To Our Fellow Stakeholders

Building on a quarter of a century of providing vital 
human resource services to our nation’s businesses, 
Administaff has become Insperity, a new brand backed 
by an innovative  strategy for meeting the ongoing 
performance needs of America’s best companies. The 
name Insperity is drawn from the linked entrepreneurial 
goals of inspiration and prosperity, and boldly restates 
our ongoing vision of helping businesses succeed. 

As we prepared to launch our new brand, 2010 saw
Insperity make a strong recovery in both growth and 
profitability, and take advantage of key opportunities 
to strengthen its cash position. In addition, the 
Company announced two acquisitions in the areas 
of expense reporting, time and attendance tracking 
and, in early January 2011, organizational planning, 
furthering our ability to serve more companies 
through complementary business services. We are 
excited about the new Insperity brand and what it 
signifies, energized by a fresh strategy to deliver our 
expanded offering and eager to further support 
America’s entrepreneurial companies.

2010 Financial Performance
Revenues increased 4.0 percent in 2010 to $1.7 billion, on 
a 5.7 percent increase in revenues per worksite employee 
per month and a 1.6 percent decrease in the average num-
ber of paid worksite employees largely due to a reduction 
of worksite employees in early 2010. Gross profit increased 
3.7 percent to $298.5 million, and diluted net income  
per share increased 32.3 percent to $0.86 from $0.65. 

Net income rose from $16.6 million in 2009 to $22.4  
million in 2010, and client satisfaction levels remained  
at an all-time high of 99 percent for the third year in  
a row. 

During 2010, we repurchased $7.9 million of the Com-
pany’s shares, and paid dividends totaling $13.5 million. 
Insperity generated more than $61.1 million in EBITDA 
plus stock-based compensation during the year and 
increased operating income by 37.1 percent to  
$37.1 million. 

These financial results not only affirm a solid return to 
the increasing profitability and growth experienced by 
Insperity, but also help to lay the groundwork for extend-
ing our brand and serving a larger number of businesses, 
employees and their families in 2011 and beyond.

v  Returning to Growth – By the end of 2010, Insperity 
reversed a downward unit growth event from 2009 
caused by the recession and resumed a growth pat-
tern seen in previous economic recoveries, averaging 
111,249 worksite employees in the fourth quarter. 
The reasons for this increase include a retooled sales 
engine, continued high levels of client retention and 
net gains from hiring within our client base. In addi-
tion, the Company built a strong pipeline of qualified 
prospects, improved MidMarket sales and increased 
full-service core market sales. The combination of 
these factors, coupled with the implementation of 
our new adjacent business development strategy, 
sets the stage for continued growth in 2011.

The past year was instrumental for Insperity in proving 
once again the Company’s ability to progress in the
midst of a tepid economy, while addressing the varied 
needs of complementary target markets. The result is 
a company that is financially strong with substantial 
cash reserves and no debt, and is growing its client 
base through strategic market extension and a broad-
ened product mix. Just as 2010 built upon our successful 
business model of the first 25 years, I firmly believe that 
our current transformation will prove to be the driving 
force behind Insperity’s future growth and profitability.  

In closing, I want to thank our corporate staff for 
their hard work and dedication in providing first-class 
business performance improvement services to our 
clients and implementing our exciting new brand. In 
addition, I am sincerely appreciative to our Board of 
Directors for its valuable counsel and guidance 
regarding our 2010 performance and the Company’s 
strategic branding efforts.  Last year, I said that I looked 
forward to a productive 2010, and it certainly was a 
successful year on many levels. I can already see that 
2011 is another milestone period in the Company’s 
timeline of helping businesses succeed so communities 
prosper. Our new brand represents the resourcefulness 
we are using to meet that goal for even more compa-
nies and employees in America, and I look forward to a 
dynamic and profitable year.

Sincerely,

Paul J. Sarvadi
Chairman and Chief Executive Officer
March 31, 2011

v  Resuming Increases in Profitability – In addition  

to resuming our growth momentum, the Company 
has experienced a return to increasing profitability.  
This accomplishment is particularly notable given the 
prolonged sluggish pace of the nation’s economic 
recovery. To help our clients, we implemented 
moderate price decreases for our services during 
the most severe phase of the downturn, but during 
2010, the Company was able to show a slight  
recovery toward our previous rates as clients  
renewed. Additionally, a significant portion of  
Insperity’s profit increases for 2010 were the result 
of effective direct cost management involving 
  workers’ compensation insurance, benefits costs 
(including costs related to COBRA participants) 
and payroll tax costs. If the national economy 
improves in 2011 as some project, any associated 
revenue increases, coupled with continued direct 
cost management efforts, may help position 
the Company for further profit increases.

v  Implementing a New Strategy – Our new name is
backed by a new and exciting growth strategy 
centered on the implementation of our adjacent 
business development plan. The primary goal of  
this effort is to develop profitable adjacent business 
units with recurring revenue streams, strong growth 
potential and substantial cross-selling opportunities 
that feed our core Workforce Optimization business. 
In September, we formally launched eight adjacent 
business offerings following our “Build, Buy, Partner” 
approach. This introduction was the first step  
in expanding the identity of Insperity beyond  
Workforce Optimization and evolving into a  
business performance improvement company  
with the ability to help businesses succeed in a  
variety of ways. The resulting Company changes 
were born out of the desire to grow the primary 
business faster and more consistently, while capital-
izing on the many strengths and assets Insperity has
developed over the last 25 years. We are confident 
that we have the right plan and the right people to 
properly execute this new strategy.

Insperity: A New Brand Backed 
by a Dynamic Strategy

The name Insperity draws meaning from our 25 years 
of support to the business community and simulta- 
neously sets the stage for providing even more services 
to expanded markets over the next quarter of a century. 
Our strategy for achieving this goal is based on four key 
elements that explode our market potential to 
American businesses. 

v  Leveraging our financial strength By tapping the 

Company’s strong cash reserves, Insperity has been 
able to strategically and conservatively make key 
acquisitions and fund important expansion efforts 
that allow us to serve even more businesses. A solid 
balance sheet with little or no debt has long been a 
hallmark of our financial position and equips us to 
serve clients more effectively and efficiently. 

v  Executing our Adjacent Business Development Plan 
For the last few years, the Company has been acquir-
ing complementary client services using a “Build, 
  Buy, Partner” approach. The launch of our Adjacent 
Business Development Plan was the first step in 
expanding the identity of the Company beyond our 
core business, now called Workforce Optimization, 
and evolving into a business performance improve-
ment company with the ability to help businesses 
thrive using a range of services. 

u  We “Build” certain business performance solutions 
from the ground up, such as Insperity Recruiting  
Services and Insperity Retirement Services.

u  At other times, Insperity may “Buy” complementary 
business units, either as existing companies or by 
  acquiring potentially profitable assets, including 

products and processes. We have used this approach 
to purchase USDatalink (Insperity Employment 
Screening), PerformSmart (Insperity Performance 

Management), ExpensAble (Insperity Expense Man-
agement), Galaxy Technologies (Insperity Time and 
Attendance), and OrgPlus (Insperity Organizational 
Planning). The last four business units now or will 
soon provide Software as a Service (SaaS) products 
and services to our clients.

u  Finally, we may “Partner” with firms like we have 
  done with Lockton Affinity Group to offer key 
  business insurance coverage, and with CompuCom 
to provide vital technology support. It is worth 
  noting that these two relationships exemplify how 
  we can meet growing client demands for such ser-
vices and further leverage our resources and small 
and medium-sized business channels.

v  Broadening our product offerings to help all customers 
While the preceding point addresses the method of 
executing our plan, this component speaks more to 
the mix of products and services in that plan. Busi-
nesses often go through progressive stages of devel- 
opment with each having different levels of need. 
Rather than focusing only on those that require the 
complete Workforce Optimization solution, Insperity 
is now or will soon be organized to meet many of the 
essential needs of our nation’s businesses.

v  Expanding our client base Markets are generally  
composed of firms that vary in size, offerings and 
maturity, among other things. There may even be a 
significant degree of category overlap when a company 
is transitioning from one stage to another. Our goal is 
to assist clients in focusing on their core  businesses 
wherever they may be in the growth process. As 
Insperity implements its Adjacent Business Develop-
ment Plan, we will continue to develop our target 
markets and enlarge our client base.

- 4 -

 
 
 
 
 
 
 
 
 
This approach provides Insperity with increased oppor-
tunity to grow our core Workforce Optimization business 
and the overall revenue and earnings of the Company. 
Historically, the lion’s share of our revenue and profit 
comes from the 5,700+ clients and 110,000+ associated 
worksite employees using the complete Workforce 
Optimization solution. Now, through our adjacent busi-
nesses, Insperity supports more than 100,000 small to 
medium-sized companies representing 2 million employees. 

In April 2011, Insperity celebrated its 25th anniversary. 
Over the past quarter of a century, we established a new 
industry and developed the most successful business 
model in our market. The Company built a national sales 
and service infrastructure, replicating processes and pro-
grams that produced consistent growth and profitability.

What started years ago as our primary objective of help-
ing businesses succeed, remains unchanged in principle, 
but dynamic in application. Insperity, both in word and 
deed, is the next step in our journey.

We intend to leverage our 300+ professional Business 
Performance Advisors and Consultants, our substantial 
marketing expertise and the 30,000 Workforce 
Optimization prospects that we see face-to-face each 
year in order to grow the revenues of each of our Adja-
cent Business Units.

Our core Workforce Optimization solution remains the 
best way we can help businesses improve their perfor-
mance. However, Insperity will now be able to offer 
some level of business performance assistance to 
every prospect we call on. Additionally, nine out of 10 
companies not currently qualified for Workforce Opti-
mization are well suited for one or more of our business 
performance solutions, each of which in turn becomes 
an incubator and feeder for our core services.

The financial leverage of this new strategy is substantial. 
Insperity is adding significant ways to grow profitably 
from the major investment it is already making every day 
to get in front of owners of small and medium-sized busi-
nesses. The relatively modest add-on investment to offer 
complementary products and services through our cur-
rent sales organization represents a small percentage of 
the overall costs of our sales infrastructure, but provides 
the Company with vital market expansion opportunities .

Unless otherwise indicated, “Administaff,” “the Company,” “we,” “our” and “us” are used in this annual 
report to refer to the businesses of Administaff, Inc. and its consolidated subsidiaries.  This annual report contains 
forward-looking statements within the meaning of Section 27A of the Securities Act of 1933 and Section 21E of the 
Securities Exchange Act of 1934.  You can identify such forward-looking statements by the words “expects,” 
“intends,” “plans,” “projects,” “believes,” “estimates,” “likely,” “possibly,” “probably,” “goal,” “objective,” 
“assume,” “outlook,” “guidance,” “predicts,” “appears,” “indicator” and similar expressions.  In the normal course 
of business, in an effort to help keep our stockholders and the public informed about our operations we may, from 
time to time, issue such forward-looking statements, either orally or in writing.  Generally, these statements relate to 
business plans or strategies, projected or anticipated benefits or other consequences of such plans or strategies, or 
projections involving anticipated revenues, earnings or other aspects of operating results.  We base the forward-
looking statements on our current expectations, estimates and projections.  We caution you that these statements are 
not guarantees of future performance and involve risks, uncertainties and assumptions that we cannot predict.  In 
addition, we have based many of these forward-looking statements on assumptions about future events that may 
prove to be inaccurate.  Therefore, the actual results of the future events described in such forward-looking 
statements in this annual report, or elsewhere, could differ materially from those stated in such forward-looking 
statements.  Among the factors that could cause actual results to differ materially are the risks and uncertainties 
discussed in this annual report, including, without limitation, factors discussed in Item 1, “Business,” Item 1A, “Risk 
Factors,” and Item 7, “Management’s Discussion and Analysis of Financial Condition and Results of Operations.”  

ITEM 1.   BUSINESS. 

General 

Administaff is a human resource (“HR”) services company.  Our primary HR service is our professional 

employer organization (“PEO”) service, which provides a comprehensive Personnel Management SystemSM 
encompassing a broad range of services, including benefits and payroll administration, health and workers’ 
compensation insurance programs, personnel records management, employer liability management, employee 
recruiting and selection, employee performance management and employee training and development services to 
small and medium-sized businesses in strategically selected markets.  We were organized as a corporation in 1986 
and have provided HR services since inception. 

In addition to our PEO service, we provide business performance improvement services and software 

solutions to assist small to medium-sized businesses.  These services include record keeping for defined contribution 
plans, recruiting and employee screening services, and software solutions for employee expense management, time 
and attendance, performance management, and organizational planning, which we offer via desktop applications and 
software as a service (“SaaS”) delivery models. 

Our principal executive offices are located at 19001 Crescent Springs Drive, Kingwood, Texas 77339.  Our 

telephone number at that address is (281) 358-8986 and our website address is http://www.administaff.com.  Our 
stock is traded on the New York Stock Exchange under the symbol “ASF.”  Periodic Securities and Exchange 
Commission (“SEC”) filings, including our annual reports on Form 10-K, quarterly reports on Form 10-Q, current 
reports on Form 8-K, and if applicable, amendments to those reports filed or furnished pursuant to Section 13(a) or 
15(d) of the Securities Exchange Act of 1934 are available through our website free of charge as soon as reasonably 
practicable after such material is electronically filed with, or furnished to, the SEC. 

Our Personnel Management System, included in our PEO service, is designed to improve the productivity 

and profitability of small and medium-sized businesses.   It relieves business owners and key executives of many 
employer-related administrative and regulatory burdens, which enables them to focus on the core competencies of 
their businesses.  It also promotes employee performance through human resource management techniques designed 
to improve employee satisfaction.  We provide the Personnel Management System by entering into a Client Service 
Agreement (“CSA”), which establishes a three-party relationship whereby we and our client act as co-employers of 
the employees who work at the client’s location (“worksite employees”).  Under the CSA, we assume responsibility 
for personnel administration and compliance with most employment-related governmental regulations, while the 
client retains the employees’ services in its business and remains the employer for various other purposes.  We 
charge a comprehensive service fee (“comprehensive service fee” or “gross billing”), which is invoiced concurrently  

- 2 - 

 
 
 
 
 
 
 
 
 
 
 
with the processing of payroll for the worksite employees of the client.  The comprehensive service fee consists of 
the payroll of our worksite employees and a markup computed as a percentage of the payroll cost of the worksite 
employees. 

We accomplish the objectives of the Personnel Management System through a “High Touch/High Tech” 

approach to service delivery.   In advisory areas, such as recruiting, employee performance management and 
employee training, we employ a high touch approach designed to ensure that our clients receive the personal 
attention and expertise needed to create a customized human resources solution.  For transactional processing, we 
employ a high tech approach that provides secure, convenient information exchange among Administaff, our clients 
and our worksite employees, creating efficiencies for all parties.  The primary component of the high tech portion of 
our strategy is the Employee Service Center (“ESC”).  The ESC is our web-based interactive PEO service delivery 
platform, which is designed to provide automated, personalized PEO services to our clients and worksite employees.  

As of December 31, 2010, we had 51 sales offices in 24 markets.  Our long-term strategy is to operate 

approximately 90 sales offices located in 40 strategically selected markets.   

Our national expansion strategy also includes multiple service centers, which coordinate PEO services for 

clients on a regional basis and localized face-to-face human resource services.  As of December 31, 2010, we had 
four regional service centers, and had human resource and client service personnel located in a majority of our 24 
sales markets, which serviced an average of 111,249 worksite employees per month in the fourth quarter of 2010.   

PEO Industry 

The PEO industry began to evolve in the early 1980s largely in response to the burdens placed on small and 

medium-sized employers by an increasingly complex legal and regulatory environment.  While various service 
providers were available to assist these businesses with specific tasks, PEOs emerged as providers of a more 
comprehensive range of services relating to the employer/employee relationship.  In a PEO arrangement, the PEO 
assumes certain aspects of the employer/employee relationship as defined in the contract between the PEO and its 
client.  Because PEOs provide employer-related services to a large number of employees, they can achieve 
economies of scale that allow them to perform employment-related functions more efficiently, provide a greater 
variety of employee benefits and devote more attention to human resources management than a client can 
individually. 

We believe the key factors driving demand for PEO services include: 

• 

• 
• 

the focus on growth and productivity of the small and medium-sized business community in the United 
States, utilizing outsourcing to concentrate on core competencies;  
the need to provide competitive healthcare and related benefits to attract and retain employees;  
the increasing costs associated with health and workers’ compensation insurance coverage, workplace 
safety programs, employee-related complaints and litigation; and  

•  complex regulation of employment issues and the related costs of compliance, including the allocation of 

time and effort to such functions by owners and key executives. 

A significant factor in the development of the PEO industry has been increasing recognition and acceptance 

of PEOs and the co-employer relationship by federal and state governmental authorities.  Administaff and other 
industry leaders, in concert with the National Association of Professional Employer Organizations (“NAPEO”), 
have worked with the relevant governmental entities for the establishment of a regulatory framework that protects 
clients and employees, discourages unscrupulous and financially unsound companies, and promotes further 
development of the industry.  Currently, 37 states have enacted legislation either recognizing PEOs or requiring 
licensing, registration, or certification, and several others are considering such regulation.  Such laws vary from state 
to state but generally provide for monitoring the fiscal responsibility of PEOs.  State regulation assists in screening 
insufficiently capitalized PEO operations and helps to resolve interpretive issues concerning employee status for 
specific purposes under applicable state law.  We have actively supported such regulatory efforts and are currently 
recognized, licensed, registered, certified or pursuing registration in all 37 of these states.  The cost of compliance 
with these regulations is not material to our financial position or results of operations.

Service Offerings 

PEO Services 

We serve small and medium-sized businesses by providing our Personnel Management System, which 

encompasses a broad range of services, including:  

•  benefits and payroll administration; 
•  health and workers’ compensation insurance programs; 
•  personnel records management; 
•  employer liability management; 
•  employee recruiting and selection; 
•  employee performance management; and 
• 

training and development services. 

The Personnel Management System is designed to attract and retain high-quality employees, while 
relieving client owners and key executives of many employer-related administrative and regulatory burdens.  
Among the employment-related laws and regulations that may affect a client are the following: 

• 
Internal Revenue Code (the “Code”); 
•  Federal Income Contribution Act (FICA); 
•  Federal Unemployment Tax Act (FUTA); 
•  Fair Labor Standards Act (FLSA)*; 
•  Employee Retirement Income Security Act, 

as amended (ERISA); 

•  Consolidated Omnibus Budget Reconcilia- 

• 

tion Act of 1985 (COBRA)*; 
Immigration Reform and Control Act 
(IRCA); 

•  Title VII (Civil Rights Act of 1964)*; 
•  Americans with Disabilities Act (ADA)*; 
•  Age Discrimination in Employment Act 

(ADEA)*; 

•  The Family and Medical Leave Act (FMLA)*; 
•  Health Insurance Portability and 
  Accountability Act (HIPAA); 
•  Drug-Free Workplace Act*; 
•  Occupational Safety and Health Act 

(OSHA)*; 

•  Worker Adjustment and Retraining 
  Notification Act (WARN)*; 
•  Uniformed Services Employment and 
  Reemployment Rights Act (USERRA); 
•  State unemployment and employment 

security laws;  

•  State workers’ compensation laws; and 
•  Health Care and Education Reconciliation 

•  Patient Protection and Affordable Care Act; 

Act of 2010. 

