if the overall pricing of our services includes cost assumptions based on inaccurate forecasts of plan expenses, our profitability or our ability to attract and retain clients may be adversely impacted. As a result, if we do not accurately forecast the costs of our plans, our business, financial condition or results of operations may be materially adversely affected. For additional information related to our health insurance costs, please read Item 7. “Management’s Discussion and Analysis of Financial Condition and Results of Operations—Critical Accounting Policies and Estimates— Benefits Costs.” Health care reform could affect our health insurance plan and could lead to a significant disruption in our business. The PPACA was signed into law on March 23, 2010. The PPACA was subsequently amended on March 30, 2010 by the Reconciliation Act. The Act entails sweeping health care reforms with original staggered effective dates from 2010 through 2018, some of which were subsequently extended out as far as 2022. Some provisions in the Act still require the issuance of additional guidance from the U.S. Department of Health and Human Services (“HHS”) and the states. Beginning in 2014, a number of key provisions of the Act took effect, including the Exchanges, insurance market reforms and the imposition of excise taxes on the health insurance industry and reinsurance taxes on insurers and third-party administrators. Additionally, the pay or play penalties on Applicable Large Employers were fully phased-in by 2016. As part of the Tax Cuts and Jobs Act enacted in December 2017, the requirements that individuals maintain health insurance coverage or pay a federal tax penalty, which was known as the individual mandate, was effectively eliminated beginning in 2019. In addition, supporters in various states are advocating for adoption of healthcare-related reforms at the state level, including those states that have enacted individual mandates. Collectively, these items have the potential to significantly change the insurance marketplace for small and medium-sized businesses and how employers provide insurance to employees. Generally, the Act and subsequently issued guidance by the IRS and HHS have not addressed or in some instances are unclear as to their application in the PEO relationship or whether such provisions should be applied at the PEO or client level. Although we do not believe that the Act has had a material adverse effect on our benefit plans, business model, or operations to date, the elimination of the penalty associated with the individual mandate and subsequent changes resulting from action that may be taken at the federal or state level may impact our benefit plans, business model and future results of Insperity 2020 Form 10-K 23 RISK FACTORS operations, including repeal or repeal and replacement of the Act as has been advocated by Congressional leaders or as may result from a case pending before the U.S. Supreme Court. In future periods, changes may result in increased costs to us and could affect our ability to attract and retain clients. Additionally, contractual arrangements and competitive market conditions may limit or delay our ability to increase service fees to offset any associated potential increased costs. For additional information related to the Act, please read Item 1. “Business— Industry Regulations—Patient Protection and Affordable Care Act.” We are currently unable to determine whether potential future changes to the Act or other regulatory action, including at the state level, may adversely affect our business or market conditions. Increases in workers’ compensation costs or inability to secure replacement coverage on competitive terms could lead to a significant disruption to our business. Our workers’ compensation coverage has been provided through an arrangement with Chubb (formerly ACE American Insurance Company) since 2007. Under our current arrangement with Chubb for claims incurred on or before September 30, 2019, we have a financial responsibility to Chubb for the first $1 million layer of claims per occurrence and for claims over $1 million, up to a maximum aggregate amount of $6 million per policy year for claims that exceed the first $1 million. Effective for claims incurred on or after October 1, 2019, our financial responsibility increased as we have financial responsibility to Chubb for the first $1.5 million layer of claims per occurrence and for claims over $1.5 million, up to a maximum aggregate amount of $6 million per policy year for claims that exceed $1.5 million. Chubb bears the financial responsibility for all claims in excess of these levels. The Chubb Program is a fully insured program whereby Chubb has the responsibility to pay all claims incurred under the policies regardless of whether we satisfy our responsibilities. For additional discussion of our policy with Chubb, please read Item 7. “Management’s Discussion and Analysis of Financial Condition and Results of Operations— Critical Accounting Policies and Estimates—Workers’ Compensation Costs.” Workers’ compensation costs are a significant portion of our direct costs and contractual arrangements with our clients limit or delay our ability to reflect in our service fees any increases associated with these costs. If we were to experience an unexpected large increase in the number or severity of claims, our workers’ compensation costs could increase, which could have a material adverse effect on our results of operations or financial condition. Further, if the overall pricing of our services includes cost assumptions based on inaccurate forecasts of our workers’ compensation costs, our profitability or our ability to attract and retain clients may be adversely impacted. The current workers’ compensation coverage with Chubb expires on September 30, 2021. In the event we are unable to secure replacement coverage on competitive terms, significant disruption to our business could occur. Our ability to adjust and collect service fees for increases in unemployment tax rates may be limited. We record our SUI expense based on taxable wages and tax rates assigned by each state. SUI tax rates vary by state and are determined, in part, based on prior years’ compensation experience in each state. Certain states have indicated that 2021 unemployment tax rates will exclude COVID-19 related unemployment claims; however, the determination of which claims qualify for exclusion and the impact of such a determination on future state unemployment rates has not been clarified. Prior to the receipt of final rate notices, we estimate our expected SUI rate in those states for which rate notices have not yet been received for purposes of budgeting and pricing. In a period of adverse economic conditions, state unemployment funds may experience a significant increase in the number of unemployment claims. Accordingly, SUI rates would likely increase substantially. Some states have the ability under law to increase SUI rates retroactively to cover deficiencies in the unemployment fund. In addition, FUTA may be retroactively increased in certain states in the event the state fails to timely repay federal unemployment loans. Generally, our contractual agreements allow us to incorporate such statutory increases into our service fees upon the effective date of the rate change. However, our ability to fully adjust service fees in our billing systems and collect such increases over the remaining term of the clients’ contracts could be limited, resulting in a potential increase not being fully recovered. As a result, such increases could have a material adverse effect on our financial condition or results of operations. Many of our contracts for our PEO HR Outsourcing solutions may be canceled on short notice. Our inability to renew client contracts or attract new clients could materially and adversely affect our financial conditions or results of operations. Our standard CSA can generally be canceled by us or the client with 30 days’ notice. Accordingly, the short-term nature of the CSA makes us vulnerable to potential cancellations by existing PEO HR Outsourcing solution clients, which could Insperity 2020 Form 10-K 24 RISK FACTORS materially and adversely affect our financial condition or results of operations. During 2020, middle market accounts represented 24.4% of our average paid WSEEs and clients with an average number of WSEEs that exceed 1,000 WSEEs represented 4.7%. In the event we have large clients that terminate or an increase in terminating clients from our middle market client base, the financial impact of such an event could be significant. Also, our results of operations are dependent in part upon our ability to retain or replace our clients upon the termination or cancellation of the CSA. Our client attrition rate was approximately 18% in 2020. There can be no assurance that the number of contract cancellations will continue at these levels and such cancellations may increase in the future due to various factors, including economic conditions in the markets we operate. Clients electing to purchase our services or electing an alternative solution often do so at the beginning of the calendar year. As a result, we typically experience our largest concentration of new client additions and attrition in the first quarter of each year. Our loss of insurance coverage, the failure of our insurance carriers or increased insurance costs or deductibles could have a material adverse effect on us. As part of our PEO HR Outsourcing solutions, in addition to our health insurance carriers, we contract with other insurance carriers to provide workers’ compensation insurance and employment practices liability insurance. In addition, we obtain insurance coverage for various commercial risks in our business such as property insurance, errors and omissions insurance, cyber liability insurance, general liability insurance, fiduciary liability insurance, automobile liability insurance, and directors’ and officers’ liability insurance. The failure of any insurance carrier, such as occurred in 2001 with respect to a previous workers’ compensation insurance provider, providing such coverage could leave us exposed to uninsured risk and could have a material adverse effect on our business and results of operations. In addition, in the event that our primary health carriers in any key market make material changes to their network of healthcare providers or facilities, such as the recent temporary discontinuation of a prominent hospital network in Houston, Texas, by UnitedHealthcare in connection with their ongoing negotiations, then our ability to attract and retain clients in that market may be adversely affected, which could have a material adverse effect on our business and results of operations. Further, we have experienced an increase in insurance premiums for our corporate policies as well as an increase in the deductible amounts for which we retain liability and a decrease in coverage limits. If these premiums or deductible amounts continue to increase, or coverage limits continue to decrease we would have increased exposure with respect to costs and insurance claims, which could have a material adverse effect on our business and results of operations. A determination that a client is liable for employment taxes not paid by a PEO may discourage clients from contracting with us in the future. Under the CSA, we assume sole responsibility and liability for paying federal employment taxes imposed under the Code with respect to wages and salaries we pay our WSEEs. There are essentially three types of federal employment tax obligations: • income tax withholding requirements • FICA • FUTA Under the Code, employers have the obligation to withhold and remit the employer portion and, where applicable, the employee portion of these taxes. The SBEA clarifies that a CPEO is treated as the employer for purposes of federal payroll taxes on wages it pays to WSEEs. Most states impose similar employment tax obligations on the employer. While the CSA provides that we have sole legal responsibility for making these tax contributions, the applicable state taxing authority could conclude that such liability cannot be completely transferred to us. Accordingly, in the event that we fail to meet our tax withholding and payment obligations, the client may be held jointly and severally liable for those obligations. While this interpretive issue has not, to our knowledge, discouraged clients from enrolling with Insperity, a definitive adverse resolution of this issue may discourage clients from enrolling in the future. New and higher federal, state and local taxes could have a material adverse impact on our financial condition and results of operations. In times of economic slowdowns, the federal government and states and municipalities in which we operate may experience reductions in tax revenues and corresponding budget deficits. In response to budget shortfalls, such as those being experienced as a result of the COVID-19 pandemic, the federal government and many states and municipalities have in the Insperity 2020 Form 10-K 25 RISK FACTORS past and may in the future increase or enact new taxes on businesses operating within their tax jurisdiction, including business activity taxes and income taxes. In addition, federal, state and local taxing agencies may increase their audit activity in an effort to identify additional tax revenues. New tax assessments on our operations could result in increased costs. Further, the Biden Administration and Congressional leaders have expressed support for reviewing federal taxes and potential increases in federal tax rates for businesses. Our ability to adjust our service fees and incorporate additional tax assessments into our billing system could be limited. As a result, such higher taxes could have a material adverse impact on our financial condition or results of operations. We may be subject to liabilities for client and employee actions. As a co-employer in the PEO relationship, we assume or share many of the employer-related responsibilities and assist our clients in complying with many employment-related governmental regulations. A number of legal issues remain unresolved with respect to the co- employment arrangement between a PEO and its WSEEs, including questions concerning the ultimate liability for violations of employment, payroll, discrimination, and workplace safety laws. Our CSA establishes the contractual division of responsibilities between Insperity and our clients for various personnel management matters, including compliance with and liability under various governmental regulations. Because we act as a co-employer, we may be subject to liability for violations of various employment, payroll, discrimination, and workplace safety laws despite these contractual provisions, even if we do not participate in such violations. Although the CSA generally requires the client to indemnify us for certain liabilities attributable to the client’s conduct, we may not be able to collect on such a contractual indemnification claim and thus may be responsible for satisfying such liabilities to the extent that such liabilities are not covered or insured against under our insurance policies. In addition, WSEEs may be deemed to be our agents, which may subject us to liability for the actions of such WSEEs. Changes in federal, state and local regulation or our inability to obtain licenses under new regulatory frameworks could have a material adverse effect on our results of operations or financial condition. As a major employer, our operations are affected by numerous federal, state and local laws and regulations relating to labor, tax, benefit, insurance and employment matters. By entering into a co-employer relationship with employees assigned to work at client locations, we assume certain obligations and responsibilities of an employer under these laws. However, many of these current laws (such as the Act, ERISA and federal and state employment tax laws) do not specifically address the obligations and responsibilities of non-traditional employers such as PEOs, and the definition of “employer” under these laws is not uniform despite the SBEA having provided clarification under federal employment tax laws for CPEOs. In addition, many of the states in which we operate have not addressed the PEO relationship for purposes of compliance with applicable state laws governing the employer/employee relationship or PEO health insurance plans. Any adverse application of, or adverse legislative/regulatory response to, new or existing federal or state laws to the PEO relationship with our WSEEs and client companies could have a material adverse effect on our results of operations or financial condition. While some states do not explicitly regulate PEOs, 42 states have passed laws that have recognition, licensing, certification or registration requirements for PEOs and several other states are considering such regulation. Such laws vary from state to state, but generally provide for monitoring the fiscal responsibility of PEOs, and in some cases codify and clarify the co-employment relationship for unemployment, workers’ compensation and other purposes under state law. In addition, the SBEA provides certain benefits for companies that qualify as a CPEO. While we generally support licensing regulation because it serves to validate the PEO relationship, we may not be able to satisfy licensing requirements or other applicable regulations for all states. In addition, there can be no assurance that we will be able to renew our licenses in all states or that we will be able to maintain our CPEO designation. Certain state and federal regulators are more closely evaluating the existing regulatory framework governing money services businesses and money transmitters in their jurisdictions, particularly following the high-profile failures in 2019 of several national payroll companies. While we maintain that we are not a money services business or money transmitter, the adoption of new, or changes in interpretations of existing, state and federal money transmitter or money services business statutes, or disagreements by regulatory authorities with our interpretation of such statutes or regulations, could subject us to registration or licensing or result in limitations on our business activities until we are appropriately licensed, and such additional regulation and the actions of the regulatory authorities could have a material adverse effect on our results of operations or financial condition. These occurrences could also require changes to the manner in which we conduct some aspects of our business. In addition, should any state or federal regulators make a determination that we have operated as an unlicensed money services business or money transmitter, we could be subject to civil and criminal fines, penalties, costs, legal fees, reputational damage or other negative consequences, which could be material. Insperity 2020 Form 10-K 26 RISK FACTORS Competition and other developments in the HR services industry may impact our growth and/or profitability. The human resources services industry, including the PEO industry, is highly fragmented. Many PEOs have limited operations and fewer than 1,000 WSEEs, but there are several industry participants that are comparable to our size or larger. We also encounter competition from “fee for service” companies such as payroll processing firms, insurance companies, human resources consultants and human resources technology solutions as well as cloud-based self-service bundled human resources offerings. Our competitors include the PEO divisions of large business services companies, such as Automatic Data Processing, Inc. and Paychex, Inc., and other national PEOs such as TriNet Group, Inc. In many cases, these competitors offer a reduced service PEO offering at a lower price than our PEO HR Outsourcing solutions. We expect that as the PEO industry grows and its regulatory framework becomes better established, well organized competition with greater resources than we have may enter the PEO market, possibly including large “fee for service” companies currently providing a more limited range of services. In addition, competitors may be able to offer or develop new technology-based lower service models that may require us to make substantial investments in order to effectively compete. We offer a lower priced reduced service level PEO offering referred to as Workforce Synchronization in response to certain middle market client needs and the evolving PEO marketplace. As of December 2020, approximately 13% of our WSEEs were co-employed by Workforce Synchronization clients. In the event we were to experience a significant increase in the number of clients using the Workforce Synchronization offering or increased pricing pressures in the PEO marketplace without corresponding reductions in operating costs, our operating margins may decline, which could have a material adverse impact on our financial condition or results of operations. Technology Risks Evolving regulations, market trends and client expectations require us to constantly enhance and expand our service and technology offerings. The HR services industry is experiencing rapid technological advances to meet client expectations and expanding regulations. As new regulations are adopted, we must modify our systems to address these changes in the law, such as our recent efforts to implement the assistance provided to businesses and employees under the FFCRA and CARES Act. In order to make these types of modifications, we may be required to reallocate resources, potentially resulting in delays to