Organization [Abstract]
Organization	1. Organization (a) Nature of Operations The Company is a global leader in business process and technology management services, leveraging the power of smarter processes, smarter analytics and smarter technology to help its clients drive intelligence across the enterprise. The Company believes that its Smart Enterprise Processes (SEP^SM) framework, its unique science of process combined with deep domain expertise in multiple industry verticals, leads to superior business outcomes. The Company's Smart Decision Services deliver valuable business insights to its clients through targeted analytics, re-engineering expertise, and advanced risk management. Making technology more intelligent by embedding it with process and data insights, the Company also offers a wide range of technology services. Driven by a passion for process innovation and operational excellence built on its Lean and Six Sigma DNA and the legacy of serving GE for more than 14 years, its 55,000+ professionals around the globe deliver services to more than 600 clients from a network of 57 delivery centers across 16 countries supporting more than 30 languages. (b) Organization The Company has a unique heritage. The Company built its business by meeting the demands of the leaders of GE, to increase the productivity of their businesses. The Company began in 1997 as the India-based captive business process services operation for General Electric Capital Corporation, or GE Capital, GE's financial services business. As the Company demonstrated its value to GE management, the Company's business grew in size and scope. The Company took on a wide range of complex and critical processes and became a significant provider to many of GE's businesses, including Consumer Finance, Commercial Finance, Healthcare, Industrial, NBC Universal and GE's corporate offices. The Company started actively pursuing business from clients other than GE, which are referred to as Global Clients, from January 1, 2005. Since that time, it has succeeded in increasing the business and diversifying its revenue sources. 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 common shares. On March 24, 2010, the Company completed a secondary offering of its common shares by certain of its shareholders that was priced at $15 per share. The offering consisted of 38,640,000 common shares, which included the underwriters exercise of their option to purchase an additional 5,040,000 common shares from the Company's shareholders at the offering price of $15 per share to cover over-allotments. All of the common shares were sold by shareholders of the Company and, as a result, the Company did not receive any of the proceeds from the offering. The Company incurred expenses in connection with the secondary offering of approximately $591, included under 'Other income (expense), net' in the Consolidated Statement of Income for the year ended December 31, 2010. Upon the completion of the secondary offering, the General Electric Company's ("GE") shareholding in the Company decreased to 9.1% and it ceased to be a significant shareholder, although it continues to be a related party in accordance with the provisions of Regulation S-X Rule 1-02(s). Its shareholding has subsequently declined further to less than 5.0% as of December 31, 2011.

Summary Of Significant Accounting Policies [Abstract]

Summary Of Significant Accounting Policies

2. Summary of significant accounting policies

(a) Basis of preparation and principles of consolidation

The accompanying consolidated financial statements have been prepared in conformity with U.S. generally accepted accounting principles (U.S. GAAP).

The accompanying 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, and variable interest entities in which the Company is the primary beneficiary. When the Company does not have a controlling interest in an entity, but exerts a significant influence on the entity, the Company applies the equity method of accounting. All inter-company transactions and balances are eliminated in consolidation.

The noncontrolling interest disclosed in the accompanying consolidated financial statements represents the noncontrolling partners' interest in the operation of Genpact Netherlands B.V. and noncontrolling shareholders' interest in the operation of Hello Communications (Shanghai) Co., Ltd. and the profits or losses associated with the noncontrolling interest in those operations. The noncontrolling partners of Genpact Netherlands B.V. are individually liable for the tax obligations on their share 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 Consolidated Statements of Income.

On January 1, 2009 the Company reclassified amounts previously attributable to noncontrolling interest to a separate component of equity on the accompanying consolidated balance sheets and consolidated statements of equity and comprehensive income (loss). Additionally, net income attributable to noncontrolling interest is shown separately from net income in the consolidated statements of income. This reclassification had no effect on our previously reported financial position or results of operations.

(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, the reserve for doubtful receivables and the valuation allowance for deferred tax assets, the valuation of derivative financial instruments, the measurements of stock-based compensation, assets and obligations related to employee benefits, 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 consolidated financial statements.

c) Revenue recognition

The Company derives its revenue primarily from business process and technology management services, which are provided on both time-and-materials and fixed-price basis. The Company recognizes revenue from services under time-and-materials contracts when persuasive evidence of an arrangement exists; the sales price is fixed or determinable; and collectibility is reasonably assured. Such revenues are recognized as the services are provided. The Company's fixed-price contracts include contracts for application development, maintenance and support services. Revenues on these contracts are recognized ratably over the term of the agreement. The Company accrues for revenue and receivables for the services rendered between the last billing date and the balance sheet date.

Customer contracts can also include incentive payments received for discreet benefits delivered to clients. Revenues relating to such incentive payments are recorded when the contingency is satisfied and the Company concludes the amounts are earned.

Revenue with respect to fixed-price contracts for development of software is recognized on a percentage of completion method. Guidance has been drawn from FASB guidance on Software—Revenue Recognition to account for revenue from fixed price arrangements for software development and related services in conformity with FASB guidance on Revenue Recognition—Construction—Type and Production-Type Contracts. The input (effort expended) method has been used to measure progress towards completion as there is a direct relationship between input and productivity. Provisions for estimated losses, if any, on uncompleted contracts are recorded in the period in which such losses become probable based on the current contract estimates.

The Company has deferred the revenue and the costs attributable to certain process transition activities with respect to its customers where such activities do not represent the culmination of a separate earnings process. Such revenue and costs are subsequently recognized ratably over the period in which the related services are performed. Further, the deferred costs are limited to the amount of the deferred revenues.

Revenues are reported net of value-added tax, business tax and applicable discounts and allowances. Reimbursements of out-of-pocket expenses received from customers have been included as part of revenues.

The Company enters into multiple element revenue arrangements in which a customer may purchase a combination of its services. Revenue from multiple element arrangement is recognized based on (1) whether and when each element has been delivered; (2) fair value of each element is determined using the selling price hierarchy of vendor-specific objective evidence ("VSOE") of fair value, third-party evidence or using best estimated selling price, as applicable, and (3) allocation of the total price among the various elements based on the relative selling price method.

d) Accounts receivable

Accounts receivable are recorded at the invoiced / to be invoiced amount and do not bear interest. Amounts collected on trade accounts receivable are included in net cash provided by operating activities in the Consolidated Statements of Cash Flows. The Company maintains an allowance for doubtful accounts for estimated losses inherent in its accounts receivable portfolio. In establishing the required allowance, management considers historical losses adjusted to take into account current market conditions and our customers' financial condition, the amount of receivables in dispute, and the current receivables aging and current payment patterns. Account balances are charged off against the allowance after all means of collection have been exhausted and the potential for recovery is considered remote. The Company does not have any off-balance-sheet credit exposure related to its customers.