* And similar state laws 

While these regulations are complex, and in some instances overlapping, we assist our clients in achieving 

compliance with these regulations by providing services in four primary categories:  

•  administrative functions;  
•  benefit plans administration; 
•  personnel management; and  
•  employer liability management. 

Mid-market Offering.  We believe the mid-market sector, which we define as those companies with 
employees ranging from 150 to 2,000 worksite employees, has historically been under-served by the PEO industry.  
As a result, we have undertaken an effort over the past four years to refine our sales and marketing strategies, as well 
as our service delivery approach.  Currently we have a dedicated sales management and consulting staff who 
concentrate solely on the mid-market sector.  In addition, we have service personnel who have been trained and 
specialize in the mid-market sector.  The mid-market sector, which represented approximately 15% of our total paid 
worksite employees during 2010, increased 11% over 2009.

All of the following services are included in the Personnel Management System and are available to all 

clients: 

Administrative Functions.  Administrative functions encompass a wide variety of processing and record 
keeping tasks, mostly related to payroll administration and government compliance.  Specific examples include:  

•  payroll processing;  
•  payroll tax deposits;  
•  quarterly payroll tax reporting;  
•  employee file maintenance; 
•  unemployment claims processing; and 
•  workers’ compensation claims reporting. 

Benefit Plans Administration.  We maintain several benefit plans including the following:  

•  a group health plan; 
•  a health care flexible spending account plan; 
•  an educational assistance plan; 
•  an adoption assistance plan; 
•  group term life insurance;  
•  group universal life insurance coverage; 
•  accidental death and dismemberment insurance; 
•  short-term and long-term disability insurance;  
•  a 401(k) retirement plan; and 
•  a cafeteria plan. 

The group health plan includes medical, dental, vision and prescription drug coverage, as well as a worklife 

program. All benefit plans are provided to eligible employees based on the specific eligibility provisions of each 
plan.  We are the policyholder responsible for the costs and premiums associated with any group insurance policies 
that provide benefits under these plans, and we act as plan sponsor and administrator of the plans.  We negotiate the 
terms and costs of the plans, maintain the plans in accordance with applicable federal and state regulations and serve 
as liaison for the delivery of such benefits to worksite employees.  COBRA coverage is extended to eligible 
terminated worksite and corporate employees and other eligible individuals, in accordance with applicable law. We 
believe this variety and quality of benefit plans are generally not available to employees in our small and medium-
sized business target market and are usually offered only by larger companies that can spread program costs over a 
much larger group of employees.  As a result, we believe the availability of these benefit plans provides our clients 
with a competitive advantage that small and medium-sized businesses are typically unable to attain on their own. 

Personnel Management.  We provide a wide variety of personnel management services that give our clients 

access to resources normally found only in the human resources departments of large companies. All clients have 
access to our comprehensive personnel guide, which sets forth a systematic approach to administering personnel 
policies and practices, including recruiting, discipline and termination procedures.  Other human resources services 
we provide include:  

•  drafting and reviewing personnel policies and employee handbooks; 
•  designing job descriptions; 
•  performing prospective employee screening and background investigations; 
•  designing performance appraisal processes and forms; 
•  professional development and issues-oriented training; 
•  employee counseling; 
•  substance abuse awareness training; 
•  drug testing; 
•  outplacement services; and 
•  compensation guidance.

Employer Liability Management.  Under the CSA, we assume many of the employment-related 

responsibilities associated with the administrative functions, benefit plans administration and personnel management 
services we provide.  For many of those employment-related responsibilities that are the responsibility of the client 
or that we share with our clients, we may assist our clients in managing and limiting exposure.  This includes first 
time and ongoing safety-related risk management reviews, as well as the implementation of safety programs 
designed to reduce workplace accidents and consequently, workers’ compensation claims.  We also provide 
guidance to clients for avoiding discrimination, sexual harassment and civil rights violations, and participate in 
termination decisions to attempt to minimize liability on those grounds.  While we do not provide legal services to 
our clients, we employ in-house and external counsel, specializing in several areas of employment law, who have 
broad experience in disputes concerning the employer/employee relationship and who provide support to our human 
resources service specialists.  As part of our comprehensive service, we also maintain employment practice liability 
insurance coverage for ourselves and our clients, monitor changing government regulations and notify clients of the 
potential effect of such changes on employer liability. 

Employee Service CenterSM.  The Employee Service Center (“ESC”) is our web-based interactive PEO 
service delivery platform, which is designed to provide automated, personalized PEO content and services to our 
clients and worksite employees.  The ESC provides a wide range of functionality, including: 

•  WebPayrollSM for the submission and approval of payroll data; 
• 
• 
• 
• 
• 
• 
• 
• 
• 
• 
• 
• 

client-specific payroll information and reports; 
employee information, including online check stubs and pay history reports; 
employee benefits enrollment and changes; 
employee-specific benefits content, including summary plan descriptions and enrollment status; 
access to 401(k) plan information through the Retirement Service CenterSM; 
online human resources forms; 
best practices human resource management process maps and process overviews; 
an online personnel guide; 
e-Learning web-based training; 
online recruiting services; 
links to benefits providers and other key vendors; and 
frequently asked questions. 

MarketPlaceSM.  Through our many alliances with best-of-class providers, Administaff’s MarketPlace is an 

eCommerce portal that brings a wide range of product and services to our clients, worksite employees and their 
families.  MarketPlace also features the Business Network, where our clients can offer their products and services to 
other clients and worksite employees. 

Adjacent Business Unit Offerings 

In 2010, we began to execute an Adjacent Business Unit (“ABU”) growth strategy, which seeks to expand 
the number of business performance improvement services available to our current and prospective client base.  A 
key element of the ABU strategy includes the acquisition of certain human resource technology companies that 
provide services through a SaaS delivery model, as well as record keeping for defined contribution plans, recruiting 
and employee screening services.  Administaff also looks to leverage the existing customer relationships of the 
ABUs to cross sell our PEO services and various ABU services.  During 2010, total ABU revenues unrelated to PEO 
services were less than 1% of our total revenues.  The following are the key components of our ABU services: 

Performance Management Software.  In 2010, we announced the rebranding of our human resource 

software offering, PerformSmart, formerly known as HRTools, and launched Performance Now Online, the newly 
developed SaaS solution for employee performance reviews.  The new product expands and complements our 
existing small business software applications related to job descriptions, performance reviews, and personnel 
policies and procedures.  We plan to integrate these applications into our PEO services in 2011 and will continue to 
sell to small business customers through online subscription arrangements, packaged software ordered online, or 
through various reseller arrangements.   

- 6 - 

 
 
 
 
 
 
 
 
 
Employment Screening Services.  Our employment screening services company, USDatalink, offers a 

customized approach to background-check reporting for companies, including our PEO clients, that outsource this 
portion of their employment-screening process. Services include criminal records checks; verifying employment 
history or education; conducting driving record, civil record and credit history checks; and confirming extraordinary 
credentials. 

Expense Management Software.  Our expense management software division, ExpensAble, delivers 

employee expense management solutions that automate employee expense reporting, enforce travel and expense 
policies, and provide management reporting and analysis.  The software is delivered both as a SaaS solution and as a 
desktop software product.  

Time and Attendance Software.  Our time and attendance software division, Galaxy Technologies, provides 

small to medium-sized businesses, including PEO clients, with software, hardware and services to track, allocate, 
and analyze employee resources and provide inputs into customers’ payroll processing and accounting systems.  The 
software is delivered both as a SaaS solution and as a desktop software product.  

Organizational Planning Software.  In January 2011, we entered the organizational planning and analysis 
software solution business with our acquisition of certain assets from HumanConcepts associated with the OrgPlus 
desktop product lines for small and medium-sized businesses and a source code license for a SaaS based version.  
OrgPlus facilitates the creation, management and communication of detailed organization charts. 

Client Service Agreement 

All PEO clients execute an Administaff CSA.  The CSA generally provides for an on-going relationship 

between Administaff and the PEO client.  The CSA generally is subject to termination by Administaff or the client 
upon 30 days written notice or upon shorter notice in the event of default.  The CSA establishes our comprehensive 
service fee, which is subject to periodic adjustments to account for changes in the composition of the client’s 
workforce, employee benefit election changes and statutory changes that affect our costs.  Under the provisions of 
the CSA, clients active in January of any year are obligated to pay the estimated payroll tax component of the 
comprehensive service fee in a manner that reflects the pattern of incurred payroll tax costs.  This practice aligns 
clients’ payments to Administaff for payroll taxes with Administaff’s obligations to make payments to tax 
authorities, which are higher in the earlier part of the year, and decrease as limits on wages subject to payroll tax, are 
reached.  New clients enrolling subsequent to January of any year are invoiced at a relatively constant rate 
throughout the remaining portion of the year, resulting in Administaff’s improving profitability over the course of 
the year for those clients because of the typical pattern of incurred payroll tax costs.   

The CSA also establishes the division of responsibilities between Administaff and the client as co-
employers.  Pursuant to the CSA, we are responsible for personnel administration and are liable for compliance with 
certain employment-related government regulations.  In addition, we assume liability for payment of salaries and 
wages (as well as related payroll taxes) of our worksite employees and responsibility for providing specified 
employee benefits to such persons.  These liabilities are not contingent on the prepayment by the client of the 
associated comprehensive service fee and, as a result of our employment relationship with each of our worksite 
employees, we are liable for payment of salary and wages to the worksite employees as reported by the client and 
are responsible for providing specified employee benefits to such persons, regardless of whether the client pays the 
associated comprehensive service fee.  The client retains the employees’ services and remains liable for complying 
with certain government regulations, compliance with which requires control of the worksite or daily supervisory 
responsibility or is otherwise beyond our ability to assume.  A third group of responsibilities and liabilities are 
shared by Administaff and the client where such joint responsibility is appropriate.  The specific division of 
applicable responsibilities under the majority of CSAs are as follows: 

Administaff 

•  Payment of wages and salaries as reported by the client and related tax reporting and remittance (local, state and 

federal withholding, FICA, FUTA, state unemployment); 

•  Workers’ compensation compliance, procurement, management and reporting; 

- 7 - 

 
 
 
 
 
 
 
 
 
 
•  Compliance  with  COBRA,  HIPAA  and  ERISA  (for  each  employee  benefit  plan  sponsored  solely  by 
the 

in  other  governmental 

regulations  governing 

Administaff),  as  well  as  monitoring  changes 
employer/employee relationship and updating the client when necessary; and 
•  Employee benefits administration of plans sponsored solely by Administaff. 

Client 

•  Payment, through Administaff, of commissions, bonuses, paid leaves of absence and severance payments; 
•  Payment  and  related  tax  reporting  and  remittance  of  non-qualified  deferred  compensation  and  equity  based 

compensation; 

•  Ownership and protection of all client intellectual property rights; 
•  Compliance  with  OSHA  regulations,  EPA  regulations,  FLSA,  FMLA,  WARN,  USERRA  and  state  and  local 

equivalents and compliance with government contracting provisions; 

•  Compliance  with  the  National  Labor  Relations  Act  (“NLRA”),  including  all  organizing  efforts  and  expenses 

related to a collective bargaining agreement and related benefits; 

•  Professional licensing requirements, fidelity bonding and professional liability insurance;  
•  Products produced and/or services provided; and 
•  COBRA, HIPAA and ERISA compliance for client-sponsored benefit plans. 

Joint 

Implementation of policies and practices relating to the employee/employer relationship; and 

• 
•  Compliance with all federal, state and local employment laws, including, but not limited to Title VII of the Civil 
Rights  Act  of 1964,  ADEA, Title  I  of  ADA,  the  Consumer  Credit  Protection  Act,  and  immigration  laws  and 
regulations. 

We maintain employment practice liability insurance coverages (including coverages for our clients) to 

manage our exposure for various employee-related claims, and as a result, the costs in excess of insurance premiums 
we incur with respect to this exposure have historically been insignificant to our operating results. 

Because we are a co-employer with the client for some purposes, it is possible that we could incur liability 

for violations of such laws, even if we are not responsible for the conduct giving rise to such liability.  The CSA 
addresses this issue by providing that the client will indemnify us for liability incurred to the extent the liability is 
attributable to conduct by the client.  Notwithstanding this contractual right to indemnification, it is possible that we 
could be unable to collect on a claim for indemnification and may therefore be ultimately responsible for satisfying 
the liability in question.  

In most instances, clients are required to remit their comprehensive service fees no later than one day prior 
to the applicable payroll date by wire transfer or automated clearinghouse transaction.  Although we are ultimately 
liable, as the employer for payroll purposes, to pay employees for work previously performed, we retain the ability 
to terminate immediately the CSA and associated worksite employees or to require prepayment, letters of credit or 
other collateral upon deterioration in a client’s financial condition or upon non-payment by a client.  These rights, 
the periodic nature of payroll and the overall quality of our client base have resulted in an excellent overall 
collections history.

PEO Clients 

Administaff’s PEO services provide a value-added, full-service human resources solution we believe is 

most suitable to a specific segment of the small and medium-sized business community.  We target successful 
businesses with 10 to 2,000 employees that recognize the advantage in the strategic use of high-performance human 
resource practices.  We refer to clients with 150 to 2,000 employees as mid-market clients.  These clients, which 
represented approximately 15% of our total client base as of December 2010, are marketed to and serviced by sales 
and service personnel, who specialize in the mid-market sector.  We have set a long-term goal to serve 
approximately 10% of the overall small and medium-sized business community.  We serve clients and worksite 
employees located throughout the United States.  By region, our 2010 revenue change compared to 2009 and 
revenue distribution for the year ended December 31, 2010, was as follows: 

Revenue Change  % of Total Revenues

As part of our client selection strategy, we generally do not offer our PEO services to businesses falling 

within certain specified NAICS (North American Industry Classification System) codes, attempting to minimize our 
exposure to certain industries we believe present a higher employer risk such as employee injury, high turnover or 
litigation.  All prospective PEO clients are evaluated individually on the basis of workers’ compensation risk, group 
medical history (where permitted by law), unemployment history, operating stability and human resource practices.   

Our client base is broadly distributed throughout a wide variety of industries including:

This diverse client base lowers our exposure to downturns or volatility in any particular industry.  

However, our performance could be affected by a downturn in one of these industries or by general economic 
conditions within the small and medium-sized business community.   

We focus heavily on client retention.  During 2010 and 2009, our retention rate was approximately 80% 

and 76%, respectively. Administaff’s client retention record over the last five years reflects that approximately 77% 
of our PEO clients remain for more than one year.  The average annual retention rate over the last five years was 
approximately 79%.  Client attrition is attributable to a variety of factors, including: (i) client non-renewal due to 
price or service factors; (ii) client business failure, sale, merger, or disposition; (iii) our termination of the CSA 
resulting from the client’s non-compliance or inability to make timely payments; and (iv) competition from other 
PEOs or business services firms.

Marketing and Sales 

As of December 31, 2010, we had 51 sales offices located in 24 markets.  Our long-term goal is to operate 

90 sales offices in 40 strategically selected markets.  Our sales offices typically consist of six to eight sales 
representatives, a district sales manager and an office administrator.  To take advantage of economic efficiencies, 
multiple sales offices may share a physical location.  Administaff’s markets and their respective year of entry are as

Our existing and future markets were identified using a systematic market evaluation and selection process. 

We continue to evaluate a broad range of factors in the selection process, using a market selection model that 
weights various criteria we believe are reliable predictors of successful penetration based on our experience. Among 
the factors we consider are:  

•  market size, in terms of small and medium-sized businesses engaged in selected industries that meet 

our risk profile;  

•  market receptivity to PEO services, including the regulatory environment and relevant history with 

• 
• 
• 

• 

• 

other PEO providers;  
existing relationships within a given market, such as vendor or client relationships;  
expansion cost issues, such as advertising and overhead costs;  
direct cost issues that bear on our effectiveness in controlling and managing the cost of our services, 
such as workers’ compensation and health insurance costs, unemployment risks and various legal and 
other factors;  
a comparison of the services we offer to alternatives available to small and medium-sized businesses in 
the relevant market, such as the cost to the target clients of procuring services directly or through other 
PEOs; and  
long-term strategy issues, such as the general perception of markets and our estimate of the long-term 
revenue growth potential of the market.   

- 10 - 

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
Each of our expansion markets, beginning with Dallas in 1993, was selected in this manner.   

Our marketing strategy is based on the application of techniques that have produced consistent and 

predictable results in the past.  We develop a mix of national and local advertising media and a placement strategy 
tailored to each individual market.  After selecting a market and developing our marketing mix, but prior to entering 
the market, we engage in an organized media and public relations campaign to prepare the market for our entry and 
to begin the process of generating sales leads.  We market our services through various business promotions and a 
broad range of media outlets, including television, radio, newspapers, periodicals, direct mail and the Internet.  We 
employ public relations firms for most of our markets as well as advertising consultants to coordinate and implement 
our marketing campaigns.  We have developed an inventory of television, radio and newsprint advertisements, 
which are utilized in this effort.   

We continuously seek to develop new marketing approaches and campaigns to capitalize on changes in the 
competitive landscape for our human resource services and to more successfully reach our target market.  We have 
an agreement with the Professional Golf Association Champions Tour to be the title sponsor of the annual 
Administaff Small Business Classic professional golf tournament held annually in Houston, Texas.  In addition, we 
have arrangements with Arnold Palmer and Jim Nantz, a sports commentator, to serve as our national 
spokespersons.  Our marketing campaigns use this event and the relationships with Mr. Palmer and Mr. Nantz as a 
focal point of our brand marketing efforts. 

Our organic growth model generates sales leads from five primary sources: direct sales efforts, advertising, 
referrals, marketing alliances and the Internet.  These leads result in initial presentations to prospective PEO clients, 
and ultimately, prospective PEO client census reports.  A prospective PEO client’s census report reflects information 
gathered by the sales representative about the prospect’s employees, including job classification, state of 
employment, workers’ compensation claims history, group medical information (where permitted by law), salary 
and desired level of benefits.  This information is entered into our customized bid system, which applies 
Administaff’s proprietary pricing model to the census data, leading to the preparation of a bid.  Concurrent with this 
process, we evaluate the prospective client’s workers’ compensation, health insurance, employer practices and 
financial stability from a risk management perspective.  Upon completion of a favorable risk evaluation, the sales 
representative presents the bid and attempts to enroll the prospect.  Our selling process typically takes approximately 
90 days for clients with less than 150 employees, and up to approximately 180 days for larger clients.  

