Business Combinations [Abstract]
Acquisitions	Note 2. Acquisitions Clearlink On April 1, 2016, the Company acquired 100% of the outstanding membership units of Clearlink through a merger of Clearlink with and into a subsidiary of the Company (the “Merger”). Clearlink, with its operations located in the United States, is an inbound demand generation and sales conversion platform serving numerous Fortune 500 business-to-consumer and business-to-business clients across various industries and subsectors, including telecommunications, satellite television, home security and insurance. The results of Clearlink’s operations have been included in the Company’s consolidated financial statements since April 1, 2016 (the “Clearlink acquisition date”). The strategic acquisition of Clearlink expands the Company’s suite of service offerings while creating differentiation in the marketplace, broadening its addressable market opportunity and extending executive level reach within the Company’s existing clients’ organization. This resulted in the Company paying a substantial premium for Clearlink resulting in the recognition of goodwill. Pursuant to Federal income tax laws, intangible assets and goodwill from the Clearlink acquisition are deductible over a 15 year amortization period. The Clearlink purchase price totaled $207.9 million, consisting of the following: Total Cash (1) $ 209,186 Working capital adjustment (1,278) $ 207,908 (1) Approximately $2.6 million of the purchase price was placed in an escrow account as security for the indemnification obligations of Clearlink’s members under the merger agreement. The Company accounted for the Clearlink acquisition in accordance with ASC 805, “ Business Combinations Business Combinations (Topic 805) Simplifying the Accounting for Measurement-Period Adjustments The following table summarizes the estimated Clearlink acquisition date fair values of the assets acquired and liabilities assumed, all included in the Americas segment (in thousands): April 1, 2016 Cash and cash equivalents $ 2,584 Receivables (1) 16,801 Prepaid expenses 1,553 Total current assets 20,938 Property and equipment 12,869 Goodwill 70,223 Intangibles 121,400 Deferred charges and other assets 229 Accounts payable (3,564) Accrued employee compensation and benefits (1,610) Deferred revenue (4,620) Other accrued expenses and current liabilities (6,324) Total current liabilities (16,118) Other long-term liabilities (1,633) $ 207,908 (1) Fair values are based on management’s estimates and assumptions including variations of the income approach, the cost approach and the market approach.

The pro forma financial information is not indicative of the results of operations that would have been achieved if the acquisition and related borrowings had taken place on January 1, 2016 and 2015 (in thousands): Three Months Ended September 30, Nine Months Ended September 30, 2016 2015 2016 2015 Revenues $ 385,743 $ 352,280 $ 1,104,720 $ 1,042,353 Net income $ 21,277 $ 21,655 $ 47,172 $ 51,105 Net income per common share: Basic $ 0.51 $ 0.52 $ 1.13 $ 1.22 Diluted $ 0.50 $ 0.51 $ 1.12 $ 1.21 These amounts have been calculated to reflect the additional depreciation, amortization, interest expense and rent expense that would have been incurred assuming the fair value adjustments and borrowings occurred on January 1, 2016 and January 1, 2015, together with the consequential tax effects. In addition, these amounts exclude costs incurred which are directly attributable to the acquisition, and which do not have a continuing impact on the combined companies’ operating results. Included in these costs are advisory and legal costs, net of the tax effects. Acquisition-related costs associated with Clearlink in the accompanying Condensed Consolidated Statement of Operations were as follows (none in 2015) (in thousands): Three Months Ended September 30, 2016 Nine Months Ended September 30, 2016 Severance costs: (1) Americas $ 162 $ 162 Transaction and integration costs: (1) Americas — 29 Other 39 4,415 39 4,444 Total merger and integration