PART I
Item 1. Business
Robert Half International Inc. (the “Company”) provides specialized staffing and risk consulting services through such divisions as Accountemps®, Robert Half® Finance & Accounting, OfficeTeam®, Robert Half® Technology, Robert Half® Management Resources, Robert Half® Legal, The Creative Group®, and Protiviti®. The Company, through its Accountemps, Robert Half Finance & Accounting, and Robert Half Management Resources divisions, is the world’s largest specialized provider of temporary, full-time, and project professionals in the fields of accounting and finance. OfficeTeam specializes in highly skilled temporary administrative support personnel. Robert Half Technology provides information technology professionals. Robert Half Legal provides temporary, project, and full-time staffing of attorneys and specialized support personnel within law firms and corporate legal departments. The Creative Group provides project staffing in the digital, marketing, and creative fields. Protiviti, which began operations in 2002, is a global business consulting and internal audit firm. Protiviti, which primarily employs professionals specializing in risk, advisory and transactional services, is a wholly owned subsidiary of the Company.
The Company’s business was originally founded in 1948. Prior to 1986, the Company was primarily a franchisor, under the names Accountemps and Robert Half (now called Robert Half Finance & Accounting), of offices providing temporary and full-time professionals in the fields of accounting and finance. Beginning in 1986, the Company and its current management embarked on a strategy of acquiring franchised locations. All of the franchises have been acquired. The Company believes that direct ownership of offices allows it to better monitor and protect the image of its tradenames, promotes a more consistent and higher level of quality and service throughout its network of offices and improves profitability by centralizing many of its administrative functions. Since 1986, the Company has significantly expanded operations at many of the acquired locations, opened many new locations and acquired other local or regional providers of specialized temporary service personnel. The Company has also expanded the scope of its services by launching the new product lines OfficeTeam, Robert Half Technology, Robert Half Management Resources, Robert Half Legal and The Creative Group.
In 2002, the Company hired more than 700 professionals who had been affiliated with the internal audit and business and technology risk consulting practice of Arthur Andersen LLP, including more than 50 individuals who had been partners of that firm. These professionals formed the base of the Company’s Protiviti Inc. subsidiary. Protiviti® has enabled the Company to enter the market for business consulting and internal audit services, which market the Company believes offers synergies with its traditional lines of business.
Accountemps
The Accountemps temporary services division offers customers a reliable and economical means of dealing with uneven or peak workloads for accounting, finance, and bookkeeping personnel caused by such predictable events as vacations, taking inventories, tax work, month-end activities and special projects, and such unpredictable events as illness and emergencies. Businesses view the use of temporary employees as a means of controlling personnel costs and converting such costs from fixed to variable. The cost and inconvenience to clients of hiring and firing regular employees are eliminated by the use of Accountemps temporaries. The temporary workers are employees of Accountemps and are paid by Accountemps. The customer pays a fixed rate only for hours worked.
Accountemps clients may fill their regular employment needs by using an Accountemps employee on a trial basis and, if so desired, “converting” the temporary position to a regular position. The client typically pays a one-time fee for such conversions.
OfficeTeam
The Company’s OfficeTeam division, which commenced operations in 1991, places temporary and full-time office and administrative personnel, ranging from executive and administrative assistants to receptionists and customer service representatives. OfficeTeam operates in much the same fashion as the Accountemps division.
Robert Half Finance & Accounting
Established in 1948, the Company’s first division and specialized recruitment pioneer Robert Half Finance & Accounting specializes in the placement of full-time accounting, financial, tax and accounting operations personnel. Fees for successful
1

placements are paid only by the employer and are generally a percentage of the new employee’s annual compensation. No fee for placement services is charged to employment candidates.
Robert Half Technology
The Company’s Robert Half Technology division, which commenced operations in 1994, specializes in providing information technology contract consultants, placing full-time employees, and offering managed services in areas ranging from multiple platform systems integration to end-user technical and desktop support, including specialists in application development (including mobile, cloud and enterprise applications), networking, systems integration and deployment, database design and administration, and security and business continuity.
Robert Half Legal
Since 1992, the Company has been placing temporary and full-time employees in attorney, paralegal, legal administrative and legal secretarial positions through its Robert Half Legal division. The legal profession’s requirements (the need for confidentiality, accuracy and reliability, a strong drive toward cost-effectiveness, and frequent peak caseload periods) are similar to the demands of the clients of the Accountemps division. Robert Half Legal offers a full suite of legal staffing and consulting services to help organizations manage constantly changing workloads and access expertise across in-demand legal practice areas.
Robert Half Management Resources
The Company’s Robert Half Management Resources division, which commenced operations in 1997, specializes in providing senior level project professionals in the accounting and finance fields, including chief financial officers, controllers, senior financial analysts, internal auditors, and business systems analysts for such tasks as financial systems conversions, expansion into new markets, business process reengineering, business systems performance improvement, and post-merger financial consolidation.
The Creative Group
The Creative Group division commenced operations in 1999 and specializes in identifying for its clients creative professionals in the areas of interactive media, design, marketing, advertising and public relations. The division places freelance and project consultants in a variety of positions such as creative directors, graphics designers, web content developers, web designers, media buyers, brand managers, and public relations specialists.
Protiviti
Protiviti is a global consulting firm that helps companies solve problems in finance, technology, operations, data, analytics, governance, risk and internal audit. Through its risk management and internal audit heritage, Protiviti has gained unique perspectives on the challenges faced by its clients. Protiviti uses these perspectives not only to solve regulatory, risk and compliance problems, but also to help clients become more effective and productive. Protiviti provides solutions to its clients in areas such as business performance improvement, internal audit and financial advisory, IT consulting, restructuring and litigation, risk and compliance, and transaction services.
Marketing and Recruiting
The Company markets its staffing services to clients and employment candidates via both national and local advertising activities. Advertising consists of client- and employment candidate-facing buys in radio, outdoor, digital display, search engine marketing, social media, print and trade publications, job boards and events. The Company also markets its services, as well as hiring and career management advice content and thought leadership, via its search engine-optimized website, social media and blog feeds, and e-mail marketing program. Direct marketing via telephone solicitation is a significant portion of the Company’s total marketing efforts. Additionally, the Company has expanded its use of job boards and job aggregators in all aspects of sales and recruitment. Joint marketing arrangements have been entered into with major software manufacturers and typically provide for the development of proprietary skills tests, cooperative advertising, joint e-mail campaigns, and similar promotional activities. The Company also actively seeks endorsements and affiliations with professional organizations in the accounting and finance, technology, legal, and creative and marketing fields. In addition, the Company conducts public relations activities designed to enhance public recognition of the Company and its services. This includes outreach to journalists, bloggers and social media influencers, and the distribution of print, digital, and video thought leadership. Robert Half staffing and recruiting professionals are encouraged to be active in civic organizations and industry trade groups in their local communities.

Protiviti markets its business consulting and internal audit services to a variety of clients in a range of industries. Industry and competency teams conduct targeted marketing efforts, both locally and nationally, including print advertising and branded speaking events, with support from Protiviti management. National advertising conducted by Protiviti consists primarily of print advertisements in national newspapers, magazines and selected trade journals. Protiviti has programs to share its insights with clients on current corporate governance and risk management issues. It conducts public relations activities, such as distributing press releases, white papers, case studies and newsletters, designed to enhance recognition for the Protiviti brand, establish its expertise in key issues surrounding its business and promote its services. Protiviti plans to expand both the services and value added content on the Protiviti.com website and increase traffic through targeted Internet advertising. Local employees are encouraged to be active in relevant social media communities, civic organizations and industry trade groups.
The Company and its subsidiaries own many trademarks, service marks and tradenames, including the Robert Half® Finance & Accounting, Accountemps®, OfficeTeam®, Robert Half® Technology, Robert Half® Management Resources, Robert Half® Legal, The Creative Group® and Protiviti® marks, which are registered in the United States and in a number of foreign countries.
Organization
Management of the Company’s staffing operations is coordinated from its headquarters facilities in Menlo Park and San Ramon, California. The Company’s headquarters provides support and centralized services to its offices in the administrative, marketing, public relations, accounting, training and legal areas, particularly as it relates to the standardization of the operating procedures of its offices. As of December 31, 2017, the Company conducted its staffing services operations through 323 offices in 42 states, the District of Columbia and 17 foreign countries. Office managers are responsible for most activities of their offices, including sales, local advertising and marketing and recruitment.
The day-to-day operations of Protiviti are managed by a chief executive officer and a senior management team with operational and administrative support provided by individuals located in San Ramon and Menlo Park, California. As of December 31, 2017, Protiviti had 56 offices in 23 states and 11 foreign countries.
Competition
The Company’s staffing services face competition in attracting clients as well as skilled specialized employment candidates. The staffing business is highly competitive, with a number of firms offering services similar to those provided by the Company on a national, regional or local basis. In many areas the local companies are the strongest competitors. The most significant competitive factors in the staffing business are price and the reliability of service, both of which are often a function of the availability and quality of personnel. The Company believes it derives a competitive advantage from its long experience with and commitment to the specialized employment market, its national presence, and its various marketing activities.
Protiviti faces competition in its efforts to attract clients and win proposal presentations. The risk consulting and internal audit businesses are highly competitive. In addition, the changing regulatory environment is increasing opportunities for non-attestation audit and risk consulting services. The principal competitors of Protiviti remain the “big four” accounting firms. Significant competitive factors include reputation, technology, tools, project methodologies, price of services and depth of skills of personnel. Protiviti believes its competitive strengths lie in its unique ability to couple the deep skills and proven methodologies of its “big four” heritage with the customer focus and attention of a smaller organization.
Employees
The Company has approximately 17,200 full-time employees, including approximately 3,600 engaged directly in Protiviti operations. In addition, the Company placed approximately 211,400 temporary employees on assignments with clients during 2017. Employees placed by the Company on assignment with clients are the Company’s employees for all purposes while they are working on assignments. The Company pays the related costs of employment, such as workers’ compensation insurance, state and federal unemployment taxes, social security and certain fringe benefits. The Company provides access to voluntary health insurance coverage to interested temporary employees.
Other Information
The Company’s current business constitutes three business segments. (See Note M of Notes to Consolidated Financial Statement in Item 8. Financial Statements and Supplementary Data for financial information about the Company’s segments.)
The Company is not dependent upon a single customer or a limited number of customers. The Company’s staffing services operations are generally more active in the first and fourth quarters of a calendar year. Protiviti is generally more active in the third and fourth quarters of a calendar year. Order backlog is not a material aspect of the Company’s staffing services
3

business. While backlog is of greater importance to Protiviti, the Company does not believe, based upon the length of time of the average Protiviti engagement, that backlog is a material aspect of the Protiviti business. No material portion of the Company’s business is subject to government contracts.
Information about foreign operations is contained in Note M of Notes to Consolidated Financial Statements in Item 8. The Company does not have export sales.

Item 1A. Risk Factors
The Company’s business prospects are subject to various risks and uncertainties that impact its business. The most important of these risks and uncertainties are as follows:
Any reduction in global economic activity may harm the Company’s business and financial condition. The demand for the Company’s services, in particular its staffing services, is highly dependent upon the state of the economy and upon the staffing needs of the Company’s clients. Certain of the Company’s markets have recently experienced prolonged economic downturns characterized by high unemployment, limited availability of credit and decreased consumer and business spending. In addition, certain geopolitical events, including the ongoing negotiation of the United Kingdom’s withdrawal from the European Union (“Brexit”), have caused significant economic, market, political and regulatory uncertainty in some of the Company’s markets. Any decline in the economic condition or employment levels of the U.S. or of any of the foreign countries in which the Company does business, or in the economic condition of any region of any of the foregoing, or in any specific industry may severely reduce the demand for the Company’s services and thereby significantly decrease the Company’s revenues and profits. Further, continued or intensifying economic, political or regulatory uncertainty in the Company’s markets could reduce demand for the Company’s services.
The Company’s business depends on a strong reputation and anything that harms its reputation will likely harm its results. As a provider of temporary and permanent staffing solutions as well as consultant services, the Company’s reputation is dependent upon the performance of the employees it places with its clients and the services rendered by its consultants. The Company depends on its reputation and name recognition to secure engagements and to hire qualified employees and consultants. If the Company’s clients become dissatisfied with the performance of those employees or consultants or if any of those employees or consultants engage in or are believed to have engaged in conduct that is harmful to the Company’s clients, the Company’s ability to maintain or expand its client base may be harmed.
The Company and certain subsidiaries are defendants in several lawsuits that could cause the Company to incur substantial liabilities. The Company and certain subsidiaries are defendants in several actual or asserted class and representative action lawsuits brought by or on behalf of the Company’s current and former employees alleging violations of federal and state law with respect to certain wage and hour related matters, as well as claims challenging the Company’s compliance with the Fair Credit Reporting Act. The various claims made in one or more of such lawsuits include, among other things, the misclassification of certain employees as exempt employees under applicable law, failure to comply with wage statement requirements, failure to compensate certain employees for time spent performing activities related to the interviewing process, and other related wage and hour violations. Such suits seek, as applicable, unspecified amounts for unpaid overtime compensation, penalties, and other damages, as well as attorneys’ fees. It is not possible to predict the outcome of these lawsuits. However, these lawsuits may consume substantial amounts of the Company’s financial and managerial resources and might result in adverse publicity, regardless of the ultimate outcome of the lawsuits. In addition, the Company and its subsidiaries may become subject to similar lawsuits in the same or other jurisdictions, or to various other claims, disputes, and legal or regulatory proceedings that arise in the ordinary course of business. An unfavorable outcome with respect to these lawsuits and any future lawsuits or regulatory proceedings could, individually or in the aggregate, cause the Company to incur
4

