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 HR expertise, payroll services, employee benefits and employment risk mitigation services for SMBs. We deliver a comprehensive suite of products and services, which allows our clients to administer and manage various HR-related functions, including compensation and benefits, payroll processing, employee data, health insurance and workers' compensation programs, and other transactional HR needs using our technology platform and HR, benefits and compliance expertise.

We also leverage our scale and industry-specific HR experience to design product and service offerings for SMBs in specific industries. We believe our industry-specific approach, which we call our vertical approach, is a key differentiator for us and creates additional value for our clients by allowing our product and service offerings to address the common HR needs in different client industries.

Operational Highlights

Our consolidated results for the third quarter and nine months ended September 30, 2019 reflect our continued progress in attracting new customers to our industry-oriented (vertical) products, serving our existing customers and improving our brand awareness through marketing.

Our customers are our focus, and we are investing in our processes to ensure a stronger customer experience. We expect this investment will further enhance our value to our customers, support retention and provide further efficiency and scale for our operations. We started this work in 2018 and expect this to continue in the near-term.

During the nine months ended September 30, 2019 we:

• experienced an improvement in retention as a result of our customer service initiatives,

• benefited from our clients growing their WSEs,

• saw an increase in new sales, which delivered additional revenue growth,

• continued to experience our WSE's increasing their participation, or enrollment, in our insurance services offerings,

• experienced increased severity of health costs per enrollee (medical cost trend) within a national carrier, and

• delivered profitable growth.

Our efforts to build a successful and enduring company include building and leveraging a strong national brand presence. Our branding strategy, Incredible Starts Here, is being augmented with our current campaign: People Matter. We place our customers at the center of what we do, including placing our customers at the center of our marketing.

MANAGEMENT'S DISCUSSION AND ANALYSIS

Performance Highlights

Our results for the third quarter and nine months ended September 30, 2019 are as follows (percentages, increases or decreases represent changes when compared to the same periods of 2018):

Q3 2019

	$969M			$68M			$221M
	Total revenues			Operating income			Net Service Revenue *
	11	%	increase	9	%	increase	(4	)%	decrease
	$55M			$0.78			$58M
	Net income			Diluted EPS			Adjusted Net income *

331,584			330,970			$9.4B
Total WSEs			Average WSEs			Payroll and payroll tax payments
4	%	increase	4	%	increase	8	%	increase

During the third quarter of 2019, we continued to achieve year-over-year improvement in our WSE and revenue growth. The growth year-over-year reflects improvement in our new sales performance and the retention of customers that choose to benefit from our service offerings. Increased hiring and enrollments by our customers contributed to the growth. We continue to price to the value of our services and, for our insurance offerings, to our expected risk. Operating income, net income and adjusted net income increased due primarily to a 11% increase in total revenues and a decrease in operating expenses primarily as a result of lower variable incentive compensation reflecting financial performance, offset by higher insurance costs driven by an increase in medical cost trend and health plan participation or enrollment. Net Service Revenue decreased 4% primarily due to medical cost trend within a national carrier.

Average WSEs (defined as average monthly WSEs paid during the period) for the third quarter of 2019 increased 4% compared to the same period in 2018 driven by lower client attrition in our Main Street vertical, improved new sales and increased WSE hiring by our clients.

Our pricing strategy and change in mix of WSEs over the last year contributed to our growth of both PSR and ISR.

Non-GAAP Financial Measures

In addition to financial measures presented in accordance with GAAP, we monitor other non-GAAP financial measures that we use to manage our business, to make planning decisions, to allocate resources, and to use as performance measures in our executive compensation plan. These key financial measures provide an additional view of our operational performance over the long-term and provide information that we use 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. They are not meant to be considered in isolation from, superior to, or as a substitute, for the directly comparable financial measures prepared in accordance with GAAP.

7

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 presented net of client payroll costs whereas insurance service revenues are presented gross of insurance costs for financial reporting purposes. • Acts as the basis to allocate resources to different functions and evaluates the effectiveness of our business strategies by each business function. • Provides a measure, among others, used in the determination of incentive compensation for management.
Net Insurance Service Revenues	• Insurance revenues less insurance costs.	• Is a component of Net Service Revenues. • Provides a comparable basis of revenues on a net basis. Professional service revenues are presented net of client payroll costs whereas insurance service revenues are presented gross of insurance costs for financial reporting purposes. Promotes an understanding of our insurance services business by evaluating insurance service revenues net of our WSE related costs which are substantially pass-through for the benefit of our WSEs. Under GAAP, insurance service revenues and costs are recorded gross as we have latitude in establishing the price, service and supplier specifications. • We also sometimes refer to Net Insurance Service Margin, which is the ratio of Net Insurance Revenue to Insurance Service Revenue.
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 either not directly resulting from our core operations or not indicative of our ongoing operations. • Enhances comparisons to prior periods and, accordingly, facilitates the development of future projections and earnings growth prospects. • Provides a measure, among others, used in the determination of incentive compensation for management. • We also sometimes refer to Adjusted EBITDA margin, which is the ratio of Adjusted EBITDA to Net Service Revenue.
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.

MANAGEMENT'S DISCUSSION AND ANALYSIS

Corporate Operating Cash Flows • Net cash (used in) provided by operating activities, excluding the effects of: - Assets associated with WSEs (accounts receivable, unbilled revenue, prepaid expenses and other current assets) and - Liabilities associated with WSEs (client deposits, accrued wages, payroll tax liabilities and other payroll withholdings, accrued health benefit costs, accrued workers' compensation costs, insurance premiums and other payables, and other current liabilities). • Provides information that our stockholders and management can use to evaluate our cash flows from operations independent of the current assets and liabilities associated with our WSEs.
• Enhances comparisons to prior periods and, accordingly, used as a liquidity measure to manage liquidity between corporate and WSE related activities, and to help determine and plan our cash flow and capital strategies.

(1) Non-GAAP effective tax rate is 26% for 2019 and 2018, which excludes 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 WSEs increased 4% in the third quarter of 2019 and 2% in the nine months ended September 30, 2019, compared to the same periods in 2018, due to reduced attrition resulting from our customer service initiatives, continued hiring within our installed base, primarily in our Technology vertical, and stronger new sales performance.

Total WSEs can be used to estimate our beginning WSEs for the next period and, as a result, can be used as an indicator of our potential future success in growing our business and retaining clients.

Anticipated revenues for future periods can diverge from the revenue expectation derived from Average WSEs or Total WSEs due to pricing differences across our HR solutions and services and the degree to which clients and WSEs elect to participate in our solutions during future periods. In addition to focusing on growing our Average WSE and Total WSE counts, we also focus on pricing strategies, product participation and product differentiation to expand our revenue opportunities. We report the impact of client and WSE participation differences as a change in mix.

We are focused on growing our WSE base, including pursuing strategic acquisitions where appropriate, while improving our customer experience and continuing to manage attrition. We continued to invest in our efforts to enhance our customers' and WSEs' experiences, through operational and process improvements, and we have started to realize improved retention in some of our verticals.

11

MANAGEMENT'S DISCUSSION AND ANALYSIS

Total Revenues

Our revenues consist of professional service revenues (PSR) and insurance service revenues (ISR). PSR represents fees charged to clients for processing payroll-related transactions on behalf of our clients, access to our HR expertise, employment and benefit law compliance services, and other HR-related services. ISR consists of insurance-related billings and administrative fees collected from clients and withheld from WSEs for workers' compensation insurance and health benefit insurance plans provided by third-party insurance carriers.

Monthly total revenues per Average WSE is a measure we use to monitor the success of our product and service pricing strategies. This measure increased 6% during the third quarter of 2019 compared to the same period in 2018, and increased 8% in the nine months ended September 30, 2019, compared to the same period in 2018.

We also analyze changes in total revenue with the following measures:

• Volume - the percentage change in period over period Average WSEs,

• Rate - the combined percentage change in service fees for each vertical product and change in service fees associated with each insurance service offerings, and

• Mix - the change in composition of Average WSEs within our verticals combined with the composition of our enrolled WSEs within our insurance service offerings.

