MANAGEMENT'S DISCUSSION AND ANALYSIS

Management’s Discussion and Analysis of Financial Condition and Results of Operations

Executive Summary

Overview

We are a leading provider of human resources (HR) solutions for small to midsize businesses (SMBs). Under our co-employment model, we assume many of the complex and burdensome responsibilities of being an employer, helping our clients minimize employer-related risks and manage administrative and compliance responsibilities associated with employment.

We deliver a comprehensive suite of products and services which allow our clients and their worksite employees (WSEs) to administer and manage HR-related functions, including compensation and benefits, payroll and other transactional HR needs, employee data, and health insurance and workers' compensation programs, using our technology platform and HR expertise.

We operate in one reportable segment. Less than 1% of revenue is generated outside of the U.S.

Technology Platform

Our technology platform provides our clients and WSEs online and mobile tools to store, view and manage core HR information and administer a variety of HR transactions, such as payroll processing, tax administration, employee onboarding and termination, compensation reporting, expense management, and benefits enrollment and administration.

HR Expertise

We use the collective insights and experience of our teams of HR, benefits, risk management and compliance professionals to help clients mitigate many of the administrative, regulatory and practical risks associated with their responsibilities as employers. Our teams provide HR expertises in talent management, recruiting and training, performance management, employee onboarding and terminations, benefits enrollment and support, claims administration and employment practices risk management. In addition, we have the ability to provide benchmarking data and relevant HR form and document templates to our clients to help them run their business. Under our vertical strategy, we tailor our product and service offerings to specific industries by identifying common needs and leveraging scale and shared experience to provide more efficient and relevant offerings.

Benefits

We offer our WSEs access to a broad range of TriNet-sponsored benefit and insurance programs that many of our clients may be unable to obtain for their WSEs on their own and that are compliant with state, local, and federal regulations. Our benefit and insurance service offerings include plan design and administration, enrollment management, and WSE and client communications relating to our sponsored benefits and insurance programs.

We pay premiums to third-party insurance carriers for WSE insurance benefits and reimburse the insurance carriers and third-party administrators for claims payments made on our behalf within our insurance deductible layer, where applicable.

Compliance

Our products and services are designed to help our clients comply with local, state and federal employment and benefit laws. We monitor employer-related developments and assist clients in complying with changing regulations and requirements at all levels, from changes in local minimum wage and family leave ordinances to sweeping reforms such as the Patient Protection and Affordable Care Act (ACA). Often these changes are staggered and require additional guidance from a variety of local, state or federal agencies, making compliance a continuous challenge. Each component of our HR solutions is designed with compliance in mind, whether it is payroll processing and tax administration, HR services focused on creating a compliant workplace, or offering ACA-compliant benefit plans.

MANAGEMENT'S DISCUSSION AND ANALYSIS

Significant Developments in 2017

Our consolidated results for the first six months of 2017 reflect our continued progress with vertical product offerings combined with slower growth in insurance costs as a result of favorable experience in our health programs and cost management with our insurance providers.

We also experienced modest Average WSE growth as compared to the first six months of 2016 as we continued our migration from legacy platforms to our common TriNet platform. Furthermore, we moderated our new customer growth as we prepared for the launch of TriNet Main Street, our new industry vertical product.

Our other operating expenses reflect our continued focus on developing new vertical products and platform integrations, and additional costs associated with our internal control remediation efforts.

We began 2017 with significant operational initiatives to improve our products and platform for our clients. During the first half of 2017 , we provided our users with improved online and mobile productivity tools and upgraded our architecture allowing our platform to integrate more effectively with third party products. In July 2017, we launched TriNet Main Street, our solution for a variety of "main street" industries, including hospitality, retail and manufacturing businesses, and we are currently onboarding new clients for this product.

Performance Highlights

Q2 2017

Our financial performance for the second quarter of 2017 , compared to the same period in 2016 , included:

• Total revenues increased 7% to $800.5 million , due to increased insurance service revenues from higher health coverage participation by our WSEs combined with insurance services price increases, while Net Service Revenues increased 35% to $201.0 million primarily due to the insurance service revenues increases noted above.

• Operating income increased 116% to $56.8 million primarily due to improvement in our insurance service revenues, partially offset by an increase in other operating expenses incurred to support our growth.

• Net income increased 225% to $40.0 million , or $0.56 per diluted share, Adjusted Net Income increased 88% to $36.7 million and Adjusted EBITDA increased 70% to $72.4 million primarily due to increased operating income as described above.

• Operating income increased 103% to $ 106.3 million primarily due to increases in insurance service revenues and moderated growth in insurance costs described above, partially offset by an increase in other operating expenses to support our growth.

5

• Net income increased 188% to $68.7 million , or $0.97 per diluted share, Adjusted Net Income increased 75% to $68.3 million and Adjusted EBITDA increased 60% to $135.7 million primarily due to increased operating income.