costs $ 201 $ 4,606 (1) Qelp On July 2, 2015, the Company’s wholly-owned subsidiaries, Sykes Enterprises Incorporated B.V. and Sykes Enterprises Incorporated Holdings B.V., both Netherlands companies, entered into a definitive Share Sale and Purchase Agreement (the “Qelp Purchase Agreement”) with MobileTimes B.V., Yarra B.V., From The Mountain Consultancy B.V. and Sticting Administratiekantoor Qelp (the “Sellers”), all of which are Netherlands companies, to acquire all of the outstanding shares of Qelp B.V. and its wholly owned subsidiary (together, known as “Qelp”.) The strategic acquisition of Qelp (the “Qelp acquisition”) was to further broaden and strengthen the Company’s service portfolio around digital self-service customer support and extend its reach into adjacent, but complementary, markets. Pursuant to Federal income tax regulations, no amount of intangibles or goodwill from this acquisition will be deductible for tax purposes. The results of Qelp’s operations have been included in the Company’s consolidated financial statements since its acquisition on July 2, 2015 (the “Qelp acquisition date”). The consideration consisted of an initial purchase price and a contingent purchase price. The initial purchase price of $9.8 million, including certain post-closing adjustments relating to Qelp’s working capital, was funded through cash on hand upon the closing of the transaction on July 2, 2015. The initial contingent purchase price to be paid over a three year period was based on achieving targets tied to revenues and earnings before interest, income taxes, depreciation and amortization (“EBITDA”) for the years ended December 31, 2016, 2017 and 2018, not to exceed EUR 10.0 million. As of the Qelp acquisition date, the total consideration paid or to be paid by the Company for the Qelp acquisition is summarized below (in thousands): Total Cash $ 9,885 Contingent consideration 6,000 Working capital adjustment (65) $ 15,820 The fair value of the contingent consideration was estimated using the discounted cash flow method, and was included in “Other long-term liabilities” in the accompanying Condensed Consolidated Balance Sheets (see Note 4, Fair Value, for further information). As part of the discounted cash flow method, the Company calculated an adjusted weighted average cost of capital (“WACC”) specifically attributable to the future payments of the contingent consideration. Based on the forecasted revenue and profitability scenarios and their respective probabilities of occurrence, the Company estimated the present value of the probability-adjusted future payments utilizing an adjusted WACC for the potential future payments. The Company believes that its estimates and assumptions are reasonable, but there is significant judgment involved. Changes in the fair value of the contingent consideration liabilities subsequent to the acquisition will be recorded in the Company’s consolidated financial statements. On September 26, 2016, the Company entered into an addendum to the Qelp Purchase Agreement with the Sellers to settle the outstanding contingent consideration for EUR 4.0 million ($4.5 million as of September 30, 2016) to be paid on June 30, 2017. The Company accounted for the Qelp acquisition in accordance with ASC 805 , The following table summarizes the Qelp acquisition date fair values of the assets acquired and liabilities assumed, all included in the EMEA segment (in thousands): July 2, 2015 Cash and cash equivalents $ 450 Receivables (1) 1,471 Prepaid expenses 24 Total current assets 1,945 Property and equipment 2,168 Goodwill 10,054 Intangibles 6,000 Deferred charges and other assets 55 Short-term debt (323) Accrued employee compensation and benefits (207) Income taxes payable (94) Deferred revenue (967) Other accrued expenses and current liabilities (1,030) Total current liabilities (2,621) Other long-term liabilities (2) (1,781) $ 15,820 (1) (2) Fair values were based on management’s estimates and assumptions including variations of the income approach, the cost approach and the market approach.

