all other matters for which TriNet does not assume responsibility under the client service agreement, such as intellectual property ownership and protection and liability for products produced and services provided by the client company to its own clients.
As a result of our co-employment relationships for PEO services, we are liable for payment of salary, wages and certain other compensation to the WSEs as reported and paid to us by theour client, and we are responsible for providing specified employee benefits to such persons to the extent provided in each client service agreement and under federal and state law. In most instances, clients are required to remit payment prior to the applicable payroll date by wire transfer or ACH.

WeFor our PEO services, we also assume responsibility for payment and liability for the withholding and remittance of federal and state income and employment taxes with respect to salaries, wages and certain other compensation paid to WSEs, although we reserve the right to seek recourse against our clients for any liabilities arising out of their conduct. We perform these functions as the statutory employer for federal employment tax purposes, since our clients transfer legal control over these payroll functions to us. The laws that govern the payment of salaries, wages and related payroll taxes for our WSEs are complex and the various federal, state and local laws that govern such payments can vary significantly. Based on applicable law in any jurisdiction, we or our client may be held ultimately liable for those obligations if we fail to remit taxes. 
Our HRIS services do not involve co-employment, and this reduces the responsibility and liability that we assume when providing these services. For example, while our software may facilitate payroll processing for HRIS clients, TriNet is not the employer of record and acts only in a software provider role. HRIS clients generally remain responsible for, among other things, payroll funding, workers’ compensation insurance, obtaining and administering group health, welfare and retirement benefits, administering unemployment claims, and in some cases payroll tax reporting. The higher level of responsibility that our PEOs assume, and risks that our PEOs manage, for our PEO clients is a key differentiator between our PEO and HRIS services.
Market Trends and Developments Affecting Our Business in 20212023
Despite the continuation of the COVID-19 pandemic, the
The U.S. economy saw substantial recovery in 2021 duegrew modestly during 2023 with unemployment remaining low while inflation began to abate over the easing of COVID-19 restrictions, consumer demand and continued federal and state legislative efforts to help businesses and employees.year. We observed the following PEO industry trends in 2021:2023:
SMB Economic RecoveryPerformance. The U.S. economy saw substantial recovery from the pandemic driven economic downturnOver any year, SMBs generally experience staffing changes, either resulting in 2020, howevera net increase or decrease in staffing. In 2023 the extent of the recovery for SMBsnet staffing increases differed significantly based on their industry and geographic region. For example, SMBsOur clients experienced significant staffing reductions in the financial services, technology sector, and reductions in the professional services sector, while staffing levels in other industries generally experienced shallower headcount declinesremained stable. Overall in 2020 and have recovered headcount more quickly in 2020 and 2021 as2023, our SMB clients still increased their workforces were better able to transition to remote work. Meanwhile, SMBs instaffing, however the retail, leisure and hospitality industries generally experienced significant headcount freezes, furloughs and terminations in 2020, and these headcount declines have been slow to recover in 2020 and 2021. Similarly, SMBs in geographic regions that saw significant increases in COVID-19 cases in 2021 from the Delta and Omicron variants have generally experienced more significant economic headwinds.increase was significantly lower overall than historic trends.
Continued Insurance Cost Variability and Volatility. The volumeIn 2023, we experienced increased health benefits utilization and inflation in health costs. We believe this occurred in part due to market-wide pharmaceutical price increases, as well as the impact of medical claims, including COVID-19 testing, treatmentrising wages and vaccinationother costs which led to increased costs associated with contract renewals between health insurers and health care providers. These higher costs over the year were and continue to be reflected in 2021, however medical claim volume remained below pre-pandemic levels. Access to medical services and systems remained constrained in 2021, particularly in regions that saw increases in COVID-19 hospitalizations that reduced preventative and elective procedures.2023 health claims.
Tax Credit Backlogs. Many of the key economic assistance programs that SMBs relied on during the COVID-19 pandemic have now expired, including the Employee Retention Tax Credit (ERTC). Although these programs have expired, processing backlogs and a temporary halt in September 2023 in processing new ERTC claims at the IRS have resulted in many SMBs, including some of our clients, continuing to wait to receive their tax credits. In many cases, SMBs still participated in these programs retroactively via payroll tax filing amendments. The regulatory uncertainty surrounding the end date for the filing of ERTC claims and its impact on our PEO clients in particular exacerbates this trend and its impact.
Interest Rates. The same rise in interest rates that is contributing to lower overall hiring among our SMB clients also contributed to higher interest income we receive on our cash deposits and higher interest expense on our debt. While the Federal Reserve's last increase to the Federal Funds Rate was in the middle of 2023, the impacts of the higher rates continue to contribute to our earnings, as well as contributed to higher interest costs as we issued debt and borrowed on our credit line in August and September of 2023.
Privacy Laws and Regulations. NumerousWe have seen increased focus at every level of government inside and outside of the United States on regulating the collection, storage, use, retention, security, disclosure, transfer and other processing of confidential, sensitive and personal information, as well as the growing use of artificial intelligence. As the patchwork of laws becomes increasingly complex, we expect the effort and regulations were created or modified in 2021 that had an impact on our businesscost of complying with all of the requirements to also increase and the businesseslikelihood of compliance failures to rise.
PEO Benefit Plan Legislation. We saw an increase in state efforts to regulate PEO health plans. For example, new legislation and proposed rules in New Mexico seek to prevent WSEs of small group employers from participating in PEO-sponsored large group market health plans, with the exception for plans the PEOs register as MEWAs under state law. State regulations on PEO health plans can limit our options for providing TriNet sponsored benefits to our PEO clients or eliminate those benefits entirely, so we devote substantial time and SMBsresources to monitor and respond to these developments. We expect to continue to see similar legislative and regulatory efforts across the country. For example, the PPPFA and ARPA, were passed in 2021 to augment and extend 2020 programs intended to assist SMB’s and their employees to recover from the impacts of COVID-19. The paid leave and corresponding employer tax credit under the FFCRA was modified and extended through the third quarter of 2021, and the employee retention credit program under the CARES Act was also extended and modified before being retroactively terminated effective at end of the third quarter of 2021. Additional provisions of the CCPA became effective in 2021, and the DOL issued regulatory guidance regarding cybersecurity measures applicable to retirement plans. Federal and state views on employees and independent contractors remained in flux during 2021 as we saw a California state court find that Proposition 22, which was a modification of an earlier law that reclassified certain independent contractors as employees, was unconstitutional and unenforceable. The National Labor Relations Board (NLRB) also announced plans to create a new rule for determining whether two business are joint employers or co-employers and is expected to announce this new rule in 2022. We do not believe we are a joint employer, but changes in regulations determining joint employer status could lead to increased legal claims against us or our clients, increase our compliance costs, or require changes to how we operate our business and the services we provide to our clients and WSEs.

The first services on this next generation cloud-based platform went live in 2023 and as we createdcontinue to bring more innovation to our entire customer base we expect that our investment and prioritization in 2020 to support several important funding and payroll tax incentive programs for SMBs created under the FFCRA, CARES Act and PPFA, including PPP, mandatory employee leave requirements, payroll tax deferral and tax credit programs and other employment- and employment tax-related incentives. Changes to these programs in 2021, including guidance from the state and federal agencies managing these programs, requiredthis area will increase. We believe this will enable us to create new services, or redesignservice SMBs throughout a larger portion of their lifecycle. Additionally, our existing services,TriNet Clarus R+D cloud-based software platform allows us to support these programs forserve our existing SMB clients and to serve SMBs that are not currently a client of our PEO or HRIS services with tax credit support services. The services we expectprovide through our HRIS and TriNet Clarus R+D software platforms create a potential pipeline of SMB clients that may benefit from, and transition to, continueTriNet’s higher-touch PEO services at future points in their lifecycle.
In 2023 TriNet moved all of our applications, computing and storage to make changesthe cloud in a multi-cloud strategy which enabled the shutdown of all on-premise data centers.

Our tax credit services face competition from large CPA firms, such as PwC, Ernst &Young, Moss Adams, and KPMG and smaller software companies and CPA firms, such as alliantgroup, Ardius, Cherry Bekaert and Eide Bailly.
We believe that a key reason why our PEO services are attractive to many SMBs in partis because of our ability to provide access to a broad range of TriNet-sponsored workers compensation, health insurance and other benefits programs on a cost-effective basis. We compete with insurance brokers and other providers of insurance and benefits coverage, and our PEO offerings must be priced competitively with those provided by these competitors in order for us to attract and retain our clients.
We believe that we also compete based upon the breadthOur PEO clients are typically looking for high-touch HR compliance and depthservices support, TriNet sponsored employee benefits, TriNet responsibility for processing payroll and payroll taxes, and access to EPLI claims support and other substantial HR services.

The Laws and Regulations that Affect Our Business
Our business operates in a complex legal and regulatory environment due to a myriad of federal, state and local laws and regulations that impact our business. Below is a summary of what we believe are the most important legal and regulatory issues forspecific to our business. For additional information on the impact of these and other laws and regulations on our business and results of operations, refer to Part I, Item 1A. Risk Factors, of this Form 10-K, under the heading - "Legal and Compliance Risks".
Employer Status under ERISA and State Laws
WeAs part of our PEO services, we sponsor our employee benefit plan offerings as the employer of our WSEs under the Internal Revenue Code of 1986, as amended (the Code)"Code"), ERISA and applicable state law. The term “employer” has different definitions for different purposes under the Code and ERISA, and for most purposes are interpreted under complex multi-factor tests under common law. As an employer of WSEs, we must manage our benefit plans in accordance with ERISA requirements, which can impact how we fulfill plan obligations, how we price services, the features of our benefit plans, and how we administer and operate our plans. We believe we manage our benefit plans in accordance with ERISA requirements and that we are an “employer”employer of our WSEs in the U.S. under the Code, and the employer of our WSEs in the U.S. for the purposes of ERISA, as well as qualifying as an employer under various state laws, but this status could be subject to challenge by various regulators.

Health Insurance and Health Care Reform
Our sponsored employee health and welfare offerings are an important component of the services that we provide. The future of health care reform continues to evolve in the U.S. For example, the passage of the ACA in 2010 implemented sweeping health care reforms with staggered effective dates from 2010 through 2022, and many provisions in the ACA are still subject to the issuance of additional guidance from the DOL, the IRS, the U.S. Department of Health and Human Services and various U.S. states. Passage of the TCJA in 2017 eliminated the individual mandate tax penalty under the ACA beginning in 2019, while retaining employer ACA mandate obligations. States have developed, and will continue to develop, varying approaches to state-based health exchanges and mandates. Further significant changes to health care statutes, regulations and policy at the federal, state and local levels could occur in 20222024 and beyond, including the potential further modification or amendment of the ACA, and we may need to adapt the manner in which we conduct our business as a result of any such changes. For additional information on the ACAhealth care reform and its impact on our business and results of operations, refer to Part I, Item 1A. Risk Factors, of this Form 10-K, under the heading - "Changing laws and regulations governing health insurance and other traditional employee benefits at the federal, state and local level could negatively affect our business".
Data Privacy and Security Regulations
We collect, store, use, retain, disclose, transfer and otherwise process a significant amount of confidential, sensitive and personal information from and about our actual and potential clients, WSEs, HRIS Users and corporate employees,colleagues, and we are subject to a variety of federal, state and foreigninternational laws, rules, and regulations in connection with such activities. As a sponsor of employee benefit plans, we also have access to certain protected health information (PHI) of our WSEs and corporate employees.colleagues. Management of PHI is subject to several regulations at the federal level, including HIPAA and the HITECH Act. HIPAA contains restrictions and health data privacy, security and breach notification requirements with respect to the use and disclosure of PHI. Further, there are penalties and fines for HIPAA violations. Because TriNet sponsored health plans are covered entities under HIPAA, we are required to comply with HIPAA's portability, privacy, and security requirements. We are also subject, among other applicable federal laws, rules and regulations, to the rules and regulations promulgated under the authority of the Federal Trade Commission. The U.S. Congress has considered, but not yet passed, several comprehensive federal data privacy bills over the past few years. Additionally, several federal agencies have issued rules, regulations or other forms of guidance that may impact the privacy and security obligations that apply to our operations. We expect that the federal government’s approach to data privacy and security rules and regulations will continue to evolve in the coming years.

At the state and local level, there is increased focus on regulating the collection, storage, use, retention, security, disclosure, transfer and other processing of confidential, sensitive and personal information. In recent years, many states have proposed or enacted new laws or amended existing laws and we have seen significant changesexpect them to datacontinue to do so in the future. As the state privacy regulations acrosslaws becomes increasingly complex, we expect the U.S., including the enactmentcost and effort of complying with all of the California Consumer Privacy Act of 2018 (CCPA), which went into effect in January 2020. The CCPA increases privacy rights for California residentsrequirements to increase and imposes obligations on companies that process their personal information, including an obligation to provide certain new disclosures to such residents. The CCPA provides for civil penalties for violations, as well as a private right of action for certain data breaches that result in the loss of personal information. This private right of action may increase the likelihood of and risks associated with, data breach litigation. The CCPA was amended in September 2018 and October 2019, and further amendments may be enacted. In November 2020, California approved the California Privacy Rights Act (CPRA), which creates a new privacy oversight agency and further amends the CCPAcompliance failures to provide additional rights to consumers to access, edit and control the sale and sharing of personal information.

In 2021, two additional states—Virginia and Colorado—enacted comprehensive data privacy laws that will go into effect in 2023, while legislatures in several additional states considered data privacy laws. These laws impose, or have the potential to impose, additional obligations on companies that collect, store, use, retain, disclose, transfer and otherwise process confidential, sensitive and personal information, and will continue to shape the data privacy environment nationally. Although there are similarities between the data privacy laws enacted in California, Virginia and Colorado (along with the laws that have been proposed in other states), there are also substantive aspects of the laws that differ markedly. This lackrise. Lack of uniformity of laws and regulations, which we expect to continuewill increase as othervarious states and countries enact data privacy laws, creates significant legal complexities for companies (such as TriNet)like TriNet that operate nationwide and are required to comply with a patchwork of privacy laws. Moreover,in India and Canada. Also, all 50 U.S. states, the District of Columbia, Guam, Puerto Rico, the Virgin Islands and Canada have enacted data breach notification laws that may require us to notify WSEs, HRIS Users, clients, employees,colleagues, third parties or regulators in the event of unauthorized access to or disclosure of personal or confidential information. Complying with existing and new data privacy and security regulations could cause us to incur substantial costs or require us to change our business practices in a manner adverse to our business. Any failure to comply with existing and new data privacy and security regulations could result in significant penalties, damage our reputation and otherwise have a material adverse effect on our business.

PEO Licensing Laws
Nearly all states have adopted laws and regulations for licensing, registration, certification or recognition of PEOs and the IRS has implemented a voluntary federal certification program for PEOs. We expect states without such laws and regulations to adopt them in the future. While these laws and regulations can vary widely, most regulators monitor the financial health and other relevant business information of PEOs on an annual or quarterly basis. In some cases, these laws and regulations codify and clarify the co-employment relationship for certain payroll, unemployment, workers' compensation and other employment-related purposes or require specific client contractual terms and/or WSE disclosures. We believe we comply in all material respects with the applicable PEO laws and regulations in each state and jurisdiction in which we operate.provide PEO services.
Every state regulates insurance practices conducted within their jurisdiction. While we do not broker insurance, certain of our PEO and HRIS services involve assisting our clients in obtaining and managing employee benefits. We partner with brokers to provide these services and have elected to obtain state insurance licenses as a result. As each state’s licensing requirements differ, maintaining current licenses is complex and we are subject to insurance audits, investigations and fines if we fail to comply with insurance license requirements.
Other state regulatory authorities impose licensing requirements on companies involved in the transmission of cash, such as banks, and other money transmitters. We do not believe that our current activities require any such licenses, but we and others in our industry have received inquiries from regulatory authorities in the past and could receive them in the future.
For additional information on the impact of licensing laws, refer to Part I, Item 1A. Risk Factors, of this Form 10-K, under the heading "If we do not comply with our regulatory license requirements, or if we are deemed to be operating in various non-PEO licensed industries without the required licenses, we and our clients could be adversely impacted".

Payroll Taxes, Unemployment Taxes and Payroll Tax Credits
We must also comply with the federal and state payroll tax and unemployment tax requirements that apply where our clients are located. Tax reform efforts, and other payroll tax changes, at the federal, state and local level can impact our payroll tax reporting obligations for our clients and the services we can provide. State unemployment tax rates vary by state based in part on prior years’ compensationtotal wages, unemployment taxes paid and unemployment claims experience and may also vary based on the overall claims experience of a PEO.PEO in states in which we are required to report and pay unemployment taxes using one of our accounts and rates. As a result, depending on where client WSEs perform services for our clients, are located, the fees we charge PEO clients for unemployment taxes can be higher or lower than a client could obtain alone.without use of a PEO. In some cases, taxing authorities can retroactively increase the unemployment taxes we pay to cover deficiencies in the unemployment tax funds. We also rely on our clients to accurately reportinform us of the work and residence locations for their WSEs' work locationsWSEs and HRIS Users, and inaccurate reporting,information, whether due to remote work from home policies during the COVID-19 pandemic or otherwise, can impact our payroll tax obligations and the obligations of our clients, WSEs and WSEs.HRIS Users.
We have seen a growing trend, particularly at the federal level, of using payroll tax credits, deferrals and other related payroll tax programs as a mechanism for incentivizing SMB development and/orand economic recovery. These programs are popular because they allow SMBs, which often have business income tax losses, to realize benefits via payroll tax reductions, rather than business income tax reductions. As a result, many of our SMB clients demandrequire that we support these programs. Examples of these programs include the federal 2015 PATH Act, whichCARES Act and FFCRA Act. The PATH Act allows SMBs to use research and developmentR&D tax credits submitted on the SMB’s business income tax return to reduce certain payroll taxes, and thetaxes. The CARES Act and FFCRA Act introduced payroll tax creditcredits and payroll taxemployer Social Security deferral programs enacted in 2020 and 2021, which allowthat allowed SMBs to defer certain payroll tax obligations to a later date or to receive payroll tax reductions and refunds or to defer the employer portion of Social Security based on SMBqualifications and employment practicespractices.
We act as the employer of record for federal payroll tax reporting for our PEO clients. This means that are beyond a PEO’swe file client tax credit claims, and pass the associated tax credit refunds to our clients based on information supplied by our clients, which we do not control. These programs have generally not been designed with the PEO industry in mind and these programs are subject to broad agency interpretations given their complexity. While our clients are contractually responsible to us for their errors in tax credit submissions and for repaying us for all rejected tax credits under our service contracts, taxing authorities may still look to TriNet for repayment and we may not be able to effectively enforce or collect on these obligations. For additional information tax credit programs, and the risks they post to our operations, refer to Part I, Item 1A. Risk Factors, of this Form 10-K, under the heading - "Our business is subject to numerous complex laws, and changes in, uncertainty regarding, or adverse application of these laws could negatively affect our business."
Other Employment Regulations
We must also comply with labor and employment laws, which can change frequently at the federal, state and local level. In particular for our PEO services, regulatory focus on the classification of employers, employees and independent contractors has the potential to significantly change how we and other PEOs operate and the services that we and other PEOs can provide to our clients and WSEs. For example, in September 2019, California passed AB5, a law that could potentially reclassify client independent contractors as employees by establishing the ABC testStates continue to determine if a worker is an employeeconsider, or independent contractor for most occupations. On September 30, 2021, and effective January 1, 2022, California expanded the number of occupations exempt from the ABC test. In November 2020, California voters passed Proposition 22, which supersedes AB5 for certain types of contractors. On August 20, 2021, a California state court found that portions of Proposition 22 were unconstitutional and further held that the entirety of Proposition 22 was unenforceable.