substantial liabilities or impact its operations in such a way that may have a material adverse effect upon the Company’s business, financial condition or results of operations. Furthermore, any future lawsuits, claims, disputes, or legal or regulatory proceedings may also consume substantial amounts of the Company’s financial and managerial resources and might result in adverse publicity, regardless of the ultimate outcome. In addition, an unfavorable outcome in one or more of these cases could cause the Company to change its compensation plans for its employees, which could have a material adverse effect upon the Company’s business.
The Company faces risks in operating internationally. The Company depends on operations in international markets, including Europe, for a significant portion of its business. In the past several years, the European market experienced economic uncertainty, which adversely affected, and the return of which may in the future adversely affect, the Company’s operations in Europe. In particular, Brexit has contributed to, and may continue to contribute to, European economic, market and regulatory uncertainty and could adversely affect European or worldwide economic, market, regulatory, or political conditions. To the extent that adverse economic conditions and uncertainty in Europe (related to Brexit or otherwise) worsen, demand for the Company’s services may decline, which could significantly harm its business and results of operations. In addition, these international operations are subject to a number of risks, including general political and economic conditions in those foreign countries, the burden of complying with various foreign laws and technical standards and unpredictable changes in foreign regulations, U.S. legal requirements governing U.S. companies operating in foreign countries, legal and cultural differences in the conduct of business, potential adverse tax consequences and difficulty in staffing and managing international operations. In addition, the Company’s business may be affected by foreign currency exchange fluctuations. In particular, the Company is subject to risk in translating its results in foreign currencies into the U.S. dollar. If the value of the U.S. dollar strengthens relative to other currencies, the Company’s reported income from these operations could decrease. The value of the U.S. dollar has recently strengthened considerably against a number of major foreign currencies, and a continuation or extension of this strength relative to these other currencies could adversely impact the Company’s reported income from its international markets and cause its revenue in such markets, when translated into U.S. dollars, to decline.
The Company could also be exposed to fines and penalties under U.S. or local jurisdiction trade sanctions and controls as well as laws prohibiting corrupt payments to governmental officials. Although the Company has implemented policies and procedures designed to ensure compliance with these laws, it cannot be sure that its employees, contractors or agents will not violate such policies. Any such violations could materially damage the Company’s reputation, brand, business and operating results. Further, changes in U.S. laws and policies governing foreign trade or investment and use of foreign operations or workers, and any negative sentiments towards the United States as a result of such changes, could adversely affect the Company’s operations.
Government regulations may result in prohibition or restriction of certain types of employment services or the imposition of additional licensing or tax requirements that may reduce the Company’s future earnings. In many jurisdictions in which the Company operates, the employment services industry is heavily regulated. For example, governmental regulations in some countries restrict the length of contracts and the industries in which the Company’s employees may be used. In other countries, special taxes, fees or costs are imposed in connection with the use of its employees. Additionally, trade unions in some countries have used the political process to target the industry, in an effort to increase the regulatory burden and expense associated with offering or utilizing temporary staffing solutions.
The countries in which we operate may, among other things:

• | create additional regulations that prohibit or restrict the types of employment services that the Company currently provides;

• | require new or additional benefits be paid to the Company’s employees;

• | require the Company to obtain additional licensing to provide employment services; or

• | increase taxes, such as sales or value-added taxes, payable by the providers of temporary workers.

Any future regulations may have a material adverse effect on the Company’s business and financial results because they may make it more difficult or expensive for the Company to continue to provide employment services. Additionally, as the Company expands existing service offerings, adds new service offerings, or enters new markets, it may become subject to additional restrictions and regulations which may impede its business, increase costs and impact profitability.
The Company may be unable to find sufficient candidates for its staffing business. The Company’s staffing services business consists of the placement of individuals seeking employment. There can be no assurance that candidates for employment will continue to seek employment through the Company. Candidates generally seek temporary or regular positions through multiple sources, including the Company and its competitors. Unemployment in the United States has been low in the past couple of years and has recently decreased further; some economists have speculated that in certain markets, the U.S. could be at or near full employment. This phenomenon has made finding sufficient eligible candidates to meet employers’
5

demands more challenging and further increases in the employment rates could compound these difficulties. Any shortage of candidates could materially adversely affect the Company.
The Company operates in a highly competitive business and may be unable to retain clients or market share. The staffing services business is highly competitive and, because it is a service business, the barriers to entry are quite low. There are many competitors, some of which have greater resources than the Company, and new competitors are entering the market all the time. In addition, long-term contracts form a negligible portion of the Company’s revenue. Therefore, there can be no assurance that the Company will be able to retain clients or market share in the future. Nor can there be any assurance that the Company will, in light of competitive pressures, be able to remain profitable or, if profitable, maintain its current profit margins.
The Company may incur potential liability to employees and clients. The Company’s temporary services business entails employing individuals on a temporary basis and placing such individuals in clients’ workplaces. The Company’s ability to control the workplace environment is limited. As the employer of record of its temporary employees, the Company incurs a risk of liability to its temporary employees for various workplace events, including claims of physical injury, discrimination, harassment or failure to protect confidential personal information. While such claims have not historically had a material adverse effect upon the Company, there can be no assurance that such claims in the future will not result in adverse publicity or have a material adverse effect upon the Company. The Company also incurs a risk of liability to its clients resulting from allegations of errors, omissions or theft by its temporary employees, or allegations of misuse of client confidential information. In many cases, the Company has agreed to indemnify its clients in respect of these types of claims. The Company maintains insurance with respect to many of such claims. While such claims have not historically had a material adverse effect upon the Company, there can be no assurance that the Company will continue to be able to obtain insurance at a cost that does not have a material adverse effect upon the Company or that such claims (whether by reason of the Company not having sufficient insurance or by reason of such claims being outside the scope of the Company’s insurance) will not have a material adverse effect upon the Company.
The Company is dependent on its management personnel and employees and a failure to attract and retain such personnel could harm its business. The Company is engaged in the services business. As such, its success or failure is highly dependent upon the performance of its management personnel and employees, rather than upon technology or upon tangible assets (of which the Company has few). There can be no assurance that the Company will be able to attract and retain the personnel that are essential to its success.
The Company’s business is subject to extensive government regulation and a failure to comply with regulations could harm its business. The Company’s business is subject to regulation or licensing in many states in the U.S. and in certain foreign countries. While the Company has had no material difficulty complying with regulations in the past, there can be no assurance that the Company will be able to continue to obtain all necessary licenses or approvals or that the cost of compliance will not prove to be material. Any inability of the Company to comply with government regulation or licensing requirements could materially adversely affect the Company. Further, changes to existing regulation or licensing requirements could impose additional costs and other burdens or limitations on the Company’s operations. In addition, the Company’s temporary services business entails employing individuals on a temporary basis and placing such individuals in clients’ workplaces. Increased government regulation of the workplace or of the employer-employee relationship, or judicial or administrative proceedings related to such regulation, could materially adversely affect the Company. In addition, to the extent that government regulation imposes increased costs upon the Company, such as unemployment insurance taxes, there can be no assurance that such costs will not adversely impact the Company’s profit margins. Further, lawsuits or other proceedings related to the Company’s compliance with government regulations or licensing requirements could materially adversely affect the Company. For example, the Company is currently named as a defendant in litigation challenging its compliance with the Fair Credit Reporting Act. It is not possible to predict the outcome of such litigation; however, such litigation or any future lawsuits or proceedings related to the Company’s compliance with government regulation or licensing requirements could consume substantial amounts of the Company’s financial and managerial resources and might result in adverse publicity, regardless of the ultimate outcome of any such lawsuits or other proceedings. An unfavorable outcome with respect to such litigation or any future lawsuits or proceedings could, individually or in the aggregate, cause the Company to incur substantial liabilities that may have a material adverse effect upon the Company’s business, financial condition or results of operations.
Health care reform could increase the costs of the Company’s temporary staffing operations. In March 2010, the Patient Protection and Affordable Care Act and the Health Care and Education Reconciliation Act of 2010 (the “PPACA”) was signed into law in the United States. In 2015, the Company redesigned its employee benefits to offer health insurance coverage to its temporary candidates in order to meet the requirements of the PPACA’s employer mandate.
It is likely that President Trump and the U.S. Congress will continue to seek to modify, repeal, or otherwise invalidate all, or certain provisions of, the PPACA. President Trump has issued multiple executive orders in support of repealing the PPACA,
6

in whole or in part, and the U.S. Congress has made several attempts to repeal or modify the PPACA. It is unclear at this point what the scope of any future such legislation will be and when it will become effective. Because of the uncertainty surrounding this replacement health care reform legislation, we cannot predict with any certainty the likely impact of the PPACA’s repeal or the adoption of any other health care reform legislation on the Company’s financial condition or operating results. Whether or not there is alternative health care legislation enacted in the U.S., there is likely to be significant disruption to the health care market in the coming months and years and the costs of the Company’s health care expenditures may increase.
The Company’s computer and communications hardware and software systems are vulnerable to damage and interruption. The Company’s ability to manage its operations successfully is critical to its success and largely depends upon the efficient and uninterrupted operation of its computer and communications hardware and software systems, some of which are managed by third-party vendors. The Company’s primary computer systems and operations are vulnerable to damage or interruption from power outages, computer and telecommunications failures, computer viruses, security breaches, catastrophic events and errors in usage by the Company’s employees and those of the Company’s vendors. In particular, the Company’s employees or vendors may have access or exposure to personally identifiable or otherwise confidential information and customer data and systems, the misuse of which could result in legal liability. Cyber-attacks, including attacks motivated by grievances against the business services industry in general or against the Company in particular, may disable or damage its systems. It is possible that the Company’s security controls or those of its third-party vendors over personal and other data and other practices it follows may not prevent the improper access to or disclosure of personally identifiable or otherwise confidential information. Such disclosure or damage to the Company’s systems could harm its reputation and subject it to government sanctions and liability under its contracts and laws that protect personal data and confidential information, resulting in increased costs or loss of revenue. The potential risk of security breaches and cyber-attacks may increase as the Company introduces new service offerings.
Changes in data privacy and protection laws and regulations in respect of control of personal information could increase the Company’s costs or otherwise adversely impact its operations. In the ordinary course of business, the Company collects, uses, and retains personal information from its employees, employment candidates, and contractors, including, without limitation, full names, government-issued identification numbers, addresses, birth dates, and payroll-related information. The possession and use of personal information in conducting the Company’s business subjects it to a variety of complex and evolving domestic and foreign laws and regulations regarding data privacy, protection and security, which, in many cases, apply not only to third-party transactions, but also to transfers of information among the Company and its subsidiaries. For example, the European Union’s General Data Protection Regulation (“GDPR”), which becomes effective in May 2018, will impose more stringent operational requirements for entities processing personal information, such as stronger safeguards for data transfers to countries outside the European Union and stronger enforcement authorities and mechanisms. Complying with the enhanced obligations imposed by the GDPR and other current and future laws and regulations relating to data transfer, residency, privacy and protection may increase the Company’s operating costs and require significant management time and attention, while any failure by the Company or its subsidiaries to comply with applicable laws could result in governmental enforcement actions, fines, and other penalties that could potentially have an adverse effect on the Company’s operations and reputation.
Failure to maintain adequate financial and management processes and controls could lead to errors in the Company’s financial reporting. Failure to maintain adequate financial and management processes and controls could lead to errors in the Company’s financial reporting. If the Company’s management is unable to certify the effectiveness of its internal controls or if its independent registered public accounting firm cannot render an opinion on the effectiveness of its internal control over financial reporting, or if material weaknesses in the Company’s internal controls are identified, the Company could be subject to regulatory scrutiny and a loss of public confidence. In addition, if the Company does not maintain adequate financial and management personnel, processes and controls, it may not be able to accurately report its financial performance on a timely basis, which could cause its stock price to fall.
The Company’s results of operations and ability to grow could be materially negatively affected if it cannot successfully keep pace with technological changes in the development and implementation of its services. The Company’s success depends on its ability to keep pace with rapid technological changes in the development and implementation of its services. The Company’s business is reliant on a variety of technologies, including those which support hiring and tracking, order management, billing, and client data analytics. If the Company does not sufficiently invest in new technology and industry developments, appropriately implement new technologies, or evolve its business at sufficient speed and scale in response to such developments, or if it does not make the right strategic investments to respond to these developments, the Company’s services, results of operations, and ability to develop and maintain its business could be negatively affected.
The demand for the Company’s services related to Sarbanes-Oxley or other regulatory compliance may decline. The operations of both the staffing services business and Protiviti include services related to Sarbanes-Oxley and other regulatory compliance. There can be no assurance that there will be ongoing demand for these services. For example, the Jumpstart Our
7

