Revenue from Contracts with Cus

Revenue from Contract with Customer [Abstract]
Revenue from Contract with Customer [Text Block]	REVENUE FROM CONTRACTS WITH CUSTOMERS Revenue Recognition Policy More than 95% of the Company’s revenues are derived from fees for customer experience outsourcing services provided to the Company’s clients. Revenues from our contracts to provide these services relate to a single performance obligation to stand ready to provide services to the customer. The Company recognizes these revenues over time as services are performed based on the volumes of services provided and contractual rates. The Company’s remaining revenues, which represent less than 5% of the Company’s total revenues, are derived from the sale of premise-based and hosted self-care and technology solutions and provision of professional services. Revenues from the sale of these solutions and provision of these services are recognized over time as solutions or services are provided over the duration of the contract, using contractual rates. These contracts are typically one year or less in duration. Certain of our contracts, primarily for agent-related services, include pricing terms and conditions that include components of variable consideration. The variable consideration is typically in the form of performance-related bonus and penalty provisions that are determined based upon our meeting, or not meeting, agreed-upon service levels and performance metrics specified within the contract. Some contracts also contain discounts that the client can earn through the achievement of specified volume levels or through early payment for services provided by Convergys. Each component of variable consideration is earned based on the Company’s actual performance during the measurement period specified within the contract (typically monthly for bonus and penalty provisions and either quarterly or annually for volume discounts). In order to determine the transaction price, the Company estimates the variable consideration using the most likely amount method, based on the specific contract provisions and known performance results during the relevant measurement period. When determining if variable consideration should be constrained, the Company considers whether factors outside its control could result in a significant reversal of revenue. In making these assessments, the Company considers the likelihood and magnitude of a potential reversal. The Company’s performance period generally corresponds with the monthly invoice period. Given our historical experiences and relatively short duration of periods subject to variable consideration adjustments, no constraints on our revenue recognition were applied during the first quarter of 2018. The Company reassesses these estimates during each reporting period. Disaggregation of Revenue We provide services to companies across a variety of industries including communications, technology, retail, financial services, healthcare and other. The following table presents our disaggregated revenue from customers by key industry vertical for the three months ended March 31, 2018 and 2017 . Three Months Ended March 31, 2018 2017 Revenues: Communications $287.2 $336.8 Technology 148.9 156.5 Retail 76.4 66.4 Financial Services 74.7 77.9 Healthcare 51.4 51.4 Other 35.6 38.6 Total Revenues $674.2 $727.6 While most of our contracts are priced in U.S. dollars, we also recognize revenue under contracts that are denominated in euros, British pounds, Australian dollars or Canadian dollars. The following table presents the Company’s U.S. dollar equivalent revenue by currency for the three months ended March 31, 2018 and 2017 . Three Months Ended March 31, 2018 2017 U.S. Dollar Revenue by Currency: U.S. dollar $494.2 $570.1 Euro 92.3 77.7 British pound 52.7 39.8 Australian dollar 11.5 15.3 Canadian dollar 9.6 8.8 Other 13.9 15.9 Total Revenues $674.2 $727.6 Costs to Obtain a Contract The Company capitalizes commission expenses paid to our sales personnel when the commissions are deemed to be incremental for obtaining new agent-related services contracts. The deferred commissions are amortized on a straight-line basis over the expected period of benefit. We review the deferred commission balances for impairment on an ongoing basis. Deferred commissions are classified as current or noncurrent based on the timing of when we expect to recognize the expense. The current and noncurrent portions are included in Other current assets and Other assets, respectively, on the Company’s Consolidated Balance Sheets. As of March 31, 2018 , the current and noncurrent assets related to deferred commissions totaled $2.3 and $2.5 , respectively. During the three months ended March 31, 2018 , we recorded $0.7 of amortization expense related to deferred commissions. This expense is classified in Selling, general and administrative expense on the Consolidated Statement of Income. Receivables and Allowance for Doubtful Accounts Trade receivables are comprised of amounts owed to the Company by clients and are presented net of an allowance for doubtful accounts. Contracts with individual clients determine when receivables are due, generally within 30 to 60 days, and whether interest is accrued on late payments. The allowance for doubtful accounts is the Company’s best estimate of the amount of probable credit losses in the Company’s existing accounts receivable balance. The Company regularly reviews the adequacy of its allowance for doubtful accounts. The Company determines the allowance based on historical write-off experience and current economic conditions and also considers factors such as customer credit, past transaction history with the customer and changes in customer payment terms when determining whether the collection of a receivable is reasonably assured. Account balances are charged off against the allowance after all means of collection have been exhausted and the potential for recovery is considered remote. Volume Discounts Certain contracts with customers contain discounts that the client can earn through the achievement of specified volume levels or through early payment for services provided by Convergys. The Company maintains a liability for these discounts within Payables and other current liabilities on its Consolidated Balance Sheets. The liabilities for these discounts totaled $5.9 as of March 31, 2018 .

