Item 1. Business 

General

PART I 

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

Our solutions include payroll processing, tax administration, employee benefits and an HR technology platform with 
online and mobile tools that allow our clients and worksite employees (WSEs) to store, view and manage their core 
HR-related information and efficiently conduct a variety of HR-related transactions anytime and anywhere. 

Leveraging our scale for the benefit of our clients is a key component of our business model. For example, we utilize 
our size and scale to provide our clients and WSEs access to a broad range of cost-effective employee benefit and 
insurance  programs  generally  not  available  to  individual  SMBs.  In  addition,  our  service  teams  help  with  talent 
management,  recruiting  and  training,  performance  management,  employee  onboarding  and  terminations,  benefits 
enrollment and support, claims administration and employment practices risk management. We also monitor employer-
related developments and assist clients in complying with applicable local, state and federal regulations.

Our strategy is to provide industry-specific products and services to help clients address their HR needs and allow 
them to focus on operating and growing their businesses. We believe our industry-oriented (vertical) approach is a key 
differentiator for us and delivers significant benefits to our clients. This allows our sales force, product development 
and service teams to tailor product and service offerings to the specific industry needs of our clients. As of December 
31, 2017, we have introduced five verticals TriNet Financial Services, TriNet Life Sciences, TriNet Nonprofit, TriNet 
Technology, and TriNet Main Street and we intend to continue to develop and offer new industry vertical products in 
the future.

TriNet was founded in 1988 and has significantly grown the number of clients we serve, both organically and through 
strategic acquisitions. For the year ended December 31, 2017, we processed $37.1 billion in payroll payments for 
approximately 14,800 clients with about 325,000 WSEs in all 50 states, the District of Columbia and Canada. 

Products and Services

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.

Our comprehensive HR products and solutions include the following common capabilities:

TECHNOLOGY
PLATFORM

HR EXPERTISE

BENEFITS

COMPLIANCE

  Technology Platform

Our technology platform includes online and mobile tools that allow our clients and WSEs to store, view, and manage 
core  HR  information  and  administer  a  variety  of  HR  transactions,  such  as  payroll  processing,  tax  administration, 
employee onboarding and termination, compensation reporting, expense management, and benefits enrollment and 
administration. In 2017, we made significant investments in our technology platform to provide our users with improved 
functionality, including online and mobile productivity tools, and to allow our platform to integrate more effectively with 
third-party software applications.

4

BUSINESS

Our strategy is to continue to invest in product development and improve the functionality, experience and ease of use 
of our products and services for our clients and WSEs. We will continue to design additional functionality into our core 
platform, retire legacy software systems inherited from acquisitions, and migrate clients on those legacy systems to 
our TriNet platform. We believe the continued improvement of our technology platform and the consolidation of legacy 
systems allows us to drive operating efficiencies and improve client user experience by providing a single, streamlined 
experience for accessing HR information and conducting HR transactions.

We  invested  approximately  $74  million,  $53  million  and  $39  million,  during  2017,  2016  and  2015,  respectively, 
developing our technology solutions. 

  HR Expertise

We  use  the  collective  insights  and  experience  of  our  teams  of  HR,  benefits,  risk  management  and  compliance 
professionals to help clients mitigate many of the administrative, regulatory and practical risks associated with their 
responsibilities as employers. We assist our clients in running their business by providing a variety of HR services, 
from widely used services like employee onboarding and terminations, benefits enrollment and support, employment 
practices  risk  management  and  administration,  talent  management,  recruiting  and  training,  and  performance 
management to more specialized services like immigration services. Each of our clients and WSEs have access to 
varying levels of service and support from our HR experts ranging from call center support for basic questions to pooled 
specialized  resources  and  to  onsite  consulting  and  services,  depending  on  the  needs  of  the  client  and  WSEs.  In 
addition, our teams of in-house HR professionals can also provide additional, incremental consulting and other services 
upon request.

Under our vertical strategy, we seek to design our product and service offerings for specific industries by identifying 
common  needs  and  leveraging  scale  and  shared  experience  to  provide  more  efficient  and  relevant  offerings.  For 
example, our fifth vertical product, TriNet Main Street, supports hospitality, retail, property management, and other 
similar industries. These industries are labor intensive and often operate from many disparate taxing and geographic 
locations. Based on the common needs of these industries, we have created time and attendance expertise, hiring 
and termination expertise, workers’ compensation safety consultants, and a compelling suite of benefit plans that are 
attractive to both our clients' executives and hourly workers.

  Benefits 

We offer our WSEs access to a broad range of TriNet-sponsored benefit and insurance programs at a value that we 
believe most of our clients would be unable to obtain on their own. We utilize our scale to decrease costs associated 
with our programs and look for ways to leverage our scale to provide additional benefits to our WSEs. Our benefit and 
insurance programs are compliant with state, local, and federal regulations, and our benefit and insurance service 
offerings include plan design and administration, enrollment management, and WSE and client communications. 

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

Employee Benefit Plans: We sponsor and administer several fully insured, risk-based employee benefit plans, including 
group health, dental, vision, short- and long-term disability, and life insurance as an employer plan sponsor under 
Section 3(5) of the Employee Retirement Income Security Act (ERISA). We also offer other benefit programs to our 
WSEs,  including  flexible  spending  accounts,  retirement  plans,  Consolidated  Omnibus  Budget  Reconciliation Act 
(COBRA) benefits, individual life insurance, a legal services plan, commuter benefits, home insurance, critical illness 
insurance, pet insurance and auto insurance. For further discussion of our fully insured programs including policies 
where we reimburse our carriers for certain amounts relating to claims, refer to Note 1 in Part II, Item 8 of this Form 
10-K.

5

BUSINESS

Workers' Compensation: We provide fully insured workers' compensation insurance coverage for our clients and WSEs 
through insurance policies that we negotiate with our third-party insurance carriers. Additionally, we help clients manage 
their risk by providing risk management services, including performing workplace assessment, safety consultation, 
accident investigation and other risk management services at our client locations to help prevent workplace accidents 
that could lead to claims. We also provide services to help remediate such claims when they occur.

We manage the deductible risk that we assume in connection with these policies by being selective in the types of 
businesses that we take on as new clients, by monitoring claims data and the performance of our carriers and third-
party claims management services and vendors and by providing risk management services for existing clients. 

Employment Practices Liability Insurance (EPLI): We provide EPLI coverage for our clients through insurance policies 
that we obtain from our third-party EPLI insurance carrier. These policies provide coverage for certain claims that arise 
in the course of the employment relationship such as discrimination, harassment, and certain other employee claims, 
with a per-claim retention amount. The retention amount is split between the client and TriNet, with the client generally 
paying its portion of the retention amount first.

While we do not provide legal representation to our clients, our clients can benefit from the extensive experience of 
our employment law specialists and HR professionals who assist clients in implementing HR best practices to avoid 
employment practices liability claims and in managing, processing and responding to such claims. For claims covered 
by our EPLI insurance, actual litigation defense is conducted by outside employment law firms with whom we and our 
EPLI carriers have previously negotiated rates, established billing guidelines and invoice review processes. We have 
also developed a case management protocol to efficiently and effectively defend such claims.

   Compliance

Our products and services are designed to help our clients comply with local, state and federal employment and benefit 
laws. We monitor employment-related developments and assist clients in complying with changing regulations and 
requirements at all levels, from changes in state and local employment laws, such as minimum wage and family leave 
ordinances, to sweeping federal reforms such as the 2017 Tax Cuts and Jobs Act (TCJA) and the Patient Protection 
and Affordable Care Act (ACA). Often these changes are staggered and require additional guidance from a variety of 
local, state or federal agencies, or result in complementary or responsive changes, making compliance a continuous 
challenge. Each component of our HR solutions is designed with compliance in mind, whether it is payroll processing 
and tax administration, HR services focused on creating a compliant workplace, or offering ACA-compliant benefit 
plans.

Our Co-Employment Model

We operate under a co-employment business model, under which employment-related responsibilities are contractually 
allocated between us and our clients. This model allows WSEs to receive the full benefit of our services, including our 
employee benefit plan offerings. Each of our clients enters into a client service agreement with us that defines the suite 
of professional and insurance services and benefits to be provided by us, the fees payable to us, and the division of 
responsibilities between us and our clients as co-employers. The division of responsibilities under our client service 
agreements is typically as follows:

TriNet Responsibilities 

We assume responsibility for, and manage certain risks associated with:

• 

• 

• 

• 

remittance to WSEs of salaries, wages and certain other compensation, as reported and paid to us by the client, 
related tax reporting and remittance to tax authorities and processing of garnishment and wage deduction orders. 
Unlike a payroll service provider, we issue each WSE a payroll check drawn on our bank accounts,

report the wages, withhold and deposit the associated payroll taxes as the employer for regulatory reporting and 
payroll tax returns,

provision and maintenance of workers' compensation insurance and workers' compensation claims processing,

provision and administration of group health, welfare, and retirement benefits to WSEs under TriNet-sponsored 
insurance plans,

• 

compliance with applicable law for employee benefits offered to WSEs,

6

BUSINESS

• 

• 

processing of unemployment claims, and

provision of certain HR policies, including an employee handbook describing the co-employment relationship.

Client Responsibilities 

Our clients are responsible for employment-related responsibilities that we do not assume, including: 

• 

• 

• 

• 

• 

• 

• 

• 

day-to-day management of their worksites and WSEs,

compliance with laws associated with the classification of employees as exempt or non-exempt, such as overtime 
pay and minimum wage law compliance,

accurate and timely reporting to TriNet of compensation and deduction information, including information relating 
to hours worked, rates of pay, salaries, wages and certain other compensation,

accurate and timely reporting to TriNet of information relating to workplace injuries, employee hires and termination, 
and certain other information relevant to TriNet’s services,

provision and administration of any employee benefits not provided by TriNet (e.g., equity incentive plans),

compliance with all laws and regulations applicable to the clients' workplace and business, including work eligibility 
laws, laws relating to workplace safety or the environment, laws relating to family and medical leave, laws pertaining 
to employee organizing efforts and collective bargaining and employee termination notice requirements,

payment of TriNet invoices which include wages to WSEs and applicable employment taxes and service fees, and

all other matters for which TriNet does not assume responsibility under the client service agreement, such as 
intellectual property ownership and protection and liability for products produced and/or services provided. 

As a result of our co-employment relationship with each of our WSEs, we are liable for payment of salary, wages and 
certain other compensation to the WSEs as reported and paid to us by the client and are responsible for providing 
specified employee benefits to such persons to the extent provided in each client service agreement and under federal 
and state law. In most instances, clients are required to remit payment prior to the applicable payroll date by wire 
transfer or automated clearinghouse transaction (ACH).

We also assume responsibility for payment and liability for the withholding and remittance of federal and state income 
and employment taxes with respect to salaries, wages and certain other compensation paid to WSEs, although we 
reserve the right to seek recourse against our clients for any liabilities arising out of their conduct. We perform these 
functions as the statutory employer for federal employment tax purposes, since our clients transfer legal control over 
these payroll functions to us. The laws that govern the payment of salaries, wages and related payroll taxes for our 
WSEs are very complex and the various federal, state and local laws that govern such payments can have significant 
differences. For example, except to the extent applicable federal and state laws otherwise provide, the client may be 
held ultimately liable for those obligations if we fail to remit taxes and the bonding security provided by the Employer 
Services Assurance Corporation (ESAC) or other surety is not sufficient to satisfy the obligation. 

Sales and Marketing 

We sell our solutions primarily through our direct sales organization. We have aligned our sales organization by industry 
vertical with the goal of growing profitable market share in our targeted industries. This vertical approach deepens our 
network of relationships and gives us an understanding of the unique HR needs facing SMBs in those industries. 

Our Vertical Approach

We believe that our vertical approach allows our sales force, product development and service teams to tailor product 
and service offerings to the specific industry needs of our clients. In addition to sales and marketing, our client services 
and product development teams are focused on specific industry verticals. We believe this vertical approach is an 
important competitive differentiator for TriNet and believe that it will deliver significant benefits to our clients.

7

BUSINESS

Our Sales Organization

Our sales representatives are supported by marketing, inside sales, lead generation efforts, and referral networks. 

We sponsor and participate in associations and events around the country and utilize these forums to target specific 
vertical and geographic markets. We also generate sales opportunities within key industry verticals, through marketing 
alliances and other indirect channels, such accounting firms, venture capital firms, incubators, insurance brokers, and 
other  vertical  market  industry  associations.  Additionally,  we  utilize  digital  marketing  programs,  including  digital 
advertising, search and email marketing, to create awareness and interest in our products. 

We have expanded our focus on various channel relationships and alliances that drive referrals to our direct sales 
force. Finally, our sales representatives benefit from building strong relationships with prospects during the sales and 
client service processes, resulting in referrals to new prospects as well as direct support through providing reference 
calls in regard to our products and services.

Legal and Regulatory 

Our business operates in a complex environment created by the numerous federal, state and local laws and regulations 
relating to labor and employment matters, benefit plans and income and employment taxes. The following summarizes 
what we believe are the most important legal and regulatory aspects of our business: 

Federal Regulations

Employer Status 

We sponsor our employee benefit plan offerings as the “employer” of our WSEs under the Internal Revenue Code of 
1986 (the Code), and ERISA. The multiple definitions of “employer” under both the Code and ERISA are not clear and 
most are defined in part by complex multi-factor tests under common law. We believe that we qualify as an “employer” 
of our WSEs in the U.S. under both the Code and ERISA, as well as various state regulations, but this status could 
be subject to challenge by various regulators. For additional information on employer status and its impact on our 
business and results of operations, refer to Item 1A of this Form 10-K, under the heading - If we are not recognized 
as an employer of worksite employees under federal and state regulations, or are deemed to be an insurance agent 
or third-party administrator, we and our clients could be adversely impacted.

Affordable Care Act and Health Care Reform

The Patient Protection and Affordable Care Act (ACA) was signed into law in March 2010. The ACA implemented 
sweeping health care reforms with staggered effective dates from 2010 through 2020, and many provisions in the Act 
require the issuance of additional guidance from the U.S. Department of Labor (DOL), the Internal Revenue Service 
(IRS), the U.S. Department of Health and Human Services and the states. Passage of the 2017 TCJA in December 
2017, eliminates the individual mandate tax penalty under the ACA beginning in 2019, while retaining employer ACA 
obligations. Further significant changes to health care statutes, regulations and policy at the federal, state and local 
levels could occur in 2018 and beyond, including the potential further modification, amendment or repeal of the ACA. 
For additional information on the ACA and its impact on our business and results of operations, refer to Item 1A of this 
Form 10-K, under the heading - Our business is subject to numerous complex state and federal laws, and changes 
in, uncertainty regarding, or adverse application of these laws could adversely affect our business.

Health Insurance Portability and Accountability Act

Maintaining the security of our WSEs information is important to TriNet as we sponsor employee benefit plans and 
may have access to personal health information of our WSEs. The manner in which we manage protected health 
information (PHI) is subject to the Health Insurance Portability and Accountability Act of 1996 (HIPAA), and the Health 
Information  Technology  for  Economic  and  Clinical  Health Act  of  2009  (HITECH Act).  HIPAA  contains  substantial 
restrictions and health data privacy, security and breach notification requirements with respect to the use and disclosure 
of PHI. Further, under the HITECH Act there are steep penalties and fines for HIPAA violations. Our health plans are 
covered entities under HIPAA, and we are therefore required to comply with HIPAA's portability, privacy, and security 
requirements. 

8

BUSINESS

To the extent possible, the health information we possess is anonymized and accessed through a secured third-party 
database. For additional information on the security of our clients' and WSEs' personal data and PHI and the potential 
impact to our business if we fail to protect our WSEs' PHI, refer to Item 1A of this Form 10-K, under the heading - 
Cyber-attacks or security breaches could result in reduced revenue, increased costs, liability claims or damage to our 
reputation.

Certified Professional Employer Organization (CPEO) Certification 

With  passage  of  the  Small  Business  Efficiency Act  in  2014,  the  U.S.  Congress  created  a  federal  framework  for 
professional employer organizations (PEOs) who voluntarily become certified under this law. The IRS is accepting 
applications for PEOs to become certified under the Code. Even though final regulations for the certification program 
have not yet been issued, we have applied for certification.

State Regulations

Forty-two states have adopted provisions for licensing, registration, certification or recognition of co-employers, and 
others are  considering  such  regulation. Such  laws  vary  from  state  to  state  but  generally  provide  for  monitoring  or 
ensuring the fiscal responsibility of PEOs, and in some cases codify and clarify the co-employment relationship for 
unemployment, workers' compensation and other purposes under state laws. We believe we are in compliance in all 
material respects with the requirements in those 42 states.

We must also comply with state unemployment tax requirements where our clients are located. State unemployment 
taxes are based on taxable wages and tax rates assigned by each state. The tax rates vary by state and are determined, 
in part, based on our prior years’ compensation and unemployment claims experience in each state. Certain rates are 
also determined, in part, by each client’s own compensation and unemployment claims experience. In addition, states 
have the ability under law to increase unemployment tax rates, including retroactively, to cover deficiencies in the 
unemployment tax funds. 

We must also comply with general state tax laws, including payroll tax laws. As noted above, tax reform may lead to 
significant state tax law changes in 2018 and beyond.

Strategic Acquisitions

Historically, we have pursued strategic acquisitions to both expand our product capabilities and supplement our growth 
across geographies and certain industry verticals. Our acquisition targets have included PEOs and other HR solution 
providers as well as technology companies or technology product offerings to supplement or enhance our existing HR 
solutions. We intend to continue to pursue strategic acquisitions that will enable us to add new clients and WSEs, 
expand  our  presence  in  certain  geographies  or  industry  verticals  and  offer  our  clients  and  WSEs  more  attractive 
products and services.