Business Startup (“JOBS”) Act signed into law in April of 2012 allows most companies going public in the U.S. to defer implementation of some of the provisions of Sarbanes-Oxley for up to five years after their initial public offering. Similarly there are a number of proposals currently being considered by the U.S. Congress to further delay or, in some cases, remove the requirements of Sarbanes-Oxley for a number of public companies. Further, many analysts are expecting the U.S. Congress and President Trump to seek to repeal or modify legislation that is viewed as having over-regulated certain sectors of the U.S. economy and decreased the incentive for U.S. companies to go public and their ability to effectively compete with foreign competition. These or other similar modifications of the regulatory requirements could decrease demand for Protiviti’s services.
Long-term contracts do not comprise a significant portion of the Company’s revenue. Because long-term contracts are not a significant part of the Company’s staffing services business, future results cannot be reliably predicted by considering past trends or extrapolating past results. Additionally, the Company’s clients will frequently enter into non-exclusive arrangements with several firms, which the client is generally able to terminate on short notice and without penalty. The nature of these arrangements further exacerbates the difficulty in predicting our future results.
U.S. federal tax regulations and interpretations could adversely affect the Company. On December 22, 2017, the Tax Cuts and Jobs Act (the “TCJA”) was signed into law. The TCJA resulted in a revaluation of the Company’s estimated deferred income tax net assets and a resulting one-time non-cash charge to its provision for income taxes in an amount of $34 million, or $.27 per share, in the fourth quarter of 2017. See Item 7. Management’s Discussion and Analysis of Financial Condition and Results of Operations and the Company’s Consolidated Financial Statements and the Notes thereto contained in Item 8. Financial Statements and Supplementary Data. In addition, the TCJA contains significant changes to corporate taxation, including the reduction of the corporate tax rate from 35% to 21% beginning in 2018, limitation for net operating losses to 80% of current year taxable income and elimination of net operating loss carrybacks, one time taxation of offshore earnings at reduced rates regardless of whether they are repatriated, elimination of U.S. tax on foreign earnings (subject to certain important exceptions), and modifying or repealing many business deductions (including the ability to deduct executive compensation expenses in excess of $1 million in virtually all instances). Notwithstanding the reduction in the corporate income tax rate, the overall impact of these changes on the Company’s results of operations is uncertain and will likely evolve as new regulations and interpretations relating to the TCJA are implemented. In addition, various political figures have pledged their support to overturning or modifying key aspects of the TCJA which could further increase the uncertainty relating to the impact of this or any future tax legislation on the Company’s results of operations.
Protiviti may be unable to attract and retain key personnel. Protiviti is a services business, and is dependent upon its ability to attract and retain qualified, skilled personnel. While Protiviti has retained its key personnel to date, there can be no assurance that it will continue to be able to do so.
Protiviti operates in a highly competitive business and faces competitors who are significantly larger and have more established reputations. Protiviti operates in a highly competitive business. As with the Company’s staffing services business, the barriers to entry are quite low. There are many competitors, some of which have greater resources than Protiviti and many of which have been in operation far longer than Protiviti. In particular, Protiviti faces competition from the “big four” accounting firms, which have been in operation for a considerable period of time and have established reputations and client bases. Because the principal factors upon which competition is based are reputation, technology, tools, project methodologies, price of services and depth of skills of personnel, there can be no assurance that Protiviti will be successful in attracting and retaining clients or be able to maintain the technology, personnel and other requirements to successfully compete.
Protiviti’s operations could subject it to liability. The business of Protiviti consists of providing business consulting and internal audit services. Liability could be incurred or litigation could be instituted against the Company or Protiviti for claims related to these activities or to prior transactions or activities. There can be no assurance that such liability or litigation will not have a material adverse impact on Protiviti or the Company.

Item 3. Legal Proceedings
On March 13, 2014, Plaintiff Leonor Rodriguez, on her own behalf and on behalf of a putative class of allegedly similarly situated individuals, filed a complaint against the Company in the Superior Court of California, San Diego County. The complaint alleges that a putative class of current and former employees of the Company working in California since March 13, 2011 were denied compensation for the time they spent interviewing with clients of the Company as well as performing activities related to the interview process. Rodriguez seeks recovery on her own behalf and on behalf of the putative class in an unspecified amount for this allegedly unpaid compensation. Rodriguez also seeks recovery of an unspecified amount for the alleged failure of the Company to provide her and the putative class with accurate wage statements. Rodriguez also seeks an unspecified amount of other damages, attorneys’ fees, and statutory penalties, including but not limited to statutory penalties on behalf of herself and other allegedly “aggrieved employees” as defined by California’s Labor Code Private Attorney General Act (“PAGA”). On October 10, 2014, the Court granted a motion by the Company to compel all of Rodriguez’s claims, except the PAGA claim, to individual arbitration. At this stage of the litigation, it is not feasible to predict the outcome of or a range of loss, should a loss occur, from this proceeding and, accordingly, no amounts have been provided in the Company’s Financial Statements. The Company believes it has meritorious defenses to the allegations and the Company intends to continue to vigorously defend against the litigation.
On March 23, 2015, Plaintiff Jessica Gentry, on her own behalf and on behalf of a putative class of allegedly similarly situated individuals, filed a complaint against the Company in the Superior Court of California, San Francisco County, which was subsequently amended on October 23, 2015. The complaint, which was filed by the same plaintiffs’ law firm that brought the Rodriguez matter described above, alleges claims similar to those alleged in Rodriguez. Specifically, the complaint alleges that a putative class of current and former employees of the Company working in California since March 13, 2010 were denied compensation for the time they spent interviewing “for temporary and permanent employment opportunities” as well as performing activities related to the interview process. Gentry seeks recovery on her own behalf and on behalf of the putative class in an unspecified amount for this allegedly unpaid compensation. Gentry also seeks recovery of an unspecified amount for the alleged failure of the Company to provide her and the putative class with accurate wage statements. Gentry also seeks an unspecified amount of other damages, attorneys’ fees, and statutory penalties, including penalties for allegedly not paying all wages due upon separation to former employees and statutory penalties on behalf of herself and other allegedly “aggrieved employees” as defined by PAGA. On January 4, 2016, the Court denied a motion by the Company to compel all of Gentry’s claims, except the PAGA claim, to individual arbitration. At this stage of the litigation, it is not feasible to predict the outcome of or a range of loss, should a loss occur, from this proceeding and, accordingly, no amounts have been provided in the Company’s Financial Statements. The Company believes it has meritorious defenses to the allegations and the Company intends to continue to vigorously defend against the litigation.
The Company is involved in a number of other lawsuits arising in the ordinary course of business. While management does not expect any of these other matters to have a material adverse effect on the Company’s results of operations, financial position or cash flows, litigation is subject to certain inherent uncertainties.

Item 7. Management’s Discussion and Analysis of Financial Condition and Results of Operations
Certain information contained in Management’s Discussion and Analysis and in other parts of this report may be deemed forward-looking statements regarding events and financial trends that may affect the Company’s future operating results or financial positions. These statements may be identified by words such as “estimate”, “forecast”, “project”, “plan”, “intend”, “believe”, “expect”, “anticipate”, or variations or negatives thereof or by similar or comparable words or phrases. Forward-looking statements are subject to risks and uncertainties that could cause actual results to differ materially from those expressed in the statements. These risks and uncertainties include, but are not limited to, the following: changes to or new interpretations of U.S. or international tax regulations; the global financial and economic situation; changes in levels of unemployment and other economic conditions in the United States or foreign countries where the Company does business, or in particular regions or industries; reduction in the supply of candidates for temporary employment or the Company’s ability to attract candidates; the entry of new competitors into the marketplace or expansion by existing competitors; the ability of the Company to maintain existing client relationships and attract new clients in the context of changing economic or competitive conditions; the impact of competitive pressures, including any change in the demand for the Company’s services, on the Company’s ability to maintain its margins; the possibility of the Company incurring liability for its activities, including the activities of its temporary employees, or for events impacting its temporary employees on clients’ premises; the possibility that adverse publicity could impact the Company’s ability to attract and retain clients and candidates; the success of the Company in attracting, training, and retaining qualified management personnel and other staff employees; the Company’s ability to comply with governmental regulations affecting personnel services businesses in particular or employer/employee relationships in general; whether there will be ongoing demand for Sarbanes-Oxley or other regulatory compliance services; the Company’s reliance on short-term contracts for a significant percentage of its business; litigation relating to prior or current transactions or activities, including litigation that may be disclosed from time to time in the Company’s Securities and Exchange Commission (“SEC”) filings; the ability of the Company to manage its international operations and comply with foreign laws and regulations; the impact of fluctuations in foreign currency exchange rates; the possibility that the additional costs the Company will incur as a result of health care reform legislation may adversely affect the Company’s profit margins or the demand for the Company’s services; the possibility that the Company’s computer and communications hardware and software systems could be damaged or their service interrupted; and the possibility that the Company may fail to maintain adequate financial and management controls and as a result suffer errors in its financial reporting. Additionally, with respect to Protiviti, other risks and uncertainties include the fact that future success will depend on its ability to retain employees and attract clients; there can be no assurance that there will be ongoing demand for Sarbanes-Oxley or other regulatory compliance services; failure to produce projected revenues could adversely affect financial results; and there is the possibility of involvement in litigation relating to prior or current transactions or activities. Because long-term contracts are not a significant part of the Company’s business, future results cannot be reliably predicted by considering past trends or extrapolating past results. Further information regarding these and other risks and uncertainties is contained in Item 1A. “Risk Factors.”
Executive Overview
Demand for the Company’s temporary and consultant staffing, permanent placement staffing and risk consulting and internal audit services is largely dependent upon general economic and labor trends both domestically and abroad. Correspondingly, financial results for the year ended December 31, 2017, were positively impacted by improving global economic conditions as the year progressed. Annual net service revenues reached $5.27 billion in 2017, a slight increase from the prior year. Full-year 2017 net income decreased 15% to $291 million and diluted net income per share decreased 13% to $2.33. Included in 2017 net income was a one-time, non-cash charge to the Company's provision for income taxes of $34 million, or $.27 per share, resulting from the recently enacted TCJA. For 2017, revenue growth for temporary and consultant staffing was essentially flat compared to last year while permanent placement staffing and risk consulting and internal audit services increased 5% and 2%, respectively.
We believe that the Company is well positioned in the current macroeconomic environment. The United States economic backdrop during 2017 was stable for the Company as real gross domestic product (“GDP”) grew 2.3%, while the unemployment rate declined from 4.7% in December 2016 to 4.1% in December 2017. In the United States, the number of job openings has exceeded the number of hires since February 2015, creating competition for skilled talent that increases the Company’s value to clients. The U.S. labor market continues to tighten, resulting in talent shortages in some occupations and higher demand for our services. The secular demand for temporary staffing is also ongoing. The number of temporary workers as a percentage of the overall U.S. workforce remains near an all-time high, a sign employers are building flexible staffing options into their human resource plans with increasing frequency.
13

Protiviti continues to see solid growth in its risk and compliance and internal audit and financial advisory practice areas. Protiviti also is expanding its solutions in areas such as data and analytics, and cybersecurity.
We monitor various economic indicators and business trends in all of the countries in which we operate to anticipate demand for the Company’s services. We evaluate these trends to determine the appropriate level of investment, including personnel, which will best position the Company for success in the current and future global macroeconomic environment. The Company’s investments in headcount are typically structured to proactively support and align with expected revenue growth trends. As such, during 2017, we added headcount in our temporary and consultant and permanent placement staffing services, while risk consulting and internal audit headcount remained essentially flat.
We have limited visibility into future revenues not only due to the dependence on macroeconomic conditions noted above, but also because of the relatively short duration of the Company’s client engagements. Accordingly, we typically assess headcount and other investments on at least a quarterly basis. That said, based on current trends and conditions, we expect headcount levels for our full-time staff to be modestly higher for each of our reporting segments throughout the first quarter of 2018.
Capital expenditures in 2017 totaled $41 million, approximately 46% of which represented investments in software initiatives and technology infrastructure, both of which are important to the Company’s future growth opportunities. While upgrades to enterprise resource planning and project management applications were completed in 2017, we continue to invest in digital technology initiatives designed to enhance our service offerings to both clients and candidates. Capital expenditures also included amounts spent on tenant improvements and furniture and equipment in the Company’s leased offices. We currently expect that 2018 capital expenditures will range from $45 million to $55 million.
Critical Accounting Policies and Estimates
As described below, the Company’s most critical accounting policies and estimates are those that involve subjective decisions or assessments.
Accounts Receivable Allowances. The Company maintains allowances for estimated losses resulting from (i) the inability of its customers to make required payments, (ii) temporary placement sales adjustments, and (iii) permanent placement candidates not remaining with the client through the 90-day guarantee period, commonly referred to as “fall offs”. The Company establishes these allowances based on its review of customers’ credit profiles, historical loss statistics and current trends. The adequacy of these allowances is reviewed each reporting period. Historically, the Company’s actual losses and credits have been consistent with these allowances. As a percentage of gross accounts receivable, the Company’s accounts receivable allowances totaled 4.3% and 4.5% as of December 31, 2017 and 2016, respectively. As of December 31, 2017, a five-percentage point deviation in the Company’s accounts receivable allowances balance would have resulted in an increase or decrease in the allowance of $1.7 million. Although future results cannot always be predicted by extrapolating past results, management believes that it is reasonably likely that future results will be consistent with historical trends and experience. However, if the financial condition of the Company’s customers were to deteriorate, resulting in an impairment of their ability to make payments, or if unexpected events or significant future changes in trends were to occur, additional allowances may be required.
Income Tax Assets and Liabilities. In establishing its deferred income tax assets and liabilities, the Company makes judgments and interpretations based on the enacted tax laws and published tax guidance that are applicable to its operations. Deferred tax assets and liabilities are measured and recorded using current enacted tax rates, which the Company expects will apply to taxable income in the years in which those temporary differences are recovered or settled. The likelihood of a material change in the Company’s expected realization of these assets is dependent on future taxable income, its ability to use foreign tax credit carryforwards and carrybacks, final U.S. and foreign tax settlements, and the effectiveness of its tax planning in the various relevant jurisdictions.
On December 22, 2017, the President signed TCJA into law. Effective January 1, 2018, among other changes, TCJA reduces the federal corporate tax rate to 21 percent, provides for a deemed repatriation and taxation at reduced rates of certain foreign earnings (a “transition tax”), and establishes new mechanisms to tax certain foreign earnings going forward. Similar to other large multinational companies, TCJA has wide ranging implications for the Company. The Company has recorded provisional amounts and a reasonable estimate of TCJA’s impact on its financial statements. As guidance regarding implementation of various provisions of TCJA is released by the U.S. Government over the course of 2018, the Company’s estimates may need to be adjusted accordingly.
In December 2017, the SEC issued Staff Accounting Bulletin No. 118, Income Tax Accounting Implications of the Tax Cuts and Jobs Act (“SAB 118”), which allows the Company to record provisional amounts during a measurement period not to
14

