Accounting Policies [Abstract]
Significant Accounting Policies [Text Block]	SIGNIFICANT ACCOUNTING POLICIES Principles of Consolidation and Basis of Presentation The accompanying Consolidated Financial Statements have been prepared in accordance with accounting principles generally accepted in the United States of America and U.S. Securities and Exchange Commission regulations. The Consolidated Financial Statements include the accounts of the Company’s majority-owned subsidiaries. All material intercompany accounts and transactions are eliminated upon consolidation. Reclassification Certain prior year balances in the Consolidated Balance Sheet have been reclassified to conform to the current year presentation. The reclassifications were not material to the Consolidated Financial Statements. See New Accounting Pronouncements section for further discussion. Use of Estimates, Risks and Uncertainties The preparation of the Consolidated Financial Statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the amounts reported. These estimates include, but are not limited to, project completion dates, time and cost required to complete projects for purposes of revenue recognition and future revenue, expense and cash flow estimates for purposes of impairment analysis and loss contract evaluation. Actual results could differ from those estimates. The Company’s results are affected by economic, political, legislative, regulatory and legal actions. Economic conditions, such as recessionary trends, inflation, interest and monetary exchange rates, and government fiscal policies, can have a significant effect on operations. While the Company maintains reserves for anticipated liabilities and carries insurance in an amount and scope that the Company believes are appropriate, the Company could be adversely affected by civil, criminal, regulatory or administrative actions, claims or proceedings. Foreign Currency Translation Assets and liabilities of foreign operations are translated to U.S. dollars at year-end exchange rates. Revenues and expenses are translated at average exchange rates for the related period. Translation adjustments are accumulated and reflected as adjustments to other comprehensive (loss) income, a component of Shareholders’ Equity, and included in net earnings only upon sale or liquidation of the underlying foreign subsidiary. Gains or losses resulting from foreign exchange transactions related to balance sheet positions are recorded in the Consolidated Statements of Income within Other (expense) income, net. Revenue Recognition Revenues mostly consist of fees generated from outsourced services provided to the Company’s clients. More than 95% of the Company’s revenues are derived from agent-related services. The Company typically recognizes these revenues as services are performed based on staffing hours or the number of contacts handled by service agents using contractual rates. The remaining revenues are derived from the sale of premise-based and hosted automated self-care and technology solutions and provision of professional services. Revenues from the sale of these solutions and provision of services are typically recognized as services are provided over the duration of the contract using contractual rates. These contracts are typically one year or less in duration. Revenues are recognized only when the services are performed, there is evidence of an arrangement, the Company determines that the fee is fixed and determinable and collection of the fee included in the arrangement is considered probable. When determining whether the fee is considered fixed and determinable and collection is probable, the Company considers a number of factors including the creditworthiness of the client and the contractual payment terms. If a client is not considered creditworthy, recognition of all revenue under arrangements with that client is deferred until receipt of cash. If payment terms extend beyond what is considered customary or standard in the related industry and geographic location, recognition of the revenue is deferred until the related fees become due and payable. Certain contracts have performance-related bonus provisions that require the client to pay us a bonus based upon our meeting agreed-upon service levels and performance metrics. These bonuses are recognized only after required measurement targets are met and the other criteria for recognition are satisfied. Stock-Based Compensation The Company accounts for stock-based payment transactions in which the Company receives employee services in exchange for equity instruments of the Company. Stock-based compensation cost for restricted stock awards and restricted stock shares and performance restricted stock units is measured based on the closing fair market value of the Company’s common shares on the date of grant. Stock-based compensation cost for stock options is estimated at the grant date based on each option’s fair-value as calculated by the Black-Scholes option-pricing model. The Company recognizes stock-based compensation cost as expense for awards other than its performance-based restricted stock units ratably on a straight-line basis over the requisite service period. The Company recognizes stock-based compensation cost associated with its performance based restricted stock units over the requisite service period if it is probable that the performance conditions will be satisfied. The Company will recognize a benefit from stock-based compensation in equity if an incremental tax benefit is realized by following the ordering provisions of the tax law. Tax benefits related to stock compensation expense are reported as financing cash flow and tax expenses are reported as operating cash flow. Further, the Company applies an estimated forfeiture rate to unvested awards when computing the stock compensation-related expenses. Income Taxes The provision for income taxes includes taxes paid, currently payable or receivable, and those deferred. Under U.S. GAAP, the Company recognizes deferred tax assets and liabilities based on the differences between the financial statement and tax basis of assets and liabilities using enacted tax rates in effect for the year in which the differences are expected to be settled or realized. The Company regularly reviews its deferred tax assets for recoverability and establishes a valuation allowance if it is more likely than not that some portion or all of a deferred tax asset will not be realized. The determination as to whether a deferred tax asset will be realized is made on a jurisdictional basis and is based on the evaluation of positive and negative evidence. This evidence includes historical pre-tax and taxable income, projected future taxable income, the expected timing of the reversal of existing temporary differences and the implementation of tax planning strategies. Projected future taxable income is based on expected results and assumptions as to the jurisdiction in which the income will be earned. The expected timing of the reversals of existing temporary differences is based on current tax law and the Company’s tax methods of accounting. The Company also reviews its tax activities and evaluates uncertain tax positions using a two-step approach. The first step is to evaluate the tax position for recognition by determining if the weight of available evidence indicates that it is more likely than not that the position will be sustained on audit, including resolution of related appeals or litigation processes, if any. The second step is to measure the tax benefit, which is the largest amount that is more than 50% likely of being realized upon ultimate settlement. The Company’s policy is to recognize interest and penalties accrued on unrecognized tax benefits as part of income tax expense. Other Comprehensive Income (Loss) Components of other comprehensive income (loss) include currency translation adjustments, changes related to pension liabilities, net of tax, and unrealized gains (losses) on hedging activities, net of tax. Foreign currency translation adjustments generally are not adjusted for income taxes as they relate to indefinite investments in non-U.S. operations. Accumulated other comprehensive income (loss) also includes, net of tax, actuarial gains or losses, prior service costs or credits and transition assets and obligations that are not recognized currently as components of net periodic pension cost. Concentration of Credit Risk In the normal course of business, the Company is exposed to credit risk. The principal concentrations of credit risk are cash and cash equivalents, short-term investments, accounts receivable and derivative instruments. The Company regularly monitors credit risk exposures and takes steps to mitigate the likelihood of these exposures resulting in a loss. Historically, credit losses on accounts receivable have not been material because of the large concentration of revenues with a small number of large, established companies. The Company does not require collateral or other security to support accounts receivable. The Company evaluates the creditworthiness of its clients in conjunction with its revenue recognition processes, as discussed above, as well as through its ongoing collectability assessment processes for accounts receivable. The Company maintains an allowance for doubtful accounts receivable based upon factors surrounding the credit risk of specific clients, historical trends and other information. The Company limits its counterparty credit risk exposures by entering into derivative contracts with financial institutions that are investment grade rated. Cash and Cash Equivalents Cash and cash equivalents consist of cash on hand and short-term, highly liquid investments with original maturities of three months or less. Receivables and Allowance for Doubtful Accounts Trade receivables are comprised primarily of amounts owed to the Company by clients and are presented net of an allowance for doubtful accounts of $5.3 and $8.1 at December 31, 2015 and 2014 , respectively. Contracts with individual clients determine when receivables are due, generally within 30 - 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. 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. Property and Equipment Property and equipment are stated at cost. Depreciation is based on the straight-line method over the estimated useful lives of the assets. Buildings are generally depreciated over a 30 -year life, software over a three - to ten -year life and equipment generally over a three - to five -year life. Leasehold improvements are depreciated over the shorter of their estimated useful life or the remaining term of the associated lease. Assets held under capital leases are recorded at the lower of the net present value of the minimum lease payments or the fair value of the leased asset at the inception of the lease. Depreciation expense for assets held under captial lease is computed using the straight-line method over the shorter of the estimated useful lives of the assets or the period of the related lease. Included within Property and equipment is initial cost of $13.2 related to assets under capital lease arrangements. The Company reviews property and equipment asset groups for impairment whenever events or changes in circumstances indicate the carrying amount of an asset may not be recoverable. The Company monitors these changes and events on at least a quarterly basis. Examples of events or changes in circumstances could include, but are not limited to, a prolonged economic downturn, current period operating or cash flow losses combined with a history of losses or a forecast of continuing losses associated with the use of an asset group, or a current expectation that an asset group will be sold or disposed of before the end of its previously estimated useful life. Recoverability is based upon projections of anticipated future undiscounted cash flows associated with the use and eventual disposal of the property and equipment asset groups, as well as specific appraisals in certain instances. Reviews occur at the lowest level for which identifiable cash flows are largely independent of cash flows associated with other property and equipment asset groups. If the future undiscounted cash flows result in a value that is less than the carrying value, then the long-lived asset is considered impaired and a loss is recognized based on the amount by which the carrying amount exceeds the estimated fair value. Various factors that the Company uses in determining the impact of these assessments include the expected useful lives of long-lived assets and our ability to realize any undiscounted cash flows in excess of the carrying amounts of such asset groups, and are affected primarily by changes in the expected use of the assets, changes in technology or development of alternative assets, changes in economic conditions, changes in operating performance and changes in expected future cash flows. Because judgment is involved in determining the fair value of property and equipment asset groups, there is risk that the carrying value of these assets may require adjustment in future periods. Internal Use Software The Company capitalizes certain expenditures for software that is purchased or internally developed for use in the business. During 2015 , 2014 , and 2013 , amounts capitalized for internally developed software were $14.2 , $4.9 and $1.0 , respectively. The increase in capitalized costs during 2015 is a result of certain information technology infrastructure initiatives. Amortization of internal use software begins when the software is ready for service and continues on the straight-line method over the estimated useful life, generally ranging from three to ten years. Business Combinations Accounting for acquisitions requires the Company to recognize separately from goodwill the assets acquired and the liabilities assumed at their acquisition date fair values. Goodwill as of the acquisition date is measured as the excess of consideration transferred over the net of the acquisition date fair values of the assets acquired and the liabilities assumed. While we use our best estimates and assumptions to accurately value assets acquired and liabilities assumed at the acquisition date as well as contingent consideration, where applicable, our estimates are inherently uncertain and subject to refinement. As a result, during the measurement period, which may be up to one year from the acquisition date, we record adjustments to the assets acquired and liabilities assumed with corresponding adjustments to goodwill. Upon the conclusion of the measurement period or final determination of the values of assets acquired or liabilities assumed, whichever comes first, any subsequent adjustments are recorded to our consolidated statements of operations. Refer to Note 3 of the Notes to the Consolidated Financial Statements for a discussion of the Stream acquisition. Goodwill and Other Intangibles As discussed more fully in Note 6, goodwill is reviewed at the reporting unit level for impairment as of October 1 each year and at other times if events have occurred or circumstances exist that indicate the carrying value of goodwill may no longer be recoverable. The first step of the impairment test compares the fair value of a reporting unit with its carrying amount, including the goodwill allocated to the reporting unit (Step 1). If the fair value of the reporting unit is in excess of the carrying value, the related goodwill is considered not to be impaired and no further analysis is necessary. If the carrying amount of the reporting unit exceeds the fair value, there is an indication of potential impairment and a second step of testing is performed to measure the amount of the impairment, if any, for that reporting unit. When required, the second step compares the