The changes in volume during the third quarter and nine months ended September 30, 2019, when compared to the same periods in 2018, were primarily driven by WSE growth, especially in our Professional Services and Technology verticals. The changes in rate and mix during the third quarter and nine months ended September 30, 2019, when compared to the same periods in 2018, were primarily driven by increases in insurance services fees and health plan enrollment in our insurance service offerings.

12

MANAGEMENT'S DISCUSSION AND ANALYSIS

Operating Income

Our operating income consists of total revenues less insurance costs and OE. Our insurance costs include insurance premiums for coverage provided by insurance carriers, reimbursement of claims payments made by insurance carriers or third-party administrators, and changes in accrued costs related to contractual obligations with our workers' compensation and health benefit carriers. Our OE consists primarily of our corporate employees' compensation related expenses which includes payroll, payroll taxes, SBC, bonuses, commissions and other payroll-and benefits-related costs.

The tables below provide a view of the changes in components of operating income for the third quarter and nine months ended September 30, 2019, as compared to the same periods in 2018, respectively.

(in millions)
$62		Third Quarter 2018 Operating Income
	+94	Higher total revenues primarily as a result of WSE growth, especially in our Professional Services and Technology verticals, increases in ISR fees and health plan enrollment.
	-101	Higher insurance costs primarily as a result of an increase in medical cost trend and health plan participation, or enrollment.
	+13	Lower OE primarily as a result of lower variable incentive compensation reflecting financial performance.
$68		Third Quarter 2019 Operating Income

(in millions)
$209		YTD 2018 Operating Income
	+252	Higher total revenues primarily as a result of increases in insurance services fees and health plan enrollment in our insurance service offerings
	-217	Higher insurance costs primarily as a result of an increase in medical cost trend and health plan participation, or enrollment.
	-39	Higher OE primarily as a result of growth in the number of our corporate employees and costs associated with initiatives to improve customer experience and our growth initiatives.
$205		YTD 2019 Operating Income

MANAGEMENT'S DISCUSSION AND ANALYSIS

Professional Service Revenues

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 increase, our fees also increase. As such, payroll and payroll taxes processed, which includes recurring payrolls and non-recurring bonus payrolls, benefits, and associated payroll taxes may also be an indicator of our PSR growth.

Our vertical approach provides us the flexibility to offer our clients in different industries with varied services at different prices, which we believe potentially reduces the value of using Average WSE and Total WSE counts as indicators of future potential revenue performance.

We also analyze changes in PSR with the following measures:

• Volume - the percentage change in period over period Average WSEs.

• Rate - the percentage change in fees for each vertical, and

• Mix - the change in composition of Average WSEs across our verticals,

The increase in PSR, for the third quarter ended and nine months ended September 30, 2019 compared to the same periods in 2018, reflects the result of our vertical pricing strategy. During the third quarter and nine months ended September 30, 2019, we continued to experience WSE growth especially in our Professional Services and Technology verticals, while our Main Street vertical continued to shrink, but at a reduced rate when compared to the same periods in 2018.

14

MANAGEMENT'S DISCUSSION AND ANALYSIS

Insurance Service Revenues

ISR consists of insurance services-related billings and administrative fees collected from clients and withheld from WSE payroll for health benefits and workers' compensation insurance provided by third-party insurance carriers.

We use the following measures to analyze changes in ISR:

• Volume - the percentage change in period over period Average WSEs,

• Rate - the percentage change in fees associated with each of our insurance service offerings, and

• Mix - all other changes including the composition of our enrolled WSEs within our insurance service offerings (health plan enrollment).

The growth in ISR for the third quarter and nine months ended September 30, 2019, as compared to the same periods in 2018, primarily resulted from increases in Average WSEs, changes in rate due to higher insurance service fees per plan participant and changes in mix due to higher health plan enrollment.

15

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 accrued costs related to contractual obligations with our workers' compensation and health benefit carriers.

We use the following measures to analyze changes in insurance costs:

• Volume - the percentage change in period over period Average WSEs,

• Rate - the percentage change in cost trend associated with each of our insurance service offerings, and

• Mix - all other changes including the composition of our enrolled WSEs within our insurance service offerings (health plan enrollment).

The increase in insurance cost rates during the third quarter and nine months ended September 30, 2019, as compared to the same periods in 2018, was primarily driven by:

• Increased severity of health costs per enrollee (medical cost trend) within a national carrier, arising from a shift in pharmaceutical utilization from brand name drugs to higher cost specialty drugs, combined with elevated health costs in a portion of this business.

• Partially offset by lower health administrative costs and lower workers' compensation claim costs.

We continued to experience favorable prior year development on our accrued workers' compensation costs of $6 million for the third quarter and $22 million for the nine months ended September 30, 2019, primarily due to lower than expected claim severity. The increase in volume and mix during the third quarter and nine months ended September 30, 2019 is consistent with the change in volume and mix for ISR, which was a result of higher health plan enrollment.

16

MANAGEMENT'S DISCUSSION AND ANALYSIS

Net Service Revenues

NSR provides us with a comparable basis of revenues on a net basis, acts as the basis to allocate resources to different functions and helps us evaluate the effectiveness of our business strategies by each business function.

NISR margin for the third quarter and nine months ended September 30, 2019 decreased by 3% and 1%, respectively when compared to the same periods in 2018, due to insurance costs increasing faster than insurance service revenues.

17

MANAGEMENT'S DISCUSSION AND ANALYSIS

Operating Expenses

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

We manage our operating expenses and allocate resources across different business functions based on percentage of NSR, which decreased to 69% in the third quarter of 2019 from 73% in the same period in 2018 and increased to 71% in the nine months ended September 30, 2019 from 69% in the same period in 2018. The decrease in operating expenses and compensation costs was primarily the result of lower variable incentive compensation reflecting financial performance.

We had approximately 3,000 corporate employees as of September 30, 2019 in 54 offices across the U.S. Our corporate employees' compensation-related expenses represent a majority of our OE. Compensation costs for our corporate employees include payroll, payroll taxes, SBC, bonuses, commissions and other payroll- and benefits-related costs. Compensation expense for internal employees was and is primarily driven by our continued efforts to improve our customer experience. Compensation-related expense represented 59% and 62% of our OE in the third quarter of 2019 and 2018, respectively, and 62% and 63% in the nine months ended September 30, 2019 and 2018, respectively.

We expect our OE to increase for the foreseeable future from our continued efforts to improve our customer experience, and our systems and processes. These expenses may fluctuate as a percentage of our total revenues from period-to-period depending on the timing of when expenses are incurred.

18

MANAGEMENT'S DISCUSSION AND ANALYSIS

We analyze and present our OE based upon the business functions COPS, S&M, G&A and SD&P and D&A. The charts below provide a view of the expenses of the business functions. Dollars are presented in millions and percentages represent year-over-year change.

COPS remained consistent in the third quarter of 2019 when compared to the same period in 2018. The increase in the nine months ended September 30, 2019, when compared to the same periods in 2018, was due to increased headcount and consulting expense to support initiatives to improve the customer experience, enhancing our product offerings and process improvement initiatives.

S&M decreased in the third quarter of 2019, when compared to the same period in 2018, primarily due to a decrease in compensation related expenses. S&M increased in the nine months ended September 30, 2019, when compared to the same period in 2018, driven by an increase in headcount, advertising expenses for our People Matter campaign and commissions expense related to our growth in new sales.

G&A decreased in the third quarter and increased in the nine months ended September 30, 2019, when compared to the same periods in 2018, primarily driven by a decrease in compensation related expenses and professional fees.

SD&P decreased in the third quarter and nine months ended September 30, 2019, when compared to the same periods in 2018, primarily driven by a decrease in compensation related expenses.

D&A remained consistent in the third quarter. The increase in the nine months ended September 30, 2019, when compared to the same periods in 2018, was a result of our investments in technology to support our customer service initiatives.

