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 (“US GAAP”). The accompanying financial statements have been prepared on a consolidated basis and reflect the financial statements of ExlService Holdings and all of its subsidiaries. All intercompany balances and transactions have been eliminated in consolidation.

The non-controlling interest at December 31, 2012 represented the minority partner’s interest in the operations of exl Service.com (India) Private Limited (“Exl India”) and the profits associated with the minority partner’s interest in those operations, in the consolidated balance sheets and consolidated statements of income, respectively. During the year ended December 31, 2013, the Company purchased the entire non-controlling interest from the minority partner for an insignificant amount. The minority partner’s interest in the operations for the years ended December 31, 2013, 2012 and 2011 was insignificant and is included under general and administrative expenses in the consolidated statements of income.

(b) Use of Estimates

The preparation of the consolidated financial statements in conformity with US GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the consolidated financial statements and the consolidated statements of income during the reporting period. Although these estimates are based on management’s best assessment of the current business environment, actual results may be different from those estimates. The significant estimates and assumptions that affect the financial statements include, but are not limited to, allowance for doubtful receivables, service tax receivables, assets and obligations related to employee benefit plans, deferred tax valuation allowances, income-tax uncertainties and other contingencies, valuation of derivative financial instruments, stock-based compensation expense, depreciation and amortization periods, purchase price allocation, recoverability of long-term assets including goodwill and intangibles, and estimates to complete the fixed price contracts.

(c) Foreign Currency Translation

The functional currency of each entity in the Company is its respective local country currency which is also the currency of the primary economic environment in which it operates except for the entities in Mauritius which use the U.S. dollar as it’s functional currency. Monetary assets and liabilities in foreign currencies are re-measured into functional currency at the rates of exchange prevailing at the balance sheet dates. Transactions in foreign currencies are re-measured into functional currency at the rates of exchange prevailing on the date of the transaction. All transaction foreign exchange gains and losses are recorded in the accompanying consolidated statements of income.

The assets and liabilities of the subsidiaries for which the functional currency is other than the U.S. dollar are translated into U.S. dollars, the reporting currency, at the rate of exchange prevailing on the balance sheet dates. Revenues and expenses are translated into U.S. dollars at the exchange rates prevailing on the last business day of each month, which approximates the average monthly exchange rate. Resulting translation adjustments are included in accumulated other comprehensive loss in the audited consolidated balance sheets.

(d) Revenue Recognition

The Company derives its revenues from outsourcing and transformation services. Revenues from outsourcing services are recognized primarily on a time-and-material, cost-plus or unit-priced basis; revenues from transformation services are recognized primarily on a time-and-material and fixed price basis. The services provided within our outsourcing and transformation contracts generally contain one unit of accounting except the information technology contracts involving complex implementation services and post contract maintenance services. Revenues are recognized under our contracts generally when persuasive evidence of an arrangement exists, the sales price is fixed or determinable, services have been performed and collection of amounts billed is reasonably assured.

Revenues under time-and-material contracts are recognized as the services are performed. Revenues are recognized on cost-plus contracts on the basis of contractually agreed direct and indirect costs incurred on a client contract plus an agreed upon profit mark-up. Such revenues are recognized as the related services are provided in accordance with the client contract. When the terms of the client contract specify service level parameters that must be met (such as turnaround time or accuracy), we monitor such service level parameters to determine if any service credits or penalties have been incurred. Revenues are recognized net of any service credits that are due to a client. We have experienced minimal service credits and penalties to date. Revenue on contingent fee based contracts is recognized when the related contingency has been met to the client’s satisfaction.

Revenues for Company’s fixed-price transformation services contracts are recognized using the proportional performance method when the pattern of performance under the contracts can be reasonably determined. We estimate the proportional performance of a contract by comparing the actual number of hours or days worked to the estimated total number of hours or days required to complete each engagement. The use of the proportional performance method requires significant judgment relative to estimating the number of hours or days required to complete the contracted scope of work, including assumptions and estimates relative to the length of time to complete the project and the nature and complexity of the work to be performed. We regularly monitor our estimates for completion of a project and record changes in the period in which a change in an estimate is determined. If a change in an estimate results in a projected loss on a project, such loss is recognized in the period in which it is first identified.

