Administaff made p&,ress 
in 2006 understanding the unique needs of middle-market clients with 150 to 2,000 employees. 
Despite the enormous potential, no HR buslness has developed a successful sales and service outsourcing model for mlddle- 
market cornpaniesAdrninistaff is dedicated to this goal and overcoming any challenges In the process. Every aspect of meeting 
the speclaltzed HR needs of these companies Is being examined as we reengineer our middlemarket~nltiattve to make k as 
M e t &   a pwslble. 

En h a n d  R,ecruiting 4ervi~es 
In early 2007,  AdminIstaff announted the expansion of its resulting servlces to help d i e m  attract and retain quality employees 
In the face of a forecast shortfall betwegn a fa[llng labor supply and increasing worker demand in the coming years.8~ enhancing 
our Infrastructure and Increasing stamng levels In this area, we can provide cllmts with a teal cornpetltlve advantage In meeting 
this growing demand. In addition, the Company can price those services In a way that boosts Administaff profits while offering 
mat1 and medium-$iM buslmsses a substantlal discount from what they often pay IndMduatly for similar services. 

In cloalng, I warn to extend my sincere gratitude to our corporate 
staff for their dedication, exern piifying the servant attirude that 
sets AdmlnIstaff apart from many other service organIratkm. 
These employees performed admirably not only at work, hut also 
thruugh-the community-involvement programs that are central 
tot-he Administaff culture. In addition ta serving the needs of our 
clients, Administaff corprate employees poured 27,219 volunteer 
hours into community-involvement activities, an increase of 25 
percent over 2005.1 would also Ike to thank our huard of directors 
fw their ValuabIe guidance and active support that has been vital 
to the accomplishment of the Admlnlstaff misston. We eagerly 
await the opportunities ahead from a strong financial 
positlon and as an industry leader wlth talented and

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,” 
including the factors discussed under the caption “Factors That May Affect Future Results and the Market Price of 
Common Stock,” beginning on page 38. 

ITEM 1.   BUSINESS. 

General 

Administaff is a professional employer organization (“PEO”) that 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 2003, we formed Administaff Retirement Services, LP, 
which currently performs recordkeeping services for defined contribution plans.  In December 2005, we acquired 
HRTools.com, an online portal for human resource products, services and information, as well as small business 
software applications related to job descriptions, performance reviews, and personnel policies and procedures. 

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 the Company’s Web site address is 
http://www.administaff.com.  Our stock is traded on the New York Stock Exchange under the symbol “ASF.”  
Periodic 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 Web site free of charge as soon as reasonably practicable 
after such material is electronically filed with, or furnished to, the SEC. 

Our Personnel Management System 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 that 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 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.

- 2 - 

 
 
 
 
 
 
 
 
 
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, 2006, we had 41 sales offices in 22 markets.  We paid an average of 104,325 worksite 
employees in the fourth quarter of 2006.  Our long-term strategy is to operate approximately 90 sales offices located 
in 40 strategically selected markets.  We opened three new sales offices and entered one new market in 2006. We 
intend to open eight new sales offices, including two new markets, in 2007.   

Our national expansion strategy also includes regionalized data processing for payroll and benefits 

transactions and localized face-to-face human resources service.  As of December 31, 2006, we have four service 
centers, which when fully staffed will provide the capacity to serve approximately 160,000 worksite employees.  In 
addition, we have human resources and client service personnel located in a majority of our 22 sales markets.   

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 broad aspects of the employer/employee relationship.  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. 

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 health care 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, 31 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 31 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 1987 (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)*; 

* And similar state laws 

•  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; and 

•  State workers’ compensation 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. 

- 4 - 

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
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 types of coverage:  

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

The group health plan includes medical, dental, vision, a worklife program and a prescription drug 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 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.  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 those employment-related responsibilities that are the responsibility of the client or we 
share with our clients, we can 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 workers’ compensation claims.  We also provide guidance to clients for avoiding liability claims for 
discrimination, sexual harassment and civil rights violations, and participate in termination decisions to attempt to 
minimize liability on those grounds.  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 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.

Client Service Agreement 

All PEO clients execute Administaff’s Client Service Agreement (“CSA”).  The CSA generally provides for 

an on-going relationship, subject to termination by Administaff or the client upon 30 or 60 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.  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 improved 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 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 the purposes of 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 CSA is 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; 
•  Compliance with COBRA, HIPAA and ERISA (for each employee benefit plan sponsored solely by Administaff ), 
as well as monitoring changes in other governmental regulations governing the 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; 

•  Assignment to, and ownership of, all client intellectual property rights; 
•  Compliance with OSHA regulations, EPA regulations, FLSA, 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, FMLA, the Consumer Credit Protection Act, and immigration laws and 
regulations. 

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.  We maintain employers’ practice liability insurance coverages (including coverages for our 
clients) to manage our exposure for these types of 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. 

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.   

Customers 

Administaff provides 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 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.  For the year ended 
December 31, 2006, Houston, our original market, accounted for approximately 19% of our revenues, with other 
Texas markets contributing an additional 17%.  By region, our revenue growth over 2005 and revenue distribution 
for the year ended December 31, 2006 were as follows:

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

certain specified NAICS (North American Industry Classification System) codes, formerly known as Standard 
Industrial Classification codes, essentially eliminating certain industries we believe present a higher employer risk 
such as employee injury, high turnover or litigation.  All prospective 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: 

- 8 - 

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
•  Computer and information services – 18%; 
•  Finance, insurance and real estate – 15%; 
•  Management, administration and consulting services – 13%; 
•  Manufacturing –  8%; 
•  Construction – 8%; 
•  Medical services – 8%; 
•  Wholesale trade – 7%; 
•  Engineering, accounting and legal services – 7%; 
•  Retail trade – 5%; 
•  Transportation – 2%; and 
•  Other – 9%. 

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 2006 and 2005, our retention rate was approximately 80%. 

Administaff’s client retention record over the last five years reflects that approximately 70% of our clients remain for 
more than one year, and that the retention rate improves for clients who remain with us for longer periods, up to 
approximately 80% for clients in their fifth year with Administaff.  The average annual retention rate over the last 
five years was approximately 77%.  Client attrition is attributable to a variety of factors, including: (i) client non-
renewal due to price 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, 2006, we had 41 sales offices located in 22 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 
follows:

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.   

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 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 PEO service and to more successfully reach our target market. 

In 2004, we entered into an agreement with the Professional Golf Association Champions Tour to become 

the title sponsor of the annual Administaff Small Business Classic professional golf tournament held in Houston, 
Texas.  In addition, we have entered into a lifetime arrangement with Arnold Palmer to be our national spokesperson. 
 Our marketing campaigns use this event and the relationship with Mr. Palmer 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 clients, and 
ultimately, a predictable number of client census reports.  A prospective 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.  

Competition 

Administaff provides 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.  This full-service approach is exemplified by 

- 10 - 

 
 
 
 
 
 
 
 
 
 
 
 
our commitment to provide a 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 2003 through 2005 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 2003 through 2005, our staff support ratio averaged 50% higher than the PEO 
industry average, while gross profit per worksite employee and operating income per worksite employee both 
exceeded industry averages by 141%. 

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 PEOs in the United States.  Our largest national competitors include Gevity HR and PEO 
divisions of large business services companies such as Automatic Data Processing, Inc. and Paychex, Inc.  In 
addition, we compete to some extent with fee-for-service providers such as payroll processors and human resource 
consultants and face competition from large regional PEOs in certain areas of the country.  As Administaff and other 
large PEOs 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 and American International Group 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 UnitedHealthcare (“United”), Cigna Healthcare, PacifiCare, Kaiser Permanente, Blue Cross and 
Blue Shield of Georgia, Blue Shield of California, Hawaii Medical Service Association and Tufts, all of which 
provide fully insured policies or service contracts.  The policy with United provides approximately 78% of our 
health insurance coverage and automatically renews annually, 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 24. 

Our workers’ compensation coverage (the “AIG Program”) is currently provided through selected member 
insurance companies of American International Group, Inc. (“AIG”).  Under our arrangement with AIG, we bear the 
economic burden for the first $1 million layer of claims per occurrence.  AIG bears the economic burden for all 
claims in excess of such first $1 million layer.  The AIG Program is a fully insured policy whereby AIG 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 AIG, 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 26. 