Client Industries and Geographies

Our clients are distributed across a variety of industries including technology, life sciences, not-for-profit, professional 
services, financial services, property management, retail, manufacturing, and hospitality. Our clients execute annual 
service contracts with us that automatically renew. Generally, our clients may cancel these contracts with thirty days' 
notice and we may cancel these contracts with thirty days' notice. 

We conduct our business primarily in the United States of America (U.S.), with more than 99% of our total revenues 
being attributable to WSEs in the U.S. and the remainder being attributable to WSEs in Canada. Substantially all our 
long-lived assets are located in the U.S.

Seasonality 

Our business is affected by seasonality in client business activity and WSE product selection during benefits open 
enrollment. Clients generally change their payroll service providers at the beginning of the payroll tax year and as a 
result, we have historically experienced our highest volumes of new and exiting clients in the month of January. Other 
periods of significant client turn-over coincide with the timing of benefit program renewals.

9

BUSINESS

Competition 

We face significant competition in the form of companies serving their HR needs in both traditional and non-traditional 
manners. These forms of competition include:

•  Other PEOs that compete directly with us,

•  HR and information systems departments and personnel of companies that perform their own administration of 

employee benefits, payroll and HR,

• 

• 

providers of certain endpoint HR services, including payroll, employee benefits and business process outsourcers 
with high-volume transaction and administrative capabilities, such as Automatic Data Processing, Inc., Paychex, 
Inc. and other third-party administrators,

employee  benefit  exchanges  that  provide  benefits  administration  services  over  the  Internet  to  companies  that 
otherwise maintain their own employee benefit plans,

• 

insurance brokers who allow third party HR systems to integrate with their platform, and

Our competitors include large PEOs such as the TotalSource unit of Automatic Data Processing, Inc., the PEO operations 
of Paychex, Inc. and Insperity, Inc., as well as specialized and smaller PEOs and similar HR service providers with 
PEO operations. If, and to the extent that, we and other companies providing these services are successful in growing 
our businesses, we anticipate that future competitors will enter this industry. 

We believe that our services are attractive to many SMBs in part because of our ability to provide access to a broad 
range of TriNet-sponsored workers' compensation, health insurance and other benefits programs on a cost-effective 
basis. We compete with insurance brokers and other providers of this coverage in this regard, and our offerings must 
be priced competitively with those provided by these competitors in order for us to attract and retain our clients.

We  believe  the  principal  competitive  factors  in  our  market  include  client  satisfaction,  ease  of  client  setup  and  on-
boarding, breadth and depth of benefit plans, vertical market expertise, total cost of service, brand awareness and 
reputation, ability to innovate and respond to client needs rapidly, online and mobile solutions, and subject matter 
expertise. We believe that we compete favorably on the basis of each of these factors.

Intellectual Property 

We own or license from third parties various computer software, as well as other intellectual property rights, used in 
our business. Generally, we protect our intellectual property rights through the use of confidentiality and non-disclosure 
agreements and policies with our employees and third-party partners and vendors, although we currently have one 
pending U.S. patent application covering our technology. We also own registered trademarks in the U.S., Canada and 
the European Union covering our name and other trademarks and logos that we believe are materially important to 
our operations.

Corporate Employees 

We refer to our employees that are not co-employed with our clients as our corporate employees. We had approximately 
2,700 corporate employees as of December 31, 2017. None of our corporate employees are covered by a collective 
bargaining agreement.

RISK FACTORS

Item 1A. Risk Factors

Our business is subject to numerous complex laws, and changes in, uncertainty regarding, or adverse application of 
these laws could negatively affect our business.

The products and services we provide to our clients are subject to numerous complex federal, state and local laws 
and regulations, including those described under the heading "Legal and Regulatory" in Item 1 of this Form10-K. Many 
of these laws (such as ERISA, the ACA and state healthcare laws, and other federal and state employment tax laws, 
such as wage and hour laws, anti-discrimination laws, etc.) may not result in a consistent approach at the federal, state 
and local level, may not specifically address PEOs and co-employment relationships or may allow significant regulatory 
interpretation  and  discretion  in  enforcement. As  a  result,  there  is  uncertainty  in  how  they  might  be  applied  to  our 
operations and those of our clients and WSEs. 

New laws, changes in existing laws, or adverse application or interpretation  of new or existing laws regarding our co-
employment relationship with our clients and WSEs (in courts, agencies or otherwise) could reduce or eliminate the 
need for, or benefit provided by, some or all of the services we provide or require us to make significant changes in 
our methods of doing business and providing services. Regulatory changes could also affect the extent and type of 
employee benefits employers can or must provide employees, the amount and type of taxes employers and employees 
are required to pay or the time within which employers must remit taxes to applicable tax authorities. Any such new 
laws, changes in laws or adverse application or interpretation of laws could have a material adverse effect on our 
financial condition and results of operations. Changes in, or uncertainty regarding, the TCJA, ACA and other health 
care reforms or tax reforms could materially impact our business and we are not able to predict the direction or ultimate 
impact of such reforms on our business operations. 

For example, the newly passed TCJA will result in sweeping changes to the taxation of individuals and businesses in 
2018 and beyond. Federal implementation of these tax reforms, and the changes to state tax laws that may result from 
federal tax reforms, may materially change the way in which we provide payroll tax services for our clients, as well as 
the business incentives that matter to our clients. Our ability to timely comply with the numerous changes under the 
TCJA and to continue to provide services that take advantage of new business incentives created by the TCJA could 
have a materially adverse effect on our ability to attract and retain clients.

Similarly, changes to and continued uncertainty regarding the implementation and future of health care reform in the 
United States under the ACA, any successor to the ACA, or related or similar state laws, has the potential to substantially 
change the health insurance market for SMBs and how such employers provide health insurance to their employees, 
which could have a materially adverse effect on our ability to attract and retain our clients. For example, the TCJA's 
elimination of the ACA individual mandate tax penalty beginning in 2019 may reduce the number of WSEs who participate 
in our insurance programs, and proposed rule changes by the DOL may increase the availability of "association health 
plans," which may compete with the health plans we provide, or impact the operation of other types of health plans, 
including the plans that we sponsor. There may also be significant additional changes to the ACA in 2018 and beyond, 
including the potential modification, amendment or repeal of the ACA. Tax reform changes brought about by the TCJA 
and changes to federal health care laws, including to the ACA, could also result in new or amended laws being introduced 
at the state or local level. In addition, state tax regulators may engage in their own tax reforms as a result of the passage 
of the TCJA. Our ability to comply with, and adapt our product offerings to take advantage of, any such changes could 
require significant additional costs and divert management attention, which could result in a material adverse effect 
on our financial condition and results of operations.

If we are not recognized as an employer of worksite employees under federal and state regulations, or are deemed to 
be an insurance agent or third-party administrator, we and our clients could be adversely impacted.

In order to sponsor our employee benefit plan offerings for WSEs, we must qualify as an employer of WSEs for certain 
purposes under the Code and ERISA. In addition, our status as an employer is important for purposes of ERISA’s 
preemption of certain state laws. The definition of employer under various laws is not uniform, and under both the 
Code and ERISA, the term is defined in part by complex multi-factor tests. 

Generally, these tests are designed to evaluate whether an individual is an independent contractor or employee and 
they provide substantial weight to whether a purported employer has the right to direct and control the details of an 
individual's work. Some factors that the IRS has considered important in the past in evaluating this issue have included 
the employer’s degree of behavioral control (the extent of instructions, training and the nature of the work), financial 
control and the economic aspects of the work relationship, the intent of the parties, as evidenced by the specific benefit, 

12

RISK FACTORS

contract, termination and other similar arrangements between the parties and the on-going versus project-oriented 
nature of the work to be performed. However, a definitive judicial interpretation of “employer” in the context of PEOs 
has not been established. For ERISA purposes, for example, courts have held that test factors relating to ability to 
control and supervise an individual are less important, while the U.S. Department of Labor has issued guidance that 
certain entities in the HR outsourcing industry do not qualify as common law employers for ERISA purposes. Although 
we believe that we qualify as an employer of WSEs under ERISA and the U.S. Department of Labor has not provided 
guidance otherwise, we are not able to predict the outcome of any future regulatory challenge. 

If we were found not to be an employer for ERISA purposes, it could adversely affect the manner in which we are able 
to provide employee benefits to WSEs. Similarly, to qualify for favorable tax treatment under the Code, certain employee 
benefit plans, such as 401(k) retirement plans and cafeteria plans must be established and maintained by an employer 
for the exclusive benefit of its employees. All of our 401(k) retirement plans are operated pursuant to guidance provided 
by the IRS and we have received favorable determination letters from the IRS confirming the qualified status of the 
plans. However, the IRS uses its own complex, multi-factor test to ascertain whether an employment relationship exists 
between a worker and a purported employer. Although we believe that we qualify as an employer of WSEs under the 
Code, we cannot assure you that the IRS will not challenge this position or continue to provide favorable determination 
letters. Moreover, the IRS' 401(k) guidance and qualification requirements are not applicable to the operation of our 
cafeteria plans. 

If we are not recognized as an employer under the Code or ERISA, we may be required to change the method by 
which we report and remit payroll taxes to the tax authorities and the method by which we provide, or discontinue 
providing, certain employee benefits to WSEs, which could have a material adverse effect on our business and results 
of operations.

We  must  also  qualify  as  co-employers  of  WSEs  and  comply  with  state  licensing,  certification  and  registration 
requirements for the regulation of PEOs. Forty-two states have passed such laws and other states may implement 
such requirements in the future. While we believe that we satisfy these state regulations, these requirements vary from 
state to state and change frequently and if we are not able to satisfy existing or future licensing requirements or other 
applicable regulations in any state, we may be prohibited from doing business in that state. 

In addition, state regulatory authorities generally impose licensing requirements on companies acting as insurance 
agents or third-party administrators, such as those that handle health or retirement plan funding and claim processing. 
We do not believe that our current activities require such licensing, but if regulatory authorities in any state determine 
that we are acting as an insurance agent or as a third-party administrator, we may need to hire additional personnel 
to manage regulatory compliance and become obligated to pay annual regulatory fees, which could have a material 
adverse effect on our financial condition and results of operations.

Our co-employment relationship with our worksite employees exposes us to business risks.

We  are  the  co-employer  of  our  WSEs.  As  the  co-employer  of  our  WSEs,  we  assume  certain  obligations  and 
responsibilities of an employer. For instance, we are responsible for providing health benefits to our WSEs regardless 
of  whether  the  cost  of  providing  benefits  exceeds  the  fees  received  from  our  clients.  However,  the  extent  of  our 
responsibility for other aspects of our co-employer relationship with our WSEs remains subject to regulatory uncertainty 
at the state and federal level. For example, under certain circumstances, we may be found to be responsible for paying 
salaries, wages and related payroll taxes of our WSEs, even if our clients have not timely remitted payments to us.

We co-employ people in our clients' workplaces. Our ability to control the workplace environment of our clients is 
limited. As a co-employer of WSEs, there is a possibility that we may be subject to liability for violations of employment 
or other laws and other acts and omissions by our clients or WSEs even if we do not participate in any such acts or 
omissions. State and federal regulations interpreting co-employment relationships are in a constant state of flux and 
we cannot predict when changes will occur or forecast whether any particular future changes will be favorable to our 
operations or not.

We seek to mitigate these risks through our client agreements and insurance coverage. Our agreements with our 
clients establish the contractual division of responsibilities between us and our clients and that they will indemnify us 
for any liability attributable to their own or our WSEs' conduct, however, we may not be able to effectively enforce or 
collect on these contractual obligations. In addition, we maintain insurance coverage, including workers’ compensation, 
directors and officers and employment practices liability insurance coverage, to limit our and our clients' exposure to 
various  WSE  related  claims,  but  we  are  still  responsible  for  any  deductible  layer  under  such  insurance  and  such 
insurance generally excludes coverage for claims relating to the classification of employees as exempt or non-exempt, 

13

RISK FACTORS

other wage and hour issues, and employment contract disputes, among other things. We cannot assure you that our 
insurance will be sufficient in amount or scope to cover all claims that may be asserted against us and for which we 
are unable to obtain indemnification from our clients. 

Negative publicity relating to events or activities attributed to us, our corporate employees, WSEs, or others associated 
with any of these parties, whether or not justified, may tarnish our reputation and reduce the value of our brand. In 
addition, if our brand is negatively impacted, it may have a material adverse effect on our business, including creating 
challenges in retaining clients or attracting new clients and hiring and retaining employees. 

Cyber-attacks or security breaches could result in reduced revenue, increased costs, liability claims or damage to our 
reputation.

Maintaining the security of our IT infrastructure and the confidentiality of our clients' and WSEs' personal data and 
information is paramount for us and our clients. Clients using our technology platform rely on the security of our IT 
infrastructure to ensure the reliability of our products and services and the protection of sensitive client and WSE data. 
We use and store a large amount of personal and confidential information about our clients, WSEs and colleagues, 
including bank account and social security numbers, tax return data, certain medical information, retirement account 
information and payroll data. Threats to security can take a variety of forms. Hackers may develop and deploy viruses, 
worms and other malicious software programs that attack our networks and data centers. Sophisticated organizations 
or individuals may launch targeted attacks to gain access to our networks, applications and confidential data, such as 
phishing attacks. 

We have implemented technical, physical, and administrative controls in order to protect personal and confidential 
information entrusted to us. In providing our services, we also rely on third-party service providers, such as insurance 
carriers, to process personal and confidential information about our clients, WSEs and employees. Through contractual 
provisions, we take steps to require that our service providers protect such information. However, we cannot guarantee 
the performance of our service providers and, ultimately, despite all of our efforts, threats to our IT infrastructure and 
our clients’ and WSEs’ data as these threats continue to grow in frequency, complexity and sophistication. While we, 
and our service providers, have programs in place to prevent, detect, and respond to data security incidents, these 
programs and our collective efforts may not always succeed. As a result, we may be required to invest significant 
additional resources to modify and enhance our information security to protect against such incidents.

Any cyber attack, unauthorized intrusion, insider theft, malicious software infiltration, network disruption or denial of 
service could result in disruption to our systems and services, product development delays, and the disclosure or 
misuse of personal and confidential information. This could have a material adverse effect on our business operations, 
result in liability or regulatory sanction or a loss of confidence in our ability to provide our services, or harm relationships 
with current or potential clients. Further, the cost of remediating any attack, breach or disclosure and costs associated 
with responding to litigation or regulatory investigations could have a material adverse effect on our business or reduce 
our operating margins. Maintaining the security of confidential WSE information is particularly important to us as a 
sponsor of employee benefit plans with access to certain personal health information. The manner in which we manage 
protected health information (PHI) is subject to HIPAA and the HITECH Act. To the extent possible, the health information 
we possess is anonymized and accessed through a secured third-party database. Although we maintain, and actively 
seek to improve, security measures and infrastructure designed to protect against unauthorized access to this sensitive 
data, cyber attacks and security breaches remain a significant threat to our business. Any security breach could result 
in the access, public disclosure, loss or theft of the confidential and personal data, including PHI, of our clients and 
WSEs, which could negatively affect our ability to attract new clients, cause existing clients to terminate their agreements 
with us, result in reputational damage and subject us to lawsuits, regulatory fines, or other actions or liabilities which 
could materially and adversely affect our business and operating results.

We are subject to various federal and state laws, rules, and regulations relating to the collection, use, and security of 
personal and confidential information. For example, most states and the District of Columbia have enacted breach 
notification laws that may require us to notify WSEs, clients, employees, or regulators in the event of unauthorized 
access to or disclosure of personal or confidential information. Complying with these various laws, and any new laws 
or regulations that may be promulgated, could cause us to incur substantial costs or require us to change our business 
practices  in  a  manner  adverse  to  our  business.  Changes  or  inconsistencies  in  interpretations  of  these  laws  and 
regulations and/or changes in enforcement priorities may result in significant penalties or liability for non-compliance.   

14

RISK FACTORS

Unexpected changes in workers' compensation and health insurance claims by worksite employees could harm our 
business.

Our insurance costs, which make up a significant portion of our overall costs, are impacted significantly by our WSEs’ 
health and workers' compensation insurance claims experience. We establish reserves to provide for the estimated 
costs of reimbursing our workers' compensation and health insurance carriers under our insurance policies, relying on 
third-party actuaries and our own experience, but the volume and severity of claims activity is inherently unpredictable. 
If we experience a sudden or unexpected increase or decrease in claim activity, our costs could increase or decrease, 
respectively. An increase in claim activity could make it more difficult to secure replacement insurance policies on 
competitive terms once our current policies expire. Estimating these reserves involves our consideration of a number 
of factors and requires significant judgment. If there is an unexpected increase or decrease in the severity or frequency 
of claims activity of our WSEs (including activity arising from any of a number of factors that affect claim activity levels, 
such as changes in general economic conditions, claims differing significantly from expectations, and terrorism, disease 
outbreaks or other catastrophic events), or if we subsequently receive updated information indicating insurance claims 
were higher or lower than previously estimated and reported, our insurance costs could be higher or lower, respectively, 
in that period or subsequent periods as we adjust our reserves accordingly, which could have a material adverse effect 
on our business. We have experienced both favorable and unfavorable insurance cost variability due to claims activity 
in the past and could have similar or worse experience in the future.

Some of our health insurance policies include risk-based policies that can limit our exposure for individual claims and 
our maximum aggregate claims exposure in each policy year. Refer to Note 1 in Part II, Item 8 of this Form 10-K for 
further discussion of these policies. We have experienced variability, and may experience variability in the future, in 
the amounts that we are required to pay for group health insurance expenses incurred by WSEs within our deductible 
layer under these risk-based policies, based on continually changing trends in the frequency and severity of claims. 
These historical trends may change, and other seasonal trends and variability may develop, which may make it more 
difficult for us to manage this aspect of our business and which may have a material adverse effect on our business. 

