We continued to achieve quarter-over-quarter revenue growth, reflecting our rate increases, higher Average WSEs and the $51 million decrease in the Recovery Credit recognized in 2021.
During the second quarter of 2021, our Average WSEs increased 6% and total WSEs increased 9%, primarily as a result of continued hiring in our installed base.
Medical services utilization continued to approach more typical levels in the second quarter of 2021, resulting in higher insurance costs compared to the same period in 2020, when stay-at-home orders and social distancing practices due to the COVID-19 pandemic caused a decrease in the medical services utilization.
In the second quarter of 2021, increases in insurance costs and operating expenses resulted in quarter-over-quarter decreases in our net income and Adjusted Net Income of (28)% and (24)%, respectively.

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. In subsequent filings, we will no longer provide Net Service Revenues, Net Insurance Service Revenues and Net Insurance Margin. Our consolidated statements of income and comprehensive income will continue to disclose total revenues, insurance service revenues and insurance cost, determined in accordance with GAAP, which are the key components of these non-GAAP measures.

Non-GAAP Measure | Definition | How We Use The Measure
Net Service Revenues | • Sum of professional service revenues and Net Insurance Service Revenues, or total revenues less insurance costs. | • Provides a comparable basis of revenues on a net basis. Professional service revenues are presented net of client payroll costs whereas insurance service revenues are presented gross of insurance costs for financial reporting purposes. • Acts as the basis to allocate resources to different functions and evaluates the effectiveness of our business strategies by each business function. • Provides a measure, among others, used in the determination of incentive compensation for management.
Net Insurance Service Revenues | • Insurance service revenues less insurance costs. | • Is a component of Net Service Revenues. • Provides a comparable basis of revenues on a net basis. Professional service revenues are presented net of client payroll costs whereas insurance service revenues are presented gross of insurance costs for financial reporting purposes. Promotes an understanding of our insurance services business by evaluating insurance service revenues net of our WSE related costs which are substantially pass-through for the benefit of our WSEs. Under GAAP, insurance service revenues and costs are recorded gross as we have latitude in establishing the price, service and supplier specifications.
Net Insurance Margin | • Net Insurance Margin is the ratio of Net Insurance Services Revenues to insurance service revenues. | • Provides a comparable basis of Net Insurance Service Revenues relative to insurance service revenues. Promotes an understanding of our pricing to risk performance.

Adjusted EBITDA | • Net income, excluding the effects of: - income tax provision, - interest expense, bank fees and other, - depreciation, - amortization of intangible assets, and - stock based compensation expense. | • Provides period-to-period comparisons on a consistent basis and an understanding as to how our management evaluates the effectiveness of our business strategies by excluding certain non-cash charges such as depreciation and amortization, and stock-based compensation recognized based on the estimated fair values. We believe these charges are either not directly resulting from our core operations or not indicative of our ongoing operations. • Enhances comparisons to prior periods and, accordingly, facilitates the development of future projections and earnings growth prospects. • Provides a measure, among others, used in the determination of incentive compensation for management. • We also sometimes refer to Adjusted EBITDA margin, which is the ratio of Adjusted EBITDA to total revenues.
Adjusted Net Income | • Net income, excluding the effects of: - effective income tax rate (1), - stock based compensation, - amortization of intangible assets, - non-cash interest expense (2), and - the income tax effect (at our effective tax rate (1) of these pre-tax adjustments. | • Provides information to our stockholders and board of directors to understand how our management evaluates our business, to monitor and evaluate our operating results, and analyze profitability of our ongoing operations and trends on a consistent basis by excluding certain non-cash charges.
Corporate Operating Cash Flows | • Net cash provided by (used in) operating activities, excluding the effects of: - Assets associated with WSEs (accounts receivable, unbilled revenue, prepaid expenses and other current assets) and - Liabilities associated with WSEs (client deposits and other client liabilities, accrued wages, payroll tax liabilities and other payroll withholdings, accrued health benefit costs, accrued workers' compensation costs, insurance premiums and other payables, and other current liabilities). | • Provides information that our stockholders and management can use to evaluate our cash flows from operations independent of the current assets and liabilities associated with our WSEs. • Enhances comparisons to prior periods and, accordingly, used as a liquidity measure to manage liquidity between corporate and WSE related activities, and to help determine and plan our cash flow and capital strategies.

Operating Metrics
Worksite Employees (WSE)
Average WSE growth is a volume measure we use to monitor the performance of our business. Average WSEs increased 6% when comparing the second quarter of 2021 to the same period in 2020, primarily due to increased hiring in our installed base across all verticals, led by our Technology vertical. Our Recovery Credit program was designed to assist in the economic recovery of SMBs and to promote client loyalty and incentivize client retention. In the second quarter and first half of 2021, most of the hiring in our installed based was from clients that benefited from this program.
Total WSEs can be used to estimate our beginning WSEs for the next period and, as a result, can be used as an indicator of our potential future success in growing our business and retaining clients.
Anticipated revenues for future periods can diverge from the revenue expectation derived from Average WSEs or Total WSEs due to pricing differences across our HR solutions and services and the degree to which clients and WSEs elect to participate in our solutions during future periods. 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 our revenue opportunities. We report the impact of client and WSE participation differences as a change in mix.
In addition to focusing on retaining and growing our WSE base, we continue to review acquisition opportunities that would add appropriately to our scale. We continue to invest in efforts intended to enhance client experiences and manage attrition, through operational and process improvements.