Information Technology 

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

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

- 11 - 

 
 
 
 
 
 
 
 
 
 
 
  
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 is a transaction processing system that allows us to process a high volume of payroll, 

invoice, and bid transactions that meet the specific needs of our clients and prospects.  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.   

During 2006, we completed a project to develop a new benefits administration system that allows for 

increased reporting flexibility to our clients and prospects.  The system was developed internally and placed into 
production during the fourth quarter of 2006. 

The Employee Service Center is our proprietary web-based PEO service delivery platform.  With its 

integration into AIMS, the ESC is designed to provide automated, personalized PEO content and services to our 
clients and worksite employees.  For a description of the functionality provided through the ESC, please read “PEO 
Services – Employee Service Center” on page 6.   

Administaff’s primary data center is located at our corporate headquarters in Kingwood, Texas (a suburb of 
Houston).  Substantially all of our business applications, telecommunications equipment and network equipment are 
hosted in this data center.  We maintain a disaster recovery data center in our Dallas service center. This data center 
is fully equipped with the hardware and software necessary to run all of our critical business applications and has 
sufficient capacity to handle all of our operations for short periods of time, if required.  Periodically, we perform 
testing to ensure the disaster recovery capabilities remain effective and available. 

We have invested substantially in our network infrastructure to ensure appropriate connectivity exists 

between our service centers in Atlanta, Dallas, Houston and Los Angeles, our district sales offices and our corporate 
offices, and to provide appropriate Internet connectivity to conduct business through the Employee Service Center.  
The network infrastructure is provided through industry standard core network hardware and via high-speed network 
services provided by multiple vendors. 

Industry Regulation 

Administaff’s operations are affected by numerous federal and state laws relating to tax 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, 31 states have passed laws that recognize PEOs or require 
licensing, registration or certification requirements for PEOs, and several others are considering such regulation. 

- 12 - 

 
 
 
 
 
 
 
 
 
 
 
 
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 with our 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, prescription and worklife programs;  
a welfare benefits plan which includes life insurance and disability programs;  
a health care flexible spending plan;  
an educational assistance program; and  
an adoption assistance program.   

Generally, employee benefit plans are subject to provisions of both the Internal Revenue Code and ERISA. 

Employer Status.  In order to qualify for favorable tax treatment under the Code, the 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 
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). 

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. 

- 13 - 

 
 
 
 
 
 
 
 
 
 
 
 
 
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 Plan.  The Company’s 401(k) Retirement Plan is 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. 

Federal 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.  

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 prior years’ 
compensation experience in each state.  In addition, states have the ability under law to increase unemployment tax 
rates to cover deficiencies in the unemployment tax funds.  Rate notices are typically provided by the states during 

- 14 - 

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
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.  For additional discussion regarding our SUI tax rates in 
recent years, please read Item 7. “Management Discussion and Analysis of Financial Condition and Results of 
Operations - Critical Accounting Policies and Estimates – State Unemployment Taxes” on page 25. 

State Regulation 

While many states do not explicitly regulate PEOs, 31 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 31 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 1,700 corporate office and sales employees as of December 31, 2006.  We believe 

our relations with our corporate office and sales employees are good.  None of our corporate office and sales 
employees are covered by a collective bargaining agreement. 

Intellectual Property 

Administaff currently has registered trademarks and certain copyrights.  Although the Administaff mark is 
the most material trademark to our business, our trademarks as a whole are also of considerable importance to us.  
Additionally, our acquisition of certain assets from KnowledgePoint, a subsidiary of Recruitmax, in December 2005 
included trademarks and other intellectual property.

ITEM 1A.  RISK FACTORS. 

Information on the Company’s risk factors is included in Item 7. “Management’s Discussion and Analysis 
of Financial Condition and Results of Operations — Factors that May Affect Future Results and the Market Price of 
Common Stock” on page 38. 

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 expansion goals.  We will continue to evaluate the need for additional 
facilities based on the rate of growth in worksite employees, the geographic distribution of the worksite employee 
base and our long-term service delivery requirements. 

Corporate Headquarters 

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 primary data processing center.   

Service Centers 

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

The Atlanta service center, which currently services approximately 27% of our worksite employee base, is 
located in a 40,000 square foot leased facility.  This facility, which is under lease until 2014, is designed to service 
approximately 40,000 worksite employees at full capacity. 

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

located in a 40,000 square foot leased facility, which also serves as our backup data processing and disaster recovery 
center.  This facility, which is under lease until 2008, is designed to service approximately 40,000 worksite 
employees at full capacity. 

The Houston service center, which currently services approximately 27% of our worksite employee base, is 

located in a 58,000 square foot leased facility.  This facility, which is under lease until 2014, is designed to service 
approximately 40,000 worksite employees at full capacity. 

The Los Angeles service center, which currently services approximately 23% of our worksite employee 

base, is located in a 45,000 square foot leased facility.  This facility, which is under lease until 2012, is designed to 
service approximately 40,000 worksite employees at full capacity. 

Sales Offices 

As of December 31, 2006, we had sales and service personnel in 31 facilities located in 22 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, 2006, we had 41 sales offices in these 22 
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.

ITEM 3.  LEGAL PROCEEDINGS. 

Other than as set forth below, 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.  

Class Action Litigation 

On June 13, 2003, a class action lawsuit was filed against the Company in the United States District Court 

for the Southern District of Texas on behalf of purchasers of the Company’s common stock alleging violations of the 
federal securities laws.  After that date, six similar class actions were filed against the Company in that court.  Those 
lawsuits also named as defendants certain of the Company’s officers and directors.  In May 2004, the lead plaintiff 
filed its Consolidated Complaint, which amended and consolidated the seven previously filed cases.  In June 2004, 
the Company filed a motion to dismiss the Consolidated Complaint.  On March 30, 2006, the court granted the 
Company’s motion to dismiss and thereafter entered a final order of dismissal with prejudice.  The lead plaintiff did 
not file a notice of appeal by the deadline to do so.  Accordingly, this matter is now concluded. 

State Unemployment Taxes 

As a result of a 2001 corporate restructuring, we filed for a transfer of our 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 us of our new contribution rates based upon the 
approved transfer.  In December 2003, we 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 our 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 our California employees for 2003, resulting in an assessment of $5.6 million. 
In January 2004, we filed a petition with an administrative law judge of the California Unemployment Insurance 
Appeals Board (“ALJ”) to protest the validity of the Notice.  Pending a resolution of our protest, in the fourth quarter 
of 2003 we accrued and recorded at the higher assessed rate for all of 2003. 

In June 2004, we agreed to settle our dispute with the EDD for $3.3 million.  Based upon receipt of written 

acknowledgement of this agreement, we reduced our accrued payroll tax liability and payroll tax expense by $2.3 
million during the quarter ended June 30, 2004.  The settlement was subject to the final approval by EDD’s legal 
department, the California Attorney General’s office and the ALJ.  In October 2004, the legal department of the 
EDD verbally indicated they considered the previously agreed-upon settlement amount to be insufficient and 
suggested a settlement amount of $5.2 million.  We continued discussions with the State of California, but in 
February 2005, we were notified that the EDD had rejected our settlement offer, and the matter will proceed with the 
appeals process with the ALJ.  As of October 31, 2006, all of the statutes of limitations concerning notices to modify 
unemployment tax rates for the periods addressed in the Notice had expired.  We believe the EDD failed to meet the 
statutory requirement related to serving a proper notice within the stipulated time frame; therefore, we believe it is no 
longer probable that the amount accrued for the California unemployment tax matter will be incurred.  Accordingly, 
we reduced the state unemployment tax accrual by $3.3 million during 2006.  

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

No matters were submitted to a vote of our security holders, through solicitation of proxies or otherwise, 

during the quarter ended December 31, 2006.

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 this 
Item 7 under “Factors that May Affect Future Results and the Market Price of Common Stock” on page 38 and the 
uncertainties set forth from time to time in our other public reports and filings and public statements. 

Overview  

We 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 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 number of worksite employees paid as our unit of measurement in analyzing 
and discussing our results of operations. 

Our key objective for 2006 was to continue to accelerate the growth in the number of paid worksite 

employees while appropriately pricing our service offering.  We ended 2006 averaging 104,325 paid worksite 
employees in the fourth quarter, which represents a 10.9% increase over the fourth quarter of 2005.  Our average 
number of worksite employees paid for the full year increased 13.4% over 2005.  These increases were driven by 
improvements in sales and the net change in existing clients.  