Our results of operations may fluctuate as a result of numerous factors, many of which are outside of our control.

Our future operating results are subject to quarterly variations based upon a variety of factors, many of which are not 
within our control, including, without limitation:

• 

• 

• 

• 

• 

• 

• 

• 

• 

• 

• 

• 

• 

the volume and severity of health and workers' compensation insurance claims by our WSEs, recorded as part of 
our insurance costs, and the timing of related claims information provided by our insurance carriers,

the amount and timing of our other insurance costs, operating expenses and capital expenditures,

the number of our new clients initiating service and the number of WSEs employed by each new client,

the retention, loss or merger of existing clients, 

reduction in the number of WSEs employed by existing clients,

the timing of client payments and payment defaults by clients,

costs associated with our acquisitions of companies, assets and technologies,

payments or drawdowns on our credit facility,

unanticipated expenses, such as litigation or other dispute-related settlement payments,

expenses we incur for geographic and service expansion,

changes in laws or adverse interpretation of laws increasing our regulatory compliance costs,

changes in our effective tax rate, and

the impact of new accounting pronouncements.

15

RISK FACTORS

Many of the above factors are discussed in more detail elsewhere in this “Risk Factors” section and in Part II, Item 7 
of this Form 10-K. Many of these factors are outside our control, and the variability and unpredictability of these factors 
have in the past and could in the future cause us to fail to meet our expectations and the expectations of investors and 
any industry analysts who cover our shares, which could result in a decline in our share price and reduced liquidity in 
our shares. In addition, the occurrence of one or more of these factors might cause our results of operations to vary 
widely,  which  could  lead  to  negative  impacts  on  our  margins,  short-term  liquidity  or  ability  to  retain  or  attract  key 
personnel, and could cause other unanticipated issues, including a downgrade of our shares by or change in opinion 
of industry analysts and a related decline in our share price. Accordingly, we believe that quarter-to-quarter and annual 
comparisons of our revenues, results of operations and cash flows may not be meaningful and should not be relied 
upon as an indication of our future performance.

Any failure in our business systems could reduce the quality of our business services, which could harm our reputation 
and expose us to liability.

Our business systems rely on the complex integration of numerous hardware and software subsystems to manage 
client transactions including the processing of employee, payroll and benefits data. These systems can be disrupted 
by, among other things, equipment failures, computer server or systems failures, network outages, malicious acts, 
software errors or defects, vendor performance problems, power failures, natural disasters, terrorist actions or similar 
events. Any  delay  or  failure  in  our  systems  that  impairs  our  ability  to  communicate  electronically  with  our  clients, 
employees, vendors or the government agencies to which we make tax and other filings on behalf of WSEs, or our 
ability to store or process data could harm our reputation and our business. For example, errors in our products and 
services, such as the erroneous denial of healthcare benefits or delays in making payroll, could expose our clients to 
liability claims from improperly serviced WSEs, for which we may be contractually obligated to provide indemnification.

In addition, the software, hardware and networking technologies we use must be frequently and rapidly upgraded in 
response to technological advances, competitive pressures consumer expectations and new and changing laws. To 
succeed, we need to effectively develop, or license from third parties, and integrate these new technologies as they 
become available to improve our services. We rely on enterprise software applications licensed from third parties that 
are upgraded from time to time. Any difficulties we encounter in adapting application upgrades to our systems could 
harm our performance, delay or prevent the successful development, introduction or marketing of new services. 

New products or upgrades may not be released according to schedule, or may contain defects when released. Difficulties 
in  integrating  new  technologies  could  result  in  adverse  publicity,  loss  of  sales,  delay  in  market  acceptance  of  our 
services, or client claims against us, any of which could harm our business. We could also incur substantial costs in 
modifying  our  services  or  infrastructure  to  adapt  to  these  changes.  In  addition,  we  could  lose  market  share  if  our 
competitors develop technologically superior products and services.

We have identified a material weakness in our internal control over financial reporting that could, if not remediated, 
result in a material misstatement in our financial statements.

In connection with the audit of our consolidated financial statements as of and for the year ended December 31, 2017, 
we have identified and concluded that we continue to have a material weakness relating to our internal control over 
financial reporting. A material weakness is a deficiency, or a combination of deficiencies, in internal control over financial 
reporting such that there is a reasonable possibility that a material misstatement of our annual or interim consolidated 
financial statements will not be prevented or detected on a timely basis. Refer to Part II, Item 9A in this Form 10-K for 
more details. While the material weakness described in that section creates a reasonable possibility that an error in 
financial reporting may go undetected, after extensive review and the performance of additional analysis and other 
procedures, no material adjustments, restatement or other revisions to our previously issued financial statements were 
required. 

As further described in Part II, Item 9A of this form 10-K below, we are taking specific steps to remediate a material 
weakness that we identified by implementing and enhancing our control procedures. This material weakness will not 
be remediated until all necessary internal controls have been implemented, repeatably tested and determined to be 
operating effectively. In addition, we may need to take additional measures, including system migration and automation, 
to address the material weakness or modify the remediation steps, and we cannot be certain that the measures we 
have taken, and expect to take, to improve our internal controls will be sufficient to address the issues identified, to 
ensure that our internal controls are effective or to ensure that the identified material weakness will not result in a 
material  misstatement  of  our  annual  or  interim  consolidated  financial  statements.  Implementing  any  appropriate 
changes to our internal controls may distract our officers and employees and require material cost to implement new 

16

RISK FACTORS

process or modify our existing processes. Moreover, other material weaknesses or deficiencies may develop or be 
identified in the future. If we are unable to correct material weaknesses or deficiencies in internal controls in a timely 
manner, our ability to record, process, summarize and report financial information accurately and within the time periods 
specified in the rules and forms of the U.S. Securities and Exchange Commission, will be adversely affected. This 
failure  could  negatively  affect  the  market  price  and  trading  liquidity  of  our  common  stock,  lead  to  delisting,  cause 
investors to lose confidence in our reported financial information, subject us to civil and criminal investigations and 
penalties, and generally materially and adversely impact our business and financial condition.

We have acquired, and may in the future acquire, other businesses and technologies, which can divert management's 
attention and create integration risks and other risks for our business.

We have completed numerous acquisitions of other businesses and technologies, and we expect that we will continue 
to grow through similar future acquisitions. Such acquisitions involve numerous other risks, including:

• 

• 

• 

• 

• 

• 

• 

• 

• 

• 

• 

identifying attractive acquisition candidates,

over-valuing and over-paying for acquisition candidates,

integrating the operations, systems, technologies, services and personnel of the acquired companies, including 
the migration of WSEs from an acquired company’s technology platform and legal service providers to ours,

establishing  or  maintaining  internal  controls,  procedures  and  policies  relating  to  the  acquired  systems  and 
processes, including the potential for actual or perceived control weaknesses associated with or arising from the 
acquisitions and integration of acquired systems,

diversion of management’s attention from other business concerns,

litigation resulting from activities of the acquired company, including claims from terminated employees, clients, 
former stockholders and other third parties,

insufficient revenues to offset increased expenses associated with the acquisitions and unanticipated liabilities of 
the acquired companies,

insufficient indemnification or security from the selling parties for legal liabilities that we may assume in connection 
with our acquisitions,

entering markets in which we have no prior experience and may not succeed,

potential loss of key employees of the acquired companies, and

impairment of relationships with clients and employees of the acquired companies or our clients and employees 
as a result of the integration of acquired operations and new management personnel.

If we fail to integrate newly acquired businesses effectively, we might not achieve the growth, service enhancement 
or operational efficiency objectives of the acquisitions, and our business, results of operations and financial condition 
could be harmed.

We may pay for acquisitions by issuing additional shares of our common stock, which would dilute our stockholders, 
or by issuing debt, which could include terms that restrict our ability to operate our business or pursue other opportunities 
and  subject  us  to  significant  debt  service  obligations.  We  may  also  use  significant  amounts  of  cash  to  complete 
acquisitions. To the extent that we complete acquisitions in the future, we likely will incur future amortization expenses 
associated with the acquired assets. We may also record significant amounts of intangible assets, including goodwill, 
which  could  become  impaired  in  the  future. Any  such  impairment  charges  would  adversely  affect  our  results  of 
operations.

17

RISK FACTORS

Our SMB clients are particularly affected by volatility in the financial and economic environment, which could harm our 
business.

Our clients are small and mid-sized businesses that we believe can be particularly susceptible to changes in the level 
of overall economic activity in the markets in which we operate. During periods of weak economic conditions, small 
business failures tend to increase and employment levels tend to decrease. Current or potential clients may react to 
weak or forecasted weak economic conditions by reducing employee headcount or wages, bonuses or benefits levels, 
any of which would affect our revenues, and may affect our margins, because we may be unable to reduce our operating 
expenses sufficiently enough or quickly enough to offset the drop in revenues. It is difficult for us to forecast future 
demand for our services due to the inherent difficulty in forecasting the direction, strength and length of economic 
cycles. These conditions may affect the willingness of our clients and potential clients to pay outside vendors for services 
like ours, and may impact their ability to pay their obligations to us on time, or at all. 

For example, as a result of macroeconomic factors, interest rates may become more volatile. Increased interest rate 
volatility could also negatively impact our clients' and prospects' access to credit. If businesses have difficulty obtaining 
credit, business growth and new business formation may be impaired, which could also harm our business. Even 
modest downturns in economic activity on a regional or national level could have a material adverse effect on our 
financial condition or results of operations.

In addition, it can be difficult to predict the impact of developments that are perceived as positive for SMBs. For example, 
the passage of the TCJA in December 2017, may create unexpected challenges or business incentives for our clients 
and fail to translate into increased demand for our services.

Our business and operations have experienced rapid growth in the past, and if we are unable to effectively manage 
future growth, our business and results of operations may suffer.

We have experienced rapid growth and have significantly expanded our operations in recent periods, which has placed 
a strain on our management and our administrative, operational and financial infrastructure. Managing this growth will 
continue to require further refinement to our operational, financial and management controls and reporting systems 
and  procedures  while  we  simultaneously  seek  to  effectively  recruit,  integrate,  train  and  motivate  new  corporate 
employees, retain our existing corporate employees, maintain the beneficial aspects of our corporate culture, effectively 
execute our business plan, satisfy the requirements of our existing clients, acquire new clients, and enhance the quality 
and scope of our services. These activities will require significant operating and capital expenditures and allocation of 
valuable  management  and  employee  resources,  and  we  expect  that  our  growth  will  continue  to  place  significant 
demands on our management and on our operational and financial infrastructure, all of which could have a material 
adverse effect on our business. If we fail to manage our growth effectively, our costs and expenses may increase more 
than we expect them to, which in turn could harm our business, financial condition and results of operations.

If our vertical strategy is unsuccessful, or if we are unable to manage our sales force effectively, we may not be able 
to grow our business at the rate that we anticipate.

We have developed an industry vertical business strategy and we plan to continue to devote significant resources and 
time in pursuit of this strategy. Under our industry vertical strategy, our sales force, product development, and service 
teams are focused on specific business sectors. We cannot assure you that our industry vertical approach will resonate 
with our existing and prospective clients, that we will target the right industries, that our vertical products will have all 
of the features most valuable to existing and prospective clients in those industries, or that we will implement our 
strategy in a timely and effective manner. If our vertical strategy is unsuccessful, our business may not grow at the 
rate that we anticipate, which could have a material adverse effect on our financial condition and results of operations.

We have experienced sales force attrition in the past and we rely on a well-trained sales force to promote our industry 
vertical strategy and sell our solutions. Competition for skilled sales personnel is intense, and we cannot assure you 
that we will be successful in attracting, training and retaining qualified sales personnel, or that our newly hired sales 
personnel, including our new sales leader, will function effectively, either individually or as a group. In addition, our 
newly hired sales personnel are typically not productive for some period of time following their hiring. This results in 
increased near-term costs to us relative to the sales contributions of these newly hired sales personnel. If we are unable 
to effectively train our sales force and benefit from greater productivity of our sales representatives, or if our sales force 
is otherwise unable to sell our solutions as we anticipate, our revenues likely will not increase at the rate that we 
anticipate, which could have a material adverse effect on our business, financial condition and results of operations.

RISK FACTORS

Most of our clients are concentrated in certain geographies and a relatively small number of industries, making us 
vulnerable to downturns in those geographies and industries.

Most of our clients are concentrated in certain geographies and operate in a relatively small number of industries, 
including the technology, life sciences, not-for-profit, professional services and financial services industries. As a result, 
if any of those geographic regions or specific industries suffers a downturn, the portion of our business attributable to 
clients in that region or industry could be adversely affected, which could have a material adverse effect on our financial 
condition or results of operations.

We are subject to legal proceedings that may result in adverse outcomes.

We are subject to claims, suits, government investigations, and proceedings arising from the ordinary course of our 
business. Refer to Note 13 in Part II, Item 8 of this Form 10-K for additional information about the legal proceedings 
we are currently involved in and future proceedings that we may face. Current and future legal proceedings may result 
in substantial costs and may divert management’s attention and resources, which may seriously harm our business, 
results of operations, financial condition and liquidity.

Changes in our income tax positions or adverse outcomes resulting from on-going or future tax audits, which could 
harm our business, operating results, financial condition and prospects.

Significant judgments and estimates are required in determining our provision for income taxes and other tax liabilities. 
Our provision for income taxes, results of operations and cash flows may be impacted if any of our tax positions are 
challenged and successfully disputed by the tax authorities. In determining the adequacy of our tax provision, we 
assess the likelihood of adverse outcomes that could result if our tax positions were challenged by the IRS and other 
tax authorities. The tax authorities in the U.S. regularly examine our income and other tax returns. Refer to Note 12 in 
Part  II,  Item  8  of  this  Form  10-K  for  additional  details  regarding  our  on-going  tax  examinations  and  disputes. The 
ultimate outcome of tax examinations and disputes cannot be predicted with certainty. Should the IRS or other tax 
authorities assess additional taxes as a result of these or other examinations, we may be required to record charges 
to operations that could have a material impact on our results of operations, financial position or cash flows.

Adverse changes in our insurance coverage, or in our relationships with key insurance carriers, could harm our business.

Our success depends in part on our ability to maintain competitive health and workers' compensation coverage options 
and insurance rates through well-known insurance carriers. If we are unable to maintain competitive insurance rates 
or obtain popular and desirable coverage plans through well-known insurance carriers, it could affect our ability to 
attract and retain clients, which would have a material adverse effect on our business. Where we sponsor insurance 
coverage and we are not responsible for any deductibles, our carriers set the premiums and the rates set by our carriers 
on these policies may not be competitive. Even where we sponsor insurance under which we are responsible for 
deductibles, we may not be able to control costs through the deductible layer in a way that would make our rates 
competitive. 

In addition, broad adoption of our services in certain geographies or industries may make it more difficult for us to 
obtain  competitive  health  and/or  workers'  compensation  insurance  rates  due  to  concentration  of  clients  within  a 
particular geography or industry. The loss of any one or more of our key insurance vendors in these areas, or our 
inability to partner with certain vendors that are better-known or more desirable to our clients or potential clients, could 
have a material adverse effect on our financial condition and results of operations.

There is significant competition for our clients and clients may terminate our services based on a variety of factors that 
are difficult for us to control, which can negatively impact our business.

We regularly experience client attrition due to a variety of factors, including cost, client merger and acquisition activity, 
increases in administrative and insurance service fees, client business failure, effects of competition and clients deciding 
to bring their HR administration in-house. Our standard client service agreement can be cancelled by us or by the client 
without penalty with 30 days’ prior written notice. Clients who intend to cease doing business with us often elect to do 
so effective as of the beginning of a calendar year. As a result, we have historically experienced our largest concentration 
of client attrition in the first quarter of each year. In addition, we experience higher levels of client attrition in connection 
with renewals of the health insurance coverage we sponsor for WSEs in the event that such renewals result in increased 
costs. If we were to experience client attrition in excess of our historic annual attrition rate, it could have a material 
adverse effect on our business, financial condition and results of operations.

19

RISK FACTORS

We  believe  the  principal  competitive  factors  in  our  market  include  client  satisfaction,  ease  of  client  setup  and  on-
boarding, breadth and depth of benefit plans, vertical market expertise, total cost of service, brand awareness and 
reputation, ability to innovate and respond to client needs rapidly, online and mobile solutions, and subject matter 
expertise. If we are unable to develop products that appeal to our clients, and that respond to the specific needs of 
our clients, on a cost-effective basis, our overall client satisfaction may decline and our reputation may suffer, which 
could lead us to experience greater rates of attrition and lower rates for on-boarding new clients, which could have a 
material adverse effect on our business.

The terms of our credit facility may restrict our current and future operations, which would impair our ability to respond 
to changes in our business and to manage our business.

Our credit facility contains, and any future indebtedness of ours would likely contain, a number of restrictive covenants 
that impose significant operating and financial restrictions on us subject to customary exceptions, including restricting 
our ability to:

• 

• 

• 

incur, assume or guarantee additional debt,

pay dividends or distributions or redeem or repurchase capital stock,

incur or assume liens,

•  make loans, investments and acquisitions,

• 

• 

• 

• 

• 

• 

• 

• 

engage in sales of assets and subsidiary stock,

enter into sale-leaseback transactions,

enter into certain transactions with affiliates,

enter into certain hedging agreements,

enter into new lines of business,

prepay certain indebtedness,

transfer all or substantially all of our assets or enter into merger or consolidation transactions with another person, 
and

enter into agreements that prohibit the incurrence of liens or the payment by our subsidiaries of dividends and 
distributions.