(e) Cash and cash equivalents

Cash and cash equivalents consist of cash balances and all highly liquid investments purchased with an original maturity of three months or less.

(f) Short term investments

All liquid investments with an original maturity greater than 90 days but less than one year are considered to be short term investments. Marketable short term investments are classified and accounted for as available-for-sale investments. Available-for-sale investments are reported at fair value with changes in unrealized gains and losses recorded as a separate component of accumulated other comprehensive income (loss) until realized. Realized gains and losses on investments are determined based on the specific identification method and are included in "Other income (expense), net". The Company does not hold these investments for speculative or trading purposes.

(g) Property, plant and equipment, net

Property, plant and equipment are stated at cost less accumulated depreciation and amortization. Expenditures for replacements and improvements are capitalized whereas the cost of maintenance and repairs are charged to earnings as incurred. The Company depreciates and amortizes all property, plant and equipment using the straight-line method over the following estimated economic useful lives of the assets:


		Years
Buildings		40
Furniture and fixtures		4
Computer equipment and servers		4
Plant, machinery and equipment		4
Computer software		4
Leasehold improvements		Lesser of lease period or 10 years
Vehicles		3-4

The Company capitalizes certain computer software and software development costs incurred in connection with developing or obtaining computer software for internal use when both the preliminary project stage is completed and it is probable that the software will be used as intended. Capitalized software costs include only (i) external direct costs of materials and services utilized in developing or obtaining computer software, (ii) compensation and related benefits for employees who are directly associated with the software project, and (iii) interest costs incurred while developing internal-use computer software. Capitalized software costs are included in property, plant and equipment on the Company's balance sheet and amortized on a straight-line basis when placed into service over the estimated useful lives of the software.

Advances paid towards acquisition of property, plant and equipment outstanding as of each balance sheet date and the cost of property, plant and equipment not put to use before such date are disclosed under "Capital work in progress".

(h) Research and development expense

Development costs incurred for software to be sold, if any, will be expensed as incurred as research and development costs until technological feasibility has been established for the product. Technological feasibility is established upon completion of a detailed design program or, in its absence, completion of a working model. Thereafter, all software production costs will be capitalized and amortized over their useful lives and reported at the lower of unamortized cost and net realizable value.

(i) Business combinations, goodwill and other intangible assets

The Company accounts for its business combinations by recognizing the identifiable tangible and intangible assets 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 acquisition date. A liability resulting from contingent consideration is remeasured to fair value at 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.

Goodwill represents the cost of the 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. Recoverability of goodwill is evaluated using a two-step process. The first step involves a comparison of the fair value of a reporting unit with its carrying value. If the carrying value of the reporting unit exceeds its fair value, the second step of the process involves a comparison of the fair value and carrying value of the goodwill of that reporting unit. If the carrying value of the goodwill of a reporting unit exceeds the fair value of that goodwill, an impairment loss is recognized in an amount equal to the excess. Goodwill of a reporting unit will be tested for 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 11 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		2-14 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 on the acquisition date.

(j) Impairment of long-lived assets

Long-lived assets, including certain intangible assets, to be held and used are reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount of such assets may not be recoverable. Such assets are required to be tested for impairment if the carrying amount of the assets is higher than the future undiscounted net cash flows expected to be generated from the assets. The impairment amount to be recognized is measured as the amount by which the carrying value of the assets exceeds its fair value. The Company determines fair value by using a discounted cash flow approach.

(k) Foreign currency

The consolidated financial statements are reported in U.S. Dollars. The functional currency of the Company is U.S. Dollars. The functional currency for subsidiaries organized in Europe, other than the U.K., is the Euro, and the functional currencies of subsidiaries organized in Brazil, China, Columbia, Guatemala, India, Japan, Morocco, South Africa, the Philippines, the U.K. and United Arab Emirates are their respective local currencies. The functional currency of all other legal entities forming part of the Company is the U.S. Dollar. The translation of the functional currencies of the respective subsidiaries into U.S. Dollars is performed for balance sheet accounts using the exchange rates in effect as of the balance sheet date and for revenues and expense accounts using a monthly average exchange rate prevailing during the respective period. The gains or losses resulting from such translation are reported under accumulated other comprehensive income (loss), net, as a separate component of equity.

Monetary assets and liabilities of each subsidiary denominated in currencies other than the subsidiary's functional currency are translated into their respective functional currency at the rates of exchange prevailing at the balance sheet date. Transactions of each subsidiary in currencies other than the subsidiary's functional currency are translated into the respective functional currency at the average monthly exchange rate prevailing during the period of the transaction. The gains or losses resulting from foreign currency transactions are included in the consolidated statements of income.

(l) Loans held for sale

In August 2006, the Company acquired MoneyLine Lending Services, Inc. (now known as Genpact Mortgage Services). Prior to May 31, 2007, one of its activities was to fund mortgage loans, which it then held for sale. Such loans held for sale are carried at the lower of cost or market value, which is determined on an individual loan basis. Market value is equal to the amount of unpaid principal, reduced by market valuation adjustments and increased or reduced by net deferred loan origination fees and costs.

(m) Derivative instruments and hedging activities

In the normal course of business, the Company uses derivative financial instruments to manage foreign currency exchange rate and interest rate risk. The Company purchases forward foreign exchange contracts to mitigate the risk of changes in foreign exchange rates on inter-company transactions and forecasted transactions denominated in foreign currencies.

The Company recognizes derivative instruments and hedging activities as either assets or liabilities in its consolidated balance sheets and measures them at fair value. Gains and losses resulting from changes in fair value are accounted for depending on the use of the derivative and whether it is designated and qualifies for hedge accounting. Changes in fair values of derivatives designated as cash flow hedges are deferred and recorded as a component of accumulated other comprehensive income (loss), net of taxes until the hedged transactions occur and are then recognized in the consolidated statements of income along with the underlying hedged item and disclosed as part of "Total net revenues", "Cost of revenue" and "Selling, general and administrative expenses", as applicable. Changes in fair value of derivatives not designated as hedging instruments and the ineffective portion of derivatives designated as cash flow, and interest rate hedges are recognized in the consolidated statements of income and are included in foreign exchange (gains) losses, net, and other income (expense), net, respectively.

