Accounting Policies [Abstract]

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 nearly 2,800 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 France, the United States, the United Kingdom and Italy. 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 $145.8 and $137.9 as of December 31, 2016 and 2015, respectively, and are included in other assets in the Consolidated Balance Sheets. Included in shareholders’ equity as of December 31, 2016 and 2015 are $88.9 and $85.4, respectively, of unremitted earnings from investments accounted for using the equity method. All significant intercompany accounts and transactions have been eliminated in consolidation.

Revenues

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 $23.3, $24.2 and $25.4 for the years ended December 31, 2016, 2015 and 2014, 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, 2016 and 2015, the current portion of deferred revenue was $38.7 and $38.4, respectively, and the long-term portion of deferred revenue was $2.4 and zero, respectively. The increase in these amounts is primarily related to new client contracts in 2016.

We 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 $20.4, $16.3 and $18.9 in 2016, 2015 and 2014, 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 $16.9, $20.3 and $15.8 for 2016, 2015 and 2014, respectively.

Advertising Costs

We expense production costs of advertising as they are incurred. Advertising expenses were $24.4, $28.8 and $25.7 in 2016, 2015 and 2014, respectively.

Restructuring Costs

We recorded net restructuring costs of $16.4 in 2015 in selling and administrative expenses, primarily related to severances and office closures and consolidations in multiple countries and territories. During 2016 and 2015, we made payments of $11.9 and $12.9, respectively, out of our restructuring reserve. We expect a majority of the remaining $4.5 reserve will be paid by the end of 2017. Changes in the restructuring liability balances for each reportable segment and Corporate were as follows:



	Americas⁽¹⁾			Southern Europe⁽²⁾			Northern Europe			APME			Right Management			Corporate			Total
Balance, January 1, 2015		$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

(1) Balance related to United States was $1.0 as of January 1, 2015. 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. In 2016, United States paid/utilized $2.5, leaving a $0.4 liability as of December 31, 2016.

(2) Balance related to France was $2.1 as of January 1, 2015. In 2015, France paid/utilized $0.6, leaving a $1.5 liability as of December 31, 2015. In 2016, France paid/utilized $0.2, leaving a $1.3 liability as of December 31, 2016. Italy had no restructuring reserves recorded as of either January 1, 2015, December 31, 2015 or December 31, 2016.

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, 2016		Quoted Prices in Active Markets for Identical Assets (Level 1)		Significant Other Observable Inputs (Level 2)		Significant Unobservable Inputs (Level 3)		December 31, 2015		Quoted Prices in Active Markets for Identical Assets (Level 1)		Significant Other Observable Inputs (Level 2)		Significant Unobservable Inputs (Level 3)

		$0.2		$—		$0.2		$—		$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 $831.6 and $858.2 as of December 31, 2016 and 2015, respectively, compared to a carrying value of $785.2 and $810.2, respectively.

Goodwill and Other Intangible Assets

We had goodwill, finite-lived intangible assets and indefinite-lived intangible assets as follows:



	2016						2015
December 31	Gross		Accumulated Amortization		Net		Gross		Accumulated Amortization		Net
Goodwill⁽¹⁾	$	1,239.9	$	—	$	1,239.9	$	1,257.4	$	—	$	1,257.4

	150.8		—		150.8		150.6		—		150.6
Total intangible assets	$	594.2	$	299.8	$	294.4	$	593.1	$	266.6	$	326.5

(1) Balances were net of accumulated impairment loss of $513.4 as of both December 31, 2016 and 2015.

(2) Balances were net of accumulated impairment loss of $139.5 as of both December 31, 2016 and 2015.

