Accounting Policies [Abstract]
Summary of Significant Accounting Policies	Summary of Significant Accounting Policies Nature of Operations ManpowerGroup Inc. is a world leader in the innovative workforce solutions and services industry. Our global network of over 2,900 offices in 80 countries and territories allows us to meet the needs of our global, multinational and local clients across all major industry segments. Our largest operations, based on revenues, are located in the United States, France, Italy and the United Kingdom. We specialize in permanent, temporary and contract recruitment and assessment; training and development; outsourcing; career management and workforce consulting services. We provide services to a wide variety of clients, none of which individually comprise a significant portion of revenues for us as a whole. Use of Estimates The preparation of financial statements in conformity with accounting principles generally accepted in the United States requires us 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 for the reporting period. Actual results could differ from these estimates. Basis of Consolidation The Consolidated Financial Statements include our operating results and the operating results of all of our majority-owned subsidiaries and entities in which we have a controlling financial interest. We have a controlling financial interest if we own a majority of the outstanding voting common stock and the noncontrolling shareholders do not have substantive participating rights, or we have significant control over an entity through contractual or economic interests in which we are the primary beneficiary. For subsidiaries in which we have an ownership interest of 50% or less, but more than 20%, the Consolidated Financial Statements reflect our ownership share of those earnings using the equity method of accounting. These investments, as well as certain other relationships, are also evaluated for consolidation under the accounting guidance on consolidation of variable interest entities. These investments were $137.9 and $132.3 as of December 31, 2015 and 2014 , respectively, and are included in other assets in the Consolidated Balance Sheets. Included in shareholders’ equity as of December 31, 2015 and 2014 are $85.4 and $77.4 , respectively, of unremitted earnings from investments accounted for using the equity method. All significant intercompany accounts and transactions have been eliminated in consolidation. Revenues and Receivables We generate revenues from sales of services by our company-owned branch operations and from fees earned on sales of services by our franchise operations. Revenues are recognized as services are performed. The majority of our revenues are generated by our recruitment business, where billings are generally negotiated and invoiced on a per-hour basis. Accordingly, as contingent workers are placed, we record revenues based on the hours worked. Permanent recruitment revenues are recorded as placements are made. Provisions for sales allowances, based on historical experience, are recognized at the time the related sale is recognized. Our franchise agreements generally state that franchise fees are calculated based on a percentage of revenues. We record franchise fee revenues monthly based on the amounts due under the franchise agreements for that month. Franchise fees, which are included in revenues from services, were $24.2 , $25.4 and $24.4 for the years ended December 31, 2015 , 2014 and 2013 , respectively. In our outplacement business, we recognize revenues from individual programs and for large projects over the estimated period in which services are rendered to candidates. In our consulting business, revenues are recognized upon the performance of the service under the consulting service contract. For performance-based contracts, we defer recognizing revenues until the performance criteria have been met. The amounts billed for outplacement, consulting services and performance-based contracts in excess of the amount recognized as revenues are recorded as deferred revenue and included in accrued liabilities for the current portion and other long-term liabilities for the long-term portion in our Consolidated Balance Sheets. As of December 31, 2015 and 2014 , deferred revenue was $38.4 and $35.5 , respectively, all of which was current. W e record revenues from sales of services and the related direct costs in accordance with the accounting guidance on reporting revenue gross as a principal versus net as an agent. In situations where we act as a principal in the transaction, we report gross revenues and cost of services. When we act as an agent, we report the revenues on a net basis. Amounts billed to clients for out-of-pocket or other cost reimbursements are included in revenues from services, and the related costs are included in cost of services. Allowance for Doubtful Accounts We have an allowance for doubtful accounts recorded as an estimate of the accounts receivable balance that may not be collected. This allowance is calculated on an entity-by-entity basis with consideration for historical write-off experience, the current aging of receivables and a specific review for potential bad debts. Items that affect this balance mainly include bad debt expense and the write-off of accounts receivable balances. Bad debt expense is recorded as selling and administrative expenses in our Consolidated Statements of Operations and was $16.3 , $18.9 and $24.1 in 2015 , 2014 and 2013 , respectively. Factors that would cause this provision to increase primarily relate to increased bankruptcies by our clients and other difficulties collecting amounts billed. On the other hand, an improved write-off experience and aging of receivables would result in a decrease to the provision. Write-offs were $20.3 , $15.8 and $26.4 for 2015 , 2014 and 2013 , respectively. Advertising Costs We expense production costs of advertising as they are incurred. Advertising expenses were $28.8 , $25.7 and $22.3 in 2015 , 2014 and 2013 , respectively. Restructuring Costs We recorded net restructuring costs of $16.4 and $89.4 in 2015 and 2013, respectively, in selling and administrative expenses, primarily related to severances and office closures and consolidations in multiple countries and territories. During 2015 and 2014 , we made payments of $12.9 and $35.5 , respectively, out of our restructuring reserve. We expect a majority of the remaining $16.4 reserve will be paid by the end of 2016 . Changes in the restructuring liability balances for each reportable segment and Corporate are as follows: Americas (1) Southern Europe (2) Northern Europe APME Right Management Corporate Total Balance, January 1, 2014 $ 6.8 $ 4.5 $ 22.2 $ 1.8 $ 12.3 $ 0.8 $ 48.4 Costs paid or utilized (5.7 ) (2.2 ) (16.4 ) (1.3 ) (10.0 ) 0.1 (35.5 ) Balance, December 31, 2014 1.1 2.3 5.8 0.5 2.3 0.9 12.9 Severance costs 2.5 — 8.6 0.9 1.1 — 13.1 Office closure costs 0.7 — 0.4 2.0 0.2 — 3.3 Costs paid or utilized (0.8 ) (0.6 ) (6.3 ) (1.7 ) (2.8 ) (0.7 ) (12.9 ) Balance, December 31, 2015 $ 3.5 $ 1.7 $ 8.5 $ 1.7 $ 0.8 $ 0.2 $ 16.4 (1) Balance related to United States was $5.1 as of January 1, 2014. In 2014 , United States paid/utilized $4.1 , leaving a $1.0 liability as of December 31, 2014 . In 2015 , United States incurred $2.3 for severance costs and $0.7 for office closure costs and paid/utilized $1.1 , leaving a $2.9 liability as of December 31, 2015 . (2) Balance related to France was $3.5 as of January 1, 2014. In 2014 , France paid/utilized $1.4 , leaving a $2.1 liability as of December 31, 2014 . In 2015 , France paid/utilized $0.6 , leaving a $1.5 liability as of December 31, 2015 . Italy had a $0.9 liability as of January 1, 2014. In 2014 , Italy paid/utilized $0.9 , leaving no liability as of December 31, 2014 or 2015 . Income Taxes We account for income taxes in accordance with the accounting guidance on income taxes. Deferred tax assets and liabilities are recognized for the future tax consequences attributable to differences between financial statement carrying amounts of existing assets and liabilities and their respective tax basis, and net operating loss and tax credit carryforwards. Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled. We record a valuation allowance against deferred tax assets to reduce the assets to the amounts more likely than not to be realized. Fair Value Measurements The assets and liabilities measured and recorded at fair value on a recurring basis were as follows: Fair Value Measurements Using Fair Value Measurements Using December 31, 2015 Quoted Prices in Active Markets for Identical Assets (Level 1) Significant Other Observable Inputs (Level 2) Significant Unobservable Inputs (Level 3) December 31, 2014 Quoted Prices in Active Markets for Identical Assets (Level 1) Significant Other Observable Inputs (Level 2) Significant Unobservable Inputs (Level 3) Assets Foreign currency forward contracts $ 0.1 $ — $ 0.1 $ — $ 0.1 $ — $ 0.1 $ — Deferred compensation plan assets 84.1 84.1 — — 81.4 81.4 — — $ 84.2 $ 84.1 $ 0.1 $ — $ 81.5 $ 81.4 $ 0.1 $ — Liabilities Foreign currency forward contracts $ 0.5 $ — $ 0.5 $ — $ — $ — $ — $ — $ 0.5 $ — $ 0.5 $ — $ — $ — $ — $ — 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 third parties. The carrying values of cash and cash equivalents, accounts receivable, accounts payable, and other current assets and liabilities approximate their fair values because of the short-term nature of these instruments. The carrying value of our variable-rate long-term debt approximates fair value. The fair value of the euro-denominated notes, as observable at commonly quoted intervals (Level 2 inputs), was $858.2 and $471.6 as of December 31, 2015 and 2014 , respectively, compared to a carrying value of $810.2 and $422.1 , respectively. Goodwill and Other Intangible Assets We have goodwill, finite-lived intangible assets and indefinite-lived intangible assets as follows: 2015 2014 December 31 Gross Accumulated Amortization Net Gross Accumulated Amortization Net Goodwill (1) $ 1,257.4 $ — $ 1,257.4 $ 1,075.2 $ — $ 1,075.2 Intangible assets: Finite-lived: Technology $ — $ — $ — $ 19.6 $ 19.6 $ — Franchise agreements — — — 18.0 18.0 — Customer relationships 425.6 256.7 168.9 359.9 225.6 134.3 Other 16.9 9.9 7.0 14.2 13.0 1.2 442.5 266.6 175.9 411.7 276.2 135.5 Indefinite-lived: Tradenames (2) 54.0 — 54.0 54.0 — 54.0 Reacquired franchise rights 96.6 — 96.6 97.3 — 97.3 150.6 — 150.6 151.3 — 151.3 Total intangible assets $ 593.1 $ 266.6 $ 326.5 $ 563.0 $ 276.2 $ 286.8 (1) Balances were net of accumulated impairment loss of $513.4 as of both December 31, 2015 and 2014 . (2) Balances were net of accumulated impairment loss of $139.5 as of both December 31, 2015 and 2014 . Amortization expense related to intangibles was $32.8 , $33.4 and $34.1 in 2015 , 2014 and 2013 , respectively. Amortization expense expected in each of the next five years related to acquisitions completed as of December 31, 2015 is as follows: 2016 - $34.8 , 2017 - $31.8 , 2018 - $29.0 , 2019 - $24.7 and 2020 - $20.2 . The weighted-average useful lives of the customer relationships and other are 13 and 4 years, respectively. The tradenames have been assigned an indefinite life based on our expectation of renewing the tradenames, as required, without material modifications and at a minimal cost, and our expectation of positive cash flows beyond the foreseeable future. The reacquired franchise rights result from our franchise acquisitions in the United States and Canada completed prior to 2009. In accordance with the accounting guidance on goodwill and other intangible assets, we perform an annual impairment test of goodwill at our reporting unit level and indefinite-lived intangible assets at our unit of account level during the third quarter, or more frequently if events or circumstances change that would more likely than not reduce the fair value of our reporting units below their carrying value. We performed our annual impairment test of our goodwill and indefinite-lived intangible assets during the third quarter of 2015 , 2014 and 2013 , and there was no impairment of our goodwill or indefinite-lived intangible as a result of our annual tests. We utilize a two-step method for determining goodwill impairment. In the first step, we determined the fair value of each reporting unit, generally by utilizing an income approach derived from a discounted cash flow methodology. For certain of our reporting units, a combination of the income approach (weighted 75% ) and the market approach (weighted 25% ) derived from comparable public companies was utilized. The income approach is developed from management’s forecasted cash flow data. Therefore, it represents an indication of fair market value reflecting management’s internal outlook for the reporting unit. The market approach utilizes the Guideline Public Company Method to quantify the respective reporting unit’s fair value based on revenues and earnings multiples realized by similar public companies. The market approach is more volatile as an indicator of fair value as compared to the income approach. We believe that each approach has its merits. However, in the instances where we have utilized both approaches, we have weighted the income approach more heavily than the market approach because we believe that management’s assumptions generally provide greater insight into the reporting unit’s fair value. Significant assumptions used in our goodwill impairment tests during 2015 , 2014 and 2013 included: expected revenue growth rates, operating unit profit margins, working capital levels, discount rates ranging from 11.8% to 17.1% for 2015 , and a terminal value multiple. The expected future revenue growth rates and the expected operating unit profit margins were determined after considering our historical revenue growth rates and operating unit profit margins, our assessment of future market potential, and our expectations of future business performance. If the reporting unit’s fair value is less than its carrying value, we are required to perform a second step. In the