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, 2016.

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 retained earnings. 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.

2. Summary of significant accounting policies (Continued)

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
Technology-related intangible assets		2-8 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 15% and 11% of receivables as of December 31, 2016 and September 30, 2017, respectively. GE accounted for 15% and 10% of total revenue for the nine months ended September 30, 2016 and 2017, respectively, and 17% and 10% of total revenue for the three months ended September 30, 2016 and 2017, respectively.

2. Summary of significant accounting policies (Continued)

(e) 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 Company has adopted the following recently released accounting standard:

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 will continue to apply 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. As a result, the Company’s income taxes, net income, cash flows, retained earnings, additional paid-in capital, and basic and diluted net income per common share for corresponding periods in 2016 have been restated due to the adoption of ASU No. 2016-09.

In addition, the Company has adopted the following recently released accounting standards. 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 financial statements.

Effective January 1, 2016, the Company adopted FASB ASU 2015-05 (Topic 350), Customer’s Accounting for Fees Paid in a Cloud Computing Arrangement (“ASU 2015-05”), which provides explicit guidance to evaluate the accounting for fees paid by a customer in a cloud computing arrangement. The new guidance clarifies that if a cloud computing arrangement includes a software license, the customer should account for the license consistent with its accounting for other software licenses. If the arrangement does not include a software license, the customer should account for the arrangement as a service contract.

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.

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.

2. Summary of significant accounting policies (Continued)

The following recently released accounting standards have not yet been adopted by the Company:

In May 2014, the FASB issued ASU No. 2014-09, Revenue from Contracts with Customers, which will replace most existing revenue recognition guidance in U.S. GAAP. The core principle of the ASU is that an entity should recognize revenue for the transfer of goods or services equal to the amount that it expects to be entitled to receive for those goods or services. The ASU requires additional disclosure about the nature, amount, timing and uncertainty of revenue and cash flows arising from customer contracts, including significant judgments and changes in judgments. Subsequently, the FASB issued ASU No. 2017-13, in September 2017, ASU No. 2016-08, “Principal versus Agent Considerations (Reporting Gross versus Net),” in March 2016, ASU No. 2016-10, “Identifying performance obligations and licensing,” in April 2016, and ASU 2016-20 “Technical Corrections and Improvements to Topic 606, Revenue from Contracts with Customers” in December 2016, which amend and clarify ASU 2014-09. These ASUs will be effective for the Company beginning January 1, 2018, including interim periods in the fiscal year 2018, and allow for both retrospective and prospective adoption. The Company has performed an initial assessment of the impact of the ASU and developed a transition plan, including necessary changes to policies, processes, and internal controls as well as system enhancements to generate the information necessary for the new disclosures. The implementation plan is on schedule for adoption on January 1, 2018 and the Company will apply the cumulative effect method as its transition approach. The Company expects revenue recognition across the portfolio of services to remain largely unchanged, however there would be an impact on the timing of recognition of certain contract costs, which would now be amortized over the contract period as against being previously expensed off. Based on the analysis completed to date, the Company does not currently expect that the ASU will have a material impact on consolidated revenue in its Consolidated Financial Statements. Company’s preliminary assessments are subject to change.

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 is in the process of determining the method of adoption and assessing the impact of this ASU on its consolidated results of operations, cash flows, financial position and disclosures.

In October 2016, the FASB issued 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. The ASU is effective for the Company beginning January 1, 2018, including interim periods in the fiscal year 2018. Early adoption is permitted. 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 January 2017, the FASB issued 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). The ASU is effective for the Company beginning January 1, 2018, including interim periods in the fiscal year 2018. 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 March 2017, the FASB issued 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 ASU is effective for the Company beginning January 1, 2018, including interim periods in the fiscal year 2018. 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.

2. Summary of significant accounting policies (Continued)

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.

(f) 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.

(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 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 and nine months ended September 30, 2016 and 2017:

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 51 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, 2016		As of September 30, 2017		As of December 31, 2016			As of September 30, 2017

(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 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.

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. Gains (losses) on the derivatives, representing either hedge ineffectiveness or hedge components excluded from the assessment of effectiveness, are recognized in earnings as incurred.

In connection with cash flow hedges, the gains (losses) recorded as a component of other comprehensive income (loss), or OCI, and the related tax effects are summarized below:

During the nine months ended September 30, 2016, the Company tested an intangible software asset for recoverability as a result of a downward revision to the forecasted cash flows to be generated by the intangible asset. The Company previously recorded a charge to this asset in the third quarter of 2015. Based on the results of its testing, the Company determined that the carrying value of the intangible asset exceeded the estimated undiscounted cash flows by $10,324 and recorded an additional charge to further reduce the carrying value by this amount. Of this charge, $5,381 was recorded during the three months ended September 30, 2016. The Company used a combination of the income and cost approaches to determine the fair value of the intangible asset for the purpose of calculating the charge. This charge has been recorded in other operating (income) expenses, net in the consolidated statement of income. During the nine months ended September 30, 2016, the Company also tested a customer-related intangible asset for recoverability as a result of the termination of a client contract. Based on results of such testing, the Company recorded a charge in the amount of the asset’s total carrying value of $871.