Our 2006 average gross profit per worksite employee per month of  $234 reflected the effective execution 

of our pricing strategy, including a slight increase in the markup related to our HR services, while managing our 
direct costs to better than expected levels.  Lower than expected direct costs, particularly benefits costs and workers’ 
compensation costs, were primarily a result of the favorable trends in claims experience, complemented by lower 
administrative fees negotiated with our insurance carriers.  Benefits costs per participant increased 5.7% over 2005, 
while workers’ compensation costs as a percentage of non-bonus payroll declined by 15.6%. 

Operating expenses increased by 15.2% in 2006 to $221.2 million on a 13.4% increase in the number of 

worksite employees paid.  Operating expenses increased due primarily to investments in sales and service personnel 
for the current and future growth of our business.  On a per worksite employee per month basis, operating expenses 
increased from $180 in 2005 to $183 in 2006. 

Our net income increased 55.1% to $46.5 million in 2006 over 2005.  We ended 2006 with working capital 

of $128.4 million, which is a $35.2 million increase from the end of 2005. 

Revenues 

We account for our revenues in accordance with Emerging Issues Task Force (“EITF”) 99-19, Reporting 

Revenues Gross as a Principal Versus Net as an Agent.  Our 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 

- 22 - 

 
 
 
 
 
 
  
 
 
 
 
 
 
 
 
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 
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 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 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 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.  In 2005, the non-cash expenses 
associated with the acceleration of stock option vesting were also included.

•  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;  
administrative costs, such as postage, printing and supplies;  
employee travel expenses; and 
repairs and maintenance costs associated with our facilities and technology infrastructure. 

•  Commissions – Commission expense consists of amounts paid to sales personnel.  Commissions for sales 

personnel are based on 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 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, state unemployment and payroll 
taxes, 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”), Cigna Healthcare, PacifiCare, Kaiser Permanente, 
Blue Cross and Blue Shield of Georgia, Blue Shield of California, Hawaii Medical Service Association and 
Tufts, all of which provide fully insured policies or service contracts.  

The policy with United, which was first obtained in January 2002, 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) recent claim development patterns under the plan, to 
estimate a completion rate; and (iii) the number of participants in the plan.  Each reporting period, changes in  
- 24 - 

 
 
 
 
 
 
 
 
 
 
 
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 in January 2002, 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 cash funded 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 cash funded 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 
require us to maintain an accumulated cash surplus in the plan of $11 million, which is reported as long-term 
prepaid insurance.  As of December 31, 2006, Plan Costs were less than the net cash funded to United by $15.3 
million.  As this amount is in excess of the agreed-upon $11 million surplus maintenance level, the $4.3 million 
balance is included in prepaid insurance, a current asset, 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 a decrease (or increase) in benefits costs and net income would increase (or decrease) 
accordingly.   

The following table illustrates the sensitivity of changes in the completion rates on our estimate of total 
benefit costs of $547.4 million in 2006:

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 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 December 2001, as a result of a 2001 corporate reorganization, we filed for a transfer of our reserve account 
with the Employment Development Department of the State of California (“EDD”).  The EDD approved our 
request for transfer of our reserve account in May 2002, and notified us of our new contribution rates based 
upon the approved transfer.  In December 2003, we 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 
Administaff’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 our California employees for 2003, 
resulting in an assessment of $5.6 million.  In January 2004, we filed a petition with an administrative law judge 
of the California Unemployment Insurance Appeals Board (“ALJ”) to protest the validity of the Notice.  
Pending a resolution of our protest, in the fourth quarter of 2003 we accrued and recorded at the higher assessed 
rate for all of 2003.   

In June 2004, we agreed to settle our dispute with the EDD for $3.3 million (“Settlement”).  Based upon receipt 
of written acknowledgement of this agreement, we reduced our accrued payroll tax liability and payroll tax 
expense by $2.3 million during the quarter ended June 30, 2004.  The Settlement was subject to the final 
approval by EDD’s legal department, the California Attorney General’s office and the ALJ.  In October 2004, 
the legal department of the EDD verbally indicated they considered the previously agreed-upon settlement 
amount to be insufficient and suggested a settlement amount of $5.2 million.  We continued discussions with the 

- 25 - 

 
 
 
 
 
 
 
 
 
 
 
 
 
 
State of California, but in February 2005, we were notified that the EDD had rejected our settlement offer and 
the matter proceeded with the appeals process with the ALJ.  As of October 31, 2006, all of the statutes of 
limitations concerning notices to modify unemployment tax rates for the periods addressed in the Notice had 
expired.  We believe the EDD failed to meet the statutory requirement related to serving a proper notice within 
the stipulated time frame; therefore, we believe it is no longer probable that the amount accrued for the 
California unemployment tax matter will be incurred.  Accordingly, we reduced the state unemployment tax 
accrual by $3.3 million during 2006.  

•  Workers’ compensation costs – Our workers’ compensation coverage (the “AIG Program”) is currently provided 
through selected member insurance companies of American International Group, Inc. (“AIG”).  Under our 
arrangement with AIG, we bear the economic burden for the first $1 million layer of claims per occurrence.  
AIG bears the economic burden for all claims in excess of such first $1 million layer.  The AIG Program is a 
fully insured policy whereby AIG has the responsibility to pay all claims incurred under the policy regardless of 
whether we satisfy our responsibilities.  

Because we bear the economic burden of the first $1 million layer of claims per occurrence, 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.  Our management estimates our workers’ compensation costs by applying an 
aggregate loss development rate to worksite employee payroll levels.   

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, 2006 
and 2005, Administaff reduced accrued workers’ compensation costs by $6.4 million and $4.6 million, 
respectively, for changes in estimated losses and tax surcharges 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 rate utilized in 2006 
and 2005 was 4.8% and 3.9%, 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 $55.7 million in 2006:

At the beginning of each policy period, the insurance carrier, AIG, establishes monthly funding requirements 
comprised of premium costs and funds to be set aside for payment of future claims (“claim funds”).  The level of 

- 26 - 

 
 
 
 
 
 
 
 
 
 
 
 
 
 
claim funds is primarily based upon anticipated worksite employee payroll levels and expected workers’ 
compensation loss rates, as determined by AIG.  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.   

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. 

As of December 31, 2006, we had restricted cash of $37.4 million and deposits of $46.4 million.  We have 
estimated and accrued $77.4 million in incurred workers’ compensation claim costs as of December 31, 2006. 

•  Contingent liabilities – We accrue and disclose contingent liabilities in our Consolidated Financial Statements in 

accordance with Statement of Financial Accounting Standards (“SFAS”) No. 5, Accounting for Contingencies.  
SFAS No. 5 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. We have 
disclosed in our audited financial statements several issues that we believe are reasonably possible to occur, 
although we cannot determine the range of possible loss in all cases.  See Note 12 to our Consolidated Financial 
Statements.  As these issues develop, we will continue to 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 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 Client Service Agreement 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 condition 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.  

- 27 - 

 
 
 
 
 
 
 
 
 
•  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 in accordance with SFAS No. 144, Accounting for 
Impairment or Disposal of Long-Lived Assets.  If events or circumstances were to indicate that any of our long-
lived assets might be impaired, we would analyze the estimated undiscounted future cash flows to be generated 
from the applicable asset.  In addition, we would 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 

–
 The December 2005 acquisition of HRTools.com and associated software 
applications included certain identifiable intangible assets and goodwill implied in the purchase price.  The 
goodwill and intangible assets are subject to the provisions of SFAS No. 142, “Goodwill and Other Intangible 
Assets” (“SFAS 142”).  In accordance with SFAS 142, goodwill is tested for impairment on an annual basis and 
between annual tests in certain circumstances, and written down when impaired. Furthermore, SFAS 142 
requires purchased intangible assets other than goodwill to be 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  

In July 2006, the Financial Accounting Standards Board (“FASB”) issued FASB Interpretation No. 48, 

“Accounting for Uncertainty in Income Taxes” (“FIN 48”), an interpretation of FASB Statement No. 109, 
“Accounting for Income Taxes.”  FIN 48 requires that a position taken or expected to be taken in a tax return be 
recognized in the financial statements when it is more likely than not (i.e. a likelihood of more than fifty percent) that 
the position would be sustained upon examination by tax authorities. A recognized tax position is then measured at 
the largest amount of benefit that is greater than fifty percent likely of being realized upon ultimate settlement. The 
effective date for the Company is January 1, 2007.  Upon adoption, the cumulative effect of applying the recognition 
and measurement provisions of FIN 48, if any, shall be reflected as an adjustment to the opening balance of retained 
earnings.  The adoption of FIN 48 is not anticipated to have a material impact on our Consolidated Financial 
Statements.  

