Accounting Policies [Abstract]
Basis of Presentation and Accounting Policies	Basis of Presentation and Accounting Policies Basis of Presentation Certain information and footnote disclosures normally included in the financial statements prepared in accordance with United States Generally Accepted Accounting Principles ("GAAP") have been condensed or omitted pursuant to the rules and regulations of the Securities and Exchange Commission, although we believe that the disclosures are adequate to make the information presented not misleading. These Consolidated Financial Statements should be read in conjunction with the Consolidated Financial Statements included in our 2017 Annual Report on Form 10-K. The information furnished reflects all adjustments that, in the opinion of management, were necessary for a fair statement of the Consolidated Financial Statements for the periods presented. Such adjustments were of a normal recurring nature, unless otherwise disclosed. Payroll Tax Credit In March 2017, we sold a portion of our French payroll tax credits earned in 2016 for net proceeds of $143.5 ( €133.0 ). We derecognized these receivables upon the sale date as the terms of the agreement are such that the transaction qualifies for sale treatment according to the accounting guidance on the transfer and servicing of assets. The discount on the sale of these receivables was recorded in cost of services as a reduction of the payroll tax credits. Subsequent Events On April 4, 2018, we sold substantially all of our French payroll tax credits earned in 2017 for net proceeds of $234.5 ( €190.9 ). We derecognized these receivables upon the sale date as the terms of the agreement are such that the transaction qualifies for sale treatment according to the accounting guidance on the transfer and servicing of assets. The discount on the sale of these receivables was recorded in cost of services as a reduction of the payroll tax credits. We have evaluated all other events and transactions occurring after the balance sheet date through our filing date and have accrued or disclosed, if appropriate.

New Accounting Pronouncements and Changes in Accounting Principles [Abstract]
Recently Issued Accounting Standards	Recently Issued Accounting Standards In February 2016, the FASB issued new accounting guidance on leases. The new guidance requires that a lessee recognize assets and liabilities on the balance sheet for leases with lease terms longer than 12 months. The recognition, measurement and presentation of lease expenses and cash flows by a lessee will depend on its classification as a finance or operating lease. The guidance also includes new disclosure requirements providing information on the amounts recorded in the financial statements. The new guidance is effective for us in 2019. We are currently assessing the impact of the adoption of this guidance on our Consolidated Financial Statements. In August 2017, the FASB issued new guidance on hedge accounting. The amendments in this guidance include the elimination of the concept of recognizing periodic hedge ineffectiveness for cash flow and net investment hedges, recognition and presentation of changes in the fair value of the hedging instrument, recognition and presentation of components excluded from an entity's hedge effectiveness assessment, addition of the ability to elect to perform subsequent effectiveness assessments qualitatively, and addition of new disclosure requirements. The guidance is effective for us in 2019. We are currently assessing the impact of the adoption of this guidance on our Consolidated Financial Statements. In February 2018, the FASB issued new guidance on reporting comprehensive income. The new guidance allows a reclassification from accumulated other comprehensive income to retained earnings for stranded tax effects resulting from the United States Tax Cuts and Jobs Act of 2017 (the "Tax Act"). The guidance is effective for us in 2019. We are currently assessing the impact of the adoption of this guidance on our Consolidated Financial Statements.

