MANAGEMENT'S DISCUSSION AND ANALYSIS |

Management’s Discussion and Analysis of Financial Condition and Results of Operations
Executive Summary
Overview
TriNet is a leading provider of human resources (HR) solutions for small to midsize businesses (SMBs). Under our co-employment model, we assume certain of the responsibilities of being an employer and help our clients mitigate employer-related risks and manage many of the complex and burdensome administrative and compliance responsibilities associated with employment.
Our solutions include payroll processing, tax administration, access to employee benefits and an HR technology platform with online and mobile tools that allow our clients and worksite employees (WSEs) to store, view and manage their core HR-related information and efficiently conduct a variety of HR-related transactions anytime and anywhere.
We operate in one reportable segment. Less than 1% of our revenue is generated outside of the U.S.
Significant Developments in 2018
Our consolidated results for the three months ended March 31, 2018 reflect continued progress in our industry-oriented (vertical) products and for our insurance service offerings, combined with higher WSE enrollment growth within our medical plans and slower growth in insurance costs.
We experienced a decline in Average WSEs as compared to the first three months of 2017 due to the migration of clients from our legacy (SOI) platform onto our common TriNet platform and increased new customer growth as we launched and expanded the functionality of TriNet Main Street.
In summary, we:

• | Completed the migration of existing clients from the SOI platform onto our common TriNet platform so that all our clients can benefit from our investment in platform and product improvements,

• | Continued to strengthen our leadership team with the addition of executives in our sales, marketing and operations functions,

• | Benefited from increased sales force retention and product pricing strength,

• | Benefited from increased medical plan enrollment,

• | Benefited from changes in October 2017 with one of our health insurance carriers, where we converted an insurance carrier contract from a guaranteed-cost to risk-based insurance plan, and

• | Continued to invest in improving our internal control environment to support our ongoing compliance with the requirements of Sarbanes-Oxley Act of 2002 (SOX).

MANAGEMENT'S DISCUSSION AND ANALYSIS |

Non-GAAP Financial Measures
In addition to financial measures presented in accordance with U.S. Generally Accepted Accounting Principles (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 plans. 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 from, as superior to, or as a substitute for the directly comparable financial measures prepared in accordance with GAAP.

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 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 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 WSE related costs which are substantially pass-through for the benefit of WSEs. Under GAAP, insurance service revenues and costs are recorded gross as we have latitude in establishing the price, service and supplier specifications. • We also sometimes refer to Net Insurance Service Margin, which is the ratio of Net Insurance Revenue to Insurance Service Revenues.

MANAGEMENT'S DISCUSSION AND ANALYSIS |

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 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. • We also sometimes refer to Adjusted EBITDA Margin, which is the ratio of Adjusted EBITDA to Net Service 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 as described above, debt payment premiums and our secondary offering costs as these are not directly resulting from our core operations or indicative of our ongoing operations.

(1) | We have adjusted the non-GAAP effective tax rate to 26% for 2018 from 41% for 2017 due primarily to a decrease in the statutory rate from 35% to 21%. These non-GAAP effective tax rates exclude the income tax impact from stock-based compensation, changes in uncertain tax positions, and nonrecurring benefits or expenses from federal legislative changes.

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

MANAGEMENT'S DISCUSSION AND ANALYSIS |

Results of Operations
Operating Metrics
Worksite Employees (WSE)
Average WSE growth is a volume measure we use to monitor the performance of our business. Average WSEs decreased 4% in the first quarter of 2018 compared to the same period in 2017. The decline during the quarter in Average WSEs rate was a result of attrition, including attrition from migrating certain of our clients to our common platform, partially offset by WSE growth due to new sales and hiring within our installed base. We expect attrition to remain elevated until the third quarter of 2018 as our migrated clients respond to our service offerings.
Historically, Total WSE comparisons have served as an indicator of our success in growing our business and retaining clients. 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. We report the additional volume growth we obtain from the changes in WSE participation in our major services (including health services) or vertical products as a change in mix.

10

MANAGEMENT'S DISCUSSION AND ANALYSIS |

Revenues and Income
Our revenues consist of professional service revenues (PSR) and insurance service revenues (ISR). Professional service revenues represent 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. Insurance service revenues consist 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 addition to focusing on growing our Average WSE and Total WSE counts, we also focus on pricing strategies and product differentiation to expand our revenue opportunities. Monthly total revenues per Average WSE, as a measure to monitor the success of such strategies, has increased 11% in the first quarter of 2018 compared to the same period in 2017.
Q1 2018 - Q1 2017 Commentary
Total revenues were $861 million for the first quarter of 2018, a 7% increase compared to the same period in 2017.