second step, we allocate the fair value of the reporting unit to all of the assets and liabilities of the reporting unit, including any unrecognized intangible assets, in a “hypothetical” calculation to determine the implied fair value of the goodwill. The impairment charge, if any, is measured as the difference between the implied fair value of the goodwill and its carrying value. Under the current accounting guidance, we are also required to test our indefinite-lived intangible assets for impairment by comparing the fair value of the intangible asset with its carrying value. If the intangible asset’s fair value is less than its carrying value, an impairment loss is recognized for the difference. Marketable Securities We account for our marketable security investments in accordance with the accounting guidance on investments in debt and equity securities, and have historically determined that all such investments are classified as available-for-sale. Accordingly, unrealized gains and unrealized losses that are determined to be temporary, net of related income taxes, are included in accumulated other comprehensive loss, which is a separate component of shareholders’ equity. Realized gains and losses, and unrealized losses determined to be other-than-temporary, are recorded in our Consolidated Statements of Operations. We hold a 49% interest in our Swiss franchise, accounted for under the equity method of accounting, which maintained an investment portfolio with a market value of $202.3 and $200.9 as of December 31, 2015 and 2014 , respectively. This portfolio is comprised of a wide variety of European and United States debt and equity securities as well as various professionally-managed funds, all of which are classified as available-for-sale. Our share of net realized gains and losses, and declines in value determined to be other-than-temporary, are included in our Consolidated Statements of Operations. For the years ended December 31, 2015 , 2014 and 2013 , realized gains totaled $2.3 , $2.5 and $3.6 , respectively, and realized losses totaled $1.1 , $0.5 and $1.4 , respectively. Other-than-temporary impairment amounts for 2015 and 2013 were net gains of $0.2 and $0.9 , respectively, as previously impaired investments were sold for a gain, and 2014 was a loss of $0.1 . Our share of net unrealized gains and unrealized losses that are determined to be temporary related to these investments are included in accumulated other comprehensive loss, with the offsetting amount increasing or decreasing our investment in the franchise. Capitalized Software for Internal Use We capitalize purchased software as well as internally developed software. Internal software development costs are capitalized from the time the internal use software is considered probable of completion until the software is ready for use. Business analysis, system evaluation, selection and software maintenance costs are expensed as incurred. Capitalized software costs are amortized using the straight-line method over the estimated useful life of the software which ranges from 3 to 10 years. The net capitalized software balance of $5.1 and $5.3 as of December 31, 2015 and 2014 , respectively, is included in other assets in the Consolidated Balance Sheets. Amortization expense related to the capitalized software costs was $1.7 , $2.2 and $5.6 for 2015 , 2014 and 2013 , respectively. Property and Equipment A summary of property and equipment as of December 31 is as follows: 2015 2014 Land $ 5.4 $ 5.7 Buildings 16.7 19.2 Furniture, fixtures, and autos 166.6 178.2 Computer equipment 133.2 153.0 Leasehold improvements 263.5 277.4 Property and equipment $ 585.4 $ 633.5 Property and equipment are stated at cost and are depreciated using primarily the straight-line method over the following estimated useful lives: buildings - up to 40 years; furniture, fixtures, autos and computer equipment - 2 to 16 years; leasehold improvements - lesser of life of asset or expected lease term. Expenditures for renewals and betterments are capitalized whereas expenditures for repairs and maintenance are charged to income as incurred. Upon sale or disposition of property and equipment, the difference between the unamortized cost and the proceeds is recorded as either a gain or a loss and is included in our Consolidated Statements of Operations. Long-lived assets are evaluated for impairment in accordance with the provisions of the accounting guidance on the impairment or disposal of long-lived assets. Derivative Financial Instruments We account for our derivative instruments in accordance with the accounting guidance on derivative instruments and hedging activities. Derivative instruments are recorded on the balance sheet as either an asset or liability measured at their fair value. If the derivative is designated as a fair value hedge, the changes in the fair value of the derivative and of the hedged item attributable to the hedged risk are recognized in earnings. If the derivative is designated as a cash flow hedge, the effective portions of the changes in the fair value of the derivative are recorded as a component of accumulated other comprehensive loss and recognized in the Consolidated Statements of Operations when the hedged item affects earnings. The ineffective portions of the changes in the fair value of cash flow hedges are recognized in earnings. Foreign Currency Translation The financial statements of our non-United States subsidiaries have been translated in accordance with the accounting guidance on foreign currency translation. Under the accounting guidance, asset and liability accounts are translated at the current exchange rates and income statement items are translated at the average exchange rates each month. The resulting translation adjustments are recorded as a component of accumulated other comprehensive loss, which is included in shareholders’ equity. A portion of our euro-denominated notes are accounted for as a hedge of our net investment in our subsidiaries with a euro-functional currency. Since our net investment in these subsidiaries exceeds the amount of the related borrowings, net of tax, all translation gains or losses related to these borrowings are included as a component of accumulated other comprehensive loss. Shareholders’ Equity In October 2015 and December 2012, the Board of Directors authorized the repurchase of 6.0 million and 8.0 million shares of our common stock, respectively. 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. In 2015, we repurchased a total of 6.7 million shares, comprised of 6.0 million shares under the 2012 authorization and 0.7 million shares under the 2015 authorization, at a total cost of $587.9 , including a nominal amount of shares at a cost of $7.7 that settled in January 2016. The share repurchases that settled in January are not reflected in the treasury stock in our Consolidated Balance Sheets as of December 31, 2015 . In 2014, we repurchased 2.0 million shares under the 2012 authorization at a cost of $143.5 . No repurchases were made in 2013 . As of December 31, 2015 , there were 5.3 million shares remaining authorized for repurchase under the 2015 authorization and no shares remaining under the 2012 authorization. During 2015 , 2014 and 2013 , the Board of Directors declared total cash dividends of $1.60 , $0.98 and $0.92 per share, respectively, resulting in total dividend payments of $121.0 , $77.3 and $72.0 , respectively. During the third quarter of 2015, we entered into a joint venture to expand our business in the Greater China region. We contributed a majority of the net assets of our China, Hong Kong, Macau and Taiwan operations and the noncontrolling shareholder contributed cash. The joint venture is included in our Consolidated Balance Sheets as of December 31, 2015 as we have a controlling financial interest. The noncontrolling equity interest is included in noncontrolling interests in total shareholders’ equity in our Consolidated Balance Sheets as of December 31, 2015. Noncontrolling interests also includes amounts related to other majority-owned subsidiaries for which we have a controlling financial interest. Net earnings, net of tax, attributable to these noncontrolling interests were $6.6 for the year ended December 31, 2015. Cash and Cash Equivalents We consider all highly liquid investments with an original maturity of three months or less when purchased to be cash equivalents. Payroll Tax Credit In January 2013, the French government passed legislation, Credit d’Impôt pour la Compétitivité et l’Emploi (“CICE”), effective January 1, 2013, that provides payroll tax credits based on a percentage of wages paid to employees receiving less than two-and-a-half times the French minimum wage. The payroll tax credit was equal to 4% of eligible wages in 2013 and 6% of eligible wages in 2014 and beyond. The CICE payroll tax credit is accounted for as a reduction of our cost of services in the period earned. The payroll tax credit is creditable against our current French income tax payable, with any remaining amount being paid after three years. Given the amount of our current income taxes payable, we would generally receive the vast majority of these payroll tax credits after the three-year period. In July 2015 and December 2013, we entered into an agreement to sell a portion of the credits earned in 2014 and 2013, respectively, for net proceeds of $132.8 ( €120.1 ) and $104.0 ( €75.8 ), respectively. We derecognized these receivables upon the sale 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 as a reduction of the payroll tax credits earned in the respective years in cost of services. Recently Issued Accounting Standards In May 2014, the FASB issued new accounting guidance on revenue from contracts with customers. The core principle of this amendment is that an entity should recognize revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. The original guidance was effective for us in 2017; however in August 2015, the FASB issued guidance that deferred the effective date by one year for all entities. The new guidance is effective for us in 2018 and can be adopted either retrospectively to each prior reporting period presented or as a cumulative-effect adjustment as of the date of adoption, with early adoption permitted, but not before the original effective date. We are currently assessing the impact of the adoption of this guidance on our Consolidated Financial Statements. In April 2015, the FASB issued new accounting guidance on debt issuance costs. The new guidance requires debt issuance costs related to a recognized debt liability to be presented in the balance sheet as a direct deduction from the associated liability, consistent with debt discounts. As of September 2015, we adopted this guidance and reclassified debt issuance costs associated with our long-term debt from other assets to long-term debt in prior-period financial statements to conform to the current period's presentation. The impact of the adoption of this guidance is disclosed in Note 7 to the Consolidated Financial Statements. In September 2015, the FASB issued new accounting guidance on business combinations. The new guidance eliminates the requirement to restate prior period financial statements for measurement period adjustments following a business combination. It requires that the cumulative impact of a measurement period adjustment (including the impact on prior periods) be recognized in the reporting period in which the adjustment is identified. The prior period impact of the adjustment should be either presented separately on the face of the income statement or disclosed in the notes. The guidance is effective for us in 2016. We do not expect the adoption of this guidance to have a material impact on our Consolidated Financial Statements. In November 2015, the FASB issued new accounting guidance on the balance sheet classification of deferred taxes. The new guidance requires that all deferred taxes be presented as noncurrent. In the fourth quarter of 2015, we adopted this guidance and reclassified current deferred tax assets and current deferred tax liabilities from future income tax benefits and accrued liabilities, respectively, to other assets and other long-term liabilities, respectively, in prior-period financial statements to conform to the current period's presentation. The impact of the adoption of this guidance is disclosed in Note 5 to the Consolidated Financial Statements. In January 2016, the FASB issued new accounting guidance on financial instruments. The new guidance changes the accounting for equity investments, financial liability under the fair value option and the presentation and disclosure requirements for financial instruments. The guidance is effective for us in 2018. We do not expect the adoption of this guidance to have a material impact on our Consolidated Financial Statements. Reclassification In connection with the adoption in the third quarter of 2015 of the new accounting guidance on debt issuance costs, we have reclassified certain amounts in prior-period financial statements to conform to the current period's presentation. In our Consolidated Balance Sheets, we have reclassified debt issuance costs associated with our long-term debt from other assets to long-term debt (see Note 7 to the Consolidated Financial Statements). In connection with the adoption in the fourth quarter of 2015 of the new accounting guidance on balance sheet classification of deferred taxes, we have reclassified certain amounts in prior-period financial statements to conform to the current period's presentation. In our Consolidated Balance Sheets, we have reclassified current deferred tax assets and current deferred tax liabilities from future income tax (expense) benefits and accrued liabilities, respectively, to other assets and other long-term liabilities, respectively (see Note 5 to the Consolidated Financial Statements). Subsequent Events We have evaluated events and transactions occurring after the balance sheet date through our filing date and noted no events that are subject to recognition or disclosure.

