	1. Organization
	Nature of Operations
	The Company is a global leader in designing, transforming and running business processes and operations, including those that are complex and industry-specific. The Company’s mission is to help clients become more competitive by making their enterprises more intelligent through becoming more adaptive, innovative, globally effective and connected to their own clients. Genpact stands for Generating Impact – visible in better management of risk, regulations, costs and growth for hundreds of long-term clients, including more than 100 of the Fortune Global 500. The Company’s approach is distinctive – it offers an unbiased, agile combination of smarter processes, crystallized in its Smart Enterprise Processes (SEPSM) proprietary framework, along with analytics and technology, which limits upfront investments and enhances future adaptability. The Company has 66,000+ employees in 25 countries with key management and corporate offices in New York City. Behind the Company’s single-minded passion for process and operational excellence is the Lean and Six Sigma heritage of a former General Electric division that has served GE businesses for more than 16 years.
	Prior to December 30, 2004, the business of the Company was conducted through various entities and divisions of the General Electric Company (“GE”). On December 30, 2004, in a series of transactions referred to as the “2004 Reorganization,” GE transferred such operations to the Company. In August 2007, the Company completed an initial public offering of its common shares, pursuant to which the Company and certain of its existing shareholders each sold 17,647,059 shares. On March 24, 2010, the Company completed a secondary offering of its common shares pursuant to which GE’s shareholding in the Company decreased to 9.1% and it ceased to be a significant shareholder, although it continued to be a related party. During the year ended December 31, 2012, GE’s shareholding declined to less than 5.0%, as a result of which GE is no longer considered a related party.
	On December 14, 2012, a secondary offering of the Company’s common shares by affiliates of General Atlantic (“GA”) and Oak Hill Capital Partners (“OH”) was completed. Upon the completion of the secondary offering, GA and OH each owned approximately 2.4% of the Company’s common shares outstanding, and they ceased to be significant shareholders and related parties.
	2012 Recapitalization
	On August 1, 2012, affiliates of GA and OH entered into an agreement to sell 67,750,678 common shares of the Company to Glory Investments A Limited, formerly known as South Asia Private Investments, an affiliate of Bain Capital Investors, LLC (“Bain Capital”). On October 25, 2012, Bain Capital and its affiliated assignees, along with two additional co-investors (RGIP, LLC, an investor in certain investment funds which are affiliated with Bain Capital, and Twickenham Investment Private Limited, an affiliate of the Government of Singapore Investment Corporation Private Limited), completed the purchase of the Company common shares covered by the share purchase agreement.
	On August 30, 2012, the Company terminated its previous credit facility of $380,000 and entered into a new credit facility of $925,000. Net proceeds from the credit facility along with cash on hand were partially used to fund the payment of a special cash dividend in the amount of $2.24 per share, or $501,620 in aggregate, which was declared by the Company’s board of directors on August 30, 2012, and paid on September 24, 2012 to holders of record as of September 10, 2012. The share purchase transaction described above, the entry into a new credit facility and the payment of the special cash dividend are referred to collectively as the “2012 Recapitalization.”