implied fair value of the reporting unit goodwill with the carrying amount of the reporting unit goodwill. The implied fair value of goodwill is determined in the same manner as the amount of goodwill recognized in a business combination, which is the excess of the fair value of the reporting unit determined in step one over the fair value of the net assets and identifiable intangibles as if the reporting unit were being acquired. Any excess of the carrying value of the reporting unit goodwill over the implied fair value of the reporting unit goodwill will be recorded as an impairment loss. An impairment charge recognized cannot exceed the amount of goodwill allocated to a reporting unit and cannot be reversed subsequently even if the fair value of the reporting unit recovers. Fair value of the reporting unit is determined using the income approach with corroboration from the market approach. Under the market approach, fair value is based on revenue and earnings multiples for guideline public companies in the reporting unit’s peer group. The market approach requires judgment regarding the selection of guideline companies. Under the income approach, value is dependent on the present value of net cash flows to be derived from ownership of the reporting unit. The income approach requires significant judgment including estimates about future cash flows and discount rates. Other intangibles, primarily customer relationship assets and trademarks, are amortized over a straight-line basis with estimated useful lives ranging from four to seventeen years and are evaluated periodically if events or circumstances indicate a possible inability to recover their carrying amounts. Postemployment Benefits The funded status of the Company’s pension and other postretirement benefit plans is recognized in the Consolidated Balance Sheets. The funded status is measured as the difference between the fair value of plan assets and the benefit obligation at December 31, the measurement date. For defined benefit pension plans, the benefit obligation is the projected benefit obligation (PBO) and, for the other postretirement benefit plans, the benefit obligation is the accumulated postretirement benefit obligation (APBO). The PBO represents the actuarial present value of benefits expected to be paid upon retirement. For active plans, the present value reflects estimated future compensation levels. The APBO represents the actuarial present value of postretirement benefits attributed to employee services already rendered. The fair value of plan assets represents the current market value of assets held by an irrevocable trust fund for the sole benefit of participants. The measurement of the benefit obligation is based on the Company’s estimates and actuarial valuations. These valuations reflect the terms of the plans and use participant-specific information such as compensation, age and years of service, as well as certain key assumptions that require significant judgment, including, but not limited to, estimates of discount rates, expected return on plan assets, rate of compensation increases, interest crediting rates and mortality rates. For additional information regarding plan assumptions and the current financial position of the pension and other postretirement plans, see Note 9. The Company provides severance benefits to certain employees. The Company accrues the benefits when it becomes probable that such benefits will be paid and when sufficient information exists to make reasonable estimates of the amounts to be paid. Government Grants From time to time, the Company receives grants from local or state governments as an incentive to locate or retain operations in their jurisdictions. Depending on the arrangement, the grants are either received up-front or at the time the Company achieves the milestones set forth in the grant. The Company’s policy is to record the grant funds received as deferred credit and to amortize the deferred credit as a reduction of cost of providing services and products sold or selling, general and administrative expense as the milestones are met over the term of the grant. Derivative Instruments 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 and interest rates. The Company currently uses only cash flow hedges. These instruments are hedges of forecasted transactions or of the variability of cash flows to be received or paid related to a recognized asset or liability. The Company generally enters into hedging contracts expiring within 36 months as hedges of anticipated cash flows denominated in foreign currencies. These contracts are entered into to protect against the risk that the eventual cash flows resulting from such transactions will be adversely affected by changes in exchange rates. In using derivative financial instruments to hedge exposures to changes in exchange rates, the Company exposes itself to counterparty credit risk. All derivatives, including foreign currency exchange contracts, are recognized in the Consolidated Balance Sheets at fair value. Fair values for the Company’s derivative financial instruments are based on quoted market prices of comparable instruments or, if none are available, on pricing models or formulas using current assumptions. On the date the derivative contract is entered into, the Company determines whether the derivative contract qualifies for designation as a hedge. For derivatives that are designated as hedges, the Company further designates the hedge as either a fair value or cash flow hedge; all currently existing hedges have been designated as cash flow hedges. Changes in the fair value of derivatives that are highly effective and designated as cash flow hedges are reported as a component of Other Comprehensive (Loss) Income and reclassified into earnings in the same line-item associated with the forecasted transaction and in the same periods during which the hedged transaction impacts earnings. The Company formally documents all relationships between hedging instruments and hedged items, as well as its risk management objective and strategy for undertaking various hedging activities. This process includes linking all derivatives that are designated as fair value or cash flow hedges to specific assets and liabilities on the balance sheet or to forecasted transactions, respectively. The Company also formally assesses, both at the hedge’s inception and on an ongoing basis, whether the derivatives that are used in hedging transactions are highly effective in offsetting changes in the fair value or cash flows of hedged items. When it is determined that a derivative is not highly effective as a hedge or that it has ceased to be a highly effective hedge, the Company discontinues hedge accounting prospectively. The Company also periodically enters into hedging contracts that are not designated as hedges. The purpose of the majority of these derivative instruments is to protect the Company against foreign currency exposure pertaining to receivables, payables and intercompany transactions that are denominated in currencies different from the functional currencies of the Company or the respective subsidiaries. The Company records changes in the fair value of these derivative instruments in the Consolidated Statements of Income within Other income, net. Investments Management determines the appropriate classification of securities at the time of purchase and re-evaluates such designation as of each balance sheet date. Currently all investment securities are classified as trading, and are reported within short-term investments in the Consolidated Balance Sheets. Trading 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 is included in Other (expense) income, net. Fair Value Measurements The Company applies fair value accounting for all financial assets and liabilities and non-financial assets and liabilities that are recognized or disclosed at fair value in the consolidated financial statements on a recurring basis. The Company defines fair value as the price that would be received from selling an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. When determining the fair value measurements for assets and liabilities, the Company considers the principal or most advantageous market in which the Company would transact and the market-based risk measurements or assumptions that market participants would use in pricing the asset or liability, such as inherent risk, transfer restrictions and credit risk. New Accounting Pronouncements In November 2015, the Financial Accounting Standards Board (FASB) issued Accounting Standards Update (ASU) 2015-17, “Balance Sheet Classification of Deferred Taxes.” This ASU requires all deferred tax assets and liabilities to be classified as non-current on the balance sheet instead of separating into current and non-current amounts. This update is effective for interim and annual periods beginning after December 15, 2016 and may be applied on a prospective or retrospective basis. The Company elected to early adopt this standard on a retrospective basis as of December 31, 2015. The impact of this change in accounting principle on balances previously reported as of December 31, 2014 was as follows: As of December 31, 2014 Consolidated Balance Sheet Caption Previously Reported Change Currently Reported Total current assets $ 890.9 (107.2 ) $ 783.7 Total Assets $ 2,516.5 (100.4 ) $ 2,416.1 Total current liabilities $ 368.5 (0.6 ) $ 367.9 Total Liabilities $ 1,225.0 (100.4 ) $ 1,124.6 In April 2015, the FASB issued ASU 2015-03, “Simplifying the Presentation of Debt Issuance Costs.” This ASU requires debt issuance costs to be presented in the balance sheet as a direct deduction from the carrying value of the associated debt liability, consistent with the presentation of a debt discount. This ASU is effective for interim and annual periods beginning after December 15, 2015 and is required to be applied retrospectively. This standard is not expected to have a material effect on the Company’s consolidated financial statements.

Business Combinations [Abstract]
Business Combination Disclosure [Text Block]	BUSINESS COMBINATIONS Stream Acquisition Background and Financing On January 6, 2014, the Company and its wholly-owned subsidiary (Merger Sub), entered into an Agreement and Plan of Merger (the Merger Agreement) with Stream and, for limited purposes, other Sellers listed in the Merger Agreement. On March 3, 2014 , Merger Sub was merged with and into Stream (the Merger), with Stream continuing as the surviving corporation and as a wholly owned subsidiary of Convergys. At the time of the Merger, each share of Stream common stock was converted into the right to receive an amount in cash, without interest. The total purchase price, net of cash acquired, was $802.6 , which was funded using available cash, borrowings under the Accounts Receivable Securitization Facility and proceeds from a $350.0 term loan under the Company’s February 28, 2014 Credit Agreement (the Credit Agreement) (see Note 7 for further discussion). The purchase price of Stream consisted of the following items: Cash consideration for Stream stock (1) $ 481.0 Cash consideration for Stream stock options (2) 16.1 Cash consideration for repayment of Stream 11.25% Senior Secured Notes (3) 243.0 Cash consideration for repayment of Stream 10.0% Promissory Notes (4) 19.3 Cash consideration for repayment of Stream Revolving Credit Facility (5) 63.4 Cash consideration for transaction expenses of Stream (6) 7.8 Total cash consideration 830.6 Cash acquired (7) (28.0 ) Net consideration transferred $ 802.6 (1) The cash consideration for the outstanding shares of Stream’s common stock, which includes final settlement for working capital. Stream outstanding common shares totaled 0.7 as of March 3, 2014. (2) The cash consideration paid for “in the money” stock option awards. (3) The cash consideration to repay Stream’s 11.25% Senior Secured Notes due 2014, which reflects the aggregate principal and interest amounts of $230.0 and $13.0 , respectively, as of March 3, 2014. (4) The cash consideration to repay Stream’s 10.0% Promissory Notes, which reflects the aggregate principal and interest amounts of $16.1 and $3.2 , respectively, as of March 3, 2014. (5) The cash consideration to repay Stream’s Revolving Credit Facility, which reflects the aggregate principal and interest amounts of $63.1 and $0.3 , respectively, as of March 3, 2014. (6) Pursuant to the Merger Agreement, Convergys reimbursed the holders of Stream common stock for expenses incurred by Stream in connection with the merger. These expenses primarily related to third-party consulting services. (7) Represents the Stream cash balance acquired at acquisition. The Company incurred $14.7 of transaction costs related to the Stream acquisition during 2014. These costs are included in Transaction and integration costs in the accompanying Consolidated Statements of Income. Purchase Price Allocation The Company accounted for Stream using the acquisition method of accounting in accordance with applicable U.S. GAAP whereby the total purchase price was allocated to tangible and intangible assets acquired and liabilities assumed based on respective fair values. The following table summarizes the assets acquired and liabilities assumed at the date of acquisition: March 3, 2014 Assets: Receivables $ 197.9 Other current assets 13.5 Property and equipment 159.3 Goodwill 276.5 Intangible assets 370.4 Other assets 7.9 Liabilities: Accounts payable $ (12.3 ) Accrued expenses (100.3 ) Other current liabilities (3.6 ) Debt (34.6 ) Deferred tax - net (59.4 ) Other long-term liabilities (12.7 ) Total purchase price $ 802.6 As of March 31, 2015, the purchase price allocation for the acquisition was final. Goodwill was calculated as the excess of the consideration transferred over the net assets recognized and represents the estimated future economic benefits arising from other assets acquired that could not be individually identified and separately recognized. The factors contributing to the recognition of goodwill were based on several strategic and synergistic benefits that are expected to be realized from the Stream acquisition. The benefits include an enhanced global footprint and expanded language capabilities. None of the goodwill is expected to be deductible for income tax purposes and goodwill was entirely allocated to the Customer Management - Agent Services reporting unit for purposes of the evaluation for any future goodwill impairment. Intangible Assets Identified The following details the total intangible assets identified: Intangible asset type Value Life (years) Customer relationship $ 352.0 17 Trade name 17.0 4 Favorable lease contract 1.4 1 - 7 Total $ 370.4 The fair value of the customer relationship asset was determined using the income approach through an excess earnings analysis, with projected earnings discounted at a rate of 11.0% . The customer relationship intangible asset represents relationships between Stream and its customers. Convergys applied the income approach through a relief-from-royalty analysis to determine the fair value of the Stream trade name asset. The determination of the useful lives was based upon consideration of market participant assumptions and transaction specific factors. Impact on Operating Results The results of Stream’s operations have been included in Convergys’ Consolidated Financial Statements since the March 3, 2014 date of acquisition. The following table provides revenue and results of operations from the acquired Stream business included in Convergys’ 2014 results: Three Months Ended Twelve Months Ended December 31, 2014 December 31, 2014 Revenues $ 253.3 $ 834.8 Income before income taxes $ 9.2 $ 11.2 The following unaudited pro forma information assumes the acquisition of Stream occurred at the beginning of the respective periods presented.

