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 began operations in May 2002 and provides business and technology risk consulting and internal audit services. Protiviti, which primarily employs risk consulting and internal audit professionals formerly associated with major accounting firms, 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 Andersen. These professionals formed the base of the Company’s new Protiviti Inc. subsidiary. Protiviti^® has enabled the Company to enter the market for independent internal audit and business and technology risk consulting 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 increasingly 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 only when working on customer assignments. 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.

1

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 and Robert Half Finance & Accounting divisions.

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 programming, networking, systems integration, database design and help desk 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 provides independent internal audit and business and technology risk consulting services. Protiviti helps clients identify, measure, and manage operational and technology-related risks they face within their industries and throughout their systems and processes. Protiviti offers a full spectrum of professional consulting services, technologies, and skills for business and technology risk management and the continual transformation of internal audit functions.

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

2

clients and employment candidates consists primarily of yellow pages advertisements, classified advertisements, websites, trade shows, outdoor mass-transit media, branded speaking events and advertising on the Internet. 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, print advertisements in national newspapers, magazines and certain trade journals. The Company has initiated programs to take advantage of the Internet as a resource for recruiting candidates and filling client orders. Recent Internet initiatives include forging traffic building alliances with leading Internet career search sites. The Company plans to expand its use of the Internet 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. The Company also conducts public relations activities designed to enhance public recognition of the Company and its services. Local employees are encouraged to be active in civic organizations and industry trade groups.

Protiviti markets its risk 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 initiated a national direct mail program to share information with clients on current corporate governance and risk management issues. It conducts public relations activities, such as press releases 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 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 Pleasanton, 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 March 1, 2006, the Company conducted its staffing services operations through more than 330 offices in 42 states, the District of Columbia and thirteen 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 committee consisting of key operating personnel, with operational and administrative support provided by individuals located in Pleasanton and Menlo Park, California. As of March 1, 2006, Protiviti had more than 50 offices in 22 states and eleven 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.

3

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 due to many new firms entering the market and the evolution of established firms in the business space. In addition, the changing regulatory environment is increasing opportunities for non-attestation audit and risk consulting services. The principal competitors of Protiviti remain the “big four” accounting firms. Significant competitive factors include reputation, technology, tools, project methodologies, price of services and depth of skills of personnel. Protiviti believes its competitive strengths lie in its unique ability to couple the deep skills and proven methodologies of its “big four” heritage with the customer focus and attention of a smaller organization.

Employees

The Company has approximately 11,000 full-time staff employees, including approximately 2,200 engaged directly in Protiviti operations. The Company placed approximately 219,000 employees on temporary assignments with clients during 2005. Temporary employees placed by the Company 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 has been in operation only since May 2002, so there does not exist sufficient information to determine to what extent, if any, its business may be seasonal. 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.

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:

Business Highly Dependent Upon the State of the Economy.    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.

Availability of Candidates.    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.

Highly Competitive Business.    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.

Reputation.    The success of the Company’s staffing and Protiviti businesses is highly dependent upon their reputations. Any event that adversely impacts the reputation of either business could materially adversely affect the Company.

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 or harassment. 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. 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.

Dependence Upon Personnel.    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.

Government Regulation.    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

5

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.

Government Regulation of the Workplace.    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.

Demand for Services.    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.

Reliance on Short-Term Contracts.    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.

The Company and certain subsidiaries are defendants in several class action lawsuits alleging various wage and hour claims that could cause the Company to incur substantial liabilities.    The Company and certain subsidiaries are defendants in several class 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 matters. The Company and certain subsidiaries are currently defendants in two class action lawsuits in California and one class action lawsuit in Massachusetts. All three lawsuits allege, among other things, the misclassification of certain employees as exempt employees under federal and state law and other related wage and hour violations and seek an unspecified amount for unpaid overtime compensation, statutory 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 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.

Protiviti Dependence on 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 Competition.    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.

Potential Liability.    The business of Protiviti consists of providing internal audit and business and technology risk consulting 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 1B.    Unresolved Staff Comments.