Acquisitions

Business Combinations [Abstract]
Acquisitions	Acquisitions On September 3, 2015, we acquired 7S Group GmbH (“7S”), for total consideration, net of cash acquired, of $140.4 ( €125.3 ). In addition, we incurred approximately $3.4 of transaction costs associated with the acquisition during the year ended December 31, 2015, which have been recorded in selling and administrative expenses. Based primarily in Germany, 7S is a highly specialized provider of human resource services focusing on a number of core sectors including skilled trades, engineering and IT. Of the $153.0 ( €136.5 ) of net acquired assets, $48.8 ( €43.5 ) was recorded as finite-lived intangible assets, of which $44.2 ( €39.4 ) was assigned to customer relationships and will be amortized over 10 years using the straight line method. As of December 31, 2015, the customer relationships were $41.4 ( €38.1 ). Total amortization expense related to this intangible asset in each of the next five years is $4.3 . The fair value of $119.3 ( €106.4 ), which was not directly attributable to any specific assets or liabilities, was assigned to goodwill as part of the Germany reporting unit. As of December 31, 2015, the purchase accounting and figures associated with the above acquisition were preliminary and will be finalized in early 2016. From time to time, we acquire and invest in companies throughout the world, including franchises. The total cash consideration for acquisitions excluding 7S, net of cash acquired, was $120.1 for the year ended December 31, 2015 , the majority of which took place in Australia, Canada and the Netherlands. The total cash consideration for acquisitions, net of cash acquired, for the years ended 2014 and 2013 was $32.0 and $46.3 , respectively. Goodwill and intangible assets resulting from the remaining 2015 acquisitions were $108.7 and $28.5 , respectively, as of December 31, 2015 . Goodwill and intangible assets resulting from the 2014 acquisitions, the majority of which took place in the Netherlands and the United Kingdom, were $39.4 and $10.1 , respectively, as of December 31, 2014 .

Disclosure of Compensation Related Costs, Share-based Payments [Abstract]
Share-Based Compensation Plans	Share-Based Compensation Plans We account for share-based payments according to the accounting guidance on share-based payments. During 2015 , 2014 and 2013 , we recognized $31.1 , $40.6 and $31.5 , respectively, in share-based compensation expense related to stock options, deferred stock, restricted stock and performance share units, all of which is recorded in selling and administrative expenses. The total income tax benefit recognized related to share-based compensation during 2015 , 2014 and 2013 was $16.9 , $12.2 and $21.2 , respectively. Consideration received from share-based awards for 2015 , 2014 and 2013 was $70.1 , $25.5 and $101.0 , respectively. The excess income tax benefit recognized related to share-based compensation awards, which is recorded in capital in excess of par value, for 2015 , 2014 and 2013 was approximately $7.4 , $4.6 and $8.4 , respectively. We recognize compensation expense on grants of share-based compensation awards on a straight-line basis over the vesting period of each award. Stock Options All share-based compensation is granted under the 2011 Equity Incentive Plan of Manpower Inc. (“2011 Plan”). Options and stock appreciation rights are granted at a price not less than 100% of the fair market value of the common stock at the date of grant. Generally, options are granted with a ratable vesting period of up to four years and expire ten years from date of grant. No stock appreciation rights had been granted or were outstanding as of December 31, 2015 or 2014 . A summary of stock option activity is as follows: Shares (000) Wtd. Avg. Exercise Price Per Share Wtd. Avg. Remaining Contractual Term (years) Aggregate Intrinsic Value (in millions) Outstanding, January 1, 2013 5,344 $ 50 Granted 221 53 Exercised (2,576 ) 43 $ 63 Expired or cancelled (206 ) 51 Outstanding, December 31, 2013 2,783 $ 57 5.1 $ 81 Vested or expected to vest, December 31, 2013 2,769 $ 57 4.8 Exercisable, December 31, 2013 2,153 $ 58 4.2 $ 60 Outstanding, January 1, 2014 2,783 $ 57 Granted 204 77 Exercised (473 ) 53 $ 13 Expired or cancelled (30 ) 43 Outstanding, December 31, 2014 2,484 $ 59 4.7 $ 28 Vested or expected to vest, December 31, 2014 2,476 $ 59 4.5 Exercisable, December 31, 2014 1,957 $ 59 3.7 $ 23 Outstanding, January 1, 2015 2,484 $ 59 Granted 147 77 Exercised (1,255 ) 56 $ 39 Expired or cancelled (104 ) 56 Outstanding, December 31, 2015 1,272 $ 64 5.2 $ 26 Vested or expected to vest, December 31, 2015 1,267 $ 64 5.2 Exercisable, December 31, 2015 911 $ 62 4.0 $ 20 Options outstanding and exercisable as of December 31, 2015 are as follows: Options Outstanding Options Exercisable Exercise Price Shares (000) Weighted- Average Remaining Contractual Life (years) Weighted- Average Exercise Price Shares (000) Weighted-Average Exercise Price $27-$34 44 2.9 $ 30 44 $ 30 $35-$44 86 6.1 45 54 45 $45-$55 347 5.1 53 273 53 $56-$93 795 5.2 73 540 71 1,272 5.2 $ 64 911 $ 62 We have recognized expense of $3.2 , $6.8 and $7.5 related to stock options for the years ended December 31, 2015 , 2014 and 2013 , respectively. The total fair value of options vested during the same periods was $3.2 , $11.1 and $9.0 , respectively. As of December 31, 2015 , total unrecognized compensation cost was approximately $2.1 , net of estimated forfeitures, which we expect to recognize over a weighted-average period of approximately 1.3 years. We estimated the fair value of each stock option on the date of grant using the Black-Scholes option pricing model and the following assumptions: Year Ended December 31 2015 2014 2013 Average risk-free interest rate 1.6 % 1.8 % 1.1 % Expected dividend yield 1.5 % 1.2 % 1.7 % Expected volatility 32.0 % 37.0 % 42.0 % Expected term (years) 6.0 5.9 5.9 The average risk-free interest rate is based on the five -year United States Treasury security rate in effect as of the grant date. The expected dividend yield is based on the expected annual dividend as a percentage of the market value of our common stock as of the grant date. We determined expected volatility using a weighted average of daily historical volatility (weighted 75% ) of our stock price over the past five years and implied volatility (weighted 25% ) based upon exchange traded options for our common stock. We believe that a blend of historical volatility and implied volatility better reflects future market conditions and better indicates expected volatility than considering purely historical volatility. We determined the expected term of the stock options using historical data. The weighted-average grant-date fair value per option granted during the year was $21.66 , $25.64 and $17.99 in 2015 , 2014 and 2013 , respectively. Deferred Stock Our non-employee directors may elect to receive deferred stock in lieu of part or all of their annual cash retainer otherwise payable to them. The number of shares of deferred stock is determined pursuant to a formula set forth in the terms and conditions adopted under the 2011 Plan; the deferred stock is settled in shares of common stock according to these terms and conditions. As of December 31, 2015 , 2014 and 2013 , there were 36,091 , 33,985 and 31,733 , respectively, shares of deferred stock awarded under this arrangement, all of which are vested. Non-employee directors also receive an annual grant of deferred stock (or restricted stock, if they so elect) as additional compensation for board service. The award vests in equal quarterly installments over one year and the vested portion of the deferred stock is settled in shares of common stock either upon a director’s termination of service or three years after the date of grant (which may in most cases be extended at the directors’ election) in accordance with the terms and conditions under the 2011 Plan. As of December 31, 2015 , 2014 and 2013 , there were 7,920 , 5,199 and 14,844 , respectively, shares of deferred stock and 13,860 , 10,248 and 14,844 , respectively, shares of restricted stock granted under this arrangement, all of which are vested, except for 1,752 shares of restricted stock granted in 2015 that were cancelled. We recognized expense of $0.8 , $0.7 and $0.9 related to deferred stock in 2015 , 2014 and 2013 , respectively. Restricted Stock We grant restricted stock and restricted stock unit awards to certain employees and to non-employee directors who may elect to receive restricted stock rather than deferred stock as described above. Restrictions lapse over periods ranging up to six years, and in some cases upon retirement. We value restricted stock awards at the closing market value of our common stock on the date of grant. A summary of restricted stock activity is as follows: Shares (000) Wtd. Avg. Price Per Share Wtd. Avg. Remaining Contractual Term (years) Aggregate Intrinsic Value (in millions) Unvested, January 1, 2013 589 $ 55 1.7 Granted 192 52 Vested (90 ) 52 Forfeited (64 ) 56 Unvested, December 31, 2013 627 $ 54 1.3 Granted 169 $ 77 Vested (283 ) 63 Forfeited (50 ) 53 Unvested, December 31, 2014 463 $ 57 1.2 Granted 179 $ 76 Vested (217 ) 59 Forfeited (20 ) 60 Unvested, December 31, 2015 405 $ 64 1.3 $ 34 During 2015 , 2014 and 2013 , we recognized $9.9 , $12.9 and $9.8 , respectively, of expense related to restricted stock awards. As of December 31, 2015 , there was approximately $11.6 of total unrecognized compensation cost related to unvested restricted stock, which we expect to recognize over a weighted-average period of approximately 1.8 years. Performance Share Units Our 2011 Plan allows us to grant performance share units. We grant performance share units with a performance period ranging from one to three years. Vesting of units occurs at the end of the performance period or after a subsequent holding period, except in the case of termination of employment where the units are forfeited immediately. Upon retirement, a prorated number of units vest depending on the period worked from the grant date to retirement date or in certain cases all of the units vest. In the case of death or disability, the units immediately vest at the Target Award level if the death or disability date is during the performance period, or at the level determined by the performance criteria met during the performance period if the death or disability occurs during the subsequent holding period. The units are settled in shares of our common stock. A payout multiple is applied to the units awarded based on the performance criteria determined by the Executive Compensation and Human Resources Committee of the Board of Directors at the time of grant. In the event the performance criteria exceeds the Target Award level, an additional number of shares, up to the Outstanding Award level, may be granted. In the event the performance criteria falls below the Target Award level, a reduced number of shares, as low as the Threshold Award level, may be granted. If the performance criteria falls below the Threshold Award level, no shares will be granted. A summary of the performance share units detail by grant year is as follows: 2013 (a) 2014 (b) 2015 Grant Date(s) February 14, February 11, February 11, 2015 Performance Period (years) 2013 2014-2016 2015-2017 Vesting Date(s) 50% on 100% in (c) 100% in February, 2018 (c) Payout Levels (in units): Threshold Award 76,120 94,608 82,298 Target Award 152,240 189,215 164,595 Outstanding Award 304,480 378,430 329,190 Shares Issued in 2015 54,617 — — Shares Subject to Holding Period as of December 31, 2015 46,623 — — (a) The award achieved 140% of the Target Award level over the performance period. Included in these figures is another award consisting of 7,610 of performance share units that were granted on February 14, 2013 with a separate performance period, performance criteria and vesting date. The performance period was 2013 through 2015 , with a vesting date of July 1, 2016. The award achieved 124% of the Target Award level over the performance period. (b) Included in these figures are 3,046 of performance share units that were granted on October 29, 2014 with a separate performance period, performance criteria and vesting date. The performance period is June 1, 2015 through December 31, 2016, with a vesting date of October 29, 2017. (c) 2014 and 2015 awards are scheduled to vest in February 2017 and 2018, respectively, when the Board of Directors certify the Award levels that are achieved. We recognize and adjust compensation expense based on the likelihood of the performance criteria specified in the award being achieved. The compensation expense is recognized over the performance and holding periods and is recorded in selling and administrative expenses. We have recognized total compensation expense of $17.1 , $20.1 and $13.1 in 2015 , 2014 and 2013 , respectively, related to the performance share units. Other Stock Plans Under the 1990 Employee Stock Purchase Plan, designated employees meeting certain service requirements may purchase shares of our common stock through payroll deductions. These shares may be purchased at their fair market value on a monthly basis. The current plan is non-compensatory according to the accounting guidance on share-based payments. We also maintain the Savings Related Share Option Scheme for United Kingdom employees with at least one year of service. The employees are offered the opportunity to obtain an option for a specified number of shares of common stock at not less than 85% of its market value on the day prior to the offer to participate in the plan. Options vest after either three , five or seven years, but may lapse earlier. Funds used to purchase the shares are accumulated through specified payroll deductions over a 60 -month period. We recognized an expense of $0.1 , $0.1 and $0.2 for shares purchased under the plan in 2015 , 2014 and 2013 , respectively.