Amortization expense related to intangibles was $36.0, $32.8 and $33.4 in 2016, 2015 and 2014, respectively. Amortization expense expected in each of the next five years related to acquisitions completed as of December 31, 2016 is as follows: 2017 - $32.6, 2018 - $29.7, 2019 - $25.8, 2020 - $20.9 and 2021 - $10.5. 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 2016, 2015 and 2014, 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 2016, 2015 and 2014 included: expected revenue growth rates, operating unit profit margins, working capital levels, discount rates ranging from 10.8% to 15.3% for 2016, 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 $207.0 and $202.3 as of December 31, 2016 and 2015, 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, 2016, 2015 and 2014, realized gains totaled $2.9, $2.3 and $2.5, respectively, and realized losses totaled $1.0, $1.1 and $0.5, respectively. Other-than-temporary impairment amounts were net gains of $0.3 and $0.2 for 2016 and 2015, respectively, as previously impaired investments were sold for a gain, and a loss of $0.1 in 2014. 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 $3.2 and $5.1 as of December 31, 2016 and 2015, respectively, is included in other assets in the Consolidated Balance Sheets. Amortization expense related to the capitalized software costs was $1.9, $1.7 and $2.2 for 2016, 2015 and 2014, respectively.

Property and Equipment

A summary of property and equipment as of December 31 is as follows:



	2016		2015
Land	$	5.5	$	5.4
Buildings	16.2		16.7
Furniture, fixtures, and autos	157.6		166.6
Computer equipment	117.8		133.2
Leasehold improvements	269.9		263.5
Property and equipment	$	567.0	$	585.4

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 13 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 is accounted for as a hedge of our net investment in our subsidiaries with a Euro-functional currency. For this portion of the Euro-denominated notes, since our net investment in these subsidiaries exceeds the amount of the related borrowings, net of tax, the related translation gains or losses are included as a component of accumulated other comprehensive loss.

Shareholders’ Equity

In July 2016, the Board of Directors authorized the repurchase of an additional 6.0 million shares of our common stock. This authorization was in addition to the October 2015 authorization to repurchase 6.0 million shares of our common stock and the December 2012 authorization to repurchase 8.0 million shares of our common stock. Share repurchases may be made from time to time through a variety of methods, including open market purchases, block transactions, privately negotiated transactions or similar facilities. In 2016, we repurchased a total of 6.6 million shares, comprised of 5.3 million shares under the 2015 authorization and 1.3 million shares under the 2016 authorization, at a total cost of $482.2. 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 were 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. As of December 31, 2016, there were 4.8 million shares remaining authorized for repurchase under the 2016 authorization and no shares remaining under either of the 2015 or 2012 authorizations.

During 2016, 2015 and 2014, the Board of Directors declared total cash dividends of $1.72, $1.60 and $0.98 per share, respectively, resulting in total dividend payments of $118.4, $121.0 and $77.3, 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 we have a controlling financial interest. The noncontrolling equity interest is included in noncontrolling interests in total shareholders’ equity in our Consolidated Balance Sheets.

Noncontrolling interests, included in total shareholders' equity in our Consolidated Balance Sheets, represent amounts related to majority-owned subsidiaries in which we have a controlling financial interest.

Net earnings attributable to these noncontrolling interests were $10.1 and $6.6 for the year ended December 31, 2016 and 2015, respectively, which were recorded as expenses in interest and other expenses in our Consolidated Statements of Operations.

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”), 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, 6% of eligible wages from 2014 to 2016, and 7% starting in 2017. 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 March 2016 and July 2015, we entered into an agreement to sell a portion of the credits earned in 2015 and 2014, respectively, for net proceeds of $143.1 (€129.9) and $132.8 (€120.1), 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. As amended, 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 2017. We are currently working through an adoption plan and completed a preliminary analysis of how we currently recognize revenue compared to the accounting treatment required under the new guidance. We will

complete our adoption plan in the first half of 2017. This plan includes a review of client contracts and revenue transactions to determine the impact of the accounting treatment under the new guidance, evaluation of the adoption method, and completing a rollout plan for the new guidance. Based on our preliminary analysis, we currently do not believe the adoption of this guidance will have a material impact on our Consolidated Financial Statements. We will continue to evaluate the impact of this guidance on our Consolidated Financial Statements and our preliminary assessments are subject to change. We plan to adopt the new guidance beginning January 1, 2018.