Not applicable.

Item 2.    Properties

The Company’s headquarters operations are located in Menlo Park and Pleasanton, California. As of March 1, 2006, placement activities were conducted through more than 330 offices located in the United States, Canada, the United Kingdom, Belgium, France, the Netherlands, Germany, the Czech Republic, Ireland, Italy, Luxembourg, Japan, Australia and New Zealand. As of March 1, 2006, Protiviti had more than 50 offices in the United States, Canada, Mexico, Australia, China, France, Germany, Italy, Netherlands, Japan, Singapore and the United Kingdom. All of the offices are leased.

Item 3.    Legal Proceedings

On August 9, 2005, Plaintiff Lizette Greene, on behalf of herself and a putative class of salaried “inside sales persons,” filed a complaint in United States District Court for the Northern District of California naming the Company and three of its wholly owned subsidiaries as Defendants. On December 1, 2005, the Plaintiff amended the Complaint. The Amended Complaint alleges that purported “inside sales persons” based in California have been misclassified under federal law as exempt employees and seeks an unspecified amount for unpaid overtime pay alleged to be due to them had they been paid as non-exempt, hourly employees. In addition, the Plaintiff also makes two claims under the California Private Attorney Generals Act seeking an unspecified amount for statutory penalties for alleged violations of the California Labor Code arising from the alleged misclassification of these employees as exempt employees. Plaintiff also makes a claim under California Business and Professions Code § 17200 claim for a putative nation wide class of purported “inside sales persons.” This litigation is at a very early stage and discovery has not commenced. At this early stage of the litigation, it is not feasible to predict the outcome of or a range of loss, should a loss occur, from this proceeding, and accordingly, no amounts have been provided in the accompanying financial statements. The Company believes it has meritorious defenses to the allegations, and the Company intends to continue to vigorously defend against the litigation.

On December 6, 2004, Plaintiffs Ian O’Donnell and David Jolicoeur, on behalf of themselves and a putative class of salaried Staffing Managers, Account Executives and Account Managers, filed a complaint in Massachusetts Superior Court naming the Company and one of its wholly owned subsidiaries as Defendants. The complaint alleges that salaried Staffing Managers, Account Executives and Account Managers based in Massachusetts within the past two years have been misclassified under Massachusetts law as exempt employees and seeks an unspecified amount equal to three times their unpaid overtime compensation alleged to be due to them had they been paid as non-exempt, hourly employees, plus costs and legal fees. The complaint also makes similar allegations under the U.S. Fair Labor Standards Act on behalf of all Staffing Managers, Account Executives and Account Managers employed in any state other than Massachusetts and California within the past three years and seeks an unspecified amount for unpaid overtime pay alleged to be due to them had they been paid as non-exempt, hourly employees, plus an equal amount as liquidated damages. The case has been removed to the United States District Court for the District of Massachusetts. Plaintiffs have filed a motion with the Court seeking conditional certification of the class and permission to mail class members a notice regarding their right to opt into the case as a plaintiff. The Company has opposed such motion and has commenced discovery. On November 30, 2005, plaintiffs filed a motion with the Court seeking permission to amend the complaint to allege that the Company failed to pay its exempt employees on a “salary basis.” If the motion to amend is allowed, the putative class would expand beyond Staffing Managers, Account Executives and Account Managers as initially proposed, and would include all Company employees classified as exempt during the time period covered by the lawsuit. The Company has opposed the motion to amend the complaint. Because the litigation is at an early stage, it is not feasible to predict its outcome or a range of loss, should a loss occur. Accordingly, no amounts have been provided in the accompanying financial statements. The Company believes it has meritorious defenses to the allegations, and the Company intends to continue to vigorously defend against the litigation.

