Accounting Policies [Abstract]
Summary of significant accounting policies	2. Summary of significant accounting policies (a) Basis of preparation and principles of consolidation The unaudited interim consolidated financial statements have been prepared in accordance with U.S. generally accepted accounting principles (U.S. GAAP) for interim financial information and the rules and regulations of the Securities and Exchange Commission for reporting on Form 10-Q. Accordingly, they do not include certain information and note disclosures required by generally accepted accounting principles for annual financial reporting and should be read in conjunction with the consolidated financial statements included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2017. The unaudited interim consolidated financial statements reflect all adjustments that management considers necessary for a fair presentation of the results of operations for these periods. The results of operations for interim periods are not necessarily indicative of results for the full year. The accompanying unaudited interim consolidated 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 on 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 changes 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, determining the nature and timing of satisfaction of performance obligations, determining the standalone selling price of performance obligations, variable consideration, and other obligations for revenue recognition 2. Summary of significant accounting policies (Continued) 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) 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 acquired individually or with a group of other assets or in a business combination and developed internally 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 Other intangible assets 2-9 years 2. Summary of significant accounting policies (Continued) Intangible assets acquired individually or with a group of other assets or in a business combination and developed internally 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 Other intangible assets 2-9 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. (d) 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% and 10% of receivables as of December 31, 2017 and March 31, 2018, respectively. GE accounted for 11% and 8% of total revenue for the three months ended March 31, 2017 and 2018, respectively. (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 condition, 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) 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 Topic 606, Revenue from Contracts with Customers, effective January 1, 2018. As a result, 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 expensed as incurred per the Company’s prior practice. The cumulative impact of the adoption of this standard 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 liability of $5,303 2. Summary of significant accounting policies (Continued) Revenue Recognition The Company derives its revenue primarily from business process outsourcing and information technology services, which primarily are provided 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 entity expects to be entitled in exchange for those services. 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 or promised to be delivered to clients or service level agreements that could result in credits or refunds to the customer. 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 has deferred revenue attributable to certain process transition activities, with respect to its customers where such activities do not represent separate performance obligation. 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 generation or enhancement of resources and are expected to be recoverable under the contract and thereby classified as contract cost assets and are 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 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 subscription based licenses is recognized as ratably over the subscription term. All incremental and direct costs incurred for acquiring contracts, such as certain sales commission, are classified as contract cost asset. Such costs are amortized over the expected period of benefit and recorded under Selling, General and Administrative Expenses. Other upfront fees paid to customers are classified as contract asset. Such costs are amortized over the expected period of benefit and recorded as an adjustment to the transaction price and reduced from revenue. Timing of revenue recognition may differ from the timing of invoicing to customers. If payment is received in respect of services prior to the delivery of services, the payment is recognized as an advance from customers and classified as contract liabilities. Contract assets and contract liabilities relating to the same customer contract have been offset and presented on a net basis in the consolidated financial statements. See note 19 for information and related disclosures regarding contract balances. 2. Summary of significant accounting policies (Continued) For a description of the Company’s revenue recognition accounting policy in effect before the Company’s adoption of ASC 606, see Note 3—“Summary of significant accounting policies” under Item 1 —“Financial Statements” and Part II, Item 7—“Management’s Discussion and Analysis of Financial Condition and Results of Operations”—“Critical Accounting Policies and Estimates” in the Company’s Annual Report on Form 10-K for the year ended December 31, 2017. Significant judgements The Company has contracts with customers which often include promises to transfer multiple products and services to the customer. Determining whether products and services are considered distinct performance obligations that should be accounted for separately versus 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. Customer contracts can include incentive payments received for discrete benefits delivered to clients or service level agreements that could result in credits or refunds to the customer. 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.

Summary of significant accounting policies (Continued) (g) Recently issued and adopted accounting pronouncements The authoritative bodies release standards and guidance which are assessed by management for impact on the Company’s consolidated financial statements. The Company has adopted the following recently released accounting standards: The Company adopted 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 Company has adopted the following recently released accounting 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, 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 2. Summary of significant accounting policies (Continued) ASU requires entities to disclose the income statement lines that contain the other components if they are not presented on appropriately described separate lines. 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. The following recently released accounting standards have not yet been adopted by the Company: In February 2016, the FASB issued ASU No. 2016-02, “Leases.” The core principle of the ASU is that a lessee should recognize the assets and liabilities that arise from its leases other than those that meet the definition of a short-term lease. 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, 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 expects to complete its assessment of adopting ASU No. 2016-02 in the third quarter of 2018. The Company continues to evaluate the impact of its pending adoption of ASU 2016-02 on its consolidated results of operations, cash flows, financial position and disclosures, and the Company’s preliminary assessments are subject to change. In August 2017, the FASB issued ASU 2017-12, “Derivatives and Hedging.” The amendment expands an entity’s ability to 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. The ASU must be adopted using a modified retrospective approach with a cumulative effect adjustment recorded to the opening balance of retained earnings as of the initial application date. The ASU is effective for the Company beginning January 1, 2019, including interim periods in the fiscal year 2019. 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. (h) 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.