Our failure to comply with these restrictions and the other terms and conditions under our credit facility could result in 
a default, which in turn could result in the termination of the lenders’ commitments to extend further credit to us under 
our credit facility and acceleration of a substantial portion of our indebtedness then outstanding under our credit facility. 
If that were to happen, we may not be able to repay all of the amounts that would become due under our indebtedness 
or refinance our debt, which could materially harm our business and force us to seek bankruptcy protection. 

Atairos, our largest stockholder, may have significant influence over our Company, and the existing ownership of capital 
stock, and thus the voting control, remains concentrated in our executive officers, directors and their affiliates, which 
limits your ability to influence corporate matters.

On February 1, 2017, an entity affiliated with Atairos Group, Inc. (together with its affiliates, “Atairos”) became our 
largest  stockholder  when  it  acquired  the  shares  of  TriNet  common  stock  previously  held  by General Atlantic.  In 
connection with this transaction, we appointed Michael J. Angelakis, the Chairman and CEO of Atairos, to our board 
of  directors  and  agreed  to  nominate  Mr. Angelakis  or  another  designee  of Atairos  reasonably  acceptable  to  our 
Nominating  and  Corporate  Governance  Committee  for  election  at  future  annual  meetings  until Atairos’  beneficial 
ownership falls below 15% of our common stock. As of February 20, 2018, Atairos beneficially owned approximately 
28% of our outstanding common stock, and all of our directors, officers and their affiliates, including Atairos, beneficially 
own, in the aggregate, approximately 38% of our outstanding common stock. As a result, of the foregoing, Atairos, 
particularly when acting with our executive officers, directors and their affiliates who beneficially owned in the aggregate, 
approximately 38% of our outstanding common stock, will be able to exert substantial influence on all matters requiring 

20

RISK FACTORS

stockholder approval, including the election of directors and approval of significant corporate transactions, such as a 
merger  or  other  sale  of  our  company  or  its  assets. This  concentration  of  ownership  could  limit  the  ability  of  other 
stockholders to influence corporate matters and may have the effect of delaying or preventing a third party from acquiring 
control over us.

Our industry is highly competitive, which may limit our ability to maintain or increase our market share or improve our 
results of operations.

We face significant competition on a national and regional level from other professional employer organizations, as 
well as other existing, and potential, companies and industries that service, or may in the future service, client HR 
needs. Refer to the heading “Competition” under Item 1, Business, above for more details. Our competitors, regardless 
of industry, may have greater marketing and financial resources than we have, and may be better positioned than we 
are in certain markets. Increased competition in our industry could result in price reductions or loss of market share, 
any of which could harm our business. We expect that we will continue to experience competitive pricing pressure.

Moreover, we may not be successful in convincing potential clients that the use of our services is a superior, cost-
effective means of satisfying their HR obligations relative to the way in which they currently satisfy these obligations 
either  by  themselves  or  by  using  the  services  of  our  competitors.  If  we  cannot  compete  effectively  against  other 
professional employer organizations or against the alternative means by which companies meet their HR obligations, 
or if we are unable to convince clients or potential clients of the advantages of our offerings, our market share and 
business may suffer, resulting in a material, adverse effect on our financial condition and results of operations.

Market Information and Holders of Record

Our common stock has been listed on the New York Stock Exchange under the symbol “TNET” since March 2014. The 
following table sets forth for the periods indicated the high and low sales prices per share of our common stock as 
reported on the New York Stock Exchange for the quarters indicated below:

On February 20, 2018, the last reported sales price of our common stock on the New York Stock Exchange was $41.02
per share. As of February 20, 2018, we had 34 holders of record of our common stock per Computershare Trust Company 
N.A., our transfer agent. The actual number of stockholders is greater than this number of record holders, and includes 
stockholders who are beneficial owners, but whose shares are held in street name by brokers and other nominees. This 
number of holders of record also does not include stockholders whose shares may be held in trust by other entities. 

For information regarding our equity-based incentive plans, please refer to Part III, Item 12 of this Form 10-K.

Dividend Policy

We did not declare or pay cash dividends in 2017 or 2016. Payment of cash dividends, if any, in the future will be at the 
discretion of our board of directors and will depend on then-existing conditions, including our financial condition, operating 
results, contractual restrictions under our credit facility (refer to Note 8 in Item 8 of this Form 10-K), capital requirements, 
business prospects and other factors our board of directors may deem relevant.

Issuer Purchases of Equity Securities

We repurchased a total of approximately $44 million of our outstanding common stock in 2017 using existing cash and 
cash equivalents balances through our Rule 10b5-1 plan. In December 2017, our board of directors approved a $120 
million incremental increase to our ongoing stock repurchase program, resulting in approximately $136 million remaining 
available for repurchases under all authorizations approved by the board of directors as of December 31, 2017. Stock 
repurchases under the program are primarily intended to offset the dilutive effect of share-based employee incentive 
compensation.

     (B-2 term loan) and a $75 million revolving facility, and
   - A $190 million second lien seven-year-six-month term loan.

Non-GAAP Financial Measures

In addition to financial measures presented in accordance with U.S. Generally Accepted Accounting Principles (GAAP), 
we monitor other non-GAAP financial measures that we use to manage our business, make planning decisions, allocate 
resources and as performance measures in our executive compensation plan. These key financial measures provide 
an additional view of our operational performance over the long-term and provide useful information that we use in 
order to maintain and grow our business.

The presentation of these non-GAAP financial measures is used to enhance the understanding of certain aspects of 
our financial performance. It is not meant to be considered in isolation, superior to, or as a substitute for the directly 
comparable financial measures prepared in accordance with GAAP.

Net Insurance Service Revenues

• Insurance revenues less insurance costs.

• Is a component of Net Service Revenues.

• Provides a comparable basis of revenues on 
a  net  basis.  Professional  service  revenues 
are  represented  net  of  client  payroll  costs 
whereas  insurance  service  revenues  are 
presented  gross  of  insurance  costs  for

effectiveness  of  our  business  strategies  by 
excluding certain non-cash charges such as 
depreciation  and  amortization  that  have 
fluctuated  significantly  over  the  past  five 
years,  and  stock-based  compensation

Adjusted EBITDA

• Net income, excluding the effects of: 

- income tax provision, 
- interest expense, 
- depreciation, 
- amortization of intangible assets, 
- stock-based compensation expense and, 
- in 2014, secondary offering costs related

Adjusted Net Income

• Net income, excluding the effects of: 

- effective income tax rate (1),

- amortization of intangible assets, 
- non-cash interest expense (2), 
- debt prepayment premium, 
- in 2014, secondary offering costs related

As a of result changes in state income taxes from an increase in excludable income for state income tax purposes or state legislative changes, 
we have adjusted our non-GAAP effective tax rate to 41%, 43%, 42%, 40% and 40% for 2017, 2016, 2015, 2014 and 2013, respectively. 
These non-GAAP effective tax rates exclude the income tax impact from stock-based compensation, changes in uncertain tax positions and 
nonrecurring benefits or expenses from federal legislative changes.

MANAGEMENT'S DISCUSSION AND ANALYSIS

Item 7. Management’s Discussion and Analysis of Financial Condition and Results of 
Operations

Significant Developments in 2017

Our consolidated results for our 2017 fiscal year reflect continued progress for our vertical products and insurance 
service offerings combined with higher WSE enrollment growth within our medical plans and slower growth in insurance 
costs, which were primarily attributable to reduced health and workers' compensation costs.

In summary, we:

•  Made significant investments in our technology platform to provide our users with improved functionality, including 
online and mobile productivity tools, and to allow our platform to integrate more effectively with third party software 
applications. This improves our client experience and permits further operational scale in the future.

• 

• 

Launched and began on-boarding clients to TriNet Main Street, our vertical offering designed for clients in the 
hospitality, retail and manufacturing industries. During the third quarter, we started migrating existing clients from 
our legacy (SOI) platform onto our common TriNet platform. 

Leveraged our scale by decreasing administrative costs associated with our insurance programs. As a result of 
these efforts and our 2017 favorable insurance experience, we launched a fee credit initiative that was designed 
to reward certain clients. The total amount of credit was less than 0.5% of total 2017 revenue. Eligible clients will 
receive the fee credit in the first quarter of 2018.

•  Changed the contract terms with one of our health insurance carriers from a guaranteed-cost arrangement to an 
arrangement  that  continues  to  be  fully  insured,  but  where  we  will  be  responsible  for  reimbursement  of  claim 
payments within our deductible layer as further discussed below.

• 

Invested  significantly  in  improving  our  internal  control  environment  to  support  the  compliance  requirements  of 
Sarbanes-Oxley Act of 2002 (SOX).

Performance Highlights

Our financial revenue and earnings performance exceeded our expectations, which was primarily attributable to slower 
than expected growth in insurance costs. The insurance cost savings were driven by reduced administrative costs and 
lower than forecast per enrollee medical costs. Our per enrollee aggregate trailing twelve month medical cost trend 
(medical cost trend) was in the range of 3.5% to 4%. We attribute the lower medical cost trend to both lower medical 
utilization and reduced prescription drug price increases.

Our insurance service revenues benefited from 5% additional enrollment in our health insurance offerings. Insurance 
service revenue also benefited from our workers' compensation service revenue repricing efforts for certain clients 
based on their long term claim experience.

We experienced a decline in Average WSEs compared to 2016 due to our continued migration from legacy platforms 
to  our  common  TriNet  platform  and  due  to  moderated  new  customer  growth  as  we  launched  and  expanded  the 
functionality of TriNet Main Street.

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

In 2017, we:

• 

• 

served approximately 14,800 clients, co-employed approximately 325,000 WSEs, and our Total WSEs decreased 
4% over 2016

processed over $37.1 billion in payroll and payroll tax payments for our clients in 2017 with an increase of 8% over 
2016, 

30

MANAGEMENT'S DISCUSSION AND ANALYSIS

Our financial highlights for the 2017 year include:

•  Total revenues increased 7% to $3.3 billion, while Net Service Revenues increased 25% to $809 million,

•  Operating income increased 75% to $217 million,

• 

our effective tax rate decreased to 11%,

•  Net income increased 190% to $178 million, or $2.49 per diluted share, while Adjusted Net Income increased 62%

to $142 million,

•  Adjusted EBITDA increased 53% to $285 million, and

•  Cash provided by operating activities increased 70% to $253 million.

Our Technology

We made significant investments in our technology platform to provide our users with improved functionality, including 
online and mobile productivity tools, and to allow our platform to integrate more effectively with third party software 
applications. In addition, we invested in a common technology platform as it allows us to offer industry–specific solutions 
in a scalable manner while delivering frequent enhancements that benefit all clients. We continued to consolidate our 
remaining legacy acquired platform (SOI) onto our common TriNet platform.

For 2017, our systems development and programming costs were $45 million, representing 1% of our total revenues 
and 6% of our Net Service Revenues. Combined with our technology related capital expenditures, our total technology 
investment was $74 million, representing 2% of our total revenues and 9% of our Net Service Revenues. 

We plan to continue to invest to upgrade and improve technology offerings, including enhancements of our online 
interface and mobile applications to provide better client and individual WSE experience. 

Insurance

We are committed to utilizing our scale to improve the cost and service offerings in our competitive insurance services. 

We leverage the size and scale of our installed WSE-base to negotiate with both incumbent and new insurance providers 
in our major medical programs as well as property and casualty lines. Our negotiations with insurance providers and 
a one year suspension of a tax on health insurance premiums resulted in our reduction in our administrative costs.

While we continue to leverage our size with insurance carriers to negotiate further reductions in our administrative 
costs, we expect our medical cost trends to revert to long term averages in 2018. We will also expect the re-introduction 
of the healthcare tax on premiums we pay our insurance providers.

Our fully insured insurance plans are provided by third-party insurance carriers under risk-based or guaranteed-cost 
insurance policies. Under risk-based policies, 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. Under guaranteed-cost policies, our carriers establish the premiums and 
we are not responsible for any deductible.

Approximately 70% of our group health insurance costs related to risk-based plans. The remaining 30% of our group 
health insurance costs related to guaranteed-cost plans.

In October, we changed the contract terms with one of our health insurance carriers from a guaranteed-cost to a risk-
based plan. In 2018, with this new arrangement in effect, we expect that risk-based policies will represent approximately 
85% of our health insurance costs and guaranteed cost policies will represent approximately 15% of our health insurance 
costs.

We also introduced additional service and benefit offerings including a premier medical second opinion program as 
well as a new suite of complementary voluntary benefits. These voluntary benefits are intended to provide our WSEs 
with additional protections for unexpected life events. 

31

MANAGEMENT'S DISCUSSION AND ANALYSIS

Our Vertical Approach

We introduced our fifth TriNet vertical product, TriNet Main Street, to service the needs of industries such as hospitality, 
retail, and manufacturing. TriNet Main Street is designed to accommodate organizations with employee bases which 
include salaried, hourly, part time and seasonal workers, and typically operate in multiple states, locations, and facility 
types.  TriNet  Main  Street  delivers  time  and  attendance  expertise,  hiring  and  termination  expertise,  workers’ 
compensation safety consultants, and attractive benefit plans.

We believe our vertical approach is an important competitive differentiator for TriNet and delivers significant benefits 
to our clients. 

Revenues diverge by industry vertical due to pricing differences across our HR solutions and services and the degree 
to  which  clients  and  WSEs  elect  to  participate  in  our  solutions.  We  also  focus  on  pricing  strategies  and  product 
differentiation to maximize our revenue opportunities.

Our People

As we grow, we continue to invest in our corporate employees and their capabilities. 

We  increased  headcount  in  our  technology  and  client  service  functions  to  support  product  delivery  and  platform 
integration and support our migration of clients from legacy platforms to the TriNet platform. We also continued to invest 
in growing our sales functions, hiring and retaining sales representatives with industry experience. From 2016 to 2017, 
we incurred additional compensation costs of $41 million. 

We will continue to search, select and hire people to serve our current clients and find new clients as our business 
grows and add to our skills and capabilities in order to provide innovative HR solutions for our clients.

MANAGEMENT'S DISCUSSION AND ANALYSIS

Operating Metrics

Worksite Employees (WSE)

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

Average WSEs decreased 1% in 2017 but increased 8% in 2016. The decline in our Average WSE growth rate is a 
result of attrition, including attrition from migrating our clients to a common platform, partially offset by WSE growth in 
our established customer base. Furthermore, we moderated our new customer growth as we expanded the functionality 
of our new industry vertical, TriNet Main Street.

Anticipated revenues for future periods can diverge from Total WSEs due to pricing differences across our HR solutions 
and services and the degree to which clients and WSEs elect to participate in our solutions. As we present our growth 
by WSE, the additional volume growth we obtain from the different WSE participation in our major services or vertical  
products is reported as a change in mix.

In addition to driving the growth in WSE count, we also focus on pricing strategies and product differentiation to maximize 
our revenue opportunities. Average monthly total revenues per WSE, as a measure to monitor the success of such 
pricing strategies, has increased 8% in 2017 versus an increase of 7% in 2016.

34

MANAGEMENT'S DISCUSSION AND ANALYSIS

Revenues and Income

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

2017 - 2016 Commentary

Total revenues were $3.3 billion, a 7% increase from 2016:

• 

Insurance service revenues increased 8% over 2016 to $2.8 billion due to increased participation in our health 
plans combined with an increase in health insurance service fees per plan participant. 

•  Professional service revenues were $458 million, an increase of 3% over 2016.

Operating income was $217 million, a 75% increase from 2016, primarily due to improvement in our Net Insurance 
Service Revenues, partially offset by a 15% increase in other operating expenses to support our initiatives and additional 
costs associated with our internal control remediation efforts. Refer to the Other Operating Expenses section in this 
Results of Operations for further detail.

2016 - 2015 Commentary

Total revenues in 2016 were $3.1 billion, a 15% increase from 2015: 

• 

Insurance service revenues grew 16% over 2015 to $2.6 billion. 

•  Professional service revenues were $447 million, an increase of 11% over 2015.

Operating income was $124 million and 58% better than 2015, primarily due to improvement in our insurance service 
revenues, partially offset by an 18% increase in other operating expenses used to support our growth. Refer to the 
Other Operating Expenses section in this Results of Operations for further detail.

35

MANAGEMENT'S DISCUSSION AND ANALYSIS

Net Service Revenues

Net Service Revenues (total revenues less insurance costs) provides a comparable basis of revenues on a net basis, 
acts as the basis to allocate resources to different functions and helps us evaluate the effectiveness of our business 
strategies by each business function.

2017 - 2016 Commentary

Net Service Revenues were $809 million for 2017 representing a 25% increase from 2016. This was driven by an 
increase in Net Insurance Service Revenues, which grew 76% over 2016. Insurance service revenues per Average 
WSE increased 9%, while insurance costs per Average WSE increased 3%.

2016 - 2015 Commentary

Net Service Revenues was $646 million representing an 18% increase from 2015. Net Insurance Service Revenues 
represented 31% of Net Service Revenues and grew 37% over 2015 with insurance service revenues per Average 
WSE increasing by 8% but Insurance Costs per Average WSE increasing by only 6%.

36

MANAGEMENT'S DISCUSSION AND ANALYSIS

Professional Service Revenues (PSR)

Our clients are billed either based on a fee per WSE per month per transaction or on a percentage of the WSEs’ payroll. 
Payroll and payroll taxes processed is also an indicator of our PSR growth.

Our  investment  in  a  vertical  approach  provides  us  the  flexibility  to  offer  clients  in  different  industries  with  different 
services at different prices. 

We believe that this vertical approach will allow us to address specific needs for clients in different industries, which 
we believe will improve our revenue retention rate, but potentially reduces the value of using WSEs as the only leading 
indicator of future revenue performance.