The legal landscape is also in flux at the federal level. In 2020, the DOL issued a rule changingguidance around the definition of employers, employees and independent contractors and any change in these definitions may impact our ability to provide certain PEO and HRIS services to certain employers or employees.
We must also comply with state and federal rules and guidelines around both independent contractor and joint employer used understatus. Standards for determining independent contractor and joint employer status vary from law to law and state to state, and changes to and new interpretations of these standards can limit the Fair Labor Standards Act (FLSA)client workers to which was later rescinded in 2021. The National Labor Relations Board (NLRB) announced plans to createwe can provide services and increase the likelihood of claims that we are a joint employer of client WSEs or an employer of HRIS Users. For example, In January 2024, the DOL proposed a new rule for determining independent contractor status and in 2022August 2023, the DOL proposed new regulations that address the salary requirements for white collar minimum wage and overtime exemptions under the FLSA. Meanwhile, the NLRB also modified its own independent contractors test in June 2023 and issued a new standard for determining whether two businesses are joint employers under the National Labor Relations Act (NLRA), while the DOL plans to start on a new rule to raise the salary required for the executive, administrative and professional exemptions under the FLSA.NLRA in October 2023.

We regularly conduct surveys to seek feedback from our colleagues on a variety of topics, including confidence in company leadership, competitiveness of our compensation and benefits package, career growth opportunities and opportunities to improve the attractiveness of our company with existing and potential colleagues. The results are shared with our colleagues and reviewed by senior leadership, who analyze areas of progress or deterioration and prioritize actions and activities in response to this feedback to drive meaningful improvements in colleague engagement. None of our corporate colleagues are covered by a collective bargaining agreement.

Attracting and Retaining Ourour Colleagues

We must attract, develop and retain highly motivated and qualified colleagues to continue to provide the services that our clients need, to achieve our strategic objectives, and to grow our business. We do this by:
offering competitive compensation and benefits packages, including comprehensive health benefits and our 401(k) retirement savings plan, with an immediately vested employer match of up to 4% of cash compensation,
supporting a pay for performance culture through the use of cash and equity incentives tied to the performance of our company and individual performance,
offering an employee stock purchase planESPP that allows our colleagues to purchase our shares at a discount to market value, which fosters a stronger sense of ownership and aligns the interests of our colleagues with our stockholders,
investing in the professional growth of our colleagues with tuition and continuing education reimbursement, wellbeing programs, and comprehensive training and development activities and opportunities both inside and outside of our company,
creating and maintaining a diverse and inclusive colleague base by, for example, the use of colleague-led resource groups and by launching a new diversity and inclusion training curriculum for our colleagues, in 2020, and
supporting workplace flexibility for our colleagues during the COVID-19 pandemic by adopting work-from-homeremote work policies, halting non-critical travel, and providing additional paid time off, employee assistance plans, and access to telemedicine services.

We refer to our employees that are co-employed with our clients as our worksite employees (WSE). For more information about how we help our PEO and HRIS clients manage their own human capital resources and satisfy their own HR-related needs, see the section above titled “Our Services”.

The Impact of Seasonality on Our Business
Our business is affected by seasonality in client business activity, hiring and WSE benefit selection,selections, health claims costs and payroll taxes:
ClientsPEO clients generally change their payroll service providers at the beginning of the payroll tax and benefits enrollment year; as a result, we have historically experienced our highest volumes of new clients joining and terminating clients in the month of January. Our HRIS clients are generally less affected by these considerations.
WSEs select our TriNet-sponsored benefit plans during their respective open enrollment periods, which occur throughout the year. We have historically experiencedgenerally experience the largest proportion of WSE benefit changes in the first quarter and fourth quarter.second quarters.
Health claims costs tend to increase throughout the year as the utilization of medical services above each WSE's deductible causes our insurance costs to increase. In addition, the overall use of medical services by WSEs, including elective procedures, tends to increase later in the calendar year. During the COVID-19 pandemic, we observed significant fluctuations in the typical seasonal use of medical services by our WSEs. The COVID-19 pandemic and emerging variants may continue to cause variability in our WSE's medical services utilization that may result in changes in this seasonal trend in our business.
Certain payroll tax related billings are based on the WSE's annual taxable wage basebases up to a set cap. WSEs and HRIS Users frequently meet these wage base caps in the first two quarters of the year, depending on the WSE's compensation level, resulting in lower related billing contributions to PSR in the latter half of the year.
Our Owned and Licensed Intellectual Property

RISK FACTORS

Item 1A. Risk Factors
Below is a discussion of the risks that we believe are significant to our business. These risks are not the only ones we face. We may face additional risks that we do not currently consider to be significant or of which we are not currently aware, and any of these risks could cause our actual results to differ materially from historical or anticipated results. You should carefully consider these risks along with the other information provided in this Form 10-K, including the information in "Management's Discussion and Analysis of Financial Condition and Results of Operations" and our accompanying consolidated financial statements, as well as the information under the heading "Cautionary Note Regarding Forward-Looking Statements" before investing in any of our securities. We may amend, supplement or add to the risk factors described below from time to time in future reports filed with the SEC.
Risks Related to the COVID-19 Pandemic
The economic, health and business disruption caused by the COVID-19 pandemic continues to impact our business and could result in a material adverse effect on our business, results of operation and financial condition.
The COVID-19 pandemic has resulted in an economic slowdown and, while there have been signs of economic recovery in 2021, the pandemic continues to disrupt our business and the businesses of our SMB clients. We cannot predict or control all of these disruptions, and any such disruptions may have a material adverse effect on our financial condition and results of operations.
Any of the COVID-19 related risks below could have a material adverse effect on our business, results of operations or financial condition. We cannot predict the duration and scope of the pandemic (including the emergence of new variants), the impact of the pandemic on the national and global economy, the duration of the economic downturn, government response to the pandemic and our ability to support laws and programs intended to help SMBs, and whether our clients' businesses will contract or fail due to the pandemic. Any of these factors could exacerbate the risks and uncertainties identified below.
Actual and potential impact on clients and prospects
The change in the economic environment due to the COVID-19 pandemic has had, and may continue to have, an adverse economic impact on our clients and potential clients. We have seen, and expect to continue to see, affected businesses freeze headcount, furlough and terminate employees, and partially or completely shut down business operations. Impacted businesses have faced and we expect many will continue to face liquidity issues, reduced budgets, or an inability to pay for our services or the same level of our services. For example, in the second quarter of 2020, our new sales growth declined and we experienced higher WSE attrition than prior periods. See the risk factor titled “Our clients are particularly affected by volatility in the financial and economic environment, which could harm our business” below for more details.
Actual and potential impact on insurance costs
The COVID-19 pandemic has changed how and when our WSEs incur health expenses. We have experienced and expect to continue to experience higher than normal volatility and variability in the amounts that we pay for group health insurance expenses incurred by WSEs within our deductible layer under our risk-based health insurance policies.
For example, during the third quarter of 2021, we saw increased constraints on access to medical services and systems, particularly in regions that saw increases in COVID-19 hospitalizations. These constraints reduced preventative and elective procedures, resulting in a decrease in our MCT, defined as changes in participant use of services, including the introduction of new treatment options, changes in treatment guidelines and mandates, and changes in the mix, unit cost and timing of services provided to plan participants. This decrease resulted in a lower than normal Insurance Cost Ratio during that period.
It is difficult to predict the rate at which the use of medical services will change as new variants emerge and individual, provider network and government reactions to those variants change. COVID-19 testing, treatment and vaccination costs also make it more difficult to predict future health claims costs, and actual claims patterns and cost trends may differ significantly from our historical experience. Because we assume the risk of variability in future health claims costs for our enrollees under our risk-based health insurance policies, this unpredictability could result in higher-than-expected insurance costs, which could have a material adverse effect on our business, results of operations and financial condition.
As we set our benefit services fees for health and welfare benefits in advance for a fixed benefit period, if actual MCT exceeds our projections, this would result in a higher Insurance Cost Ratio, which could have a material adverse effect on our business, results of operations and financial condition. For details on how the volume and

severity of insurance claims and MCT impact our insurance costs, refer to Critical Accounting Judgments and Estimates in Part II, Item 7. MD&A and the risk factor titled “Unexpected changes in workers’ compensation and health insurance costs and claims by worksite employees could harm our business” below.
In response to COVID-19, many states have adopted standards intended to extend workers’ compensation coverage to claims based on a diagnosis of COVID-19. Most states have focused on providing coverage for first responders, frontline healthcare workers and other essential workers. We are responsible for the deductible layer under our workers’ compensation policies, and our insurance costs are affected by our WSEs' workers’ compensation insurance claims experience. Any law or legal standard that increases the number of covered workers’ compensation claims under our insurance policies could have a material adverse effect on our insurance costs and financial condition. See the risk factor titled “Unexpected changes in workers’ compensation and health insurance costs and claims by worksite employees could harm our business” below for more details.
Actual and potential impact of the laws affecting our industry and clients
New laws and programs have been enacted, and may continue to be enacted, at every level of government to help the economy, employers and employees. For example, the 2020 FFCRA and CARES Act and the 2021 PPPFA and ARPA, and subsequent agency guidance related to those acts, created the paycheck protection program (PPP), mandatory employee leave requirements, payroll tax deferral and tax credit programs, COBRA premium assistance facilitated via employer payroll tax credits, and other employment- and employment tax-related incentives. SMBs must rely on PEOs to help take advantage of these programs, and new and amended laws adding programs or changing existing programs may be passed at the federal, state, and local level at any time.
Most of these laws and programs have not been, and we do not anticipate will be, enacted with the PEO industry in mind. As a result, we cannot guarantee we will be able to support any of these laws and programs in a timely and cost effective manner or at all, which could reduce or eliminate the attractiveness of our services and/or affect the ability of our clients and WSEs to fully realize the benefits of these laws and programs, which would have a material adverse effect on our business, financial condition and results of operations. See the risk factor titled “Our business is subject to numerous complex laws, and changes in, uncertainty regarding, or adverse application of these laws could negatively affect our business” below for more details.
Operational Risks
Unexpected changes in workers' compensation and health insurance costs and claims by worksite employees could harm our business.
Our insurance costs, which comprise a significant portion of our overall costs, are significantly affected by our WSEs’WSEs health and workers' compensation insurance claims experience. OurWe use fully insured risk-based, and fully insured guaranteed-cost, insurance plans are provided by third-party insurance carriers. Under risk-based policies, we agree to reimburse our carriers under risk-based or underfor any claims paid within an agreed-upon per-person deductible layer up to a maximum aggregate exposure limit per policy. These deductible dollar limits and maximum limits vary by carrier and year. Under guaranteed-cost insurance policies.policies, our carriers establish the premiums, and we are not responsible for any deductible. Refer to Note 1 in Part II, Item 8. Financial Statements and Supplementary Data, of this Form 10-K for further discussion of these policies.
Under our risk-based health insurance policies, which make up the majority of our health plans and claims paid in 2023, we assume the risk of variability in future health claims costs for our enrollees. We have experienced variability, and may experience variability in the future, in the amounts that we are required to pay for group health insurance expenses incurred by WSEs within our deductible layer under these risk-based policies, based on changing trends in the volume and severity of medical and pharmaceutical claims.policies. This variability arises from changes to the components of MCT. TheseMCT, defined as changes in participant use of services, including the introduction of new treatment options, changes in treatment guidelines and mandates, and changes in the mix, cost of providing treatment, and timing of services provided to plan participants. MCT trends change over time, and other seasonal trends and variability may develop, which makes it difficult for us to predict this aspect of our business and our failure to accurately predict these trends could have a material adverse effect on our business, financial condition and results of operations. For example, while the amount of medical claims we experienced in 2023 increased as compared to 2022, our insurance costs remained slightly below expectations, which still had a significant impact on our results due to volume.
Under our fully-insuredfully insured workers' compensation insurance policies, we assume the risk for losses up to $1 million per claim occurrence (deductible layer). Refer to Note 1 in Part II, Item 8. Financial Statements and Supplementary Data, of this Form 10-K for further discussion of these policies. The ultimate cost of the workers’ compensation services provided will not be known until all the claims are settled. If we do not accurately predict the risks that we assume, we may not charge adequate fees to cover our costs, which could reduce our net income and result in a material adverse effect on our business. Our ability to predict these costs is limitedimpacted by unexpected increases in frequency or severity of claims, which can vary due to changes in the cost of treatments or claim settlements.
We accrue for the estimated future costs of reimbursing our workers' compensation and health insurance carriers under our insurance policies, usingpolicies. We use internal actuaries to develop health claims estimates and we use external actuaries and our own experience to develop theworkers’ compensation estimates, but the volume and severity of claims activity is inherently unpredictable.difficult to accurately predict. Estimating these accrued costs requires us to consider a number of factors, such as the components of MCT, seasonal trends and the impact of events like the COVID-19 pandemic, which requires significant judgmentjudgment. In addition, the usefulness of historic claims data is impacted by our rates of WSE and ifclient turnover and we renew our estimates are wrong,carrier contracts and set fees in advance of benefit periods.
In past periods, we have experienced insurance costs that were either higher or lower than our expectations and estimates. If we were to experience either outcome in the future, it could result inhave a material adverse effect on our business, financial condition and results of operations.
TRINET172021 FORM 10-K
operation. Higher-than-expected insurance costs result in lower net income. Because we set fees in advance of plan periods, lower-than-expected insurance costs can be an indicator that insurance costs are developing more slowly than our projections, which are reflected in our fees, and this can have a negative impact on client retention and new sales.


RISK FACTORS

IfIn addition, claims are not static and if we subsequently receive updated information indicating that the volume and severity of insurance claims were higher or lower than previously estimated and reported, our insurance costs could be higher or lower, respectively, in that period or subsequent periods as we adjust our accrued costs accordingly, which could have a material adverse effect on our business, financial condition and results of operations. We have experienced both favorable and unfavorable insurance cost variability due to claims activity in the past and could have similar or worse experiences in the future. Refer to Critical Accounting Judgments and Estimates in Part II, Item 7. MD&A, of this Form 10-K for further discussion of these estimates.