• Cash provided by operating activities increased 138% to $104.1 million as a result of increased operating income, reductions in payment of our workers' compensation collateral held by insurance carriers and reduction in cash taxes paid.

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, make planning decisions, allocate resources and 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 useful information that we use in order 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, superior to, or as a substitute for the directly comparable financial measures prepared in accordance with GAAP.

MANAGEMENT'S DISCUSSION AND ANALYSIS

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 represented 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 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 represented 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.
Adjusted EBITDA • Net income, excluding the effects of: - income tax provision, - interest expense, - 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 not directly resulting from our core operations or 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.
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.

(1) We have adjusted the non-GAAP effective tax rate to 40.5% for 2017 from 42.5% for 2016 due to a decrease in state income taxes from an increase in excludable income for state income tax purposes. These non-GAAP effective tax rates exclude the income tax impact from stock-based compensation and changes in uncertain tax positions.

(2) Non-cash interest expense represents amortization and write-off of our debt issuance costs.

MANAGEMENT'S DISCUSSION AND ANALYSIS

Historically, Total WSE comparisons have served as an indicator of our success in growing our business and retaining clients. Average WSE growth is another volume measure we use to monitor the performance of our business.

Average WSEs was flat in the second quarter of 2017 compared to the same period in 2016 and increased 2% in the first half of 2017 compared to the same period in 2016. This 2% increase was driven by WSE growth in our established customer base, largely offset by higher attrition resulting from our disciplined approach of migrating clients to a common platform. Furthermore, we moderated our new customer growth as we prepared for the launch of our new industry vertical, TriNet Main Street.

Anticipated revenues for future periods can diverge from 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. In addition to driving the growth in WSE count, we also focus on pricing strategies and product differentiation to maximize our revenue opportunities. Average monthly total revenues per WSE, as a measure to monitor the success of such pricing strategies, have increased 7% in the second quarter and first half of 2017 compared to the same periods in 2016 .

Professional Service Revenues (PSR)

Professional service revenues represented 14% of total revenues in both the second quarter and first half of 2017 . The slight decrease in professional service revenues during the second quarter of 2017 was primarily attributed to the timing of a payroll tax service fee adjustment.

The 3% increase in PSR during the first half of 2017 was primarily attributed to the 2% growth in Average WSEs when compared to the same period in 2016 .

11

MANAGEMENT'S DISCUSSION AND ANALYSIS

Insurance Service Revenues (ISR)

Insurance service revenues represented 86% of total revenue in the second quarter and first half of 2017. Insurance service revenues increased 9% and 10% in the second quarter and first half of 2017 when compared to the same periods in 2016 . The growth in insurance service revenues for the second quarter and first half of 2017 was equally attributable to increased participation in our health plans and an increase in health insurance service fees per plan participant.

Insurance Costs

Insurance costs remained consistent for the second quarter of 2017, when compared to the same period in 2016 , with flat Average WSEs and costs per Average WSE.

Insurance costs increase d 4% for the first half of 2017, compared to the same period in 2016 , primarily as a result of an increase in health plan participants and a 2% increase in Average WSEs, partially offset by a reduction in monthly insurance claims and premium costs per average participant.

MANAGEMENT'S DISCUSSION AND ANALYSIS

Other Operating Expenses (OOE)

Other operating expenses includes cost of providing services (COPS), sales and marketing (S&M), general and administrative (G&A), and systems development and programming (SD&P) expenses.

We manage other operating expenses and allocate resources across different business functions based on percentage of Net Service Revenues. This ratio has decreased to 68% from 76% in the second quarter of 2017 , and has decreased to 70% from 77% in the first half of 2017 , when compared to the same periods in 2016 . These decreases are due to our revenues increasing faster than other operating expenses.

We had approximately 2,700 corporate employees as of June 30, 2017 in 48 offices across the U.S. Our corporate employees' compensation related expenses represent a majority of our operating expenses. The percentage of compensation related expense to other operating expense has decreased to 66% from 70% in the second quarter of 2017 , and has decreased to 65% from 68% in in the first half of 2017 , when compared to the same periods in 2016 . These decreases are due to increased non-compensation related costs associated with our platform integrations and internal control remediation efforts.

We expect our operating expenses to increase in the foreseeable future due to expected growth, our strategy to develop new vertical products and platform integrations, and additional costs associated with our internal control remediation efforts. We will continue to improve our systems, processes and internal controls to gain efficiencies. These expenses may fluctuate as a percentage of our total revenues from period-to-period depending on the timing of when expenses are incurred.

MANAGEMENT'S DISCUSSION AND ANALYSIS

Q2 2017 - Q2 2016 Commentary

Other operating expenses increased $23.2 million or 20% in the second quarter of 2017 compared to the same period in 2016 as part of our continued investment in supporting our infrastructure and improving our technology platform user experience for our clients. Significant drivers of our increased spending are as follows:

• Compensation costs for our corporate employees including payroll, payroll taxes, stock-based compensation, bonuses, commissions and other payroll and benefits related costs, increased $10.6 million or 13% primarily due to increased headcount related to investments in client service and technology functions to support product delivery and platform integration.