In September 2006, FASB Statement 157, “Fair Value Measurements” (“SFAS 157”) was issued.  SFAS 

157 establishes a framework for measuring fair value by providing a standard definition of fair value as it applies to 
assets and liabilities.  SFAS 157, which does not require any new fair value measurements, clarifies the application 
of other accounting pronouncements that require or permit fair value measurements.  The effective date for the 
Company is January 1, 2008.  The Company is evaluating the impact of adopting SFAS 157 on its Consolidated 
Financial Statements.

Revenues 

Our revenues, which represent gross billings net of worksite employee payroll cost, increased 18.8% over 

2005 due to a 13.4% increase in the average number of worksite employees paid per month and a 4.7%, or $52, 
increase in revenues per worksite employee per month.  The 4.7% increase in revenues per worksite employee per 
month was due to both: (i) increases in the pricing components related to our direct costs, including payroll taxes, 
benefits and workers’ compensation costs; and (ii) an increase in the markup related to our HR services.   

By region, our revenue growth over 2005 and revenue distribution for years ended December 31, 2006 and

Our unit growth rate 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 2006, the 13.4% increase in the 
average number of worksite employees paid per month resulted from improvements in new client sales and the net 
change in existing clients, while client retention, measured as a percentage of the worksite employee base, declined 
as compared to 2005. 

Gross Profit  

Gross profit increased 19.9% to $282.7 million compared to 2005.  The average gross profit per worksite 

employee increased 5.9% to $234 per month in 2006 versus $221 in 2005.  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 4.7%, our direct costs, which primarily 

include payroll taxes, benefits and workers’ compensation expenses, increased 4.4% to $916 per worksite employee 
per month in 2006 versus $877 in 2005.  The primary direct cost components changed as follows: 

•  Payroll tax costs – Payroll taxes increased $18 per worksite employee per month compared to 2005, due to a 

7.6% increase in average payroll cost per worksite employee per month.  Payroll taxes as a percentage of payroll 
cost decreased from 7.46% in 2005 to 7.27% in 2006.  The 2006 amount includes a $3.3 million payroll tax 
reduction, or 0.05% as a percentage of payroll costs, related to the California state unemployment tax matter. 
Please read “Critical Accounting Policies and Estimates – State Unemployment Taxes” on page 25 for a 
discussion of our accounting for state unemployment taxes. 

•  Benefits costs – The cost of group health insurance and related employee benefits increased $26 per worksite 

employee per month to $453 compared to 2005.  This increase is due to a 5.7% increase in the cost per covered 
employee and a slight increase in the percentage of worksite employees covered under our health insurance plan 
to 72.7% in 2005 versus 72.4% in 2005.  Please read “—Critical Accounting Policies and Estimates – Benefits 
Costs” on page 24 for a discussion of our accounting for health insurance costs.   

•  Workers’ compensation costs – Workers’ compensation costs decreased $5 per worksite employee per month 

compared to 2005.  As a percentage of non-bonus payroll cost, workers’ compensation costs decreased to 0.92% 
in 2006 from 1.09% in 2005, primarily as a result of favorable trends in both the frequency and severity of 
workers’ compensation claims.  During 2006, the Company recorded reductions in workers’ compensation costs 
of $6.4 million, or 0.11% of non-bonus payroll costs, for changes in estimated losses and tax surcharges, 
compared to $4.6 million, or 0.09% of non-bonus payroll costs in 2005.  Please read “Critical Accounting 
Policies and Estimates – Workers’ Compensation Costs” on page 26 for a discussion of our accounting for 
workers’ compensation costs.

Operating expenses increased 15.2% to $221.2 million.  Operating expenses per worksite employee per 
month increased 1.7% to $183 in 2006 versus $180 in 2005.  The components of operating expenses changed as 
follows: 

•  Salaries, wages and payroll taxes of corporate and sales staff increased 20.5%, or $6 per worksite employee per 
month compared to 2005.  During 2006, the number of corporate employees increased 16.6%, and the average 
pay for corporate employees increased 4.2% as compared to 2005. 

•  Stock-based compensation increased 64.1%, or $1 per worksite employee per month.  Stock-based 

compensation expense primarily represents the vesting of restricted stock awards.  The 2006 expense also 
includes $280,000 related to the annual stock grant made to the independent members of the Board of Directors. 
The 2005 amount includes $790,000 related to the acceleration of stock option vesting.  Please read Note 1 to 
the Consolidated Financial Statements on page F-17 for additional information.  

•  General and administrative expenses increased 8.4% due primarily to higher expenses associated with the 
increase in corporate and worksite employee headcount, such as travel, postage and rent.  General and 
administrative expenses decreased $2 per worksite employee per month compared to 2005.  

•  Commissions expense increased 8.4%, but declined $1 per worksite employee per month compared to 2005. 

•  Advertising costs increased 15.5%, due primarily to increases in radio and television advertising associated with 
the 2006 sales campaigns.  These costs remained flat on a per worksite employee basis as compared to 2005. 

•  Depreciation and amortization expense increased 1.8%, but declined $1 on a per worksite employee basis versus 

2005.   

Other Income (Expense)  

Other income (expense) increased to $10.5 million in 2006 compared to $4.0 million in 2005.  Interest 

income increased by $4.8 million, primarily as a result of an increase in cash balances, including cash held in our 
workers ’ compensation program, and higher interest rates in 2006.  Interest expense decreased $1.2 million as 
compared to 2005, due to the repayment of the $32.3 million outstanding variable-rate mortgage on our corporate 
headquarters in May 2006.

Income Tax Expense 

During 2006 we incurred federal and state income tax expense of $25.6 million on pre-tax income of $72.1 

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 by tax-exempt interest income.  Our effective income tax rate was 35.5% 
in the 2006 period compared to 37.2% in the 2005 period.   

Net Income 

Net income for 2006 was $46.5 million, or $1.64 per diluted share, compared to $30.0 million, or $1.12 per 

diluted share in 2005.  On a per worksite employee per month basis, net income increased 35.7% to $38 in 2006 
versus $28 in 2005.

Revenues 

Our revenues, which represent gross billings net of worksite employee payroll cost, increased 20.6% over 

2004 due to a 13.9% increase in the average number of worksite employees paid per month and a 5.9%, or $61, 
increase in revenues per worksite employee per month.  The 5.9% increase in revenues per worksite employee per 
month was due to both: (i) increases in the pricing components related to our direct costs, including payroll taxes, 
benefits and workers’ compensation costs; and (ii) an increase in the markup related to our HR services.   

Our unit growth rate 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.  The 13.9% increase in the average

Gross Profit  

Gross profit increased 19.3% to $235.8 million compared to 2004.  Gross profit per worksite employee 

increased 4.7% to $221 per month in 2005 versus $211 in 2004.   

While our revenues per worksite employee per month increased 5.9%, our direct costs, which primarily 

include payroll taxes, benefits and workers’ compensation expenses, increased 6.2% to $877 per worksite employee 
per month in 2005 versus $826 in 2004.  The primary direct cost components changed as follows: 

•  Payroll tax costs – Payroll taxes increased $34 per worksite employee per month.  Payroll taxes as a percentage 
of payroll cost were 7.46% in 2005.  This compares to 7.41% in 2004 which included a $2.3 million payroll tax 
credit, or 0.05% as a percentage of payroll costs, related to a state unemployment matter with the state of 
California.  Please read “Critical Accounting Policies and Estimates – State Unemployment Taxes” on page 25 
for a discussion of our accounting for state unemployment taxes. 