MANAGEMENT'S DISCUSSION AND ANALYSIS | Table of Contents

Total Revenues
Our revenues consist of professional service revenues (PSR) and insurance service revenues (ISR). PSR represents fees charged to clients for processing payroll-related transactions on behalf of our clients, access to our HR expertise, employment and benefit law compliance services, and other HR-related services. ISR consists of insurance-related billings and administrative fees collected from 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 these clients. Eligible clients will receive one-time reductions against fees for future services, accounted for as a discount, to be received over the following 12 months. We recognized a reduction in total revenues of $5 million in the second quarter of 2021 for the Recovery Credit, compared to a reduction of $56 million recognized in the second quarter of 2020.
The reduction in revenue is estimated each period based on the timing of when eligible clients will receive the Recovery Credit and the ultimate amount of the total Recovery Credit. As of June 30, 2021, we have fully recognized the $145 million maximum amount for the Recovery Credit and no further reduction to revenue will be recognized.
We recognized a $25 million reduction to revenue under our 2021 Credit Program in the first quarter of 2021. This amount reflects estimated credits that will be paid to eligible clients under this program, based on the expected performance of our health insurance costs in 2021, and is currently limited to $25 million. These credits are recorded as a reduction to ISR and are payable within 12 months to eligible clients as of March 31, 2021. To the extent we experience higher than expected health insurance costs during the remainder of 2021, this estimate may be reduced. There was no change in this estimate in the second quarter.
Monthly total revenues per Average WSE is a measure we use to monitor the success of our pricing strategies. This measure increased 9% during the second quarter of 2021 compared to the same period in 2020.
We also use the following measures to further analyze changes in total revenue:
•Volume - the percentage change in period over period 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
•Credit - the weighted average amounts recognized for the Recovery Credit and 2021 Credit programs.

|  | PSR |  |
|  | ISR - % represents proportion of ISR to total revenues |

MANAGEMENT'S DISCUSSION AND ANALYSIS | Table of Contents

The growth in total revenues for the quarter was primarily driven by higher Average WSEs and growth in rate, combined with the $51 million decrease in the Recovery Credit recognized in 2021. The growth in total revenues for the first half of 2021 was primarily driven by higher Average WSEs and growth in rate, combined with the $39 million decrease in the Recovery Credit recognized in 2021. This was partially offset by the $25 million reduction in revenue recognized for the 2021 Credit Program in the first quarter of 2021.

MANAGEMENT'S DISCUSSION AND ANALYSIS | Table of Contents

Operating Income
Our operating income consists of total revenues less insurance costs and OE. Our insurance costs include insurance premiums for coverage provided by insurance carriers, reimbursement of claims payments made by insurance carriers or third-party administrators, and changes in accrued costs related to contractual obligations with our workers' compensation and health benefit carriers. Our OE consists primarily of our corporate employees' compensation related expenses, which includes payroll, payroll taxes, SBC, bonuses, commissions and other payroll-and benefits-related costs.
The table below provides a view of the changes in components of operating income for the second quarter and first half of 2021, as compared to the same periods in 2020.

(in millions) |
$173 |  | Second Quarter 2020 Operating Income
| +152 |  |  | Higher total revenues primarily driven by higher Average WSEs, rate increases and the $51 million decrease in the Recovery Credit recognized.
| -185 |  |  | Higher insurance costs primarily as a result of more typical medical services utilization, compared to the prior year period, which had lower than typical medical services utilization due to stay-at-home orders and social distancing practices due to the COVID-19 pandemic.
| -19 |  |  | Higher OE primarily as a result of increased payroll tax compliance costs and D&A, together with higher compensation and consulting expenses to support initiatives to improve client experience, enhance service offerings, and improve processes.
$121 |  | Second Quarter 2021 Operating Income

(in millions) |
$293 |  | YTD 2020 Operating Income

| -171 |  |  | Higher insurance costs primarily as a result of more typical medical services utilization, compared to the prior year period, which had lower than typical medical services utilization due to stay-at-home orders and social distancing practices due to the COVID-19 pandemic.
| -27 |  |  | Higher OE primarily as a result of increased payroll tax compliance costs, technology services and D&A, together with higher compensation and consulting expenses to support initiatives to improve client experience, enhance service offerings, and improve processes.
$259 |  | YTD 2021 Operating Income

MANAGEMENT'S DISCUSSION AND ANALYSIS | Table of Contents

Professional Service Revenues
Our clients are billed on a fee per WSE per month per transaction. Our vertical approach provides us the flexibility to offer our 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.
We also analyze changes in PSR with the following measures:
•Volume - the percentage change in period over period Average WSEs,
•Rate - the weighted average percentage change in fees for each vertical,
•Mix - the change in composition of Average WSEs across our verticals, and
•Recovery Credit - the weighted average amounts recognized for the Recovery Credit program.
The growth in PSR for the quarter was driven by higher Average WSEs, a growth in rate and the decrease in the Recovery Credit recognized. The growth in rate was attributed to increased payroll activity and price increases, weighted to our smaller customers. We continued to experience a favorable change in our vertical mix of WSEs, as a return to hiring in certain industries was partially offset by attrition in other industries. The growth in PSR for the first half of 2021 was primarily driven by rate growth, favorable mix changes and the decrease in the Recovery Credit recognized.