Revenues from software licensing arrangements, which does not involve significant production, modification, or customization of software, are recognized at the later of time of delivery or expiration of significant termination rights as long as other revenue recognition criteria (mentioned above) are met. When there are significant production, modifications or customization, installation, systems integration or related services, the professional services and license revenues are combined as a single unit of account and maintenance services, if any, as a separate unit of account and the total contract fees are allocated among the two based on residual value method. Revenues related to license fee and the complex information technology application development services are recognized as the service is performed using the percentage of completion method of accounting, under which the total value of revenue is recognized on the basis of the percentage that each contract’s total labor hours to date bears to the total expected labor hours (input method). Revenues related to the maintenance services contract, whether entered into solely for providing such services or is segregated from a multiple element contract, is recognized on a straight-line basis over the contract term unless revenues are earned and obligations are fulfilled in a different pattern.

The Company accrues for revenue and receivables for services rendered between the last billing date and the balance sheet date. Accordingly, our accounts receivable include amounts for services that we have performed and for which an invoice has not yet been issued to the client.

Reimbursements of out-of-pocket expenses received from clients have been included as part of revenues on a gross basis. Revenues for the following periods include reimbursements of out-of-pocket expenses:


Year ended December 31, 2013	$	18,621
Year ended December 31, 2012	$	18,862
Year ended December 31, 2011	$	16,073

(e) Cash and Cash Equivalents and Restricted Cash

The Company considers all highly liquid investments purchased with an original maturity of ninety days or less to be cash equivalents. Pursuant to the Company’s investment policy, its surplus funds are kept as cash or cash equivalents and are invested in highly-rated mutual funds, money market accounts and time deposits to reduce its exposure to market risk with regard to these funds.

Current restricted cash represents amounts on deposit with banks against bank guarantees issued through banks for equipment imports that will mature on various dates before December 31, 2014, as well as client funds held in dedicated bank accounts.

Non-current restricted cash represents amounts on deposit with banks against bank guarantees issued through banks for equipment imports and for demands against pending income tax assessments (see Note 15 for details), that will mature on various dates after December 31, 2014.

(f) Investments

The Company’s investments consist of time deposits with financial institutions which are valued at cost and approximate fair value. Interest earned on such investments is included in interest income. Investments with original maturities greater than ninety days but less than twelve months are classified as short-term investments. Investments with maturities greater than twelve months from the balance sheet date are classified as long-term investments.

(g) Accounts Receivable

Accounts receivable are recorded net of allowances for doubtful accounts. Allowances for doubtful accounts are established through the evaluation of the accounts receivable aging and prior collection experience to estimate the ultimate collectability of these receivables. As of December 31, 2013 and 2012, the Company had $91 and $207 of allowance for doubtful accounts, respectively.

Accounts receivable include unbilled accounts receivable which represents revenues for services performed but yet to be billed to the client. As of December 31, 2013 and 2012, the Company had $16,400 and $15,601 of unbilled accounts receivable, respectively.

(h) Fixed Assets

Fixed assets are stated at cost less accumulated depreciation. Equipment held under capital leases are stated at the lower of present value of minimum lease payments at the inception of the leases or its fair value. Advances paid towards acquisition of fixed assets and the cost of fixed assets not yet placed in service before the end of the period are classified as construction in progress.

Fixed assets are reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount may not be recoverable through an assessment of the estimated future undiscounted cash flows related to such assets. In the event that assets are found to be carried at amounts that are in excess of estimated undiscounted future cash flows, the carrying value of the related asset or group of assets is reduced to a level commensurate with fair value based on a discounted cash flow analysis.