37

MANAGEMENT'S DISCUSSION AND ANALYSIS

Insurance Service Revenues (ISR)

Insurance service revenues consist of insurance-related billings and administrative fees collected from clients and 
withheld from WSEs for workers' compensation insurance and health benefit insurance plans provided by third-party 
insurance carriers.

Insurance service revenues represented 86% of total revenues with growth of 8% in 2017 versus 16% in 2016. 

38

MANAGEMENT'S DISCUSSION AND ANALYSIS

Insurance Costs

Insurance costs include insurance premiums for coverage provided by insurance carriers, reimbursement of claims 
payments made by insurance carriers or third-party administrators, and changes in loss reserves related to our workers' 
compensation and health benefit insurance.

Insurance costs as a percentage of insurance service revenues decreased to 88% in 2017 from 92% and 94% in 2016 
and 2015, respectively.

39

MANAGEMENT'S DISCUSSION AND ANALYSIS

Other Operating Expenses (OOE)

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

We  manage  our  other  operating  expenses  and  allocate  resources  across  different  business  functions  based  on 
percentage of Net Service Revenues which has decreased to 69% in 2017 from 75% and 76% in 2016 and 2015, 
respectively. 

We have approximately 2,700 corporate employees as of December 31, 2017 in 49 offices across the U.S. Our corporate 
employees' compensation related expenses represent a majority of our operating expenses. Compensation costs for 
our corporate employees include payroll, payroll taxes, stock-based compensation, bonuses, commissions and other 
payroll  and  benefits  related  costs.  The  percentage  of  compensation  related  expense  to  other  operating  expense 
represents 65% of our operating expenses in 2017 and 70% in 2016 and 2015. These decreases are primarily due to 
increased non-compensation related costs associated with our vertical product development, platform integrations, 
and internal control remediation efforts. 

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

We also expect commission expense, which is included in sales and marketing, to decrease in 2018 with the planned 
adoption of new Accounting Standards Update (ASU) 2016-10 in the first quarter of 2018. We anticipate that incremental, 
non-perpetual client acquisition costs will be deferred and amortized to expense over the expected client tenure. Refer 
to Note 1, Item 8 of this Form 10-K for additional details surrounding the impact of this adoption.

40

MANAGEMENT'S DISCUSSION AND ANALYSIS

2017 - 2016 Commentary

Other  operating  expenses  increased  $72  million  or  15%  as  part  of  our  continued  investment  in  supporting  our 
infrastructure and our client service capabilities. Specific costs increased as follows: 

•  Total compensation costs increased $41 million or 13% primarily due to an increase in sales related compensation 
costs  associated  with  a  new  sales  performance  incentive  program  as  well  as  increased  headcount  related  to 
investments in technology to support product delivery and platform integration. 

•  Consulting expenses increased $12 million and included costs associated with enhancing our product offerings

•  Accounting and other professional fees increased $11 million in connection with significant time and resources 
required for our internal control remediation efforts and audit of our internal controls as required by Section 404 of 
the Sarbanes-Oxley Act of 2002.

•  Other expenses increased $8 million in 2017 due to additional compliance costs and external sales costs.

2016 - 2015 Commentary

Other  operating  expenses  increased  $72  million  or  18%  as  part  of  our  continued  investment  in  supporting  our 
infrastructure and our our client service capabilities. Specific costs increased as follows: 

•  Total compensation costs increased $41 million or 15% primarily due to increases in our

client services functions to support the growth and migration of clients from legacy platforms to TriNet 
platform, 

risk  services  functions  to  strengthen  our  insurance  business  management  by  hiring  new  leaders  and 
actuarial teams,

technology function to support product delivery and platform integration, and 

other supporting functions as a result of increased operational and compliance requirements for a growing 
public company.

•  Consulting expenses increased $9 million and included costs associated with reviewing and administering our 

insurance programs, as well as consulting firms engaged in enhancing our product offerings.

•  Accounting and other professional fees increased $8 million in primarily as a result of the professional fees to 

support our internal control remediation efforts.

•  Other expenses increased $14 million in 2016 and included office leases and IT infrastructure costs to support the 

increased operational requirements.

41

 
 
 
 
MANAGEMENT'S DISCUSSION AND ANALYSIS

Depreciation

Depreciation expense increased 45% to $28 million in 2017 and 32% to $19 million in 2016, as a result of our additional 
investment in technology products and platforms and the associated depreciation of those assets. 

Amortization of Intangible Assets

Amortization of intangible assets represents costs associated with acquired companies' developed technologies, client 
lists, trade names and contractual agreements. Amortization expense decreased 67% to $5 million in 2017 and 59% 
to $16 million in 2016, as a result of the 2016 revision to the expected useful life of certain client lists and trademarks 
primarily related to our previous acquisitions. 

Other Income (Expense)

Other income (expense) which consists primarily of interest expense under our credit facility offset by interest and 
dividend income from investments, decreased 10% to $17 million in 2017 and increased 7% to $20 million in 2016. 
The decrease in 2017 was primarily due to an increase in yields on our invested cash and cash equivalents , while the 
increase in 2016 was primarily due to the write-off of debt issuance costs resulting from the refinance of our term loan 
in July 2016.

We may seek to amend our credit facility when appropriate and if available terms become more favorable. We may 
also seek additional borrowings to fund acquisitions, accelerate the payment of principal on outstanding debt, or for 
other business purposes. As such, our interest expense may fluctuate as a percentage of our total revenues from 
period to period depending on the timing of those borrowing and or repayment activities.

42

MANAGEMENT'S DISCUSSION AND ANALYSIS

Provision for Income Taxes

Our effective tax rates (ETR) were 11%, 41% and 47% for the years ended December 31, 2017, 2016 and 2015, 
respectively. 

2017 - 2016 Commentary

Our ETR decreased 30% in 2017 from 41% in 2016 primarily due to the following:

• 

• 

• 

• 

• 

20% decrease attributable to revaluation of deferred taxes resulting from federal legislative changes pursuant to 
the TCJA additionally described in Note 12, Item 8 of this Form 10-K,

8% decrease due to a discrete tax benefit from recognizing excess tax benefits from stock-based compensation,

5% increase due to changes in uncertain tax positions (UTP) and exposures to ongoing tax examinations,

4% decrease resulting from the recognition of Section 199 benefits and decreased nondeductible expenses, and 

3% decrease related to tax credits and excludable income for state tax purposes.

2016 - 2015 Commentary

Our ETR decreased 6% in 2016 from 47% in 2015 primarily due to the following:

• 

• 

• 

6% decrease attributable to revaluation of deferred taxes resulting from state legislative changes enacted in 2015,

2% decrease in state income taxes from an increase in excludable income for state income tax purposes,

1% decrease from discrete benefits recorded in 2016 associated with prior year state income tax expense resulting 
from a state tax return to provision (RTP) adjustment relating to audit premiums paid for workers' compensation 
insurance, partially offset by

• 

2% increase from net operating loss adjustment recorded in 2015.

43

MANAGEMENT'S DISCUSSION AND ANALYSIS

Liquidity and Capital Resources 

Liquidity

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

WSE related assets and liabilities primarily consist of current assets and current liabilities resulting from transactions 
directly  or  indirectly  associated  with  WSEs,  including  payroll  and  related  taxes  and  withholdings,  our  sponsored 
insurance programs, and other benefit programs. Our cash flows related to WSE payroll and benefits is generally 
matched by advance collection from our clients which is reported as payroll funds collected within WSE related assets. 

We report our corporate cash and cash equivalents on the consolidated balance sheets separately from WSE related 
assets. We rely on our corporate cash and cash equivalents and cash from operations to satisfy our operational and 
regulatory requirements and to fund capital expenditures. We believe that we have sufficient corporate liquidity and 
capital resources to satisfy future requirements and meet our obligations to clients, creditors and debt holders.

Our liquid assets are as follows:

We had corporate cash and cash equivalents of $336 million and $184 million as of December 31, 2017 and 2016, 
respectively. The increase was primarily due to the cash generated from operations during 2017. We believe that our 
existing corporate cash and cash equivalents, working capital and cash provided by operating activities will be sufficient 
to meet our working capital and capital expenditure needs for at least the next 12 months. 

We manage our sponsored benefit and workers' compensation insurance obligations by maintaining funds in restricted 
cash, cash equivalents and investments as collateral. As of December 31, 2017, we had $170 million of restricted 
cash, cash equivalents and investments included in WSE related assets and $162 million of marketable securities 
designated as long-term restricted cash, cash equivalents and investments on the consolidated balance sheets. These 
collateral amounts are generally determined at the beginning of each plan year and we may be required by our insurance 
carriers to adjust the balance when facts and circumstances change. We regularly review our collateral balances with 
our insurance carriers, and anticipate funding further collateral as needed based on program development.

Capital Resources

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 operations, our borrowing capacity under our revolving credit 
facility and the potential issuance of debt or equity securities through our filed shelf registration statement.

In July 2016, we refinanced our existing tranche B term loan, originally scheduled to mature in July 2017, with tranche 
A-2  term  loans,  pursuant  to  an  amendment  to  the  Amended  and  Restated  First  Lien  Credit  Agreement  (Credit 
Agreement). As of December 31, 2017, $425 million of the term loans were outstanding including a $303 million term 
loan A at 3.95% per annum and $122 million term loan A-2 at 3.83% per annum maturing in July 2019.

We also have available a $75 million revolving credit facility. The total unused portion of the revolving credit facility 
was $60 million as of December 31, 2017. This revolving credit facility is expected to be used for working capital and 
other general corporate purposes.

MANAGEMENT'S DISCUSSION AND ANALYSIS

Uses of Funds

In 2017, we repurchased approximately 1,549,434 shares of our common stock for $44 million. As of December 31, 
2017, $136 million remained available for repurchase under the program, which is not subject to an expiration date. 
We also used $38 million for debt repayment and $38 million to fund capital expenditures, primarily associated with  
software and hardware investments, in 2017.

Cash Flows

We generated positive cash flows from operating activities during 2017, 2016 and 2015. We also have borrowing 
capacity under our revolving credit facility and the potential to generate cash through the issuance of our debt or equity 
securities, to meet short-term funding requirements. The following table presents our cash flow activities for the stated 
periods:

The period-to-period fluctuation in cash provided by operating activities is primarily driven by the 192% increase in our 
net income, a decrease in payments of our tax liabilities, decreases in collateral paid to our insurance carriers, partially 
offset by changes in deferred tax liabilities primarily associated with the revaluation of deferred taxes resulting from 
federal legislative changes pursuant to the TCJA.

2016 - 2015 Commentary

Cash provided by operating activities remained fairly consistent. The period-to-period fluctuation included an increase 
in payments of our tax liabilities, an increase of collateral paid to insurance carriers, an increase in our net income, 
increases in our deferred tax liabilities, and changes in other operating assets and liabilities. Changes in other operating 
assets and liabilities is primarily driven by the timing of payments related to WSE related assets and liabilities, and our 
accounts payable and accrued expenses related to our trade creditors, and corporate employee compensation related 
payables.

MANAGEMENT'S DISCUSSION AND ANALYSIS

We expect our net cash provided by operating activities to fluctuate significantly with the planned adoption of ASU 
2016-18 - Statement of Cash Flows (Topic 230): Restricted Cash in the first quarter of 2018 as changes in our restricted 
cash and cash equivalents balances will no longer be included within operating cash activities. For more information 
about the effects of this planned adoption, refer to Note 1 in Item 8 of this Form 10-K. 

Furthermore, we expect our tax payments to increase in 2018 due to our inability to defer taxes as a result of new 
restrictions in TCJA that recognize income for tax purposes in the same period as our financial statements.

Investing Activities

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

Capital expenditures have been investments in our software and hardware to introduce new products, enhance existing 
products and platforms, as well as platform integrations. In 2017, we made significant investments in our technology 
platform to provide our users with improved functionality, including online and mobile productivity tools, and to allow 
our platform to integrate more effectively with third party software applications. In July 2017, we launched and began 
onboarding  clients  to  TriNet  Main  Street,  our  vertical  offering  designed  for  clients  in  the  hospitality,  retail  and 
manufacturing industries. In 2016, we introduced TriNet Technology, TriNet Nonprofit, and TriNet Financial Services 
vertical products. In addition, we completed integrating our legacy platforms from acquisitions into the TriNet platform. 
We expect capital investments in our software and hardware to continue in the future. 

We primarily invest funds held as collateral to satisfy our long-term obligation towards the workers' compensation 
liabilities in U.S. long-term treasuries. Such investments are classified as available for sale investments and included 
as restricted cash, cash equivalents and investments in the balance sheet. We review the amount of investment and 
the anticipated holding period is regularly in conjunction with our estimated long-term workers' compensation liabilities 
and anticipated claims payment trend.

As of December 31, 2017, we held approximately $1.4 billion in restricted long-term and short-term accounts. We 
intend to prudently invest some or all of these funds and other amounts available to us within the framework of our 
investment policy and guidelines to generate interest income.

MANAGEMENT'S DISCUSSION AND ANALYSIS

Financing Activities

Net cash used in financing activities consisted primarily of repurchases of our common stock and repayment of debt.

The board of directors from time to time authorizes stock repurchases of our outstanding common stock primarily to 
offset dilution from the issuance of stock under our equity-based incentive plan and employee stock purchase plan. 
Refer to Note 9 in Item 8 of this Form 10-K for details of our equity plans. As of December 31, 2017, approximately 
$136 million remained available for repurchase under all authorizations by the board of directors.

Historically we funded business acquisitions and special dividends through borrowings under credit facilities which 
may fluctuate from period to period. We will seek to amend the current credit facilities as they expire, as needed by 
the business or if market conditions become more favorable, with interest rates or terms that may not necessarily be 
more favorable than the current interest rates or terms.

The Credit Agreement contains customary representations and warranties and customary affirmative and negative 
covenants applicable to us and our subsidiaries. It also contains financial covenants that require us to maintain: (1) a 
minimum consolidated interest coverage ratio of at least 3.50 to 1.00 and (2) a maximum total leverage ratio of 3.75
to 1.00 through December 31, 2017 and 3.50 to 1.00 thereafter. As of December 31, 2017, we were in compliance 
with these financial covenants.

In order to meet various states’ licensing requirements and maintain accreditation by the ESAC, we are subject to 
various minimum working capital and net worth requirements. As of December 31, 2017 and 2016, we believe we have 
fully complied in all material respects with all applicable state regulations regarding minimum net worth, working capital 
and all other financial and legal requirements. Further, we have maintained positive working capital throughout each 
of the periods covered by the financial statements.

MANAGEMENT'S DISCUSSION AND ANALYSIS

(4) Our purchase obligations primarily consist of software licenses, consulting and maintenance agreements, and sales and marketing events 
pertaining to various contractual agreements.

(5) Our uncertain tax positions primarily pertain to tax credits and other related reserves, including interest and penalties.

In the normal course of business, we make representations and warranties that guarantee the performance of services 
under service arrangements with clients. Historically, there have been no material losses related to such guarantees. 
In addition, we have entered into indemnification agreements with our officers and directors, which require us to defend 
and, if necessary, indemnify these individuals for certain pending or future legal claims as they relate to their services 
provided to us. Such indemnification obligations are not included in the table above.

Off-Balance Sheet Arrangements

As of December 31, 2017, we did not have any material off-balance sheet arrangements that are reasonably likely to 
have a current or future effect on our financial condition, results of operations, liquidity, capital expenditures or capital 
resources.

Critical Accounting Judgments and Estimates

Our consolidated financial statements are prepared in accordance with U.S. 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 Item 8 of this Form 10-K.

Recent Accounting Pronouncements

Refer to Note 1 in Item 8 of this Form 10-K for additional information related to recent accounting pronouncements.

Insurance Loss Reserves

We purchase fully insured 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 
insurance reserves including both known and incurred but not reported (IBNR) costs. 

As workers' compensation costs for a particular period are not known for many years after the losses have occurred 
these  loss  reserves  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 estimates of our workers' compensation and health 
benefits loss reserves. The loss reserve studies performed by these qualified actuaries analyze historical claims data 
to develop a range of potential ultimate losses using loss development, expected loss ratio and frequency/severity 
methods in accordance with Actuarial Standards of Practice. Loss methods are applied to classes or segments of the 
loss data organized by policy year and risk class. 

Key judgments and evaluations in arriving at loss estimates by segment and the reserve 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 loss development factor (LDF) used in these models,

the effect of any changes to claims handling and payment processes,

evaluation of loss (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 loss 
reserves. Where adjustments are necessary these are recorded in the period in which the adjustments are identified.

48

MANAGEMENT'S DISCUSSION AND ANALYSIS

Workers' Compensation Loss Reserves 

Under our policies, we are responsible for reimbursing the insurance carriers for workers' compensation losses up to 
$1 million per claim occurrence (Deductible Layer). We use external actuaries to evaluate, review and recommend 
workers' compensation loss reserves on a quarterly basis. The data is segmented by class and state and analyzed by 
policy year; states where we have small exposure are aggregated into a single segment.

We use a combination of loss development, expected loss ratio and frequency/severity methods which include the 
following inputs, assumptions and analytical techniques:

•  TriNet's historical frequency and severity of workers' compensation claims experience, exposure data and industry 

loss experience, 

inputs of WSEs’ job responsibilities and location,

estimates of future cost trends to establish expected loss ratios for subsequent accident years, 

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 

• 

• 

• 

• 

loss development factors to project the reported losses for each accident year to an ultimate basis. 

Final claim settlements may vary materially from the present estimates, particularly when those payments may 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. Certain assumptions used in estimating these reserves are highly judgmental. Our 
loss reserves, results of operations and financial condition can be materially impacted if actual experience differs from 
the assumptions used in establishing these reserves. 

We believe that our estimate of workers' compensation loss reserves are most sensitive to loss development factors 
given  the  long  reporting  and  paid  development  patterns  for  our  workers'  compensation  loss  costs.  Our  reserving 
methods rely on these loss development factors and an estimate of future cost trend.