17

MANAGEMENT'S DISCUSSION AND ANALYSIS | Table of Contents

Insurance Service Revenues
ISR consists of insurance services-related billings and administrative fees collected from clients and withheld from WSE payroll for health benefits and workers' compensation insurance provided by third-party insurance carriers.
We use the following measures to analyze changes in ISR:
•Volume - the percentage change in period over period Average WSEs,
•Rate - the weighted average percentage change in fees associated with each of our insurance service offerings,
•Mix - all other changes including the composition of our enrolled WSEs within our insurance service offerings (health plan enrollment), and
•Credit - the weighted average amounts recognized for the Recovery Credit and 2021 Credit programs.
The growth in ISR for the quarter and first half of 2021 was primarily driven by higher Average WSEs, rate increases and the decrease in the Recovery Credit recognized. The growth in the first half of 2021 was partially offset by the $25 million reduction in revenue recognized in the first quarter for the 2021 Credit Program.

18

MANAGEMENT'S DISCUSSION AND ANALYSIS | Table of Contents

Insurance Costs
Insurance costs include insurance premiums for coverage provided by insurance carriers, payments for claims costs and other risk management 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.
We use the following measures to analyze changes in insurance costs:
•Volume - the percentage change in period over period Average WSEs,
•Rate - the weighted average percentage change in cost trend associated with each of our insurance service offerings, and
•Mix - all other changes including the composition of our enrolled WSEs within our insurance service offerings (health plan enrollment).
During the second quarter and first half of 2020, stay-at-home orders and social distancing practices due to the COVID-19 pandemic decreased the medical services utilization as enrollees deferred or cancelled elective procedures and reduced outpatient medical, dental and vision services. Medical services utilization continued to approach more typical levels in the second quarter and first half of 2021, though we 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.
The increase in medical services utilization in 2021, combined with COVID-19 testing, treatment and vaccination costs, caused the increase in rate in the second quarter and first half of 2021. This was partially offset by larger positive claims development as our accrued health costs as of March 31, 2021 and December 31, 2020 were paid during the first half of 2021.
We believe that the ratio of insurance costs to insurance services revenue promotes an understanding of our insurance cost trends and our ability to align our relative pricing to risk performance. The ratio of insurance costs to insurance service revenues increased to 85% for the second quarter of 2021, compared to 74% for the same period

19

MANAGEMENT'S DISCUSSION AND ANALYSIS | Table of Contents

in 2020. For the first half of 2021, the ratio of insurance costs to insurance service revenues increased to 84% compared to 80% for the first half of 2020. The higher ratio for both the second quarter and first half of 2021 was due to the increase in rate for insurance costs, resulting from higher medical services utilization, exceeding the increase in rate for ISR.
Operating Expenses
OE includes cost of providing services (COPS), sales and marketing (S&M), general and administrative (G&A), systems development and programming (SD&P), and depreciation and amortization expenses (D&A).
We had approximately 2,700 corporate employees as of June 30, 2021 in 15 offices across the U.S. Our corporate employees' compensation-related expenses represent a majority of our operating expenses. Compensation costs for our corporate employees include payroll, payroll taxes, SBC, bonuses, commissions and other payroll- and benefits-related costs. Compensation-related expense represented 61% and 67% of our OE in the second quarters of 2021 and 2020 and 63% and 65% in the first half of 2021 and 2020, respectively.
During the second quarter and the first half of 2021, we experienced OE increases of 12% and 8%, respectively, when compared to the same periods in 2020. During the second quarter and the first half of 2021, the percent of OE to total revenues was 16%, consistent with the same periods in 2020.

MANAGEMENT'S DISCUSSION AND ANALYSIS | Table of Contents

Other Income (Expense)
Other income (expense) consists primarily of interest and dividend income from investments, interest expense under our previous credit facility and interest on our 3.50% Senior Notes due 2029 (our 2029 Notes) issued in February 2021.
Interest income decreased primarily due to lower average market interest rates. Interest expense, bank fees and other increased due to the higher interest rate on our 2029 Notes and costs incurred in the first quarter due to the early repayment and termination of our floating rate debt.
Income Taxes
Our effective tax rate (ETR) was 22% and 26% for the second quarter of 2021 and 2020, respectively, and 24% and 26% for the first half of 2021 and 2020, respectively. The decrease when comparing the quarter and year to date rates for 2021 with the same periods in 2020 was primarily due to benefits associated with a favorable adjustment of our previously disputed receivable from the IRS and an increase in tax benefits related to stock-based compensation.

