Accounting Policies [Abstract]
Summary of significant accounting policies	2. Summary of significant accounting policies (a) Basis of preparation and principles of consolidation The accompanying consolidated financial statements have been prepared in accordance with U.S. generally accepted accounting principles (U.S. GAAP). The accompanying consolidated financial statements reflect all adjustments that management considers necessary for a fair presentation of the results of operations for these periods. The accompanying financial statements have been prepared on a consolidated basis and reflect the financial statements of Genpact Limited, a Bermuda company, and all of its subsidiaries that are more than 50% owned and controlled. When the Company does not have a controlling interest in an entity but exerts significant influence over the entity, the Company applies the equity method of accounting. All intercompany transactions and balances are eliminated in consolidation. Non-controlling interest in subsidiaries that is redeemable outside of the Company’s control for cash or other assets is reflected in the mezzanine section between liabilities and equity in the consolidated balance sheets at the redeemable value, which approximates fair value. Redeemable non-controlling interest is adjusted to its fair value at each balance sheet date. Any resulting increases or decreases in the estimated redemption amount are affected by corresponding charges to additional paid-in capital. The share of non-controlling interest in subsidiary earnings is reflected in net loss (income) attributable to redeemable non-controlling interest in the consolidated statements of income. (b) Use of estimates The preparation of consolidated financial statements in accordance with U.S. GAAP requires management to make estimates and assumptions that affect the amounts reported in the consolidated financial statements. Significant items subject to such estimates and assumptions include the useful lives of property, plant and equipment, intangibles and goodwill, revenue recognition, reserves for doubtful receivables, valuation allowances for deferred tax assets, the valuation of derivative financial instruments, measurements of stock-based compensation, assets and obligations related to employee benefits, and income tax uncertainties and other contingencies. Management believes that the estimates used in the preparation of the consolidated financial statements are reasonable. Although these estimates are based upon management’s best knowledge of current events and actions, actual results could differ from these estimates. Any changes in estimates are adjusted prospectively in the Company’s consolidated financial statements. (c) Changes in accounting policies Except as described below, the Company has applied accounting policies consistently to all periods presented in these consolidated financial statements. The Company adopted Accounting standard codification (ASC) Topic 606, Revenue from Contracts with Customers (“Topic 606”), effective January 1, 2018. The revenue accounting policy followed by the company before its adoption of Topic 606 is described below. 2. Summary of significant accounting policies (Continued) The Company derives its revenue primarily from business process outsourcing and information technology services, which are provided on a time-and-material, transaction or fixed-price basis. The Company recognizes revenue when persuasive evidence of an arrangement exists, the sales price is fixed or determinable, services have been rendered and collectability is reasonably assured. Revenues from services rendered under time-and-materials and transaction-based contracts are recognized as the services are provided. The Company’s fixed-price contracts include contracts for application development, maintenance and support services. Revenues from these contracts are recognized ratably over the term of the agreement. The Company accrues for revenue and unbilled receivables for the services rendered between the last billing date and the balance sheet date. Customer contracts can also include incentive payments received for discrete benefits delivered to clients. Revenues relating to such incentive payments are recorded when the contingency is satisfied and the Company concludes the amounts are earned. Revenue from fixed-price contracts for the development of software and related services is recognized in accordance with the percentage-of-completion method. Guidance has been drawn from Financial Accounting Standards Board (“FASB”) guidance on Software—Revenue Recognition to account for revenue from fixed-price arrangements for software development and related services in conformity with FASB guidance on Revenue Recognition—Construction—Type and Production-Type Contracts. The input (effort or cost expended) method has been used to measure progress towards completion as there is a direct relationship between input and productivity. Provisions for estimated losses, if any, on uncompleted contracts are recorded in the period in which such losses become probable based on the current contract estimates. The Company has deferred the revenue and costs attributable to certain process transition activities with respect to its customers where such activities do not represent the culmination of a separate earnings process. Such revenue and costs are subsequently recognized ratably over the period in which the related services are performed. Further, the deferred costs are limited to the amount of the deferred revenues. Revenues are reported net of value-added tax, business tax and applicable discounts and allowances. Reimbursements of out-of-pocket expenses received from clients have been included as part of revenues. The Company enters into multiple-element revenue arrangements in which a client may purchase a combination of its services. Revenue from multiple-element arrangements is recognized, for each element, based on (1) the attainment of the delivery criterion; (2) its fair value, which is determined using the selling price hierarchy of vendor-specific objective evidence (“VSOE”) of fair value, third-party evidence or best estimated selling price, as applicable, and (3) its allocated selling price, which is based on the relative sales price method. The Company has changed its accounting policy for revenue recognition as detailed below. The Company applied Topic 606 using the modified retrospective method, which involves recognizing the cumulative effect of initially applying Topic 606 as an adjustment to the Company’s opening equity balance as of January 1, 2018. Therefore, comparative information has not been adjusted and continues to be reported under Topic 605. As a result of the Company’s adoption of this new standard, certain sales incentive programs meet the requirements for capitalization. Such costs are amortized over the period of expected benefit rather than being expensed as incurred as was the Company’s prior practice. The cumulative impact of the adoption of this standard 2. Summary of significant accounting policies (Continued) resulted in an increase in retained earnings of $17,924 as of January 1, 2018 with a corresponding impact on contract cost assets of $23,227 and deferred tax liabilities of $5,303 . As of January 1, 2018, contract assets and contract liabilities of $21,348 relating to the same customer contracts have been offset against each other. (d) Revenue recognition (effective January 1, 2018) The Company derives its revenue primarily from business process outsourcing and information technology services, which are provided primarily on a time-and-material, transaction or fixed-price basis. The Company recognizes revenue when the promised services are delivered to customers for an amount that reflects the consideration to which the Company expects to be entitled in exchange for those services. Revenues from services rendered under time-and-material and transaction-based contracts are recognized as the services are provided. The Company’s fixed-price contracts include contracts for application development, maintenance and support services. Revenues from these contracts are recognized ratably over the term of the agreement. The Company accrues for revenue and unbilled receivables for services rendered between the last billing date and the balance sheet date. The Company’s customer contracts sometimes also include incentive payments received for discrete benefits delivered or promised to be delivered to clients or service level agreements that could result in credits or refunds to the client. Revenues relating to such arrangements are accounted for as variable consideration when the amount of revenue to be recognized can be estimated to the extent that it is probable that a significant reversal of any incremental revenue will not occur The Company records deferred revenue attributable to certain process transition activities where such activities do not represent separate performance obligations. Revenues relating to such transition activities are classified under contract liabilities and subsequently recognized ratably over the period in which the related services are performed. Costs relating to such transition activities are fulfillment costs which are directly related to the contract and result in the generation or enhancement of resources. Such costs are expected to be recoverable under the contract and are therefore classified as contract cost assets and recognized ratably over the estimated expected period of benefit under cost of revenue. Revenues are reported net of value-added tax, business tax and applicable discounts and allowances. Reimbursements of out-of-pocket expenses received from clients have been included as part of revenues. Revenue for performance obligations that are satisfied over time is recognized in accordance with the methods prescribed for measuring progress. The input (effort or cost expended) method has been used to measure progress towards completion as there is a direct relationship between input and productivity. Provisions for estimated losses, if any, on uncompleted contracts are recorded in the period in which such losses become probable based on the current contract estimates. The Company enters into multiple-element revenue arrangements in which a client may purchase a combination of products or services. Revenue from multiple-element arrangements is recognized, for each element, based on an allocation of the transaction price to each performance obligation on a relative standalone basis. Certain contracts may include offerings such as sale of licenses, which may be perpetual or subscription-based. Revenue from distinct perpetual licenses is recognized upfront at the point in time when the software is made available to the customer. Revenue from distinct subscription-based licenses is recognized at the point in time it is transferred to the client. Revenue from any associated maintenance or ongoing support services is recognized ratably over the term of the contract. For a combined software license/services performance obligation, revenue is recognized over the period that the services are performed. 2. Summary of significant accounting policies (Continued) All incremental and direct costs incurred for acquiring contracts, such as certain sales commissions, are classified as contract cost assets. Such costs are amortized over the expected period of benefit and recorded under selling, general and administrative expenses. Other upfront fees paid to clients are classified as contract assets. Such costs are amortized over the expected period of benefit and recorded as an adjustment to the transaction price and subtracted from revenue. Timing of revenue recognition may differ from the timing of invoicing. If a payment is received in respect of services prior to the delivery of services, the payment is recognized as an advance from clients and classified as a contract liability. Contract assets and contract liabilities relating to the same client contract are offset against each other and presented on a net basis in the consolidated financial statements. See note 27 for information and related disclosures regarding contract balances. Significant judgements The Company often enters into contracts with clients that include promises to transfer multiple products and services to the client. Determining whether products and services are considered distinct performance obligations that should be accounted for separately rather than together may require significant judgment. Judgment is also required to determine the standalone selling price for each distinct performance obligation. In instances where the standalone selling price is not directly observable, it is determined using information that may include market conditions and other observable inputs. Client contracts sometimes include incentive payments received for discrete benefits delivered to clients or service level agreements that could result in credits or refunds to the client. Such amounts are estimated at contract inception and are adjusted at the end of each reporting period as additional information becomes available only to the extent that it is probable that a significant reversal of any incremental revenue will not occur. 2. Summary of significant accounting policies (Continued) Impact on consolidated financial statements The following tables summarize the impact of the Company’s adoption of Topic 606 on its consolidated financial statements for the year ended December 31, 2018.

(b) The cumulative impact of the adoption of ASC 606 resulted in a $160,193 increase in "Contract cost assets," which includes the reclassification of $134,302 (refer to note a in the table above) and a closing balance of $25,891 related to sales incentive programs, with a corresponding impact on retained earnings of $ 19,907 and on deferred tax assets of $5,984 which has been offset against deferred tax assets. (c) As a result of its adoption of ASC 606, the company has offset contract assets amounting to $7,890 under “Prepaid expenses and other current assets” and $21,535 under “Other assets” against contract liabilities amounting $10,289 under “Accrued expenses and other current liabilities” and $19,136 under “Other liabilities” related to the same customer contract. 2.