• | Insurance service revenues grew 7% over the same quarter in 2017 to $732 million due primarily to increased participation in our health plans combined with an increase in health insurance service fees per plan participant, partially offset by a decline in Average WSEs.

• | Professional service revenues increased 7% over the same quarter in 2017 to $129 million due primarily to rate increases.

Operating income was $71 million, up 43% from the first quarter of 2017, primarily due to improvement in our insurance service revenues as noted above, combined with favorable developments from insurance costs.

11

MANAGEMENT'S DISCUSSION AND ANALYSIS |

Net Service Revenues
Net Service Revenues (total revenues less insurance costs) provides a comparable basis of revenues on a net basis, and acts as the basis to allocate resources to different functions, and helps us evaluate the effectiveness of our business strategies by each business function.
Q1 2018 - Q1 2017 Commentary
Net Service Revenues were $220 million for 2018, representing a 11% increase from 2017. This was driven by an increase in Net Insurance Service Revenues, which grew 16% over 2017. Monthly total service revenues per Average WSE increased 11%, while monthly insurance costs per Average WSE increased 10%.

12

MANAGEMENT'S DISCUSSION AND ANALYSIS |

Professional Service Revenues (PSR)
Our clients are billed either based on a fee per WSE per month per transaction or on a percentage of the WSEs’ payroll. For those clients that are billed on a percentage of WSEs' payroll, as our clients' payrolls increases our fees will also increase. As such, payroll and payroll taxes processed is also an indicator of our PSR growth.
Our investment in a vertical approach provides us the flexibility to offer our clients in different industries with varied services at different prices. We believe that this vertical approach will improve our ability to retain our customers, but which also potentially reduces the value of using WSEs as the only leading indicator of future revenue performance.

13

MANAGEMENT'S DISCUSSION AND ANALYSIS |

Insurance Service Revenues (ISR)
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.
ISR represented 85% of total revenues and increased 7% in the first quarter of 2018 as compared to the first quarter of 2017.

14

MANAGEMENT'S DISCUSSION AND ANALYSIS |

Insurance Costs
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 loss reserves related to our workers' compensation and health benefit insurance.
Insurance costs as a percentage of ISR of 88% in the first quarter of 2018 were comparable to 89% in the first quarter of 2017.

15

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 our other operating expenses and allocate resources across different business functions based on OOE as a percentage of Net Service Revenues which decreased to 64% in the first quarter of 2018 from 71% in the same period in 2017.
At March 31, 2018, we had approximately 2,700 corporate employees in 49 offices across the United States. Our corporate employees' compensation related expenses represent the majority of our operating expenses. Compensation costs for our corporate employees include payroll, payroll taxes, stock-based compensation, bonuses, commissions and other payroll and benefits related costs.
The percentage of compensation related expenses to OOE is 69% and 64% in the first quarter of 2018 and 2017, respectively. This increase is due to decreased non-compensation related costs associated with compliance initiatives and internal control remediation efforts.
We expect our OOE to increase in the foreseeable future due to expected growth, our continued strategy to develop new vertical products, continued platform integrations, and additional costs associated with our continued efforts to improve our systems, processes, and internal controls. These expenses may fluctuate as a percentage of our total revenues from period-to-period depending on the timing of when expenses are incurred.

16

MANAGEMENT'S DISCUSSION AND ANALYSIS |

Q1 2018 - Q1 2017 Commentary
Other operating expenses in the first quarter of 2018 remained consistent with the same period in 2017. Specific costs varied as follows:

• | Total compensation costs increased $7 million, or 7%, primarily due to a:

▪ | $16 million increase associated with the following functions:

▪ | client services and information technology to support the growth and migration of clients to our common TriNet platform,

▪ | risk service to strengthen our insurance business, and

▪ | other support functions as a result of increased operational and compliance requirements,

▪ | partially offset by a decrease of $9 million in commission expense with the adoption of ASC Topic 606 in the first quarter of 2018. Refer to Note 1 in Item 1 of this Form 10-Q for additional details surrounding the impact of this adoption.

• | Consulting expenses decreased $3 million primarily due to increased capitalization of costs related to our enhanced product offerings.

• | Other expenses decreased $6 million primarily due to the timing of compliance costs.

