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 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 North America, South America, Europe, Asia and Australia. The Company is a Delaware corporation.

Basis of Presentation. The unaudited Condensed 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”). The comparative year-end condensed consolidated statement of financial position data presented was derived from audited financial statements. In the opinion of management, all adjustments (consisting of only normal recurring adjustments) necessary for a fair statement of the financial position and results of operations for the periods presented have been included. These Financial Statements should be read in conjunction with the audited Consolidated Financial Statements of the Company for the year ended December 31, 2006, included in the annual report on Form 10-K. The results of operations for any interim period are not necessarily indicative of, nor comparable to, the results of operations for a full year.

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 March 31, 2007, such estimates included allowances for uncollectible accounts receivable, workers’ compensation losses and income and other taxes.

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 unaudited Condensed 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.

March 31, 2007

Note A—Summary of Significant Accounting Policies (Continued)

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 established to estimate these losses are recorded as a reduction of revenues. 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.

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.

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. 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’s annual goodwill impairment analysis, which will be performed during the second quarter, is not expected to have a material effect on the Financial Statements. No events have occurred since the most recent goodwill impairment analysis which would require interim testing.

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

7

ROBERT HALF INTERNATIONAL INC. AND SUBSIDIARIES

NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS (UNAUDITED)—(Continued)

March 31, 2007

Note A—Summary of Significant Accounting Policies (Continued)

its operations. Deferred tax assets and liabilities are measured and recorded using current enacted tax rates, which the Company expects will apply to taxable income in the years in which those temporary differences are recovered or settled. The likelihood of a material change in the Company’s expected realization of these assets is dependent on future taxable income, its ability to use foreign tax credit carryforwards and carrybacks, final U.S. and foreign tax settlements, and the effectiveness of its tax planning strategies in the various relevant jurisdictions.

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 accrual 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 unaudited Condensed 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. Effective January 1, 2006, the Company adopted the fair value recognition provisions of Statement of Financial Accounting Standards (“SFAS”) No. 123(R), Share-Based Payment (“SFAS 123(R)”).

Property and Equipment. Property and equipment are recorded at cost. Depreciation expense is computed using the straight-line method over the following useful lives:

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. The Company capitalized approximately $3.8 million and $1.0 million of internal-use software development costs for the three months ended March 31, 2007 and 2006, respectively.

Note B—New Accounting Pronouncements

In February 2007, the Financial Accounting Standards Board (“FASB”) issued SFAS No. 159, The Fair Value Option for Financial Assets and Financial Liabilities (“SFAS 159”), which gives entities the option to measure eligible financial assets, and financial liabilities at fair value on an instrument by instrument basis, that are otherwise not permitted to be accounted for at fair value under other accounting standards. The election to use the fair value option is available when an entity first recognizes a financial asset or financial liability. Subsequent changes in fair value must be recorded in earnings. This statement is effective as of the beginning of a company’s first fiscal year after November 15, 2007. The Company is in the process of analyzing the impact of SFAS 159.

Note G—Commitments and Contingencies

On September 10, 2004, Plaintiff Mark Laffitte, on behalf of himself and 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 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. On June 22, 2006, the Court heard cross-motions concerning class certification. On September 18, 2006, the Court issued an order certifying a class with respect to claims for alleged unpaid overtime pay but denied certification with respect to claims relating to meal periods and rest time breaks. At this stage of the litigation, it is not feasible to predict the outcome of or a range of loss, should a loss occur, from this proceeding, and accordingly, no amounts have been provided in the 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. On March 30, 2006, the Court denied Plaintiffs’ first motion seeking conditional certification of their federal claims as a collective action on behalf of a group of Staffing Managers, Account Executives and Account Managers. The same day, the Court allowed Plaintiffs to amend their complaint to add claims that the Company failed to pay its exempt employees on a

“salary basis” as required by Massachusetts and federal law. Plaintiffs have also filed a second motion for