On September 10, 2004, Plaintiff Mark Laffitte, on behalf of a putative class of salaried Account Executives and Staffing Managers, filed a complaint in California Superior Court naming the Company and three of its wholly owned subsidiaries as Defendants. The complaint alleges that salaried Account Executives and Staffing Managers based in California have been misclassified under California law as exempt employees and seeks an

7

unspecified amount for unpaid overtime pay alleged to be due to them had they been paid as non-exempt hourly employees. In addition, the plaintiff seeks an unspecified amount for statutory penalties for alleged violations of the California Labor Code arising from the alleged misclassification of these employees as exempt employees. This litigation is at an early stage and discovery has commenced. At this early stage of the litigation, it is not feasible to predict the outcome of or a range of loss, should a loss occur, from this proceeding, and accordingly, no amounts have been provided in the accompanying financial statements. The Company believes it has meritorious defenses to the allegations, and the Company intends to vigorously defend against litigation.

The Company is involved in a number of other lawsuits arising in the ordinary course of business. While management does not expect any of these matters to have a material adverse effect on the Company’s results of operations, financial position or cash flows, litigation is subject to certain inherent uncertainties.

Item 6.    Selected Financial Data

The selected five-year financial data presented below should be read in conjunction with the information contained in Item 7. Management’s Discussion and Analysis of Financial Condition and Results of Operations, and the Company’s Consolidated Financial Statements and the Notes thereto contained in Item 8. Financial Statements and Supplementary Data.

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

Certain information contained in Management’s Discussion and Analysis and in other parts of this report may be deemed forward-looking statements regarding events and financial trends that may affect the Company’s future operating results or financial positions. These statements may be identified by words such as “estimate”, “forecast”, “project”, “plan”, “intend”, “believe”, “expect”, “anticipate”, or variations or negatives thereof or by similar or comparable words or phrases. Forward-looking statements are subject to risks and uncertainties that could cause actual results to differ materially from those expressed in the statements. These risks and uncertainties include, but are not limited to, the following: changes 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; whether governments will impose additional regulations or licensing requirements on personnel services businesses in particular or on employer/employee relationships in general; whether there will be ongoing demand for Sarbanes-Oxley or other regulatory compliance services; and 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. 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. Further information regarding these and other risks and uncertainties is contained in Item 1A. “Risk Factors.” 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.

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 accounts receivable allowances for estimated losses resulting from the inability of its customers to make required payments. If the financial condition of the Company’s customers were to deteriorate, resulting in an impairment of their ability to make payments, additional allowances may be required. Estimates used in determining the accounts receivable allowances were based on current trends and historical loss statistics. Actual results may differ from these estimates, which may materially affect the Company’s future financial results.

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. The Company records deferred tax assets and liabilities and evaluates the need for valuation allowances to reduce the deferred tax assets to realizable amounts. The likelihood of a material change in the Company’s expected realization of these assets is dependent on future taxable income, its ability to use foreign tax credit carryforwards and carrybacks, final U.S. and foreign tax settlements, and the effectiveness of its tax planning strategies in the various relevant jurisdictions. While management believes that its judgments and interpretations regarding deferred income tax assets and liabilities are appropriate, significant differences in actual experience may materially affect the future financial results of the Company.

11

Employee Retirement Plans.    The determination of the Company’s obligations for its defined benefit retirement agreement for the Company’s Chief Executive Officer is dependent upon various assumptions, including, among others, expected retirement age, mortality, expected post retirement Consumer Price Index increases, and discount rates. Management believes its assumptions are appropriate; however, significant differences in actual experience or significant changes in assumptions may materially affect the Company’s future financial results.

Goodwill Impairment.    The Company assesses the impairment of goodwill and identifiable intangible assets annually, or more often if events or changes in circumstances indicate that the carrying value may not be recoverable. This assessment is based upon a discounted cash flow analysis. The estimate of cash flow is based upon, among other things, certain assumptions about expected future operating performance and an appropriate discount rate determined by management. The Company’s estimates of discounted cash flow may differ from actual cash flow due to, among other things, economic conditions, changes to its business model or changes in its operating performance. Significant differences between these estimates and actual cash flow could materially affect the future financial results of the Company. The Company completed its annual goodwill impairment analysis during each of the years ended December 31, 2005 and 2004, and determined that no adjustment to the carrying value of goodwill was required.