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. We adopted this guidance effective January 1, 2016. There was no impact of this adoption on our 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 are currently assessing the impact of the adoption of this guidance on our Consolidated Financial Statements.

In February 2016, the FASB issued new accounting guidance on leases. The new guidance requires that a lessee recognize assets and liabilities on the balance sheet for leases with lease terms longer than 12 months. The recognition, measurement and presentation of lease expenses and cash flows by a lessee will depend on its classification as a finance or operating lease. The guidance also includes new disclosure requirements providing information on the amounts recorded in the financial statements. The new guidance is effective for us in 2019. We are currently assessing the impact of the adoption of this guidance on our Consolidated Financial Statements.

In March 2016, the FASB issued new accounting guidance on employee share-based payment accounting. The new guidance is intended to simplify various aspects of the accounting for employee share-based payments, including the income tax consequences, classification of awards as either equity or liabilities, and classification on the statement of cash flows. The new guidance is effective for us in 2017. We do not expect the adoption of this guidance to have a material impact on our Consolidated Financial Statements.

In June 2016, the FASB issued new accounting guidance on financial instruments. The new guidance requires an application of an impairment model known as the current expected credit loss ("CECL") model to certain financial instruments. Using the CECL model, an entity recognizes an allowance for expected credit losses based on historical experience, current conditions, and forecasted information rather than the current methodology of delaying recognition of credit losses until it is probable a loss has been incurred. The new guidance is effective for us in 2020. We do not expect the adoption of this guidance to have a material impact on our Consolidated Financial Statements.

In August 2016, the FASB issued new accounting guidance on the cash flow statement. The new guidance is intended to reduce diversity in practice in how certain transactions are classified in the statement of cash flows. The new 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.

In October 2016, the FASB issued new accounting guidance on tax accounting for intra-entity asset transfers. Under current GAAP, the tax effects of intra-entity asset transfers are deferred until the transferred asset is sold to a third party or otherwise recovered through use, which is an exception to the principle that generally requires comprehensive recognition of current and deferred income taxes. The new guidance eliminates the exception for all intra-entity sales of assets other than inventory. As a result, an entity would recognize the tax expense from the sale of the asset in the seller’s tax jurisdiction when the transfer occurs, and any deferred tax asset that arises in the buyer’s jurisdiction would also be

recognized even though the pre-tax effects of that transaction are eliminated in consolidation. The guidance is effective for us in 2018. We are currently assessing the impact of the adoption of this guidance on our Consolidated Financial Statements.

In October 2016, the FASB issued new accounting guidance on consolidation. The new guidance amends the consolidation requirements that apply to a single decision maker’s evaluation of interests held through related parties that are under common control when it is determining whether it is the primary beneficiary of a variable interest entity (“VIE”). Under the new guidance, a reporting entity considers its indirect economic interests in a VIE held through related parties that are under common control on a proportionate basis, in a manner consistent with its consideration of its indirect economic interests held through related parties that are not under common control. The guidance is effective for us in 2017. We do not expect the adoption of this guidance to have a material impact on our Consolidated Financial Statements.

In January 2017, the FASB issued new guidance that revises the definition of a business. An integrated set of activities and assets (a “set”) is a business if it has, at a minimum, an input and a substantive process that together significantly contribute to the ability to create outputs. The new guidance provides a framework to evaluate when an input and a substantive process are present. To be a business without outputs, there will now need to be an organized workforce. The FASB noted that outputs are a key element of a business and included more stringent criteria for sets without outputs. 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.