RISK FACTORS

Our co-employment relationship with our worksite employees exposes us to unique business risks.
We are theAs a co-employer of our WSEs. As the co-employer of ourclient WSEs, we assume some of the risks and obligations of an employer. For instance, in the past we may needhave been required to provide access to health benefits to our WSEs even ifwhen the cost of providing those benefits exceedsexceeded the service fees received from our clients. The extent of our responsibility for other aspects of our co-employer relationship with our WSEs remains subject to regulatory uncertainty at the federal, state and local levels. For example, underin certain circumstances, we may bestates, PEOs are responsible for paying salaries, wages and related payroll taxes of our WSEs, even if our clients have not timely remitted payments to us.us whether due to insolvency, their bank going into receivership, or other events that may be out of our control.
Our WSEs work in our clients' workplaces. Our ability to control the workplace environment of our clients is limited. Yet, we may be subject to liability for violations of labor and employment laws, workers' compensation laws, industry-specific laws that apply to the businesses our clients operate, and other laws that apply to our clients or to employers generally. We may also be liable for acts, omissions or violations by our clients or WSEs, even if we do not participate in such acts, omissions or violations.
We seek to mitigate these risks through our client agreements and insurance coverage and by requiring certain clients to pre-fund certain obligations.coverage. Our client agreements with our clients divideallocate responsibilities between us and our clients and provide that our clients will fund certain obligations in advance and indemnify us for any liability attributable to their own or our WSEs' conduct. However, we may not be able to effectively enforce or collect on these obligations. In addition, we maintain insurance coverage, including workers’ compensation and EPLI coverage, to limit our and our clients' exposure to various WSE-related claims. Subject to split by contract, weWe are still responsible for any deductible layerlayers under such insuranceour EPLI policies, and such insurancethese policies generally excludesexclude coverage for claims relating to the classification of employees as exempt or non-exempt, other wage and hour issues, and employment contract disputes. We cannot assure you that our insurance will be sufficient in amount or scope to cover all claims that may be asserted against us and for which we are unable to obtain indemnification from our clients.
Negative publicity relating to events or activities attributed to us or our corporate employeescolleagues as a result of the actions of our clients and WSEs, or others associated with them, whether or not justified, may tarnish our reputation and reduce the value of our brand. In addition, if our brand, is negatively impacted, it maywhich could have a material adverse effect on our business, including creating challenges in retaining clients or attracting new clients and hiring and retaining employees. 
In addition, federal and state positions regarding co-employment relationships can change, and have frequently changed in the past, with varying degrees of impact on our operations. We cannot predict when changes will occur or forecast whether any particular future changes will be favorable or unfavorableability to our operations. Any such changes could increase our potential liability for the risks outlined above, or otherwise reduce or eliminate the attractiveness of using a PEO, or significantly increase our compliance costsattract and the cost to provide our services, which could result in a material adverse effect on our financial condition and results of operations.retain clients.
Our SMB clients are particularly affected by volatility in the economic environment.
Our clients are small and medium-size businesses that we believe areSMBs can be particularly susceptible to changes in the level of overall economic activity in the markets in which they operate. These businesses are often exposed to credit and cash liquidity risks, including exposure as a result of the failure of their financial institutions, that larger businesses may be able to avoid, and during periods of weak economic conditions, small businessincluding periods of increased inflation and increased borrowing costs, SMB failures tend to increase, and employment levels tend to decrease. During these periods, our clients have in the pastcan and may in the futuredo freeze hiring, terminate their employees, and reduce employee headcount, compensation and/orand benefits levels, any of which couldwould negatively affect our revenues and margins if we are unable to reduce our operating expenses sufficiently or quickly enough. During these periods, we have also seen in the past and expect to see, during such periods in the future, clients terminatingreduced demand for our services, and/orincreased client terminations, fewer new clients.clients, and clients seeking to renegotiate our contracts and prices. When our clients leave us or reduce their headcount, we typically see increases in the volume and severity of unemployment and relatedclaims, COBRA claims, costs that wedisability claims, and workers’ compensation claims. We may be unable to recover costs related to these claims based on the fees established in our client service agreements.agreements, and any failure to recover such costs may have a material adverse effect on our business, financial condition and results of operations.
We lose clients for many reasons that we cannot control or easily predict and, generally, our clients sign service agreements that they can cancel on short notice.
TRINET182021 FORM 10-K


RISK FACTORS

Our standard client service agreementagreements can generally be canceled by our clients (or us) with 30 days’ prior written notice. We regularly experience client attrition and decreases in new client sales due to a variety of factors that are difficult for us to control or predict, including the overall national economic conditions, client mergers and acquisitions, increaseschanges in our administrativemedical utilization and benefit services fees,related costs, client business failure and liquidity issues, the effects of competition, and client decisions to administer all or a portion of their HR needs in-house or via a non-PEO solution.without using our services. If we were to experience WSE or client attrition for any of the above reasons in excess of our historic or expected rates, or if we incorrectly estimate the impact of the above factors on WSE or client attritionand estimated rates it could have a material adverse effect on our business, financial condition and results of operations.
Geographic and industry market concentration makes our results of operations vulnerable to regional and industry-specific economic and health factors.
PEO services remain our core business. Our top five PEO markets, California, New York, Florida, Texas and Georgia,Massachusetts, accounted for approximately 60%64% in aggregate of our paid WSEs for the year ended December 31, 2021.2023. If any of those geographic regions suffers a downturn, even if the economy at the national level remains strong, or experienceexperiences higher than expected medical services utilization, due to regional health issues, including as a result of the COVID-19 pandemic, the portion of our business attributable to clients in that region could be adversely affected, which could have a material adverse effect on our financial condition or results of operations.
TRINET18 2023 FORM 10-K


RISK FACTORS

In addition, most of our PEO clients operate in a relatively small number of industries,verticals, including the technology, professional services, financial services, life sciences and not-for-profit industries.verticals. As a result, if any of those specific industriesverticals, or any industry within one of those verticals, suffers a downturn, even if the economy at the national level remains strong, the portion of our business attributable to clients in that industry could be adversely affected, which could have a material adverse effect on our business, financial condition or results of operations.
Any failure in our business systems, or in any third-partythe business systems or service providercenters that we or our service providers rely upon, could reduce the quality ofnegatively impact our business services,clients, harm our reputation and expose us to significant, unanticipated liability.
Our business is highly dependent on in-house and third-party data processing centersbusiness systems and systems that relyservice centers. The operation of our business relies on the complex integration of numerous hardware and software subsystems across several service centers to manage a large volume of daily client, WSE and WSE transactions,HRIS User transactions. For example, we rely on software systems, including the processing of employee,software systems used by our banking institutions, to process payroll, payroll tax and benefits data. We also rely on third-party systemsdata and make related payments, and to provide services for our clients and WSEs, includingaccess insurance carrier networks and databases that manage theWSE and HRIS User benefits provided to, and claims made by,claims. These software systems run on computer hardware that we or our clients and WSEs and electronic banking systems and payroll tax systems that transmit payments and data to clients, WSEs and taxing agencies. service providers house in various service centers.
These centers and systems have been, and could be disrupted by equipment failures, computer server or systems failures, network outages, ransomware attacks and other malicious acts, software errors or defects, vendor performance problems, banking failures, power failures, natural disasters, terrorist actions or similar events. We have, alsofor example, experienced office closures on the East Coasteast coast on multiple occasions over the past few years due to hurricane and storm threats, in Texas due to climate-related power grid issues, and in California due to increased wildfire threats in the state. Our offices and data processingservice centers in these and other locations will continue to face the risk of closure or damage in the future due to climate change.related events.
Any delay or failure in our business continuity response to these events, or in the response of our third-party service providers,such disruption, even if only for a short period of time and even if we are not at fault, can have a significant impact on our clients, WSEs and WSEs.

We also rely on enterprise software applications licensed from third parties that are updated from time to time. Any failure of these systems for any reason could delay or prevent us from providing services to our clients, which would have a material adverse effect on our business and results of operations.

In responseWe offered various discretionary credits to the COVID-19 pandemic, we created several programseligible clients in 2020, 2021 and 2022. These credits were based on TriNet health insurance costs over specified periods and were intended to assist in the economic recovery of our existing SMB clients and enhance our ability to retain these clients. These programs are designedduring the COVID-19 pandemic, to promote client loyalty and incentivize client retention, and to differentiate TriNet from its peers in the PEO industry and in other competing HR services industries. However, these programs are also associated with significant costs,We did not offer discretionary credits in 2023 and do not have plans to in the future. While we cannot guarantee that we will recover these costs, or achieve our intendedbelieve the discretionary credits created some client loyalty and retention, and product differentiation goals from these programs.

Eligible clients received one-time reductions against fees for future services, accounted for as a discount, to be received over the following 12 months. As a resultretained because of the Recovery Credit, we reduceddiscretionary credits to leave. Client attrition due to the stoppage of the discretionary credits could reduce our total revenues by $128 million in 2020 and $17 million in 2021.

Adverse changesChanges in our insurance coverage, or in our relationships with key insurance carriers, could harm our business.
Our success depends in part on our ability to maintain competitive health and workers' compensation coverage options and insurance rates through well-known insurance carriers. If we are unable to maintain competitive insurance rates or obtain popular and desirable coverage plans through well-known insurance carriers, it could affect our ability to attract and retain clients, which could have a material adverse effect on our business. Where we sponsor insurance coverage and we are not responsible for any deductibles, our carriers set the fixed cost of the plan, which may lead to uncompetitive fees. Even where we sponsor insurance under which we are responsible for deductibles, we may not be able to control our costs in a way that would make our fees competitive.
In addition, broad adoption of our services in certain geographic regions or industries may make it more difficult for us to obtain competitive health and/or workers' compensation insurance rates due to concentration of clients within a particular region or industry. For example, we have significant concentrations of PEO clients in California, New York, Florida, Texas and Georgia,Massachusetts, which account for approximately 60%64% in aggregate of our paid WSEs for the year ended December 31, 2021.2023. The loss of any one or more of our key insurance vendors in these areas, or our inability to partner with certain vendors that are better-known or morethe most desirable to our clients or potential clients,carriers in these areas, could have a material adverse effect on our financial condition and results of operations.
We must continue to work to improve our services to meet the expectations of our clients and regulators, or we may lose our clients and materially harm our business.
In order to attract and retain clients, we believe that we must compete in our industry effectively on the basis of the value proposition that we deliver to our clients, including which includes

RISK FACTORS

client experience and satisfaction,
the relevance and cost-effectiveness of our PEO benefit plans,
our PEO vertical market expertise, total price of
our service and product pricing,
our brand awareness and reputation,
our ability to innovate and respond to client needs and regulatory mandates rapidly, access to
the performance of our online and mobile solutions, software and technology platforms, and
our human resources subject matter expertise.
The expectations of our clients and prospective clients in these areas change over time as a result of many factors outside of our control, such as competition, regulatory and technical changes, and changing trends in the demands employees place on SMB employers. Regulatory changes may also mandate that we make changes to our services or benefit offerings.
To satisfy client expectations and regulatory requirements, we must timely and effectively identify and develop, or license and contract appropriate technologies and services, and incorporate themsuch technologies and services into the solutions that we provide. New services or upgrades may not be released according to schedule or may contain defects when released. Difficulties with the performance ofIf our new technologies and services perform poorly, or our abilityfail to satisfy changes in regulatory requirements, we could result inexperience client dissatisfaction, adverse publicity, loss of sales, delay in market acceptance of our services, orand client claims against us, any of which could materially harm our business. For example, like other PEOs, our federal R&D tax credit programs require the IRS to provide tax credit refunds for our clients. In situations where IRS refunds were delayed, even where we were not at fault, we have experienced client terminations and dissatisfaction, and we may experience similar outcomes in the future. Even ifwhere we are capable of satisfyingcan satisfy client expectations in these areas,and regulatory requirements, we may not be able to do so on a cost-effective basis, which could have a material adverse effect on our financial condition and our results of operations. We could lose market share if our competitors develop superior productstechnologies and services or satisfy client or regulatory demands before we are able to do so. If we are unable to satisfy the evolving producttechnology and service expectations and regulatory requirements, then we wouldmay experience lower client satisfaction, fewer new clients and higher client attrition, which could have a material adverse effect on our business.
We have acquired, and may in the future acquire, other businesses and technologies, which can divert management's attention and create integration risks and other risks for our business.
We have completed numerous acquisitions of other businesses and technologies over the years, and we expect that we will continue to pursue future acquisitions. On December 23, 2021, we entered into a definitive agreement to acquire YourPeople, Inc. dba Zenefits. Acquisitions including the potential acquisition of Zenefits, involve numerous other risks, some of which we have experienced in the past and which we may experience in the future, including:
over-valuing and over-paying for businesses and technologies,
increased operating costs and unanticipated costs to successfully integrate the clients, WSEs and HRIS Users, operations, systems, technologies, services and personnel of the acquired business,
establishing or maintaining required internal controls, procedures and policies for the acquired business,
unanticipated costs and risks arising from the unique corporate culture and risk appetite of acquired businesses,
diversion of management’s attention from other business concerns,

RISK FACTORS

litigation resulting from the activities of the acquired business,
insufficient revenues, insurance or seller indemnification to offset increased expenses associated with the acquisitions and unanticipated liabilities of the acquired businesses,

entering markets in which we have no prior experience and may not succeed, and
potential loss of key employees or key clients of the acquired business as a result of the acquisition or integration of the acquired business.
We have experienced increased operating costs to resolve the challenges of prior acquisitions. If we fail to appropriately integrate any acquired business, we may fail to achieve our growth, service enhancement or operational efficiency objectives, and our business, results of operations and financial condition could be harmed.
TRINET20 2023 FORM 10-K


RISK FACTORS

For example, TriNet has focused almost exclusively on the PEO business since its formation and PEO services remain our core business. Our HRIS and tax credit offerings are not PEO businesses. They utilize separate software and technology platforms, and they service SMB clients that can have very different needs from our traditional PEO clients. These businesses may divert management attention from our core PEO business to its detriment. Conversely, we may lack the experience needed in these non-PEO businesses to manage them effectively. Any such outcome could result in a material adverse effect on our business, financial condition and operations have undergone and will continue to undergo significant change as we seekresults of operations.
Our efforts to improve our operational effectiveness and the support, servicesresiliency require significant time, resources and products that we provide to our clients. If our clientscosts and prospects do not acceptif these changes,efforts fail or if we are unable to effectively manage this change,significantly divert management attention, our business and results of operations may suffer.
We have changed our operations and client service processes in recent periods in order to improve our operational effectiveness and to provide improved client support, services and product options,resiliency, and we will continue to do so in the future. For example, in 2020,over the course of 2022 and 2023 we adoptedupgraded and released a new company-wide enterprise resource planning (ERP) system. If our new ERP system does not function as intended and designed, management attention may be diverted, and we may see increased operational costs while we remediate any issues. We are also working on other projects intended to upgrade our technology platform and the client service engagement support model, called Connect 360,tools we use, increase workflow automation, and improve the retention of, and access to, institutional knowledge. For example, over 2023 we expended considerable time and resources on decoupling and modernizing our PEO and HRIS platforms. We will continue to expend considerable resources on these efforts through 2024. If we are unable to achieve our goals, management attention may be diverted and we may experience competitive challenges, client dissatisfaction, program delays and increased operational costs to remediate any resulting issues.
We have and will continue to devote substantial time, money and management resources to these projects. Managing these projects also typically requires changes to our internal operational, financial and management controls as well as our reporting systems and procedures. We cannot guarantee that our efforts will achieve our goals in a timely or cost-effective manner or at all, and we cannot guarantee that we believe will benefitcan carry out these projects without a negative impact on our clientsday-to-day operations and WSEs by providing them with improved support.. Similarly, in 2021, we launched Financial Services Preferred, and a new product, called IOM, that offers clients the option to receive PEO services from TriNet while also obtaining client-sponsored health benefits from a third-party broker that partners with TriNet. We have adopted robust remote work policies and practices during the COVID-19 pandemic. These policies and practices may make it more difficult to manage and implement certain program, service and product initiatives for our clients and their WSEs.client satisfaction. If our clientscurrent and prospects do not acceptfuture projects are delayed or value these support programs, services and products, and other similarunsuccessful, of if any changes we make in the future,to our controls, reporting systems, or procedures are deficient, client satisfaction may suffer, we may lose clients experience reduced onboardingor fail to onboard new clients at expected rates, and see increased operationalwe may incur substantial unanticipated costs any oneto complete these projects. Any of whichthese outcomes could have a material adverse effect on our business, financial condition and results of operations.
In addition, managing these operational and process changes typically requires changes our internal operational, financial and management controls and reporting systems and procedures while we simultaneously seek to effectively recruit, integrate, train and motivate new corporate employees, retain our existing corporate employees, maintain our corporate culture, effectively execute our business plan, satisfy our existing clients, acquire new clients, and enhance the quality and scope of our services. These activities also require significant operating and capital expenditures and allocation of valuable management and employee resources. If we fail to manage these operational and process changes effectively, our costs and expenses may increase more than we expect and our business, financial condition and results of operations may be harmed.

RISK FACTORS

If we are unable to attract, maintain and manage qualified personnel, including our sales force, our business may be harmed.
To succeed, we must be able to attract and retain highly motivated and qualified personnel. Competition for skilled employees is intense and iflike many businesses, we are susceptible to fluctuations in the labor market. For example, as we continue to expand our operations in India, we are also entering a new labor market. If we are unable to attract and retain qualified personnel, in either or both of the personnelUS and India (or any other jurisdiction into which we need,expand), our business may suffer.
For example, like many businesses we have experienced higher than normal rates of employee turn-over during the COVID-19 pandemic and related "great resignation".
We have also experienced elevated sales force attrition in the past and may experience it in the future, for a variety of reasons, including due to changes in industry or client focus, compensation structure, third-party competition for sales talent and other factors.we have experienced elevated sales force attrition in the past and may experience it in the future. Newly hired sales personnel are typically not productive for some period of time following their hiring, which results in increased near-term costs to us relative to their actual sales contributions during this period. If we are unable to effectively train and maintain an adequately seasoned and sized sales force, our revenues likelynew client onboarding will not increase at the rate that we anticipate, which could have a material adverse effect on our business, financial condition and results of operations.
Our industry is competitive, which may limit our ability to maintain or increase our market share or improve our results of operations.
We face significant competition on a national and regional level from other PEOs, ASOs that do not use co-employment relationships, and HRIS software providers, as well as from other existing, and potential, companies and industries that service, or may in the future service, client HRHCM needs. Refer to the heading "Competition"Competition” under Part I, Item 1. Business, above for more details. Our competitors, regardless of industry, may have greater marketing and financial resources than we have, and may be better positioned than we are in certain markets. Increased competition in our industry could result in price reductions or loss of market share, any of which could harm our business. We expect that we will continue to experience competitive pricing pressure.
Moreover, we may not be successful in convincing potential clients that the usepressure and competition from new technologies and HCM service models, any one of our services is a superior, cost-effective means of satisfying their HR obligations relative to the way in which they currently satisfy these obligations either by themselves or by using the services of our competitors. If we cannot compete effectively against other PEOs or against the alternative means by which companies meet their HR obligations, or if we are unable to convince clients or potential clients of the advantages of our offerings, our market share and business may suffer, resulting incould have a material adverse effect on our financial condition and results of operations.business.

Other threats include inadvertent security breaches or theft,disclosure, misuse or unauthorized access or other improper actions by our employees,colleagues, clients, WSEs, HRIS Users, service providers and other business partners. Cyber-attacks, breaches, disclosures and other security-relateddata-related incidents are increasing in frequency and evolving in nature. While we devote substantial time and resources to training our colleagues to identify and avoid such incidents, no training or cybersecurity program can offer absolute protection against such attacks and incidents.

In some cases, weWe perform riskrisk-based assessments of our vendors and service providers, but our assessments may be incomplete or not detect vulnerabilities that can impact our business. Vendors and service providers with access to our data and systems typically undergo additional security review procedures. In addition, we require themthose vendors and service providers to undertake additional security measures through contract provisions.according to the inherent risk of the system access or processing activity contemplated in the contract. However, we do not control our service providers and our ability to monitor their data security is limited, so we cannot ensure the security measures they take will be sufficient to protect our confidential, sensitive and personal information. Due to applicable laws and regulations or contractual obligations, we may be held responsible for any cyber-attack, breach, disclosure or other security-relateddata-related incident attributed to our service providers regarding the information we share with them and any contractual protections we may have from our service providers may not be sufficient to adequately protect us from any such liabilities and losses.losses.