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. We believe that we have sufficient liquidity and capital resources to satisfy future requirements and meet our obligations to our clients, creditors and debt holders.
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:

| June 30, 2021 |  | December 31, 2020

Current assets: |  |  |  |  |  |  |

Other current assets | 80 |  | 451 |  | 531 |  |  | 59 |  | 355 |  | 414 |
Total current assets | $ | 690 |  | $ | 1,394 |  | $ | 2,084 |  |  | $ | 432 |  | $ | 1,728 |  | $ | 2,160 |

Working capital | $ | 554 |  | $ | — |  | $ | 554 |  |  | $ | 290 |  | $ | — |  | $ | 290 |

Working capital for WSEs related activities
We designate funds to ensure that we have adequate current assets to satisfy our current obligations associated with WSEs, the Recovery Credit liability and 2021 Credit Program liability. We expect the Recovery Credit and 2021 Credit Program aggregate liability of $88 million as of June 30, 2021 to be settled over the following 12 months. We manage our WSE payroll and benefits obligations through collections of payments from our clients which generally occurs two to three days in advance of client payroll dates. We regularly review our short-term obligations associated with our WSEs (such as payroll and related taxes, insurance premium and claim payments) and designate funds required to fulfill these short-term obligations, which we refer to as PFC. 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.
Working capital for corporate purposes
Corporate working capital as of June 30, 2021 increased $264 million from December 31, 2020, primarily driven by a $163 million increase in corporate unrestricted cash and cash equivalents and a $74 million increase in corporate investments.
We use our available cash and cash equivalents to satisfy our operational and regulatory requirements and to fund capital expenditures. We believe that we can meet our present and reasonably foreseeable operating cash needs and future commitments through existing liquid assets, continuing cash flows from corporate operating activities and the potential issuance of debt or equity securities. We believe our existing corporate cash and cash equivalents and positive working capital will be sufficient to meet our working capital expenditure needs for at least the next twelve months.

Operating Activities
Components of net cash provided by operating activities are as follows:

| Six Months Ended June 30,
(in millions) | 2021 | 2020
Net cash used in operating activities | $ | (190) |  | $ | (130) |
Net cash used in operating activities - WSE | (430) |  | $ | (445) |
Net cash provided by operating activities - Corporate | 240 |  | 315 |

The year-over-year change in net cash used in operating activities for WSE purposes was primarily driven by timing of client payments, payments of payroll and payroll taxes, settlement of the Recovery Credit, and insurance claim activities. We expect the changes in restricted cash and cash equivalents to correspond to WSE cash provided by (or used in) operations as we manage our obligations associated with WSEs through restricted cash.
Our corporate operating cash flows in the first half of 2021 decreased, when compared to the same period in 2020, due to the decrease in our net income and the timing of our payments of corporate obligations.

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 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 June 30, 2021, our investments had a weighted average duration of less than two years and an average S&P credit rating of AA.
As of June 30, 2021, we held approximately $1.9 billion in restricted and unrestricted cash, cash equivalents and investments, of which $464 million was unrestricted cash and cash equivalents and $325 million was unrestricted investments. Refer to Note 2 in the condensed consolidated financial statements and related notes included in this Form 10-Q.
Capital Expenditures
During the first half of 2021 and 2020, we continued to make investments in software and hardware and we enhanced our existing service offerings and technology platform. We expect capital investments in our software and hardware to continue in the future.

Financing Activities
Net cash provided by financing activities in the first half of June 30, 2021 and 2020 consisted of our debt and equity-related activities.

| Six Months Ended June 30,
(in millions) | 2021 | 2020

Repayment of borrowings | (370) |  | (11) |
Cash provided by financing activities | $ | 43 |  | $ | 122 |

During the first half of June 30, 2021, we repurchased 925,251 shares of our common stock for approximately $74 million through our stock repurchase program. As of June 30, 2021, approximately $284 million remained available for repurchase under all authorizations by our board of directors. We plan to use current cash and cash generated from ongoing operating activities to fund this stock repurchase program.
In February 2021, we issued $500 million aggregate principal amount of our 2029 Notes. $370 million of the proceeds was used to repay and terminate the 2018 Term Loan A. The remaining funds will be used for general corporate purposes. Refer to Note 6 in the condensed consolidated financial statements and related notes included in this Form 10-Q for further information.
In February 2021, concurrently with the closing of the 2029 Notes offering, we entered into a new $500 million revolving credit facility under a new credit agreement (our 2021 Credit Agreement). The 2021 Credit Agreement includes a $100 million letter of credit sub-facility and a $40 million swingline sub-facility. We also have the option to incur incremental credit facilities of up to the greater of $450 million and 100% of EBITDA for the most recent period of four fiscal quarters for which financial statements have been delivered. Such incremental facilities are subject to obtaining additional commitments from lenders.
Capital Resources
Sources of Funds
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 clients. To minimize the credit risk associated with remitting the payroll and associated taxes and benefits costs, we require 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.
Covenants
The Indenture governing the 2029 Notes 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; 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 our 2021 Credit Agreement at June 30, 2021.
Critical Accounting Policies, Estimates and Judgments
There have been no material changes to our critical accounting policies as discussed in our 2020 Form 10-K.

QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK AND CONTROLS AND PROCEDURES | Table of Contents

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 June 30, 2021 and December 31, 2020.

QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK AND CONTROLS AND PROCEDURES | Table of Contents

Controls and Procedures
Evaluation of Disclosure Controls and Procedures
We have, with the participation of our Chief Executive Officer (CEO) and our Chief Financial Officer (CFO), evaluated the effectiveness of our disclosure controls and procedures as of June 30, 2021, as defined in Rules 13a-15(e) and 15d-15(e) under the Securities Exchange Act of 1934, as amended, or the Exchange Act.
Based on the evaluation of our disclosure controls and procedures as of June 30, 2021, our CEO and CFO have concluded that the Company’s disclosure controls and procedures were effective as of such date in ensuring that (i) information required to be disclosed by the Company in reports that it files or submits under the Exchange Act is accumulated and communicated to the Company’s management, including the CEO and CFO, to allow timely decisions regarding required disclosure and (ii) such information is recorded, processed, summarized and reported within the time periods specified in the SEC rules and forms.
We have concluded that the condensed consolidated financial statements included in this Quarterly Report on Form 10-Q fairly present, in all material respects, our financial position, results of operations and cash flows for the periods presented in conformity with GAAP.
Changes in Internal Control Over Financial Reporting
There were no changes in our internal control over financial reporting identified in connection with the evaluation required by Rule 13a-15(d) and 15d-15(d) of the Exchange Act that occurred during the quarter ended June 30, 2021, that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.
Limitations on Effectiveness of Controls and Procedures
In designing and evaluating the disclosure controls and procedures, management recognizes that any controls and procedures, no matter how well designed and operated, can provide only reasonable assurance of achieving the desired control objectives. In addition, the design of disclosure controls and procedures must reflect the fact that there are resource constraints and that management is required to apply judgment in evaluating the benefits of possible controls and procedures relative to their costs.

(Unaudited)
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 resources solutions for small and medium-size businesses under a co-employment model. These HR 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, we are the employer of record for certain employment-related administrative and regulatory purposes for the worksite employees (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 clients are responsible for the day-to-day job responsibilities of the WSEs.
We operate in one 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
These unaudited condensed consolidated financial statements and accompanying notes have been prepared in accordance with accounting principles generally accepted in the United States of America for interim financial reporting and the instructions to Form 10-Q and Rule 10-01 of Regulation S-X of the Rules and Regulations of the Securities and Exchange Commission. Certain information and note disclosures included in our annual financial statements prepared in accordance with GAAP have been condensed or omitted pursuant to such rules and regulations. In the opinion of management, the condensed consolidated financial statements reflect all adjustments, that are normal and recurring in nature, necessary for fair financial statement presentation. The results of operations for the three and six months ended June 30, 2021 are not necessarily indicative of the operating results anticipated for the full year. These financial statements should be read in conjunction with the audited Consolidated Financial Statements included in Part II, Item 8. Financial Statements and Supplementary Data of our Annual Report on Form 10-K for the year ended December 31, 2020 (2020 Form 10-K).
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.

FINANCIAL STATEMENTS | Table of Contents

Revenue Recognition
Performance Obligations
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 these clients. Under this one-time program eligible clients will receive reductions against fees for future services, accounted for as a discount, over the following 12 months. This option to renew future services at a discount represents a material right 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 the balance of the Recovery Credit unsatisfied performance obligation was as follows:

| June 30, 2021
(in millions) | Three Months Ended | Six Months Ended
Balance at beginning of period | $ | 77 |  | $ | 92 |
(+) Accruals | 5 |  | 17 |
(-) Distributions to clients | (19) |  | (46) |
Balance at end of period | $ | 63 |  | $ | 63 |

Variable Consideration and Pricing Allocation
Our contracts with clients generally do not include any variable consideration. However, from 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 the six months ended June 30, 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.
Accrued Health Insurance Costs
We sponsor and administer a number of employee benefit plans, including group health, dental, and vision as an employer plan sponsor under section 3(5) of the ERISA. In the six months ended June 30, 2021, a 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 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 June 30, 2021 and December 31, 2020, prepayments and miscellaneous receivables offsetting accrued health insurance costs were $54 million and $49 million, respectively. When the prepaid amount is in excess of our recorded liability the net asset position is included in prepaid expenses. As of June 30, 2021 and December 31, 2020, accrued health insurance costs offsetting prepaid expenses were $69 million and $58 million, respectively.