With respect to derivatives designated as hedges, the Company formally documents all relationships between hedging instruments and hedged items, as well as its risk management objectives and strategy for undertaking various hedge transactions. The Company also formally assesses both at the inception of the hedge and on a quarterly basis, whether each derivative is highly effective in offsetting changes in fair values or cash flows of the hedged item. If it is determined that a derivative or a portion thereof is not highly effective as a hedge, or if a derivative ceases to be a highly effective hedge, the Company will prospectively discontinue hedge accounting with respect to that derivative.

In all situations in which hedge accounting is discontinued and the derivative is retained, the Company continues to carry the derivative at its fair value on the balance sheet and recognizes any subsequent change in its fair value in the consolidated statements of income. When it is probable that a forecasted transaction will not occur, the Company discontinues hedge accounting and recognizes immediately in foreign exchange (gains) losses, net in the consolidated statements of income, the gains and losses attributable to such derivative that were accumulated in other comprehensive income (loss).

(n) Income taxes

The Company accounts for income taxes using the asset and liability method of accounting for income taxes. Under this method, income tax expense is recognized for the amount of taxes payable or refundable for the current year. In addition, deferred tax assets and liabilities are recognized for future tax consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their tax bases and all operating loss carryforwards, if any. Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled. The effect on deferred tax assets and liabilities of a change in tax rates or tax status is recognized in the statement of income in the period that includes the enactment date or the filing/ approval date of the tax status change. Deferred tax assets are reduced by a valuation allowance if, based on the weight of available evidence, it is more likely than not that some portion or all of the deferred tax assets will not be realized.

The Company applies a two-step approach for recognizing and measuring uncertain tax positions. The first step is to evaluate the tax position for recognition by determining, based on the technical merits, that the position will be more likely than not sustained upon examination. The second step is to measure the tax benefit as the largest amount of the tax benefit that is greater than 50% likely of being realized upon settlement. The Company includes interest and penalties related to unrecognized tax benefits within its provision for income tax expense.

(o) Retirement benefits

Contributions to defined contribution plans are charged to consolidated statements of income in the period in which services are rendered by the covered employees. Current service costs for defined benefit plans are accrued in the period to which they relate. The liability in respect of defined benefit plans is calculated annually by the Company using the projected unit credit method. Prior service cost, if any, resulting from an amendment to a plan is recognized and amortized over the remaining period of service of the covered employees. The Company recognizes its liabilities for compensated absences dependent on whether the obligation is attributable to employee services already rendered, relates to rights that vest or accumulate and payment is probable and estimable.

The Company records annual amounts relating to its defined benefit plans based on calculations that incorporate various actuarial and other assumptions, including discount rates, mortality, assumed rates of return, compensation increases and turnover rates. The Company reviews its assumptions on an annual basis and makes modifications to the assumptions based on current rates and trends when it is appropriate to do so. The effect of modifications to those assumptions is recorded in accumulated other comprehensive income and amortized to net periodic cost over future periods using the corridor method. The Company believes that the assumptions utilized in recording its obligations under its plans are reasonable based on its experience and market conditions.

(p) Stock-based compensation

The Company recognizes and measures compensation expense for all stock-based awards based on the grant date fair value. For option awards, grant date fair value is determined under the option-pricing model (Black-Scholes-Merton) and for awards other than option awards, grant date fair value is determined on the basis of fair market value of a Company's share on the date of grant of such awards. The Company recognizes compensation expense for stock based awards net of estimated forfeitures. Stock-based compensation recognized in the consolidated statements of income for the years ended December 31, 2009, 2010 and 2011 is based on awards ultimately expected to vest. As a result the expense has been reduced for estimated forfeitures. Forfeitures are estimated at the time of grant and revised, if necessary, in subsequent periods if actual forfeitures differ from those estimates.

(q) 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 investments, 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 evaluation of the credit worthiness of the corporations and banks with which it does business. Short term deposits are with GE, a related party, and short term investments are with other financial institutions. To reduce its credit risk on accounts receivable, the Company performs an ongoing credit evaluation of customers. GE accounted for 43% and 36% of receivables as of December 31, 2010 and 2011, respectively. GE accounted for 40%, 38% and 30% of revenues for the years ended December 31, 2009, 2010 and 2011, respectively.

(r) Earnings (loss) per share

Basic earnings per share is computed using the weighted average number of common shares outstanding during the period. Diluted earnings per share is computed using the weighted average number of common and dilutive common equivalent shares outstanding during the period. For the purposes of calculating diluted earnings per share, the treasury stock method is used for stock based awards except where the results would be anti-dilutive.

(s) Commitments and contingencies

Liabilities for loss contingencies arising from claims, assessments, litigation, fines and penalties and other sources are recorded when it is probable that a liability has been incurred and the amount of the assessment and/or remediation can be reasonably estimated. Legal costs incurred in connection with the same are expensed as incurred.

(t) 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 standard has been adopted by the Company and certain disclosures in the consolidated financial statements and footnotes to the consolidated financial statements have been modified. Adoption of this standard did not impact the consolidated financial results as they are disclosure-only in nature:

•

In December 2010, FASB issued ASU 2010-29 which states that a public entity is required to disclose pro forma information for material business combinations (on an individual or aggregate basis) that occurred in the current reporting period. The disclosures include pro forma revenue and earnings of the combined entity for the current reporting period as though the acquisition date for all business combinations that occurred during the year had been as of the beginning of the annual reporting period. If comparative financial statements are presented, the pro forma revenue and earnings of the combined entity for the comparable prior reporting period should be reported as though the acquisition date for all business combinations that occurred during the current year had been as of the beginning of the comparable prior annual reporting period. The amendments in this update are effective prospectively for business combinations for which the acquisition date is on or after the beginning of the first annual reporting period beginning on or after December 15, 2010. Effective January 1, 2011, the Company adopted ASU 2010-29.

The following recently released accounting standards have been adopted by the Company without material impact on the Company's consolidated results of operations, cash flows, financial position or disclosures:

•

In December 2010, FASB issued ASU 2010-28 which states that for an entity with reporting units having zero or negative carrying amounts, the second step of the impairment test shall be performed to measure the amount of impairment loss, if any, when it is more likely than not that a goodwill impairment exists. In considering whether it is more likely than not that a goodwill impairment exists, an entity shall evaluate whether there are adverse qualitative factors. The amendments in this update are effective for fiscal years, and interim periods within those years, beginning after December 15, 2010. Effective January 1, 2011, the Company has adopted ASU 2010-28.