Income Taxes	Income Taxes The provision for income taxes was as follows: Year Ended December 31 2015 2014 2013 Current United States Federal $ (8.4 ) $ 44.8 $ (0.8 ) State — 7.0 3.4 Non-United States 158.7 148.2 167.9 Total current 150.3 200.0 170.5 Deferred United States Federal 92.9 53.2 21.0 State 1.8 (1.9 ) 0.9 Non-United States (3.5 ) 2.7 (4.9 ) Total deferred 91.2 54.0 17.0 Total provision $ 241.5 $ 254.0 $ 187.5 A reconciliation between taxes computed at the United States Federal statutory rate of 35% and the consolidated effective tax rate is as follows: Year Ended December 31 2015 2014 2013 Income tax based on statutory rate $ 231.2 $ 238.6 $ 166.4 Increase (decrease) resulting from: Non-United States tax rate difference 20.4 20.1 27.7 Repatriation of non-United States earnings (16.9 ) (10.1 ) (20.5 ) State income taxes, net of Federal benefit 2.7 2.9 3.2 Change in valuation allowance 3.3 5.0 (0.5 ) Other, net 0.8 (2.5 ) 11.2 Tax provision $ 241.5 $ 254.0 $ 187.5 Included in non-United States tax rate difference are benefits of $1.5 and $2.8 for 2015 and 2014 , respectively, related to the French CICE payroll tax credit because the CICE credit is tax-free for French tax purposes. The tax benefits related to the CICE credit in excess of these amounts are offset by related increases in United States tax expense. For United States tax purposes, certain French earnings impacted by the CICE credit are treated as a deemed dividend in the current year or future years, resulting in an increase in United States tax expense. Deferred income taxes are recorded on temporary differences at the tax rate expected to be in effect when the temporary differences reverse. Temporary differences, which gave rise to the deferred taxes, were as follows: December 31 2015 2014 Future Income Tax (Expense) Benefits Accrued payroll taxes and insurance $ 31.5 $ 32.8 Employee compensation payable 31.7 28.1 Pension and postretirement benefits 57.5 60.5 Intangible assets (144.7 ) (124.7 ) Repatriation of non-United States earnings (132.0 ) (53.1 ) Intercompany loans denominated in foreign currencies (61.2 ) (25.6 ) Net operating losses 106.5 129.7 Other 133.1 119.7 Valuation allowance (95.9 ) (107.9 ) Total future tax (expense) benefits $ (73.5 ) $ 59.5 Deferred tax asset 83.9 106.2 Deferred tax liability (157.4 ) (46.7 ) Total future tax (expense) benefits $ (73.5 ) $ 59.5 In November 2015, the FASB issued new accounting guidance on the balance sheet classification of deferred taxes. The new guidance requires that all deferred taxes be presented as noncurrent. In the fourth quarter of 2015, we adopted this guidance and reclassified current deferred tax assets and current deferred tax liabilities from future income tax (expense) benefits and accrued liabilities, respectively, to other assets and other long-term liabilities, respectively, in prior-period financial statements to conform to the current period's presentation. The impact of this reclassification on the 2014 balances was a reclass of $52.2 from future income tax (expense) benefits to other assets and $20.6 from accrued liabilities to other long-term liabilities. We had United States Federal and non-United States net operating loss carryforwards and United States state net operating loss carryforwards totaling $378.5 and $256.8 , respectively, as of December 31, 2015 . The net operating loss carryforwards expire as follows: United States Federal and Non-United States United States State 2016 $ 3.6 $ 1.0 2017 3.4 7.5 2018 3.1 3.5 2019 7.9 4.5 2020 4.3 — Thereafter 27.4 240.3 No expirations 328.8 — Total net operating loss carryforwards $ 378.5 $ 256.8 We have recorded a deferred tax asset of $106.5 as of December 31, 2015 , for the benefit of these net operating losses. Realization of this asset is dependent on generating sufficient taxable income prior to the expiration of the loss carryforwards. A related valuation allowance of $91.1 has been recorded as of December 31, 2015 , as management believes that realization of certain net operating loss carryforwards is unlikely. Pre-tax earnings of non-United States operations was $511.2 , $485.9 and $298.1 in 2015 , 2014 and 2013 , respectively. We have not provided United States income taxes or non-United States withholding taxes on $516.9 of unremitted earnings of non-United States subsidiaries that are considered to be permanently invested. As of December 31, 2015 , deferred taxes are provided on $604.4 of unremitted earnings of non-United States subsidiaries that may be remitted to the United States. As of December 31, 2015 and 2014 , we have recorded a deferred tax liability of $132.0 and $53.1 , respectively, related to these non-United States earnings that may be remitted. As of December 31, 2015 , we had gross unrecognized tax benefits related to various tax jurisdictions, including interest and penalties, of $38.9 . We have related tax benefits of $1.0 , and the net amount of $37.9 would favorably affect the effective tax rate if recognized. We do not expect our unrecognized tax benefits to change significantly over the next year. As of December 31, 2014 , we had gross unrecognized tax benefits related to various tax jurisdictions, including interest and penalties, of $30.8 . We had related tax benefits of $1.4 for a net amount of $29.4 . We recognize accrued interest and penalties related to unrecognized tax benefits in income tax expense. During 2015 , we accrued net interest and penalties of $12.1 . We recorded a benefit of $0.6 in 2014 and accrued net interest and penalties of $6.3 in 2013 . The following table summarizes the activity related to our unrecognized tax benefits during 2015 , 2014 and 2013 : 2015 2014 2013 Gross unrecognized tax benefits, beginning of year $ 23.0 $ 23.9 $ 26.4 Increases in prior year tax positions 2.3 0.7 2.1 Decreases in prior year tax positions (0.5 ) (1.2 ) (5.6 ) Increases for current year tax positions 3.1 2.2 3.4 Expiration of statute of limitations and audit settlements (8.9 ) (2.6 ) (2.4 ) Gross unrecognized tax benefits, end of year $ 19.0 $ 23.0 $ 23.9 Potential interest and penalties 19.9 7.8 8.4 Balance, end of year $ 38.9 $ 30.8 $ 32.3 We conduct business globally in 80 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 2008 through 2015 for our major operations in France, Germany, Italy, Japan, the United Kingdom and the United States. As of December 31, 2015 , we were subject to tax audits in Austria, Canada, Denmark, France, Germany, Italy, Portugal, Russia, Spain and the United States. We believe that the resolution of these audits will not have a material impact on earnings.