Following the adoption of ASC 606, the Company capitalized such costs in an amount of $17,452, resulting in a net adjustment of $2,664 and a tax impact of $(681) which is further adjusted by note (g) below. (g) Following the adoption of ASC 606, the Company offset certain contract assets against contract liabilities related to the same client contract in an amount of $8,077. 2. Summary of significant accounting policies (Continued) (e) Accounts receivable Accounts receivable are recorded at the invoiced or to be invoiced amount and do not bear interest. Amounts collected on trade accounts receivable are included in net cash provided by operating activities in the consolidated statements of cash flows. The Company maintains an allowance for doubtful accounts for estimated losses inherent in its accounts receivable portfolio. In establishing the required allowance, management considers historical losses adjusted to take into account current market conditions and clients’ financial conditions, the amount of receivables in dispute, and the current receivables’ aging and current payment patterns. Account balances are charged off against the allowance after all means of collection have been exhausted and the potential for recovery is considered remote. The Company does not have any off-balance-sheet credit exposure related to its clients. (f) Cash and cash equivalents Cash and cash equivalents consist of cash and bank balances and all highly liquid investments purchased with an original maturity of three months or less. (g) Short-term investments All liquid investments with an original maturity greater than 90 days but less than one year are considered to be short-term investments. Marketable short-term investments are classified and accounted for as available-for-sale investments. Available-for-sale investments are reported at fair value with changes in unrealized gains and losses recorded as a separate component of other comprehensive income (loss) until realized. Realized gains and losses on investments are determined based on the specific identification method and are included in “Other income (expense), net.” The Company does not hold these investments for speculative purposes. (h) Property, plant and equipment, net Property, plant and equipment are stated at cost less accumulated depreciation and amortization. Expenditures for replacements and improvements are capitalized, whereas the costs of maintenance and repairs are charged to earnings as incurred. The Company depreciates and amortizes all property, plant and equipment using the straight-line method over the following estimated economic useful lives of the assets: Years Buildings 40 Furniture and fixtures 4 Computer equipment and servers 4 Plant, machinery and equipment 4 Computer software 4-7 Leasehold improvements Lesser of lease period or 10 Years Vehicles 3-4 The Company capitalizes certain computer software and software development costs incurred in connection with developing or obtaining computer software for internal use when both the preliminary project stage is completed and it is probable that the software will be used as intended. Capitalized software costs include only (i) external direct costs of materials and services utilized in developing or obtaining computer software, (ii) compensation and related benefits for employees who are directly associated with the software project, and (iii) interest costs incurred while developing internal-use computer software. 2. Summary of significant accounting policies (Continued) Capitalized computer software costs are included in property, plant and equipment on the Company’s balance sheet and amortized on a straight-line basis when placed into service over the estimated useful lives of the software. Advances paid towards acquisition of property, plant and equipment outstanding as of each balance sheet date and the cost of property, plant and equipment not put to use before such date are disclosed under “Capital work in progress.” (i) Business combinations, goodwill and other intangible assets The Company accounts for its business combinations using the acquisition method of accounting in accordance with ASC 805, Business Combinations, by recognizing the identifiable tangible and intangible assets acquired and liabilities assumed, and any non-controlling interest in the acquired business, measured at their acquisition date fair values. Contingent consideration is included within the acquisition cost and is recognized at its fair value on the acquisition date. A liability resulting from contingent consideration is remeasured to fair value as of each reporting date until the contingency is resolved. Changes in fair value are recognized in earnings. All assets and liabilities of the acquired businesses, including goodwill, are assigned to reporting units. Acquisition-related costs are expensed as incurred under Selling, General and Administrative Expenses. Goodwill represents the cost of acquired businesses in excess of the fair value of identifiable tangible and intangible net assets purchased. Goodwill is not amortized but is tested for impairment at least on an annual basis on December 31, based on a number of factors, including operating results, business plans and future cash flows. The Company performs an assessment of qualitative factors to determine whether the existence of events or circumstances leads to a determination that it is more likely than not that the fair value of a reporting unit is less than its carrying amount. Based on the assessment of events or circumstances, the Company performs a quantitative assessment of goodwill impairment if it determines that it is more likely than not that the fair value of a reporting unit is less than its carrying amount. If, based on the quantitative impairment analysis, the carrying value of the goodwill of a reporting unit exceeds the fair value of such goodwill, an impairment loss is recognized in an amount equal to the excess. In addition, the Company performs a qualitative assessment of goodwill impairment between annual tests if an event occurs or circumstances change that would more likely than not reduce the fair value of a reporting unit below its carrying amount. See Note 10 for information and related disclosures. Intangible assets including technology acquired / developed individually or with a group of other assets or in a business combination are carried at cost less accumulated amortization based on their estimated useful lives as follows: Customer-related intangible assets 1-14 years Marketing-related intangible assets 1-10 years Technology-related intangible assets 2-8 years Other intangible assets 3-5 years Intangible assets are amortized over their estimated useful lives using a method of amortization that reflects the pattern in which the economic benefits of the intangible assets are consumed or otherwise realized. In business combinations, where the fair value of identifiable tangible and intangible net assets purchased exceeds the cost of the acquired business, the Company recognizes the resulting gain under “Other operating (income) expense, net” in the Consolidated Statements of Income. 2. Summary of significant accounting policies (Continued) The Company also capitalizes certain software and technology development costs incurred in connection with developing or obtaining software or technology for sale/lease to customers when the initial design phase is completed and commercial and technological feasibility has been established. Any development cost incurred before technological feasibility is established is expensed as incurred as research and development costs. Technological feasibility is established upon completion of a detailed design program or, in its absence, completion of a working model. Capitalized software and technology costs include only (i) external direct costs of materials and services utilized in developing or obtaining software and technology and (ii) compensation and related benefits for employees who are directly associated with the project. Costs incurred in connection with developing or obtaining software or technology for sale/lease to customers which are under development and not put to use are disclosed under “intangible assets under development.” Advances paid toward the acquisition of intangible assets outstanding as of each balance sheet date are disclosed under “intangible assets under development.” Capitalized software and technology costs are included in intangible assets under technology-related intangible assets on the Company’s balance sheet and amortized on a straight-line basis when placed into service over the estimated useful lives of the software and technology. (j) Impairment of long-lived assets Long-lived assets, including certain intangible assets, to be held and used are reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount of such assets may not be recoverable. Such assets are required to be tested for impairment if the carrying amount of the assets is higher than the future undiscounted net cash flows expected to be generated from the assets. The impairment amount to be recognized is measured as the amount by which the carrying value of the assets exceeds their fair value. The Company determines fair value by using a discounted cash flow approach. (k) Foreign currency The Company’s consolidated financial statements are reported in U.S. dollars, the Company’s functional currency. The functional currency for the Company’s subsidiaries organized in Europe, other than the United Kingdom, the Czech Republic, Luxembourg and one subsidiary in Poland, is the euro, and the functional currencies of the Company’s subsidiaries organized in Brazil, China, Colombia, Guatemala, India, Israel, Japan, Morocco, South Africa, the Philippines, Poland, the Czech Republic, Hong Kong, Singapore, Australia and Canada are their respective local currencies.

The fair value measurements of these financial assets and liabilities were determined using the following inputs as of December 31, 2017 and 2018: As of December 31, 2017 Fair Value Measurements at Reporting Date Using Quoted Prices in Active Markets for Identical Assets Significant Other Observable Inputs Significant Other Unobservable Inputs Total (Level 1) (Level 2) (Level 3) Assets Derivative instruments (Note a, c) $ 73,098 $ — $ 73,098 $ — Total $ 73,098 $ — $ 73,098 $ — Liabilities Earn out consideration (Note b, d) $ 24,732 $ — $ — $ 24,732 Derivative instruments (Note b, c) $ 18,188 $ — $ 18,188 $ — Total $ 42,920 $ — $ 18,188 $ 24,732 Redeemable non-controlling interest (Note e) $ 4,750 $ — $ — $ 4,750 As of December 31 2018 Fair Value Measurements at Reporting Date Using Quoted Prices in Active Markets for Identical Assets Significant Other Observable Inputs Significant Other Unobservable Inputs Total (Level 1) (Level 2) (Level 3) Assets Derivative instruments (Note a, c) $ 44,099 $ — $ 44,099 $ — Deferred compensation plan assets (a, f) 1,613 — — 1,613 Total $ 45,712 $ — $ 44,099 $ 1,613 Liabilities Earn-out consideration (Note b, d) $ 17,073 $ — $ — $ 17,073 Derivative instruments (Note b, c) 35,245 — 35,245 — Deferred compensation plan liability (b, g) 1,582 — — 1,582 Total $ 53,900 $ — $ 35,245 $ 18,655 (a) Included in “prepaid expenses and other current assets” and “other assets” in the consolidated balance sheets. (b) Included in “accrued expenses and other current liabilities” and “other liabilities” in the consolidated balance sheets. (c) The Company values its derivative instruments based on market observable inputs, including both forward and spot prices for the relevant currencies and interest rate indices for relevant interest rates. The quotes are taken from an independent market database. (d) The fair value of earn-out consideration, calculated as the present value of expected future payments to be made to the sellers of acquired businesses, was derived by estimating the future financial performance of the acquired businesses using the earn-out formula and performance targets specified in each purchase agreement and adjusting the result to reflect the Company’s estimate of the likelihood of achievement of such targets. Given the significance of the unobservable inputs, the valuations are classified in level 3 of the fair value hierarchy. (e) The Company’s estimate of the fair value of redeemable non-controlling interest as of December 31, 2017 is based on unobservable inputs considering the assumptions that market participants would make in pricing the obligation. Given the significance of the unobservable inputs, the valuation was classified in level 3 of the fair value hierarchy. Refer to Note 3—Business Acquisitions. (f) Deferred compensation plan assets consist of life insurance policies held under a Rabbi Trust. Assets held in the Rabbi Trust are valued based on the cash surrender value of the insurance contract, which is determined based on the fair value of the underlying assets included in the insurance portfolio and are therefore classified within level 3 of the valuation hierarchy. 6. Fair Value Measurements (Continued) (g) The fair value of the deferred compensation plan liability is derived based on the fair value of the underlying assets in the insurance policies and is therefore classified within level 3 of the valuation hierarchy .

Derivative Instruments And Hedging Activities Disclosure [Abstract]
Derivative financial instruments	7. Derivative financial instruments The Company is exposed to the risk of rate fluctuations on foreign currency assets and liabilities and on foreign currency denominated forecasted cash flows. The Company has established risk management policies, including the use of derivative financial instruments to hedge foreign currency assets and liabilities and foreign currency denominated forecasted cash flows and interest rate risks. These derivative financial instruments are largely deliverable and non-deliverable forward foreign exchange contracts and interest rate swaps. The Company enters into these contracts with counterparties that are banks or other financial institutions, and the Company considers the risk of non-performance by such counterparties not to be material. The forward foreign exchange contracts and interest rate swaps mature over periods of up to 60 months and the forecasted transactions are expected to occur during the same periods. The following table presents the aggregate notional principal amounts of outstanding derivative financial instruments together with the related balance sheet exposure: Notional principal amounts (note a) Balance sheet exposure asset (liability) (note b) As of December 31, 2017 As of December 31, 2018 As of December 31, 2017 As of December 31, 2018 Foreign exchange forward contracts denominated in: United States Dollars (sell) Indian Rupees (buy) $ 1,289,400 $ 1,439,000 $ 54,398 $ (3,643 ) United States Dollars (sell) Mexican Peso (buy) 9,000 — (441 ) — United States Dollars (sell) Philippines Peso (buy) 76,650 55,800 69 (1,510 ) Euro (sell) United States Dollars (buy) 170,542 136,412 (2,069 ) 4,804 Pound Sterling (buy) United States Dollars (sell) 24,041 128 253 (128 ) Euro (sell) Romanian Leu (buy) 35,826 41,198 (892 ) (299 ) Japanese Yen (sell) Chinese Renminbi (buy) 60,768 40,568 1,918 (2,195 ) Pound Sterling (sell) United States Dollars (buy) 80,871 27,517 (2,478 ) 495 Australian Dollars (sell) United States Dollars (buy) 136,092 89,780 (5,180 ) 3,548 Interest rate swaps (floating to fixed) 432,117 507,425 9,332 7,782 54,910 8,854 (a) Notional amounts are key elements of derivative financial instrument agreements but do not represent the amount exchanged by counterparties and do not measure the Company’s exposure to credit, foreign exchange, interest rate or other market risks. However, the amounts exchanged are based on the notional amounts and other provisions of the underlying derivative financial instrument agreements. (b) Balance sheet exposure is denominated in U.S. dollars and denotes the mark-to-market impact of the derivative financial instruments on the reporting date. FASB guidance on derivatives and hedging requires companies to recognize all derivative instruments as either assets or liabilities at fair value in the balance sheet. In accordance with the FASB guidance on derivatives and hedging, the Company designates foreign exchange forward contracts and interest rate swaps as cash flow hedges. Foreign exchange forward contracts are entered into to cover the effects of future exchange rate variability on forecasted revenue and purchases of services, and interest rate swaps are entered into to cover interest rate fluctuation risk. In addition to this program, the Company uses derivative instruments that are not accounted for as hedges under the FASB guidance in order to hedge foreign exchange risks related to balance sheet items, such as receivables and intercompany borrowings, that are denominated in currencies other than the Company’s underlying functional currency. 7.

Long-term debt In August 2018, the Company amended its 2015 credit facility (“the 2015 Facility”), which was comprised of an $800,000 term loan and a $350,000 revolving credit facility. The amended facility (the “2018 Facility”) is comprised of a $680,000 term loan, which represents the outstanding balance under the 2015 Facility as of the date of amendment, and a $500,000 revolving credit facility. The 2018 Facility expires on August 8, 2023. The amendment did not result in a substantial modification of $550,814 of the outstanding term loan under the 2015 Facility. Further, as a result of the amendment, the Company extinguished the outstanding term loan under the 2015 Facility of $129,186 and obtained additional funding of $129,186, resulting in no change to the outstanding principal of the term loan under the 2018 Facility. In connection with the amendment, the Company expensed $2,029, representing partial acceleration of the amortization of the existing unamortized debt issuance costs and an additional fee paid to the Company’s lenders related to the term loan. The overall borrowing capacity under the revolving credit facility increased from $350,000 to $500,000. The amendment of the revolving credit facility resulted in accelerated amortization of $82 relating to existing unamortized debt issuance cost. The remaining unamortized costs and an additional third party fee paid in connection with the amendment will be amortized over the term of the amended facility, which will expire on August 8, 2023. . Borrowings under the 2018 Facility bear interest at a rate equal to, at the election of the Company, either LIBOR plus an applicable margin equal to 1.375% per annum, compared to a margin of 1.50% under the 2015 facility, or a base rate plus an applicable margin equal to 0.375% per annum, compared to a margin of 0.50% under the 2015 facility, in each case subject to adjustment based on the Company’s debt ratings provided by Standard & Poor’s Rating Services and Moody’s Investors Service, Inc. Based on the Company’s election and current credit rating, the applicable interest rate is equal to LIBOR plus 1.375% per annum. The amended credit agreement contains certain customary covenants, including a maximum leverage covenant and a minimum interest coverage ratio. During the year ended December 31, 2018, the Company was in compliance with the financial covenants. 14.

