10 % increase * Non-GAAP measure. See definitions below under the heading " Non-GAAP Financial Measures ".




We continued to achieve year-over-year revenue growth, reflecting our higher
Average WSEs, rate increases and the $111 million decrease in the Recovery
Credit recognized in 2021 compared to 2020.
During 2021, our Average WSEs increased 5% and total WSEs increased 10% compared
to 2020, primarily as a result of continued hiring by clients in our installed
base.
Increased medical services utilization in 2021, combined with increased volume
due to WSE growth, resulted in higher insurance costs compared to 2020.
The growth in total revenues, partially offset by increases in insurance costs
and operating expenses, resulted in increases in our net income and Adjusted Net
Income of 24%.

2020 compared to 2019 can be found under Part II, Item 7. Management's
Discussion and Analysis in our   Annual Report on Form 10-K   for the year ended

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

Operating Metrics
Worksite Employees (WSE)
Average WSE growth is a volume measure we use to monitor the performance of our
business. Average WSEs increased 5% when comparing 2021 to 2020, primarily due
to increased hiring by clients in our installed base across most verticals in
2021, led by our Technology vertical. Most of the hiring in our installed based
in 2021 was from clients that benefited from our Recovery Credit program that we
launched in April 2020. Our Recovery Credit program was designed to assist in
the economic recovery of SMBs and to promote client loyalty and incentivize
client retention.
Total WSEs can be used to estimate our beginning WSEs for the next period and,
as a result, can be used as an indicator of our potential future success in
growing our business and retaining clients.
Anticipated revenues for future periods can diverge from the revenue expectation
derived from Average WSEs or Total WSEs due to pricing differences across our HR
solutions and services and the degree to which clients and WSEs elect to
participate in our solutions during future periods. In addition to focusing on
growing our Average WSE and Total WSE counts, we also focus on pricing
strategies, benefit participation and service differentiation to expand our
revenue opportunities. We report the impact of client and WSE participation
differences as a change in mix.
In addition to focusing on retaining and growing our WSE base, we continue to
review acquisition opportunities that would add appropriately to our scale. We
continue to invest in efforts intended to enhance client experience and manage
attrition, through operational and process improvements.

Insurance Cost Ratio (ICR)
ICR is a performance measure calculated as the ratio of insurance costs to
insurance service revenues. We believe that ICR promotes an understanding of our
insurance cost trends and our ability to align our relative pricing to risk
performance.
We purchase workers' compensation and health benefits coverage for our
colleagues and WSEs. Under the insurance policies for this coverage, we bear
claims costs up to a defined deductible amount. Our insurance costs, which
comprise a significant portion of our overall costs, are significantly affected
by our WSEs' health and workers' compensation insurance claims experience. We
set our insurance service fees for workers' compensation and health benefits in
advance for fixed benefit periods. As a result, increases in these insurance
costs above our projections, reflected as a higher ICR, result in lower net
income. Conversely, decreases in these insurance costs below our projections,
reflected as a lower ICR, result in higher net income.

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

ICR increased due to the increase in medical services utilization in 2021,
combined with COVID-19 testing, treatment and vaccination costs, which together
resulted in higher insurance costs. This was partially offset by the increase in
insurance service revenues. While medical services utilization has increased in
2021, the ICR remains below pre-pandemic levels, as access to medical systems
was constrained in regions where increases in hospitalizations arising from the
COVID-19 Delta and Omicron variants reduced preventative and elective
procedures.

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

PSR

ISR - % represents proportion of insurance service revenues to total revenues






The growth in total revenues was primarily driven by higher Average WSEs and
growth in rate, combined with the $111 million decrease in the Recovery Credit
recognized in 2021. This was partially offset by the $25 million reduction in
revenue recognized for the 2021 Credit Program.

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,

Professional Service Revenues
Our clients are primarily billed on a fee per WSE per month per transaction. Our
vertical approach provides us the flexibility to offer our clients in different
industries with varied services at different prices, which we believe
potentially reduces the value of solely using Average WSE and Total WSE counts
as indicators of future potential revenue performance.
We also analyze changes in PSR with the following measures:
•Volume - the percentage change in period over period Average WSEs,
•Rate - the weighted average percentage change in fees for each vertical,
•Mix - the change in composition of Average WSEs across our verticals, and
•Recovery Credit - the weighted average amounts recognized for the Recovery
Credit program.

The growth in PSR was driven by higher Average WSEs, a growth in rate and a $12
million decrease in the Recovery Credit recognized. The growth in rate was
weighted to our smaller clients, and included an increase in fees for other
services, including COBRA administration. We continued to experience a favorable
change in our vertical mix of WSEs, as SMBs in our Technology, Financial
Services and Professional Services verticals returned to hiring at a faster rate
than our Main Street vertical.