Earnings Per Share [Abstract]
Earnings (Loss) Per Share and Shareholder's Equity	EARNINGS PER SHARE AND SHAREHOLDERS’ EQUITY Earnings per Share The following is a reconciliation of the numerator and denominator of the basic and diluted earnings per share (EPS) computations: Shares (in millions) Shares Net Income Per Share Amount Three Months Ended March 31, 2018 Basic EPS 91.6 $29.8 $0.33 Effect of dilutive securities: Stock-based compensation arrangements 0.9 — (0.01 ) Convertible Debt 5.7 — (0.02 ) Diluted EPS 98.2 $29.8 $0.30 Three Months Ended March 31, 2017 Basic EPS 94.4 $37.9 $0.40 Effect of dilutive securities: Stock-based compensation arrangements 0.9 — — Convertible Debt 5.2 — (0.02 ) Diluted EPS 100.5 $37.9 $0.38 The diluted EPS calculation for the three months ended March 31, 2018 excludes 0.3 performance-based restricted stock units granted in 2016, as the performance criteria has not yet been achieved, as well as 0.4 performance-based restricted stock units ( 0.1 and 0.3 granted in 2018 and 2017 , respectively), as performance criteria for the third year of the 2017 grants and the second and third years of the 2018 grants have not yet been fully defined, thereby precluding a grant for accounting purposes due to a lack of a mutual understanding of the terms of the stock-based awards. The diluted EPS calculation for the three months ended March 31, 2018 includes 5.7 shares associated with the Company’s convertible debt. As described more fully in Note 6, during 2009, the Company issued approximately $125.0 aggregate principal amount of 5.75% Junior Subordinated Convertible Debentures due 2029 (2029 Convertible Debentures). The 2029 Convertible Debentures were convertible, subject to certain conditions, into shares of the Company’s common stock at an initial implied conversion price of approximately $12.07 per share, or eighty-two and eighty-two hundredths shares per one thousand dollars in principal amount of debentures. The conversion rate is subject to adjustment for certain events outlined in the indenture governing the 2029 Convertible Debentures (the Indenture), including payment of dividends. As of March 31, 2018 , the implied conversion price for the 2029 Convertible Debentures was approximately $11.11 per share, or eighty-nine and ninety-seven hundredths shares per one thousand dollars in principal amount of debentures. Shareholders’ Equity The Company repurchased 0.7 of its common shares during the three months ended March 31, 2018 at an average price of $22.96 per share for a total of $16.2 . Based upon the timing of transactions, $0.3 of the shares repurchased during December 2017 settled during the first quarter of 2018. Additionally, $0.6 of the shares repurchased during March 2018 had not settled as of March 31, 2018 . These shares are excluded from outstanding shares at the end of the current quarter and were settled in cash during the second quarter of 2018. As of March 31, 2018 , the Company had the authority to repurchase $45.3 of outstanding common shares pursuant to the Board of Directors’ August 2015 authorization to increase the remaining authorized share repurchases to $250.0 in the aggregate. The timing and terms of any future transactions will depend on a number of considerations including market conditions, our available liquidity and capital needs, and limits on share repurchases that may be applicable under the covenants in our Credit Agreement. Dividends During 2017 and 2018 , the Company’s Board of Directors declared the following dividends per common share, which were paid by the Company on the payment dates listed below: Announcement Date Record Date Dividend Amount Payment Date February 22, 2017 March 24, 2017 $0.09 April 7, 2017 May 8, 2017 June 23, 2017 $0.10 July 7, 2017 August 8, 2017 September 22, 2017 $0.10 October 6, 2017 November 7, 2017 December 22, 2017 $0.10 January 5, 2018 February 21, 2018 March 23, 2018 $0.10 April 6, 2018 On May 8, 2018 , the Company announced that its Board of Directors declared a quarterly cash dividend of $0.11 per common share to be paid on July 6, 2018 to shareholders of record as of June 22, 2018 . The Board expects that future cash dividends will be paid on a quarterly basis. However, any decision to pay future cash dividends will be subject to Board approval, and will depend on the Company’s future earnings, cash flow, financial condition, financial covenants and other relevant factors.