planned competitive improvements to our systems. If we do not successfully or timely deploy these types of modifications, we may be unable to comply with regulations, which could subject us to penalties, damage our reputation or result in decreased sales. Further, in order to effectively compete in this environment, we must identify and predict trends, and adapt our technology and service offerings accordingly. In addition, as a larger portion of our client base falls within the middle market segment, we must also develop different technology and services to meet the more complex needs and demands of this key group. These efforts require us to devote substantial resources to develop new functionality, or to integrate third-party solutions, into our offerings. If we fail to respond successfully to these developments or we may make investments in enhancements that are not accepted by the market, then the demand for our solutions and services may diminish. Disruptions of our information technology systems could damage our reputation and materially disrupt our business operations. Many of the HR services offerings we provide to clients are conducted through a technology infrastructure using both internally developed and purchased commercial software, a wide variety of hardware infrastructure technologies, and a multi-carrier wide area network. The processing of payroll, benefits and other transactions is dependent upon this complex infrastructure, some of which is provided by third-party vendors. We must manage all of these systems, including any upgrades, replacements or enhancements, to ensure that they continue to support our services. For example, we are currently finalizing a modernization of key portions of our proprietary system for our PEO HR Outsourcing solutions as well as commencing a project to replace our customer relationship management (CRM) system. Any delays or failures resulting from network outages; planned upgrades, enhancements, or replacements of software, hardware, or other systems, including in connection with our PEO Outsourcing solutions modernization project or our CRM replacement project; or other data processing disruptions, even for a brief period of time, could result in our inability to timely process transactions. If such failures cause us to not meet client service expectations or to breach our obligations to our clients, we may lose existing clients, have difficulty attracting new clients, incur regulatory penalties or liability to our clients, or suffer other financial losses, which may have a material adverse effect on our business and financial condition. Insperity 2020 Form 10-K 27 RISK FACTORS We could be subject to reduced revenues, increased costs, liability claims, or harm to our competitive position as a result of data theft, cyberattacks or other security vulnerabilities. In connection with our HR services offerings, we collect, use, transmit and store large amounts of personal and business information about our WSEEs and clients, including payroll information, personal and business financial data, social security numbers, bank account numbers, tax information and other sensitive personal and business information. Attacks on information technology systems continue to grow in frequency and sophistication, and we and our third-party vendors are targeted by unauthorized parties using malicious tactics, code and viruses. Hardware or applications we develop or procure from third-party vendors may contain defects in design or other problems that could unexpectedly compromise the confidentiality, integrity or availability of data or our systems. Because the techniques used to obtain unauthorized access and disable or sabotage systems change frequently and may be difficult to detect for long periods of time, we and our third-party vendors may be unable to anticipate these techniques or implement adequate preventive measures. As these threats continue to evolve, we may be required to invest significant additional resources to modify and enhance our information security and controls or to investigate and remediate any security vulnerabilities. While our technology infrastructure is designed to safeguard and protect personal and business information, we have limited ability to monitor the implementation of similar safeguards by our vendors and do not have the ability to monitor such implementation by our clients or WSEEs. In addition, our services also involve the use and disclosure of personal and business information to us that could be used by a malicious party to commit identity theft or otherwise gain access to the data or funds of our clients or WSEEs. If any person, including any corporate employee, misappropriates or misuses such funds, documents or data, we may have liability for damages, and our reputation could be substantially harmed and we may have other liabilities that could have a material adverse effect on our business. Any cyberattack, unauthorized intrusion, malicious software infiltration, network disruption, corruption of data, or theft of private or other sensitive information, or inadvertent or malicious acts by our own employees, could result in the disclosure or misuse of confidential or proprietary information, and could have a material adverse effect on our business operations or that of our clients, result in liability or regulatory sanction, or cause a loss of confidence in our ability to serve clients. We may not have adequate insurance coverage to compensate us for losses from a security incident. Accordingly, the impact of a data security incident could have a material adverse effect on our business, results of operations and financial condition. Failure to comply with privacy, data protection and cybersecurity laws and regulations could have a material adverse effect on our reputation, results of operations or financial condition, or have other adverse consequences. We are subject to various federal and state laws, rules and regulations relating to the collection, use, transmission and security and privacy of personal and business information. Most states and the District of Columbia have enacted notification rules that may require notification to regulators, clients or employees in the event of a privacy breach. In addition, new laws and regulations governing data privacy and the unauthorized disclosure of confidential information pose increasingly complex compliance challenges and potentially elevate our costs. It is possible that these federal and state laws may be interpreted and applied in a manner that is inconsistent with our data practices. If so, in addition to the possibility of fines, this could result in an order requiring that we change our data practices, which could have a material adverse effect on our business. Complying with these various laws could cause us to incur substantial costs or require us to change our business practices in a manner adverse to our business. For example, we incurred additional costs and reallocated internal resources in order to comply with the requirements of the California Consumer Privacy Act of 2018 (CCPA), which became effective on January 1, 2020, and we expect to incur additional costs and reallocate additional resources when the final regulations under the CCPA are released. Other states are currently contemplating additional privacy requirements. The future enactment of more restrictive laws, rules or regulations could have a material adverse impact on us through increased costs or restrictions on our businesses and noncompliance could result in regulatory penalties and significant liability. Additionally, any failure by us to comply with these laws and regulations, including as a result of a security or privacy breach, could result in significant penalties and liabilities for us. The failure of third-party providers, such as financial institutions, data centers or cloud-service providers, could have a material adverse effect on us. In conjunction with providing services to clients, we communicate and rely on financial institutions to electronically transfer funds for the collection of our comprehensive service fee as well as the payment of wages and associated payroll tax withholdings. Communication failures or other failures involving these financial institutions, for any reason, could cause material interruptions to our operations, impact client retention, and result in significant penalties or liabilities to us. Insperity 2020 Form 10-K 28 RISK FACTORS We lease hosting facilities for our data centers at two separate facilities, located in Bryan, Texas and The Woodlands, Texas, with the Bryan facility acting as our primary data center. These facilities host the majority of our business applications, telecommunications equipment, information security infrastructure and network equipment. If our data centers experience any interruptions or outages, and our business continuity plan fails, then our operations may be materially impacted, which could result in our failure to meet our obligations to our clients, WSEEs and tax authorities, and could damage our reputation, subject us to liability and have a material adverse effect on our business and financial condition. In addition, some of our systems and services rely upon third-party technology, such as the human capital management system on which our Workforce Acceleration solution is based, the data analytics solution on which our Insperity People Analytics solution is based, and the payroll tax calculation tool that provides the rates used to calculate payroll taxes for our PEO HR Outsourcing solutions. Any failure by these service providers to deliver their services in a timely manner and in compliance with applicable laws could result in material interruptions to our operations, damage our reputation, and result in a loss of clients. Other Operational Risks Failure to integrate or realize the expected return on our acquisitions and investments could have a material adverse impact on our financial condition or results of operations. We have adopted a strategy to market and sell additional products and services within and outside of traditional PEO HR Outsourcing solutions. As part of this strategy, periodically we make strategic long-term decisions to invest in and/or acquire new companies, business units or assets. Acquiring new businesses involves a number of risks such as over-valuation of the acquired companies, entering markets or businesses in which we have no prior experience, integrating the technology, operations, and personnel, diversion of management’s attention from other business concerns and litigation resulting from the activities of the acquired company. The occurrence of one or more of these events could result in the loss of existing or prospective clients or employees, not achieving anticipated revenues or profitability, or impairment of acquired assets. Such developments could have a material impact to our financial condition, results of operations and future growth rates. Based on market conditions or changes in operating plans, the fair value of our other acquired businesses or investments could decline, requiring us to record impairment charges for all or portions of the investments. Insperity 2020 Form 10-K 29 OTHER INFORMATION Item 1B. Unresolved Staff Comments. None. Insperity 30 2020 Form 10-K PROPERTIES Item 2. Properties. We believe our current real estate and facilities are adequate for the purposes for which they are intended and provide for further expansion to accommodate our long-term growth and expansion goals. We believe that short-term leased facilities are readily available if needed to accommodate near-term needs if they arise. We will continue to evaluate the need for additional facilities based on the extent of our product and service offerings, the rate of client growth, the geographic distribution of our client base and our long-term service delivery requirements. Corporate Facilities Our corporate headquarters is located in Kingwood, Texas, in a campus-style facility. This 33-acre company-owned office campus includes 700,000 square feet of office space, including a 270,000 square foot office facility completed in February 2021 and approximately 6 acres of undeveloped land for future expansion. Development and support operations are located in the Kingwood facility. We have hosting facilities, totaling approximately 2,000 square feet, located at two separate leased facilities. The hosting facilities house the majority of our business applications, telecommunications equipment and network equipment. The facilities, located in Bryan, Texas and The Woodlands, Texas, are under lease until 2024 and 2022, respectively. Service Centers We currently have four regional service centers located in Atlanta, Dallas, Houston and Los Angeles. The Atlanta service center, which currently services approximately 35% of our WSEE base, is located in a 47,800 square foot facility under lease until 2023. The Dallas service center, which currently services approximately 24% of our WSEE base, is located in a 48,100 square foot facility under lease until 2023. In addition to the service center operations, the facility also contains sales operations. The Houston service center, which currently services approximately 20% of our WSEE base, is located on our corporate campus. The Los Angeles service center, which currently services approximately 21% of our WSEE base, is located in a 39,000 square foot facility under lease until 2029. Sales and Service Offices As of December 31, 2020, we had sales and service personnel in 65 facilities located in 40 sales markets throughout the United States. All of the facilities are leased and some are shared by multiple sales offices and/or client service personnel. As of December 31, 2020, we had 82 sales offices in these 40 markets. To take advantage of economic efficiencies, multiple sales offices may share a physical location. Each sales office is typically staffed by six to eight BPAs, a district sales manager and an office administrator. In addition, we have placed certain client service personnel in a majority of our sales markets to provide high-quality, localized service to our clients in those major markets. We expect to continue placing client service personnel in sales markets as a critical mass of clients is attained in each market. Insperity 2020 Form 10-K 31 LEGAL PROCEEDINGS Item 3.

Management’s Discussion and Analysis of Financial Condition and Results of Operations. You should read the following discussion in conjunction with our Consolidated Financial Statements and related Notes included elsewhere in this annual report. Historical results are not necessarily indicative of trends in operating results for any future period. The statements contained in this annual report that are not historical facts are forward-looking statements that involve a number of risks and uncertainties. The actual results of the future events described in such forward-looking statements in this annual report could differ materially from those stated in such forward-looking statements. Among the factors that could cause actual results to differ materially are the risks and uncertainties discussed in Item 1A. Risk Factors and the uncertainties set forth from time to time in our other public reports and filings and public statements. Executive Summary Overview Our long-term strategy is to provide the best small and medium-sized businesses in the United States with our specialized human resources service offering and to leverage our buying power and expertise to provide additional valuable services to clients. Our most comprehensive HR services offerings are provided through our Workforce Optimization and Workforce Synchronization solutions (together, our PEO HR Outsourcing solutions), which encompass a broad range of human resources functions, including payroll and employment administration, employee benefits, workers’ compensation, government compliance, performance management and training and development services. Our overall operating results can be measured in terms of revenues, gross profit or adjusted EBITDA per WSEE per month. We often use the average number of WSEEs paid during a period as our unit of measurement in analyzing and discussing our results of operations. TM ® In addition to our PEO HR Outsourcing solutions, we offer a comprehensive traditional payroll and human capital management solution, known as Workforce Acceleration . We also offer a number of other business performance solutions, including Comprehensive Traditional Payroll and Human Capital Management, Time and Attendance, Performance Management, Organizational Planning, Recruiting Services, Employment Screening, Retirement Services, and Insurance Services, many of which are offered as a cloud-based software solution. These other products or services are offered separately or with our other solutions. TM COVID-19 Pandemic The effects of the COVID-19 pandemic, including actions taken by businesses and governments, have resulted in a significant reduction in U.S. economic activity. As the duration of the pandemic and such economic impacts remain uncertain, we have planned for a range of scenarios and have modified certain business and workforce practices. To conform to government restrictions and best practices, we have taken steps designed to keep our staff safe while continuing to serve clients, including implementing remote working for all non-essential employees and providing extra safety measures at corporate facilities. To serve our clients, we have instituted a number of service offerings and developed COVID-19 resources to assist clients with obtaining government provided tax credits, tax deferrals, loans and loan forgiveness and to provide guidance to assist clients with addressing the challenges faced by employers as a result of the pandemic. These service offerings and guidance to assist clients during the pandemic included additional benefits support, remote workforce transition, monitoring and educating on regulatory changes, return to the workplace and workplace safety. The COVID-19 pandemic did not have a significant impact to our first quarter 2020 financial results due to the increased spread of, and related government and business responses to, the COVID-19 pandemic not occurring until late in the quarter. However, towards the end of the first quarter, clients began layoffs and temporary leaves of absence of WSEEs, and this trend continued into the second quarter and resulted in a 1.8% decline in year-over-year average number of paid WSEEs per month in the second quarter. In the third quarter of 2020, the number of WSEEs returning to work as well as new hires exceeded layoffs, resulting in a 1.7% sequential increase and a 3.8% year- over-year decline in the average number of paid WSEEs per month. In the fourth quarter of 2020, the average number of paid WSEEs declined 1.8% year-over-year and increased 3.2% sequentially as new client sales and rehires exceeded layoffs and client attrition. We expect overall reduced employment levels to have a negative impact on our 2021 financial results. We experienced a 10.7% decrease in the year-over-year benefits costs per covered employee during the second quarter of 2020, a 1.1% increase in the year-over-year benefits costs per covered employee during the third quarter of 2020 and a Insperity 2020 Form 10-K 39 MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS 2.4% increase in year-over-year benefits costs per covered employee during the fourth quarter of 2020. The fourth quarter 2020 increase in benefits costs per covered employee over the preceding third quarter of 2020 was due primarily to an increase in non-essential claims as a result of higher utilization and fewer deferrals or cancellations associated with the COVID-19 pandemic. For the full year 2020, we experienced a 0.5% decrease in year-over-year benefits cost per covered employee. We currently expect to experience higher costs related to COVID-19 and certain non-essential elective healthcare procedures during 2021 that had been deferred in response to COVID-19 governmental requirements or guidance related to shelter in place and similar orders, as well as additional costs related to COVID-19 treatment and COBRA medical claims. As a result, we expect that our healthcare claim costs will not be reflective of our historical quarterly claim cost trends. The COVID-19 pandemic has not had a material impact on our accrued workers’ compensation cost estimate; however, the ultimate impact of COVID-19 on our workers’ compensation program remains uncertain. As the impact of the COVID-19 pandemic continues to emerge, such impact, if any, on our workers’ compensation program will be reflected in future reporting periods. In addition, during 2020, the COVID-19 pandemic has not had a material impact on our state unemployment tax costs. However, we anticipate state unemployment tax rates will increase during 2021 and beyond due to the impact of increased unemployment claims. The majority of states have not provided 2021 unemployment tax rates to employers. Prior to the receipt of final rate notices, we estimate our expected state unemployment tax rates in those states for which rate notices have not yet been received for purposes of budgeting and pricing. Some states have indicated their intention to exclude pandemic related claims from employers’ 2021 rates. However, the determination of which claims qualify for exclusion and the impact of such a determination on the 2021 state unemployment rates has not been clarified The extent to which our future results are affected by the COVID-19 pandemic will depend on various factors and consequences beyond our control, such as the scope, duration and magnitude of the pandemic, actions by businesses and governments in response to the pandemic, including programs designed to assist small and medium-sized businesses with the economic impact of the pandemic; and the speed and effectiveness of responses to combat the virus, including the development and availability of therapeutics and vaccines. See Part I, Item 1A. “Risk Factors” for additional information. 