Competition 

Administaff provides a value-added, full-service human resources solution through its PEO services, which 

we believe is most suitable to a specific segment of the small and medium-sized business community.  This full-
service approach is exemplified by our commitment to provide a high level of service and technology personnel, 
which has produced a ratio of corporate staff to worksite employees (the “staff support ratio”) that is higher than 
average for the PEO industry.  Based on an analysis of the 2007 through 2009 annual NAPEO surveys of the PEO 
industry, we have successfully leveraged our full-service approach into significantly higher returns for Administaff 
on a per worksite employee per month basis.  During the three-year period from 2007 through 2009, our staff 
support ratio averaged 49% higher than the PEO industry average, while gross profit per worksite employee and 
operating income per worksite employee exceeded industry averages by 124% and 140%, respectively. 

Competition in the PEO industry revolves primarily around quality of services, scope of services, choice 

and quality of benefits packages, reputation and price.  We believe reputation, national presence, regulatory 
expertise, financial resources, risk management and information technology capabilities distinguish leading PEOs 
from the rest of the industry.  We also believe we compete favorably in these areas.  

Due to the differing geographic regions and market segments in which most PEOs operate, and the 
relatively low level of market penetration by the industry, we consider our primary competition to be the traditional 
in-house provision of human resource services.  The PEO industry is highly fragmented, and we believe Administaff 
is one of the largest PEO service providers in the United States.  Our largest national competitors include PEO 
divisions of large business services companies such as Automatic Data Processing, Inc. and Paychex, Inc., and other 
PEOs, such as TriNet.  In addition, we compete to some extent with: i) fee-for-service providers such as payroll 
processors and human resource consultants; ii) human resource technology solution companies; and iii) large 

- 11 - 

 
 
 
 
 
 
 
 
 
 
 
regional PEOs in certain areas of the country.  As Administaff and other large PEO service providers expand 
nationally, we expect that competition may intensify. 

Vendor Relationships 

Administaff provides benefits to its worksite employees under arrangements with a variety of vendors. We 

consider our contracts with UnitedHealthcare (“United”) and member insurance companies of ACE American 
Insurance Company (“ACE”) to be the most significant elements of our employee benefits package.  These contracts 
would be the most difficult to replace. 

We provide group health insurance coverage to our worksite employees through a national network of 

carriers including United, Kaiser Permanente, Blue Shield of California, Hawaii Medical Service Association, Unity 
Health Plans and Tufts, all of which provide fully insured policies or service contracts.  The health insurance 
contract with United provides approximately 91% of our health insurance coverage and expires on December 31, 
2013, subject to cancellation by either party upon 180 days notice. For a discussion of our contract with United, 
please read Item 7.  “Management’s Discussion and Analysis of Financial Condition and Results of Operations - 
Critical Accounting Policies and Estimates – Benefits Costs” on page 31. 

Our workers’ compensation coverage (the “ACE Program”) has been provided through an arrangement 
with ACE since 2007.  The ACE Program is a fully insured policy whereby ACE has the responsibility to pay all 
claims incurred under the policy regardless of whether we satisfy our responsibilities. For additional discussion of 
the ACE Program, please read Item 7. “Management’s Discussion and Analysis of Financial Condition and Results 
of Operations - Critical Accounting Policies and Estimates – Workers’ Compensation Costs” on page 32. 

Information Technology 

Administaff utilizes a variety of information technology capabilities to provide its human resource services 

to PEO clients and worksite employees and for its own administrative and management information requirements. 

Administaff Information Management System (“AIMS”) is our proprietary PEO information system and 

utilizes both purchased and internally developed software applications.  This system manages transactions and 
information unique to the PEO industry and to Administaff, including: 

human resource management; 
benefits and defined contribution plan administration; 
payroll processing; 
client invoicing and collection; 

•  worksite employee enrollment;  
• 
• 
• 
• 
•  management information and reporting; and 
• 

sales bid calculations. 

Central to the system are transaction processing capabilities that allow us to process a high volume of 

payroll, invoice, and bid transactions that meet the specific needs of our clients and prospects.  We administer our 
employee benefits through a proprietary application designed to process employee eligibility and enrollments, 
manage carrier relationships, and maintain a variety of plan offerings.  Our retirement services operations are 
conducted utilizing an industry leading retirement plan administration application in a third-party hosted 
environment.  We utilize commercially available software for other business functions such as finance and 
accounting, contract and litigation management, sales force activity management and customer relationship 
management.   

Administaff has hosting facilities located at our corporate headquarters in Kingwood, Texas (a suburb of 
Houston), and in Bryan, Texas.  The hosting facilities house all of our business applications, telecommunications 
equipment and network equipment.  Each hosting facility houses a mix of primary production applications, disaster 
recovery, replication and back-up applications, and pre-production environments.  Both hosting facilities are 
designed to run all of our critical business applications and have sufficient capacity to handle all of our operations on 

- 12 - 

 
 
 
 
 
 
 
 
 
 
 
 
a stand-alone basis, if required.  Periodically, we perform testing to ensure the disaster recovery capabilities remain 
effective and available.  The Company also utilizes additional leased hosting facilities for certain of its sales offices. 

We have a state-of-the-art network infrastructure, which ensures appropriate connectivity exists among all 
of our facilities and employees, and which provides appropriate Internet connectivity to conduct business with our 
clients and worksite employees.  The network infrastructure is provided through industry standard core network 
hardware and via high-speed network services provided by multiple vendors. 

We have incorporated a variety of measures to maintain the security and privacy of the information 
managed through our systems and applications.  These measures include industry standard technologies designed to 
protect, monitor and assess the network environment; best practice security policies and procedures; and standard 
access controls designed to control access to sensitive and private information. 

Industry Regulations 

Administaff’s PEO operations are affected by numerous federal and state laws relating to tax, insurance 
and employment matters.  By entering into a co-employer relationship with our worksite employees, we assume 
certain obligations and responsibilities of an employer under these federal and state laws.  Because many of these 
federal and state laws were enacted prior to the development of nontraditional employment relationships, such as 
PEOs, temporary employment and outsourcing arrangements, many of these laws do not specifically address the 
obligations and responsibilities of nontraditional employers.  Currently, 37 states have passed laws that recognize 
PEOs or require licensing, registration or certification requirements for PEOs, and several others are considering 
such regulation. 

Certain federal and state statutes and regulations use the terms “employee leasing” or “staff leasing” to 
describe the arrangement among a PEO and its clients and worksite employees.  The terms “employee leasing,” 
“staff leasing” and “professional employer arrangements” are generally synonymous in such contexts and describe 
the arrangements we enter into with our PEO clients and worksite employees. 

As an employer, we are subject to federal statutes and regulations governing the employer/employee 

relationship.  Subject to the issues discussed below, we believe that our operations are in compliance, in all material 
respects, with all applicable federal statutes and regulations. 

Employee Benefit Plans 

We offer various employee benefits plans to eligible employees, including our worksite employees.  These 

plans include: 

• 
• 
• 

• 

• 
• 
• 

a 401(k) retirement plan;  
a cafeteria plan under Code Section 125;  
a group health plan, which includes medical, dental, vision and prescription drug coverage, as well as a 
worklife program;  
a welfare benefits plan, which includes life, disability and accidental death and dismemberment 
coverage;  
a health care flexible spending account plan;  
an educational assistance plan; and  
an adoption assistance plan.   

Generally, employee benefit plans are subject to provisions of the Code, ERISA and COBRA. 

Employer Status.  In order to qualify for favorable tax treatment under the Code, employee benefit plans 

must be established and maintained by an employer for the exclusive benefit of its employees.  Generally, an entity 
is an “employer” of individuals for federal employment tax purposes if an employment relationship exists between 
the entity and the individuals under the common law test of employment.  In addition, the officers of a corporation 
are deemed to be employees of that corporation for federal employment tax purposes.  The common law test of 

- 13 - 

 
 
 
 
 
 
 
 
 
 
 
 
 
employment, as applied by the IRS, involves an examination of approximately 20 factors to ascertain whether an 
employment relationship exists between a worker and a purported employer.  Generally, the test is applied to 
determine whether an individual is an independent contractor or an employee for federal employment tax purposes 
and not to determine whether each of two or more companies is a “co-employer.”  Substantial weight is typically 
given to the question of whether the purported employer has the right to direct and control the details of an 
individual’s work.  Among the factors that appear to have been considered more important by the IRS are:  

• 

• 
• 

the employer’s degree of behavioral control (the extent of instructions, training and the nature of the 
work);  
the financial control or the economic aspects of the relationship; and  
the intended relationship of the parties (whether employee benefits are provided, whether any contracts 
exist, whether services are ongoing or for a project, whether there are any penalties for 
discharge/termination, and the frequency of the business activity). 

Patient Protection and Affordable Care Act.  The Patient Protection and Affordable Care Act (“PPACA”) 
was signed into law on March 23, 2010.  The PPACA was subsequently amended on March 30, 2010 by the Health 
Care and Education Reconciliation Act of 2010 (the “Reconciliation Act”).  The PPACA and Reconciliation Act 
(collectively the “Act”) entail sweeping health care reforms with staggered effective dates from 2010 through 2018, 
and many provisions in the Act require the issuance of additional guidance from the U.S. Department of Labor, the 
Internal Revenue Service, the U.S. Department of Health & Human Services, and the states.  Because many 
provisions of the Act do not become operative until future years, the Act did not have a material adverse impact on 
our results of operations in 2010, and we do not expect the Act to have a material adverse impact on our results of 
operations in 2011.  However, given the length and complexity of the Act, the extended time period over which the 
reforms will be implemented, and the unknown impact of yet to be issued regulatory guidance, we are unable to 
determine the impact of the Act on our health insurance plan in future periods.   

The number and complex nature of federal and state regulations facing employers has continued to increase 

over time, including the enactment of the Act.  We believe that additional regulatory burdens placed on employers 
can increase the demand for our services because small and medium-sized businesses are especially challenged by 
such governmental regulations due to limited resources and the lack of expertise.   As a co-employer in the PEO 
relationship, the Company assumes or shares many of the employer-related responsibilities and assists our clients to 
comply with many employment-related governmental regulations.  Historically, the Company believes that it has 
successfully marketed the compliance component of our service offering and that our compliance-related services 
have increased the value proposition of our service offering.   However, currently we are unable to determine the 
impact the Act will have in future periods on the costs we will incur to comply with the Act, our ability to match any 
resulting increased costs with pricing, our ability to attract and retain clients, our business model and our results of 
operations. 

Our review of the Act is ongoing, but we have initially identified certain provisions that could materially 

affect the Company.  Beginning in 2010, the Act provides for a small business tax credit for eligible companies 
offering health care coverage to employees.  Based upon information contained in the Congressional Record, which 
specifically references professional employer organizations, we believe that these tax credits will be available to our 
clients that meet the qualification requirements.  However, the Act and subsequently issued IRS guidance do not 
expressly address the issue of whether qualifying small business clients of a professional employer organization are 
entitled to the tax credits.  At this time, we are unable to determine whether this issue will have an adverse effect on 
our operations or our ability to attract and retain clients.  

Beginning in 2011, the Act contains a number of mandates for health insurance plans, some of which are 
already standard in our group health plan.  For mandates not already included, we have worked with our insurance 
carriers to incorporate the required changes.  One of the 2011 mandates, the requirement to extend dependent child 
coverage to age 26, was implemented in the second quarter of 2010 with respect to certain dependent children 
already covered under our plan.  The Act also provides certain exemptions for “grandfathered plans” in existence on 
March 23, 2010.  Administaff did not claim a grandfathered plan exemption.  While we are unable to determine the 
impact of these required plan changes and grandfathered plan rules at this time, in future periods they may result in 
increased costs to the Company and could affect our ability to attract and retain clients.  Additionally, contractual  

- 14 - 

 
 
 
 
 
 
 
 
 
 
arrangements and competitive market conditions may limit or delay our ability to increase service fees to offset the 
associated potential increased costs.  

Beginning in 2014, the Act provides for the establishment of state insurance exchanges (“Exchanges”) to 
make health insurance available to individuals and small employers (initially defined as 100 or less employees).   
Small business tax credits and subsidies will be available to qualifying businesses and individuals who purchase 
health insurance through the Exchanges.  Also in 2014, the Act implements “pay or play” penalties for large 
employers (those with at least 50 full-time equivalent employees) who fail to offer “minimum essential coverage” or 
affordable coverage to employees.  In 2018, the Act implements rules imposing excise taxes on employers who offer 
excessive health benefits under so-called “Cadillac plans.”  We anticipate taking appropriate steps to avoid, to the 
extent necessary and possible, incurring any such excise taxes.  At this time, we are unable to determine the effect 
the Exchanges, “pay or play” penalties, and excise taxes will have on our costs, our ability to match pricing with any 
increased costs, our results of operations and our ability to attract and retain clients. 

Moreover, multiple lawsuits challenging the constitutionality of the Act are currently pending in the federal 
court system.  There have been conflicting rulings issued in these lawsuits as to whether or not certain provisions of 
the Act are constitutional.  Most recently, on January 31, 2011, a federal court in Florida ruled that the entire Act 
was unconstitutional.  The final resolution of these legal challenges is subject to the appellate process and may 
ultimately require a ruling by the United States Supreme Court. 

ERISA Requirements.  Employee pension and welfare benefit plans are also governed by ERISA.  ERISA 
defines “employer” as “any person acting directly as an employer, or indirectly in the interest of an employer, in 
relation to an employee benefit plan.”  ERISA defines the term “employee” as “any individual employed by an 
employer.”  The United States Supreme Court has held that the common law test of employment must be applied to  
determine whether an individual is an employee or an independent contractor under ERISA.  A definitive judicial 
interpretation of “employer” in the context of a PEO or employee leasing arrangement has not been established. 

If Administaff were found not to be an employer with respect to worksite employees for ERISA purposes, 

its plans would not comply with ERISA.  Further, as a result of such finding Administaff and its plans would not 
enjoy, with respect to worksite employees, the preemption of state laws provided by ERISA and could be subject to 
varying state laws and regulations, as well as to claims based upon state common laws.  Even if such a finding were 
made, we believe we would not be materially adversely affected because we could continue to make available 
similar benefits at comparable costs. 

In addition to ERISA and the Code provisions discussed herein, issues related to the relationship between 
Administaff and its worksite employees may also arise under other federal laws, including other federal income tax 
laws. 

401(k) Retirement Plans.  The Company’s 401(k) Retirement Plans are operated pursuant to guidance 

provided by the Internal Revenue Service under Revenue Procedure 2002-21 and Revenue Procedure 2003-86, each 
of which provides guidance for the operation of defined contribution plans maintained by PEOs that benefit worksite 
employees.  This guidance provides qualification standards for PEO plans which, if met, negate the inquiry of 
common law employer status for purposes of the exclusive benefit rule. 

Employment Taxes 

As a co-employer, Administaff assumes responsibility and liability for the payment of federal and state 
employment taxes with respect to wages and salaries paid to our worksite employees.  There are essentially three 
types of federal employment tax obligations:  

•  withholding of income tax requirements governed by Code Section 3401, et seq.; 
• 
• 

obligations under FICA, governed by Code Section 3101, et seq.; and  
obligations under FUTA, governed by Code Section 3301, et seq.   

Under these Code sections, employers have the obligation to withhold and remit the employer portion and, where 
applicable, the employee portion of these taxes.  

- 15 - 

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
Code Section 3401, which applies to federal income tax withholding requirements, contains an exception to 
the general common law test applied to determine whether an entity is an “employer” for purposes of federal income 
tax withholding.  Section 3401(d)(1) states that if the person for whom services are rendered does not have control 
of the payment of wages, the “employer” for this purpose is the person having control of the payment of wages.  The 
Treasury regulations issued under Section 3401(d)(1) state that a third party can be deemed to be the employer of 
workers under this section for income tax withholding purposes where the person for whom services are rendered 
does not have legal control of the payment of wages.  While Section 3401(d) (1) has been examined by several 
courts, its ultimate scope has not been delineated.  Moreover, the IRS has to date relied extensively on the common 
law test of employment in determining liability for failure to comply with federal income tax withholding 
requirements. 

Accordingly, while we believe that we can assume the withholding obligations for worksite employees, in 
the event we fail to meet these obligations, the client may be held ultimately liable for those obligations.  While this 
interpretive issue has not to our knowledge discouraged clients from enrolling with Administaff, there can be no 
assurance that a definitive adverse resolution of this issue would not do so in the future.  These interpretive 
uncertainties may also impact our ability to report employment taxes on our own account rather than the accounts of 
our clients. 

State Unemployment Taxes 

We record our state unemployment (“SUI”) tax expense based on taxable wages and tax rates assigned by 

each state.  State unemployment tax rates vary by state and are determined, in part, based on Administaff’s prior 
years’ compensation experience in each state.  Certain rates are determined, in part, by each client’s own 
compensation experience.   In addition, states have the ability under law to increase unemployment tax rates to cover 
deficiencies in the unemployment tax funds.  Due to the recent deterioration in U.S. economic activity and the 
associated reductions in employment levels, the state unemployment funds have experienced a significant increase 
in the number of unemployment claims.  Accordingly, state unemployment tax rates increased substantially in 2010 
and 2011.  Rate notices are typically provided by the states during, or prior to, the first quarter of each year; 
however, some notices are received later.  Until we receive the final tax rate notices, we estimate our expected SUI 
rate in those particular states.   

State Regulation 

While many states do not explicitly regulate PEOs, 37 states have adopted provisions for licensing, 
registration, certification or recognition of PEOs, and several others are considering such regulation.  Such laws vary 
from state to state but generally provide for monitoring 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 law.  The Company is in compliance with the requirements in all 37 states.   Regardless of whether a state has 
licensing, registration or certification requirements for PEOs, we must comply with a number of other state and local 
regulations that could impact our operations.  

Corporate Office Employees 

We had approximately 1,900 corporate employees as of December 31, 2010.  We believe our relations with 

our corporate employees are good.  None of our corporate employees is covered by a collective bargaining 
agreement. 

Intellectual Property

ITEM 1A.  RISK FACTORS. 

Factors That May Affect Future Results and the Market Price of Common Stock 

Continued Effects of the Economic Recession may Adversely Affect our Industry, Business and Results 

of Operations 

Over the past several years, the United States economy has experienced negative economic conditions.  
Although conditions have improved over the last year, the future economic environment may continue to be less 
favorable than in years past.  In addition, disruptions in national and international credit markets have lead to a 
scarcity of credit, tighter lending standards and higher interest rates on business loans.  The continued effects of the 
economic recession or a continuing scarcity of credit could adversely affect the financial condition and levels of 
business activity of our clients.  Recent economic conditions have had, and may continue to have, a corresponding 
negative impact on our operating results as some of our clients may suffer business failures, and others may react to 
worsening conditions by reducing their employee headcount, lowering their wage and bonus levels, lowering their 
spending on other human resources benefits and services or determining not to outsource those services to us.  In 
addition, economic conditions may impair our ability to attract new clients.  These circumstances significantly 
impacted our 2009 results.  The decline in U.S. economic activity and associated reductions in employment levels in 
2009 and the latter half of 2008 impacted the Company’s small business customer base and target market.  Our 
average worksite employees per month in 2009 declined 7.0% compared to 2008.  However, during 2010, our 
average number of paid worksite employees increased 8.0% from the first quarter of 2010 to 111,249 in the fourth 
quarter of 2010.  Continued or increased negative economic conditions could have a material adverse effect on our 
future financial results. 