extend beyond one year of the enactment date. Since TCJA was passed late in the fourth quarter of 2017, and ongoing guidance and accounting interpretations are expected over the next 12 months, the Company considers the accounting of the transition tax, deferred tax remeasurements, and other items to be incomplete due to the forthcoming guidance and ongoing analysis of its final tax positions for the year ended December 31, 2017. The Company expects to complete its analysis within the measurement period in accordance with SAB 118.
The Company also evaluates the need for valuation allowances to reduce the deferred tax assets to realizable amounts. Management evaluates all positive and negative evidence and uses judgment regarding past and future events, including operating results, to help determine when it is more likely than not that all or some portion of the deferred tax assets may not be realized. When appropriate, a valuation allowance is recorded against deferred tax assets to offset future tax benefits that may not be realized. Valuation allowances of $20.2 million and $18.9 million were recorded as of December 31, 2017 and 2016, respectively. The valuation allowances recorded relate primarily to net operating losses in certain foreign operations. If such losses are ultimately utilized to offset future operating income, the Company will recognize a tax benefit up to the full amount of the related valuation reserve.
While management believes that its judgments and interpretations regarding income taxes are appropriate, significant differences in actual experience may materially affect the future financial results of the Company.
Goodwill Impairment. The Company assesses the impairment of goodwill annually in the second quarter, or more often if events or changes in circumstances indicate that the carrying value may not be recoverable in accordance with Financial Accounting Standards Board (“FASB”) authoritative guidance. The Company completed its annual goodwill impairment analysis as of June 30, 2017, and determined that no adjustment to the carrying value of goodwill was required. There were no events or changes in circumstances since the annual goodwill impairment assessment that caused the Company to perform an interim impairment assessment.
The Company follows FASB authoritative guidance utilizing a two-step approach for determining goodwill impairment. In the first step the Company determines the fair value of each reporting unit utilizing a present value technique derived from a discounted cash flow methodology. For purposes of this assessment the Company’s reporting units are its lines of business. The fair value of the reporting unit is then compared to its carrying value. If the fair value of the reporting unit exceeds the carrying value of the net assets assigned to that unit, goodwill is not impaired and no further testing is performed. The second step under the FASB guidance is contingent upon the results of the first step. To the extent a reporting unit’s carrying value exceeds its fair value, an indication exists that the reporting unit’s goodwill may be impaired and the Company must perform a second more detailed impairment assessment. The second step involves allocating the reporting unit’s fair value to its net assets in order to determine the implied fair value of the reporting unit’s goodwill as of the assessment date. The implied fair value of the reporting unit’s goodwill is then compared to the carrying amount of goodwill to quantify an impairment charge as of the assessment date.
The Company’s reporting units are Accountemps, Robert Half Finance & Accounting, OfficeTeam, Robert Half Technology, Robert Half Management Resources and Protiviti, which had goodwill balances at December 31, 2017, of $127.5 million, $26.2 million, $0.0 million, $7.0 million, $0.0 million and $50.2 million, respectively, totaling $210.9 million. There were no changes to the Company’s reporting units or to the allocations of goodwill by reporting unit for the year ended December 31, 2017.
The goodwill impairment assessment is based upon a discounted cash flow analysis. The estimate of future cash flows is based upon, among other things, a discount rate and certain assumptions about expected future operating performance. The discount rate for all reporting units was determined by management based on estimates of risk free interest rates, beta and market risk premiums. The discount rate used was compared to the rate published in various third party research reports, which indicated that the rate was within a range of reasonableness. The primary assumptions related to future operating performance include revenue growth rates and profitability levels. In addition, the impairment assessment requires that management make certain judgments in allocating shared assets and liabilities to the balance sheets of the reporting units. Solely for purposes of establishing inputs for the fair value calculations described above related to its annual goodwill impairment testing, the Company made the following assumptions. The Company assumed that year-to-date trends through the date of the most recent assessment would continue for all reporting units through 2017, using unique assumptions for each reporting unit. In addition, the Company applied profitability assumptions consistent with each reporting unit’s historical trends at various revenue levels and, for years 2019 and beyond, used a 3.5% growth factor. This rate is comparable to the Company’s most recent ten-year annual compound revenue growth rate. The model used to calculate fair value extends a total of 10 years with a terminal value calculation at the end of the 10 year period. In its most recent calculation, the Company used a 10.3% discount rate, which is slightly higher than the 9.8% discount rate used for the Company’s test during the second quarter of 2016. This increase in discount rate is attributable to increases in the risk free rate and the equity market risk premium, offset by a slight decrease in beta.
15

In order to evaluate the sensitivity of the fair value calculations on the goodwill impairment test, the Company applied hypothetical decreases to the fair values of each reporting unit. The Company determined that hypothetical decreases in fair value of at least 62% would be required before any reporting unit would have a carrying value in excess of its fair value.
Given the current economic environment and the uncertainties regarding the impact on the Company’s business, there can be no assurance that the Company’s estimates and assumptions made for purposes of the Company’s goodwill impairment testing will prove to be accurate predictions of the future. If the Company’s assumptions regarding forecasted revenue or profitability growth rates of certain reporting units are not achieved, the Company may be required to recognize goodwill impairment charges in future periods. It is not possible at this time to determine if any such future impairment charge would result or, if it does, whether such charge would be material.
Workers’ Compensation. Except for states which require participation in state-operated insurance funds, the Company retains the economic burden for the first $0.5 million per occurrence in workers’ compensation claims. Workers’ compensation includes ongoing healthcare and indemnity coverage for claims and may be paid over numerous years following the date of injury. Claims in excess of $0.5 million are insured. Workers’ compensation expense includes the insurance premiums for claims in excess of $0.5 million, claims administration fees charged by the Company’s workers’ compensation administrator, premiums paid to state-operated insurance funds, and an estimate for the Company’s liability for Incurred But Not Reported (“IBNR”) claims and for the ongoing development of existing claims. Total workers’ compensation expense was $6.2 million, $0.9 million and $4.6 million, representing 0.15%, 0.02% and 0.11% of applicable U.S. revenue for the years ended December 31, 2017, 2016 and 2015, respectively.
The reserves for IBNR claims and for the ongoing development of existing claims in each reporting period include estimates. The Company has established reserves for workers’ compensation claims using loss development rates which are estimated using periodic third party actuarial valuations based upon historical loss statistics which include the Company’s historical frequency and severity of workers’ compensation claims, and an estimate of future cost trends. While management believes that its assumptions and estimates are appropriate, significant differences in actual experience or significant changes in assumptions may materially affect the Company’s future results. Based on the Company’s results for the year ended December 31, 2017, a five-percentage point deviation in the Company’s estimated loss development rates would have resulted in an increase or decrease in the reserve of $0.2 million.
Stock-based Compensation. Under various stock plans, officers, employees and outside directors have received or may receive grants of restricted stock, stock units, stock appreciation rights or options to purchase common stock.
The Company recognizes compensation expense equal to the grant-date fair value for all stock-based payment awards that are expected to vest. This expense is recorded on a straight-line basis over the requisite service period of the entire award, unless the awards are subject to performance conditions, in which case the Company recognizes compensation expense over the requisite service period of each separate vesting tranche. The Company determines the grant-date fair value of its restricted stock and stock unit awards using the fair market value of its stock on the grant date, unless the awards are subject to market conditions, in which case the Company utilizes a binomial-lattice model (i.e., Monte Carlo simulation model). The Monte Carlo simulation model utilizes multiple input variables to determine the stock-based compensation expense.
No stock appreciation rights have been granted under the Company’s existing stock plans. The Company has not granted any options to purchase common stock since 2006.
For the years ended December 31, 2017, 2016 and 2015, compensation expense related to restricted stock and stock units was $42.2 million, $42.7 million and $41.3 million, respectively, of which $11.4 million, $11.0 million and $11.1 million was related to grants made in 2017, 2016 and 2015, respectively. Based on the Company’s results for the year ended December 31, 2017, a one-percentage point deviation in the estimated forfeiture rates would have resulted in a $0.4 million increase or decrease in compensation expense related to restricted stock and stock units.
Recent Accounting Pronouncements

Results of Operations
Demand for the Company’s temporary and consultant staffing, permanent placement staffing and risk consulting and internal audit services is largely dependent upon general economic and labor market conditions both domestically and abroad. Correspondingly, results of operations for the year ended December 31, 2017, were positively impacted by improving global economic conditions as the year progressed. Because of the inherent difficulty in predicting economic trends and the absence of
16

material long-term contracts in any of the Company’s business units, future demand for the Company’s services cannot be forecasted with certainty. We believe the Company is well positioned in the current United States macroeconomic environment.
The Company’s temporary and permanent staffing business has 323 offices in 42 states, the District of Columbia and 17 foreign countries, while Protiviti has 56 offices in 23 states and 11 foreign countries.
Non-GAAP Financial Measures
The financial results of the Company are prepared in conformity with accounting principles generally accepted in the United States of America (“GAAP”) and the rules of the SEC. To help readers understand the Company’s financial performance, the Company supplements its GAAP financial results with revenue growth rates derived from non-GAAP revenue amounts.
Variations in the Company’s financial results include the impact of changes in foreign currency exchange rates and billing days. The Company provides “same billing days and constant currency” revenue growth calculations to remove the impact of these items. These calculations show the year-over-year revenue growth rates for the Company’s reportable segments on both a reported basis and also on a same day, constant-currency basis for global, U.S. and international operations. The Company has provided this data because management believes it better reflects the Company’s actual revenue growth rates and aids in evaluating revenue trends over time. The Company expresses year-over-year revenue changes as calculated percentages using the same number of billing days and constant currency exchange rates.
In order to calculate constant currency revenue growth rates, as reported amounts are retranslated using foreign currency exchange rates from the prior year’s comparable period. Management then calculates a global, weighted-average number of billing days for each reporting period based upon input from all countries and all lines of business. In order to remove the fluctuations caused by comparable periods having different billing days, the Company calculates same billing day revenue growth rates by dividing each comparative period’s reported revenues by the calculated number of billing days for that period, to arrive at a per billing day amount. Same billing day growth rates are then calculated based upon the per billing day amounts. The term “same billing days and constant currency” means that the impact of different billing days has been removed from the constant currency calculation.
The non-GAAP financial measures provided herein may not provide information that is directly comparable to that provided by other companies in the Company’s industry, as other companies may calculate such financial results differently. The Company’s non-GAAP financial measures are not measurements of financial performance under GAAP, and should not be considered as alternatives to actual revenue growth derived from revenue amounts presented in accordance with GAAP. The Company does not consider these non-GAAP financial measures to be a substitute for, or superior to, the information provided by GAAP financial results. A reconciliation of the same-day, constant-currency revenue growth rates to the reported revenue growth rates is provided herein.
Refer to Item 7a. “Quantitative and Qualitative Disclosures About Market Risk” for further discussion of the impact of foreign currency exchange rates on the Company’s results of operations and financial condition.
Years ended December 31, 2017 and 2016
Revenues. The Company’s revenues were $5.27 billion for the year ended December 31, 2017, increasing by 0.3% compared to $5.25 billion for the year ended December 31, 2016. Revenues from foreign operations represented 22% and 20% of total revenues for the years ended December 31, 2017 and 2016, respectively. The Company analyzes its revenues for three reportable segments: temporary and consultant staffing, permanent placement staffing and risk consulting and internal audit services. In 2017, revenues for permanent placement staffing and risk consulting and internal audit services were up and revenues for temporary and consultant staffing were down slightly compared to 2016. Revenue growth was strongest internationally, most notably within Europe. Contributing factors for each reportable segment are discussed below in further detail.
Temporary and consultant staffing revenues were $4.01 billion for the year ended December 31, 2017, remained essentially flat compared to revenues of $4.03 billion for the year ended December 31, 2016. Key drivers of temporary and consultant staffing revenues include average hourly bill rates and the number of hours worked by the Company’s temporary employees on client engagements. On a same-day, constant-currency basis, temporary and consultant staffing revenues decreased 0.3% for 2017, compared to 2016, due primarily to fewer hours worked by the Company’s temporary employees, partially offset by a 2.7% increase in average bill rates. In the U.S., 2017 revenues decreased 3.1% on an as reported basis and 2.8% on a same-day basis, compared to 2016. For the Company’s international operations, 2017 revenues increased 11.0% on an as reported basis and 10.1% on a same-day, constant-currency basis, compared to 2016.
17