2020 Highlights • Average number of WSEEs paid per month decreased 0.6% to 234,223, driving a 0.6% revenue decline. • We ended 2020 averaging 239,232 paid WSEEs in the fourth quarter of 2020, which represents a 1.8% decrease over the fourth quarter of 2019. We expect the average number of paid WSEEs per month to be between 232,100 and 234,400 in the first quarter 2021, which reflects the termination of a large client representing approximately 6,800 paid WSEEs. • Approximately 24.4% and 25.7% of our average paid WSEEs were in our middle market sector for the years ended December 31, 2020 and 2019, respectively, which is generally defined as companies with 150 to 5,000 WSEEs. • Gross profit increased $73.9 million, primarily due to lower healthcare utilization and lower workers’ compensation costs. • Net income and diluted earnings per share (“Diluted EPS”) decreased 8.5% and 4.3% to $138.2 million and $3.54, respectively. • Adjusted EBITDA increased 15.4% to $288.6 million. • Adjusted net income increased 7.0% to $181.3 million. • Adjusted EPS increased 11.8% to $4.64. • Our average gross profit per WSEE per month was $287 in 2020 and $259 in 2019. • Operating expenses increased 12.1% in 2020 to $612.2 million, primarily due to increased non-cash stock-based compensation expense and salaries and wages partially offset by lower travel costs. On a per WSEE per month basis, operating expenses increased from $193 in 2019 to $218 in 2020. • Our adjusted EBITDA per WSEE per month increased 17.0% from $88 in 2019 to $103 in 2020. • We ended 2020 with working capital of $172.3 million. Insperity 2020 Form 10-K 40 MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS • During 2020, we paid $61.9 million in dividends, repurchased 1.4 million shares of our common stock at a cost of $99.4 million, paid $98.2 million on capital expenditures, including $61.0 million for the construction of a new building, partially offset by borrowings of $100.0 million under our credit facility. Please read “Non-GAAP Financial Measures” for a reconciliation of adjusted EBITDA, adjusted net income, adjusted EPS and adjusted operating expenses to their most directly comparable financial measures calculated and presented in accordance with accounting principles generally accepted in the United Stated (“GAAP”). Revenues We account for our revenues in accordance with Accounting Standards Update (“ASU”) No. 2014-09, Revenue from Contracts with Customers (Topic 606). Our PEO HR Outsourcing solutions gross billings to clients include the payroll cost of each WSEE at the client location and a markup computed as a percentage of each WSEEs payroll cost. We invoice the gross billings concurrently with each periodic payroll of our WSEEs. Revenues, which exclude the payroll cost component of gross billings, and therefore, consist solely of the markup, are recognized ratably over the payroll period as WSEEs perform their service at the client worksite. This markup includes pricing components associated with our estimates of payroll taxes, benefits and workers’ compensation costs, plus a separate component related to our HR services. Revenues that have been recognized but not invoiced represent unbilled accounts receivable included in accounts receivable, net on our Consolidated Balance Sheets. Our revenues are primarily dependent on the number of clients enrolled, the resulting number of WSEEs paid each period and the number of WSEEs enrolled in our benefit plans. Because our total markup is computed as a percentage of payroll cost, certain revenues are also affected by the payroll cost of WSEEs, which may fluctuate based on the composition of the WSEE base, inflationary effects on wage levels and differences in the local economies of our markets. Direct Costs The primary direct costs associated with revenue-generating activities for our PEO HR Outsourcing solutions are: • employment-related taxes (“payroll taxes”) • costs of employee benefit plans • workers’ compensation costs Payroll taxes consist of the employer’s portion of Social Security and Medicare taxes under FICA, federal unemployment taxes and state unemployment taxes. Payroll taxes are generally paid as a percentage of payroll cost. The federal unemployment tax rates are defined by federal regulations. State unemployment tax rates are subject to claim histories and vary from state to state. Employee benefits costs are comprised primarily of health insurance premiums and claims costs (including dental and pharmacy costs), but also include costs of other employee benefits such as life insurance, vision care, disability insurance, education assistance, adoption assistance, a flexible spending account program and a work-life program. Workers’ compensation costs include administrative and risk charges paid to the insurance carrier, and claims costs, which are driven primarily by the frequency and severity of claims. Gross Profit Our gross profit per WSEE is primarily determined by our ability to accurately estimate and control direct costs and our ability to incorporate changes in these costs into the gross billings charged to PEO HR Outsourcing solutions clients, which are subject to pricing arrangements that are typically renewed annually. We use gross profit per WSEE per month as our principal measurement of relative performance at the gross profit level. Operating Expenses • Salaries, wages and payroll taxes – Salaries, wages and payroll taxes (“Salaries”) are primarily a function of the number of corporate employees, their associated average pay and any additional cash incentive compensation. Insperity 2020 Form 10-K 41 MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS Our corporate employees include client services, sales and marketing, benefits, legal, finance, information technology, administrative support personnel and those associated with our other products and services. • Stock-based compensation – Our stock-based compensation relates to the recognition of non-cash compensation expense over the requisite service period of time-vested and performance-based incentive plan awards. • Commissions – Commissions expense consists primarily of amounts paid to sales managers and other sales personnel, including BPAs as well as channel referral fees. Commissions are based on new accounts sold and a percentage of revenue generated by such personnel. • Advertising – Advertising expense primarily consists of media advertising and other business promotions in our current and anticipated sales markets, including the Insperity Invitational™ presented by UnitedHealthcare® sponsorship. • General and administrative expenses – Our general and administrative expenses primarily include: ◦ ◦ ◦ ◦ ◦ ◦ rent expenses related to our service centers and sales offices outside professional service fees related to legal, consulting, and accounting services administrative costs, such as postage, printing, and supplies employee travel and training expenses technology expenses facility repairs and maintenance costs • Depreciation and amortization – Depreciation and amortization expense is primarily a function of our capital investments in corporate facilities, service centers, sales offices, software development and technology infrastructure. Other Income (Expense) Other income (expense) includes interest charges incurred in connection with borrowings under our credit facility and interest income earned on our cash, cash equivalents, marketable securities, restricted cash and deposits. Please read “—Liquidity and Capital Resources” for additional information. Income Taxes Our provision for income taxes typically differs from the U.S. statutory rate of 21%, due primarily to state income taxes, non-deductible expenses, vesting of equity awards and various tax credits. Deferred income taxes reflect the net tax effects of temporary differences between the carrying amounts of assets and liabilities used for financial reporting purposes and the amounts used for income tax purposes. Significant items resulting in deferred income taxes include prepaid assets, accruals for workers’ compensation expenses, stock-based compensation, software development costs, accrued incentive compensation, operating lease assets and liabilities and depreciation. Changes in these items are reflected in our financial statements through a deferred income tax provision. Please read Note 7 to the Consolidated Financial statements, “Income Taxes,” for additional information. Critical Accounting Policies and Estimates The discussion and analysis of our financial condition and results of operations is based upon our Consolidated Financial Statements, which have been prepared in accordance with GAAP. The preparation of these financial statements requires our management to make estimates and judgments that affect the reported amounts of assets, liabilities, revenues and expenses, and related disclosure of contingent assets and liabilities. On an ongoing basis, we evaluate these estimates, including those related to health and workers’ compensation insurance claims experience, client bad debts, income taxes, property and equipment, goodwill and other intangibles, and contingent liabilities. We base these estimates on historical experience and on various other assumptions that we believe to be reasonable under the circumstances, the results of which form the basis for making judgments about the carrying values of assets and liabilities that are not readily apparent from other sources. Actual results may differ from these estimates. Insperity 2020 Form 10-K 42 MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS We believe the following accounting policies are critical and/or require significant judgments and estimates used in the preparation of our Consolidated Financial Statements: • Benefits costs – We provide group health insurance coverage to our WSEEs through a national network of carriers including United, UnitedHealthcare of California, Kaiser Permanente, Blue Shield of California, HMSA BlueCross BlueShield of Hawaii and Tufts, all of which provide fully insured policies or service contracts. The health insurance contract with United provides the majority of our health insurance coverage. As a result of certain contractual terms, we have accounted for this plan since its inception using a partially self-funded insurance accounting model. Accordingly, we record the costs of the United plan, including an estimate of the incurred claims, taxes and administrative fees (collectively the “Plan Costs”), as benefits expense in the Consolidated Statements of Operations. The estimated incurred claims are based upon: (1) the level of claims processed during the quarter; (2) estimated completion rates based upon recent claim development patterns under the plan; and (3) the number of participants in the plan, including both active and COBRA enrollees. Each reporting period, changes in the estimated ultimate costs resulting from claim trends, plan design and migration, participant demographics and other factors are incorporated into the benefits costs. Effective January 1, 2020, we entered into an arrangement whereby our financial responsibility is limited to the first $1 million of paid claims per claimant per year. Additionally, since the plan’s inception, under the terms of the contract, United establishes cash funding rates 90 days in advance of the beginning of a reporting quarter. If the Plan Costs for a reporting quarter are greater than the premiums paid and owed to United, a deficit in the plan would be incurred and we would accrue a liability for the excess costs on our Consolidated Balance Sheets. On the other hand, if the Plan Costs for the reporting quarter are less than the premiums paid and owed to United, a surplus in the plan would be incurred and we would record an asset for the excess premiums in our Consolidated Balance Sheets. The terms of the arrangement with United require us to maintain an accumulated cash surplus in the plan of $9.0 million, which is reported as long-term prepaid insurance. As of December 31, 2020, Plan Costs were more than the net premiums paid and owed to United by $6.0 million. As this amount is less than the agreed-upon $9.0 million surplus maintenance level, the $15.0 million difference is included in accrued health insurance costs, a current liability, in our Consolidated Balance Sheets. In addition, the premiums owed to United at December 31, 2020, were $11.7 million, which is also included in accrued health insurance costs, a current liability, on our Consolidated Balance Sheets. We believe that recent claim development patterns are representative of incurred but not reported claims costs during the reporting period. The estimated completion rate used to compute incurred but not reported claims involves a significant level of judgment. Accordingly, an increase (or decrease) in the completion rate used to estimate the incurred claims would result in an increase (or decrease) in benefits costs and net income would decrease (or increase) accordingly. The following table illustrates the sensitivity of changes in the completion rate on our estimate of total benefits costs of $2.0 billion in 2020: Change in Completion Rate (2.5)% (1.0)% 1.0% 2.5% Change in Benefits Costs (in thousands) Change in Net Income (in thousands) $ $ (19,572) (7,829) 7,829 19,572 14,293 5,717 (5,717) (14,293) • Workers’ compensation costs – Since 2007, our workers’ compensation coverage has been provided through an arrangement with Chubb. The Chubb Program is fully insured in that Chubb has the responsibility to pay all claims incurred under the policy regardless of whether we satisfy our responsibilities. Under the Chubb Program for claims incurred on or before September 30, 2019, we have financial responsibility to Chubb for the first $1 million layer of claims per occurrence and, for claims over $1 million, up to a maximum aggregate amount of $6 million per policy year for claims that exceed $1 million. Effective for claims incurred on or after October 1, 2019, we have financial responsibility to Chubb for the first $1.5 million layer of claims per occurrence and, for claims over $1.5 million, up to a maximum aggregate amount of $6 million per policy year for claims that exceed $1.5 million. Insperity 2020 Form 10-K 43 MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS Because we bear the financial responsibility for claims up to the levels noted above, such claims, which are the primary component of our workers’ compensation costs, are recorded in the period incurred. Workers’ compensation insurance includes ongoing health care and indemnity coverage whereby claims are paid over numerous years following the date of injury. Accordingly, the accrual of related incurred costs in each reporting period includes estimates, which take into account the ongoing development of claims and therefore requires a significant level of judgment. We utilize a third-party actuary to estimate our loss development rate, which is primarily based upon the nature of WSEEs’ job responsibilities, the location of WSEEs, the historical frequency and severity of workers’ compensation claims, and an estimate of future cost trends. Each reporting period, changes in the actuarial assumptions resulting from changes in actual claims experience and other trends are incorporated into our workers’ compensation claims cost estimates. During the years ended December 31, 2020 and 2019, we reduced accrued workers’ compensation costs by $42.1 million and $31.7 million, respectively, for changes in estimated losses related to prior reporting periods. Workers’ compensation cost estimates are discounted to present value at a rate based upon the U.S. Treasury rates that correspond with the weighted average estimated claim payout period (the average discount rate was 0.6% in 2020 and 1.9% in 2019) and are accreted over the estimated claim payment period and included as a component of direct costs in our Consolidated Statements of Operations. Our claim trends could be greater than or less than our prior estimates, in which case we would revise our claims estimates and record an adjustment to workers’ compensation costs in the period such determination is made. If we were to experience any significant changes in actuarial assumptions, our loss development rates could increase (or decrease), which would result in an increase (or decrease) in workers’ compensation costs and a resulting decrease (or increase) in net income reported in our Consolidated Statements of Operations. The following table illustrates the sensitivity of changes in the loss development rate on our estimate of workers’ compensation costs totaling $65.8 million in 2020: Change in Loss Development Rate Change in Workers’ Compensation Costs (in thousands) Change in Net Income (in thousands) $ (5.0)% (2.5)% 2.5% 5.0% $ (4,165) (2,082) 2,082 4,165 3,040 1,520 (1,520) (3,040) At the beginning of each policy period, the workers’ compensation insurance carrier establishes monthly funding requirements comprised of premium costs and funds to be set aside for payment of future claims (“claim funds”). The level of claim funds is primarily based upon anticipated WSEE payroll levels and expected workers’ compensation loss rates, as determined by the insurance carrier. Monies funded into the program for incurred claims expected to be paid within one year are recorded as restricted cash, a short-term asset, while the remainder of claim funds are included in deposits, a long-term asset in our Consolidated Balance Sheets. In 2020, we received $28.2 million for the return of excess claim funds related to the workers’ compensation program, which decreased deposits. As of December 31, 2020, we had restricted cash of $45.5 million and deposits of $186.3 million. We have estimated and accrued $240.8 million in incurred workers’ compensation claim costs as of December 31, 2020. Our estimate of incurred claim costs expected to be paid within one year is recorded as accrued workers’ compensation costs and is included in short-term liabilities, while our estimate of incurred claim costs expected to be paid beyond one year is included in long-term liabilities in our Consolidated Balance Sheets. • Contingent liabilities – We accrue and disclose contingent liabilities in our Consolidated Financial Statements in accordance with ASC 450-10, Contingencies. GAAP requires accrual of contingent liabilities that are considered probable to occur and that can be reasonably estimated. For contingent liabilities that are considered reasonably possible to occur, financial statement disclosure is required, including the range of possible loss if it can be reasonably determined. From time to time, we disclose in our financial statements issues that we believe are reasonably possible to occur, although we cannot determine the range of possible loss in all cases. As issues develop, we evaluate the probability of future loss and the potential range of such losses. If such evaluation were to determine that a loss was probable and the loss could be reasonably estimated, we would be required to accrue our estimated loss, which would reduce net income in the period that such determination was made. Insperity 2020 Form 10-K 44 MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS • Allowance for doubtful accounts – We maintain an allowance for doubtful accounts for estimated losses resulting from the inability of our clients to pay their comprehensive service fees. We believe that the success of our business is heavily dependent on our ability to collect these comprehensive service fees for several reasons, including: • • • the fact that we are at risk for the payment of our direct costs and WSEE payroll costs regardless of whether our clients pay their comprehensive service fees the large volume and dollar amount of transactions we process the periodic and recurring nature of payroll, upon which the comprehensive service fees are based To mitigate this risk, we have established very tight credit policies. We generally require our PEO HR Outsourcing solutions clients to pay their comprehensive service fees no later than the same day as the applicable payroll date. In addition, we generally maintain the right to terminate the CSA and associated WSEEs or to require prepayment, letters of credit or other collateral if a client’s financial position deteriorates or if the client does not pay the comprehensive service fee. As a result of these efforts, losses related to client nonpayment have historically been low as a percentage of revenues. However, if our clients’ financial conditions were to deteriorate rapidly, resulting in nonpayment, our accounts receivable balances could grow and we could be required to provide for additional allowances, which would decrease net income in the period that such determination was made. New Accounting Pronouncements We believe that we have implemented the accounting pronouncements with a material impact on our financial statements and do not believe there are any new or pending pronouncements that will materially impact our financial position or results of operations. Please read Note 1 “Accounting Policies,” to the Consolidated Financial Statements for additional information.