19

MANAGEMENT'S DISCUSSION AND ANALYSIS

We break out the change in expenses that make up our OE in the chart below:

Other Income (Expense)

Other income (expense) consists primarily of interest and dividend income from investments and interest expense under our credit facility.

Interest income increased to $5 million in the third quarter of 2019 and $18 million for the nine months ended September 30, 2019 from $3 million and $7 million when compared to the same periods in 2018, respectively, as a result of a change in our investment strategy initiated in the second quarter of 2018 to improve our interest income.

Our investment strategy has improved our interest income, net income, Adjusted Net Income and Adjusted EBITDA, year over year.

Interest expense, bank fees and other, remained consistent for the third quarter and nine months ended September 30, 2019 and 2018.

20

MANAGEMENT'S DISCUSSION AND ANALYSIS

Provision for Income Taxes

Our effective income tax rate was 18% and 16% for the third quarter of 2019 and 2018, respectively, and 20% and 18% for the nine months ended September 30, 2019 and 2018, respectively. The increase in rate for the third quarter of 2019 was primarily due to a decrease in tax credits and a benefit from revaluation of deferred taxes recorded in the prior year. The increase in rate for the nine months ended September 30, 2019 was primarily due to decreases in excludable income for state tax purposes and tax benefits recognized from excess tax benefits related to stock based compensation, as well as an increase in uncertain tax positions. These expenses are partially offset by a one-time benefit associated with prior year tax expense.

21

MANAGEMENT'S DISCUSSION AND ANALYSIS

Liquidity and Capital Resources

Liquidity

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

Included in our balance sheets are assets and liabilities resulting from transactions directly or indirectly associated with WSEs, including payroll and related taxes and withholdings, our sponsored workers' compensation and health insurance programs, and other benefit programs. Although we are not subject to regulatory restrictions that require us to do so, we distinguish and manage our corporate assets and liabilities separately from those current assets and liabilities held by us to satisfy our employer obligations associated with our WSEs as follows:

	September 30, 2019						December 31, 2018
(in millions)	Corporate		WSE		Total		Corporate		WSE		Total
Current assets:
Cash and cash equivalents	$	216	$	—	$	216	$	228	$	—	$	228
Investments	67		—		67		54		—		54
Restricted cash, cash equivalents and investments	15		570		585		15		927		942
Other current assets	56		451		507		36		386		422
Total current assets	$	354	$	1,021	$	1,375	$	333	$	1,313	$	1,646
Total current liabilities	$	101	$	1,021	$	1,122	$	112	$	1,313	$	1,425
Working Capital	$	253	$	—	$	253	$	221	$	—	$	221

Working capital for WSE-related assets and liabilities

We designate funds to ensure that we have adequate current assets to satisfy our current obligations associated with WSEs. We manage our WSE payroll and benefits obligations through collections of payments from our clients which generally occurs two to three days in advance of client payroll dates. We regularly review our short-term obligations associated with our WSEs (such as payroll and related taxes, insurance premium and claim payments) and designate funds required to fulfill these short-term obligations, which we refer to as PFC. PFC is included in current assets as restricted cash, cash equivalents and investments.

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

Working capital for corporate purposes

We use our available cash and cash equivalents 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 September 30, 2019 increased compared to December 31, 2018.

Capital Resources

Sources of Funds

We believe that we can meet our present and reasonably foreseeable operating cash needs and future commitments through existing liquid assets, continuing cash flows from corporate operating activities, our borrowing capacity under our revolving credit facility and the potential issuance of debt or equity securities.

22

MANAGEMENT'S DISCUSSION AND ANALYSIS

We also have available a $250 million revolving credit facility. The total unused portion of the revolving credit facility was $235 million as of September 30, 2019.

Cash Flows

The following table presents our cash flow activities for the stated periods:

	Nine Months Ended September 30,
(in millions)	2019									2018
	Corporate			WSE			Total			Corporate			WSE			Total
Net cash (used in) provided by :

Operating Activities

Components of net cash (used in) provided by operating activities are as follows:

	Nine Months Ended September 30,
(in millions)	2019									2018
	Corporate			WSE			Total			Corporate			WSE			Total
Net income	$	164		$	—		$	164		$	163		$	—		$	163

Changes in other operating assets	(42		)	(65		)	(107		)	10			(51		)	(41		)
Changes in other operating liabilities	3			(292		)	(289		)	(9		)	(609		)	(618		)
Net cash (used in) provided by operating activities	$	146		$	(357	)	$	(211	)	$	184		$	(660	)	$	(476	)

Year-over-year fluctuation in net cash used in operating activities for WSE purposes was primarily driven by timing of client payments, payments of payroll and payroll taxes, and collateral funding and insurance claim activities. We expect the changes in restricted cash and cash equivalents to correspond to WSE cash provided by (or used in) operations as we manage our obligations associated with WSEs through restricted cash.

Our corporate operating cash flows decreased when comparing the nine months ended September 30, 2019 to the same period in 2018 due to timing of payments to our vendors.

23

MANAGEMENT'S DISCUSSION AND ANALYSIS

Investing Activities

Net cash (used in) provided by investing activities in the nine months ended September 30, 2019 decreased, when compared to the same period of 2018, primarily due to decrease in purchases of investments.

	Nine Months Ended September 30,
(in millions)	2019			2018
Investments:
Purchases of investments	(109		)	(223		)
Proceeds from sale and maturity of investments	113			87
Cash (used in) provided by investments	$	4		$	(136	)
Capital expenditures:

Cash used in capital expenditures	$	(34	)	$	(33	)
Cash used in investing activities	$	(30	)	$	(169	)

Investments

We invest a portion of available cash in investment-grade securities with effective maturities less than five years that are classified on our condensed consolidated balance sheets as investments. As of September 30, 2019, we had approximately $195 million in corporate investments.

We also invest funds held as collateral to satisfy our long-term obligation towards workers' compensation liabilities in U.S. long-term treasuries. These investments are classified on our condensed consolidated balance sheets as restricted cash, cash equivalents and investments. We review the amount and the anticipated holding period of these investments regularly in conjunction with our estimated long-term workers' compensation liabilities and anticipated claims payment trend.

As of September 30, 2019, we held approximately $1.2 billion in cash, cash equivalents and investments of which $0.8 billion was restricted. Refer to Note 2 in this Form 10-Q for a summary of these funds.

Capital Expenditures

During the nine months ended September 30, 2019 and 2018, we continued to make investments in software and hardware, and to enhance our existing products and technology platform. We also incurred expenses related to the build out of our corporate headquarters and our technology and client service centers. We expect capital investments in our software and hardware to continue in the future.

Financing Activities

Net cash used in financing activities in the nine months ended September 30, 2019 and 2018 consisted of our debt and equity-related activities.

	Nine Months Ended September 30,
(in millions)	2019			2018

24

MANAGEMENT'S DISCUSSION AND ANALYSIS

In February 2019, our board of directors authorized a $300 million incremental increase to our ongoing stock repurchase program initiated in May 2014, primarily to return value to our stockholders and to offset dilution from the issuance of stock under our equity-based incentive plan and employee stock purchase plan. During the nine months ended September 30, 2019, we repurchased 1,482,655 shares of our common stock for approximately $84 million through our stock repurchase program. As of September 30, 2019, approximately $292 million remained available for repurchase under all authorizations by our board of directors. We plan to use current cash and cash generated from ongoing operating activities to fund this share repurchase program.

Covenants

We were in compliance with the financial covenants under our credit facilities at September 30, 2019. For information on the covenants under our 2018 credit facility, refer to Note 7 in Part II, Item 8. Financial Statements and Supplementary Data, of our Form 10-K.

Off-Balance Sheet Arrangements

There have been no additional material changes in our off-balance sheet arrangements discussed in Part II, Item 7. Management's Discussion and Analysis of our 2018 Form 10-K.

Critical Accounting Policies, Estimates and Judgments

During the first quarter of 2019, we adopted ASC Topic 842. 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 material changes to our critical accounting policies as discussed in our 2018 Form 10-K.

QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

AND CONTROLS AND PROCEDURES

Quantitative and Qualitative Disclosures About Market Risk

Our exposure to changes in interest rates relates primarily to our investment portfolio and outstanding floating rate debt. Changes in U.S. interest rates affect the interest earned on the Company’s cash, cash equivalents and investments and the fair value of the investments, as well as interest costs associated with our debt.

On June 2019, we entered into an interest rate collar derivative transaction with no upfront premium. We use this derivative to hedge against interest rate risk on a portion of our outstanding floating rate debt. We have designated this derivative as a cash flow hedge. Our primary objective in purchasing and holding this derivative is to reduce our volatility of net earnings and cash flows associated with changes in the benchmark interest rate in our interest rate payments. We do not enter into any derivatives for trading or other speculative purposes.

We performed a sensitivity analysis to determine the impact a change in interest rates would have on the cash flows of the collar assuming a 100 basis point parallel shift in the current LIBOR rate. Based on the terms and remaining settlements as of September 30, 2019, a hypothetical 100 basis point decrease in one-month LIBOR across all maturities would not result in any cash payments or cash receipts by the Company, respectively, while a hypothetical 100 basis point increase in one-month LIBOR across all maturities would result in cash receipts of $4 million.

Our cash equivalents consist primarily of money market mutual funds, which are not significantly exposed to interest rate risk. Our AFS marketable securities are subject to interest rate risk because these securities generally include a fixed interest rate. As a result, the market values of these securities are affected by changes in prevailing interest rates. We attempt to limit our exposure to interest rate risk and credit risk, as our investment policy defines minimum credit quality, liquidity, diversification and other requirements for eligible investments. Our AFS marketable securities consist of highly liquid, investment-grade securities. The risk of rate changes on investment balances was not significant at September 30, 2019.

At September 30, 2019, we had total outstanding long-term debt of $397 million. A 100 basis point increase or decrease in market interest rates would cause interest expense on our debt as of September 30, 2019 to increase by $10 million or decrease by $14 million on an annualized basis, respectively.

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 September 30, 2019, as defined in Rules 13a-15(e) and 15d-15(e) under the Securities Exchange Act of 1934, as amended, or the Exchange Act.

Based on the evaluation of our disclosure controls and procedures as of September 30, 2019, our CEO and CFO have concluded that the Company’s disclosure controls and procedures were effective as of such date in ensuring that (i) information required to be disclosed by the Company in reports that it files or submits under the Exchange Act is accumulated and communicated to the Company’s management, including the CEO and CFO, to allow timely decisions regarding required disclosure and (ii) such information is recorded, processed, summarized and reported within the time periods specified in the SEC rules and forms.

We have concluded that the condensed consolidated financial statements included in this Quarterly Report on Form 10-Q fairly present, in all material respects, our financial position, results of operations and cash flows for the periods presented in conformity with GAAP.

Changes in Internal Control Over Financial Reporting

There were no changes in our internal control over financial reporting identified in connection with the evaluation required by Rule 13a-15(d) and 15d-15(d) of the Exchange Act that occurred during the quarter ended September 30, 2019, 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.

FINANCIAL STATEMENTS

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 (accrued workers' compensation costs) related to workers' compensation and workers' compensation collateral receivable,

• accrued health insurance costs,

• liability for insurance premiums payable,

• valuation of the investment portfolio,

• 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.

Accrued Health Insurance Costs

We sponsor and administer a number of fully insured, risk-based employee benefit plans, including group health, dental, and vision as an employer plan sponsor under section 3(5) of the ERISA. In the nine months ended September 30, 2019, the majority of our group health insurance costs related to risk-based plans. Our remaining group health insurance costs were for guaranteed-cost policies.

Accrued health insurance costs are established to provide for the estimated unpaid costs of reimbursing the carriers for paying claims within the deductible layer in accordance with risk-based health insurance policies. These accrued costs include estimates for reported losses, plus estimates for claims incurred but not paid. We assess accrued health insurance costs regularly based upon independent actuarial studies that include other relevant factors such as current and historical claims payment patterns, plan enrollment and medical trend rates.

In certain carrier contracts we are required to prepay the expected claims activity for subsequent periods. These prepaid balances by agreement permit net settlement of obligations and offset the accrued health insurance costs. As of September 30, 2019 and December 31, 2018, prepayments included in accrued health insurance costs were $39 million and $33 million, respectively. When the prepaid is in excess of our recorded liability, the net asset position is included in prepaid expenses. As of September 30, 2019 and December 31, 2018, accrued health insurance costs included in prepaid expenses were $53 million and $50 million, respectively.

Derivative Instruments

In June 2019, we entered into an interest rate collar derivative transaction with no upfront premium to mitigate the risk of changes in interest rates on our floating rate debt. This derivative, for which we have elected and qualify for cash flow hedge accounting, is recorded on the balance sheet at its fair value. Changes in the derivative’s fair value are recorded each period in other comprehensive income until the underlying monthly interest payment and the corresponding portion of the derivative are settled, at which point changes in fair value are recorded in net income. We evaluate this derivative each quarter to determine that it remains effective by comparing the remaining expected cash flows of the derivative against the related expected interest payments of our floating rate debt. We do not enter into any derivatives for trading or other speculative purposes.

Leases

We adopted ASU 2016-02 - Leases (ASC 842) effective January 1, 2019 using the optional transition method, under which we recognized the cumulative effects of initially applying the standard as an adjustment to the opening balance of retained earnings on January 1, 2019 with unchanged comparative periods. As part of this adoption, we elected the following practical expedients:

• not to reassess 1) whether any contracts that existed prior to adoption have or contain leases, 2) the classification of our existing leases or 3) initial direct costs for existing leases,

33

FINANCIAL STATEMENTS

• to use the practical expedient of using hindsight to determine the lease terms and evaluate any impairments in right-of-use assets upon transition, and

• not separately record non-lease and lease components for all leases in which we act as a lessee.

We determine if a new contractual arrangement is a lease at contract inception. If a contract contains a lease, we evaluate whether it should be classified as an operating or a finance lease. If applicable as a lease, we record our lease liabilities and ROU assets based on the future minimum lease payments over the lease term and only include options to renew a lease in the future minimum lease payments if it is reasonably certain that we will exercise that option. For certain leases with original terms of twelve months or less we recognize the lease expense as incurred and we do not recognize lease liabilities and ROU assets.

We measure our lease liabilities based on the future minimum lease payments discounted over the lease term. We determine our discount rate at lease inception using our incremental borrowing rate, which is based on our outstanding term debts that are collateralized by certain corporate assets. As of September 30, 2019, the weighted-average rate used in discounting the lease liability was 4%.

We measure our ROU assets based on the associated lease liabilities adjusted for any lease incentives such as tenant improvement allowances and classify operating ROU assets in other assets in our condensed consolidated balance sheet. For operating leases, we recognize expense for lease payments on a straight-line basis over the lease term.

Recent Accounting Pronouncements

Recently adopted accounting guidance

Leases - In February of 2016, the FASB issued ASC 842, which replaced existing lease guidance under GAAP. Under this guidance, we recognize on our condensed balance sheet lease liabilities representing the present value of future lease payments and an associated right-of-use asset representing our right to use or control the use of specified assets for the lease term for any operating lease with a term greater than one year.

The impact of our adoption of ASC 842 did not have a material impact on our income statement or cash flow statement. The impact on our condensed balance sheets is as follows:

	September 30, 2019
(in millions)	As reported			Balance Using Previous Standard			Increase (Decrease)

Operating lease liabilities, noncurrent	52			10			42
Equity
Accumulated deficit	(200		)	(200		)	—

Recently issued accounting pronouncements

Credit Losses - In June 2016, the FASB issued ASU 2016-13 - Financial Instruments - Credit Losses (Topic 326) which requires financial assets to be presented at the net amount expected to be collected. We will be required to use forward-looking information when evaluating an allowance for our accounts receivable, unbilled revenue and other financial assets measured at amortized cost. Topic 326 also modifies the impairment guidance for available-for-sale debt securities to require an allowance for credit losses. We will adopt Topic 326 effective January 1, 2020 using a modified retrospective approach through a cumulative-effect adjustment to retained earnings. We do not expect the adoption of Topic 326 to have a material impact on our financial statements.