Fair Value of Financial Instruments — ● Cash, short-term and other investments, investments held in rabbi trust and accounts payable — ● Foreign currency forward contracts and options — ● Embedded derivatives — ● Long-term debt — ● Contingent consideration — Fair Value Measurements ASC 825 “ Financial Instruments” Determination of Fair Value — If quoted market prices are not available, fair value is based upon internally developed valuation techniques that use, where possible, current market-based or independently sourced market parameters, such as interest rates, currency rates, etc. Assets or liabilities valued using such internally generated valuation techniques are classified according to the lowest level input or value driver that is significant to the valuation. Thus, an item may be classified in Level 3 even though there may be some significant inputs that are readily observable. The following section describes the valuation methodologies used by the Company to measure assets and liabilities at fair value on a recurring basis, including an indication of the level in the fair value hierarchy in which each asset or liability is generally classified. Money Market and Open-End Mutual Funds Foreign Currency Forward Contracts and Options — Embedded Derivatives — Investments Held in Rabbi Trust — Guaranteed Investment Certificates — Contingent Consideration including the country of operation, the nature of services and complexity of the acquired business, and other similar factors, all of which are significant inputs not observable in the market. Significant increases or decreases in any of the inputs in isolation would result in a significantly higher or lower fair value measurement. In connection with the addendum to the Qelp Purchase Agreement with the Sellers dated September 26, 2016, the Company agreed to settle the outstanding contingent consideration for EUR 4.0 million ($4.5 million as of September 30, 2016) to be paid on June 30, 2017. The Company’s assets and liabilities measured at fair value on a recurring basis subject to the requirements of ASC 820 consist of the following (in thousands): Fair Value Measurements at September 30, 2016 Using: Balance at Quoted Prices Significant Significant September 30, 2016 Level (1) Level (2) Level (3) Assets: Foreign currency forward and option contracts (1 ) $ 492 $ - $ 492 $ - Embedded derivatives (1 ) 207 - - 207 Equity investments held in rabbi trust for the Deferred Compensation Plan (2 ) 7,161 7,161 - - Debt investments held in rabbi trust for the Deferred Compensation Plan (2 ) 1,959 1,959 - - Guaranteed investment certificates (3 ) 95 - 95 - $ 9,914 $ 9,120 $ 587 $ 207 Liabilities: Long-term debt (4 ) $ 272,000 $ - $ 272,000 $ - Foreign currency forward and option contracts (1 ) 3,713 - 3,713 - Embedded derivatives (1 ) 31 - - 31 Contingent consideration included in “Other accrued expenses and current liabilities” (5 ) 6,272 - - 6,272 Contingent consideration included in “Other long-term liabilities” (5 ) 920 - - 920 $ 282,936 $ - $ 275,713 $ 7,223 Assets: Foreign currency forward and option contracts (1 ) $ 10,962 $ - $ 10,962 $ - Equity investments held in rabbi trust for the Deferred Compensation Plan (2 ) 6,229 6,229 - - Debt investments held in rabbi trust for the Deferred Compensation Plan (2 ) 1,622 1,622 - - Guaranteed investment certificates (3 ) 86 - 86 - $ 18,899 $ 7,851 $ 11,048 $ - Liabilities: Long-term debt (4 ) $ 70,000 $ - $ 70,000 $ - Foreign currency forward and option contracts (1 ) 835 - 835 - Contingent consideration included in “Other long-term liabilities” (5 ) 6,280 - - $ 77,115 $ - $ 70,835 $ 6,280 (1) (2) (3) (4) (5) Reconciliations of Fair Value Measurements Categorized within Level 3 of the Fair Value Hierarchy Embedded Derivatives in Lease Agreements A rollforward of the net asset (liability) activity in the Company’s fair value of the embedded derivatives is as follows (in thousands) (none in 2015): Fair Value Balance at January 1, 2016 $ - Gain (loss) recognized in “Other income (expense)” (1) 176 Effect of foreign currency - Balance at September 30, 2016 $ 176 Unrealized gain (loss) for the three months ended September 30, 2016 $ 128 Unrealized gain (loss) for the nine months ended September 30, 2016 $ 171 (1) Contingent Consideration A rollforward of the activity in the Company’s fair value of the contingent consideration is as follows (in thousands): Fair Value Balance at January 1, 2015 $ - Acquisition (1) 6,000 Payments - Imputed interest 408 Fair value adjustments - Effect of foreign currency (128) Balance at December 31, 2015 6,280 Acquisition (2) 2,779 Payments - Imputed interest 716 Fair value adjustments (2,798) Effect of foreign currency 215 Balance at September 30, 2016 $ 7,192 (1) (2) The Company recorded a fair value adjustment of $2.6 million to the Qelp contingent consideration in “General and administrative” in the accompanying Condensed Consolidated Statements of Operations for the three and nine months ended September 30, 2016 due to the execution of an addendum to the Qelp Purchase Agreement subject to which the Company will pay the Sellers EUR 4.0 million on June 30, 2017 ($4.5 million as of September 30, 2016). The Company recorded a fair value adjustment of $0.2 million to the Clearlink contingent consideration in “General and administrative” in the accompanying Condensed Consolidated Statements of Operations in the three and nine months ended September 30, 2016 due to changes in the probability of achievement of certain revenue targets. The Company accretes interest expense each period using the effective interest method until the contingent consideration reaches the estimated future value of $7.3 million. Interest expense related to the contingent consideration is included in “Interest (expense)” in the accompanying Condensed Consolidated Statements of Operations. Non-Recurring Fair Value Certain assets, under certain conditions, are measured at fair value on a nonrecurring basis utilizing Level 3 inputs, like those associated with acquired businesses, including goodwill, other intangible assets and other long-lived assets. For these assets, measurement at fair value in periods subsequent to their initial recognition would be applicable if these assets were determined to be impaired. The adjusted carrying values for assets measured at fair value on a nonrecurring basis (no liabilities) subject to the requirements of ASC 820 were not material at September 30, 2016 and December 31, 2015.