Business acquisitions	3. Business acquisitions A. Certain acquisitions (a) Strategic Sourcing Excellence Limited On January 8, 2016, the Company acquired 51% of the outstanding equity interest in Strategic Sourcing Excellence LLC (“SSE”), a Delaware limited liability company. The total consideration paid by the Company to the selling equity holders for the acquired interest in SSE was $14,541. This amount includes the fair value of earn-out consideration, cash consideration of $2,550, and an adjustment for working capital, transaction expenses and indebtedness. During the quarter ended December 31, 2016, the Company recorded certain measurement period adjustments. These measurement period adjustments did not have a significant impact on the Company’s consolidated statements of income, balance sheets or cash flows in any period. The equity purchase agreement between the Company and the selling equity holders of SSE also provided for contingent earn-out consideration of up to $20,000, payable by the Company to the selling equity holders based on the future performance of the acquired business relative to the thresholds specified in the earn-out calculation. Up to $9,800 of the total potential earn-out consideration, representing the selling equity holders’ 49% interest in SSE, was payable only if either the put or call option, each as described below, was exercised. This acquisition enhances the Company’s sourcing and procurement consulting domain expertise. The equity purchase agreement granted the Company a call option to purchase the remaining 49% equity interest in SSE, which option the Company had the right to exercise between January 1, 2018 and January 31, 2018. Since the Company did not exercise its call option during such period, the selling equity holders exercised their put option on March 1, 2018 in accordance with the terms of the equity purchase agreement to require the Company to purchase their 49% interest in SSE for $2,950. The Company also paid $1,780 in earn-out consideration to the selling equity shareholders during the three months ended March 31, 2018. The amount paid in excess of carrying amount has been recorded in additional paid-in capital.

(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 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 is classified in level 3 of the fair value hierarchy. See Note 3—Business Acquisitions. The following table provides a roll-forward of the fair value of earn-out consideration categorized as level 3 in the fair value hierarchy for the three months ended March 31, 2017 and 2018: Three months ended March 31, 2017 2018 Opening balance $ 22,435 $ 24,732 Earn-out consideration payable in connection with Acquisitions 2,320 — Payments made on earn-out consideration (1,206 ) (1,476 ) Change in fair value of earn-out consideration (Note a) (3,138 ) 17 Others (Note b) 852 627 Ending balance $ 21,263 $ 23,900 (a) Changes in the fair value of earn-out consideration are reported in other operating (income) expense, net in the consolidated statements of income.

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 its 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, foreign currency denominated forecasted cash flows and interest rate risk. 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 during a period of up to 57 months and the forecasted transactions are expected to occur during the same period. 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 March 31, 2018 As of December 31, 2017 As of March 31, 2018 Foreign exchange forward contracts denominated in: United States Dollars (sell) Indian Rupees (buy) $ 1,289,400 $ 1,376,800 $ 54,398 $ 30,002 United States Dollars (sell) Mexican Peso (buy) 9,000 9,000 (441 ) 417 United States Dollars (sell) Philippines Peso (buy) 76,650 66,300 69 (2,858 ) Euro (sell) United States Dollars (buy) 170,542 153,516 (2,069 ) (5,810 ) Pound Sterling (buy) United States Dollars (sell) 24,041 22,150 253 479 Euro (sell) Romanian Leu (buy) 35,826 33,296 (892 ) (448 ) Japanese Yen (sell) Chinese Renminbi (buy) 60,768 54,781 1,918 491 Pound Sterling (sell) United States Dollars (buy) 80,871 67,532 (2,478 ) (5,317 ) Australian Dollars (sell) United States Dollars (buy) 136,092 114,932 (5,180 ) (3,180 ) Interest rate swaps (floating to fixed) 432,117 425,945 9,332 11,568 54,910 25,344 (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 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 revenues 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. Derivative financial instruments (Continued) The fair value of the Company’s derivative instruments and their location in the Company’s financial statements are summarized in the table below: Cash flow hedges Non-designated As of December 31, 2017 As of March 31, 2018 As of December 31, 2017 As of March 31, 2018 Assets Prepaid expenses and other current assets $ 43,557 $ 32,750 $ 4,635 $ 973 Other assets $ 24,906 $ 19,864 $ — $ — Liabilities Accrued expenses and other current liabilities $ 10,092 $ 13,326 $ 254 $ 1,986 Other liabilities $ 7,842 $ 12,931 $ — $ — Cash flow hedges For derivative instruments that are designated and qualify as cash flow hedges, the effective portion of the gain (loss) on the derivative instrument is reported as a component of other comprehensive income (loss) and reclassified into earnings in the same period or periods during which the hedged transaction is recognized in the consolidated statements of income.