•

In April 2010, FASB issued ASU 2010-13 which states that an employee share-based payment award with an exercise price denominated in the currency of a market in which a substantial portion of the entity's equity securities trades should not be considered to contain a condition that is not a market, performance, or service condition. Therefore, such an award should not be classified as a liability based only on this condition if it otherwise qualifies as equity. The amendments in this update are effective for fiscal years, and interim periods within those fiscal years, beginning on or after December 15, 2010. Effective January 1, 2011, the Company has adopted ASU 2010-13.

(u) Reclassification

Certain reclassifications have been made in the consolidated financial statements of prior periods to conform to the classification used in the current period.

(a)	Included in prepaid expenses and other current assets, and other assets in the consolidated balance sheets.

(b)	Included in accrued expenses and other current liabilities, and other liabilities in the consolidated balance sheets.

(c)	Included in either cash and cash equivalents or short term investment, depending on the maturity profile, in the consolidated balance sheets.

Following is the reconciliation of loans held for sale which have been measured at fair value using significant unobservable inputs:


	As of December 31,
	2010			2011
Opening balance, net	$	552		$	530
Impact of fair value included in earnings		(12	)		(52	)
Settlements		(10	)		(9	)

Closing balance, net	$	530		$	469

The Company values the derivative instruments based on market observable inputs including both forward and spot prices for currencies. The quotes are taken from multiple independent sources including financial institutions. Loans held for sale are valued using collateral values based on inputs from a single source when the Company is not able to corroborate the inputs and assumptions with other relevant market information. Investments in U.S. Treasury bills which are classified as available-for-sale and cash and cash equivalents, depending on the maturity profile, are measured using quoted market prices at the reporting date multiplied by the quantity held.

- Definition

Tabular disclosure of the fair value measurement of assets and liabilities which includes [financial] instruments measured at fair value that are classified in stockholders' equity. Such assets and liabilities may be measured on a recurring or nonrecurring basis. The disclosures which may be required or desired include: (1) for assets and liabilities measured on a recurring basis, disclosure may include: (a) the fair value measurements at the reporting date; (b) the level within the fair value hierarchy in which the fair value measurements in their entirety fall, segregating fair value measurements using quoted prices in active markets for identical assets or liabilities (Level 1), significant other observable inputs (Level 2), and significant unobservable inputs (Level 3); (c) for fair value measurements using significant unobservable inputs (Level 3), a reconciliation of the beginning and ending balances, separately presenting changes during the period attributable to the following: (i) total gains or losses for the period (realized and unrealized), segregating those gains or losses included in earnings (or changes in net assets), and a description of where those gains or losses included in earnings (or changes in net assets) are reported in the statement of income (or activities); (ii) purchases, sales, issuances, and settlements (net); (iii) transfers in and transfers out of Level 3 (for example, transfers due to changes in the observability of significant inputs); (d) the amount of the total gains or losses for the period in subparagraph (c) (i) above included in earnings (or changes in net assets) that are attributable to the change in unrealized gains or losses relating to those assets and liabilities still held at the reporting date and a description of where those unrealized gains or losses are reported in the statement of income (or activities); (e) the valuation technique(s) used to measure fair value and a discussion of changes in valuation techniques, if any, during the period and (2) for assets and liabilities that are measured at fair value on a nonrecurring basis (for example, impaired assets) disclosure may include, in addition to (a) above: (a) the reasons for the fair value measurements recorded; (b) the same as (b) above; (c) for fair value measurements using significant unobservable inputs (Level 3), a description of the inputs and the information used to develop the inputs; and (d) the valuation technique(s) used to measure fair value and a discussion of changes, if any, in the valuation technique(s) used to measure similar assets and/or liabilities in prior periods. Where the quoted price in an active market for the identical liability is not available, the Level 1 input is the quoted price of an identical liability when traded as an asset.

Derivative Financial Instruments [Abstract]

Derivative Financial Instruments

8. Derivative financial instruments

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 / financial institutions and the Company considers the risks of non-performance by the counterparties as not material. The forward foreign exchange contracts mature between zero and sixty months and the forecasted transactions are expected to occur during the same period.

The following table presents the aggregate notional principal amounts of the 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,				As of December 31,
	2010		2011		2010			2011
Foreign exchange forward contracts denominated in:

					$	(26,337	)	$	(212,751	)

(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 instruments 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 also has derivative instruments that are not accounted for as hedges under the FASB guidance, to hedge the foreign exchange risks related to balance sheet items such as receivables and inter-company borrowings denominated in currencies other than the underlying functional currency.

The fair value of the derivative instruments and their location in the financial statements of the Company is summarized in the table below:


	Cash flow				Non-designated
	As of December 31, 2010		As of December 31, 2011		As of December 31, 2010		As of December 31, 2011
Assets

Other liabilities	$	19,728	$	154,724	$	—	$	—

Cash flow hedges

For derivative instruments that are designated and qualify as a cash flow hedge, the effective portion of the gain (loss) on the derivative instrument is reported as a component of accumulated 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 Company has recorded as a component of accumulated other comprehensive income (loss) or OCI within equity a gain (loss) of ($18,235), and $(131,881), net of taxes, as of December 31, 2010 and 2011, respectively.

The gains / losses recognized in accumulated other comprehensive income (loss), and their effect on financial performance is summarized below:

(a)

These forward foreign exchange contracts were entered into to hedge the fluctuations in foreign exchange rates for recognized balance sheet items such as receivables and inter-company borrowings, and were not originally designated as hedges under FASB guidance on Derivatives and Hedging. Realized (gains) losses and changes in the fair value of these derivatives are recorded in foreign exchange (gains) losses, net in the consolidated statements of income.

(b)

These forward foreign exchange contracts were initially designated as cash flow hedges under FASB guidance on Derivatives and Hedging. The net (gains) losses amounts of $11,746, $(234) and $0 for the years ended December 31, 2009, 2010 and 2011 respectively, include the recognition of losses for certain derivative contracts accounted for within accumulated other comprehensive income (loss). These losses were recognized as certain forecasted transactions are no longer expected to occur and therefore hedge accounting is no longer applied. For the years ended December 31, 2009, 2010 and 2011, losses of $13,964, $0 and $0, respectively, were recognized in the consolidated statements of income related to these non-designated contracts. In addition, these amounts also include subsequent realized (gains) losses and changes in the fair value of these derivatives and are recorded in foreign exchange (gains) losses, net in the consolidated statements of income.