Other Income (Expense)
Other income (expense), consists primarily of interest expense under our credit facility offset by interest and dividend from income from investments.
We may seek to amend our credit facility when appropriate and if available terms become more favorable, although we can provide no assurances that we will be able to do so. We may also seek additional debt capital to fund acquisitions, accelerate the payment of principal on outstanding debt, or for other business purposes. As such, our interest expense may fluctuate as a percentage of our total revenues from period to period depending on the timing of those borrowing and or repayment activities.

17

MANAGEMENT'S DISCUSSION AND ANALYSIS |

Provision for Income Taxes
Our effective income tax rate was 20% and 36% for the first quarter of 2018 and 2017, respectively. The decrease was primarily attributable to a reduction of the federal corporate income tax rate from 35% to 21% on January 1, 2018 under the Tax Cuts and Jobs Act (TCJA). The decrease is also attributable to charges for uncertain income tax positions arising from state tax exposures recorded in the same period in 2017. The remaining impacts consisted of tax benefits recognized from excess tax benefits related to stock-based compensation and an increase in excludable income for state income tax purposes.
Liquidity and Capital Resources
Liquidity
We report our liquidity separately between assets and liabilities that are WSE-related and our corporate assets and liabilities. 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. Our liquid assets are as follows:

| March 31, 2018 | December 31, 2017
(in millions) | Corporate | WSE | Total | Corporate | WSE | Total
Current assets |  |  |  |  |  |

Working capital | $ | 247 |  | $ | — |  | $ | 247 |  | $ | 227 |  | $ | 7 |  | $ | 234 |

Working capital for WSE-related assets and liabilities
We present our WSE-related assets and liabilities separately from our corporate assets and liabilities on our condensed consolidated balance sheets to better distinguish those assets and liabilities held by us to cover WSE-related obligations. 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 insurance programs, and other benefit programs.
We designate funds to ensure that we have adequate current assets to satisfy our current WSE-related obligations.
We manage our WSE payroll and benefits obligations through collecting payment from our clients which generally occurs two to three days in advance of the client's payroll date. We regularly review our short-term WSE-related obligations (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 payroll funds collected (PFC). PFC is included in current assets as restricted cash, cash equivalents and investments in our condensed consolidated financial statements.
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 the balance when facts and circumstances change. We regularly review our collateral balances with our insurance carriers, and anticipate funding further collateral based upon our capital requirements. We classify our restricted cash, cash equivalents and investments as current and non-current assets to match against the anticipated payment of claims.

MANAGEMENT'S DISCUSSION AND ANALYSIS |

Working capital for corporate purposes
We use the remaining available cash and cash equivalents and cash from operations to satisfy our operational and regulatory requirements and to fund capital expenditures. We believe that our existing corporate cash and cash equivalents and positive working capital will be sufficient to meet our working capital and capital expenditure needs for at least the next 12 months. Corporate working capital as of March 31, 2018 increased by $20 million from December 31, 2017, largely driven by the timing of payments to corporate obligations, including employee compensation, and the impact from our adoption of ASC Topic 606. Refer to Note 1 in Item 1 in this Form 10-Q for details.
Capital Resources
We believe that we can meet our present and reasonably foreseeable operating cash needs and future commitments through existing liquid assets, continuing corporate cash flows from operations, our borrowing capacity under our revolving credit facility and the potential issuance of debt or equity securities under our shelf registration statement on file with the SEC.
We also have available a $75 million revolving credit facility. The total unused portion of the revolving credit facility was $60 million as of March 31, 2018.
Cash Flows
In January 2018, we adopted ASU 2016-18 Statement of Cash Flows (Topic 230): Restricted Cash, which significantly impacted our net cash provided by (used in) operating activities as changes in our restricted cash and cash equivalents balances are no longer included within operating cash activities. For more information about the effects of our adoption of Topic 230, refer to Note 1 in Item 1 in this Form 10-Q.
The following table presents our cash flow activities for the stated periods:

MANAGEMENT'S DISCUSSION AND ANALYSIS |

Operating Activities
Components of net cash used in operating activities are as follows:

| Three Months Ended March 31,
(in millions) | 2018 | 2017
| Corporate | WSE | Total | Corporate | WSE | Total
Net income | $ | 54 |  | $ | — |  | $ | 54 |  | $ | 29 |  | $ | — |  | $ | 29 |

(1) | Prior year balances were retrospectively adjusted for Accounting Standards Update (ASU) 2016-18. Refer to Note 1 in Item 1 of this Form 10-Q for details.