Goodwill and Intangible Assets Disclosure [Abstract]
Goodwill And Other Intangible Assets and Long-Lived Assets	GOODWILL AND OTHER INTANGIBLE AND LONG-LIVED ASSETS Goodwill Goodwill was $942.8 at March 31, 2018 compared to $937.9 at December 31, 2017 . This increase was due to foreign currency translation. The Company tests goodwill for impairment annually as of October 1 and at other times if events have occurred or circumstances exist that indicate the carrying value of goodwill may no longer be recoverable. Goodwill impairment testing is performed at the reporting unit level, one level below the business segment. The Company’s reporting units are Customer Management - Agent Services and Customer Management - Customer Interaction Technology (CIT). As of March 31, 2018 and December 31, 2017 , all goodwill was held by the Customer Management - Agent Services reporting unit. The annual impairment test performed as of October 1, 2017 indicated that the fair value of the Customer Management - Agent Services reporting unit was substantially in excess of its carrying value. However, impairment charges could be required if a divestiture decision is made or other significant economic events occur with respect to the reporting unit. Subsequent to our October 1, 2017 annual impairment test, no indications of an impairment were identified. Other Intangible Assets The Company’s other intangible assets, primarily acquired through business combinations, are evaluated periodically if events or circumstances indicate a possible inability to recover their carrying amounts. No impairment charges were recognized in any period presented. As of March 31, 2018 and December 31, 2017 , the Company’s other intangible assets consisted of the following: March 31, 2018 Gross Carrying Amount Accumulated Amortization Net Customer relationships and other intangibles $487.8 ($205.0 ) $282.8 Trademarks 27.1 (27.1 ) — Software (classified within Property and equipment, net) 41.3 (41.3 ) — Total $556.2 ($273.4 ) $282.8 December 31, 2017 Customer relationships and other intangibles $484.6 ($198.0 ) $286.6 Trademarks 27.0 (26.3 ) 0.7 Software (classified within Property and equipment, net) 41.3 (41.3 ) — Total $552.9 ($265.6 ) $287.3 The customer relationship and other intangible assets are being amortized for 1 to 17 years. The remaining weighted average amortization period for customer relationships and other intangibles is approximately 12.0 years. Amortization of software is included within depreciation expense as the underlying assets are classified within property and equipment. Amortization expense for intangibles was $6.9 for the three months ended March 31, 2018 and is estimated to be approximately $25.6 for the year ended December 31, 2018 . The related estimated expense for the five subsequent fiscal years is as follows: For the year ended 2019 $24.9 For the year ended 2020 24.2 For the year ended 2021 22.5 For the year ended 2022 22.2 For the year ended 2023 22.2 Thereafter 148.1

Long-term Debt and Capital Lease Obligations [Abstract]
Debt and Capital Lease Obligations	DEBT AND CAPITAL LEASE OBLIGATIONS Debt and capital lease obligations consisted of the following: March 31, 2018 December 31, 2017 Term Loan, due 2019 $49.6 $99.3 Convertible Debentures, due 2029 66.0 65.5 Capital Lease Obligations 1.0 2.1 Accounts Receivable Securitization 165.0 103.0 Total debt 281.6 269.9 Less debt issuance costs 1.3 1.3 Total debt, net 280.3 268.6 Less current maturities 50.3 0.9 Long-term debt $230.0 $267.7 Credit Facility On January 11, 2017 (the Effective Date), the Company entered into a new credit agreement (Credit Agreement) and repaid all amounts outstanding and terminated all commitments under its previously existing credit agreement (Prior Credit Agreement) using initial borrowings under the Credit Agreement as well as borrowings under the Company’s asset securitization facility. The Credit Agreement consists of a $215.0 unsecured term loan facility (Term Loan), maturing on March 3, 2019 , and a $300.0 unsecured revolving credit facility (Revolving Credit Facility), maturing on January 11, 2022 . On the Effective Date, the Company drew $100.0 in initial borrowings under the Term Loan. A $1.0 extinguishment loss was recognized on the Effective Date and is included in Interest expense on the Consolidated Statement of Income for the three months ended March 31, 2017 . The Revolving Credit Facility may be extended for two additional one-year periods, subject to the satisfaction of certain conditions set forth in the Credit Agreement. In addition, aggregate borrowing capacity under the Credit Agreement may be increased by up to an additional $250.0 million by increasing the amount of the Revolving Credit Facility or by incurring additional term loans, in each case subject to the satisfaction of certain conditions set forth in the Credit Agreement, including the receipt of additional commitments for such increase. Borrowings outstanding under the Credit Agreement may be repaid from time to time without premium or penalty, other than customary breakage costs, if any. Borrowings outstanding under the Credit Agreement bear interest at a fluctuating rate per annum equal to, at the Company’s option, either (a) the applicable adjusted LIBOR plus a spread based on the Company’s total net leverage ratio, or (b) a base rate (equal to the higher of the Administrative Agent’s prime rate, the federal fund rate plus 0.50%, and the one-month adjusted LIBOR plus 1.0%) plus a spread based on the Company’s total net leverage ratio. The Company is also obligated to pay a commitment fee on a quarterly basis on the unused portion of the commitments under the Revolving Credit Facility based on the Company’s total net leverage ratio, which fee is currently 25 basis points. While amounts borrowed and repaid under the Revolving Credit Facility can be re-borrowed, amounts repaid under the Term Loan cannot be borrowed again under the Credit Agreement. The Credit Agreement contains certain affirmative and negative covenants, as well as terms and conditions that are customary for credit facilities of this type, including financial covenants for leverage and interest coverage ratios. The Company was in compliance with all covenants at March 31, 2018 . Total borrowing capacity remaining under the Revolving Credit Facility was $300.0 , with $50.0 outstanding on the Term Loan, and recorded as a current obligation at March 31, 2018 . The carrying value of the Term Loan at March 31, 2018 reflects a discount of $0.4 related to fees paid directly to the lenders at issuance. This discount is