Depreciation is computed using the straight-line method over the estimated useful lives of the assets. Depreciation and amortization on equipment held under capital leases and leasehold improvements are computed using the straight-line method over the shorter of the assets’ estimated useful lives or the lease term.

The estimated lives used in determining depreciation are as follows:


	Estimated Useful Life (Years)
Network equipment, computers and software		3-5
Buildings		30
Leasehold improvements		3-8
Office furniture and equipment		3-7
Motor vehicles		2-5

(i) Business Combinations, Goodwill and Other Intangible Assets

ASC topic 805, “Business Combinations” (ASC No. 805), requires that the purchase method of accounting be used for all business combinations. The guidance specifies criteria as to intangible assets acquired in a business combination that must be recognized and reported separately from goodwill. Under ASC topic 350, “Intangibles—Goodwill and Other” (ASC No. 350), 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, relying on a number of factors including operating results, business plans and estimated future cash flows of the reporting units to which it is assigned. 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. The fair value of the reporting unit is measured by discounting estimated future cash flows. If the carrying amount 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 is tested for impairment annually or 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.

Intangible assets acquired in a business combination are initially valued and recognized at fair market value using generally accepted valuation methods appropriate for the type of intangible asset. Intangible assets with definite lives are amortized over the estimated useful lives and are reviewed for impairment, if indicators of impairment arise. The evaluation of impairment is based upon a comparison of the carrying amount of the intangible asset to its fair value, which is calculated using the estimated future undiscounted net cash flows expected to be generated by the asset. If the fair value of the intangible assets is less than the carrying amount of the asset, the asset is considered impaired and an impairment expense is recognized equal to any shortfall in the current period.

The Company’s definite lived intangible assets are amortized over their estimated useful lives as listed below using a straight-line method:


Customer relationships			3-15 years
Leasehold benefits			3-8 years
Developed technology			5-10 years
Non-compete agreements			1-2 years
Trade names and trademarks			3-5 years

(j) Derivative Financial Instruments.

In the normal course of business, the Company uses derivative instruments for the purpose of mitigating the exposure from foreign currency fluctuation risks associated with forecasted transactions denominated in certain foreign currencies and to minimize earnings and cash flow volatility associated with changes in foreign currency exchange rates, and not for speculative trading purposes. These derivative contracts are purchased within the Company’s policy and are with counterparties that are highly rated financial institutions.

The Company hedges anticipated transactions that are subject to foreign exchange exposure with foreign currency exchange contracts that qualify as cash flow hedges. Changes in the fair value of these cash flow hedges which are deemed effective, are recorded in accumulated other comprehensive income/(loss) (AOCI) until the hedged transactions occur and at that time are recognized in the consolidated statements of income. Changes in the fair value of cash flow hedges deemed ineffective are recognized in the consolidated statement of income and are included in foreign exchange (loss)/gain. The Company also uses derivatives instruments consisting of foreign currency exchange contracts to hedge intercompany balances and other monetary assets or liabilities denominated in currencies other than the functional currency. Changes in the fair value of these derivatives are recognized in the consolidated statements of income and are included in foreign exchange (loss)/gain.

The Company evaluates hedge effectiveness at the time a contract is entered into as well as on an ongoing basis. If during this time, a contract is deemed ineffective, the change in the fair value is recorded in the consolidated statements of income and is included in foreign exchange (loss)/gain. For hedge relationships that are discontinued because the forecasted transaction is not expected to occur by the end of the originally specified period, any related derivative amounts recorded in equity are reclassified to earnings.

(k) Retirement Benefits

Contributions to defined contribution plans are charged to the 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.

(l) Share-Based Compensation

The Company recognizes stock-based compensation expense in the consolidated financial statements for awards of equity instruments to employees and non-employee directors based on the grant-date fair value of those awards. The Company recognizes these compensation costs, net of an estimated forfeiture rate, over the requisite service period of the award. Forfeitures are estimated at the time of grant and revised, if necessary, in subsequent periods if actual forfeiture differ from those estimates.