Revenue Recognition

Revenue from Contract with Customer [Abstract]
Revenue Recognition	Revenue Recognition Adoption of New Accounting Guidance on Revenue Recognition As of January 1, 2018 , we adopted the new accounting guidance on revenue recognition using the modified retrospective approach applied to those contracts that were not completed as of January 1, 2018. Results for reporting periods beginning after January 1, 2018 are presented under the new guidance, while prior periods continue to be reported in accordance with previous accounting guidance. We determined that no cumulative effect adjustment to retained earnings was necessary upon adoption as there were no significant revenue recognition differences identified between the new and previous accounting guidances. Revenue Recognition We recognize revenue when control of the promised services is transferred to our clients, in an amount that reflects the consideration we expect to be entitled to receive in exchange for those services. Our revenues are recorded net of any sales, value added, or other taxes collected from our clients. A performance obligation is a promise in a contract to transfer a distinct service to the client and is the unit of account in the new accounting guidance for revenue recognition. The majority of our contracts have a single performance obligation as the promise to transfer the individual services is not separately identifiable from other promises in our contracts and, therefore, not distinct. However, we do have multiple performance obligations within our Recruitment Process Outsourcing (RPO) contracts as discussed below. For performance obligations that we satisfy over time, revenue is recognized by consistently applying a method of measuring progress toward satisfaction of that performance obligation. We generally utilize an input measure of time (e.g., hours, weeks, months) of service provided, which most accurately depicts the progress toward completion of each performance obligation. We generally determine standalone selling prices based on the prices included in the client contracts, using expected cost plus margin, or other observable prices. The price as specified in our client contracts is generally considered the standalone selling price as it is an observable input that depicts the price as if sold to a similar client in similar circumstances. Certain client contracts have variable consideration, including credits, sales allowances, rebates or other similar items that generally reduce the transaction price. We estimate variable consideration using whichever method, either the expected value method or most likely amount method, better predicts the amount of consideration to which we will become entitled based on the terms of the client contract and historical evidence. These amounts may be constrained and are only included in revenue to the extent we do not expect a significant reversal when the uncertainty associated with the variable consideration is resolved. Our variable consideration amounts are not material and we do not believe that there will be significant changes to our estimates. Our client contracts generally include standard payment terms acceptable in each of the countries and territories in which we operate. The payment terms vary by the type and location of our clients and services offered. Client payments are typically due approximately 60 days after invoicing, but may be a shorter or longer term depending on the contract. Our client contracts are generally short-term in nature with a term of one year or less. The timing between satisfaction of the performance obligation, invoicing and payment is not significant. For certain services and client types, we may require payment prior to delivery of services to the client, for which deferred revenue is recorded. Principal vs. Agent In certain scenarios where a third-party vendor is involved in our revenue transactions with our clients, we evaluate whether we are the principal or the agent in the transaction. In situations where we act as a principal in the transaction, we control the performance obligation prior to transfer to the client and we report the related amounts as gross revenues and cost of services. When we act as an agent, we do not control the performance obligation prior to transfer to the client and we report the related amounts as revenues on a net basis. A majority of these transactions occur within our TAPFIN - Managed Service Provider (MSP) programs where our performance obligation is to manage our client’s contingent workforce and we earn a commission based on the amount of staffing services that are managed through the program. We are the agent in these transactions as we do not control the third-party providers staffing services provided to the client through our MSP program prior to those services being transferred to the client. Practical Expedients and Exemptions For certain client contracts for which we recognize revenue over time, we recognize the amount that we have the right to invoice which corresponds directly to the value to the client of our performance to date. As allowed under the new guidance, we do not disclose the amount of unsatisfied performance obligations for client contracts with an original expected length of one year or less and those client contracts for which we recognize revenue at the amount to which we have the right to invoice for services performed. We have other contracts with revenues expected to be recognized subsequent to March 31, 2018 related to remaining performance obligations which are not material. Disaggregation of Revenues In the following table, revenue is disaggregated by service types and timing of revenue recognition, and includes a reconciliation of the disaggregated revenues by reportable segment. 