The net gain (loss) in our client base declined compared to 2019 as we have seen layoffs and furloughs exceeding WSEEs returning to work or otherwise hired. We have also seen certain clients hire significant numbers of WSEEs, while others have experienced significant layoffs. Average client retention declined from 85% in 2019 to 82% in 2020. • During 2019, while the average number of WSEEs paid increased 12.6%, the number of WSEEs paid from new client sales decreased over 2018. In addition, the net change in existing clients and client retention also decreased compared to 2018. 2020 Compared to 2019 Our revenues for 2020 were $4.3 billion, a decrease of 0.6%, primarily due to the following: • Average WSEEs paid decreased 0.6%. • Revenues per WSEE per month was essentially flat with only a decrease of 0.1%, or $2, as 3.0% higher average pricing was partially offset by $121.3 million, or $43 per WSEE per month, in FICA deferral elections by clients and credits pursuant to the CARES Act and the FFCRA. These deferral elections also reduced our direct costs and Insperity 2020 Form 10-K 47 MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS therefore had no net effect on our gross profit. In addition, during the second quarter of 2020, we reduced revenue by $11.6 million for client comprehensive service fee credits applied generally on a WSEE basis across our active client base to assist clients in addressing the unprecedented economic impact of the COVID-19 pandemic. 2019 Compared to 2018 Our revenues for 2019 were $4.3 billion, an increase of 12.7%, primarily due to the following: • Average WSEEs paid increased 12.6% • Revenues per WSEE per month increased 0.1%, or $1 We provide our PEO HR Outsourcing solutions to small and medium-sized businesses in strategically selected markets throughout the United States. PEO HR Outsourcing solutions revenue distribution by region follows: PEO HR Outsourcing Solutions Revenue by Region (in thousands) The percentage of total PEO HR Outsourcing solutions revenues in our significant markets include the following: Significant Markets Gross Profit In determining the pricing of the markup component of our gross billings, we take into consideration our estimates of the Insperity 2020 Form 10-K 48 MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS costs directly associated with our WSEEs, including payroll taxes, benefits and workers’ compensation costs, plus an acceptable gross profit margin. As a result, our gross profit per WSEE and our operating results are significantly impacted by our ability to accurately estimate, control and manage our direct costs relative to the revenues derived from the markup component of our gross billings. Our gross billings charged to our PEO HR Outsourcing solutions clients are subject to pricing arrangements that are typically renewed annually. We use gross profit per WSEE per month as our principal measurement of relative performance at the gross profit level. 2020 Compared to 2019 Our pricing objectives attempt to achieve a level of revenue per WSEE that matches or exceeds changes in primary direct costs and operating expenses. Our revenues per WSEE per month decreased $2 due to higher average pricing, which was offset by client FICA deferral elections and tax credits pursuant to the CARES Act and FFCRA in 2020. Our direct costs per WSEE per month decreased $30 due primarily to changes in our direct costs components as described below. The net decrease in direct costs between 2020 and 2019 attributable to changes in cost estimates for benefits and workers’ compensation totaled $12.9 million as discussed below. The primary direct cost components changed as follows: Benefits costs • • The cost of group health insurance and related employee benefits increased $11 per WSEE per month, but decreased 0.5% on a per covered employee basis due primarily to a decrease in claims as a result of lower utilization and the deferral of nonessential healthcare procedures in response to COVID-19 governmental requirements or guidance. The percentage of WSEEs covered under our health insurance plan was 67.9% in 2020 and 66.5% in 2019. • Reported results include changes in estimated claims run-off related to prior periods, which was a decrease in costs of $0.2 million, but remained flat on a per WSEE per month basis, in 2020 compared to an increase in costs of $2.3 million, or $1 per WSEE per month, in 2019. Insperity 2020 Form 10-K 49 MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS Please read “—Critical Accounting Policies and Estimates—Benefits Costs” for a discussion of our accounting for health insurance costs. Workers’ compensation costs Our continued discipline around our client selection, safety and claims management contributed to the reduction in our cost per WSEE and, as a result, has allowed for claims within our policy periods to be closed out at amounts below our original costs estimates. • Workers’ compensation costs decreased 19.7%, or $6 per WSEE per month, in 2020 compared to 2019. • • As a percentage of non-bonus payroll cost, workers’ compensation costs in 2020 were 0.32% compared to 0.41% in 2019. As a result of closing out claims incurred in prior periods at lower than expected costs, we recorded a reduction in workers’ compensation costs of $42.1 million, or 0.20% of non-bonus payroll costs, in 2020 compared to a reduction of $31.7 million, or 0.16% of non-bonus payroll costs, in 2019. The 2020 period costs include the impact of a 0.6% discount rate used to accrue workers’ compensation loss claims, compared to a 1.9% discount rate used in the 2019 period. Please read “—Critical Accounting Policies and Estimates—Workers’ Compensation Costs” for a discussion of our accounting for workers’ compensation costs. Payroll tax costs • • Payroll taxes decreased 6.9%, or $34 per WSEE per month, due primarily to $121.3 million in FICA deferral elections and tax credits by clients pursuant to the CARES Act and FFCRA. In addition, IRS tax reporting changes in 2020 eliminated PEO reporting of payroll taxes for self-employed owners. These reductions were partially offset by a 4.3% increase in payroll costs. Payroll taxes as a percentage of payroll cost were 6.0% in 2020 and 6.7% in 2019. 2019 Compared to 2018 The net decrease in direct costs between 2019 and 2018 attributable to changes in cost estimates for benefits and workers’ compensation totaled $9.3 million as discussed below. The primary direct cost components changed as follows: Benefits costs • • The cost of group health insurance and related employee benefits increased $12 per WSEE per month, or 4.0%, on a per covered employee basis due primarily to an increase in the number of large individual healthcare claimants in 2019. The percentage of WSEEs covered under our health insurance plan was 66.5% in 2019 and 68.0% in 2018. • Reported results include changes in estimated claims run-off related to prior periods, which was an increase in costs of $2.3 million, or $1 per WSEE per month, in 2019 compared to a decrease in costs of $1.3 million, or $1 per WSEE per month, in 2018. Please read “—Critical Accounting Policies and Estimates—Benefits Costs” for a discussion of our accounting for health insurance costs. Workers’ compensation costs Our continued discipline around our client selection, safety and claims management contributed to the reduction in our cost per WSEE and, as a result, has allowed for claims within our policy periods to be closed out at amounts below our original costs estimates. • Workers’ compensation costs decreased 4.7%, or $5 per WSEE per month, in 2019 compared to 2018. Insperity 2020 Form 10-K 50 MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS • • As a percentage of non-bonus payroll cost, workers’ compensation costs in 2019 were 0.41% compared to 0.49% in 2018. As a result of closing out claims incurred in prior periods at lower than expected costs, we recorded a reduction in workers’ compensation costs of $31.7 million, or 0.16% of non-bonus payroll costs, in 2019 compared to a reduction of $18.8 million, or 0.11% of non-bonus payroll costs, in 2018. The 2019 period costs include the impact of a 1.9% discount rate used to accrue workers’ compensation loss claims, compared to a 2.6% discount rate used in the 2018 period. Please read “—Critical Accounting Policies and Estimates—Workers’ Compensation Costs” for a discussion of our accounting for workers’ compensation costs. Payroll tax costs • • Payroll taxes increased 14.2%, or $8 per WSEE per month, due primarily to a 14.5% increase in payroll costs partially offset by lower unemployment tax rates in 2019. Payroll taxes as a percentage of payroll cost were 6.7% in both 2019 and 2018. Operating Expenses 2020 Compared to 2019 The following table presents certain information related to our operating expenses: (in thousands, except per WSEE) Salaries Stock-based compensation Commissions Advertising General and administrative Depreciation and amortization Total operating expenses 2020 353,273 $ 60,145 32,835 21,556 113,167 31,189 612,165 $ $ $ $ 2019 317,124 23,993 31,420 21,603 123,438 28,723 546,301 Year Ended December 31, % Change 2020 WSEE 2019 % Change 11.4 % $ 150.7 % 4.5 % (0.2)% (8.3)% 8.6 % 12.1 % $ 126 $ 21 12 8 40 11 218 $ 112 8 11 8 44 10 193 12.5 % 162.5 % 9.1 % — (9.1)% 10.0 % 13.0 % Operating expenses for 2020 increased 12.1% to $612.2 million compared to $546.3 million in 2019. Operating expenses per WSEE per month for 2020 increased 13.0% to $218 compared to $193 in 2019. • • Salaries of corporate and sales staff increased 11.4% to $353.3 million, or $14 per WSEE per month, compared to 2019. The increase was primarily due to a 4.1% increase in headcount, including a 9.3% increase in total BPAs in 2020 and higher incentive compensation expense during 2020 related to better than expected 2020 operating results compared to lower than expected 2019 operating results. Stock-based compensation increased 150.7% to $60.1 million, or $13 per WSEE per month, compared to 2019. The increase was primarily due to an increase in the number of stock awards anticipated to be earned related to performance-based awards granted under our short-term and long-term incentive plans based on our higher than expected operating results in 2020 compared to lower than expected operating results in 2019. In addition, 2020 contains the acceleration of stock-based compensation expense for employees who meet the retirement eligibility requirements for continued vesting. Please read Note 1 “Accounting Policies” and Note 9 “Incentive Plans,” to the Consolidated Financial Statements for additional information. • Commissions expense increased 4.5% to $32.8 million, or $1 per WSEE per month, compared to 2019. Commissions are primarily due to commissions associated with our PEO HR Outsourcing solutions, including an increase in the amount of sales channel referral fees paid during 2020. Insperity 2020 Form 10-K 51 MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS • Advertising expense was flat compared to 2019, as a decrease in trade shows and events due to COVID-19 was partially offset by an increase in internet and radio advertising. • General and administrative expenses decreased 8.3% to $113.2 million, or $4 per WSEE per month, compared to 2019. The decrease was primarily due to reductions in travel and training costs in response to the COVID-19 pandemic, partially offset by an increase in technology licensing costs, corporate insurance and rent expense. • Depreciation and amortization expense increased 8.6% to $31.2 million, or $1 per WSEE per month, compared to 2019. The increase was primarily due to increased capital expenditures related to software development costs and sales office expansions. 2019 Compared to 2018 The following table presents certain information related to our operating expenses: (in thousands, except per WSEE) Salaries Stock-based compensation Commissions Advertising General and administrative Depreciation and amortization Total operating expenses 2019 317,124 $ 23,993 31,420 21,603 123,438 28,723 546,301 $ $ $ $ 2018 301,027 20,425 28,957 18,554 111,068 22,842 502,873 Year Ended December 31, % Change 2019 WSEE 2018 % Change 5.3 % $ 17.5 % 8.5 % 16.4 % 11.1 % 25.7 % 8.6 % $ 112 $ 8 11 8 44 10 193 $ 120 8 12 7 45 9 201 (6.7)% — (8.3)% 14.3 % (2.2)% 11.1 % (4.0)% Operating expenses for 2019 increased 8.6% to $546.3 million compared to $502.9 million in 2018. Operating expenses per WSEE per month for 2019 decreased 4.0% to $193 compared to $201 in 2018. • • Salaries of corporate and sales staff increased 5.3% to $317.1 million, but decreased $8 on a per WSEE per month basis, compared to 2018. The increase was primarily due to an 11.4% increase in headcount, including a 12.8% increase in total BPAs in 2019, partially offset by the non-recurrence of a $9.3 million one-time tax reform bonus paid in the first quarter of 2018 and lower incentive compensation expense during 2019. Stock-based compensation increased 17.5% to $24.0 million, but remained flat on a per WSEE per month basis, compared to 2018. This increase was primarily due to the acceleration of restricted stock awards and associated expense into the fourth quarter of 2017 that were originally scheduled to vest in the first quarter of 2018. Please read Note 1 “Accounting Policies” and Note 9 “Incentive Plans,” to the Consolidated Financial Statements for additional information. • Commissions expense increased 8.5% to $31.4 million, but decreased $1 on a per WSEE per month basis, compared to 2018. Commissions are primarily due to commissions associated with the growth in our PEO HR Outsourcing solutions, including an increase in the amount of sales channel referral fees paid in 2019. • Advertising expense increased 16.4% to $21.6 million, or $1 per WSEE per month, compared to 2018. The increase was primarily due to an increase in advertising and business promotions. • General and administrative expenses increased 11.1% to $123.4 million, but decreased $1 on a per WSEE per month basis, compared to 2018. The increase was primarily due to increased travel and training expenses associated with the increase in BPAs and technology licensing and maintenance costs. • Depreciation and amortization expense increased 25.7% to $28.7 million, or $1 per WSEE per month, compared to 2018. The increase was primarily due to increased capital expenditures related to software development costs and sales office expansions. Other Income (Expense) Insperity 2020 Form 10-K 52 MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS Other income (expense), was expense of $5.4 million in 2020, income of $3.0 million in 2019 and income of $3.3 million in 2018. In 2020, the decrease in other income was due to a decrease in interest income on our marketable securities investments and workers’ compensation deposits and a slight increase in interest expense related to the higher outstanding balance on our credit facility. In 2019, higher interest income earnings on our investments was offset by higher interest expense on our outstanding debt.

Income Tax Expense Our effective income tax rate was 27.0% in 2020, 20.3% in 2019 and 25.7% in 2018. During 2020, we incurred federal and state income tax expense of $51.0 million on pre-tax income of $189.3 million. Our provision for income taxes differed from the U.S. statutory rate of 21% primarily due to state income taxes and non-deductible expenses, offset by a $2.1 million tax benefit associated with equity compensation. During 2019, we incurred federal and state income tax expense of $38.5 million on pre-tax income of $189.6 million. Our provision for income taxes differed from the U.S. statutory rate of 21% primarily due to state income taxes and non-deductible expenses, offset by a $14.6 million tax benefit associated with equity compensation. During 2018, we incurred federal and state income tax expense of $46.9 million on pre-tax income of $182.4 million. Our provision for income taxes differed from the U.S. statutory rate of 21% primarily due to state income taxes and non-deductible expenses, offset by $3.9 million of tax benefits associated with equity compensation.

Insperity 2020 Form 10-K 53 MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS Non-GAAP Financial Measures Non-GAAP financial measures are not prepared in accordance with GAAP and may be different from non-GAAP financial measures used by other companies. Non-GAAP financial measures should not be considered as a substitute for, or superior to, measures of financial performance prepared in accordance with GAAP. Investors are encouraged to review the reconciliation of the non-GAAP financial measures used to their most directly comparable GAAP financial measures as provided in the tables below. Non-GAAP Measure Non-bonus payroll cost Definition Non-bonus payroll cost is a non-GAAP financial measure that excludes the impact of bonus payrolls paid to our WSEEs. Benefit of Non-GAAP Measure Our management refers to non-bonus payroll cost in analyzing, reporting and forecasting our workers’ compensation costs. Bonus payroll cost varies from period to period, but has no direct impact to our ultimate workers’ compensation costs under the current program. We include these non-GAAP financial measures because we believe they are useful to investors in allowing for greater transparency related to the costs incurred under our current workers’ compensation program. Adjusted cash, cash equivalents and marketable securities Excludes funds associated with: • federal and state income tax withholdings, • employment taxes, • other payroll deductions, and • client prepayments. Adjusted operating expense Represents operating expenses excluding the impact of the following: • costs associated with a one-time tax reform bonus paid to corporate employees. EBITDA Represents net income computed in accordance with GAAP, plus: • interest expense, • income tax expense, and • depreciation and amortization expense. Adjusted EBITDA Represents EBITDA plus: Adjusted net income Adjusted EPS • non-cash stock based compensation, • costs associated with a one-time tax reform bonus paid to corporate employees, and • charitable donations to Hurricane Harvey relief efforts. Represents net income computed in accordance with GAAP, excluding: • non-cash stock based compensation, • costs associated with a one-time tax reform bonus paid to corporate employees, and • charitable donations to Hurricane Harvey relief efforts. Represents diluted net income per share computed in accordance with GAAP, excluding: • non-cash stock based compensation, • costs associated with a one-time tax reform bonus paid to corporate employees, and • charitable donations to Hurricane Harvey relief efforts. We believe that the exclusion of the identified items helps us reflect the fundamentals of our underlying business model and analyze results against our expectations, against prior periods, and to plan for future periods by focusing on our underlying operations. We believe that the adjusted results provide relevant and useful information for investors because they allow investors to view performance in a manner similar to the method used by management and improves their ability to understand and assess our operating performance. Adjusted EBITDA is used by our lenders to assess our leverage and ability to make interest payments.