Note G—Commitments and Contingencies (Continued)

conditional certification of their federal claims in which they seek to represent a class of salaried employees who worked for the Company in any state other than California within three years before the original complaint was filed and seeking permission to mail class members a notice regarding their right to opt into the case as Plaintiffs. The Company has opposed that motion, and the Court has not yet issued a ruling. 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 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 for a putative nation wide class of purported “inside sales persons.” On December 22, 2006, the Plaintiff filed a motion for conditional certification of their federal claims in which they seek to represent a class of salaried employees who worked for the Company and certain of its subsidiaries in California within three years before the complaint was filed and seeking permission to mail class members a notice regarding their right to opt into the case as plaintiffs. At this stage of the litigation, it is not feasible to predict the outcome of or a range of loss, should a loss occur, from this proceeding, and accordingly, no amounts have been provided in the 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 March 28, 2006, Plaintiffs Maria Pellegrino, Nadia Balici, Carolyn Cox, Kelli Maresch, Jennifer McCasland and James Rossetto, all former, salaried Account Executives based in California, filed a complaint in California Superior Court naming the Company and three of its wholly owned subsidiaries as Defendants. The complaint alleges that Plaintiffs were misclassified under California 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. Plaintiffs also seek an unspecified amount for statutory penalties for alleged violations of the California Labor Code arising from the alleged misclassification of the Plaintiff employees as exempt employees. On March 13, 2007, the Plaintiffs filed an amended complaint dropping their cause of action for “unfair competition” under the California Business & Professions Code which sought restitutionary damages of unpaid wages for themselves and “all similarly situated employees” as well as recovery of Plaintiffs’ attorneys fees, and added causes of action to recover allegedly unpaid bonuses on behalf of three of the Plaintiffs. The trial date has been continued to September 10, 2007. On April 20, 2007, one of the Plaintiffs filed a motion for summary judgment. A hearing date for the motion has been scheduled for July 6, 2007. At this stage of the litigation, it is not feasible to predict the outcome of or a range of loss, should a loss occur, from this proceeding, and accordingly, no amounts have been provided in the 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 May 4, 2006, Plaintiff Don Tran, on behalf of himself and a putative class of salaried Consultants, and a sub-class of terminated salaried Consultants, filed a complaint in California Superior Court naming Protiviti Inc., a wholly-owned subsidiary of the Company (“Protiviti”), as Defendant. The complaint alleges that salaried

Note G—Commitments and Contingencies (Continued)

consultants based in California have been misclassified under California 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. Plaintiff also 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. The complaint further seeks damages and penalties for the failure to provide meal and rest periods, and for the failure to reimburse business expenses, including, without limitation, parking and cellular telephone expenses. At this stage of the litigation, it is not feasible to predict the outcome of or a range of loss, should a loss occur, from this proceeding, and accordingly, no amounts have been provided in the accompanying financial statements. Protiviti believes it has meritorious defenses to the allegations, and Protiviti intends to continue to vigorously defend against the litigation.

The Company is involved in a number of other lawsuits arising in the ordinary course of business. While management does not expect any of these 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.

Note H—Income Taxes

The Company adopted FASB Interpretation No. 48, Accounting for Uncertainty in Income Taxes (“FIN 48”) on January 1, 2007. FIN 48 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 interpretation also provides guidance on derecognition, classification, interest and penalties, accounting in interim periods, disclosure and transition. As a result of the adoption of FIN 48, the Company recognized a $1.7 million increase in the liability for unrecognized gross tax benefits, which was accounted for as a decrease to retained earnings on January 1, 2007.

As of March 31 and January 1, 2007, the Company’s liability for unrecognized gross tax benefits totaled $13.7 million and $12.7 million, respectively, all of which, if ultimately recognized, would favorably impact the effective tax rate in future periods, net of federal tax benefit. The Company believes it is reasonably possible that the settlement of certain tax uncertainties could occur within the next twelve months; accordingly, $9.7 million of the unrecognized gross tax benefit has been classified as a current liability as of March 31, 2007. This amount primarily represents unrecognized tax benefits comprised of items related to assessed state income tax audits, as well as state and federal settlement negotiations currently in progress.

The Company’s major income tax jurisdictions are the United States and Canada. For U.S. federal income tax, the Company remains subject to examination for 2002 and subsequent years. For major U.S. states, with few exceptions, the Company remains subject to examination for 1999 and subsequent years. For Canada, the Company remains subject to examination for 2002 and subsequent years.

The Company’s continuing practice is to recognize interest and penalties related to income tax matters in income tax expense. As of March 31 and January 1, 2007, accrued interest and penalties totaled $5.4 million and $4.6 million, respectively. These amounts are recorded as components of the unrecognized gross tax benefit amounts noted above.