Net cash used in operating activities from WSE-related activities was primarily driven by the timing of client payments, payroll amounts, collateral funding and insurance claim activities. Cash used in operating activities for WSE purposes increased by $344 million during the first quarter of 2018 and was primarily driven by payments of payroll taxes and related liabilities. 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 WSE-related obligations through restricted cash.
Cash provided by corporate operating activities decreased $31 million in the first quarter of 2018 compared to the same period in 2017 and was driven by the timing of payments related to vendors and employee compensation. The overall decrease was partially offset by an 88% increase in our net income.
We expect our tax payments to increase in 2018 due to our inability to defer taxes as a result of new restrictions in the TCJA.
Investing Activities
Net cash used in investing activities in the first quarter of 2018 and 2017 primarily consisted of cash paid for capital expenditures, partially offset by proceeds from the maturity of restricted investments.

| Three Months Ended March 31,
(in millions) | 2018 | 2017
Capital expenditures: |  |
Software and hardware | $ | 6 |  | $ | 6 |
Office furniture, equipment and leasehold improvements | 6 |  | 5 |
Cash used in capital expenditures | $ | 12 |  | $ | 11 |
Investments: |  |
Proceeds from maturity of restricted investments | 14 |  | 4 |
Cash provided by investments | $ | 14 |  | $ | 4 |

During the first quarters of 2018 and 2017, we continued to make investments in software and hardware, enhanced existing products and platforms, and implemented legacy platform migrations. We also incurred expenses related to the build out of our technology and client service centers. We expect capital investments in our software and hardware to continue in the future.

20

MANAGEMENT'S DISCUSSION AND ANALYSIS |

We primarily invest funds held as collateral to satisfy our long-term obligation towards the workers' compensation liabilities in U.S. long-term treasuries. Such investments are classified as available for sale investments and included as restricted cash, cash equivalents and investments in the balance sheet. 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. As of March 31, 2018, we held approximately $855 million in restricted long-term and short-term accounts.
As of March 31, 2018, we held approximately $1.2 billion in cash, cash equivalents and investments. Refer to Note 2 in Item 1 in this Form 10-Q for a summary of these funds.
Financing Activities
Net cash used in financing activities in the first quarter of 2018 and 2017 consisted primarily of repurchases of our common stock and repayment of debt.
Our 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 three months of 2018, we repurchased 160,033 shares of our common stock for approximately $8 million. As of March 31, 2018, approximately $129 million remained available for repurchase under all authorizations by our board of directors.
We will seek to amend the current credit facilities as they expire, as needed by the business or if market conditions become more favorable, although we can provide no assurance that we will be able to do so at interest rates or terms that are as or more favorable than the current interest rates or terms.
Off-Balance Sheet Arrangements
There has been no material change in our off-balance sheet arrangements discussed in Item 7 of our 2017 Form 10-K.
Critical Accounting Policies, Estimates and Judgments
During the three months ended March 31, 2018, we adopted ASC Topic 606. Refer to Note 1 in Item 1 of this Form 10-Q for disclosure of the changes related to this adoption. There have been no additional material changes to our critical accounting policies as discussed in our 2017 Form 10-K.

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 2017 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 March 31, 2018. 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 March 31, 2018, our CEO and CFO concluded that, as of such date, our disclosure controls and procedures were not effective as a result of a material weakness 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 weakness 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 weakness 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 weakness identified by management and described in greater detail in our 2017 Form 10-K. Although we intend to complete the remediation process with respect to this material weakness 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 this material weakness 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 this weakness is 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 material weakness 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 March 31, 2018, 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.

NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS
(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 (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 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 worksite employees (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 (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 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 first quarter of 2018 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, 2017 (2017 Form 10-K).
Reclassifications
Certain prior year amounts have been reclassified to conform to current period presentation. These reclassifications include short-term restricted cash, cash equivalents and investments previously classified as WSE-related assets and now presented within restricted cash, cash equivalents and investments. Refer to the accounting policy below for a description of amounts currently included in restricted cash, cash equivalents, and investments.
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,

26

FINANCIAL STATEMENTS |

• | 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.
Revenue Recognition
On January 1, 2018, we adopted Accounting Standards Codification Topic 606 (ASC Topic 606) using the modified retrospective method applied to those contracts which were not completed as of January 1, 2018. Results for reporting periods beginning after January 1, 2018 are presented under ASC Topic 606, while the comparative prior period amounts are not restated and continue to be reported in accordance with statements previously accounted for under Accounting Standards Codification Topic 605.
Upon adoption of ASC Topic 606, we recorded a $1 million cumulative effect adjustment to opening retained earnings as of January 1, 2018. Impacts from adoption of the new standard on our revenue recognition include:

• | Our annual service contracts with our clients that are cancellable with 30 days' notice are initially considered 30-day contracts under the new standard;

• | Professional service revenues are recognized on an output basis which results in recognition at the time payroll is processed;

• | Our non-refundable set up fees are no longer deferred but accounted for as part of our transaction price and are allocated among professional service revenues and insurance services revenues; and

• | The majority of sales commissions related to onboarding new clients that were previously expensed are capitalized as contract assets and amortized over the estimated customer life.

Accounting Policies under ASC Topic 606 and Nature of Services
Revenues are recognized when control of the promised services are transferred to our clients, in an amount that reflects the consideration that we expect to receive in exchange for services. We generate all of our revenue from contracts with customers. We disaggregate revenues by professional services revenues and insurance services revenues as reported on the condensed consolidated statements of operations and comprehensive income. Generally, both the client and the Company may terminate the contract without penalty by providing a 30-day notice.
Performance Obligations
At contract inception, we assess the services promised in our contracts with customers and identify a performance obligation for each distinct promise to transfer to the customer a service or bundle of services. We determined that the following distinct services represent separate performance obligations:

• | Payroll and payroll tax processing,

• | Health benefits services, and

• | Workers’ compensation services.

Payroll and payroll tax processing performance obligations include services to process payroll and payroll tax-related transactions on behalf of our clients. Revenues associated with this performance obligation are reported as professional service revenues and recognized using an output method in which the control of the promised services is considered transferred when a client's payroll is processed by us and its WSEs are paid. Professional service revenues are stated net of the gross payroll and payroll tax amounts funded by our clients. Although we assume the responsibilities to process and remit the payroll and payroll related obligations, we do not assume employment-related responsibilities such as determining the amount of the payroll and related payroll obligations. As a result, we are considered the agent in this arrangement for revenue recognition purposes.

27

FINANCIAL STATEMENTS |

Health benefits and workers' compensation services include performance obligations to provide TriNet-sponsored health benefits and workers' compensation insurance coverage through insurance policies provided by third-party insurance carriers. Revenues associated with these performance obligations are reported as insurance services revenues and are recognized using the output method over the period of time that the client and WSEs are covered under TriNet-sponsored insurance policies.
As we control the selection of health benefits and workers' compensation coverage made available, insurance services revenues are reported gross since we are considered the principal in this arrangement for revenue recognition purposes. See Item 8 Note 1 in our Form 10-K for further discussion on our accounting policy for insurance costs.
We generally charge new customers a nominal upfront non-refundable fee to recover our costs to set up the client on our TriNet platform for payroll processing and other administrative services, such as benefit enrollments. These fees are accounted for as part of our transaction price and are allocated among the performance obligations based on their relative standalone selling price.
Variable Consideration and Pricing Allocation
Our contracts with customers generally do not include any variable consideration. However, from time to time, we may offer incentive credits to our clients considered to be variable consideration including incentive credits issued related to contract renewals. Incentive credits are recorded as a reduction to revenue as part of the transaction price at contract inception when there is a basis to reasonably estimate the amount of the incentive credit and only to the extent that it is probable that a significant reversal of any incremental revenue will not occur. These incentive credits are allocated among the performance obligations based on their relative standalone selling price.
We allocate the total transaction price to each performance obligation based on the estimated relative standalone selling prices of the promised services underlying each performance obligation. The transaction price for payroll and payroll tax processing performance obligations are determined upon establishment of the contract that contains the final terms of the sale, including the description and price of each service purchased. The estimated service fee is calculated based on observable inputs and include the following key assumptions: target profit margin, pricing strategies including the mix of services purchased and competitive factors, and customer and industry specifics.
The transaction price for health benefits insurance and worker’s compensation insurance performance obligations is determined during the new client on-boarding and enrollment processes based on the types of benefits coverage the clients and WSEs have elected and the applicable risk profile of the client. We estimate our service fees based on actuarial specialists' forecasts of our expected insurance premiums and claim costs, and our proprietary model to develop an amount to cover our costs to administer these programs.
We require our clients to prefund payroll and related taxes and other withholding liabilities before payroll is processed or due for payment. Under the provision of our contracts with customers, we generally will process the payment of a client’s payroll only when the client successfully funds the amount required. Certain contracts to provide payroll and payroll tax processing services permit the client to pay certain payroll tax components ratably over a 12-month period rather than as payroll tax is determined on wages paid, which may be considered a significant financing arrangement under ASC Topic 606. However, as the period between our performing the service under the contract and when the client pays for the service is less than one year, we have elected as a practical expedient, not to adjust the transaction price.
Unbilled Revenue
We recognize WSE payroll and payroll tax liabilities in the period in which the WSEs perform work. When clients' pay
periods cross reporting periods, we accrue the portion of the unpaid WSE payroll where we assume, under state regulations, the obligation for the payment of wages and the corresponding payroll tax liabilities associated with the
work performed prior to period-end. These estimated payroll and payroll taxes liabilities are accrued wages in WSE
related liabilities. The associated receivables, including estimated insurance services revenues, offset by advance collections from clients, are recorded as unbilled revenues in WSE-related assets.