being amortized over the life of the Term Loan using the effective interest rate method ( 4.0% as of March 31, 2018 ), and is included in interest expense in the Consolidated Statements of Income. Subsequent to March 31, 2018 , the Company fully repaid the $50.0 outstanding balance on the Term Loan. Convertible Debentures During 2009, Convergys issued $125.0 aggregate principal amount of 5.75% Junior Subordinated Convertible Debentures due September 2029 (2029 Convertible Debentures) in exchange for $122.5 of 4.875% Unsecured Senior Notes due December 15, 2009, pursuant to an exchange offer. At the date of issuance, the Company recognized the liability component of the 2029 Convertible Debenture at its fair value of $56.3 . The liability component was recognized as the fair value of a similar instrument that did not have a conversion feature at issuance. The equity component, which is the value of the conversion feature at issuance, was recognized as the difference between the proceeds from the issuance of the debentures and the fair value of the liability component, after adjusting for the deferred tax impact of $32.7 . The 2029 Convertible Debentures were issued at a coupon rate of 5.75% , which was below that of a similar instrument that did not have a conversion feature. Therefore, the valuation of the debt component, using the income approach, resulted in a debt discount. The debt discount is being amortized over the life of a similar debt instrument without a conversion feature, which the Company determined to equal the contractual maturity of the 2029 Convertible Debentures. Amortization is based upon the effective interest rate method and is included in interest expense in the Consolidated Statements of Income. The 2029 Convertible Debentures, which pay a fixed rate of interest semi-annually, have a contingent interest component that will require the Company to pay additional interest if the trading price of the 2029 Convertible Debentures exceeds a specified threshold at specified times, commencing on September 15, 2019, as outlined in the Indenture. The maximum amount of contingent interest that will accrue is 0.75% per annum of the average trading price of the 2029 Convertible Debentures during the periods specified in the Indenture. The fair value of this embedded derivative was not significant at March 31, 2018 or December 31, 2017. The Company is not entitled to redeem the 2029 Convertible Debentures prior to September 15, 2019. On or after September 15, 2019, the Company may redeem for cash all or part of the 2029 Convertible Debentures at par value plus accrued but unpaid interest if certain trading conditions of the Company’s common shares are satisfied. The holders of the 2029 Convertible Debentures have the option to require redemption at par value plus accrued but unpaid interest upon the occurrence of a fundamental change, a defined term in the Indenture. The 2029 Convertible Debentures are convertible at the option of the holders on or after September 15, 2028 and prior to that date only under the following circumstances: (1) during any calendar quarter if the last reported sales price of the Company’s common shares for at least 20 trading days (whether or not consecutive) during a period of 30 consecutive trading days ending on the last trading day of the preceding calendar quarter is greater than or equal to 130% of the applicable conversion price (currently $14.45 ) for the 2029 Convertible Debentures on each applicable trading day (hereinafter referred to as the Sales Price Condition); (2) during the five business day period immediately following any five consecutive trading day period (the Measurement Period) in which, as determined following a request by a holder of 2029 Convertible Debentures as provided in the Indenture, the trading price per $1,000 principal amount of 2029 Convertible Debentures for each trading day of such Measurement Period was less than 98% of the product of the last reported sale price of the Company’s common shares and the applicable conversion rate for the 2029 Convertible Debentures on each such trading day; (3) if the Company elects to redeem any or all of the 2029 Convertible Debentures; or (4) upon the occurrence of specified corporate events pursuant to the terms of the Indenture. Upon conversion, the Company will pay cash up to the aggregate principal amount of the 2029 Convertible Debentures to be converted and pay or deliver, as the case may be, cash, common shares of the Company or a combination of cash and common shares of the Company, at the Company’s election, in respect of the remainder, if any, of the Company’s conversion obligation in excess of the aggregate principal amount of the 2029 Convertible Debentures being converted. The 2029 Convertible Debentures were convertible, subject to certain conditions, into common shares of the Company at an initial implied conversion price of approximately $12.07 per share, or eighty-two and eighty-two hundredths shares per one thousand dollars in principal amount of debentures. As of March 31, 2018 , the implied conversion price for the 2029 Convertible Debentures was approximately $11.11 per share, or eighty-nine and ninety-seven hundredths shares per one thousand dollars in principal amount of debentures. The conversion rate is subject to adjustment for certain events outlined in the Indenture, including payment of dividends. As of March 31, 2018 and December 31, 2017, the 2029 Convertible Debentures were convertible at the option of the holders. This conversion right was triggered upon satisfaction of the Sales Price Condition (the closing price of the Company’s common shares was greater than or equal to $14.45 , 130% of the conversion price of the 2029 Convertible Debentures at March 31, 2018 , for at least 20 of the 30 consecutive trading days ending on March 31, 2018 ). As a result, the equity component of the 2029 Convertible Debentures equal to $59.0 (the difference between the par value and carrying value of the 2029 Convertible Debentures at March 31, 2018 ) has been classified as temporary equity within the March 31, 2018 Consolidated Balance Sheet since this amount was considered redeemable. The Company will reassess the convertibility of the 2029 Convertible Debentures and the related balance sheet classification on a prospective basis. There have been no conversions of the 2029 Convertible Debentures through the date of this filing. Based on quoted market prices at March 31, 2018 , the fair value of the $125.0 aggregate principal amount of the Company’s 2029 Convertible Debentures is $264.1 . Asset Securitization