However, the security protections and strategies that we implement, and the investigation and remediation efforts we undertake, may not be successful. The use of artificial intelligence and machine learning ("AI-ML") tools by cyber threat actors may create new types of attacks that are difficult or impossible for our existing security controls to detect and prevent. While we continue to invest in new security tools and technologies that aim to counteract this weaponization of AI-ML, those measures may fall behind the capabilities of the threat actors.

RISK FACTORS

In addition to breach notification laws, we have seen increased focus at every level of government inside and outside of the United States on regulating the collection, storage, use, retention, security, disclosure, transfer and other processing of confidential, sensitive and personal information. For example, in recent years, many states have proposed or enacted new laws or amended existing laws. Certain state laws, including the CCPA and CPRA, may be more stringent or broader in scope, or offer greater individual rights, with respect to confidential, sensitive and personal information than federal, international or other state laws, and such laws may differ from each other, which may complicate compliance efforts, requiring attention to changing regulatory requirements. We believe thatAs the patchwork of privacy laws to which we currently complyare subject becomes increasingly complex, the cost of complying with all of the requirements of the CCPA, but additional provisions of the CCPA became effective in 2021will rise and will become effective in 2023. In 2021 the CCPA went into effect and imposed certain obligations on businesses, such as a requirement to respond to consumer data access requests. We evaluated our obligations under CCPA and ensured necessary compliance. The CPRA, which goes into effect in 2023, may impose additional obligations on us. While we are working to comply with these provisions, we cannot guarantee that we will not incur significant costs or that our compliance efforts will be successful. As a sponsor of employee benefit plans with access to certain PHI, we are subject to regulation at the federal level, including under the HIPAA and the HITECH Act. HIPAA contains restrictions and health data privacy, security and breach notification requirements with respect to the use and disclosure of PHI and there are penalties and fines for HIPAA violations. Additionally, in 2021 the U.S. Department of Labor issued cybersecurity best-practices guidance for sponsors, administrators, service providers and participants of defined contribution retirement plans, which guidance is relevant to the retirement plans we maintain for our corporate employees and worksite employees.

Complying with these and any other data privacy and security laws, rules and regulations, and with any new laws or regulations or changes to existing laws, could cause us to incur substantial costs or require us to change our business practices in a manner adverse to our business, divert resources from other initiatives and projects, and restrict the way products and services involving data are offered, all of which may have a material adverse effect on our business. For example, we have incurred and expect to continue to incur additional costs to comply with the CCPA and other similar regulations. Despite our efforts, in the future we may be unable to make required changes and modifications to our business practices in a commercially reasonable manner, or at all. Given the rapid development of cybersecurity and data privacy laws, we expect to encounter inconsistent interpretation and enforcement of these laws and regulations, as well as frequent changes to these laws and regulations. As a result, we may be required to incur significant, unexpected compliance costs and we may be exposed to significant penalties or liability for non-compliance, the possibility of fines, lawsuits (including class action privacy litigation), regulatory investigations, criminal or civil sanctions, audits, adverse media coverage, public censure, other claims, significant costs for remediation and damage to our reputation, all of which could have a material adverse effect on our business and operations.

Legal and Compliance Risks
Our business is subject to numerous complex laws, and changes in, uncertainty regarding, or adverse application of these laws could negatively affect our business.
The services we provide to our clients are subject to numerous complex federal, state and local laws and regulations, including those described in Part I, Item 1. Business, of this Form 10-K. These laws and regulations cover a diverse range of topics, including employer status, employee and independent contractor classifications, employee benefits, health and retirement plans, workers' compensation, banking and money transmission, employment and payroll tax, worksite safety, insurance, and banking, wage and hour, anti-discrimination, and many topics specific to the industries of our clients. Many of these laws do not specifically address PEOs or co-employment relationships, and regulators are often unfamiliar with the PEO industry and co-employment relationships, which can lead to unpredictable application, interpretation and enforcement of these laws and regulations at the federal, state and local levels in relation to our business. Our HRIS services can also be subject to complex federal, state and local laws and regulations regarding payroll agents, employment and payroll taxes, insurance producers, banking and money transmission, and other licensing requirements. The tax credit support services we provide are also subject to federal, state and local regulations regarding tax preparation and practice that limit the services we can provide to SMBs. While regulations governing HRIS services and tax credit support services do not involve the complexity of a co-employment relationship, these services are in some ways also highly regulated and such regulations can, and do, change regularly at the federal, state and local levels. For example, in mid-January the House of Representatives passed the Tax Relief for American Families and Workers Act of 2024 (TRAFWA) which, if it were to become law, would require that the IRS not accept further claims for the CARES Act Employee Retention Tax Credit (ERTC) after January 31, 2024, which results in a shorter time to file than would normally be permitted under federal filing rules. This change would negatively impact SMBs by terminating the availability of the ERTC early.
Any new laws, changes in existing laws, or any adverse application, interpretation or enforcement of new or existing laws, including those described in Part I, Item 1. Business, of this Form 10-K, whether they apply to employers generally or specifically to PEOs or to our co-employment relationships could:
reduce or eliminate the value and benefits that clients realize by using our services,
change or eliminate the types of services we provide,

increase the cost and complexity of the licensing requirements for our business operations,
create or increase our liability and responsibilities to our clients and WSEs, HRIS Users, and/or
mandate new compliance requirements, disclosures or services.
Any of the above changes could have a material adverse effect on our business, financial condition and results of operations.
For example, we have seen a growing trend, particularly at the federal level, of using payroll tax credits, deferrals and other related payroll tax programs as a mechanism for incentivizing SMB development and/orand economic recovery. These programs are popular because they allow SMBs, which often have income tax losses, to realize benefits via payroll tax reductions, rather than income tax reductions. However, these programs have generally not been designed with the PEO industry in mind and rely on calculations contained in client income tax returns (whichwhich PEOs do not process in their role as the co-employer) and/co-employer or other client data that cannot be verified by a PEO, even though the resulting tax benefits are processed through the PEO’s payroll tax returns. Because minimal guidance exists in the statutes that create these programs, they are subject to broad and varied agency interpretation and confusion.application. In addition, the processes used to evaluate payroll tax filings are designed with individual taxpayers in mind, not PEOs that aggregate the filings of many clients, which can further increase agency confusionvaried interpretation by agencies and make it difficult to predict agency interpretations.their interpretation and application. For example, we must claim PEO client ERTCs in aggregate on our federal tax filings and such filings are inherently more complex. The constrained timeline in the TRAFWA coupled with the complexity of our federal filings may result in our PEO clients being negatively impacted in a manner that is more significant than the impact that the TRAFWA, if it were to become law, would have on SMBs not using our PEO services.
ExamplesSome of these programs include the 2015 PATH Act, which allows SMBs to use research and developmentR&D tax credits submitted on the SMB’s income tax return to reduce the SMB’s payroll taxes, and the CARES Act and FFCRA Act payroll tax credit and payroll tax deferral programsprogram enacted in 2020 and 2021, which allow SMBs to defer certain payroll tax obligations to a later date or to receive payroll tax credits based on SMB employment practices that are beyond our control. The IRS has taken positions that we and other PEOs, rather than clients, are responsible for client errors and repaying rejected tax credit claims under these and similar programs. While our clients are contractually responsible for repaying us for any rejected tax credits under these programs, a contract does not guarantee our ability to recover rejected tax credits and any failure to recover rejected tax credits from our clients would increase our operating expenses, which could result in a material adverse effect on our financial condition and results of operations. Similarly, and the IRS has taken positions that the tax benefits under some of these programs should be calculated on an aggregate PEO, rather than individual client, basis, which maycan limit our ability towhether and how we obtain full tax benefitscredits for our clients under these and similar programs and/or increase our exposure to credit risk if we are not able to recover excess tax credits paid to our clients. We cannot predict how these positions will ultimately be resolved and if they are resolved unfavorably, we may be forced to discontinue supporting some or all of these programs, and/or incur tax expenses that we cannot recover from our clients, and divert management’s attention to defending our positions, any one of which could have a material adverse effect on our ability to attract and retain SMB clients.clients or on our business, financial condition and results of operations.
These developments,In addition, many states have also implemented assistance programs, such as mandatory employee leave requirements and any other employment- and employment tax-related incentives. Our SMB clients rely on us to help them take advantage of these programs, and new laws, changes inregulations and agency or judicial interpretations of these laws or adverse application or interpretation of laws, including payroll tax incentive programs, could reducechange or eliminate the attractiveness of our services and our ability to supportexisting programs that clients want, provide clients with new and attractive alternatives to our services, significantly increase our compliance costs and the cost to provide our services, requireat any time, which could force us to make substantial changes to the way in whichdiscontinue supporting these programs or incur liability that we operate, or require us to pay client liabilities with no guarantee of subsequent recoverycannot recover from our clients, which could cause us to lose clients and any one of these outcomes could result inhave a material adverse effect on our business, financial condition and results of operations.

Changing laws and regulations governing health insurance and other traditional employee benefits at the federal, state and local level could negatively affect our business.
Changes to and continued uncertainty regarding the implementation and future of health care reform in the United States, at the federal, state and local level, has the potential to substantially change the health insurance market for SMBs and how such employers provide health insurance to their employees, which could have a materially adverse effect on how we provide our sponsored health benefits to our WSEs,, and our ability to attract and retain our clients. In addition, changes at the federal, state and local level to the laws and regulations regarding other traditional employee benefits, such as retirement and workers’ compensation benefits, also have the potential to substantially change the types of benefit programs that are available to SMBs and that we and other PEOs may be

RISK FACTORS

If we are not recognized as an employer of our worksite employees, and if our benefit plans are deemed to not satisfy plan requirements, under federal and state regulations, we and our clients could be adversely impacted.
In order to sponsor certainsome of our most important employee benefit plan offerings for WSEs, including health plans, we must qualify as an employer of WSEs, for certain purposesand our plans must qualify as employer-sponsored plans, under applicable provisions of the Code and ERISA. In addition,particular, our status as the employer for the purposes of ERISA is important for purposes of ERISA’s preemption of certainbecause ERISA preempts state laws. laws that otherwise might apply to, and limit, our benefit plan offerings.
The definition of employer under various lawsthe Code and ERISA is not uniform and under both the Code and ERISA the term is defined in part by different facts and circumstances tests.
tests, and there is no definitive judicial interpretation of employer in the context of PEOs. Generally, thesethe tests used under the Code or ERISA are designed to evaluate whether an individual is an independent contractor or employee, and they provideconfer substantial weight to whether a purported employer has the right to direct and control the details of an individual's work. Some factors that may be considered important under these tests have included the employer’s degree of behavioral control (for example the extent of instructions, training and evaluation of the work), financial control and the economic aspects of the work relationship, the type of relationship, as evidenced by the specific contract, if any, whether employee benefits are provided, whether the work is indefinite in duration or project-based, and whether it is a regular part of the employer’s business. However, a definitive judicial interpretation of “employer” in the context of PEOs has not been established.
We believe that we qualify as the sole employer of WSEs for the purposes of Sections 3(5) and 3(40) of ERISA and that our health plans are single-employer plans that, as such, are entitled to ERISA’s preemption of the application of state law. The DOL, however, has determined on a facts and circumstances basis that certain entities in the HR outsourcing industry do not qualify as common law employers. In addition,However, the DOL routinely audits employee benefit plan offerings of employers, and these audits can take years to complete. Inin one routine audit of one of TriNet’s health plans that concluded in 2021, the DOL has indicated that while it agrees that we are an employer for ERISA purposes, it believes that wherever there is more than one employer of a WSE, no employer may qualify as a single employer for ERISA purposes. Similarly, in 2022, the DOL revised an existing publication regarding regulation of MEWAs and added a new section stating its view that a PEO arrangement offering health coverage to more than one client is a MEWA under Section 3(40) of ERISA. This DOL interpretation is contrary to our interpretation of the applicable ERISA facts and circumstances test, and we understand it also is contrary to the position oftaken by other national PEOs.
We will continue to vigorously defend our position that we are the sole employer of our WSEs for the purposes of Sections 3(5) and 3(40) of ERISA, and therefore that our health plans are single-employersingle employer plans entitled to ERISA’s preemption of applicable state laws. While we have no current DOL audit on-going, regarding this issue and the DOL’s position remains uncertain, and this issueMEWA publication referenced above may arise in future audits of TriNet plans or the plans of other PEOs in our industry. If it were ultimately determined that all health plans sponsored by PEOsTriNet are multiple-employermultiple employer plans and subject to potential regulation at the state level, we would likely adjust our business model and the manner in which we provide employee health benefits to WSEs. Any such outcome or adjustment would require significant investment in time, cost and management attention and would have a material impact on our clients and WSEs and the type of products and services we provide to them, which could have a material adverse effect on our business and results of operations.
As an employer of WSEs under ERISA, we must manage our plans in accordance with ERISA requirements, which could impact how we fulfill plan obligations, how we price services, the features of our benefit plans, and how we administer and operate our plans. We believe that our benefit plans satisfy all applicable ERISA requirements, but if it were ultimately determined that we fail to satisfy any such requirements, we would likely be required to adjust our business model, including with respect to each of the areas outlined above, and could be subject to material fines or penalties. Any such consequence may result in a material adverse effect on our business and results of operations.
We have seen increased state efforts to regulate PEO health plans. For example, new legislation and proposed rules in New Mexico seek to prevent WSEs of small group employers from participation in PEO sponsored large group market health plans, with exception for plans the PEOs register as MEWAs under state law. These rules, and legislation, and any other new or changed rules that treat PEO health plans as multiple employer plans, restrict PEO fees with carriers or that limit the availability of PEO benefit plans, if upheld to be legally valid and applicable to our PEO health plans, would likely require us to adjust our business model in the states with such rules, including the manner in which we provide employee health benefits to WSEs and price our services, and could result in material fines or penalties. Any such outcome or adjustment would require significant investment in time, cost and management attention and would have a material impact on our clients and WSEs and the type of products and services we provide to them, which could have a material adverse effect on our business and results of operations.
Similarly, to qualify for favorable tax treatment under the Code, certain employee benefit plans, such as 401(k) retirement plans and cafeteria plans, must be established and maintained by an employer for the exclusive benefit of its employees. All of our 401(k) retirement plans are operated pursuant to guidance provided by the IRS and have received favorable determination letters from the IRS confirming the qualified status of these plans.their tax-qualified status. However, the IRS uses its own complex, multi-factor test to ascertain whether an employment relationship exists between a worker and a purported employer. Although we believe that we qualify as an employer of WSEs under the Code, we cannot assure you that the IRS will not challenge our position or continue to provide favorable determination letters.
TRINET26 2023 FORM 10-K


RISK FACTORS

Moreover, the IRS' 401(k) guidance and qualification requirements are not applicable to the operation of our cafeteria plans.
Further, if we are not recognized as an employer of our WSEs under the Code or by any state tax authority, we may be required to change the method by which we report and remit payroll taxes to the IRS or such tax authorities. Such changes could have a material adverse effect on our business and results of operations.
TRINET272021 FORM 10-K


RISK FACTORS

The definition of employers, employees and independent contractors is evolving. Changes to the laws and regulations that govern what it means to be an employer or an employee may require us to make significant changes in our operations and may negatively affect our business.
National viewsViews on employers, employees and independent contractors are changing at a rapid rate as evidenced by recentat federal, state and local levels. Any state rule changes. In September 2019, California passed AB5, a lawregulations that could potentially reclassify client independent contractors as employees. In November 2020, California voter passed Proposition 22, which supersedes AB5 for certain types of contractors. On August 20, 2021, a California state court found that portions of Proposition 22 were unconstitutionalchange existing definitions and further held that the entirety of Proposition 22 was unenforceable. Changes like these to the rules in any jurisdiction that define when a worker is an employee or independent contractor can increase or decrease the pool of WSEs that we can co-employ and include in our TriNet sponsored benefit plans, which may negatively impact client demand for the services we provide, require us to modify or change how we operate our business and have a material adverse effect on our business and results of operations.
In January 2020, the DOL issued a new rule broadening the definition of joint employer that has been used under the Fair Labor Standards Act (FLSA) for more than sixty years. In 2022, the National Labor Relations Board (NLRB) plans to create a new rule for determining whether two businesses are joint employers under the National Labor Relations Act (NLRA). Joint employment is not the same as co-employment, and we do not believe that we are a joint employer under the DOL rule or any future NLRB rule, or that these rule changes impact our status as a co-employer. While the DOL rule has been partially vacated by a district court decision, these changes could still potentially result in increased FLSA jointemployment claims, which could divert management attention and cause us to incur additional and potentially material costs to defend.
The examples above highlight the impact to our business when regulations regarding the definitions or classificationclassifications of employers, employees and independent contractors and other groups of workers change. Any such regulatory changes could affect the types of client employees we can support through our PEO and HRIS services, the way in which we provide TriNet-sponsored benefits to our WSEs, the way in which we report and remit payroll taxes to tax authorities, and our legal liability for the actions and inactions of our clients. Any of such regulatory changes could alsoclients, which may negatively impact client demand for the services we provide, require us to modify or change the manner in whichhow we operate our business or provide our services, and could have ana material adverse effect on our business and results of operations.
At the federal level, the DOL published a final rule in January 2024 on independent contractor status. Meanwhile, the National Labor Relation Board (NLRB) modified its own independent contractor standard under the National Labor Relations Act (NLRA) in a decision published in June 2023. In August 2023, the DOL issue a Notice of Proposed Rulemaking addressing the salary requirements for white collar minimum wage and overtime exemptions under the FLSA. In October 2023, the NLRB issued a new standard setting forth its standards under the NLRA for determining joint employer status. Standards for determining joint employer status vary from law to law and state to state. Joint employment is not the same as co-employment, and we do not believe that we are a joint employer under any law or rule, or that these rule changes impact our status as a co-employer. However, continuing uncertainty regarding independent contractor and joint employer status could still result in increased regulatory and worker claims, which could divert management attention and cause us to incur additional and potentially material costs to defend.
Remote work continues to be widely used by employers across the country. The laws and regulations that govern employees were not drafted with remote workers in mind and changes in, uncertainty regarding, or adverse application of these laws could negatively affect our business.
More and more employees, including WSEs and HRIS Users, are working from home and SMBs, including our clients, are increasingly hiring employees in locations where they have not previously had employees and/or permitting existing employees to relocate to other locations and work entirely remotely. Other employees may work at home in one state or city some of the time and in an office in another state or city at other times. The work location and residence of an employee can create confusion regarding the federal, state and local laws that apply, including labor and employment, payroll and payroll tax, and unemployment laws. For example, it can be difficult to determine the amount of payroll and unemployment taxes that must be paid when employees spend part of their time working from home in one state and part of their time working in an office in another state. Regulations regarding payroll and unemployment taxes are still catching up to this new reality, which creates a risk that states will disagree about the taxes that must be paid, or the employment laws that must apply, in these situations. New laws, changes in laws or adverse application or interpretation of laws that depend on the residence and work location of WSEs and HRIS Users could reduce or eliminate the attractiveness of our services, significantly increase our compliance costs and the cost to provide our services, or require us to make substantial changes to the way in which we operate, and any one of these outcomes could result in a material adverse effect on our financial condition and results of operations.
Even where remote workers live and work in the same state and city, as a co-employer of WSEs, our PEO services are open to the risk that new laws, changes in laws or adverse application or interpretation of laws will expand PEO responsibility for remote WSEs.For example, during the COVID-19 pandemic we saw many states extend workers’ compensation coverage to remote employees and to COVID-19 claims. We expect to see additional, similar expansions of PEO responsibility and we cannot guarantee that we will be able to recover the costs to comply with such changes from our clients, which could have a material adverse effect on our business.
If we do not comply with our regulatory license requirements, or if we are deemed to be operating in various non-PEO licensed industries without the required licenses, we and our clients could be adversely impacted.
Most states require PEOs to hold a license and we are licensed as a PEO in all states that require such licenses. If we are not able to satisfy existing or future PEO licensing requirements or other applicable regulations in any state, we may be prohibited from doing business in that state, including having any clients within that state.
In the fourth quarter of 2021, we launched a new product, called IOM, that offers clients the option to receive PEO services from TriNet while obtaining client-sponsored health benefits from a third-party broker that partners with TriNet. TriNet does not broker insurance, but we do maintain producer licenses in all 50 states and select U.S. territories. If we are not able to satisfy existing or future producer licensing requirements, or other applicable regulations in any state, we may not be able to operate this program in the same manner, or we may lose the ability to collect certain administrative fees, within that state.
In addition, stateState regulatory authorities generally impose licensing requirements on companies acting as insurance agents or third-party administrators, such as those that handle health or retirement plan funding and claim processing. TriNet