Debt Disclosure [Abstract]
Debt	Debt Information concerning short-term borrowings is as follows: December 31 2015 2014 Short-term borrowings $ 38.2 $ 43.3 Weighted-average interest rates 17.8 % 15.8 % We maintain separate bank credit lines with financial institutions to meet working capital needs of our subsidiary operations. As of December 31, 2015 , such uncommitted credit lines totaled $292.9 , of which $248.0 was unused. Under our revolving credit agreement, total subsidiary borrowings cannot exceed $300.0 in the first, second and fourth quarters, and $600.0 in the third quarter of each year. A summary of long-term debt is as follows: December 31 2015 2014 Euro-denominated notes: €400 due September 2022 $ 431.0 $ — €350 due June 2018 379.2 422.1 Other 6.7 2.4 816.9 424.5 Less — current maturities 6.0 1.9 Long-term debt $ 810.9 $ 422.6 Euro Notes On September 11, 2015, we offered and sold €400.0 aggregate principal amount of the Company's 1.875% notes due September 11, 2022 (the "€400.0 Notes"). The net proceeds from the €400.0 Notes of €397.4 will be used for general corporate purposes, which may include share repurchases and the acquisition of or investment in complementary businesses or other assets. The €400.0 Notes were issued at a price of 99.753% to yield an effective interest rate of 1.913% . Interest on the €400.0 Notes is payable in arrears on September 11 of each year. We also have €350.0 aggregate principal amount 4.50% notes due June 22, 2018 (the “€350.0 Notes”), which were issued at a price of 99.974% to yield an effective interest rate of 4.505% . Interest on the €350.0 Notes is payable in arrears on June 22 of each year. We may redeem the €350.0 Notes, in whole but not in part, at our option at any time for a redemption price determined in accordance with the term of the €350.0 Notes. When the €400.0 Notes and €350.0 Notes mature, we plan to repay the amounts with available cash, borrowings under our $600.0 revolving credit facility or a new borrowing. The credit terms, including interest rate and facility fees, of any replacement borrowings will be dependent upon the condition of the credit markets at that time. We currently do not anticipate any problems accessing the credit markets should we decide to replace either the €400.0 Notes or €350.0 Notes. Both the €400.0 Notes and €350.0 Notes contain certain customary non-financial restrictive covenants and events of default and are unsecured senior obligations and rank equally with all of our existing and future senior unsecured debt and other liabilities. A portion of the €400.0 Notes and €350.0 Notes were designated as a hedge of our net investment in subsidiaries with a euro-functional currency as of December 31, 2015. Since our net investment in these subsidiaries exceeds the respective amount of the designated borrowings, translation gains or losses related to these borrowings are included as a component of accumulated other comprehensive loss (See Note 12 to the Consolidated Financial Statements for further information). Revolving Credit Agreement On September 16, 2015, we amended and restated our Five Year Credit Agreement (the “Amended Agreement”) with a syndicate of commercial banks primarily to revise the termination date of the facility from October 15, 2018 to September 16, 2020. The remaining material terms and conditions of the Amended Agreement are substantially similar to the material terms and conditions of our Amended and Restated Five Year Credit Agreement dated October 15, 2013. The Amended Agreement allows for borrowing of $600.0 in various currencies, and up to $150.0 may be used for the issuance of stand-by letters of credit. We had no borrowings under this facility as of both December 31, 2015 and 2014 . Outstanding letters of credit issued under the Amended Agreement totaled $0.9 and $1.0 as of December 31, 2015 and 2014 , respectively. Additional borrowings of $599.1 and $599.0 were available to us under the facility as of December 31, 2015 and 2014 , respectively. Under the Amended Agreement, a credit ratings-based pricing grid determines the facility fee and the credit spread that we add to the applicable interbank borrowing rate on all borrowings. At our current credit rating, the annual facility fee is 12.5 basis points paid on the entire facility and the credit spread is 100.0 basis points on any borrowings. The Amended Agreement contains customary restrictive covenants pertaining to our management and operations, including limitations on the amount of subsidiary debt that we may incur and limitations on our ability to pledge assets, as well as financial covenants requiring, among other things, that we comply with a leverage ratio (net Debt-to-EBITDA) of not greater than 3.5 to 1 and a fixed charge coverage ratio of not less than 1.5 to 1. The Amended Agreement also contains customary events of default, including, among others, payment defaults, material inaccuracy of representations and warranties, covenant defaults, bankruptcy or involuntary proceedings, certain monetary and non-monetary judgments, change of control and customary ERISA defaults. Reclassification In April 2015, the FASB issued new accounting guidance on debt issuance costs. The new guidance requires debt issuance costs related to a recognized debt liability to be presented in the balance sheet as a direct deduction from the associated liability, consistent with debt discounts. It does not affect the recognition and measurement of debt issuance costs. We elected to early adopt this guidance in the third quarter of 2015 on a retrospective basis, which required the restatement of prior periods as we reclassified debt issuance costs associated with our long-term debt from other assets to long-term debt in our Consolidated Balance Sheets. The adoption was not material to the Consolidated Financial Statements. Our revolving credit agreement is not in scope of the new accounting guidance and, therefore, the related debt issuance costs will continue to be presented in other assets. Debt Maturities The maturities of long-term debt payable within each of the four years subsequent to December 31, 2016 are as follows: 2017 — $0.4 , 2018 — $379.3 , 2019 — $0.1 , 2020 — $0.1 .

Retirement and Deferred Compens

Retirement and Deferred Compensation Plans	12 Months Ended

Compensation and Retirement Disclosure [Abstract]
Retirement and Deferred Compensation Plans	Retirement and Deferred Compensation Plans For all of our United States defined benefit and retiree health care plans, we adopted the Society of Actuaries’ RP-2006 mortality table with MP-2015 projection scale in determining the plans’ benefit obligations as of December 31, 2015. For two of our United States defined benefit plans, we changed the amortization period for gains and losses as of December 31, 2015. We elected to use the average remaining life expectancy instead of the average remaining service period for recognizing the gain/loss amortization component of net periodic benefit cost, as almost all of the plans' participants are now inactive. The impact of this change was not material to the Consolidated Financial Statements. This change was accounted for prospectively as a change in accounting estimate. Beginning in 2016, we will change the method we use to estimate the service and interest cost components of net periodic benefit cost for all of our United States defined benefit plans. Historically, the service and interest cost components have been estimated utilizing a single weighted-average discount rate derived from the yield curve used to measure the benefit obligation at the beginning of the year. Beginning in 2016, we will utilize a full yield curve approach to estimate these components by applying specific spot rates along the yield curve used in the determination of the benefit obligation to the relevant projected cash flows. We will make this change to improve the correlation between projected benefit cash flows and the corresponding yield curve spot rates and to provide a more precise measurement of service and interest costs. This change will result in a decrease in the 2016 service costs and interest components with an equal offset to actuarial gains (losses) with no net impact on the total benefit obligation. This change is accounted for prospectively as a change in accounting estimate. Defined Benefit Plans We sponsor several qualified and nonqualified pension plans covering permanent employees. The reconciliation of the changes in the plans’ benefit obligations and the fair value of plan assets and the funded status of the plans are as follows: United States Plans Non-United States Plans Year Ended December 31 2015 2014 2015 2014 Change in Benefit Obligation Benefit obligation, beginning of year $ 56.6 $ 53.8 $ 385.4 $ 331.6 Service cost — — 7.2 8.3 Interest cost 2.1 2.4 10.6 13.4 Transfers — — 5.2 1.1 Actuarial (gain) loss (1.7 ) 4.5 (43.2 ) 77.5 Plan participant contributions — — 0.2 0.3 Benefits paid (3.9 ) (4.1 ) (8.1 ) (6.9 ) Currency exchange rate changes — — (31.2 ) (39.9 ) Benefit obligation, end of year $ 53.1 $ 56.6 $ 326.1 $ 385.4 United States Plans Non-United States Plans Year Ended December 31 2015 2014 2015 2014 Change in Plan Assets Fair value of plan assets, beginning of year $ 40.6 $ 39.1 $ 349.1 $ 305.8 Actual return on plan assets (1.8 ) 3.0 (8.3 ) 71.6 Plan participant contributions — — 0.2 0.3 Company contributions 2.3 2.6 8.5 11.8 Benefits paid (3.9 ) (4.1 ) (8.1 ) (6.9 ) Currency exchange rate changes — — (26.7 ) (33.5 ) Fair value of plan assets, end of year $ 37.2 $ 40.6 $ 314.7 $ 349.1 Funded Status at End of Year Funded status, end of year $ (15.9 ) $ (16.0 ) $ (11.4 ) $ (36.3 ) Amounts Recognized Noncurrent assets $ 14.3 $ 16.0 $ 47.9 $ 32.2 Current liabilities (2.4 ) (2.3 ) (0.3 ) (0.3 ) Noncurrent liabilities (27.8 ) (29.7 ) (59.0 ) (68.2 ) Net amount recognized $ (15.9 ) $ (16.0 ) $ (11.4 ) $ (36.3 ) Amounts recognized in accumulated other comprehensive loss, net of tax, consist of: United States Plans Non-United States Plans Year Ended December 31 2015 2014 2015 2014 Net loss $ 11.8 $ 11.3 $ 15.9 $ 36.0 Prior service cost — — 4.9 4.8 Total $ 11.8 $ 11.3 $ 20.8 $ 40.8 The accumulated benefit obligation for our plans that have plan assets was $291.9 and $340.7 as of December 31, 2015 and 2014 , respectively. The accumulated benefit obligation for certain of our plans exceeded the fair value of plan assets as follows: December 31 2015 2014 Accumulated benefit obligation $ 10.2 $ 10.8 Plan assets 9.6 9.6 The projected benefit obligation for certain of our plans exceeded the fair value of plan assets as follows: December 31 2015 2014 Projected benefit obligation $ 48.4 $ 52.1 Plan assets 39.4 42.0 By their nature, certain of our plans do not have plan assets. The accumulated benefit obligation for these plans was $69.9 and $76.1 as of December 31, 2015 and 2014 , respectively. The components of the net periodic benefit cost and other amounts recognized in other comprehensive loss for all plans were as follows: Year Ended December 31 2015 2014 2013 Net Periodic Benefit Cost Service cost $ 7.2 $ 8.3 $ 8.7 Interest cost 12.7 15.8 14.8 Expected return on assets (12.9 ) (15.6 ) (13.2 ) Curtailment and settlement — — (2.3 ) Net loss 4.0 3.5 3.3 Prior service cost 0.4 0.6 0.5 Net periodic benefit cost 11.4 12.6 11.8 Other Changes in Plan Assets and Benefit Obligation Recognized in Other Comprehensive (Income) Loss Net (gain) loss (22.9 ) 23.5 6.8 Prior service cost (credit) — 1.3 (1.1 ) Amortization of net loss (4.0 ) (3.5 ) (3.3 ) Amortization of prior service cost (0.4 ) (0.6 ) (0.5 ) Total recognized in other comprehensive (income) loss (27.3 ) 20.7 1.9 Total recognized in net periodic benefit cost and other comprehensive (income) loss $ (15.9 ) $ 33.3 $ 13.7 Effective January 1, 2013, we amended a defined benefit plan in the Netherlands. The defined benefit plan was frozen, and the participants were transitioned to a defined contribution plan, resulting in a curtailment gain of $ 2.3 . The estimated net loss and prior service cost for the defined benefit pension plans that will be amortized from accumulated other comprehensive loss into net periodic benefit cost during 2016 are $0.8 and $0.4 , respectively. The weighted-average assumptions used in the measurement of the benefit obligation were as follows: United States Plans Non-United States Plans Year Ended December 31 2015 2014 2015 2014 Discount rate 4.3 % 3.9 % 3.2 % 2.9 % Rate of compensation increase 3.0 % 3.0 % 2.2 % 3.4 % The weighted-average assumptions used in the measurement of the net periodic benefit cost were as follows: United States Plans Non-United States Plans Year Ended December 31 2015 2014 2013 2015 2014 2013 Discount rate 3.9 % 4.6 % 3.7 % 2.9 % 4.1 % 4.2 % Expected long-term return on plan assets 5.5 % 6.0 % 6.0 % 3.2 % 4.5 % 4.0 % Rate of compensation increase 3.0 % 3.0 % 3.0 % 2.6 % 3.8 % 3.6 % We determine our assumption for the discount rate based on an index of high-quality corporate bond yields and matched-funding yield curve analysis as of the end of each fiscal year. Our overall expected long-term rate of return used in the measurement of the 2015 net periodic benefit cost on United States plan assets was 5.5% , while the rates of return on our non-United States plans varied by country and ranged from 1.5% to 4.0% . For a majority of our plans, a building block approach has been employed to establish this return. Historical markets are studied and long-term historical relationships between equity securities and fixed income instruments are preserved consistent with the widely accepted capital market principle that assets with higher volatility generate a greater return over time. Current market factors such as inflation and interest rates are evaluated before long-term capital market assumptions are determined. The long-term portfolio return is established with proper consideration of diversification and rebalancing. We also use guaranteed insurance contracts for five of our foreign plans. Peer data and historical returns are reviewed to check for reasonableness and appropriateness of our expected rate of return. Projected salary levels utilized in the determination of the projected benefit obligation for the pension plans are based upon historical experience and the future expectations for each respective country. Our plans’ investment policies are to optimize the long-term return on plan assets at an acceptable level of risk and to maintain careful control of the risk level within each asset class. Our long-term objective is to minimize plan expenses and contributions by outperforming plan liabilities. We have historically used a balanced portfolio strategy based primarily on a target allocation of equity securities and fixed-income instruments, which vary by location. These target allocations, which are similar to the 2015 allocations, are determined based on the favorable risk tolerance characteristics of the plan and, at times, may be adjusted within a specified range to advance our overall objective. The fair values of our pension plan assets are primarily determined by using market quotes and other relevant information that is generated by market transactions involving identical or comparable assets, except for the insurance contract that is measured at the present value of expected future benefit payments using the Deutsche National Bank interest curve. The fair value of our pension plan assets by asset category was as follows: United States Plans Non-United States Plans Fair Value Measurements Using Fair Value Measurements Using December 31, Quoted Significant Significant December 31, Quoted Significant Significant Asset Category Cash and cash equivalents (1) $ 0.4 $ — $ 0.4 $ — $ 0.4 $ 0.4 $ — $ — Equity securities: United States companies 12.7 12.7 — — — — — — International companies — — — — 17.8 17.8 — — Fixed income securities: Government bonds (2) 16.9 — 16.9 — 47.8 47.8 — — Corporate bonds 7.2 — 7.2 — 31.2 31.2 — — Guaranteed insurance contracts — — — — 38.9 — 38.9 — Annuity contract — — — — 51.9 — 51.9 — Other types of investments: Unitized funds (3) — — — — 26.4 26.4 — — Insurance contracts — — — — 92.0 — — 92.0 Real estate funds — — — — 8.3 — 8.3 — $ 37.2 $ 12.7 $ 24.5 $ — $ 314.7 $ 123.6 $ 99.1 $ 92.0 (1)This category includes a prime obligations money market portfolio.