For the annual goodwill impairment test, the Company elected to forgo the option to first assess qualitative factors and performed its annual two-step goodwill impairment test as of July 31, 2016. Under ASC 350, the carrying value of assets is calculated at the reporting unit level. The quantitative assessment of goodwill includes comparing a reporting unit’s calculated fair value to its carrying value. The calculation of fair value requires significant judgments including estimation of future cash flows, which is dependent on internal forecasts, estimation of the long-term rate of growth, the useful life over which cash flows will occur and determination of the Company’s weighted average cost of capital. Changes in these estimates and assumptions could materially affect the determination of fair value and/or conclusions on goodwill impairment for each reporting unit. If the fair value of the reporting unit is less than its carrying value, goodwill is considered impaired and an impairment loss is recorded to the extent that the fair value of the goodwill within the reporting unit is less than its carrying value. The process of evaluating the fair value of the reporting units is highly subjective and requires significant judgment and estimates as the reporting units operate in a number of markets and geographical regions. The Company used an average of the income and market approaches to determine its best estimates of fair value which incorporated the following significant assumptions: ● Revenue projections, including revenue growth during the forecast periods; ● EBITDA margin projections over the forecast periods; ● Estimated income tax rates; ● Estimated capital expenditures; and ● Discount rates based on various inputs, including the risks associated with the specific reporting units as well as their revenue growth and EBITDA margin assumptions. As of July 31, 2016, the Company concluded that goodwill was not impaired for all six of its reporting units with goodwill, based on fair value estimates developed using generally accepted valuation techniques and the significant assumptions outlined above. While the fair values of four of the six reporting units were substantially in excess of their carrying value, the Qelp reporting unit’s fair value exceeded its carrying value (although not substantially) and the newly acquired Clearlink reporting unit’s fair value approximated its carrying value due to the proximity to the acquisition date of April 1, 2016. The Clearlink reporting unit’s fair value of $207.9 million includes $70.2 million of goodwill. The Qelp and Clearlink reporting units are at risk for future impairment if projected operating results are not met or other inputs into the fair value measurement change. However, as of September 30, 2016, there were no indicators of impairment.