Indebtedness under the 2018 Facility is unsecured. The amount outstanding on the term loan as of December 31, 2018 requires quarterly payments of $8,500, and the balance of the loan is due and payable upon the maturity of the term loan on Aug 8, 2023. The maturity profile of the term loan outstanding as of December 31, 2018, net of debt amortization expense, is as follows: Year ended Amount 2019 $ 33,483 2020 33,509 2021 33,537 2022 33,564 2023 526,748 Total $ 660,841 In March 2017, Genpact Luxembourg S.à.r.l.

The Issuer will pay interest on the notes semi-annually in arrears on April 1 and October 1 of each year, ending on the maturity date of April 1, 2022. The Company, at its option, may redeem the notes at any time in whole or in part, at a redemption price equal to (i) 100% of the principal amount of the notes redeemed, together with accrued and unpaid interest on the redeemed amount, and (ii) if the notes are redeemed prior to March 1, 2022, a specified “make-whole” premium. The notes are subject to certain customary covenants, including limitations on the ability of the Company and certain of its subsidiaries to incur debt secured by liens, engage in certain sale and leaseback transactions and consolidate, merge, convey or transfer their assets, and during the year ended December 31, 2018, the Company and its applicable subsidiaries were in compliance with the covenants. Upon certain change of control transactions, the Issuer will be required to make an offer to repurchase the notes at a price equal to 101% of the aggregate principal amount of such notes, plus accrued and unpaid interest. The interest rate payable on the notes is subject to adjustment if the credit rating of the notes is downgraded, up to a maximum increase of 2.0%. In connection with the 3.70% senior notes private offering, the Issuer and the Company entered into a registration rights agreement with the initial purchasers of the outstanding unregistered notes pursuant to which the Issuer and the Company agreed to complete an exchange offer within 455 days after the date of the private offering upon terms identical in all material respects to the terms of the outstanding unregistered notes, except that the transfer restrictions, registration rights and additional interest provisions applicable to the outstanding unregistered notes would not apply to the exchange notes.

During the years ended December 31, 2016, 2017 and 2018, all of the plan assets were primarily invested in debt securities. In addition, in accordance with Mexican law, the Company provides certain termination benefits (the “Mexican Plan”) to all of its Mexican employees based on the age, duration of service and salary of each eligible employee. The full-year benefit cost of the Mexican Plan is calculated on an actuarial basis. In addition, certain of the Company’s subsidiaries organized or operating in the Philippines and Japan have sponsored defined benefit retirement programs (respectively, the “Philippines Plan” and the “Japan Plan”). The full-year benefit costs of the Japan Plan and the Philippines Plan are calculated on an actuarial basis. Company contributions in respect of these plans are made to insurer-managed funds or to a trust. The trust contributions are further invested in government bonds. In addition, in accordance with Israeli law, the Company provides certain termination benefits (the “Israeli Plan”) to all of its Israeli employees based on the age, duration of service and salary of each eligible employee. The full-year benefit cost of the Israeli Plan is calculated on an actuarial basis. Current service costs for defined benefit plans are accrued in the year to which they relate on a monthly basis. Actuarial gains or losses, or prior service costs, if any, resulting from amendments to the plans are recognized and amortized over the remaining period of service of the employees or over the average remaining life expectancies for inactive employees if most of the plan obligations are payable to inactive employees. 17.

The Plan provides a select group of U.S.-based members of Company management with the opportunity to defer from 1% to 80% of their base salary and from 1% to 100% of their qualifying bonus compensation (or such other minimums or maximums as determined by the Plan administrator from time to time) pursuant to the terms of the Plan. Participant deferrals are 100% vested at all times. The Plan also allows for discretionary supplemental employer contributions by the Company, in its sole discretion, which will be subject to a two-year vesting schedule (50% vesting on the one-year anniversary of approval of the contribution and 50% vesting on the second year anniversary of approval of the contribution) or such other vesting schedule as determined by the Company. Deferred compensation plan assets consist of life insurance policies. In December 2018, the Company transferred these policies to a Rabbi Trust, which now holds the assets under the Plan. The Plan also provides an option for participants to elect to receive deferred compensation and earnings thereon on either fixed date(s) no earlier than two years following the applicable Plan year (or end of the applicable performance period for performance-based bonus compensation) or following a separation from service, in each case either in a lump sum or in annual installments over a term of up to 15 years. Each Plan participant’s compensation deferrals and discretionary supplemental employer contributions (if any) will be credited or debited with notional investment gains and losses equal to the experience of selected hypothetical investment funds offered under the Plan and elected by the participant. The Company has investments in funds held in Company-owned life insurance policies which are held in a Rabbi Trust that are classified as trading securities. Management determines the appropriate classification of the securities at the time they are acquired and evaluates the appropriateness of such classifications at each balance sheet date. The securities are classified as trading securities because they are held for resale in anticipation of short-term fluctuations in market prices. The trading securities are stated at fair value. 17. Employee benefit plans (Continued) The liability for the deferred compensation plan was $0 and $1,582 as of December 31, 2017 and December 31, 2018, respectively, and is included in “other liabilities” in the consolidated balance sheets. In connection with the administration of the Plan, the Company has purchased company-owned life insurance policies insuring the lives of certain employees. The cash surrender value of these policies was $0 and $1,613 as of December 31, 2017 and December 31, 2018, respectively. The cash surrender value of these insurance policies is included in “other assets” in the consolidated balance sheets. During the years ended December 31, 2017 and 2018, the change in the fair value of Plan assets was $0 and $(56), respectively, which is included in “other income (expense), net,” in the consolidated statements of income. During the year ended December 31, 2017 and 2018, the change in the fair value of deferred compensation liabilities was $0 and $(87), respectively, which is included in “selling, general and administrative expenses.

Disclosure Of Compensation Related Costs Sharebased Payments [Abstract]
Stock-based compensation	18. Stock-based compensation The Company has issued options under the Genpact Limited 2007 Omnibus Incentive Compensation Plan (the “2007 Omnibus Plan”) and the Genpact Limited 2017 Omnibus Incentive Compensation Plan (the “2017 Omnibus Plan”) to eligible persons, including employees, directors and certain other persons associated with the Company. Under the 2007 Omnibus Plan, shares underlying options forfeited, expired, terminated or cancelled under any of the Company’s predecessor plans were added to the number of shares otherwise available for grant under the 2007 Omnibus Plan. The 2007 Omnibus Plan was amended and restated on April 11, 2012 to increase the number of common shares authorized for issuance by 5,593,200 shares to 15,000,000 shares. During the year ended December 31, 2012, the number of common shares authorized for issuance under the 2007 Omnibus Plan was increased by 8,858,823 shares as a result of a one-time adjustment to outstanding unvested share awards in connection with a special dividend payment. A brief summary of each plan is provided below: 2007 Omnibus Plan The Company adopted the 2007 Omnibus Plan on July 13, 2007 and amended and restated it on April 11, 2012. The 2007 Omnibus Plan provided for the grant of awards intended to qualify as incentive stock options, non-qualified stock options, share appreciation rights, restricted share awards, restricted share units, performance units, cash incentive awards and other equity-based or equity-related awards. Under the 2007 Omnibus Plan, the Company was authorized to grant awards for the issuance of up to a total of 23,858,823 common shares. 2017 Omnibus Plan On May 9, 2017, the Company’s shareholders approved the adoption of the Genpact Limited 2017 Omnibus Incentive Compensation Plan (the “2017 Omnibus Plan”), pursuant to which 15,000,000 Company common shares are available for issuance. No grants may be made under the 2007 Omnibus Plan after the date of adoption of the 2017 Omnibus Plan. Grants that were outstanding under the 2007 Omnibus Plan as of the Company’s adoption of the 2017 Omnibus Plan remain subject to the terms of the 2007 Omnibus Plan. Stock-based compensation costs relating to the foregoing plans during the years ended December 31, 2016, 2017 and 2018, were $24,686, $35,112 and $48,196, respectively, and have been allocated to cost of revenue and selling, general, and administrative expenses. Stock options All options granted under the 2007 and 2017 Omnibus Plans are exercisable into common shares of the Company, have a contractual period of ten years and vest over four to five years unless specified otherwise in the applicable award agreement. The Company recognizes compensation cost over the vesting period of the option. 18. Stock-based compensation (Continued) Compensation cost is determined at the date of grant by estimating the fair value of an option using the Black-Scholes option-pricing model. The following table shows the significant assumptions used in connection with the determination of the fair value of options granted in 2016, 2017 and 2018: 2016 2017 2018 Dividend yield — 0.97% 0.95%-1.01% Expected life (in months) 84 84 84 Risk-free rate of interest for expected life 1.42% - 1.56% 2.25 % 2.67 %-2.93% Volatility 25.60% - 27.22% 24.28% 22.55-22.73% Volatility was calculated based on the historical volatility of the Company’s share price during a period equivalent to the estimated term of the option. The Company estimates the expected term of an option using the “simplified method,” which is based on the average of its contractual vesting term. The risk-free interest rate that the Company uses in the option valuation model is based on U.S. Treasury bonds with a term similar to the expected term of the options. The Company paid cash dividends of $0.06 and $0.075 per share in each quarter of fiscal 2017 and 2018, respectively. The Company has issued, and intends to continue to issue, new common shares upon stock option exercises and the vesting of share awards under its equity-based incentive compensation plans. A summary of stock option activity during the years ended December 31, 2016, 2017 and 2018 is set out below: Year ended December 31, 2016 Shares arising out of options Weighted average exercise price Weighted average remaining contractual life (years) Aggregate intrinsic value Outstanding as of January 1, 2016 5,986,845 $ 16.99 5.8 $ — Granted 860,000 26.80 — — Forfeited (145,000 ) 17.77 — — Expired — — — — Exercised (994,155 ) 14.98 — 10,982 Outstanding as of December 31, 2016 5,707,690 $ 18.65 5.8 $ 34,641 Vested as of December 31, 2016 and expected to vest thereafter (Note a) 5,457,701 $ 18.42 5.8 $ 34,150 Vested and exercisable as of December 31, 2016 2,746,191 $ 15.62 4.0 $ 23,960 Weighted average grant-date fair value of options granted during the period $ 8.50 18.

Cash received by the Company upon the exercise of stock options amounted to $13,564, $14,896 and $10,772. Tax benefits from the exercise of stock options during the years ended December 31, 2016, 2017 and 2018 were $1,548 and $2,016 and $2,473 (including excess tax benefits of $1,004, $1,723 and $2,131), respectively. Income tax benefits recognized in relation to stock-based compensation charges, excluding excess tax benefits, during the years ended December 31, 2016, 2017 and 2018 were $6,446, $9,600 and $11,783, respectively. As of December 31, 2018, the total remaining unrecognized stock-based compensation cost for options expected to vest amounted to $21,925 which will be recognized over the weighted average remaining requisite vesting period of 4.0 years. Restricted Share Units The Company has granted restricted share units, or RSUs, under the 2007 and 2017 Omnibus Plans. Each RSU represents the right to receive one common share. The fair value of each RSU is the market price of one common share of the Company on the date of grant. The RSUs granted to date have graded vesting schedules of three months to four years. The compensation expense is recognized on a straight-line basis over the vesting term. 18.

(b) Vested RSUs were net settled by issuing 29,719 shares (net of minimum statutory tax withholding). 86,517 RSUs vested in the year ended December 31, 2016. 17,802 common shares underlying 34,035 of such RSUs were issued in 2017 after withholding shares to the extent of minimum statutory withholding taxes. 52,482 RSUs vested in the year ended December 31, 2016, in respect of which 52,055 shares were issued in 2018 after withholding shares to the extent of minimum statutory withholding taxes. (c) Vested RSUs were net settled by issuing 32,395 shares (net of minimum statutory tax withholding). (d) 261,260 RSUs that vested during the period were net settled upon vesting by issuing 175,505 shares (net of minimum statutory tax withholding). 52,875 and 44,562 RSUs vested in the year ended December 31, 2017 and December 31, 2018 respectively, shares in respect of which will be issuable in 2019 after withholding shares to the extent of minimum statutory withholding taxes. 53,546 RSUs vested in the year ended December 31, 2015, 53,023 shares in respect of which were issued in 2017 after withholding shares to the extent of minimum statutory withholding taxes. 92,692 RSUs vested in the year ended December 31, 2014, in respect of which 91,963 shares were issued in 2016 after withholding shares to the extent of minimum statutory withholding taxes. 18. Stock-based compensation (Continued) As of December 31, 2018, the total remaining unrecognized stock-based compensation cost related to RSUs amounted to $24,946, which will be recognized over the weighted average remaining requisite vesting period of 2.3 years. Performance Units The Company also grants stock awards in the form of performance units, or PUs, and has granted PUs under both the 2007 and 2017 Omnibus Plans. Each PU represents the right to receive one common share at a future date based on the Company’s performance against specified targets. PUs granted to date have vesting schedules of six months to three years. The fair value of each PU is the market price of one common share of the Company on the date of grant and assumes that performance targets will be achieved. PUs granted under the plan are subject to cliff vesting. The compensation expense for such awards is recognized on a straight-line basis over the vesting terms. During the performance period, the Company’s estimate of the number of shares to be issued is adjusted upward or downward based upon the probability of achievement of the performance targets.