As of December 31, 2016 and September 30, 2017, the limits available were $15,382 and $14,698, respectively, of which $10,980 and $7,395 was utilized, constituting non-funded drawdown.

(b)

A fund-based and non-fund based revolving credit facility of $350,000, which the Company obtained in June 2015 as described in note 12. This facility replaced the Company’s $250,000 facility initially entered into in August 2012 and subsequently amended in June 2013. As of both December 31, 2016 and September 30, 2017, a total of $160,978 was utilized, of which $160,000 constituted funded drawdown and $978 constituted non-funded drawdown.

12. Long-term debt

In June 2015, the Company refinanced its 2012 credit facility through a new credit facility comprised of an $800,000 term loan and a $350,000 revolving credit facility. Borrowings under the new facility bear interest at a rate equal to, at the election of the Company, either LIBOR plus an applicable margin equal to 1.50% per annum or a base rate plus an applicable margin equal to 0.50% per annum, 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 1.50% per annum. As a result of the June 2015 refinancing, the gross outstanding term loan under the previous facility, which amounted to $663,188 as of June 30, 2015, was extinguished, and the Company expensed $10,050, representing accelerated amortization of the existing unamortized debt issuance costs related to the prior facility. Additionally, the refinancing of the revolving facility resulted in the accelerated amortization of $65 relating to the existing unamortized debt issuance cost. The remaining unamortized costs for the revolving facility, together with the fees paid to the Company’s lenders and third parties in connection with the new term loan and revolving facility, will be amortized over the term of the refinanced facility, which ends on June 30, 2020. During the nine months ended September 30, 2017, the Company was in compliance with the financial covenants of the credit agreement.

As of December 31, 2016 and September 30, 2017, the amount outstanding under the term loan, net of debt amortization expense of $2,667 and $2,051, was $737,333 and $707,967, respectively. As of December 31, 2016 and September 30, 2017, the term loan bore interest at a rate equal to LIBOR plus a margin of 1.50% per annum based on the Company’s election and current credit rating. Indebtedness under the refinanced facility is unsecured. The amount outstanding on the term loan as of September 30, 2017 will be repaid through quarterly payments of $10,000, and the balance will be repaid upon the maturity of the term loan on June 30, 2020.

The maturity profile of the term loan, net of debt amortization expense, is as follows:

Year ended	Amount
2017	$	9,815
2018		39,226
2019		39,272
2020		619,654
Total	$	707,967

In March 2017, the Company issued $350,000 aggregate principal amount of 3.70% senior notes in a private offering, resulting in cash proceeds of approximately $348,519, net of an underwriting fee of $1,481. In connection with the offering, the Company incurred other debt issuance costs of $1,161. The total debt issuance cost of $2,642 is being amortized over the life of the notes as additional interest expense. As of September 30, 2017, the amount outstanding under the notes, net of debt amortization expense of $2,372, was $347,628, which is payable on April 1, 2022. The Company 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. Upon certain change of control transactions, the Company 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%. The Company is required to offer to exchange the notes for registered notes or have one or more shelf registration statements declared effective within 455 days after the issue date of the notes and, if such exchange offer fails to be consummated or such registration statement fails to be effective by June 25, 2018, then the interest payable on the notes will increase by 0.25% per annum during the 90-day period immediately following such date and will further increase by 0.25% per annum at the end of each subsequent 90-day period up to a maximum increase of 0.50%. The notes are senior unsecured obligations of the Company and will rank equally with all other senior unsecured indebtedness of the Company outstanding from time to time.

Stock-based compensation

16. Stock-based compensation

The Company has issued options under the Genpact Global Holdings 2005 Plan (the “2005 Plan”), the Genpact Global Holdings 2006 Plan (the “2006 Plan”), the Genpact Global Holdings 2007 Plan (the “2007 Plan”) and the Genpact Limited 2007 Omnibus Incentive Compensation Plan (the “2007 Omnibus Plan”) to eligible persons, who are employees, directors and certain other persons associated with the Company.

With respect to options granted under the 2005, 2006 and 2007 Plans before the date of adoption of the 2007 Omnibus Plan, if an award granted under any such plan was forfeited or otherwise expired, terminated, or cancelled without the delivery of shares, then the shares covered by the forfeited, expired, terminated, or cancelled award were added to the number of shares otherwise available for grant under the respective plans.

Under the 2007 Omnibus Plan, share-based awards forfeited, expired, terminated, or cancelled under any of the 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 further grants may be made under the 2007 Omnibus Plan after the date of adoption of the 2017 Omnibus Plan.

Stock-based compensation costs relating to the foregoing plans during the nine months ended September 30, 2016 and 2017 were $18,046 and $21,985, respectively, and for the three months ended September 30, 2016 and 2017 were $4,718 and $9,907, respectively. These costs have been allocated to cost of revenue and selling, general, and administrative expenses.