The following table illustrates the sensitivity of changes in the loss development factor on our year end estimate of 
insurance reserves (in millions of dollars):

Change in loss development factor
-5.0%

Change in insurance costs

We sponsor and administer a number of fully insured, risk based employee benefit plans, including group health, dental, 
vision and life insurance as an employer plan sponsor under section 3(5) of the ERISA. Approximately 70% of our 
2017 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 loss reserves 
include estimates of reported losses and claims incurred but not yet paid (IBNP). Data is segmented and analyzed by 
insurance carrier. 

To estimate health benefits loss reserves we use a number of inputs, assumptions and analytical techniques:

•  TriNet historical loss claims payment patterns and medical cost trend rates, 

• 

• 

current period claims costs and claims reporting patterns (completion factors), and

plan enrollment. 

49

MANAGEMENT'S DISCUSSION AND ANALYSIS

These reserves may vary in subsequent quarters from the amount estimated. Our loss reserves, results of operations 
and  financial  condition  can  be  materially  impacted  if  actual  experience  differs  from  our  key  assumptions  used  in 
establishing these reserves.

We believe that our year end estimate of health benefits loss reserves are most sensitive to changes in medical claim 
costs in the markets in which participating WSEs reside (medical cost trend) and our estimate of paid costs to carriers 
as a percentage of the expected ultimate costs to carriers (completion factors).

A 250 basis point increase in the medical cost trend would increase our year end health benefit loss reserves by 
approximately $11 million, and a 50 basis point decrease in completion factors would increase our year end health 
benefit loss reserves by approximately $8 million.

QUANTITATIVE AND QUALITATIVE DISCLOSURES

Item 7A. Quantitative and Qualitative Disclosures About Market Risk

We  had  restricted  cash  equivalents,  investments  and  interest  bearing  receivables  in  connection  with  workers' 
compensation premiums totaling $261 million as of December 31, 2017. Included in this amount were $257 million in 
money market mutual funds, U.S. Treasuries and commercial paper. Our investments are made for capital preservation 
purposes and these interest-earning instruments carry a degree of interest rate risk. Our future investment income 
may fall short of expectations due to changes in interest rates or we may suffer losses in principal if we are forced to 
sell securities prior to maturity or declines in fair value are determined to be other-than-temporary. Fluctuations in the 
value of our investment securities caused by a change in interest rates (gains or losses on the carrying value) are 
recorded in other comprehensive income, and are realized only if we sell the underlying securities. To date, fluctuations 
in interest income have not been significant. 

We had total outstanding indebtedness of $425 million as of December 31, 2017, of which $42 million is due within 12 
months. We are exposed to market risk from changes in interest rates on our debt. Depending upon the borrowing 
option chosen, the interest charged is generally based upon the prime lending rate or London Inter-bank Offered Rate 
(LIBOR) plus an applicable margin. If interest rates in effect at December 31, 2017 increased or decreased 100 basis 
points, our interest expense for 2018 and 2019 would correspondingly increase or decrease by $5 million, respectively.

FINANCIAL STATEMENTS

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM 

To the shareholders and the Board of Directors of TriNet Group, Inc. 

Opinion on the Financial Statements

We have audited the accompanying consolidated balance sheets of TriNet Group, Inc. and subsidiaries (the "Company") 
as of December 31, 2017 and 2016, and the related consolidated statements of income and comprehensive income, 
stockholders’ equity (deficit), and cash flows for the years then ended, and the related notes and the schedule listed 
in the Index at Item 15 (collectively referred to as the "financial statements"). In our opinion, the financial statements 
present fairly, in all material respects, the financial position of the Company as of December 31, 2017 and 2016, and 
the results of operations and its cash flows for the years then ended, in conformity with accounting principles generally 
accepted in the United States of America.

We have also audited, in accordance with the standards of the Public Company Accounting Oversight Board (United 
States) (PCAOB), the Company's internal control over financial reporting as of December 31, 2017, based on criteria 
established in Internal Control - Integrated Framework (2013) issued by the Committee of Sponsoring Organizations 
of the Treadway Commission and our report dated February 27, 2018, expressed an adverse opinion on the Company's 
internal control over financial reporting because of a material weakness.

Basis for Opinion

These financial statements are the responsibility of the Company's management. Our responsibility is to express an 
opinion on the Company's financial statements based on our audits. We are a public accounting firm registered with 
the PCAOB and are required to be independent with respect to the Company in accordance with the U.S. federal 
securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.

We conducted our audits in accordance with the standards of the PCAOB. Those standards require that we plan and 
perform  the  audit  to  obtain  reasonable  assurance  about  whether  the  financial  statements  are  free  of  material 
misstatement, whether due to error or fraud. Our audits included performing procedures to assess the risks of material 
misstatement of the financial statements, whether due to error or fraud, and performing procedures that respond to 
those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures 
in the financial statements. Our audits also included evaluating the accounting principles used and significant estimates 
made by management, as well as evaluating the overall presentation of the financial statements. We believe that our 
audits provide a reasonable basis for our opinion.

FINANCIAL STATEMENTS

TRINET GROUP, INC.
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

NOTE 1. DESCRIPTION OF BUSINESS AND SIGNIFICANT ACCOUNTING POLICIES

Description of Business

TriNet Group Inc. (TriNet or we, our and us), a professional employer organization (PEO) founded in 1988, provides 
comprehensive  human  resources  (HR)  solutions  for  small  to  midsize  businesses  (SMBs)  under  a  co-employment 
model. These HR solutions include bundled services, such as multi-state payroll processing and tax administration, 
employee benefits programs, including health insurance and retirement plans, workers' compensation insurance and 
claims  management,  employment  and  benefit  law  compliance,  and  other  services.  Through  the  co-employment 
relationship, we are the employer of record for most administrative and regulatory purposes, including: 

• 

• 

• 

• 

compensation through wages and salaries,

employer payroll-related taxes payment, 

employee payroll-related taxes withholding and payment,

employee benefit programs including health and life insurance, and others, and 

•  workers' compensation coverage. 

Our clients are responsible for the day-to-day job responsibilities of the worksite employees (WSEs).

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

Basis of Presentation

Our consolidated financial statements are prepared in conformity with generally accepted accounting principles in the 
United States of America (GAAP). All intercompany accounts and transactions have been eliminated in consolidation. 

Use of Estimates

The preparation of financial statements in conformity with GAAP requires us to make estimates and assumptions that 
affect certain reported amounts and related disclosures. Significant estimates include: 

• 

• 

• 

• 

• 

• 

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

health insurance loss reserves,

liability for insurance premiums payable,

impairments of goodwill and other intangible assets,

income tax assets and liabilities, and 

liability for legal contingencies.

These estimates are based on historical experience and on various other assumptions that we believe to be reasonable 
from the facts available to us. Some of the assumptions are highly uncertain at the time of estimation. To the extent 
actual experience differs from the assumptions used, our consolidated financial statements could be materially affected.

59

FINANCIAL STATEMENTS

Revenue Recognition 

Professional service revenues represent fees charged to clients for processing payroll-related transactions on behalf 
of our clients, access to our HR expertise, employment and benefit law compliance services and other HR related 
services. Professional service revenues are recognized in the period the services are rendered and earned under 
service arrangements with clients, where service fees are fixed or determinable, and collectability is reasonably assured.  
Clients execute annual service contracts with us that automatically renew. Generally, our clients may cancel these 
contracts with thirty days' notice and we may cancel these contracts with thirty days' notice. 

We are not considered the primary obligor with respect to WSEs payroll and payroll tax payments and therefore, these 
payments are not reflected as either revenue or expense in our consolidated statements of income and comprehensive 
income. 

We generally charge an upfront non-refundable set-up fee which is recognized on a straight-line basis over the estimated 
average client tenure. 

Insurance service revenues consist of insurance-related billings and administrative fees collected from clients and 
withheld from WSEs for workers' compensation insurance and health benefit insurance plans provided by third-party 
insurance carriers. Insurance service revenues are recognized over the period the insurance coverage is provided 
and where collectability is reasonably assured.

The professional service revenues and insurance service revenues are each considered separate units of accounting 
for administrative services and insurance related benefits billed to the majority of our clients. For clients billed through 
a bundled invoice, the selling price of significant deliverables is determined based on the best estimate of the selling 
price. 

Insurance Costs 

Our fully insured insurance plans are provided by third-party insurance carriers under risk-based or guaranteed-cost 
insurance policies. Under risk-based policies, 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. Under guaranteed-cost policies, our carriers establish the premiums and 
we are not responsible for any deductible.

Insurance costs include insurance premiums for coverage provided by insurance carriers, reimbursement of claims 
payments made by insurance carriers or third-party administrators, and changes in loss reserves related to our workers' 
compensation and health benefit insurance. 

At policy inception, annual workers' compensation premiums are estimated by the insurance carriers based on projected 
wages over the duration of the policy period and the risk categories of the WSEs. As actual wages are realized, premium 
expense recorded may differ from estimated premium expense, creating an asset or liability throughout the policy year. 
Such asset or liability is reported on our consolidated balance sheets as prepaid insurance premiums or insurance 
premiums payable, respectively.

Workers' Compensation Loss Reserves 

We have secured fully insured workers' compensation insurance policies with insurance carriers for our clients and 
WSEs that obligate us to reimburse the insurance carriers for losses up to $1 million per claim occurrence (deductible 
layer).  Workers'  compensation  insurance  reserves  represent  our  liability  for  unpaid  losses  and  loss  adjustment 
expenses. These  reserves  are  established  to  provide  for  the  estimated  ultimate  costs  of  paying  claims  within  the 
deductible layer in accordance with worker's compensation insurance policies. These reserves include estimates for 
reported and incurred but not reported (IBNR) losses, case reserves on reported claims, and expenses associated 
with processing and settling the claims. In establishing these reserves, we use an independent actuary to provide an 
estimate of undiscounted future cash payments that would be made to settle the claims based upon:

•  TriNet's historical loss experience, exposure data, and industry loss experience,

• 

• 

• 

inputs including WSE job responsibilities and location,

historical frequency and severity of workers' compensation claims,

an estimate of future cost trends to establish expected loss ratios for subsequent accident years, 

60

FINANCIAL STATEMENTS

• 

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 

• 

loss development factors to project the reported losses for each accident year to an ultimate basis. 

We assess the workers' compensation loss reserves on a quarterly basis. For each reporting period, changes in the 
actuarial  methods  and  assumptions  resulting  from  changes  in  actual  claims  experience  and  other  trends  are 
incorporated into the workers' compensation loss reserves. Adjustments to previously established reserves are reflected 
in the results of operations for the period in which the adjustment is identified. Such adjustments could be significant, 
reflecting any variety of new adverse or favorable trends. Accordingly, final claim settlements may vary materially from 
the present estimates, particularly when those payments may not occur until well into the future. In our experience, 
plan years related to workers' compensation programs may take ten years or more to be settled.

We do not discount workers' compensation loss reserves. Claim costs expected to be paid within one year are recorded 
as workers' compensation reserves included in short-term WSE related liabilities. Claim costs expected to be paid 
beyond one year are included in long-term liabilities. 

Insurance carriers are responsible for administering and paying claims. We are responsible for reimbursing each carrier 
up to a deductible limit per occurrence. 

We have collateral agreements with various insurance carriers where either we retain custody of funds in trust accounts 
which we record as restricted cash and cash equivalents, or remit funds to carriers. Collateral whether held by us, or 
the  carriers,  is  used  to  settle  our  insurance  and  claim  deductible  obligations  to  them.  Collateral  requirements  are 
established at the policy year and are re-assessed by each carrier annually. Based on the results of each assessment, 
additional collateral may be required for or paid to the carrier or collateral funds may be released or returned to the 
company. Collateral paid to carriers, by agreement permits net settlement of obligations against collateral held, which 
we record net of our loss reserves (Carrier Collateral Offset). We offset Carrier Collateral Offset against our obligation 
due within the next 12 months before applying against long term obligations. Collateral balances in excess of loss 
reserves are recorded as workers' compensation collateral receivable, in WSE related assets or in long-term assets.

Health Benefits Loss Reserves 

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 Employee Retirement Income Security Act (ERISA). 
In 2017, a majority of our group health insurance costs related to risk-based plans. Our remaining group health insurance 
costs were for guaranteed-cost policies. 

Health benefits loss reserves 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 reserves 
include estimates for reported losses, plus estimates for claims incurred but not paid. We assess reserves 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 the subsequent period. These 
prepaid balances by agreement permit net settlement of obligations and offset the health benefits loss reserves or 
when the prepaid is in excess of our recorded liability the net asset position is included in WSE related assets.

Under certain policies, based on plan performance, we may be entitled to receive refunds of premiums which we 
recognize in accordance with the policy terms. We estimate these refunds based on premium and claims data and 
record as a reduction in the insurance costs on the consolidated statements of income and comprehensive income 
and prepaid health plan expenses in WSE related assets on the consolidated balance sheets. As of December 31, 
2017 and 2016, we had $11 million and $9 million, respectively, included within WSE related assets as prepaid insurance 
premiums. 

Cash and Cash Equivalents

Cash and cash equivalents include bank deposits and short-term, highly liquid investments. Investments with original 
maturity dates of three months or less are considered cash equivalents.

61

FINANCIAL STATEMENTS

Restricted Cash, Cash Equivalents and Investments

Restricted cash and cash equivalents presented on our consolidated balance sheets represents our corporate cash 
and cash equivalents in trust accounts functioning as security deposits for our insurance carriers. These deposits are 
not used for settling insurance premiums or claims payments. 

WSE related assets also includes restricted cash, cash equivalents and investments held in trust for current and future 
premium and claim obligations with our insurance carriers. Amounts are held in trust according to the terms of the 
relevant insurance policies and by the local insurance regulations of the jurisdictions in which the policies are in force. 

Investments 

We have investments primarily in marketable securities including U.S. treasuries, which are classified as available for 
sale and are carried at estimated fair value. Unrealized gains and losses are reported as a component of accumulated 
other  comprehensive  income  (loss),  net  of  deferred  income  taxes. The  amortized  cost  of  marketable  securities  is 
adjusted for amortization of premiums and accretion of discounts from the date of purchase to maturity or sale. Such 
amortization  is  included  in  interest  income  as  an  addition  to  or  deduction  from  the  coupon  interest  earned  on  the 
investments.  We  use  the  specific  identification  method  to  determine  the  realized  gains  and  losses  on  the  sale  of 
available for sale securities. Realized gains and losses are included in other income in the accompanying consolidated 
statements of income and comprehensive income. 

We assess our investments for an other-than-temporary impairment loss due to a decline in fair value or other market 
conditions. We review several factors to determine whether a loss is other than temporary, such as the length and 
extent of the fair value decline, the financial condition and near-term prospects of the issuer and whether we have the 
intent to sell or will more likely than not be required to sell before the securities' anticipated recovery, which may be at 
maturity. If management determines that a security is impaired under these circumstances, the impairment recognized 
in earnings is measured as the entire difference between the amortized cost and the then-current fair value.

Fair Value of Financial Instruments

Fair value is an exit price, representing the amount that would be received to sell an asset or paid to transfer a liability 
in an orderly transaction between market participants at the measurement date. As such, fair value is a market-based 
measurement that should be determined based on assumptions that market participants would use in pricing an asset 
or a liability.

Our financial assets recorded at fair value on a recurring basis comprise of available for sale marketable securities 
and certificates of deposits. We measure certain financial assets at fair value for disclosure purposes, as well as on a 
nonrecurring basis when they are deemed to be other-than-temporarily impaired. Our other current financial assets 
and our other current financial liabilities, including cash and cash equivalents, restricted cash and cash equivalents, 
WSE related assets and liabilities excluding insurance loss reserves, line of credit and accrued corporate wages, have 
fair values that approximate their carrying value due to their short-term nature.

Assets  and  liabilities  recorded  at  fair  value  are  measured  and  classified  in  accordance  with  a  three-tier  fair  value 
hierarchy based on the observability of the inputs available in the market to measure fair value, summarized as follows:

• 

• 

• 

Level I—observable inputs for identical assets or liabilities, such as quoted prices in active markets,

Level II—inputs other than the quoted prices in active markets that are observable either directly or indirectly,

Level III—unobservable inputs in which there is little or no market data, which requires that we develop our own 
assumptions.

The fair value hierarchy requires us to maximize the use of observable inputs and minimize the use of unobservable 
inputs when measuring fair value. We classify our cash equivalents, debt securities and notes payable in the fair value 
hierarchy based on the lowest level input that is significant to the fair value measurement in its entirety.

62

FINANCIAL STATEMENTS

WSE related Assets and Liabilities 

Current assets and liabilities resulted 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, are reported in WSE related assets and liabilities on the consolidated balance sheets. These assets 
and liabilities are reported separately from our corporate assets and liabilities to better distinguish our corporate position 
from those assets and liabilities held by us to fund client payrolls. 

Unbilled Revenue

We recognize WSE payroll and payroll tax liabilities in the period in which the WSEs perform work. When clients' pay 
periods  cross  reporting  periods,  we  accrue  the  portion  of  the  unpaid  WSE  payroll  where  we  assume,  under  state 
regulations, the obligation for the payment of wages and the corresponding payroll tax liabilities associated with the 
work performed prior to period-end. These estimated payroll and payroll taxes liabilities are accrued wages in WSE 
related liabilities. The associated receivables, including estimated revenues, offset by advance collections from clients, 
are recorded as unbilled revenues in WSE related assets.

Accounts Receivable 

Our accounts receivable recorded in WSE related assets, represent outstanding gross billings to clients, net of an 
allowance for doubtful accounts. We establish an allowance for doubtful accounts based on historical experience, the 
age of the accounts receivable balances, credit quality of clients, current economic conditions and other factors that 
may affect clients’ ability to pay, and charge-off amounts when they are deemed uncollectible. 