Workers’ Compensation.    The Company self-insures or retains a portion of the exposure for losses related to workers’ compensation. The Company has established reserves for workers’ compensation claims based on historical loss statistics and periodic third party actuarial valuations. 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 financial results.

Stock Option Plans.    The Company has a long history of issuing stock options to employees and directors as an integral part of its compensation programs. Accounting principles generally accepted in the United States of America allow alternative methods of accounting for these plans. The Company has chosen to account for its stock option plans under Accounting Principles Board (“APB”) Opinion No. 25, Accounting for Stock Issued to Employees (“APB 25”). Under APB 25, the intrinsic value of the options is used to record compensation expense and, as a result, no compensation expense related to stock options is included in determining net income and net income per share in the Financial Statements. Restricted stock and stock unit grants are accounted for in accordance with APB 25. APB 25 mandates that restricted stock grants with performance conditions are calculated using the intrinsic value. As required by Statement of Financial Accounting Standards (“SFAS”) No. 148, Accounting for Stock-Based Compensation—Transition and Disclosure, calculations of pro forma net income (loss) and net income (loss) per share, computed in accordance with the method prescribed by SFAS No. 123, Share-Based Payment (“SFAS 123”), are set forth in Note A to the Financial Statements.

Recent Accounting Pronouncements

In June 2005, the Emerging Issues Task Force (“EITF”) issued Issue No. 05-6, Determining the Amortization Period for Leasehold Improvements (“EITF 05-6”), which requires that leasehold improvements that are placed in service significantly after and not contemplated at or near the beginning of a lease term be amortized over the shorter of the useful life of the assets or a term that includes required lease periods and renewal periods that are deemed to be reasonably assured at the date the leasehold improvements are purchased. The adoption of EITF 05-6 during the three months ended September 30, 2005 did not have an impact on the Company’s Financial Statements.

In March 2005, the Financial Accounting Standards Board (“FASB”) issued FASB Interpretation No. 47, Accounting for Conditional Asset Retirement Obligations, An Interpretation of FASB Statement No. 143, (“FIN 47”) which requires an entity to recognize a liability for the fair value of a conditional asset retirement obligation when incurred if the liability’s fair value can be reasonably estimated. The Company adopted the provisions of FIN 47 in the three months ended December 31, 2005. The adoption of FIN 47 did not have a material impact on its consolidated financial position, results of operations or cash flows.

12

In May 2005, the FASB issued SFAS No. 154, Accounting Changes and Error Corrections—A replacement of APB Opinion No. 20 and FASB Statement No. 3 (“SFAS 154”). SFAS 154 applies to all voluntary changes in accounting principle, and changes the requirements for accounting for and reporting of a change in accounting principle. SFAS 154 requires retrospective application to prior periods’ financial statements of a voluntary change in accounting principle unless it is impracticable. APB Opinion No. 20 previously required that most voluntary changes in accounting principle be recognized by including in net income of the period of the change the cumulative effect of changing to the new accounting principle. The provisions in SFAS 154 are effective for accounting changes and correction of errors made in fiscal years beginning after December 15, 2005. Accordingly, the Company will adopt SFAS 154 effective January 1, 2006. The adoption of SFAS 154 is not expected to have a material effect on the Company’s results of operations.