does not provide broker insurance, but we do maintain producer licenses in all 50 states and select U.S. territories for our HRIS services and for our OMS product family, which offers clients the option to receive PEO services from TriNet while sponsoring their own health benefits obtained through brokers. Other state regulatory authorities impose licensing requirements on companies involved in the transmission of cash, such as banks, and other money transmitters. We do not believe that our current activities require any such licenses, but we and others in our industry have received inquiries from regulatory authorities in the past and could receive them in the future. Businesses similar to our HRIS services have been subject to such licensing requirements in the past and although we believe that our operations have been designed to be compliant and avoid such requirements, we cannot guarantee that all regulators will agree. If regulatory authorities in any state determine that we are acting as an insurance agent, third-party administrator, money transmitter, or as any other regulated industry other than a PEO, we may need to hire additional personnel to manage regulatory compliance and pay annual regulatory fees, which could have a material adverse effect on our financial condition and results of operations.
We are subject to legal and tax proceedings that may result in adverse outcomes.
We are subject to claims, lawsuits, government investigations, and other legal and regulatory proceedings arising from the ordinary course of our business. Refer to Note 109 in Part II, Item 8. Financial Statements and Supplementary Data, of this Form 10-K for additional information about the legal proceedings we are currently involved in and future proceedings that we may face. Current and future legal proceedings may result in substantial costs and may divert management’s attention and resources, which may seriously harm our business, results of operations, financial condition and liquidity.
TRINET282021 FORM 10-K


RISK FACTORS

In addition, the tax authorities in the U.S. regularly examine our tax returns. Refer to Note 1312 in Part II, Item 8. Financial Statements and Supplementary Data, of this Form 10-K for additional details regarding our on-going tax examinations and disputes. The ultimate outcome of tax examinations and disputes cannot be predicted with certainty. Should the IRS or other tax authorities assess additional taxes as a result of theseany audit or other examinations,examination, we may be required to record charges to operations that could have a material impact on our results of operations, financial position or cash flows.
Financial and Stock Ownership Risks
Our results of operations and stock price may fluctuate as a result of numerous factors, many of which are outside of our control.
Our future operating results and stock price are subject to fluctuations and quarterly variations based upon a variety of factors, many of which are not within our control, including, without limitation:
the volume and severity of health and workers' compensation insurance claims made by our WSEs, recorded as part of our insurance costs, and the timing of related claims information provided by our insurance carriers,
the amount and timing of our insurance premiums and other insurance costs, operating expenses and capital expenditures,
the number of our new clients and the number of WSEs or HRIS Users employed by each new client,
the retention or loss of existing clients, for any reason, including third-party acquisition,
a reduction in the number of WSEs or HRIS Users employed by existing clients,
a reduction in the rate of WSE or HRIS User hiring by existing clients,
the timing of client payments and payment defaults by clients,
the costs associated with our acquisitions of companies, assets and technologies,
any payments or draw downs on our credit facility,
any unanticipated expenses, such as litigation or other dispute-related settlement payments and compliance expenses arising from changes in regulations or regulatory enforcement,
any expenses we incur for geographic and service expansion and service enhancements,
any changes in laws or adverse interpretation or enforcement of laws, which may require us to change the manner in which we operate and/or increase our regulatory compliance costs,
any changes in our effective tax rate,
the issuance of common stock or debt to pay for future acquisitions, which could dilute our stockholders or subject us to significant debt service obligations,

the repurchase of our common stock under our stock repurchase program or otherwise, which could impact earnings per share and increase the ownership percentage of non-participating stockholders,
amortization expense, or the impairment of intangible assets and goodwill, associated with past or future acquisitions, and
the impact of new accounting pronouncements.
In addition, the trading price of our common stock is subject to fluctuation in response to a variety of factors, including the factors above and below, many of which are not within our control, including, without limitation:
the overall performance of the equity markets,
any trading activity, or a market expectation regarding such activity, by our directors, executive officers and significant stockholders,
the economy as a whole, and its impact on SMBs and our clients,
the performance and market perception of companies that investors believe are similar to us,
changes in the interest rates and financial performance of our cash investments, which may increase during periods of high inflation and market volatility and impact our interest income,
any significant changes in the liquidity of our common stock, and
market acceptance of our performance across non-financial factors, including evolving environmental, social, and governance factors favored by investors and required by regulators.
TRINET292021 FORM 10-K


RISK FACTORS

Many of the above factors are discussed in more detail elsewhere in this Risk Factors section and in Part II, Item 7. MD&A, of this Form 10-K. Many of these factors are outside our control, and the variability and unpredictability of these factors have in the past and could in the future cause us to fail to meet our expectations and the expectations of investors and any industry analysts who cover our shares, which could result in a decline in our share price and reduced liquidity in our shares. In addition, the occurrence of one or more of these factors might cause our results of operations to vary widely, which could lead to negative impacts on our margins, short-term liquidity, and our ability to retain or attract key personnel, and could cause other unanticipated issues, including a downgrade of our securities by or change in opinion of industry analysts and a related decline in our share price.
The terms of our credit facility may restrict our current and future operations, which would impair our ability to respond to changes in our business and to manage our business.
Our credit facility contains, and any future indebtedness of ours would likely contain, a number of restrictive covenants that impose significant operating and financial restrictions on us subject to customary exceptions, including restricting our ability to:
incur, assume or prepay debt or incur or assume liens,
pay dividends or distributions or redeem or repurchase capital stock,
make loans, investments or acquisitions,
enter into sale-leaseback transactions,
enter into new lines of business,
complete a significant corporate transaction, such as a merger or sale of our company or its assets, and
enter into agreements that prohibit the incurrence of liens or the payment by our subsidiaries of dividends and distributions.
Our failure to comply with these restrictions and the other terms and conditions under our credit facility could result in a default, which in turn could result in the termination of the lenders’ commitments to extend further credit to us under our credit facility and acceleration of a substantial portion of our indebtedness then outstanding under our credit facility. If that were to happen, we may not be able to repay all of the amounts that would become due under our indebtedness or refinance our debt, which could materially harm our business and force us to seek bankruptcy protection.
Atairos, our largest stockholder, may have significant influence over our Company, and the ownership of capital stock, and thus the voting control, of our Company remains concentrated in our executive officers, directors and their affiliates, which limits your ability to influence corporate matters.

RISK FACTORS

On February 1, 2017, an entity affiliated with Atairos Group, Inc. (together with its affiliates, “Atairos”) became our largest stockholder when it acquired the shares of TriNet common stock previously held by General Atlantic. In connection with this transaction, we appointed Michael J. Angelakis, the Chairman and CEO of Atairos, to our board of directors and agreed to nominate Mr. Angelakis or another designee of Atairos reasonably acceptable to our Nominating and Corporate Governance Committee for election at future annual meetings until Atairos’ beneficial ownership falls below 15% of our common stock. As of January 31, 2022,2024, Atairos beneficially owned approximately 33%36% of our outstanding common stock, and all of our directors, executive officers and their affiliates, including Atairos, beneficially own, in the aggregate, approximately 38%37% of our outstanding common stock. As a result, Atairos, particularly when acting with our executive officers, directors and their affiliates, is able to exert substantial influence on all matters requiring stockholder approval, including the election of directors and approval of significant corporate transactions, such as a merger or other sale of our company or its assets. In addition, our stockholders have no assurances that Atairos’ holdings, or the holdings of our other large stockholders, in our common stock will not increase. This concentration of ownership could limit the ability of other stockholders to influence corporate matters and may have the effect of delaying or preventing a third party from acquiring control over us.

Item 1C. Cybersecurity
Below is a discussion of our risk management and approach to governance as it relates to cyber risks. For additional information on the impact of cyber risks, refer to Part I, Item 1A. Risk Factors, of this Form 10-K, under the heading “Data Privacy and Security Risks”.
Cyber Risk Management and Strategy
Our Global Security program aims to safeguard critical assets through a risk-based approach to cybersecurity. The CSO provides leadership for the program. We employ a defense-in-depth strategy and has established a Security Risk Management Program. In that regard, we built a customized IRCF that was developed with the specific intent of keeping information assets secure and preventing technology resources from unauthorized disclosure, modification, deletion, and destruction. We have modeled our IRCF on several leading industry standards including portions of the NIST Cybersecurity Framework. The IRCF serves as an organizational model for governance and reporting and is reviewed annually.
Our Global Security Organization is responsible for the day-to-day execution of our cyber risk management strategy. This strategy has been incorporated into our overall ERM program and is thus informed by, and overseen through, our ERM program. Our ERM program facilitates identifying, prioritizing, analyzing and remediating enterprise risks, in which cyber risks are included. Within the broader ERM framework, we established a specific program - the IRM program - organizing the governance of risks associated with information held by us. The IRM Steering Committee, of which our CSO is a member, manages the IRM program, discusses the management of cyber risks on a regular cadence and substantive updates from the IRM Steering Committee are provided to the ERM Steering Committee. Finally, through our ERM program, updates and discussion regarding our cybersecurity risk management are provided to and occur at the Risk Committee of our Board of Directors.
To supplement our cyber risk management capabilities, we utilize certain third-party vendors. These vendors support our ability to proactively secure our network and systems, in addition to ongoing monitoring of our cyber environment. With respect to our management of cyber risks arising from third-party vendors, we utilize an internal risk assessment and monitoring program that includes the identification and ongoing review of third-party controls.
As part of our cyber risk management strategy, we established a process for identifying and assessing the material risk of cybersecurity incidents. In the event a cybersecurity incident is identified, the CIRT, which is made up of a cross-functional team, including technology, security, finance and legal professionals, acts in accordance with established processes. The CIRT convenes regular meetings to review and analyze relevant cybersecurity indicators and information. Utilizing an IRC, if it is determined that an incident needs to be reviewed for potential materiality, it is referred to our Chief Legal Officer who will engage the necessary or desirable cross functional professionals as needed in order to make a determination of materiality. We also seek to regularly update and upgrade our technology investments in an effort to further support our ability to identify and assess risks from cybersecurity incidents. We have not identified any cyber threats or incidents that have materially affected or are reasonably likely to materially affect us. For additional information on the potential impact of cybersecurity incidents on our business strategy, operations, or financial condition, refer to Part I, Item 1A. Risk Factors, of this Form 10-K, under the heading “Data Privacy and Security Risks”.
Cyber Risk Governance
Our Cyber Risk Management Strategy described in this Item 1C. is overseen by senior executives with experience in cybersecurity and our business operations and is ultimately overseen by the Risk Committee of the Board. Our Global Security Organization is tasked with executing this strategy through the implementation of cybersecurity policies, procedures, and strategies. In the event that a cybersecurity risk is identified, as and to the extent appropriate, the Global Security Organization manages the day-to-day response to such material risk and provides regular reports to the ERM Steering Committee, or the Risk Committee of the Board, or the Board, as appropriate. The CSO is also an advisor to the Company's Disclosure Committee, which meets quarterly.
On a quarterly basis, a meeting of the Risk Committee is convened to discuss and evaluate our management of enterprise-wide risks. Each meeting of the Risk Committee is facilitated by our Executive Director for ERM and includes programmatic updates from the CSO. The Risk Committee provides updates to the full Board of Directors regarding the state of the Company’s ERM program.
Cyber risks are an enterprise risk that the ERM Program monitors and thus such risks are an ongoing area of focus of the ERM Steering Committee and, as a result, the Risk Committee. On a monthly basis, the ERM Steering Committee is convened and receives pertinent updates regarding our management of cyber risks.
TRINET31 2023 FORM 10-K


PROPERTIES, LEGAL PROCEEDINGS AND MINE SAFETY DISCLOSURES

In addition to the regularly scheduled programmatic updates that are provided to the ERM Steering Committee and the Risk Committee, we also established a process to inform such committees of cybersecurity events and allow them to monitor corresponding remediation efforts. Specifically, the IRM Steering Committee, consisting of senior leaders from the security, privacy, data governance, technology, records management, and third-party risk management programs, reports to the ERM Steering Committee and has the responsibility to provide updates regarding the identification, management, and remediation of significant cybersecurity threats.
The ERM Steering Committee is similarly tasked with providing relevant updates to the Risk Committee regarding cybersecurity threats. Additionally, we have developed a process that is specific to the management and analysis of cybersecurity incidents. This process includes weekly and monthly updates from the CIRT along with escalation criteria that allows for incidents to be reviewed for materiality on an ad hoc basis. These updates are also provided to the ERM Steering Committee and the Risk Committee as necessary.
Our CSO leads our Global Security Organization which is responsible for overseeing the Company's cyber risk management strategy. Our CSO has over 20 years of industry experience, including serving in similar roles leading and overseeing cybersecurity programs at other companies. Team members who support our Global Security team have relevant educational and industry experience, including holding similar positions at other large companies.

Non-GAAP Financial Measures
In addition to financial measures presented in accordance with GAAP, we monitor other non-GAAP financial measures that we use to manage our business, to make planning decisions, to allocate resources and to use as performance measures in our executive compensation plan. These key financial measures provide an additional view of our operational performance over the long-term and provide information that we use to maintain and grow our business.
The presentation of these non-GAAP financial measures is used to enhance the understanding of certain aspects of our financial performance. It is not meant to be considered in isolation from, superior to, or as a substitute for the directly comparable financial measures prepared in accordance with GAAP.

MANAGEMENT'S DISCUSSION AND ANALYSIS

Operating Metrics
Worksite Employees (WSE)
Average WSE growthchange is a volume measure we use to monitor the performance of our PEO business. Our PEO clients generally change their payroll service providers at the beginning of the payroll tax and benefits enrollment year; as a result, we have historically experienced our highest volumes of new PEO clients joining and existing clients terminating in the month of January. PEO client attrition, new PEO client additions and changes in employment levels within our installed PEO client base all impact our Average WSEs and Total WSEs as we move through a calendar year.
We support WSEs from the date on which their co-employment with TriNet commences through the end of their co-employment with TriNet and also after their co-employment period. We define WSEs to include co-employees and other individuals receiving PEO services, such as individuals who receive COBRA benefits post co-employment or are subject to K-1 tax reporting as well as individuals who utilize our PEO platform on behalf of TriNet PEO clients. As part of an ongoing effort to ensure that our billing practices best match the expectations of our customers, in the third quarter of 2023 we determined that certain individuals such as those described above and certain co-employees were not previously or consistently counted in Total WSEs and Average WSEs.] This resulting adjustment increased our reported Total WSEs by approximately 4,500 for December 31, 2023 and Average WSEs by approximately 4,800 and 1,500 for the fourth quarter of 2023 and the full year 2023, respectively. We intend to continue our ongoing effort to ensure that our billing practices best match the expectations of our customers and in the future we may identify additional individuals that should be included in Total WSEs and Average WSEs.
In December 2023, we implemented a platform user access fee to charge clients for those users of our PEO platform that may not be co-employed by us and to charge clients for co-employees for whom payroll may not be regularly run. In addition to co-employees for whom payroll may not be regularly run, this includes individuals authorized by our clients to access and use the PEO platform for functions such as bookkeeping and benefits management. The amount of the fee is comparable to the fee we charge for users of our HRIS platform. While the amount of revenue we recognized in 2023 for this service was not significant, these users of the PEO platform for whose access we charged this fee increased our reported Total WSEs by approximately 12,000 as of December 31, 2023 and Average WSEs by approximately 4,000 and 1,000 for the fourth quarter of 2023 and the full year ended December 31, 2023, respectively.
The effect of this new fee is that we are now receiving revenue from two types of users on our PEO platform, those that are co-employed in our PEO business and those that are utilizing our PEO platform, albeit in a more limited fashion. The table below illustrates how those two components comprise our Total WSE and Average WSE metrics.