•  Benefits costs – The cost of health insurance and related employee benefits increased $23 per worksite employee 
per month to $427 compared to 2004.  This increase is due to a 3.9% increase in the cost per covered employee 
and an increase in the percentage of worksite employees covered under our health insurance plan to 72.4% in 
2005 versus 71.1% in 2004.  Please read “—Critical Accounting Policies and Estimates – Benefits Costs” on 
page 24 for a discussion of our accounting for health insurance costs.   

•  Workers’ compensation costs – Workers’ compensation costs decreased $7 per worksite employee per month 

compared to 2004.  As a percentage of non-bonus payroll cost, workers’ compensation costs decreased to 1.09% 
in 2005 from 1.35% in 2004, primarily as a result of favorable trends in both the frequency and severity of 
workers’ compensation claims.  These trends resulted in reductions in estimated accrued workers’ compensation 
costs related to prior reporting periods of $4.6 million, or 0.09% of non-bonus payroll costs, in the 2005 period. 
 Please read “Critical Accounting Policies and Estimates – Workers’ Compensation Costs” on page 26 for a 
discussion of our accounting for workers’ compensation costs.

Operating expenses increased 9.4% to $192.0 million.  Operating expenses per worksite employee per 

month decreased 4.3% to $180 in 2005 versus $188 in 2004.  The components of operating expenses changed as 
follows: 

•  Salaries, wages and payroll taxes of corporate and sales staff increased 12.8%, but declined $1 per worksite 

employee per month compared to 2004.  During 2005, incentive compensation increased $6.1 million over 2004 
due to the improved operating results.  In addition, the number of corporate employees increased 3.1%, and the 
average pay for corporate employees increased 3.4%. 

•  Stock-based compensation expense of $2.1 million or $2 per worksite employee per month was a result of: (i) 

$790,000 related to the acceleration of stock option vesting during the first quarter of 2005; and (ii) $1,289,000 
related to the amortization of deferred compensation expense associated with the February 2005 restricted stock 
grant.  Please read Note 1 to the Consolidated Financial Statements on page F-17 for additional information. 

•  General and administrative expenses increased 7.5%, but declined $3 per worksite employee per month 

compared to 2004.  The increase in total dollars is primarily due to increases in: (i) repairs and maintenance; and 
(ii) professional fees such as consulting fees, accounting fees and recruiting costs. 

•  Commissions expense decreased 3.1% or $1 per worksite employee per month compared to 2004, as an increase 
in commissions paid to sales personnel was more than offset by cost savings resulting from the termination of 
our marketing and commission arrangement with American Express in December 2004.  

•  Advertising costs increased 20.7%, due primarily to increases in radio and television advertising associated with 
the 2005 sales campaigns.  These costs remained flat on a  per worksite employee basis as compared to 2004. 

•  Depreciation and amortization expense decreased 13.4% and $5 on a per worksite employee basis versus 2004 
as the effect of certain fixed assets becoming fully amortized more than offset the incremental depreciation and 
amortization expense related to the 2005 capital additions.   

Other Income (Expense)  

Other income (expense) decreased to $4.0 million in 2005 compared to $8.6 million in 2004, primarily due 
to the $8.25 million settlement of our dispute with Aetna during the 2004 period.  Interest income increased by $4.1 
million, primarily as a result of an increase in cash balances, including cash held in our workers ’ compensation 
program and higher interest rates in 2005.

Income Tax Expense 

During 2005, we incurred federal and state income tax expense of $17.8 million on pre-tax income of $47.7 

million.  Our provision for income taxes differed from the US statutory rate of 35% primarily due to state income 
taxes and non-deductible expenses.  Our effective income tax rate was 37.2% in the 2005 period compared to 37.5% 
in the 2004 period.   

Net Income 

Net income for 2005 was $30.0 million, or $1.12 per diluted share, compared to $19.2 million, or $0.72 per 

diluted share in 2004.  Net income for 2004 included $5.2 million or $0.19 per share of proceeds related to the 
settlement of our dispute with Aetna.  On a per worksite employee per month basis, net income increased 33.3% to 
$28 in 2005 versus $21 in 2004. 

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 generally accepted accounting principles (“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, debt service requirements and other operating cash needs.  To meet  short- 
and long-term liquidity requirements, including payment of direct and operating expenses and repaying debt, we rely 
primarily on cash from operations.  However, 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 $234.0 
million in cash and cash equivalents and marketable securities at December 31, 2006, of which approximately 
$105.3 million was payable in early January 2007 for withheld federal and state income taxes, employment taxes and 
other  payroll deductions.  At December 31, 2006, we had working capital of $128.4 million compared to $93.2 
million at December 31, 2005.  We currently believe that our cash on hand, marketable securities and cash flows

from operations will be adequate to meet our liquidity requirements for 2007.  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 2006 of $88.5 million reflected a decrease of $23.2 million from 

2005.  Our primary source of cash from operations is the comprehensive service fee and payroll funding we collect 
from our 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 customer 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; 
therefore, operating cash flows decline in the reporting periods that end on a Friday, such as December 
2006, when client prepayments were $9.1 million and accrued worksite employee payroll was $94.8 
million. However, for those reporting periods that end on a Thursday, our cash flows are higher due to the 
collection of the comprehensive service fee and client’s payroll funding prior to processing the large 
number worksite employees’ payrolls one day subsequent to the period end. 

Classification of tax benefit from stock based compensation – In 2006, we adopted Statement 123(R), 
which requires all share-based payments to employees to be recognized as a compensation cost.  In 
addition, Statement 123(R) requires the tax benefit associated with stock based-compensation to be reported 
as a financing activity in the Consolidated Statement of Cash Flows.  Prior to 2006, we reported the tax 
benefit as a component of operating cash flows, which was $12.8 million in 2005. 

Operating results – Our net income has a significant impact on our operating cash flows.  Our net income 
increased to $46.5 million in 2006 from $30.0 million in 2005.  Please read “Results of Operations – Year 
Ended December 31, 2006 Compared to Year Ended December 31, 2005” on page 29.     

Medical plan funding – Our healthcare 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 in 
January 2002, cash funded to United has exceeded Plan Costs, resulting in a $15.3 million surplus, $4.3 
million of which is reflected as a current asset, and $11.0 million of which is reflected as a long-term asset 
on our Consolidated Balance Sheets at December 31, 2006.  Additionally, the $17.5 million in long-term 
deposits was returned to Administaff during 2005. 

Workers’ compensation plan funding – Under our arrangement with AIG, we make monthly payments to 
AIG 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 agreement with AIG, and are based primarily on 
anticipated worksite employee payroll levels and workers compensation loss rates during the policy year.  
Changes in payroll levels from that which was anticipated in the arrangement with AIG can result in 
changes in the amount of the cash payments to AIG, which will impact our reporting of operating cash 
flows.  Our claim funds paid to AIG, based upon anticipated worksite employee payroll levels and workers’ 
compensation loss rates, were $47.4 million, less claims paid of $20.7 million in 2006, and $50.0 million, 
less claims paid of $17.2 million for the 2005 period.  This compares to our estimate of workers’ 
compensation loss costs of $37.8 million and $36.0 million in 2006 and 2005, respectively.  Additionally, 
during the years ended December 31, 2006 and 2005, AIG returned $29.7 million and $22.8 million, 
respectively, to Administaff for the return of excess funding related to prior policy periods.

Cash Flows From Investing Activities 

Our cash flows used in investing activities of $40.4 million reflected a decrease of $25.1 million from 2005. 
 During 2006, we invested $27.6 million in marketable securities and $12.9 million in capital expenditures, primarily 
computer hardware and software to enhance the performance and stability of our technology infrastructure.   

We expect approximately $15 million in capital expenditures in 2007. 

Cash Flows Used In Financing Activities 

Cash flows used in financing activities were $37.1 million during 2006, an increase of $46.5 million over 

2005.  In May 2006, we paid the remaining balance of $32.3 million on our variable-rate mortgage prior to its 
maturity date of January 2008.  Please read Note 6 to the Consolidated Financial Statements on page F-22 for 
additional information.  

Additionally, we repurchased $24.2 million in treasury stock and paid $10.0 million in dividends, offset by 

the receipt of $16.8 million in stock option exercise proceeds and $12.7 million in income tax benefit from stock-
based compensation.

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.

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

Liability for Worksite Employee Payroll and Benefits Costs 

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; 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 

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

primary health insurance contract expires on December 31, 2007, and automatically renews each year, subject to 
cancellation by either party upon 180 days notice. 