3 Months Ended March 31, 2018 Service Types Americas Southern Europe Northern Europe APME Right Management Total Staffing and Interim $ 931.4 $ 2,110.3 $ 1,255.2 $ 599.2 $ — $ 4,896.1 Outcome-Based Solutions and Consulting 40.5 148.3 109.8 68.4 11.5 378.5 Permanent Recruitment 27.8 38.6 44.5 49.0 — 159.9 Other 22.9 14.8 8.1 3.6 38.5 87.9 $ 1,022.6 $ 2,312.0 $ 1,417.6 $ 720.2 $ 50.0 $ 5,522.4 3 Months Ended March 31, 2018 Timing of Revenue Recognition Americas Southern Europe Northern Europe APME Right Management Total Services transferred over time $ 1,006.4 $ 2,276.5 $ 1,379.2 $ 688.9 $ 50.0 $ 5,401.0 Services transferred at a point in time 16.2 35.5 38.4 31.3 — 121.4 $ 1,022.6 $ 2,312.0 $ 1,417.6 $ 720.2 $ 50.0 $ 5,522.4 Revenue Service Types The following is a description of our revenue service types, including Staffing and Interim, Outcome-Based Solutions and Consulting, Permanent Recruitment and Other services. Staffing and Interim Staffing and Interim services include the augmentation of clients’ workforce with our contingent employees performing services under the client’s supervision, which provides our clients with a source of flexible labor. Staffing and Interim client contracts are generally short-term in nature and we generally enter into contracts that include only a single performance obligation. We recognize revenue over time based on a fixed amount for each hour of Staffing and Interim service provided as our clients benefit from our services as we provide them. Outcome-Based Solutions and Consulting Our Outcome-Based Solutions and Consulting services include utilizing consultants and contingent employees who are generally experts in a specific field advising the client to help find strategic solutions to specific matters or achieve a particular outcome. Our services may also include managing certain processes and functions within the client’s organization. We recognize revenue over time based on (i) our clients benefiting from our services as we are providing them, (ii) our clients controlling the asset as it is created or enhanced (e.g., when a printer is fixed at the client site), or (iii) because our performance does not create an asset with an alternative use and we have an enforceable right to payment for the services we have provided to date. We generally utilize an input measure of time of service provided, which most accurately depicts the progress toward completion of these performance obligations. The price as specified in our client contracts is generally considered the standalone selling price as it is an observable input which depicts the price as if sold to a similar client in similar circumstances. Permanent Recruitment Permanent Recruitment services include providing qualified candidates to our clients to hire on a permanent basis. We recognize revenues for our Permanent Recruitment services at a point in time when we place the qualified candidate, because we have determined that control has transferred to the client as we have the right to payment for our service and the client has accepted our service of providing a qualified candidate to fill a permanent position. Revenues recognized from our Permanent Recruitment services are based upon either a fixed fee per placement or as a percentage of the candidate’s salary. Our RPO services are also included in our Permanent Recruitment revenues. RPO services include the various activities of managing a client's permanent workforce, which can include candidate assessments, screening, conducting candidate interviews, providing sourcing technology, and providing our marketing and recruiting expertise. We perform these activities to fulfill the overall promise of permanent workforce management, so they are not individually distinct and therefore we account for them as a single performance obligation. We generally utilize an input measure of time of months, but we do have a few contracts for which we use labor hours of management service provided as this most accurately depicts the progress toward completion of the performance obligation. We recognize revenue over time for each month of management services provided, as each month of services is distinct and the client benefits from each month of service as we provide it. We consider the RPO management services and placement services to be distinct and, thus, separate performance obligations within our RPO contracts as (i) our clients can benefit from each service on its own and (ii) each service is separately identifiable within the client contract. The prices as specified in our contracts will generally be broken out between management fees and placement fees, for which we consider the standalone selling price of each service as they are the observable inputs which depict the prices as if they were sold to a similar client in similar circumstances. The consideration from our client contracts is allocated to each