• Consulting expenses increased $4.8 million and included costs associated with enhancing our product offerings as well as payroll tax compliance initiatives.

• Accounting and other professional fees increased $4.8 million in the second quarter of 2017 primarily as a result of increased professional fees to support our internal control remediation efforts.

YTD 2017 - YTD 2016 Commentary

Other operating expenses increased $36.7 million , or 15% , in first half of 2017 compared to the same period in 2016 . Significant drivers of our increased spending are as follows:

• Total compensation costs increased $15.1 million , or 9% , and consulting expenses increased $8.8 million primarily due to the factors described above.

• Accounting and other professional fees increased $2.6 million primarily as a result of the timing of professional fees to support our internal control remediation efforts.

• Other expenses increased $10.2 million primarily due to additional compliance costs and external sales costs.

MANAGEMENT'S DISCUSSION AND ANALYSIS

Amortization of Intangible Assets

Amortization of intangible assets represents costs associated with acquired companies' developed technologies, client lists, trade names and contractual agreements. Amortization expenses decrease d 74% and 73% in the second quarter and first half of 2017 , respectively, compared to the same periods in 2016 , as a result of the revision to the expected useful life in October 2016 of certain client lists and trademarks primarily related to our previous acquisitions.

Depreciation

Depreciation expense increase d 42% and 49% in the second quarter and first half of 2017 , respectively, compared to the same periods in 2016 , as a result of our additional investment in technology products and platforms and the associated depreciation of those assets.

Other Income (Expense)

Other income (expense) consists primarily of interest expense under our credit facility, which decrease d 4% and 5% in the second quarter and first half of 2017 , respectively, compared to the same periods in 2016 due to a decreasing principal balance on our outstanding debt.

Provision for Income Taxes

Our effective tax rate (ETR) was 23.5% for the second quarter of 2017 , compared to an ETR of 42.9% for the same period in 2016 . The 19.4% decrease in ETR is primarily due to the following:

• a decrease of 12.0% , or $6.5 million , attributable to tax benefits recognized from the adoption of Accounting Standards Update 2016-09 - Stock Compensation (ASU 2016-09) additionally described in Note 1 of our condensed consolidated financial statements and related notes,

• a decrease of 4.3% in state income taxes from an increase in excludable income for state income tax purposes and changes in apportionment and statutory tax rates,

• a decrease of 2.3% in non-deductible expenses due to the abatement of penalties previously assessed by the Internal Revenue Service (IRS), and

• a decrease of 0.8% resulting from an increase in tax credits and decrease in non-deductible stock-based compensation.

Our ETR was 29.3% for the first half of 2017 , compared to an ETR of 43.6% for the same period in 2016 . The 14.3% decrease in ETR is primarily due to the following:

• a decrease of 10.1%, or $10.1 million, attributable to tax benefits recognized from the adoption of ASU 2016-09,

• a decrease of 3.8% in state income taxes from an increase in excludable income for state income tax purposes and changes in apportionment and statutory tax rates,

• a decrease of 2.4% resulting from an increase in tax credits and decrease in both non-deductible stock-based compensation and non-deductible expenses, partially offset by a

• an increase of 2.0% due to changes in uncertain tax positions where we may not prevail in our position associated with state income tax audits.

MANAGEMENT'S DISCUSSION AND ANALYSIS

Liquidity and Capital Resources

Liquidity

We manage our liquidity separately between assets and liabilities that are WSE related from our corporate assets and liabilities.

WSE related assets and liabilities primarily consist of current assets and current 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. Our cash flows related to WSE payroll and benefits is generally matched by advance collection from our clients which is reported as payroll funds collected within WSE related assets.

We report our corporate cash and cash equivalents on the condensed consolidated balance sheets separately from WSE related assets. We rely on our corporate cash and cash equivalents and cash from operations to satisfy our operational and regulatory requirements and to fund capital expenditures. We believe that we have sufficient corporate liquidity and capital resources to satisfy future requirements and meet our obligations to clients, creditors and debt holders. We believe that our existing corporate cash and cash equivalents, working capital and cash provided by operating activities will be sufficient to meet our working capital and capital expenditure needs for at least the next 12 months.

Our liquid assets are as follows:

(in thousands) June 30, 2017 December 31, 2016
Cash and cash equivalents $ 233,883 $ 184,004
Working capital:
Corporate working capital 163,195 151,295
WSE related assets, net of WSE related liabilities 5,486 5,476

We manage our sponsored benefit and workers' compensation insurance obligations by maintaining funds in restricted cash, cash equivalents and investments as collateral. As of June 30, 2017 , we had $155.3 million of restricted cash, cash equivalents and investments included in WSE related assets and $150.9 million of marketable securities designated as long-term restricted cash, cash equivalents and investments on the condensed consolidated balance sheets. These collateral amounts are generally determined at the beginning of each plan year and we may be required by our insurance carriers to adjust the balance when facts and circumstances change. We regularly review our collateral balances with our insurance carriers, and anticipate funding further collateral as needed based on program development.