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.  
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 24. 

Increases in Workers’ Compensation Costs 

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 bankruptcy or a 
similar proceeding, most states have established guaranty funds to pay remaining claims.  However, the guarantee 
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 National Indemnity 
Co., declared bankruptcy 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, 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 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.  

The current workers’ compensation contract with AIG expires on September 30, 2007.  In the event we are 

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

- 38 - 

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
Our workers’ compensation coverage (the “AIG Program”) is currently provided through selected member 
insurance companies of American International Group, Inc. (“AIG”).  Under our arrangement with AIG, we bear the 
economic burden for the first $1 million layer of claims per occurrence.  AIG bears the economic burden for all 
claims in excess of such first $1 million layer.  The AIG Program is a fully insured policy whereby AIG 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 AIG, 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 26. 

In conjunction with entering into the AIG Program, 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.   

Increases in Unemployment Tax Rates 

We record our state unemployment 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.  Should our claim experience increase, our unemployment tax rates could increase.  In 
addition, states have the ability under law to increase unemployment tax rates to cover deficiencies in the 
unemployment tax fund.  Some states have implemented retroactive cost increases.  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 state unemployment taxes, please 
read Item 7. “Management’s Discussion and Analysis of Financial Condition and Results of Operations – Critical 
Accounting Policies and Estimates – State Unemployment Taxes” on page 25. 

Need to Renew or Replace Clients 

Our standard CSA can be cancelled by us or the client with 30 to 60 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 2006.  There can be no assurance that the number of contract cancellations 
will continue at these levels or increase in the future. 

Competition and New Market Entrants 

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.  We also encounter 
competition from “fee for service” companies such as payroll processing firms, insurance companies and human 
resource consultants.  Several of our competitors are PEO divisions of large business services companies, such as 
Automatic Data Processing, Inc. and Paychex, Inc.  Such companies have substantially greater resources than 
Administaff.  Accordingly, the PEO divisions of such companies 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 us may 
enter the PEO market, possibly including large “fee for service” companies currently providing a more limited range 
of services. 

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 

- 39 - 

 
 
 
  
 
 
 
 
 
 
 
 
 
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.  However, because we act as a co-employer, we may be subject to liability for violations 
of these or other 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 liabilities. 
 In addition, worksite employees may be deemed to be our agents, which may subject us to liability for the actions of 
such worksite employees.  

We maintain certain general insurance coverages (including coverages for our clients) to manage our 
exposure for these types of 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. 

Federal, State and Local Regulation 

As a major employer, our operations are affected by numerous federal, state and local laws and regulations 
relating to labor, tax 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 these other federal or state laws to the PEO relationship with our worksite employees 
could have a material adverse effect on our results of operations or financial condition. 

While many states do not explicitly regulate PEOs, 31 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 

While we have sales offices in 22 markets, our Houston and Texas (including Houston) markets accounted 
for approximately 19% and 36%, respectively, of our revenues for the year ended December 31, 2006.  Accordingly, 
while we have a goal of expanding in our current and future markets outside of Texas, for the foreseeable future, a 
significant portion of our revenues may be subject to economic factors specific to Texas (including Houston).   

Potential Client Liability for Employment Taxes 

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 
- 40 - 

 
 
 
 
 
 
 
 
 
 
 
 
 
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. 

ITEM 7A.  QUALITATIVE AND QUANTITATIVE 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 marketable securities are currently managed by two professional investment management companies, 
each of which is guided by our investment policy.  Our investment policy is designed to maximize after-tax interest 
income while preserving our principal investment.  As a result, our marketable securities consist primarily of tax-
exempt short and intermediate-term debt securities. 

As of December 31, 2006, our available-for-sale marketable securities included an investment in a mutual 

fund that holds corporate debt securities with maturities up to 18 months.  The amortized cost basis, fair market 
value and 30-day yield of this investment was $11.7 million, $11.5 million and 4.86%, respectively, at December 31, 
2006.  The following table presents information about our available-for-sale marketable securities, excluding the 
mutual fund investment, as of December 31, 2006 (dollars in thousands):

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, 2006. 

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, 2006.  Ernst & Young, LLP, our independent registered public accounting firm, 
also attested to, and reported on, management’s assessment of the effectiveness of internal control over financial 
reporting.  Management’s report and the independent registered public accounting firm’s attestation report are 
included in our 2006 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, 2006 that has materially affected, or is reasonably likely to materially affect, our 
internal controls over financial reporting.

Board of Directors and Stockholders 
Administaff, Inc. 

We have audited the accompanying Consolidated Balance Sheets of Administaff, Inc. as of December 31, 
2006 and 2005, and the related Consolidated Statements of Operations, Stockholders’ Equity and Cash Flows for 
each of the three years in the period ended December 31, 2006.  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 Consolidated Financial Statements referred to above present fairly, in all material 

respects, the consolidated financial position of Administaff, Inc. at December 31, 2006 and 2005, and the 
consolidated results of its operations and its cash flows for each of the three years in the period ended December 31, 
2006, in conformity with United States generally accepted accounting principles. 

We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board 
(United States), the effectiveness of Administaff, Inc.’s internal control over financial reporting as of December 31, 
2006, 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 7, 2007 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, 2006 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, 2006 
have issued an attestation report on management’s assessment 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, 2006, 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 management’s assessment, included in the accompanying Management’s Report on 

Internal Control, that Administaff, Inc. maintained effective internal control over financial reporting as of December 
31, 2006, 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. Our responsibility is to express an opinion on 
management’s assessment and an opinion on the effectiveness of 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, evaluating management’s 
assessment, testing and evaluating the design and operating effectiveness of internal control, 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, management’s assessment that Administaff, Inc. maintained effective internal control over 

financial reporting as of December 31, 2006, is fairly stated, in all material respects, based on the COSO criteria.  
Also, in our opinion, Administaff, Inc. maintained, in all material respects, effective internal control over financial 
reporting as of December 31, 2006, 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, 2006 and 2005, and 
the related Consolidated Statements of Operations, Stockholders’ Equity and Cash Flows for each of the three years 
in the period ended December 31, 2006 of Administaff, Inc. and our report dated February 7, 2007 expressed an 
unqualified opinion thereon.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS 
December 31, 2006 

1.  Accounting Policies 

Description of Business 

Administaff, Inc. (the “Company”) is a professional employer organization (“PEO”).  As a PEO, the 
Company provides a bundled comprehensive service for its clients in the area of personnel management.  The 
Company provides its comprehensive service through its Personnel Management System, which encompasses a 
broad range of human resource functions, including payroll and benefits 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.  

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 2006, 2005 and 2004, revenues from the Company’s Texas 
markets represented 36%, 39% and 39% of the Company’s total revenues, respectively. 

Revenue and Direct Cost Recognition 

The Company accounts for its revenues in accordance with EITF 99-19, Reporting Revenues Gross as a 

Principal Versus Net as an Agent.  The Company’s 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 are

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

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 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 in one reportable segment under the Statement of Financial Accounting Standards 

(“SFAS”) No. 131, Disclosures about Segments of an Enterprise and Related Information. 

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.  

Cash and Cash Equivalents 

Cash and cash equivalents include bank deposits and short-term investments with original maturities of 

three months or less at the date of purchase. 

Marketable Securities 

The Company accounts for marketable securities in accordance with SFAS No. 115, Accounting for Certain 
Investments in 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, 2006 and 2005, 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 

F-13

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (Continued) 

deduction from the coupon interest earned on the investments.  The Company follows its investment managers’ 
methods of determining the cost basis in computing realized gains and losses on the sale of its available-for-sale 
securities, which includes both the specific identification and average cost methods.  Realized gains and losses are 
included in other income (expense). 

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 
1-7 years 
Computer hardware and software ..................................................................  
3-5 years 
Software development costs...........................................................................  
5-7 years 
Furniture and fixtures.....................................................................................  
20 years 
Aircraft...........................................................................................................  
5 years 
Vehicles .........................................................................................................  

Software development costs relate primarily to the Company’s proprietary professional employer 
information system and its Internet-based service delivery platform, the Employee Service Center, and are accounted 
for in accordance with Statement of Position (“SOP”) 98-1, Accounting for the Costs of Computer Software 
Developed or Obtained for Internal Use. 

