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 advertising, marketing, and web design 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 work loads for accounting, tax and finance 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 word processors to office managers. OfficeTeam operates in much the same fashion as the Accountemps division.

1

Robert Half Finance & Accounting

The Company’s Robert Half Finance & Accounting division specializes in the placement of full-time accounting, financial, tax and banking personnel. Fees for successful 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 and placing full-time employees in areas ranging from multiple platform systems integration to end-user support, including specialists in web development, networking, application development, systems integration, database design, security and business continuity, and desktop support.

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 workload periods) are similar to the demands of the clients of the Accountemps division.

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, and senior financial analysts, for such tasks as financial systems conversions, expansion into new markets, business process reengineering and post-merger financial consolidation.

The Creative Group

The Creative Group division commenced operations in 1999 and serves clients in the areas of advertising, marketing and web design and places project consultants in a variety of positions such as creative directors, graphics designers, web content developers, web designers, media buyers, and public relations specialists.

Protiviti

Protiviti is a global business consulting and internal audit firm composed of experts specializing in risk, advisory and transactional services. The firm helps clients solve problems in finance and transactions, operations, technology, litigation, governance, risk and compliance.

Marketing and Recruiting

The Company markets its staffing services to clients as well as employment candidates. Local marketing and recruiting are generally conducted by each office or related group of offices. Local advertising directed to clients and employment candidates consists of radio, websites, social media, job banks and trade shows. Direct marketing through e-mail, regular mail and telephone solicitation also constitutes a significant portion of the Company’s total advertising. National advertising conducted by the Company consists primarily of radio, outdoor/billboard, digital and print advertisements in national newspapers, magazines, websites, social media sites and trade journals. Additionally, the Company has expanded its use of job boards in all aspects of sales and recruitment. Joint marketing arrangements have been entered into with major software manufacturers and typically provide for development of proprietary skills tests, cooperative advertising, joint mailings and similar promotional activities. The Company also actively seeks endorsements and affiliations with professional organizations in the business management, office administration and professional secretarial 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 thought leadership via print, video, corporate-maintained social media sites and other online properties. Local employees are encouraged to be active in civic organizations and industry trade groups.

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, 2013, the Company conducted its staffing services operations through 345 offices in 42 states, the District of Columbia and 18 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, 2013, Protiviti had 59 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.

3

Employees

The Company has approximately 13,000 full-time employees, including approximately 2,700 engaged directly in Protiviti operations. In addition, the Company placed approximately 197,000 temporary employees on assignments with clients during 2013. 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 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.

Available Information

The Company’s Internet address is www.roberthalf.com. The Company makes available, free of charge, through its website, its Annual Reports on Form 10-K, proxy statements for its annual meetings of stockholders, its Quarterly Reports on Form 10-Q, and Current Reports on Form 8-K, and any amendments to those reports, as soon as is reasonably practicable after such reports are filed with or furnished to the Securities and Exchange Commission.

The Company’s Code of Business Conduct and Ethics is the Code of Ethics required by Item 406 of Securities and Exchange Commission Regulation S-K. The Company intends to satisfy any disclosure obligations under Item 5.05 of Form 8-K regarding any amendment or waiver relating to its Code of Business Conduct and Ethics by posting such information on its website.

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:

The global economic crisis may continue to harm the Company’s business and financial condition. The world economy may continue in a prolonged economic downturn characterized by high unemployment, limited availability of credit and decreased consumer and business spending. Given the nature of the Company’s business, financial results could be significantly harmed should such a prolonged downturn occur. In the past, the Company’s business has suffered during periods of high unemployment as demand for staffing services tends to significantly decrease during such periods. This impact on the Company’s business could be further dramatized given the unprecedented impact it has had and may continue to have on the global labor markets.

4

Any reduction in global economic activity may harm the C ompany’s business. 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. Any variation in the economic condition or unemployment 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.

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. 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 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 alleging various wage and hour related claims 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. 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 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. An unfavorable outcome with respect to these lawsuits and any future lawsuits 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. 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. The European market has been experiencing on-going economic uncertainty which has adversely affected, and may continue to adversely affect, the Company’s operations in Europe. To the extent that these adverse economic conditions in Europe continue or 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 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. Any shortage of candidates could materially adversely affect the Company.

5

The Company o perates 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. 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 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 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. 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.

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 (collectively, the “Health Care Reform Laws”) were signed into law in the United States. The Health Care Reform Laws include a large number of health-related provisions, including requiring most individuals to have health insurance and establishing new regulations on health plans. Although the Health Care Reform Laws do not mandate that employers offer health insurance, beginning in 2015 penalties will be assessed on large employers who do not offer health insurance that meets certain affordability or benefit requirements. Providing such additional health insurance benefits to the Company’s employees, or the payment of penalties if such coverage is not provided, will increase the Company’s expense. If the Company is unable to raise the rates it charges its clients to cover this expense, such increases in expense could harm the Company’s financial results.