Capital Resources

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 operations, our borrowing capacity under our revolving credit facility and the potential issuance of debt or equity securities.

We maintain a $75.0 million revolving credit facility. The total unused portion of our revolving credit facility was $59.5 million as of June 30, 2017 .

MANAGEMENT'S DISCUSSION AND ANALYSIS

Cash Flows

We generated positive cash flows from operating activities for the first half of 2017 and 2016 . We also have borrowing capacity under our revolving credit facility and the potential to generate cash through the issuance of debt or equity securities, to meet short-term funding requirements. The following table presents our cash flow activities for the stated periods:

(in thousands) Six Months Ended June 30, — 2017 2016
Net cash provided by (used in):
Operating activities $ 104,113 $ 43,667
Investing activities (9,256 ) (6,975 )
Financing activities (45,141 ) (36,230 )
Effect of exchange rates on cash and cash equivalents 163 24
Net increase in cash and cash equivalents $ 49,879 $ 486

Operating Activities

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

(in thousands) Six Months Ended June 30, — 2017 2016
Net income $ 68,688 $ 23,859
Depreciation and amortization 16,496 17,919
Stock-based compensation expense 13,706 13,905
Payment of interest (8,006 ) (8,091 )
Income tax (payments) refunds, net 169 (21,374 )
Collateral (paid to) refunded from insurance carriers, net 4,729 (14,053 )
Changes in other operating assets and liabilities 8,331 31,502
Net cash provided by operating activities $ 104,113 $ 43,667

The period-to-period fluctuation in cash provided by operating activities is primarily driven by the 188% increase in our net income, changes in other operating assets and liabilities, which are primarily driven by timing of payments related to WSE related assets and liabilities and our accrued expenses related to corporate employee compensation related payables, reductions to our taxes paid, and decreases in collateral payments made to our insurance carriers.

MANAGEMENT'S DISCUSSION AND ANALYSIS

Investing Activities

Net cash used in investing activities in the first half of 2017 and 2016 primarily consisted of cash paid for capital expenditures, offset partially by proceeds from the maturity of investments.

(in thousands) Six Months Ended June 30, — 2017 2016
Capital expenditures:
Software and hardware $ 13,279 $ 12,870
Office furniture, equipment and leasehold improvements 7,446 3,844
Cash used in capital expenditures $ 20,725 $ 16,714
Investments:
Purchases of restricted investments $ — $ (14,959 )
Proceeds from maturity of restricted investments 11,469 24,998
Cash provided by investments $ 11,469 $ 10,039

Capital expenditures increased in the first half of 2017 compared to the same period in 2016 , primarily due to the build out of our technology and client service centers. We also increased our investments in software and hardware to introduce new products, enhance existing products and platforms, as well as complete platform integrations. We expect capital investments in our software and hardware to continue in the future.

We invest cash held as collateral to satisfy our long-term obligation towards the workers' compensation liabilities in U.S. long-term treasuries and mutual funds. We review the amount of investment and the anticipated holding period regularly, in conjunction with our estimated long-term workers' compensation liabilities and anticipated claims payment trend.

Financing Activities

Net cash used in financing activities in the first half of 2017 and 2016 consisted primarily of repurchases of our common stock and repayment of debt.

The board of directors from time to time authorizes stock repurchases of our outstanding common stock primarily to offset dilution from the issuance of stock under our equity-based incentive plan and employee stock purchase plan. During the first half of 2017 , we repurchased 1.1 million shares of common stock for $29.5 million . As of June 30, 2017 , approximately $30.5 million remained available for repurchase. Our debt repayments were also $3.7 million lower in the first half of 2017 compared to the same periods in 2016 .

Critical Accounting Policies, Estimates and Judgments

There have been no material changes to our critical accounting policies as discussed in our 2016 Form 10-K.

Refer to Note 1 in the condensed consolidated financial statements and related notes included in this Form 10-Q.

QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK AND CONTROLS AND PROCEDURES

Quantitative and Qualitative Disclosures About Market Risk

There has been no material change in our exposure to market risks from that discussed in Item 7A of our 2016 Form 10-K.

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, 2017 . The term “disclosure controls and procedures,” as defined in Rules 13a-15(e) and 15d-15(e) under the Securities Exchange Act of 1934, as amended, or the Exchange Act, means controls and other procedures of a company that are designed to ensure that information required to be disclosed by a company in the reports that it files or submits under the Exchange Act is recorded, processed, summarized and reported, within the time periods specified in the SEC’s rules and forms.