Permanent placement staffing revenues were $439 million for the year ended December 31, 2017, increasing by 4.7% compared to revenues of $419 million for the year ended December 31, 2016. Key drivers of permanent placement staffing revenues consist of the number of candidate placements and average fees earned per placement. On a same-day, constant-currency basis, permanent placement staffing revenues increased 4.9% for 2017 compared to 2016 due to increases in both the number of placements and average fees per placement. In the U.S., 2017 revenues increased 0.9% on an as reported basis and 1.3% on a same-day basis, compared to 2016. For the Company’s international operations, 2017 revenues increased 14.1% on an as reported basis, and on a same-day, constant-currency basis increased 13.5%, compared to 2016. Historically, demand for permanent placement services is even more sensitive to economic and labor market conditions than demand for temporary and consulting staffing and this is expected to continue.
Risk consulting and internal audit services revenues were $817 million for the year ended December 31, 2017, increasing by 1.5% compared to revenues of $804 million for the year ended December 31, 2016. Key drivers of risk consulting and internal audit services revenues are the billable hours worked by consultants on client engagements and average hourly bill rates. On a same-day, constant-currency basis, risk consulting and internal audit services revenues increased 1.9% for 2017 compared to 2016, driven primarily by increases in billable hours and billing rates. In the U.S., 2017 revenues remained essentially flat on an as reported basis, and increased 0.3% on a same-day basis, compared to 2016. For the Company’s international operations, 2017 revenues increased 9.5% on an as reported basis, or 10.2% on a same-day, constant-currency basis, compared to 2016.
A reconciliation of the non-GAAP year-over-year revenue growth rates to the as reported year-over-year revenue growth rates for the year ended December 31, 2017, is presented in the following table:

| Global |  | United States |  | International
Temporary and consultant staffing |  |  |  |  |  |  |  |  |  |  |
As Reported |  | -0.4 | % |  |  |  | -3.1 | % |  |  |  | 11.0 | % |

Gross Margin. The Company’s gross margin dollars were $2.16 billion for both the years ended December 31, 2017 and 2016. Contributing factors for each reportable segment are discussed below in further detail.
Gross margin dollars for temporary and consultant staffing represent revenues less direct costs of services, which consist of payroll, payroll taxes and benefit costs for temporary employees, and reimbursable expenses. The key drivers of gross margin are: i) pay/bill spreads, which represent the differential between wages paid to temporary employees and amounts billed to clients; ii) fringe costs, which are primarily composed of payroll taxes and benefit costs for temporary and consultant staffing employees; and iii) conversion revenues, which are earned when a temporary position converts to a permanent position with the Company’s client. Gross margin dollars for the Company’s temporary and consultant staffing division were $1.49 billion for the year ended December 31, 2017, down 1.1% from $1.51 billion for the year ended December 31, 2016. As a percentage of revenues, gross margin dollars for temporary and consultant staffing were 37.2% in 2017, down from 37.5% in 2016. This year-over-year decline in gross margin percentage is primarily attributable to higher workers’ compensation costs and other fringe benefit costs. The Company’s 2017 results include $0.9 million in workers’ compensation credits, pursuant to third-party actuarial reviews of the Company’s workers’ compensation accruals. This compares to a credit of $5.8 million in the year-ago period.
18

Gross margin dollars for permanent placement staffing represent revenues less reimbursable expenses. Gross margin dollars for the Company’s permanent placement staffing division were $438 million for the year ended December 31, 2017, up 4.7% from $419 million for the year ended December 31, 2016. Because reimbursable expenses for permanent placement staffing services are de minimis, the increase in gross margin dollars is substantially explained by the increase in revenues previously discussed.
Gross margin dollars for risk consulting and internal audit services represent revenues less direct costs of services, which consist primarily of professional staff payroll, payroll taxes, benefit costs and reimbursable expenses. The primary drivers of risk consulting and internal audit services gross margin are: i) the relative composition of and number of professional staff and their respective pay and bill rates; and ii) staff utilization, which is the relationship of time spent on client engagements in proportion to the total time available for the Company’s risk consulting and internal audit services staff. Gross margin dollars for the Company’s risk consulting and internal audit division were $232 million for the year ended December 31, 2017, up 0.2% from $231 million for the year ended December 31, 2016. As a percentage of revenues, gross margin dollars for risk consulting and internal audit services were 28.4% in 2017, down from 28.7% in 2016. The decline in 2017 gross margin percentage compared to 2016 was primarily due to slightly lower staff utilization rates.
Selling, General and Administrative Expenses. The Company’s selling, general and administrative expenses consist primarily of staff compensation, advertising, depreciation and occupancy costs. The Company’s selling, general and administrative expenses were $1.65 billion for the year ended December 31, 2017, up 2.5% from $1.61 billion for the year ended December 31, 2016. As a percentage of revenues, the Company’s selling, general and administrative expenses were 31.3% for 2017, up from 30.6% for 2016. Contributing factors for each reportable segment are discussed below in further detail.
Selling, general and administrative expenses for the Company’s temporary and consultant staffing division were $1.14 billion for the year ended December 31, 2017, up 1.9% from $1.12 billion for the year ended December 31, 2016. As a percentage of revenues, selling, general and administrative expenses for temporary and consultant staffing were 28.4% in 2017, up from 27.7% in 2016. For 2017 compared to 2016, the increase in selling, general and administrative expenses as a percentage of revenue is primarily due to increases in staff compensation costs and costs expensed related to digital technology initiatives.
Selling, general and administrative expenses for the Company’s permanent placement staffing division were $361 million for the year ended December 31, 2017, up 6.5% from $339 million for the year ended December 31, 2016. As a percentage of revenues, selling, general and administrative expenses for permanent placement staffing services were 82.1% in 2017, up from 80.7% in 2016. For 2017 compared to 2016, the increase in selling, general and administrative expenses as a percentage of revenue is primarily due to increases in staff compensation costs and costs expensed related to digital technology initiatives.
Selling, general and administrative expenses for the Company’s risk consulting and internal audit services division were $148 million for the year ended December 31, 2017, down 1.7% from $150 million for the year ended December 31, 2016. As a percentage of revenues, selling, general and administrative expenses for risk consulting and internal audit services were 18.1% in 2017, down from 18.7% in 2016. For 2017 compared to 2016, the decrease in selling, general and administrative expenses as a percentage of revenue is primarily due to decreases in fixed overhead costs.
Operating Income. The Company’s total operating income was $517 million, or 9.8% of revenues, for the year ended December 31, 2017, down 6.7% from $555 million, or 10.6% of revenues, for the year ended December 31, 2016. For the Company’s temporary and consultant staffing division, operating income was $356 million, or 8.9% of applicable revenues, down 9.7% from $394 million, or 9.8% of applicable revenues, in 2016. For the Company’s permanent placement staffing division, operating income was $77 million, or 17.7% of applicable revenues, down 2.9% from operating income of $80 million, or 19.1% of applicable revenues, in 2016. For the Company’s risk consulting and internal audit services division, operating income was $84 million, or 10.3% of applicable revenues, up 3.9% from operating income of $81 million, or 10% of applicable revenues, in 2016.
Provision for income taxes. The provision for income taxes was 43.9% and 38.0% for the years ended December 31, 2017 and 2016, respectively. The increase is primarily due to the $34 million one-time, non-cash charge resulting from the recently enacted TCJA.

Years ended December 31, 2016 and 2015
Revenues. The Company’s revenues were $5.25 billion for the year ended December 31, 2016, increasing by 3.1% compared to $5.09 billion for the year ended December 31, 2015. Revenues from foreign operations represented 20% and 19% of total revenues for the years ended December 31, 2016 and 2015, respectively. The Company analyzes its revenues for three reportable segments: temporary and consultant staffing, permanent placement staffing and risk consulting and internal audit services. In 2016, revenues for temporary and consultant staffing and risk consulting and internal audit services were up and revenue for permanent placement staffing was down compared to 2015. Revenue growth was strongest internationally, most notably within Europe. Risk consulting and internal audit services continued to post strong growth rates. Contributing factors for each reportable segment are discussed below in further detail.
Temporary and consultant staffing revenues were $4.03 billion for the year ended December 31, 2016, increasing by 2.4% compared to revenues of $3.93 billion for the year ended December 31, 2015. Key drivers of temporary and consultant staffing revenues include average hourly bill rates and the number of hours worked by the Company’s temporary employees on client engagements. On a same-day, constant-currency basis, temporary and consultant staffing revenues increased 2.8% for 2016, compared to 2015, due primarily to a 4.2% increase in average bill rates, partially offset by fewer hours worked by the Company's temporary employees. In the U.S., 2016 revenues increased 2.0% on an as reported basis and 1.9% on a same-day basis, compared to 2015. For the Company’s international operations, 2016 revenues increased 4.2% on an as reported basis and 6.9% on a same-day, constant-currency basis, compared to 2015.
Permanent placement staffing revenues were $419 million for the year ended December 31, 2016, decreasing by 0.5% compared to revenues of $421 million for the year ended December 31, 2015. Key drivers of permanent placement staffing revenues consist of the number of candidate placements and average fees earned per placement. On a same-day, constant- currency basis, permanent placement revenues increased 0.3% for 2016 compared to 2015. The decrease in as reported revenue was driven primarily by a decrease in number of placements, partially offset by an increase in average fees earned per placement. In the U.S., 2016 revenues increased 0.3% on an as reported basis and 0.1% on a same-day basis, compared to 2015. For the Company’s international operations, 2016 revenues decreased 2.3% on an as reported basis, and on a same-day, constant-currency basis increased 0.6%, compared to 2015. Historically, demand for permanent placement services is even more sensitive to economic and labor market conditions than demand for temporary and consulting staffing and this is expected to continu e.
Risk consulting and internal audit services revenues were $804 million for the year ended December 31, 2016, increasing by 8.3% compared to revenues of $743 million for the year ended December 31, 2015. Key drivers of risk consulting and internal audit services revenues are the billable hours worked by consultants on client engagements and average hourly bill rates. On a same-day, constant-currency basis, risk consulting and internal audit services revenues increased 8.5% for 2016 compared to 2015, due primarily to an increase in number of hours worked, partially offset by a decrease in average hourly bill rates. In the U.S., 2016 revenues increased 8.0% on an as reported basis, or 7.9% on a same-day basis, compared to 2015. For the Company’s international operations, 2016 revenues increased 9.6% on an as reported basis and 11.7% on a same-day, constant-currency basis, compared to 2015.

Gross Margin. The Company’s gross margin dollars were $2.16 billion for the year ended December 31, 2016, up 2.2% from $2.11 billion for the year ended December 31, 2015. Contributing factors for each reportable segment are discussed below in further detail.
G ross margin dollars from the Company’s temporary and consultant staffing division represent revenues less direct costs of services, which consist of payroll, payroll taxes and benefit costs for temporary employees, and reimbursable expenses. The key drivers of gross margin are: i) pay/bill spreads, which represent the differential between wages paid to temporary employees and amounts billed to clients; ii) fringe costs, which are primarily composed of payroll taxes and benefit costs for temporary and consultant staffing employees; and iii) conversion revenues, which are earned when a temporary position converts to a permanent position with the Company’s client. Gross margin dollars for the Company’s temporary and consultant staffing division were $1.51 billion for the year ended December 31, 2016, up 3.2% from $1.46 billion for the year ended December 31, 2015. As a percentage of revenues, gross margin dollars for temporary and consultant staffing were 37.5% in 2016, up from 37.2% in 2015. This year-over-year improvement in gross margin percentage of 0.3% was primarily attributable to higher pay/bill spreads and lower payroll taxes and workers’ compensation costs, partially offset by lower conversion revenues as a percentage of applicable revenue in 2016 compared to 2015.
G ross margin dollars from permanent placement staffing represent revenues less reimbursable expenses. Gross margin dollars for the Company’s permanent placement staffing division were $419 million for the year ended December 31, 2016, down 0.5% from $421 million for the year ended December 31, 2015. Because reimbursable expenses for permanent placement staffing services are de minimis, the decrease in gross margin dollars is substantially explained by the decrease in revenues previously discussed.
G ross margin dollars for risk consulting and internal audit services represent revenues less direct costs of services, which consist primarily of professional staff payroll, payroll taxes, benefit costs and reimbursable expenses. The primary drivers of risk consulting and internal audit services gross margin are: i) the relative composition of and number of professional staff and their respective pay and bill rates; and ii) staff utilization, which is the relationship of time spent on client engagements in proportion to the total time available for the Company’s risk consulting and internal audit services staff. Gross margin dollars for the Company’s risk consulting and internal audit division were $231 million for the year ended December 31, 2016, up 0.4% from $230 million for the year ended December 31, 2015. As a percentage of revenues, gross margin dollars for risk consulting and internal audit services were 28.7% in 2016, down from 31.0% in 2015. The decline in 2016 gross margin percentage compared to 2015 was due to lower staff utilization rates and the mix impact of lower financial services and regulatory compliance revenues, which is typically a higher margin business for the Company.
Selling, General and Administrative Expenses. T he Company’s selling, general and administrative expenses consist primarily of staff compensation, advertising, depreciation and occupancy costs. The Company’s selling, general and
21