6

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. 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.

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 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 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. This or other similar delays or modifications of the Sarbanes Oxley 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.

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 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.

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 2. Properties

The Company’s headquarters operations are located in Menlo Park and San Ramon, California. As of December 31, 2013, placement activities were conducted through 345 offices located in the United States, Canada, the United Kingdom, Belgium, Brazil, France, the Netherlands, Germany, Italy, Luxembourg, Switzerland, Japan, China, Singapore, Australia, New Zealand, Austria, the United Arab Emirates, and Chile. As of December 31, 2013, Protiviti had 59 offices in the United States, Canada, Australia, China, France, Germany, Italy, the Netherlands, Japan, Singapore, India and the United Kingdom. All of the offices are leased.

Item 3. Legal Proceedings

On April 23, 2010, Plaintiffs David Opalinski and James McCabe, on behalf of themselves and a putative class of similarly situated Staffing Managers, filed a Complaint in the United States District Court for the District of New Jersey naming the Company and one of its subsidiaries as Defendants. The Complaint alleges that salaried Staffing Managers located throughout the U.S. have been misclassified as exempt from the Fair Labor Standards Act’s overtime pay requirements. Plaintiffs seek an unspecified amount for unpaid overtime on behalf of themselves and the class they purport to represent. Plaintiffs also seek an unspecified amount for statutory penalties, attorneys’ fees and other damages. On October 6, 2011, the Court granted the Company’s motion to compel arbitration of the Plaintiffs’ allegations. At this stage, it is not feasible to predict the outcome of or a range of loss, should a loss occur, from these allegations 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 allegations.

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 business, financial condition or results of operations, litigation is subject to certain inherent uncertainties.

Item 4. Mine Safety Disclosure

Stock Performance Graph

The following graph compares, through December 31, 2013, the cumulative total return of the Company’s Common Stock, an index of certain publicly traded employment services companies, and the S&P 500. The graph assumes the investment of $100 at the beginning of the period depicted in the chart and reinvestment of all dividends. The information presented in the graph was obtained by the Company from outside sources it considers to be reliable but has not been independently verified by the Company.

Previously, the peer group for this graph included SFN Group Inc. During the five-year period, SFN Group was acquired by Randstad Holdings N.V. in an all cash transaction. The Company and all of the other members of the peer group are based in the U.S. and traded on either the New York Stock Exchange (“NYSE”) or NASDAQ. Randstad is based in Europe and is not traded on either the NYSE or NASDAQ. Accordingly, the Company believes it is appropriate to adjust its peer group to not include Randstad and to add two other companies that provide professional staffing services (Kforce Inc. and Resources Connection Inc.) that are based in the U.S. and traded on either the NYSE or NASDAQ. The accompanying chart shows the performance of both the new peer group and the old peer group (with SFN Group being included for the period prior to its acquisition and Randstad being included for the period subsequent to its acquisition of SFN Group).

| (a) | This index represents the cumulative total return of the Company and the following corporations providing temporary or permanent employment services: CDI Corp.; Kelly Services, Inc.; Kforce Inc.; ManpowerGroup; and Resources Connection Inc.

| (b) | This index represents the cumulative total return of the Company and the following corporations providing temporary or permanent employment services: CDI Corp.; Kelly Services, Inc.; ManpowerGroup; and SFN Group Inc./Randstad Holdings NV. Effective September 2, 2011, SFN Group Inc. was acquired by Netherlands-based Randstad Holdings NV. Accordingly, this index reflects the performance of SFN Group prior to such acquisition and the performance of Randstad Holdings thereafter.

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: 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 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.”

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 4.7% and 4.6% as of December 31, 2013 and 2012, respectively. As of December 31, 2013, 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 $1.4 million. Although future results cannot always be predicted by

12

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.

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 $37.0 million and $39.3 million were recorded as of December 31, 2013 and 2012, 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 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, 2013, 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, 2013 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, 2013, of $127.4 million, $26.6 million, $0.0 million, $7.2 million, $0.0 million and $39.6 million, respectively, totaling $200.8 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, 2013.

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

13

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 last assessment would continue for all reporting units through 2013, 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 2015 and beyond, used a 5% growth factor to calculate the terminal value at the end of ten years for each unit. This rate is comparable to the Company’s most recent ten-year annual compound revenue growth rate. In its most recent calculation, the Company used a 10.5% discount rate, which is slightly higher than the 10.0% discount rate used for the Company’s test during the second quarter of 2012. This increase in discount rate is attributable primarily to an increase in the risk free rate, partially offset by a decrease in the equity market risk premium.