We Assume Liability for Worksite Employee Payroll, Payroll Taxes and Benefits Costs and are 

Responsible for their Payment Regardless of the Amount Billed to or Paid by our Clients 

Under the CSA, we become a co-employer of worksite employees and assume the obligations to pay the 

salaries, wages and related benefits costs and payroll taxes of such worksite employees.  We assume such 
obligations as a principal, not as an agent of the client.  Our obligations include responsibility for:  

• 

payment of the salaries and wages for work performed by worksite employees, regardless of 
whether the client timely pays us the associated service fee; 

•  withholding and payment of federal and state payroll taxes with respect to wages and salaries 

• 

reported by Administaff; and 
providing benefits to worksite employees even if our costs to provide such benefits exceed the fees 
the client pays us.   

If a client does not pay us, or if the costs of benefits we provide to worksite employees exceed the fees a client pays 
us, our ultimate liability for worksite employee payroll and benefits costs could have a material adverse effect on our 
financial condition or results of operations. 

Increases in Health Insurance Premiums or Inability to Secure Replacement Contracts on Competitive 

Terms could have a Material Adverse Effect on our Financial Condition or Results of Operations 

Maintaining health insurance plans that cover worksite employees is a significant part of our business.  Our 

primary health insurance contract expires on December 31, 2013, subject to cancellation by either party upon 180 
days notice.  In the event we are unable to secure replacement contracts on competitive terms, significant disruption 
to our business could occur. 

Health insurance premiums are in part determined by our claims experience and comprise a significant 

portion of our direct costs.  We employ extensive risk management procedures in an attempt to control our claims 
incidence and structure our benefits contracts to provide as much cost stability as possible.  However, if we 
experience a sudden and unexpected large increase in claim activity, our health insurance costs could increase.  
Claim activity levels are impacted by a number of factors, including, but not limited to, macro-economic changes, 
proposed and enacted regulatory changes and medical outbreaks.  Contractual arrangements with our clients limit 
our ability to incorporate such increases into service fees, which could result in a delay before such increases could 
be reflected in service fees.  As a result, such increases could have a material adverse effect on our financial

condition or results of operations.  For additional information related to our health insurance costs, please read Item 
7. “Management’s Discussion and Analysis of Financial Condition and Results of Operations – Critical Accounting 
Policies and Estimates – Benefits Costs,” on page 31. 

Health Care Reform could Affect the Company’s Health Insurance Plan 

The Patient Protection and Affordable Care Act (“PPACA”) was signed into law on March 23, 2010.  The 

PPACA was subsequently amended on March 30, 2010 by the Health Care and Education Reconciliation Act of 
2010 (the “Reconciliation Act”).  The PPACA and Reconciliation Act (collectively the “Act”) entail sweeping 
health care reforms with staggered effective dates from 2010 through 2018, and many provisions in the Act require 
the issuance of additional guidance from the U.S. Department of Labor, the Internal Revenue Service, the U.S. 
Department of Health & Human Services, and the states. 

The number and complex nature of federal and state regulations facing employers has continued to increase 
over time, including the enactment of the Act.  As a co-employer in the PEO relationship, the Company assumes or 
shares many of the employer-related responsibilities and assists our clients to comply with many employment-
related governmental regulations.  However, currently we are unable to determine the impact the Act will have in 
future periods on the costs we will incur to comply with the Act, our ability to match any resulting increased costs 
with pricing, our ability to attract and retain clients, our business model and our results of operations. 

We are currently unable to determine all of the impacts of the required plan changes and provisions 
resulting from the Act. In future periods the changes may result in increased costs to the Company and could affect 
our ability to attract and retain clients.  Additionally, contractual arrangements and competitive market conditions 
may limit or delay our ability to increase service fees to offset any associated potential increased costs.  For 
additional information related to PPACA, please read Item 1. “Business – Industry Regulations – Patient Protection 
and Affordable Care Act,” on page 14.  

Increases in Workers’ Compensation Costs or Inability to Secure Replacement Coverage on Competitive 

Terms could Lead to a Significant Disruption to our Business 

Our workers’ compensation coverage has been provided through an arrangement with ACE since 2007.  

Under our current arrangement with ACE, we bear the economic burden for the first $1 million layer of claims per 
occurrence and the economic burden for claims over $1 million, up to a maximum aggregate amount of $5 million 
per policy year for claims that exceed the first $1 million.  ACE bears the burden for all claims in excess of these 
levels. The ACE Program is a fully insured policy whereby ACE has the responsibility to pay all claims incurred 
under the policy regardless of whether we satisfy our responsibilities. For additional discussion of our policy with 
ACE, please read Item 7. “Management’s Discussion and Analysis of Financial Condition and Results of Operations 
- Critical Accounting Policies and Estimates – Workers’ Compensation Costs” on page 32. 

Workers’ compensation costs are a significant portion of our direct costs.  If we were to experience a 

sudden and unexpected large increase in the number or severity of claims, our workers’ compensation costs could 
increase, which could have a material adverse effect on our results of operations or financial condition.  

The current workers’ compensation coverage with ACE expires on September 30, 2011.  In the event we 

are unable to secure replacement coverage on competitive terms, significant disruption to our business could occur. 

Our  Captive  Insurance  Subsidiary  Tax  Status  could  be  Challenged  Resulting  in  an  Acceleration  of 

Income Tax Payments 

In  conjunction  with  the  formation  of  the  current  workers’  compensation  program  in  2003,  we  formed  a 
wholly owned captive insurance subsidiary (the “Captive”).  We recognize the Captive as an insurance company for 
federal income tax purposes, with respect to our consolidated federal income tax return.  In the event the Internal 
Revenue Service (“IRS”) were to determine that the Captive does not qualify as an insurance company, we could be 
required  to  make  accelerated  income  tax payments  to  the  IRS  that  we  otherwise  would have  deferred until  future 
periods.

Our Ability to Adjust and Collect Service Fees for Increases in Unemployment Tax Rates may be Limited 

We record our state unemployment (“SUI”) tax expense based on taxable wages and tax rates assigned by 

each state.  State unemployment tax rates vary by state and are determined, in part, based on prior years’ 
compensation experience in each state.  Prior to the receipt of final tax rate notices, we estimate our expected SUI 
tax rate in those states for which tax rate notices have not yet been received.  In addition, some states have the ability 
under law to increase unemployment tax rates retroactively to cover deficiencies in the unemployment fund.  Due to 
the recent deterioration in U.S. economic activity and the associated reductions in employment levels, the state 
unemployment funds have experienced a significant increase in the number of unemployment claims.  Accordingly, 
state unemployment tax rates increased substantially in 2010 and 2011.  Generally, our contractual agreements allow 
us to incorporate such increases into our service fees upon the effective date of the rate change.  However, our 
ability to fully adjust service fees in our billing systems and collect such increases over the remaining term of the 
customers’ contracts could be limited, resulting in a potential tax increase not being fully recovered.  As a result, 
such increases could have a material adverse effect on our financial condition or results of operations.  For 
additional information related to state unemployment taxes, please read Note 11 to the financial statements, 
“Commitments and Contingencies,” on page F-27.  

Our Contracts may be Cancelled on Short Notice.  Our Inability to Renew Client Contracts or Attract 

New Clients could Materially and Adversely Affect our Financial Conditions and Results of Operations 

Our standard CSA can generally be cancelled by us or the client with 30 days notice.  Accordingly, the 

short-term nature of the CSA makes us vulnerable to potential cancellations by existing clients, which could 
materially and adversely affect our financial condition and results of operations.  In addition, our results of 
operations are dependent in part upon our ability to retain or replace our clients upon the termination or cancellation 
of the CSA.  Our client attrition rate was approximately 20% in 2010.  There can be no assurance that the number of 
contract cancellations will continue at these levels and such cancellations may increase in the future due to various 
factors, including but not limited to, economic conditions in the markets we operate. 

Established  Competitors  and  New  Market  Entrants  may  have  Greater  Resources  that  Give  Them 

Competitive Advantage over Us 

The human resource services industry, including the PEO industry, is highly fragmented.  Many PEOs have 

limited operations and fewer than 1,000 worksite employees, but there are several industry participants that are 
comparable to our size or larger.  We also encounter competition from “fee for service” companies such as payroll 
processing firms, insurance companies and human resource consultants.  Our competitors include the PEO divisions 
of large business services companies, such as Automatic Data Processing, Inc. and Paychex, Inc.  The PEO divisions 
of such large business services companies with substantially greater resources than Administaff may be able to 
provide their PEO services at more competitive prices than we may be able to offer.  Moreover, we expect that as 
the PEO industry grows and its regulatory framework becomes better established, well-organized competition with 
greater resources than we have may enter the PEO market, possibly including large “fee for service” companies 
currently providing a more limited range of services. 

We may be Subject to Liabilities for Client and Employee Actions 

A number of legal issues remain unresolved with respect to the co-employment arrangement between a 

PEO and its worksite employees, including questions concerning the ultimate liability for violations of employment 
and discrimination laws.  Our CSA establishes the contractual division of responsibilities between Administaff and 
our clients for various personnel management matters, including compliance with and liability under various 
governmental regulations.   

We maintain certain general insurance coverages (including coverages for our clients) to manage certain 
exposure for various employee-related claims, and as a result, the costs in excess of insurance premiums we incur 
with respect to this exposure have historically been insignificant to our operating results. 

Because we act as a co-employer, we may be subject to liability for violations of various employment and 
discrimination laws despite these contractual provisions, even if we do not participate in such violations.  Although 
the CSA provides that the client is to indemnify us for any liability attributable to the client’s conduct, we may not 
be able to collect on such a contractual indemnification claim and thus may be responsible for satisfying such 

- 19 - 

 
 
 
 
 
 
 
 
 
 
 
liabilities to the extent that such liabilities are not covered or insured against under our insurance policies. In 
addition, worksite employees may be deemed to be our agents, which may subject us to liability for the actions of 
such worksite employees.  

Changes  in  Federal,  State  and  Local  Regulation  or  our  Inability  to  Obtain  Licenses  under  New 
Regulatory  Frameworks  could  have  a  Material  Adverse  Effect  on  our  Results  of  Operations  or  Financial 
Condition 

As a major employer, our operations are affected by numerous federal, state and local laws and regulations 
relating to labor, tax, benefit, insurance and employment matters.  By entering into a co-employer relationship with 
employees assigned to work at client locations, we assume certain obligations and responsibilities of an employer 
under these laws.  However, many of these laws (such as ERISA and federal and state employment tax laws) do not 
specifically address the obligations and responsibilities of non-traditional employers such as PEOs, and the 
definition of “employer” under these laws is not uniform.  In addition, many of the states in which we operate have 
not addressed the PEO relationship for purposes of compliance with applicable state laws governing the 
employer/employee relationship.  Any adverse application of new or existing federal or state laws to the PEO 
relationship with our worksite employees and client companies could have a material adverse effect on our results of 
operations or financial condition. 

While many states do not explicitly regulate PEOs, 37 states have passed laws that have recognition, 

licensing, certification or registration requirements for PEOs and several other states are considering such 
regulation.  Such laws vary from state to state, but generally provide for monitoring 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 law.  While we generally support licensing regulation because it serves 
to validate the PEO relationship, we may not be able to satisfy licensing requirements or other applicable regulations 
for all states.  In addition, there can be no assurance that we will be able to renew our licenses in all states. 

Geographic Market Concentration makes our Results of Operations Vulnerable to Economic Factors 

Our Houston, Texas (including Houston), and California markets accounted for approximately 13%, 28% 
and 16%, respectively, of our worksite employees for the year ended December 31, 2010.  Accordingly, while we 
have a goal of expanding in our current markets and into new markets, for the foreseeable future, a significant 
portion of our revenues may be subject to economic factors specific to Texas and California.   

A Determination that a Client is Liable for Employment Taxes not Paid by a PEO may Discourage 

Clients from Contracting with us in the Future 

Under the CSA, we assume sole responsibility and liability for paying federal employment taxes imposed 

under the Code with respect to wages and salaries we pay our worksite employees.  There are essentially three types 
of federal employment tax obligations:  

• 
• 
• 

income tax withholding requirements;  
obligations under the Federal Income Contribution Act (“FICA”); and  
obligations under the Federal Unemployment Tax Act (“FUTA”).   

Under the Code, employers have the obligation to withhold and remit the employer portion and, where 
applicable, the employee portion of these taxes.  Most states impose similar employment tax obligations on the 
employer.  While the CSA provides that we have sole legal responsibility for making these tax contributions, the 
IRS or applicable state taxing authority could conclude that such liability cannot be completely transferred to us.  
Accordingly, in the event that we fail to meet our tax withholding and payment obligations, the client may be held 
jointly and severally liable for those obligations.  While this interpretive issue has not, to our knowledge, 
discouraged clients from enrolling with Administaff, a definitive adverse resolution of this issue may discourage 
clients from enrolling in the future.

Potential Disclosure of Sensitive or Private Information could Damage our Reputation and Impact our 

Operating Results 

Unauthorized access or unintentional disclosure of personal information could damage our reputation and 
operating results.  While we strive to comply with all applicable data protection laws and regulations, and maintain 
stringent privacy and security policies and procedures, any failure or perceived failure to adequately protect 
sensitive information may result in negative publicity and / or proceedings or actions against us by government 
entities or others, which could potentially have an adverse affect on our business.  

Forty-six states and the District of Columbia have enacted notification rules concerning privacy and data 

protection.  It is possible that these laws may be interpreted and applied in a manner that is inconsistent with our 
data practices.  If so, in addition to the possibility of fines, this could result in an order requiring that we change our 
data practices, which could have a material effect on our business.  Complying with these various laws could cause 
us to incur substantial costs or require us to change our business practices in a manner adverse to our business. 

The Failure of our Insurance Carriers could have a Material Adverse Effect on Us 

Administaff contracts with various insurance carriers to provide certain insurance coverages as a part of our 
Personnel Management System, which includes health insurance, workers’ compensation insurance and employment 
practices liability insurance. In addition, Administaff obtains insurance coverage for various commercial risks in our 
business such as property insurance, errors and omissions insurance, general liability insurance, fiduciary liability 
insurance, automobile liability insurance, and directors’ and officers’ liability insurance.  The failure of any 
insurance carrier providing such coverage could leave Administaff exposed to uninsured risk and could have a 
material adverse effect upon Administaff.  

During the third quarter of 2008, it was publicly reported that American International Group, Inc. (“AIG 
Parent”) experienced significant financial difficulties, and the United States Federal Reserve (“Federal Reserve”) 
approved emergency financial assistance to AIG Parent.  AIG Parent received additional financial assistance from 
the Federal Reserve in 2009.  Selected member insurance companies of AIG Parent (the “Selected Member 
Carriers”) provide employment practices liability (“EPL”) insurance to Administaff and our clients, and also remain 
as the carriers for all workers’ compensation claim activity incurred between September 1, 2003 and September 30, 
2007.  As of December 31, 2010, AIG held funds of $23.2 million, which is included in restricted cash and deposits 
on the Company’s Consolidated Balance Sheet, to pay remaining claims under the AIG workers’ compensation 
program.  Although AIG Parent has publicly stated that its Selected Member Carriers remain well-capitalized and 
financially secure, in the event that the Selected Member Carriers fail and are placed into receivership or a similar 
proceeding, the claim funds held by AIG would not necessarily be used to pay the Company’s remaining workers’ 
compensation claims.  Instead, the claims could be paid by guaranty associations that have been established by most 
states, many of which could in turn attempt to return the liability for such claims to Administaff.  Moreover, in the 
event of a failure of the carrier providing the EPL insurance, Administaff may be responsible for the payment of any 
such claims.  Any such events could have a material adverse effect on Administaff’s financial condition and results 
of operations. 

In 2003, facing continued capital constraints and a series of downgrades from various rating agencies, our 

former workers’ compensation insurance carrier for the two-year period ending September 2003, Lumbermens 
Mutual Casualty Company, a unit of Kemper Insurance Companies (“Kemper”), made the decision to substantially 
cease underwriting operations and voluntarily entered into “run-off.”  A “run-off” is the professional management of 
an insurance company’s discontinued distressed or nonrenewed lines of insurance and associated liabilities outside 
of a judicial proceeding.  In the event the run-off process is not successful and Kemper is forced into receivership or 
a similar proceeding, most states have established guaranty funds to pay remaining claims.  However, the guaranty 
associations in some states, including Texas, have asserted that state law returns the liability for open claims under 
such policies to the insured, as we experienced when another former insurance carrier, Reliance Insurance Company 
(“Reliance”), was placed into liquidation in 2001.  In that case, the Texas state guaranty association asserted that it 
was entitled to full reimbursement from us for workers’ compensation benefits paid by the association.  Although 
we settled that dispute within the limits of insurance coverage we had secured to cover potential claims returned to 
us related to the Reliance policies, we have no similar insurance coverage for the Kemper claims.  If one or more 
states were to assert that liability for open claims with Kemper should be returned to us, we may be required to make 

- 21 - 

 
 
 
 
 
 
 
a payment to the state covering estimated claims attributable to us.  Any such payment would reduce net income, 
which may have a material adverse effect on net income in the reported period. 

For additional information about our workers’ compensation insurance, please read “Management’s 
Discussion and Analysis of Financial Condition and Results of Operations ─ Critical Accounting Policies and 
Estimates ─ Workers’ Compensation Costs” on page 32. 

New and Higher State and Municipal Taxes could have a Material and Adverse Impact on our 

Financial Condition and Results of Operations 

Many states and municipalities in which the Company operates have experienced economic slowdowns.  
This decline in economic activity has resulted in reductions of tax revenues and corresponding budget deficits.  In 
response to the budget shortfalls, many states and municipalities have increased or enacted new taxes on businesses 
operating within their tax jurisdiction, including but not limited to, business activity taxes and income taxes.  In 
addition, many states and municipalities have increased their audit activity in an effort to identify additional tax 
revenues.  New tax assessments on the Company’s operations could result in increased costs.  The Company’s 
ability to adjust its service fees and incorporate additional tax assessments into its billing system could be limited.  
As a result, such higher taxes could have a material adverse impact on our financial condition or results of 
operations. 

Failure to Integrate or Realize the Expected Return on Our new Adjacent Business  Strategy, Including 

Acquisitions, could have a Material and Adverse Impact on our Financial Condition and Results of Operations 

We have recently adopted a strategy to market and sell products and services outside of the core PEO 

service.  As a part of this strategy, periodically we make strategic long-term decisions to invest in and/or acquire 
new companies, business units or assets.  New business strategies and the acquisition of new businesses involve risk, 
including those associated with integrating the operations, technologies and personnel.  Failure to effectively 
integrate newly acquired businesses could result in us not achieving anticipated revenues and cost savings.  
Acquiring new businesses could also result in the loss of customers, employees or the diversion of management’s 
attention from other business concerns.  In addition, based on market conditions or changes in operating plans, the 
fair value of our investments could decline, requiring us to record an impairment charge for all or a portion of the 
investment.  The failure to effectively integrate new acquisitions, the diversion of management’s attention from 
other business concerns, or the occurrence of an impairment, could have a material adverse effect on our financial 
condition or operating results. 