Liquidity and Capital Resources We periodically evaluate our liquidity requirements, capital needs and availability of resources in view of, among other things, our expansion plans, stock repurchases, potential acquisitions, debt service requirements and other operating cash needs. To meet short-term liquidity requirements, which are primarily the payment of direct costs and operating expenses, we rely primarily on cash from operations. Longer- term projects, large stock repurchases or significant acquisitions may be financed with debt or equity. We have a $500 million credit facility (“Facility”) with a syndicate of financial institutions. The Facility is available for working capital and general corporate purposes, including acquisitions and stock repurchases. We have in the past sought, and may in the future seek, to raise additional capital or take other steps to increase or manage our liquidity and capital resources. We had $589.4 million in cash, cash equivalents and marketable securities at December 31, 2020, of which approximately $342.0 million was payable in early January 2021 for withheld federal and state income taxes, employment taxes and other payroll deductions, and $35.3 million were client prepayments that were payable in January 2021. During 2020, we borrowed $100.0 million under the Facility, which increased working capital. At December 31, 2020, we had working capital of $172.3 million compared to $105.7 million at December 31, 2019. The increase in working capital reflects, in part, cash flow from operations and borrowings under our Facility, offset by share repurchases, dividends and capital expenditures. We currently believe that our cash on hand, marketable securities, cash flows from operations and availability under our Facility will be adequate to meet our liquidity requirements for 2021. We intend to rely on these same sources, as well as public and private debt or equity financing, to meet our longer-term liquidity and capital needs, which we are monitoring in light of the significant uncertainty created by the COVID-19 pandemic. At December 31, 2020, we had outstanding letters of credit and borrowings totaling $370.4 million under the Facility. Please read Note 6 to the Consolidated Financial Statements, “Long-Term Debt,” for additional information. Cash Flows from Operating Activities Our net cash flows from operating activities in 2020 were $346.4 million. Our primary source of cash from operations is the comprehensive service fee and payroll funding we collect from our PEO HR Outsourcing solutions clients. Cash and cash equivalents, and thus our reported cash flows from operating activities, are significantly impacted by various external and internal factors, which are reflected in part by the changes in our balance sheet accounts. These include the following: Insperity 2020 Form 10-K 57 MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS • Timing of client payments / payroll taxes – We typically collect our comprehensive service fee, along with the client’s payroll funding, from clients no later than the same day as the payment of WSEE payrolls and associated payroll taxes. Therefore, the last business day of a reporting period has a substantial impact on our reporting of operating cash flows. For example, many WSEEs are paid on Fridays and at month-end; therefore, operating cash flows decrease in the reporting periods that end on a Friday. In the year ended December 31, 2020, the last business day of the reporting period ended on a Thursday, client prepayments were $35.3 million and amounts payable for withheld federal and state income taxes, employment taxes and other payroll deductions was $342.0 million. In the period ended December 31, 2019, which ended on a Tuesday, client prepayments were $59.6 million and amounts payable for withheld federal and state income taxes, employment taxes and other payroll deductions was $234.6 million. • Workers’ compensation plan funding – In 2020 and 2019, we received $28.2 million and $18.8 million, respectively, for the return of excess claim funds related to the workers’ compensation program, which resulted in an increase in working capital. • Medical plan funding – Our health care contract with United establishes participant cash funding rates 90 days in advance of the beginning of a reporting quarter. Therefore, changes in the participation level of the United plan have a direct impact on our operating cash flows. In addition, changes to the funding rates, which are determined solely by United based primarily upon recent claim history and anticipated cost trends, also have a significant impact on our operating cash flows. As of December 31, 2020, Plan Costs were more than the net premiums paid and owed to United by $6.0 million, which is $15.0 million less than our agreed-upon $9.0 million surplus maintenance level. The $15.0 million difference is therefore reflected as a current liability and $9.0 million is reflected as a long-term asset on our Consolidated Balance Sheets at December 31, 2020. In addition, the premiums owed to United at December 31, 2020, were $11.7 million, which is included in accrued health insurance costs, a current liability, on our Consolidated Balance Sheets. • Operating results – Our adjusted net income has a significant impact on our operating cash flows. Our adjusted net income increased 7.0% to $181.3 million in 2020 from $169.4 million in 2019. Please read “Results of Operations.” Cash Flows from Investing Activities Our net cash flows used in investing activities were $98.6 million during 2020, primarily due to $98.2 million in property and equipment purchases, which included $61.0 million related to our corporate office expansion. Cash Flows from Financing Activities Our net cash flows used in financing activities were $53.6 million during 2020. We repurchased $99.4 million in stock and paid $61.9 million in dividends, offset by borrowings of $100.0 million under our Facility. Please read Note 6 to the Consolidated Financial Statements, “Long- Term Debt,” for additional information. Seasonality, Inflation and Quarterly Fluctuations Our quarterly earnings are impacted by the seasonal nature of our medical claims costs and payroll taxes. Typically, medical claims costs tend to increase throughout the year with the fourth quarter being the period with the highest costs, which has a negative impact on our fourth quarter earnings. This trend is primarily the result of many WSEEs’ medical plan deductibles being fully met by the fourth quarter, which increases our liability with respect to those claims. We have also experienced variability on a quarterly basis in medical claims costs based on the unpredictable nature of large claims and the COVID-19 pandemic effect on healthcare utilization patterns. Payroll taxes and associated billings are computed based on an employee’s annual taxable wage base. The annual payroll tax wage bases are frequently met in the first two quarters of each year depending on the employee’s compensation levels. As a result, the gross profit contribution from payroll taxes is typically higher in the first two quarters and declines in the latter half of each year. These historical trends may change and other seasonal trends may develop in the future. For further information related to our health insurance costs, please read “—Critical Accounting Policies and Estimates—Benefits Costs.” We believe the effects of inflation have not had a significant impact on our results of operations or financial condition. Insperity 2020 Form 10-K 58 QUANTITIVE AND QUALITATIVE DISCLOSURES Item 7A. Quantitative and Qualitative Disclosures About Market Risk. We are primarily exposed to market risks from fluctuations in interest rates and the effects of those fluctuations on the market values of our cash equivalent short-term investments and our available-for-sale marketable securities. In addition, borrowings under our Facility bear interest at a variable market rate. As of December 31, 2020, we had outstanding letters of credit and borrowings totaling $370.4 million under the Facility. Please read Note 6 to the Consolidated Financial Statements, “Long-Term Debt,” for additional information. Our cash equivalent short-term investments consist primarily of overnight investments, which are not significantly exposed to interest rate risk, except to the extent that changes in interest rates will ultimately affect the amount of interest income earned on these investments. Our available-for-sale marketable securities are subject to interest rate risk because these securities generally include a fixed interest rate. As a result, the market values of these securities are affected by changes in prevailing interest rates. We attempt to limit our exposure to interest rate risk primarily through diversification and low investment turnover. Our investment policy is designed to maximize after-tax interest income while preserving our principal investment. As a result, our marketable securities consist of tax-exempt short and intermediate-term debt securities, which are primarily pre-refunded municipal bonds that are secured by escrow funds containing U.S. Government Securities.

INDEX TO CONSOLIDATED FINANCIAL STATEMENTS Report of Independent Registered Public Accounting Firm Management’s Report on Internal Control Report of Independent Registered Public Accounting Firm on Internal Control over Financial Reporting Consolidated Balance Sheets Consolidated Statements of Operations Consolidated Statements of Comprehensive Income Consolidated Statements of Stockholders’ Equity Consolidated Statements of Cash Flows Notes to Consolidated Financial Statements F-2 F-5 F-6 F-7 F-8 F-9 F-10 F-11 F-13 Insperity 2020 Form 10-K F-1 CONSOLIDATED FINANCIAL STATEMENTS REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM To the Stockholders and the Board of Directors of Insperity, Inc. Opinion on the Financial Statements We have audited the accompanying consolidated balance sheets of Insperity, Inc. (the Company) as of December 31, 2020 and 2019, and the related consolidated statements of operations, comprehensive income, stockholders' equity and cash flows for each of the three years in the period ended December 31, 2020, and the related notes (collectively referred to as the “ consolidated financial statements”). In our opinion, the consolidated financial statements present fairly, in all material respects, the financial position of the Company at December 31, 2020 and 2019, and the results of its operations and its cash flows for each of the three years in the period ended December 31, 2020, 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, 2020, based on criteria established in Internal Control-Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (2013 framework), and our report dated February 11, 2021 expressed an unqualified opinion thereon. Basis for Opinion These financial statements are the responsibility of the Company's management. Our responsibility is to express an opinion on the Company’s 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 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 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 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 financial statements. We believe that our audits provide a reasonable basis for our opinion. Critical Audit Matters The critical audit matters communicated below are matters arising from the current period audit of the financial statements that were communicated or required to be communicated to the audit committee and that: (1) relate to accounts or disclosures that are material to the financial statements and (2) involved our especially challenging, subjective, or complex judgments. The communication of critical audit matters does not alter in any way our opinion on the consolidated financial statements, taken as a whole, and we are not, by communicating the critical audit matters below, providing separate opinions on the critical audit matters or on the accounts or disclosures to which they relate. Insperity 2020 Form 10-K F-2 CONSOLIDATED FINANCIAL STATEMENTS Description of the Matter Estimation of the Cost of Incurred Health Insurance Claims As discussed in Note 1 of the consolidated financial statements under “Health Insurance Costs”, the Company provides the majority of its health insurance coverage to its worksite employees through a fully insured health insurance policy with UnitedHealthcare (“United”). While the policy with United is a fully-insured plan, as a result of certain contractual terms, the Company accounts for this plan using a partially self-funded insurance accounting model. Accordingly, the Company records the cost of the United plan, including an estimate of the incurred claims, taxes and administrative fees as benefits expense, which is a component of direct costs. The estimated incurred claims under the Company’s United insurance policy are based upon: (i) the level of claims processed during each quarter; (ii) estimated completion rates based upon recent claim development patterns under the plan; and (iii) the number of participants in the plan, including both active and COBRA enrollees. Auditing management’s estimation of the cost of incurred health insurance claims was subjective and judgmental due to the significant estimation required in determining the medical and pharmacy completion rates. Estimating actual claims incurred is subjective due to the large number of plan participants and the possibility that the number, magnitude, nature, and the timing of processing of current period claims may not be comparable to historical results experienced by the Company. How We Addressed the Matter in Our Audit We obtained an understanding, evaluated the design and tested the operating effectiveness of controls over the estimation process, including, among others, controls over the completeness and accuracy of the data used to estimate the cost of incurred health insurance claims and the review and approval processes that management has in place for the assumptions applied and the calculation of the cost of incurred health insurance claims. With the support of our actuarial specialists, we performed an independent assessment of the estimated cost of incurred health insurance claims. Our audit procedures included, among others, assessing (i) the Company’s health insurance cost estimation methodologies, (ii) significant assumptions used to develop the medical and pharmacy completion rates, which includes the incurred but not reported component, (iii) the accuracy and completeness of the claims processed and the number of plan participants used in the Company’s computation, as well as (iv) the historical accuracy of management’s estimates of the cost of incurred health insurance claims. Our testing of the medical and pharmacy completion rate assumptions included comparing the completion rate assumptions used by management to the completion rates experienced in historical periods and assessing whether contrary evidence exists with respect to the completion rate assumptions utilized by the Company to estimate the cost of incurred health insurance claims. We compared the Company’s estimate to a range developed by our actuarial specialists based on independently selected assumptions and historical data. Insperity 2020 Form 10-K F-3 CONSOLIDATED FINANCIAL STATEMENTS Estimation of the Cost of Incurred Workers’ Compensation Claims and Related Liability Description of the Matter As discussed in Note 1 of the consolidated financial statements under “Workers’ Compensation Costs”, the Company provides workers’ compensation insurance, including ongoing health care and indemnity coverage, to its worksite employees whereby claims are paid over numerous years following the date of injury. Under the Company’s insurance program, the Company has financial responsibility for a significant portion of the workers’ compensation claims. Accordingly, the accrual related to incurred costs includes estimates that take into account the ongoing development of claims and therefore requires a significant level of judgment. The estimated accrued claims are based on (i) the loss development rate which is primarily based upon the nature of worksite employees’ job responsibilities, the location of worksite employees, the historical frequency and severity of workers’ compensation claims, (ii) an estimate of future cost trends, and (iii) discount rates which correspond to the weighted average estimated claim payout period. Auditing management’s estimation of the cost of incurred workers’ compensation claims was subjective due to the significant estimation required in determining the loss development rate and future cost trends. These assumptions have a significant effect on the valuation of the liability. How We Addressed the Matter in Our Audit We obtained an understanding, evaluated the design and tested the operating effectiveness of controls over the estimation process, including, among others, controls over the completeness and accuracy of data used to estimate the cost of incurred workers’ compensation claims and the review and approval processes that management has in place for the assumptions applied and the calculation of the cost of incurred workers’ compensation claims. With the support of our actuarial specialists, we performed an independent assessment of the estimated cost of workers’ compensation claims incurred and the related liability. Our audit procedures included, among others, assessing (i) the Company’s workers’ compensation reserve methodologies, (ii) significant assumptions used to develop the loss development rate, as well as (iii) the historical accuracy of management’s estimates of the cost of incurred workers’ compensation claims. Our audit procedures included testing the completeness and accuracy of the underlying claims and payroll data provided to management's third-party actuaries and reviewing the Company's insurance contracts to assess the Company's self-insured retentions, deductibles, and coverage limits. Furthermore, we involved our actuarial specialists to assist in our evaluation of the methodologies utilized by management's third-party actuaries in developing the reserves recorded by the Company. We compared the Company's reserved amount to a range developed by our actuarial specialists based on historical loss data and independently selected assumptions. We have served as the Company’s auditor since 1991. /s/ Ernst & Young LLP Houston, Texas February 11, 2021 Insperity F-4 2020 Form 10-K CONSOLIDATED FINANCIAL STATEMENTS MANAGEMENT’S REPORT ON INTERNAL CONTROL The Company has assessed the effectiveness of its internal control over financial reporting as of December 31, 2020, based on criteria established in Internal Control – Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (“COSO”) (2013 framework). The Company’s management is responsible for establishing and maintaining adequate internal controls over financial reporting. The effectiveness of the Company’s internal control over financial reporting as of December 31, 2020 has been audited by the Company’s independent registered public accounting firm, as stated in their report that is included herein. 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. 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 the 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 and procedures may deteriorate. The Company’s assessment of the effectiveness of its internal control over financial reporting included testing and evaluating the design and operating effectiveness of its internal controls. In management’s opinion, the Company has maintained effective internal control over financial reporting as of December 31, 2020, based on criteria established in the COSO 2013 framework. /s/ Paul J. Sarvadi Paul J. Sarvadi Chairman of the Board and Chief Executive Officer /s/ Douglas S. Sharp Douglas S. Sharp Senior Vice President of Finance Chief Financial Officer and Treasurer Insperity 2020 Form 10-K F-5 CONSOLIDATED FINANCIAL STATEMENTS REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM To the Stockholders and the Board of Directors of Insperity, Inc. Opinion on Internal Control over Financial Reporting We have audited Insperity, Inc.’s internal control over financial reporting as of December 31, 2020, based on criteria established in Internal Control — Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (2013 framework) (the COSO criteria). In our opinion, Insperity, Inc. (the Company) maintained, in all material respects, effective internal control over financial reporting as of December 31, 2020, based on the COSO criteria. We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States) (PCAOB), the consolidated balance sheets of Insperity, Inc. as of December 31, 2020 and 2019, and the related consolidated statements of operations, comprehensive income, stockholders’ equity and cash flows for each of the three years in the period ended December 31, 2020, and the related notes and our report dated February 11, 2021 expressed an unqualified opinion thereon. 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. 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 included obtaining an understanding of internal control over financial reporting, assessing the risk that a material weakness exists, testing and evaluating the design and operating effectiveness of internal control based on the assessed risk, and 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.