FINANCIAL STATEMENTS |

Contract Costs
We recognize as deferred commission expense the incremental cost to obtain a contract with a client for certain components under our commission plans for sales representatives and channel partners that are directly related to new customers onboarded as we expect to recover these costs through future service fees. Such assets will be amortized over the estimated average client tenure. These commissions are earned on the basis of the revenue generated from payroll and payroll tax processing performance obligations. When the commission on a renewal contract is not commensurate with the commission on the initial contract, such commission will be capitalized and amortized over the estimated average client tenure. If the commission for both initial contract and renewal contracts are commensurate, such commissions are expensed in the contract period. When the amortization period is less than one year, we apply practical expedient to expense sales commissions in sales and marketing expenses in the period incurred. We capitalized $9 million and amortized less than $1 million of the deferred commission during the first quarter 2018.
Certain commission plans will pay a commission on estimated professional service revenues over the first 12 months of the contract with customers. The portion of commission paid in excess of the actual commission earned in that period is recorded as prepaid commission. When the prepaid commission is considered earned, it is classified as a deferred commission expense and subject to amortization.
We do not have material contract assets and contract liabilities as of March 31, 2018. We require our clients to prefund payroll and related liabilities before payroll is processed or due for payment. If a client fails to fund payroll or misses the funding cut-off, at our sole discretion, we may pay the payroll and the resulting unfunded payroll is recognized as accounts receivable on the accompanying consolidated balance sheets. When client payment is received in advance of our performance under the contract, such amount is recorded as client deposits.
Restricted Cash, Cash Equivalents and Investments
Restricted cash and cash equivalents presented on our condensed consolidated balance sheets include:

• | corporate cash and cash equivalents in trust accounts functioning as security deposits for our insurance carriers,

• | payroll funds collected represents cash collected in advance from clients which we designate as restricted for the purpose of funding WSE payroll and payroll taxes and other payroll related liabilities, and

• | amounts held in trust for current and future premium and claim obligations with our insurance carriers, which amounts are held in trust according to the terms of the relevant insurance policies and by the local insurance regulations of the jurisdictions in which the policies are in force.

Recent Accounting Pronouncements
Recently adopted accounting guidance
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.
We have adopted the new standard effective January 1, 2018 using the modified retrospective method. For further discussion of our adoption of ASC Topic 606, including our operating results under the new standard, see Revenue Recognition section above.

FINANCIAL STATEMENTS |

The impact from the adoption of ASC Topic 606 to our condensed consolidated income statements and balance sheets is as follows:

Statement of Cash Flows - In November 2016, the FASB issued ASU No. 2016-18, Statement of Cash Flows (Topic 230): Restricted Cash. ASU 2016-18 addresses diversity in practice from entities classifying and presenting transfers between cash and restricted cash as operating, investing or financing activities or as a combination of those activities in the statement of cash flows. The ASU requires entities to show the changes in the total of cash, cash equivalents, restricted cash and restricted cash equivalents in the Statement of Cash Flows. As a result, transfers between such categories are no longer be presented in the Statement of Cash Flows. We adopted ASU 2016-18 on January 1, 2018 using the retrospective method.
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 continue to assess all potential impacts of the standard, we anticipate that there will be a material increase to assets and lease liabilities for existing property leases representing our nationwide office locations not already included on our condensed consolidated balance sheets.