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 70% 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 $7.0 million, $10.9 million and $7.9 million, representing 0.22%, 0.36% and 0.30% of applicable U.S. revenue for the years ended December 31, 2013, 2012 and 2011, 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, 2013, 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.

14

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. For grants with market conditions made in the year ended December 31, 2013, the Company utilized an historical volatility of 32.23%, a 0% dividend yield and a risk-free interest rate of 0.36%. The historical volatility was based on the most recent 2.61-year period for the Company and the components of the peer group. The stock price projection for the Company and the components of the peer group assumes a 0% dividend yield. This is mathematically equivalent to reinvesting dividends in the issuing entity over the performance period. The risk-free interest rate is equal to the yield, as of the measurement date, of the zero-coupon U.S. Treasury bill that is commensurate with the remaining performance measurement period.

No stock appreciation rights have been granted under the Company’s existing stock plans.

The Company determines the fair value of options to purchase common stock using the Black-Scholes valuation model. The Company recognizes expense over the service period for options that are expected to vest and records adjustments to compensation expense at the end of the service period if actual forfeitures differ from original estimates. The Company has not granted any options to purchase common stock since 2006. There was no compensation expense related to stock options for the years ended December 31, 2013, 2012 and 2011.

For the years ended December 31, 2013, 2012 and 2011, compensation expense related to restricted stock and stock units was $38.9 million, $41.5 million and $50.9 million, respectively, of which $9.9 million, $11.4 million and $13.3 million was related to grants made in 2013, 2012 and 2011, respectively. A one-percentage point deviation in the estimated forfeiture rates would have resulted in a $0.4 million, $0.4 million and $0.5 million increase or decrease in compensation expense related to restricted stock and stock units for each year ended December 31, 2013, 2012 and 2011, respectively.

Recent Accounting Pronouncements

See Note B—“New Accounting Pronouncements” to the Company’s Consolidated Financial Statements included under Part II—Item 8 of this report.

Results of Operations

Demand for the Company’s temporary and permanent staffing services 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 were positively impacted by improving global economic conditions during 2013. Because of the inherent difficulty in predicting economic trends and the absence of material long-term contracts in any of our business units, future demand for the Company’s services cannot be forecasted with certainty. We expect total Company results to continue to be impacted by general macroeconomic conditions in 2014.

The Company’s temporary and permanent staffing services business has 345 offices in 42 states, the District of Columbia and 18 foreign countries, while Protiviti has 59 offices in 23 states and 11 foreign countries.

Because fluctuations in foreign currency exchange rates have an impact on the Company’s results, the Company provides selected growth percentages below on a constant-currency basis. Constant-currency percentages are calculated using as-reported amounts which have been retranslated using foreign currency exchange rates from the prior year’s comparable period.

15

Non-GAAP Financial Measures

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 temporary and consultant staffing and permanent placement staffing 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 staffing 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.

Years ended December 31, 2013 and 2012

Revenues. The Company’s revenues were $4.25 billion for the year ended December 31, 2013, increasing by 3.3% compared to $4.11 billion for the year ended December 31, 2012. Revenues from foreign operations represented 24% and 26% of total revenues for the years ended December 31, 2013 and 2012, 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 2013, revenues for all three of the Company’s reportable segments were up compared to 2012. Results were strongest domestically, with growth rates outside the United States impacted by weaker economies in several countries, most notably within Europe. Contributing factors for each reportable segment are discussed below in further detail.

Temporary and consultant staffing services revenues were $3.37 billion for the year ended December 31, 2013, increasing by 1.4% compared to revenues of $3.32 billion for the year ended December 31, 2012. On a same-day, constant-currency basis, temporary and consultant staffing services revenues increased 1.6% for 2013 compared to 2012. In the U.S., 2013 revenues increased 4.1%, or 4.3% on a same-day basis, compared to 2012. For the Company’s international operations, 2013 revenues decreased 6.7% and on a same-day, constant-currency basis decreased 6.5%, compared to 2012.

Permanent placement staffing revenues were $348 million for the year ended December 31, 2013, increasing by 4.0% compared to revenues of $334 million for the year ended December 31, 2012. On a same-day, constant-currency basis, permanent placement revenues increased 5.1% for 2013 compared to 2012. In the

16

U.S., 2013 revenues increased 12.5%, or 12.7% on a same-day basis, compared to 2012. For the Company’s international operations, 2013 revenues decreased 7.5%, and on a same-day, constant-currency basis decreased 5.3%, compared to 2012. Historically, demand for permanent placement services is even more sensitive to economic and labor market conditions than demand for temporary and consulting staffing services and this is expected to continue.