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, 2013.
	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 the interim periods are not necessarily indicative of the 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 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.
	The noncontrolling interest disclosed in the accompanying unaudited interim consolidated financial statements represents the noncontrolling partners’ interest in the operation of Genpact Netherlands B.V. and the profits or losses associated with such noncontrolling interest. The noncontrolling partners of Genpact Netherlands B.V. are individually liable for the tax obligations on their shares of profit as it is a partnership and, accordingly, noncontrolling interest relating to Genpact Netherlands B.V. has been computed prior to tax and disclosed accordingly in the unaudited interim 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, the carrying amount of property, plant and equipment, intangibles and goodwill, reserves for doubtful receivables, valuation allowances for deferred tax assets, the valuation of derivative financial instruments, measurements of stock-based compensation, assets and obligations related to employee benefits, and income tax uncertainties and other contingencies. Management believes that the estimates used in the preparation of the consolidated financial statements are reasonable. Although these estimates are based upon management’s best knowledge of current events and actions, actual results could differ from these estimates. Any changes in estimates are adjusted prospectively in the Company’s consolidated financial statements.
	(c) Business combinations, goodwill and other intangible assets
	The Company accounts for its business combinations by recognizing the identifiable tangible and intangible assets acquired and liabilities assumed, and any noncontrolling 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 the 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 the reporting unit exceeds the fair value of that goodwill, an impairment loss is recognized in an amount equal to the excess. In addition, the Company performs the 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 the reporting unit below its carrying amount. See Note 9 for information and related disclosures.
	Intangible assets acquired individually or with a group of other assets or in a business combination are carried at cost less accumulated amortization based on their estimated useful lives as follows:
	Customer-related intangible assets		1-14 years
	Marketing-related intangible assets		1-10 years
	Contract-related intangible assets		1 year
	Other intangible assets		3-9 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, short term deposits, 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 28% and 25% of receivables as of December 31, 2013 and June 30, 2014, respectively. GE accounted for 23% and 21% of revenues for the six months and three months ended June 30, 2013 and 2014, respectively.
	(e) Recently 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 following recently released accounting standards have been adopted by the Company. Adoption of these standards did not have a material impact on the Company’s consolidated results of operations, cash flows, financial position or disclosures:
		•	Effective January 1, 2014, the Company adopted FASB ASU 2013-05, Foreign Currency Matters (Topic 830): Parent’s Accounting for the Cumulative Translation Adjustment upon De-recognition of Certain Subsidiaries or Groups of Assets within a Foreign Entity or of an Investment in a Foreign Entity (“ASU 2013-05”). This new guidance requires that the parent release any related cumulative translation adjustment into net income only if the sale or transfer results in the complete or substantially complete liquidation of the foreign entity in which the subsidiary or group of assets had resided.
		•	Effective January 1, 2014, the Company adopted FASB ASU 2013-11, Income Taxes (Topic 740): Presentation of an Unrecognized Tax Benefit When a Net Operating Loss Carryforward, a Similar Tax Loss, or a Tax Credit Carryforward Exists (“ASU 2013-11”). This new guidance requires an entity to present an unrecognized tax benefit, or a portion of an unrecognized tax benefit, as a reduction to a deferred tax asset for a net operating loss carryforward, a similar tax loss, or a tax credit carryforward, except as follows: to the extent a net operating loss carryforward, a similar tax loss, or a tax credit carryforward is not available at the reporting date under the tax law of the applicable jurisdiction to settle any additional income taxes that would result from the disallowance of a tax position or the tax law of the applicable jurisdiction does not require the entity to use, and the entity does not intend to use, the deferred tax asset for such purpose, the unrecognized tax benefit should be presented in the financial statements as a liability and should not be combined with deferred tax assets.
	(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.

	A. Acquisitions
	Pharmalink Consulting Limited and Pharmalink Consulting Inc.
	On May 29, 2014, the Company acquired 100% of the outstanding equity interest in each of Pharmalink Consulting Limited, a company incorporated under the laws of England and Wales, and Pharmalink Consulting Inc., a California corporation, (collectively referred to as “Pharmalink”) for cash consideration of $126,483, subject to adjustment for net debt and working capital. The acquisition agreement provides for contingent earn-out consideration (ranging from $0 to $27,405) which had an estimated fair value of $12,730 as of the acquisition date, based on gross profits and order bookings of sustainable outsourcing contracts for the period from June 1, 2014 to June 30, 2016. The total consideration paid at closing for the Company’s acquisition of Pharmalink was $123,701, net of cash acquired of $2,200.
	Pharmalink is a provider of regulatory affairs services to the life sciences industry. With this acquisition, the Company adds regulatory consulting, outsourcing and operations capabilities for clients in the life sciences industry.
	The acquisition of Pharmalink has been accounted for under the acquisition method of accounting in accordance with ASC 805, Business Combinations. The assets and liabilities of Pharmalink are recorded at fair value as of the date of the acquisition. As of the date of these financial statements, the purchase consideration and the allocation for the acquisition are pending final adjustment for working capital and net debt in accordance with the terms of acquisition agreement. The preliminary estimated purchase consideration for Pharmalink is $138,631 including the fair value of earn-out consideration and a preliminary adjustment for working capital and net debt. Further, the Company is evaluating certain tax positions with respect to this acquisition which, when determined, may result in the recognition of additional assets and liabilities as of the acquisition date. Changes to the preliminary recorded assets and liabilities may result in a corresponding adjustment to goodwill. The measurement period will not exceed one year from the acquisition date.
	The following table summarizes the preliminary allocation of the preliminary estimated purchase price based on the fair value of the assets acquired and the liabilities assumed as of the date of acquisition:
	Preliminary estimated purchase price	$	138,631
	Acquisition related costs included in selling, general and administrative expenses as incurred		1,977
	Recognized amounts of identifiable assets acquired and liabilities assumed
	Net assets acquired (excluding intangible assets and deferred tax asset/(liability), net)		7,174
	Intangible assets		29,923
	Deferred tax asset/(liability), net		(8,419	)
	Total identifiable net assets acquired		28,678
	Goodwill	$	109,953
	Total	$	138,631
	The fair value of the net assets acquired includes trade receivables with a fair value of $11,897. The gross amount due is $12,075, of which $178 is expected to be uncollectible. Goodwill, representing the excess of the preliminary estimated purchase price over the net assets acquired, has been allocated to the India reporting unit and is not deductible for tax purposes. The amortizable intangible assets acquired are being amortized over their estimated useful lives using a method of amortization that reflects the expected pattern in which the economic benefits of the intangible assets will be consumed or otherwise realized. The intangible assets consist of customer related and marketing related intangible assets with a weighted average amortization period of 6 years.
	The results of operations of Pharmalink and the fair value of its assets and liabilities are included in the Company’s Consolidated Financial Statements with effect from May 29, 2014, the date of acquisition.
	B. Earn-out consideration
	The terms of the acquisition agreements for certain business acquisitions provided for payment of additional earn-out consideration if certain future events or conditions are met. These earn-outs were recorded as liabilities based on their fair values as of the acquisition dates. The Company evaluates the fair value of earn-out consideration for the respective acquisitions for changes at each reporting period and records the corresponding changes in “Other operating (income) expense, net” in the Consolidated Statements of Income. The company recorded a decrease in the fair value of earn-out consideration for the three months ended June 30, 2013 and June 30, 2014 of $2,324 and $556 respectively, and for the six months ended June 30, 2013 and June 30, 2014 of $2,271 and $2,198 respectively.