Note I—Stockholders’ Equity

Stock Repurchase Program. As of March 31, 2007, 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 three months ended March 31, 2007 and

12

ROBERT HALF INTERNATIONAL INC. AND SUBSIDIARIES

NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS (UNAUDITED)—(Continued)

March 31, 2007

Note I—Stockholders’ Equity (Continued)

2006, the Company repurchased approximately 2.0 million and 1.2 million shares of common stock on the open market for a total cost of $77 million and $44 million, respectively. 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. During the three months ended March 31, 2007 and 2006, such repurchases totaled approximately 0.4 million and 1.3 million shares at a cost of $15 million and $47 million, respectively. Repurchases of securities have been funded with cash generated from operations.

Repurchases of shares are applied first to the extent of retained earnings and any remaining amounts are applied to capital surplus. As a result, the Company had no retained earnings as of March 31, 2007.

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 the three months ended March 31, 2007 and 2006 (consisting of stock option exercises and the purchase of shares for the treasury) is presented in the unaudited Condensed Consolidated Statements of Stockholders’ Equity.

Note J—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.

Effective January 1, 2006, the Company adopted the fair value recognition provisions of SFAS 123(R). Under SFAS 123(R), the Company determines the fair value of stock options using the Black-Scholes valuation model. SFAS 123(R) requires the Company to recognize expense over the service period for options that are expected to vest and record adjustments to compensation expense at the end of the service period if actual forfeitures differ from original estimates.

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 receive all dividends with respect to such shares, whether or not the shares have vested. 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 a straight-line basis over the vesting period, based on the stock’s fair market value on the grant date.

Compensation cost for all restricted stock and stock units is based on the fair market value of the Company’s stock on the date of grant and is recognized over the service period. SFAS 123(R) requires that the Company recognize compensation expense for only the portion of restricted stock and stock units that is expected to vest. If the actual number of forfeitures differs from those estimated by management, additional adjustments to compensation expense may be required in future periods.

For purposes of calculating stock-based compensation expense for retirement-eligible employees, the service period is assumed to be met on the grant date or retirement-eligible date, whichever is later.

Note K—Net Income Per Share

The calculation of net income per share for the three months ended March 31, 2007 and 2006 is reflected in the following table (in thousands, except per share amounts):

The weighted average diluted common shares outstanding for the three months ended March 31, 2007 and 2006 excludes the dilutive effect of approximately 0.8 million and 0.4 million options, restricted stock and stock units, respectively. Employee stock options will have a dilutive effect under the treasury method only when the respective period’s average market value of the Company’s common stock exceeds the exercise proceeds. Under the treasury method, exercise proceeds include the amount the employee must pay for exercising stock options, the amount of compensation cost for future service that the Company has not yet recognized, and the amount of tax benefits that would be recorded in capital surplus, if the options were exercised and the restricted stock and stock units had vested. The computation of potentially dilutive shares also included unvested restricted stock and stock units.

Note L—Business Segments

The Company, which aggregates its operating segments based on the nature of services, has three reportable segments: temporary and consultant staffing, permanent placement staffing, and risk consulting and internal audit services. The temporary and consultant segment provides specialized staffing in the accounting and finance, administrative and office, information technology, legal, advertising, marketing and web design fields. 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 interest income, intangible amortization expense, and income taxes.

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. 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 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 4.1% as of March 31, 2007 and December 31, 2006. As of March 31, 2007, 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 $1.2 million. Although future results cannot always be predicted by extrapolating past results, management believes that it is reasonably likely that future results will be consistent with historical trends and experience. However, if the financial condition of the Company’s customers were to deteriorate, resulting in an impairment of their ability to make payments, or if unexpected events or significant future changes in trends were to occur, additional allowances may be required.

Income Tax Assets and Liabilities. In establishing its deferred income tax assets and liabilities, the Company makes judgments and interpretations based on the enacted tax laws and published tax guidance that are applicable to its operations. Deferred tax assets and liabilities are measured and recorded using current enacted

16

tax rates, which the Company expects will apply to taxable income in the years in which those temporary differences are recovered or settled. The likelihood of a material change in the Company’s expected realization of these assets is dependent on future taxable income, its ability to use foreign tax credit carryforwards and carrybacks, final U.S. and foreign tax settlements, and the effectiveness of its tax planning strategies in the various relevant jurisdictions.

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 our 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. In relation to actual net operating losses in certain foreign operations, valuation allowances of $12.4 million were recorded as of March 31, 2007. If such losses are ultimately utilized to offset future operating income, the Company will benefit its deferred tax assets up to the full amount of the 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, or more often if events or changes in circumstances indicate that the carrying value may not be recoverable. Impairment assessments for goodwill are done at a reporting unit level. For purposes of this assessment, the Company’s reporting units are its lines of business. In performing periodic impairment tests, the fair value of the reporting unit is compared to the carrying value, including goodwill and intangible assets. If the fair value exceeds the carrying value, there is no impairment. If the carrying value exceeds the fair value, however, an impairment condition exists.