NOTE 2. CASH, CASH EQUIVALENTS AND INVESTMENTS - UNRESTRICTED AND RESTRICTED
Under the terms of the agreements with certain of our workers' compensation and health benefit insurance carriers, we are required to maintain collateral in trust accounts for the benefit of specified insurance carriers and to reimburse the carriers’ claim payments within our deductible layer. We invest a portion of the collateral amounts in marketable securities. We report the current and noncurrent portions of these trust accounts as restricted cash, cash equivalents and investments on the consolidated balance sheets.
We require our clients to prefund their payroll and related taxes and other withholding liabilities before payroll is processed or due for payment. This prefund is included in restricted cash, cash equivalents and investments as payroll funds collected, which is designated to pay pending payrolls, payroll tax liabilities and other payroll withholdings.
We also invest available corporate funds, primarily in fixed income securities which meet the requirements of our corporate investment policy and are classified as available for sale (AFS).
Our total cash, cash equivalents and investments are summarized below:

FINANCIAL STATEMENTS | Table of Contents

Gross unrealized losses were immaterial at June 30, 2021 and December 31, 2020.
Unrealized losses on fixed income securities are principally caused by changes in interest rates and the financial condition of the issuer. In analyzing an issuer's financial condition, we consider whether the securities are issued by the federal government or its agencies, whether downgrades by credit rating agencies have occurred, and industry analysts' reports. As we have the ability to hold these investments until maturity, or for the foreseeable future, no decline was deemed to be other-than-temporary. Actual maturities may differ from contractual maturities because borrowers may have the right to prepay obligations with or without prepayment penalties.
The fair value of debt investments by contractual maturity are shown below:

(in millions) |  | June 30, 2021 |
One year or less |  | $ | 188 |  |
Over one year through five years |  | 340 |  |

The gross proceeds from sales and maturities of AFS securities for the three and six months ended June 30, 2021 and June 30, 2020 are presented below. We had immaterial gross realized gains and losses from sales of investments for the three and six months ended June 30, 2021 and 2020.

NOTE 4. FINANCIAL INSTRUMENTS AND FAIR VALUE MEASUREMENTS
Fair Value of Financial Instruments
We use an independent pricing source to determine the fair value of our securities. The independent pricing source utilizes various pricing models for each asset class, including the market approach. 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).
The carrying value of the Company's cash equivalents and restricted cash equivalents approximate their fair values due to their short-term maturities.
We did not have any Level 3 financial instruments recognized in our balance sheet as of June 30, 2021 and December 31, 2020. There were no transfers between levels as of June 30, 2021 and December 31, 2020.
Fair Value Measurements on a Recurring Basis
The following tables summarize our financial instruments by significant categories and fair value measurement on a recurring basis as of June 30, 2021 and December 31, 2020.

FINANCIAL STATEMENTS | Table of Contents

Fair Value of Financial Instruments Disclosure
Long-Term Debt
As of December 31, 2020, our long-term debt was floating rate debt and the fair value approximated its carrying value (exclusive of issuance costs). The fair value of our floating rate debt was estimated based on a discounted cash flow, which incorporated credit spreads and market interest rates to estimate the fair value and was considered Level 3 in the hierarchy for fair value measurement.
The fair value of our 2029 Notes was obtained from a third-party pricing service and is based on observable market inputs. As such, the fair value of the senior notes is considered Level 2 in the hierarchy for fair value measurement. As of June 30, 2021, our 2029 Notes were carried at their cost, net of issuance costs, and had a fair value of $495 million.
Derivative Instruments
As of December 31, 2020, the fair value of the interest rate collar derivative, included in accounts payable and other current liabilities, was $1 million and was classified as Level 2 in the fair value hierarchy. In conjunction with the repayment and termination of our 2018 Term Loan, the interest rate collar derivative was terminated and settled and a realized loss of $1 million was recognized in net income for the six months ended June 30, 2021.
NOTE 5. ACCRUED WORKERS' COMPENSATION COSTS
The following table summarizes the accrued workers’ compensation cost activity for the three and six months ended June 30, 2021 and 2020:

Total accrued costs, net of carrier collateral offset | $ | 190 |  | $ | 197 |
Payable in less than 1 year (net of collateral paid to carriers of $3 at June 30, 2021 and December 31, 2020, respectively) | $ | 57 |  | $ | 59 |
Payable in more than 1 year (net of collateral paid to carriers of $5 at June 30, 2021 and December 31, 2020, respectively) | 133 |  | 138 |
Total accrued costs, net of carrier collateral offset | $ | 190 |  | $ | 197 |

Incurred claims related to prior years represent changes in estimates for ultimate losses on workers' compensation claims. For the three and six months ended June 30, 2021, the change was primarily due to lower than expected claim frequency.