In addition to focusing on growing our Average WSE and Total WSE counts, we also focus on pricing strategies, benefit participation and service differentiation to expand the value we provide to our clients and our resulting revenue opportunities. We report the impact of client and WSE participation differences as a change in mix.
We continue to invest in efforts intended to enhance client experience, improve our new sales performance, and manage client attrition, through product development as well as operational and process improvements. As we continue our work in combining our PEO platform and our HRIS SaaS capabilities into a single platform, these various types of TriNet users will all be served from the same platform.

Insurance Cost Ratio (ICR)
ICR is a performance measure calculated as the ratio of insurance costs to insurance service revenues. We believe that ICR promotes an understanding of our insurance cost trends and our ability to align our relative pricing to risk performance.
We purchase workers' compensation and health benefits coverage for our colleagues and WSEs. Under the insurance policies for this coverage, we bear claims costs up to a defined deductible amount. Our insurance costs, which comprise a significant portion of our overall costs, are significantly affected by our WSEs’ health and workers' compensation insurance claims experience. We set our insurance service fees for workers’ compensation and health benefits in advance for fixed benefit periods. As a result, increases in these insurance costs above our projections, reflected as a higher ICR, result in lower net income. Conversely, decreasesDecreases in these insurance costs below our projections, reflected as a lower ICR, result in higher net income.income, but can be an indicator that insurance costs are developing more slowly than our projections, which are reflected in our fees, and this can have a negative impact over time on client retention and new sales.
TRINET39412021 2023 FORM 10-K


MANAGEMENT'S DISCUSSION AND ANALYSIS

Under our fully-insured workers' compensation insurance policies, we assume the risk for losses up to $1 million per claim occurrence (deductible layer). The ultimate cost of the workers’ compensation services provided cannot be known until all the claims are settled. Our ability to predict these costs is limited by unexpected increases in frequency or severity of claims, which can vary due to changes in the cost of treatments or claim settlements.
Under our risk-based health insurance policies, we assume the risk of variability in future health claims costs for our enrollees. This variability typically results from changing trends in the volume, severity and ultimate cost of medical and pharmaceutical claims, due to changes to the components of medicalMCT, which we define as changes in participant use of services, including the introduction of new treatment options, changes in treatment guidelines and mandates, and changes in the mix, cost trend.of providing treatment and timing of services provided to plan participants. These trends change, and other seasonal trends and variability may develop. As a result, it is difficult for us to predict our insurance costs with accuracy and a significant increase in these costs could have a material adverse effect on our business.

ICR was approximately flat when comparing 2023 to 2022 as health insurance costs grew at a faster rate than health ISR, partially offset by favorable workers' compensation prior period claims development.

Total Revenues
Our revenues consist of professional service revenues (PSR)PSR and insurance service revenues (ISR).ISR. PSR represents fees charged to clients for processing payroll-related transactions on behalf of our PEO and HRIS clients, access to our HR expertise, employment and benefit law compliance services, and other HR-related services.and tax credit filing services and fees charged to access our cloud-based HRIS services . ISR consists of insurance-related billings and administrative fees collected from PEO clients and withheld from WSEs for workers' compensation insurance and health benefit insurance plans provided by third-party insurance carriers.
In April 2020, we created our Recovery Credit program to assist in the economic recovery of our existing SMB clients and enhance our ability to retain eligible clients. Eligible clients received one-time reductions against fees for future services, accounted for as a discount, to be received over the following 12 months.
The reduction in total revenue under the Recovery Credit program was estimated each period based on the timing of when eligible clients received the Recovery Credit and the ultimate amount of the total Recovery Credit. As of June 30, 2021, we had fully recognized the maximum amount of $145 million for the Recovery Credit and no further reduction to revenue will be recognized.
In March 2021, we created our 2021 Credit program, which was designed to return up to $25 million to eligible customers based on the performance of our health insurance costs in 2021. We recognized a $25 million reduction to revenue for credits that will be paid to eligible clients under this program. These credits are recorded as a reduction to ISR and are payable within 12 months to eligible clients as of March 31, 2021.
In 2021, we recognized a reduction in revenue of $17 million for the Recovery Credit and $25 million for the 2021 Credit Program, compared to $128 million recognized in 2020 for the Recovery Credit.
Monthly total revenues per Average WSE is a measure we use to monitor the success of our PEO pricing strategies. This measure increased 7%6% in 20212023 compared to 2020.2022.
We also use the following measures to further analyze changes in total revenue:
Volume - the percentage change in period over period co-employed Average WSEs,
Rate - the combined weighted average percentage changes in service fees for each vertical service and changes in service fees associated with each insurance service offering,
Mix - the change in composition of Average WSEs within our verticals combined with the composition of our enrolled WSEs within our insurance service offerings and the composition of products and services our clients receive, including Clarus R+D,
Credit - the weighted average change in amounts recognized for the Recovery Creditour 2022 Credits, and 2021 Credit programs.

Professional Service Revenues
Our PEO and HRIS clients are primarily billed on a fee per WSE or HRIS User per month per transaction. Our vertical approach provides us the flexibility to offer our PEO clients in different industries with varied services at different prices, which we believe potentially reduces the value of solely using Average WSE and Total WSE counts as indicators of future potential revenue performance.

During 2020, stay-at-home orders and social distancing practices due to the COVID-19 pandemic decreased medical services utilization, particularly in the second quarter, as enrollees deferred or cancelled elective procedures and reduced outpatient medical, dental and vision services. Medical services utilization increased in 2021 as enrollees returned to outpatient medical, dental and vision care and elective procedures. The higher utilization was partially offset by reductions in some regions for part of the year due to the surges of the COVID-19 Delta and Omicron variants. As a result, our medical services utilization in 2021 remained below pre-pandemic levels.
The increase in medical services utilization in 2021, combined with increased COVID-19 testing, treatment and vaccinationinsurance costs causedfor the increase in rate.

Liquidity and Capital Resources
Liquidity
Liquidity is a measure of our ability to access sufficient cash flows to meet the short-term and long-term cash requirements of our business operations. Our principal source of liquidity for operations is derived from cash provided by operating activities. We rely on cash provided by operating activities to meet our short-term liquidity requirements, which primarily relate to the payment of corporate payroll and other operating costs, and capital expenditures. Our cash flow related to WSE payroll and benefits is generally matched by advance collection from our PEO clients. To minimize the credit risk associated with remitting the payroll and associated taxes and benefits costs, we require PEO clients to prefund the payroll and related payroll taxes and benefits costs.
We believe that we can meet our present and reasonably foreseeable operating cash needs and future commitments through existing liquid assets and continuing cash flows from corporate operating activities.
Included in our balance sheets are assets and liabilities resulting from transactions directly or indirectly associated with WSEs, including payroll and related taxes and withholdings, our sponsored workers' compensation and health insurance programs, and other benefit programs. Although we are not subject to regulatory restrictions that require us to do so, we distinguish and manage our corporate assets and liabilities separately from those current assets and liabilities held by us to satisfy our employer obligations associated with our WSEs as follows:

PFC is included in current assets as restricted cash, cash equivalents and investments.
We manage our sponsored benefit and workers' compensation insurance obligations by maintaining collateral funds in restricted cash, cash equivalents and investments. These collateral amounts are generally determined at the beginning of each plan year and we may be required by our insurance carriers to adjust our collateral balances when facts and circumstances change. We regularly review our collateral balances with our insurance carriers and anticipate funding further collateral in the future based upon our capital requirements. We classify our restricted cash, cash equivalents and investments as current and noncurrent assets to match against the anticipated timing of payments to carriers.

Investments
We invest a portion of available cash in investment-grade securities with effective maturities less than five years that are classified on our balance sheets as investments. We consider industry and issuer concentrations in our investment policy.
We also invest funds held as collateral to satisfy our long-term obligation towards workers' compensation liabilities. These investments are classified on our balance sheets as restricted cash, cash equivalents and investments. We review the amount and the anticipated holding period of these investments regularly in conjunction with our estimated long-term workers' compensation liabilities and anticipated claims payment trend. At December 31, 2021,2023, our investments had a weighted average duration of less than two years and an average S&P credit rating of AA.

MANAGEMENT'S DISCUSSION AND ANALYSIS

Critical Accounting Judgments and Estimates
Our consolidated financial statements are prepared in accordance with GAAP, which require us to make estimates, judgments, and assumptions that affect reported amounts of assets, liabilities, revenues and expenses, and the related disclosures of contingent assets and liabilities. These estimates are based on historical experience and on various other assumptions that we believe to be reasonable under the circumstances. Some of the assumptions are highly uncertain at the time of estimation. To the extent actual experience differs from the assumptions used, our consolidated financial statements could be materially affected. For additional information about our accounting policies, refer to Note 1 in Part II, Item 8. Financial Statements and Supplementary Data, of this Form 10-K.
The following items require significant estimation or judgment:
Insurance Costs
We purchase workers' compensation and health benefits coverage for our employeescolleagues and WSEs. As part of these insurance policies, we bear claims costs up to a defined deductible amount and as a result, we establish accrued insurance costs including both known claims filed and estimates for incurred but not reported claims.
We use externalqualified actuaries to evaluate, review and recommend estimates of our accrued workers' compensation and health insurance costs. The accrued costs studies performed by these qualified external actuaries analyze historical claims data to develop a range of our potential ultimate costs using loss development, expected loss ratio and frequency/severity methods in accordance with Actuarial Standards of Practice. These methods are applied to classes of the claims data organized by policy year and risk class.
Key judgments and evaluations in arriving at loss estimates by class and the accrued costs selection overall include:
the selection of method used and the relative weights given to selecting the method used for each policy year,
the underlying assumptions of LDF used in these models,
the effect of any changes to the insurers' claims handling and payment processes,
evaluation of medical and indemnity cost trends, costs from changes in the risk exposure being evaluated and any applicable changes in legal, regulatory or judicial environment.
We review and evaluate these judgments and the associated recommendations in concluding the adequacy of accrued costs. Our quarterly reserving process involves the collaboration of our internal qualified external actuaries and our actuarial and finance departments to approve a single point best estimate. In selecting this best estimate, management considers the actuarial estimates and applies informed judgment regarding qualitative factors that may not be fully captured in these actuarial estimates. Such factors include but are not limited to: the timing, of the emergence of claims, volume, severity and complexity of claims, social and judicial trends, andmedical treatment trends, the extent of our historical loss data versus industry information.information, rates of participant turnover, the impact of MCT and seasonal trends, the impact of setting prices in advance of benefit periods, and the impact of unanticipated events. Where adjustments are necessary these are recorded in the period in which the adjustments are identified.
These accrued costs may vary in subsequent quarters from the amount estimated. Certain assumptions used in estimating these accrued costs are highly judgmental. Our accrued costs, results of operations and financial condition can be materially impacted if actual experience differs from the assumptions used in establishing these accrued costs.
Accrued Workers' Compensation Costs
Under our policies, we are responsible for reimbursing the insurance carriers for workers' compensation losses up to $1 million per claim occurrence (Deductible Layer). As workers' compensation costs for a particular period are not known for many years after the losses have occurred, these costs represent our best estimate of unpaid claim
TRINET53 2023 FORM 10-K


MANAGEMENT'S DISCUSSION AND ANALYSIS

losses and loss adjustment expenses within the deductible layerDeductible Layer in accordance with our insurance policies. We use external actuaries to evaluate, review and recommend accrued workers' compensation costs on a quarterly basis. The data is segmented by class and state and analyzed by policy year, and states where we have small exposure are aggregated into a single grouping.
TRINET522021 FORM 10-K


MANAGEMENT'S DISCUSSION AND ANALYSIS

We use a combination of loss development, expected loss ratio and frequency/severity methods which include the following inputs, assumptions and analytical techniques:
Historical volume and severity of workers' compensation cost experience, exposure data and industry loss experience related to TriNet’s insurance policies,
inputs of WSEs’ job responsibilities and location,
estimates of future cost trends,
expected loss ratios for the latest accident year or prior accident years, adjusted for the loss trend, the effect of rate changes and other quantifiable factors, and
LDFs to project the reported losses for each accident year to an ultimate basis.
Final cost settlements may vary materially from the present estimates, particularly when payments do not occur until well into the future. In our experience, plan years related to workers' compensation programs may take 10 years or more to be fully settled.
We believe that our estimate of accrued workers' compensation costs is most sensitive to LDFs given the long reporting and paid development patterns for our workers' compensation loss costs. Our methods of estimating accrued workers' compensation costs rely on these LDFs and an estimate of future cost trend.
The following table illustrates the sensitivity of changes in the LDFs on our year end estimate of insurance costs (in millions of dollars):
Change in loss development factorChange in loss development factorChange in insurance costsChange in loss development factorChange in insurance costs

-2.5%-2.5%($19)-2.5%($18)
+2.5%+2.5%$20+2.5%$19
+5.0%+5.0%$40+5.0%$38
Accrued Health Insurance Costs
We sponsor and administer a number of employee benefit plans for our WSEs, including group health, dental, vision and life insurance as an employer plan sponsor under section 3(5) of the ERISA. Approximately 84%86% of our group health insurance costs relate to risk-based plans in which we agree to reimburse our carriers for any claims paid within an agreed-upon per-person deductible layer up to a maximum aggregate exposure limit per policy. These deductible dollar limits and maximum limits vary by carrier and year.
Costs covered by these insurance plans generally develop on average within three to six months so insurance costs and accrued health insurance costs include estimates of reported losses and claims incurred but not yet paid (IBNP).IBNP. Data is grouped and analyzed by insurance carrier.
To estimate accrued health benefits costs we use a number of inputs, assumptions and analytical techniques:
historical loss claims payment patterns and medical cost trendMCT rates related to TriNet’s insurance policies,
current period claims costs and claims reporting patterns (completion factors), and
plan enrollment.
Medical cost trendMCT rates are a significant factor we use in developing our accrued health insurance costs. Medical cost trendsMCT are developed through an analysis of claims incurred in prior months, provider pricing and indicators of health care utilization, including pharmacy utilization trends, and outpatient and inpatient utilization. Many factors may cause medical cost trendMCT to vary from our estimates. Such factors include, but are not limited to: the timing of the emergence of claims, volume,
TRINET53542021 2023 FORM 10-K


MANAGEMENT'S DISCUSSION AND ANALYSIS

severity and complexity of claims, social and judicial trends, medical treatment trends, the extent of our historical loss data versus industry information, rates of participant turnover, the impact of MCT and seasonal trends, the impact of setting prices in advance of benefit periods, new treatment options, and the impact of unanticipated events.

Completion factors are an actuarial estimate based on historical experience and analysis of current trends, of paid costs to carriers as a percentage of the expected ultimate costs to carriers. Many factors may cause actual claims submissions rates from our carriers to vary from our estimated completion factors, including carrier claims processing patterns, the mix of providers and the mix of electronic versus manual claims submitted to our carriers.

Business Combinations
Under the acquisition method of accounting we generally recognize the identifiable assets acquired and the liabilities assumed in an acquiree at their estimated fair values as of the date of acquisition. We measure goodwill as the excess of the fair value of consideration transferred over the net of the estimated fair values of the identifiable assets acquired and liabilities assumed. Refer to Note 16 in Part II, Item 8, Financial Statements and Supplementary Data, of this Form 10-K .
The acquisition method of accounting requires us to exercise judgment and make significant estimates and assumptions regarding the fair values of the elements of a business combination as of the date of acquisition, including the estimated fair values of identifiable intangible assets, deferred tax asset valuation allowances, liabilities related to uncertain tax positions, and contingencies. This method also allows us to refine these estimates over a one year measurement period to reflect new information obtained about facts and circumstances that existed as of the acquisition date that, if known, would have affected the measurement of the amounts recognized as of that date. If we are required to retroactively adjust provisional amounts that we have recorded for the fair values of assets and liabilities in connection with acquisitions, these adjustments could materially decrease net income and result in lower asset values on our consolidated balance sheets.
These significant estimates are inherently uncertain as they relate to future economic conditions, future cash flows that we expect to generate from the acquired assets and customer behavior. If the subsequent actual results and updated projections of the underlying business activity change compared with the assumptions and projections used to develop these values, we could record impairment charges. In addition, we have estimated the economic lives of certain acquired assets and these lives are used to calculate depreciation and amortization expense. If our estimates of the economic lives change, depreciation or amortization expenses could be accelerated or slowed.

QUANTITATIVE AND QUALITATIVE DISCLOSURES

Item 7A. Quantitative and Qualitative Disclosures About Market Risk
Our exposure to changes in interest rates relates primarily to our investment portfolio. Changes in U.S. interest rates affect the interest earned on the Company's cash, cash equivalents and the fair value of our investments.
Our cash equivalents consist primarily of money market mutual funds, which are not significantly exposed to interest rate risk. Our investments 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 and credit risk by investing in instruments that meet the minimum credit quality, liquidity, diversification and other requirements of our investment policy. Our investments consist of liquid, investment-grade securities. The risk of rate changes on investment balances was not material at December 31, 2023 and 2022.
As of December 31, 2023, we had drawn down $200 million under our floating rate 2021 and 2020.Revolver. The impact of a 100 basis point increase or decrease in market interest rates to interest expense on our 2021 Revolver as of December 31, 2023 over the next twelve months was approximately $2 million.

We have also 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, 2021,2023, based on criteria established in Internal Control - Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission and our report dated February 14, 2022,15, 2024, expressed an unqualified opinion on the Company's internal control over financial reporting.
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.