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 and noncurrent portions of these trust accounts as restricted cash, cash equivalents and investments on the consolidated balance sheets.

We require our clients to prefund their payroll and related taxes and other withholding liabilities before payroll is processed or due for payment. This prefund is included in restricted cash, cash equivalents and investments as payroll funds collected, which is designated to pay pending payrolls, payroll tax liabilities and other payroll withholdings.

We also invest available corporate funds, primarily in fixed income securities which meet the requirements of our corporate investment policy and are classified as available for sale (AFS).

Our total cash, cash equivalents and investments are summarized below:

FINANCIAL STATEMENTS

Gross unrealized losses as of September 30, 2019 and December 31, 2018 were not material.

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

The fair value of debt investments by contractual maturity are shown below:

(in millions)	September 30, 2019
One year or less	$	67
Over one year through five years	112
Over five years through ten years	6
Over ten years	9
Total fair value	$	194

The gross proceeds from sales and maturities of AFS securities for the three and nine months ended September 30, 2019 and September 30, 2018 are presented below. We had immaterial realized gains and losses from sales of investments for the three and nine months ended September 30, 2019 and September 30, 2018.

NOTE 4. LEASES

Our leasing activities predominantly consist of leasing office space that we occupy, which we have classified as operating leases. Our leases are comprised of fixed payments with remaining lease terms of 1 to 9 years, some of which include options to extend for up to 15 years. As of September 30, 2019, we have not included any options to extend or cancel in the calculation of our lease liability or ROU asset. We do not have any significant residual value guarantees or restrictive covenants in our leases.

During the third quarter of 2019, we recognized operating lease expense of $5 million and we recognized $14 million during the nine months ended September 30, 2019.

During the third quarter of 2019, we paid $4 million to reduce operating lease liabilities and $13 million during the nine months ended September 30, 2019. During the third quarter of 2019, we recognized $4 million in new operating lease liabilities in exchange for ROU assets and we recognized $21 million during the nine months ended September 30, 2019.

As of September 30, 2019, the weighted average remaining lease term on our operating leases was 6.2 years. Future minimum lease payments as of September 30, 2019 and December 31, 2018 were as follows:

(in millions)	September 30, 2019 (2)			December 31, 2018 (3)

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

(in millions)	September 30, 2019			December 31, 2018
Total accrued costs, end of period	$	221		$	238
Collateral paid to carriers and offset against accrued costs	(12		)	(13		)
Total accrued costs, net of carrier collateral offset	$	209		$	225
Payable in less than 1 year (net of collateral paid to carriers of $3 and $3 at September 30, 2019 and December 31, 2018, respectively)	$	63		$	67
Payable in more than 1 year (net of collateral paid to carriers of $9 and $10 at September 30, 2019 and December 31, 2018, respectively)	146			158
Total accrued costs, net of carrier collateral offset	$	209		$	225

Incurred claims related to prior years represent changes in estimates for ultimate losses on workers' compensation claims. For the three and nine months ended September 30, 2019, the change was primarily due to a decrease in estimate of ultimate losses related to older plan years and the recognition of current year development of ultimate losses.

As of September 30, 2019 and December 31, 2018, we had $56 million and $57 million, respectively, of collateral held by insurance carriers of which $12 million and $13 million, respectively, was offset against accrued workers' compensation costs as the agreements permit and are net settled against collateral held.

NOTE 6. COMMITMENTS AND CONTINGENCIES

Contingencies

We are and, from time to time, have been and may in the future become involved in various litigation matters, legal proceedings, and claims arising in the ordinary course of our business, including disputes with our clients or various class action, collective action, representative action, and other proceedings arising from the nature of our co-employment relationship with our clients and WSEs in which we are named as a defendant. In addition, due to the nature of our co-employment relationship with our clients and WSEs, we could be subject to liability for federal and state law violations, even if we do not participate in such violations. While our agreements with our clients contain indemnification provisions related to the conduct of our clients, we may not be able to avail ourselves of such provisions in every instance. We have accrued our current best estimates of probable losses with respect to these matters, which are individually and in aggregate immaterial to our consolidated financial statements.

While the outcome of the matters described above cannot be predicted with certainty, management currently does not believe that any such claims or proceedings will have a materially adverse effect on our consolidated financial position, results of operations, or cash flows. However, the unfavorable resolution of any particular matter or our reassessment of our exposure for any of the above matters based on additional information obtained in the future could have a material impact on our consolidated financial position, results of operations, or cash flows.

NOTE 7. STOCKHOLDERS’ EQUITY

Equity-Based Incentive Plans

Our 2019 Equity Incentive Plan (the 2019 Plan), approved in May 2019, replaced our 2009 Equity Incentive Plan and provides for the grants of options (both non-qualified and incentive stock options), stock appreciation rights, restricted stock, RSUs, performance awards (each as defined in the 2019 Plan) and other cash and stock based awards. Shares available for grant as of September 30, 2019 were 2,920,251.

Restricted Stock Units (RSUs) and Restricted Stock Awards (RSAs)

Time-based RSUs and RSAs generally vest over 4 years. Performance-based RSUs and RSAs are subject to vesting requirements based on certain financial performance metrics as defined in the grant notice. Actual number of shares earned may range from 0% to 200% of the target award. Awards granted in 2019 and 2018 are based on a single-year performance period subject to subsequent multi-year vesting with 50% of the shares earned vesting in 1 year after the performance period and the remaining shares in the year after.

During the nine months ended September 30, 2019, we repurchased 1,482,655 shares of common stock for approximately $84 million. As of September 30, 2019, approximately $292 million remained available for further repurchases of our common stock under all authorizations from our board of directors under this program.

NOTE 8. INCOME TAXES

Our effective income tax rate was 18% and 16% for the third quarter of 2019 and 2018, respectively, and 20% and 18% for the nine months ended September 30, 2019 and 2018, respectively. The increase in rate for the third quarter of 2019 was primarily due to a decrease in tax credits and a benefit from revaluation of deferred taxes recorded in the prior year. The increase in rate for the year to date for 2019 when compared to the same period in 2018 consists primarily of decreases in excludable income for state tax purposes and tax benefits recognized from excess tax benefits related to stock based compensation in addition to an increase in uncertain tax positions. These expenses are partially offset by a one-time benefit associated with prior year tax expense.

During the nine months ended September 30, 2019, there was an increase of $1 million in our unrecognized tax benefits. The total amount of gross interest and penalties accrued was immaterial. It is reasonably possible the amount of the unrecognized benefit could increase or decrease within the next twelve months, which would have an impact on net income.

We are subject to tax in U.S. federal and various state and local jurisdictions, as well as Canada. We are open to federal and significant state income tax examinations for tax years 2015 and subsequent years.

FINANCIAL STATEMENTS

We previously paid Notices of Proposed Assessments disallowing employment tax credits totaling $11 million, plus interest of $4 million in connection with the IRS examination of Gevity HR, Inc. and its subsidiaries, which was acquired by TriNet in June 2009. TriNet filed suit in June 2016 to recover the disallowed credits, and the issue is being resolved through the litigation process. TriNet and the U.S. filed cross motions for summary judgment in this matter in federal district court on February 27, 2018. On September 17, 2018, the district court granted our motion for summary judgment and denied the U.S.' motion. On January 18, 2019, the district court entered judgment in favor of TriNet in the amount of $15 million, plus interest. The U.S. filed a notice of appeal of the district court's decision on March 18, 2019. The U.S. filed its opening brief in the court of appeals on June 10, 2019 and we filed our answering brief on July 24, 2019 to which the government filed its reply brief on September 6, 2019. We will continue to vigorously defend our position through the litigation process.