During December 2004, the FASB issued SFAS No. 123 (revised 2004), Share-Based Payment (“SFAS 123R”), which revises SFAS 123 and supersedes APB 25. SFAS 123R requires all share-based payments to employees, including grants of employee stock options, to be recognized as expense based on their fair values. In April 2005, the SEC amended the effective date of SFAS 123R to be the first annual period beginning after June 15, 2005. The pro forma disclosures previously permitted under SFAS 123 will no longer be an alternative to expense recognition. Under SFAS 123R, the Company will be required to select a valuation technique, or option pricing model that meets the criteria as stated in the standard. Allowable valuation models include a binomial model and the Black-Scholes model. The Company is required to adopt the provisions of SFAS 123R in the first quarter of 2006. The Company is in the process of assessing the impact on the Company’s results of operations from the adoption of SFAS 123R for its effect on prospective option grants. The adoption of SFAS 123R requires the Company to value stock options granted prior to its adoption of SFAS 123R under the fair value method and expense these amounts in the income statement over the stock option’s remaining vesting period. This will result in the Company expensing approximately $17 million, before income tax effects, in 2006 that would previously have been presented in a pro forma footnote disclosure. In addition, SFAS 123R will require the Company to reflect the tax savings resulting from tax deductions in excess of expense reflected in its financial statements as a financing cash flow, which will impact the Company’s future reported cash flow from operating activities.

In March 2005, the SEC staff issued Staff Accounting Bulletin No. 107 (“SAB 107”) to give guidance on the implementation of SFAS 123R. The Company will consider SAB 107 during implementation of SFAS 123R.

Results of Operations for the Three Years Ended December 31, 2005

Temporary and consultant staffing services revenues were $2.6 billion, $2.2 billion and $1.7 billion for the years ended December 31, 2005, 2004 and 2003, respectively, increasing by 21% and 25% in 2005 and 2004, respectively. Permanent placement revenues were $219 million, $136 million and $95 million for the years ended December 31, 2005, 2004 and 2003, respectively, increasing by 61% and 43% in 2005 and 2004, respectively. Improvement in the U.S. labor markets contributed to the increase in temporary and permanent staffing services revenues for the years ended December 31, 2005 and 2004. Risk consulting and internal audit services revenues were $479 million, $352 million and $133 million for the years ended December 31, 2005, 2004 and 2003, respectively, increasing by 36% and 164% in 2005 and 2004, respectively. The 2005 and 2004 increases in risk consulting and internal audit services revenues is primarily due to increased brand acceptance in the marketplace and expanding demand related to increased focus on internal accounting controls and other corporate governance requirements, including the Sarbanes-Oxley Act of 2002. There can be no assurances that there will be ongoing demand for Sarbanes-Oxley or other regulatory compliance services, or that future results can be reliably predicted by considering past trends or extrapolating past results. We expect total Company revenues to continue to be impacted by general macroeconomic conditions in 2006.

The Company’s temporary and permanent staffing services business has more than 330 offices in 42 states, the District of Columbia and twelve foreign countries, while Protiviti has more than 45 offices in 22 states and ten foreign countries. Revenues from foreign operations represented 19%, 18% and 18% of revenues for the years ended December 31, 2005, 2004 and 2003, respectively.

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. Gross margin dollars from permanent placement staffing services are equal to revenues, as there are no direct costs associated with such revenues. 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 temporary and consultant staffing services were $963 million, $787 million and $610 million for the years ended December 31, 2005, 2004 and 2003, respectively, increasing by 22% and 29% in 2005 and 2004, respectively. Gross margin amounts equaled 36%, 36% and 35% of revenues for temporary and consultant staffing services for the years ended December 31, 2005, 2004 and 2003, respectively. The higher 2004 temporary and consultant gross margin percentage is primarily the result of higher bill rates and conversion revenues. Gross margin dollars for the Company’s permanent placement staffing division were $219 million, $136 million and $95 million for the years ended December 31, 2005, 2004 and 2003, respectively, increasing by 61% and 43% in 2005 and 2004, respectively. Gross margin dollars for the Company’s risk consulting and internal audit division were $190 million, $133 million and $22 million for the years ended December 31, 2005, 2004 and 2003, respectively. Gross margin amounts equaled 40%, 38% and 16% of revenues for risk consulting and internal audit services for the years ended December 31, 2005, 2004 and 2003, respectively. The 2005 and 2004 improvements in risk consulting and internal audit services gross margin dollars is primarily the result of higher revenues and improved staff utilization.