Accrued Workers’ Compensation and Health Insurance Costs - Refer to Note 1 and Note 76 to the financial statements
Critical Audit Matter Description
The Company offers its clients and worksite employees (WSEs) workers' compensation insurance and health insurance coverage through insurance policies provided by third-party insurance carriers. The Company is obligated to reimburse the insurance carriers for losses up to defined deductible limits, in accordance with the insurance policies. Accrued workers’ compensation and health insurance costs are established to provide for the estimated unpaid costs of reimbursing the carriers.
TRINET57592021 2023 FORM 10-K


FINANCIAL STATEMENTS
The accrued workers’ compensation costs include estimates of unpaid claimfor reported and incurred but not reported losses, accrued costs on reported claims, and loss adjustment expenses.expenses associated with settling the claims. The estimates are based on the Company’s historical and industry loss experience, exposure data, an estimate of future cost trends, expected loss ratios, and loss development factors. Accrued workers' compensation costs, as of December 31, 2021, were $190 million.
The accrued health insurance costs include estimates for reported losses and estimates for claims incurred but not paid. The estimates are based on the Company’s historical claim payment patterns and medical cost trends, current period claim costs and claim reporting patterns, and plan enrollment. Accrued health insurance costs as of December 31, 2021, were $174 million.
Both the accrued workers’ compensation and health insurance costs are established using actuarial methods followed in the insurance industry and the Company uses third-partyqualified actuaries to develop these estimates.
Given the subjectivity of estimating the value of the accrued workers’ compensation and health insurance costs, performing audit procedures to evaluate whether accrued workers’ compensation and health insurance costs recorded for the year ended December 31, 20212023 required a high degree of auditor judgment and an increased extent of effort, including the need to involve our actuarial specialists.
How the Critical Audit Matter Was Addressed in the Audit
Our audit procedures related to the accrued workers’ compensation and health insurance costs included the following, among others:
We tested the effectiveness of controls related to accrued workers’ compensation and health insurance costs.
We tested the underlying data that served as inputs into the actuarial analyses, including testing historical claims and enrollment data and recreating the claim loss triangles.
With the assistance of our actuarial specialists, we evaluated the methods and key assumptions used by management to estimate the accrued workers’ compensation and health insurance costs:
Compared management’s prior-year assumptions of expected development and ultimate loss to actuals incurred during the current year to identify and evaluate potential bias in the determination of the accrued workers’ compensation and health insurance costs.
Developed an independent range of estimates of the accrued costs, utilizing loss development factors and future cost trends for accrued workers’ compensation costs and claim payment patterns and medical trend rates for accrued health insurance costs. We compared our estimated ranges to management’s estimates.

Definition and Limitations of Internal Control over Financial Reporting
A company’s internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. A company’s internal control over financial reporting includes those policies and procedures that (1) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the company; (2) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the company are being made only in accordance with authorizations of management and directors of the company; and (3) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of the company’s assets that could have a material effect on the financial statements.
Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
NOTE 1. DESCRIPTION OF BUSINESS AND SIGNIFICANT ACCOUNTING POLICIES
Description of Business
TriNet Group, Inc. (TriNet, or the Company, we, our and us), a professional employer organization, provides comprehensive human resourcesHCM solutions for small and medium-size businesses under both a co-employmentPEO model and an HRIS services model. These HRHCM solutions include multi-state payroll processing and tax administration, employee benefits programs, including health insurance and retirement plans, workers' compensation insurance and claims management, employment and benefit law compliance, and other HR-related services. Through the co-employment relationship,our PEO service model, we are the employer of record for certain employment-related administrative and regulatory purposes for the worksite employees (WSEs),WSEs, including:
compensation through wages and salaries,
certain employer payroll-related tax payments,
employee payroll-related tax withholdings and payments,
employee benefit programs, including health and life insurance, and others, and
workers' compensation coverage.
Our PEO clients are responsible for the day-to-day job responsibilities of the WSEs.
Through our HRIS services model, we provide cloud-based HCM services to SMBs that allows them to manage hiring, onboarding, employee information, payroll processing, payroll tax administration, health insurance, and other benefits, from a single cloud-based software platform. We are not the co-employer or employer of record for such employees.
We operate in 1one reportable segment. All of our service revenues are generated from external clients. Less than 1% of our revenue is generated outside of the U.S.
Basis of Presentation
Our consolidated financial statements are prepared in conformity with generally accepted accounting principles in the United States of America (GAAP). All intercompany accounts and transactions have been eliminated in consolidation. Certain prior year amounts within operating activities of the Consolidated Statement of Cash Flows have been reclassified to conform to current period presentation. In particular, the amortization of deferred costs, consisting of costs to obtain contracts with customers, cloud computing implementation and debt issuance costs, were previously included in depreciation and amortization and are now separately classified as Amortization of Deferred Costs.
Use of Estimates
The preparation of financial statements in conformity with GAAP requires us to make estimates and assumptions that affect certain reported amounts and related disclosures.
These estimates are based on historical experience and on various other assumptions that we believe to be reasonable from the facts available to us. Some of the assumptions are highly uncertain at the time of estimation. To the extent actual experience differs from the assumptions used, our consolidated financial statements could be materially affected.
Revenue Recognition
Revenues are recognized when the promised services are transferred to our clients, in an amount that reflects the consideration that we expect to receive in exchange for services. We generate all of our revenue from contracts with clients. We disaggregate revenues into professional services revenues and insurance services revenues as reported on the consolidated statements of income and comprehensive income. In the majority of our contracts, both the client and the Company may terminate the contract without penalty by providing a 30-day notice.

FINANCIAL STATEMENTS
Performance Obligations
At contract inception, we assess the services promised in our contracts with clients and identify a performance obligation for each distinct promise to transfer to the client a service or bundle of services. We determined that the following distinct services represent separate performance obligations:
Payroll and payroll tax processing,
Health benefits services,
TRINET642021 FORM 10-K


FINANCIAL STATEMENTS
Workers’ compensation services, and
A right to receive future services at a discount through oura Recovery Credit program.Credit.
Payroll and payroll tax processing performance obligations include services to process payroll and payroll tax-related transactions on behalf of our PEO and HRIS clients. Revenues associated with this performance obligation are reported as professional service revenues and recognized using an output method in which the promised services are transferred when a client's payroll is processed by us and WSEs and users are paid. Professional service revenues are stated net of the gross payroll and payroll tax amounts funded by our clients. Although we assume the responsibilities to process and remit the payroll and payroll related obligations, we do not assume employment-related responsibilities such as determining the amount of the payroll and related payroll obligations. As a result, we are the agent in this arrangement for revenue recognition purposes.
Health benefits and workers' compensation services include performance obligations to provide TriNet-sponsored health benefits and workers' compensation insurance coverage through insurance policies provided by third-party insurance carriers and settle high deductible amounts on those policies. Revenues associated with these performance obligations are reported as insurance services revenues and are recognized using the output method over the period of time that the client and WSEs are covered under TriNet-sponsored insurance policies.
We control the selection of health benefits and workers' compensation coverage made available. As a result, we are the principal in this arrangement for revenue recognition purposes and insurance services revenues are reported gross.
In April 2020,previous years, we created our Recovery Credit programCredits to assist in the economic recovery of our existing SMBPEO clients and enhance our ability to retain these clients. Under this one-time program eligible clients will receive reductions against fees for future services, accounted forThese credits were based on the performance of our insurance costs and were recorded as a discount, over the following 12 months. This optionreduction to renew futureinsurance services at a discount represents a material rightrevenues and is accounted for as a performance obligation (Recovery Credit). This performance obligation will be satisfied when the clients have successfully renewed the services contracts and the future services are transferred. 
The consideration we receive that is allocated to this performance obligation is deferred as an unsatisfied performance obligation and is included in client deposits and other client liabilities on the balance sheet. The amount of consideration we defer each period is dependent on the timing of when eligible clients will receive the Recovery Credit, which is subject to a limit on the total amount of $145 million.
The change in balance for the balance ofliability for credits previously accrued is the Recovery Credit unsatisfied performance obligation was as follows:following:

We generally charge new clients a nominal upfront non-refundable fee to recover our costs to set them up on our TriNet platform for payroll processing and other administrative services, such as benefit enrollments. These fees are accounted for as part of our transaction price and are allocated among the performance obligations based on their relative standalone selling prices.
Client Deposits and Other Client Liabilities
Client deposits and other client liabilities represents our contractual commitments and payables to clients, including indemnity guarantee payments received from clients, amounts prefunded by clients for their payroll and related taxes and other withholding liabilities before payroll is processed or due for payment, as well as service fee consideration received for unsatisfied performance obligations of $23 million.

Variable Consideration and Pricing Allocation
Our contracts with clients generally do not include any variable consideration. However, fromFrom time to time, we may offer credits to our clients considered to be variable consideration. Incentive credits related to contract renewals are recorded as a reduction to revenue as part of the transaction price at contract inception and are allocated among the performance obligations based on their relative standalone selling prices. Credits based on the performance of our insurance costs are recorded as a reduction to insurance services revenues and included in client deposits and other client liabilities on the balance sheet. In 2021, we accrued $25 million under our 2021 Credit Program, payable within 12 months to eligible clients as of March 31, 2021, related to the expected performance of our health insurance costs for the year.
TRINET67 2023 FORM 10-K


FINANCIAL STATEMENTS
We allocate the total transaction price to each performance obligation based on the estimated relative standalone selling prices of the promised services underlying each performance obligation. The transaction price for the payroll and payroll tax processing performance obligations is determined upon establishment of the contract that contains the final terms of the arrangement, including the description and price of each service purchased. The estimated service fee is determined based on observable inputs and includeincludes the following key assumptions: target profit margin, pricing strategies including the mix of services purchased and competitive factors, and client and industry specifics.
The transaction pricefees for access to health benefits insurance and workers' compensation insurance performance obligations is determined during the new client on-boarding and enrollment processes based on the types of benefits coverage the clients and WSEs have elected and the applicable risk profile of the client. We estimate our service fees based on actuarial forecasts of our expected insurance premiums and loss sensitive premium costs and amounts to cover our costs to administer these programs.
We require our clients to prefund payroll and related taxes and other withholding liabilities before payroll is processed or due for payment. Under the provision of our contracts with clients, we generally will process the payment of a client’s payroll only when the client successfully funds the amount required. As a result, there is no financing arrangement for the contracts. However, certain contracts to provide payroll and payroll tax processing services permit the client to pay certain payroll tax components ratably over periods of up to 12 months rather than as payroll tax is otherwise determined and due, which may be considered a significant financing arrangement under FASB ASC Topic 606.606 Revenue from Contracts with Customers. However, as the period between our performing the service under the contract and when the client pays for the service is less than one year, we have elected, as a practical expedient, not to adjust the transaction price.
Unbilled Revenue
WeFor our PEO clients, we recognize WSE payroll and payroll tax liabilities in the period in which the WSEs perform work. When clients' pay periods cross reporting periods, we accrue the portion of the unpaid WSE payroll where we assume, under state regulations, the obligation for the payment of wages and the corresponding payroll tax liabilities associated with the work performed prior to period-end. These estimated payroll and payroll tax liabilities are recorded in accrued wages. The associated receivables, including estimated revenues, offset by advance collections from clients and an allowance for credit losses, are recorded as unbilled revenue. As of December 31, 20212023 and 2020,2022, advance collections included in unbilled revenue were $8 million and $24$9 million, respectively.
TRINET662021 FORM 10-K


FINANCIAL STATEMENTS
Contract Costs
We recognize as deferred commission expense the incremental cost to obtain a contract with a client for certain components under our commission plans for sales representatives and channel partners that are directly related to new clients onboarded as we expect to recover these costs through future service fees. Such assets are amortized over the estimated average client tenure. These commissions are earned on the basis of the revenue generated from payroll and payroll tax processing performance obligations. When the commission on a renewal contract is not commensurate with the commission on the initial contract, any incremental commission will be capitalized and amortized over the estimated average client tenure. If the commission for both the initial contract and renewal contracts are commensurate, such commissions are expensed in the contract period. The below table summarizes the amounts capitalized and amortized during the years ended December 31, 2021, 20202023, 2022 and 2019:2021:

Certain commission plans pay a commission on estimated professional service revenues over the first 12 months of the contract with clients. The portion of commission paid in excess of the actual commission earned in that period is recorded as prepaid commission. When the prepaid commission is considered earned, it is classified as a deferred commission expense and subject to amortization. We dodid not have material contract liabilities as of December 31, 20212023 and 2020.2022.
TRINET68 2023 FORM 10-K


FINANCIAL STATEMENTS
Insurance Costs
Our insurance plans are provided by third-party insurance carriers under risk-based or guaranteed-cost insurance policies. Under risk-based policies, we agree to reimburse our carriers for any claims paid within an agreed-upon per-person deductible layer up to a maximum aggregate exposure limit per policy. These deductible dollar limits and maximum limits vary by carrier and year. Under guaranteed-cost policies, our carriers establish the premiums and we are not responsible for any deductible.
Insurance costs include insurance premiums for coverage provided by insurance carriers, paymentsexpenses for claimclaims costs and other risk management and administrative services, reimbursement of claims payments made by insurance carriers or third-party administrators below a predefined deductible limit, and changes in accrued costs related to contractual obligations with our workers' compensation and health benefit carriers.
At policy inception, annual workers' compensation premiums are estimated by the insurance carriers based on projected wages over the duration of the policy period and the risk categories of the WSEs. We initially pay premiums based on these estimates. As actual wages are realized, premium expense recorded may differ from estimated premium expense, creating an asset or liability throughout the policy year. Such asset or liability is reported on our consolidated balance sheets as prepaid expenses or insurance premiums and other payables, respectively.
Accrued Workers' Compensation Costs
We have secured workers' compensation insurance policies with insurance carriers to administer and pay claims for our clients and WSEs. We are responsible for reimbursing the insurance carriers for losses up to $1 million per claim occurrence (deductible layer). Insurance carriers are responsible for administering and paying claims. We are responsible for reimbursing each carrier up to a deductible limit per occurrence. Accrued workers' compensation costs represent our liability to reimburse insurance carriers for our share of their losses and loss adjustment expenses. These accrued costs are established to provide for the estimated ultimate costs of paying claims within the deductible layer in accordance with workers' compensation insurance policies. These accrued costs include estimates for reported and incurred but not reported (IBNR) losses, accrued costs on reported claims, and expenses associated with processing and settling the claims. In establishing these accrued costs, we use an external actuary to provide an estimate of undiscounted future cash payments that would be made to settle the claims based upon:
TRINET672021 FORM 10-K


FINANCIAL STATEMENTS
historical loss experience, exposure data, and industry loss experience related to TriNet’s insurance policies,
inputs including WSE job responsibilities and location,
historical volume and severity of workers' compensation claims,
an estimate of future cost trends,
expected loss ratios for the latest accident year or prior accident years, adjusted for the loss trend, the effect of rate changes and other quantifiable factors, and
loss development factors to project the reported losses for each accident year to an ultimate basis.
We assess the accrued workers' compensation costs on a quarterly basis. For each reporting period, changes in the actuarial methods and assumptions resulting from changes in actual claims experience and other trends are incorporated into the accrued workers' compensation costs. Adjustments to previously established accrued costs estimates are reflected in the results of operations for the period in which the adjustment is identified. Such adjustments could be significant, reflecting any variety of new adverse or favorable trends. Accordingly, final claim settlements may vary materially from the present estimates, particularly when those payments may not occur until well into the future. In our experience, plan years related to workers' compensation programs may take ten years or more to be settled.
We do not discount accrued workers' compensation costs. Costs expected to be paid within one year are recorded as accrued workers' compensation costs. Costs expected to be paid beyond one year are included in accrued workers' compensation costs, less current portion.

FINANCIAL STATEMENTS
We have collateral agreements with various insurance carriers where either we retain custody of funds in trust accounts which we record as restricted cash and cash equivalents, or remit funds to carriers. Collateral whether held by us, or the carriers, is used to settle our insurance and claim deductible obligations to them. Collateral requirements are established at the policy year and are re-assessed by each carrier annually. Based on the results of each assessment, additional collateral may be required for or paid to the carrier or collateral funds may be released or returned to the Company. In instances where we pay collateral to carriers and the agreement permits net settlement of obligations against collateral held, we record our accrued costs net of that collateral (Carrier Collateral Offset). We offset Carrier Collateral Offset against our obligation due within the next 12 months before applying against long-term obligations. Collateral balances in excess of accrued costs are recorded in other assets.
Accrued Health Insurance Costs
We sponsor and administer a number of employee benefit plans for our PEO WSEs, including group health, dental, and vision as an employer plan sponsor under section 3(5) of the ERISA. In 2021,2023, the majority of our group health insurance costs related to risk-based plans. Our remaining group health insurance costs were for guaranteed-cost policies.
Accrued health insurance costs are established to provide for the estimated unpaid costs of reimbursing the carriers for paying claims within the deductible layer in accordance with risk-based health insurance policies. These accrued costs include estimates for reported losses, plus estimates for claims incurred but not paid. We assess accrued health insurance costs regularly based upon external actuarial studies that include other relevant factors such as current and historical claims payment patterns, plan enrollment and medical trend rates.
In certain carrier contracts we are required to prepay our obligations for the expected claims activity for subsequent periods. These prepaid balances by agreement permit net settlement of obligations and offset the accrued health insurance costs. As of December 31, 20212023 and 2020,2022, prepayments and miscellaneous receivables offsetting accrued health insurance costs were $54$58 million and $49$57 million, respectively. When the prepaid amount is in excess of our recorded liability the net asset position is included in prepaid expenses. As of December 31, 20212023 and 2020,2022, accrued health insurance costs offsetting prepaid expenses were $79$68 million and $58$73 million, respectively.