ITEM 1B.  UNRESOLVED STAFF COMMENTS. 

None. 

ITEM 2.  PROPERTIES. 

We believe our current facilities are adequate for the purposes for which they are intended and they provide 

sufficient capacity to accommodate our long-term growth and expansion goals.  We believe that short-term leased 
facilities are readily available if needed to accommodate near-term needs if they arise.  We will continue to evaluate 
the need for additional facilities based on the extent of our product and service offerings, the rate of customer 
growth, the geographic distribution of our customer base and our long-term service delivery requirements. 

Corporate Facilities 

Our corporate headquarters is located in Kingwood, Texas, in a 327,000 square foot office campus-style 
facility.  This 28-acre company-owned office campus includes approximately nine acres of undeveloped land for 
future expansion.  All development and support operations are located in the Kingwood facility, along with our 
record retention center and a technology hosting facility.

Service Centers 

We currently have four regional service centers located in Atlanta, Dallas, Houston and Los Angeles. 

The Atlanta service center, which currently services approximately 34% of our worksite employee base, is 

located in a 40,000 square foot facility under lease until 2014. 

The Dallas service center, which currently services approximately 19% of our worksite employee base, is 

located in a 47,500 square foot facility, which is under lease until 2016.   

 The Houston service center, which currently services approximately 23% of our worksite employee base, 

is located in a 60,600 square foot facility under lease until 2014.  In addition to the service center operations, the 
facility also contains corporate support operations.  

The Los Angeles service center, which currently services approximately 24% of our worksite employee 

base, is located in a 45,000 square foot facility under lease until 2012. 

Sales Offices 

As of December 31, 2010, we had PEO sales and service personnel in 36 facilities located in 24 sales 
markets throughout the United States.  All of the facilities are leased facilities, and some of these facilities are shared 
by multiple sales offices and/or client service personnel.  As of December 31, 2010, we had 51 sales offices in these 
24 markets.  To take advantage of economic efficiencies, multiple sales offices may share a physical location.  Each 
sales office is typically staffed by six to eight sales representatives, a district sales manager and an office 
administrator.  In addition, we have placed certain client service personnel in a majority of our sales markets to 
provide high-quality, localized service to our clients in those major markets.  We expect to continue placing various 
client service personnel in sales markets as a critical mass of clients is attained in each market. 

Other Offices 

We maintain seven leased facilities and one Company-owned facility, which are utilized by various 

administrative support personnel as well as ABU operations. 

ITEM 3.  LEGAL PROCEEDINGS. 

We are not a party to any material pending legal proceedings other than ordinary routine litigation 

incidental to our business that we believe would not have a material adverse effect on our financial condition or 
results of operations.   Please read Note 11 to financial statements on page F-27, which is incorporated herein by 
reference. 

ITEM 4.  SUBMISSION OF MATTERS TO A VOTE OF SECURITY HOLDERS.

ITEM  7.      MANAGEMENT’S  DISCUSSION  AND  ANALYSIS  OF  FINANCIAL  CONDITION  AND 
RESULTS OF OPERATIONS. 

You should read the following discussion in conjunction with our Consolidated Financial Statements and 
related Notes included elsewhere in this annual report.  Historical results are not necessarily indicative of trends in 
operating results for any future period. 

The statements contained in this annual report that are not historical facts are forward-looking statements that 
involve a number of risks and uncertainties.  The actual results of the future events described in such forward-looking 
statements in this annual report could differ materially from those stated in such forward-looking statements. Among 
the factors that could cause actual results to differ materially are the risks and uncertainties discussed in Item 1A. Risk 
Factors on page 17 and the uncertainties set forth from time to time in our other public reports and filings and public 
statements. 

Overview 

Our PEO services provide a comprehensive Personnel Management System that encompasses a broad range 

of services, including benefits and payroll administration, health and workers’ compensation insurance programs, 
personnel records management, employer liability management, employee recruiting and selection, employee 
performance management, and employee training and development services.  Our long-term strategy continues to be 
aggregating the best small and medium-sized businesses in the United States on the common platform of our unique 
human resource service offering, thereby leveraging our buying power to provide additional valuable services to 
clients.  Our overall operating results can be measured in terms of revenues, payroll costs, gross profit or operating 
income per worksite employee per month.  We often use the average number of worksite employees paid during a 
period as our unit of measurement in analyzing and discussing our results of operations. 

While the decline in U.S. economic activity and the associated reductions in employment levels significantly 

impacted us in 2009, we implemented strategic plans to minimize the impact of these developments in 2010.  Our 
business plan included, but was not limited to, an increase in our comprehensive service fee in an attempt to recover 
the higher costs associated with higher COBRA enrollment, and reductions in operating expenses through a 5% 
reduction in workforce.   

We ended 2010 averaging 111,249 paid worksite employees in the fourth quarter, which represents an 8.0% 

increase over the first quarter of 2010.  Approximately 15% of our paid worksite employees are in our mid-market 
sector, which is defined as companies with 150 to 2,000 worksite employees.  Our paid mid-market worksite 
employees increased 11% in 2010 over 2009.  We expect the average number of paid worksite employees to increase 
to a range of 112,500 to 113,000 in the first quarter of 2011. 

Our 2010 average gross profit per worksite employee per month was $232, an $11 increase over 2009.  
Higher gross profit per worksite employee per month in 2010 compared to 2009 was primarily the result of a $72 
revenue increase, which was offset by a $61 direct cost increase.  The direct cost increase was due primarily to 
expected increases in medical and payroll tax costs. 

Operating expenses were relatively flat in 2010 at $261.5 million; however, this amount includes 
approximately $5.0 million associated with acquisition costs and operating expenses related to two acquisitions made 
during the year.  On a per worksite employee per month basis, operating expenses increased from $200 in 2009 to 
$204 in 2010. 

Our net income in 2010 was $22.4 million, a $5.9 million increase compared to 2009.  We ended 2010 with 
working capital of $144.5 million.  During 2010, we paid $13.5 million in dividends and repurchased shares at a cost 
of $7.9 million.

Revenues 

We account for our revenues in accordance with Accounting Standards Codification (“ASC”) 605-45, 
Revenue Recognition. Our PEO gross billings to clients include the payroll cost of each worksite employee at the client 
location and a markup computed as a percentage of each worksite employee’s payroll cost.  We invoice the gross 
billings concurrently with each periodic payroll of our worksite employees.  Revenues, which exclude the payroll cost 
component of gross billings, and therefore, consist solely of the markup, are recognized ratably over the payroll period 
as worksite employees perform their service at the client worksite.  This markup includes pricing components 
associated with our estimates of payroll taxes, benefits and workers’ compensation costs, plus a separate component 
related to our HR services.  We include revenues that have been recognized but not invoiced in unbilled accounts 
receivable on our Consolidated Balance Sheets.  

Our revenues are primarily dependent on the number of clients enrolled, the resulting number of worksite 
employees paid each period and the number of worksite employees enrolled in our benefit plans.  Because our total 
markup is computed as a percentage of payroll cost, revenues are also affected by the payroll cost of worksite 
employees, which may fluctuate based on the composition of the worksite employee base, inflationary effects on wage 
levels and differences in the local economies of our markets. 

Direct Costs 

The primary direct costs associated with our PEO revenue-generating activities are:  

employment-related taxes (“payroll taxes”); 
costs of employee benefit plans; and  

• 
• 
•  workers’ compensation costs. 

Payroll taxes consist of the employer’s portion of Social Security and Medicare taxes under FICA, federal 

unemployment taxes and state unemployment taxes.  Payroll taxes are generally paid as a percentage of payroll cost. 
The federal tax rates are defined by federal regulations.  State unemployment tax rates are subject to claim histories 
and vary from state to state. 

Employee benefits costs are comprised primarily of health insurance premiums and claims costs (including 

dental and pharmacy costs), but also include costs of other employee benefits such as life insurance, vision care, 
disability insurance, education assistance, adoption assistance, a flexible spending account and a worklife program. 

Workers’ compensation costs include administrative and risk charges paid to the insurance carrier, and claims 

costs, which are driven primarily by the frequency and severity of claims. 

Gross Profit 

Our gross profit per worksite employee is primarily determined by our ability to accurately estimate and 

control direct costs and our ability to incorporate changes in these costs into the gross billings charged to PEO clients, 
which are subject to contractual arrangements that are typically renewed annually.  We use gross profit per worksite 
employee per month as our principal measurement of relative performance at the gross profit level. 

Operating Expenses 

•  Salaries, wages and payroll taxes – Salaries, wages and payroll taxes are primarily a function of the number of 

corporate employees and their associated average pay and any additional incentive compensation.  Our corporate 
employees include client services, sales and marketing, benefits, legal, finance, information technology and 
administrative support personnel. 

•  Stock-based compensation – Our stock-based compensation primarily relates to the recognition of non-cash 

compensation expense over the vesting period of restricted stock awards. 

- 30 - 

 
  
 
 
 
 
 
 
 
 
 
 
 
 
 
•  General and administrative expenses – Our general and administrative expenses primarily include:  

• 
• 

• 
• 
• 

rent expenses related to our service centers and sales offices;  
outside professional service fees related to legal, consulting and accounting services, and 
acquisition transaction expenses;  
administrative costs, such as postage, printing and supplies;  
employee travel expenses; and 
repairs and maintenance costs. 

•  Commissions – Commission expense consists of amounts paid to sales managers and representatives.  

Commissions are based on the number of new accounts sold and a percentage of revenue generated by such 
personnel. 

•  Advertising – Advertising expense primarily consists of media advertising and other business promotions in our 

current and anticipated sales markets, including the Administaff Small Business Classic sponsorship. 

•  Depreciation and amortization – Depreciation and amortization expense is primarily a function of our capital 

investments in corporate facilities, service centers, sales offices and technology infrastructure. 

Income Taxes 

Administaff’s provision for income taxes typically differs from the U.S. statutory rate of 35%, due primarily 

to state income taxes and non-deductible expenses.  Deferred income taxes reflect the net tax effects of temporary 
differences between the carrying amounts of assets and liabilities used for financial reporting purposes and the 
amounts used for income tax purposes.  Significant items resulting in deferred income taxes include prepaid assets, 
accruals for workers’ compensation expenses, stock-based compensation and depreciation.  Changes in these items are 
reflected in our financial statements through a deferred income tax provision. 

Critical Accounting Policies and Estimates 

Administaff’s discussion and analysis of our financial condition and results of operations are based upon our 

Consolidated Financial Statements, which have been prepared in accordance with accounting principles generally 
accepted in the United States.  The preparation of these financial statements requires our management to make 
estimates and judgments that affect the reported amounts of assets, liabilities, revenues and expenses, and related 
disclosure of contingent assets and liabilities.  On an ongoing basis, we evaluate these estimates, including those 
related to health and workers’ compensation insurance claims experience, client bad debts, income taxes, property and 
equipment, goodwill and other intangibles, and contingent liabilities.  We base these estimates on historical experience 
and on various other assumptions that management believes to be reasonable under the circumstances, the results of 
which form the basis for making judgments about the carrying values of assets and liabilities that are not readily 
apparent from other sources. Actual results may differ from these estimates. 

We believe the following accounting policies are critical and/or require significant judgments and estimates 

used in the preparation of our Consolidated Financial Statements: 

•  Benefits costs – We provide group health insurance coverage to our worksite employees through a national 
network of carriers including UnitedHealthcare (“United”), PacifiCare, Kaiser Permanente, Blue Shield of 
California, Hawaii Medical Service Association, Unity Health Plans and Tufts, all of which provide fully insured 
policies or service contracts.  

The health insurance contract with United provides the majority of our health insurance coverage.  As a result of 
certain contractual terms, we have accounted for this plan since its inception using a partially self-funded 
insurance accounting model.  Accordingly, we record the costs of the United plan, including an estimate of the 
incurred claims, taxes and administrative fees (collectively the “Plan Costs”), as benefits expense in the 
Consolidated Statements of Operations.  The estimated incurred claims are based upon: (i) the level of claims 
processed during the quarter; (ii) estimated completion rates based upon recent claim development patterns under 
the plan; and (iii) the number of participants in the plan, including both active and COBRA enrollees.  

- 31 - 

 
 
 
 
 
 
 
 
 
 
 
 
Each reporting period, changes in the estimated ultimate costs resulting from claim trends, plan design and 
migration, participant demographics and other factors are incorporated into the benefits costs. 

Additionally, since the plan’s inception, under the terms of the contract, United establishes cash funding rates 90 
days in advance of the beginning of a reporting quarter.  If the Plan Costs for a reporting quarter are greater than 
the premiums paid and owed to United, a deficit in the plan would be incurred and we would accrue a liability for 
the excess costs on our Consolidated Balance Sheet.  On the other hand, if the Plan Costs for the reporting quarter 
are less than the premiums paid and owed to United, a surplus in the plan would be incurred and we would record 
an asset for the excess premiums on our Consolidated Balance Sheet.  The terms of the arrangement with United 
require us to maintain an accumulated cash surplus in the plan of $9.0 million, which is reported as long-term 
prepaid insurance.  As of December 31, 2010, Plan Costs were less than the premiums paid and owed to United by 
$28.9 million. As this amount is in excess of the agreed-upon $9.0 million surplus maintenance level, the $19.9 
million balance is included in prepaid insurance, a current asset, on our Consolidated Balance Sheet.  The 
premiums owed to United at December 31, 2010, were $12.1 million, which is included in accrued health 
insurance costs, a current liability, on our Consolidated Balance Sheet. 

We believe the use of recent claims activity is representative of incurred and paid trends during the reporting 
period.  The estimated completion rate used to compute incurred but not reported claims involves a significant 
level of judgment.  Accordingly, an increase (or decrease) in the completion rates used to estimate the incurred 
claims would result in an increase (or decrease) in benefits costs and net income would decrease (or increase) 
accordingly.   

The following table illustrates the sensitivity of changes in the completion rates on our estimate of total 
benefit costs of $759.5 million in 2010:

•  Workers’ compensation costs – Since October 1, 2007, our workers’ compensation coverage has been provided 
through our arrangement with the ACE Group of Companies (“ACE”).  Under our arrangement with ACE (the 
“ACE Program”), we bear the economic burden for the first $1 million layer of claims per occurrence, and 
effective October 1, 2010, we also bear the economic burden for a maximum aggregate amount of $5 million per 
policy year for claim amounts that exceed the first $1 million.  ACE bears the economic burden for all claims in 
excess of these levels.  The ACE Program is a fully insured policy whereby ACE has the responsibility to pay all 
claims incurred under the policy regardless of whether we satisfy our responsibilities.  Our coverage from 
September 1, 2003 through September 30, 2007 was provided through selected member insurance companies of 
American International Group, Inc. (the “AIG Program”).  

Because we bear the economic burden for claims up to the levels noted above, such claims, which are the primary 
component of our workers’ compensation costs, are recorded in the period incurred.  Workers’ compensation 
insurance includes ongoing healthcare and indemnity coverage whereby claims are paid over numerous years 
following the date of injury.  Accordingly, the accrual of related incurred costs in each reporting period includes 
estimates, which take into account the ongoing development of claims and therefore requires a significant level of 
judgment.   

We employ a third party actuary to estimate our loss development rate, which is primarily based upon the nature 
of worksite employees’ job responsibilities, the location of worksite employees, the historical frequency and 
severity of workers’ compensation claims, and an estimate of future cost trends.  Each reporting period, changes 
in the actuarial assumptions resulting from changes in actual claims experience and other trends are incorporated 
into the Company’s workers’ compensation claims cost estimates.  During the years ended December 31, 2010 
and 2009, Administaff reduced accrued workers’ compensation costs by $6.2 million and $5.7 million, 
respectively, for changes in estimated losses related to prior reporting periods.  Workers’ compensation cost 

- 32 - 

 
 
 
 
 
 
 
 
 
 
 
 
 
estimates are discounted to present value at a rate based upon the U.S. Treasury rates that correspond with the 
weighted average estimated claim payout period (the average discount rate utilized in 2010 and 2009 was 1.4% 
and 1.8%, respectively) and are accreted over the estimated claim payment period and included as a component of 
direct costs in our Consolidated Statements of Operations.   

Our claim trends could be greater than or less than our prior estimates, in which case we would revise our claims 
estimates and record an adjustment to workers’ compensation costs in the period such determination is made.  If 
we were to experience any significant changes in actuarial assumptions, our loss development rates could increase 
(or decrease) which would result in an increase (or decrease) in workers’ compensation costs and a resulting 
decrease (or increase) in net income reported in our Consolidated Statement of Operations.   

The following table illustrates the sensitivity of changes in the loss development rate on our estimate of workers’ 
compensation costs totaling $45.6 million in 2010:

At the beginning of each policy period, the insurance carrier establishes monthly funding requirements comprised 
of premium costs and funds to be set aside for payment of future claims (“claim funds”).  The level of claim funds 
is primarily based upon anticipated worksite employee payroll levels and expected workers’ compensation loss 
rates, as determined by the carrier.  Monies funded into the program for incurred claims expected to be paid 
within one year are recorded as restricted cash, a short-term asset, while the remainder of claim funds are included 
in deposits, a long-term asset in our Consolidated Balance Sheets.  In 2010, we received $15.6 million for the 
return of excess claim funds related to the ACE program, which reduced deposits.  As of December 31, 2010, we 
had restricted cash of $41.2 million and deposits of $51.7 million.  We have estimated and accrued $96.9 million 
in incurred workers’ compensation claim costs as of December 31, 2010.  Our estimate of incurred claim costs 
expected to be paid within one year are recorded as accrued workers’ compensation costs and included in short-
term liabilities, while our estimate of incurred claim costs expected to be paid beyond one year are included in 
long-term liabilities on our Consolidated Balance Sheets. 

•  Contingent liabilities – We accrue and disclose contingent liabilities in our Consolidated Financial Statements in 
accordance with ASC 450-10, Contingencies.  U.S. generally accepted accounting principles (“GAAP”) requires 
accrual of contingent liabilities that are considered probable to occur and that can be reasonably estimated.  For 
contingent liabilities that are considered reasonably possible to occur, financial statement disclosure is required, 
including the range of possible loss if it can be reasonably determined. From time to time we disclose in our 
financial statements issues that we believe are reasonably possible to occur, although we cannot determine the 
range of possible loss in all cases.  As issues develop, we evaluate the probability of future loss and the potential 
range of such losses.  If such evaluation were to determine that a loss was probable and the loss could be 
reasonably estimated, we would be required to accrue our estimated loss, which would reduce net income in the 
period that such determination was made.   