As of December 31, 2018, the total remaining unrecognized stock-based compensation cost related to PUs amounted to $55,985, which will be recognized over the weighted average remaining requisite vesting period of 1.8 years. Employee Stock Purchase Plan (ESPP) On May 1, 2008, the Company adopted the Genpact Limited U.S. Employee Stock Purchase Plan and the Genpact Limited International Employee Stock Purchase Plan (together, the “ESPP”). In April 2018, these plans were amended and restated, and their terms were extended to August 31, 2028. The ESPP allows eligible employees to purchase the Company’s common shares through payroll deductions at 90% of the closing price of the Company’s common shares on the last business day of each purchase interval. The dollar amount of common shares purchased under the ESPP must not exceed 15% of the participating employee’s base salary, subject to a cap of $25 per employee per calendar year. With effect from September 1, 2009, the offering periods commence on the first business day in March, June, September and December of each year and end on the last business day of the subsequent May, August, November and February. 4,200,000 common shares have been reserved for issuance in the aggregate over the term of the ESPP. During the years ended December 31, 2016, 2017 and 2018, 146,685, 190,435 and 245,467 common shares, respectively, were issued under the ESPP. The ESPP is considered compensatory under FASB guidance on Compensation-Stock Compensation. The compensation expense for the ESPP is recognized in accordance with the FASB guidance on Compensation—Stock Compensation. The compensation expense for the ESPP during the years ended December 31, 2016, 2017 and 2018 was $428, $573 and $802, respectively, and has been allocated to cost of revenue and selling, general, and administrative expenses.

Equity [Abstract]
Capital stock	19. Capital stock The Company’s authorized capital stock as of December 31, 2017 and 2018 consisted of 500 million common shares with a par value of $0.01 per share, and 250 million preferred shares with a par value of $0.01 per share. There were 192,825,207 and 189,346,101 common shares, and no preferred shares, issued and outstanding as of December 31, 2017 and 2018, respectively. Holders of common shares are entitled to one vote per share. Upon the liquidation, dissolution or winding up of the Company, common shareholders are entitled to receive a ratable share of the available net assets of the Company after payment of all debts and other liabilities. The common shares have no preemptive, subscription, redemption or conversion rights. The Company’s board of directors by resolution can establish one or more series of preferred shares having such par value, designations, dividend rates, relative voting rights, conversion or exchange rights, redemption rights, liquidation rights and other relative participation, optional or other rights, qualifications, limitations or restrictions as may be fixed by the board of directors without shareholder approval. Such rights, preferences, powers and limitations as may be established could also have the effect of discouraging an attempt to obtain control of the Company. These preferred shares are of the type commonly known as “blank-check” preferred shares. Under Bermuda law, the Company may declare and pay dividends from time to time unless there are reasonable grounds for believing that the Company is or would, after the payment, be unable to pay its liabilities as they become due or that the realizable value of its assets would thereby be less than the aggregate of its liabilities, its issued share capital, and its share premium accounts. Under the Company’s bye-laws, each common share is entitled to dividends if, as and when dividends are declared by the Company’s board of directors. There are no restrictions in Bermuda on the Company’s ability to transfer funds (other than funds denominated in Bermuda dollars) in or out of Bermuda or to pay dividends to U.S. residents who are holders of common shares. The Company’s ability to declare and pay cash dividends is restricted by its debt covenants. Share Repurchases As of December 31, 2016, the Company’s board of directors (the “Board”) had authorized the Company to repurchase up to $750,000 in value of the Company’s common shares under its share repurchase program first announced in February 2015. On February 10, 2017 the Board approved up to an additional $500,000 in share repurchases, bringing the total authorization under the Company’s existing program to $1,250,000. The Company’s share repurchase program does not obligate it to acquire any specific number of shares. Under the program, shares may be purchased in privately negotiated and/or open market transactions, including under plans complying with Rule 10b5-1 under the Securities Exchange Act of 1934, as amended. On March 29, 2017, the Company entered into an accelerated share repurchase (“ASR”) agreement with Morgan Stanley & Co. LLC (the “Dealer”) to repurchase Company common shares for an aggregate purchase price of $200,000. Pursuant to the ASR agreement, as amended in November 2017, the Company paid the aggregate purchase price to the Dealer upfront and received an initial delivery of 6,578,947 common shares on March 30, 2017, an additional delivery of 350,006 common shares on December 29, 2017 and a final delivery of 163,975 common shares on January 17, 2018 upon final settlement of the transaction. The weighted average price per share of the common shares delivered was $28.20. The Company’s purchase of its common shares under the ASR has been recorded as a reduction in retained earnings. All repurchased shares have been retired. The final number of common shares repurchased by the Company under the ASR agreement was based on the volume-weighted average share price of the Company’s common shares during the term of the transaction, less a discount and subject to adjustments pursuant to the terms of the ASR agreement. The ASR agreement contains customary provisions, including, among other things, with respect to mechanisms to determine the number of shares or the amount of cash that will be delivered at settlement, the required timing of delivery upon settlement, specific circumstances under which adjustments may be made to the repurchase transaction, and specific circumstances under which the repurchase transaction may be canceled prior to the scheduled maturity. During the years ended December 31, 2018 and December 31, 2017, the Company also purchased 4,921,192 and 808,293 of its common shares, respectively, on the open market at a weighted average price of $31.30 and $24.48 per share, respectively, for an aggregate cash amount of $154,058 and $19,784, respectively. 19. Capital stock (Continued) The Company records repurchases of its common shares on the settlement date of each transaction. Shares purchased and retired are deducted to the extent of their par value from common stock and from retained earnings for the excess over par value. Direct costs incurred to acquire the shares are included in the total cost of the shares purchased. For the year ended December 31, 2016, December 31, 2017 and December 31, 2018, $279, $16 and $98, respectively, was deducted from retained earnings in direct costs related to share repurchases. Dividend In February 2017, the Company’s board of directors approved a dividend program under which the Company paid a regular quarterly cash dividend of $0.06 per share to holders of its common shares, representing an annual dividend of $0.24 per share. On March 28, 2017, June 28, 2017, September 21, 2017, and December On February 12, 2018, the Company announced that its Board of Directors had approved a 25% increase in its quarterly cash dividend to $0.075 per share, up from $0.06 per share in 2017, representing an annual dividend of $0.30 per common share, up from $0.24 per share in 2017, payable to holders of the Company’s common shares. On March 21, 2018, June 20, 2018, September 19, 2018 and December 19, 2018, the Company paid dividends of $0.075 per share, amounting to $14,408, $14,240, $14,253 and $14,201 in the aggregate, to shareholders of record as of March 9, 2018, June 8, 2018, September 10, 2018 and December 10, 2018, respectively.

Earnings Per Share [Abstract]
Earnings per share	20. Earnings per share The Company calculates earnings per share in accordance with FASB guidance on Earnings per Share. Basic and diluted earnings per common share give effect to the change in the number of common shares outstanding. The calculation of basic earnings per common share was determined by dividing net income available to common shareholders by the weighted average number of common shares outstanding. The potentially dilutive shares, consisting of outstanding options on common shares, restricted share units, common shares to be issued under the ESPP and performance units, have been included in the computation of diluted net earnings per share and number of weighted average shares outstanding, except where the result would be anti-dilutive. The number of stock awards outstanding but not included in the computation of diluted earnings per common share because their effect was anti-dilutive is 781,215, 1,007,480 and 2,410,230 for the years ended December 31, 2016, 2017 and 2018, respectively.

Income taxes (Continued) Income tax expense (benefit) attributable to income from continuing operations differed from the amounts computed by applying the U.S. federal statutory income tax rate of 21% for the year ended December 31, 2018 and 35% for the years ended December 31, 2017 and 2016 to income before income taxes, as a result of the following: Year ended December 31, 2016 2017 2018 Income before income tax expense $ 329,645 $ 320,583 $ 362,021 Statutory tax rates 35 % 35 % 21 % Computed expected income tax expense 115,376 112,204 76,024 Increase (decrease) in income taxes resulting from: Foreign tax rate differential (18,574 ) (25,224 ) 23,373 Tax benefit from tax holiday (32,893 ) (35,814 ) (24,968 ) Non-deductible expenses 4,559 3,985 3,245 Effect of change in tax rates 353 2,778 (147 ) Change in valuation allowance (4,830 ) 9,041 27,826 Unrecognized tax benefits (627 ) 1,611 3,008 Other* (1,266 ) (8,839 ) (27,598 ) Reported income tax expense (benefit) $ 62,098 $ 59,742 $ 80,763 *Following the transfer/closure of certain affiliated entities, deferred tax liabilities recorded against the outside basis difference were reversed amounting to $0, $9,600, $18,510 during the year ended December 31, 2016, 2017 and 2018. It was not more likely than not that the resulting net deferred tax asset would be realized. Therefore, a full valuation allowance was established to offset the reduction in deferred tax liabilities. A portion of the profits of the Company’s operations is exempt from income tax in India. One of the Company’s Indian subsidiaries has ten units eligible for a tax holiday as a special economic zone unit in respect of 100% of the export profits it generates for a period of 5 years from commencement, 50% of such profits for the next 5 years (year 6 to year 10 from commencement) and 50% of the profits for an additional period of 5 years (year 11 to year 15 from commencement), subject to the satisfaction of certain capital investment requirements. The tax holidays for the Company’s existing special economic zone units will begin to expire on March 31, 2022 and will have fully expired on March 31, 2030, assuming the Company satisfies the capital investment requirements. The effect of the Indian tax holiday on basic earnings per share was $0.19, $0.18 and $0.13, respectively, for the years ended December 31, 2016, 2017 and 2018. The effect of the tax holiday on diluted earnings per share was $0.18, $0.18 and $0.13, respectively, for the years ended December 31, 2016, 2017 and 2018. 25. Income taxes (Continued) The components of the Company’s deferred tax balances as of December 31, 2017 and 2018 are as follows: As of December 31, 2017 2018 Deferred tax assets Net operating loss carryforwards $ 55,500 $ 64,013 Accrued liabilities and other expenses 41,177 36,812 Provision for doubtful debts 10,509 9,650 Property, plant & equipment and leased assets 6,179 7,904 Unrealized losses on cash flow hedges, net 275 672 Share-based compensation 19,789 18,236 Retirement benefits 5,817 7,559 Contract liabilities 22,948 3,150 Tax credit carryforwards 35,322 22,409 Other 6,662 8,885 Gross deferred tax assets $ 204,178 $ 179,290 Less: Valuation allowance (24,549 ) (51,986 ) Total deferred tax assets $ 179,629 $ 127,304 Deferred tax liabilities Intangible assets $ 23,545 $ 17,975 Property, plant and equipment 1,131 5,493 Deferred cost 33,816 2,725 Investments in foreign subsidiaries not indefinitely reinvested 18,949 4,835 Unrealized gains on cash flow hedges, net 14,711 8,990 Goodwill 7,145 12,957 Other 10,150 7,843 Total deferred tax liabilities $ 109,447 $ 60,818 Net deferred tax asset $ 70,182 $ 66,486 As of December 31, Classified as 2017 2018 Deferred tax assets Non-current $ 76,929 $ 74,566 Deferred tax liabilities Non-current 6,747 8,080 $ 70,182 $ 66,486 The change in the total valuation allowance for deferred tax assets as of December 31, 2016, 2017 and 2018 is as follows: Year ended December 31, 2016 2017 2018 Opening valuation allowance $ 20,091 $ 14,746 $ 24,549 Reduction during the year (7,299 ) (3,957 ) (2,307 ) Addition during the year 1,954 13,760 29,744 Closing valuation allowance $ 14,746 $ 24,549 $ 51,986 25. Income taxes (Continued) In assessing the realizability of deferred tax assets, management considers whether it is more likely than not that some or all of the deferred tax assets will not be realized. The ultimate realization of deferred tax assets depends on the generation of future taxable income during the periods in which temporary differences are deductible. Management considers the scheduled reversal of deferred tax liabilities and projected taxable income in making this assessment. In order to fully realize a deferred tax asset, the Company must generate future taxable income prior to the expiration of the deferred tax asset under applicable law. Based on the level of historical taxable income and projections for future taxable income over the periods during which the Company’s deferred tax assets are deductible, management believes that it is more likely than not that the Company will realize the benefits of these deductible differences, net of the existing valuation allowances as of December 31, 2018. The amount of the Company’s deferred tax assets considered realizable, however, could be reduced in the near term if estimates of future taxable income during the carryforward period are reduced. In 2016, one of the Company’s subsidiaries filed amended tax returns with respect to prior years, resulting in revised assessments, higher taxable income and the utilization of operating loss carryforwards. The use of operating loss carryforwards resulted in the complete reversal of the subsidiary’s remaining valuation allowance of $3,377. On January 1, 2016, the Company elected the early adoption of ASU 2016-09, which was applied using a modified retrospective approach. Accordingly, excess tax benefits relating to the exercise of stock options prior to December 31, 2015 amounting to $24,912 were recorded through retained earnings. For the years ended December 31, 2016 and 2017 and 2018, the Company recognized net excess tax benefits of $1,004, $1,723 and $2,131 in income tax expense attributable to continuing operations. As of December 31, 2018, the Company’s deferred tax assets related to net operating loss carryforwards of $276,040 amounted to $59,153 (excluding state net operating losses). Net operating losses of subsidiaries in the United Kingdom, Singapore, Malaysia, Australia, Brazil, Israel, South Africa, Hong Kong, Germany, the United States (for 2018) and Luxembourg (for 2016 and prior years) amounted to $164,014 and can be carried forward for an indefinite period. 25.