performance obligation based on the relative standalone selling price. Other Services Other services include revenues from outplacement services, MSP services, training services and franchise fees. • Outplacement services include assisting our clients in managing their workforce transitions and their employees in managing career changes by developing additional skills and finding new employment. We recognize revenue over time as we transfer control of the performance obligation using the input measure of hours of service to measure progress toward completion of the performance obligation. • MSP services include overall program management of our clients’ contingent workforce and generally include various activities such as reporting and tracking, supplier selection and management and order distribution depending on each client contract. We provide these services to fulfill the overall promise of contingent workforce management so the individual activities are not distinct and therefore we account for them as a single performance obligation. We recognize revenue over time for each month of MSP services provided, as each month of services is distinct and the client benefits from each month of services as we provide it. • Training services include teaching skills that relate to specific competencies in order for our client’s workforce to acquire knowledge and develop skills proficiencies. We recognize revenue over time for each hour of training service provided as our clients benefit from our services as we provide them. • Our franchise fees include the performance obligation of providing the right to use our intellectual property in a specifically defined exclusive territory as defined in a franchise agreement. Our franchise agreements generally state that franchise fees are calculated based on a percentage of revenues earned by the franchise operations and are payable on a monthly basis. As such, we record franchise fee revenues monthly over time calculated based on the specific fee percentage and the monthly revenues of the franchise operations. Accounts Receivable, Contract Assets and Contract Liabilities We record accounts receivable when our right to consideration becomes unconditional. Contract assets primarily relate to our rights to consideration for services provided that they are conditional on satisfaction of future performance obligations. We record contract liabilities (deferred revenue) when payments are made or due prior to the related performance obligations being satisfied. The current portion of our contract liabilities is included in accrued liabilities in our Consolidated Balance Sheets. We do not have any material contract assets or long-term contract liabilities. Our deferred revenue was $35.9 at March 31, 2018 and $48.0 at December 31, 2017 . The decrease is due to $20.9 of revenues recognized related to amounts that were included in the December 31, 2017 balance, partially offset by payments or amounts due in advance of satisfying our performance obligations in the first quarter of 2018.

The expense relates to stock options, deferred stock, restricted stock and performance share units. We recognize share-based compensation expense in selling and administrative expenses on a straight-line basis over the service period of each award. Consideration received from share-based awards was $3.6 and $34.4 for the three months ended March 31, 2018 and 2017 , respectively. Our annual grant of share-based compensation generally takes place during the first quarter of each fiscal year.

Business Combinations [Abstract]
Acquisitions	Acquisitions From time to time, we acquire and invest in companies throughout the world, including franchises. For the three months ended March 31, 2018 , the total cash consideration for acquisitions, net of cash acquired, was $41.0 , the majority of which took place in the Netherlands. This balance includes initial acquisition payments of $8.2 and contingent consideration payments of $32.8 ( $8.7 of which was recognized as a liability at the acquisition date). During the three months ended March 31, 2017, the total cash consideration for acquisitions, net of cash acquired, was $24.6 , which includes initial acquisition payments of $11.7 and contingent consideration related to previous acquisitions of $12.9 , of which $10.3 was related to our 2015 acquisition of 7S Group GmbH ("7S") in Germany. On April 26, 2017, the sellers of 7S formally disputed the contingent consideration related to the acquisition and are claiming an additional $25.6 ( €20.8 ), plus interest. We believe no further amounts are due and intend to vigorously dispute their claims in arbitration. We are not currently able to predict the outcome of the arbitration or the timing of any resolution, and consequently, no amounts have been recorded in the Consolidated Financial Statements. As of January 1, 2018, we adopted the new accounting guidance on statement of cash flows. The guidance provides classification requirements for certain cash receipts and cash payments. During the first quarter of 2018, we classified $24.1 of payments which were in excess of the contingent consideration liabilities recognized on the acquisition date as operating cash flows. The excess cash payments for contingent consideration liabilities made during the first quarter of 2017 were not material.