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. 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 three months ended March 31, 2017 and 2018 were $4,845 and $7,597, respectively.

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. 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 determining the fair value of options granted in the three months ended March 31, 2017. No options were granted in the three months ended March 31, 2018.

As of March 31, 2018, the total remaining unrecognized stock-based compensation cost for options expected to vest amounted to $5,708, which will be recognized over the weighted average remaining requisite vesting period of 2.7 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 the 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. A summary of RSUs granted during the three months ended March 31, 2018 is set out below: Three months ended March 31, 2018 Number of Restricted Share Units Weighted Average Grant Date Fair Value Outstanding as of January 1, 2018 1,605,251 $ 26.17 Granted — — Vested (Note a) (58,875 ) 23.99 Forfeited (4,500) 24.59 Outstanding as of March 31, 2018 1,541,876 $ 26.26 Expected to vest (Note b) 1,337,172 (a) 6,000 RSUs that vested during the period were net settled upon vesting by issuing 3,576 shares (net of minimum statutory tax withholding). 52,875 RSUs vested in the year ended December 31, 2017, shares in respect of which will be issuable on December 31, 2018 after withholding shares to the extent of minimum statutory withholding taxes. (b) The number of RSUs expected to vest reflects an estimated forfeiture rate. 52,482 RSUs vested in the year ended December 31, 2016, in respect of which 52,055 shares were issued during the three months ended March 31, 2018 after withholding shares to the extent of minimum statutory withholding taxes. 16. Stock-based compensation (Continued) As of March 31, 2018, the total remaining unrecognized stock-based compensation cost related to RSUs amounted to $23,703, which will be recognized over the weighted average remaining requisite vesting period of 2.7 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 plans 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. The ultimate number of shares issued and the related compensation cost recognized is based on a comparison of the final performance metrics to the specified targets. A summary of PU activity during the three months ended March 31, 2018 is set out below: Three months ended March 31, 2018 Number of Performance Units Weighted Average Grant Date Fair Value Maximum Shares Eligible to Receive Outstanding as of January 1, 2018 2,900,940 $ 24.40 2,900,940 Granted — — — Vested (Note a) (1,087,751) 22.73 (1,087,751) Forfeited (78,304 ) 24.92 (78,304 ) Adjustment upon final determination of level of performance goal achievement (Note b) (4,597 ) 25.22 Adjustment upon final determination of level of performance goal achievement (Note b) (4,597 ) Outstanding as of March 31, 2018 1,730,288 $ 25.43 1,730,288 Expected to vest (Note c) 1,524,101 (a) PUs that vested during the period were net settled upon vesting by issuing 691,958 shares (net of minimum statutory tax withholding). (b) Represents an adjustment made in March 2018 to the number of shares subject to the PUs granted in 2017 upon certification of the level of achievement of the performance targets underlying such awards. (c) The number of PUs expected to vest has been adjusted by an estimated forfeiture rate. As of March 31, 2018, the total remaining unrecognized stock-based compensation cost related to PUs amounted to $25,194, which will be recognized over the weighted average remaining requisite vesting period of 1.8 years. 16. Stock-based compensation (Continued) 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, 2018. 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 three months ended March 31, 2017 and 2018, 55,788 and 58,476 common shares, respectively, were issued under the ESPP. The ESPP is considered compensatory under the 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 three months ended March 31, 2017 and 2018 was $141 and $190, respectively, and has been allocated to cost of revenue and selling, general, and administrative expenses.