As of December 31, 2018, the Company had additional deferred tax assets for U.S. state and local tax loss carryforwards amounting to $4,859 with varying expiration periods between 2019 and 2037. As of December 31, 2018, the company had a total foreign tax credit carryforward of $22,409, which will expire as set forth in the table below: Year ending December 31, Amount 2023 355 2024 2,819 2025 8,395 2026 5,728 2027 1,250 2028 3,862 $ 22,409 With exceptions, the Company has not accrued any income, distribution or withholding taxes that would arise if the undistributed earnings of the Company’s foreign (non-Bermuda) subsidiaries which cannot be repatriated in a tax-free manner were repatriated. Due to the Company’s changing corporate structure, the various methods that are available to repatriate earnings, and uncertainty relative to the applicable taxes at the time of repatriation, it is not practicable to determine the amount of tax that would be imposed upon repatriation. If undistributed earnings are repatriated in the future, or are no longer deemed to be indefinitely reinvested, the company will accrue the applicable amount of taxes associated with such earnings at that time. 25. Income taxes (Continued) As of December 31, 2018, $363,560 of the Company’s $368,396 in cash and cash equivalents was held by the Company’s foreign (non-Bermuda) subsidiaries. $131,617 of this cash is held by foreign subsidiaries for which the Company expects to incur and has accrued a deferred tax liability on the repatriation of $25,043 of retained earnings. $231,943 of the Company’s cash and cash equivalents is held by foreign subsidiaries in jurisdictions where no tax is expected to be imposed upon repatriation of the retained earnings of such foreign subsidiaries or is being indefinitely reinvested. On December 22, 2017, the U.S. government enacted comprehensive tax legislation commonly referred to as the Tax Cut and Jobs Act (the “Tax Act”). The Tax Act makes broad and complex changes to the U.S. tax code that affect 2017. The Tax Act also establishes new tax laws that will affect 2018 and subsequent years, including a reduction in the U.S. federal corporate income tax rate from 35% to 21%. On December 22, 2017, the SEC staff issued Staff Accounting Bulletin No. 118 (“SAB 118”), which provides guidance on accounting for the tax effects of the Tax Act. SAB 118 provides a measurement period that should not extend beyond one year from the Tax Act enactment date for companies to complete the accounting under ASC 740, Income Taxes. In accordance with SAB 118, a company must reflect the income tax effects of those aspects of the Tax Act for which the accounting under ASC 740 is complete. To the extent that a company’s accounting for certain income tax effects of the Tax Act is incomplete but it is able to determine a reasonable estimate, it must record a provisional estimate in the financial statements. As a result of the reduction in the federal corporate income tax rate, the Company has revalued its net deferred tax assets, excluding tax credits to the extent affected by changes in the law as of December 31, 2017. Based on this revaluation, the Company has recorded a net income tax expense of $3,182 to reduce its net deferred tax asset balance, which was recorded as additional income tax expense for the year ended December 31, 2017. The Company completed its accounting for the transition tax liability under the Tax Act during the third quarter of 2018 without any impact on income tax expense. There is no material change in the estimates as of September 30, 2018 based on the final calculation of the earnings and profit pool of the Company’s controlled foreign corporations based on the Company’s U.S. tax returns. The Company reports its gain/loss on derivatives designated as cash flow hedges, actuarial gain/loss on retirement benefits and currency translation adjustment, net of taxes to the extent applicable, in accumulated other comprehensive income (loss) (“AOCI”). As of December 31, 2017, due to a reduction in the U.S. federal corporate income tax rate under the Tax Act from 35% to 21%, the Company revalued its net deferred tax assets, including deferred tax liabilities recorded through AOCI. Based on this revaluation, the Company recorded an income tax benefit of $2,265 relating to derivatives, reducing its net deferred tax liability balance, which was recorded as an income tax benefit in continuing operations for the year ended December 31, 2017. In the quarter ended March 31, 2018, the Company elected to early adopt ASU 2018-02, effective January 1, 2018, and made an election to reclassify the stranded income tax effects of the Tax Act from AOCI to retained earnings for all items of AOCI. The Company has elected to adopt the new guidance at the beginning of the period, and no prior periods have been adjusted. Accordingly, a stranded tax effect in AOCI of $2,265 resulting from the Tax Act has been adjusted through retained earnings. 25. Income taxes (Continued) The following table summarizes activities related to our unrecognized tax benefits from January 1 to December 31 for each of 2016, 2017 and 2018: 2016 2017 2018 Opening balance at January 1 $ 26,357 $ 23,467 $ 26,060 Increase related to prior year tax positions, including recorded in acquisition accounting 370 2,582 1,851 Decrease related to prior year tax positions (1,506 ) (1,398 ) (153 ) Decrease related to divesture of business (345 ) — — Decrease related to prior year tax position due to lapse of applicable statute of limitation (2,122 ) (1,019 ) (1,841 ) Increase related to current year tax positions, including recorded in acquisition accounting 3,225 1,661 2,408 Decrease related to settlements with tax authorities (2,000 ) — — Effect of exchange rate changes (512 ) 767 (1,603 ) Closing balance at December 31 $ 23,467 $ 26,060 $ 26,722 As of December 31, 2016, 2017 and 2018, the Company had unrecognized tax benefits amounting to $22,469, $24,877 and $25,485, respectively, which, if recognized, would impact the effective tax rate. As of December 31, 2016, 2017 and 2018, the Company had accrued $3,856, $4,614 and $5,081, respectively, in interest relating to unrecognized tax benefits. During the years ended December 31, 2016, 2017 and 2018, the Company recognized $367, $758 and $467, respectively, including exchange rate differences, in interest on unrecognized tax benefits. As of December 31, 2016, 2017 and 2018, the company had accrued $977, $1,033 and $995, respectively, for penalties. In the next twelve months and for all tax years that remain open to examinations by U.S. federal and various state, local, and non-U.S. tax authorities, the Company estimates that it is reasonably possible that the total amount of its unrecognized tax benefits will vary. However, the Company does not expect significant changes within the next twelve months other than depending on the progress of tax matters or examinations with various tax authorities, which are difficult to predict. With exceptions, the Company is no longer subject to U.S. federal, state and local or non-U.S. income tax audits by taxing authorities for years prior to 2015. The Company’s subsidiaries in India and China are open to examination by relevant taxing authorities for tax years beginning on or after April 1, 2011 and January 1, 2008, respectively. The Company regularly reviews the likelihood of additional tax assessments and adjusts its reserves as additional information or events require.

Segment Reporting [Abstract]
Segment reporting	26. Segment reporting The Company manages various types of business process and information technology services in an integrated manner for clients in various industries and geographic locations. The Company’s Chief Executive Officer, who has been identified as the Chief Operation Decision Maker (CODM), reviews financial information prepared on a consolidated basis, accompanied by disaggregated information about revenue and adjusted operating income by identified business units. The identified business units are organized for operational reasons and represent either services-based, customer-based, industry-based or geography-based units. There is significant overlap between the manner in which the business units are organized. Additionally, the composition and organization of the business units is fluid and the structure changes regularly in response to growth of the overall business, acquisitions and changes in the reporting structure, clients, services, industries served, and delivery centers. Based on an overall evaluation of all facts and circumstances, and after combining operating segments with similar economic characteristics that comply with other aggregation criteria specified in the FASB guidance on segment reporting, the Company has determined that it operates as a single reportable segment. 26.