The reconciliation of the changes in the plan’s benefit obligation and the statement of the funded status of the plan were as follows: Year Ended December 31 2015 2014 Change in Benefit Obligation Benefit obligation, beginning of year $ 17.8 $ 18.5 Interest cost 0.7 0.8 Actuarial (gain) loss (0.5 ) 0.2 Benefits paid (1.6 ) (1.9 ) Plan participant contributions — 0.1 Retiree drug subsidy reimbursement — 0.1 Benefit obligation, end of year $ 16.4 $ 17.8 Funded Status at End of Year Funded status, end of year $ (16.4 ) $ (17.8 ) Amounts Recognized Current liabilities $ (1.3 ) $ (1.3 ) Noncurrent liabilities (15.1 ) (16.5 ) Net amount recognized $ (16.4 ) $ (17.8 ) The amount recognized in accumulated other comprehensive loss, net of tax, consists of a net loss of $1.7 and $2.0 for 2015 and 2014 , respectively, and a prior service credit of $6.0 and $6.5 in 2015 and 2014 , respectively. In June 2013, the Board of Directors approved an amendment related to the post-65 healthcare benefits of the plan that became effective as of July 1, 2014. The plan change included the introduction of a Health Reimbursement Account for Medicare eligible retirees and dependents. The plan change was communicated to retirees in October 2013, and the plan was re-measured as of October 1, 2013 to reflect this amendment. The discount rate used in the measurement of the benefit obligation was 4.3% and 3.9% in 2015 and 2014 , respectively. The discount rate used in the measurement of net periodic benefit cost was 3.9% and 4.7% in 2015 and 2014 , respectively, and 3.9% (January through September) and 4.8% (October through December) in 2013 . The components of net periodic benefit cost and other amounts recognized in other comprehensive loss (income) for this plan were as follows: 2015 2014 2013 Net Periodic Benefit Cost Interest cost $ 0.7 $ 0.8 $ 1.1 Net loss 0.1 0.1 0.3 Prior service credit (0.8 ) (0.8 ) (0.2 ) Net periodic benefit cost — 0.1 1.2 Other Changes in Plan Assets and Benefit Obligations Recognized in Other Comprehensive Loss (Income) Net (gain) loss (0.5 ) 0.2 (0.9 ) Prior service credit — — (11.2 ) Amortization of net loss (0.1 ) (0.1 ) (0.3 ) Amortization of prior service credit 0.8 0.8 0.2 Total recognized in other comprehensive loss (income) 0.2 0.9 (12.2 ) Total recognized in net periodic benefit cost and other comprehensive loss (income) $ 0.2 $ 1.0 $ (11.0 ) The estimated net loss and prior service credit for the retiree health care plan that will be amortized from accumulated other comprehensive loss into net periodic benefit cost during 2016 is $0.1 and $0.8 , respectively. The health care cost trend rate is assumed to be 7.3% for 2016 , decreasing gradually to an ultimate rate of 5.0% in 2022 . Assumed health care cost trend rates could have a significant effect on the amounts reported. A one-percentage point change in the assumed health care cost trend rate would have the following effects: 1% Increase 1% Decrease Effect on total of service and interest cost components $ — $ — Effect on benefit obligation 0.3 (0.3 ) Future Contributions and Payments During 2016 , we plan to contribute $11.6 to our pension plans and to fund our retiree health care payments as incurred. Projected benefit payments from the plans as of December 31, 2015 were estimated as follows: Year Pension Plans Retiree Health Care Plan 2016 $ 9.3 $ 1.3 2017 9.7 1.3 2018 10.3 1.3 2019 10.6 1.2 2020 12.4 1.1 2021–2025 75.7 5.4 Total projected benefit payments $ 128.0 $ 11.6 Defined Contribution Plans and Deferred Compensation Plans We have defined contribution plans covering substantially all permanent United States employees and various other employees throughout the world. Employees may elect to contribute a portion of their salary to the plans and we match a portion of their contributions up to a maximum percentage of the employee’s salary. In addition, profit sharing contributions are made if a targeted earnings level is reached. The total expense for our match and any profit sharing contributions was $19.6 , $19.8 and $22.4 for the years ended December 31, 2015 , 2014 and 2013 , respectively. We also have deferred compensation plans in the United States. One of the plans had an asset and liability of $82.9 and $80.0 as of December 31, 2015 and 2014 , respectively.

Derivative Instruments and Hedging Activities Disclosure [Abstract]
Derivative Financial Instruments	Derivative Financial Instruments We are exposed to various risks relating to our ongoing business operations. The primary risks, which are managed through the use of derivative instruments, are foreign currency exchange rate risk and interest rate risk. 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 manage interest rate risk through the use of a combination of fixed and variable rate borrowings. In accordance with the current accounting guidance for derivative instruments and hedging activities, we record all of our derivative instruments as either an asset or liability measured at their fair values. Foreign Currency Exchange Rate Risk Management A portion of the €400.0 Notes ( $431.0 ) and €350.0 ( $379.2 ) Notes were designated as economic hedges of our net investment in our foreign subsidiaries with a euro-functional currency as of December 31, 2015 . For derivatives designated as an economic hedge of the foreign currency exposure of a net investment in a foreign operation, the gain or loss associated with foreign currency translation is recorded as a component of accumulated other comprehensive loss, net of taxes. As of December 31, 2015 , we had a $14.1 unrealized gain included in accumulated other comprehensive loss, net of taxes, as the net investment hedge was deemed effective. On occasion, forward contracts are designated as an economic hedge of our net investment in our foreign subsidiaries. As of December 31, 2015 , we had a translation loss of $4.1 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. We recorded a gain of $0.6 associated with our forward contracts in interest and other expenses for the year ended December 31, 2015 , which offset the net loss recorded for the items noted above. The fair value measurements of these items recorded in our Consolidated Balance Sheets as of December 31, 2015 and 2014 are disclosed in Note 1 to the Consolidated Financial Statements.

Contingencies

Commitments and Contingencies Disclosure [Abstract]
Contingencies	Contingencies Litigation In the normal course of business, the Company is named as defendant in various legal proceedings in which claims are asserted against the Company. We record accruals for loss contingencies based on the circumstances of each claim, when it is probable that a loss has been incurred as of the balance sheet date and can be reasonably estimated. Although the outcome of litigation cannot be predicted with certainty, we believe the ultimate resolution of these legal proceedings will not have a material effect on our business or financial condition. In 2014, we recorded legal costs of $9.0 in the United States related to a settlement agreement in connection with a lawsuit in California involving allegations regarding our wage statements. The settlement agreement was approved by the court at a final hearing in June 2015. We believe that the settlement was in our best interest to avoid the costs and disruption of ongoing litigation. Guarantees We have entered into certain guarantee contracts and stand-by letters of credit that total $190.2 ( $144.7 for guarantees and $45.5 for stand-by letters of credit) as of December 31, 2015 . The guarantees primarily relate to operating leases and indebtedness. The stand-by letters of credit relate to insurance requirements and debt facilities. If certain conditions were met under these arrangements, we would be required to satisfy our obligation in cash. Due to the nature of these arrangements and our historical experience, we do not expect to make any significant payments under these arrangements.

Segment Reporting [Abstract]
Segment Data	Segment Data 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. We develop and implement global workforce solutions for our clients that deliver the outcomes that help them achieve their business strategy. 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 the placement of contingent workers. The remaining revenues within these segments are derived from other workforce solutions and services, including recruitment and assessment, training and development, and ManpowerGroup Solutions. ManpowerGroup Solutions includes Talent Based Outsourcing (TBO), TAPFIN - Managed Service Provider (MSP), Recruitment Process Outsourcing (RPO) and Proservia. The Right Management segment revenues are derived from career management and workforce consulting services. Segment revenues represent sales to external clients. Due to the nature of our business, we generally do not have export sales. We provide services to a wide variety of clients, none of which individually comprise a significant portion of revenues for us as a whole. The accounting policies of the segments are the same as those described in the summary of significant accounting policies. We evaluate performance based on operating unit profit, which is equal to segment revenues less direct costs and branch and national headquarters operating costs. This profit measure does not include goodwill and intangible asset impairment charges or amortization of intangible assets related to acquisitions, interest and other income and expense amounts or income taxes. Total assets for the segments are reported after the elimination of investments in subsidiaries and intercompany accounts.