The following table presents the changes in goodwill for the years ended December 31, 2010 and 2011:


	As of December 31,
	2010		2011

Opening balance	$	548,723	$	570,153

Goodwill has been allocated to the following reporting units as follows:

	$	570,153	$	925,339

During the fourth quarter of 2010, the Company changed its annual goodwill impairment testing date from September 30 to December 31 of each year. This change was made to improve alignment of impairment testing procedures with year-end financial reporting and the annual business planning and budgeting process, which concludes substantially during the fourth quarter of each year. As a result, the goodwill impairment testing will reflect the result of inputs from business in the development of the budget including the impact of seasonality of the company's financial results, which would provide improved visibility for the budgeting process. Accordingly, management considered this accounting change preferable. This change did not accelerate, delay, avoid, or cause an impairment charge, nor did this change result in adjustments to previously issued financial statements.

During 2010 and 2011, the Company performed its annual impairment review of goodwill and concluded that there was no impairment in either year. The results of our evaluation showed that the fair values of all reporting units exceeded their respective carrying values. The total amount of goodwill deductible for tax purposes is $10,474 and $7,562 as of December 31, 2010 and 2011, respectively.

The Company's intangible assets acquired either individually or with a group of other assets or in a business combination are as follows:


	As of December 31, 2010						As of December 31, 2011
	Gross carrying amount		Accumulated amortization		Net		Gross carrying amount		Accumulated amortization		Net

Amortization expenses for intangible assets as disclosed in the consolidated statements of income under amortization of acquired intangible assets for the years ended December 31, 2009, 2010 and 2011 were $25,969, $15,959 and $19,974, respectively. Intangible assets recorded for the 2004 reorganization, when we began operating as an independent company, include the incremental value of the minimum volume commitment from GE, entered into contemporaneously with the 2004 reorganization, over the value of the pre-existing customer relationship with GE. The amortization of this intangible asset for the years ended December 31, 2009, 2010 and 2011 was $571, $316 and $158, respectively, and has been reported as a reduction of revenue. As of December 31, 2011, the unamortized value of the intangible asset was $81, which will be amortized in future periods and reported as a reduction of revenue.

The estimated amortization schedule for the intangible assets for future periods is set out below:


For the year ending December 31
2012		20,989
2013		18,185
2014		16,004

Employee Benefit Plans [Abstract]

Employee Benefit Plans

19. Employee benefit plans

The Company has employee benefit plans in the form of certain statutory and other schemes covering its employees.

Defined benefit plans

In accordance with Indian law, the Company provides a defined benefit retirement plan (the "Gratuity Plan") covering substantially all of its Indian employees. The Gratuity Plan provides a lump sum payment to vested employees upon retirement or termination of employment in an amount based on each employee's salary and duration of employment with the Company. The Gratuity Plan benefit cost for the year is calculated on an actuarial basis.

In addition, in accordance with Mexican law, the Company provides termination benefits (the "Mexican Plan") to all of its Mexican employees for reasons other than restructuring to which employees are entitled based on age, years of service and salary of the employee. The Mexican Plan benefit cost for the year is calculated on an actuarial basis.

In addition, some of the company's subsidiaries in Philippines (the "Philippines Plan") and Japan (the "Japan Plan") have sponsored defined benefit retirement programs. The Japan Plan and Philippines Plan benefit cost for the year is calculated on an actuarial basis.

Current service costs for the defined benefit plan are accrued in the year to which they relate on a monthly basis. Actuarial gains or losses or prior service costs, if any, resulting from amendments to the plans are recognized and amortized over the remaining period of service of the employees.

The following table sets forth the funded status of the defined benefit plans and the amounts recognized in the Company's financial statements based on an actuarial valuation carried out as of December 31, 2010 and 2011.

The amount in accumulated other comprehensive income (loss) that is expected to be recognized as a component of net periodic benefit cost over the next fiscal year is $824.

The weighted average assumptions used to determine the benefit obligations of the Gratuity Plan as of December 31, 2010 and 2011 are presented below:


	As of December 31,
	2010			2011

Discount rate		8.65	%	9.3%-9.70%
Rate of increase in compensation per annum		8.00	%	8.00%-8.10%

The weighted average assumptions used to determine the benefit obligations of the Mexican Plan as of December 31, 2010 and 2011 are presented below:


	As of December 31,
	2010			2011

Discount rate		8.00	%		7.50	%

The weighted average assumptions used to determine the benefit obligation of the Japan Plan as of December 31, 2011 is presented below:


	As of December 31, 2011

Discount rate		0.90	%
Rate of increase in compensation per annum		0.00	%

The weighted average assumptions used to determine the Japan Plan costs for the years ended December 31, 2011 is presented below:


	As of December 31, 2011
Discount rate		0.90	%
Rate of increase in compensation per annum		0.00	%

Expected long term rate of return on plan assets per annum		0.00	%

The weighted average assumptions used to determine the benefit obligation of the Philippines Plan as of December 31, 2011 is presented below:


	As of December 31, 2011

Discount rate		6.29	%
Rate of increase in compensation per annum		4.00	%

The weighted average assumptions used to determine the Philippines Plan costs for the years ended December 31, 2011 is presented below:


	As of December 31, 2011

Discount rate		6.29	%
Rate of increase in compensation per annum		4.00	%
Expected long term rate of return on plan assets per annum		5.00	%

The above expected return on plan assets is based on Company's expectation of the average long term rate of return expected to prevail over the next 15 to 20 years on the types of investments prescribed as per the statutory pattern of investment.

The Company assesses these assumptions with its projected long-term plans of growth and prevalent industry standards. Unrecognized actuarial loss is amortized over the average remaining service period of the active employees expected to receive benefits under the plan.

The Company contributes the required funding for all ascertained liabilities to the Genpact India Employees' Gratuity Fund. Trustees administer contributions made to the trust, and contributions are invested in specific designated instruments as permitted by Indian law. The Company's overall investment strategy is to invest predominantly in fixed income funds managed by asset management companies. These funds further invest in debt securities like money market instruments, government securities and public and private bonds. During the years ending December 31, 2009, 2010 and 2011, all of the plan assets were primarily invested in debt securities.

Certain subsidiaries of the Company in Philippines and Japan sponsor a defined benefit plan. Such plans are funded and the Company contributions are made to insurer managed funds or to a trust. The contributions to the trust are further invested in Government bonds.