As described more fully in Note 7, 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 conversion price of $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 December 31, 2015 , the implied conversion price for the 2029 Convertible Debentures was $11.50 per share, or eighty-six and ninety-five hundredths shares per one thousand dollars in principal amount of debentures. There were 5.8 , 4.5 and 4.7 dilutive shares related to the 2029 Convertible Debentures for 2015 , 2014 and 2013 , respectively. Shareholders’ Equity The Company repurchased 3.1 of its common shares during the year ended December 31, 2015 at an average price of $23.30 per share for a total of $72.5 . Based upon the timing of transactions, $0.9 of the shares repurchased had not settled as of December 31, 2015 . There were 2.3 shares repurchased during the year ended December 31, 2014 . Below is a summary of the Company’s share repurchases during 2015 , 2014 and 2013 : Shares Cost 2015 3.1 $ 72.5 2014 2.3 $ 46.3 2013 6.7 $ 119.0 At December 31, 2015 , the Company had the authority to repurchase an additional $214.7 of outstanding common shares pursuant to share repurchase authorizations approved by the Company’s Board of Directors, including approval by the Company’s Board of Directors in August 2015 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. Preferred Shares The Company is authorized to issue up to 4.0 voting preferred shares, and 1.0 nonvoting preferred shares. At December 31, 2015 and 2014 , there were no preferred shares issued or outstanding.

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 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 December 31, 2015 and 2014 , all goodwill was held by the Customer Management - Agent Services reporting unit. The most recent annual impairment test performed as of October 1, 2015 , 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, 2015 annual impairment test, no indications of an impairment were identified. Below is a progression of goodwill for 2015 and 2014 : Balance at December 31, 2013 $ 589.4 Stream acquisition 277.5 Foreign currency and other (16.2 ) Balance at December 31, 2014 $ 850.7 Stream acquisition (1.0 ) Foreign currency and other (19.4 ) Balance at December 31, 2015 $ 830.3 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 December 31, 2015 and 2014 , the Company’s other intangible assets consisted of the following: 2015 Gross Carrying Amount Accumulated Amortization Net Software (classified within Property and equipment, net) $ 41.3 $ (38.5 ) $ 2.8 Trademarks 26.0 (17.3 ) 8.7 Customer relationships and other intangibles 458.1 (148.7 ) 309.4 Total $ 525.4 $ (204.5 ) $ 320.9 2014 Software (classified within Property and equipment, net) $ 41.3 $ (34.8 ) $ 6.5 Trademarks 26.5 (13.4 ) 13.1 Customer relationships and other intangibles 468.7 (126.6 ) 342.1 Total $ 536.5 $ (174.8 ) $ 361.7 The intangible assets are being amortized using the following amortizable lives: 8 to 10 years for software, 4 years for trademarks and 1 to 17 years for customer relationships and other intangibles. The remaining weighted average depreciation period for software is approximately 1.0 year. The remaining weighted average amortization period for customer relationships and other intangibles is approximately 14.0 years. Amortization of software is included within depreciation expense as the underlying assets are classified within property and equipment. Amortization expense for intangibles was $27.0 , $24.7 and $5.3 for the years ended December 31, 2015 , 2014 and 2013 , respectively and the related estimated expense for the five subsequent fiscal years is as follows: For the year ended 2016 $ 26.5 For the year ended 2017 26.4 For the year ended 2018 22.9 For the year ended 2019 22.2 For the year ended 2020 21.5 Thereafter 198.6

In connection with entering into the Credit Agreement, Convergys terminated its $300.0 Four-Year Competitive Advance and Revolving Credit Facility Agreement dated March 11, 2011. The Credit Agreement consists of unsecured term loans (the Term Loan) in the initial aggregate amount of $350.0 , and an unsecured revolving credit facility (the Revolving Credit Facility) in the amount of $300.0 . The Company recorded the initial carrying amount of the Term Loan at $344.9 , reflecting a discount of $5.1 resulting from fees paid directly to the lenders at issuance. The discount will be amortized over the life of the Term Loan using the effective interest rate method ( 2.6% as of December 31, 2015), and is included in interest expense in the Consolidated Statements of Income. The Term Loan and the Revolving Credit Facility mature on March 3, 2019 , unless extended pursuant to the terms of the Credit Agreement. Outstanding amounts bear interest at the applicable rate described in the Credit Agreement. During 2015 and 2014, the Company made voluntary Term Loan principal payments of $50.0 and $85.0 , respectively. The next required principal payment is due March 3, 2019. While amounts borrowed and repaid under the Revolving Credit Facility may be re-borrowed, amounts repaid under the Term Loan may not be borrowed again under the Credit Agreement. Total borrowing capacity remaining under the Revolving Credit Facility was $300.0 , with $215.0 outstanding principal on the Term Loan, as of December 31, 2015. 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’s interest coverage ratio cannot be less than 4.00 to 1.00 as determined as of the most recently ended period of four consecutive fiscal quarters. The Company’s net leverage ratio cannot be greater than 3.00 to 1.00 at anytime on or after the effective date of the Credit Agreement. In the event of default, the lenders may terminate the commitments and declare the amounts outstanding, and all accrued interest, fees and other obligations, immediately due and payable. The Company was in compliance with all covenants at December 31, 2015 . 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 ( 4.875% 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 is recognized as the fair value of a similar instrument that does 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 does 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 December 31, 2015 or 2014. 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 $14.95 ) 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 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 December 31, 2015, the implied conversion price for the 2029 Convertible Debentures was $11.50 per share, or eighty-six and ninety-five 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 December 31, 2015 and December 31, 2014, 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 $14.95 , 130% of the conversion price of the 2029 Convertible Debentures at December 31, 2015, for at least 20 of the last 30 consecutive trading days ending on December 31, 2015). As a result, the equity component of the 2029 Convertible Debentures equal to $62.9 (the difference between the par value and carrying value of the 2029 Convertible Debentures at December 30, 2015) has been classified as temporary equity within the December 31, 2015 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 December 31, 2015, the fair value of the $125.0 aggregate principal amount of the Company’s 2029 Convertible Debentures is $286.1 . Asset Securitization Facility During January 2014, the Company extended the terms of an asset securitization facility collateralized by accounts receivable of certain of the Company’s subsidiaries, with a purchase limit of $150.0 expiring in January 2017 . During June 2015, the Company amended the asset securitization facility to include the receivables of certain of the Company’s Stream subsidiaries. The asset securitization program is conducted through Convergys Funding Inc., a wholly-owned bankruptcy remote subsidiary of the Company. During March 2015, the Company entered into an amendment to the asset securitization facility to adjust the maximum Debt-to EBITDA ratio permitted under the terms of the facility. As of December 31, 2015 and 2014, Convergys had drawn $60.0 and $40.0 , respectively, in available funding from qualified receivables. Amounts drawn under this facility have been classified as long-term debt within the Consolidated Balance Sheets. At December 31, 2015 , future minimum payments of the Company’s debt and capital lease arrangements (exclusive of any debt discounts) are as follows: 2016 $ 3.4 2017 61.8 2018 0.7 2019 215.5 2020 0.4 Thereafter 125.0 Total $ 406.8

Defined Benefit Pension Plans and Defined Benefit Postretirement Plans Disclosure [Abstract]
Employee Benefit Plans	EMPLOYEE BENEFIT PLANS Pensions The Company sponsors a frozen defined benefit pension plan, which includes both a qualified and non-qualified portion, for all eligible employees (the cash balance plan) in the U.S and unfunded defined benefit plans for certain eligible employees in the Philippines, Malaysia and France (together with the cash balance plan, the defined benefit plans).The pension benefit formula for the cash balance plan is determined by a combination of compensation and age-based credits and annual guaranteed interest credits. The qualified portion of the cash balance plan has been funded through contributions made to a trust fund in accordance with the Pension Protection Act of 2006. Based on the funded status of the cash balance plan and mandatory legislative requirements under the Pension Protection Act, beginning April 29, 2009, lump sum payments from the cash balance plan were partially restricted. In December 2012, the Company made contributions to the plan to satisfy funding requirements for 2013. Subsequently, on January 18, 2013, the Company received an Adjusted Funding Target Attainment Percentage (AFTAP) certification stating that the 2013 AFTAP for the defined benefit plan is 80 percent or higher. Accordingly, limitations on accelerated benefit distributions and benefit accruals no longer apply as of the date of the certification. The Company’s measurement date for all plans is December 31. The projected unit credit cost method is used for determining the unfunded executive pension cost for financial reporting purposes. The plan assumptions are evaluated annually and are updated as necessary. Components of pension cost and other amounts recognized in other comprehensive income for the Company’s defined benefit plans are as follows: Year Ended December 31, 2015 2014 2013 Service cost $ 7.5 $ 7.1 $ 5.0 Interest cost on projected benefit obligation 10.5 10.5 10.8 Expected return on plan assets (10.2 ) (9.2 ) (10.0 ) Amortization and deferrals—net 10.4 8.1 11.6 Settlement charge — 4.6 13.4 Total pension cost $ 18.2 $ 21.1 $ 30.8 Other comprehensive income (loss) $ 14.5 $ (23.4 ) $ 46.9 During 2014 and 2013, the Company recognized non-cash pension settlement charges of $4.6 and $13.4 , respectively, resulting from a high volume of lump sum distributions. No such charge was recognized during 2015. The reconciliation of the defined benefit plans’ projected benefit obligation and the fair value of plan assets for the years ended December 31, 2015 and 2014 are as follows: At December 31, 2015 2014 Change in benefit obligation: Benefit obligation at beginning of year $ 259.6 $ 228.1 Service cost 7.5 7.1 Interest cost 10.5 10.5 Assumed obligation from Stream — 2.6 Actuarial loss (gain) (16.2 ) 35.2 Benefits paid (18.5 ) (23.9 ) Benefit obligation at end of year $ 242.9 $ 259.6 Change in plan assets: Fair value of plan assets at beginning