During 2020, stay-at-home orders and social distancing practices due to the
COVID-19 pandemic decreased medical services utilization, particularly in the
second quarter, as enrollees deferred or cancelled elective procedures and
reduced outpatient medical, dental and vision services. Medical services
utilization increased in 2021 as enrollees returned to outpatient medical,
dental and vision care and elective procedures. The higher utilization was
partially offset by reductions in some regions for part of the year due to the
surges of the COVID-19 Delta and Omicron variants. As a result, our medical
services utilization in 2021 remained below pre-pandemic levels.
The increase in medical services utilization in 2021, combined with increased
COVID-19 testing, treatment and vaccination costs, caused the increase in rate.
This was partially offset by larger positive claims development as our accrued
health costs and accrued workers' compensation costs as of December 31, 2020
were paid in 2021. The increase in volume was primarily driven by higher Average
WSEs.

Other Income (Expense)
Other income (expense) consists primarily of interest and dividend income from
investments, interest expense under our previous credit facility and interest on
our 3.50% Senior Notes due 2029 (our 2029 Notes) issued in February 2021.
[[Image Removed: tnet-20211231_g30.jpg]][[Image Removed: tnet-20211231_g31.jpg]]
Interest income decreased primarily due to lower average market interest rates.
Interest expense, bank fees and other was consistent with the prior period.
Provision for Income Taxes
Our effective tax rate (ETR) was 23% and 24% for 2021 and 2020, respectively.
The change in ETR was primarily attributable to benefits associated with a
favorable adjustment of our previously disputed receivable from the IRS.
Liquidity and Capital Resources
Liquidity
Liquidity is a measure of our ability to access sufficient cash flows to meet
the short-term and long-term cash requirements of our business operations. Our
principal source of liquidity for operations is derived from cash provided by
operating activities. We rely on cash provided by operating activities to meet
our short-term liquidity requirements, which primarily relate to the payment of
corporate payroll and other operating costs, and capital expenditures. Our cash
flow related to WSE payroll and benefits is generally matched by advance
collection from our clients. To minimize the credit risk associated with
remitting the payroll and associated taxes and benefits costs, we require
clients to prefund the payroll and related payroll taxes and benefits costs.
We believe that we can meet our present and reasonably foreseeable operating
cash needs and future commitments through existing liquid assets and continuing
cash flows from corporate operating activities.
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:

Working capital for WSEs related activities
We designate funds to ensure that we have adequate current assets to satisfy our
current obligations associated with WSEs, the Recovery Credit liability and 2021
Credit Program liability. We expect the Recovery Credit and 2021 Credit Program
aggregate liability of $48 million as of December 31, 2021 to be settled over
the following 12 months. We manage our WSE payroll and benefits obligations
through collections of payments from our clients which generally occur two to
three days in advance of client payroll dates. We regularly review our
short-term obligations associated with our WSEs (such as payroll and related
taxes, insurance premium and claim payments) and designate funds required to
fulfill these short-term obligations, which we refer to as PFC. PFC is included
in current assets as restricted cash, cash equivalents and investments.
We manage our sponsored benefit and workers' compensation insurance obligations
by maintaining collateral funds in restricted cash, cash equivalents and
investments. These collateral amounts are generally determined at the beginning
of each plan year and we may be required by our insurance carriers to adjust our
collateral balances when facts and circumstances change. We regularly review our
collateral balances with our insurance carriers and anticipate funding further
collateral in the future based upon our capital requirements. We classify our
restricted cash, cash equivalents and investments as current and noncurrent
assets to match against the anticipated timing of payments to carriers.
The following table summarizes our workers' compensation obligations, gross of
collateral, as of December 31, 2021,

Working capital for corporate purposes

Corporate working capital as of December 31, 2021 increased $410 million from
December 31, 2020, primarily driven by a $311 million increase in corporate
unrestricted cash and cash equivalents and a $78 million increase in corporate
investments.

We use our available cash and cash equivalents to satisfy our operational and
regulatory requirements and to fund capital expenditures. We believe that we can
meet our present and reasonably foreseeable operating cash needs and future
commitments through existing liquid assets, continuing cash flows from corporate
operating activities and the potential issuance of debt or equity securities. We
believe our existing corporate cash and cash equivalents and positive working
capital will be sufficient to meet our working capital expenditure needs for at
least the next twelve months.

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

Our corporate operating cash flows in 2021 increased when compared to 2020 due
to the increase in our net income and the timing of our payments of corporate
obligations.