•  Deferred taxes – We have recorded a valuation allowance to reduce our deferred tax assets to the amount that is 
more likely than not to be realized.  While we have considered future taxable income and ongoing prudent and 
feasible tax planning strategies in assessing the need for the valuation allowance, our ability to realize our deferred 
tax assets could change from our current estimates.  If we determine that we would be able to realize our deferred 
tax assets in the future in excess of the net recorded amount, an adjustment to reduce the valuation allowance 
would increase net income in the period that such determination is made.  Likewise, should we determine that we 
will not be able to realize all or part of our net deferred tax assets in the future, an adjustment to increase the 
valuation allowance would reduce net income in the period such determination is made.

•  Allowance for doubtful accounts – We maintain an allowance for doubtful accounts for estimated losses resulting 
from the inability of our customers to pay their comprehensive service fees.  We believe that the success of our 
business is heavily dependent on our ability to collect these comprehensive service fees for several reasons, 
including:  

• 

• 
• 

the fact that we are at risk for the payment of our direct costs and worksite employee payroll costs regardless 
of whether our clients pay their comprehensive service fees;  
the large volume and dollar amount of transactions we process; and   
the periodic and recurring nature of payroll, upon which the comprehensive service fees are based.  

To mitigate this risk, we have established very tight credit policies.  We generally require our PEO clients to pay 
their comprehensive service fees no later than one day prior to the applicable payroll date.  In addition, we 
maintain the right to terminate the CSA and associated worksite employees or to require prepayment, letters of 
credit or other collateral if a client’s financial position deteriorates or if the client does not pay the comprehensive 
service fee.  As a result of these efforts, losses related to customer nonpayment have historically been low as a 
percentage of revenues.  However, if our clients’ financial conditions were to deteriorate rapidly, resulting in 
nonpayment, our accounts receivable balances could grow and we could be required to provide for additional 
allowances, which would decrease net income in the period that such determination was made.  

•  Property and equipment – Our property and equipment relate primarily to our facilities and related 

improvements, furniture and fixtures, computer hardware and software and capitalized software development 
costs.  These costs are depreciated or amortized over the estimated useful lives of the assets.  If we determine that 
the useful lives of these assets will be shorter than we currently estimate, our depreciation and amortization 
expense could be accelerated, which would decrease net income in the periods of such a determination.  In 
addition, we periodically evaluate these costs for impairment.  If events or circumstances were to indicate that any 
of our long-lived assets might be impaired, we would assess recoverability based on the estimated undiscounted 
future cash flows to be generated from the applicable asset.  In addition, we may record an impairment loss, which 
would reduce net income, to the extent that the carrying value of the asset exceeded the fair value of the asset.  
Fair value is generally determined using an estimate of discounted future net cash flows from operating activities 
or upon disposal of the asset. 

•  Goodwill and other intangibles – Goodwill is tested for impairment on an annual basis and between annual tests 
in certain circumstances, and written down when impaired. Purchased intangible assets other than goodwill are 
amortized over their useful lives unless these lives are determined to be indefinite.  Our purchased intangible 
assets are carried at cost less accumulated amortization.  Amortization is computed over the estimated useful lives 
of the respective assets, five to ten years. 

New Accounting Pronouncements  

We believe that we have implemented the accounting pronouncements with a material impact on our financial 

statement and do not believe there are any new or pending announcements that will materially impact our financial 
position or results of operations.

Revenues 

Our revenues, which represent gross billings net of worksite employee payroll cost, increased 4.0% compared 

to 2009, due to a 5.7%, or $72 increase in revenues per worksite employee per month, offset in part by a 1.6% 
decrease in the average number of worksite employees paid per month.  The 5.7% increase in revenues per worksite 
employee per month was due primarily to increases in the benefits and payroll tax pricing to offset anticipated 
increases in these direct costs.   

By region, our revenue change from 2009 and revenue distribution for years ended December 31, 2010 and

Our growth in the number of worksite employees paid is affected by three primary sources – new client sales, 

client retention and the net change in existing clients through worksite employee new hires and layoffs.  In 2010, our 
average number of paid worksite employees decreased 1.6% compared to 2009.  However, during 2010 our average 
number of paid worksite employees increased 8.0% from the first quarter of 2010 to 111,249 in the fourth quarter of 
2010, as the net change in existing clients, new client sales and client retention improved throughout 2010. 

Gross Profit  

Gross profit increased 3.7% to $298.5 million compared to 2009.  The average gross profit per worksite 

employee increased 5.0% to $232 per month in 2010 versus $221 in 2009.  Our pricing objectives attempt to maintain 
or improve the gross profit per worksite employee by increasing revenue per worksite employee to match or exceed 
changes in primary direct costs and operating expenses. 

While our revenues per worksite employee per month increased 5.7% to $1,339 on 2010 versus 2009, our 

direct costs, which primarily include payroll taxes, benefits and workers’ compensation expenses, increased 5.8% to 
$1,107 per worksite employee per month.  The primary direct cost components changed as follows: 

•  Benefits costs – The cost of group health insurance and related employee benefits increased $29 per worksite 
employee per month, or 6.0%, on a per covered employee basis compared to 2009.  This increase was due to 
expected medical cost increases, as well as higher claims associated with increased COBRA participation 
resulting from the severe economic environment and the American Recovery and Reinvestment Act of 2009, as 
amended (“ARRA”).  ARRA provided a federal subsidy for COBRA premiums and extended the election period 
for certain terminated employees.  The net costs of claims per COBRA enrollee are approximately double the cost 
of claims associated with active enrollees.  The number of individuals electing COBRA coverage has declined 
from 7.2% in the fourth quarter of 2009 to 5.5% in the fourth quarter of 2010.  The percentage of worksite 
employees covered under our health insurance plan was 74.3% in 2010 versus 74.8% in 2009.  Please read “—
Critical Accounting Policies and Estimates – Benefits Costs” on page 31 for a discussion of our accounting for 
health insurance costs.   

•  Workers’ compensation costs – Workers’ compensation costs decreased 4.1%, but increased $1 per worksite 

employee per month compared to 2009.  As a percentage of non-bonus payroll cost, workers’ compensation costs 
decreased to 0.60% in 2010 from 0.64% in 2009.  During 2010, the Company recorded reductions in workers’ 
compensation costs of $6.2 million, or 0.08% of non-bonus payroll costs, for changes in estimated losses related 
to prior reporting periods, compared to $5.7 million, or 0.08% of non-bonus payroll costs in 2009.  The 2010 
period costs include the impact of a 1.4% discount rate used to accrue workers’ compensation loss claims, 
compared to a 1.8% discount rate used in the 2009 period.  Please read “—Critical Accounting Policies and 
Estimates – Workers’ Compensation Costs” on page 32 for a discussion of our accounting for workers’ 
compensation costs. 

•  Payroll tax costs – Payroll taxes increased 5.3%, or $31 per worksite employee per month compared to 2009.   
Payroll taxes as a percentage of payroll cost increased from 6.96% in 2009 to 7.11% in 2010.  The increases in 
payroll tax costs were due primarily to higher state unemployment tax rates, which increased approximately 50% 
over the 2009 period as a result of unemployment claims experienced during the economic recession and a 4.7% 
increase in average payroll cost per worksite employee per month.

Operating expenses of $261.5 million were relatively flat compared to 2009.  The 2010 operating expenses 

included $5.0 million related to acquisition costs and ongoing operating expenses associated with the ExpensAble and 
Galaxy Technologies acquisitions.  Operating expenses per worksite employee per month increased to $204 in 2010 
versus $200 in 2009.  The components of operating expenses changed as follows: 

•  Salaries, wages and payroll taxes of corporate and sales staff increased 2.0%, or $5 per worksite employee per 

month compared to 2009, primarily due to an increase in our incentive compensation accrual associated with 
our improved operating results compared to 2009.   

•  Stock-based compensation decreased 19.3%, or $2 per worksite employee per month compared to 2009, due 
primarily to a large number of forfeitures in 2010 as a result of employee terminations.  The stock-based 
compensation expense represents amortization of restricted stock awards granted to employees and the annual 
stock grant made to non-employee directors.  Please read Note 1 to the Consolidated Financial Statements on page 
F-17 for additional information.  

•  General and administrative expenses increased 1.3%, or $1 per worksite employee per month. 

•  Commissions expense increased 0.7%, but remained flat on a per worksite employee per month basis compared to 

2009. 

•  Advertising costs increased 2.7%, or $1 per worksite employee per month compared to 2009. 

•  Depreciation and amortization expense decreased 10.2%, or $1 per worksite employee per month compared to the 

2009 period, due primarily to the reduction in capital expenditures during 2009 and 2010.   

Other Income 

Other income decreased to $961,000 in 2010 compared to $1.6 million in 2009, due to the continued decline 

in interest rates. 

Income Tax Expense 

During 2010 we incurred federal and state income tax expense of $15.6 million on pre-tax income of $38.0 

million.  Our provision for income taxes differed from the US statutory rate of 35% primarily due to state income taxes 
and non-deductible expenses, offset slightly by tax-exempt interest income.  Our effective income tax rate was 41.0% 
in the 2010 period compared to 42.1% in the 2009 period.

Our growth in the number of paid worksite employees is affected by three primary sources – new client sales, client 
retention and the net change in existing clients through worksite employee new hires and layoffs.  During 2009, our 
average number of worksite employees declined by 7.0%, as the net change in existing clients, new client sales and 
client retention declined as compared to 2008. 

Gross Profit  

Gross profit decreased 16.2% to $288.0 million compared to 2008.  The average gross profit per worksite 

employee decreased 9.8% to $221 per month in 2009 versus $245 in 2008.  Our pricing objectives attempt to maintain 
or improve the gross profit per worksite employee by increasing revenue per worksite employee to match or exceed 
changes in primary direct costs and operating expenses. 

While our revenues per worksite employee per month increased 3.1% to $1,267 in 2009 versus 2008, our 

direct costs, which primarily include payroll taxes, benefits and workers’ compensation expenses, increased 6.3% to 
$1,046 per worksite employee per month.  The primary direct cost components changed as follows: 

•  Benefits costs – The cost of group health insurance and related employee benefits increased $53 per worksite 
employee per month, or 8.6% on a per covered employee basis compared to 2008.  This increase was due to 
increased utilization by active participants, as well as higher claims associated with increased COBRA 
participation resulting from the severe economic environment and ARRA.  ARRA provided a federal subsidy for 
COBRA premiums and extended the election period for certain terminated employees.  The net costs of COBRA 
claims per enrollee are approximately double the cost of claims associated with active enrollees.  In addition, the 
number of individuals electing COBRA coverage has increased from 3.8% of participants in the United Plan in 
the second quarter of 2008 to 7.2% in the fourth quarter of 2009.  The percentage of worksite employees covered 
under our health insurance plan was 74.8% in 2009 versus 73.5% in 2008.  Please read “—Critical Accounting 
Policies and Estimates – Benefits Costs” on page 31 for a discussion of our accounting for health insurance costs.   

•  Workers’ compensation costs – Workers’ compensation costs decreased 4.4%, but increased $1 per worksite 

employee per month compared to 2008.  As a percentage of non-bonus payroll cost, workers’ compensation costs 
increased to 0.64% in 2009 from 0.63% in 2008.  During 2009, the Company recorded reductions in workers’ 
compensation costs of $5.7 million, or 0.08% of non-bonus payroll costs, for changes in estimated losses related 
to prior reporting periods, compared to $9.8 million, or 0.13% of non-bonus payroll costs in 2008.  The 2009 
period costs include the impact of a 1.8% discount rate used to accrue workers’ compensation loss claims, 
compared to a 2.6% discount rate used in the 2008 period.  Please read “—Critical Accounting Policies and 
Estimates – Workers’ Compensation Costs” on page 32 for a discussion of our accounting for workers’ 
compensation costs. 

•  Payroll tax costs – Payroll taxes decreased 4.9%, but increased $10 per worksite employee per month compared 
to 2008, due to a 2.0% increase in average payroll cost per worksite employee per month.  Payroll taxes as a 
percentage of payroll cost increased from 6.94% in 2008 to 6.96% in 2009.

Operating expenses decreased 6.4% to $260.9 million in 2009 compared to 2008.  Operating expenses per 

worksite employee per month increased to $200 in 2009 versus $199 in 2008.  The components of operating expenses 
changed as follows: 

•  Salaries, wages and payroll taxes of corporate and sales staff decreased 6.2%, and remained flat on a per 
worksite employee per month basis compared to 2008.  During 2009, we initiated a number of operating 
expense savings measures, including the absence of merit salary increases and reductions in 401(k) match for 
corporate employees.  In addition, incentive compensation expense was lower due to reduced operating 
results in 2009 as compared to 2008. 

•  Stock-based compensation increased $94,000 over 2008.  The stock-based compensation expense represents 

amortization of restricted stock awards granted to employees and the annual stock grant made to non-employee 
directors.  Please read Note 1 to the Consolidated Financial Statements on page F-17 for additional information.  

•  General and administrative expenses decreased 10.0%, or $1 per worksite employee per month, due to various 
cost-saving initiatives implemented in 2009, including reductions in travel, overnight postage, repairs and 
maintenance, training and printing. 

•  Commissions expense decreased 6.8%, but remained flat on a per worksite employee per month basis compared to 

2008. 

•  Advertising costs decreased 9.4%, or $1 per worksite employee per month compared to 2008, due to cost-saving 

efforts in 2009 as well as lower advertising rates. 

•  Depreciation and amortization expense increased 6.6%, or $2 per worksite employee per month compared to the 
2008 period, due primarily to depreciation associated with investments in computer software in the latter half of 
2008.   

Other Income 

Other income decreased to $1.6 million in 2009 compared to $7.0 million in 2008, due to the significant 

decline in interest rates. 

Income Tax Expense 

During 2009 we incurred federal and state income tax expense of $12.1 million on pre-tax income of $28.6 

million.  Our provision for income taxes differed from the US statutory rate of 35% primarily due to state income taxes 
and non-deductible expenses, offset slightly by tax-exempt interest income.  Our effective income tax rate was  
42.1% in the 2009 period compared to 36.4% in the 2008 period, due to increases in state income taxes and non-
deductible items, and a decline in tax-exempt interest income.

Net Income 

Net income for 2009 was $16.6 million, or $0.65 per diluted share, compared to $45.8 million, or $1.76 per 
diluted share in 2008.  On a per worksite employee per month basis, net income was $13 in 2009 compared to $33 in 
2008. 

Non-GAAP Financial Measures 

Non-bonus payroll cost is a non-GAAP financial measure that excludes the impact of bonus payrolls paid to our 

worksite employees.  Bonus payroll cost varies from period to period, but has no direct impact to our ultimate workers’ 
compensation costs under the current program.  As a result, our management refers to non-bonus payroll cost in 
analyzing, reporting and forecasting our workers’ compensation costs.  Non-GAAP financial measures are not prepared 
in accordance with GAAP and may be different from non-GAAP financial measures used by other companies.  Non-
GAAP financial measures should not be considered as a substitute for, or superior to, measures of financial performance 
prepared in accordance with GAAP.  We include these non-GAAP financial measures because we believe they are useful 
to investors in allowing for greater transparency related to the costs incurred under our current workers’ compensation 
program.  Investors are encouraged to review the reconciliation of the non-GAAP financial measures used to their most 
directly comparable GAAP financial measures as provided in the table below.

Liquidity and Capital Resources 

We periodically evaluate our liquidity requirements, capital needs and availability of resources in view of, 
among other things, our expansion plans, potential acquisitions, debt service requirements and other operating cash 
needs.  To meet short-term liquidity requirements, which are primarily the payment of direct and operating expenses, 
we rely primarily on cash from operations.  Longer-term projects or significant acquisitions may be financed with debt 
or equity.  We have in the past sought, and may in the future seek, to raise additional capital or take other steps to 
increase or manage our liquidity and capital resources.  We had $278.2  million in cash, cash equivalents and 
marketable securities at December 31, 2010, of which approximately $128.8 million was payable in early January 
2011 for withheld federal and state income taxes, employment taxes and other payroll deductions, and $8.1 million in 
customer prepayments that were payable in January 2011.  At December 31, 2010, we had working capital of $144.5 
million compared to $127.6 million at December 31, 2009.  We currently believe that our cash on hand, marketable 
securities and cash flows from operations will be adequate to meet our liquidity requirements for 2011.  We will rely 
on these same sources, as well as public and private debt or equity financing, to meet our longer-term liquidity and 
capital needs.

Cash Flows from Operating Activities 

Our cash flows from operating activities in 2010 were $78.8 million.  Our primary source of cash from 

operations is the comprehensive service fee and payroll funding we collect from our PEO clients.  The level of cash 
and cash equivalents, and thus our reported cash flows from operating activities are significantly impacted by various 
external and internal factors, which are reflected in part by the changes in our balance sheet accounts.  These include 
the following: 

• 

• 

• 

• 

Timing of client payments / payrolls – We typically collect our comprehensive service fee, along with the 
client’s payroll funding, from clients at least one day prior to the payment of worksite employee payrolls and 
associated payroll taxes.  Therefore, the last business day of a reporting period has a substantial impact on our 
reporting of operating cash flows.  For example, many worksite employees are paid on Fridays and at month-
end; therefore, operating cash flows decrease in the reporting periods that end on a Friday.  In the year ended 
December 31, 2010, which ended on a Friday, client prepayments were $8.1 million and accrued worksite 
employee payroll was $109.7 million. In the year ended December 31, 2009, which ended on a Thursday, 
client prepayments were $13.1 million and accrued worksite employee payroll was $93.1 million. 

Workers’ compensation plan funding – Under our workers’ compensation insurance arrangements, we make 
monthly payments to the carriers comprised of premium costs and funds to be set aside for payment of future 
claims (“claim funds”).  These pre-determined amounts are stipulated in our agreements with the carriers, and 
are based primarily on anticipated worksite employee payroll levels and workers’ compensation loss rates 
during the policy year.  Changes in payroll levels from those that were anticipated in the arrangements can 
result in changes in the amount of the cash payments, which will impact our reporting of operating cash 
flows.  Our claim funds paid, based upon anticipated worksite employee payroll levels and workers’ 
compensation loss rates, were $40.3 million in 2010 and $43.4 million in 2009.  However, our estimates of 
workers’ compensation loss costs were $32.7 million and $33.3 million in 2010 and 2009, respectively.  
During 2010 and 2009, we received $15.6 million and $17.0 million, respectively, for the return of excess 
claim funds related to the workers’ compensation program, which resulted in an increase to working capital.   

Medical plan funding – Our health care contract with United establishes participant cash funding rates 90 
days in advance of the beginning of a reporting quarter.  Therefore, changes in the participation level of the 
United Plan have a direct impact on our operating cash flows.  In addition, changes to the funding rates, 
which are solely determined by United based primarily upon recent claim history and anticipated cost trends, 
also have a significant impact on our operating cash flows.  Since inception of the United plan, premiums 
paid and owed to United have exceeded Plan Costs, resulting in a $28.9 million surplus, $19.9 million of 
which is reflected as a current asset, and $9.0 million of which is reflected as a long-term asset on our 
Consolidated Balance Sheets at December 31, 2010.  The premiums owed to United at December 31, 2010, 
were $12.1 million, which is included in accrued health insurance costs, a current liability, on our 
Consolidated Balance Sheet. 