FINANCIAL STATEMENTS | Table of Contents

As of June 30, 2021 and December 31, 2020, we had $44 million and $45 million, respectively, of collateral held by insurance carriers of which $8 million for both periods was offset against accrued workers' compensation costs as the agreements permit and are net settled of insurance obligations against collateral held.
NOTE 6. LONG-TERM DEBT AND REVOLVING CREDIT AGREEMENTS
As of June 30, 2021 and December 31, 2020, our long-term debt consisted of the following:

(in millions) | June 30, 2021 | December 31, 2020
2018 Term Loan A | $ | — |  | $ | 370 |
2029 Notes | 500 |  | — |
Principal amount | 500 |  | 370 |
Deferred issuance costs | (5) |  | — |
Less: current portion | — |  | (22) |
Long-term debt, noncurrent | $ | 495 |  | $ | 348 |
Annual contractual interest rate | 3.50 | % | 1.77 | %
Effective interest rate | 3.67 | % | 1.87 | %

In June 2018 we entered into a $425 million term loan A (our 2018 Term Loan) under our 2018 credit agreement (our 2018 Credit Agreement). The 2018 Credit Agreement included a $250 million revolving credit facility (our 2018 Revolver). The 2018 Credit Agreement was terminated in February 2021.
In February 2021, we issued $500 million aggregate principal of 3.50% senior unsecured notes maturing in March 2029 (our 2029 Notes). The 2029 Notes are a senior unsecured obligation of TriNet Group, Inc. and rank equally with all of its existing and future senior unsecured indebtedness. Interest payments on the 2029 Notes are due semi-annually in arrears on March 1 and September 1, beginning on September 1, 2021. The net proceeds were used to repay and terminate our 2018 Term Loan and for general corporate purposes.
We may voluntarily redeem the 2029 Notes, in whole or in part, 1) at any time prior to March 1, 2024 at (a) 100% of their principal amount, plus a “make whole” premium or (b) with the net cash proceeds received from an equity offering at a redemption price equal to 103.50% of the principal amount, provided the aggregate principal amount of all such redemptions does not exceed 40% of the original aggregate principal amount of the 2029 Notes; 2) at any time on or after March 1, 2024 at a prepayment price equal to 101.75% of the principal amount; 3) at any time on or after March 1, 2025 at a prepayment price equal to 100.875%of the principal amount; and 4) at any time on or after March 1, 2026 at a prepayment price equal to 100% of the principal amount; in each case, plus accrued and unpaid interest, if any, to but excluding, the date of redemption.
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 the 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 of June 30, 2021, we had remaining capacity of $491 million under our 2021 Revolver.
The annual interest rate for borrowings under our 2021 Revolver is calculated based on an applicable London Interbank Offered Rate (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%. The applicable LIBOR 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, as defined in our 2021 Credit Agreement plus 0.50% (b) the prime rate, and (c) one month LIBOR adjusted daily plus 1.00%.
In the event TriNet Group, Inc. receives a Corporate Issuer Credit Rating that is one level below investment grade rating or higher from at least two Nationally Recognized Statistical Rating Organizations, then rating based pricing applies and, for so long as rating based pricing applies, irrespective of the Total Leverage Ratio, the LIBOR margin will be 1.125% and the ABR margin will be 0.125%.

FINANCIAL STATEMENTS | Table of Contents

The indenture governing our 2029 Notes 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; 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 at June 30, 2021.
NOTE 7. 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 participants in two 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. These claims are in the early stages, and we are unable to reasonably estimate any possible loss, or range of loss, with respect to this matter. We believe the claims are without merit.
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 8. STOCK BASED COMPENSATION
Restricted Stock Units (RSUs) and Restricted Stock Awards (RSAs)
Time-based RSUs and RSAs generally vest over a four-year term. Performance-based RSUs and RSAs are subject to vesting requirements and are earned, in part, based on certain financial performance metrics as defined in the grant notice. Actual number of shares earned may range from 0% to 200% of the target award. Performance-based awards granted in 2021 and 2020 are earned based on a single-year performance period subject to subsequent multi-year time-based vesting with 50% of the shares earned vesting in one year after the performance period and the remaining shares in the year after. RSUs and RSAs are generally forfeited if the participant terminates service prior to vesting.

Stock Repurchases
During the six months ended June 30, 2021, we repurchased 925,251 shares of common stock for approximately $74 million. We retire shares in the period they are acquired and account for the payment as a reduction to stockholders' equity. As of June 30, 2021, approximately $284 million remained available for further repurchases of our common stock under all authorizations from our board of directors under this program. This repurchase authorization has no expiration.
NOTE 10. INCOME TAXES
Our effective tax rate (ETR) was 22% and 26% for the three months ended June 30, 2021 and 2020, respectively, and 24% and 26% for the six months ended June 30, 2021 and 2020, respectively. The decrease when comparing the quarter and year to date rates for 2021 with the same periods in 2020 was primarily due to benefits associated with a favorable adjustment of our previously disputed receivable from the IRS and an increase in tax benefits related to stock-based compensation.
During the six months ended June 30, 2021, there was a decrease of $1 million in our unrecognized tax benefits. The total amount of gross interest and penalties accrued was immaterial. It is reasonably possible the amount of the unrecognized benefit could increase or decrease within the next 12 months for which an estimate of the impact on net income cannot be made.
We are subject to tax in U.S. federal and various state and local jurisdictions, as well as Canada. We are open to federal and significant state income tax examinations for tax years 2016 and subsequent years.
We previously paid Notices of Proposed Assessments disallowing employment tax credits totaling $11 million, plus interest of $4 million in connection with the IRS examination of Gevity HR, Inc. and its subsidiaries, which was acquired by TriNet in June 2009. TriNet filed suit in June 2016 to recover the disallowed credits, and the issue is being resolved through the litigation process. TriNet and the U.S. filed cross motions for summary judgment in federal district court. On September 17, 2018, the district court granted our motion for summary judgment and denied the U.S.'s motion. On January 18, 2019, the district court entered judgment in favor of TriNet in the amount of $15 million, plus interest. The U.S. filed a notice of appeal of the federal district court's decision on March 18, 2019. The U.S. filed its opening brief in the court of appeals on June 10, 2019 and we filed our answering brief on July 24, 2019 to which the government filed its reply brief on September 6, 2019. Oral arguments occurred on March 11, 2020. On November 5, 2020, the court of appeals affirmed the district court’s judgement in favor of TriNet. The April 5, 2021 deadline for the IRS to petition the Supreme Court for review passed without a petition. TriNet will pursue recovery of the judgment.