(m) Income Taxes

The Company calculates and provides for income taxes in each of the tax jurisdictions in which it operates. The deferred tax assets and liabilities are recognized for future tax consequences attributable to temporary differences between the financial statement carrying values of existing assets and liabilities and their respective tax bases and all operating losses carried forward, if any. Deferred tax assets and liabilities are measured using tax rates expected to apply to taxable income in the years in which the applicable 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 in which the change is identified. Deferred tax assets are reduced by a valuation allowance if, based on available evidence, it is more likely than not that some portion or all of the deferred tax assets will not be realized.

The Company establishes provisions for uncertain tax provisions and related interest and penalties when the Company believes those tax positions are not more likely than not of being sustained, if challenged.

(n) Financial Instruments and Concentration of Credit Risk

Financial Instruments. For certain financial instruments including cash and cash equivalents, short-term investments, accounts receivable, accounts payable, accrued expenses, and other current liabilities, recorded amounts approximate fair value due to the relatively short maturity periods of such instruments.

Concentration of Credit Risk . Financial instruments that potentially subject the Company to concentrations of credit risk consist principally of cash and cash equivalents, time deposits, accounts receivable and derivative financial instruments. By their nature, all such financial instruments involve risks including the credit risks of non-performance by counterparties. Pursuant to the Company’s investment policy, its surplus funds are maintained as cash or cash equivalents and are invested in highly-rated mutual funds, money market accounts and time deposits, placed with highly rated financial institutions to reduce its exposure to market risk with regard to these funds. Credit losses on accounts receivable have not been material because of a large concentration of revenues with a small number of large, established companies. The Company evaluates the creditworthiness of its clients in conjunction with its revenue recognition processes as well as through its ongoing collectability assessment processes for accounts receivable.

(o) Earnings Per Share

Basic earnings per share is computed by dividing net income to common stockholders by the weighted average number of common shares outstanding during each period. Diluted earnings per share is computed using the weighted average number of common shares plus the potentially dilutive effect of common stock equivalents issued and outstanding at the reporting date, using the treasury stock method. Stock options, restricted stock and restricted stock units that are anti-dilutive are excluded from the computation of weighted average shares outstanding.

The following table sets forth the computation of basic and diluted earnings per share:


	Year ended December 31,
	2013		2012		2011
Numerators:
Net income	$	48,097	$	41,836	$	34,780
Denominators:
Basic weighted average common shares outstanding		32,750,178		31,968,386		30,264,805

Diluted	$	1.42	$	1.26	$	1.10
Weighted average common shares considered anti-dilutive in computing diluted earnings per share		268,219		413,493		424,081

(p) Accumulated Other Comprehensive Loss

For the Company, comprehensive loss consists of net earnings/(loss), amortization of actuarial gain/(loss) on retirement benefits and changes in the cumulative foreign currency translation adjustments. In addition, the Company enters into foreign currency exchange contracts, which are designated as cash flow hedges in accordance with ASC No. 815. Changes in the fair values of contracts that are deemed effective are recorded as a component of accumulated other comprehensive loss until the settlement of that contract. The balances as of December 31, 2013 and 2012 are as follows:


	December 31,			December 31,
	2013			2012
Cumulative currency translation adjustments	$	(50,091	)	$	(30,486	)
Unrealized loss on cash flow hedges, net of taxes of ($2,736) and ($2,521)		(9,699	)		(5,456	)
Retirement benefits, net of taxes of ($263) and ($203)		(928	)		(705	)

Accumulated other comprehensive loss	$	(60,718	)	$	(36,647	)

(s) Recent Accounting Pronouncements

In February 2013, the FASB issued ASU No. 2013-02, “Reporting of Amounts Reclassified out of Accumulated Other Comprehensive Income” (ASU No. 2013-02). Under ASU No. 2013-02, an entity is required to provide information about the amounts reclassified out of accumulated other comprehensive income (“AOCI”) by component. In addition, an entity is required to present, either on the face of the financial statements or in the notes, significant amounts reclassified out of AOCI by the respective line items of net income, but only if the amount reclassified is required to be reclassified in its entirety in the same reporting period. For amounts that are not required to be reclassified in their entirety to net income, an entity is required to cross-reference to other disclosures that provide additional details about those amounts. ASU No. 2013-02 does not change the current requirements for reporting net income or other comprehensive income in the financial statements. ASU No. 2013-02 became effective from January 1, 2013 and the new guidance did not have any material impact on the Company’s consolidated financial statements.