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, 2013, is presented in the following table:

|  | Global |  |  | United States |  |  | International |

Risk consulting and internal audit services revenues were $528 million for the year ended December 31, 2013, increasing by 16.7% compared to revenues of $453 million for the year ended December 31, 2012. Contributing to the increase was higher demand in the U.S. In the U.S., 2013 revenues increased 20.5% compared to 2012. For the Company’s international operations, 2013 revenues increased 4.2% compared to 2012.

Gross Margin. The Company’s gross margin dollars were $1.72 billion for the year ended December 31, 2013, up 4.5% from $1.65 billion for the year ended December 31, 2012. For 2013 compared to 2012, gross margin dollars for all three of the Company’s reportable segments increased. Gross margin dollars as a percentage of revenues increased for both the Company’s temporary and consultant staffing services segment and the risk consulting and internal audit services segment on a year-over-year basis. Contributing factors for each reportable segment are discussed below in further detail.

Gross margin dollars from the Company’s temporary and consultant staffing services represent revenues less direct costs of services, which consist of payroll, payroll taxes and insurance costs for temporary employees, and reimbursable expenses. Gross margin dollars for the Company’s temporary and consultant staffing services division were $1.22 billion for the year ended December 31, 2013, up 1.9% from $1.20 billion for the year ended December 31, 2012. As a percentage of revenues, gross margin dollars for temporary and consultant staffing services were 36.2% in 2013, up from 36.0% in 2012.

Gross margin dollars from permanent placement staffing services represent revenues less reimbursable expenses. Gross margin dollars for the Company’s permanent placement staffing division were $348 million for the year ended December 31, 2013, up 4.1% from $334 million for the year ended December 31, 2012. 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, insurance costs and reimbursable expenses. Gross margin dollars for the Company’s risk consulting and internal audit division were $155 million for the year ended December 31, 2013, up 32% from $117 million for the year ended December 31, 2012. As a percentage of revenues, gross margin dollars for risk consulting and internal audit services were 29.3% in 2013,

17

up from 25.9% in 2012. The increase in 2013 gross margin percentage was primarily the result of higher staff utilization rates. Utilization is the relationship of the time spent on client engagements to the total time available for the Company’s risk consulting and internal audit services staff.

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 $1.32 billion for the year ended December 31, 2013, up 1.5% from $1.31 billion for the year ended December 31, 2012. As a percentage of revenues, the Company’s selling, general and administrative expenses were 31.2% for 2013, down from 31.8% for 2012. For 2013 compared to 2012, selling, general and administrative expenses decreased for the Company’s temporary and consultant segment and increased for the Company’s permanent placement staffing services and risk consulting and internal audit services segments. Selling, general and administrative expenses as a percentage of revenues decreased for the Company’s temporary and consultant and risk consulting and internal audit services segments and increased for the Company’s permanent placement staffing services segment in 2013 compared to 2012. 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 services division were $920 million for the year ended December 31, 2013, down 0.2% from $921 million for the year ended December 31, 2012. As a percentage of revenues, selling, general and administrative expenses for temporary and consultant staffing services were 27.3% in 2013, down from 27.7% in 2012. For 2013 compared to 2012, the decrease in selling, general and administrative expenses as a percentage of revenue is primarily due to a $19 million, or 0.6% of revenues, charge in 2012 related to a litigation settlement disclosed in the Company’s July 5, 2012, Form 8-K.

Selling, general and administrative expenses for the Company’s permanent placement staffing division were $293 million for the year ended December 31, 2013, up 5.4% from $278 million for the year ended December 31, 2012. As a percentage of revenues, selling, general and administrative expenses for permanent placement staffing services were 84.3% in 2013, up from 83.3% in 2012. For 2013 compared to 2012, increases in field compensation and variable overhead, partially offset by decreases in advertising expenses and fixed overhead, drove the overall increase as a percentage of revenues.

Selling, general and administrative expenses for the Company’s risk consulting and internal audit services division were $112 million for the year ended December 31, 2013, up 5.3% from $106 million for the year ended December 31, 2012. As a percentage of revenues, selling, general and administrative expenses for risk consulting and internal audit services were 21.2% in 2013, down from 23.5% in 2012. For 2013 compared to 2012, improved leverage in general and administrative expenses, as a result of higher revenue, drove the overall decrease as a percentage of revenues.