administrative expenses were $1.61 billion for the year ended December 31, 2016, up 4.7% from $1.53 billion for the year ended December 31, 2015. As a percentage of revenues, the Company’s selling, general and administrative expenses were 30.6% for 2016, up from 30.1% for 2015. Contributing factors for each reportable segment are discussed below in further detail.
S elling, general and administrative expenses for the Company’s temporary and consultant staffing division were $1.12 billion for the year ended December 31, 2016, up 5.0% from $1.06 billion for the year ended December 31, 2015. As a percentage of revenues, selling, general and administrative expenses for temporary and consultant staffing were 27.7% in 2016, up from 27.1% in 2015. For 2016 compared to 2015, the increase in selling, general and administrative expenses as a percentage of revenue is primarily due to increases in staff compensation costs, inclusive of employee medical costs, and variable overhead, including costs related to the Company’s new CRM and project management systems.
S elling, general and administrative expenses for the Company’s permanent placement staffing division were $339 million for the year ended December 31, 2016, up 0.8% from $336 million for the year ended December 31, 2015. As a percentage of revenues, selling, general and administrative expenses for permanent placement staffing services were 80.7% in 2016, up from 79.7% in 2015. For 2016 compared to 2015, the increase in selling, general and administrative expenses as a percentage of revenue is primarily due to increases in staff compensation costs, inclusive of employee medical costs.
S elling, general and administrative expenses for the Company’s risk consulting and internal audit services division were$150 million for the year ended December 31, 2016, up 11.9% from $134 million for the year ended December 31, 2015. As a percentage of revenues, selling, general and administrative expenses for risk consulting and internal audit services were 18.7% in 2016, up from 18.1% in 2015. For 2016 compared to 2015, the increase in selling, general and administrative expenses as a percentage of revenue is primarily due to an increase in administrative compensation and fixed overhead.
Operating Income. The Company’s total operating income was $555 million, or 10.6% of revenues, for the year ended December 31, 2016, down 4.5% from $581 million, or 11.4% of revenues, for the year ended December 31, 2015. For the Company’s temporary and consultant staffing division, operating income was $394 million, or 9.8% of applicable revenues, down 1.5% from $400 million, or 10.2% of applicable revenues, in 2015. For the Company’s permanent placement staffing division, operating income was $80 million, or 19.1% of applicable revenues, down 5.9% from operating income of $85 million, or 20.2% of applicable revenues, in 2015. For the Company’s risk consulting and internal audit services division, operating income was $81 million, or 10.0% of applicable revenues, down 15.7% from operating income of $96 million, or 12.9% of applicable revenues, in 2015.
Provision for income taxes. The provision for income taxes was 38.0% and 38.4% for the years ended December 31, 2016 and 2015, respectively. The decrease is primarily due to an increase of federal and state credits in the U.S, and benefit of foreign losses.
Liquidity and Capital Resources
The change in the Company’s liquidity during the years ended December 31, 2017, 2016 and 2015, is primarily the net effect of funds generated by operations and the funds used for capital expenditures, repurchases of common stock, payment of dividends, and payments to trusts for employee deferred compensation plans.

Cash used in financing activities for the year ended December 31, 2015, was $369 million. This included repurchases of $271 million in common stock, $108 million in cash dividends to stockholders, offset by proceeds of $2 million from exercises of stock options and the excess tax benefits from stock-based compensation of $9 million.
As of December 31, 2017, the Company is authorized to repurchase, from time to time, up to 2.3 million additional shares of the Company’s common stock on the open market or in privately negotiated transactions, depending on market conditions. On February 13, 2018, the Company authorized the repurchase, from time to time, of up to an additional 10 million shares of the Company's common stock on the open market or in privately negotiated transactions, depending on market conditions. During the years ended December 31, 2017, 2016 and 2015, the Company repurchased approximately 4.0 million shares, 4.0 million shares and 4.3 million shares of common stock on the open market for a total cost of $197 million, $164 million and $228 million, respectively.

Repurchases of shares have been funded with cash generated from operations.
The Company’s working capital at December 31, 2017, included $295 million in cash and cash equivalents. The Company expects that internally generated cash will be sufficient to support the working capital needs of the Company, the Company’s fixed payments, dividends, and other obligations on both a short-term and long-term basis.
On February 13, 2018, the Company announced a quarterly dividend of $.28 per share to be paid to all shareholders of record on February 23, 2018. The dividend will be paid on March 15, 2018.

Item 7A. Quantitative and Qualitative Disclosures About Market Risk
Because a portion of the Company’s net revenues are derived from its operations outside the U.S. and are denominated in
local currencies, the Company is exposed to the impact of foreign currency fluctuations. The Company’s exposure to foreign currency exchange rates relates primarily to the Company’s foreign subsidiaries. Exchange rates impact the U.S. dollar value of the Company’s reported revenues, expenses, earnings, assets and liabilities.
For the year ended December 31, 2017, approximately 22% of the Company’s revenues were generated outside of the United States. These operations transact business in their functional currency, which is the same as their local currency. As a result, fluctuations in the value of foreign currencies against the U.S. dollar, particularly the Canadian dollar, British pound, Euro, and Australian dollar have an impact on the Company’s reported results. Under GAAP, revenues and expenses denominated in foreign currencies are translated into U.S. dollars at the monthly average exchange rates prevailing during the period. Consequently, as the value of the U.S. dollar changes relative to the currencies of the Company’s non-U.S. markets, the Company’s reported results vary.
During 2017, the U.S. dollar fluctuated, but generally weakened, against the primary currencies in which the Company conducts business. Currency exchange rates had the effect of increasing reported net service revenues by $11 million, or 0.2%, in 2017 compared to prior year. The general weakening of the U.S. dollar also affected the reported level of expenses incurred in the Company’s foreign operations. Because substantially all of the Company’s foreign operations generated revenues and incurred expenses within the same country and currency, the unfavorable effect of higher reported operating expenses largely offset the increase in reported revenues. Reported net income was $0.8 million, or 0.2%, higher in the year ended December 31, 2017 compared to prior year due to the effect of currency exchange rates.
For the month ended January 31, 2018, the U.S. dollar weakened against the Euro, British Pound, Canadian Dollar, and Australian dollar. If currency exchange rates were to remain at January 2018 levels throughout 2018, the Company’s 2018 full-year reported revenues would be impacted favorably, mostly offset by an unfavorable impact to operating expenses. Thus, the impact to reported net income would likely be immaterial.
Fluctuations in currency exchange rates impact the U.S. dollar amount of the Company’s stockholders’ equity. The assets and liabilities of the Company’s non-U.S. subsidiaries are translated into U.S. dollars at the exchange rates in effect at period end. The resulting translation adjustments are recorded in stockholders’ equity as a component of accumulated other comprehensive income. Although currency fluctuations impact the Company’s reported results and shareholders’ equity, such fluctuations generally do not affect cash flow or result in actual economic gains or losses. The Company generally has few cross-border transfers of funds, except for transfers to the U.S. for payment of intercompany loans, working capital loans made between the U.S. and the Company’s foreign subsidiaries, and dividends from the Company’s foreign subsidiaries.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
Note A—Summary of Significant Accounting Policies
Nature of Operations. Robert Half International Inc. (the “Company”) provides specialized staffing and risk consulting services through such divisions as Accountemps®, Robert Half® Finance & Accounting, OfficeTeam®, Robert Half® Technology, Robert Half® Management Resources, Robert Half® Legal, The Creative Group®, and Protiviti®. The Company, through its Accountemps, Robert Half Finance & Accounting, and Robert Half Management Resources divisions, is a specialized provider of temporary, full-time, and senior-level project professionals in the fields of accounting and finance. OfficeTeam specializes in highly skilled temporary administrative support professionals. Robert Half Technology provides project and full-time technology professionals. Robert Half Legal provides temporary, project, and full-time staffing of lawyers, paralegals and legal support personnel. The Creative Group provides interactive, design, marketing, advertising and public relations professionals. Protiviti is a global consulting firm that helps companies solve problems in finance, technology, operations, data, analytics, governance, risk and internal audit, and is a wholly owned subsidiary of the Company. Revenues are predominantly derived from specialized staffing services. The Company operates in North America, South America, Europe, Asia and Australia. The Company is a Delaware corporation.
Basis of Presentation. The Consolidated Financial Statements (“Financial Statements”) of the Company are prepared in conformity with accounting principles generally accepted in the United States of America (“GAAP”) and the rules of the Securities and Exchange Commission (“SEC”).
Principles of Consolidation. The Financial Statements include the accounts of the Company and its subsidiaries, all of which are wholly owned. All intercompany balances have been eliminated.
Use of Estimates. The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. As of December 31, 2017, such estimates included allowances for uncollectible accounts receivable, workers’ compensation losses and income and other taxes. Management estimates are also utilized in the Company’s goodwill impairment assessment and in the valuation of stock grants subject to market conditions. Actual results and outcomes may differ from management's estimates and assumptions.
Revenue Recognition. The Company derives its revenues from three segments: temporary and consultant staffing, permanent placement staffing, and risk consulting and internal audit services. Net service revenues as presented on the Consolidated Statements of Operations represent services rendered to customers less sales adjustments and allowances. Reimbursements, including those related to travel and out-of-pocket expenses, are also included in net service revenues, and equivalent amounts of reimbursable expenses are included in direct costs of services. The Company records revenue on a gross basis as a principal versus on a net basis as an agent in the presentation of revenues and expenses. The Company has concluded that gross reporting is appropriate because the Company (i) has the risk of identifying and hiring qualified employees, (ii) has the discretion to select the employees and establish their price and duties and (iii) bears the risk for services that are not fully paid for by customers.
Temporary and consultant staffing revenues—Temporary and consultant staffing revenues are recognized when the services are rendered by the Company’s temporary employees. Employees placed on temporary assignment by the Company are the Company’s legal employees while they are working on assignments. The Company pays all related costs of employment, including workers’ compensation insurance, state and federal unemployment taxes, social security and certain fringe benefits. The Company assumes the risk of acceptability of its employees to its customers.
Permanent placement staffing revenues—Permanent placement staffing revenues are recognized when employment candidates accept offers of permanent employment. The Company has a substantial history of estimating the effect of permanent placement candidates who do not remain with its clients through the 90-day guarantee period. Allowances are established to estimate these losses. Fees to clients are generally calculated as a percentage of the new employee’s annual compensation. No fees for permanent placement services are charged to employment candidates.
Risk consulting and internal audit revenues—Risk consulting and internal audit services are generally provided on a time-and-material basis or fixed-fee basis. Revenues earned under time-and-material arrangements and fixed-fee arrangements are recognized using a proportional performance method as hours are incurred relative to total estimated hours for the engagement. The Company periodically evaluates the need to provide for any losses on these projects, and losses are recognized when it is probable that a loss will be incurred.
30

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (Continued)
Costs of Services. Direct costs of temporary and consultant staffing consist of payroll, payroll taxes and benefit costs for the Company’s temporary employees, as well as reimbursable expenses. Direct costs of permanent placement staffing services consist of reimbursable expenses. Risk consulting and internal audit costs of services include professional staff payroll, payroll taxes and benefit costs, as well as reimbursable expenses.
Advertising Costs. The Company expenses all advertising costs as incurred. Advertising costs for the years ended December 31, 2017, 2016 and 2015, are reflected in the following table (in thousands):

|  | Years Ended December 31,
|  | 2017 |  | 2016 |  | 2015
Advertising Costs |  | $ | 49,433 |  |  | $ | 47,312 |  |  | $ | 44,015 |