NOTE 10. FINANCIAL INSTRUMENTS AND FAIR VALUE MEASUREMENTS

Fair Value of Financial Instruments

We use an independent pricing source to determine the fair value of our AFS. The independent pricing source utilizes various pricing models for each asset class; including the market approach. The inputs and assumptions for the pricing models are market observable inputs including trades of comparable securities, dealer quotes, credit spreads, yield curves and other market-related data.

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

The carrying value of the Company's cash equivalents and restricted cash equivalents approximate their fair values due to their short-term maturities. The Company's investments are valued using quoted market prices and multiple dealer quotes.

We did not have any Level 3 financial instruments recognized in our balance sheet as of September 30, 2019 and December 31, 2018. There were no transfers between levels as of September 30, 2019 and December 31, 2018.

Fair Value Measurements on a Recurring Basis

Fair Value of Financial Instruments Disclosure

Long-Term Debt

Our long-term debt is a floating rate debt and the fair value of our floating rate debt approximates its carrying value (exclusive of issuance costs) at September 30, 2019. The fair value of our floating rate debt is estimated based on a discounted cash flow, which incorporates credit spreads and market interest rates to estimate the fair value and is considered Level 3 in the hierarchy for fair value measurement.

Derivative Instruments

In June 2019, we entered into an interest rate collar derivative transaction with no upfront premium to mitigate the risk of changes in interest rates on the interest payments on a portion of our floating rate debt. If short-term interest rates increase, we will incur higher interest expense on any future outstanding balances of floating rate debt. We use this derivative as part of our interest rate risk management strategy and designated it as a cash flow hedge. If interest rates rise above the cap strike rate on the contract, we will receive variable-rate amounts and if interest rates fall below the floor strike rate on the contract, we will pay variable-rate amounts.

The following table summarizes the fair value of our derivative instruments at September 30, 2019:

	September 30, 2019
					Fair Market Value
(in millions)	Hedge type	Final settlement date	Notional amount		Other current assets		Accounts payable and other current liabilities

Collar - LIBOR	Cash flow	May 2022	$	213	$	—	$	—

43

FINANCIAL STATEMENTS

The pre-tax effect of derivative instruments for the three and nine months ended September 30, 2019 is insignificant and we estimate that an insignificant amount of net derivative gains or losses included in other comprehensive income will be reclassified into earnings within the following 12 months. There were no cash flows associated with the derivative for the three months and nine months ended September 30, 2019.

As of September 30, 2019, we do not hold, nor have we posted, any collateral related to the above derivative instrument.

The interest rate collar derivative is classified as Level 2 in the fair value hierarchy as its value is determined using observable inputs such as forward LIBOR curves.

Description of Business and Significant Accounting Policies - (Policies)

9 Months Ended

Sep. 30, 2019

Organization, Consolidation and Presentation of Financial Statements [Abstract]

Segment Information

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

Basis of Presentation

These unaudited condensed consolidated financial statements and accompanying notes have been prepared in accordance with accounting principles generally accepted in the United States of America for interim financial reporting and the instructions to Form 10-Q and Rule 10-01 of Regulation S-X of the Rules and Regulations of the Securities and Exchange Commission. Certain information and note disclosures included in our annual financial statements prepared in accordance with GAAP have been condensed or omitted pursuant to such rules and regulations. In the opinion of management, the condensed consolidated financial statements reflect all adjustments, that are normal and recurring in nature, necessary for fair financial statement presentation. The results of operations for the three and nine months ended September 30, 2019 are not necessarily indicative of the operating results anticipated for the full year. These Financial Statements should be read in conjunction with the audited Consolidated Financial Statements included in Part II, Item 8 Financial Statements and Supplementary Data of our Annual Report on Form 10-K for the year ended December 31, 2018 (2018 Form 10-K).

Reclassifications

Certain prior year amounts have been reclassified to conform to current period presentation.

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 (accrued workers' compensation costs) related to workers' compensation and workers' compensation collateral receivable,

• accrued health insurance costs,

• liability for insurance premiums payable,

• valuation of the investment portfolio,

• 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.

Accrued Health Insurance Costs

We sponsor and administer a number of fully insured, risk-based employee benefit plans, including group health, dental, and vision as an employer plan sponsor under section 3(5) of the ERISA. In the nine months ended September 30, 2019, the majority of our group health insurance costs related to risk-based plans. Our remaining group health insurance costs were for guaranteed-cost policies.

Accrued health insurance costs are established to provide for the estimated unpaid costs of reimbursing the carriers for paying claims within the deductible layer in accordance with risk-based health insurance policies. These accrued costs include estimates for reported losses, plus estimates for claims incurred but not paid. We assess accrued health insurance costs regularly based upon independent actuarial studies that include other relevant factors such as current and historical claims payment patterns, plan enrollment and medical trend rates.

In certain carrier contracts we are required to prepay the expected claims activity for subsequent periods. These prepaid balances by agreement permit net settlement of obligations and offset the accrued health insurance costs.

Derivative Instruments

In June 2019, we entered into an interest rate collar derivative transaction with no upfront premium to mitigate the risk of changes in interest rates on our floating rate debt. This derivative, for which we have elected and qualify for cash flow hedge accounting, is recorded on the balance sheet at its fair value. Changes in the derivative’s fair value are recorded each period in other comprehensive income until the underlying monthly interest payment and the corresponding portion of the derivative are settled, at which point changes in fair value are recorded in net income.

We adopted ASU 2016-02 - Leases (ASC 842) effective January 1, 2019 using the optional transition method, under which we recognized the cumulative effects of initially applying the standard as an adjustment to the opening balance of retained earnings on January 1, 2019 with unchanged comparative periods. As part of this adoption, we elected the following practical expedients:

• not to reassess 1) whether any contracts that existed prior to adoption have or contain leases, 2) the classification of our existing leases or 3) initial direct costs for existing leases,

• to use the practical expedient of using hindsight to determine the lease terms and evaluate any impairments in right-of-use assets upon transition, and

• not separately record non-lease and lease components for all leases in which we act as a lessee.

We determine if a new contractual arrangement is a lease at contract inception. If a contract contains a lease, we evaluate whether it should be classified as an operating or a finance lease. If applicable as a lease, we record our lease liabilities and ROU assets based on the future minimum lease payments over the lease term and only include options to renew a lease in the future minimum lease payments if it is reasonably certain that we will exercise that option. For certain leases with original terms of twelve months or less we recognize the lease expense as incurred and we do not recognize lease liabilities and ROU assets.

We measure our lease liabilities based on the future minimum lease payments discounted over the lease term. We determine our discount rate at lease inception using our incremental borrowing rate, which is based on our outstanding term debts that are collateralized by certain corporate assets. As of September 30, 2019, the weighted-average rate used in discounting the lease liability was 4%.

We measure our ROU assets based on the associated lease liabilities adjusted for any lease incentives such as tenant improvement allowances and classify operating ROU assets in other assets in our condensed consolidated balance sheet. For operating leases, we recognize expense for lease payments on a straight-line basis over the lease term.

Recent Accounting Pronouncements

Recently adopted accounting guidance

Leases - In February of 2016, the FASB issued ASC 842, which replaced existing lease guidance under GAAP. Under this guidance, we recognize on our condensed balance sheet lease liabilities representing the present value of future lease payments and an associated right-of-use asset representing our right to use or control the use of specified assets for the lease term for any operating lease with a term greater than one year.

The impact of our adoption of ASC 842 did not have a material impact on our income statement or cash flow statement. The impact on our condensed balance sheets is as follows:

	September 30, 2019
(in millions)	As reported			Balance Using Previous Standard			Increase (Decrease)

Operating lease liabilities, noncurrent	52			10			42
Equity
Accumulated deficit	(200		)	(200		)	—

Recently issued accounting pronouncements

Credit Losses - In June 2016, the FASB issued ASU 2016-13 - Financial Instruments - Credit Losses (Topic 326) which requires financial assets to be presented at the net amount expected to be collected. We will be required to use forward-looking information when evaluating an allowance for our accounts receivable, unbilled revenue and other financial assets measured at amortized cost. Topic 326 also modifies the impairment guidance for available-for-sale debt securities to require an allowance for credit losses. We will adopt Topic 326 effective January 1, 2020 using a modified retrospective approach through a cumulative-effect adjustment to retained earnings. We do not expect the adoption of Topic 326 to have a material impact on our financial statements.