Accounting Policies Description of Business Insperity, Inc. (“Insperity” or “we”, “our”, and “us”) provides an array of human resources (“HR”) and business solutions designed to help improve business performance. Since our formation in 1986, we have evolved from being solely a professional employer organization (“PEO”), an industry we pioneered, to our current position as a comprehensive business performance solutions provider. We were organized as a corporation in 1986 and have provided PEO services since inception. Our most comprehensive HR services offerings are provided through our Workforce Optimization and Workforce Synchronization solutions (together, our “PEO HR Outsourcing solutions”), which encompass a broad range of human resources functions, including payroll and employment administration, employee benefits, workers’ compensation, government compliance, performance management and training and development services, along with our cloud-based human capital management platform, Insperity Premier TM . TM ® In addition to our PEO HR Outsourcing solutions, we offer a comprehensive traditional payroll and human capital management solution, known as Workforce Acceleration. We also offer a number of other business performance solutions, including Comprehensive Traditional Payroll and Human Capital Management, Time and Attendance, Performance Management, Organizational Planning, Recruiting Services, Employment Screening, Retirement Services and Insurance Services, many of which are offered as a cloud-based software solution. These other products or services are offered separately or with our other solutions. We provide our PEO HR Outsourcing solutions by entering into a co-employment relationship with our clients, under which Insperity and its clients each take responsibility for certain portions of the employer-employee relationship. Insperity and its clients designate each party’s responsibilities through its Client Service Agreement (“CSA”), under which Insperity becomes an employer of the employees who work at the client’s location (“WSEE”) for most administrative and regulatory purposes. As a co-employer of our WSEEs, we assume many of the rights and obligations associated with being an employer. We enter into an employment agreement with each WSEE, thereby maintaining a variety of employer rights, including the right to hire or terminate employees, the right to evaluate employee qualifications or performance, and the right to establish employee compensation levels. Typically, Insperity only exercises these rights in consultation with its clients or when necessary to ensure regulatory compliance. The responsibilities associated with our role as employer include the following obligations with regard to our WSEEs: (1) to compensate our WSEEs through wages and salaries; (2) to pay the employer portion of payroll-related taxes; (3) to withhold and remit (where applicable) the employee portion of payroll- related taxes; (4) to provide employee benefit programs; and (5) to provide workers’ compensation insurance coverage. In addition to our assumption of employer status for our WSEEs, our PEO HR Outsourcing solutions also include other human resources functions for our clients to support the effective and efficient use of personnel in their business operations. To provide these functions, we maintain a significant staff of professionals trained in a wide variety of human resources functions, including employee training, employee recruiting, employee performance management, employee compensation and employer liability management. These professionals interact and consult with clients on a daily basis to help identify each client’s service requirements and to ensure that we are providing appropriate and timely personnel management services. Revenue and Direct Cost Recognition On January 1, 2018, we adopted Accounting Standards Update (“ASU”) No. 2014-09, Revenue from Contracts with Customers (Topic 606), using the modified retrospective approach. Under this method, the guidance is applied only to the most current period presented in the financial statements. ASU No. 2014-09 outlines a single comprehensive revenue recognition model for revenue arising from contracts with customers and superseded most of the previous revenue recognition guidance, including industry-specific guidance. Under ASU No. 2014- 09, an entity recognizes revenue for the transfer of promised goods or services to customers in an amount that reflects the consideration for which the entity expects to be entitled in exchange for those goods or services. Our revenue recognition policies remained substantially unchanged as a result of the adoption of ASU No. 2014-09 and we did not have any significant changes in our business processes or systems. Insperity 2020 Form 10-K F-13 Notes to the Consolidated Financial Statements We enter into contracts with our customers for human resources services based on a stated rate and price in the contract. Our contracts generally have a term of 12 months, but are cancellable at any time by either party with 30-days’ notice. Our performance obligations are satisfied as services are rendered each month. The term between invoicing and when our performance obligations are satisfied is not significant. Payment terms are typically due concurrently with the invoicing of our PEO services. We do not have significant financing components or significant payment terms. Our revenue is generally recognized ratably over the payroll period as WSEEs perform their service at the client worksite. Customers are invoiced concurrently with each periodic payroll of its WSEEs. Revenues that have been recognized but not invoiced represent unbilled accounts receivable included in accounts receivable, net on our Consolidated Balance Sheets. Pursuant to the “practical expedients” provided under ASU No 2014-09, we expense sales commissions when incurred because the terms of our contracts are cancellable by either party with a 30-day notice. These costs are recorded in commissions in our Consolidated Statements of Operations. Our revenue for our PEO HR Outsourcing solutions by geographic region and for our other products and services offerings are as follows: (in thousands) Northeast Southeast Central Southwest West Other revenue Total revenue Year Ended December 31, 2019 2018 2020 $ $ 1,189,837 $ 509,846 761,905 935,634 839,347 4,236,569 50,435 4,287,004 $ 1,135,771 $ 499,201 743,514 1,001,845 880,434 4,260,765 54,039 4,314,804 $ 996,541 447,584 637,779 895,243 797,942 3,775,089 53,460 3,828,549 Our PEO HR Outsourcing solutions revenues are primarily derived from our gross billings, which are based on (1) the payroll cost of our WSEEs; and (2) a markup computed as a percentage of the payroll cost. The gross billings are invoiced concurrently with each periodic payroll of our WSEEs. Revenues, which exclude the payroll cost component of gross billings and therefore consist solely of markup, are recognized ratably over the payroll period as WSEEs perform their service at the client worksite. In determining the pricing of the markup component of our gross billings, we take into consideration our estimates of the costs directly associated with our WSEEs, including payroll taxes, benefits and workers’ compensation costs, plus an acceptable gross profit margin. As a result, our operating results are significantly impacted by our ability to accurately estimate, control and manage our direct costs relative to the revenues derived from the markup component of our gross billings. Consistent with our revenue recognition policy, our direct costs do not include the payroll cost of our WSEEs. Our direct costs associated with our revenue generating activities are primarily comprised of all other costs related to our WSEEs, such as the employer portion of payroll- related taxes, employee benefit plan premiums and workers’ compensation insurance costs. Segment Reporting We operate one reportable segment under Accounting Standards Codification (“ASC”) 280, Segment Reporting. Principles of Consolidation The Consolidated Financial Statements include the accounts of Insperity, Inc. and its wholly owned subsidiaries. Intercompany accounts and transactions have been eliminated in consolidation. Insperity 2020 Form 10-K F-14 Notes to the Consolidated Financial Statements Use of Estimates The preparation of financial statements in conformity with United States Generally Accepted Accounting Principles requires management to make estimates and assumptions that affect the amounts reported in the financial statements and accompanying notes. Actual results could differ from those estimates. Concentrations of Credit Risk Financial instruments that could potentially subject us to concentration of credit risk include accounts receivable and marketable securities. Cash, Cash Equivalents and Marketable Securities We invest our excess cash in federal government and municipal-based money market funds and debt instruments of U.S. municipalities. All highly liquid investments with stated maturities of three months or less from date of purchase are classified as cash equivalents. Liquid investments with stated maturities of greater than three months are classified as marketable securities in current assets. We account for marketable securities in accordance with ASC 320, Investments – Debt and Equity Securities. We determine the appropriate classification of all marketable securities as held-to-maturity, available-for-sale or trading at the time of purchase, and re-evaluate such classification as of each balance sheet date. At December 31, 2020 and 2019, all of our investments in marketable securities were classified as available-for-sale, and as a result, were reported at fair value. Unrealized gains and losses are reported as a component of accumulated other comprehensive income (loss) in stockholders’ equity. The amortized cost of debt securities is adjusted for amortization of premiums and accretion of discounts from the date of purchase to maturity. Such amortization is included in interest income as an addition to or deduction from the coupon interest earned on the investments. We use the specific identification method of determining the cost basis in computing realized gains and losses on the sale of our available-for-sale securities. Realized gains and losses are included in other income. Property and Equipment Property and equipment are recorded at cost and are depreciated over the estimated useful lives of the related assets using the straight-line method. Property and equipment, net consisted of the following: (in thousands) Land Buildings and improvements Computer hardware and software Software development costs Furniture, fixtures and other Construction in progress (1) Accumulated depreciation and amortization Total property and equipment, net ____________________________________ (1) Construction in progress is related to our corporate office expansion.

Capitalized software development costs are amortized using the straight-line method over the estimated useful lives of the software, generally three years. We recognized $8.7 million, $7.8 million and $6.0 million in amortization of capitalized computer software costs in 2020, 2019 and 2018, respectively. Unamortized software development costs were $32.6 million and $25.8 million at December 31, 2020 and 2019, respectively. We periodically evaluate our long-lived assets for impairment in accordance with ASC 360-10, Property, Plant, and Equipment. ASC 360-10 requires that an impairment loss be recognized for assets to be disposed of or held-for-use when the carrying amount of an asset is deemed to not be recoverable. If events or circumstances were to indicate that any of our long-lived assets might be impaired, we would assess recoverability based on the estimated undiscounted future cash flows to be generated from the applicable asset. In addition, we may record an impairment loss to the extent that the carrying value of the asset exceeded the fair value of the asset. Fair value is generally determined using an estimate of undiscounted future net cash flows from operating activities or upon disposal of the asset. Leases In February 2016, the Financial Accounting Standards Board (“FASB”) issued ASU No. 2016-02, Leases (Topic 842), which requires lessees to recognize a right-of-use (“ROU”) asset and a lease liability for all leases with terms greater than 12 months and also requires disclosures by lessees and lessors about the amount, timing and uncertainty of cash flows arising from leases. Subsequent to the issuance of Topic 842, the FASB clarified the guidance through several ASUs; hereinafter, the collection of lease guidance is referred to as “ASC 842.” On January 1, 2019, we adopted ASC 842 using the modified retrospective transition method. Results for the reporting period beginning January 1, 2019 are presented under ASC 842, while prior period amounts were not adjusted and continue to be reported in accordance with our historical accounting under ASC 840, Leases. Upon adoption of ASC 842, we increased our total assets and liabilities due to the recording of operating lease ROU assets and operating lease liabilities of approximately $50.8 million and $63.7 million, respectively, as of January 1, 2019. These increases did not have a material impact on our results of operations or cash flows. For all leases that commenced before the effective date of ASC 842, we elected to apply the permitted “practical expedients” to not reassess the following: (1) whether any expired or existing contracts contain leases; (2) the lease classification for any expired or existing leases; and (3) initial direct costs for any existing leases. We determine if an arrangement is a lease at inception of a contract. ROU assets represent our right to use an underlying asset for the lease term and lease liabilities represent our obligation to make lease payments arising from the lease. ROU assets and lease liabilities are recognized at the lease commencement date based on the present value of lease payments over the lease term. As most of our leases do not provide an implicit interest rate, we use our incremental borrowing rate based on the information available at commencement date in determining the present value of lease payments. The lease terms used to calculate the ROU asset and related lease liability include options to extend or terminate the lease when it is reasonably certain that we will exercise that option. Lease expense for operating leases is recognized on a straight-line basis over the lease term as an operating expense. We have lease agreements which require payments for lease and non-lease components and have elected to account for these as a single lease component related to our other operating facilities. Please read Note 11, “Leases,” for additional information. Insperity 2020 Form 10-K F-16 Notes to the Consolidated Financial Statements Goodwill and Other Intangible Assets Our goodwill is not amortized, but is tested for impairment on an annual basis or when there is an indication that there has been a potential decline in the fair value of a reporting unit. Annually, we perform a qualitative analysis to determine if it is more likely than not that the fair value has declined below its carrying value. This analysis considers various qualitative factors. Due to the nature of our business, all of our goodwill is associated with one reporting unit. We perform our annual impairment testing during the fourth quarter. Based on the results of our analysis, no impairment loss was recognized in 2020, 2019 or 2018. At December 31, 2020 and 2019, we had an aggregate carrying amount of goodwill acquired of $21.2 million, which has been reduced by cumulative impairment charges of $8.5 million. Accordingly, our goodwill balance at December 31, 2020 and 2019 was $12.7 million. Health Insurance Costs We provide group health insurance coverage to our WSEEs in our PEO HR Outsourcing solutions through a national network of carriers, including UnitedHealthcare (“United”), UnitedHealthcare of California, Kaiser Permanente, Blue Shield of California, HMSA BlueCross BlueShield of Hawaii and Tufts, all of which provide fully insured policies or service contracts. The policy with United provides approximately 87% of our health insurance coverage. While the policy with United is a fully-insured plan, as a result of certain contractual terms, we have accounted for this plan since its inception using a partially self-funded insurance accounting model. Effective January 1, 2020, under the amended agreement with United, we no longer have financial responsibilities for participant’s annual claim costs that exceed $1 million. Accordingly, we record the cost of the United plan, including an estimate of the incurred claims, taxes and administrative fees (collectively the “Plan Costs”) as benefits expense, which is a component of direct costs, in our Consolidated Statements of Operations. The estimated incurred claims are based upon: (1) the level of claims processed during each quarter; (2) estimated completion rates based upon recent claim development patterns under the plan; and (3) the number of participants in the plan, including both active and COBRA enrollees. Each reporting period, changes in the estimated ultimate costs resulting from claim trends, plan design and migration, participant demographics and other factors are incorporated into the benefits costs, which requires a significant level of judgment. Additionally, since the plan’s inception, under the terms of the contract, United establishes cash funding rates 90 days in advance of the beginning of a reporting quarter. If the Plan Costs for a reporting quarter are greater than the premiums paid and owed to United, a deficit in the plan would be incurred and a liability for the excess costs would be accrued in our Consolidated Balance Sheets. On the other hand, if the Plan Costs for the reporting quarter are less than the premiums paid and owed to United, a surplus in the plan would be incurred and we would record an asset for the excess premiums in our Consolidated Balance Sheets. The terms of the arrangement require us to maintain an accumulated cash surplus in the plan of $9.0 million, which is reported as long-term prepaid insurance. In addition, United requires a deposit equal to approximately one day of claims funding activity, which was $6.5 million as of December 31, 2020, and is reported as a long-term asset. As of December 31, 2020, Plan Costs were more than the net premiums paid and owed to United by $6.0 million. As this amount is less than the agreed-upon $9.0 million surplus maintenance level, the $15.0 million difference is also included in accrued health insurance costs, a current liability, in our Consolidated Balance Sheets. The premiums, including the additional quarterly premiums, owed to United at December 31, 2020, were $11.7 million, which is included in accrued health insurance costs, a current liability in our Consolidated Balance Sheets. Our benefits costs incurred included a reduction of $0.2 million in 2020, an increase of $2.3 million in 2019 and a reduction of $1.3 million in 2018 for changes in estimated run-off related to prior periods. Insperity 2020 Form 10-K F-17 Notes to the Consolidated Financial Statements Workers’ Compensation Costs Our workers’ compensation coverage for our WSEEs in our PEO HR Outsourcing solutions has been provided through an arrangement with the Chubb Group of Insurance Companies or its predecessors (the “Chubb Program”) since 2007. The Chubb Program is fully insured in that Chubb has the responsibility to pay all claims incurred under the policy regardless of whether we satisfy our responsibilities. Under the Chubb Program, for claims incurred on or before September 30, 2019, we have financial responsibility to Chubb for the first $1 million layer of claims per occurrence and, for claims over $1 million, up to a maximum aggregate amount of $6 million per policy year for claims that exceed $1 million. Chubb bears the financial responsibility for all claims in excess of these levels. Effective for claims incurred on or after October 1, 2019, we have financial responsibility to Chubb for the first $1.5 million layer of claims per occurrence and, for claims over $1.5 million, up to a maximum aggregate amount of $6 million per policy year for claims that exceed $1.5 million. Because we bear the financial responsibility for claims up to the levels noted above, such claims, which are the primary component of our workers’ compensation costs, are recorded in the period incurred. Workers’ compensation insurance includes ongoing health care and indemnity coverage whereby claims are paid over numerous years following the date of injury. Accordingly, the accrual of related incurred costs in each reporting period includes estimates, which take into account the ongoing development of claims and therefore requires a significant level of judgment. We utilize a third-party actuary to estimate our loss development rate, which is primarily based upon the nature of WSEEs’ job responsibilities, the location of WSEEs, the historical frequency and severity of workers’ compensation claims, and an estimate of future cost trends. Each reporting period, changes in the actuarial assumptions resulting from changes in actual claims experience and other trends are incorporated into our workers’ compensation claims cost estimates. During the years ended December 31, 2020, 2019 and 2018, we reduced accrued workers’ compensation costs by $42.1 million, $31.7 million and $18.8 million, respectively, for changes in estimated losses related to prior reporting periods. Workers’ compensation cost estimates are discounted to present value at a rate based upon the U.S. Treasury rates that correspond with the weighted average estimated claim payout period (the average discount rate was 0.6% in 2020 and 1.9% in 2019) are accreted over the estimated claim payment period and included as a component of direct costs in our Consolidated Statements of Operations. The following table provides the activity and balances related to incurred but not paid workers’ compensation claims: (in thousands) Beginning balance Accrued claims Present value discount, net of accretion Paid claims Ending balance Current portion of accrued claims Long-term portion of accrued claims Total accrued claims Year Ended December 31, 2020 2019 $ $ $ $ 242,904 $ 42,639 740 (45,522) 240,761 $ 45,522 $ 195,239 240,761 $ 229,639 62,552 (3,643) (45,644) 242,904 49,295 193,609 242,904 The current portion of accrued workers’ compensation costs on the Consolidated Balance Sheets at December 31, 2020 and 2019 includes $2.7 million and $3.6 million, respectively, of workers’ compensation administrative fees. The undiscounted accrued workers’ compensation costs were $257.9 million as of December 31, 2020 and $262.9 million as of December 31, 2019. At the beginning of each policy period, the workers’ compensation insurance carrier establishes monthly funding requirements comprised of premium costs and funds to be set aside for payment of future claims (“claim funds”). The level of claim funds is primarily based upon anticipated WSEE payroll levels and expected workers’ compensation loss rates, as determined by the insurance carrier. Monies funded into the program for incurred claims expected to be paid within one year are recorded as restricted cash, a short-term asset, while the remainder of claim funds are included in deposits, a long-term asset in our Consolidated Balance Sheets. In 2020, we received $28.2 million for the return of excess claim funds related to Insperity 2020 Form 10-K F-18 Notes to the Consolidated Financial Statements the workers’ compensation program, which decreased deposits. As of December 31, 2020, we had restricted cash of $45.5 million and deposits of $186.3 million. Our estimate of incurred claim costs expected to be paid within one year is included in short-term liabilities, while our estimate of incurred claim costs expected to be paid beyond one year is included in noncurrent liabilities on our Consolidated Balance Sheets. Stock-Based Compensation At December 31, 2020, we have one stock-based employee compensation plan under which we may issue awards. We account for this plan under the recognition and measurement principles of ASC 718, Compensation – Stock Compensation, which requires all share-based payments to employees, including grants of employee stock options, to be recognized in the income statement based on their fair values. We generally make annual grants of restricted and unrestricted stock under our stock-based incentive compensation plan to our non- employee directors, officers and other management but changed to restricted stock units for employees in 2020. Restricted stock and restricted stock unit grants to officers and other employees generally vest over a period of three years from the date of grant. Shares of restricted stock and restricted stock units are valued based on the fair value on date of grant and the associated expense, net of estimated forfeitures, is recognized over the requisite service period. Stock grants issued to non-employee directors are 100% vested on the grant date. During 2020, we also granted performance-based restricted stock units to officers and other management, which vest or expire based on the achievement of various performance metrics. Performance-based restricted stock units have a vesting schedule of one year. The fair value of each performance-based restricted stock unit is the market price of our common stock on the date of grant. The compensation expense for such awards is recognized on a straight line basis over the requisite service period. Over the performance period, the number of shares expected to be issued is adjusted upward or downward based on the probability of achievement of the performance target. Our Insperity Long-Term Incentive Program (the “LTIP”) provides for performance based long-term compensation awards in the form of performance units to certain employees based on the achievement of pre-established performance goals. Each performance unit represents the right to receive one common share at a future date based on our performance against certain targets. Performance units have a vesting schedule of three years. Commencing in 2016, a portion of the LTIP grant to employees was considered a market-based performance award that cliff vests at the end of three years assuming continued employment and achievement of market-based performance goals. The fair value of each performance unit is the market price of our common stock on the date of grant. The fair value of each market-based performance unit was determined through use of the Monte Carlo simulation method. The compensation expense for such awards is recognized on a straight line basis over the vesting term. Over the performance period the number of shares expected to be issued is adjusted upward or downward based on the probability of achievement of the performance target. Company-Sponsored 401(k) Retirement Plans Under our 401(k) retirement plan for corporate employees (the “Corporate Plan”), we matched 100% of eligible corporate employees’ contributions, up to 6% of the employees’ eligible compensation in 2020, 2019 and 2018. Matching contributions under the Corporate Plan are immediately vested. During 2020, 2019 and 2018, we made matching contributions on behalf of corporate employees to the Corporate Plan of $12.6 million, $11.4 million and $10.3 million, respectively, and is included in salaries, wages and payroll taxes in our Consolidated Statements of Operations. Under our separate 401(k) retirement plan for WSEEs (the “Worksite Employee Plan”), the match percentage for WSEEs ranges from 0% to 6%, as determined by each client company. Matching contributions under the Worksite Employee Plan are immediately vested. During 2020, 2019 and 2018, we made matching contributions on behalf of WSEEs to the Worksite Employee Plan of $199.2 million, $198.2 million and $165.5 million, respectively. Advertising We expense all advertising costs as incurred. Income Taxes Insperity F-19 2020 Form 10-K Notes to the Consolidated Financial Statements We use the liability method in accounting for income taxes. Under this method, deferred tax assets and liabilities are determined based on differences between financial reporting and income tax carrying amounts of assets and liabilities and are measured using the enacted tax rates and laws in effect when the differences are expected to reverse. On December 22, 2017, the Tax Cuts and Jobs Act (the “2017 Tax Reform Act”) was signed into law. The 2017 Tax Reform Act significantly changed U.S. corporate income tax laws by, among other things, reducing the U.S. corporate income tax rate to 21% beginning in 2018. Please read Note 7, “Income Taxes,” for additional information. Reclassifications Certain immaterial prior year amounts have been reclassified to conform to the 2020 presentation. New Accounting Pronouncements We adopted ASU 2016-13, Financial Instruments - Credit Losses (Topic 326) effective January 1, 2020 with no material impact. Under this standard, we estimate our reserves using information about past events, current conditions and risk characteristics of our client base when assessing risk associated with the collectability of accounts receivables, including unbilled accounts receivables. We require clients to pay invoices for service fees not later than the same day as the applicable payroll date. As such, we generally do not require collateral. As of December 31, 2020, allowance for bad debts was immaterial. 2.

Fair Value Measurements We account for our financial assets in accordance with ASC 820, Fair Value Measurement. This standard defines fair value, establishes a framework for measuring fair value and expands disclosures about fair value measurements. The fair value measurement disclosures are grouped into three levels based on valuation factors: • • • Level 1 - quoted prices in active markets using identical assets Level 2 - significant other observable inputs, such as quoted prices for similar assets or liabilities, quoted prices in markets that are not active, or other observable inputs Level 3 - significant unobservable inputs Insperity 2020 Form 10-K F-20 Notes to the Consolidated Financial Statements Fair Value of Instruments Measured and Recognized at Fair Value The following tables summarize the levels of fair value measurements of our financial assets: (in thousands) Money market funds U.S. Treasury bills Municipal bonds Total Total December 31, 2020 Level 1 Level 2 Total December 31, 2019 Level 1 Level 2 $ $ 551,213 $ 10,531 23,998 585,742 $ 551,213 $ 10,531 — 561,744 $ — — 23,998 23,998 $ $ 363,075 $ 34,728 — 397,803 $ 363,075 $ 34,728 — 397,803 $ — — — — The municipal bond securities valued as Level 2 investments are primarily pre-refunded municipal bonds that are secured by escrow funds containing U.S. Government securities. Our valuation techniques used to measure fair value for these securities during the period consisted primarily of third-party pricing services that utilized actual market data such as trades of comparable bond issues, broker/dealer quotations for the same or similar investments in active markets and other observable inputs. The following is a summary of our available-for-sale marketable securities: (in thousands) December 31, 2020 U.S. Treasury bills Municipal bonds December 31, 2019 U.S. Treasury bills Amortized Cost Gross Unrealized Gains Gross Unrealized Losses Estimated Fair Value $ $ 10,530 $ 23,994 1 $ 8 — $ (4) 10,531 23,998 34,716 $ 13 $ (1) $ 34,728 As of December 31, 2020, the contractual maturities of all marketable securities in our portfolio were less than one year. Fair Value of Other Financial Instruments The carrying amounts of cash, cash equivalents, restricted cash, accounts receivable and accounts payable approximate their fair values due to the short-term maturities of these instruments. At December 31, 2020, the carrying value of our borrowings under our revolving credit facility approximates fair value and was classified as Level 2 in the fair value hierarchy. Please read Note 6, "Long-Term Debt," for additional information. 4. Accounts Receivable Accounts receivable, net consisted of the following: (in thousands) Trade, net Unbilled Other Accounts receivable, net December 31, 2020 6,559 380,819 5,368 392,746 $ $ 2019 12,731 448,088 4,960 465,779 $ $ Our accounts receivable is primarily composed of trade receivables and unbilled receivables. Our trade receivables, which represent outstanding gross billings to clients, are reported net of allowance for doubtful accounts of $1.0 million and $0.9 million as of December 31, 2020 and 2019, respectively. We establish an allowance for doubtful accounts based on management’s assessment of the collectability of specific accounts and by making a general provision for other potentially uncollectible amounts. Insperity 2020 Form 10-K F-21 Notes to the Consolidated Financial Statements We make an accrual at the end of each accounting period for our obligations associated with the earned but unpaid wages of our WSEEs and for the accrued gross billings associated with such wages. These accruals are included in accrued WSEE payroll cost and unbilled accounts receivable; however, these amounts are presented net in the Consolidated Statements of Operations. We generally require clients to pay invoices for service fees no later than the same day as the applicable payroll date. As such, we generally do not require collateral. Client prepayments directly attributable to accrued worksite employee payroll costs and unbilled revenues have been netted as we have the legal right of offset for these amounts. Unbilled accounts receivable consisted of the following: (in thousands) Accrued worksite employee payroll cost Unbilled revenues Client prepayments Unbilled accounts receivable 5.

Please read Note 1, “Accounting Policies,” for a discussion of our accounting policies for health insurance costs and workers’ compensation costs. 6. Long-Term Debt We have a $500 million revolving credit facility (the “Facility”) which is available for working capital and general corporate purposes, including acquisitions, stock repurchases and issuances of letters of credit. Borrowings may be increased to $550 million based on the terms and subject to the conditions set forth in the agreement relating to the Facility (the “Credit Agreement”). Our obligations under the Facility are secured by 65% of the stock of our captive insurance subsidiary and are guaranteed by all of our domestic subsidiaries. In addition, as of December 31, 2020, we had an outstanding $1.0 million letter of credit issued under the Facility. As of December 31, 2020, our outstanding balance on the Facility was $369.4 million and is due when the Facility matures on September 13, 2024. Borrowings under the Facility bear interest at an annual rate equal to an alternate base rate or LIBOR, at our option, plus an applicable margin. Depending on our leverage ratio, the applicable margin varies (1) in the case of LIBOR loans, from 1.50% to 2.25% and (2) in the case of alternate base rate loans, from 0.00% to 0.50%. The alternate base rate is the highest of (1) the prime rate most recently published in The Wall Street Journal, (2) the federal funds rate plus 0.50% and (3) the 30-day LIBOR rate plus 2.00%. We also pay an unused commitment fee on the average daily unused portion of the Facility at a rate of 0.25%. The average interest rate during 2020 was 2.4%. Interest expense and unused commitment fees are recorded in other income (expense). Upon the discontinuation of LIBOR, the Facility provides that we and the agent will negotiate in good faith to amend the agreement to address such discontinuation and to place the parties in substantially the same economic position. The Facility contains both affirmative and negative covenants that we believe are customary for arrangements of this nature. Covenants include, but are not limited to, limitations on our ability to incur additional indebtedness, sell material assets, retire, redeem or otherwise reacquire our capital stock, acquire the capital stock or assets of another business, make investments and pay dividends. In addition, the Credit Agreement requires us to comply with financial covenants limiting our Insperity 2020 Form 10-K F-22 Notes to the Consolidated Financial Statements total funded debt, minimum interest coverage ratio and maximum leverage ratio. We were in compliance with all financial covenants under the Credit Agreement at December 31, 2020. 7. Income Taxes Deferred taxes reflect the net tax effects of temporary differences between the carrying amounts of assets and liabilities used for financial reporting purposes and the amounts used for income tax purposes. Significant components of the net deferred tax assets as reflected on the Consolidated Balance Sheets are as follows: (in thousands) Deferred tax liabilities Prepaid assets Depreciation Software development costs Tenant improvements Right-of-use leased assets Intangibles Total deferred tax liabilities Deferred tax assets Accrued incentive compensation Net operating loss carryforward Workers’ compensation accruals Accrued rent Stock-based compensation Operating lease liabilities Minority investment impairment Cares act deferral Other Total deferred tax assets Valuation allowance Total net deferred tax assets Net deferred tax assets December 31, 2020 2019 $ (4,207) $ (4,941) (8,230) (3,702) (17,322) (1,444) (39,846) 5,092 558 6,310 1,553 11,383 21,024 676 3,235 294 50,125 (676) 49,449 (4,252) (4,564) (6,475) (3,209) (15,949) (955) (35,404) 5,946 632 5,404 1,223 6,712 19,158 673 — 287 40,035 (675) 39,360 $ 9,603 $ 3,956 Insperity 2020 Form 10-K F-23 Notes to the Consolidated Financial Statements The components of income tax expense are as follows: (in thousands) Current income tax expense Federal State Total current income tax expense Deferred income tax (benefit) expense Federal State Total deferred income tax (benefit) expense Total income tax expense Year Ended December 31, 2019 2018 2020 $ $ 45,558 $ 11,122 56,680 27,385 $ 6,299 33,684 40,347 11,133 51,480 (4,678) (969) (5,647) 51,033 $ 4,016 844 4,860 38,544 $ (3,398) (1,135) (4,533) 46,947 In 2016, we prospectively adopted ASU No. 2016-09, Compensation-Stock Compensation (Topic 718): Improvements to Employee Share- Based Payment Accounting. We recognized an income tax benefit of $2.1 million in 2020, $14.6 million in 2019 and $3.9 million in 2018 related to excess tax benefits from the vesting of equity compensation.