Selling, general and administrative expenses were $991 million in 2005, compared to $824 million in 2004 and $707 million in 2003. Selling, general and administrative expenses as a percentage of revenues were 30%, 31% and 36% for the years ended December 31, 2005, 2004 and 2003, respectively. Selling, general and administrative expenses consist primarily of staff compensation, advertising, depreciation and occupancy costs. The lower 2005 and 2004 selling, general and administrative expense percentages resulted primarily from leveraging fixed operating costs.

For acquisitions, the Company allocates the excess of cost over the fair market value of the net tangible assets first to identifiable intangible assets, if any, and then to goodwill. 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 test during each of the years ended December 31, 2005 and 2004, and determined that no adjustment to the carrying value of goodwill was required. Net intangible assets, consisting primarily of goodwill, represented 13% of total assets and 17% of total stockholders’ equity at December 31, 2005.

Interest income for the years ended December 31, 2005, 2004 and 2003 was $12.1 million, $5.0 million and $3.4 million, respectively, while interest expense for the years ended December 31, 2005, 2004 and 2003 was $1.1 million, $1.2 million and $0.8 million, respectively. Higher average cash balances in 2005 and 2004 and higher interest rates during those years yielded higher interest income.

The provision for income taxes was 39%, 40% and 45% of income before taxes for the years ended December 31, 2005, 2004 and 2003, respectively. The decreases in 2005 and 2004 are due primarily to the diminishing impact of permanent non-deductible tax items, which became increasingly less significant relative to the Company’s improved financial results, and to the utilization of net operating loss carryforwards in certain states and international locations.

Liquidity and Capital Resources

The change in the Company’s liquidity during the years ended December 31, 2005, 2004 and 2003 is primarily the net effect of funds generated by operations and the funds used for capital expenditures, repurchases of common stock, payment of dividends and principal payments on outstanding notes payable.

14

In connection with the preparation of its report on Form 10-Q for the quarterly period ended March 31, 2005, the Company concluded that it was appropriate to classify its auction rate securities as marketable securities. Previously, such investments had been classified as cash and cash equivalents. Accordingly, adjustments have been made to the Company’s Consolidated Statements of Cash Flows for the years ended December 31, 2004 and 2003 to reflect the gross purchases and sales of these securities as investing activities rather than as a component of cash and cash equivalents.

Cash, cash equivalents and marketable securities were $458 million, $437 million and $377 million at December 31, 2005, 2004 and 2003, respectively. Operating activities and investing activities provided $328 million and $22 million, respectively, during the year ended December 31, 2005, partially offset by $232 million of net cash used in financing activities. Operating activities provided $162 million during the year ended December 31, 2004, partially offset by $37 million and $76 million of net cash used in investing activities and financing activities, respectively. Operating activities provided $113 million during the year ended December 31, 2003, partially offset by $57 million and $8 million of net cash used in investing activities and financing activities, respectively.

Operating activities—Net cash provided by operating activities for the year ended December 31, 2005 was composed of net income of $238 million adjusted for non-cash items of $122 million, and net cash used for changes in working capital of $32 million. Net cash provided by operating activities for the year ended December 31, 2004 was composed of net income of $141 million adjusted for non-cash items of $93 million, and net cash used for changes in working capital of $72 million. Net cash provided by operating activities for the year ended December 31, 2003 was composed of net income of $6 million adjusted for non-cash items of $98 million, and net cash provided by changes in working capital of $9 million.

Investing activities—Cash provided by investing activities for the year ended December 31, 2005 was $22 million. This was primarily composed of proceeds from sales and maturities of marketable securities of $92 million, partially offset by capital expenditures of $62 million, purchases of goodwill and other intangible assets of $4 million, and deposits to trusts for employee benefits and retirement plans of $3 million. Cash used in investing activities for the year ended December 31, 2004 was $37 million. This was primarily capital expenditures of $33 million. Cash used in investing activities for the year ended December 31, 2003 was $57 million. This was primarily capital expenditures of $37 million and purchases of goodwill and other intangible assets of $18 million.