The goodwill impairment assessment is based upon a discounted cash flow analysis. The estimate of future cash flows is based upon, among other things, a discount rate and certain assumptions about expected future operating performance. The discount rate used by management has been calculated on a consistent basis and has not fluctuated significantly. The primary assumptions related to future operating performance include revenue growth rates and expense levels. These assumptions are updated annually and are primarily based upon historical trends. Although management does not anticipate that these assumptions will change materially in the future, 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. The Company’s annual goodwill impairment analysis, which will be performed during the second quarter, is not expected to have a material effect on the financial statements. Based upon the Company’s most recent goodwill impairment analysis, management believes that unless a reporting unit were to be abandoned, the possibility of goodwill impairment as a result of a change in assumptions is unlikely.

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 $3.0 million and $4.8 million, representing 0.4% and 0.6% of applicable U.S. revenue for the three months ended March 31, 2007 and 2006, respectively.

The accrual 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

17

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 three months ended March 31, 2007, a five-percentage point deviation in the Company’s estimated loss development rates would have resulted in an increase or decrease in the allowance of $0.1 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. Effective January 1, 2006, the Company adopted the fair value recognition provisions of Statement of Financial Accounting Standards (“SFAS”) No. 123(R), Share-Based Payment (“SFAS 123(R)”). SFAS 123(R) requires the Company to recognize compensation expense for only the portion of restricted stock and stock units that is expected to vest, rather than record forfeitures when they occur. If the actual number of forfeitures differs from those estimated by management, additional adjustments to compensation expense may be required in future periods. For the three months ended March 31, 2007, compensation expense related to restricted stock and stock units was $12.3 million, of which $3.8 million was related to grants made in 2007. A one-percentage point deviation in the estimated forfeiture rates would have resulted in a $0.1 million increase or decrease in compensation expense related to restricted stock and stock units for the three months ended March 31, 2007.

Recent Accounting Pronouncements

In February 2007, the Financial Accounting Standards Board issued SFAS No. 159, The Fair Value Option for Financial Assets and Financial Liabilities (“SFAS 159”), which gives entities the option to measure eligible financial assets, and financial liabilities at fair value on an instrument by instrument basis, that are otherwise not permitted to be accounted for at fair value under other accounting standards. The election to use the fair value option is available when an entity first recognizes a financial asset or financial liability. Subsequent changes in fair value must be recorded in earnings. This statement is effective as of the beginning of a company’s first fiscal year after November 15, 2007. The Company is in the process of analyzing the impact of SFAS 159.

Results of Operations for the Three Months Ended March 31, 2007 and 2006

Temporary and consultant staffing services revenues were $868 million and $747 million for the three months ended March 31, 2007 and 2006, respectively, increasing by 16% during the three months ended March 31, 2007 compared to the same period in 2006. Permanent placement revenues were $99 million and $75 million for the three months ended March 31, 2007 and 2006, respectively, increasing by 31% during the three months ended March 31, 2007 compared to the same period in 2006. Improvement in the U.S. labor markets contributed to the increase in temporary and permanent staffing services revenues for the three months ended March 31, 2007. Risk consulting and internal audit services revenues were $130 million and $122 million for the three months ended March 31, 2007 and 2006, respectively, increasing by 7% during the three months ended March 31, 2007 compared to the same period in 2006. The 2007 increase in risk consulting and internal audit services revenues is primarily due to higher international revenues, particularly in Asia. 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 2007.

The Company’s temporary and permanent staffing services business has more than 350 offices in 42 states, the District of Columbia and 17 foreign countries, while Protiviti has more than 55 offices in 22 states and 14 foreign countries. Revenues from foreign operations represented 23% and 20% of revenues for the three months ended March 31, 2007 and 2006, 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.

18

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 $320 million and $275 million for the three months ended March 31, 2007 and 2006, respectively, increasing by 17% during the three months ended March 31, 2007 compared to the same period in 2006. Gross margin amounts equaled 37% of revenues for temporary and consultant staffing services for both the three months ended March 31, 2007 and 2006.