The Company periodically evaluates its long-lived assets for impairment in accordance with SFAS No. 144, 
Accounting for the Impairment or Disposal of Long-Lived Assets.  SFAS No. 144 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 analyze the estimated undiscounted future cash flows to be generated from the 
applicable asset.  In addition, the Company would 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.  As of December 31, 2006, the 
Company had no impairments. 

Goodwill and Other Intangible Assets 

The December 2005 acquisition of HRTools.com and associated software applications included certain 

identifiable intangible assets and goodwill in the purchase price.  The goodwill and intangible assets are subject to 
the provisions of SFAS No. 142, “Goodwill and Other Intangible Assets” (“SFAS 142”).  In accordance with SFAS 
142, goodwill and other intangible assets are tested for impairment on an annual basis or when indicators of 
impairment exist, and written down when impaired. As of December 31, 2006, no impairment write downs were 
necessary.  Furthermore, SFAS 142 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 Company’s estimated amortization expense related to purchased intangible 
assets other than goodwill is $420,000 per year during 2007 through 2010 and $131,000 in 2011.

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

Health Insurance Costs 

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

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

The policy with United, which was first obtained in January 2002, 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 the quarter; (ii) recent claim development patterns under the plan, to 
estimate a completion rate; and (iii) the number of participants in the plan.  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 in January 2002, 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 cash funded 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 cash funded 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 require 
us to maintain an accumulated cash surplus in the plan of $11 million, which is reported as long-term prepaid 
insurance.  As of December 31, 2006, Plan Costs were less than the net cash funded to United by $15.3 million.  As 
this amount is in excess of the agreed-upon $11 million surplus maintenance level, the $4.3 million balance is 
included in prepaid insurance, a current asset, on our Consolidated Balance Sheet.  

Workers’ Compensation Costs 

Our workers’ compensation coverage (the “AIG Program”) is currently provided through selected member 
insurance companies of American International Group, Inc. (“AIG”).  Under our arrangement with AIG, we bear the 
economic burden for the first $1 million layer of claims per occurrence.  AIG bears the economic burden for all 
claims in excess of such first $1 million layer.  The AIG Program is a fully insured policy whereby AIG has the 
responsibility to pay all claims incurred under the policy regardless of whether we satisfy our responsibilities.  

Because the Company bears the economic burden of the first $1 million layer of claims per occurrence, 

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 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.  The Company estimates its workers’ compensation costs by 
applying an aggregate loss development rate to worksite employee payroll levels.

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

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 $6.4 million in 2006 and $4.6 million in 2005 for 
changes in estimated losses and tax surcharges 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 rate utilized in 2006 and 2005 was 4.8% and 
3.9%, 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 following table provides the activity and balances related to incurred but not reported workers’ 

compensation claims for the years ended December 31, 2006 and 2005 (in thousands):

At the beginning of each policy period, the insurance carrier, AIG, 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 AIG.  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.   

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. 

As of December 31, 2006, the Company had restricted cash of $37.4 million and deposits of $46.4 million. 

The Company has estimated and accrued $77.4 million in incurred workers’ compensation claim costs as of 
December 31, 2006.

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 and long-term debt and capital leases approximate fair value due to the stated interest rates 
approximating market rates. 

Stock-Based Compensation 

At December 31, 2006, the Company has three stock-based employee compensation plans.  Prior to January 

1, 2006, the Company accounted for these plans under the recognition and measurement principles of Accounting 
Principles Board Opinion No. 25, Accounting for Stock Issued to Employees, and related interpretations.  Effective 
January 1, 2006, the Company began accounting for these plans under the recognition and measurement principles of 
Financial Accounting Standards Board (FASB) Statement No. 123 (revised 2004), Share-Based Payment 
(“Statement 123(R)”).  Statement 123(R) 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.  Pro forma disclosure is 
no longer an alternative.  The Company adopted Statement 123(R) using the “modified prospective” method in 
which compensation cost is recognized beginning with the effective date: (a) based on the requirements of Statement 
123(R) for all share-based payments granted after the effective date; and (b) based on the requirements of Statement 
123 for all awards granted to employees prior to the effective date of Statement 123(R) that remain unvested on the 
effective date.   

During the first quarter of 2005, the Company accelerated the vesting of all outstanding stock options, 

resulting in the recognition of $790,000 ($497,000, net of taxes) of stock-based compensation expense.  Because the 
Company accelerated the vesting of all outstanding stock options during the first quarter of 2005, the adoption of 
SFAS 123(R) did not have a material impact on our results of operations in 2006.  The cumulative effect of the 
change in accounting principle associated with the adoption of Statement 123(R) resulted in a $50,000 reduction in 
stock-based compensation and the reclassification of $2.9 million in previously recognized deferred compensation to 
additional paid-in capital and treasury stock.  In accordance with Statement 123(R), the Company has presented its 
income tax benefit from stock-based compensation as a financing activity in the Consolidated Statement of Cash 
Flows, beginning with the 2006 amount of $12.7 million. 

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.  At December 31, 2006 and 2005, the 
Company recognized $3.4 million ($2.2 million net of taxes), and $1.3 million ($810,000 net of taxes), respectively, 
of stock-based compensation expense associated with the stock grants.  As of December 31, 2006, unrecognized 
compensation expense associated with the non-vested shares outstanding was $8.3 million and is expected to be 
recognized over a weighted average period of twenty-seven months.

The fair value for these options was estimated at the date of grant using a Black-Scholes option pricing 
model.  The Black-Scholes option valuation model was developed for use in estimating the fair value of traded 
options, which have no vesting restrictions and are fully transferable.  In addition, option valuation models require 
the input of highly subjective assumptions, including the expected stock price volatility.  Because the Company’s 
employee stock options have characteristics significantly different from those of traded options, and because changes 
in the subjective input assumptions can materially affect the fair value estimate, in the Company’s opinion, the 
existing models do not necessarily provide a reliable single measure of the fair value of its employee stock options. 

Employee Savings Plan 

The Company matches 50% of an eligible worksite employee’s eligible contributions and 100% of eligible 
corporate employees’ contributions, both up to 6% of the employee’s eligible compensation with immediate vesting. 
During 2006, 2005 and 2004, the Company made employer-matching contributions of $32.8 million, $24.4 million 
and $13.5 million, respectively.  Of these contributions, $29.2 million, $21.4 million and $10.7 million were made 
on behalf of worksite employees.  The remainder represents employer contributions made 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 2006 presentation. 

New Accounting Pronouncements 

In July 2006, the Financial Accounting Standards Board (“FASB”) issued FASB Interpretation No. 48, 

“Accounting for Uncertainty in Income Taxes” (“FIN 48”), an interpretation of FASB Statement No. 109, 
“Accounting for Income Taxes.”  FIN 48 requires that a position taken or expected to be taken in a tax return be 
recognized in the financial statements when it is more likely than not (i.e. a likelihood of more than fifty percent) 
that the position would be sustained upon examination by tax authorities. A recognized tax position is then measured 
at the largest amount of benefit that is greater than fifty percent likely of being realized upon ultimate settlement. 
The effective date for the Company is January 1, 2007.  Upon adoption, the cumulative effect of applying the 
recognition and measurement provisions of FIN 48, if any, shall be reflected as an adjustment to the opening balance 
of retained earnings.  The adoption of FIN 48 is not anticipated to have a material impact on our Consolidated 
Financial Statements. 

In September 2006, FASB Statement 157, “Fair Value Measurements” (“SFAS 157”) was issued.  SFAS 

157 establishes a framework for measuring fair value by providing a standard definition of fair value as it applies to 
assets and liabilities.  SFAS 157, which does not require any new fair value measurements, clarifies the application 
of other accounting pronouncements that require or permit fair value measurements.  The effective date for the 
Company is January 1, 2008.  The Company is evaluating the impact of adopting SFAS 157 on its Consolidated 
Financial Statements. 

2.    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 clients, are reported net of allowance 
for doubtful accounts of $863,000 and $582,000 as of December 31, 2006 and 2005, respectively.  The Company 
establishes an allowance for doubtful accounts based on management’s assessment of the collectibility 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 that 
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, 2006 and 2005, 
unbilled accounts receivable consisted of the following:

4.   Deposits 

In 2005, Administaff and United entered into a new three-year arrangement, whereby a previous contractual 

requirement to maintain a security deposit with United was eliminated.  Accordingly, the outstanding security 
deposit of $17.5 million was returned to Administaff during 2005.  The terms of the new arrangement require 
Administaff to maintain an accumulated cash surplus in the plan of $11.0 million, which was the balance of the 
accumulated surplus at December 31, 2004, and is now reported as long-term prepaid health insurance.  