Stock options

Options granted are subject to a vesting requirement. Options granted under the plans to date 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 the compensation cost over the vesting period of the option. Compensation cost is determined as of 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 the nine months ended September 30, 2016 and September 30, 2017.

	Nine months ended September 30, 2016	Nine months ended September 30, 2017
Dividend yield	—			0.97%
Expected life (in months)	84			84
Risk-free rate of interest	1.42%-1.56%		2.25%

As of September 30, 2017, the total remaining unrecognized stock-based compensation cost for options expected to vest amounted to $8,182, 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 Company common share at a future date. The fair value of each RSU is typically the closing market price of a Company common share on the date of the grant. 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 nine months ended September 30, 2017 is set out below:

	Nine months ended September 30, 2017
	Number of Restricted Share Units			Weighted Average Grant Date Fair Value
Outstanding as of January 1, 2017		117,905		$	20.65

Outstanding as of September 30, 2017		1,589,980		$	26.11
Expected to vest (Note b)		1,324,508

(a)	RSUs that vested during the period were net settled upon vesting by issuing 32,395 shares (net of minimum statutory tax withholding).

(b)	The number of RSUs expected to vest reflects an estimated forfeiture rate.

53,546 RSUs vested in the year ended December 31, 2015, in respect of which 53,023 shares were issued during the nine months ended September 30, 2017 after withholding shares to the extent of minimum statutory withholding taxes.

34,035 RSUs vested in the year ended December 31, 2016, in respect of which 17,802 shares were issued during the nine months ended September 30, 2017 after withholding shares to the extent of minimum statutory withholding taxes.

16. Stock-based compensation (Continued)

As of September 30, 2017, the total remaining unrecognized stock-based compensation cost related to RSUs amounted to $29,339, which will be recognized over the weighted average remaining requisite vesting period of 3.1 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 Company 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 closing 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 Company’s plans to date are subject to cliff vesting. The compensation expense for such awards is recognized on a straight-line basis over the vesting terms. Over the performance period, the number of shares to be issued is adjusted upward or downward depending on 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 nine months ended September 30, 2017 is set out below:

	Nine months ended September 30, 2017
	Number of Performance Units			Weighted Average Grant Date Fair Value		Maximum Shares Eligible to Receive

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”).

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 nine months ended September 30, 2016 and 2017, 105,856 and 150,265 common shares, respectively, were issued under the ESPP.

The ESPP is considered compensatory under the FASB guidance on Compensation-Stock Compensation.

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. The Company paid the aggregate purchase price to the Dealer and received an initial delivery of 6,578,947 common shares at a price of $24.32 per share. The purchase price was recorded as a reduction in shareholders’ equity through a $160,000 decrease in retained earnings and a $40,000 decrease in additional paid-in capital. The final settlement of the transaction under the ASR agreement, which was initially expected to be completed by the end of the fourth quarter of 2017, is now expected to be completed in January 2018 pursuant to an amendment to the ASR agreement. The final number of common shares to be repurchased by the Company under the ASR agreement will be based on the volume-weighted average share price of the Company’s common shares during the term of the applicable transaction, less a discount and subject to adjustments pursuant to the terms of the ASR agreement. At settlement, under certain circumstances, the Company may be entitled to receive additional common shares from the Dealer or may be required either to deliver its common shares or to make a cash payment to the Dealer. 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 nine months ended September 30, 2016, the Company purchased 9,615,323 of its common shares on the open market at a weighted average price of $25.23 per share for an aggregate cash amount of $242,552. During the nine months ended September 30, 2017, the Company made payments in an aggregate cash amount of $219,784 toward share repurchases. Of this amount, the Company paid (i) $19,784 to repurchase 808,293 of its common shares on the open market at a weighted average price of $24.48 per share, (ii) $160,000 to the Dealer for the initial delivery of 6,578,947 of its common shares under the ASR agreement at a weighted average price of $24.32 per share, and (iii) $40,000 to the Dealer for shares to be delivered at the final settlement of the transaction under the ASR agreement as described above. All repurchased shares have been retired. 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 nine months ended September 30, 2016 and September 30, 2017, $192 and $16, 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 intends to pay a regular quarterly cash dividend of $0.06 per share to holders of its common shares, representing a planned annual dividend of $0.24 per share. On March 28, 2017, June 28, 2017 and September 21, 2017, the Company paid dividends of $0.06 per share, amounting to $11,957, $11,558 and $11,581 in the aggregate, to shareholders of record as of March 10, 2017, June 12, 2017 and September 8, 2017 respectively.

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 698,286 and 1,122,559 for the nine months ended September 30, 2016 and 2017, respectively, and 947,778 and 1,113,307 for the three months ended September 30, 2016 and 2017, respectively.

[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]	Included in accrued expenses and other current liabilities and other liabilities in the consolidated balance sheets.
[4]	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.
[5]	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.