The fair values of Company's plan assets as of December 31, 2010 and 2011 by asset category are as follows:

Stock-Based Compensation

12 Months Ended

Dec. 31, 2011

Stock-Based Compensation [Abstract]

Stock-Based Compensation

20. Stock-based compensation

The Company has issued options under the Genpact Global Holdings 2005 Plan (the "2005 Plan"), Genpact Global Holdings 2006 Plan (the "2006 Plan"), Genpact Global Holdings 2007 Plan (the "2007 Plan") and 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 up to 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 15, 2011.

A brief summary of each plan is provided below:

2005 Plan

Under the 2005 Plan, which was adopted on July 26, 2005, the Company is authorized to issue up to 12,210,750 options to eligible persons and has granted 12,403,445 options up to the year ended December 31, 2011.

2006 Plan

Under the 2006 Plan, which was adopted on February 27, 2006, the Company is authorized to issue up to 4,942,369 options to eligible persons and has granted 5,260,692 options up to the year ended December 31, 2011.

2007 Plan

Under the 2007 Plan, which was adopted on March 27, 2007, the Company is authorized to issue up to 16,733,250 options to eligible persons and has granted 8,647,050 options up to the year ended December 31, 2011.

2007 Omnibus Plan

The Company adopted the 2007 Omnibus Plan on July 13, 2007 and it was amended and restated on April 15, 2011. The 2007 Omnibus Plan provides for the grant of options intended to qualify as incentive stock options, non-qualified stock options, share appreciation rights, restricted share awards, restricted share units, performance units, cash incentive awards and other equity-based or equity-related awards. Under the 2007 Omnibus Plan the Company is authorized to grant awards for the issuance of common shares in the future up to a limit of 9,406,800 common shares to eligible persons, of which 8,499,033 options, 2,903,648 Restricted Share Units and 2,792,196 Performance Units were granted up to the year ended December 31, 2011.

The stock-based compensation costs relating to above plans during the years ended December 31, 2009, 2010 and 2011, were $19,262, $17,446 and $27,677 respectively, have been allocated to cost of revenue and selling, general, and administrative expenses.

The tax benefit recognized in relation to stock based compensation charge during the years ended December 31, 2009, 2010 and 2011 was $4,617, $3,872 and $7,800, respectively. No realized tax benefit on the options exercised during the years ended December 31, 2009, 2010 and 2011 has been recorded through shareholders' equity due to losses in U.S. subsidiaries.

The options granted are subject to the requirement of vesting. Options granted under the plan 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. For options granted after January 1, 2006, the Company recognizes compensation cost over the vesting period of the option. Compensation cost is determined at the date of grant by estimating the fair value of an option using the Black-Scholes option-pricing model.

The following table shows the significant assumptions used in connection with the determination of the fair value of options in 2009, 2010 and 2011:


	2009	2010	2011
Dividend yield	-	-		—
Expected life (in months)	76 - 78	75		75
Risk free rate of interest	2.07% - 3.39%	2.02% - 3.16%		2.26	%
Volatility	37.7% - 46.44%	36.47% - 37.36%		37.32	%

Volatility was calculated based on the historical volatility of our comparative companies during a period equivalent to the estimated term of the option. The Company estimates the expected term of an option using the "simplified method" which is based on the average of the vesting term and contractual term of the option. The risk-free interest rate that we use in the option valuation model is based on U.S. Treasury bonds with a term similar to the expected term of the options. Expected dividends during the estimated term of the option are based on recent dividend activity; the Company has not paid any cash dividends in the recent period and do not anticipate doing so in the foreseeable future.

The Company has issued, and intends to continue to issue, new shares to satisfy stock option exercises under its incentive plans.

A summary of the options granted during the years ended December 31, 2009, 2010 and 2011 is set out below:

As of December 31, 2011, the total remaining unrecognized stock-based compensation costs related to RSUs amounted to $23,385 which will be recognized over the weighted average remaining requisite vesting period of 3.17 years.

Performance Units

The Company also makes stock awards in the form of Performance Units or PUs under the 2007 Omnibus Plan.

During the years ended December 31, 2010 and 2011, the Company granted PUs, wherein each PU represents the right to receive a common share based on the Company's performance against specified targets. These PUs 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 term 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 that will be issued will be 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 expense will be based on a comparison of the final performance metrics to the specified targets.

A summary of PUs activity during the year ended December 31, 2010 and 2011 is set out below:

As of December 31, 2011, the total remaining unrecognized stock based compensation costs related to PUs amounted to $19,043 which will be recognized over the weighted average remaining requisite vesting period of 1.73 years.

In the first quarter of 2011, the compensation committee of the board of directors of the Company modified the performance metrics for the performance grants made to employees in March 2010 from Revenue and EBITDA growth to Revenue and adjusted operating income growth


	Original Performance Target						Modified Performance Target
Performance Level	Revenue Growth			EBITDA Growth			Revenue Growth			Adjusted Income from Operation growth
Outstanding		20.0	%		20.0	%		20.0	%		20.0	%
Target		15.0	%		15.0	%		15.0	%		15.0	%
Threshold		10.0	%		10.0	%		10.0	%		10.0	%

For the August 2010 performance unit grant to the former CEO, who changed his role to Non-Executive Vice-Chairman as of June 17, 2011, in addition to the modification made to the performance metrics from revenue and EBITDA growth to revenue and adjusted operating income growth, because the award vests based on annual performance targets whereas the awards to the employees vest based on average performance over three years, revision has been made to the performance targets in order to make the performance targets consistent with performance unit grants made to employees in the first quarter of 2011.


	Original Performance Target						Modified Performance Target
Performance Level	Revenue Growth			EBITDA Growth			Revenue Growth			Adjusted Income from Operation growth
Outstanding		20.0	%		20.0	%		17.0	%		16.0	%
Target		15.0	%		15.0	%		12.5	%		12.5	%
Threshold		10.0	%		10.0	%		8.0	%		7.0	%

As a result of the above mentioned modifications, 45 employees were affected and incremental compensation cost of $4,109 is to be recognized over a period of 21.5 months starting from March 2011 to December 31, 2012. Out of the total incremental compensation cost, $2,878 and $ 1,231 is to be recognized over the years 2011 and 2012 respectively.