of year $ 150.5 $ 162.9 Actual return on plan assets (0.4 ) 7.9 Employer contribution 25.6 3.6 Benefits paid (18.5 ) (23.9 ) Fair value of plan assets at end of year $ 157.2 $ 150.5 Funded status $ (85.7 ) $ (109.1 ) Amounts recognized in the Consolidated Balance Sheets consisted of: Current liability $ (6.4 ) $ (5.6 ) Non-current liability $ (79.3 ) $ (103.5 ) Accumulated other comprehensive loss $ (64.4 ) $ (78.9 ) Accumulated other comprehensive loss at December 31, 2015 and 2014 includes unrecognized actuarial losses of $64.4 ( $39.5 net of tax) and $78.9 ( $47.2 net of tax), respectively. The actuarial loss included in accumulated other comprehensive loss that is expected to be recognized in net periodic pension cost during 2016 is $6.6 . The accumulated benefit obligation for the defined benefit plans was $242.9 and $259.6 at December 31, 2015 and 2014 , respectively. Estimated future benefit payments from the defined benefit plans are as follows: 2016 $ 17.0 2017 34.0 2018 35.1 2019 36.1 2020 36.1 2021 - 2025 106.2 Total $ 264.5 The Company also sponsors a non-qualified, unfunded executive deferred compensation plan (the EDCP), which permits eligible participants, including executive officers, to defer receipt of certain income. The EDCP was frozen as of December 31, 2011 and reinstated, effective January 1, 2014. The Company matches up to 100% of the first 3% of a participant’s deferred amounts and 50% of a participant’s next 2% of deferred amounts. The Company match under the EDCP is reduced by the Company match eligible to be received under the Company’s Retirement and Savings Plan. Benefits for the EDCP are based on employee deferrals, matching contributions and investment earnings on participant accounts. As further described in Note 12, in December 2011, the Company made investments in certain securities which are held in a grantor trust for the benefit of participants of the executive deferred compensation plan. This investment was made in securities reflecting the hypothetical investment balances of plan participants. Components of pension cost and other amounts recognized in other comprehensive loss for the EDCP are as follows: Year Ended December 31, 2015 2014 2013 Service cost $ 1.5 $ 1.3 $ — Interest cost on projected benefit obligation 0.4 0.5 0.4 Amortization and deferrals—net — — 0.2 Settlement gain — — (0.3 ) Total pension cost $ 1.9 $ 1.8 $ 0.3 Other comprehensive loss $ (0.6 ) $ (0.8 ) $ (1.0 ) The reconciliation of the EDCP projected benefit obligation for the years ended December 31, 2015 and 2014 is as follows: At December 31, 2015 2014 Change in benefit obligation: Benefit obligation at beginning of year $ 14.4 $ 14.2 Service cost 1.5 1.3 Interest cost 0.4 0.5 Actuarial loss (0.6 ) 0.8 Benefits paid (2.0 ) (2.4 ) Benefit obligation at end of year $ 13.7 $ 14.4 Funded status $ (13.7 ) $ (14.4 ) Amounts recognized in the Consolidated Balance Sheets consisted of: Current liability $ (2.3 ) $ (2.3 ) Non-current liability $ (11.4 ) $ (12.1 ) Accumulated other comprehensive income (loss) $ 1.1 $ (0.5 ) Accumulated other comprehensive loss at December 31, 2015 and 2014 includes unrecognized actuarial gains of $1.1 ( $0.7 net of tax), and $0.5 ( $0.3 net of tax). The accumulated benefit obligation for the EDCP was $13.7 and $14.4 at December 31, 2015 and 2014 , respectively. There is no prior service cost expected to be recognized in net periodic pension cost during the year ending December 31, 2016 . Estimated future benefit payments from the EDCP are as follows: 2016 $ 2.3 2017 3.3 2018 1.7 2019 1.7 2020 2.2 2021 - 2025 9.5 Total $ 20.7 The following weighted-average rates were used in determining the benefit obligations at December 31: 2015 2014 Discount rate—projected benefit obligation 3.61% - 5.56% 1.75% - 4.90% Future compensation growth rate 2.50% - 4.50% 2.87% - 4.00% Expected long-term rate of return on plan assets 6.75% - 7.00% 6.75% - 7.00% The following weighted-average rates were used in determining the pension cost for all years ended December 31: 2015 2014 2013 Discount rate—projected benefit obligation 3.61% - 5.56% 1.75% - 4.90% 3.00% - 4.61% Future compensation growth rate 2.50% - 4.50% 2.50% - 4.00% 4.00% Expected long-term rate of return on plan assets 6.75% - 7.00% 6.75% - 7.00% 6.75% - 8.00% The range of discount rates utilized in determining the pension cost and projected benefit obligation of the Company’s defined benefit plans reflects a lower prevalent rate applicable to the frozen cash balance plan for eligible employees in U.S. and a higher applicable rate for the unfunded defined benefit plan for certain eligible employees in the Philippines, France and Malaysia. The plans outside the U.S. represented approximately 16.3% and 15.4% of the Company’s total projected benefit obligation for all plans as of December 31, 2015 and 2014, respectively. Change in Applying Discount Rate to Measure Benefit Costs As of December 31, 2015, Convergys changed the method used to estimate the service and interest cost components of net periodic benefit cost for pension and other postretirement benefits. This change in methodology is expected to result in a decrease in the service and interest cost components for pension and other postretirement benefit costs beginning in the first quarter of 2016. Convergys historically estimated these service and interest cost components utilizing a single weighted-average discount rate derived from the yield curve used to measure the benefit obligation at the beginning of the period. Beginning in 2016, the Company has elected to utilize a full yield curve approach in the determination of these components by applying the specific spot rates along the yield curve used in the determination of the benefit obligation to the relevant projected cash flows. Convergys elected to make this change to provide a more precise measurement of service and interest costs by improving the correlation between projected benefit cash flows to the corresponding spot yield curve rates. This change does not affect the measurement of Convergys’ total benefit obligations at December 31, 2015 or net periodic pension cost recognized in 2015. Convergys has accounted for this change as a change in accounting estimate and accordingly has accounted for it prospectively. The impact of this discount rate change compared to the previous method is expected to decrease estimated pension and other postretirement benefits service and interest cost by approximately $2.4 for 2016, or approximately $0.6 quarterly, with substantially all of the decrease attributable to interest cost. These reductions in service and interest cost will be completely offset within the actuarial gain or loss caption when the plans are remeasured, which typically occurs during the fourth quarter. As of December 31, 2015 and 2014 , plan assets for the cash balance plan consisted of common/collective trusts (of which approximately 65% are invested in equity backed funds and approximately 35% are invested in funds invested in fixed income instruments, including cash) and a private equity fund. At December 31, 2015 , the Company’s targeted allocation was 65% equity and 35% fixed income. As of December 31, 2015 , plan assets for the cash balance plan did not include any of the Company’s common shares, compared to $3.7 of the Company’s common shares included in plan assets at December 31, 2014 . The investment objectives for the plan assets are to generate returns that will enable the plan to meet its future obligations. The Company’s expected long-term rate of return was determined based on the asset mix of the plan, projected returns, past performance and other factors. The Company contributed $20.0 and $10.0 in 2015 and 2014 , respectively, to fund its cash balance plan, which satisfies its ERISA funding requirements through 2016. No plan assets are expected to be returned to the Company during 2016 . The following table sets forth by level, within the fair value hierarchy, the cash balance plan’s assets at fair value as of December 31, 2015 and 2014 : Investments December 31, 2015 Quoted Prices In Active Markets for Identical Assets (Level 1) Significant Other Observable Inputs (Level 2) Significant Unobservable Inputs (Level 3) Common/collective trusts: Fixed income $ 54.0 $ — $ 54.0 $ — U.S. large cap 61.8 — 61.8 — U.S. small cap 10.6 — 10.6 — International equity 28.0 — 28.0 — Limited partnership 2.8 — — 2.8 Total investments $ 157.2 $ — $ 154.4 $ 2.8 Investments December 31, 2014 Quoted Prices In Active Markets for Identical Assets (Level 1) Significant Other Observable Inputs (Level 2) Significant Unobservable Inputs (Level 3) Common/collective trusts: Fixed income $ 52.6 $ — $ 52.6 $ — U.S. large cap 55.1 — 55.1 — U.S. small cap 10.1 — 10.1 — International equity 25.6 — 25.6 — Convergys common shares 3.7 3.7 — — Limited partnership 3.4 — — 3.4 Total investments $ 150.5 $ 3.7 $ 143.4 $ 3.4 There were no transfers between the three levels of the fair value hierarchy during the years ended December 31, 2015 and 2014 . For additional information on the fair value hierarchy, see Note 13. The Company’s cash balance plan holds level 2 investments in common/collective trust funds that are public investment vehicles valued using a net asset value (NAV) provided by the manager of each fund. The NAV is based on the underlying net assets owned by the fund, divided by the number of shares outstanding. The NAV’s unit price is quoted on a private market that may not be active. However, the NAV is based on the fair value of the underlying securities within the fund, which are traded on an active market, and valued at the closing price reported on the active market on which those individual securities are traded. The significant investment strategies of the funds are as described in the financial statements provided by each fund. There are no restrictions on redemptions from these funds. The Company’s cash balance plan holds Level 3 investments within equity funds that primarily invest in domestic early stage capital funds. The fair value of these investments is based on the net asset value per share of the fund. The cash balance plan has approximately $0.2 in future funding requirements associated with this investment. The methods described above may produce a fair value calculation that may not be indicative of net realizable value or reflective of future fair values. Furthermore, while the Company believes its valuation methodologies are appropriate and consistent with other market participants, the use of different methodologies or assumptions to determine the fair value of certain financial instruments could result in a different fair value measurement. The following table provides a reconciliation of the beginning and ending balances for the Level 3 assets: Year Ended December 31 2015 2014 Balance, beginning of year $ 3.4 $ 3.5 Unrealized losses relating to instruments still held at the reporting date (0.6 ) (0.1 ) Balance, end of year $ 2.8 $ 3.4 Savings Plans The Company sponsors a defined contribution plan covering substantially all U.S. employees. The Company matches a portion of employee contributions to the plan. In 2014, the Company’s matching contribution changed from 100% of the first 3% to 100% of the first 3% and 50% of the next 2% of eligible compensation contributed by the participant. As a result, total Company contributions to the defined contribution plan were $7.4 in 2015 compared to $6.5 and $5.5 for 2014 and 2013 , respectively. Plan assets for this