Income Tax Disclosure [Abstract]
Income Taxes	Income Taxes We recorded income tax expense at an effective rate of 29.6% for the three months ended March 31, 2018 , as compared to an effective rate of 33.6% for the three months ended March 31, 2017 . The 2018 rate was favorably impacted by the enactment of the Tax Act in December 2017. The 29.6% effective tax rate in the quarter was higher than the United States Federal statutory rate of 21% primarily due to the French business tax. We currently expect a 2018 annual effective tax rate of approximately 27% to 28% . The Tax Act made broad changes to the United States tax code including a reduction of the United States federal corporate income tax rate from 35% to 21% effective January 1, 2018 and a transition to a territorial tax regime resulting in a one-time transition tax on the mandatory deemed repatriation of unremitted post-1986 non-United States earnings. The Tax Act also established new provisions related to global intangible low-taxed income ("GILTI"), foreign derived intangible income and a base erosion and anti-abuse tax. The computation of these new provisions is highly complex, and our estimates could significantly change as a result of new rules or guidance from the various standard-setting bodies. Our accounting for certain elements of the Tax Act was incomplete as of December 31, 2017 , and remains incomplete as of March 31, 2018 . However, we were able to make reasonable estimates of the impact of the Tax Act as of December 31, 2017 and, therefore, recorded provisional estimates for these items, including the one-time transition tax and the revaluation of our deferred tax assets and liabilities. In accordance with accounting guidance, we are allowed to make an accounting policy choice to either treat taxes due on future inclusions in United States taxable income related to GILTI as a current-period expense when incurred or factor in such amounts into our measurement of deferred taxes. We have not made a policy decision regarding whether to record deferred taxes on GILTI and have included estimates of this provision as period costs for the three months ended March 31, 2018 . During the first three months of 2018, the Internal Revenue Service issued new guidance affecting the computation of our 2017 transition tax liability. As a result of the new guidance and additional analysis of the impacts of the Tax Act, we revised our provisional estimates and recorded a tax benefit of $2.1 related to the Tax Act during the period ended March 31, 2018. The ultimate impact of the Tax Act may differ from our estimates at March 31, 2018, possibly materially, due to changes in interpretations and assumptions we have made, future guidance that may be issued and actions we may take as a result of the Tax Act. As of March 31, 2018 , we had gross unrecognized tax benefits related to various tax jurisdictions, including interest and penalties, of $68.0 that would favorably impact the effective tax rate if recognized. As of December 31, 2017 , we had gross unrecognized tax benefits related to various tax jurisdictions, including interest and penalties, of $66.5 . We do not expect our unrecognized tax benefits to change significantly over the next 12 months. We conduct business globally in various countries and territories. We are routinely audited by the tax authorities of the various tax jurisdictions in which we operate. Generally, the tax years that could be subject to examination are 2010 through 2017 for our major operations in France, Germany, Japan, the United Kingdom and the United States. As of March 31, 2018 , we are subject to tax audits in Austria, Canada, Denmark, France, Germany and the United States. We believe that the resolution of these audits will not have a material impact on earnings.

During 2018 , we expect to make total contributions of approximately $12.1 to our pension plans and to fund our retiree health care payments as incurred. As of January 1, 2018, we adopted the new guidance on the presentation of net periodic pension and postretirement benefit cost ("net benefit cost"). The new guidance requires bifurcation of net benefit cost, which used to be reported as an employee cost within operating income under the old guidance. The service cost component is still presented with other employee compensation cost in operating income or capitalized in assets in rare circumstances. The other components are now reported separately outside of operations, and are not eligible for capitalization. We have reclassified the 2017 non-service cost components of net benefit cost to interest and other expenses from selling and administrative expenses to conform to the current period presentation. For the three months ended March 31, 2018 and 2017, the non-service component was a cost of $0.5 and $0.9 , respectively. For the year ended December 31, 2017, the non-service component was a cost of $1.0 .