	The Company is exposed to the risk of rate fluctuations on foreign currency assets and liabilities and foreign currency denominated forecasted cash flows. The Company has established risk management policies, including the use of derivative financial instruments to hedge foreign currency assets and liabilities and foreign currency denominated forecasted cash flows. These derivative financial instruments are largely deliverable and non-deliverable forward foreign exchange contracts. The Company enters into these contracts with counterparties which are banks or other financial institutions, and the Company considers the risk of non-performance by the counterparties not to be material. The forward foreign exchange contracts mature between zero and sixty-six 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:

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 statement of financial position. In accordance with the FASB guidance on Derivatives and Hedging, the Company designates foreign exchange forward contracts as cash flow hedges for forecasted revenues and the purchase of services. In addition to this program, the Company has 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 denominated in currencies other than the underlying functional currency.

As of December 31, 2013 and June 30, 2014, a total of $4,397 and $177,224, respectively, was utilized, of which $0 and $175,000, respectively, constituted funded drawdown and $4,397 and $2,224, respectively, constituted non-funded drawdown. This facility expires in August 2017. The funded drawdown amount bears interest at LIBOR plus a margin of 2.50% as of both December 31, 2013 and June 30, 2014. The unutilized amount on the facility bears a commitment fee of 0.50%. Indebtedness under these facilities is secured by certain assets of the Company, and the credit agreement contains certain covenants, including a maximum leverage covenant that becomes effective only if the revolving facility is drawn for $50,000 or more. During the six months ended June 30, 2014, the Company was in compliance with all of the financial covenants.