Investments


We invest a portion of available cash in investment-grade securities with
effective maturities less than five years that are classified on our balance
sheets as investments.
We also invest funds held as collateral to satisfy our long-term obligation
towards workers' compensation liabilities. These investments are classified on
our balance sheets as restricted cash, cash equivalents and investments. We
review the amount and the anticipated holding period of these investments
regularly in conjunction with our estimated long-term workers' compensation
liabilities and anticipated claims payment trend. At December 31, 2021, our
investments had a weighted average duration of less than two years and an
average S&P credit rating of AA.
As of December 31, 2021, we held approximately $2.3 billion in restricted and
unrestricted cash, cash equivalents and investments, of which $612 million was
unrestricted cash and cash equivalents and $303 million was unrestricted
investments. Refer to   Note 2   in Part II, Item 8. Financial Statements and
Supplemental Data, in this Form 10-K for a summary of these funds.
In December 2021, we entered into a definitive agreement to acquire Zenefits.
The total purchase price of $220 million, subject to customary closing
adjustments, will be settled by the issuance of up to $20 million of TriNet
stock to eligible selling shareholders, with the remainder paid in cash from
corporate working capital. The acquisition is subject to customary closing
conditions and regulatory approval and is expected to close in the first quarter
of 2022.
Capital Expenditures
During 2021, we continued to make investments in software and hardware and we
enhanced our existing service offerings and technology platform. We expect
capital investments in our software and hardware to continue in the future.

During the year ended December 31, 2021, we repurchased 1,161,909 shares of our
common stock for approximately $94 million through our stock repurchase program.
As of December 31, 2021, approximately $263 million remained available for
repurchase under all authorizations by our board of directors. We plan to use
current cash and cash generated from ongoing operating activities to fund this
stock repurchase program.
In February 2022, our board of directors authorized a $300 million incremental
increase to our ongoing stock repurchase program initiated in May 2014. We use
this program to return value to our stockholders and to offset dilution from the
issuance of stock under our equity-based incentive plan and employee purchase
plan.
In February 2021, we issued $500 million aggregate principal amount of our 2029
Notes. $370 million of the proceeds was used to repay and terminate the 2018
Term Loan A. The remaining funds were used for general corporate purposes. Refer
to   Note 6   in Part II, Item 8. Financial Statements and Supplementary Data,
of this Form 10-K for further information.
In February 2021, concurrently with the closing of our 2029 Notes offering, we
entered into a new $500 million revolving credit facility under a new credit
agreement (our 2021 Credit Agreement). The 2021 Credit Agreement includes a $100
million letter of credit sub-facility and a $40 million swingline sub-facility.
We also have the option to incur incremental credit facilities of up to the
greater of $450 million and 100% of EBITDA for the most recent period of four
fiscal quarters for which financial statements have been delivered. Such
incremental facilities are subject to obtaining additional commitments from
lenders. At December 31, 2021, we had $500 million available under our 2021
Credit Agreement.
Capital Resources
As of December 31, 2021, $500 million aggregate principal of our 2029 Notes was
outstanding. The Indenture governing the 2029 Notes includes restrictive
covenants limiting our ability to: (i) create liens on certain assets to secure
debt; (ii) grant subsidiary guarantees of certain debt without also providing a
guarantee of the 2029 Notes; and (iii) consolidate or merge with or into, or
sell or otherwise dispose of all or substantially all of our assets to, another
person, subject, in each case, to certain customary exceptions.
Our 2021 Credit Agreement includes a $500 million revolving credit facility. The
2021 Credit Agreement includes negative covenants that limit our ability to
incur indebtedness and liens, sell assets and make restricted payments,
including dividends and investments, subject to certain exceptions. In addition,
the 2021 Credit Agreement also contains other customary affirmative and negative
covenants and customary events of default. The 2021 Credit Agreement also
contains a financial covenant that requires the Company to maintain certain
maximum total net leverage ratios.
We were in compliance with all financial covenants under our 2021 Credit
Agreement at December 31, 2021.