Shareholders' Equity	Shareholders’ Equity The components of accumulated other comprehensive loss, net of tax, were as follows: March 31, December 31, 2018 2017 Foreign currency translation $ (40.0 ) $ (87.7 ) Translation loss on net investment hedge, net of income taxes of $(27.9) and $(23.1), respectively (56.3 ) (39.9 ) Translation loss on long-term intercompany loans (121.2 ) (128.8 ) Unrealized gain on investments, net of income taxes of $3.4 for 2017 — 15.3 Defined benefit pension plans, net of income taxes of $(27.6) and $(27.8), respectively (49.9 ) (50.5 ) Retiree health care plan, net of income taxes of $2.0 for both 2018 and 2017 3.3 3.4 Accumulated other comprehensive loss $ (264.1 ) $ (288.2 ) As of January 1, 2018, we adopted the new accounting guidance on financial instruments. The new guidance requires equity investments (except those accounted for under the equity method of accounting or those that result in consolidation of the investee) to be measured at fair value with changes in fair value recognized in net earnings. Upon adoption, we reclassified $15.3 , the cumulative unrealized gain on our Swiss franchise's investment portfolio as of December 31, 2017, from accumulated other comprehensive loss to retained earnings. Going forward, we will recognize all the changes in fair value on the investment portfolio in the current period earnings as opposed to other comprehensive loss. Noncontrolling Interests Noncontrolling interests, included in total shareholders' equity in our Consolidated Balance Sheets, represent amounts related to majority-owned subsidiaries for which we have a controlling financial interest. Net earnings attributable to these noncontrolling interests were $1.2 and $2.2 for the three months ended March 31, 2018 and 2017 , respectively, which were presented as expenses in interest and other expenses in our Consolidated Statements of Operations. Dividends On May 4, 2018 and May 2, 2017 , the Board of Directors declared a semi-annual cash dividend of $1.01 and $0.93 per share, respectively. The 2018 dividends will be payable on June 15, 2018 to shareholders of record on June 1, 2018 . The 2017 dividends were paid on June 15, 2017 to shareholders of record on June 1, 2017 . Share Repurchases In July 2016, the Board of Directors authorized the repurchase of 6.0 million shares of our common stock. Share repurchases may be made from time to time through a variety of methods, including open market purchases, block transactions, privately negotiated transactions or similar facilities. During the first quarter of 2018 , we repurchased 0.4 million shares at a cost of $ 50.1 . During the first quarter of 2017 , we repurchased 0.6 million shares at a cost of $57.0 . As of March 31, 2018 , there were 2.4 million shares remaining authorized for repurchase.

Derivative Instruments and Hedging Activities Disclosure [Abstract]
Derivative Financial Instruments and Fair Value Measurements	Derivative Financial Instruments and Fair Value Measurements We are exposed to various risks relating to our ongoing business operations. Among these risks are foreign currency exchange rate risk and interest rate risk, which can be managed through the use of derivative instruments. In certain circumstances, we enter into foreign currency forward exchange contracts (“forward contracts”) to reduce the effects of fluctuating foreign currency exchange rates on our cash flows denominated in foreign currencies. Our exposure to market risk for changes in interest rates relates primarily to our long-term debt obligations. We have historically managed interest rate risk through the use of a combination of fixed and variable rate borrowings. In accordance with the current accounting guidance on derivative instruments and hedging activities, we record all of our derivative instruments as either an asset or liability measured at their fair value. A portion of the €400.0 ( $490.7 ) notes due September 2022 and the €350.0 ( $431.3 ) notes due June 2018 was designated as a hedge of our net investment in our foreign subsidiaries with a Euro-functional currency as of March 31, 2018 . For this portion of the Euro-denominated notes, the gain or loss associated with foreign currency translation is recorded as a component of accumulated other comprehensive loss, net of taxes. As of March 31, 2018 and December 31, 2017 , we had an unrealized loss of $(52.1) and $(35.7) , respectively, included in accumulated other comprehensive loss, net of taxes, as the net investment hedge was deemed effective. On occasion, forward contracts are designated as a hedge of our net investment in our foreign subsidiaries. We had a translation loss of $(4.2) as of both March 31, 2018 and December 31, 2017 , included in accumulated other comprehensive loss, net of taxes, as the net investment hedge was deemed effective. For our forward contracts that are not designated as hedges, any gain or loss resulting from the change in fair value is recognized in the current period earnings. These gains or losses are offset by the exposure related to receivables and payables with our foreign subsidiaries and to interest due on our Euro-denominated notes, which is paid annually in June and September. For the three months ended March 31, 2018 and 2017 , we recorded no gain and a gain of $0.1 , respectively, in interest and other expenses associated with those forward contracts, which offset the loss and gain recorded for the items noted