In January 2017, the FASB issued new guidance that simplifies the accounting for goodwill impairment. The new guidance removes Step 2 of the goodwill impairment test, which requires a hypothetical purchase price allocation. A goodwill impairment will now be the amount by which a reporting unit’s carrying value exceeds its fair value, not to exceed the carrying amount of goodwill. All other goodwill impairment guidance will remain largely unchanged. The guidance is effective for us in 2020; however an early adoption is permitted for any impairment tests performed after January 1, 2017. We do not expect the adoption of this guidance to have a material impact on our 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	12 Months Ended
Acquisitions	Dec. 31, 2016
Business Combinations [Abstract]
Acquisitions	Acquisitions From time to time, we acquire and invest in companies throughout the world, including franchises. The total cash consideration paid for acquisitions, net of cash acquired, for the years ended December 31, 2016, 2015 and 2014 was $57.6, $260.5 and $32.0, respectively. Goodwill and intangible assets resulting from the 2016 acquisitions, the majority of which took place in the Netherlands and Norway, were $24.4 and $6.6, respectively, as of December 31, 2016. On September 3, 2015, we acquired 7S Group GmbH (“7S”), for total consideration, net of cash acquired, of $140.4 (€125.3) plus contingent consideration based on the financial results of the company and other factors, which are being finalized. 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. The customer relationships were $41.4 (€38.1) and $36.0 (€34.2) as of December 31, 2015 and 2016, respectively. Total amortization expense related to this intangible asset in each of the next five years is $4.2. The fair value of $119.1 (€106.2), which was not directly attributable to any specific assets or liabilities, was assigned to goodwill as part of the Germany reporting unit. Goodwill and intangible assets resulting from the remaining 2015 acquisitions, the majority of which took place in Australia, Canada and the Netherlands, were $108.7 and $28.5, respectively, as of December 31, 2015.

- Definition

Share-Based Compensation Plans

12 Months Ended

Dec. 31, 2016

Disclosure of Compensation Related Costs, Share-based Payments [Abstract]

Share-Based Compensation Plans

We account for share-based payments according to the accounting guidance on share-based payments. During 2016, 2015 and 2014, we recognized $27.1, $31.1 and $40.6, 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 2016, 2015 and 2014 was $7.4, $16.9 and $12.2, respectively. Consideration received from share-based awards for 2016, 2015 and 2014 was $19.7, $70.1 and $25.5, respectively. The excess income tax benefit recognized related to share-based compensation awards, which is recorded in capital in excess of par value, for 2016, 2015 and 2014 was approximately $0.8, $7.4 and $4.6, 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, 2016 or 2015.

A summary of stock option activity is as follows:

	1,127	4.9		$66	756		$62

We have recognized expense of $3.0, $3.2 and $6.8 related to stock options for the years ended December 31, 2016, 2015 and 2014, respectively. The total fair value of options vested during the same periods was $2.5, $3.2 and $11.1, respectively. As of December 31, 2016, total unrecognized compensation cost was approximately $3.0, 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	2016		2015		2014
Average risk-free interest rate	1.4	%	1.6	%	1.8	%
Expected dividend yield	2.1	%	1.5	%	1.2	%
Expected volatility	33.0	%	32.0	%	37.0	%
Expected term (years)	6.0		6.0		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 $19.68, $21.66 and $25.64 in 2016, 2015 and 2014, 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, 2016, 2015 and 2014, there were 39,805, 36,091 and 33,985, 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, 2016, 2015 and 2014, there were 8,388, 7,920 and 5,199, respectively, shares of deferred stock and 9,966, 13,860 and 10,248, 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 $1.1, $0.8 and $0.7 related to deferred stock in 2016, 2015 and 2014, 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, 2014	627			$54	1.3

Vested	(172	)	62
Forfeited	(14	)	76
Unvested, December 31, 2016	451			$70	1.4		$40

During 2016, 2015 and 2014, we recognized $13.8, $9.9 and $12.9, respectively, of expense related to restricted stock awards. As of December 31, 2016, there was approximately $13.1 of total unrecognized compensation cost related to unvested restricted stock, which we expect to recognize over a weighted-average period of approximately 2.0 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	2014	2015	2016
Grant Date(s)	February 14, 2013	February 11, 2014 and May 1, 2014	February 11, 2015	February 16, 2016

Units Forfeited in 2016 (at Target Award level)	—	10,928	7,796	—
Shares Issued in 2016	56,059	—	—	—

(a) 2014, 2015 and 2016 awards are scheduled to vest in February 2017, 2018, and 2019, respectively, when the Executive Compensation and Human Resources Committee of the Board of Directors determines the achievement of the performance criteria.