Financing activities—Cash used in financing activities for the year ended December 31, 2005 was $232 million. This included repurchases of $262 million in common stock and $48 million in cash dividends to stockholders, partially offset by proceeds of $77 million from exercises of stock options. Cash used in financing activities for the year ended December 31, 2004 was $76 million. This included common stock repurchases of $90 million and cash dividends to stockholders of $31 million, partially offset by proceeds of $44 million from exercises of stock options. Financing activities for the year ended December 31, 2003 was $8 million. This included common stock repurchases of $33 million, partially offset by proceeds of $25 million from exercises of stock options.

As of December 31, 2005, the Company is authorized to repurchase, from time to time, up to 9.3 million additional shares of the Company’s common stock on the open market or in privately negotiated transactions, depending on market conditions. During the years ended December 31, 2005, 2004 and 2003, the Company repurchased approximately 7.6 million, 2.7 million and 1.6 million shares of common stock on the open market for a total cost of $222 million, $64 million and $25 million, respectively. Additional stock repurchases were made in connection with employee stock plans, whereby Company shares were tendered by employees for the payment of applicable statutory withholding taxes. During the years ended December 31, 2005, 2004 and 2003, such repurchases totaled approximately 1.6 million, 1.0 million and 0.5 million shares at a cost of $53 million, $25 million and $8 million, respectively. Repurchases of securities have been funded with cash generated from operations.

15

The Company’s working capital at December 31, 2005 included $458 million in cash and cash equivalents. The Company’s working capital requirements relate primarily to accounts receivable. While there can be no assurances in this regard, the Company expects that internally generated cash will be sufficient to support the working capital needs of the Company, the Company’s fixed payments, dividends, and other obligations on both a short- and long-term basis.

On February 15, 2006, the Company announced a quarterly dividend of $.08 per share to be paid to all shareholders of record on February 27, 2006. The dividend will be paid on March 15, 2006.

The Company’s cash flows generated from operations are also the primary source for funding various contractual obligations. The table below summarizes the Company’s major commitments as of December 31, 2005 (in thousands):

Long-term debt obligations consist of promissory notes and related interest as well as other forms of indebtedness issued in connection with certain acquisitions and other payment obligations. Operating lease obligations consist of minimum rental commitments for 2006 and thereafter under non-cancelable leases in effect at December 31, 2005. Purchase obligations consist of purchase commitments primarily related to telecom service agreements, software licenses and subscriptions, and computer hardware and software maintenance agreements.

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, 2005, approximately 19% 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 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 provides business and technology risk consulting and internal audit services. Protiviti, which primarily employs risk consulting and internal audit professionals formerly associated with major accounting firms, is a wholly-owned subsidiary of the Company. Revenues are predominantly derived from specialized staffing services. The Company operates in the United States, Canada, Mexico, Europe, Asia, Australia and New Zealand. 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”).

Certain reclassifications have been made to the 2004 and 2003 financial statements to conform to the 2005 presentation. In connection with the preparation of its report on Form 10-Q for the quarterly period ended March 31, 2005, the Company concluded that it was appropriate to classify its auction rate securities as marketable securities. Previously, such investments had been classified as cash and cash equivalents. Accordingly, the Company has revised the classification to report these securities as marketable securities in a separate line item on its Consolidated Statements of Financial Position as of December 31, 2004. As of December 31, 2005 the Company had no marketable securities. Corresponding adjustments have also been made to the Company’s Consolidated Statements of Cash Flows for the periods ended December 31, 2005, 2004 and 2003, to reflect the gross purchases and sales of these securities as investing activities rather than as a component of cash and cash equivalents. This change in classification does not affect previously reported cash flows from operations or from financing activities in the Company’s previously reported Consolidated Statements of Cash Flows, or the Company’s previously reported Consolidated Statements of Operations for any period.

As of December 31, 2004, $92 million of these current investments were originally classified as cash and cash equivalents on the Company’s Consolidated Statements of Financial Position.