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 allowed eligible employees to purchase the Company's common shares through payroll deduction at 95% of the fair value per share on the last business day of each purchase interval ending on or prior to August 31, 2009. The purchase price has been reduced to 90% of the fair value per share on the last business day of each purchase interval commencing with effect from September 1, 2009. The dollar amount of common shares purchased under the ESPP shall 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 year ended December 31, 2009, 2010 and 2011, common shares issued under ESPP was 41,476, 44,581 and 49,192, respectively.

The ESPP was considered as non compensatory under the FASB guidance on Compensation-Stock Compensation until the purchase interval ending on or prior to August 31, 2009. As a result of the change in the discount rate, the ESPP is being considered compensatory with effect from September 1, 2009.

The compensation expenses for the employee stock purchase plan is recognized in accordance with the FASB guidance on Compensation-Stock Compensation. The compensation expense for ESPP during the years ended December 31, 2009, 2010 and 2011 was $23, $68 and $90, respectively, and has been allocated to cost of revenue and selling, general, and administrative expenses.

Capital Stock	12 Months Ended
Capital Stock	Dec. 31, 2011
Capital Stock [Abstract]
Capital Stock	21. Capital stock The Company's authorized capital stock as of December 31, 2010 and 2011 consisted of 500 million common shares with a par value of $0.01 per share, and 250 million preferred shares with a par value of $0.01 per share. Of the above, the Company had 220,916,960 and 222,347,968 common shares, and no preferred shares, issued and outstanding as of December 31, 2010 and 2011, respectively. The holders of common shares are entitled to one vote per share. Upon the liquidation, dissolution or winding up of the Company, common shareholders are entitled to receive a ratable share of the available net assets of the Company after payment of all debts and other liabilities. The common shares have no preemptive, subscription, redemption or conversion rights. The Company's board of directors by resolution can establish one or more series of preferred shares having such par value, designations, dividend rates, relative voting rights, conversion or exchange rights, redemption rights, liquidation rights and other relative participation, optional or other rights, qualifications, limitations or restrictions as may be fixed by the board of directors without any shareholder approval. Such rights, preferences, powers and limitations as may be established could also have the effect of discouraging an attempt to obtain control of the Company. These preferred shares are of the type commonly known as "blank-check" preferred shares. Under Bermuda law, the Company may declare and pay dividends from time to time unless there are reasonable grounds for believing that the Company is or would, after the payment, be unable to pay its liabilities as they become due or that the realizable value of its assets would thereby be less than the aggregate of its liabilities, its issued share capital, and its share premium accounts. Under the Company's bye-laws, each common share is entitled to dividends if, as and when dividends are declared by the Company's board of directors. There are no restrictions in Bermuda on the Company's ability to transfer funds (other than funds denominated in Bermuda dollars) in or out of Bermuda or to pay dividends to U.S. residents who are holders of our common shares. The Company's ability to declare and pay cash dividends is restricted by its debt covenants.

Earnings Per Share [Abstract]

Earnings Per Share

22. Earnings per share

The Company calculates earnings per share in accordance with FASB guidance on Earnings per Share. Basic and diluted earnings per common share give effect to the change in the number of common shares of the Company. The calculation of 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, common shares to be issued under employee stock purchase plan and performance units 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 options outstanding but not included in the computation of diluted earnings per common share because their effect was anti-dilutive is 12,480,950, 9,189,505 and 6,995,632 for the years ended December 31, 2009, 2010 and 2011, respectively.

A portion of the profits of the Company's operations is exempt from income tax in India. The tax holiday under the STPI Scheme was available for a period of ten consecutive years beginning in the year in which the respective Indian undertaking commenced operations and expired completely as at March 31, 2011. One of the Company's Indian subsidiaries has four units eligible for tax holiday as a Special Economic Zone unit in respect of 100% of the export profits for a period of 5 years, 50% of such profits for next 5 years and 50% of the profits for further period of 5 years subject to satisfaction of certain capital investments requirements. One of these unit commenced operations in 2007, two in 2008 and one in 2009.

The basic earnings per share effect of the tax holiday is $0.12, $0.14 and $0.10, respectively, for the years ended December 31, 2009, 2010 and 2011. The diluted earnings per share effect of the tax holiday is $0.12, $0.14 and $0.10, respectively, for the years ended December 31, 2009, 2010 and 2011.

As a result of the change in tax status of one of its subsidiaries in the U.S. during the year ended December 31, 2007, the Company recognized the tax effects in the consolidated statement of income for the adjustment in deferred tax liability associated with the unrealized gains on certain effective hedges in other comprehensive income. During the year ended December 31, 2009, 2010 and 2011, the Company recognized a reversal of deferred tax liability amounting to $10,343, $658 and $0 for the hedges that matured in 2009, 2010 and 2011.

The components of the deferred tax balances as of December 31, 2010 and 2011 are as follows:

Closing valuation allowance	$	7,943		$	4,605		$	11,542

In assessing the realizability of deferred tax assets, management considers whether it is more likely than not that some or all of the deferred tax assets will not be realized. The ultimate realization of deferred tax assets depends on the generation of future taxable income during the periods in which those temporary differences are deductible. Management considers the scheduled reversal of deferred tax liabilities, projected taxable income, and tax planning strategies in making this assessment. In order to fully realize the deferred tax asset, the Company will need to generate future taxable income prior to the expiration of the deferred tax asset governed by the tax code. Based on the level of historical taxable income and projections for future taxable income over the periods for which the deferred tax assets are deductible, management believes that it is more likely than not that the Company will realize the benefits of these deductible differences, net of the existing valuation allowances at December 31, 2011. The amount of the deferred tax asset considered realizable, however, could be reduced in the near term if estimates of future taxable income during the carry-forward period are reduced.

As of December 31, 2011, the deferred tax assets related to operating loss carryforwards amounted to $63,059. Operating losses of subsidiaries in Hungary, the UK, Hong Kong, Australia, Singapore, Malaysia and Brazil amounting to $52,512 can be carried forward for an indefinite period. The remaining tax loss carry forwards expire as per the below table:

Of the total U.S.—Federal net operating loss carry forwards of approximately $198,500, $17,627 relates to excess tax deductions resulting from share-based compensation as of December 31, 2011.

As of December 31, 2011, the Company had additional deferred tax assets on U.S. state and local tax loss carryforwards amounting to $8,700 with varying expiration periods that begin to expire in 2015 through 2031.