plan included 0.9 ( $23.6 ) and 1.1 ( $21.8 ) of the Company’s common shares at December 31, 2015 and 2014 , respectively. Employee Postretirement Benefits Other Than Pensions The Company sponsors postretirement health and life insurance plans for certain eligible employees. The plan provides eligible employees and retirees with the opportunity to direct an amount of their compensation or pension benefits to cover medical, dental and life insurance programs of their choice for their benefit and the benefit of their dependents. The plan covers both active and retired eligible employees of the Company and its subsidiaries. Employees’ eligibility to participate in the plan is based upon their date of hire. The Company funds life insurance benefits of certain retirees through a Voluntary Employee Benefit Association (VEBA) trust. Contributions to the plan consist of (1) compensation or pension benefit deductions that the participant directs the Company, which is also the Plan Sponsor, to deposit into the plan on their behalf based on the coverage the participant has elected under the plan, and (2) amounts the Company pays to the plan that are in excess of the participant-directed deductions. Contributions to the VEBA are subject to Internal Revenue Service (IRS) limitations developed using the aggregate cost method. At December 31, 2006, the Company eliminated the postretirement life insurance plan benefits for non-retirement eligible employees. The Company’s postretirement benefit plan benefit was $0.8 , $1.6 , and $4.3 for 2015 , 2014 and 2013 , respectively. The amounts included within accumulated other comprehensive loss related to these benefits were $2.1 and $2.8 at December 31, 2015 and 2014 , respectively. Components of other post-employment benefit plan cost and other amounts recognized in other comprehensive (loss) income for the postretirement health and life insurance plans are as follows: 2015 2014 2013 Interest cost on projected benefit obligation $ 0.2 $ 0.2 $ 0.2 Expected return on plan assets (0.3 ) (0.3 ) (0.4 ) Amortization and deferrals—net (0.7 ) (1.0 ) (3.8 ) Curtailment benefit — (0.5 ) (0.3 ) Total other benefit $ (0.8 ) $ (1.6 ) $ (4.3 ) Other comprehensive loss $ (0.7 ) $ (1.8 ) $ (2.0 ) The reconciliation of the postretirement health and life insurance plans’ projected benefit obligation and the fair value of plan assets for the years ended December 31, 2015 and 2014 are as follows: At December 31, 2015 2014 Change in benefit obligation: Benefit obligation at beginning of year $ 4.5 $ 4.5 Interest cost 0.2 0.2 Actuarial (gain) loss (0.2 ) 0.1 Benefits paid (0.3 ) (0.3 ) Benefit obligation at end of year $ 4.2 $ 4.5 Change in plan assets: Fair value of plan assets at beginning of year $ 4.2 $ 4.9 Actual return on plan assets 0.1 0.1 Employer contribution (0.6 ) (0.5 ) Benefits paid (0.3 ) (0.3 ) Fair value of plan assets at end of year $ 3.4 $ 4.2 Funded status $ (0.8 ) $ (0.3 ) Amounts recognized in the Consolidated Balance Sheets consisted of: Non-current assets $ — $ 0.3 Current liability $ (0.1 ) $ (0.1 ) Non-current liability $ (0.7 ) $ (0.5 ) Accumulated other comprehensive income $ 2.1 $ 2.8 Estimated future benefit payments from the postretirement health and life insurance plans are as follows: 2016 $ 0.3 2017 0.5 2018 0.5 2019 0.5 2020 0.5 2021 - 2025 1.3 Total $ 3.6 Plan assets for the postretirement health and life insurance plans of $3.4 and $4.2 at December 31, 2015 and 2014 , respectively, are comprised of money market accounts, a Level 1 measure. The Company expects to make $0.1 in contributions in 2016 to fund its post retirement health and life insurance plans. No plan assets are expected to be returned to the Company during 2016 .

Share-based Compensation, Allocation and Classification in Financial Statements [Abstract]
Disclosure of Compensation Related Costs, Share-based Payments [Text Block]	STOCK-BASED COMPENSATION PLANS At December 31, 2015 , the Company had 38.0 common shares that were authorized for issuance under the Convergys Corporation 1998 Long-Term Incentive Plan (Convergys LTIP), as amended on January 28, 2011. The Company granted stock options in 2012 and 2011 with exercise prices that were no less than the market value of the Company’s common shares at the grant date and have a ten-year term and vesting terms of two to three years. The Company also grants restricted stock units to certain employees and directors. The restricted stock units do not possess voting rights and consist of both time-related and performance-related units. The restrictions for the time-related restricted stock units generally lapse one to three years after the grant date. The performance-related units vest upon the Company’s satisfaction of certain financial targets. Performance-related units that have not vested by the end of three years from the grant date (i.e., the performance conditions for vesting of those units have not been met within that period) are forfeited. The following table shows certain information as of December 31, 2015 , with respect to compensation plans under which common shares are authorized for issuance: Shares (in millions) Number of Common Shares to be Issued Upon Exercise Weighted Average Exercise Price Common Shares Available for Future Issuance Equity compensation plans approved by shareholders Stock options 0.5 $ 13.33 — Restricted stock units 2.2 — — 2.7 $ 13.33 7.4 The Company’s operating results reflect stock-based compensation expense of $16.9 , $10.2 and $13.4 for 2015 , 2014 and 2013 , respectively. Expense in 2015 and 2014 included $1.2 and $1.8 , respectively, related to awards classified as liabilities that will ultimately settle in cash. Restricted Stock Units Time-based Restricted Stock Units During the years ended December 31, 2015 , 2014 and 2013 , the Company granted 0.7 , 0.7 and 0.6 shares, respectively, of time-based restricted stock units. The weighted average grant date fair values of these grants were $22.41 , $20.55 and $16.35 , 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. The total compensation cost related to non-vested time-based restricted stock units not yet recognized as of December 31, 2015 was approximately $15.1 , which is expected to be recognized over a weighted average period of 1.0 year. Changes to non-vested time-based restricted stock units for the years ended December 31, 2015 and 2014 were as follows: Shares (in millions) Number of Shares Weighted Average Fair Value at Date of Grant Non-vested at December 31, 2012 1.6 $ 13.04 Granted 0.6 16.35 Vested (0.7 ) 12.75 Forfeited (0.1 ) 14.09 Non-vested at December 31, 2013 1.4 14.62 Granted 0.7 20.55 Vested (0.6 ) 14.33 Forfeited (0.2 ) 18.85 Non-vested at December 31, 2014 1.3 17.66 Granted 0.7 22.41 Vested (0.5 ) 16.53 Forfeited (0.2 ) 20.78 Non-vested at December 31, 2015 1.3 $ 20.20 Performance-based Restricted Stock Units During the years ended December 31, 2015 , 2014 and 2013, the Company granted 0.4 , 0.3 and 0.4 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 performance minimum threshold level. At December 31, 2015 , the targets for the third year of the 2014 grants and the second and third years of the 2015 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 2015, the Company established and communicated to participants the final key terms of the 2013 grants, resulting in grants for accounting purposes with a grant date fair value of $21.84 per share. The total compensation cost related to the 2013 non-vested performance-based restricted stock units not yet recognized as of December 31, 2015 was approximately $0.1 , which is expected to be recognized ratably over the remaining vesting period ending in February 2016. Changes to non-vested performance-based restricted stock units for the years ended December 31, 2015, 2014 and 2013 were as follows: Shares (in millions) Number of Shares Weighted Average Fair Value at Date of Grant Non-vested at December 31, 2012 1.0 $ 12.69 Granted 0.1 16.34 Vested (0.8 ) 13.32 Forfeited — — Non-vested at December 31, 2013 0.3 12.90 Granted — — Vested (0.3 ) 12.90 Forfeited — — Non-vested at December 31, 2014 — — Granted 0.3 21.84 Vested — — Forfeited — — Non-vested at December 31, 2015 0.3 $ 21.84 The aggregate intrinsic value of non-vested restricted stock units was $41.1 at December 31, 2015 . Stock Options Presented below is a summary of Company stock option activity: Shares (in millions) Shares Weighted Average Exercise Price Options outstanding at January 1, 2013 1.2 $ 12.91 Options exercisable at January 1, 2013 0.3 11.86 Granted — — Exercised (0.3 ) 12.24 Forfeited (0.1 ) 13.31 Options outstanding at December 31, 2013 0.8 $ 13.11 Options exercisable at December 31, 2013 0.2 $ 13.14 Granted — — Exercised (0.1 ) 12.38 Forfeited — — Options outstanding at December 31, 2014 0.7 $ 13.24 Options exercisable at December 31, 2014 0.5 $ 13.41 Granted — — Exercised (0.2 ) 13.09 Forfeited — — Options outstanding at December 31, 2015 0.5 $ 13.33 Options exercisable at December 31, 2015 0.5 $ 13.33 Approximately one-half of the stock options granted during 2012 vested in two years and the remaining vested in three years. The Company used the Black-Scholes option pricing model to calculate the fair value of stock options granted. For the 2012 grants, the weighted average fair value at grant date of $3.43 per option granted included assumptions of a strike price of $12.79 , a 30.74% implied volatility, an expected term of 4.5 years, a risk-free rate of 0.76% , and a dividend yield of 0.00% . These 2012 option grants resulted in stock compensation expense of less than $0.1 , $0.2 and $0.6 in 2015, 2014 and 2013, respectively. Expected volatility is based on the unbiased standard deviation of the Company’s common shares over the option term. The expected life of the options represents the period of time that the Company expects the options granted to be outstanding. The risk-free rate is based on the U.S. Treasury yield curve in effect at the time of the grant of the option for the expected term of the instrument. The dividend yield reflects an estimate of dividend payouts over the term of the award. As of December 31, 2015, all outstanding stock options are fully vested and the related expense has been fully recognized. The weighted average grant date fair value per share for the outstanding and exercisable options at December 31, 2015 was $3.78 and $3.74 , respectively. The following table summarizes the status of the Company stock options outstanding and exercisable at December 31, 2015 : Shares (in millions) Options Outstanding Options Exercisable Range of Exercise Prices Shares Weighted Average Remaining Contractual Life (in years) Weighted Average Exercise Price Shares Weighted Average Remaining Contractual Life (in years) Weighted Average Exercise Price $11.56 to $21.81 0.5 5.6 13.33 0.5 5.6 13.33 Total 0.5 5.6 $ 13.33 0.5 5.6 $ 13.33 The aggregate intrinsic value of stock options exercised was $2.7 in 2015 , $1.1 in 2014 and $1.3 in 2013 . The actual tax benefit realized from the exercised stock options was $0.6 in 2015 , $0.2 in 2014 and $0.3 in 2013 . As of December 31, 2015 , the aggregate intrinsic value was $5.3 for both stock options outstanding and exercisable. Intrinsic value represents the Company’s closing price on the last trading day of the year in excess of the weighted average exercise price for those tranches of options with a weighted average exercise price less than the closing price multiplied by the number of options outstanding or exercisable.