Risk Factors
Other than the restated risk factors below, which have been updated to reflect recent events, there have been no material changes in our risk factors disclosed in Part 1, Item 1A, of our 2020 Form 10-K.
If we are not recognized as an employer of worksite employees under federal and state regulations, we and our clients could be adversely impacted.
In order to sponsor our employee benefit plan offerings for WSEs, we must qualify as an employer of WSEs for certain purposes under the Code and ERISA. In addition, our status as the employer for the purposes of ERISA is important for purposes of ERISA’s preemption of certain state laws. The definition of employer under various laws is not uniform, and under both the Code and ERISA the term is defined in part by different facts and circumstances tests.
Generally, these tests are designed to evaluate whether an individual is an independent contractor or employee and they provide 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 in evaluating these issues 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 employer of WSEs for the purposes of Sections 3(5) and 3(40) of ERISA and that our health and welfare plans are single-employer plans that, as such, are entitled to ERISA’s preemption 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, the DOL routinely audits employee benefit plan offerings of employers, and these audits can take years to complete. In one routine audit of TriNet’s plans, 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. 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 of 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 and welfare plans are single-employer plans entitled to ERISA’s preemption of applicable state laws. While we have no current DOL audit on-going regarding this issue, the DOL’s position remains uncertain, and this issue 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 and welfare plans sponsored by PEOs are multiple-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 health and welfare employee benefits to WSEs. Any such adjustment would require significant investment in time, cost and management attention and would have a material impact on our clients and WSEs, 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. 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. Moreover, the IRS' 401(k) guidance and qualification requirements are not applicable to the operation of our cafeteria plans.
If we are not recognized as an employer under the Code, we may be required to change the method by which we report and remit payroll taxes to the tax authorities. Such changes could have a material adverse effect on our business and results of operations.
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, employee and independent contractor classifications, employee benefit, health and retirement plan laws, workers' compensation laws, employment and payroll tax laws, worksite

OTHER INFORMATION | Table of Contents

safety laws, insurance and banking laws, wage and hour laws, anti-discrimination laws, and many laws 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.
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,
•require us to make significant changes to how we do business and provide services,
•affect the extent and type of employee benefits that employers and co-employers can or must provide employees,
•alter the amount, timing and type of taxes employers, co-employers, clients and WSEs are required to pay and that we must manage for and collect from our clients,
•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, and/or
•mandate new compliance requirements, disclosures or services.
Any of these changes could have a material adverse effect on our financial condition and results of operations.
The laws that apply in our industry and to employers and co-employers have in the past, and could in the future, be changed, replaced or interpreted in a manner adverse to our operations and we are not able to predict the occurrence, direction or ultimate impact of these events.
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/or 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 many rely on client income tax returns (which PEOs do not process in their role as the co-employer) and/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 often subject to broad agency interpretation. In addition, the processes used to evaluate payroll tax filings are designed with individual taxpayers, not PEOs that aggregate the filings of many clients, in mind, which can lead to agency confusion and make it difficult to predict agency interpretations.
Examples of these programs include the 2015 PATH Act, which allows SMBs to use research and development tax credits submitted on the SMB’s income tax return to reduce payroll taxes, and the CARES Act and FFCRA Act payroll tax credit and payroll tax deferral programs enacted in 2020 and 2021, which allow SMBs to defer certain payroll tax obligations to a later date or to receive payroll tax reductions and refunds based on SMB employment practices that are beyond a PEO’s control. We have experienced, and expect to continue to experience, the IRS taking positions that PEOs, rather than clients, are responsible for client errors under these and similar programs, and that tax benefits should be calculated on an aggregate PEO, rather than individual client, basis, which can limit our ability to obtain full tax benefits for our clients under these and similar programs and/or increase our exposure to credit risk if we are not able to recover excess benefits paid to our clients. We cannot predict how these positions will ultimately be resolved.
These developments, and any other new laws, changes in laws or adverse application or interpretation of laws, including payroll tax incentive programs, could reduce or eliminate the attractiveness of our services and our ability to support 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, require us to make substantial changes to the way in which we operate, or require us to pay client liabilities with no guarantee of subsequent recovery from our clients, and any one of these outcomes could result in a material adverse effect on our financial condition and results of operations.