Facility During January 2017, the Company amended the terms of its asset securitization facility collateralized by accounts receivable of certain of the Company’s subsidiaries. The amendment resulted in an increased purchase limit of $225.0 , with $90.0 and $135.0 expiring in January 2018 and January 2020, respectively. The asset securitization facility was further amended in January 2018 to extend the expiration date for the $90.0 purchase limit to January 2019. The asset securitization program is conducted through Convergys Funding Inc., a wholly-owned bankruptcy remote subsidiary of the Company. As of March 31, 2018 and December 31, 2017, Convergys had drawn $165.0 and $103.0 , respectively, in available funding from qualified receivables. Amounts drawn under this facility have been classified as long-term debt within the Consolidated Balance Sheets, based on the Company’s ability and intent to refinance on a long-term basis as of March 31, 2018 . At March 31, 2018 , future minimum payments of the Company’s debt and capital lease arrangements (exclusive of any debt discounts) are as follows: 2018 $ 0.6 2019 116.3 2020 99.1 2021 — 2022 — Thereafter 125.0 Total $ 341.0

Restructuring Charges [Abstract]
Restructuring	RESTRUCTURING 2018 Restructuring Company-wide restructuring program During the first quarter of 2018 , the Company initiated a restructuring plan to reduce headcount and consolidate certain contact centers to streamline the Company’s operations. This resulted in a total charge of $10.7 , comprised of $5.0 of severance expense associated with headcount reductions and $5.7 of facility-related charges. This expense is included in Restructuring charges on the Consolidated Statements of Income. The headcount reductions impacted approximately 350 employees and the related severance is expected to be substantially paid in cash by September 30, 2018. The remaining severance liability resulting from these restructuring actions, which is included in Payables and other current liabilities on the Consolidated Balance Sheet, was $3.8 as of March 31, 2018 . The facility-related charges are associated with five site closures and primarily represent the present value of contractually obligated future minimum lease payments and the full impairment of certain abandoned property and equipment. The fair value of these facility obligations was determined using the income approach through a discounted cash flow analysis, based on estimated future contractual costs associated with the impacted facilities, net of proceeds from any probable future sublease agreements. The Company utilized market data to determine the estimated proceeds from any future sublease agreements. The Company will continue to evaluate the estimates used in recording the facilities abandonment charge over the remaining lease period. Consequently, there may be additional reversals or charges relating to these facility closures in the future. The remaining liability related to these facility restructuring actions, which is included in Payables and other current liabilities on the Consolidated Balance Sheet, was $1.8 as of March 31, 2018 . CEO transition costs On January 25, 2018, the Company announced that Andrea Ayers will transition from her role as President and Chief Executive Officer (CEO) of Convergys. The Company and Ms. Ayers subsequently executed a Separation and Consulting Agreement, effective February 20, 2018. During the three months ended March 31, 2018 , the Company recorded CEO transition costs of $7.3 associated with certain components of cash and equity-based compensation payable to Ms. Ayers in connection with her separation from the Company, as well as consulting fees associated with the Company’s search process to identify a successor CEO. This expense is included in Restructuring charges on the Consolidated Statements of Income. The compensation payments related to this expense are subject to the terms and conditions of the Separation and Consulting Agreement and the timing of such payments will, in some cases, depend on the timing of Ms. Ayers’ separation from the Company. Other severance During the first quarter of 2018, the Company recorded other severance expense of $0.9 primarily related to headcount reductions resulting from certain client program completions. These actions impacted approximately 345 employees. This severance expense is included in Restructuring charges on the Consolidated Statements of Income and was fully paid in cash by March 31, 2018. 2017 Restructuring Company-wide restructuring program During the first quarter of 2017, the Company recorded restructuring expenses of $12.8 related to a company-wide initiative to reduce headcount and better align the Company’s resources, principally for corporate functions. The 2017 restructuring actions impacted approximately 315 employees. This expense is included in Restructuring charges on the Consolidated Statements of Income and is expected to be substantially paid in cash by December 31, 2018. The total remaining liability under these restructuring actions, which is included in Payables and other current liabilities on the Consolidated Balance Sheet, was $3.3 as of March 31, 2018 and $5.8 as of December 31, 2017. Other severance During 2017, the Company recorded other severance expense of $2.2 primarily related to headcount reductions resulting from certain client program completions.

Commitments And Contingencies	COMMITMENTS AND CONTINGENCIES Commitments At March 31, 2018 , the Company had outstanding letters of credit and bond obligations of $13.7 related to performance guarantees. The Company believes that any guarantee obligation that may arise will not be material. The Company also has future purchase commitments with telecommunication and transportation providers of $12.5 for the remainder of 2018 . Contingencies The Company, from time to time, is subject to various loss contingencies, including tax and legal contingencies that arise in the ordinary course of business. The Company accrues for a loss contingency when it is probable that a liability has been incurred and the amount of such loss can be reasonably estimated. At this time, the Company believes that any such contingencies, either individually or in the aggregate, will not have a materially adverse effect on the Company’s results of operations or financial condition. However, the outcome of litigation cannot be predicted with certainty, and unfavorable resolution of one or more pending matters could have a materially adverse impact on the Company’s results of operations or financial condition in the future.