Commitments And Contingencies	COMMITMENTS AND CONTINGENCIES Commitments The Company leases certain facilities and equipment used in its operations. Total rent expense was $129.3 , $125.2 and $81.0 in 2015 , 2014 and 2013 , respectively. At December 31, 2015 , the total minimum rental commitments under non-cancelable operating leases are as follows: 2016 $ 97.9 2017 75.8 2018 56.4 2019 36.4 2020 25.1 Thereafter 71.3 Total $ 362.9 At December 31, 2015 , the Company had outstanding letters of credit and bond obligations of $26.0 related to performance guarantees, of which $18.2 is set to expire by the end of 2016, $7.6 is set to expire within one to three years and $0.2 is set to expire after three years. At December 31, 2015 , the Company had an outstanding performance bond obligation of $30.0 related to a performance guarantee for the Company’s former HR Management line of business which was sold in 2010 to NorthgateArinso. Subsequent to completion of the sale of the HR Management business, the Company continues to be responsible for this bond obligation. As part of the gain on disposition, the Company recognized a liability equal to the present value of probability weighted cash flows of potential outcomes, a Level 3 fair value measurement. Although the buyer is obligated to indemnify the Company for any and all losses, costs, liabilities and expenses incurred related to these performance bonds, as of December 31, 2015 , the Company maintained a liability of $0.2 for these obligations. The Company’s guarantee for this bond obligation expires in August 2016. The Company also has future purchase commitments with telecommunication and transportation providers of $54.1 at December 31, 2015 . 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. In November 2011, one of the Company’s call center clients, Hyundai Motor America (Hyundai), tendered a contractual indemnity claim to Convergys Customer Management Group Inc., a subsidiary of the Company, relating to a putative class action captioned Brandon Wheelock, individually and on behalf of a class and subclass of similarly situated individuals, v. Hyundai Motor America, Orange County Superior Court, California, Case No. 30-2011-00522293-CU-BT-CJC. The lawsuit alleged that Hyundai violated California’s telephone recording laws by recording telephone calls with customer service representatives without providing a disclosure that the calls might be recorded. An amended settlement agreement was executed by the plaintiff, Hyundai and Convergys Customer Management Group Inc., and received final approval from the Court during the fourth quarter of 2015. The Company’s liability with respect to the proposed settlement was fully accrued at December 31, 2015, and did not have a material impact on the Company’s liquidity, results of operations or financial condition with final payment made during January 2016.

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 in various countries such as the Philippines, India, Canada, China, Malaysia, Egypt, Costa Rica, Colombia, Dominican Republic, El Salvador, Nicaragua and Honduras. 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. Additionally, we have certain client contracts that are priced in Australian dollars, for which a substantial portion of the costs to deliver services are denominated in other currencies. 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 37,623.0 at a fixed price of $823.4 at various dates through December 2018 , INR 10,932.0 at a fixed price of $156.2 at various dates through December 2018 , CAD 40.7 at a fixed price of $32.3 at various dates through April 2018 and COP 10,000.0 at a fixed price of $3.2 at various dates through May 2016 , and to sell a total of AUD 36.0 at a fixed price of 25.8 at various dates through December 2016 . These instruments mature within the next 36 months and had a notional value of $1,040.8 at December 31, 2015 and $1,131.7 at December 31, 2014 . 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: At December 31, 2015 2014 Forward exchange contracts and options designated as hedging instruments: Included within other current assets $ 1.2 $ 1.7 Included within other non-current assets 0.8 1.3 Included within other current liabilities 29.7 21.4 Included within other long-term liabilities 14.7 11.3 The Company recorded a deferred tax benefit of $16.2 and $11.3 related to these derivatives at December 31, 2015 and 2014 , respectively. A total of $26.1 and $18.3 of deferred losses, net of tax, related to these cash flow hedges at December 31, 2015 and 2014 , respectively, were included in accumulated other comprehensive loss (OCL). As of December 31, 2015 , deferred losses of $28.4 ( $17.5 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 2015 and 2014 , respectively: 2015 : 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 $ (37.9 ) $ (25.2 ) Cost of providing services and products sold and Selling, general and administrative 2014 : 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 $ (7.5 ) $ (14.3 ) 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 years ended December 31, 2015 and 2014 . During 2015 , 2014 and 2013 , the Company recorded net losses of $25.2 , $14.3 and $2.1 , respectively, related to the settlement of forward contracts and options that were designated as cash flow hedges. 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 year ended December 31, 2015 , a gain of $0.3 was recognized related to changes in fair value of these derivative instruments not designated as hedges, compared to a gain of $2.0 in the same period in 2014 . 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 December 31, 2015 , was a $0.1 receivable. The aggregate fair value of all derivative instruments in a liability position at December 31, 2015 was $44.4 for which the Company has no posted collateral. Short-term Investments As of December 31, 2015 and 2014 , the Company held investment securities with a fair value of $12.2 and $13.0 , 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, common shares of the Company and money market accounts. These securities are carried at fair value, with gains and losses, both realized and unrealized, reported in other income (expense), 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 income (expense), 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 December 31, 2015 and 2014 , 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 December 31, 2015 and 2014 . The derivative assets and liabilities measured at fair value on a recurring basis as of December 31, 2015 and 2014 were as follows: December 31, 2015 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) $ 2.1 $ — $ 2.1 $ — Foreign currency forward contracts (liability position) $ 44.4 $ — $ 44.4 $ — December 31, 2014 Quoted Prices Significant Significant Derivatives: Foreign currency forward contracts (asset position) $ 3.3 $ — $ 3.3 $ — Foreign currency forward contracts (liability position) $ 32.7 $ — $ 32.7 $ — The Company also had investment securities held in a grantor trust for the benefit of participants of the EDCP measured at fair value at December 31, 2015 and December 31, 2014 . 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 December 31, 2015 and 2014 . The assets measured at fair value on a recurring basis as of December 31, 2015 and 2014 were as follows: December 31, 2015 Quoted Prices In Active Markets for Identical Assets (Level 1) Significant Other Observable Inputs (Level 2) Significant Unobservable Inputs (Level 3) Investment securities: Mutual funds $ 9.7 $ 9.7 $ — $ — Convergys common stock 1.8 1.8 — — Money market accounts 0.7 0.7 — — Total $ 12.2 $ 12.2 $ — $ — December 31, 2014 Quoted Prices In Active Markets for Identical Assets (Level 1) Significant Other Observable Inputs (Level 2) Significant Unobservable Inputs (Level 3) Investment securities: Mutual funds $ 10.3 $ 10.3 $ — $ — Convergys common stock 2.1 2.1 — — Money market accounts 0.6 0.6 — — Total $ 13.0 $ 13.0 $ — $ —

Income Taxes	INCOME TAXES The Company’s provision for income taxes from continuing operations consists of the following: Year Ended December 31, 2015 2014 2013 Current: United States federal $ (21.3 ) $ 33.8 $ (3.1 ) Foreign 25.3 45.6 10.2 State and local — 1.1 1.5 Total current 4.0 80.5 8.6 Deferred: United States federal 6.0 (42.4 ) 30.7 Foreign (4.3 ) (27.5 ) 34.0 State and local 2.9 2.2 (0.8 ) Total deferred 4.6 (67.7 ) 63.9 Total $ 8.6 $ 12.8 $ 72.5 The Company’s combined pre-tax earnings from continuing operations relating to foreign subsidiaries or branches were $139.5 , $143.8 and $99.1 during 2015 , 2014 and 2013 , respectively. The following is a reconciliation of the statutory federal income tax rate with the effective tax rate from continuing operations for the tax expense in 2015 , 2014 and 2013 , respectively: Year Ended December 31, 2015 2014 2013 U.S. federal statutory rate 35.0 % 35.0 % 35.0 % Permanent differences 2.3 8.6 6.8 State and local income taxes, net of federal income tax 1.1 1.7 0.4 International rate differential, including tax holidays (21.2 ) (29.8 ) (14.0 ) Foreign valuation allowances 1.0 2.3 — Adjustments for uncertain tax positions (12.9 ) 1.2 2.3 Tax credits and other 0.6 (4.5 ) (10.4 ) Foreign repatriation, net of foreign tax credits (1.0 ) (4.6 ) 35.2 Effective rate 4.9 % 9.9 % 55.3 % The decrease in the effective income tax rate in 2015 was driven by a shift in the geographical mix of worldwide income, the expiration of statutes of limitation on previously recognized uncertain tax positions, and the favorable resolution of certain income tax audits. As of December 31, 2015, the Company had $506.6 of undistributed earnings of its foreign subsidiaries for which it has not provided for U.S. federal income taxes or foreign withholding taxes because such earnings are intended to be reinvested indefinitely. It is not practicable to determine the amount of applicable taxes that would be due if such earnings were distributed. The Company’s foreign taxes for 2015 , 2014 and 2013 included $6.3 , $3.9 and $2.5 , respectively, of benefit derived from tax holidays in the Philippines, the Dominican Republic, Costa Rica, El Salvador, Malaysia, Honduras, Nicaragua and Tunisia. This resulted in (3.6)% , (3.0)% and (1.9)% impact to the effective tax rate in 2015 , 2014 and 2013 , respectively. The tax holidays in the Philippines will expire in 2016 through 2019. The Company will apply to extend these tax holidays for additional terms of one to two years in accordance with local law. The components of deferred tax assets and liabilities are as follows: At December 31, 2015 2014 Deferred tax assets: Loss and credit carryforwards $ 91.8 $ 104.7 Pension and employee benefits 37.7 44.7 Restructuring charges 0.3 1.3 Deferred revenue 3.2 2.9 Foreign currency hedges 16.2 11.4 Intercompany payables/receivables 62.0 48.3 Other 42.4 47.9 Valuation allowances (36.2 ) (39.3 ) Total deferred tax assets 217.4 221.9 Deferred tax liabilities: Depreciation and amortization 277.4 291.4 Deferred implementation costs 0.1 0.6 Contingent debt and accrued interest 77.9 67.7 Unremitted foreign earnings 15.8 15.7 Other 7.6 7.3 Total deferred tax liabilities 378.8 382.7 Net deferred tax liabilities $ (161.4 ) $ (160.8 ) Deferred tax assets and liabilities in the preceding table, after netting by taxing jurisdiction, are in the following captions in the Consolidated Balance Sheets at December 31, 2015 and 2014 .