Operating Income. The Company’s total operating income was $398 million, or 9.4% of revenues, for the year ended December 31, 2013, up 16.0% from $343 million, or 8.4% of revenues, for the year ended December 31, 2012. For the Company’s temporary and consultant staffing services division, operating income was $301 million, or 8.9% of applicable revenues, up 8.8% from $277 million, or 8.3% of applicable revenues, in 2012. For the Company’s permanent placement staffing division, operating income was $54 million, or 15.6% of applicable revenues, down 2.4% from operating income of $55 million, or 16.7% of applicable revenues, in 2012. For the Company’s risk consulting and internal audit services division, operating income was $43 million, or 8.1% of applicable revenues, up 292.7% from operating income of $11 million, or 2.4% of applicable revenues, in 2012.

Provision for income taxes. The provision for income taxes was 36.6% and 39.0% for the years ended December 31, 2013 and 2012, respectively. The 2013 decrease is primarily due to foreign restructuring, improving foreign results, and increased federal tax credits.

Years ended December 31, 2012 and 2011

Revenues. The Company’s revenues were $4.11 billion for the year ended December 31, 2012, increasing by 9% compared to $3.78 billion for the year ended December 31, 2011. Revenues from foreign operations represented 26% and 30% of total revenues for the year ended December 31, 2012 and 2011, 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 2012, revenues for all three of the Company’s reportable segments were up compared to 2011. Results were strongest domestically, with growth rates outside the United States impacted by weaker economies in several countries, most notably within Europe. Contributing factors for each reportable segment are discussed below in further detail.

Temporary and consultant staffing services revenues were $3.32 billion for the year ended December 31, 2012, increasing by 9.0% compared to revenues of $3.05 billion for the year ended December 31, 2011. On a same-day, constant-currency basis, temporary and consultant staffing services revenues increased 10.0% for 2012 compared to 2011. In the U.S., 2012 revenues increased 13.7%, or 13.5% on a same-day basis, compared to 2011. For the Company’s international operations, 2012 revenues decreased 3.0% and on a same-day, constant-currency basis increased 1.3%, compared to 2011.

Permanent placement staffing revenues were $334 million for the year ended December 31, 2012, increasing by 10.6% compared to revenues of $302 million for the year ended December 31, 2011. On a same-day, constant- currency basis, permanent placement revenues increased 12.6% for 2012 compared to 2011. In the U.S., 2012 revenues increased 20.5%, or 20.2% on a same-day basis, compared to 2011. For the Company’s international operations, 2012 revenues decreased 0.6%, and on a same-day, constant-currency basis increased 4.1%, compared to 2011. Historically, demand for permanent placement services is even more sensitive to economic and labor market conditions than demand for temporary and consulting staffing services and this is expected to continue.

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, 2012, is presented in the following table:

Risk consulting and internal audit services revenues were $453 million for the year ended December 31, 2012, increasing by 6.8% compared to revenues of $424 million for the year ended December 31, 2011. Contributing to the increase was higher demand in the U.S. In the U.S., 2012 revenues increased 11% compared to 2011. For the Company’s international operations, 2012 revenues decreased 5% compared to 2011.

Gross Margin. The Company’s gross margin dollars were $1.65 billion for the year ended December 31, 2012, up 11% from $1.49 billion for the year ended December 31, 2011. For 2012 compared to 2011, gross margin dollars for all three of the Company’s reportable segments increased. Gross margin dollars as a percentage of revenues increased for the Company’s temporary and consultant staffing services segment and

19

decreased for the Company’s risk consulting and internal audit services segment on a year-over-year basis. Contributing factors for each reportable segment are discussed below in further detail.

Gross margin dollars from the Company’s temporary and consultant staffing services represent revenues less direct costs of services, which consist of payroll, payroll taxes and insurance costs for temporary employees, and reimbursable expenses. Gross margin dollars for the Company’s temporary and consultant staffing services division were $1.20 billion for the year ended December 31, 2012, up 12% from $1.07 billion for the year ended December 31, 2011.

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, insurance costs and reimbursable expenses. Gross margin dollars for the Company’s risk consulting and internal audit division were $117 million for the year ended December 31, 2012, up 3% from $114 million for the year ended December 31, 2011. As a percentage of revenues, gross margin dollars for risk consulting and internal audit services were 25.9% in 2012, down from 26.8% in 2011. Lower gross margin percentages in the Company’s international operations contributed to the decrease in 2012 gross margin percentage.

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 $1.31 billion for the year ended December 31, 2012, up 5% from $1.24 billion for the year ended December 31, 2011.

As a percentage of revenues, selling, general and administrative expenses for temporary and consultant staffing services were 27.7% in 2012, down from 28.3% in 2011. For 2012 compared to 2011, the decrease in selling, general and administrative expenses as a percentage of revenue is primarily due to the higher operating leverage obtained by higher revenues, partially offset by a $19 million, or 0.6% of revenues, charge related to a litigation settlement disclosed in the Company’s July 5, 2012, Form 8-K.