Derivative Instruments and Hedging Activities Disclosure [Abstract]
Financial Instruments	FINANCIAL INSTRUMENTS Derivative Instruments The Company is exposed to a variety of market risks, including the effects of changes in foreign currency exchange rates and interest rates. The Company’s risk management strategy includes the use of derivative instruments to reduce the effects on its operating results and cash flows from fluctuations caused by volatility in currency exchange rates. The Company serves many of its U.S.-based clients using contact center capacity outside of the U.S. Although the contracts with these clients are typically priced in U.S. dollars, a substantial portion of the costs incurred to deliver services under these contracts are denominated in the local currency of the country where services are provided, which represents a foreign exchange exposure. The Company has hedged a portion of its exposure related to the anticipated cash flow requirements denominated in some of the aforementioned foreign currencies by entering into hedging contracts with several financial institutions to acquire a total of PHP 31,440.0 at a fixed price of $615.0 at various dates through December 2020 , INR 9,645.0 at a fixed price of $133.4 at various dates through December 2020 , CAD 56.1 at a fixed price of $42.8 at various dates through June 2020 and COP 56,400.0 at a fixed price of $18.5 at various dates through March 2020 , and to sell a total of AUD 30.6 at a fixed price of $23.9 at various dates through September 2019 . These instruments mature within the next 33 months and had a notional value of $819.6 at March 31, 2018 and $835.5 at December 31, 2017 . The derivative instruments discussed above are designated and are effective as cash flow hedges. The following table reflects the fair values of these derivative instruments: March 31, 2018 December 31, 2017 Forward exchange contracts and options designated as hedging instruments: Included within other current assets $9.9 $14.5 Included within other non-current assets 2.7 8.7 Included within other current liabilities 18.8 7.7 Included within other long-term liabilities 6.6 1.7 The Company recorded a deferred tax benefit of $3.2 and deferred tax expense of $3.6 related to these derivatives at March 31, 2018 and December 31, 2017 , respectively. A total of $9.7 of deferred losses, net of tax, related to these cash flow hedges were included in accumulated other comprehensive loss (OCL) at March 31, 2018 , compared to $10.4 of deferred gains, net of tax, that were included in accumulated other comprehensive income (OCI) at December 31, 2017 . As of March 31, 2018 , deferred losses of $9.0 ( $6.7 net of tax) on derivative instruments included in accumulated OCL are expected to be reclassified into earnings during the next 12 months. The following tables provide the effect of these derivative instruments on the Company’s Consolidated Financial Statements during the three months ended March 31, 2018 and 2017 , respectively: Three Months Ended March 31, 2018 : Derivatives in Cash Flow Hedging Relationships Gain (Loss) Recognized in OCL on Derivative (Effective Portion) Gain (Loss) Reclassified from Accumulated OCL into Income (Effective Portion) Location of Gain (Loss) Reclassified from Accumulated OCL into Income (Effective Portion) Foreign exchange contracts ($29.0 ) ($2.2 ) Cost of providing services and products sold and Selling, general and administrative Three Months Ended March 31, 2017 : Derivatives in Cash Flow Hedging Relationships Gain (Loss) Recognized in OCL on Derivative (Effective Portion) Gain (Loss) Reclassified from Accumulated OCL into Income (Effective Portion) Location of Gain (Loss) Reclassified from Accumulated OCL into Income (Effective Portion) Foreign exchange contracts $9.8 ($7.7 ) Cost of providing services and products sold and Selling, general and administrative The gain or loss recognized related to the ineffective portion of the derivative instruments was immaterial for the three months ended March 31, 2018 and 2017 . The Company also enters into derivative instruments (forwards) to economically hedge the foreign currency impact of assets and liabilities denominated in nonfunctional currencies. During the three months ended March 31, 2018 , a loss of $3.9 was recognized related to changes in fair value of these derivative instruments not designated as hedges, compared to a loss of $2.6 in the same period in 2017 . The gains and losses largely offset the currency gains and losses that resulted from changes in the assets and liabilities denominated in nonfunctional currencies. These gains and losses are classified within other income, net in the accompanying Consolidated Statements of Income. The fair value of these derivative instruments not designated as hedges at March 31, 2018 , was a $0.2 receivable. Short-term Investments As of March 31, 2018 and December 31, 2017 , the Company held investment securities with a fair value of $13.1 and $13.5 , respectively, that are held in a grantor trust for the benefit of participants in the EDCP and reflect the hypothetical investment balances of EDCP participants. The securities are classified as trading securities and included within short-term investments in the Consolidated Balance Sheets. The investment securities include exchange-traded mutual funds and money market accounts. These securities are carried at fair value, with gains and losses, both realized and unrealized, reported in other (expense) income, net in the Consolidated Statements of Income. The cost of securities sold is based upon the specific identification method. Interest and dividends on securities classified as trading are included in other (expense) income, net.

Fair Value Disclosures [Abstract]
Fair Value Disclosures	FAIR VALUE MEASUREMENTS U.S. GAAP defines a hierarchy which prioritizes the inputs in measuring fair value. The three levels of the fair value hierarchy are as follows: Level 1 inputs are quoted prices (unadjusted) in active markets for identical assets or liabilities; Level 2 inputs are quoted prices for similar assets and liabilities in active markets or inputs that are observable for the asset or liability, either directly or indirectly through market corroboration, for substantially the full term of the financial instrument; and Level 3 inputs are unobservable inputs based on the Company’s assumptions used to measure assets and liabilities at fair value. A financial asset or liability’s classification within the hierarchy is determined based on the lowest level input that is significant to the fair value measurement. At March 31, 2018 and December 31, 2017 , the Company had foreign currency forward contracts measured at fair value. The fair values of these instruments were measured using valuations based upon quoted prices for similar assets and liabilities in active markets (Level 2) and are valued by reference to similar financial instruments, adjusted for terms specific to the contracts. There were no transfers between the three levels of the fair value hierarchy during the years ended March 31, 2018 and March 31, 2017 . The derivative assets and liabilities measured at fair value on a recurring basis as of March 31, 2018 and December 31, 2017 were as follows: March 31, 2018 Quoted Prices In Active Markets for Identical Assets (Level 1) Significant Other Observable Inputs (Level 2) Significant Unobservable Inputs (Level 3) Derivatives: Foreign currency forward contracts (asset position) $13.0 $— $13.0 $— Foreign currency forward contracts (liability position) $25.8 $— $25.8 $— December 31, 2017 Quoted Prices Significant Significant Derivatives: Foreign currency forward contracts (asset position) $24.2 $— $24.2 $— Foreign currency forward contracts (liability position) $19.2 $— $19.2 $— The Company also had investment securities held in a grantor trust for the benefit of participants of the EDCP measured at fair value at March 31, 2018 and December 31, 2017 . These investments are recorded as short-term investments on the Consolidated Balance Sheets. The fair value of these instruments was measured using the quoted prices in active markets for identical assets (Level 1). There were no transfers between the three levels of the fair value hierarchy during the years ended March 31, 2018 and March 31, 2017 .