Income Tax Disclosure [Abstract]
Income Taxes	Note 13. Income Taxes The Company’s effective tax rate was 27.2% and 14.2% for the three months ended September 30, 2016 and 2015, respectively, and 28.9% and 22.1% for the nine months ended September 30, 2016 and 2015, respectively. The increase in the effective tax rates is predominately due to the recognition in the prior period of a $2.2 million previously unrecognized tax benefit, inclusive of penalties and interest, arising from statute of limitations expirations and a $1.3 million reversal of a valuation allowance on deferred tax assets where it is more likely than not the assets will be realized due to the current financial position and results of operations for the current and preceding years. The increase in the effective tax rates was also affected by several additional factors, including shifts in earnings among the various jurisdictions in which the Company operates, none of which are individually material. The difference between the Company’s effective tax rates for the three and nine months ended September 30, 2016 as compared to the U.S. statutory federal income tax rate of 35.0% was primarily due to the recognition of tax benefits resulting from foreign tax rate differentials, income earned in certain tax holiday jurisdictions, changes in unrecognized tax benefits, adjustments of valuation allowances and tax credits, partially offset by the tax impact of permanent differences and foreign withholding taxes. Earnings associated with the investments in the Company’s foreign subsidiaries are considered to be indefinitely reinvested outside of the U.S. Therefore, a U.S. provision for income taxes on those earnings or translation adjustments has not been recorded, as permitted by criterion outlined in ASC 740 “ Income Taxes. The Company is currently under audit in several tax jurisdictions. The Company received assessments for the Canadian 2003-2009 audit. Requests for Competent Authority Assistance were filed with both the Canadian Revenue Agency and the U.S. Internal Revenue Service and the Company paid mandatory security deposits to Canada as part of this process. The total amount of deposits, net of the effects of foreign exchange rate adjustments, are $14.1 million and $13.4 million as of September 30, 2016 and December 31, 2015, respectively, and are included in “Deferred charges and other assets” in the accompanying Condensed Consolidated Balance Sheets. Although the outcome of examinations by taxing authorities is always uncertain, the Company believes it is adequately reserved for these audits and resolution is not expected to have a material impact on its financial condition and results of operations. The significant tax jurisdictions currently under audit are as follows: Tax Jurisdiction Tax Years Ended Canada 2003 to 2009

This cost is expected to be recognized over a weighted average period of 1.9 years. Non-Employee Director Fee Plan — The 2004 Fee Plan also provided that each non-employee director would receive, on the day after the annual shareholders meeting, an annual retainer for service as a non-employee director (the “Annual Retainer”). Prior to May 17, 2012, the Annual Retainer was $95,000, of which $50,000 was payable in cash, and the remainder was paid in stock. The annual grant of cash vested in four equal quarterly installments, one-fourth on the day following the annual meeting of shareholders, and an additional one-fourth on each successive third monthly anniversary of the date of grant. The annual grant of shares paid to non-employee directors prior to May 17, 2012 vests in eight equal quarterly installments, one-eighth on the day following the annual meeting of shareholders, and an additional one-eighth on each successive third monthly anniversary of the date of grant. On May 17, 2012, upon the recommendation of the Compensation Committee, the Board adopted the Fifth Amended and Restated Non-Employee Director Fee Plan (the “Amendment”), which increased the common stock component of the Annual Retainer by $30,000, resulting in a total Annual Retainer of $125,000, of which $50,000 was payable in cash and the remainder paid in stock. In addition, the Amendment also changed the vesting period for the annual equity award, from a two-year vesting period, to a one-year vesting period (consisting of four equal quarterly installments, one-fourth on the date of grant and an additional one-fourth on each successive third monthly anniversary of the date of grant). The award lapses with respect to all unpaid cash and unvested shares in the event the non-employee director ceases to be a director of the Company, and any unvested shares and unpaid cash are forfeited. In addition to the Annual Retainer award, the 2004 Fee Plan also provided for any non-employee Chairman of the Board to receive an additional annual cash award of $100,000, and each non-employee director serving on a committee of the Board to receive an additional annual cash award. The additional annual cash award for the Chairperson of the Audit Committee is $20,000 and Audit Committee members’ are entitled to an annual cash award of $10,000. The annual cash awards for the Chairpersons of the Compensation Committee, Finance Committee and Nominating and Corporate Governance Committee are $15,000, $12,500 and $12,500, respectively, and all other members of such committees are entitled to an annual cash award of $7,500. The 2004 Fee Plan expired in May 2014, prior to the 2014 Annual Shareholder Meeting. In March 2014, upon the recommendation of the Compensation Committee, the Board determined that, following the expiration of the 2004 Fee Plan, the compensation of non-employee Directors should continue on the same terms as provided in the Fifth Amended and Restated Non-Employee Director Fee Plan, except the amounts of cash and equity grants shall be determined annually by the Board, and that the stock portion of such compensation would be issued under the 2011 Plan. At the Board’s regularly scheduled meeting on December 10, 2014, upon the recommendation of the Compensation Committee, the Board determined that the amount of the cash and equity compensation payable to non-employee directors beginning on the date of the 2015 annual shareholder meeting would be increased as follows: cash compensation would be increased by $5,000 per year to a total of $55,000 and equity compensation would be increased by $25,000 per year to a total of $100,000. No change would be made in the additional amounts payable to the Chairman of the Board or the Chairs or members of the various Board committees for their service on such committees, and no changes would be made in the payment terms described above for such cash and equity compensation. At the Board’s regularly scheduled meeting on December 9, 2015, upon the recommendation of the Compensation Committee, the Board determined that the amount of the cash and equity compensation payable to non-employee directors beginning on the date of the 2016 annual shareholders’ meeting would remain unchanged. The Board may pay additional cash compensation to any non-employee director for services on behalf of the Board over and above those typically expected of directors, including but not limited to service on a special committee of the Board.