Operating results – Our net income has a significant impact on our operating cash flows.  Our net income 
increased 35.4% to $22.4 million in 2010 from $16.6 million in 2009.  Please read “Results of Operations – 
Year Ended December 31, 2010 Compared to Year Ended December 31, 2009” on page 35. 

Cash Flows Used in Investing Activities 

Our cash flows used in investing activities were $58.6 million during 2010.  We invested $39.0 million, net, 

in marketable securities, $12.9 million in acquisitions and $6.8 million in capital expenditures. 

Cash Flows Used in Financing Activities 

Our cash flows used in financing activities were $12.5 million during 2010, primarily due to $13.5 million in 

dividends paid.

Seasonality, Inflation and Quarterly Fluctuations 

We believe the effects of inflation have not had a significant impact on our results of operations or financial 

condition. 

ITEM 7A.  QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK. 

We are primarily exposed to market risks from fluctuations in interest rates and the effects of those 
fluctuations on the market values of our cash equivalent short-term investments and our available-for-sale marketable 
securities.  The cash equivalent short-term investments consist primarily of overnight investments, which are not 
significantly exposed to interest rate risk, except to the extent that changes in interest rates will ultimately affect the 
amount of interest income earned on these investments.  The available-for-sale marketable securities are  
subject to interest rate risk because these securities generally include a fixed interest rate.  As a result, the market 
values of these securities are affected by changes in prevailing interest rates. 

We attempt to limit our exposure to interest rate risk primarily through diversification and low investment 

turnover.  Our investment policy is designed to maximize after-tax interest income while preserving our principal 
investment.  As a result, our marketable securities consist of tax-exempt short and intermediate-term debt securities, 
which are primarily prefunded municipal bonds that are secured by escrow funds containing U.S. Government 
Securities.

ITEM 9A.  CONTROLS AND PROCEDURES. 

Evaluation of Disclosure Controls and Procedures 

In accordance with Exchange Act Rules 13a-15 and 15a-15, we carried out an evaluation, under the 

supervision and with the participation of management, including our Chief Executive Officer and Chief Financial 
Officer, of the effectiveness of our disclosure controls and procedures as of the end of the period covered by this 
report.  Based on that evaluation, our Chief Executive Officer and Chief Financial Officer concluded that our 
disclosure controls and procedures were effective as of December 31, 2010. 

Design and Evaluation of Internal Control over Financial Reporting 

Pursuant to Section 404 of the Sarbanes-Oxley Act of 2002, we included a report of management’s 
assessment of the design and effectiveness of our internal controls as part of this Annual Report on Form 10-K for the 
fiscal year ended December 31, 2010.  Ernst & Young, LLP, our independent registered public accounting firm, also 
attested to our internal control over financial reporting.  Management’s report and the independent registered public 
accounting firm’s attestation report are included in our 2010 Consolidated Financial Statements on pages F-3 and F-4 
under the captions entitled “Management’s Report on Internal Control over Financial Reporting” and “Report of 
Independent Registered Public Accounting Firm on Internal Control over Financial Reporting,” and are incorporated 
herein by reference. 

There has been no change in our internal controls over financial reporting that occurred during the three 

months ended December 31, 2010, that has materially affected, or is reasonably likely to materially affect, our internal 
controls over financial reporting.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM 

Board of Directors and Stockholders 
Administaff, Inc. 

We have audited the accompanying Consolidated Balance Sheets of Administaff, Inc. as of December 31, 2010 and 
2009, and the related Consolidated Statements of Operations, Stockholders’ Equity and Cash Flows for each of the 
three years in the period ended December 31, 2010.  These financial statements are the responsibility of the 
Company’s management.  Our responsibility is to express an opinion on these financial statements based on our 
audits. 

We conducted our audits in accordance with the standards of the Public Company Accounting Oversight Board 
(United States).  Those standards require that we plan and perform the audit to obtain reasonable assurance about 
whether the financial statements are free of material misstatement.  An audit includes examining, on a test basis, 
evidence supporting the amounts and disclosures in the financial statements.  An audit also includes assessing the 
accounting principles used and significant estimates made by management, as well as evaluating the overall financial 
statement presentation.  We believe that our audits provide a reasonable basis for our opinion. 

In our opinion, the financial statements referred to above present fairly, in all material respects, the consolidated 
financial position of Administaff, Inc. at December 31, 2010 and 2009, and the consolidated results of its operations 
and its cash flows for each of the three years in the period ended December 31, 2010, in conformity with U.S. 
generally accepted accounting principles. 

We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United 
States), Administaff, Inc.’s internal control over financial reporting as of December 31, 2010, based on criteria 
established in Internal Control – Integrated Framework issued by the Committee of Sponsoring Organizations of the 
Treadway Commission and our report dated February 14, 2011 expressed an unqualified opinion thereon.

MANAGEMENT’S REPORT ON INTERNAL CONTROL 

The Company has assessed the effectiveness of its internal control over financial reporting as of December 31, 2010 
based on criteria established by Internal Control – Integrated Framework issued by the Committee of Sponsoring 
Organizations of the Treadway Commission (“COSO Framework”).  The Company’s management is responsible for 
establishing and maintaining adequate internal controls over financial reporting.  The Company’s independent 
registered public accountants that audited the Company’s financial statements as of December 31, 2010 have issued 
an attestation report on management’s assessment of the effectiveness of the Company’s internal control over 
financial reporting, which appears on page F-4.  

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.  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 the inherent limitations, internal control over financial reporting may not 
prevent or detect misstatements.  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 the policies and procedures may deteriorate. 

The Company’s assessment of the effectiveness of its internal control over financial reporting included testing and 
evaluating the design and operating effectiveness of its internal controls.  In management’s opinion, the Company 
has maintained effective internal control over financial reporting as of December 31, 2010, based on criteria 
established in the COSO Framework.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM 

Board of Directors and Stockholders 
Administaff, Inc. 

We have audited Administaff, Inc.’s internal control over financial reporting as of December 31, 2010, based on 
criteria established in Internal Control—Integrated Framework issued by the Committee of Sponsoring 
Organizations of the Treadway Commission (the COSO criteria). Administaff, Inc.’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. Our 
responsibility is to express an opinion on the company’s internal control over financial reporting based on our audit.  

We conducted our audit in accordance with the standards of the Public Company Accounting Oversight Board 
(United States). 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. 

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 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. 

In our opinion, Administaff, Inc. maintained, in all material respects, effective internal control over financial 
reporting as of December 31, 2010, based on the COSO criteria. 

We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United 
States), the consolidated balance sheets of Administaff, Inc. as of December 31, 2010 and 2009, and the related 
Consolidated Statements of Operations, Stockholders’ Equity, and Cash Flows for each of the three years in the 
period ended December 31, 2010 of Administaff, Inc. and our report dated February 14, 2011 expressed an 
unqualified opinion thereon.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS 
December 31, 2010 

1.  Accounting Policies 

Description of Business 

Administaff, Inc. (the “Company”) is a human resource (“HR”) services company.  Our primary HR service 
is our professional employer organization (“PEO”) service, which provides a comprehensive Personnel Management 
SystemSM encompassing a broad range of services, including benefits and payroll administration, health and 
workers’ compensation insurance programs, personnel records management, employer liability management, 
employee recruiting and selection, employee performance management and employee training and development 
services to small and medium-sized businesses in strategically selected markets.  We were organized as a 
corporation in 1986 and have provided PEO services since inception. 

In addition to our PEO service, we provide business performance improvement services and software 

solutions to assist small to medium size companies.  These services include record keeping for defined contribution 
plans, recruiting and employee screening services, and software solutions for employee expense management, time 
and attendance, performance management, and organizational planning offered via desktop applications and 
software as a service (“SaaS”) delivery models. 

The Company provides its comprehensive service by entering into a co-employment relationship with its 

clients, under which the Company and its clients each take responsibility for certain portions of the employer-
employee relationship.  The Company and its clients designate each party’s responsibilities through its Client 
Services Agreement (“CSA”), under which the Company becomes the employer of its worksite employees for most 
administrative and regulatory purposes. 

As a co-employer of its worksite employees, the Company assumes most of the rights and obligations 

associated with being an employer.  The Company enters into an employment agreement with each worksite 
employee, thereby maintaining a variety of employer rights, including the right to hire or terminate employees, the 
right to evaluate employee qualifications or performance, and the right to establish employee compensation levels.  
Typically, the Company only exercises these rights in consultation with its clients or when necessary to ensure 
regulatory compliance.  The responsibilities associated with the Company’s role as employer include the following 
obligations with regard to its worksite employees: (i) to compensate its worksite employees through wages and 
salaries; (ii) to pay the employer portion of payroll-related taxes; (iii) to withhold and remit (where applicable) the 
employee portion of payroll-related taxes; (iv) to provide employee benefit programs; and (v) to provide workers’ 
compensation insurance coverage.  

In addition to its assumption of employer status for its worksite employees, the Company’s comprehensive 

service also includes other human resource functions for its clients to support the effective and efficient use of 
personnel in their business operations.  To provide these functions, the Company maintains a significant staff of 
professionals trained in a wide variety of human resource functions, including employee training, employee 
recruiting, employee performance management, employee compensation, and employer liability management.  These 
professionals interact and consult with clients on a daily basis to help identify each client’s service requirements and 
to ensure that the Company is providing appropriate and timely personnel management services. 

The Company provides its comprehensive service to small and medium-sized businesses in strategically 

selected markets throughout the United States.  During 2010, 2009 and 2008, revenues from the Company’s Texas 
markets represented 28%, 29% and 31%, while California represented 15%, 15% and 16% of the Company’s total 
revenues, respectively.

ADMINISTAFF, INC. 
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (continued) 

Revenue and Direct Cost Recognition 

The Company accounts for its PEO revenues in accordance with Accounting Standards Codification 
(“ASC”) 605-45, Revenue Recognition, Principal Agent Considerations.  The Company’s PEO revenues are derived 
from its gross billings, which are based on (i) the payroll cost of its worksite employees; and (ii) a markup computed 
as a percentage of the payroll cost.  The gross billings are invoiced concurrently with each periodic payroll of its 
worksite employees.  Revenues, which exclude the payroll cost component of gross billings, and therefore, consist 
solely of markup, are recognized ratably over the payroll period as worksite employees perform their service at the 
client worksite.  Revenues that have been recognized but not invoiced are included in unbilled accounts receivable 
on the Company’s Consolidated Balance Sheets. 

In determining the pricing of the markup component of the gross billings, the Company takes into 

consideration its estimates of the costs directly associated with its worksite employees, including payroll taxes, 
benefits and workers’ compensation costs, plus an acceptable gross profit margin.  As a result, the Company’s 
operating results are significantly impacted by the Company’s ability to accurately estimate, control and manage its 
direct costs relative to the revenues derived from the markup component of the Company’s gross billings. 

Consistent with its revenue recognition policy, the Company’s direct costs do not include the payroll cost of 

its worksite employees.  The Company’s direct costs associated with its revenue generating activities are primarily 
comprised of all other costs related to its worksite employees, such as the employer portion of payroll-related taxes, 
employee benefit plan premiums and workers’ compensation insurance costs. 

Segment Reporting 

 The Company operates one reportable segment under ASC 280, Segment Reporting. 

Principles of Consolidation 

The Consolidated Financial Statements include the accounts of Administaff, Inc. and its wholly owned 

subsidiaries.  Intercompany accounts and transactions have been eliminated in consolidation. 

Use of Estimates 

The preparation of financial statements in conformity with United States generally accepted accounting 

principles, requires management to make estimates and assumptions that affect the amounts reported in the financial 
statements and accompanying notes.  Actual results could differ from those estimates. 

Concentrations of Credit Risk 

Financial instruments that could potentially subject the Company to concentration of credit risk include 

accounts receivable and marketable securities.  

Cash, Cash Equivalents and Marketable Securities 

The Company invests its excess cash in federal government and municipal-based money market funds and 
debt instruments of U.S. municipalities.  All highly liquid investments with stated maturities of three months or less 
from date of purchase are classified as cash equivalents.  Liquid investments with stated maturities of greater than 
three months are classified as marketable securities in current assets.   

F-13 

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
ADMINISTAFF, INC. 
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (continued) 

The Company accounts for marketable securities in accordance with ASC 320, Investments – Debt and 
Equity Securities.  The Company determines the appropriate classification of all marketable securities as held-to-
maturity, available-for-sale or trading at the time of purchase, and re-evaluates such classification as of each balance 
sheet date.  At December 31, 2010 and 2009, all of the Company’s investments in marketable securities were 
classified as available-for-sale, and as a result, were reported at fair value.  Unrealized gains and losses are reported 
as a component of accumulated other comprehensive income (loss) in stockholders’ equity.  The amortized cost of 
debt securities is adjusted for amortization of premiums and accretion of discounts from the date of purchase to 
maturity.  Such amortization is included in interest income as an addition to or deduction from the coupon interest 
earned on the investments.  The Company uses the specific identification method of determining the cost basis in 
computing realized gains and losses on the sale of its available-for-sale securities. Realized gains and losses are 
included in other income. 

Fair Value of Financial Instruments 

The carrying amounts of cash, cash equivalents, accounts receivable and accounts payable approximate 

their fair values due to the short-term maturities of these instruments.  The carrying amount of the Company’s 
marketable securities approximate fair value due to the effective interest rates approximating market rates. 

Property and Equipment 

Property and equipment are recorded at cost and are depreciated over the estimated useful lives of the 

related assets using the straight-line method.  The estimated useful lives of property and equipment for purposes of 
computing depreciation are as follows: 

Buildings and improvements .........................................................................   5-30 years 
1-5 years 
Computer hardware and software, and acquired technologies .......................  
Software development costs...........................................................................  
3 years 
5-7 years 
Furniture and fixtures .....................................................................................  
20 years 
Aircraft ...........................................................................................................  

Software development costs relate primarily to software coding, system interfaces and testing of the 

Company’s proprietary professional employer information systems and are accounted for in accordance with ASC 
350-40, Internal Use Software. Capitalized software development costs are amortized using the straight-line method 
over the estimated useful lives of the software, generally three years. 

The Company accounts for its software products in accordance with ASC 985-20, Costs of Software to be 

Sold. This Topic establishes standards of financial accounting and reporting for the costs of computer software to be 
sold, leased, or otherwise marketed as a separate product or as part of a product or process, whether internally 
developed and produced or purchased.  

The Company periodically evaluates its long-lived assets for impairment in accordance with ASC 360-10, 

Property, Plant, and Equipment.  ASC 360-10 requires that an impairment loss be recognized for assets to be 
disposed of or held-for-use when the carrying amount of an asset is deemed to not be recoverable.  If events or 
circumstances were to indicate that any of the Company’s long-lived assets might be impaired, the Company would 
assess recoverability based on the estimated undiscounted future cash flows to be generated from the applicable 
asset.  In addition, the Company may record an impairment loss to the extent that the carrying value of the asset 
exceeded the fair value of the asset.  Fair value is generally determined using an estimate of discounted future net 
cash flows from operating activities or upon disposal of the asset.   

Goodwill and Other Intangible Assets 

The Company’s goodwill and intangible assets are subject to the provisions of ASC 350, Intangibles – 

Goodwill and Other.  Accordingly, goodwill and other indefinite-lived intangible assets are tested for impairment on 

F-14 

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
ADMINISTAFF, INC. 
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (continued) 

an annual basis or when indicators of impairment exist, and written down when impaired. As of December 31, 2010 
and 2009, no impairment write downs were necessary.  Furthermore, ASC 350 requires purchased intangible assets 
other than goodwill to be amortized over their useful lives unless these lives are determined to be indefinite. 
Administaff’s purchased intangible assets are carried at cost less accumulated amortization. Amortization is 
computed over the estimated useful lives of the respective assets, five to ten years.  

The following table provides the gross carrying amount and accumulated amortization as of December 31, 

2010 and 2009, for each class of intangible assets and goodwill (in thousands):

The Company’s amortization expense related to purchased intangible assets other than goodwill was 

$799,000 in 2010, $408,000 in 2009 and $340,000 in 2008, and is estimated to be $1.2 million in 2011 and 2012, 
$1.1 million in 2013 and 2014, and $900,000 in 2015. 

Health Insurance Costs 

The Company provides group health insurance coverage to its worksite employees through a national 

network of carriers including UnitedHealthcare (“United”), PacifiCare, Kaiser Permanente, Blue Shield of 
California, Hawaii Medical Service Association, Unity Health Plans and Tufts, all of which provide fully insured 
policies or service contracts.   

The policy with United provides the majority of the Company’s health insurance coverage.  As a result of 
certain contractual terms, the Company has accounted for this plan since its inception using a partially self-funded 
insurance accounting model.  Accordingly, Administaff records the costs of the United plan, including an estimate of 
the incurred claims, taxes and administrative fees (collectively the “Plan Costs”) as benefits expense in the 
Consolidated Statements of Operations.  The estimated incurred claims are based upon: (i) the level of claims 
processed during each quarter; (ii) estimated completion rates based upon recent claim development patterns under 
the plan; and (iii) the number of participants in the plan, including both active and COBRA enrollees.  Each 
reporting period, changes in the estimated ultimate costs resulting from claim trends, plan design and migration, 
participant demographics and other factors are incorporated into the benefits costs. 

Additionally, since the plan’s inception, under the terms of the contract, United establishes cash funding 

rates 90 days in advance of the beginning of a reporting quarter.  If the Plan Costs for a reporting quarter are greater 
than the premiums paid and owed to United, a deficit in the plan would be incurred and a liability for the excess 
costs would be accrued in the Company’s Consolidated Balance Sheet.  On the other hand, if the Plan Costs for the 
reporting quarter are less than the premiums paid and owed to United, a surplus in the plan would be incurred and

the Company would record an asset for the excess premiums in its Consolidated Balance Sheet.  The terms of the 
arrangement require Administaff to maintain an accumulated cash surplus in the plan of $9.0 million, which is 
reported as long-term prepaid insurance.  As of December 31, 2010, Plan Costs were less than the net premiums paid 
and owed to United by $28.9 million.  As this amount is in excess of the agreed-upon $9.0 million surplus 
maintenance level, the $19.9 million balance is included in prepaid insurance, a current asset, in the Company’s 
Consolidated Balance Sheet.  The premiums owed to United at December 31, 2010, were $12.1  million, which is 
included in accrued health insurance costs, a current liability in the Company’s Consolidated Balance Sheet. 

Workers’ Compensation Costs 

The Company’s workers’ compensation coverage has been provided through an arrangement with the ACE 

Group of Companies (“the ACE Program”) since 2007.  The ACE Program is fully insured in that ACE has the 
responsibility to pay all claims incurred regardless of whether the Company satisfies its responsibilities.  Through 
September 30, 2010, the Company bore the economic burden for the first $1 million layer of claims per occurrence 
and the insurance carrier was and remains responsible for the economic burden for all claims in excess of such first 
$1 million layer.    