Selling, general and administrative expenses for the Company’s permanent placement staffing division were $278 million for the year ended December 31, 2012, up 4% from $267 million for the year ended December 31, 2011.

For the Company’s risk consulting and internal audit services division, operating income was $11 million, or 2.4% of applicable revenues, up 119% from operating income of $5 million, or 1.2% of applicable revenues, in 2011.

Provision for income taxes. The provision for income taxes was 39% and 40% for the years ended December 31, 2012 and 2011, respectively. The 2012 decrease is primarily due to the resolution of certain tax matters.

Liquidity and Capital Resources

The change in the Company’s liquidity during the years ended December 31, 2013, 2012 and 2011, is primarily the net effect of funds generated by operations and the funds used for capital expenditures, repurchases of common stock and payment of dividends.

Item 7A. Quantitative | and Qualitative Disclosures About Market Risk

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 earnings, investments in its foreign subsidiaries, and the intercompany transactions with its foreign subsidiaries.

For the year ended December 31, 2013, approximately 24% of the Company’s revenues were generated outside of the United States. These operations transact business in their functional currency. As a result, fluctuations in the value of foreign currencies against the U.S. dollar have an impact on the Company’s reported results. 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.

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.

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 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 advertising, marketing, and web design fields. Protiviti provides business consulting and internal audit services, 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, 2013, 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.

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

29

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (Continued)

Note A—Summary of Significant Accounting Policies (Continued)

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 are recognized as services are provided. Revenues on 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.

Costs of Services. Direct costs of temporary and consultant staffing services consist of payroll, payroll taxes and insurance 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 insurance costs, as well as reimbursable expenses.

Advertising Costs. The Company expenses all advertising costs as incurred. Advertising costs for the years ended December 31, 2013, 2012 and 2011, are reflected in the following table (in thousands):

|  | Years Ended December 31, |
|  | 2013 |  |  | 2012 |  |  | 2011 |
Advertising Costs |  | $ | 38,845 |  |  | $ | 42,256 |  |  | $ | 42,728 |

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, 2013, 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, 2013 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

30

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (Continued)

Note A—Summary of Significant Accounting Policies (Continued)

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.

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 $37.0 million and $39.3 million were recorded as of December 31, 2013 and 2012, 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 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.

31

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (Continued)

Note A—Summary of Significant Accounting Policies (Continued)

No stock appreciation rights have been granted under the Company’s existing stock plans.

The Company determines the fair value of options to purchase common stock using the Black-Scholes valuation model. The Company recognizes expense over the service period for options that are expected to vest and records adjustments to compensation expense at the end of the service period if actual forfeitures differ from original estimates. 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, 2013, 2012 and 2011, are reflected in the following table (in thousands):

|  | Years Ended December 31, |
|  | 2013 |  |  | 2012 |  |  | 2011 |
Internal-use software development costs |  | $ | 13,027 |  |  | $ | 19,083 |  |  | $ | 18,133 |

Note B—New Accounting Pronouncements

Balance Sheet Disclosures. In December 2011, the Financial Standards Board (“FASB”) issued authoritative guidance in regards to the presentation of netting assets and liabilities related to financial and derivative instruments as a single amount in the statement of financial position to address the difference between GAAP and international financial reporting standards (“IFRS”). This authoritative guidance is to be applied for annual reporting periods beginning on or after January 1, 2013, and interim periods within those annual periods. The adoption of this guidance as of March 31, 2013, did not have an impact on the Company’s Financial Statements.

Comprehensive Income. In March 2013, the FASB issued authoritative guidance in regards to comprehensive income and reporting amounts reclassified out of accumulated other comprehensive income to improve the transparency of reporting these reclassifications. Other comprehensive income which included gains and losses that are initially excluded from net income for an accounting period would need to be presented either on the face of the statement where net income is presented or in the notes. This authoritative guidance is to be applied for annual reporting periods beginning after December 15, 2012. The adoption of this guidance as of March 31, 2013, did not have an impact on the Company’s Financial Statements.

Income Taxes. In September 2013, the FASB issued authoritative guidance in regards to the presentation of unrecognized tax benefits when a net operating loss carryforward, a similar tax loss, or a tax credit carryforward exists. The amendment states that an unrecognized tax benefit or a portion of the unrecognized tax benefit should be presented in the financial statements as a reduction to a deferred tax asset for a net operating loss carryforward, a similar tax loss, or a tax credit carryforward. This authoritative guidance is to be applied for fiscal years, and interim periods within those years, beginning after December 15, 2013. The Company does not expect that the adoption of this guidance will have a material impact on its Financial Statements.