Undistributed earnings of the Company's foreign subsidiaries amounted to approximately $589,717 as of December 31, 2011. The Company plans to indefinitely reinvest these undistributed earnings of foreign

subsidiaries, except for those earnings for which a deferred tax liability was accrued, or has the ability to repatriate in a tax-free manner. Accordingly, with limited exceptions, the Company does not accrue any income, distribution or withholding taxes that would arise if such earnings were repatriated.

As of December 31, 2011, $327 million of the $408 million of cash and cash equivalents were held by our foreign subsidiaries and branch offices. We intend to either permanently reinvest $312 million of the cash held by our foreign subsidiaries or repatriate in a tax-free manner. We have accrued U.S. taxes on the remaining cash of $15 million held by one of our foreign subsidiary and the same can be repatriated to the U.S. without accruing any additional U.S. tax expense.

The following table summarizes the activities related to our unrecognized tax benefits for uncertain tax positions from January 1, to December 31, for 2009, 2010 and 2011:


	Year ended December 31,
	2009			2010			2011
Opening balance at January 1	$	10,993		$	13,195		$	20,016
Increase related to prior year tax positions, including recorded against goodwill		3,043			4,735			2,997
Decrease related to prior year tax positions		(2,736	)		(788	)		(175	)
Increase related to current year tax positions, including recorded against goodwill		1,618			2,609			2,765
Effect of exchange rate changes		277			265			(1,891	)

Closing balance at December 31	$	13,195		$	20,016		$	23,712

As of December 31, 2009, 2010 and 2011, the Company had unrecognized tax benefits amounting to $13,019, $19,860 and $23,551, respectively, which if recognized, would impact the effective tax rate.

As of December 31, 2009, 2010 and 2011, the Company has accrued approximately $1,930, $2,020 and $2,536, respectively, in interest relating to unrecognized tax benefits. During the years ended December 31, 2009, 2010 and 2011, the Company recognized approximately $279, $90 and $516, respectively, in interest expense. No penalties were accrued as of December 31, 2009, 2010 and 2011, as the Company believes that the tax positions taken have met the minimum statutory requirements to avoid payment of penalties.

In the next twelve months and for all the tax years that remain open to examinations by U.S. federal and various state, local, and non-U.S. tax authorities, the Company estimates that it is reasonably possible that the total amount of its unrecognized tax benefits will vary. The Company does not expect significant changes within the next twelve months other than depending on the progress of tax matters or examinations with various tax authorities, which are difficult to predict.

With exceptions, the Company is no longer subject to U.S. federal, state and local or non-U.S. income tax audits by taxing authorities for years prior to 2007. The Company's subsidiaries in India and China are open to examination by the relevant taxing authorities for tax years beginning on April 1, 2008, and January 1, 2000, respectively. The Company regularly reviews the likelihood of additional tax assessments and adjusts its reserves as additional information or events require.

- Definition

The entire disclosure for income taxes. Disclosures may include net deferred tax liability or asset recognized in an enterprise's statement of financial position, net change during the year in the total valuation allowance, approximate tax effect of each type of temporary difference and carryforward that gives rise to a significant portion of deferred tax liabilities and deferred tax assets, utilization of a tax carryback, and tax uncertainties information.

Segment Reporting [Abstract]

Segment Reporting

28. Segment reporting

The Company manages various types of business process and information technology services in an integrated manner to clients in various industries and geographic locations. The Company's operations are located in sixteen countries. The Company's Chief Executive Officer, who has been identified as the Chief Operation Decision Maker (CODM), reviews financial information prepared on a consolidated basis, accompanied by disaggregated information about revenue and adjusted operating income by identified business units. The identified business units are organized for operational reasons and represent either services-based, customer-based, industry-based or geography-based units. There is a significant overlap between the manner in which the business units are organized. Additionally, the composition and organization of the business units is fluid and the structure changes regularly in response to the growth of the overall business acquisitions and changes in reporting structure, clients, services, industries served, and Delivery Centers.

Based on an overall evaluation of all facts and circumstances and after combining operating segments with similar economic characteristics that comply with other aggregation criteria specified in the FASB guidance on Segment Reporting, the Company has determined that it operates as a single reportable segment.

- Definition

Includes currency on hand as well as demand deposits with banks or financial institutions. It also includes other kinds of accounts that have the general characteristics of demand deposits in that the Entity may deposit additional funds at any time and also effectively may withdraw funds at any time without prior notice or penalty. Cash equivalents, excluding items classified as marketable securities, include short-term, highly liquid investments that are both readily convertible to known amounts of cash, and so near their maturity that they present minimal risk of changes in value because of changes in interest rates. Generally, only investments with original maturities of three months or less qualify under that definition. Original maturity means original maturity to the entity holding the investment. For example, both a three-month US Treasury bill and a three-year Treasury note purchased three months from maturity qualify as cash equivalents. However, a Treasury note purchased three years ago does not become a cash equivalent when its remaining maturity is three months. Compensating balance arrangements that do not legally restrict the withdrawal or usage of cash amounts may be reported as Cash and Cash Equivalents, while legally restricted deposits held as compensating balances against borrowing arrangements, contracts entered into with others, or company statements of intention with regard to particular deposits are not generally reported as cash and cash equivalents. Includes cash and cash equivalents associated with the entity's continuing operations. Excludes cash and cash equivalents associated with the disposal group (and discontinued operation).

- Definition

Investments in debt and equity securities which are categorized neither as trading securities nor held-to-maturity securities and which are intended be sold or mature within one year from the balance sheet date or the normal operating cycle, whichever is longer. Such securities are reported at fair value; unrealized gains (losses) related to Available-for-sale Securities are excluded from earnings and reported in a separate component of shareholders' equity (other comprehensive income), unless the Available-for-sale security is designated as a hedge or is determined to have had an other than temporary decline in fair value below its amortized cost basis. All or a portion of the unrealized holding gain (loss) of an Available-for-sale security that is designated as being hedged in a fair value hedge is recognized in earnings during the period of the hedge, as are other than temporary declines in fair value below the cost basis for investments in equity securities and debt securities that an entity intends to sell or it is more likely than not that it will be required to sell before the recovery of its amortized cost basis. Other than temporary declines in fair value below the cost basis for debt securities categorized as Available-for-sale that an entity does not intend to sell and for which it is not more likely than not that the entity will be required to sell before the recovery of its amortized cost basis are bifurcated into credit losses and losses related to all other factors. Other than temporary declines in fair value below cost basis related to credit losses are recognized in earnings, and losses related to all other factors are recognized in other comprehensive income.