above. The fair value measurements of those items recorded in our Consolidated Balance Sheets as of March 31, 2018 and December 31, 2017 were as follows: Fair Value Measurements Using March 31, Quoted Prices in Active Markets for Identical Assets (Level 1) Significant Other Observable Inputs (Level 2) Significant Unobservable Inputs (Level 3) Assets Deferred compensation plan assets $ 100.0 $ 100.0 $ — $ — $ 100.0 $ 100.0 $ — $ — Fair Value Measurements Using December 31, Quoted Prices in Active Markets for Identical Assets (Level 1) Significant Other Observable Inputs (Level 2) Significant Unobservable Inputs (Level 3) Assets Deferred compensation plan assets $ 99.1 $ 99.1 $ — $ — $ 99.1 $ 99.1 $ — $ — Liabilities Foreign currency forward contracts $ 0.1 $ — $ 0.1 $ — $ 0.1 $ — $ 0.1 $ — We determine the fair value of our deferred compensation plan assets, comprised of publicly traded securities, by using market quotes as of the last day of the period. The fair value of the foreign currency forward contracts is measured at the value from either directly or indirectly observable inputs from third parties. The carrying value of long-term debt approximates fair value, except for the Euro-denominated notes. The fair value of the Euro-denominated notes, as observable at commonly quoted intervals (level 2 inputs), was $958.6 and $939.9 as of March 31, 2018 and December 31, 2017 , respectively, compared to a carrying value of $921.9 and $897.8 , respectively.

Segment Data

Segment Reporting [Abstract]
Segment Data	Segment Data Effective January 1, 2018, we adopted new accounting guidance on the presentation of net benefit cost. Under the new guidance, we are required to present non-service cost components of net benefit cost in interest and other expenses, as opposed to selling and administrative expenses. All previously reported results have been restated to conform to the current year presentation. We are organized and managed primarily on a geographic basis, with Right Management currently operating as a separate global business unit. Each country and business unit generally has its own distinct operations and management team, providing services under our global brands, and maintains its own financial reports. We have an executive sponsor for each global brand who is responsible for ensuring the integrity and consistency of delivery locally. Each operation reports directly or indirectly through a regional manager, to a member of executive management. Given this reporting structure, all of our operations have been segregated into the following reporting segments: Americas, which includes United States and Other Americas; Southern Europe, which includes France, Italy and Other Southern Europe; Northern Europe; APME; and Right Management. The Americas, Southern Europe, Northern Europe and APME segments derive a significant majority of their revenues from our staffing and interim services. The remaining revenues within these segments are derived from our outcome-based solutions and consulting services, permanent recruitment services and other services. The Right Management segment revenues are derived from outplacement and talent management services. Segment revenues represent sales to external clients. We provide services to a wide variety of clients, none of which individually comprise a significant portion of revenues for us as a whole. Due to the nature of our business, we generally do not have export sales. 3 Months Ended March 31, 2018 2017 Revenues from services: Americas: United States (a) $ 616.3 $ 661.5 Other Americas 406.3 364.7 1,022.6 1,026.2 Southern Europe: France 1,424.0 1,137.5 Italy 413.6 294.4 Other Southern Europe 474.4 372.0 2,312.0 1,803.9 Northern Europe 1,417.6 1,238.7 APME 720.2 632.4 Right Management 50.0 56.0 Consolidated (b) $ 5,522.4 $ 4,757.2 Operating unit profit: (c) Americas: United States $ 26.7 $ 26.3 Other Americas 16.2 12.4 42.9 38.7 Southern Europe: France 57.7 50.6 Italy 25.2 18.2 Other Southern Europe 14.8 12.7 97.7 81.5 Northern Europe 16.6 11.8 APME 25.9 20.1 Right Management 6.4 8.8 189.5 160.9 Corporate expenses (26.8 ) (24.6 ) Intangible asset amortization expense (8.9 ) (8.4 ) Operating profit 153.8 127.9 Interest and other expenses (16.1 ) (15.8 ) Earnings before income taxes $ 137.7 $ 112.1 (a) In the United States, where a majority of our franchises operate, revenues from services included fees received from the related franchise offices of $3.2 and $3.5 for the three months ended March 31, 2018 and 2017 , respectively. These fees are primarily based on revenues generated by the franchise offices, which were $149.0 and $167.7 for the three months ended March 31, 2018 and 2017 , respectively. (b) Our consolidated revenues from services include fees received from our franchise offices of $5.2 and $5.3 for the three months ended March 31, 2018 and 2017 , respectively. These fees are primarily based on revenues generated by the franchise offices, which were $236.8 and $239.1 for the three months ended March 31, 2018 and 2017 , respectively. (c) We evaluate segment performance based on operating unit profit (“OUP”), which is equal to segment revenues less cost of services and branch and national headquarters operating costs. This profit measure does not include goodwill and intangible asset impairment charges or amortization of intangibles related to acquisitions, corporate expenses, interest and other income and expense amounts or income taxes.