Fair Value of Financial Instruments — ● Cash, short-term and other investments, investments held in rabbi trust and accounts payable — ● Foreign currency forward contracts and options — ● Embedded derivatives — ● Long-term debt — ● Contingent consideration — Fair Value Measurements
Financial Instruments	ASC 825 “ Financial Instruments” Determination of Fair Value — If quoted market prices are not available, fair value is based upon internally developed valuation techniques that use, where possible, current market-based or independently sourced market parameters, such as interest rates, currency rates, etc. Assets or liabilities valued using such internally generated valuation techniques are classified according to the lowest level input or value driver that is significant to the valuation. Thus, an item may be classified in Level 3 even though there may be some significant inputs that are readily observable. The following section describes the valuation methodologies used by the Company to measure assets and liabilities at fair value on a recurring basis, including an indication of the level in the fair value hierarchy in which each asset or liability is generally classified. Money Market and Open-End Mutual Funds Foreign Currency Forward Contracts and Options — Embedded Derivatives — Investments Held in Rabbi Trust — Guaranteed Investment Certificates — Contingent Consideration including the country of operation, the nature of services and complexity of the acquired business, and other similar factors, all of which are significant inputs not observable in the market. Significant increases or decreases in any of the inputs in isolation would result in a significantly higher or lower fair value measurement.

Deferred Revenue	The Company receives up-front fees in connection with certain contracts. The deferred revenue is earned over the service periods of the respective contracts, which range from 30 days to seven years. Deferred revenue included in current liabilities in the accompanying Condensed Consolidated Balance Sheets includes the up-front fees associated with services to be provided over the ensuing twelve month period and the up-front fees associated with services to be provided over multiple years in connection with contracts that contain cancellation and refund provisions, whereby the manufacturers or customers can terminate the contracts and demand pro-rata refunds of the up-front fees with short notice. Deferred revenue from estimated penalties and holdbacks results from the failure to meet specified minimum service levels in certain contracts and other performance based contingencies. Deferred revenue from estimated chargebacks reflects the right of certain of the Company’s clients to chargeback accounts that do not meet certain requirements for specified periods after a sale has occurred.
Income Taxes	Earnings associated with the investments in the Company’s foreign subsidiaries are considered to be indefinitely reinvested outside of the U.S. Therefore, a U.S. provision for income taxes on those earnings or translation adjustments has not been recorded, as permitted by criterion outlined in ASC 740 “ Income Taxes.
Earnings Per Share	Basic earnings per share are based on the weighted average number of common shares outstanding during the periods. Diluted earnings per share includes the weighted average number of common shares outstanding during the respective periods and the further dilutive effect, if any, from stock appreciation rights, restricted stock, restricted stock units and shares held in rabbi trust using the treasury stock method.
Segments and Geographic Information	The Company operates within two regions, the Americas and EMEA. Each region represents a reportable segment comprised of aggregated regional operating segments, which portray similar economic characteristics. The Company aligns its business into two segments to effectively manage the business and support the customer care needs of every client and to respond to the demands of the Company’s global customers.