Accounting Policies [Abstract]
Basis of preparation and principles of consolidation	(a) Basis of preparation and principles of consolidation The accompanying consolidated financial statements have been prepared in accordance with U.S. generally accepted accounting principles (U.S. GAAP). The accompanying consolidated financial statements reflect all adjustments that management considers necessary for a fair presentation of the results of operations for these periods. The accompanying financial statements have been prepared on a consolidated basis and reflect the financial statements of Genpact Limited, a Bermuda company, and all of its subsidiaries that are more than 50% owned and controlled. When the Company does not have a controlling interest in an entity but exerts significant influence over the entity, the Company applies the equity method of accounting. All intercompany transactions and balances are eliminated in consolidation. Non-controlling interest in subsidiaries that is redeemable outside of the Company’s control for cash or other assets is reflected in the mezzanine section between liabilities and equity in the consolidated balance sheets at the redeemable value, which approximates fair value. Redeemable non-controlling interest is adjusted to its fair value at each balance sheet date. Any resulting increases or decreases in the estimated redemption amount are affected by corresponding charges to additional paid-in capital. The share of non-controlling interest in subsidiary earnings is reflected in net loss (income) attributable to redeemable non-controlling interest in the consolidated statements of income.
Use of estimates	(b) Use of estimates The preparation of consolidated financial statements in accordance with U.S. GAAP requires management to make estimates and assumptions that affect the amounts reported in the consolidated financial statements. Significant items subject to such estimates and assumptions include the useful lives of property, plant and equipment, intangibles and goodwill, revenue recognition, reserves for doubtful receivables, valuation allowances for deferred tax assets, the valuation of derivative financial instruments, measurements of stock-based compensation, assets and obligations related to employee benefits, and income tax uncertainties and other contingencies. Management believes that the estimates used in the preparation of the consolidated financial statements are reasonable. Although these estimates are based upon management’s best knowledge of current events and actions, actual results could differ from these estimates. Any changes in estimates are adjusted prospectively in the Company’s consolidated financial statements.
Changes in Accounting Policies	(c) Changes in accounting policies Except as described below, the Company has applied accounting policies consistently to all periods presented in these consolidated financial statements. The Company adopted Accounting standard codification (ASC) Topic 606, Revenue from Contracts with Customers (“Topic 606”), effective January 1, 2018. The revenue accounting policy followed by the company before its adoption of Topic 606 is described below. 2. Summary of significant accounting policies (Continued) The Company derives its revenue primarily from business process outsourcing and information technology services, which are provided on a time-and-material, transaction or fixed-price basis. The Company recognizes revenue when persuasive evidence of an arrangement exists, the sales price is fixed or determinable, services have been rendered and collectability is reasonably assured. Revenues from services rendered under time-and-materials and transaction-based contracts are recognized as the services are provided. The Company’s fixed-price contracts include contracts for application development, maintenance and support services. Revenues from these contracts are recognized ratably over the term of the agreement. The Company accrues for revenue and unbilled receivables for the services rendered between the last billing date and the balance sheet date. Customer contracts can also include incentive payments received for discrete benefits delivered to clients. Revenues relating to such incentive payments are recorded when the contingency is satisfied and the Company concludes the amounts are earned. Revenue from fixed-price contracts for the development of software and related services is recognized in accordance with the percentage-of-completion method. Guidance has been drawn from Financial Accounting Standards Board (“FASB”) guidance on Software—Revenue Recognition to account for revenue from fixed-price arrangements for software development and related services in conformity with FASB guidance on Revenue Recognition—Construction—Type and Production-Type Contracts. The input (effort or cost expended) method has been used to measure progress towards completion as there is a direct relationship between input and productivity. Provisions for estimated losses, if any, on uncompleted contracts are recorded in the period in which such losses become probable based on the current contract estimates. The Company has deferred the revenue and costs attributable to certain process transition activities with respect to its customers where such activities do not represent the culmination of a separate earnings process. Such revenue and costs are subsequently recognized ratably over the period in which the related services are performed. Further, the deferred costs are limited to the amount of the deferred revenues. Revenues are reported net of value-added tax, business tax and applicable discounts and allowances. Reimbursements of out-of-pocket expenses received from clients have been included as part of revenues. The Company enters into multiple-element revenue arrangements in which a client may purchase a combination of its services. Revenue from multiple-element arrangements is recognized, for each element, based on (1) the attainment of the delivery criterion; (2) its fair value, which is determined using the selling price hierarchy of vendor-specific objective evidence (“VSOE”) of fair value, third-party evidence or best estimated selling price, as applicable, and (3) its allocated selling price, which is based on the relative sales price method. The Company has changed its accounting policy for revenue recognition as detailed below. The Company applied Topic 606 using the modified retrospective method, which involves recognizing the cumulative effect of initially applying Topic 606 as an adjustment to the Company’s opening equity balance as of January 1, 2018. Therefore, comparative information has not been adjusted and continues to be reported under Topic 605. As a result of the Company’s adoption of this new standard, certain sales incentive programs meet the requirements for capitalization. Such costs are amortized over the period of expected benefit rather than being expensed as incurred as was the Company’s prior practice. The cumulative impact of the adoption of this standard 2. Summary of significant accounting policies (Continued) resulted in an increase in retained earnings of $17,924 as of January 1, 2018 with a corresponding impact on contract cost assets of $23,227 and deferred tax liabilities of $5,303 . As of January 1, 2018, contract assets and contract liabilities of $21,348 relating to the same customer contracts have been offset against each other.
Revenue recognition	(d) Revenue recognition (effective January 1, 2018) The Company derives its revenue primarily from business process outsourcing and information technology services, which are provided primarily on a time-and-material, transaction or fixed-price basis. The Company recognizes revenue when the promised services are delivered to customers for an amount that reflects the consideration to which the Company expects to be entitled in exchange for those services. Revenues from services rendered under time-and-material and transaction-based contracts are recognized as the services are provided. The Company’s fixed-price contracts include contracts for application development, maintenance and support services. Revenues from these contracts are recognized ratably over the term of the agreement. The Company accrues for revenue and unbilled receivables for services rendered between the last billing date and the balance sheet date. The Company’s customer contracts sometimes also include incentive payments received for discrete benefits delivered or promised to be delivered to clients or service level agreements that could result in credits or refunds to the client. Revenues relating to such arrangements are accounted for as variable consideration when the amount of revenue to be recognized can be estimated to the extent that it is probable that a significant reversal of any incremental revenue will not occur The Company records deferred revenue attributable to certain process transition activities where such activities do not represent separate performance obligations. Revenues relating to such transition activities are classified under contract liabilities and subsequently recognized ratably over the period in which the related services are performed. Costs relating to such transition activities are fulfillment costs which are directly related to the contract and result in the generation or enhancement of resources. Such costs are expected to be recoverable under the contract and are therefore classified as contract cost assets and recognized ratably over the estimated expected period of benefit under cost of revenue. Revenues are reported net of value-added tax, business tax and applicable discounts and allowances. Reimbursements of out-of-pocket expenses received from clients have been included as part of revenues. Revenue for performance obligations that are satisfied over time is recognized in accordance with the methods prescribed for measuring progress. The input (effort or cost expended) method has been used to measure progress towards completion as there is a direct relationship between input and productivity. Provisions for estimated losses, if any, on uncompleted contracts are recorded in the period in which such losses become probable based on the current contract estimates. The Company enters into multiple-element revenue arrangements in which a client may purchase a combination of products or services. Revenue from multiple-element arrangements is recognized, for each element, based on an allocation of the transaction price to each performance obligation on a relative standalone basis. Certain contracts may include offerings such as sale of licenses, which may be perpetual or subscription-based. Revenue from distinct perpetual licenses is recognized upfront at the point in time when the software is made available to the customer. Revenue from distinct subscription-based licenses is recognized at the point in time it is transferred to the client. Revenue from any associated maintenance or ongoing support services is recognized ratably over the term of the contract. For a combined software license/services performance obligation, revenue is recognized over the period that the services are performed. 2. Summary of significant accounting policies (Continued) All incremental and direct costs incurred for acquiring contracts, such as certain sales commissions, are classified as contract cost assets. Such costs are amortized over the expected period of benefit and recorded under selling, general and administrative expenses. Other upfront fees paid to clients are classified as contract assets. Such costs are amortized over the expected period of benefit and recorded as an adjustment to the transaction price and subtracted from revenue. Timing of revenue recognition may differ from the timing of invoicing. If a payment is received in respect of services prior to the delivery of services, the payment is recognized as an advance from clients and classified as a contract liability. Contract assets and contract liabilities relating to the same client contract are offset against each other and presented on a net basis in the consolidated financial statements. See note 27 for information and related disclosures regarding contract balances. Significant judgements The Company often enters into contracts with clients that include promises to transfer multiple products and services to the client. Determining whether products and services are considered distinct performance obligations that should be accounted for separately rather than together may require significant judgment. Judgment is also required to determine the standalone selling price for each distinct performance obligation. In instances where the standalone selling price is not directly observable, it is determined using information that may include market conditions and other observable inputs. Client contracts sometimes include incentive payments received for discrete benefits delivered to clients or service level agreements that could result in credits or refunds to the client. Such amounts are estimated at contract inception and are adjusted at the end of each reporting period as additional information becomes available only to the extent that it is probable that a significant reversal of any incremental revenue will not occur. 2. Summary of significant accounting policies (Continued) Impact on consolidated financial statements The following tables summarize the impact of the Company’s adoption of Topic 606 on its consolidated financial statements for the year ended December 31, 2018.