Comprehensive Income. Comprehensive income includes net income and certain other items that are recorded directly to Stockholders’ Equity. The Company’s only source of other comprehensive income is foreign currency translation adjustments.
Fair Value of Financial Instruments. The Company does not have any financial instruments which require re-measurement to fair value. The carrying values of cash and cash equivalents, accounts receivable, accounts payable and accrued expenses represent fair value based upon their short-term nature.
Cash and Cash Equivalents. The Company considers all highly liquid investments with a maturity at the date of purchase of three months or less as cash equivalents.
Goodwill and Intangible Assets. Goodwill and intangible assets primarily consist of the cost of acquired companies in excess of the fair market value of their net tangible assets at the date of acquisition. Identifiable intangible assets are amortized over their lives, typically ranging from two to five years. Goodwill is not amortized, but is tested at least annually for impairment. The Company completed its annual goodwill impairment analysis as of June 30 in each of the three years ended December 31, 2017, and determined that no adjustment to the carrying value of goodwill was required. There were no events or changes in circumstances during the six months ended December 31, 2017 that caused the Company to perform an interim impairment assessment.
Income Tax Assets and Liabilities. In establishing its deferred income tax assets and liabilities, the Company makes judgments and interpretations based on the enacted tax laws and published tax guidance that are applicable to its operations. Deferred tax assets and liabilities are measured and recorded using current enacted tax rates, which the Company expects will apply to taxable income in the years in which those temporary differences are recovered or settled. The likelihood of a material change in the Company’s expected realization of these assets is dependent on future taxable income, its ability to use foreign tax credit carryforwards and carrybacks, final U.S. and foreign tax settlements, and the effectiveness of its tax planning strategies in the various relevant jurisdictions.
On December 22, 2017, the President signed the Tax Cuts and Jobs Act (“TCJA”) into law. Effective January 1, 2018, among other changes, TCJA reduces the federal corporate tax rate to 21 percent, provides for a deemed repatriation and taxation at reduced rates of certain foreign earnings, and establishes new mechanisms to tax certain foreign earnings going forward. Similar to other large multinational companies, TCJA has wide ranging implications for the Company. The Company has recorded provisional amounts and a reasonable estimate of TCJA’s impact on its financial statements. As guidance regarding implementation of various provisions of TCJA is released by the U.S. Government over the course of 2018, the Company’s estimates may need to be adjusted accordingly.
In December 2017, the SEC issued Staff Accounting Bulletin No. 118, Income Tax Accounting Implications of the Tax Cuts and Jobs Act (“SAB 118”), which allows the Company to record provisional amounts during a measurement period not to extend beyond one year of the enactment date. Since TCJA was passed late in the fourth quarter of 2017, and ongoing guidance and accounting interpretations are expected over the next 12 months, the Company considers the accounting of the transition tax, deferred tax remeasurements, and other items to be incomplete due to the forthcoming guidance and ongoing analysis of its final tax positions for the year ended December 31, 2017. The Company expects to complete its analysis within the measurement period in accordance with SAB 118.
31

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (Continued)
The Company also evaluates the need for valuation allowances to reduce the deferred tax assets to realizable amounts. Management evaluates all positive and negative evidence and uses judgment regarding past and future events, including operating results, to help determine when it is more likely than not that all or some portion of the deferred tax assets may not be realized. When appropriate, a valuation allowance is recorded against deferred tax assets to offset future tax benefits that may not be realized. Valuation allowances of $20.2 million and $18.9 million were recorded as of December 31, 2017 and 2016, respectively. The valuation allowances recorded related primarily to net operating losses in certain foreign operations. If such losses are ultimately utilized to offset future operating income, the Company will recognize a tax benefit up to the full amount of the valuation reserve.
Workers’ Compensation. Except for states which require participation in state-operated insurance funds, the Company retains the economic burden for the first $0.5 million per occurrence in workers’ compensation claims. Workers’ compensation includes ongoing healthcare and indemnity coverage for claims and may be paid over numerous years following the date of injury. Claims in excess of $0.5 million are insured. Workers’ compensation expense includes the insurance premiums for claims in excess of $0.5 million, claims administration fees charged by the Company’s workers’ compensation administrator, premiums paid to state-operated insurance funds, and an estimate for the Company’s liability for Incurred But Not Reported (“IBNR”) claims and for the ongoing development of existing claims.
The reserves for IBNR claims and for the ongoing development of existing claims in each reporting period includes estimates. The Company has established reserves for workers’ compensation claims using loss development rates which are estimated using periodic third party actuarial valuations based upon historical loss statistics which include the Company’s historical frequency and severity of workers’ compensation claims, and an estimate of future cost trends. While management believes that its assumptions and estimates are appropriate, significant differences in actual experience or significant changes in assumptions may materially affect the Company’s future results.
Foreign Currency Translation. The reporting currency of the Company and its subsidiaries is the U.S. dollar. The functional currency of the Company's foreign subsidiaries is their local currency. The results of operations of the Company’s foreign subsidiaries are translated at the monthly average exchange rates prevailing during the period. The financial position of the Company’s foreign subsidiaries is translated at the current exchange rates at the end of the period, and the related translation adjustments are recorded as a component of accumulated other comprehensive income within Stockholders’ Equity. Gains and losses resulting from foreign currency transactions are included as a component of selling, general and administrative expenses in the Consolidated Statements of Operations, and have not been material for all periods presented.
Stock-based Compensation. Under various stock plans, officers, employees and outside directors have received or may receive grants of restricted stock, stock units, stock appreciation rights or options to purchase common stock.
The Company recognizes compensation expense equal to the grant-date fair value for all stock-based payment awards that are expected to vest. This expense is recorded on a straight-line basis over the requisite service period of the entire award, unless the awards are subject to performance conditions, in which case the Company recognizes compensation expense over the requisite service period of each separate vesting tranche. The Company determines the grant-date fair value of its restricted stock and stock unit awards using the fair market value of its stock on the grant date, unless the awards are subject to market conditions, in which case the Company utilizes a binomial-lattice model (i.e., Monte Carlo simulation model). The Monte Carlo simulation model utilizes multiple input variables to determine the stock-based compensation expense.
No stock appreciation rights have been granted under the Company’s existing stock plans. The Company has not granted any options to purchase common stock since 2006.
Property and Equipment. Property and equipment are recorded at cost. Depreciation expense is computed using the straight-line method over the following useful lives:

Computer hardware | 2 to 3 years
Computer software | 2 to 5 years
Furniture and equipment | 5 years
Leasehold improvements | Term of lease, 5 years maximum

Internal-use Software. The Company capitalizes direct costs incurred in the development of internal-use software. Amounts capitalized are reported as a component of computer software within property and equipment. Internal-use software development costs capitalized for the years ended December 31, 2017, 2016 and 2015, are reflected in the following table (in thousands):

|  | Years Ended December 31,
|  | 2017 |  | 2016 |  | 2015
Internal-use software development costs |  | $ | 9,030 |  |  | $ | 33,753 |  |  | $ | 31,964 |

Note B—New Accounting Pronouncements
Recently Adopted Accounting Pronouncements
Stock Compensation. In March 2016, the Financial Accounting Standards Board (“FASB”) issued authoritative guidance which changes financial reporting as it relates to Employee Share-Based Payment Accounting. Under the new guidance, several aspects of the accounting for share-based payment award transactions will be simplified, including: i) income tax consequences; ii) classification of awards as either equity or liabilities; and iii) classification on the statement of cash flows. The new guidance was effective for annual and interim periods beginning after December 15, 2016 and was adopted by the Company effective January 1, 2017. The adoption of this guidance did not have a material impact on the Company’s financial statements.
Recently Issued Accounting Pronouncements Not Yet Adopted
Revenue from Contracts with Customers. In May 2014, the FASB issued authoritative guidance that provides companies with a single model for use in accounting for revenue arising from contracts with customers and supersedes current revenue recognition guidance, including industry-specific revenue guidance. The new guidance requires a company to recognize revenue to depict the transfer of goods or services to a customer at an amount that reflects the consideration it expects to receive in exchange for those goods or services. It also requires additional disclosure about the nature, amount, timing and uncertainty of revenue and cash flows arising from customer contracts, including significant judgments and changes in judgments and assets recognized from costs incurred to obtain or fulfill a contract. The guidance permits companies to either apply the requirements retrospectively to all prior periods presented, or apply the requirements in the year of adoption, through a cumulative adjustment. The amended guidance also requires additional quantitative and qualitative disclosures. In March 2016, amended guidance was issued to clarify implementation guidance on principal versus agent consideration. In April 2016 an amendment provided clarifications on determining whether a promised license provides a customer with a right to use or a right to access an entity’s intellectual property. In May 2016 an amendment provided narrow scope improvements and practical expedients to reduce the potential diversity, cost and complexity of applying new revenue standard. These amendments, as well as the original guidance, are all effective for annual and interim periods beginning after December 15, 2017. The new standard was adopted by the Company effective January 1, 2018. The standard is required to be adopted on either a full or modified retrospective basis. As the initial adoption of the standard did not have a material impact on the Company’s financial statements, prior periods will not be restated. The Company also had no significant changes to systems, processes, or controls.
Lease Accounting. In February 2016, the FASB issued authoritative guidance which changes financial reporting as it relates to leasing transactions. Under the new guidance, lessees will be required to recognize a lease liability, measured on a discounted basis; and a right-of-use asset, for the lease term. The new guidance is effective for annual and interim periods beginning after December 15, 2018. Early application is permitted for all entities upon issuance. Lessees and lessors must apply a modified retrospective transition approach for leases existing at, or entered into after, the beginning of the earliest comparative period presented in the financial statements. While the impact of the adoption of this guidance will include the recognition of right-of-use assets and lease liabilities on the Company’s statement of financial position, the Company is in the process of evaluating the impact of adoption of this guidance on its systems, processes, and controls.
33

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (Continued)
Classification of Certain Cash Receipts and Cash Payments in Statement of Cash Flows. In August 2016, the FASB issued authoritative guidance designed to address diversity in how certain cash receipts and cash payments are presented and classified in the statement of cash flows, including: i) contingent consideration payments made after a business combination; ii) proceeds from the settlement of insurance claims; and iii) proceeds from the settlement of corporate-owned life insurance policies. The new guidance is effective for the Company for fiscal years beginning after December 15, 2017, and interim periods within those fiscal years. Early adoption is permitted in any interim or annual period. The Company believes the adoption of this guidance will not have a material impact on its financial statements.
Simplifying the Test for Goodwill Impairment. In January 2017, the FASB issued authoritative guidance to simplify the goodwill impairment testing process. The new standard eliminates Step 2 of the goodwill impairment test. If a company determines in Step 1 of the goodwill impairment test that the carrying value of goodwill is greater than the fair value, an impairment in that amount should be recorded to the income statement, rather than proceeding to Step 2. The new guidance is effective for the Company beginning after December 31, 2019, although early adoption is permitted. The Company believes the adoption of this guidance will not have a material impact on its financial statements.
Stock Compensation. In May 2017, the FASB issued authoritative guidance updating which changes in the terms or conditions of a share-based payment award require an entity to apply modification accounting. Under the amended guidance, entities are required to account for the effects of a modification if the fair value, vesting conditions or classification (as an equity instrument or a liability instrument) of the modified award change from that of the original award immediately before the modification. The new guidance is effective for the Company in interim or annual periods beginning after December 15, 2017. The Company believes the adoption of this guidance will not have a material impact on its financial statements.

Note H—Income Taxes
The Company recorded provisional amounts and a reasonable estimate in its provision for income taxes and estimated deferred tax assets, for the impact of TCJA.

In accordance with TCJA, the Company remeasured certain deferred tax assets and liabilities, based on the rates at which they are expected to reverse in the future. The Company is still analyzing certain aspects of TCJA and refining our calculation, which could potentially affect the measurement of these balances or give rise to different deferred tax amounts. The provisional
36

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (Continued)
amount and reasonable estimate recorded related to the re-measurement of the Company’s deferred tax balance was $34.6 million.
The Company recorded provisional amounts and a reasonable estimate for the one-time transition tax on its total post-1986 foreign earnings and profits, as required by TCJA. A provisional amount of $7.7 million in connection with the transition tax is offset by foreign tax credits in the Company's current income tax expense. The Company anticipates additional guidance will be released by the government throughout 2018 that may require the Company to adjust this estimate during the measurement period prescribed by SAB 118. No additional income taxes have been provided for any remaining undistributed foreign earnings not subject to the transition tax, or any additional outside basis differences inherent in our foreign entities, as the Company is still in the process of evaluating its foreign cash needs, and how much, if any, of the amount of earnings should be considered indefinitely reinvested.

FASB authoritative guidance prescribes a recognition threshold and measurement attribute criteria for the financial statement recognition and measurement of a tax position taken or expected to be taken in a tax return. The literature also provides guidance on derecognition, classification, interest and penalties, accounting in interim periods, disclosure and transition.
The following table reconciles the total amounts of gross unrecognized tax benefits from January 1, 2015 to December 31, 2017 (in thousands):

Balance at end of period |  | $ | 2,886 |  |  | $ | 731 |  |  | $ | 814 |

The total amount of unrecognized tax benefits that, if recognized, would impact the effective tax rate is $2.8 million, $0.5 million and $0.5 million for 2017, 2016 and 2015, respectively.
The Company’s continuing practice is to recognize interest and penalties related to income tax matters in income tax expense. The total amount of interest and penalties accrued is $0.1 million as of December 31, 2017. The total amount of interest and penalties accrued as of December 31, 2016 is $0.1 million, including a $0.1 million reduction recorded in income tax expense during the year. The total amount of interest and penalties accrued as of December 31, 2015, was $0.2 million, including a $2.3 million reduction recorded in income tax expense during the year.
The Company believes it is reasonably possible that the settlement of certain tax uncertainties could occur within the next twelve months; accordingly, $0.1 million of the unrecognized gross tax benefit has been classified as a current liability as of December 31, 2017. This amount primarily represents unrecognized tax benefits composed of items related to assessed state income tax audits and negotiations.
The Company’s major income tax jurisdictions are the United States, Australia, Belgium, Canada, France, Germany and the United Kingdom. For U.S. federal income tax, the Company remains subject to examination for 2014 and subsequent years. For major U.S. states, with few exceptions, the Company remains subject to examination for 2013 and subsequent years. Generally, for the foreign countries, the Company remains subject to examination for 2010 and subsequent years.