In March 2013, the FASB issued ASU No. 2013-05, “Parent’s Accounting for the Cumulative Translation Adjustment upon Derecognition of Certain subsidiaries or Groups of Assets within a Foreign Entity or of an Investment in a Foreign Entity” (ASU 2013-05). It applies to the release of the currency translation adjustment into net income when a parent either sells a part of all of its investment in a foreign entity or no longer holds a controlling financial interest in a subsidiary or group of assets that is a nonprofit activity or a business within a foreign entity. For public entities, the amendments are effective for fiscal years and interim reporting periods beginning after December 15, 2013. The Company is currently assessing the impact, if any, on its consolidated financial statements.

In July 2013, the FASB issued ASU No. 2013-11, “Presentation of an Unrecognized Tax Benefit When a Net Operating Loss Carryforward, a Similar Tax Loss, or a Tax Credit Carryforward Exists” (ASU No. 2013-11). The provisions of the rule require an unrecognized tax benefit to be presented as a reduction to a deferred tax asset in the financial statements for a net operating loss carryforward, a similar tax loss, or a tax credit carryforward except in circumstances when the carryforward or tax loss is not available at the reporting date under the tax laws of the applicable jurisdiction to settle any additional income taxes or the tax law does not require the entity to use, and the entity does not intend to use, the deferred tax asset for such purposes. When those circumstances exist, the unrecognized tax benefit should be presented in the financial statements as a liability and should not be combined with deferred tax assets. The new financial statement presentation provisions relating to this update are prospective and effective for interim and annual periods beginning after December 15, 2013, with early adoption permitted. The Company is currently assessing the impact, if any, on its consolidated financial statements.

These services are provided in an integrated manner to clients in various industries. The chief operating decision maker (“CODM”) generally reviews financial information at the consolidated statement of income level disaggregated by our two segments: Outsourcing Services and Transformation Services, but does not review any information except for revenues and cost of revenues of these individual segments. Therefore, the Company does not allocate or evaluate operating expenses, interest expense or income, capital expenditures, and income taxes to its operating segments. Consequently, it is not practical to show assets, capital expenditures, depreciation or amortization by segment.

Business Combinations [Abstract]

Business Combinations, Goodwill and Intangible Assets

5. Business Combinations, Goodwill and Intangible Assets

On October 12, 2012, the Company acquired Landacorp Inc., a leading provider of healthcare solutions and technology. Landacorp has more than 50 million lives under management on its software platforms and has developed services and technology solutions that share vital clinical data with payers, providers, plan participants and accountable care organizations. The Landacorp acquisition furthers the Company’s strategic intent to continue investing in the healthcare domain and strengthen its capabilities to serve the U.S. healthcare industry and continue to invest in building processes, analytics and platform capabilities in its focused verticals. Accordingly, the Company paid a premium for the acquisition which is being reflected in the goodwill recognized from the purchase price allocation of the total consideration paid by the Company.

The total purchase price of the acquisition is as follows:


Enterprise Value	$	37,500
Add: Working capital adjustments*		1,183

Total purchase price	$	38,683

paid in January 2013

After the December 31, 2012 consolidated financial statements were issued, the Company received further information including a revised valuation report from a third party valuation firm with respect to the Landacorp acquisition. After considering the results of the additional information, the Company revised its estimates related to certain of its acquired intangibles and other assets as of the date of acquisition as follows:


	Revised Allocation		Initial Allocation

Fair Value Disclosures [Abstract]

Fair Value Measurements

6. Fair Value Measurements

ASC 820, “Fair Value Measurements and Disclosures” (ASC 820) defines fair value as the price that would be received upon sale of an asset or paid upon transfer of a liability in an orderly transaction between market participants at the measurement date and in the principal or most advantageous market for that asset or liability. The fair value should be calculated based on assumptions that market participants would use in pricing the asset or liability, not on assumptions specific to the entity. In addition, the fair value of liabilities should include consideration of non-performance risk, including the Company’s own credit risk.