Following the adoption of ASC 606, the Company capitalized such costs in an amount of $17,452, resulting in a net adjustment of $2,664 and a tax impact of $(681) which is further adjusted by note (g) below. (g) Following the adoption of ASC 606, the Company offset certain contract assets against contract liabilities related to the same client contract in an amount of $8,077.
Accounts receivable	(e) Accounts receivable Accounts receivable are recorded at the invoiced or to be invoiced amount and do not bear interest. Amounts collected on trade accounts receivable are included in net cash provided by operating activities in the consolidated statements of cash flows. The Company maintains an allowance for doubtful accounts for estimated losses inherent in its accounts receivable portfolio. In establishing the required allowance, management considers historical losses adjusted to take into account current market conditions and clients’ financial conditions, the amount of receivables in dispute, and the current receivables’ aging and current payment patterns. Account balances are charged off against the allowance after all means of collection have been exhausted and the potential for recovery is considered remote. The Company does not have any off-balance-sheet credit exposure related to its clients.
Cash and cash equivalents	(f) Cash and cash equivalents Cash and cash equivalents consist of cash and bank balances and all highly liquid investments purchased with an original maturity of three months or less.
Short- term investments	(g) Short-term investments All liquid investments with an original maturity greater than 90 days but less than one year are considered to be short-term investments. Marketable short-term investments are classified and accounted for as available-for-sale investments. Available-for-sale investments are reported at fair value with changes in unrealized gains and losses recorded as a separate component of other comprehensive income (loss) until realized. Realized gains and losses on investments are determined based on the specific identification method and are included in “Other income (expense), net.” The Company does not hold these investments for speculative purposes.
Property, plant and equipment, net	(h) Property, plant and equipment, net Property, plant and equipment are stated at cost less accumulated depreciation and amortization. Expenditures for replacements and improvements are capitalized, whereas the costs of maintenance and repairs are charged to earnings as incurred. The Company depreciates and amortizes all property, plant and equipment using the straight-line method over the following estimated economic useful lives of the assets: Years Buildings 40 Furniture and fixtures 4 Computer equipment and servers 4 Plant, machinery and equipment 4 Computer software 4-7 Leasehold improvements Lesser of lease period or 10 Years Vehicles 3-4 The Company capitalizes certain computer software and software development costs incurred in connection with developing or obtaining computer software for internal use when both the preliminary project stage is completed and it is probable that the software will be used as intended. Capitalized software costs include only (i) external direct costs of materials and services utilized in developing or obtaining computer software, (ii) compensation and related benefits for employees who are directly associated with the software project, and (iii) interest costs incurred while developing internal-use computer software. 2. Summary of significant accounting policies (Continued) Capitalized computer software costs are included in property, plant and equipment on the Company’s balance sheet and amortized on a straight-line basis when placed into service over the estimated useful lives of the software. Advances paid towards acquisition of property, plant and equipment outstanding as of each balance sheet date and the cost of property, plant and equipment not put to use before such date are disclosed under “Capital work in progress.”
Business combinations	(i) Business combinations, goodwill and other intangible assets The Company accounts for its business combinations using the acquisition method of accounting in accordance with ASC 805, Business Combinations, by recognizing the identifiable tangible and intangible assets acquired and liabilities assumed, and any non-controlling interest in the acquired business, measured at their acquisition date fair values. Contingent consideration is included within the acquisition cost and is recognized at its fair value on the acquisition date. A liability resulting from contingent consideration is remeasured to fair value as of each reporting date until the contingency is resolved. Changes in fair value are recognized in earnings. All assets and liabilities of the acquired businesses, including goodwill, are assigned to reporting units. Acquisition-related costs are expensed as incurred under Selling, General and Administrative Expenses. In business combinations, where the fair value of identifiable tangible and intangible net assets purchased exceeds the cost of the acquired business, the Company recognizes the resulting gain under “Other operating (income) expense, net” in the Consolidated Statements of Income.
Goodwill	Goodwill represents the cost of acquired businesses in excess of the fair value of identifiable tangible and intangible net assets purchased. Goodwill is not amortized but is tested for impairment at least on an annual basis on December 31, based on a number of factors, including operating results, business plans and future cash flows. The Company performs an assessment of qualitative factors to determine whether the existence of events or circumstances leads to a determination that it is more likely than not that the fair value of a reporting unit is less than its carrying amount. Based on the assessment of events or circumstances, the Company performs a quantitative assessment of goodwill impairment if it determines that it is more likely than not that the fair value of a reporting unit is less than its carrying amount. If, based on the quantitative impairment analysis, the carrying value of the goodwill of a reporting unit exceeds the fair value of such goodwill, an impairment loss is recognized in an amount equal to the excess. In addition, the Company performs a qualitative assessment of goodwill impairment between annual tests if an event occurs or circumstances change that would more likely than not reduce the fair value of a reporting unit below its carrying amount. See Note 10 for information and related disclosures.
Other Intangible Assets	Intangible assets including technology acquired / developed individually or with a group of other assets or in a business combination are carried at cost less accumulated amortization based on their estimated useful lives as follows: Customer-related intangible assets 1-14 years Marketing-related intangible assets 1-10 years Technology-related intangible assets 2-8 years Other intangible assets 3-5 years Intangible assets are amortized over their estimated useful lives using a method of amortization that reflects the pattern in which the economic benefits of the intangible assets are consumed or otherwise realized. The Company also capitalizes certain software and technology development costs incurred in connection with developing or obtaining software or technology for sale/lease to customers when the initial design phase is completed and commercial and technological feasibility has been established. Any development cost incurred before technological feasibility is established is expensed as incurred as research and development costs. Technological feasibility is established upon completion of a detailed design program or, in its absence, completion of a working model. Capitalized software and technology costs include only (i) external direct costs of materials and services utilized in developing or obtaining software and technology and (ii) compensation and related benefits for employees who are directly associated with the project. Costs incurred in connection with developing or obtaining software or technology for sale/lease to customers which are under development and not put to use are disclosed under “intangible assets under development.” Advances paid toward the acquisition of intangible assets outstanding as of each balance sheet date are disclosed under “intangible assets under development.” Capitalized software and technology costs are included in intangible assets under technology-related intangible assets on the Company’s balance sheet and amortized on a straight-line basis when placed into service over the estimated useful lives of the software and technology.
Impairment of long-lived assets	(j) Impairment of long-lived assets Long-lived assets, including certain intangible assets, to be held and used are reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount of such assets may not be recoverable. Such assets are required to be tested for impairment if the carrying amount of the assets is higher than the future undiscounted net cash flows expected to be generated from the assets. The impairment amount to be recognized is measured as the amount by which the carrying value of the assets exceeds their fair value. The Company determines fair value by using a discounted cash flow approach.
Foreign currency	(k) Foreign currency The Company’s consolidated financial statements are reported in U.S. dollars, the Company’s functional currency. The functional currency for the Company’s subsidiaries organized in Europe, other than the United Kingdom, the Czech Republic, Luxembourg and one subsidiary in Poland, is the euro, and the functional currencies of the Company’s subsidiaries organized in Brazil, China, Colombia, Guatemala, India, Israel, Japan, Morocco, South Africa, the Philippines, Poland, the Czech Republic, Hong Kong, Singapore, Australia and Canada are their respective local currencies. The functional currency of all other Company subsidiaries is the U.S. dollar. The translation of the functional currencies of the Company’s subsidiaries into U.S. dollars is performed for balance sheet accounts using the exchange rates in effect as of the balance sheet date and for revenues and expense accounts using a monthly average exchange rate prevailing during the respective period. The gains or losses resulting from such translation are reported as currency translation adjustments under other comprehensive income (loss), net, under accumulated other comprehensive income (loss) as a separate component of equity. Monetary assets and liabilities of each subsidiary denominated in currencies other than the subsidiary’s functional currency are translated into their respective functional currency at the rates of exchange prevailing on the balance sheet date. Transactions of each subsidiary in currencies other than the subsidiary’s functional currency are translated into the respective functional currencies at the average monthly exchange rate prevailing during the period of the transaction. The gains or losses resulting from foreign currency transactions are included in the consolidated statements of income.
Derivative instruments and hedging activities	2. Summary of significant accounting policies (Continued) (l) Derivative instruments and hedging activities In the normal course of business, the Company uses derivative financial instruments to manage fluctuations in foreign currency exchange rates and interest rate fluctuation. The Company purchases forward foreign exchange contracts to mitigate the risk of changes in foreign exchange rates on intercompany transactions and forecasted transactions denominated in foreign currencies and interest rate swaps to mitigate interest rate fluctuation risk on its indebtedness. The Company recognizes derivative instruments and hedging activities as either assets or liabilities in its consolidated balance sheets and measures them at fair value. Gains and losses resulting from changes in fair value are accounted for depending on the use of the derivative and whether it is designated and qualifies for hedge accounting. Changes in the fair values of derivatives designated as cash flow hedges are deferred and recorded as a component of other comprehensive income (loss) reported under accumulated other comprehensive income (loss) until the hedged transactions occur and are then recognized in the consolidated statements of income along with the underlying hedged item and disclosed as part of “Total net revenues,” “Cost of revenue,” “Selling, general and administrative expenses,” and “Interest expense,” as applicable. Changes in the fair value of derivatives not designated as hedging instruments and the ineffective portion of derivatives designated as cash flow hedges are recognized in the consolidated statements of income and are included in foreign exchange gains (losses), net, and other income (expense), net, respectively. With respect to derivatives designated as hedges, the Company formally documents all relationships between hedging instruments and hedged items, as well as its risk management objectives and strategy for undertaking various hedge transactions. The Company also formally assesses, both at the inception of the hedge and on a quarterly basis, whether each derivative is highly effective in offsetting changes in fair values or cash flows of the hedged item. If it is determined that a derivative or portion thereof is not highly effective as a hedge, or if a derivative ceases to be a highly effective hedge, the Company will prospectively discontinue hedge accounting with respect to that derivative. In all situations in which hedge accounting is discontinued and the derivative is retained, the Company continues to carry the derivative at its fair value on the balance sheet and recognizes any subsequent change in its fair value in the consolidated statements of income. When it is probable that a forecasted transaction will not occur, the Company discontinues hedge accounting and recognizes immediately, in foreign exchange gains (losses), net in the consolidated statements of income, the gains and losses attributable to such derivative that were accumulated in other comprehensive income (loss).
Income taxes	(m) Income taxes The Company accounts for income taxes using the asset and liability method of accounting for income taxes. Under this method, income tax expense is recognized for the amount of taxes payable or refundable for the current year. In addition, deferred tax assets and liabilities are recognized for future tax consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their tax bases and all operating loss and tax credit carry forwards, if any. Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled. The effect on deferred tax assets and liabilities of a change in tax laws or rates is recognized in the statement of income in the period that includes the enactment date. Deferred tax assets are reduced by a valuation allowance if, based on the weight of available evidence, it is more likely than not that some portion or all of the deferred tax assets will not be realized. 2. Summary of significant accounting policies (Continued) The Company applies a two-step approach for recognizing and measuring the benefit of tax positions. The first step is to evaluate the tax position for recognition by determining, based on the technical merits, that the position will more likely than not be sustained upon examination. The second step is to measure the tax benefit as the largest amount of the tax benefit that is greater than 50 percent likely of being realized upon settlement. The Company includes interest and penalties related to underpayment of income taxes within income tax expense. The Company follows the specific identification approach for releasing stranded tax effects from AOCI upon recognition of these AOCI items in the Company’s statement of income.
Employee benefit plans	(n) Employee benefit plans Contributions to defined contribution plans are charged to consolidated statements of income in the period in which services are rendered by the covered employees. Current service costs for defined benefit plans are accrued in the period to which they relate. The liability in respect of defined benefit plans is calculated annually by the Company using the projected unit credit method. Prior service cost, if any, resulting from an amendment to a plan is recognized and amortized over the remaining period of service of the covered employees. The Company recognizes its liabilities for compensated absences dependent on whether the obligation is attributable to employee services already rendered, relates to rights that vest or accumulate and payment is probable and estimable. On January 1, 2018, the Company adopted ASU 2017-07, Compensation-Retirement Benefits (Topic 715): Improving the Presentation of Net Periodic Pension Cost and Net Periodic Postretirement Benefit Cost. The service cost is recognized under “cost of revenue” and “selling, general and administrative expenses,” depending on the functional area of the underlying employees included in the plans, and the non-operating components of net benefit plan costs are included within “other income (expense), net” in the consolidated statements of income. The Company records annual amounts relating to its defined benefit plans based on calculations that incorporate various actuarial and other assumptions, including discount rates, mortality, assumed rates of return, compensation increases and turnover rates. The Company reviews its assumptions on an annual or quarterly basis and makes modifications to the assumptions based on current rates and trends when it is appropriate to do so. The effect of modifications to those assumptions is recorded in other comprehensive income (loss) and amortized to net periodic cost over future periods using the corridor method. The Company believes that the assumptions utilized in recording its obligations under its plans are reasonable based on its experience and market conditions.
Deferred Compensation Plans	( o Deferred Compensation Plans The Company maintains a non-qualified deferred compensation plan for certain employees. The plan is accounted for using the fair value measurement approach. Plan earnings are calculated by reference to actual earnings of the funds chosen by individual participants. In connection with the administration of this plan, the Company has purchased Company-owned life insurance policies insuring the lives of certain employees, held under a Rabbi Trust. The Company consolidates the invested assets of the trust. The cash surrender value of these insurance policies is included in “other assets” in the consolidated balance sheets at fair value. Gains or losses on the plan’s assets and changes in the fair value of deferred compensation liabilities are included in “other income (expense), net,” and “selling, general and administrative expenses,” respectively, in the consolidated statements of income.
Stock-based compensation	(p) Stock-based compensation The Company recognizes and measures compensation expense for all stock-based awards based on the grant date fair value. For option awards, grant date fair value is determined under the option-pricing model (Black-Scholes-Merton) and for awards other than option awards, grant date fair value is determined on the basis of the fair market value of a Company common share on the date of grant of such awards. The Company recognizes compensation expense for stock-based awards net of estimated forfeitures. Stock-based compensation recognized in the consolidated statements of income is based on awards ultimately expected to vest. As a result, the expense has been reduced for estimated forfeitures. Forfeitures are estimated at the time of grant and revised, if necessary, in subsequent periods if actual forfeitures differ from such estimates.
Accelerated Share Repurchase	2. Summary of significant accounting policies (Continued) (q) Accelerated Share Repurchase The Company entered into an accelerated share repurchase (“ASR”) agreement in 2017 with a third-party financial institution to repurchase shares of the Company’s common stock. Under the ASR agreement, the Company paid an upfront amount to the financial institution and received an initial delivery of shares. Upon an interim delivery and settlement of the ASR agreement, the financial institution delivered
Government incentives	(r) Government incentives The Company recognizes incentives in the consolidated statement of income under “other income (expense), net.” Incentives are recognized in the income statement when there is reasonable assurance that the Company will comply with the conditions for their receipt and a reasonable expectation that the funds will be received. In certain circumstances, the receipt of an incentive may not be subject to any condition or requirement to incur further costs, in which case the incentive is recognized in the income statement for the period in which it becomes receivable. In the event that it becomes likely that the Company will be required to repay an incentive that has already been recognized, the Company makes a provision for the estimated liability.
Financial instruments and concentration of credit risk	(s) Financial instruments and concentration of credit risk Financial instruments that potentially subject the Company to concentration of credit risk are reflected principally in cash and cash equivalents, derivative financial instruments and accounts receivable. The Company places its cash and cash equivalents and derivative financial instruments with corporations and banks with high investment grade ratings, limits the amount of credit exposure with any one corporation or bank and conducts ongoing evaluations of the creditworthiness of the corporations and banks with which it does business. To reduce its credit risk on accounts receivable, the Company conducts ongoing credit evaluations of its clients. GE accounted for 11% of the Company’s receivables as of both December 31, 2017 and 2018. GE accounted for 14%, 10% and 9% of the Company’s revenues in the years ended December 31, 2016, 2017 and 2018, respectively.
Earnings (loss) per share	(t) Earnings (loss) per share Basic earnings per share is computed using the weighted average number of common shares outstanding during the period. Diluted earnings per share is computed using the weighted average number of common and dilutive common equivalent shares outstanding during the period. For the purposes of calculating diluted earnings per share, the treasury stock method is used for stock-based awards except where the results would be anti-dilutive.
Commitments and contingencies	(u) Commitments and contingencies Liabilities for loss contingencies arising from claims, assessments, litigation, fines and penalties, and other sources are recorded when it is probable that a liability has been incurred and the amount of the assessment and/or remediation can be reasonably estimated. Legal costs incurred in connection with such liabilities are expensed as incurred.
Debt Restructuring	(v) Debt Restructuring The Company accounts for any restructuring of its credit facility using the ten percent cash flow test in accordance with ASC 470, Debt. If the cash flow effect of the change in terms on a present-value basis is less than ten percent, the debt instruments are not considered to be substantially different, and are accounted for as a modification. If the change is more than ten percent, it is treated as an extinguishment. In performing the cash flow test, the Company includes all amounts paid to its lenders in connection with the restructuring but excludes third party expenses. In the case of a modification, all new fees paid to lenders are capitalized and amortized as part of the existing effective yield and any new fees paid to third parties are expensed as incurred under selling, general and administrative expenses. No gain or loss is recorded in the case of a modification. In the case of an extinguishment, all new fees paid to lenders are expensed as incurred under selling, general and administrative expenses and any new fees paid to third parties are capitalized and amortized as a debt issuance cost. The old debt is derecognized and the new debt is recorded at fair value and a gain or loss is recorded for the difference between the net carrying value of the original debt and the fair value of the new debt .
Recently issued accounting pronouncements	(w) Recently issued accounting pronouncements The authoritative bodies release standards and guidance which are assessed by management for impact on the company’s consolidated financial statements. The following recently released accounting standard has been adopted by the Company: In March 2016, the FASB issued ASU 2016-09, Compensation—Stock Compensation (Topic 718): Improvement to Employee Share-Based Payment Accounting. The new standard contains several amendments that will simplify the accounting for employee share-based payment transactions, including the accounting for income taxes, forfeitures, statutory tax withholding requirements, classification of awards as either equity or liabilities, and classification on the statement of cash flows. The changes in the new standard eliminate the requirement for excess tax benefits to be recognized in additional paid-in capital and tax deficiencies recognized either in income tax expense or in additional paid-in capital. In the quarter ended December 31, 2016, the Company elected to early adopt ASU 2016-09 effective January 1, 2016 and applied ASU 2016-09 using a modified retrospective approach. The treatment of forfeitures has not changed as the Company is electing to continue its current process of estimating the number of forfeitures. With the early adoption of ASU 2016-09, the Company has elected to present the cash flow statement on a prospective transition method and no prior periods have been adjusted. The Company adopted ASC Topic 606, Revenue from Contracts with Customers, In February 2018, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 2018-02, “Income Statement – Reporting Comprehensive Income (Topic 220): Reclassification of Certain Tax Effects from Accumulated Other Comprehensive Income.” The new standard provides guidance to “allow a reclassification from accumulated other comprehensive income (“AOCI”) to retained earnings for stranded tax effects resulting from the Tax Cuts and Jobs Act.” The guidance is effective for fiscal years beginning after December 15, 2018, including interim periods within those years, and the guidance may be applied either in the period of adoption or retrospectively to each period (or periods) in which the effect of the change in the U.S. federal income tax rate in the Tax Cuts and Jobs Act is recognized. Early adoption is permitted. On January 1, 2018, the Company elected the early adoption of ASU 2018-02, which was adopted at the beginning of the period and no prior periods have been adjusted. In addition, the following recently released accounting standards have been adopted by the Company. Adoption of these standards did not have a material impact on the Company’s consolidated results of operations, cash flows, financial position or disclosures: Effective January 1, 2016, the Company adopted FASB ASU 2015-01 (Topic 225): Simplifying Income Statement Presentation by Eliminating the Concept of Extraordinary Items (“ASU 2015-01”). Such items are defined as transactions or events that are both unusual in nature and infrequent in occurrence, and, currently, are required to be presented separately in the income statement, net of income tax, after income from continuing operations. The changes eliminate the concept of an extraordinary item and, therefore, the presentation of such items will no longer be required. Notwithstanding this change, the Company will still be required to present and disclose a transaction or event that is both unusual in nature and infrequent in occurrence in the notes to the consolidated financial statements. Effective January 1, 2016, the Company adopted FASB ASU 2015-16 (Topic 805), Business Combinations (“ASU 2015-16”), which eliminates the requirement for an acquirer in a business combination to account for measurement-period adjustments retrospectively. The guidance requires that the acquirer shall recognize adjustments to provisional amounts that are identified during the measurement period in the reporting period in which the adjustment amounts are determined. 2. Summary of significant accounting policies (Continued) Effective January 1, 2016, the Company adopted FASB ASU 2015-02. In February 2015, the FASB issued ASU No. 2015-02, Amendment to the Consolidation Analysis, which specifies changes to the analysis that an entity must perform to determine whether it should consolidate certain types of legal entities. These changes (i) modify the evaluation of whether limited partnerships and similar legal entities are variable interest entities or voting interest entities, (ii) eliminate the presumption that a general partner should consolidate a limited partnership, (iii) affect the consolidation analysis of reporting entities that are involved with variable interest entities, particularly those that have fee arrangements and related party relationships, and (iv) provide a scope exception from consolidation guidance for reporting entities with interests in legal entities that are required to comply with or operate in accordance with requirements that are similar to those in Rule 2a-7 of the Investment Company Act of 1940 for registered money market funds. Effective January 1, 2017, the Company adopted FASB ASU 2016-06, Derivatives and Hedging (Topic 815). The amendments in this update clarify the requirements for assessing whether contingent call (put) options that can accelerate the payment of principal on debt instruments are clearly and closely related to their debt hosts. An entity performing the assessment under the amendments in this update is required to assess the embedded call (put) options solely in accordance with a four-step decision sequence. Effective January 1, 2017, the Company early adopted FASB ASU 2016-15, "Statement of Cash Flows: Classification of Certain Cash Receipts and Cash Payments." The new guidance is intended to reduce diversity in how certain transactions are classified in the statement of cash flows. Effective January 1, 2018, the Company adopted FASB ASU 2017-01, “Business Combinations (Topic 805): Clarifying the Definition of a Business.” The new guidance revises the definition of a business. The definition of a business affects many areas of accounting (e.g., acquisitions, disposals, goodwill impairment, consolidation). Effective January 1, 2018, the Company adopted FASB ASU 2016-16, “Intra-Entity Transfers of Assets Other Than Inventory.” The new guidance eliminates the exception for deferment of tax recognition until the transferred asset is sold to a third party or otherwise recovered through use for all intra-entity sales of assets other than inventory. Effective January 1, 2018, the Company adopted FASB ASU 2017-07, “Improving the Presentation of Net Periodic Pension Cost and Net Periodic Postretirement Benefit Cost.” The ASU requires entities to (1) disaggregate the current service-cost component from the other components of net benefit cost (the “other components”) and present it with other current compensation costs for related employees in the income statement and (2) present the other components elsewhere in the income statement and outside of income from operations if that subtotal is presented. In addition, the ASU requires entities to disclose the income statement lines that contain the other components if they are not presented on appropriately described separate lines. The following recently released accounting standards have not yet been adopted by the Company: In February 2016, FASB established Topic 842, “Leases”, by issuing ASU No. 2016-02, which requires lessees to recognize leases on-balance sheet and disclose key information about leasing arrangements. The ASU requires extensive qualitative and quantitative disclosures, including with respect to significant judgments made by management. Subsequently, the FASB issued ASU No. 2017-13, in September 2017, ASU No. 2018-01, in January 2018, ASU No. 2018-10, in July 2018, ASU No. 2018-11, in July 2018, ASU No. 2018-20, in December 2018 which amends and clarifies ASU 2016-02. The ASU will be effective for the Company beginning January 1, 2019, including interim periods in the fiscal year 2019. Early adoption is permitted. The Company will use a modified retrospective adoption approach using a cumulative effect adjustment to the opening balance of retained earnings in the period of adoption with the effective date as its date of initial application on January 1, 2019 , in its first reporting on adoption The Company has concluded its assessment of adopting ASU No. 2016-02 and expects that this standard will have a material effect on its financial statements. The assessment included reviewing existing leases and service contracts, which may include embedded leases. The Company is in the process of making necessary changes to its policies, processes, and internal controls as well as system enhancements to generate the information necessary for the new disclosures. The most significant effects of this new standard on the Company relate to (1) the recognition of new ROU (“Right of Use”) assets and lease liabilities on its balance sheet for various real estate operating leases and (2) providing significant new disclosures about its leasing activities. 2. Summary of significant accounting policies (Continued) The Company has elected the “package of practical expedients,” which allows the Company not to reassess under the new standard its prior conclusions about lease identification, lease classification and initial direct costs. The Company has also elected As a result of In June 2016, the FASB issued ASU No. 2016-13, “Measurement of credit losses on financial instruments.” The ASU requires measurement and recognition of expected credit losses for financial assets held by the Company. The ASU is effective for the Company beginning January 1, 2020, including interim periods in fiscal year 2020. Subsequently, the FASB issued ASU No. 2018-19, in November 2018 which amends and clarifies some parts of ASU 2016-13.Early adoption is permitted. The Company is in the process of assessing the impact of this ASU on its consolidated results of operations, cash flows, financial position and disclosures. In August 2017, the FASB issued ASU 2017-12, “Derivatives and Hedging.” The amendment expands an entity’s ability to do hedge accounting to non-financial and financial risk components and requires changes in fair value of hedging instruments to be presented in the same income statement line as the hedged item. The ASU also amends the presentation and disclosure requirements for the effect of hedge accounting. Subsequently, the FASB issued ASU No. 2018-16 in October 2018 which includes the Secured Overnight Financing Rate (SOFR) Overnight Index Swap (OIS) rate as a benchmark interest rate for hedge accounting purposes. These ASUs are effective for the Company beginning January 1, 2019, including interim periods in the fiscal year 2019. The Company does not expect the adoption of this update to have a material impact on its consolidated results of operations, cash flows, financial position or disclosures. In August 2018, the FASB issued ASU No. 2018-13, “Disclosure Framework—Changes to the Disclosure Requirements for Fair Value Measurement.” The ASU modifies the disclosure requirements with respect to fair value measurements. The ASU is effective for the Company beginning January 1, 2020, including interim periods in fiscal year 2020. Early adoption is permitted. The Company is in the process of assessing the impact of this ASU on its consolidated results of operations, cash flows, financial position and disclosures. In August 2018, the FASB issued ASU No. 2018-14, “Disclosure Framework—Changes to the Disclosure Requirements for Defined Benefit Plans.” The ASU modifies the disclosure requirements with respect to defined benefit pension plans. The ASU is effective for the Company beginning January 1, 2021. Early adoption is permitted. The Company is in the process of assessing the impact of this ASU on its consolidated results of operations, cash flows, financial position and disclosures. In August 2018, the FASB issued ASU No. 2018-15, “Customer’s Accounting for Implementation Costs Incurred in a Cloud Computing Arrangement That is a Service Contract.” The ASU modifies the capitalization requirements with respect to implementation costs incurred by the customer in a hosting arrangement that is a service contract. The ASU is effective for the Company beginning January 1, 2020. Early adoption is permitted. The Company is in the process of assessing the impact of this ASU on its consolidated results of operations, cash flows, financial position and disclosures.
Reclassification	(w) Reclassification Certain reclassifications have been made in the consolidated financial statements of prior periods to conform to the classification used in the current period. The impact of such reclassifications on the consolidated financial statements is not material.