Deposits in trusts for employee benefits increased for the year ended December 31, 2013 due to changes in the Company’s broad-based Deferred Salary Savings Plan (the “Plan”) whereby previously unfunded employee accrual accounts were funded so that employees could direct the investments in their accounts. The Company’s executive officers do not participate in the Plan.

Note G—Notes Payable and Other Indebtedness

The Company issued promissory notes as well as other forms of indebtedness in connection with certain acquisitions and other payment obligations. These are due in varying installments, carry varying interest rates and, in aggregate, amounted to $1.4 million at December 31, 2013, and $1.5 million at December 31, 2012. At December 31, 2013, $1.4 million of the notes were collateralized by a standby letter of credit.

Note H—Income Taxes (Continued)

enterprise zone tax credits of $6.3 million that expire in 2023. New legislation passed by the State of California in 2013 limits the carryforward period on the enterprise zone credits to 10 years; therefore, the company expects that it will utilize $3.2 million of these credits prior to expiration.

The Company has not provided deferred income taxes or foreign withholding taxes on $2.8 million and $2.2 million of undistributed earnings of its non-U.S. subsidiaries as of December 31, 2013 and 2012, respectively, since the Company intends to reinvest these earnings indefinitely. The U.S. tax impact upon repatriation, net of foreign tax credits, would be zero for the years ended December 31, 2013 and 2012.

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, 2011 to December 31, 2013 (in thousands):

|  | December 31, |
|  | 2013 |  |  | 2012 |  |  | 2011 |

Balance at end of period |  | $ | 6,110 |  |  | $ | 7,097 |  |  | $ | 11,669 |

The total amount of unrecognized tax benefits that, if recognized, would impact the effective tax rate is $1.3 million, $1.0 million and $2.7 million for 2013, 2012 and 2011, 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 as of December 31, 2013, is $2.8 million, including a $0.3 million reduction recorded in income tax expense during the year. The total amount of interest and penalties accrued as of December 31, 2012, was $3.1 million, including a $2.3 million reduction recorded in income tax expense during the year. The total amount of interest and penalties accrued as of December 31, 2011, was $5.3 million, including a $0.3 million increase 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, $2.2 million of the unrecognized gross tax benefit has been classified as a current liability as of December 31, 2013. 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 and Germany. For U.S. federal income tax, the Company remains subject to examination for 2010 and subsequent years. For major U.S. states, with few exceptions, the Company remains subject to examination for 2009 and subsequent years. Generally, for the foreign countries, the Company remains subject to examination for 2006 and subsequent years.

Note I—Commitments and Contingencies

Rental expense, primarily for office premises, amounted to $92.7 million, $96.8 million and $100.6 million for the years ended December 31, 2013, 2012 and 2011, respectively. The approximate minimum rental commitments for 2014 and thereafter under non-cancelable leases in effect at December 31, 2013 were as follows (in thousands):

Additionally, as of December 31, 2013, the Company had future purchase commitments of approximately $55 million over the next three years primarily related to telecom service agreements, software licenses and subscriptions, and computer hardware and software maintenance agreements.

On April 23, 2010, Plaintiffs David Opalinski and James McCabe, on behalf of themselves and a putative class of similarly situated Staffing Managers, filed a Complaint in the United States District Court for the District of New Jersey naming the Company and one of its subsidiaries as Defendants. The Complaint alleges that salaried Staffing Managers located throughout the U.S. have been misclassified as exempt from the Fair Labor Standards Act’s overtime pay requirements. Plaintiffs seek an unspecified amount for unpaid overtime on behalf of themselves and the class they purport to represent. Plaintiffs also seek an unspecified amount for statutory penalties, attorneys’ fees and other damages. On October 6, 2011, the Court granted the Company’s motion to compel arbitration of the Plaintiffs’ allegations. At this stage, it is not feasible to predict the outcome of or a range of loss, should a loss occur, from these allegations 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 allegations.

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, 2013, the Company is authorized to repurchase, from time to time, up to 8.1 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, 2013, 2012 and 2011, are reflected in the following table (in thousands):

Additional stock repurchases were made in connection with employee stock plans, whereby Company shares were tendered by employees for the payment of exercise price and applicable statutory withholding taxes. The number and the cost of employee stock plan repurchases made during the years ended December 31, 2013, 2012 and 2011, are reflected in the following table (in thousands):

|  | Years Ended December 31, |

Employee stock plan repurchased |  | $ | 44,169 |  |  | $ | 50,045 |  |  | $ | 29,017 |

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, 2013, (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, 2013, 2012 and 2011, are reflected in the following table:

|  | Years Ended December 31, |
|  | 2013 |  |  | 2012 |  |  | 2011 |
Cash dividends declared per share |  | $ | .64 |  |  | $ | .60 |  |  | $ | .56 |

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. As a result, the Company had $13.3 million in retained earnings as of December 31, 2013 and no retained earnings as of December 31, 2012 and 2011.