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 $9.1, $17.1 and $20.1 in 2016, 2015 and 2014, 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 for shares purchased under the plan in each of 2016, 2015 and 2014.

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	2016			2015			2014
Income tax based on statutory rate		$245.5			$231.2			$238.6

Included in non-United States tax rate difference are benefits of $1.8, $1.5 and $2.8 for 2016, 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	2016			2015
Future Income Tax (Expense) Benefits

We had United States Federal and non-United States net operating loss carryforwards and United States state net operating loss carryforwards totaling $350.0 and $256.8, respectively, as of December 31, 2016. The net operating loss carryforwards expire as follows:



	United States Federal and Non-United States		United States State

2021	4.4		—
Thereafter	23.4		243.7
No expirations	309.5		—
Total net operating loss carryforwards		$350.0		$256.8

We have recorded a deferred tax asset of $92.7 as of December 31, 2016, 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 $75.9 has been recorded as of December 31, 2016, as management believes that realization of certain net operating loss carryforwards is unlikely.

Pre-tax earnings of non-United States operations were $482.2, $511.2 and $485.9 in 2016, 2015 and 2014, respectively. We have not provided United States income taxes or non-United States withholding taxes on $555.3 of unremitted earnings of non-United States subsidiaries that are considered to be permanently invested. As of December 31, 2016, deferred taxes are provided on $774.7 of unremitted earnings of non-United States subsidiaries that may be remitted to the United States. As of December 31, 2016 and 2015, we have recorded a deferred tax liability of $164.8 and $132.0, respectively, related to these non-United States earnings that may be remitted.

As of December 31, 2016, we had gross unrecognized tax benefits related to various tax jurisdictions, including interest and penalties, of $44.0 that would favorably affect the effective tax rate if recognized. Our unrecognized tax benefits may decrease over the next 12 months pending resolution of certain tax audits during this time.

As of December 31, 2015, we had gross unrecognized tax benefits related to various tax jurisdictions, including interest and penalties, of $38.9.

We recognize accrued interest and penalties related to unrecognized tax benefits in income tax expense. We accrued net interest and penalties of $0.3 and $12.1 in 2016 and 2015, respectively, and recorded a benefit of $0.6 in 2014.

The following table summarizes the activity related to our unrecognized tax benefits during 2016, 2015 and 2014:



	2016			2015			2014

Potential interest and penalties	20.2			19.9			7.8
Balance, end of year		$44.0			$38.9			$30.8

We conduct business globally in various countries and territories. We are routinely audited by the tax authorities of the various tax jurisdictions in which we operate. Generally, the tax years that could be subject to examination are 2009 through 2016 for our major operations in France, Germany, Japan, the United Kingdom and the United States. As of December 31, 2016, we were subject to tax audits in Austria, Canada, Denmark, Germany, Italy, Portugal and the United States. We believe that the resolution of these audits will not have a material impact on earnings.

Debt

Information concerning short-term borrowings is as follows:

We maintain separate bank credit lines with financial institutions to meet working capital needs of our subsidiary operations. As of December 31, 2016, such uncommitted credit lines totaled $281.5, of which $241.3 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	2016		2015
Euro-denominated notes:
€400 due September 2022		$417.7		$431.0

Long-term debt		$785.6		$810.9

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 were used for general corporate purposes, including 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 may redeem the €400.0 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 €400.0 Notes.

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 the €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 these notes has been designated as a hedge of our net investment in subsidiaries with a Euro-functional currency as of December 31, 2016. For this portion of the Euro-denominated notes, since our net investment in these subsidiaries exceeds the respective amount of the designated borrowings, the related translation gains or losses are included as a component of accumulated other comprehensive loss. (See Note 12 to the Consolidated Financial Statements for further information.)