Capital stock	17. Capital stock 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 contained 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 three months ended March 31, 2017 and March 31, 2018, the Company also purchased 808,293 and 3,015,999 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 three months ended March 31, 2017 and March 31, 2018, $16 and $60, 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, the Company paid a dividend of $0.06 per share, amounting to $11,957 in the aggregate, to shareholders of record as of March 10, 2017. 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 a planned 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, the Company paid a dividend of $0.075 per share, amounting to $14,408 in the aggregate, to shareholders of record as of March 9, 2018.

Earnings Per Share [Abstract]
Earnings per share	18. 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 Company common shares outstanding. The calculation of basic earnings per common share is determined by dividing net income available to common shareholders by the weighted average number of common shares outstanding during the respective periods. Potentially dilutive shares, consisting of outstanding options on common shares, restricted share units, performance units and common shares to be issued under the employee stock purchase plan, have been included in the computation of diluted net earnings per share and the 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 1,003,048 and 660,000 for the three months ended March 31, 2017 and 2018, respectively.

Income Tax Disclosure [Abstract]
Income taxes	24. Income taxes The Company determines its tax provision for interim periods using an estimate of its annual effective tax rate adjusted for discrete items, if any, that are taken into account in the relevant period. Each quarter, the Company updates its estimate of the annual effective tax rate, and if its estimated tax rate changes, the Company makes a cumulative adjustment. The Company’s effective tax rate, or ETR, is 15.7% in the first quarter of 2018. The quarterly tax expense includes certain discrete items recorded in the first quarter amounting to $2,746, resulting in lower tax expense. The Company recognized tax benefits, including deductions for equity-based compensation expenses recorded upon vesting of equity awards (“excess tax benefits”) and employment-related tax deductions in India. The tax benefits were partly offset by the partial expiry of tax holidays in India and changes in jurisdictional mix of income. 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. 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. The Company’s estimate of transition tax on mandatory repatriation introduced under the Tax Act was provisional as of December 31, 2017 and remains provisional as of March 31, 2018 based on information available as of March 31, 2018. The Company has not recorded any tax liability for transition tax as of December 31, 2017 and March 31, 2018 pending the calculation of the earnings and profit pool of its controlled foreign corporations. The Company will recognize any changes to provisional amounts as it refines its estimates and interpretations of the application of the Tax Act. The Company expects to complete its analysis of the provisional items during the second half of 2018. The effects of other provisions of the Tax Act are not expected to have a material impact on the Company’s consolidated financial statements for the quarter ended March 31, 2018. 24. Income taxes (continued) 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. The Company follows the specific identification approach for releasing stranded tax effects from accumulated other comprehensive income (loss) (“AOCI”) upon recognition of these AOCI items in the statement of income. As of December 31, 2017, due to a reduction in the U.S. federal corporate income tax rate under the Tax Act, the Company revalued its net deferred tax assets, including deferred tax liabilities recorded through AOCI. Based on this revaluation, the Company recorded a tax gain of $2,265 relating to derivatives, reducing its net deferred tax liability balance, which was recorded as an income tax benefit in the 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. As of December 31, 2017, the Company had unrecognized tax benefits amounting to $26,060, including an amount of $24,877, which, if recognized, would impact the effective tax rate. The following table summarizes activities related to the Company’s unrecognized tax benefits for uncertain tax positions from January 1, 2018 to March 31, 2018: 2018 Opening balance at January 1 $ 26,060 Increase related to prior year tax positions, including recorded in acquisition accounting 229 Decrease related to prior year tax positions (8 ) Decrease related to prior year tax position due to lapse of applicable statute of limitation (384 ) Effect of exchange rate changes (108) Closing balance at March 31 $ 25,789 The Company’s unrecognized tax benefits as of March 31, 2018 include an amount of $24,604, which, if recognized, would impact the effective tax rate. As of March 31, 2018 and December 31, 2017, the Company had accrued approximately $4,806 and $4,614, respectively, in interest relating to unrecognized tax benefits. During the year ended December 31, 2017 and the three months ended March 31, 2018, the company recognized approximately $(224) and $285, respectively, excluding the impact of exchange rate differences, in interest on unrecognized tax benefits. As of December 31, 2017 and March 31, 2018, the Company had accrued approximately $1,033 and $1,024, respectively, for penalties.