Gross margin dollars for the Company’s permanent placement staffing division were $99 million and $75 million for the three months ended March 31, 2007 and 2006, respectively, increasing by 31% during the three months ended March 31, 2007 compared to the same period in 2006. Gross margin dollars for the Company’s risk consulting and internal audit division were $42 million and $43 million for the three months ended March 31, 2007 and 2006, respectively, decreasing by 4% in 2007. Gross margin amounts equaled 32% and 35% of revenues for risk consulting and internal audit services for the three months ended March 31, 2007 and 2006, respectively. The 2007 decrease in gross margin percentage is primarily the result of lower utilization of the professional staff in the United States as well as the addition of professional staff related to the expansion of international operations.

Selling, general and administrative expenses were $348 million in the three months ended March 31, 2007, compared to $287 million in the same period in 2006. Selling, general and administrative expenses as a percentage of revenues were 32% and 30% for the three months ended March 31, 2007 and 2006, respectively. Selling, general and administrative expenses consist primarily of staff compensation, advertising, depreciation and occupancy costs. The higher mix of permanent placement activities and the continuing additions to professional staff all contributed to the higher percentage of 2007 selling, general and administrative expenses.

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’s annual goodwill impairment analysis, which is not expected to have a material effect on the financial statements, will be performed in the second quarter. Net intangible assets, consisting primarily of goodwill, represented 12% of total assets and 17% of total stockholders’ equity at March 31, 2007.

Interest income for the three months ended March 31, 2007 and 2006 was $5.1 million and $4.1 million, respectively. The higher 2007 interest income resulted from higher interest rates offset by slightly lower average cash balances. Interest expense for the three months ended March 31, 2007 and 2006 was $1.1 million and $0.6 million, respectively.

The provision for income taxes was 39% and 40% of income before taxes for the three months ended March 31, 2007 and 2006, respectively. The lower 2007 provision percentage is primarily the result of various federal income tax credits.

Liquidity and Capital Resources

The change in the Company’s liquidity during the three months ended March 31, 2007 and 2006 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.

Cash, and cash equivalents were $450 million and $473 million at March 31, 2007 and 2006, respectively. Operating activities provided $114 million during the three months ended March 31, 2007, partially offset by $27 million and $86 million of net cash used in investing activities and financing activities, respectively. Operating activities provided $101 million during the three months ended March 31, 2006, partially offset by $31 million and $57 million of net cash used in investing activities and financing activities, respectively.

19

Operating activities—Net cash provided by operating activities for the three months ended March 31, 2007 was composed of net income of $71 million adjusted for non-cash items of $42 million, and net cash provided by changes in working capital of $1 million. Net cash provided by operating activities for the three months ended March 31, 2006 was composed of net income of $65 million adjusted for non-cash items of $21 million, and net cash provided by changes in working capital of $15 million.

Investing activities—Cash used in investing activities for the three months ended March 31, 2007 was $27 million. This was primarily composed of capital expenditures of $24 million and deposits to trusts for employee benefits and retirement plans of $3 million. Cash used in investing activities for the three months ended March 31, 2006 was $31 million. This was primarily composed of capital expenditures of $24 million and purchases of goodwill and other assets of $6 million.

Financing activities—Cash used in financing activities for the three months ended March 31, 2007 was $86 million. This included repurchases of $92 million in common stock and $17 million in cash dividends to stockholders, partially offset by proceeds of $15 million from exercises of stock options and the excess tax benefits from stock-based compensation of $8 million. Cash used in financing activities for the three months ended March 31, 2006 was $57 million. This included repurchases of $91 million in common stock and $14 million in cash dividends to stockholders, partially offset by proceeds of $29 million from exercises of stock options and the excess tax benefits from stock-based compensation of $19 million.

As of March 31, 2007, 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 three months ended March 31, 2007 and 2006, the Company repurchased approximately 2.0 million and 1.2 million shares of common stock on the open market for a total cost of $77 million and $44 million, respectively. 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. During the three months ended March 31, 2007 and 2006, such repurchases totaled approximately 0.4 million and 1.3 million shares at a cost of $15 million and $47 million, respectively. Repurchases of securities have been funded with cash generated from operations.

The Company’s working capital at March 31, 2007 included $450 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 May 3, 2007, the Company announced a quarterly dividend of $0.10 per share to be paid to all shareholders of record on May 25, 2007. The dividend will be paid on June 15, 2007.

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 three months ended March 31, 2007, approximately 23% 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, particularly the Canadian dollar, British pound, and Euro, 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.

20

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.

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.

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 last fiscal quarter that has materially affected, or is reasonably likely to materially affect, the Company’s internal control over financial reporting.