Revolving Credit Agreement

We have a Five Year Credit Agreement (the “Credit Agreement”) with a syndicate of commercial banks with a termination date of September 16, 2020. The Credit 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, 2016 and 2015. Outstanding letters of credit issued under the Credit Agreement totaled $0.8 and $0.9 as of December 31, 2016 and 2015, respectively. Additional borrowings of $599.2 and $599.1 were available to us under the facility as of December 31, 2016 and 2015, respectively.

Under the Credit 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 Credit 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 Credit 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.

Debt Maturities

The maturities of long-term debt payable within each of the four years subsequent to December 31, 2017 are as follows: 2018 — $367.8, 2019 — $0.1, 2020 — $0.0, 2021 — $0.0.

Retirement and Deferred Compensation Plans

Compensation and Retirement Disclosure [Abstract]

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-2016 projection scale in determining the plans’ benefit obligations as of December 31, 2016.

Beginning in 2016, we changed 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 had 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. For 2016, we utilized 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 made 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 resulted 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 was accounted for prospectively as a change in accounting estimate.

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.

Defined Benefit Pension Plans

We sponsor several qualified and nonqualified pension plans covering permanent employees. During 2016, we transitioned an additional German plan associated with the employees who were transferred in as part of a new client contract. The unfunded portion of this plan was $56.8 as of December 31, 2016 and will be funded by the client at the end of the contract. We have received a bank guarantee to cover the counterparty risk associated with this unfunded amount. 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:

The new German plan that we transferred in during 2016 was underfunded, resulting in the significant increase in the amounts above.

By their nature, certain of our plans do not have plan assets. The accumulated benefit obligation for these plans was $74.3 and $69.9 as of December 31, 2016 and 2015, respectively.

The components of the net periodic benefit cost and other amounts recognized in other comprehensive loss for all plans were as follows:

Effective July 1, 2016, we terminated a defined benefit plan in Northern Europe and transitioned our employees to a defined contribution plan, resulting in a curtailment and settlement gain of $6.9.

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 2017 are $1.8 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	2016		2015		2016		2015

Discount rate	4.0	%	4.3	%	2.2	%	3.2	%
Rate of compensation increase	3.0	%	3.0	%	1.7	%	2.2	%

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	2016		2015		2014		2016		2015		2014

Discount rate - service cost	4.4	%	3.9	%	4.6	%	3.2	%	2.9	%	4.1	%
Discount rate - interest cost	3.4	%	3.9	%	4.6	%	3.2	%	2.9	%	4.1	%
Expected long-term return on plan assets	5.3	%	5.5	%	6.0	%	3.4	%	3.2	%	4.5	%
Rate of compensation increase	3.0	%	3.0	%	3.0	%	2.2	%	2.6	%	3.8	%

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 2016 net periodic benefit cost on United States plan assets was 5.3%, while the rates of return on our non-United States plans varied by country and ranged from 1.7% to 4.3%. 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 four 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 2016 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 contracts and common contractual funds. The insurance contracts are measured at the present value of expected future benefit payments primarily using the Deutsche National Bank interest curve. For the common contractual funds, total fair value is based on significant unobservable inputs including assumptions where there is little, if any, market activity for the investment. Trust managers provide valuations of the investment. These valuations are reviewed for reasonableness and adjusted where appropriate, based on applicable market data.

The fair value of our pension plan assets by asset category was as follows:

The following table summarizes the changes in fair value of the pension assets that are measured using Level 3 inputs. In 2016, we transferred in common contractual funds as part of the pension assets associated with the new German plan. We determine that transfers between fair-value-measurement levels occur on the date of the event that caused the transfer.

Retiree Health Care Plan

We provide medical and dental benefits to certain eligible retired employees in the United States. Due to the nature of the plan, there are no plan assets. 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	2016			2015

The amount recognized in accumulated other comprehensive loss, net of tax, consists of a net loss of $1.7 for both 2016 and 2015, and a prior service credit of $5.4 and $6.0 in 2016 and 2015, respectively.