The fair value measurements of these financial assets and liabilities were determined using the following inputs as of December 31, 2017 and 2018: As of December 31, 2017 Fair Value Measurements at Reporting Date Using Quoted Prices in Active Markets for Identical Assets Significant Other Observable Inputs Significant Other Unobservable Inputs Total (Level 1) (Level 2) (Level 3) Assets Derivative instruments (Note a, c) $ 73,098 $ — $ 73,098 $ — Total $ 73,098 $ — $ 73,098 $ — Liabilities Earn out consideration (Note b, d) $ 24,732 $ — $ — $ 24,732 Derivative instruments (Note b, c) $ 18,188 $ — $ 18,188 $ — Total $ 42,920 $ — $ 18,188 $ 24,732 Redeemable non-controlling interest (Note e) $ 4,750 $ — $ — $ 4,750 As of December 31 2018 Fair Value Measurements at Reporting Date Using Quoted Prices in Active Markets for Identical Assets Significant Other Observable Inputs Significant Other Unobservable Inputs Total (Level 1) (Level 2) (Level 3) Assets Derivative instruments (Note a, c) $ 44,099 $ — $ 44,099 $ — Deferred compensation plan assets (a, f) 1,613 — — 1,613 Total $ 45,712 $ — $ 44,099 $ 1,613 Liabilities Earn-out consideration (Note b, d) $ 17,073 $ — $ — $ 17,073 Derivative instruments (Note b, c) 35,245 — 35,245 — Deferred compensation plan liability (b, g) 1,582 — — 1,582 Total $ 53,900 $ — $ 35,245 $ 18,655 (a) Included in “prepaid expenses and other current assets” and “other assets” in the consolidated balance sheets. (b) Included in “accrued expenses and other current liabilities” and “other liabilities” in the consolidated balance sheets. (c) The Company values its derivative instruments based on market observable inputs, including both forward and spot prices for the relevant currencies and interest rate indices for relevant interest rates. The quotes are taken from an independent market database. (d) The fair value of earn-out consideration, calculated as the present value of expected future payments to be made to the sellers of acquired businesses, was derived by estimating the future financial performance of the acquired businesses using the earn-out formula and performance targets specified in each purchase agreement and adjusting the result to reflect the Company’s estimate of the likelihood of achievement of such targets. Given the significance of the unobservable inputs, the valuations are classified in level 3 of the fair value hierarchy. (e) The Company’s estimate of the fair value of redeemable non-controlling interest as of December 31, 2017 is based on unobservable inputs considering the assumptions that market participants would make in pricing the obligation. Given the significance of the unobservable inputs, the valuation was classified in level 3 of the fair value hierarchy. Refer to Note 3—Business Acquisitions. (f) Deferred compensation plan assets consist of life insurance policies held under a Rabbi Trust. Assets held in the Rabbi Trust are valued based on the cash surrender value of the insurance contract, which is determined based on the fair value of the underlying assets included in the insurance portfolio and are therefore classified within level 3 of the valuation hierarchy. 6. Fair Value Measurements (Continued) (g) The fair value of the deferred compensation plan liability is derived based on the fair value of the underlying assets in the insurance policies and is therefore classified within level 3 of the valuation hierarchy .

[1]	Included in “prepaid expenses and other current assets” and “other assets” in the consolidated balance sheets.
[2]	The Company values its derivative instruments based on market observable inputs, including both forward and spot prices for the relevant currencies and interest rate indices for relevant interest rates. The quotes are taken from an independent market database.
[3]	Deferred compensation plan assets consist of life insurance policies held under a Rabbi Trust. Assets held in the Rabbi Trust are valued based on the cash surrender value of the insurance contract, which is determined based on the fair value of the underlying assets included in the insurance portfolio and are therefore classified within level 3 of the valuation hierarchy.
[4]	Included in “accrued expenses and other current liabilities” and “other liabilities” in the consolidated balance sheets.
[5]	The fair value of earn-out consideration, calculated as the present value of expected future payments to be made to the sellers of acquired businesses, was derived by estimating the future financial performance of the acquired businesses using the earn-out formula and performance targets specified in each purchase agreement and adjusting the result to reflect the Company’s estimate of the likelihood of achievement of such targets. Given the significance of the unobservable inputs, the valuations are classified in level 3 of the fair value hierarchy.
[6]	The fair value of the deferred compensation plan liability is derived based on the fair value of the underlying assets in the insurance policies and is therefore classified within level 3 of the valuation hierarchy.
[7]	The Company’s estimate of the fair value of redeemable non-controlling interest as of December 31, 2017 is based on unobservable inputs considering the assumptions that market participants would make in pricing the obligation. Given the significance of the unobservable inputs, the valuation was classified in level 3 of the fair value hierarchy. Refer to Note 3—Business Acquisitions.