We recognize interest and penalties related to uncertain tax positions in income tax expense. As of December 31, 2020, 2019 and 2018, we made no provisions for interest or penalties related to uncertain tax positions. The tax years 2017 through 2019 remain open to examination by the Internal Revenue Service of the United States. The tax years 2016 through 2019 remain open to examination by various state tax authorities. Insperity 2020 Form 10-K F-24 Notes to the Consolidated Financial Statements 8. Stockholders’ Equity Repurchase Program Our Board of Directors (the “Board”) has authorized a program to repurchase shares of our outstanding common stock (“Repurchase Program”). The purchases are to be made from time to time in the open market or directly from stockholders at prevailing market prices based on market conditions or other factors. We repurchased 1,285,696 shares under the Repurchase Program during 2020. In addition, 151,332 shares were withheld during 2020 to satisfy minimum tax withholding obligations for the vesting of long-term incentive, restricted stock awards and restricted stock units, which are not subject to the Repurchase Program. In 2020, the Board authorized an increase of 2 million shares that may be repurchased under the Repurchase Program. During 2019, we repurchased 1,897,322 shares under the Repurchase Program and 227,208 shares were withheld to satisfy minimum tax withholding obligations for the vesting of long-term incentive and restricted stock awards. At December 31, 2020, we were authorized to repurchase an additional 1,128,137 shares under the Repurchase Program. Shares repurchased under the Repurchase Program are recorded in treasury. Dividends The Board declared quarterly dividends as follows: (amounts per share) First quarter Second quarter Third quarter Fourth quarter $ 2020 0.40 $ 0.40 0.40 0.40 2019 0.30 0.30 0.30 0.30 During 2020 and 2019, we paid a total of $61.9 million and $48.6 million, respectively, in dividends. Preferred Stock At December 31, 2020, 20 million shares of preferred stock were authorized. Rights Plan On May 21, 2020, the Board declared a dividend of one right (“Right”) for each outstanding share of common stock to common stockholders of record at the close of business on June 1, 2020 (the “Rights Plan”). Each Right, if and when it becomes exercisable, entitles the registered holder to purchase from us one unit consisting of one one-hundredth of a share of Series A Junior Participating Preferred Stock, par value $0.01 per share. Initially, the Rights are attached to all outstanding shares of our common stock. The Rights are not currently exercisable and the Rights Plan will expire at the close of business on May 20, 2021, unless the Rights are earlier redeemed or exchanged by us. 9. Incentive Plans The Insperity, Inc. 2001 Incentive Plan, as amended, and the 2012 Incentive Plan, as amended, (collectively, the “Incentive Plans”) provide for options and other stock-based awards that have been and may be granted to eligible employees and non-employee directors of Insperity or its subsidiaries. The 2012 Incentive Plan is currently the only plan under which new stock-based awards may be granted.The 2001 Incentive Plan only has outstanding nonqualified stock options. The 2012 Incentive Plan permits stock options, including nonqualified stock options and options intended to qualify as “incentive stock options” within the meaning of Section 422 of the Internal Revenue Code, stock awards, phantom stock awards, stock appreciation rights, performance units, and other stock-based awards and cash awards, all of which may or may not be subject to the achievement of one or more performance objectives. The purpose of the Incentive Plan generally is to retain and attract persons of training, experience and ability to serve as employees of Insperity and its subsidiaries and to serve as non- employee directors of Insperity, to encourage the sense of proprietorship of such persons and to stimulate the active interest of such persons in the development and financial success of Insperity and its subsidiaries. The Incentive Plans are administered by the Compensation Committee of the Board (the “Committee”). The Committee has the power to determine which eligible employees will receive awards, the timing and manner of the grant of such awards, the exercise price of stock options (which may not be less than market value on the date of grant), the number of shares and all of the terms of the awards. The Board may at any time amend or terminate the Incentive Plans. However, no Insperity 2020 Form 10-K F-25 Notes to the Consolidated Financial Statements amendment that would impair the rights of any participant, with respect to outstanding grants, can be made without the participant’s prior consent. Stockholder approval of amendments to the Incentive Plans is necessary only when required by applicable law or stock exchange rules. Assuming all outstanding awards are paid at max, at December 31, 2020, 1,417,062 shares of common stock were available for future grants under the 2012 Incentive Plan. We also maintain the Insperity, Inc. Long-Term Incentive Plan (“LTIP”) under the 2012 Incentive Plan. The LTIP provides for performance- based long-term compensation awards in the form of performance units to certain employees based on the achievement of pre-established performance goals. We granted performance units under the LTIP to our named executive officers and certain other officers in 2018, 2019 and 2020. Beginning with stock-based awards granted in 2020, employees who attain a minimum age of 62 and have provided 15 years or more of continuous service may continue to vest in awards following a qualifying retirement as defined under the 2012 Incentive Plan award agreement, as though he or she were still an employee, provided the grant date of the award is six months or more before the employee’s last day of employment. For a termination following a qualifying retirement, time-vested awards will continue to vest in the normal course. For a termination following a qualifying retirement, performance-based awards with completed or in-process performance periods are adjusted for achievement of the performance criteria, prorated through the date of termination and paid in the normal course, while performance- based awards for performance periods that have not started are forfeited. Stock-based compensation expense related to time-vested and performance-based awards is accelerated over the requisite service period for employees who meet the requirements for continued vesting. Stock-based compensation expense and other disclosures for stock-based awards follows: (in thousands) Year Ended December 31, 2019 2018 2020 Stock-based compensation expense recognized Income tax benefit realized from stock-based compensation expense $ 60,145 $ 16,217 23,993 $ 4,876 20,425 5,249 Time-Based Restricted Stock Awards and Time-Based Restricted Stock Units Time-based restricted stock awards (“RSAs”) and time-based restricted stock units (“RSUs”), under equity plan accounting, are generally measured at fair value on the date of grant based on the number of shares granted, estimated forfeitures and the quoted price of the common stock. Such value is recognized as compensation expense over the corresponding vesting period, generally three years to five years for awards currently outstanding. However, for some RSUs currently outstanding, compensation expense is accelerated over the shortened requisite service period for employees who meet the requirements for continued vesting. Following is a summary of time-based RSAs and time-based RSUs award activity for 2020: Non-vested - December 31, 2019 Granted Vested Canceled Non-vested - December 31, 2020 Additional disclosures for time-based RSAs and time-based RSUs: Total Awards (in thousands) Weighted Average Grant Date Fair Value 443 $ 468 (262) (13) 636 $ 86.10 66.32 70.65 79.89 78.04 Year Ended December 31, 2019 2018 2020 Weighted average grant date fair value of awards granted Fair value of awards vested during the year (in millions) $ 66.32 $ 18.1 124.04 $ 39.7 65.98 1.2 Insperity 2020 Form 10-K F-26 Notes to the Consolidated Financial Statements As of December 31, 2020, unrecognized compensation expense associated with the unvested RSAs and RSUs outstanding was $26.1 million and is expected to be recognized over a weighted average period of 20 months. Long-Term Incentive Program Awards Each performance unit represents the right to receive common shares at a future date based on our performance against specified targets. The ultimate number of shares issued and the related compensation cost recognized is based on a comparison of the final performance metrics to the specified targets, which can range from 0% to 200% of the targeted amounts. A performance unit may be comprised of either a performance based award or a market-based award. For performance-based awards, performance units have a vesting schedule of three years and compensation expense is recognized based on the number of common shares expected to be issued and the market price per common share on the date of grant. Over the performance period, the number of shares expected to be issued is adjusted upward or downward based upon the probability of achievement of the performance targets. For market-based awards, performance units vest at the end of a three-year period assuming continued employment and achievement of market-based performance goals. The fair value of market- based performance awards was determined through the use of the Monte Carlo simulation method. The compensation expense for the LTIP awards is recognized on a straight-line basis over the vesting terms. The following is a summary of LTIP award activity, at 100% of targeted amount, for 2020: Unvested at December 31, 2019 Granted Vested Unvested at December 31, 2020 Number of Performance Units (in thousands) Weighted Average Grant Date Fair Value 272 113 (115) 270 $ $ 79.95 70.05 48.06 89.40 The determination of achievement results and corresponding vesting of the 2017 LTIP awards occurred in February 2020 resulting in the recipients receiving approximately 238,000 shares of common stock with a fair value $17.3 million. As of December 31, 2020, we estimate that approximately 167,000, 21,000 and 89,000 shares will vest with $0.3 million, $1.0 million and $2.4 million in unamortized compensation expense related to the 2018, 2019 and 2020 LTIP grants, respectively. Performance-Based Restricted Stock Units During 2020, we granted performance-based RSUs (“pRSU”) under the 2012 Incentive Plan to our named executive officers and certain other management. The pRSUs are performance-based short-term compensation awards in the form of performance units to certain employees based on the achievement of pre-established performance goals. Each pRSU represents the right to receive common shares at a future date based on our performance against specified targets. The ultimate number of shares issued and the related compensation cost recognized is based on a comparison of the final performance metrics to the specified targets, which can range from 0% to 300% of the targeted amounts. The pRSUs have a vesting schedule of less than one year and compensation expense is recognized based on the number of common shares expected to be issued and the market price per common share on the date of grant. For pRSUs currently outstanding, compensation expense is accelerated over the requisite service period for employees who meet the requirements for continued vesting. Over the performance period, the number of shares expected to be issued is adjusted upward or downward based upon the probability of achievement of the performance targets. During 2020, we granted approximately 221,000 pRSUs (at target) with a weighted average grant date fair value of $64.85 and canceled approximately 2,000 pRSUs (at target) with a weighted average grant date fair value of $65.19. At December 31, 2020, we had approximately 219,000 unvested pRSUs (at target) with a weighted average grant date fair value of $64.85. Insperity 2020 Form 10-K F-27 Notes to the Consolidated Financial Statements As of December 31, 2020, we estimate that approximately 379,000 pRSUs will vest with $1.5 million in unamortized compensation expense related to the 2020 pRSU grants. Employee Stock Purchase Plan Our employee stock purchase plan (the “ESPP”) enables employees to purchase shares of Insperity stock at a 5% discount. The ESPP is a non-compensatory plan under generally accepted accounting principles of stock-based compensation. As a result, no compensation expense is recognized in conjunction with this plan. Approximately 57,000, 29,000 and 30,000 shares were issued from treasury under the ESPP during fiscal years 2020, 2019 and 2018, respectively. 10. Net Income Per Share We utilize the two-class method to compute net income per share. The two-class method allocates a portion of net income to participating securities, which includes unvested awards of share-based payments with non-forfeitable rights to receive dividends. Net income allocated to unvested share-based payments is excluded from net income allocated to common shares. Any undistributed losses resulting from dividends exceeding net income are not allocated to participating securities. Basic net income per share is computed by dividing net income allocated to common shares by the weighted average number of common shares outstanding during the period. Diluted net income per share is computed by dividing net income allocated to common shares by the weighted average number of common shares outstanding during the period, plus the dilutive effect of outstanding stock options. The following table summarizes the net income allocated to common shares and the basic and diluted shares used in the net income per share computations: (in thousands) Year Ended December 31, 2019 2018 2020 Net income Less distributed and undistributed earnings allocated to participating securities Net income allocated to common shares $ $ 138,237 $ (782) 137,455 $ 151,099 $ (1,759) 149,340 $ 135,413 (1,875) 133,538 Weighted average common shares outstanding Incremental shares from assumed time-vested and performance-based RSU awards and conversions of common stock options Adjusted weighted average common shares outstanding 38,503 40,186 41,217 317 38,820 166 40,352 289 41,506 Potentially dilutive securities not included in weighted average share calculation due to anti- dilutive effect 133 — — 11. Leases In 2019, we adopted ASU No. 2016-02, Leases (Topic 842). We have operating leases for office space, other operating facilities, vehicles and office equipment. Our fixed operating lease costs for 2020, 2019 and 2018 were $17.3 million, $15.9 million and $15.4 million, respectively, and are included in general and administrative expenses on our Consolidated Statements of Operations. During 2020, cash paid for amounts included in the measurement of operating lease liabilities was $19.1 million.

Commitments and Contingencies We enter into fixed purchase and service obligations in the ordinary course of business. These arrangements primarily consist of advertising commitments and service contracts. At December 31, 2020, future purchase and service obligations greater than $100,000 and one year were as follows (in thousands): 2021 2022 2023 2024 2025 Thereafter Total obligations $ $ (1) 24,580 12,792 3,633 1,283 665 329 43,282 ____________________________________ (1) Includes $3.4 million related to the construction of a new facility on our corporate campus. Insperity 2020 Form 10-K F-29 Notes to the Consolidated Financial Statements Worksite Employee 401(k) Retirement Plan Class Action Litigation In December 2015, a class action lawsuit was filed against us and a third-party who served as the discretionary trustee (the “Co-Defendant”) of the Insperity 401(k) retirement plan that is available to eligible worksite employees (the “Plan”) in the United States District Court for the Northern District of Georgia, Atlanta Division, on behalf of Plan participants. The suit generally alleges the third-party discretionary trustee of the Plan and Insperity breached their fiduciary duties to plan participants by selecting an Insperity subsidiary to serve as the recordkeeper for the Plan, by causing participants in the Plan to pay excessive recordkeeping fees to the Insperity subsidiary, by failing to monitor other fiduciaries, and by making imprudent investment choices. The court certified a class defined as “all participants and beneficiaries of the Insperity 401(k) Plan from December 22, 2009 through September 30, 2017.” The court dismissed the breach of fiduciary duty claims relating to the selection of an Insperity subsidiary to serve as the recordkeeper of the Plan. On March 28, 2019, the court partially granted Insperity’s motion for summary judgment, resulting in the dismissal of the claims concerning allegations of excessive recordkeeping fees. The court denied the plaintiffs’ request for a jury trial and set a bench trial, which was held from March 2, 2020 to March 13, 2020. At trial, the plaintiffs alleged damages up to approximately $146.0 million against all defendants. All parties filed proposed findings of fact and conclusions of law on June 15, 2020. On September 18, 2020, the plaintiffs and Co-Defendant informed the court that they reached an agreement in principle to settle the entire case, including a full and final release of all claims against Insperity. Insperity did not participate in the settlement discussions and will make no financial contribution to the settlement. In connection with the settlement, the plaintiffs and Co-Defendant filed a motion to extend the class period to March 31, 2019, which the court granted. The court has also granted preliminary approval of the settlement and has set the final approval hearing on March 5, 2021. As a result of the uncertainty regarding the outcome of this matter and the subsequent settlement agreement that, if approved by the court, will end the case with no financial contribution from Insperity, no provision has been made in the accompanying Consolidated Financial Statements. Securities Class Action Lawsuit In July 2020, a federal securities class action was filed against us and certain of our officers in the United States District Court for the Southern District of New York. The name of the case is Building Trades Pension Fund of Western Pennsylvania v. Insperity, Inc., et al., Case No. 1:20-cv-05635-NRB. On October 23, 2020, the court issued an order appointing Oakland County Employees’ Retirement System and Oakland County Voluntary Employees’ Beneficiary Association Trust as lead plaintiff. On December 22, 2020, the lead plaintiff filed its consolidated complaint alleging that we made materially false and misleading statements regarding our business and operations in violation of the federal securities laws and seeking unspecified damages, attorneys’ fees, costs, equitable/injunctive relief, and such other relief that may be deemed proper. We believe the allegations in the action are without merit, and we intend to vigorously defend this litigation. As a result of uncertainty regarding the outcome of this matter, no provision has been made in the accompanying Consolidated Financial Statements. Other Litigation We are a defendant in various other lawsuits and claims arising in the normal course of business. Management believes it has valid defenses in these cases and is defending them vigorously. While the results of litigation cannot be predicted with certainty, management believes the final outcome of such litigation will not have a material adverse effect on our financial position or results of operations.