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 over four years. Shares offered under the plan are authorized but unissued shares or treasury shares.

Options currently outstanding under the plans have an exercise price equal to the fair market value of the Company’s common stock at the date of grant and consist of non-statutory stock options under the Internal Revenue Code, and generally have a term of 10 years.

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 for grants made prior to July 28, 2009, receive all dividends with respect to such shares on the dividend payment dates, whether or not the shares have vested as long as any performance condition has been met. 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. Compensation expense for restricted stock and stock units is generally recognized on either a 3 year cliff basis or 4 year straight line basis, based on the stock’s fair market value on the grant date. For restricted stock grants issued with performance conditions, compensation expense is recognized over each vesting tranche.

FASB authoritative guidance requires that excess tax benefits be recognized as an addition to capital surplus and that unrealized tax benefits be recognized as income tax expense unless there are excess tax benefits from

Note K—Stock Plans (Continued)

previous equity awards to which it can be offset. The Company calculates the amount of eligible excess tax benefits that are available to offset future tax shortfalls in accordance with the long-form method described in the FASB authoritative guidance.

The Company determines the fair value of options to purchase common stock using the Black-Scholes valuation model. The Company recognizes expense over the service period for options that are expected to vest and records adjustments to compensation expense at the end of the service period if actual forfeitures differ from original estimates. The Company has not granted any options to purchase common stock since 2006.

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, 2013, the Company granted performance shares to its executives in the form of restricted stock. The shares granted contain (1) a performance condition based on target net income per share, and (2) a market condition based on Total Shareholder Return (“TSR”). The TSR market condition measures the Company’s performance against a peer group. Shares will be delivered at the end of the three year vesting and TSR performance period based on the Company’s actual performance compared to the peer group. Actual shares earned will range from fifty percent (50%) to one hundred fifty percent (150%) of the target award after any adjustment made for the performance condition. The fair value of this award was determined using a Monte Carlo simulation with the following assumptions: an historical volatility of 32.23%, 0% dividend yield and a risk-free interest rate of 0.36%. The historical volatility was based on the most recent 2.61-year period for the Company and the components of the peer group. The stock price projection for the Company and the components of the peer group assumes a 0% dividend yield. This is mathematically equivalent to reinvesting dividends in the issuing entity over the performance period. The risk-free interest rate is equal to the yield, as of the measurement date, of the zero-coupon U.S. Treasury bill that is commensurate with the remaining performance measurement period.

Stock-based compensation expense consisted of the following (in thousands):

|  | Years Ended December 31, |
|  | 2013 |  |  | 2012 |  |  | 2011 |
Restricted stock and stock units |  | $ | 38,867 |  |  | $ | 41,464 |  |  | $ | 50,906 |

The permanent placement 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 or loss 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.:

In our opinion, the consolidated financial statements listed in the index appearing under Item 15(a)(1) present fairly, in all material respects, the financial position of Robert Half International Inc. and its subsidiaries at December 31, 2013 and 2012, and the results of their operations and their cash flows for each of the three years in the period ended December 31, 2013 in conformity with accounting principles generally accepted in the United States of America. In addition, in our opinion, the financial statement schedule listed in the index appearing under Item 15(a)(2) presents fairly, in all material respects, the information set forth therein when read in conjunction with the related consolidated financial statements. Also in our opinion, the Company maintained, in all material respects, effective internal control over financial reporting as of December 31, 2013, based on criteria established in Internal Control—Integrated Framework (1992) issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO). The Company’s management is responsible for these financial statements and financial statement schedule, 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 in Item 9A. Our responsibility is to express opinions on these financial statements, on the financial statement schedule, and on the Company’s internal control over financial reporting based on our integrated audits. We conducted our audits in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audits to obtain reasonable assurance about whether the financial statements are free of material misstatement and whether effective internal control over financial reporting was maintained in all material respects. Our audits of the financial statements included examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements, assessing the accounting principles used and significant estimates made by management, and evaluating the overall financial statement presentation. 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.

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.

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, 2013, using criteria established in Internal Control-Integrated Framework (1992) 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, 2013.

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, 2013, has been audited by PricewaterhouseCoopers LLP, an independent registered public accounting firm, as stated in their report which is included herein.