Property and Equipment 

We record property and equipment at historical cost and compute depreciation using the straight-line method over the 
estimated useful lives of the assets or the lease terms, generally three to five years for software and office equipment, 
five to seven years for furniture and fixtures, and the shorter of the asset life or the remaining lease term for leasehold 
improvements. We expense the cost of maintenance and repairs as incurred and capitalize leasehold improvements. 

We capitalize internal and external costs incurred to develop internal-use computer software during the application 
development stage. Application development stage costs include license fee paid to third-parties for software use, 
software  configuration,  coding,  and  installation.  Capitalized  costs  are  amortized  on  a  straight-line  basis  over  the 
estimated useful life, typically ranging from three to five years, commencing when the software is placed into service. 
We expense costs incurred during the preliminary project stage, as well as general and administrative, overhead, 
maintenance  and  training  costs,  and  costs  that  do  not  add  functionality  to  existing  systems.  For  the  years  ended 
December 31, 2017, 2016 and 2015, internally developed software costs capitalized were $29 million, $21 million and 
$11 million respectively.

We periodically assess the likelihood of unsuccessful completion of projects in progress, as well as monitor events or 
changes in circumstances, which might suggest that impairment has occurred and recoverability should be evaluated. 
An impairment loss is recognized if the carrying amount of the asset is not recoverable and exceeds the future net 
cash flows expected to be generated by the asset. 

Goodwill and Other Intangible Assets 

Our goodwill and identifiable intangible assets with indefinite useful lives are not amortized, but are tested for impairment 
on an annual basis or when an event occurs or circumstances change in a way to indicate that there has been a 
potential decline in the fair value of the reporting unit. Goodwill impairment is determined by comparing the estimated 
fair value of the reporting unit to its carrying amount, including goodwill. All goodwill is associated with one reporting 
unit within our reportable segment. 

Annually, we perform a qualitative assessment to determine whether it is more likely than not that the fair value of the 
reporting unit has declined below carrying value. This assessment considers various financial, macroeconomic, industry, 
and reporting unit specific qualitative factors. We perform our annual impairment testing in the fourth quarter. Based 
on the results of our reviews, no impairment loss was recognized in the results of operations for the years ended 
December 31, 2017, 2016 and 2015.

63

FINANCIAL STATEMENTS

Intangible assets with finite useful lives are amortized over their respective estimated useful lives ranging from two to 
ten years using either the straight-line method or an accelerated method. Intangible assets are reviewed for indicators 
of impairment at least annually and evaluated for impairment whenever events or changes in circumstances indicate 
that the carrying amount of an asset may not be recoverable. Based on the results of our reviews, no impairment loss 
was recognized in the results of operations for the years ended December 31, 2017, 2016 and 2015.

Impairment of Long-Lived Assets 

We  evaluate  our  long-lived  assets  for  impairment  whenever  events  or  changes  in  circumstances  indicate  that  the 
carrying amount of an asset may not be recoverable. An asset is considered impaired if the carrying amount exceeds 
the undiscounted future net cash flows the asset is expected to generate. An impairment charge is recognized for the 
amount by which the carrying amount of the assets exceeds its fair value. Assets to be disposed of are reported at the 
lower of the carrying amount or fair value, less selling costs. 

Advertising Costs 

We expense the costs of producing advertisements at the time production occurs, and expense the cost of running 
advertisements  in  the  period  in  which  the  advertising  space  or  airtime  is  used  as  sales  and  marketing  expense. 
Advertising costs were $8 million, $6 million, and $8 million for the years ended December 31, 2017, 2016 and 2015, 
respectively. 

Stock-Based Compensation 

We have three types of stock-based awards to employees: restricted stock units (time based and performance based), 
stock options and an employee stock purchase plan. Compensation expense associated with restricted stock units is 
based on the fair value of common stock on the date of grant. Compensation expense associated with stock options 
and employee stock purchase plan are based on the estimated grant date fair value method using the Black-Scholes 
option pricing model. Expense is recognized using a straight-line amortization method over the respective vesting 
period for awards that are ultimately expected to vest, with adjustments to expense recognized in the period in which 
forfeitures occur.

Income Taxes 

We account for our provision for income taxes using the asset and liability method, under which we recognize income 
taxes payable or refundable for current year and deferred tax assets and liabilities for future tax effect of events that 
have been recognized in our financial statements or tax returns. We measure our current and deferred tax assets and 
liabilities based on provision of enacted tax laws of those jurisdictions in which we operate. The effect of changes in 
tax laws and regulations, or interpretations, is recognized in our consolidated financial statements in the period that 
includes the enactment date.

We recognize deferred tax assets and liabilities based on temporary differences between the carrying amounts of 
assets and liabilities for financial reporting purposes and amounts used for income tax purposes, as well as the expected 
benefits of using net operating loss and other carryforwards. We are required to establish a valuation allowance when 
it is determined more likely than not that the deferred tax assets will not be realized. Provision for income taxes may 
change when estimates used in determining valuation allowances change or when receipt of new information indicates 
the need for adjustment in valuation allowances. Changes in valuation allowances are reflected as a component of 
provision for income taxes in the period the change is enacted.

We recognize a reserve for uncertain tax positions taken or expected to be taken in a tax return when it is concluded 
that tax positions are not more likely than not to be sustained upon examination by taxing authorities, including resolution 
of any related appeals or litigation processes, based on the technical merits of the positions. Assumptions, judgment 
and the use of estimates are required in determining if the more likely than not standard has been met when developing 
the provision for income taxes and in determining the expected benefit. The tax benefits of the position recognized in 
the financial statements are then measured based on the largest amount of benefit that is greater than 50% likely to 
be realized upon settlement with a taxing authority. Unrecognized tax benefits due to tax uncertainties that do not meet 
the minimum probability threshold are included as other liabilities and are charged to earnings in the period that such 
determination is made. We recognize interest and penalties related to uncertain tax positions as a component of income 
tax expense. Accrued interest and penalties are included in other liabilities on the consolidated balance sheet. 

64

FINANCIAL STATEMENTS

Concentrations of Credit Risk 

Financial instruments subject to concentrations of credit risk include cash, cash equivalents and investments (including 
payroll funds collected), accounts receivable, and amounts due from insurance carriers. We maintain these financial 
assets principally in domestic financial institutions. We perform periodic evaluations of the relative credit standing of 
these institutions. Our exposure to credit risk in the event of default by the financial institutions holding these funds is 
limited to amounts currently held by the institution in excess of insured amounts. 

Under the terms of professional services agreements, clients agree to maintain sufficient funds or other satisfactory 
credit at all times to cover the cost of their current payroll, all accrued paid time off, vacation or sick leave balances, 
and other vested wage and benefit obligations for all their work site employees. We generally require payment from 
our clients on or before the applicable payroll date. 

For certain clients, we require an indemnity guarantee payment (IGP) supported by a letter of credit, bond, or a certificate 
of deposit from certain financial institutions. The IGP typically equals the total payroll and service fee for one average 
payroll period. 

As of December 31, 2017, one client accounted for 47% of total accounts receivable. No client accounted for more 
than 10% of accounts receivable as of December 31, 2016. No client accounted for more than 10% of total revenues 
in the years ended December 31, 2017, 2016 and 2015. Bad debt expense, net of recoveries was $1 million, $1 million
and $2 million for the years ended December 31, 2017, 2016 and 2015, respectively. 

Recent Accounting Pronouncements

Recently adopted accounting guidance

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

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

We adopted the aspects of the standard affecting the cash flow presentation retrospectively, and accordingly, to conform 
to the current year presentation, we reclassified $5 million and $21 million of tax deficiencies under financing activities 
to operating activities for the years ended December 31, 2016 and 2015, respectively, on our condensed consolidated 
statements of cash flows. The presentation requirements for cash flows related to employee taxes paid for withheld 
shares had no impact to any of the periods presented on our condensed consolidated statements of cash flows since 
such cash flows have historically been presented as a financing activity.

Recent issued accounting pronouncements

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

The  amendment  is  effective  for  annual  reporting  periods,  and  interim  periods  within  those  years  beginning  after 
December 15, 2018. Early adoption is permitted. We plan to adopt beginning January 1, 2019 and are currently in the 
process of evaluating the impact of the adoption of this standard on our consolidated financial statements. It is anticipated 
that  there  will  be  a  material  increase  to  assets  and  lease  liabilities  for  existing  property  leases  representing  our 
nationwide office locations not already included on our consolidated balance sheets.

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

Revenue Recognition - In May 2014, the FASB issued ASU 2014-09-Revenue from Contracts with Customers, which 
will replace most existing revenue recognition guidance under GAAP. The core principle of the guidance is that an 
entity  should  recognize  revenue  for  the  transfer  of  promised  goods  or  services  to  customers  that  reflects  the 
consideration to which the entity expects to be entitled in exchange for those goods or services. The standard provides 
a five-step analysis of transactions to determine when and how revenue is recognized. In July 2015, the FASB deferred 
the effective date to annual reporting periods, and interim periods within those years, beginning after December 15, 
2017. The guidance permits two methods of adoption: retrospectively to each prior reporting period presented (full 
retrospective method), or retrospectively with the cumulative effect of initially applying the guidance recognized at the 
date of initial application (the modified retrospective method). 

We will adopt the new standard effective January 1, 2018 using the modified retrospective method. Under the modified 
retrospective  method,  the  new  standard  will  be  applied  to  all  contracts  initiated  on  or  after  the  effective  date.  For 
contracts with remaining obligations as of the effective date, opening retained earnings will be adjusted for the cumulative 
effect of the change to the new standard as of the effective date.

Impacts on our revenue recognition includes: 

•  Our annual service contracts with our clients that are cancellable with thirty days' notice will be considered 30-

days contracts under the new standard;

•  Professional service revenues will be recognized on a completed contract basis which results in recognition at the 

time payroll is processed;

•  Our  non-refundable  set  up  fees  will  no  longer  be  deferred  but  recognized  as  revenue  when  set  up  service  is 

complete and will be allocated among professional service revenues and insurance revenues;

•  The majority of sales commissions that are currently expensed will be capitalized as contract assets and amortized 

over the estimated customer life.

Statement of Cash Flows - In November 2016, the FASB issued ASU No. 2016-18, Statement of Cash Flows (Topic 
230): Restricted Cash. ASU 2016-18 addresses diversity in practice from entities classifying and presenting transfers 
between cash and restricted cash as operating, investing or financing activities or as a combination of those activities 
in the statement of cash flows. The ASU requires entities to show the changes in the total of cash, cash equivalents, 
restricted cash and restricted cash equivalents in the Statement of Cash Flows. As a result, transfers between such 
categories will no longer be presented in the Statement of Cash Flows. ASU 2016-18 is effective for the Company on 
January 1, 2018 using the retrospective method. As of December 31, 2017 and 2016, we had total restricted cash, 
restricted cash equivalents and payroll funds collected of $1.4 billion and $1.0 billion, respectively. 

In August 2016, the FASB issued ASU No. 2016-15, Statement of Cash Flows (Topic 230): Classification of Certain 
Cash Receipts and Cash Payments). ASU 2016-15 addresses diversity in practice in how certain cash receipts and 
cash payments are presented and classified in the statement of cash flows. This standard addresses the following 
eight  specific  cash  flow  issues:  Debt  prepayment  or  debt  extinguishment  costs;  settlement  of  zero-coupon  debt 
instruments or other debt instruments with coupon interest rates that are insignificant in relation to the effective interest 
rate  of  the  borrowing;  contingent  consideration  payments  made  after  a  business  combination;  proceeds  from  the 
settlement of insurance claims; proceeds from the settlement of corporate-owned life insurance policies; distributions 
received from equity method investees; beneficial interests in securitization transactions; and separately identifiable 
cash flows and application of the predominance principle. ASU 2016-15 is effective for the Company on January 1, 
2018. We are evaluating the effect that this guidance will have on the consolidated financial statements and related 
disclosures and do not expect the impact to be material.

NOTE 2. CASH, CASH EQUIVALENTS AND INVESTMENTS

Under the terms of the agreements with certain of our workers' compensation and health benefit insurance carriers, 
we are required to maintain collateral in trust accounts for the benefit of specified insurance carriers and to reimburse 
the carriers’ claim payments within our deductible layer. We invest a portion of the collateral amounts in marketable 
securities. We report the current portion of these trust accounts as restricted cash and cash equivalents in WSE related 
assets, and long term portion as restricted cash, cash equivalents and investments on the consolidated balance sheets. 

We  require  our  clients  to  prefund  their  payroll  and  related  taxes  and  other  withholding  liabilities  before  payroll  is 
processed or due for payment. This prefund is included in WSE related assets as payroll funds collected which is 
designated to pay pending payrolls and other WSE related liabilities.

There were immaterial realized gains or losses for the years ended December 31, 2017 and 2016. The fair value of 
our U.S. Treasury securities in an unrealized loss position represented 78% and 58% of the total fair value of all U.S. 
Treasury securities as of December 31, 2017 and 2016, respectively.

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

NOTE 3. WORKSITE EMPLOYEE RELATED ASSETS AND LIABILITIES

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

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

•  Payroll funds collected represents cash collected from clients in advance to fund payroll and payroll taxes, and 

other payroll related liabilities; 

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

•  Client deposits, which represents indemnity guarantee payments received from clients and collections from clients 

in excess of payroll and other payroll related liabilities;

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

Incurred claims related to prior years represent changes in estimates for ultimate losses on workers' compensation 
claims. For the year ended December 31, 2017, the favorable development was primarily due to lower than expected 
severity of reported claims associated with office worker WSEs in recent accident years. For the year ended December 
31, 2016, the adverse development was primarily due to higher than expected severity of reported claims associated 
with non-office WSEs in recent accident years. For the year ended December 31, 2015, the adverse development 
resulted from changes in estimates for ultimate losses associated with non-office WSEs.

As of December 31, 2017 and 2016, we had $63 million and $66 million, respectively, of collateral held by insurance 
carriers of which $23 million and $32 million was offset against workers' compensation loss reserves as the agreements 
permit and are net settled of insurance obligations against collateral held.

The Company's restricted cash equivalents include money market mutual funds and commercial paper. The carrying 
value of cash equivalents approximate their fair values due to the short-term maturities and are classified as Level 1 
in  the  fair  value  hierarchy  because  we  use  quoted  market  prices  that  are  readily  available  in  an  active  market  to 
determine the fair value. 

Restricted Investments

The Company's restricted investments include U.S. Treasuries, an exchange traded fund and a certificate of deposit. 
The U.S. Treasuries and exchange traded fund are classified as Level 1 securities in the fair value hierarchy as we 
use active quoted market prices that are readily available in an active market to determine fair value. The certificate 
of deposit is classified as Level 2 in the fair value hierarchy as we use a market approach that compares the fair values 
on certificates with similar maturities.

The  Company  did  not  have  any  Level  3  financial  instruments  as  of  December  31,  2017. There  were  no  transfers 
between levels as of December 31, 2017 and 2016.

In July 2016, we refinanced our Amended and Restated First Lien Credit Agreement (Credit Agreement). We replaced 
$135 million of outstanding tranche B term loans maturing July 2017 with substantially the same amount of new tranche 
A-2 term loans maturing July 2019. The $342 million of existing tranche A term loans and the $75 million revolving 
credit facility were not refinanced. As part of the $135 million refinancing transaction, $58 million was recorded as an 
extinguishment,  and  $77  million  was  rolled  over  into  the  new  tranche A-2  term  loans  and  was  treated  as  a  debt 
modification. 

The proceeds of the tranche A-2 term loans were used to: (i) refinance the remaining tranche B term loans outstanding 
under the Credit Agreement and (ii) pay related fees and expenses. As a result of refinancing our syndicated loan, 
approximately $1 million in fees and costs were incurred, of which a portion was recorded as deferred loan costs for 
continuing lenders with the remainder expensed for those lenders no longer included in the loan syndicate.

Interest on term loans is payable quarterly. We are required to pay a quarterly commitment fee of 0.50% which may 
decrease  to  0.38%  based  on  our  total  leverage  ratio,  on  the  daily  unused  amount  of  the  commitments  under  the 
revolving credit facility, as well as fronting fees and other customary fees for letters of credit issued under the revolving 
credit facility.

We are permitted to make voluntary prepayments at any time without payment of a premium. We are required to make 
mandatory prepayments of term loans (without payment of a premium) with (i) net cash proceeds from issuances of 
debt (other than certain permitted debt), and (ii) net cash proceeds from certain non-ordinary course asset sales and 
casualty and condemnation proceeds (subject to reinvestment rights and other exceptions).

The Credit Agreement contains customary representations and warranties, and customary affirmative and negative 
covenants applicable to us, including, among other things, restrictions on indebtedness, liens, investments, mergers, 
and other dispositions.

Our credit facility is free of net income restrictions. In addition, our credit facility permits us to make customary payments 
that would otherwise be restricted, such as day-to-day intragroup payments or dividends and repurchase of shares 
granted under our equity plans. 

The Credit Agreement restricts our ability to make certain types of payments including dividends and stock repurchases 
and other similar distributions, though such payments may generally be made as long as our total leverage ratio remains 
below 3.00 to 1.00 and there exists no default under the Credit Agreement.

The financial covenants under the Credit Agreement require us to maintain a minimum consolidated interest coverage 
ratio of at least 3.50 to 1.00 at December 31, 2017 and 2016 and a maximum total leverage ratio of 3.75 to 1.00 and 
4.25 to 1.00 at December 31, 2017 and 2016, respectively. We were in compliance with these financial covenants 
under the credit facilities at December 31, 2017 and 2016. 