Accordingly, they do not include certain information and note disclosures required by generally accepted accounting principles for annual financial reporting and should be read in conjunction with the consolidated financial statements included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2017. The unaudited interim consolidated financial statements reflect all adjustments that management considers necessary for a fair presentation of the results of operations for these periods. The results of operations for interim periods are not necessarily indicative of results for the full year. The accompanying unaudited interim consolidated 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 on 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 changes 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, determining the nature and timing of satisfaction of performance obligations, determining the standalone selling price of performance obligations, variable consideration, and other obligations for revenue recognition 2. Summary of significant accounting policies (Continued) 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.
Business combinations	(c) 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 acquired individually or with a group of other assets or in a business combination and developed internally 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 Other intangible assets 2-9 years Customer-related intangible assets 1-14 years Marketing-related intangible assets 1-10 years Other intangible assets 2-9 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.
Financial instruments and concentration of credit risk	(d) 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% and 10% of receivables as of December 31, 2017 and March 31, 2018, respectively. GE accounted for 11% and 8% of total revenue for the three months ended March 31, 2017 and 2018, respectively.
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 condition, 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.
Changes in Accounting Policies	(f) 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 Topic 606, Revenue from Contracts with Customers, effective January 1, 2018. As a result, 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 expensed as incurred per the Company’s prior practice. The cumulative impact of the adoption of this standard 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 liability of $5,303
Revenue recognition	2. Summary of significant accounting policies (Continued) Revenue Recognition The Company derives its revenue primarily from business process outsourcing and information technology services, which primarily are provided 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 entity expects to be entitled in exchange for those services. 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 or promised to be delivered to clients or service level agreements that could result in credits or refunds to the customer. 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 has deferred revenue attributable to certain process transition activities, with respect to its customers where such activities do not represent separate performance obligation. 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 generation or enhancement of resources and are expected to be recoverable under the contract and thereby classified as contract cost assets and are 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 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 subscription based licenses is recognized as ratably over the subscription term. All incremental and direct costs incurred for acquiring contracts, such as certain sales commission, are classified as contract cost asset. Such costs are amortized over the expected period of benefit and recorded under Selling, General and Administrative Expenses. Other upfront fees paid to customers are classified as contract asset. Such costs are amortized over the expected period of benefit and recorded as an adjustment to the transaction price and reduced from revenue. Timing of revenue recognition may differ from the timing of invoicing to customers. If payment is received in respect of services prior to the delivery of services, the payment is recognized as an advance from customers and classified as contract liabilities. Contract assets and contract liabilities relating to the same customer contract have been offset and presented on a net basis in the consolidated financial statements. See note 19 for information and related disclosures regarding contract balances. 2. Summary of significant accounting policies (Continued) For a description of the Company’s revenue recognition accounting policy in effect before the Company’s adoption of ASC 606, see Note 3—“Summary of significant accounting policies” under Item 1 —“Financial Statements” and Part II, Item 7—“Management’s Discussion and Analysis of Financial Condition and Results of Operations”—“Critical Accounting Policies and Estimates” in the Company’s Annual Report on Form 10-K for the year ended December 31, 2017. Significant judgements The Company has contracts with customers which often include promises to transfer multiple products and services to the customer. Determining whether products and services are considered distinct performance obligations that should be accounted for separately versus 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. Customer contracts can include incentive payments received for discrete benefits delivered to clients or service level agreements that could result in credits or refunds to the customer. 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.

Recently issued accounting pronouncements	(g) Recently issued and adopted accounting pronouncements The authoritative bodies release standards and guidance which are assessed by management for impact on the Company’s consolidated financial statements. The Company has adopted the following recently released accounting standards: The Company adopted 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 Company has adopted the following recently released accounting 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, 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 2. Summary of significant accounting policies (Continued) ASU requires entities to disclose the income statement lines that contain the other components if they are not presented on appropriately described separate lines. 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. The following recently released accounting standards have not yet been adopted by the Company: In February 2016, the FASB issued ASU No. 2016-02, “Leases.” The core principle of the ASU is that a lessee should recognize the assets and liabilities that arise from its leases other than those that meet the definition of a short-term lease. 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, 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 expects to complete its assessment of adopting ASU No. 2016-02 in the third quarter of 2018. The Company continues to evaluate the impact of its pending adoption of ASU 2016-02 on its consolidated results of operations, cash flows, financial position and disclosures, and the Company’s preliminary assessments are subject to change. In August 2017, the FASB issued ASU 2017-12, “Derivatives and Hedging.” The amendment expands an entity’s ability to 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. The ASU must be adopted using a modified retrospective approach with a cumulative effect adjustment recorded to the opening balance of retained earnings as of the initial application date. The ASU is effective for the Company beginning January 1, 2019, including interim periods in the fiscal year 2019. 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	(h) 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.

(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 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 is classified in level 3 of the fair value hierarchy. See Note 3—Business Acquisitions.