As of December 31, 2006, the Company had $46.4 million of workers’ compensation long-term deposits. 

Please see Note 1 for a discussion of our accounting policies for workers’ compensation costs. 

5.   HRTools.com Acquisition 

In December 2005, the Company acquired certain assets of KnowledgePoint, a subsidiary of Recruitmax, 

for $6.25 million in cash in an effort to extend the Company’s product offering.  The primary assets acquired 
included HRTools.com, a leading portal for human resources products, services and information, as well as small 
business software applications related to job descriptions, performance reviews, and personnel policies and 
procedures.

Mortgage Loan 

In December 2002, the Company entered into a $36 million mortgage agreement (“Mortgage”) with a 
contractual maturing date in January 2008.  The Mortgage had a variable interest rate equal to the greater of (a)

million on the Mortgage. 

Capital Lease Obligations 

In October 2002, the Company entered into a capital lease arrangement to finance the purchase of office 

furniture.  The assets under capital lease were capitalized using an effective interest rate of 7.5%.  The current 
monthly lease payments are $58,000 per month over the seven-year lease term.  As of December 31, 2006 and 2005, 
the capitalized cost and accumulated amortization under the capital lease arrangement were $3.8 million and $2.3 
million, and $3.8 million and $1.8 million, respectively.  Amortization of the capitalized lease costs is included in 
depreciation and amortization in the Consolidated Statements of Operations.

As a result of the write-off of the investments in other companies during 2001 and 2002, the Company has 

capital loss carryforwards totaling $3.1 million that will expire during 2008, but can only be used to offset future 
capital gains.  The Company has a valuation allowance of $3.1 million 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 
valuation allowance was reduced by $2.7 million in 2006 as a result of expired capital loss carryforwards.  In 
addition, the Company has incurred net operating losses at the subsidiary level for state income tax purposes totaling 
$4.0 million ($273,000 tax effected) that expire from 2008 to 2023.  The Company has recorded a valuation 
allowance of $273,000 at December 31, 2006, as it is uncertain if it will be able to utilize the net operating loss 
carryforward in these entities. 

8.  Stockholders’ Equity 

The Company’s Board of Directors (the “Board”) has authorized a program to repurchase up to 8,500,000 

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.  During 
2006, 2005 and 2004, the Company repurchased 614,126, 649,100, and 1,411,000 shares at a cost of $24.2 million, 
$12.2 million and $17.2 million, respectively.  As of December 31, 2006, the Company had repurchased 8,015,749 
shares under this program at a total cost of approximately $119.1 million.  As a result, the Company has the 
authorization to repurchase an additional 484,251 shares. 

During each quarter of 2006 and 2005, the Board declared a dividend of $0.09 and $0.07 per share of 

common stock, resulting in a total of $10.0 million and $7.4 million in dividend payments paid by the Company, 
respectively. 

At December 31, 2006, 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-half of a 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 February 9, 2008.

9.  Employee 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 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 has granted limited authority to the Chief Executive Officer of the 
Company regarding the granting of stock options to employees who are not officers.  The Company 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, 2006, 1,224,977 shares of common stock were available for future grants under the 2001 Incentive Plan.  The 
Incentive Plans permit stock options, primarily 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”) provides for options to 

purchase shares of the Company’s common stock that may be granted to employees who are not officers.  An 
aggregate of 3,600,000 shares of common stock of the Company are authorized to be issued under the Nonqualified 
Plan.  At December 31, 2006, 637,020 shares of common stock were available for future grants under the 
Nonqualified Plan.  The purpose of the Nonqualified Plan is similar to that of the Incentive Plans.  The Nonqualified 
Plan is administered by the Chief Executive Officer of the Company (the “CEO”).  The CEO has the power to 
determine which eligible employees will receive stock option rights, the timing and manner of the grant of such 
rights, the exercise price (which may not be less than market value on the grant date), the number of shares and all of 
the terms of the options.  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. 

Stock Option Awards 

On February 1, 2005, the Committee approved accelerating the vesting of all unvested stock options that 

had an exercise price greater than the Company’s January 31, 2005 closing market price of $14.59.  This accelerated 
vesting affected approximately 733,000 common stock options with a weighted average exercise price of $18.09.  In 
addition, the committee approved accelerating the vesting of all remaining unvested common stock options on 
February 18, 2005.  As a result, the vesting of approximately 1,104,000 common stock options with a weighted 
average exercise price of $9.16 was accelerated, which resulted in the Company recognizing stock-based 
compensation expense of $790,000 in 2005.  The primary purpose of the accelerated vesting was to eliminate future 
compensation expense the Company would otherwise recognize in its income statement with respect to these 
accelerated options subsequent to the January 1, 2006 effective date of FASB Statement No. 123(R).

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 $3.4 million and $1.3 million of compensation expense associated 
with the restricted stock awards in 2006 and 2005, respectively.  As of December 31, 2006, unrecognized compensation 
expense associated with the non-vested shares outstanding was $8.3 million and is expected to be recognized over a 
weighted average period of twenty-seven months.

11.  Leases 

The Company leases various office facilities, furniture, equipment and vehicles under capital and 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 
$9,586,000, $8,847,000 and $9,000,000 in 2006, 2005 and 2004, respectively.  At December 31, 2006, 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. 

Class Action Litigation 

On June 13, 2003, a class action lawsuit was filed against the Company in the United States District Court for the 

Southern District of Texas on behalf of purchasers of the Company’s common stock alleging violations of the federal 
securities laws.  After that date, six similar class actions were filed against the Company in that court.  Those lawsuits 
also named as defendants certain of the Company’s officers and directors.  In May 2004, the lead plaintiff filed its 
Consolidated Complaint, which amended and consolidated the seven previously filed cases.  In June 2004, the Company 
filed a motion to dismiss the Consolidated Complaint.  On March 30, 2006, the court granted the Company’s motion to

dismiss and thereafter entered a final order of dismissal with prejudice.  The lead plaintiff did not file a notice of appeal 
by the deadline to do so.  Accordingly, this matter is now concluded. 

State Unemployment Taxes 

The Company records its 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, the Company estimates its expected 
SUI tax rate in those states for which tax rate notices have not yet been received.   

As a result of a 2001 corporate restructuring, we filed for a transfer of our 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 us of our new contribution rates based upon the approved transfer.  In December 
2003, we 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 our 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 our 
California employees for 2003, resulting in an assessment of $5.6 million.  In January 2004, we filed a petition with an 
administrative law judge of the California Unemployment Insurance Appeals Board (“ALJ”) to protest the validity of the 
Notice.  Pending a resolution of our protest, in the fourth quarter of 2003 we accrued and recorded at the higher assessed 
rate for all of 2003. 

In June 2004, we agreed to settle our dispute with the EDD for $3.3 million.  Based upon receipt of written 
acknowledgement of this agreement, we reduced our accrued payroll tax liability and payroll tax expense by $2.3 million 
during the quarter ended June 30, 2004.  The settlement was subject to the final approval by EDD’s legal department, the 
California Attorney General’s office and the ALJ.  In October 2004, the legal department of the EDD verbally indicated 
they considered the previously agreed-upon settlement amount to be insufficient and suggested a settlement amount of 
$5.2 million.  We continued discussions with the State of California, but in February 2005, we were notified that the 
EDD had rejected our settlement offer, and the matter proceeded with the appeals process with the ALJ.  As of October 
31, 2006, all of the statutes of limitations concerning notices to modify unemployment tax rates for the periods addressed 
in the Notice had expired.  The Company believes the EDD failed to meet the statutory requirement related to serving a 
proper notice within the stipulated time frame; therefore, the Company believes it is no longer probable that the amount 
accrued for the California unemployment tax matter will be incurred.  Accordingly, the Company reduced the state 
unemployment tax accrual by $3.3 million during 2006.

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, 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 period presented. Investors are
encouraged to review the reconciliation of this non-GAAP financial measure used in this report to the most directly
comparable GAAP financial measure as provided in the table above.