As of December 31, 2015 , the Company has federal, state, and foreign operating loss carryforwards of $96.1 , $673.2 and $54.4 , respectively. The federal operating loss carryforwards and state operating loss carryforwards expire between 2016 and 2035. The foreign operating loss carryforwards include $10.0 with no expiration date; the remainder will expire between 2016 and 2035. The federal and state operating loss carryforwards include losses of $91.6 and $123.6 , respectively, which were acquired in connection with business combinations. Utilization of the acquired federal and state tax loss carryforwards may be limited pursuant to Section 382 of the Internal Revenue Code of 1986. As of December 31, 2015 and 2014 , the liability for unrecognized tax benefits was $31.6 and $59.9 , respectively, including $11.8 and $24.0 of accrued interest and penalties, respectively, and is recorded in Other long-term liabilities in the Consolidated Balance Sheets. The total amount of net unrecognized tax benefits that would affect income tax expense, if ever recognized in the Consolidated Financial Statements, is $29.0 . This amount includes net interest and penalties of $10.2 . The Company’s policy is to recognize interest and penalties accrued on unrecognized tax benefits as part of income tax expense. During 2015 , the Company recognized a net benefit of $11.7 in interest and penalties, compared to net expense of $4.2 during 2014 . The net benefit of $11.7 in 2015 includes $1.7 of expense related to interest and penalties accrued on positions still outstanding as of December 31, 2015 . A reconciliation of the beginning and ending total amounts of unrecognized tax benefits (exclusive of interest and penalties) is as follows: 2015 2014 Balance at January 1 $ 37.1 $ 32.6 Additions based on tax positions related to the current year 0.2 0.4 Additions for tax positions of prior years 6.1 — Additions for tax positions of Stream on the date of acquisition — 5.9 Settlements (5.0 ) 0.5 Reductions for tax positions of prior years 0.1 (0.7 ) Lapse of statutes (16.9 ) (1.6 ) Balance at December 31 $ 21.6 $ 37.1 The liability for unrecognized tax benefits related to discontinued operations at December 31, 2015 and 2014 was $10.7 and $11.8 , respectively. The Company is currently attempting to resolve income tax audits relating to prior years in various jurisdictions. The Company has received assessments from these jurisdictions related to transfer pricing and deductibility of expenses. The Company believes that it is appropriately reserved with regard to these assessments as of December 31, 2015 . Furthermore, the Company believes that it is reasonably possible that the total amounts of unrecognized tax benefits will decrease between $4.0 and $26.0 prior to December 31, 2016 , based upon resolution of audits; however, actual developments could differ from those currently expected. The Company files income tax returns in the U.S. federal jurisdiction, and various states and foreign jurisdictions. With a few exceptions, the Company is no longer subject to examinations by tax authorities for years before 2002.

Significant Accounting Polici28

Significant Accounting Policies (Policies)	12 Months Ended
	Dec. 31, 2015
Accounting Policies [Abstract]
Consolidation [Policy Text Block]	Principles of Consolidation and Basis of Presentation The accompanying Consolidated Financial Statements have been prepared in accordance with accounting principles generally accepted in the United States of America and U.S. Securities and Exchange Commission regulations. The Consolidated Financial Statements include the accounts of the Company’s majority-owned subsidiaries. All material intercompany accounts and transactions are eliminated upon consolidation.
Reclassification, Policy [Policy Text Block]	Reclassification Certain prior year balances in the Consolidated Balance Sheet have been reclassified to conform to the current year presentation.
Use of Estimates [Policy Text Block]	Use of Estimates, Risks and Uncertainties The preparation of the Consolidated Financial Statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the amounts reported. These estimates include, but are not limited to, project completion dates, time and cost required to complete projects for purposes of revenue recognition and future revenue, expense and cash flow estimates for purposes of impairment analysis and loss contract evaluation. Actual results could differ from those estimates. The Company’s results are affected by economic, political, legislative, regulatory and legal actions. Economic conditions, such as recessionary trends, inflation, interest and monetary exchange rates, and government fiscal policies, can have a significant effect on operations. While the Company maintains reserves for anticipated liabilities and carries insurance in an amount and scope that the Company believes are appropriate, the Company could be adversely affected by civil, criminal, regulatory or administrative actions, claims or proceedings.
Foreign Currency [Policy Text Block]	Foreign Currency Translation Assets and liabilities of foreign operations are translated to U.S. dollars at year-end exchange rates. Revenues and expenses are translated at average exchange rates for the related period. Translation adjustments are accumulated and reflected as adjustments to other comprehensive (loss) income, a component of Shareholders’ Equity, and included in net earnings only upon sale or liquidation of the underlying foreign subsidiary. Gains or losses resulting from foreign exchange transactions related to balance sheet positions are recorded in the Consolidated Statements of Income within Other (expense) income, net.
Revenue Recognition [Policy Text Block]	Revenue Recognition Revenues mostly consist of fees generated from outsourced services provided to the Company’s clients. More than 95% of the Company’s revenues are derived from agent-related services. The Company typically recognizes these revenues as services are performed based on staffing hours or the number of contacts handled by service agents using contractual rates. The remaining revenues are derived from the sale of premise-based and hosted automated self-care and technology solutions and provision of professional services. Revenues from the sale of these solutions and provision of services are typically recognized as services are provided over the duration of the contract using contractual rates. These contracts are typically one year or less in duration. Revenues are recognized only when the services are performed, there is evidence of an arrangement, the Company determines that the fee is fixed and determinable and collection of the fee included in the arrangement is considered probable. When determining whether the fee is considered fixed and determinable and collection is probable, the Company considers a number of factors including the creditworthiness of the client and the contractual payment terms. If a client is not considered creditworthy, recognition of all revenue under arrangements with that client is deferred until receipt of cash. If payment terms extend beyond what is considered customary or standard in the related industry and geographic location, recognition of the revenue is deferred until the related fees become due and payable. Certain contracts have performance-related bonus provisions that require the client to pay us a bonus based upon our meeting agreed-upon service levels and performance metrics. These bonuses are recognized only after required measurement targets are met and the other criteria for recognition are satisfied.
Stock Compensation [Policy Text Block]	Stock-Based Compensation The Company accounts for stock-based payment transactions in which the Company receives employee services in exchange for equity instruments of the Company. Stock-based compensation cost for restricted stock awards and restricted stock shares and performance restricted stock units is measured based on the closing fair market value of the Company’s common shares on the date of grant. Stock-based compensation cost for stock options is estimated at the grant date based on each option’s fair-value as calculated by the Black-Scholes option-pricing model. The Company recognizes stock-based compensation cost as expense for awards other than its performance-based restricted stock units ratably on a straight-line basis over the requisite service period. The Company recognizes stock-based compensation cost associated with its performance based restricted stock units over the requisite service period if it is probable that the performance conditions will be satisfied. The Company will recognize a benefit from stock-based compensation in equity if an incremental tax benefit is realized by following the ordering provisions of the tax law. Tax benefits related to stock compensation expense are reported as financing cash flow and tax expenses are reported as operating cash flow. Further, the Company applies an estimated forfeiture rate to unvested awards when computing the stock compensation-related expenses
Income Taxes [Policy Text Block]	Income Taxes The provision for income taxes includes taxes paid, currently payable or receivable, and those deferred. Under U.S. GAAP, the Company recognizes deferred tax assets and liabilities based on the differences between the financial statement and tax basis of assets and liabilities using enacted tax rates in effect for the year in which the differences are expected to be settled or realized. The Company regularly reviews its deferred tax assets for recoverability and establishes a valuation allowance if it is more likely than not that some portion or all of a deferred tax asset will not be realized. The determination as to whether a deferred tax asset will be realized is made on a jurisdictional basis and is based on the evaluation of positive and negative evidence. This evidence includes historical pre-tax and taxable income, projected future taxable income, the expected timing of the reversal of existing temporary differences and the implementation of tax planning strategies. Projected future taxable income is based on expected results and assumptions as to the jurisdiction in which the income will be earned. The expected timing of the reversals of existing temporary differences is based on current tax law and the Company’s tax methods of accounting. The Company also reviews its tax activities and evaluates uncertain tax positions using a two-step approach. The first step is to evaluate the tax position for recognition by determining if the weight of available evidence indicates that it is more likely than not that the position will be sustained on audit, including resolution of related appeals or litigation processes, if any. The second step is to measure the tax benefit, which is the largest amount that is more than 50% likely of being realized upon ultimate settlement. The Company’s policy is to recognize interest and penalties accrued on unrecognized tax benefits as part of income tax expense.
Other Comprehensvie Income (Loss) [Policy Text Block]	Other Comprehensive Income (Loss) Components of other comprehensive income (loss) include currency translation adjustments, changes related to pension liabilities, net of tax, and unrealized gains (losses) on hedging activities, net of tax. Foreign currency translation adjustments generally are not adjusted for income taxes as they relate to indefinite investments in non-U.S. operations. Accumulated other comprehensive income (loss) also includes, net of tax, actuarial gains or losses, prior service costs or credits and transition assets and obligations that are not recognized currently as components of net periodic pension cost.
Concentration Risk, Credit Risk, Policy [Policy Text Block]	Concentration of Credit Risk In the normal course of business, the Company is exposed to credit risk. The principal concentrations of credit risk are cash and cash equivalents, short-term investments, accounts receivable and derivative instruments. The Company regularly monitors credit risk exposures and takes steps to mitigate the likelihood of these exposures resulting in a loss. Historically, credit losses on accounts receivable have not been material because of the large concentration of revenues with a small number of large, established companies. The Company does not require collateral or other security to support accounts receivable. The Company evaluates the creditworthiness of its clients in conjunction with its revenue recognition processes, as discussed above, as well as through its ongoing collectability assessment processes for accounts receivable. The Company maintains an allowance for doubtful accounts receivable based upon factors surrounding the credit risk of specific clients, historical trends and other information. The Company limits its counterparty credit risk exposures by entering into derivative contracts with financial institutions that are investment grade rated.
Cash Equivalents [Policy Text Block]	Cash and Cash Equivalents Cash and cash equivalents consist of cash on hand and short-term, highly liquid investments with original maturities of three months or less.
Receivables [Policy Text Block]	Receivables and Allowance for Doubtful Accounts Trade receivables are comprised primarily of amounts owed to the Company by clients and are presented net of an allowance for doubtful accounts of $5.3 and $8.1 at December 31, 2015 and 2014 , respectively. Contracts with individual clients determine when receivables are due, generally within 30 - 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. 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.