Disclosure controls and procedures include, without limitation, controls and procedures designed to ensure that information required to be disclosed by a company in the reports that it files or submits under the Exchange Act is accumulated and communicated to the company’s management, including its principal executive officer and principal financial officer, as appropriate to allow timely decisions regarding required disclosure. Based on the evaluation of our disclosure controls and procedures as of June 30, 2017 , our Chief Executive Officer and Chief Financial Officer concluded that, as of such date, our disclosure controls and procedures were not effective as a result of the material weaknesses in our internal control over financial reporting. A material weakness is a deficiency, or a combination of deficiencies, in internal control over financial reporting such that there is a reasonable possibility that a material misstatement of our annual or interim financial statements will not be prevented or detected on a timely basis.

Notwithstanding the material weaknesses in our internal control over financial reporting, 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 accounting principles generally accepted in the United States of America. Additionally, the material weaknesses did not result in any restatements of our condensed consolidated financial statements or disclosures for any prior period.

Additional Analyses and Procedures and Remediation Plan

We are taking specific steps to remediate the material weaknesses identified by management and described in greater detail in our 2016 Form 10-K. Although we intend to complete the remediation process with respect to these material weaknesses as quickly as possible, we cannot at this time estimate how long it will take, and our remediation plan may not prove to be successful.

Because the reliability of the internal control process requires repeatable execution, the successful remediation of these material weaknesses will require review and evidence of effectiveness prior to concluding that the controls are effective and there is no assurance that additional remediation steps will not be necessary. As such, as we continue to evaluate and work to improve our internal control over financial reporting, our management may decide to take additional measures to address the material weaknesses or modify the remediation steps already underway. As noted above, although we plan to complete the remediation process as quickly as possible, we cannot at this time estimate how long it will take, and our initiatives may not prove to be successful. Accordingly, until these weaknesses are remediated, we plan to perform additional analyses and other procedures to ensure that our condensed consolidated financial statements are prepared in accordance with GAAP.

Changes in Internal Control Over Financial Reporting

Other than the remediation efforts underway, 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, 2017 , 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.

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 (PEO) founded in 1988, provides comprehensive human resources (HR) solutions for small to midsize businesses (SMBs) under a co-employment model. These HR solutions include bundled services, such as 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 services. Through the co-employment relationship, we are the employer of record for most administrative and regulatory purposes, including:

• compensation through wages and salaries,

• employer payroll-related taxes payment,

• employee payroll-related taxes withholding and payment,

• 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 worksite employees (WSEs).

We operate in one reportable segment. All of our service revenues are generated from external clients. Less than 1% of revenue is generated outside of the U.S.

Basis of Presentation

These unaudited condensed consolidated financial statements (Financial Statements) and accompanying notes have been prepared in accordance with accounting principles generally accepted in the United States of America (GAAP) 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 (SEC). Certain information and note disclosures included in the 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, which are normal and recurring in nature, necessary for fair financial statement presentation. The results of operations for the second quarter of 2017 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 of our Annual Report on Form 10-K for the year ended December 31, 2016 ( 2016 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. Significant estimates include:

• liability for unpaid losses and loss adjustment expenses (loss reserves) related to workers' compensation and workers' compensation collateral receivable,

• health insurance loss reserves,

• liability for insurance premiums payable,

• impairments of goodwill and other intangible assets,

• income tax assets and liabilities, and

• liability for legal contingencies.

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

Recent Accounting Pronouncements

Recently adopted accounting guidance

Share-based payments - In March 2016, the FASB issued ASU 2016-09- Stock Compensation (Topic 718): Improvements to Employee Share-Based Payment Accounting , as part of the Simplification Initiative to simplify certain aspects of the accounting for share-based payment transactions to employees. The new standard requires excess tax benefits and tax deficiencies to be recorded in the statements of income as a component of the provision for income taxes when stock awards vest or are settled. In addition, it eliminates the requirement to reclassify cash flows related to excess tax benefits from operating activities to financing activities on the condensed consolidated statements of cash flows. The standard also provides an accounting policy election to account for forfeitures as they occur, allows us to withhold more of an employee’s vesting shares for tax withholding purposes without triggering liability accounting, and clarifies that all cash payments made to tax authorities on an employee’s behalf for withheld shares should be presented as a financing activity on our cash flows statement. The new standard was effective for us beginning January 1, 2017.

Upon adoption, excess tax benefits or deficiencies from share-based award activity were reflected in the condensed consolidated statements of income as a component of the provision for income taxes, whereas they previously were recognized in equity. We also elected to account for forfeitures as they occur, rather than estimate expected forfeitures. The adoption of ASU 2016-09 resulted in a net cumulative-effect adjustment of $0.3 million , reflected as an increase to retained earnings as of January 1, 2017, mostly related to the recognition of the previously unrecognized excess tax benefits using the modified retrospective method. The previously unrecognized excess tax effects were recorded as an increase to deferred tax assets.