The discount rate used in the measurement of the benefit obligation was 4.0% and 4.3% in 2016 and 2015, respectively. The discount rate used in the measurement of net periodic benefit cost was 4.3%, 3.9% and 4.7% in 2016, 2015, and 2014, respectively. The components of net periodic benefit cost and other amounts recognized in other comprehensive loss for this plan were as follows:

Total recognized in other comprehensive loss	0.9			0.2			0.9

Total recognized in net periodic benefit cost and other comprehensive loss		$0.9			$0.2			$1.0

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 2017 is $0.1 and $0.8, respectively.

The health care cost trend rate is assumed to be 7.0% for 2017, 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:

Future Contributions and Payments

During 2017, we plan to contribute approximately $4.2 to our pension plans and to fund our retiree health care payments as incurred. Projected benefit payments from the plans as of December 31, 2016 were estimated as follows:



Year	Pension Plans		Retiree Health Care Plan

2017		$10.1		$1.3
2018	10.9		1.2

2021	13.8		1.1
2022–2026	89.0		5.2

Total projected benefit payments		$147.9		$11.1

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 $21.4, $19.6 and $19.8 for the years ended December 31, 2016, 2015 and 2014, respectively.

We also have deferred compensation plans in the United States. One of the plans had an asset and liability of $85.7 and $82.9 as of December 31, 2016 and 2015, respectively, with the remaining plans holding immaterial amounts of assets and liabilities.

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 have historically managed interest rate risk through the use of a combination of fixed and variable rate borrowings. In accordance with the current accounting guidance for derivative instruments and hedging activities, we record all of our derivative instruments as either an asset or liability measured at their fair value. Foreign Currency Exchange Rate Risk Management A portion of the €400.0 Notes ($417.7) and €350.0 ($367.5) Notes was designated as a hedge of our net investment in our foreign subsidiaries with a Euro-functional currency as of December 31, 2016. For this portion of the Euro-denominated notes, the gain or loss associated with foreign currency translation is recorded as a component of accumulated other comprehensive loss, net of taxes. As of December 31, 2016 and 2015, we had an unrealized gain of $29.0 and $14.1, respectively, included in accumulated other comprehensive loss, net of taxes, as the net investment hedge was deemed effective. On occasion, forward contracts are designated as a hedge of our net investment in our foreign subsidiaries. As of December 31, 2016 and 2015, we had a translation loss of $4.2 and $4.1, respectively, 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 loss of $1.6 for the year ended December 31, 2016 and a gain of $0.6 and $0.2 for the year ended December 31, 2015 and 2014, respectively, associated with our forward contracts in interest and other expenses, which partially offset the net gain for the year ended December 31, 2016 and net loss for the years ended December 31, 2015 and 2014 recorded for the items noted above. The fair value measurements of these items recorded in our Consolidated Balance Sheets as of December 31, 2016 and 2015 are disclosed in Note 1 to the Consolidated Financial Statements.

Contingencies	12 Months Ended
Contingencies	Dec. 31, 2016
Commitments and Contingencies Disclosure [Abstract]
Contingencies	Contingencies Litigation In the normal course of business, the Company is named as a 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 $177.6 ($130.7 for guarantees and $46.9 for stand-by letters of credit) as of December 31, 2016. 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

Effective January 1, 2016, we realigned our organizational structure in Europe. As a result, Other Southern Europe now includes several countries that were previously reported in Northern Europe. All previously reported results have been restated to conform to the current year presentation.

We are organized and managed primarily on a geographic basis, with Right Management currently operating as a separate global business unit. Each country and business unit generally has its own distinct operations and management team, providing services under our global brands, and maintains its own financial reports. We have an executive sponsor for each global brand who is responsible for ensuring the integrity and consistency of delivery locally. 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 ManpowerGroup Solutions (Recruitment Process Outsourcing (RPO), TAPFIN - Managed Service Provider (MSP), Proservia and Talent Based Outsourcing (TBO)), recruitment and assessment, and training and development. The Right Management segment revenues are derived from career management and talent management services. Segment revenues represent sales to external clients. We provide services to a wide variety of clients, none of which individually comprise a significant portion of revenues for us as a whole. Due to the nature of our business, we generally do not have export sales.

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, corporate expenses, 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.