Income Taxes	INCOME TAXES The effective tax rate on net income from continuing operations was a benefit of 1.0% for the three months ended March 31, 2018 compared to expense of 15.4% in the same period last year. The effective tax rate for the three months ended March 31, 2018 was favorably impacted by a net benefit of $8.6 resulting from the resolution of certain tax audits. The effective tax rate for the three months ended March 31, 2018 was also impacted by the geographic mix of worldwide income and the accrual of withholding taxes on the repatriation of current period earnings. In the fourth quarter of 2017, the Company recorded an estimated net discrete tax charge of $34.1 related to the Tax Cuts and Jobs Act (the 2017 Tax Act) that was accounted for as a provisional charge in accordance with Staff Accounting Bulletin No. 118. During the three months ended March 31, 2018 , the Company recorded an adjustment of $1.4 to recognize the imposition of the new minimum tax on global intangible income, which the Company accounts for as a period cost. The Company continues to analyze the impacts of the 2017 Tax Act; therefore, the 2017 charge continues to be provisional. As of March 31, 2018 and December 31, 2017 , the liability for unrecognized tax benefits was $10.1 and $21.3 , respectively, and is included in other long-term liabilities in the accompanying Consolidated Balance Sheets. As of March 31, 2018, the total amount of unrecognized tax benefits that would affect income tax expense if recognized in the Consolidated Financial Statements is $8.6 . This amount includes net interest and penalties of $3.8 . It is reasonably possible that the total amount of unrecognized tax benefits will decrease between approximately $1.3 and $5.5 in the next twelve months; however, actual developments in this area could differ from those currently expected.

The Company elected to early adopt this standard as of January 1, 2018, on a prospective basis, resulting in a $6.0 reclassification adjustment, using a specific identification method, that increased retained earnings and decreased AOCI. In May 2017, the FASB issued ASU 2017-09, Stock Compensation - Scope of Modification Accounting . This ASU clarifies which changes to the terms or conditions of a share-based payment award require the application of modification accounting under ASC 718. The Company adopted this standard as of January 1, 2018. The adoption of this standard did not have an impact on the Company’s consolidated financial statements. In January 2017, the FASB issued ASU 2017-04, Simplifying the Test for Goodwill Impairment . This ASU eliminates the two-step process that required identification of potential impairment and a separate measure of the actual impairment. Goodwill impairment charges, if any, would be determined by the difference between a reporting unit's carrying value and its fair value (impairment loss is limited to the carrying value). This standard is effective for annual or any interim goodwill impairment tests beginning after December 15, 2019. The adoption of this standard is not expected to have a material impact on the Company’s consolidated financial statements. In August 2016, the FASB issued ASU 2016-15, Statement of Cash Flows (Topic 230) . The objective of this update is to provide additional guidance and reduce diversity in practice when classifying certain transactions within the statement of cash flows. In November 2016, the FASB issued ASU 2016-18, Statement of Cash Flows (Topic 230): Restricted Cash . This new standard requires that the statement of cash flows explain the change during the period in the total of cash, cash equivalents, and amounts generally described as restricted cash or restricted cash equivalents. These standards are effective for financial statements issued for fiscal years beginning after December 15, 2017, including interim periods within those fiscal years. The Company adopted these standards as of January 1, 2018 utilizing the retrospective transition method. The adoption of this standard did not have a material impact on the Company’s consolidated financial statements. In February 2016, the FASB issued ASU 2016-02, Leases . This ASU will require lessees to recognize almost all leases on the balance sheet as a right-of-use asset and a lease liability. For income statement purposes, the FASB retained a dual model, requiring leases to be classified as finance leases or operating leases. The Company will adopt this standard on January 1, 2019 and is currently assessing the effect that adoption of the new standard will have on its consolidated financial statements and related disclosures, as well as its processes, systems and internal controls. The Company currently expects adoption of this standard will result in a material increase to the assets and liabilities reported on the Company’s Consolidated Balance Sheets. In May 2014, the FASB issued ASU 2014-09, Revenue from Contracts with Customers . The standard applies one comprehensive revenue recognition model across all contracts, entities and sectors. The core principal of the new standard is that revenue should be recognized 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 standard includes cost guidance, whereby all direct and incremental costs to obtain or fulfill a contract with a customer are capitalized and amortized over the corresponding period of benefit. The Company adopted this standard for all contracts with customers outstanding on January 1, 2018 using the modified retrospective adoption method, which resulted in