We adopted the aspects of the standard affecting the cash flow presentation retrospectively, and accordingly, to conform to the current year presentation, we reclassified $0.7 million of tax deficiencies under financing activities to operating activities for the period ended June 30, 2016 , on our condensed consolidated statements of cash flows. The presentation requirements for cash flows related to employee taxes paid for withheld shares had no impact to any of the periods presented on our condensed consolidated statements of cash flows since such cash flows have historically been presented as a financing activity.

Recently issued accounting pronouncements

Lease arrangements - In February 2016, the FASB issued ASU 2016-02- Leases. The amendment requires that lease arrangements longer than 12 months result in an entity recognizing lease assets and lease liabilities. Most significant impact is on those leases classified as operating leases under previous U.S. GAAP. Under the new standard, disclosures are required to meet the objective of enabling users of financial statements to assess the amount, timing, and uncertainty of cash flows arising from leases.

The amendment is effective for annual reporting periods, and interim periods within those years beginning after December 15, 2018. We currently anticipate adoption of the new standard effective January 1, 2019.

We anticipate this standard will have a material impact on our condensed consolidated financial statements. While we are continuing to assess all potential impacts of the standard, we currently believe the most significant impact relates to our accounting for equipment, office and data-center operating leases.

Financial Instruments - In January 2016, the FASB issued ASU 2016-01- Recognition and Measurement of Financial Assets and Financial Liabilities . The amendment addresses various aspects of the recognition, measurement, presentation, and disclosure for financial instruments. The amendment is effective for annual reporting periods, and interim periods within those years beginning after December 15, 2017. Early adoption by public entities is permitted only for certain provisions. We are currently in the process of evaluating the impact of the adoption of this standard on our condensed consolidated financial statements.

24

FINANCIAL STATEMENTS

Revenue Recognition - In May 2014, the FASB issued ASU 2014-09- Revenue from Contracts with Customers , which will replace most existing revenue recognition guidance under GAAP. The core principle of the guidance is that an entity should recognize revenue for the transfer of promised goods or services to customers that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. The standard provides a five-step analysis of transactions to determine when and how revenue is recognized. In July 2015, the FASB deferred the effective date to annual reporting periods, and interim periods within those years, beginning after December 15, 2017. Early adoption at the original effective date of December 15, 2016 is permitted. The amendments may be applied retrospectively or as a cumulative-effect adjustment as of the date of adoption. In March, April and May 2016, the FASB issued ASU 2016-08 Principal versus Agent Considerations (Reporting Revenue Gross versus Net), ASU 2016-10 Identifying Performance Obligations and Licensing, ASU 2016-12 Narrow-Scope Improvements and Practical Expedients and ASU 2016-20 Technical Corrections and Improvements, respectively, providing further clarification to be considered when implementing ASU 2014-09. The guidance permits two methods of adoption: retrospectively to each prior reporting period presented (full retrospective method), or retrospectively with the cumulative effect of initially applying the guidance recognized at the date of initial application (the modified retrospective method). We currently anticipate adopting the new standard effective beginning January 1, 2018 using the modified retrospective method.

Under the modified retrospective method, the new standard will be applied to all contracts initiated on or after the effective date. For contracts with remaining obligations as of the effective date, opening retained earnings will be adjusted for the cumulative effect of the change to the new standard as of the effective date.

We anticipate this standard will have a material impact on our condensed consolidated financial statements. While we are continuing to assess all potential impacts of the standard, we currently believe the adoption will have material impact on our accounting for sales commission expense, income tax provision and deferred taxes. We anticipate that certain client acquisition costs will be deferred over the expected client tenure. We expect our professional service revenues and insurance service revenues will remain substantially unchanged. The actual revenue recognition treatment required under the standard will be dependent on contract specific terms, and may vary in some instances from recognition at the time of billing.

Statement of Cash Flows - In November and August 2016, the FASB issued (ASU) 2016-18 - Statement of Cash Flows (Topic 230): Restricted Cash and 2016-15- Statement of Cash Flows (Topic 230): Classification of Certain Cash Receipts and Cash Payments. The new guidance is intended to reduce diversity in practice in how restricted cash and other certain transactions are classified in the statement of cash flows. The amendments are effective for annual reporting periods, and interim periods within those years, beginning after December 15, 2017. Early adoption is permitted, provided that all of the amendments are adopted in the same period. The guidance requires application using a retrospective transition method.

As of June 30, 2017 and December 31, 2016 , we had total restricted cash, restricted cash equivalents and payroll funds collected of $741.1 million and $1.0 billion , respectively. Currently, changes in these balances are presented as operating cash activities in the condensed consolidated statements of cash flows. Under the new guidance, changes in these amounts will be included with cash and cash equivalents when reconciling the beginning-of-period and end-of-period total amounts shown on the condensed consolidated statements of cash flows.