Fair Value Measurement

Fair Value of Financial Instruments

We use an independent pricing source to determine the fair value of our AFS. The independent pricing source utilizes various pricing models for each asset class; including the market approach. The inputs and assumptions for the pricing models are market observable inputs including trades of comparable securities, dealer quotes, credit spreads, yield curves and other market-related data.

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

Equity-Based Incentive Plans

Our 2019 Equity Incentive Plan (the 2019 Plan), approved in May 2019, replaced our 2009 Equity Incentive Plan and provides for the grants of options (both non-qualified and incentive stock options), stock appreciation rights, restricted stock, RSUs, performance awards (each as defined in the 2019 Plan) and other cash and stock based awards. Shares available for grant as of September 30, 2019 were 2,920,251.

Restricted Stock Units (RSUs) and Restricted Stock Awards (RSAs)

Time-based RSUs and RSAs generally vest over 4 years. Performance-based RSUs and RSAs are subject to vesting requirements based on certain financial performance metrics as defined in the grant notice. Actual number of shares earned may range from 0% to 200% of the target award. Awards granted in 2019 and 2018 are based on a single-year performance period subject to subsequent multi-year vesting with 50% of the shares earned vesting in 1 year after the performance period and the remaining shares in the year after.

The following table summarizes RSU and RSA activity under our equity-based plans for the nine months ended September 30, 2019:

	RSUs				RSAs
	Number of Units		Weighted-Average Grant Date Fair Value		Number of Units		Weighted-Average Grant Date Fair Value
Nonvested at December 31, 2018	1,737,554		$	32.83	346,792		$	49.13

Nonvested at September 30, 2019	1,558,577		$	44.63	297,647		$	49.11

Stock Based Compensation

Stock based compensation expense is measured based on the fair value of the stock award on the grant date and recognized over the requisite service period for each separately vesting portion of the stock 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

In February 2019, our board of directors authorized a $300 million incremental increase to our ongoing stock repurchase program initiated in May 2014. During the nine months ended September 30, 2019, we repurchased 1,482,655 shares of common stock for approximately $84 million. As of September 30, 2019, approximately $292 million remained available for further repurchases of our common stock under all authorizations from our board of directors under this program.

CASH, CASH EQUIVALENTS AND INVESTMENTS

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 and noncurrent portions of these trust accounts as restricted cash, cash equivalents and investments on the consolidated balance sheets.

We require our clients to prefund their payroll and related taxes and other withholding liabilities before payroll is processed or due for payment. This prefund is included in restricted cash, cash equivalents and investments as payroll funds collected, which is designated to pay pending payrolls, payroll tax liabilities and other payroll withholdings.

We also invest available corporate funds, primarily in fixed income securities which meet the requirements of our corporate investment policy and are classified as available for sale (AFS).

Our total cash, cash equivalents and investments are summarized below:

All of our investment securities that have a contractual maturity date greater than three months are classified as AFS. The amortized cost, gross unrealized gains, gross unrealized losses, and fair values of our investments as of September 30, 2019 and December 31, 2018 are presented below.

Gross unrealized losses as of September 30, 2019 and December 31, 2018 were not material.

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

The fair value of debt investments by contractual maturity are shown below:

(in millions)	September 30, 2019
One year or less	$	67
Over one year through five years	112
Over five years through ten years	6

Financial Instruments and Fair Value Measurements

Investments, Debt and Equity Securities [Abstract]

FINANCIAL INSTRUMENTS AND FAIR VALUE MEASUREMENTS

FINANCIAL INSTRUMENTS AND FAIR VALUE MEASUREMENTS

Fair Value of Financial Instruments

We use an independent pricing source to determine the fair value of our AFS. The independent pricing source utilizes various pricing models for each asset class; including the market approach. The inputs and assumptions for the pricing models are market observable inputs including trades of comparable securities, dealer quotes, credit spreads, yield curves and other market-related data.

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

The carrying value of the Company's cash equivalents and restricted cash equivalents approximate their fair values due to their short-term maturities. The Company's investments are valued using quoted market prices and multiple dealer quotes.

We did not have any Level 3 financial instruments recognized in our balance sheet as of September 30, 2019 and December 31, 2018. There were no transfers between levels as of September 30, 2019 and December 31, 2018.

Fair Value of Financial Instruments Disclosure

Long-Term Debt

Our long-term debt is a floating rate debt and the fair value of our floating rate debt approximates its carrying value (exclusive of issuance costs) at September 30, 2019. The fair value of our floating rate debt is estimated based on a discounted cash flow, which incorporates credit spreads and market interest rates to estimate the fair value and is considered Level 3 in the hierarchy for fair value measurement.

Derivative Instruments

In June 2019, we entered into an interest rate collar derivative transaction with no upfront premium to mitigate the risk of changes in interest rates on the interest payments on a portion of our floating rate debt. If short-term interest rates increase, we will incur higher interest expense on any future outstanding balances of floating rate debt. We use this derivative as part of our interest rate risk management strategy and designated it as a cash flow hedge. If interest rates rise above the cap strike rate on the contract, we will receive variable-rate amounts and if interest rates fall below the floor strike rate on the contract, we will pay variable-rate amounts.

The following table summarizes the fair value of our derivative instruments at September 30, 2019:

	September 30, 2019
					Fair Market Value
(in millions)	Hedge type	Final settlement date	Notional amount		Other current assets		Accounts payable and other current liabilities
Derivatives designated as hedging instruments
Collar - LIBOR	Cash flow	May 2022	$	213	$	—	$	—

The pre-tax effect of derivative instruments for the three and nine months ended September 30, 2019 is insignificant and we estimate that an insignificant amount of net derivative gains or losses included in other comprehensive income will be reclassified into earnings within the following 12 months. There were no cash flows associated with the derivative for the three months and nine months ended September 30, 2019.

As of September 30, 2019, we do not hold, nor have we posted, any collateral related to the above derivative instrument.

The interest rate collar derivative is classified as Level 2 in the fair value hierarchy as its value is determined using observable inputs such as forward LIBOR curves.

Contingencies

We are and, from time to time, have been and may in the future become involved in various litigation matters, legal proceedings, and claims arising in the ordinary course of our business, including disputes with our clients or various class action, collective action, representative action, and other proceedings arising from the nature of our co-employment relationship with our clients and WSEs in which we are named as a defendant. In addition, due to the nature of our co-employment relationship with our clients and WSEs, we could be subject to liability for federal and state law violations, even if we do not participate in such violations. While our agreements with our clients contain indemnification provisions related to the conduct of our clients, we may not be able to avail ourselves of such provisions in every instance. We have accrued our current best estimates of probable losses with respect to these matters, which are individually and in aggregate immaterial to our consolidated financial statements.

While the outcome of the matters described above cannot be predicted with certainty, management currently does not believe that any such claims or proceedings will have a materially adverse effect on our consolidated financial position, results of operations, or cash flows. However, the unfavorable resolution of any particular matter or our reassessment of our exposure for any of the above matters based on additional information obtained in the future could have a material impact on our consolidated financial position, results of operations, or cash flows.

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 (accrued workers' compensation costs) related to workers' compensation and workers' compensation collateral receivable,

• accrued health insurance costs,

• liability for insurance premiums payable,

• valuation of the investment portfolio,

• 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.

Accrued Health Insurance Costs

We sponsor and administer a number of fully insured, risk-based employee benefit plans, including group health, dental, and vision as an employer plan sponsor under section 3(5) of the ERISA. In the nine months ended September 30, 2019, the majority of our group health insurance costs related to risk-based plans. Our remaining group health insurance costs were for guaranteed-cost policies.