	11. Long-term debt
	In August 2012, the Company obtained credit facilities aggregating $925,000 from a consortium of financial institutions to (i) finance the repayment of the balance outstanding under the previous credit facility of $380,000, (ii) fund a portion of its special cash dividend, and (iii) for general corporate purposes of the Company and its subsidiaries, including working capital requirements. The credit agreement provides for a term loan of $675,000 and a revolving credit facility of $250,000.
	In June 2013, the Company amended this credit facility. Under the amended facility, the applicable margin on the term loan and the revolving credit facility was reduced from 3.25% p.a. to 2.75% p.a. and 2.50% p.a., respectively. In addition, the LIBOR floor on the term loan was reduced from 1% to 0.75%. As of the amendment date, the gross outstanding term loan amounted to $671,625. The amendment did not result in a substantial modification of $553,589 of the outstanding term loan under the previous credit facility. In connection with the amendment, the Company extinguished $118,036 of the outstanding term loan under the previous credit facility amounting to $118,036 and obtained additional funding amounting to $121,410, increasing the total term loan outstanding to $675,000. As a result, the Company expensed $3,103, which represented a partial acceleration of the amortization of the existing unamortized debt issuance costs and an additional fee paid to the lenders in respect of the extinguished amount. The overall borrowing capacity under the revolving facility did not change. The amendment of the revolving facility resulted in the accelerated amortization of $54 relating to an existing unamortized debt issuance cost. The remaining unamortized costs and an additional third-party fee paid in connection with the amendment of the term loan and revolving facility will be amortized over the term of the term loan and revolving facility, which end on August 30, 2019 and August 30, 2017, respectively.
	As of December 31, 2013 and June 30, 2014, the outstanding term loan, net of debt amortization expense of $13,761 and $12,524, was $657,864 and $655,726, respectively. As of December 31, 2013 and June 30, 2014, the term loan bears interest at LIBOR (LIBOR floor of 0.75%) plus an applicable margin of 2.75% p.a. Indebtedness under the loan agreement is secured by certain assets of the Company. The amount outstanding on the term loan as of June 30, 2014 will be repaid through quarterly payments of 0.25% of the principal amount of $675,000, and the balance will be repaid upon the maturity of the term loan on August 30, 2019.
	The maturity profile of the term loan, net of debt amortization expense, is as follows:

Stock-based compensation	'
	13. 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 of the Plans is forfeited or otherwise expires, terminates, or is cancelled without the delivery of shares, then the shares covered by the forfeited, expired, terminated, or cancelled award will be added to the number of shares otherwise available for grant under the respective Plans.
	From the date of adoption of the 2007 Omnibus Plan on July 13, 2007, the options forfeited, expired, terminated, or cancelled under any of the plans will be 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 August 30, 2012, the Company’s Board of Directors declared a special cash dividend of $2.24 per share. The special cash dividend resulted in an adjustment to stock-based awards under both the 2007 Omnibus Plan and the 2005 Plan. Accordingly, effective September 24, 2012, the payment date of the special cash dividend, the number of common shares authorized for issuance under the 2007 Omnibus Plan was increased by 2,544,327 shares. The number of common shares authorized for issuance under the 2005 Plan was increased by 495,915 shares.
	Further, as of December 31, 2012, the number of common shares authorized for issuance under the 2007 Omnibus Plan had been increased by 6,314,496 shares as a result of the termination, expiration or forfeiture of options granted under the Company’s stock incentive plans other than the 2007 Omnibus Plan. In accordance with the anti-dilutive provisions of the 2005 Plan, 2006 Plan, 2007 Plan and 2007 Omnibus Plan, the Company adjusted both the exercise price and the number of stock-based awards outstanding as of the record date of the special cash dividend. The aggregate fair value, intrinsic value and the ratio of the exercise price to the market price were approximately equal immediately before and after the adjustments. Therefore, in accordance with the equity restructuring guidance under ASC 718, Compensation-Stock Compensation, no incremental compensation expense was recognized for the adjustment to the outstanding stock-based awards as a result of the special cash dividend.
	Stock-based compensation costs relating to the foregoing plans during the six months ended June 30, 2013 and 2014 were $16,503 and $11,735, respectively, and for the three months ended June 30, 2013 and 2014 were $10,022 and $6,834, respectively. These costs have been allocated to cost of revenue and selling, general, and administrative expenses.

	As of June 30, 2014, the total remaining unrecognized stock-based compensation cost for options expected to vest amounted to $21,080, which will be recognized over the weighted average remaining requisite vesting period of 3.5 years.
	Restricted Share Units
	The Company has granted restricted share units, or RSUs, under the 2007 Omnibus Plan. Each RSU represents the right to receive one common share at a future date. 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 six 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 six months ended June 30, 2014 is set out below:

	61,057 RSUs vested in the year ended December 31, 2013, the shares in respect of which are issuable on December 31, 2014 after withholding shares to the extent of the minimum statutory withholding taxes.
	As of June 30, 2014, the total remaining unrecognized stock-based compensation cost related to RSUs amounted to $7,516, which will be recognized over the weighted average remaining requisite vesting period of 1.3 years.
	Performance Units
	The Company has granted stock awards in the form of Performance Units, or PUs, under the 2007 Omnibus Plan. 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. The PUs granted under the plan are subject to cliff or graded vesting. For awards with cliff vesting, the compensation expense is recognized on a straight-line basis over the vesting terms, and for awards with graded vesting, the compensation expense is recognized over the vesting term of each separately vesting portion. Over the performance period, 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 as an expense will be based on a comparison of the final performance metrics to the specified targets.