For the years ended December 31, 2004 and 2003, net cash used in investing activities related to these current investments of $2 million and $1 million, respectively, were included in cash and cash equivalents in the Company’s Consolidated Statements of Cash Flows.

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, 2005, such estimates included allowances for uncollectible accounts receivable, workers’ compensation losses, income and other taxes, and certain employee retirement plans.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (Continued)

Note A—Summary of Significant Accounting Policies (Continued)

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. 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. Temporary employees placed by the Company are the Company’s legal employees while they are working on assignments. The Company pays all related costs of employment, including workers’ compensation insurance, state and federal unemployment taxes, social security and certain fringe benefits. The Company assumes the risk of acceptability of its employees to its customers.

Permanent placement staffing revenues—Permanent placement staffing revenues are recognized when employment candidates accept offers of permanent employment. The Company has a substantial history of estimating the effect of permanent placement candidates who do not remain with its clients through the 90-day guarantee period. Allowances are established to estimate these losses. Fees to clients are generally calculated as a percentage of the new employee’s annual compensation. No fees for permanent placement services are charged to employment candidates.

Risk consulting and internal audit revenues—Risk consulting and internal audit services are generally provided on a time-and-material basis or fixed-fee basis. Revenues earned under time-and-material arrangements 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. Reimbursements, including those relating to travel and out-of-pocket expenses, are included in risk consulting and internal audit service revenues, and equivalent amounts of reimbursable expenses are included in direct costs of services.

Costs of Services.    Direct costs of staffing services consist of payroll, payroll taxes and insurance costs for the Company’s temporary employees. There are no direct costs associated with permanent placement staffing services. 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.

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.

Marketable Securities.    During the three months ended June 30, 2005, the Company sold all of its marketable securities. At December 31, 2004, the Company held $92 million of marketable securities, which consisted of auction rate securities classified as available-for-sale. The Company’s investments in these securities are recorded at cost, which approximates fair market value due to their variable interest rates, which typically reset every 35 days, and, despite the long-term nature of their stated contractual maturities, the Company had the ability to quickly liquidate these securities. As a result, the Company has no cumulative gross unrealized holding gains (losses) or gross realized gains (losses) from these marketable securities. All income generated from these current investments is recorded as interest income.

22

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (Continued)

Note A—Summary of Significant Accounting Policies (Continued)

Intangible Assets.    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 during each of the years ended December 31, 2005 and 2004, and determined that no adjustment to the carrying value of goodwill was 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. The Company records deferred tax assets and liabilities and evaluates the need for valuation allowances to reduce the deferred tax assets to realizable amounts. The likelihood of a material change in the Company’s expected realization of these assets is dependent on future taxable income, its ability to use foreign tax credit carryforwards and carrybacks, final U.S. and foreign tax settlements, and the effectiveness of its tax planning strategies in the various relevant jurisdictions.

Workers’ Compensation.    The Company self-insures or retains a portion of the exposure for losses related to workers’ compensation. The Company has established reserves for workers’ compensation claims based on historical loss statistics and periodic third party actuarial valuations.

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 Option Plans.    The Company accounts for its stock option plans in accordance with Accounting Principles Board (“APB”) Opinion No. 25, Accounting for Stock Issued to Employees (“APB 25”). Under APB 25, the intrinsic value of the options is used to record compensation expense and, as a result, no compensation expense related to stock options is included in determining net income and net income per share in the Financial Statements. Restricted stock and stock unit grants are accounted for in accordance with APB 25, which mandates that restricted stock grants with performance conditions are calculated using the intrinsic value. Had compensation expense for the stock options and performance-based restricted stock granted been based on the estimated fair value at the award dates, as prescribed by Statement of Financial Accounting Standards (“SFAS”) No. 123, Accounting for Stock-Based Compensation (“SFAS 123”), the Company’s pro forma net income (loss) and net income (loss) per share would have been as follows (in thousands, except per share amounts):