Property and Equipment [Policy Text Block]	Property and Equipment Property and equipment are stated at cost. Depreciation is based on the straight-line method over the estimated useful lives of the assets. Buildings are generally depreciated over a 30 -year life, software over a three - to ten -year life and equipment generally over a three - to five -year life. Leasehold improvements are depreciated over the shorter of their estimated useful life or the remaining term of the associated lease. Assets held under capital leases are recorded at the lower of the net present value of the minimum lease payments or the fair value of the leased asset at the inception of the lease. Depreciation expense for assets held under captial lease is computed using the straight-line method over the shorter of the estimated useful lives of the assets or the period of the related lease. Included within Property and equipment is initial cost of $13.2 related to assets under capital lease arrangements. The Company reviews property and equipment asset groups for impairment whenever events or changes in circumstances indicate the carrying amount of an asset may not be recoverable. The Company monitors these changes and events on at least a quarterly basis. Examples of events or changes in circumstances could include, but are not limited to, a prolonged economic downturn, current period operating or cash flow losses combined with a history of losses or a forecast of continuing losses associated with the use of an asset group, or a current expectation that an asset group will be sold or disposed of before the end of its previously estimated useful life. Recoverability is based upon projections of anticipated future undiscounted cash flows associated with the use and eventual disposal of the property and equipment asset groups, as well as specific appraisals in certain instances. Reviews occur at the lowest level for which identifiable cash flows are largely independent of cash flows associated with other property and equipment asset groups. If the future undiscounted cash flows result in a value that is less than the carrying value, then the long-lived asset is considered impaired and a loss is recognized based on the amount by which the carrying amount exceeds the estimated fair value. Various factors that the Company uses in determining the impact of these assessments include the expected useful lives of long-lived assets and our ability to realize any undiscounted cash flows in excess of the carrying amounts of such asset groups, and are affected primarily by changes in the expected use of the assets, changes in technology or development of alternative assets, changes in economic conditions, changes in operating performance and changes in expected future cash flows. Because judgment is involved in determining the fair value of property and equipment asset groups, there is risk that the carrying value of these assets may require adjustment in future periods.
Internal Use Software [Policy Text Block]	Internal Use Software The Company capitalizes certain expenditures for software that is purchased or internally developed for use in the business. During 2015 , 2014 , and 2013 , amounts capitalized for internally developed software were $14.2 , $4.9 and $1.0 , respectively. The increase in capitalized costs during 2015 is a result of certain information technology infrastructure initiatives. Amortization of internal use software begins when the software is ready for service and continues on the straight-line method over the estimated useful life
Business Combinations Policy [Policy Text Block]	Business Combinations Accounting for acquisitions requires the Company to recognize separately from goodwill the assets acquired and the liabilities assumed at their acquisition date fair values. Goodwill as of the acquisition date is measured as the excess of consideration transferred over the net of the acquisition date fair values of the assets acquired and the liabilities assumed. While we use our best estimates and assumptions to accurately value assets acquired and liabilities assumed at the acquisition date as well as contingent consideration, where applicable, our estimates are inherently uncertain and subject to refinement. As a result, during the measurement period, which may be up to one year from the acquisition date, we record adjustments to the assets acquired and liabilities assumed with corresponding adjustments to goodwill. Upon the conclusion of the measurement period or final determination of the values of assets acquired or liabilities assumed, whichever comes first, any subsequent adjustments are recorded to our consolidated statements of operations. Refer to Note 3 of the Notes to the Consolidated Financial Statements for a discussion of the Stream acquisition.
Goodwill and Other Intangibles [Policy Text Block]	Goodwill and Other Intangibles As discussed more fully in Note 6, goodwill is reviewed at the reporting unit level for impairment as of October 1 each year and at other times if events have occurred or circumstances exist that indicate the carrying value of goodwill may no longer be recoverable. The first step of the impairment test compares the fair value of a reporting unit with its carrying amount, including the goodwill allocated to the reporting unit (Step 1). If the fair value of the reporting unit is in excess of the carrying value, the related goodwill is considered not to be impaired and no further analysis is necessary. If the carrying amount of the reporting unit exceeds the fair value, there is an indication of potential impairment and a second step of testing is performed to measure the amount of the impairment, if any, for that reporting unit. When required, the second step compares the implied fair value of the reporting unit goodwill with the carrying amount of the reporting unit goodwill. The implied fair value of goodwill is determined in the same manner as the amount of goodwill recognized in a business combination, which is the excess of the fair value of the reporting unit determined in step one over the fair value of the net assets and identifiable intangibles as if the reporting unit were being acquired. Any excess of the carrying value of the reporting unit goodwill over the implied fair value of the reporting unit goodwill will be recorded as an impairment loss. An impairment charge recognized cannot exceed the amount of goodwill allocated to a reporting unit and cannot be reversed subsequently even if the fair value of the reporting unit recovers. Fair value of the reporting unit is determined using the income approach with corroboration from the market approach. Under the market approach, fair value is based on revenue and earnings multiples for guideline public companies in the reporting unit’s peer group. The market approach requires judgment regarding the selection of guideline companies. Under the income approach, value is dependent on the present value of net cash flows to be derived from ownership of the reporting unit. The income approach requires significant judgment including estimates about future cash flows and discount rates. Other intangibles, primarily customer relationship assets and trademarks, are amortized over a straight-line basis with estimated useful lives ranging from four to seventeen years and are evaluated periodically if events or circumstances indicate a possible inability to recover their carrying amounts.
Postemployment Benefits [Policy Text Block]	Postemployment Benefits The funded status of the Company’s pension and other postretirement benefit plans is recognized in the Consolidated Balance Sheets. The funded status is measured as the difference between the fair value of plan assets and the benefit obligation at December 31, the measurement date. For defined benefit pension plans, the benefit obligation is the projected benefit obligation (PBO) and, for the other postretirement benefit plans, the benefit obligation is the accumulated postretirement benefit obligation (APBO). The PBO represents the actuarial present value of benefits expected to be paid upon retirement. For active plans, the present value reflects estimated future compensation levels. The APBO represents the actuarial present value of postretirement benefits attributed to employee services already rendered. The fair value of plan assets represents the current market value of assets held by an irrevocable trust fund for the sole benefit of participants. The measurement of the benefit obligation is based on the Company’s estimates and actuarial valuations. These valuations reflect the terms of the plans and use participant-specific information such as compensation, age and years of service, as well as certain key assumptions that require significant judgment, including, but not limited to, estimates of discount rates, expected return on plan assets, rate of compensation increases, interest crediting rates and mortality rates. For additional information regarding plan assumptions and the current financial position of the pension and other postretirement plans, see Note 9. The Company provides severance benefits to certain employees. The Company accrues the benefits when it becomes probable that such benefits will be paid and when sufficient information exists to make reasonable estimates of the amounts to be paid.
Government Grants [Policy Text Block]	Government Grants From time to time, the Company receives grants from local or state governments as an incentive to locate or retain operations in their jurisdictions. Depending on the arrangement, the grants are either received up-front or at the time the Company achieves the milestones set forth in the grant. The Company’s policy is to record the grant funds received as deferred credit and to amortize the deferred credit as a reduction of cost of providing services and products sold or selling, general and administrative expense as the milestones are met over the term of the grant.
Derivative Instruments [Policy Text Block]	Derivative Instruments 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 and interest rates. The Company currently uses only cash flow hedges. These instruments are hedges of forecasted transactions or of the variability of cash flows to be received or paid related to a recognized asset or liability. The Company generally enters into hedging contracts expiring within 36 months as hedges of anticipated cash flows denominated in foreign currencies. These contracts are entered into to protect against the risk that the eventual cash flows resulting from such transactions will be adversely affected by changes in exchange rates. In using derivative financial instruments to hedge exposures to changes in exchange rates, the Company exposes itself to counterparty credit risk. All derivatives, including foreign currency exchange contracts, are recognized in the Consolidated Balance Sheets at fair value. Fair values for the Company’s derivative financial instruments are based on quoted market prices of comparable instruments or, if none are available, on pricing models or formulas using current assumptions. On the date the derivative contract is entered into, the Company determines whether the derivative contract qualifies for designation as a hedge. For derivatives that are designated as hedges, the Company further designates the hedge as either a fair value or cash flow hedge; all currently existing hedges have been designated as cash flow hedges. Changes in the fair value of derivatives that are highly effective and designated as cash flow hedges are reported as a component of Other Comprehensive (Loss) Income and reclassified into earnings in the same line-item associated with the forecasted transaction and in the same periods during which the hedged transaction impacts earnings. The Company formally documents all relationships between hedging instruments and hedged items, as well as its risk management objective and strategy for undertaking various hedging activities. This process includes linking all derivatives that are designated as fair value or cash flow hedges to specific assets and liabilities on the balance sheet or to forecasted transactions, respectively. The Company also formally assesses, both at the hedge’s inception and on an ongoing basis, whether the derivatives that are used in hedging transactions are highly effective in offsetting changes in the fair value or cash flows of hedged items. When it is determined that a derivative is not highly effective as a hedge or that it has ceased to be a highly effective hedge, the Company discontinues hedge accounting prospectively. The Company also periodically enters into hedging contracts that are not designated as hedges. The purpose of the majority of these derivative instruments is to protect the Company against foreign currency exposure pertaining to receivables, payables and intercompany transactions that are denominated in currencies different from the functional currencies of the Company or the respective subsidiaries. The Company records changes in the fair value of these derivative instruments in the Consolidated Statements of Income within Other income, net.
Equity-Method Investments [Policy Text Block]	Investments Management determines the appropriate classification of securities at the time of purchase and re-evaluates such designation as of each balance sheet date. Currently all investment securities are classified as trading, and are reported within short-term investments in the Consolidated Balance Sheets. Trading 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 is included in Other (expense) income, net.
Fair Value of Financial Instruments, Policy [Policy Text Block]	Fair Value Measurements The Company applies fair value accounting for all financial assets and liabilities and non-financial assets and liabilities that are recognized or disclosed at fair value in the consolidated financial statements on a recurring basis. The Company defines fair value as the price that would be received from selling an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. When determining the fair value measurements for assets and liabilities, the Company considers the principal or most advantageous market in which the Company would transact and the market-based risk measurements or assumptions that market participants would use in pricing the asset or liability, such as inherent risk, transfer restrictions and credit risk.
New Accounting Pronouncements, Policy [Policy Text Block]	New Accounting Pronouncements In November 2015, the Financial Accounting Standards Board (FASB) issued Accounting Standards Update (ASU) 2015-17, “Balance Sheet Classification of Deferred Taxes.” This ASU requires all deferred tax assets and liabilities to be classified as non-current on the balance sheet instead of separating into current and non-current amounts. This update is effective for interim and annual periods beginning after December 15, 2016 and may be applied on a prospective or retrospective basis. The Company elected to early adopt this standard on a retrospective basis as of December 31, 2015. The impact of this change in accounting principle on balances previously reported as of December 31, 2014 was as follows: As of December 31, 2014 Consolidated Balance Sheet Caption Previously Reported Change Currently Reported Total current assets $ 890.9 (107.2 ) $ 783.7 Total Assets $ 2,516.5 (100.4 ) $ 2,416.1 Total current liabilities $ 368.5 (0.6 ) $ 367.9 Total Liabilities $ 1,225.0 (100.4 ) $ 1,124.6 In April 2015, the FASB issued ASU 2015-03, “Simplifying the Presentation of Debt Issuance Costs.” This ASU requires debt issuance costs to be presented in the balance sheet as a direct deduction from the carrying value of the associated debt liability, consistent with the presentation of a debt discount. This ASU is effective for interim and annual periods beginning after December 15, 2015 and is required to be applied retrospectively. This standard is not expected to have a material effect on the Company’s consolidated financial statements.