697,853 and 432 shares, including the additional awards, were issued in March 2014 and April 2014 with respect to grants made in March 2011, and 77,619 shares, including the additional awards, were issued in March 2014 with respect to grants made in June 2011, after withholding shares to the extent of the minimum statutory withholding taxes.
**	Includes 251,427 shares underlying PUs granted in May 2011, 1,244,507 shares underlying PUs granted in March 2013 and 630,000 shares underlying PUs granted in May 2013, all of which were forfeited due to non-fulfillment of the performance conditions as certified by the compensation committee based on the Company’s audited financial statements.
***	Represents a reduction of 333,002 and 39,285 of the maximum shares eligible to vest for PUs granted in March 2011 and June 2011, respectively, as a result of the compensation committee’s certification of the level of achievement of the performance conditions based on the Company’s audited financial statements. Also includes a reduction of 616,568 shares for grants made in March 2013, 985,500 shares for grants made in May 2013 and 121,000 shares for grants made in May 2011, due to non-fulfillment of the performance conditions as certified by the compensation committee based on the Company’s audited financial statements.
For the PUs granted in August 2010, vesting for the year ended December 31, 2012 took place at 122.2% of the target shares, or 231,029 shares, based on the compensation committee’s certification of achievement of the performance goals for the performance period based on the Company’s audited consolidated financial statements. 138,035 shares underlying such PUs were issued in January 2014 after withholding shares to the extent of the minimum statutory withholding taxes.
As of June 30, 2014, the total remaining unrecognized stock-based compensation costs related to PUs amounted to $23,502, which will be recognized over the weighted average remaining requisite vesting period of 2.2 years.
Under the 2007 Omnibus Plan, the definition of change of control includes the acquisition by any person, corporation or other entity or group other than GA, OH, GE or any of their affiliates of 25% or more of the voting securities of the Company. The purchase by Bain Capital of Company shares from GA and OH would have constituted a change of control under the 2007 Omnibus Plan resulting in (1) accelerated vesting of the PUs granted in August 2010 to the former CEO (who since assumed the role of Non-Executive Vice-Chairman) and the PUs granted to the Company’s Chief Executive Officer in June 2011 and March 2012, (2) “double-trigger” vesting of the outstanding PUs granted in March 2010 and March 2011 based on an abbreviated performance period ending with the close of the Company’s fiscal quarter coincident with or immediately preceding the effective date of the Change of Control in the event of a termination without cause in the twenty-four months following a change of control and (3) “double-trigger” vesting of the outstanding PUs granted in March 2012 based on target performance in the event of a termination without cause in the twenty-four months following a change of control. Because the Board of Directors determined that Bain Capital’s purchase of Company shares from GA and OH was not the type of transaction intended to constitute a change of control, it amended the 2007 Omnibus Plan to provide that the contemplated transaction among Bain Capital, GA and OH would not constitute a change of control thereunder. In addition, the CEO and Non-Executive Vice-Chairman waived any accelerated vesting of their PUs and the affected employees consented to the amendment of the change of control definition. As a result of the foregoing, all such PUs will continue to vest in accordance with their original terms.
The amendment to the 2007 Omnibus Plan constituted a modification to the PUs effective as of October 25, 2012, as a result of which 123 employees were affected and an incremental compensation cost of $5,500 was determined and will be recognized over a weighted average period of 1.85 years. The incremental compensation cost due to this modification was a result of considering the original performance period in determining expected vesting as against the abbreviated performance period for 2010 and 2011 grants and vesting at target for 2012 performance grants.
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 deduction at 90% of the fair value of a Company common share on the last business day of each purchase interval. The dollar amount of common shares purchased under the ESPP must not exceed the greater of 15% of the participating employee’s base salary or $25 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 in the subsequent May, August, November and February of each year. 4,200,000 common shares have been reserved for issuance in the aggregate over the term of the ESPP.
During the six months ended June 30, 2013 and 2014, 53,671 and 77,556 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 employee stock purchase plan is recognized in accordance with the FASB guidance on Compensation-Stock Compensation. The compensation expense for the ESPP during the six months ended June 30, 2013 and 2014 was $116 and $144, respectively, and for the three months ended June 30, 2013 and 2014 was $71 and $72, respectively, and has been allocated to cost of revenue and selling, general, and administrative expenses.