The credit facility is secured by substantially all of our assets, other than excluded assets as defined in the Credit 
Agreement, which includes certain customary assets, assets held in trusts as collateral and WSE related assets.

The Company has a $75 million revolving credit facility. For additional information regarding these facilities, refer to 
Note 13 in this Form 10-K. 

NOTE 9. STOCKHOLDERS’ EQUITY

Common Stock 

Upon closing of our IPO in March 2014, we issued 15,000,000 shares of common stock at a public offering price $16
per share, for an aggregate offering price of $240 million, resulting in net proceeds to us of $217 million, after deducting 
underwriting  discounts  and  commissions  of  approximately  $17  million  and  offering  expenses  of  approximately  $6 
million.

Equity-Based Incentive Plans

In December 2009, the board of directors approved the 2009 Equity Incentive Plan (the 2009 Plan) which provides for 
the grant of various equity awards to eligible employees, directors, and consultants including stock options, restricted 
stock unit (time-based and performance-based) and other stock awards. Shares available for grant as of December 31, 
2017 were 9 million.

Stock Options

Stock options are granted to employees under the 2009 Plan at exercise prices equal to the fair market value of our 
common stock on the dates of grant. Options generally have a maximum contractual term of 10 years. Options are 
generally vested over four years, based on continued service. Stock options are forfeited if the employee ceases to 
be employed by us prior to vesting.

Restricted Stock Units 

Restricted stock units are subject to time-based or performance-based vesting conditions: 

•  The time-based restricted stock units (RSUs) granted to non-employee directors generally fully vest on the first 

anniversary of the grant date;

•  The RSU granted to employees are generally subject to vesting ratably on a quarterly basis over four years;

  For new hires, one quarter of the total RSUs granted are subject to vesting on the first anniversary of the 

grant date. The remaining RSUs vest ratably on a quarterly basis over three years;

•  The performance-based restricted stock units (PSUs) are subject to vesting based on our achievement of the 
financial performance metrics and other goals that are established at the grant date. Depending on the results 
achieved,  the  actual  number  of  shares  to  be  granted  may  range  from  0%  to  200%  of  the  target  share  value. 
Compensation expense is recognized ratably over the vesting period based on the probability of the number of 
awards expected to vest at each reporting date.

  The financial performance metric established for the PSUs granted during fiscal year 2015, represents 
cumulative annual growth rate in our Net Service Revenues as defined in the grant notice over three-year 
performance periods. 

  The financial performance metric established for the PSUs granted during fiscal year 2017, represents 
annual growth rates in our Net Service Revenues and our Cash from Operations as defined in the grant 
notice. The PSUs will vest 50% in 2018 and the remaining in 2019. 

Unvested restricted stock units are forfeited if the employee ceases to be employed by us prior to vesting.

Employee Stock Purchase Plan

Our 2014 Employee Stock Purchase plan (ESPP) offers eligible employees an option to purchase shares of our common 
stock through a payroll deduction. The purchase price is equal to the lesser of 85% of the fair market value of our 
common stock on the offering date or 85% of the fair market value of our common stock on the applicable purchase 
date. Offering periods are approximately six months in duration and will end on or about May 15 and November 15 of 
each year. Employees may contribute a minimum of 1% and a maximum of 15% of their earnings. The plan is considered 
to be a compensatory plan. We issued 224,928, 283,644, and 272,836 shares under the ESPP during 2017, 2016 and 
2015, respectively. As of December 31, 2017, approximately 2 million shares were reserved for future issuances under 
the ESPP.

Stock-Based Compensation

The fair value of our RSUs and PSUs is equal to the fair value of our common stock on the grant date. The fair value 
of stock options and the ESPP is estimated on the date of grant using the Black-Scholes option-pricing model with the 
following weighted-average assumptions:

NOTE 11. 401(k) PLAN 

Under our 401(k) plan, corporate participants may direct the investment of contributions to their accounts among certain 
investments. We match individual employee 401(k) plan contributions at the rate of $0.50 for every dollar contributed 
by employees subject to a cap. We recorded matching contributions to the 401(k) plan of $6 million, $5 million, and 
$5 million during the years ended December 31, 2017, 2016, and 2015, respectively, which are reflected in various 
operating expense lines within the accompanying consolidated statements of income and comprehensive income. 

We also maintain multiple employer defined contribution plans, which cover WSEs for client companies electing to 
participate in the plan and for their internal staff employees. We contribute, on behalf of each participating client, varying 
amounts based on the clients’ policies and serviced employee elections.

47%

Our  effective  income  tax  rate  decreased  by  30%  from  41%  in  2016  to  11%  in  2017. The  decrease  was  primarily 
attributable to a revaluation of deferred taxes due to federal legislative changes enacted in the fourth quarter ended 
December 31, 2017. The remaining decrease consisted of tax benefits recognized from excess tax benefits related to 
stock-based compensation, qualified production activities deduction for certain software offerings pursuant to Internal 
Revenue Code Section 199 and an increase in tax credits, partially offset by an increase in uncertain tax positions.

The revaluation of deferred taxes resulted in discrete tax (benefit)/expense representing (20)%, (1)% and 5% of the 
effective tax rate for the years ended December 31, 2017, 2016 and 2015, respectively.

We recorded a change of $1 million to the valuation allowance to $7 million in 2017 from $6 million in 2016, related to 
certain state net operating loss and state tax credit carryforwards adjusted in the current year that may not be utilized 
prior to expiration. We have $78 million in multiple state net operating loss carryforwards as of December 31, 2017
and have utilized all of the federal net operating loss carryforwards. The state net operating loss carryforwards will 
begin expiring in 2018. 

Excess tax benefits or deficiencies from share-based award activities are now reflected as a component of the provision 
for income taxes instead of equity. The provision for income taxes for the year ended December 31, 2017 included 
$16 million of excess tax benefits resulting from equity incentive plan activities.

We have $9 million (net of federal benefit) state tax credit carryforwards available that will begin expiring in 2021, which 
are partially offset by a valuation allowance of $6 million and $5 million as of December 31, 2017 and 2016, respectively.

We are subject to tax in U.S. federal and various state and local jurisdictions, as well as Canada. We are not subject 
to any material income tax examinations in federal or state jurisdictions for tax years prior to January 1, 2011. We paid 
Notices of Proposed Assessments disallowing employment tax credits totaling $11 million, plus interest and penalties 
of $4 million in connection with the IRS examination of Gevity HR, Inc. and its subsidiaries, which was acquired by 
TriNet in June 2009. This issue is being resolved through the litigation process. Currently, we anticipate our recovery 
of the refund is likely less than the total amount. 

Pursuant to the Tax Cuts and Jobs Act (TCJA), the approach to the taxation of foreign earnings fundamentally changed 
to require a mandatory deemed repatriation of undistributed foreign earnings and profits at a repatriation toll charge. 
As such a toll charge of less than $1 million will be assessed on our Canadian subsidiary's undistributed earnings of 
$4 million as of December 31, 2017.

Uncertain Tax Positions

As of December 31, 2017 and 2016, the total unrecognized tax benefits related to uncertain income tax positions, 
which would affect the effective tax rate if recognized, were $5 million and $1 million, respectively.

As of December 31, 2017, the total amount of gross interest and penalties accrued was immaterial and $1 million as

liabilities on the consolidated balance sheet. 

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.

NOTE 13. COMMITMENTS AND CONTINGENCIES

Lease Commitments

We lease office facilities, including our headquarters and other facilities under non-cancelable operating leases. The 
schedule of minimum future rental payments under non-cancelable operating leases having initial terms in excess of 
one year at December 31, 2017, is as follows:

The lease agreements generally provide for rental payments on a graduated basis and for options to renew, which 
could increase future minimum lease payments if exercised. We recognize rent expense on a straight-line basis over 
the lease period and accrue for rent expense incurred but not paid. Rent expense for the years ended December 31, 
2017, 2016 and 2015 was $18 million, $17 million and $13 million, respectively. 

Credit Facilities

We maintain a $75 million revolving credit facility which includes capacity for a $40 million letter of credit facility and 
a $10 million swingline facility. Letters of credit issued pursuant to the revolving credit facility reduce the amount available 
for borrowing under the revolving credit facility. The total unused portion of the revolving credit facility was $60 million
as of December 31, 2017.

81

FINANCIAL STATEMENTS

The terms of the credit agreement governing the revolving credit facility require us to maintain certain financial ratios 
at each quarter end. We were in compliance with these covenants as of December 31, 2017.

We also have a $5 million line of credit facility to secure standby letters of credit related to our workers' compensation 
obligation. At December 31, 2017, the total unused portion of the credit facility was $3 million. 

Standby Letters of Credit

We  have  two  standby  letters  of  credit  up  to  an  aggregate  of  $18  million  provided  as  collateral  for  our  workers’ 
compensation obligations. At December 31, 2017, the facilities were not drawn down. 

Contingencies 

In August 2015, Howard Welgus, a purported stockholder filed a putative securities class action lawsuit, Welgus v. 
TriNet Group, Inc. et. al., under the Securities Exchange Act of 1934 in the United States District Court (the Court) for 
the  Northern  District  of  California. The  complaint  was  later  amended  in April  2016  and  again  in  March  2017.  On 
December 19, 2017, the Court granted TriNet’s motion to dismiss the amended complaint in its entirety, without leave 
to amend. Plaintiff filed a notice of appeal of the district court’s order on January 17, 2018. We will defend the appeal 
of the district court’s decision vigorously as we see no basis for reversal. We are unable to reasonably estimate the 
possible loss or expense, or range of losses and expenses, if any, arising from this litigation.

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

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

NOTE 14. RELATED PARTY TRANSACTIONS

We have service agreements with certain stockholders that we process their employees' payrolls and payroll taxes.  
From time to time, we also enter into sales and purchases agreements with various companies that have a relationship 
with our executive officers or members of our board of directors. The relationships are typically an equity investment 
by the executive officer or board member in the customer / vendor company or our executive officer or board member 
is a member of the customer / vendor company's board of directors. We have received $22 million, $10 million, and 
$6 million in total revenues from such related parties during the years ended December 31, 2017, 2016 and 2015, 
respectively.

We  have  also  entered  into  various  software  license  agreements  with  software  service  providers  who  have  board 
members in common with us. We paid the software service providers $6 million, $7 million, and $4 million during the 
years ended December 31, 2017, 2016 and 2015, for services we received, respectively.

DISCLOSURE CONTROLS AND PROCEDURES

Item 9. Changes in and Disagreements with Accountants on Accounting and Financial 
Disclosure. 

None.

Item 9A. 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 December 31, 2017 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 December 31, 2017, our Chief Executive 
Officer and Chief Financial Officer concluded that, as of such date, our disclosure controls and procedures were not 
effective as a result of the material weakness in our internal control over financial reporting, as further described below. 

A material weakness is a deficiency, or a combination of deficiencies, in internal control over financial reporting such 
that there is a reasonable possibility that a material misstatement of our annual or interim financial statements will not 
be prevented or detected on a timely basis.

Notwithstanding the material weakness in our internal control over financial reporting, we have concluded that the 
consolidated financial statements included in this Annual Report on Form 10-K fairly present, in all material respects, 
our financial position, results of operations and cash flows for the periods presented in conformity with accounting 
principles generally accepted in the United States of America. Additionally, the material weakness did not result in any 
restatements of our consolidated financial statements or disclosures for any prior period. 

Management’s Report on Internal Control Over Financial Reporting

We are responsible for establishing and maintaining adequate internal control over financial reporting as defined in 
Rules 13a-15(f) and 15d-15(f) promulgated under the Exchange Act to provide reasonable assurance regarding the 
reliability of financial reporting and the preparation of financial statements for external purposes in accordance with 
GAAP.

Due to inherent limitations, internal control over financial reporting is not intended to provide absolute assurance that 
a misstatement of our financial statements would be prevented or detected. Also, projections of any evaluation of 
effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in 
conditions or that the degree of compliance with policies or procedures may deteriorate.

We, conducted an evaluation of the effectiveness of our internal control over financial reporting as of December 31, 
2017 based on the Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway 
Commission.  Based  on  the  foregoing,  we  concluded  that  our  internal  controls  over  financial  reporting  as  of  
December 31, 2017 were not effective as a result of the material weakness described below.

Deloitte & Touche LLP, our independent registered public accounting firm, has issued an audit report on the effectiveness 
of our internal control over financial reporting as of December 31, 2017. This audit report appears below.

Revenue

We  have  determined  that  we  have  several  control  deficiencies  aggregating  to  a  material  weakness  related  to  the 
operating effectiveness of controls over professional service and workers' compensation insurance services revenues 
as of December 31, 2017. This was primarily caused by control deficiencies related to the lack of complete review and 
available support for our renewal rate price changes.

DISCLOSURE CONTROLS AND PROCEDURES

Changes in Internal Control over Financial Reporting

As of December 31, 2017, our testing of both the design and operating effectiveness of new and re-designed controls 
was completed, and we have concluded that the following material weaknesses existing at December 31, 2016 have 
been remediated:

•  Entity Level Controls - Control Activities and Monitoring 

• 

Information Technology General Controls (ITGC)

•  Payroll Tax Liabilities

• 

Insurance Costs and Insurance Liabilities

•  Payroll Operations and controls over price changes to Health Services revenue

Except for the changes described above there were no changes in our internal control over financial reporting identified 
in  our  evaluation  pursuant  to  Rules  13a-15(d)  or  15d-15(d)  of  the  Exchange Act  during  the  fourth  quarter  ended 
December 31, 2017 that materially affected, or are reasonably likely to materially affect, our internal control over financial 
reporting.

Planned Remediation Activities

We  will  continue  to  further  strengthen  controls  around  the  accuracy  and  completeness  of  invoice  rate  verification 
processes and implement improved documentation processes to evidence our controls. We will continue to consolidate 
platforms in 2018 and retire our legacy SOI platform which will reduce a significant number of manual business process 
controls.

We will continue to test and evaluate the implementation of these new processes and internal controls during 2018 to 
ascertain whether they are designed and operating effectively to provide reasonable assurance that they would prevent 
or detect a material error in our financial statements.

While  we  intend  to  resolve  all  of  the  material  control  deficiencies,  we  cannot  provide  any  assurance  that  these 
remediation efforts will be successful or that our internal control over financial reporting will be effective as a result of 
these efforts by any particular date.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM 

To the shareholders and Board of Directors of TriNet Group, Inc.

Opinion on Internal Control over Financial Reporting

We have audited the internal control over financial reporting of TriNet Group, Inc. and subsidiaries (the "Company”) 
as of December 31, 2017, based on criteria established in Internal Control - Integrated Framework (2013) issued by 
the Committee of Sponsoring Organizations of the Treadway Commission (COSO). In our opinion, because of the 
effect of the material weakness identified below on the achievement of the objectives of the control criteria, the Company 
has  not  maintained  effective  internal  control  over  financial  reporting  as  of  December  31,  2017,  based  on  criteria 
established in Internal Control - Integrated Framework (2013) issued by COSO. 

We have also audited, in accordance with the standards of the Public Company Accounting Oversight Board (United 
States) (PCAOB), the consolidated financial statements and financial statement schedule as of and for the year ended 
December 31, 2017, of the Company and our report dated February 27, 2018 expressed an unqualified opinion on 
those financial statements and financial statement schedule.

Basis for Opinion 

The Company’s management is responsible for maintaining effective internal control over financial reporting and for 
its  assessment  of  the  effectiveness  of  internal  control  over  financial  reporting,  included  in  the  accompanying 
Management's Report on Internal Control Over Financial Reporting. Our responsibility is to express an opinion on the 
Company’s internal control over financial reporting based on our audit. We are a public accounting firm registered with 
the PCAOB and are required to be independent with respect to the Company in accordance with the U.S. federal 
securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.

We conducted our audit in accordance with the standards of the PCAOB. Those standards require that we plan and 
perform the audit to obtain reasonable assurance about whether effective internal control over financial reporting was 
maintained in all material respects. Our audit included obtaining an understanding of internal control over financial 
reporting,  assessing  the  risk  that  a  material  weakness  exists,  testing  and  evaluating  the  design  and  operating 
effectiveness of internal control based on the assessed risk, and performing such other procedures as we considered 
necessary in the circumstances. We believe that our audit provides a reasonable basis for our opinion.

Definition and Limitations of Internal Control over Financial Reporting 

A company's internal control over financial reporting is a process designed to provide reasonable assurance regarding 
the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with 
generally accepted accounting principles. A company's internal control over financial reporting includes those policies 
and procedures that (1) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect 
the transactions and dispositions of the assets of the company; (2) provide reasonable assurance that transactions 
are  recorded  as  necessary  to  permit  preparation  of  financial  statements  in  accordance  with  generally  accepted 
accounting principles, and that receipts and expenditures of the company are being made only in accordance with 
authorizations  of  management  and  directors  of  the  company;  and  (3)  provide  reasonable  assurance  regarding 
prevention or timely detection of unauthorized acquisition, use, or disposition of the company's assets that could have 
a material effect on the financial statements.

Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. 
Also, projections of any evaluation of the effectiveness to future periods are subject to the risk that controls may become 
inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may 
deteriorate.

Material Weakness

A material weakness is a deficiency, or a combination of deficiencies, in internal control over financial reporting, such 
that there is a reasonable possibility that a material misstatement of the company’s annual or interim financial statements 
will not be prevented or detected on a timely basis. The following material weakness has been identified and included 
in management's assessment: 

• 

Ineffective controls over revenue from professional service and workers’ compensation insurance services 
due to the lack of complete review and available support for the Company’s renewal rate price changes

This material weakness was considered in determining the nature, timing, and extent of audit tests applied in our audit 
of the consolidated financial statements and financial statement schedule as of and for the year ended December 31, 
2017, of the Company, and this report does not affect our report on such financial statements.