a $3.2 adjustment to the opening balance of retained earnings. Results for reporting periods after January 1, 2018 are presented under ASU 2014-09, while prior period amounts are not adjusted and continue to be reported in accordance with the accounting standards in effect for those periods. The largest adoption impacts to the Company’s consolidated financial statements resulted from the new qualitative and quantitative disclosures provided in Note 3, and the capitalization of certain direct and incremental contract costs that are now being capitalized and amortized over the estimated period of benefit of the corresponding contracts. The new standard does not have an impact on the timing or revenue recognition pattern of any of our identified revenue streams. The cumulative effect of the changes made to our January 1, 2018 Consolidated Balance Sheet for the adoption of ASU 2014-09 were as follows: Balance at Adjustments Due to Balance at Consolidated Balance Sheet Caption December 31, 2017 ASU 2014-09 January 1, 2018 Assets Other current assets $47.4 $2.0 $49.4 Total current assets $857.7 $2.0 $859.7 Other assets $50.5 $2.3 $52.8 Total Assets $2,414.7 $4.3 $2,419.0 Liabilities and Shareholders' Equity Deferred income tax liabilities $222.6 $1.1 $223.7 Total liabilities $977.5 $1.1 $978.6 Retained Earnings $1,457.8 $3.2 $1,461.0 Total shareholders' equity $1,377.7 $3.2 $1,380.9 Total Liabilities and Shareholders' Equity $2,414.7 $4.3 $2,419.0 The impacts to the Company’s Consolidated Statement of Income for the three months ended March 31, 2018 and Consolidated Balance Sheet as of March 31, 2018 , as a result of the adoption of ASU 2014-09 were as follows: Three Months Ended March 31, 2018 Consolidated Statement of Income Caption As Reported Amounts Without Adoption of ASU 2014-09 Effect of Change Selling, general and administrative $172.4 $172.8 ($0.4 ) Total costs and expenses $639.7 $640.1 ($0.4 ) Operating Income $34.5 $34.1 $0.4 Income before Income Taxes $29.5 $29.1 $0.4 Income tax benefit ($0.3 ) ($0.2 ) ($0.1 ) Net Income $29.8 $29.5 $0.3 Three Months Ended March 31, 2018 Consolidated Balance Sheet Caption As Reported Balances Without Adoption of ASU 2014-09 Effect of Change Assets Other current assets $49.9 $47.6 $2.3 Total current assets $856.5 $854.2 $2.3 Other assets $44.6 $42.1 $2.5 Total Assets $2,386.3 $2,381.5 $4.8 Liabilities and Shareholders' Equity Deferred income tax liabilities $213.4 $212.2 $1.2 Total liabilities $952.9 $951.7 $1.2 Retained earnings $1,488.1 $1,484.5 $3.6 Total shareholders' equity $1,374.4 $1,370.8 $3.6 Total Liabilities and Shareholders' Equity $2,386.3 $2,381.5 $4.8

Expense for the three months ended March 31, 2018 and 2017 included expense of $0.1 and an income adjustment of $0.1 , respectively, related to awards classified as liabilities that will ultimately settle in cash. The income adjustment in the prior year reflected a revaluation of the awards classified as liabilities based on the trading price of the Company’s common stock. Restricted Stock Units Time-based Restricted Stock Units During the three months ended March 31, 2018 and 2017 , the Company granted 0.4 and 0.2 shares, respectively, of time-based restricted stock units. The weighted average grant date fair values of these grants were $23.32 and $22.70 , respectively. These time-based grants are scheduled to vest 25% at the first anniversary of the grant date, 25% at the second anniversary and 50% at the third anniversary, with the exception of 0.2 granted in 2018 that are scheduled to vest 50% at the second anniversary and 50% at the third anniversary. The total compensation cost related to non-vested time-based restricted stock units not yet recognized as of March 31, 2018 was approximately $24.4 , which is expected to be recognized over a weighted average period of 2.4 years. Changes to non-vested time-based restricted stock units for the three months ended March 31, 2018 were as follows: Shares (in millions) Number of Shares Weighted Average Fair Value at Date of Grant Non-vested at December 31, 2017 1.3 23.46 Granted 0.4 23.32 Vested (0.4 ) 23.25 Forfeited — — Non-vested at March 31, 2018 1.3 $23.45 Performance-based Restricted Stock Units During the three months ended March 31, 2018 and 2017 , the Company granted 0.1 and 0.1 shares, respectively, of performance-based restricted stock units. These grants provide for payout based upon the extent to which the Company achieves certain EPS targets, as determined by the Compensation and Benefits Committee of the Board of Directors, over three-year periods. Payout levels for earned shares range from 50% to 200% of award shares. No payout is earned if performance is below the minimum threshold performance level. At March 31, 2018 , the targets for the third year of the 2017 grants and the second and third years of the 2018 grants had not yet been set, the key terms had not been effectively communicated to the recipients, and as such the expense related to these grants had not yet been recognized. These grants have been excluded from the table below. During the first quarter of 2018 , the Company established and communicated to participants the final key terms of the 2016 grants, resulting in grants for accounting purposes with a grant date fair value of $23.58 per share. The total compensation cost related to the 2016 non-vested performance-based restricted stock units not yet recognized as of March 31, 2018 was approximately $4.5 , which is expected to be recognized ratably over the remaining vesting period ending in February 2019.