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 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 and other WSE-related liabilities.
Our total cash, cash equivalents and investments are summarized below:

| March 31, 2018 | December 31, 2017
(in millions) | Cash and cash equivalents | Available for sale marketable securities | Certificate of deposits | Total | Cash and cash equivalents | Available for sale marketable securities | Certificate of deposits | Total

The amortized cost, gross unrealized gains, gross unrealized losses, fair values, and related maturities of securities available for sale as of March 31, 2018 and December 31, 2017 are presented below:

(in millions) | Maturity (in years) | Amortized Cost | Gross Unrealized Gains | Gross Unrealized Losses | Fair Value
March 31, 2018 |  |  |  |  |
U.S. treasuries | 1-5 years | $ | 23 |  | $ | — |  | $ | — |  | $ | 23 |

Exchange traded fund | N/A | 1 |  | — |  | — |  | 1 |
Total |  | $ | 38 |  | $ | — |  | $ | — |  | $ | 38 |

There were immaterial realized gains or losses for the three months ended March 31, 2018 and 2017. The fair value of our U.S. Treasury securities in an unrealized loss position represented 89% and 78% of the total fair value of all U.S. Treasury securities as of March 31, 2018 and December 31, 2017, 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 to hold these available for sale marketable securities until maturity, or for the foreseeable future, no decline was deemed to be other-than-temporary.

The following summarizes workers' compensation liabilities on the condensed consolidated balance sheets:

(in millions) | March 31, 2018 | December 31, 2017
Total loss reserves, end of period | $ | 250 |  | $ | 255 |
Collateral paid to carriers and offset against loss reserves | (21 | ) | (23 | )
Total loss reserves, net of carrier collateral offset | $ | 229 |  | $ | 232 |
Payable in less than 1 year (net of collateral paid to carriers of $5 and $6 at March 31, 2018 and December 31, 2017, respectively) | $ | 67 |  | $ | 67 |
Payable in more than 1 year (net of collateral paid to carriers of $16 and $17 at March 31, 2018 and December 31, 2017, respectively) | 162 |  | 165 |
Total loss reserves, net of carrier collateral offset | $ | 229 |  | $ | 232 |

Incurred claims related to prior years represent changes in estimates for ultimate losses on workers' compensation claims. For the three months ended March 31, 2018, the favorable development was primarily due to lower than expected severity of reported claims associated with office and non-office worker WSEs in recent accident years.
As of March 31, 2018 and December 31, 2017, we had $61 million and $63 million, respectively, of collateral held by insurance carriers of which $21 million and $23 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 is recorded as workers' compensation collateral receivable.

Total restricted investments | 38 |  | 2 |  | 40 |
Total restricted cash equivalents and investments | $ | 258 |  | $ | 2 |  | $ | 260 |

Restricted Cash Equivalents
Our restricted cash equivalents include money market mutual funds and commercial paper. The carrying value of cash equivalents approximate their fair values due to the short-term maturities and are classified as Level 1 in the fair value hierarchy because we use quoted market prices that are readily available in an active market to determine the fair value.
Restricted Investments
Our restricted investments include U.S. Treasuries, an exchange traded fund and a certificate of deposit. The U.S. Treasuries and exchange traded fund are classified as Level 1 securities in the fair value hierarchy as we use active quoted market prices that are readily available in an active market to determine fair value. The certificate of deposit is classified as Level 2 in the fair value hierarchy as we use a market approach that compares the fair values on certificates with similar maturities.
We did not have any Level 3 financial instruments as of March 31, 2018 and December 31, 2017. There were no transfers between levels as of March 31, 2018 and December 31, 2017.

FINANCIAL STATEMENTS |

Fair Value of Financial Instruments Disclosures
Notes Payable
The carrying value of our notes payable at March 31, 2018 and December 31, 2017 was $415 million and $425 million, respectively. The estimated fair values of our notes payable at March 31, 2018 and December 31, 2017 were $418 million and $428 million, respectively. These valuations are considered Level 2 in the hierarchy for fair value measurement and are based on quoted market prices.
NOTE 5. STOCKHOLDERS’ EQUITY
Equity-Based Incentive Plans
Our 2009 Equity Incentive Plan (2009 Plan) provides for the grant of stock awards, including stock options, restricted stock units (time-based and performance-based), restricted stock awards (time-based and performance-based) and other equity awards. The number of shares available for grant under this 2009 Plan as of March 31, 2018 was approximately 11 million.
The following table summarizes stock option activity under our 2009 Plan for the three months ended March 31, 2018:

| Number of Shares
Balance at December 31, 2017 | 1,296,863 |
Exercised | (206,430 | )
Forfeited | (4,167 | )
Balance at March 31, 2018 | 1,086,266 |
Exercisable at March 31, 2018 | 1,011,038 |