FINANCIAL STATEMENTS
Leases
We determine if a new contractual arrangement is a lease at contract inception. If a contract contains a lease, we evaluate whether it should be classified as an operating or a finance lease. If applicable as a lease, we record our lease liabilities and right-of-use (ROU) assets based on the future minimum lease payments over the lease term and only include options to renew a lease in the future minimum lease payments if it is reasonably certain that we will exercise that option. For certain leases with original terms of twelve months or less we recognize the lease expense as incurred and we do not recognize lease liabilities and ROU assets.
We measure our lease liabilities based on the future minimum lease payments discounted over the lease term. We determine our discount rate at lease inception using our incremental borrowing rate, which is based on our outstanding term debts that are collateralized by certain corporate assets. As of December 31, 20212023 and 2020,2022, the weighted-average rate used in discounting the lease liability was 3.9%4.2% and 4.0%3.9%, respectively.
We measure our ROU assets based on the associated lease liabilities adjusted for any lease incentives such as tenant improvement allowances and classify operating ROU assets in other assets in our consolidated balance sheets. For operating leases, we recognize expense for lease payments on a straight-line basis over the lease term.
Cash and Cash Equivalents
Cash and cash equivalents include bank deposits and short-term, highly liquid investments. Investments with original maturity dates of three months or less are considered cash equivalents.
Restricted Cash, Cash Equivalents and Investments
Restricted cash, cash equivalents and investments presented on our consolidated balance sheets include:
cash and cash equivalents in trust accounts functioning as security deposits for our insurance carriers,
payroll funds collected representing cash collected in advance from clients which we designate as restricted for the purpose of funding WSE payroll and payroll taxes and other payroll related liabilities, and
TRINET70 2023 FORM 10-K


FINANCIAL STATEMENTS
amounts held in trust for current and future premium and claim obligations with our insurance carriers, which amounts are held in trust according to the terms of the relevant insurance policies and by the local insurance regulations of the jurisdictions in which the policies are in force.
Investments
Our marketable investments are primarily classified as available-for-sale and are carried at estimated fair value.
Unrealized gains and losses are reported as a component of accumulated other comprehensive income, net of deferred income taxes. The amortized cost of debt investments is adjusted for amortization of premiums and accretion of discounts from the date of purchase to the earliest call date for premiums or the maturity date for discounts. 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 to determine realized gains and losses on the sale of available-for-sale securities. Realized gains and losses are included in interest incomeexpense, bank fees, and other in the accompanying consolidated statements of income and comprehensive income.
We assess our investments for credit impairment. We review several factors to determine whether an unrealized loss is credit related, such as financial condition and future prospects of the issuer. To the extent that a security's amortized cost basis exceeds the present value of the cash flows expected to be collected from the security, an allowance for credit losses will be recognized. If management intends to sell or will more likely than not be required to sell the security before any anticipated recovery, a write down will be recognized in earnings measured as the entire difference between the amortized cost and the then-current fair value.
We have investments within our unrestricted and our restricted accounts. Unrestricted investments are recorded on the balance sheet as current or noncurrent based upon the remaining time to maturity, and investments subject to restrictions are classified as current or noncurrent based on the expected payout of the related liability.
TRINET692021 FORM 10-K


FINANCIAL STATEMENTS
Comprehensive Income
Comprehensive income consists of net income and other comprehensive income. Other comprehensive (loss) income includes those gains and losses included in comprehensive income, but excluded from net income, in accordance with GAAP. Other comprehensive (loss) income is primarily comprised of immaterial net unrealized gains or losses arising on available-for-sale investments, net of deferred taxes.
Fair Value of Financial Instruments
Fair value is an exit price, representing the amount that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. As such, fair value is a market-based measurement that should be determined based on assumptions that market participants would use in pricing an asset or a liability.
Our financial assets recorded at fair value on a recurring basis are comprised of cash equivalents, available-for-sale marketable securities and certificates of deposits. We measure certain financial assets at fair value for disclosure purposes, as well as on a nonrecurring basis when they are deemed to be other-than-temporarily impaired. Our other current financial assets and liabilities have fair values that approximate their carrying value due to their short-term nature.
Assets and liabilities recorded at fair value are measured and classified in accordance with a three-tier fair value hierarchy based on the observability of the inputs available in the market to measure fair value, summarized as follows:
Level 1—observable inputs for identical assets or liabilities, such as quoted prices in active markets,
Level 2—inputs other than the quoted prices in active markets that are observable either directly or indirectly,
Level 3—unobservable inputs in which there is little or no market data, which requires that we develop our own assumptions.
The fair value hierarchy requires us to maximize the use of observable inputs and minimize the use of unobservable inputs when measuring fair value. We classify our cash equivalents, investments and long-term debt in the fair value hierarchy based on the lowest level input that is significant to the fair value measurement in its entirety.

FINANCIAL STATEMENTS
Accounts Receivable
Our accounts receivable represents outstanding gross billings to clients, net of an allowance for estimated credit losses. We require our clients to prefund payroll and related liabilities before payroll is processed or due for payment. If a client fails to fund payroll or misses the funding cut-off, at our sole discretion, we may pay the payroll and the resulting amounts due to us are recognized as accounts receivable. When client payment is received in advance of our performance under the contract, such amount is recorded as client deposits. We establish an allowance for credit losses based on the credit quality of clients, current economic conditions, the age of the accounts receivable balances, historical experience, and other factors that may affect clients’ ability to pay, and charge-off amounts against the allowance when they are deemed uncollectible. The allowance was immaterial at December 31, 20212023 and 2020.2022.
Property Equipment and SoftwareEquipment
We record property and equipment at historical cost and compute depreciation using the straight-line method over the estimated useful lives of the assets or the lease terms, generally three years to five years for software and office equipment, five years to seven years for office equipment, furniture and fixtures, and the shorter of the asset life or the remaining lease term for leasehold improvements. We expense the cost of maintenance and repairs as incurred and capitalize leasehold improvements.
We capitalize internal and external costs incurred to develop internal-use computer software during the application development stage. Application development stage costs include software configuration, coding, and installation. Capitalized costs are amortized on a straight-line basis over the estimated useful life, typically ranging from three years to five years, commencing when the software is placed into service. We expense costs incurred during the preliminary project stage, as well as general and administrative, overhead, maintenance and training costs, and costs that do not add functionality to existing systems.
TRINET702021 FORM 10-K


FINANCIAL STATEMENTS
We periodically assess the likelihood of unsuccessful completion of projects in progress, as well as monitor events or changes in circumstances, which might suggest that impairment has occurred, and recoverability should be evaluated. An impairment loss is recognized if the carrying amount of the asset is not recoverable and exceeds the future net cash flows expected to be generated by the asset.
We evaluate our long-lived assets for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset or asset group may not be recoverable. An asset is considered impaired if the carrying amount exceeds the undiscounted future net cash flows the asset is expected to generate. An impairment charge is recognized for the amount by which the carrying amount of the assets exceeds its fair value. Assets to be disposed of are reported at the lower of the carrying amount or fair value, less selling costs.
Goodwill, Software and Other Intangible Assets
Our goodwill and identifiable intangible assets with indefinite useful lives are not amortized but are tested for impairment on an annual basis or when an event occurs or circumstances change in a way to indicate that there has been a potential decline in the fair value of the reporting unit. Goodwill impairment is determined by comparing the estimated fair value of the reporting unit to its carrying amount, including goodwill. All goodwill is associated with 1one reporting unit within our 1one reportable segment.
Annually, we perform a qualitative assessment to determine whether it is more likely than not that the fair value of the reporting unit has declined below its carrying value. This assessment considers various financial, macroeconomic, industry, and reporting unit specific qualitative factors. We perform our annual impairment testing in the fourth quarter. Based on the results of our reviews, no impairment loss was recognized in the results of operations for the years ended December 31, 2021, 20202023, 2022 and 2019.2021.
Intangible assets and software with finite useful lives are amortized over their respective estimated useful lives ranging from one year to ten years using either the straight-line method or an accelerated method. Intangible assets are reviewed for indicators of impairment at least annually and evaluated for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable.

Advertising Costs
We expense the costs of producing advertisements at the time production occurs, and expense the cost of running advertisements in the period in which the advertising space or airtime is used as sales and marketing expense. Advertising costs were $21$37 million, $19$29 million, and $18$21 million for the years ended December 31, 2021, 20202023, 2022 and 2019,2021, respectively.
Stock Based Compensation
Our stock basedstock-based awards to employees include time based and performance based restricted stock units and restricted stock awards, stock options and an employee stock purchase plan. Compensation expense associated with restricted stock units and restricted stock awards is based on the fair value of common stock on the date of grant. Compensation expense associated with stock options and employee stock purchase plan are based on the estimated grant date fair value method using the Black-Scholes option pricing model. Expense is recognized using a straight-line amortization method over the respective vesting period for awards that are ultimately expected to vest, with adjustments to expense recognized in the period in which forfeitures occur.
Income Taxes
We account for our provision for income taxes using the asset and liability method, under which we recognize income taxes payable or refundable for current year and deferred tax assets and liabilities for the future tax effect of events that have been recognized in either our financial statements or tax returns. We measure our current and deferred tax assets and liabilities based on provision of enacted tax laws of those jurisdictions in which we operate. The effect of changes in tax laws and regulations, or interpretations, is recognized in our consolidated financial statements in the period that includes the enactment date.

FINANCIAL STATEMENTS
We recognize deferred tax assets and liabilities based on temporary differences between the carrying amounts of assets and liabilities for financial reporting purposes and amounts used for income tax purposes, as well as the expected benefits of using net operating loss and other carryforwards. We are required to establish a valuation allowance when it is determined more likely than not that the deferred tax assets will not be realized. Provision for income taxes may change when estimates used in determining valuation allowances change or when receipt of new information indicates the need for adjustment in valuation allowances. Changes in valuation allowances are reflected as a component of the provision for income taxes in the period the change is enacted.of adjustment.
We recognize a reserve for uncertain tax positions taken or expected to be taken in a tax return when it is concluded that tax positions are not more likely than not to be sustained upon examination by taxing authorities, including resolution of any related appeals or litigation processes, based on the technical merits of the positions. Assumptions, judgment and the use of estimates are required in determining if the more likely than not standard has been met when developing the provision for income taxes and in determining the expected benefit. The tax benefits of the position recognized in the financial statements are then measured based on the largest amount of benefit that is greater than 50% likely to be realized upon settlement with a taxing authority. Unrecognized tax benefits due to tax uncertainties that do not meet the minimum probability threshold are included as other liabilities and are charged to earnings in the period that such determination is made. We recognize interest and penalties related to uncertain tax positions as a component of income tax expense. Accrued interest and penalties are included in other non-current liabilities on the consolidated balance sheet.sheets.
Concentrations of Credit Risk
Financial instruments subject to concentrations of credit risk include cash, cash equivalents and investments (unrestricted and restricted), accounts receivable, and amounts due from insurance carriers. We maintain these financial assets principally in domestic financial institutions. We perform periodic evaluations of the relative credit standing of these institutions. Our exposure to credit risk in the event of default by the financial institutions holding these funds is limited to amounts currently held by the institution in excess of insured amounts.
Under the terms of professional services agreements, clients agree to maintain sufficient funds or other satisfactory credit at all times to cover the cost of their current payroll, all accrued paid time off, vacation or sick leave balances, and other vested wage and benefit obligations for all their work site employees. We generally require payment from our clients on or before the applicable payroll date.

The inputs and assumptions for the pricing models are market observable inputs including trades of comparable securities, dealer quotes, credit spreads, yield curves and other market-related data.

We have not adjusted the prices obtained from the independent pricing service and we believe the prices received from the independent pricing service are representative of the prices that would be received to sell the assets at the measurement date (exit price).

FINANCIAL STATEMENTS
Incurred claims related to prior years represent changes in estimates for ultimate losses on workers' compensation claims. For the years ended December 31, 2021, 20202023, 2022 and 2019,2021, the favorable development is due to lower than expected reported claim frequency and severity for the more recent years.
As of December 31, 20212023 and 2020,2022, we had $43$32 million and $45$43 million respectively, of collateral held by insurance carriers of which $8$5 million for both periodsand $7 million, respectively, was offset against accrued workers' compensation costs as the agreements permit and are net settled of insurance obligations against collateral held.
NOTE 8.7. LEASES
Our leasing activities predominantly consist of leasing office space that we occupy, which we have classified as operating leases. Our leases are comprised of fixed payments with remaining lease terms of 1 to 7 years, 1 of which includes an option to extend for up to 56 years. As of December 31, 2021,2023, we have not included any options to extend or cancel in the calculation of our lease liability or ROU asset. We do not have any significant residual value guarantees or restrictive covenants in our leases.
We recognized operating lease expense of $13$11 million, $17$15 million and $19$13 million for the years ended December 31, 2023, 2022 and 2021, 2020respectively. For the years ended December 31, 2023 and 2019, respectively.2022, we recognized $6 million and $20 million, respectively, of lease impairment due to the closing of several offices.

In February 2021, concurrently with the closing of the 2029 Notes offering, we entered into a new $500 million revolving facility (our 2021 Revolver) under a new credit agreement (our 2021 Credit Agreement) and our 2018 Credit Agreement was terminated. Letters of credit issued pursuant to the revolving facility reduce the amount available for borrowing under the 2021 Revolver. As
In August 2023, concurrently with the issuance of December 31,the 2031 Notes, we amended certain provisions of our credit agreement, dated February 26, 2021, we had remainingas amended, to, among other things (1) increasing the aggregate capacity of $491 million under our 2021 Revolver.Revolver from $500 million to $700 million and (2) extending the maturity date of our 2021 Revolver to August 16, 2028.
The annual interest rate for borrowings under our 2021 Revolver iswas previously calculated based on an applicable London Interbank Offered Rate (LIBOR)LIBOR tenor of our choosing, plus a margin of 1.25% to 2.00%, or, at our option, the alternative base rate (ABR), plus a margin of 0.25% to 1.00%. In the second quarter of 2023, we replaced the interest rate based on LIBOR and related LIBOR-based mechanics with an interest rate based on the forward-looking Secured Overnight Financing Rate (Term SOFR). Term SOFR loans will be charged interest at the Term SOFR rate (subject to a 0.00% floor), plus a margin between 1.25% and 2.00%, depending on the Company’s total net leverage ratio, plus a credit adjustment spread of 10 basis points for all tenors (such Term SOFR rate plus the credit adjustment spread, the "Adjusted Term SOFR Rate"). The applicable LIBORTerm SOFR or ABR margin is based on our Total Leverage Ratio, as defined in the 2021 Credit Agreement. The ABR is the highest of (a) the applicable Federal Reserve Bank of New York rate in effect on such day (which rate is the greater of the Federal funds Effective Rate in effect on such day and the Overnight Bank Funding Rate in effect on such day), as defined in our 2021 Credit Agreement plus 0.50% (b) the prime rate in effect on such day, and (c) the Adjusted Term SOFR Rate for a one month interest period, as published by two U.S. Government Securities Business Days prior to such day daily plus 1.00%.

The indenture governing our 2029 Notes and 2031 Notes each includes restrictive covenants limiting our ability to: (i) create liens on certain assets to secure debt; (ii) grant a subsidiary guarantee of certain debt without also providing a guarantee of the 2029 Notes;Notes or 2031 Notes, as applicable; and (iii) consolidate or merge with or into, or sell or otherwise dispose of all or substantially all of our assets to, another person, subject, in each case, to certain customary exceptions.
The 2021 Credit Agreement includes negative covenants that limit our ability to incur indebtedness and liens, sell assets and make restricted payments, including dividends and investments, subject to certain exceptions. In addition, the 2021 Credit Agreement also contains other customary affirmative and negative covenants and customary events of default. The 2021 Credit Agreement also contains a financial covenant that requires the Company to maintain certain maximum total net leverage ratios. We were in compliance with all financial covenants under the 2021 Credit Agreement, 2029 Notes and 2031 Notes at December 31, 2021.2023.
NOTE 10.9. COMMITMENTS AND CONTINGENCIES
Contingencies
On September 29, 2020, a class action was filed in the United States District Court for the Middle District of Florida against the directors of certain TriNet subsidiaries and other TriNet employees on behalf of a putative class of participants in 2two retirement plans available to TriNet’s eligible worksite employees, the TriNet 401(k) Plan and the TriNet Select 401(k) Plan. The complaint is similar to claims recently brought against a number of employers including PEOs and generally alleges that the defendants violated certain fiduciary obligations to Plan participants under the Employee Retirement Income Security Act of 1974 with respect to overseeing plan investment and recordkeeping fees. At this time, we are unableOn October 21, 2022, the court issued an order declining to reasonably estimate any possible loss, or range of loss,certify a class with respect to this matter. We believeclaims against the TriNet 401(k) Plan, but certified a class with respect to claims are without merit.against the TriNet Select 401(k) Plan. On April 26, 2023, the court entered an order granting TriNet's motion for summary judgment on all remaining claims. No appeal was timely filed and the matter is closed.
We are and, from time to time, have been and may in the future become involved in various litigation matters, legal proceedings, and claims arising in the ordinary course of our business, including disputes with our clients or various class action, collective action, representative action, and other proceedings arising from the nature of our co-employment relationship with our clients and WSEs in which we are named as a defendant. In addition, due to the nature of our co-employment relationship with our clients and WSEs, we could be subject to liability for federal and state law violations, even if we do not participate in such violations. While our agreements with our clients contain indemnification provisions related to the conduct of our clients, we may not be able to avail ourselves of such provisions in every instance. We have accrued our current best estimates of probable losses with respect to these matters, which are individually and in aggregate immaterial to our consolidated financial statements.
While the outcome of the matters described above cannot be predicted with certainty, management currently does not believe that any such claims or proceedings will have a materially adverse effect on our consolidated financial position, results of operations, or cash flows. However, the unfavorable resolution of any particular matter or our reassessment of our exposure for any of the above matters based on additional information obtained in the future could have a material impact on our consolidated financial position, results of operations, or cash flows.
NOTE 11.10. STOCK BASED COMPENSATION
Equity Based Incentive Plans

Management’s Report on Internal Control Over Financial Reporting
We are responsible for establishing and maintaining adequate internal control over financial reporting as defined in Rules 13a-15(f) and 15d-15(f) promulgated under the Exchange Act to provide reasonable assurance regarding the reliability of financial reporting and the preparation of the financial statements for external purposes in accordance with GAAP.
Due to inherent limitations, internal control over financial reporting is not intended to provide absolute assurance that a misstatement of our financial statements would be prevented or detected. 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 policies or procedures may deteriorate.
We have performed an assessment of the effectiveness of our internal control over financial reporting as of December 31, 20212023 based upon criteria set forth in Internal Control - Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission.
Based on this assessment, we determined that our internal control over financial reporting was effective as of December 31, 2021.2023.
Deloitte & Touche LLP, our independent registered public accounting firm, has issued an audit report on the effectiveness of our internal control over financial reporting as of December 31, 2021.2023. This audit report appears in Part II, Item 8. Financial Statements and Supplementary Data, of this Form 10-K.

There were no changes in our internal control over financial reporting that occurred during the three months ended December 31, 20212023 that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.