Although there are several other new accounting pronouncements issued or proposed by the FASB, which we have adopted or will adopt, as applicable, we do not believe any of these other accounting pronouncements have had or will have a material impact on its consolidated financial position, operating results or statements of cash flows.

NOTE 2. CASH, CASH EQUIVALENTS AND INVESTMENTS

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 portion of these trust accounts as restricted cash and cash equivalents in WSE related assets, and the long term portion as restricted cash, cash equivalents and investments on the condensed 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. These amounts that are prefunded by clients are included in WSE related assets as payroll funds collected and are designated to pay pending payrolls and other WSE related liabilities.

Our total corporate and WSE related cash, cash equivalents and investments are summarized below:

NOTE 3. WORKSITE EMPLOYEE RELATED ASSETS AND LIABILITIES

WSE related assets and WSE related liabilities are intended to be reviewed together when considering the financial position of the Company. Our clients direct the price and service specifications for payroll and payroll taxes and as a result, we are not the primary obligor for payroll and payroll tax payments and therefore record these amounts net in our statements of income and comprehensive income. However, we record without offset, accrued wages and payroll tax liabilities for WSEs in WSE related liabilities with the related payroll funds collected and unbilled revenues in WSE related assets. We have classified these assets and liabilities and other service related amounts collectively as WSE related, to present a clearer picture of the inter-relationship of the balances and distinguish these from our other corporate assets and liabilities.

In addition to unbilled revenues, accrued wages and payroll tax liabilities, other significant balances included in the WSE related assets and liabilities include:

• Payroll funds collected, which represents cash collected from clients in advance to fund payroll and payroll taxes, and other payroll related liabilities;

• Other payroll assets, which primarily include payroll tax receivables;

• Client deposits, which represents indemnity guarantee payments received from clients and collections from clients in excess of payroll and other payroll related liabilities;

• Other payroll withholdings, which primarily includes withholdings under 401(k) plans and flexible benefit plans.

Total loss reserves, net of carrier collateral offset $ 222,649 $ 223,003

(1) Included in WSE related liabilities within Note 3 to these condensed consolidated financial statements.

Incurred claims related to prior years represent changes in estimates for ultimate losses on workers' compensation claims. For the three and the six months ended June 30, 2017 , the favorable development was primarily due to lower than expected frequency of reported claims associated with our office WSEs, partially offset by increased severity of reported claims with our non-office WSEs in recent accident years.

As of June 30, 2017 and December 31, 2016 , we had $59.3 million and $65.6 million , respectively, of collateral held by insurance carriers of which $32.0 million and $31.6 million , respectively, was offset against workers' compensation loss reserves as the agreements permit and are net settled of insurance obligations against collateral held. Collateral paid to each carrier for a policy year in excess of our loss reserves are recorded as workers' compensation collateral receivable.

NOTE 5. FINANCIAL INSTRUMENTS AND FAIR VALUE MEASUREMENTS

Cash, Cash equivalents and Restricted Investments

We classify our cash, cash equivalents and restricted investments in marketable securities within Level I in the fair value hierarchy because we use quoted market prices to determine the fair value. We classify our certificates of deposit within Level II in the fair value hierarchy as we use a market approach that compares fair values on certificates with similar maturities. We have no available for sale securities included in Level III as of June 30, 2017 and December 31, 2016 . There was no transfer of any assets and liabilities between Levels during the three months ended June 30, 2017 or the year ended December 31, 2016 .

The following table summarizes our investments by significant categories and fair value measurements on a recurring basis as of June 30, 2017 and December 31, 2016 .

(in thousands) Maturity (in years) Amortized Cost Gross Unrealized Gains Gross Unrealized Losses Fair Value

Level 2:
Certificates of deposit < 1 $ 2,320 $ — $ — $ 2,320
Total $ 54,196 $ 30 $ (77 ) $ 54,149

There were no realized gains or losses for the six months ended June 30, 2017 and 2016 . We had $0.1 million gross unrealized losses in our U.S. Treasury securities as of June 30, 2017 and December 31, 2016 , respectively. The fair value of these securities in an unrealized loss position represented 87% and 58% of the total fair value of all U.S. Treasury securities as of June 30, 2017 and December 31, 2016 , respectively.

Unrealized losses are principally caused by changes in interest rates. In analyzing an issuer's financial condition, we consider whether the securities are issued by the federal government or its agencies, whether downgrades by bond rating agencies have occurred, and industry analysts' reports. As we have the ability and intent to hold these available for sale marketable securities until maturity, or for the foreseeable future, no decline was deemed to be other-than-temporary.

Notes Payable

The carrying value of our notes payable at June 30, 2017 and December 31, 2016 was $443.8 million and $462.9 million , respectively. The estimated fair values of our notes payable at June 30, 2017 and December 31, 2016 were $446.0 million and $462.9 million , respectively. These valuations are considered Level II in the hierarchy for fair value measurement and are based on quoted market prices.