The aggregate intrinsic value of stock options outstanding was $37 million and $41 million as of March 31, 2018 and December 31, 2017, respectively.
In March 2018, the Equity Award Committee of the Compensation Committee granted awards of time-based restricted stock (RSAs) and performance-based restricted stock (PRSAs) to the Company's named executive officers (as defined in Item 402(a)(3) of Regulation S-K promulgated by the Securities and Exchange Commission). A recipient of RSAs owns the underlying shares of common stock upon grant and some of the benefits of ownership, such as voting and dividend rights, but the recipient may not sell those shares and realize any value on a sale, until all time-based and performance-based restrictions have been satisfied or lapsed.
Our RSAs granted in March 2018 are eligible to vest in equal installments on a quarterly basis over four years, subject to continued employment through the applicable vesting dates. The PRSAs are earned based on the extent to which the Company meets or exceeds certain annual growth rate percentages. Our PRSAs granted in March 2018 are designed with a single-year performance period subject to subsequent multi-year vesting requirements. Fifty percent of the shares earned (if any) during performance period (January 1, 2018 to December 31, 2018) will vest on December 31, 2019 and the remaining shares earned (if any) will vest on December 31, 2020.

Stock-Based Compensation
Stock-based compensation expense is measured based on the fair value of the stock option on the grant date and recognized over the requisite service period for each separately vesting portion of the stock option award. Stock-based compensation expense and other disclosures for stock-based awards made to our employees pursuant to the equity plans was as follows:

Stock Repurchases
The board of directors authorizes repurchases through an ongoing program initiated in May 2014. During the three months ended March 31, 2018, we repurchased 160,033 shares of common stock for approximately $8 million. As of March 31, 2018, approximately $129 million remained available for further repurchases of our common stock under our ongoing stock repurchase program under all authorizations from our board of directors.

Common stock equivalents excluded from income per diluted share because of their anti-dilutive effect | 1 |  | 1 |

NOTE 7. INCOME TAXES
Our effective income tax rate was 20% and 36% for the three months ended March 31, 2018 and 2017, respectively. The decrease was primarily attributable to a reduction of the federal corporate income tax rate from 35% to 21% on January 1, 2018 under the Tax Cuts and Jobs Act (TCJA). The decrease is also attributable to changes to uncertain income tax positions arising from state tax exposures recorded in the same period of 2017. The remaining impacts consisted of tax benefits recognized from excess tax benefits related to stock-based compensation and an increase in excludable income for state income tax purposes.
During the three months ended March 31, 2018, there was a de minimis increase in our unrecognized tax benefits. The total amount of gross interest and penalties accrued was immaterial. 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 $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. This issue is being resolved through the litigation process. Currently, we anticipate our recovery of the refund to likely be less than the total amount.
NOTE 8. COMMITMENTS AND CONTINGENCIES
Lease Commitments
We lease office facilities, including our headquarters and other facilities, and equipment under non-cancellable operating leases. For detail of these commitments refer to Note 13 in Part II, Item 8 in our 2017 Form 10-K.
Credit Facilities
We maintain a $75 million revolving credit facility which includes capacity for a $40 million letter of credit facility and a $10 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 $60 million as of March 31, 2018.
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 covenants at March 31, 2018.

36

FINANCIAL STATEMENTS |

We also have a $5 million line of credit facility to secure standby letters of credit related to our workers' compensation obligations. At March 31, 2018, the total unused portion of the credit facility was $3 million.
Standby Letters of Credit
We have two standby letters of credit totaling $18 million provided as collateral for our workers’ compensation obligations. At March 31, 2018, the facilities were not drawn down.
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 for the Northern District of California. The complaint was later amended in April 2016 and again in March 2017. On December 19, 2017, the district court granted TriNet’s motion to dismiss the amended complaint in its entirety, without leave to amend. Plaintiff filed a notice of appeal of the district court’s order on January 17, 2018. Plaintiff-Appellant filed his opening appeal brief before the Ninth Circuit Court of Appeals on April 27, 2018. TriNet intends to file a responsive brief by May 29, 2018. We will defend the appeal of the district court’s decision vigorously as we see no basis for reversal. We are unable to reasonably estimate the possible loss or expense, or range of losses and expenses, 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 its 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 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.

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 2017 Form 10-K.