Effective for the ACE Program year beginning on October 1, 2010, in addition to the Company bearing the 

economic burden for the first $1 million layer of claims per occurrence, the Company will also bear the economic 
burden for those claims exceeding $1 million, up to a maximum aggregate amount of $5 million per policy year.   

Because the Company bears the economic burden for claims up to the levels noted above, such claims, 

which are the primary component of the Company’s workers’ compensation costs, are recorded in the period 
incurred.  Workers’ compensation insurance includes ongoing health care and indemnity coverage whereby claims 
are paid over numerous years following the date of injury.  Accordingly, the accrual of related incurred costs in each 
reporting period includes estimates, which take into account the ongoing development of claims and therefore 
requires a significant level of judgment.     

The Company employs a third party actuary to estimate its loss development rate, which is primarily based 

upon the nature of worksite employees’ job responsibilities, the location of worksite employees, the historical 
frequency and severity of workers compensation claims, and an estimate of future cost trends.  Each reporting 
period, changes in the actuarial assumptions resulting from changes in actual claims experience and other trends are 
incorporated into the Company’s workers’ compensation claims cost estimates.  During the year ended December 
31, Administaff reduced accrued workers’ compensation costs by $6.2 million and $5.7 million, respectively, in 
2010 and 2009, for changes in estimated losses related to prior reporting periods.  Workers’ compensation cost 
estimates are discounted to present value at a rate based upon the U.S. Treasury rates that correspond with the 
weighted average estimated claim payout period (the average discount rates utilized in 2010 and 2009 were 1.4% 
and 1.8%, respectively) and are accreted over the estimated claim payment period and included as a component of 
direct costs in the Company’s Consolidated Statements of Operations.

The current portion of accrued workers’ compensation costs at December 31, 2010 and 2009, includes 

$877,000 and $613,000, respectively, of workers’ compensation administrative fees. 

As of December 31, the undiscounted accrued workers’ compensation costs were $111.5 million in 2010 

and $103.8 million in 2009. 

At the beginning of each policy period, the insurance carrier establishes monthly funding requirements 
comprised of premium costs and funds to be set aside for payment of future claims (“claim funds”).  The level of 
claim funds is primarily based upon anticipated worksite employee payroll levels and expected workers 
compensation loss rates, as determined by the insurance carrier.  Monies funded into the program for incurred claims 
expected to be paid within one year are recorded as restricted cash, a short-term asset, while the remainder of claim 
funds are included in deposits, a long-term asset in the Company’s Consolidated Balance Sheets.   In 2010, the 
Company received $15.6 million for the return of excess claim funds related to the ACE program, which reduced 
deposits.  As of December 31, 2010, the Company had restricted cash of $41.2 million and deposits of $51.7 million. 

The Company’s estimate of incurred claim costs expected to be paid within one year are recorded as 
accrued workers’ compensation costs and included in short-term liabilities, while its estimate of incurred claim costs 
expected to be paid beyond one year are included in long-term liabilities on the Company’s Consolidated Balance 
Sheets. 

Stock-Based Compensation 

At December 31, 2010, the Company has three stock-based employee compensation plans.  The Company 

accounts for these plans under the recognition and measurement principles of ASC 718, Compensation – Stock 
Compensation, which requires all share-based payments to employees, including grants of employee stock options, 
to be recognized in the income statement based on their fair values.   

The Company generally makes annual grants of restricted and unrestricted stock under its stock-based 

incentive compensation plans to its directors, officers and other management. Restricted stock grants to officers and 
other management vest over three to five years from the date of grant.  Annual stock grants issued to directors are 
100% vested on the grant date.  Shares of restricted stock are based on fair value on date of grant and the associated 
expense net of estimated forfeitures is recognized over the vesting period.   

Company-Sponsored 401(k) Plans 

Under the Company’s 401(k) plan for corporate employees (the “Corporate Plan”), the Company matched 
50% of eligible corporate employees’ contributions, up to 6% of the employee’s eligible compensation in 2010 and

2009, and 100% of eligible corporate employees’ contributions, up to 6% of the employee’s eligible compensation in 
2008.  Under the Company’s separate 401(k) plan for worksite employees (the “Worksite Employee Plan”), the 
match percentage for worksite employees ranges from 0% to 6%, as determined by each client company.  Matching 
contributions under the Corporate Plan and the Worksite Employee Plan are immediately vested.  During 2010, 2009 
and 2008, the Company made matching contributions to the Corporate and Worksite Employee Plans of $49.6 
million, $47.7 million and $52.0 million, respectively.  Of these contributions, $47.5 million, $45.1 million and 
$47.3 million were made under the Worksite Employee Plan on behalf of worksite employees.  The remainder 
represents matching contributions made under the Corporate Plan on behalf of corporate employees. 

Advertising 

The Company expenses all advertising costs as incurred. 

Income Taxes 

The Company uses the liability method in accounting for income taxes.  Under this method, deferred tax 

assets and liabilities are determined based on differences between financial reporting and income tax carrying 
amounts of assets and liabilities and are measured using the enacted tax rates and laws in effect when the differences 
are expected to reverse. 

Reclassifications 

Certain prior year amounts have been reclassified to conform to the 2010 presentation. 

Subsequent Events 

The company has evaluated subsequent events through the date the financial statements were issued and 

filed with the Securities and Exchange Commission. 

New Accounting Pronouncements 

We believe that we have implemented the accounting pronouncements with a material impact on our 

financial statements and do not believe there are any new or pending announcements that will materially impact our 
financial position or results of operations.

The Company’s cash and overnight holdings fluctuate based on the timing of the client’s payroll processing 
cycle.  Included in the cash balance as of December 31, 2010 and December 31, 2009, are $128.8 million and $115.4 
million, respectively, in withholdings associated with federal and state income taxes, employment taxes and other 
payroll deductions, as well as $8.1 million and $13.1 million, respectively, in client prepayments. 

The Company accounts for its financial assets in accordance with ASC 820, Fair Value Measurement.  This 

standard defines fair value, establishes a framework for measuring fair value and expands disclosures about fair 
value measurements.  The fair value measurement disclosures are grouped into three levels based on valuation 
factors: 

•  Level 1 - quoted prices in active markets using identical assets;  
•  Level 2 - significant other observable inputs, such as quoted prices for similar assets or liabilities, 

quoted prices in markets that are not active, or other observable inputs, and 

•  Level 3 - significant unobservable inputs.

The municipal bond securities valued as Level 2 investments are primarily pre-refunded municipal bonds 

that are secured by escrow funds containing U.S. government securities. Valuation techniques used by the Company 
to measure fair value for these securities during the period consisted primarily of third party pricing services that 
utilized actual market data such as trades of comparable bond issues, broker/dealer quotations for the same or similar 
investments in active markets and other observable inputs.

Accounts Receivable 

The Company’s accounts receivable is primarily composed of trade receivables and unbilled receivables.  

The Company’s trade receivables, which represent outstanding gross billings to customers, are reported net of 
allowance for doubtful accounts of $988,000 and $1.3 million as of December 31, 2010 and 2009, respectively.  The 
Company establishes an allowance for doubtful accounts based on management’s assessment of the collectability of 
specific accounts and by making a general provision for other potentially uncollectible amounts.  

The Company makes an accrual at the end of each accounting period for its obligations associated with the 

earned but unpaid wages of its worksite employees and for the accrued gross billings associated with such wages.  
These accruals are included in accrued worksite employee payroll cost and unbilled accounts receivable; however, 
these amounts are presented net in the Consolidated Statements of Operations.  The Company generally requires 
clients pay invoices for service fees no later than one day prior to the applicable payroll date.  As such, the Company 
generally does not require collateral.  Customer prepayments directly attributable to unbilled accounts receivable 
have been netted against such receivables as the gross billings have been earned and the payroll cost has been 
incurred, thus the Company has the legal right of offset for these amounts.  As of December 31, 2010 and 2009, 
unbilled accounts receivable consisted of the following:

Acquisitions 

The Company accounts for its acquisitions in accordance with ASC 805, Business Combinations, which 

requires allocation of the purchase price to tangible and identifiable intangible assets acquired and liabilities assumed 
based on the fair value at the date of purchase.  The purchase price in excess of the identifiable assets and liabilities 
is recorded to goodwill, $8.6 million in 2010.  All acquisition related costs are expensed as incurred and recorded in 
operating expenses.  The Company includes operations associated with acquisitions from the date of acquisition 
forward.

As a result of nonqualified stock option exercises, disqualifying dispositions of certain employee incentive 

stock options and vesting of restricted stock awards, the Company had net income tax benefit of $25,000 in 2010,  
net income tax expense of $372,000 in 2009, and net income tax benefit of $821,000 in 2008, respectively.  The 
income tax benefit or expense was reported as a component of additional paid-in capital. 

The reconciliation of income tax expense computed at U.S. federal statutory tax rates to the reported 

income tax expense from continuing operations is as follows:

The Company has capital loss carryforwards totaling approximately $510,000 that will expire during 2012, 

but can only be used to offset future capital gains.  The Company has a valuation allowance of $510,000 against 
these related deferred tax assets as it is uncertain that the Company will be able to utilize the capital loss 
carryforwards prior to their expiration.   

The Company recognizes interest and penalties related to uncertain tax positions in income tax expense.  As 
of December 31, 2010, 2009 and 2008, the Company made no provisions for interest or penalties related to uncertain 
tax positions.  The tax years 2007 through 2010 remain open to examination by the Internal Revenue Service of the 
United States.

Stockholders’ Equity 

The Company’s Board of Directors (the “Board”) has authorized a program to repurchase up to 13,500,000 

shares of the Company’s outstanding common stock.  The purchases are to be made from time to time in the open 
market or directly from stockholders at prevailing market prices based on market conditions or other factors.  The 
Company  repurchased 271,739 shares under this program during 2010.  In addition, 97,419 shares were withheld 
during 2010 to satisfy tax withholding obligations for the vesting of restricted stock awards.  These purchases are not 
subject to the repurchase program.  During 2009, the Company did not repurchase shares under the repurchase 
program; however, 87,932 shares were withheld during 2009 to satisfy tax withholding obligations for the vesting of

restricted stock awards.  As of December 31, 2010, the Company had repurchased 12,360,607 shares under this 
program at a total cost of approximately $243.7 million.  As a result, the Company has the authorization to 
repurchase an additional 1,139,393 shares. 

During each quarter of 2010 and 2009 the Board declared a dividend of $0.13 per share of common stock , 
resulting in a total of $13.5 million and $13.3 million in dividend payments paid by the Company in 2010 and 2009, 
respectively. 

At December 31, 2010, 20 million shares of preferred stock were authorized and were designated as Series 

A Junior Participating Preferred Stock that is reserved for issuance on exercise of preferred stock purchase rights 
under Administaff’s Share Purchase Rights Plan (the “Rights Plan”).  Each issued share of the Company’s common 
stock has one preferred stock purchase right attached to it.  No preferred shares have been issued and the rights are 
not currently exercisable.  The Rights Plan expires on November 13, 2017. 

8.   

Incentive Plans 

The Administaff, Inc. 1997 Incentive Plan, as amended, and the 2001 Incentive Plan, as amended, 
(collectively, the “Incentive Plans”) provide for options and other stock-based awards that may be granted to eligible 
employees and non-employee directors of the Company or its subsidiaries.  The 2001 Incentive Plan is currently the 
only Administaff plan under which stock-based awards may be granted.  No new stock-based awards may be made 
under any other plan.  The Incentive Plans are administered by the Compensation Committee of the Board of 
Directors (the “Committee”).  The Committee has the power to determine which eligible employees will receive 
awards, the timing and manner of the grant of such awards, the exercise price of stock options (which may not be 
less than market value on the date of grant), the number of shares and all of the terms of the awards.  The Board may 
at any time amend or terminate the Incentive Plans.  However, no amendment that would impair the rights of any 
participant, with respect to outstanding grants, can be made without the participant’s prior consent.  Stockholder 
approval of amendments to the Incentive Plans is necessary only when required by applicable law or stock exchange 
rules.  The 1997 Incentive Plan expired on April 24, 2005; therefore no new grants may be made under the Plan.  At 
December 31, 2010, 1,041,716 shares of common stock were available for future grants under the 2001 Incentive 
Plan.  The Incentive Plans permit stock options, including nonqualified stock options and options intended to qualify 
as “incentive stock options” within the meaning of Section 422 of the Internal Revenue Code (the “Code”), stock 
awards, phantom stock awards, stock appreciation rights, performance units, and other stock-based awards and cash 
awards, all of which may or may not be subject to the achievement of one or more performance objectives.  The 
purposes of the Incentive Plans generally are to retain and attract persons of training, experience and ability to serve 
as employees of the Company and its subsidiaries and to serve as non-employee directors of the Company, to 
encourage the sense of proprietorship of such persons and to stimulate the active interest of such persons in the 
development and financial success of the Company and its subsidiaries. 

The Administaff Nonqualified Stock Option Plan (the “Nonqualified Plan”) provided for options to 
purchase shares of the Company’s common stock that were granted to employees who were officers.  An aggregate 
of 3,600,000 shares of common stock of the Company were authorized to be issued under the Nonqualified Plan.  
Although there are unissued shares remaining, no new awards may be granted under the Nonqualified Plan.  The 
Committee may at any time terminate or amend the Nonqualified Plan, provided that no such amendment may 
adversely affect the rights of optionees with regard to outstanding options.

Restricted Stock Awards 

Restricted common shares, under fixed plan accounting, are generally measured at fair value on the date of 
grant based on the number of shares granted, estimated forfeitures and the quoted price of the common stock.  Such 
value is recognized as compensation expense over the corresponding vesting period, three to five years for the 
Company’s shares currently outstanding.  The Company has recognized $8.1 million, $10.1 million and $10.0 
million of compensation expense associated with the restricted stock awards in 2010, 2009 and 2008, respectively.  
As of December 31, 2010, unrecognized compensation expense associated with the unvested shares outstanding was 
$8.3 million and is expected to be recognized over a weighted average period of 22 months.

Net Income Per Share 

The Company utilizes the two-class method to compute net income per share.  The two-class method 

allocates a portion of net income to participating securities, which include unvested awards of share-based payments 
with non-forfeitable rights to receive dividends.  Net income allocated to unvested share-based payments is excluded 
from net income allocated to common shares.  Basic net income per share is computed by dividing net income 
allocated to common shares by the weighted average number of common shares outstanding during the period.  
Diluted net income per share is computed by dividing net income allocated to common shares by the weighted 
average number of common shares outstanding during the period, plus the dilutive effect of outstanding stock 
options. 

The following table summarizes the net income allocated to common shares and the basic and diluted 
shares used in the net income per share computations for the years ended December 31, 2010, 2009 and 2008:

Leases 

The Company leases various office facilities, furniture, equipment and vehicles under operating lease 

arrangements, some of which contain rent escalation clauses.  Most of the leases contain purchase and/or renewal 
options at fair market and fair rental value, respectively.  Rental expense relating to all operating leases was $14.0 
million, $14.1 million and $12.1 million in 2010, 2009 and 2008, respectively.  At December 31, 2010, future

The Company is a defendant in various lawsuits and claims arising in the normal course of business.  

Management believes it has valid defenses in these cases and is defending them vigorously.  While the results of 
litigation cannot be predicted with certainty, except as set forth below, management believes the final outcome of 
such litigation will not have a material adverse effect on the Company’s financial position or results of operations. 

As a result of a 2001 corporate restructuring, we filed for a transfer of our state unemployment tax reserve 

account with the Employment Development Department of the State of California (“EDD”).  The EDD approved our 
request for transfer of the reserve account in May 2002 and also notified the Company of its new contribution rates 
based upon the approved transfer.  In December 2003, the Company received a Notice of Duplicate Accounts and 
Notification of Assessment (“Notice”) from the EDD.  The Notice stated that the EDD was collapsing the accounts 
of the Company’s subsidiaries into the account of the entity with the highest unemployment tax rate.  The Notice 
also retroactively imposed the higher unemployment insurance rate on all of the Company’s California employees 
for 2003, resulting in an assessment of $5.6 million.  In January 2004, the Company filed petitions with an 
administrative law judge of the California Unemployment Insurance Appeals Board (“ALJ”) to protest the validity of 
the Notice, asserting several procedural and substantive defenses.  The Company’s appeal is still pending and no 
date has been set for a hearing.   

One procedural defense included in the Company’s appeal asserts that EDD failed to meet the statutory 

requirement related to serving a proper notice within the stipulated time frame and that all of the statutes of

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (continued) 

limitations concerning EDD’s ability to reassess or modify unemployment tax rates for the periods addressed in the 
Notice had expired (“Notification Defense”).  On November 18, 2010, the 3rd Circuit Court of California (the 
“Appeals Court”) issued a ruling in favor of EDD regarding a dispute involving a taxpayer who made arguments 
similar to the Company’s Notification Defense (“Screaming Eagle Case”). In the Screaming Eagle Case, the Appeals 
Court upheld a trial court decision which held that the EDD did follow proper procedures when it assessed the 
taxpayer.  The taxpayer has appealed the Screaming Eagle Case to the Supreme Court of California. If the Appeals 
Court’s decision in the Screaming Eagle Case is  ultimately upheld, it would potentially eliminate Administaff’s 
Notification Defense.  While the specific facts and circumstances of the Company’s dispute are not identical to the 
Screaming Eagle Case, the Screaming Eagle Case does call into question the Company’s Notification Defense, 
pending final determination by the Supreme Court of California.  In addition to the Notification Defense, the 
Company will continue to vigorously assert its additional defenses. If the Company does not ultimately prevail in its 
arguments and the assessment is upheld, the Company may recognize an increase in its payroll tax expense in a 
future period.

Subsequent Event 

In January 2011, the Company acquired certain assets from Human Concepts, a provider of workforce 

decision support solutions.  Administaff acquired ownership of the OrgPlus desktop software product line, targeted 
at small and medium-sized businesses, and its associated customer base, as well as a source code license for a SaaS 
based version. OrgPlus facilitates creation, management and communication of detailed organizational charts. The 
acquisition represents Administaff’s continued business strategy to expand the sales opportunity of its human 
resource services as well as the solutions available to the Company’s current and target clients.  The Company paid 
$10.8 million upon the closing of the transaction and expects to pay an additional $1.2 million in 2011 based on the 
terms of the agreement.

EBITDA represents net income computed in accordance with generally accepted accounting principles (“GAAP”), plus 
interest  expense,  income  tax  expense,  depreciation  and  amortization  expense.  Administaff  management  believes 
EBITDA is often a useful measure of the company’s operating performance, as it allows for additional analysis of the 
company’s operating results separate from the impact of taxes and capital and financing transactions on earnings. 

EBITDA is not a financial measure prepared in accordance with GAAP and may be different from similar measures used 
by other companies.  EBITDA should not be considered as a substitute for, or superior to, measures of financial 
performance prepared in accordance with GAAP.  Administaff includes EBITDA in this report because the Company 
believes it is useful to investors in allowing for greater transparency related to the Company’s operating performance 
during the periods presented.  Investors are encouraged to review the reconciliation of the non-GAAP financial measures 
used in this report to the most directly comparable GAAP financial measure as provided in the tables above.