Summary of Significant Accoun26

Summary of Significant Accounting Policies (Policies)	12 Months Ended
	Dec. 31, 2015
Accounting Policies [Abstract]
Use of Estimates	Use of Estimates The preparation of financial statements in conformity with accounting principles generally accepted in the United States requires us 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 for the reporting period. Actual results could differ from these estimates.
Basis of Consolidation	Basis of Consolidation The Consolidated Financial Statements include our operating results and the operating results of all of our majority-owned subsidiaries and entities in which we have a controlling financial interest. We have a controlling financial interest if we own a majority of the outstanding voting common stock and the noncontrolling shareholders do not have substantive participating rights, or we have significant control over an entity through contractual or economic interests in which we are the primary beneficiary. For subsidiaries in which we have an ownership interest of 50% or less, but more than 20%, the Consolidated Financial Statements reflect our ownership share of those earnings using the equity method of accounting. These investments, as well as certain other relationships, are also evaluated for consolidation under the accounting guidance on consolidation of variable interest entities. These investments were $137.9 and $132.3 as of December 31, 2015 and 2014 , respectively, and are included in other assets in the Consolidated Balance Sheets. Included in shareholders’ equity as of December 31, 2015 and 2014 are $85.4 and $77.4 , respectively, of unremitted earnings from investments accounted for using the equity method. All significant intercompany accounts and transactions have been eliminated in consolidation.
Revenues and Receivables	Revenues and Receivables We generate revenues from sales of services by our company-owned branch operations and from fees earned on sales of services by our franchise operations. Revenues are recognized as services are performed. The majority of our revenues are generated by our recruitment business, where billings are generally negotiated and invoiced on a per-hour basis. Accordingly, as contingent workers are placed, we record revenues based on the hours worked. Permanent recruitment revenues are recorded as placements are made. Provisions for sales allowances, based on historical experience, are recognized at the time the related sale is recognized. Our franchise agreements generally state that franchise fees are calculated based on a percentage of revenues. We record franchise fee revenues monthly based on the amounts due under the franchise agreements for that month. Franchise fees, which are included in revenues from services, were $24.2 , $25.4 and $24.4 for the years ended December 31, 2015 , 2014 and 2013 , respectively. In our outplacement business, we recognize revenues from individual programs and for large projects over the estimated period in which services are rendered to candidates. In our consulting business, revenues are recognized upon the performance of the service under the consulting service contract. For performance-based contracts, we defer recognizing revenues until the performance criteria have been met. The amounts billed for outplacement, consulting services and performance-based contracts in excess of the amount recognized as revenues are recorded as deferred revenue and included in accrued liabilities for the current portion and other long-term liabilities for the long-term portion in our Consolidated Balance Sheets. As of December 31, 2015 and 2014 , deferred revenue was $38.4 and $35.5 , respectively, all of which was current. W e record revenues from sales of services and the related direct costs in accordance with the accounting guidance on reporting revenue gross as a principal versus net as an agent. In situations where we act as a principal in the transaction, we report gross revenues and cost of services. When we act as an agent, we report the revenues on a net basis. Amounts billed to clients for out-of-pocket or other cost reimbursements are included in revenues from services, and the related costs are included in cost of services.
Allowance for Doubtful Accounts	Allowance for Doubtful Accounts We have an allowance for doubtful accounts recorded as an estimate of the accounts receivable balance that may not be collected. This allowance is calculated on an entity-by-entity basis with consideration for historical write-off experience, the current aging of receivables and a specific review for potential bad debts. Items that affect this balance mainly include bad debt expense and the write-off of accounts receivable balances. Bad debt expense is recorded as selling and administrative expenses in our Consolidated Statements of Operations and was $16.3 , $18.9 and $24.1 in 2015 , 2014 and 2013 , respectively. Factors that would cause this provision to increase primarily relate to increased bankruptcies by our clients and other difficulties collecting amounts billed. On the other hand, an improved write-off experience and aging of receivables would result in a decrease to the provision. Write-offs were $20.3 , $15.8 and $26.4 for 2015 , 2014 and 2013 , respectively.
Advertising Costs	Advertising Costs We expense production costs of advertising as they are incurred. Advertising expenses were $28.8 , $25.7 and $22.3 in 2015 , 2014 and 2013 , respectively.
Restructuring Costs	Restructuring Costs We recorded net restructuring costs of $16.4 and $89.4 in 2015 and 2013, respectively, in selling and administrative expenses, primarily related to severances and office closures and consolidations in multiple countries and territories. During 2015 and 2014 , we made payments of $12.9 and $35.5 , respectively, out of our restructuring reserve. We expect a majority of the remaining $16.4 reserve will be paid by the end of 2016 . Changes in the restructuring liability balances for each reportable segment and Corporate are as follows: Americas (1) Southern Europe (2) Northern Europe APME Right Management Corporate Total Balance, January 1, 2014 $ 6.8 $ 4.5 $ 22.2 $ 1.8 $ 12.3 $ 0.8 $ 48.4 Costs paid or utilized (5.7 ) (2.2 ) (16.4 ) (1.3 ) (10.0 ) 0.1 (35.5 ) Balance, December 31, 2014 1.1 2.3 5.8 0.5 2.3 0.9 12.9 Severance costs 2.5 — 8.6 0.9 1.1 — 13.1 Office closure costs 0.7 — 0.4 2.0 0.2 — 3.3 Costs paid or utilized (0.8 ) (0.6 ) (6.3 ) (1.7 ) (2.8 ) (0.7 ) (12.9 ) Balance, December 31, 2015 $ 3.5 $ 1.7 $ 8.5 $ 1.7 $ 0.8 $ 0.2 $ 16.4 (1) Balance related to United States was $5.1 as of January 1, 2014. In 2014 , United States paid/utilized $4.1 , leaving a $1.0 liability as of December 31, 2014 . In 2015 , United States incurred $2.3 for severance costs and $0.7 for office closure costs and paid/utilized $1.1 , leaving a $2.9 liability as of December 31, 2015 . (2) Balance related to France was $3.5 as of January 1, 2014. In 2014 , France paid/utilized $1.4 , leaving a $2.1 liability as of December 31, 2014 . In 2015 , France paid/utilized $0.6 , leaving a $1.5 liability as of December 31, 2015 . Italy had a $0.9 liability as of January 1, 2014. In 2014 , Italy paid/utilized $0.9 , leaving no liability as of December 31, 2014 or 2015 .
Income Taxes	Income Taxes We account for income taxes in accordance with the accounting guidance on income taxes. Deferred tax assets and liabilities are recognized for the future tax consequences attributable to differences between financial statement carrying amounts of existing assets and liabilities and their respective tax basis, and net operating loss and tax credit carryforwards. Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled. We record a valuation allowance against deferred tax assets to reduce the assets to the amounts more likely than not to be realized.
Fair Value Measurements	Fair Value Measurements The assets and liabilities measured and recorded at fair value on a recurring basis were as follows: Fair Value Measurements Using Fair Value Measurements Using December 31, 2015 Quoted Prices in Active Markets for Identical Assets (Level 1) Significant Other Observable Inputs (Level 2) Significant Unobservable Inputs (Level 3) December 31, 2014 Quoted Prices in Active Markets for Identical Assets (Level 1) Significant Other Observable Inputs (Level 2) Significant Unobservable Inputs (Level 3) Assets Foreign currency forward contracts $ 0.1 $ — $ 0.1 $ — $ 0.1 $ — $ 0.1 $ — Deferred compensation plan assets 84.1 84.1 — — 81.4 81.4 — — $ 84.2 $ 84.1 $ 0.1 $ — $ 81.5 $ 81.4 $ 0.1 $ — Liabilities Foreign currency forward contracts $ 0.5 $ — $ 0.5 $ — $ — $ — $ — $ — $ 0.5 $ — $ 0.5 $ — $ — $ — $ — $ — 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 third parties. The carrying values of cash and cash equivalents, accounts receivable, accounts payable, and other current assets and liabilities approximate their fair values because of the short-term nature of these instruments. The carrying value of our variable-rate long-term debt approximates fair value. The fair value of the euro-denominated notes, as observable at commonly quoted intervals (Level 2 inputs), was $858.2 and $471.6 as of December 31, 2015 and 2014 , respectively, compared to a carrying value of $810.2 and $422.1 , respectively.
Goodwill and Other Intangible Assets	Goodwill and Other Intangible Assets We have goodwill, finite-lived intangible assets and indefinite-lived intangible assets as follows: 2015 2014 December 31 Gross Accumulated Amortization Net Gross Accumulated Amortization Net Goodwill (1) $ 1,257.4 $ — $ 1,257.4 $ 1,075.2 $ — $ 1,075.2 Intangible assets: Finite-lived: Technology $ — $ — $ — $ 19.6 $ 19.6 $ — Franchise agreements — — — 18.0 18.0 — Customer relationships 425.6 256.7 168.9 359.9 225.6 134.3 Other 16.9 9.9 7.0 14.2 13.0 1.2 442.5 266.6 175.9 411.7 276.2 135.5 Indefinite-lived: Tradenames (2) 54.0 — 54.0 54.0 — 54.0 Reacquired franchise rights 96.6 — 96.6 97.3 — 97.3 150.6 — 150.6 151.3 — 151.3 Total intangible assets $ 593.1 $ 266.6 $ 326.5 $ 563.0 $ 276.2 $ 286.8 (1) Balances were net of accumulated impairment loss of $513.4 as of both December 31, 2015 and 2014 . (2) Balances were net of accumulated impairment loss of $139.5 as of both December 31, 2015 and 2014 . Amortization expense related to intangibles was $32.8 , $33.4 and $34.1 in 2015 , 2014 and 2013 , respectively. Amortization expense expected in each of the next five years related to acquisitions completed as of December 31, 2015 is as follows: 2016 - $34.8 , 2017 - $31.8 , 2018 - $29.0 , 2019 - $24.7 and 2020 - $20.2 . The weighted-average useful lives of the customer relationships and other are 13 and 4 years, respectively. The tradenames have been assigned an indefinite life based on our expectation of renewing the tradenames, as required, without material modifications and at a minimal cost, and our expectation of positive cash flows beyond the foreseeable future. The reacquired franchise rights result from our franchise acquisitions in the United States and Canada completed prior to 2009. In accordance with the accounting guidance on goodwill and other intangible assets, we perform an annual impairment test of goodwill at our reporting unit level and indefinite-lived intangible assets at our unit of account level during the third quarter, or more frequently if events or circumstances change that would more likely than not reduce the fair value of our reporting units below their carrying value. We performed our annual impairment test of our goodwill and indefinite-lived intangible assets during the third quarter of 2015 , 2014 and 2013 , and there was no impairment of our goodwill or indefinite-lived intangible as a result of our annual tests. We utilize a two-step method for determining goodwill impairment. In the first step, we determined the fair value of each reporting unit, generally by utilizing an income approach derived from a discounted cash flow methodology. For certain of our reporting units, a combination of the income approach (weighted 75% ) and the market approach (weighted 25% ) derived from comparable public companies was utilized. The income approach is developed from management’s forecasted cash flow data. Therefore, it represents an indication of fair market value reflecting management’s internal outlook for the reporting unit. The market approach utilizes the Guideline Public Company Method to quantify the respective reporting unit’s fair value based on revenues and earnings multiples realized by similar public companies. The market approach is more volatile as an indicator of fair value as compared to the income approach. We believe that each approach has its merits. However, in the instances where we have utilized both approaches, we have weighted the income approach more heavily than the market approach because we believe that management’s assumptions generally provide greater insight into the reporting unit’s fair value. Significant assumptions used in our goodwill impairment tests during 2015 , 2014 and 2013 included: expected revenue growth rates, operating unit profit margins, working capital levels, discount rates ranging from 11.8% to 17.1% for 2015 , and a terminal value multiple. The expected future revenue growth rates and the expected operating unit profit margins were determined after considering our historical revenue growth rates and operating unit profit margins, our assessment of future market potential, and our expectations of future business performance. If the reporting unit’s fair value is less than its carrying value, we are required to perform a second step. In the second step, we allocate the fair value of the reporting unit to all of the assets and liabilities of the reporting unit, including any unrecognized intangible assets, in a “hypothetical” calculation to determine the implied fair value of the goodwill. The impairment charge, if any, is measured as the difference between the implied fair value of the goodwill and its carrying value. Under the current accounting guidance, we are also required to test our indefinite-lived intangible assets for impairment by comparing the fair value of the intangible asset with its carrying value. If the intangible asset’s fair value is less than its carrying value, an impairment loss is recognized for the difference.