Critical Accounting Judgments and Estimates
Our consolidated financial statements are prepared in accordance with GAAP,
which require us to make estimates, judgments, and assumptions that affect
reported amounts of assets, liabilities, revenues and expenses, and the related
disclosures of contingent assets and liabilities. These estimates are based on
historical experience and on various other assumptions that we believe to be
reasonable under the circumstances. Some of the assumptions are highly uncertain
at the time of estimation. To the extent actual experience differs from the
assumptions used, our consolidated financial statements could be materially
affected. For additional information about our accounting policies, refer to
  Note 1   in Part II, Item 8. Financial Statements and Supplementary Data, of
this Form 10-K.
The following items require significant estimation or judgment:
Insurance Costs
We purchase workers' compensation and health benefits coverage for our employees
and WSEs. As part of these insurance policies, we bear claims costs up to a
defined deductible amount and as a result, we establish accrued insurance costs
including both known claims filed and estimates for incurred but not reported
claims.
We use external actuaries to evaluate, review and recommend estimates of our
accrued workers' compensation and health insurance costs. The accrued costs
studies performed by these qualified external actuaries analyze historical
claims data to develop a range of our potential ultimate costs using loss
development, expected loss ratio and frequency/severity methods in accordance
with Actuarial Standards of Practice. These methods are applied to classes of
the claims data organized by policy year and risk class.
Key judgments and evaluations in arriving at loss estimates by class and the
accrued costs selection overall include:
•the selection of method used and the relative weights given to selecting the
method used for each policy year,
•the underlying assumptions of LDF used in these models,
•the effect of any changes to the insurers' claims handling and payment
processes,
•evaluation of medical and indemnity cost trends, costs from changes in the risk
exposure being evaluated and any applicable changes in legal, regulatory or
judicial environment.
We review and evaluate these judgments and the associated recommendations in
concluding the adequacy of accrued costs. Our quarterly reserving process
involves the collaboration of our qualified external actuaries and our actuarial
and finance departments to approve a single point best estimate. In selecting
this best estimate, management considers the actuarial estimates and applies
informed judgment regarding qualitative factors that may not be fully captured
in these actuarial estimates. Such factors include, but are not limited to: the
timing of the emergence of claims, volume and complexity of claims, social and
judicial trends, and the extent of our historical loss data versus industry
information. Where adjustments are necessary these are recorded in the period in
which the adjustments are identified.
These accrued costs may vary in subsequent quarters from the amount estimated.
Certain assumptions used in estimating these accrued costs are highly
judgmental. Our accrued costs, results of operations and financial condition can
be materially impacted if actual experience differs from the assumptions used in
establishing these accrued costs.
Accrued Workers' Compensation Costs
Under our policies, we are responsible for reimbursing the insurance carriers
for workers' compensation losses up to $1 million per claim occurrence
(Deductible Layer). As workers' compensation costs for a particular period are
not known for many years after the losses have occurred, these costs represent
our best estimate of unpaid claim losses and loss adjustment expenses within the
deductible layer in accordance with our insurance policies. We use external
actuaries to evaluate, review and recommend accrued workers' compensation costs
on a quarterly basis. The data is segmented by class and state and analyzed by
policy year, and states where we have small exposure are aggregated into a
single grouping.
                            TRINET    52     2021 FORM 10-K



--------------------------------------------------------------------------------
           MANAGEMENT'S DISCUSSION AND ANALYSIS       Table of Contents



We use a combination of loss development, expected loss ratio and
frequency/severity methods which include the following inputs, assumptions and
analytical techniques:
•Historical volume and severity of workers' compensation cost experience,
exposure data and industry loss experience related to TriNet's insurance
policies,
•inputs of WSEs' job responsibilities and location,
•estimates of future cost trends,
•expected loss ratios for the latest accident year or prior accident years,
adjusted for the loss trend, the effect of rate changes and other quantifiable
factors, and
•LDFs to project the reported losses for each accident year to an ultimate
basis.
Final cost settlements may vary materially from the present estimates,
particularly when payments do not occur until well into the future. In our
experience, plan years related to workers' compensation programs may take 10
years or more to be fully settled.
We believe that our estimate of accrued workers' compensation costs is most
sensitive to LDFs given the long reporting and paid development patterns for our
workers' compensation loss costs. Our methods of estimating accrued workers'
compensation costs rely on these LDFs and an estimate of future cost trend.
The following table illustrates the sensitivity of changes in the LDFs on our
year end estimate of insurance costs (in millions of dollars):
           Change in loss development factor    Change in insurance costs
                         -5.0%                            ($33)
                         -2.5%                            ($19)
                         +2.5%                             $20
                         +5.0%                             $40


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

                        +3.0%                            $21
                        +2.0%                            $14
                        +1.0%                            $7
                        -1.0%                           $(7)
                        -2.0%                           $(14)
                        -3.0%                           $(21)


Completion factors are an actuarial estimate based on historical experience and
analysis of current trends, of paid costs to carriers as a percentage of the
expected ultimate costs to carriers. Many factors may cause actual claims
submissions rates from our carriers to vary from our estimated completion
factors, including carrier claims processing patterns, the mix of providers and
the mix of electronic versus manual claims submitted to our carriers.
The following table illustrates the sensitivity of changes in completion factors
on our year end estimate of insurance costs (in millions of dollars):
             Change in completion factors     Change in insurance costs
                        -0.75%                           $16
                        -0.50%                           $11
                        -0.25%                           $5
                        +0.25%                          $(5)
                        +0.50%                          $(11)
                        +0.75%                          $(16)