These Consolidated Financial Statements should be read in conjunction with the Consolidated Financial Statements included in our 2017 Annual Report on Form 10-K. The information furnished reflects all adjustments that, in the opinion of management, were necessary for a fair statement of the Consolidated Financial Statements for the periods presented. Such adjustments were of a normal recurring nature, unless otherwise disclosed. Payroll Tax Credit In March 2017, we sold a portion of our French payroll tax credits earned in 2016 for net proceeds of $143.5 ( €133.0 ). We derecognized these receivables upon the sale date as the terms of the agreement are such that the transaction qualifies for sale treatment according to the accounting guidance on the transfer and servicing of assets. The discount on the sale of these receivables was recorded in cost of services as a reduction of the payroll tax credits. Subsequent Events On April 4, 2018, we sold substantially all of our French payroll tax credits earned in 2017 for net proceeds of $234.5 ( €190.9 ). We derecognized these receivables upon the sale date as the terms of the agreement are such that the transaction qualifies for sale treatment according to the accounting guidance on the transfer and servicing of assets. The discount on the sale of these receivables was recorded in cost of services as a reduction of the payroll tax credits. We have evaluated all other events and transactions occurring after the balance sheet date through our filing date and have accrued or disclosed, if appropriate.

New Accounting Pronouncements and Changes in Accounting Principles [Abstract]
Recently Issued Accounting Standards	Recently Issued Accounting Standards In February 2016, the FASB issued new accounting guidance on leases. The new guidance requires that a lessee recognize assets and liabilities on the balance sheet for leases with lease terms longer than 12 months. The recognition, measurement and presentation of lease expenses and cash flows by a lessee will depend on its classification as a finance or operating lease. The guidance also includes new disclosure requirements providing information on the amounts recorded in the financial statements. The new guidance is effective for us in 2019. We are currently assessing the impact of the adoption of this guidance on our Consolidated Financial Statements. In August 2017, the FASB issued new guidance on hedge accounting. The amendments in this guidance include the elimination of the concept of recognizing periodic hedge ineffectiveness for cash flow and net investment hedges, recognition and presentation of changes in the fair value of the hedging instrument, recognition and presentation of components excluded from an entity's hedge effectiveness assessment, addition of the ability to elect to perform subsequent effectiveness assessments qualitatively, and addition of new disclosure requirements. The guidance is effective for us in 2019. We are currently assessing the impact of the adoption of this guidance on our Consolidated Financial Statements. In February 2018, the FASB issued new guidance on reporting comprehensive income. The new guidance allows a reclassification from accumulated other comprehensive income to retained earnings for stranded tax effects resulting from the United States Tax Cuts and Jobs Act of 2017 (the "Tax Act"). The guidance is effective for us in 2019. We are currently assessing the impact of the adoption of this guidance on our Consolidated Financial Statements.