On March 13, 2014, Plaintiff Leonor Rodriguez, on her own behalf and on behalf of a putative class of allegedly similarly situated individuals, filed a complaint against the Company in the Superior Court of California, San Diego County. The complaint alleges that a putative class of current and former employees of the Company working in California since March 13, 2011 were denied compensation for the time they spent interviewing with clients of the Company as well as performing

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (Continued)
activities related to the interview process. Rodriguez seeks recovery on her own behalf and on behalf of the putative class in an unspecified amount for this allegedly unpaid compensation. Rodriguez also seeks recovery of an unspecified amount for the alleged failure of the Company to provide her and the putative class with accurate wage statements. Rodriguez also seeks an unspecified amount of other damages, attorneys’ fees, and statutory penalties, including but not limited to statutory penalties on behalf of herself and other allegedly “aggrieved employees” as defined by California’s Labor Code Private Attorney General Act (“PAGA”). On October 10, 2014, the Court granted a motion by the Company to compel all of Rodriguez’s claims, except the PAGA claim, to individual arbitration. At this stage of the litigation, it is not feasible to predict the outcome of or a range of loss, should a loss occur, from this proceeding and, accordingly, no amounts have been provided in the Company’s Financial Statements. The Company believes it has meritorious defenses to the allegations and the Company intends to continue to vigorously defend against the litigation.
On March 23, 2015, Plaintiff Jessica Gentry, on her own behalf and on behalf of a putative class of allegedly similarly situated individuals, filed a complaint against the Company in the Superior Court of California, San Francisco County, which was subsequently amended on October 23, 2015. The complaint, which was filed by the same plaintiffs’ law firm that brought the Rodriguez matter described above, alleges claims similar to those alleged in Rodriguez. Specifically, the complaint alleges that a putative class of current and former employees of the Company working in California since March 13, 2010 were denied compensation for the time they spent interviewing “for temporary and permanent employment opportunities” as well as performing activities related to the interview process. Gentry seeks recovery on her own behalf and on behalf of the putative class in an unspecified amount for this allegedly unpaid compensation. Gentry also seeks recovery of an unspecified amount for the alleged failure of the Company to provide her and the putative class with accurate wage statements. Gentry also seeks an unspecified amount of other damages, attorneys’ fees, and statutory penalties, including penalties for allegedly not paying all wages due upon separation to former employees and statutory penalties on behalf of herself and other allegedly “aggrieved employees” as defined by PAGA. On January 4, 2016, the Court denied a motion by the Company to compel all of Gentry’s claims, except the PAGA claim, to individual arbitration. At this stage of the litigation, it is not feasible to predict the outcome of or a range of loss, should a loss occur, from this proceeding and, accordingly, no amounts have been provided in the Company’s Financial Statements. The Company believes it has meritorious defenses to the allegations and the Company intends to continue to vigorously defend against the litigation.
The Company is involved in a number of other lawsuits arising in the ordinary course of business. While management does not expect any of these other matters to have a material adverse effect on the Company’s results of operations, financial position or cash flows, litigation is subject to certain inherent uncertainties.
Legal costs associated with the resolution of claims, lawsuits and other contingencies are expensed as incurred.
Note J—Stockholders’ Equity
Stock Repurchase Program. As of December 31, 2017, the Company is authorized to repurchase, from time to time, up to 2.3 million additional shares of the Company’s common stock on the open market or in privately negotiated transactions, depending on market conditions. The number and the cost of common stock shares repurchased during the years ended December 31, 2017, 2016 and 2015, are reflected in the following table (in thousands):

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (Continued)
The repurchased shares are held in treasury and are presented as if constructively retired. Treasury stock is accounted for using the cost method. Treasury stock activity for each of the three years ended December 31, 2017, 2016 and 2015 (consisting of stock option exercises and the purchase of shares for the treasury) is presented in the Consolidated Statements of Stockholders’ Equity.
Cash Dividends. The Company’s Board of Directors may at their discretion declare and pay dividends upon the shares of the Company’s stock either out of the Company’s retained earnings or capital surplus. The cash dividends declared during the years ended December 31, 2017, 2016 and 2015, are reflected in the following table:

|  | Years Ended December 31,
|  | 2017 |  | 2016 |  | 2015
Cash dividends declared per share |  | $ | .96 |  |  | $ | .88 |  |  | $ | .80 |

Repurchases of shares and issuances of cash dividends are applied first to the extent of retained earnings and any remaining amounts are applied to capital surplus.
Note K—Stock Plans
Under various stock plans, officers, employees, and outside directors have received or may receive grants of restricted stock, stock units, stock appreciation rights or options to purchase common stock. Grants have been made at the discretion of the Committees of the Board of Directors. Grants generally vest either on a straight-line basis over four years or on a cliff basis over three years. Shares offered under the plan are authorized but unissued shares or treasury shares.
Recipients of restricted stock do not pay any cash consideration to the Company for the shares, have the right to vote all shares subject to such grant, and there were no grants outstanding that received dividends prior to vesting. Restricted stock grants made on or after July 28, 2009, contain forfeitable rights to dividends. Dividends for these grants are accrued on the dividend payment dates but are not paid until the shares vest, and dividends accrued for shares that ultimately do not vest are forfeited. Recipients of stock units do not pay any cash consideration for the units, do not have the right to vote, and do not receive dividends with respect to such units.
The Company recognizes compensation expense equal to the grant-date fair value for all stock-based payment awards that are expected to vest. This expense is recorded on a straight-line basis over the requisite service period of the entire award, unless the awards are subject to performance conditions, in which case the Company recognizes compensation expense over the requisite service period of each separate vesting tranche. The Company determines the grant-date fair value of its restricted stock and stock unit awards using the fair market value on the grant date, unless the awards are subject to market conditions, in which case the Company utilizes a binomial-lattice model (i.e., Monte Carlo simulation model). The Monte Carlo simulation model utilizes multiple input variables to determine the stock-based compensation expense.
During the year ended December 31, 2017, the Company granted performance shares to its executives in the form of restricted stock. The shares granted contain (1) a performance condition based earnings per share, and (2) a performance condition based on Return on Invested Capital (“ROIC”). The ROIC performance condition measures the Company’s performance against a peer group. Shares will be delivered at the end of the three year vesting and ROIC performance period based on the Company’s actual performance compared to the peer group. Actual shares earned will range from seventy-five percent (75%) to one hundred twenty-five percent (125%) of the target award after any adjustment made for the EPS performance condition.
Stock-based compensation expense consisted of the following (in thousands):

|  | Years Ended December 31,
|  | 2017 |  | 2016 |  | 2015

Potential common shares include the dilutive effect of stock options, unvested performance-based restricted stock, restricted stock which contains forfeitable rights to dividends, and stock units.
Employee stock options will have a dilutive effect under the treasury method only when the respective period’s average market value of the Company’s common stock exceeds the exercise proceeds. Under the treasury method, exercise proceeds include the amount the employee must pay for exercising stock options, the amount of compensation cost for future service that the Company has not yet recognized, and the amount of tax benefits that would be recorded in capital surplus, if the options were exercised and the stock units and performance-based restricted stock had vested.
Note M—Business Segments
The Company, which aggregates its operating segments based on the nature of services, has three reportable segments: temporary and consultant staffing, permanent placement staffing, and risk consulting and internal audit services. The temporary and consultant staffing segment provides specialized staffing in the accounting and finance, administrative and office, information technology, legal, advertising, marketing and web design fields. The permanent placement staffing segment provides full-time personnel in the accounting, finance, administrative and office, and information technology fields. The risk consulting segment provides business and technology risk consulting and internal audit services.
The accounting policies of the segments are set forth in Note A—Summary of Significant Accounting Policies. The Company evaluates performance based on income from operations before net interest income, intangible amortization expense, and income taxes.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM
To the Board of Directors and Stockholders of Robert Half International Inc.
Opinions on the Financial Statements and Internal Control over Financial Reporting
We have audited the consolidated financial statements, including the related notes, as listed in the index appearing under Item 15(a)(1), and the financial statement schedule listed in the index appearing under Item 15(a)(2), of Robert Half International Inc. and its subsidiaries (collectively referred to as the “consolidated financial statements”). We also have audited the Company’s internal control over financial reporting as of December 31, 2017 based on criteria established in Internal Control - Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO).
In our opinion, the consolidated financial statements referred to above present fairly, in all material respects, the financial position of the Company as of December 31, 2017 and 2016, and the results of their operations and their cash flows for each of the three years in the period ended December 31, 2017 in conformity with accounting principles generally accepted in the United States of America. Also in our opinion, the Company maintained, in all material respects, effective internal control over financial reporting as of December 31, 2017, based on criteria established in Internal Control - Integrated Framework (2013) issued by the COSO.
Basis for Opinions
The Company’s management is responsible for these consolidated financial statements, for maintaining effective internal control over financial reporting, and for its assessment of the effectiveness of internal control over financial reporting, included in Management’s Report on Internal Control over Financial Reporting appearing under Item 9A. Our responsibility is to express opinions on the Company’s consolidated financial statements and on the Company’s internal control over financial reporting based on our audits. We are a public accounting firm registered with the Public Company Accounting Oversight Board (United States) (“PCAOB”) and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.
We conducted our audits in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audits to obtain reasonable assurance about whether the consolidated financial statements are free of material misstatement, whether due to error or fraud, and whether effective internal control over financial reporting was maintained in all material respects.
Our audits of the consolidated financial statements included performing procedures to assess the risks of material misstatement of the consolidated financial statements, whether due to error or fraud, and performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the consolidated financial statements. Our audits also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the consolidated financial statements. Our audit of internal control over financial reporting included obtaining an understanding of internal control over financial reporting, assessing the risk that a material weakness exists, and testing and evaluating the design and operating effectiveness of internal control based on the assessed risk. Our audits also included performing such other procedures as we considered necessary in the circumstances. We believe that our audits provide a reasonable basis for our opinions.
Definition and Limitations of Internal Control over Financial Reporting
A company’s internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. A company’s internal control over financial reporting includes those policies and procedures that (i) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the company; (ii) 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 (iii) 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.
45

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.

Item 9. Changes in and Disagreements with Accountants on Accounting and Financial Disclosure
None.
Item 9A. Controls and Procedures
Disclosure Controls and Procedures. Management, including the Company’s Chairman and Chief Executive Officer and the Vice Chairman and Chief Financial Officer, evaluated the effectiveness of the design and operation of the Company’s disclosure controls and procedures as of the end of the period covered by this report. Based upon that evaluation, the Chairman and Chief Executive Officer and the Vice Chairman and Chief Financial Officer concluded that the disclosure controls and procedures were effective to ensure that information required to be disclosed in the reports the Company files and submits under the Exchange Act is recorded, processed, summarized and reported within the time periods specified in the rules and forms of the Securities and Exchange Commission and that information required to be disclosed by the Company in the reports that it files or submits under the Exchange Act is accumulated and communicated to the Company’s management, including its principal executive and principal financial officers, as appropriate to allow timely decisions regarding required disclosure.
Changes in Internal Control over Financial Reporting. There have been no changes in the Company’s internal controls over financial reporting identified in connection with the evaluation required by Rule 13a-15 of the Securities Exchange Act of 1934 that occurred during the Company’s fourth quarter that has materially affected, or is reasonably likely to materially affect, the Company’s internal control over financial reporting.
Management’s Report on Internal Control over Financial Reporting. Management is responsible for establishing and maintaining adequate internal control over financial reporting (as defined in Rule 13a-15(f) under the Securities Exchange Act of 1934, as amended). Management assessed the effectiveness of the Company’s internal control over financial reporting as of December 31, 2017, using criteria established in Internal Control-Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO) and concluded that the Company maintained effective internal control over financial reporting as of December 31, 2017.
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 and procedures may deteriorate.
The effectiveness of the Company’s internal control over financial reporting as of December 31, 2017, has been audited by PricewaterhouseCoopers LLP, an independent registered public accounting firm, as stated in their report which is included herein.
Item 9B. Other Information
On February 13, 2018, the Board of Directors amended and restated the Company’s By-Laws to implement proxy access and to update the notice, procedural, disclosure and other requirements for stockholder nominations and proposals of business not intended to be included in the Company’s proxy statement for an annual meeting of stockholders. In particular, the By-Laws were amended to include a new Article II, Section 9(a)(3), which permits a stockholder or group of up to 20 stockholders owning 3% or more of the Company’s common stock continuously for at least three years to nominate for election to the Board, and include in the Company’s proxy materials for its annual meeting of stockholders, nominees representing 25% of the number of directors then serving on the Board (rounding down to the closest whole number), subject to certain limitations and provided that such nominating stockholder(s) and nominee(s) satisfy the applicable requirements specified in the By-Laws. In connection with the Company’s adoption of proxy access and in order to ensure full disclosure for all director nominations and proposals, the Company’s By-Laws were also amended to require any notice provided pursuant to Article II, Section 9(a)(2) (the Company’s traditional advance notice provision) to disclose additional information regarding each person proposed for nomination for election as a director, the stockholder giving the notice, and the beneficial owner, if any, on whose behalf the nomination or proposal is made, including disclosure of securities ownership, derivative and short positions and certain interests, as well as to make other non-substantive changes.
The foregoing description is qualified in its entirety by reference to the Amended and Restated By-Laws that are attached hereto as Exhibit 3.2 and incorporated herein by reference.

On February 13, 2018, the Company authorized the repurchase, from time to time, of up to an additional 10 million shares of the Company's common stock on the open market or in privately negotiated transactions, depending on market conditions.