	The Company calculates earnings per share in accordance with FASB guidance on Earnings per Share. Basic and diluted earnings per common share give effect to the change in the number of common shares of the Company outstanding. The calculation of basic earnings per common share was determined by dividing net income available to common shareholders by the weighted average number of common shares outstanding during the respective periods. The potentially dilutive shares, consisting of outstanding options on common shares, restricted share units, performance units and common shares to be issued under the ESPP have been included in the computation of diluted net earnings per share and the weighted average number of 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 1,749,000 and 3,416,262 for the six months ended June 30, 2013 and 2014, respectively, and 3,483,000 and 3,452,761 for the three months ended June 30, 2013 and 2014, respectively.

Summary_of_Significant_Account1

Summary of Significant Accounting Policies (Policies)	6 Months Ended
	Jun. 30, 2014
Basis of preparation and principles of consolidation	'
	(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, 2013.
	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 the interim periods are not necessarily indicative of the 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 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.
	The noncontrolling interest disclosed in the accompanying unaudited interim consolidated financial statements represents the noncontrolling partners’ interest in the operation of Genpact Netherlands B.V. and the profits or losses associated with such noncontrolling interest. The noncontrolling partners of Genpact Netherlands B.V. are individually liable for the tax obligations on their shares of profit as it is a partnership and, accordingly, noncontrolling interest relating to Genpact Netherlands B.V. has been computed prior to tax and disclosed accordingly in the unaudited interim 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, the carrying amount of property, plant and equipment, intangibles and goodwill, 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.
Business Combinations	'
	(c) Business combinations, goodwill and other intangible assets
	The Company accounts for its business combinations by recognizing the identifiable tangible and intangible assets acquired and liabilities assumed, and any noncontrolling 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 the 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 the reporting unit exceeds the fair value of that goodwill, an impairment loss is recognized in an amount equal to the excess. In addition, the Company performs the 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 the reporting unit below its carrying amount. See Note 9 for information and related disclosures.
Intangible Assets	'
	Intangible assets acquired individually or with a group of other assets or in a business combination are carried at cost less accumulated amortization based on their estimated useful lives as follows:
	Customer-related intangible assets		1-14 years
	Marketing-related intangible assets		1-10 years
	Contract-related intangible assets		1 year
	Other intangible assets		3-9 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, short term deposits, 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 28% and 25% of receivables as of December 31, 2013 and June 30, 2014, respectively. GE accounted for 23% and 21% of revenues for the six months and three months ended June 30, 2013 and 2014, respectively.
Recently adopted accounting pronouncements	'
	(e) Recently 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 following recently released accounting standards have been adopted by the Company. Adoption of these standards did not have a material impact on the Company’s consolidated results of operations, cash flows, financial position or disclosures:
		•	Effective January 1, 2014, the Company adopted FASB ASU 2013-05, Foreign Currency Matters (Topic 830): Parent’s Accounting for the Cumulative Translation Adjustment upon De-recognition of Certain Subsidiaries or Groups of Assets within a Foreign Entity or of an Investment in a Foreign Entity (“ASU 2013-05”). This new guidance requires that the parent release any related cumulative translation adjustment into net income only if the sale or transfer results in the complete or substantially complete liquidation of the foreign entity in which the subsidiary or group of assets had resided.
		•	Effective January 1, 2014, the Company adopted FASB ASU 2013-11, Income Taxes (Topic 740): Presentation of an Unrecognized Tax Benefit When a Net Operating Loss Carryforward, a Similar Tax Loss, or a Tax Credit Carryforward Exists (“ASU 2013-11”). This new guidance requires an entity to present an unrecognized tax benefit, or a portion of an unrecognized tax benefit, as a reduction to a deferred tax asset for a net operating loss carryforward, a similar tax loss, or a tax credit carryforward, except as follows: to the extent a net operating loss carryforward, a similar tax loss, or a tax credit carryforward is not available at the reporting date under the tax law of the applicable jurisdiction to settle any additional income taxes that would result from the disallowance of a tax position or the tax law of the applicable jurisdiction does not require the entity to use, and the entity does not intend to use, the deferred tax asset for such purpose, the unrecognized tax benefit should be presented in the financial statements as a liability and should not be combined with deferred tax assets.
Reclassification	'
	(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.