Marketable Securities	Marketable Securities We account for our marketable security investments in accordance with the accounting guidance on investments in debt and equity securities, and have historically determined that all such investments are classified as available-for-sale. Accordingly, unrealized gains and unrealized losses that are determined to be temporary, net of related income taxes, are included in accumulated other comprehensive loss, which is a separate component of shareholders’ equity. Realized gains and losses, and unrealized losses determined to be other-than-temporary, are recorded in our Consolidated Statements of Operations. We hold a 49% interest in our Swiss franchise, accounted for under the equity method of accounting, which maintained an investment portfolio with a market value of $202.3 and $200.9 as of December 31, 2015 and 2014 , respectively. This portfolio is comprised of a wide variety of European and United States debt and equity securities as well as various professionally-managed funds, all of which are classified as available-for-sale. Our share of net realized gains and losses, and declines in value determined to be other-than-temporary, are included in our Consolidated Statements of Operations. For the years ended December 31, 2015 , 2014 and 2013 , realized gains totaled $2.3 , $2.5 and $3.6 , respectively, and realized losses totaled $1.1 , $0.5 and $1.4 , respectively. Other-than-temporary impairment amounts for 2015 and 2013 were net gains of $0.2 and $0.9 , respectively, as previously impaired investments were sold for a gain, and 2014 was a loss of $0.1 . Our share of net unrealized gains and unrealized losses that are determined to be temporary related to these investments are included in accumulated other comprehensive loss, with the offsetting amount increasing or decreasing our investment in the franchise.
Capitalized Software for Internal Use	Capitalized Software for Internal Use We capitalize purchased software as well as internally developed software. Internal software development costs are capitalized from the time the internal use software is considered probable of completion until the software is ready for use. Business analysis, system evaluation, selection and software maintenance costs are expensed as incurred. Capitalized software costs are amortized using the straight-line method over the estimated useful life of the software which ranges from 3 to 10 years. The net capitalized software balance of $5.1 and $5.3 as of December 31, 2015 and 2014 , respectively, is included in other assets in the Consolidated Balance Sheets. Amortization expense related to the capitalized software costs was $1.7 , $2.2 and $5.6 for 2015 , 2014 and 2013 , respectively.
Property and Equipment	Property and Equipment A summary of property and equipment as of December 31 is as follows: 2015 2014 Land $ 5.4 $ 5.7 Buildings 16.7 19.2 Furniture, fixtures, and autos 166.6 178.2 Computer equipment 133.2 153.0 Leasehold improvements 263.5 277.4 Property and equipment $ 585.4 $ 633.5 Property and equipment are stated at cost and are depreciated using primarily the straight-line method over the following estimated useful lives: buildings - up to 40 years; furniture, fixtures, autos and computer equipment - 2 to 16 years; leasehold improvements - lesser of life of asset or expected lease term. Expenditures for renewals and betterments are capitalized whereas expenditures for repairs and maintenance are charged to income as incurred. Upon sale or disposition of property and equipment, the difference between the unamortized cost and the proceeds is recorded as either a gain or a loss and is included in our Consolidated Statements of Operations. Long-lived assets are evaluated for impairment in accordance with the provisions of the accounting guidance on the impairment or disposal of long-lived assets.
Derivative Financial Instruments	Derivative Financial Instruments We account for our derivative instruments in accordance with the accounting guidance on derivative instruments and hedging activities. Derivative instruments are recorded on the balance sheet as either an asset or liability measured at their fair value. If the derivative is designated as a fair value hedge, the changes in the fair value of the derivative and of the hedged item attributable to the hedged risk are recognized in earnings. If the derivative is designated as a cash flow hedge, the effective portions of the changes in the fair value of the derivative are recorded as a component of accumulated other comprehensive loss and recognized in the Consolidated Statements of Operations when the hedged item affects earnings. The ineffective portions of the changes in the fair value of cash flow hedges are recognized in earnings.
Foreign Currency Translation	Foreign Currency Translation The financial statements of our non-United States subsidiaries have been translated in accordance with the accounting guidance on foreign currency translation. Under the accounting guidance, asset and liability accounts are translated at the current exchange rates and income statement items are translated at the average exchange rates each month. The resulting translation adjustments are recorded as a component of accumulated other comprehensive loss, which is included in shareholders’ equity. A portion of our euro-denominated notes are accounted for as a hedge of our net investment in our subsidiaries with a euro-functional currency. Since our net investment in these subsidiaries exceeds the amount of the related borrowings, net of tax, all translation gains or losses related to these borrowings are included as a component of accumulated other comprehensive loss.
Shareholders' Equity	In October 2015 and December 2012, the Board of Directors authorized the repurchase of 6.0 million and 8.0 million shares of our common stock, respectively. 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. In 2015, we repurchased a total of 6.7 million shares, comprised of 6.0 million shares under the 2012 authorization and 0.7 million shares under the 2015 authorization, at a total cost of $587.9 , including a nominal amount of shares at a cost of $7.7 that settled in January 2016. The share repurchases that settled in January are not reflected in the treasury stock in our Consolidated Balance Sheets as of December 31, 2015 . In 2014, we repurchased 2.0 million shares under the 2012 authorization at a cost of $143.5 . No repurchases were made in 2013 . As of December 31, 2015 , there were 5.3 million shares remaining authorized for repurchase under the 2015 authorization and no shares remaining under the 2012 authorization. During 2015 , 2014 and 2013 , the Board of Directors declared total cash dividends of $1.60 , $0.98 and $0.92 per share, respectively, resulting in total dividend payments of $121.0 , $77.3 and $72.0 , respectively.
Noncontrolling Interests	During the third quarter of 2015, we entered into a joint venture to expand our business in the Greater China region. We contributed a majority of the net assets of our China, Hong Kong, Macau and Taiwan operations and the noncontrolling shareholder contributed cash. The joint venture is included in our Consolidated Balance Sheets as of December 31, 2015 as we have a controlling financial interest. The noncontrolling equity interest is included in noncontrolling interests in total shareholders’ equity in our Consolidated Balance Sheets as of December 31, 2015. Noncontrolling interests also includes amounts related to other majority-owned subsidiaries for which we have a controlling financial interest. Net earnings, net of tax, attributable to these noncontrolling interests were $6.6 for the year ended December 31, 2015.
Cash and Cash Equivalents	Cash and Cash Equivalents We consider all highly liquid investments with an original maturity of three months or less when purchased to be cash equivalents.
Payroll Tax Credit	Payroll Tax Credit In January 2013, the French government passed legislation, Credit d’Impôt pour la Compétitivité et l’Emploi (“CICE”), effective January 1, 2013, that provides payroll tax credits based on a percentage of wages paid to employees receiving less than two-and-a-half times the French minimum wage. The payroll tax credit was equal to 4% of eligible wages in 2013 and 6% of eligible wages in 2014 and beyond. The CICE payroll tax credit is accounted for as a reduction of our cost of services in the period earned. The payroll tax credit is creditable against our current French income tax payable, with any remaining amount being paid after three years. Given the amount of our current income taxes payable, we would generally receive the vast majority of these payroll tax credits after the three-year period. In July 2015 and December 2013, we entered into an agreement to sell a portion of the credits earned in 2014 and 2013, respectively, for net proceeds of $132.8 ( €120.1 ) and $104.0 ( €75.8 ), respectively. We derecognized these receivables upon the sale 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 as a reduction of the payroll tax credits earned in the respective years in cost of services.
Recently Issued Accounting Standards	Recently Issued Accounting Standards In May 2014, the FASB issued new accounting guidance on revenue from contracts with customers. The core principle of this amendment is that an entity should recognize revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. The original guidance was effective for us in 2017; however in August 2015, the FASB issued guidance that deferred the effective date by one year for all entities. The new guidance is effective for us in 2018 and can be adopted either retrospectively to each prior reporting period presented or as a cumulative-effect adjustment as of the date of adoption, with early adoption permitted, but not before the original effective date. We are currently assessing the impact of the adoption of this guidance on our Consolidated Financial Statements. In April 2015, the FASB issued new accounting guidance on debt issuance costs. The new guidance requires debt issuance costs related to a recognized debt liability to be presented in the balance sheet as a direct deduction from the associated liability, consistent with debt discounts. As of September 2015, we adopted this guidance and reclassified debt issuance costs associated with our long-term debt from other assets to long-term debt in prior-period financial statements to conform to the current period's presentation. The impact of the adoption of this guidance is disclosed in Note 7 to the Consolidated Financial Statements. In September 2015, the FASB issued new accounting guidance on business combinations. The new guidance eliminates the requirement to restate prior period financial statements for measurement period adjustments following a business combination. It requires that the cumulative impact of a measurement period adjustment (including the impact on prior periods) be recognized in the reporting period in which the adjustment is identified. The prior period impact of the adjustment should be either presented separately on the face of the income statement or disclosed in the notes. The guidance is effective for us in 2016. We do not expect the adoption of this guidance to have a material impact on our Consolidated Financial Statements. In November 2015, the FASB issued new accounting guidance on the balance sheet classification of deferred taxes. The new guidance requires that all deferred taxes be presented as noncurrent. In the fourth quarter of 2015, we adopted this guidance and reclassified current deferred tax assets and current deferred tax liabilities from future income tax benefits and accrued liabilities, respectively, to other assets and other long-term liabilities, respectively, in prior-period financial statements to conform to the current period's presentation. The impact of the adoption of this guidance is disclosed in Note 5 to the Consolidated Financial Statements. In January 2016, the FASB issued new accounting guidance on financial instruments. The new guidance changes the accounting for equity investments, financial liability under the fair value option and the presentation and disclosure requirements for financial instruments. The guidance is effective for us in 2018. We do not expect the adoption of this guidance to have a material impact on our Consolidated Financial Statements.
Reclassification	Reclassification In connection with the adoption in the third quarter of 2015 of the new accounting guidance on debt issuance costs, we have reclassified certain amounts in prior-period financial statements to conform to the current period's presentation. In our Consolidated Balance Sheets, we have reclassified debt issuance costs associated with our long-term debt from other assets to long-term debt (see Note 7 to the Consolidated Financial Statements). In connection with the adoption in the fourth quarter of 2015 of the new accounting guidance on balance sheet classification of deferred taxes, we have reclassified certain amounts in prior-period financial statements to conform to the current period's presentation. In our Consolidated Balance Sheets, we have reclassified current deferred tax assets and current deferred tax liabilities from future income tax (expense) benefits and accrued liabilities, respectively, to other assets and other long-term liabilities, respectively (see Note 5 to the Consolidated Financial Statements).
Subsequent Events	Subsequent Events We have evaluated events and transactions occurring after the balance sheet date through our filing date and noted no events that are subject to recognition or disclosure.