Stock Repurchases

The board of directors authorizes repurchases through an ongoing program initiated in May 2014. During the six months ended June 30, 2017 , we repurchased 1.1 million shares of common stock for $29.5 million . As of June 30, 2017 , $30.5 million remained available for further repurchases of our common stock under our ongoing stock repurchase program.

NOTE 7. EARNINGS PER SHAR E (EPS)

The following table presents the computation of our basic and diluted EPS attributable to our common stock:

(in thousands, except per share data) Three Months Ended June 30, — 2017 2016 Six Months Ended June 30, — 2017 2016

NOTE 8. INCOME TAXES

Our effective income tax rate was 23.5% and 42.9% for the three months ended June 30, 2017 and 2016 , respectively, and 29.3% and 43.6% for the six months ended June 30, 2017 and 2016 , respectively. The decrease is primarily due to a discrete tax benefit recognized upon adoption of ASU 2016-09, a tax benefit from an increase in excludable income for state tax purposes which is partially offset by a discrete charge due to changes in uncertain tax positions, and a tax benefit in non-deductible expenses due to the abatement of penalties previously assessed by the Internal Revenue Service (IRS). The remaining decrease is attributable to tax credits and disqualifying dispositions of previously nondeductible stock based compensation.

During the six months ended June 30, 2017 , our unrecognized tax benefits increased from $0.9 million to $3.4 million . Of the $3.4 million , $2.0 million would affect our tax expense, if recognized. Included in the $2.0 million is $0.2 million for interest and $0.2 million for penalties. Our unrecognized tax benefits are not expected to change significantly during the next 12 months.

We are subject to tax in U.S. federal and various state and local jurisdictions, as well as Canada. We are not subject to any material income tax examinations in federal or state jurisdictions for tax years prior to January 1, 2011. We previously paid Notices of Proposed Assessments disallowing employment tax credits totaling $10.5 million , plus interest and penalties of $4.0 million in connection with an IRS examination of Gevity HR, Inc. and its subsidiaries, which were acquired by TriNet in June 2009. This issue is being resolved through litigation. With regard to these employment tax credits, we believe it is more likely than not that we will prevail and realize our receivable included in other noncurrent assets without a charge to our statement of income. Therefore, no reserve has been recognized related to this matter.

NOTE 9. COMMITMENTS AND CONTINGENCIES

Lease Commitments

We lease office facilities, including our headquarters and other facilities, and equipment under non-cancelable operating leases. For detail of these commitments refer to Note 13 in Part II, Item 8 in our 2016 Form 10-K.

In July 2017, we entered into an agreement to lease additional office space starting February 2018 for a total commitment of approximately $32.4 million over 10 years.

Credit Facilities

We maintain a $75.0 million revolving credit facility which includes capacity for a $40.0 million letter of credit facility and a $10.0 million swingline facility. Letters of credit issued pursuant to the revolving credit facility reduce the amount available for borrowing under the revolving credit facility. The total unused portion of the revolving credit facility was $59.5 million as of June 30, 2017 .

The terms of the credit agreement governing the revolving credit facility require us to maintain certain financial ratios at each quarter end. We were in compliance with these financial covenants at June 30, 2017 .

We also have a $ 5.0 million line of credit facility to secure standby letters of credit related to our workers' compensation obligations. At June 30, 2017 , the total unused portion of the credit facility was $ 2.7 million .

Standby Letters of Credit

We have two unused standby letters of credit totaling $17.8 million provided as collateral for our workers’ compensation obligations. At June 30, 2017 , the facilities were not drawn down.

FINANCIAL STATEMENTS

Contingencies

In August 2015, Howard Welgus, a purported stockholder, filed a putative securities class action lawsuit, Welgus v. TriNet Group, Inc. et. al., under the Securities Exchange Act of 1934 in the United States District Court (the Court) for the Northern District of California. The complaint was later amended in April 2016. The amended complaint generally alleges that TriNet and the other defendants caused damage to purchasers of our stock by misrepresenting and/or failing to disclose facts generally pertaining to alleged trends affecting health insurance and workers' compensation claims. The other defendants include certain of our officers and directors, General Atlantic, LLC, a former significant shareholder, and the underwriters of our IPO. The court set September 2017 for a court hearing on our motion to dismiss. We are unable to reasonably estimate the possible loss or range of losses, if any, arising from this litigation.

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 condensed 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 or the above mentioned securities class action 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.

As of June 30, 2017 we had approximately $30.5 million remaining for repurchases under our stock repurchase program. Stock repurchases under the program are primarily intended to offset the dilutive effect of share-based employee incentive compensation. The purchases were funded from existing cash and cash equivalents balances.

Our stock repurchases and dividends are subject to certain restrictions under the terms of our credit facility. For more information about our credit facility and our stock repurchases, refer to Notes 8 and 9 in Part II, Item 8 of our 2016 Form 10-K.