Accrued health insurance costs are established to provide for the estimated unpaid costs of reimbursing the carriers for paying claims within the deductible layer in accordance with risk-based health insurance policies. These accrued costs include estimates for reported losses, plus estimates for claims incurred but not paid. We assess accrued health insurance costs regularly based upon independent actuarial studies that include other relevant factors such as current and historical claims payment patterns, plan enrollment and medical trend rates.

In certain carrier contracts we are required to prepay the expected claims activity for subsequent periods. These prepaid balances by agreement permit net settlement of obligations and offset the accrued health insurance costs. As of September 30, 2019 and December 31, 2018, prepayments included in accrued health insurance costs were $39 million and $33 million, respectively. When the prepaid is in excess of our recorded liability, the net asset position is included in prepaid expenses. As of September 30, 2019 and December 31, 2018, accrued health insurance costs included in prepaid expenses were $53 million and $50 million, respectively.

Derivative Instruments

In June 2019, we entered into an interest rate collar derivative transaction with no upfront premium to mitigate the risk of changes in interest rates on our floating rate debt. This derivative, for which we have elected and qualify for cash flow hedge accounting, is recorded on the balance sheet at its fair value. Changes in the derivative’s fair value are recorded each period in other comprehensive income until the underlying monthly interest payment and the corresponding portion of the derivative are settled, at which point changes in fair value are recorded in net income. We evaluate this derivative each quarter to determine that it remains effective by comparing the remaining expected cash flows of the derivative against the related expected interest payments of our floating rate debt. We do not enter into any derivatives for trading or other speculative purposes.

Leases

We adopted ASU 2016-02 - Leases (ASC 842) effective January 1, 2019 using the optional transition method, under which we recognized the cumulative effects of initially applying the standard as an adjustment to the opening balance of retained earnings on January 1, 2019 with unchanged comparative periods. As part of this adoption, we elected the following practical expedients:

• not to reassess 1) whether any contracts that existed prior to adoption have or contain leases, 2) the classification of our existing leases or 3) initial direct costs for existing leases,

• to use the practical expedient of using hindsight to determine the lease terms and evaluate any impairments in right-of-use assets upon transition, and

• not separately record non-lease and lease components for all leases in which we act as a lessee.

We determine if a new contractual arrangement is a lease at contract inception. If a contract contains a lease, we evaluate whether it should be classified as an operating or a finance lease. If applicable as a lease, we record our lease liabilities and ROU assets based on the future minimum lease payments over the lease term and only include options to renew a lease in the future minimum lease payments if it is reasonably certain that we will exercise that option. For certain leases with original terms of twelve months or less we recognize the lease expense as incurred and we do not recognize lease liabilities and ROU assets.

We measure our lease liabilities based on the future minimum lease payments discounted over the lease term. We determine our discount rate at lease inception using our incremental borrowing rate, which is based on our outstanding term debts that are collateralized by certain corporate assets. As of September 30, 2019, the weighted-average rate used in discounting the lease liability was 4%.

We measure our ROU assets based on the associated lease liabilities adjusted for any lease incentives such as tenant improvement allowances and classify operating ROU assets in other assets in our condensed consolidated balance sheet. For operating leases, we recognize expense for lease payments on a straight-line basis over the lease term.

Recent Accounting Pronouncements

Recently adopted accounting guidance

Leases - In February of 2016, the FASB issued ASC 842, which replaced existing lease guidance under GAAP. Under this guidance, we recognize on our condensed balance sheet lease liabilities representing the present value of future lease payments and an associated right-of-use asset representing our right to use or control the use of specified assets for the lease term for any operating lease with a term greater than one year.

The impact of our adoption of ASC 842 did not have a material impact on our income statement or cash flow statement. The impact on our condensed balance sheets is as follows:

Recently issued accounting pronouncements

Credit Losses - In June 2016, the FASB issued ASU 2016-13 - Financial Instruments - Credit Losses (Topic 326) which requires financial assets to be presented at the net amount expected to be collected. We will be required to use forward-looking information when evaluating an allowance for our accounts receivable, unbilled revenue and other financial assets measured at amortized cost. Topic 326 also modifies the impairment guidance for available-for-sale debt securities to require an allowance for credit losses. We will adopt Topic 326 effective January 1, 2020 using a modified retrospective approach through a cumulative-effect adjustment to retained earnings. We do not expect the adoption of Topic 326 to have a material impact on our financial statements.

Income Tax Disclosure [Abstract]

INCOME TAXES

INCOME TAXES

Our effective income tax rate was 18% and 16% for the third quarter of 2019 and 2018, respectively, and 20% and 18% for the nine months ended September 30, 2019 and 2018, respectively. The increase in rate for the third quarter of 2019 was primarily due to a decrease in tax credits and a benefit from revaluation of deferred taxes recorded in the prior year. The increase in rate for the year to date for 2019 when compared to the same period in 2018 consists primarily of decreases in excludable income for state tax purposes and tax benefits recognized from excess tax benefits related to stock based compensation in addition to an increase in uncertain tax positions. These expenses are partially offset by a one-time benefit associated with prior year tax expense.

During the nine months ended September 30, 2019, there was an increase of $1 million in our unrecognized tax benefits. The total amount of gross interest and penalties accrued was immaterial. It is reasonably possible the amount of the unrecognized benefit could increase or decrease within the next twelve months, which would have an impact on net income.

We are subject to tax in U.S. federal and various state and local jurisdictions, as well as Canada. We are open to federal and significant state income tax examinations for tax years 2015 and subsequent years.

We previously paid Notices of Proposed Assessments disallowing employment tax credits totaling $11 million, plus interest of $4 million in connection with the IRS examination of Gevity HR, Inc. and its subsidiaries, which was acquired by TriNet in June 2009. TriNet filed suit in June 2016 to recover the disallowed credits, and the issue is being resolved through the litigation process. TriNet and the U.S. filed cross motions for summary judgment in this matter in federal district court on February 27, 2018. On September 17, 2018, the district court granted our motion for summary judgment and denied the U.S.' motion. On January 18, 2019, the district court entered judgment in favor of TriNet in the amount of $15 million, plus interest. The U.S. filed a notice of appeal of the district court's decision on March 18, 2019. The U.S. filed its opening brief in the court of appeals on June 10, 2019 and we filed our answering brief on July 24, 2019 to which the government filed its reply brief on September 6, 2019. We will continue to vigorously defend our position through the litigation process.

LEASES

Our leasing activities predominantly consist of leasing office space that we occupy, which we have classified as operating leases. Our leases are comprised of fixed payments with remaining lease terms of 1 to 9 years, some of which include options to extend for up to 15 years. As of September 30, 2019, we have not included any options to extend or cancel in the calculation of our lease liability or ROU asset. We do not have any significant residual value guarantees or restrictive covenants in our leases.

During the third quarter of 2019, we recognized operating lease expense of $5 million and we recognized $14 million during the nine months ended September 30, 2019.

During the third quarter of 2019, we paid $4 million to reduce operating lease liabilities and $13 million during the nine months ended September 30, 2019. During the third quarter of 2019, we recognized $4 million in new operating lease liabilities in exchange for ROU assets and we recognized $21 million during the nine months ended September 30, 2019.

As of September 30, 2019, the weighted average remaining lease term on our operating leases was 6.2 years. Future minimum lease payments as of September 30, 2019 and December 31, 2018 were as follows:

Incurred claims related to prior years represent changes in estimates for ultimate losses on workers' compensation claims. For the three and nine months ended September 30, 2019, the change was primarily due to a decrease in estimate of ultimate losses related to older plan years and the recognition of current year development of ultimate losses.

As of September 30, 2019 and December 31, 2018, we had $56 million and $57 million, respectively, of collateral held by insurance carriers of which $12 million and $13 million, respectively, was offset against accrued workers' compensation costs as the agreements permit and are net settled against collateral held.