ASC 820 establishes a three-level hierarchy of fair value measurements based on whether the inputs to those measurements are observable or unobservable. Observable inputs reflect market data obtained from independent sources, while unobservable inputs reflect the Company’s market assumptions. The fair-value hierarchy requires the use of observable market data when available and consists of the following levels:

•

Level 1—Quoted prices for identical instruments in active markets;

•

Level 2—Quoted prices for similar instruments in active markets; quoted prices for identical or similar instruments in markets that are not active; and model-derived valuations in which all significant inputs are observable in active markets; and

•

Level 3—Valuations derived from valuation techniques in which one or more significant inputs are unobservable.

The following table sets forth the Company’s assets and liabilities that were accounted for at fair value as of December 31, 2013 and 2012. The table excludes short-term investments, accounts receivable, accounts payable and accrued expenses for which fair values approximate their carrying amounts.

Derivative Instruments And Hedging Activities Disclosure [Abstract]

Derivatives and Hedge Accounting

7. Derivatives and Hedge Accounting

The Company uses derivative instruments and hedging transactions to mitigate exposure to foreign currency fluctuation risks associated with forecasted transactions denominated in certain foreign currencies and to minimize earnings and cash flow volatility associated with changes in foreign currency exchanges rates. The Company’s derivative financial instruments are largely forward foreign exchange contracts that are designated effective and that qualify as cash flow hedges under ASC 815, “Derivatives and hedging” (ASC 815). The Company also uses derivatives consisting of foreign currency exchange contracts not designated as hedging instruments under ASC 815 to hedge intercompany balances and other monetary assets or liabilities denominated in currencies other than the Company’s functional currency (“fair value hedges”). The Company’s primary exchange rate exposure is with the Indian rupee, the Philippine peso and the U.K. pound sterling. The Company also has exposure in Czech koruna and other local currencies in which it operates.

The Company had outstanding foreign exchange contracts totaling $262,085 and GBP 10,973 as of December 31, 2013 and totaling $221,255 and GBP 11,544 as of December 31, 2012. The Company estimates that approximately $7,252 of net derivative losses included in accumulated other comprehensive loss (“AOCI”) could be reclassified into earnings within the next 12 months based on exchange rates prevailing as of December 31, 2013. At December 31, 2013, the maximum outstanding term of the cash flow hedges was forty-five months.

The Company evaluates hedge effectiveness at the time a contract is entered into as well as on an ongoing basis. If during this time, a contract is deemed ineffective, the change in the fair value is recorded in the consolidated statements of income and is included in foreign exchange (loss)/gain. For hedging positions that are discontinued because the forecasted transaction is not expected to occur by the end of the originally specified period, any related derivative amounts recorded in equity are reclassified to earnings. No such significant amounts of gains or losses were reclassified from AOCI into earnings during the year ended December 31, 2013 and 2012.

The following tables set forth the fair value of the foreign currency exchange contracts and their location on the consolidated financial statements:

Derivatives designated as hedging instruments:


	December 31,		December 31,
	2013		2012
Other current assets:
Foreign currency exchange contracts	$	437	$	980
Other assets:

Accrued expenses and other current liabilities:
Foreign currency exchange contracts	$	7,689	$	6,249
Other non current liabilities:
Foreign currency exchange contracts	$	5,606	$	3,458

Derivatives not designated as hedging instruments:

Employee Benefit Plans

10. Employee Benefit Plans

The Company’s Gratuity Plans in India and the Philippines provides a lump sum payment to vested employees on retirement or on termination of employment in an amount based on the respective employee’s salary and years of employment with the Company. Liabilities with regard to the Gratuity Plans are determined by actuarial valuation using the projected unit credit method. Current service costs for the Gratuity Plan are accrued in the year to which they relate. 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 benefit obligation has been measured as of December 31, 2013. The following table sets forth the activity and the funded status of the Gratuity Plan and the amounts recognized in the Company’s consolidated financial statements at the end of the relevant periods:

The Gratuity Plans in India are partially funded and are managed and administered by Life Insurance Corporation of India and HDFC Standard Life Insurance Company. They calculate the annual contribution required to be made by the Company and manage the Gratuity Plans, including any required payouts. Fund managers manage these funds on a cash accumulation basis and declare interest retrospectively on March 31 of each year. The Company earned a return on the Gratuity Plans of approximately 9.5% per annum for the year ended March 31, 2013.

The fiscal year under the Indian Income Tax Act ends on March 31. Certain of the Company’s operations centers in India qualified for an exemption from corporate tax under the Indian Income Tax Act which expired on April 1, 2011. Therefore, profits generated from the services provided from such operations centers have become fully taxable and consequently, the Company’s tax expense increased from 2011 and may continue to be higher going forward.

The Company benefited from a four-year income tax holiday for one of its operations centers in the Philippines that expired in May 2012. The tax benefit was extendable by two successive one-year periods on fulfillment of certain performance and investment criteria. The Company fulfilled such obligations and extensions were granted by the Philippines Economic Zone Authority (“PEZA”) in February 2013 retroactively from May 2012 and in May 2013 for an additional one year which will expire in May 2014. Other operations centers in the Philippines, which began operations in January 2012 and in May 2013, respectively, benefit from a separate four-year income tax holiday from the date of their starting operations that can be extended at PEZA’s discretion for two successive one-year periods. While the Company is reasonably certain that these benefits will continue to be available for the expected period, it is possible that such tax holidays or extensions may be conditioned or removed entirely due to changes in applicable legislation by the government of the Philippines. Should any of these events occur, the Company’s tax liability in the Philippines would likely increase.

The Company’s operations centers in Jaipur and Noida, India, which were established in Special Economic Zones (“SEZs”) in 2010, are eligible for tax incentives until 2020. As part of the OPI Acquisition, the Company also acquired operations centers in Bengaluru and Kochi, India that are also established in SEZs. The operations center in Bengaluru completed its first five years of operations on March 31, 2012 during which such operations were entitled to a 100% tax exemption on export profits. Under Indian tax regulations, the Bengaluru operations center is entitled to a 50% tax exemption on export profits for five years from April 1, 2012. The Company’s tax expense for the Bengaluru center increased after April 1, 2012 and will further increase after the expiration of the current five-year term in 2017. The Company also established a new operations center in Pune, India in June 2012 and in Kochi, India in May 2013, both of which are located in SEZs. The Company anticipates establishing additional operations centers in SEZs or other tax advantaged locations in the future.

The diluted earnings per share effect of the tax holiday is $0.16, $0.10 and $0.10 for the years ended December 31, 2013, 2012 and 2011, respectively.

The components of the deferred tax balances as of December 31, 2013 and 2012 are as follows:


	December 31,

Deferred tax assets:
Tax credit carry forward	$	3,332		$	2,932

Deferred tax liabilities:	$	13,170		$	13,487

Net deferred tax assets	$	19,212		$	21,583

Deferred tax assets and liabilities are recognized for future tax consequences attributable to temporary differences between the financial statement carrying values of assets and liabilities and their respective tax bases and operating loss carry forwards. At December 31, 2013 and 2012, the Company performed an analysis of the deferred tax asset valuation allowance for net operating loss carry forward for its domestic entities. Based on this analysis, the Company continues to carry a valuation allowance on the deferred tax assets on certain net operating loss carry forwards. Accordingly, the Company had recorded a valuation allowance of $665 each as of December 31, 2013 and 2012.

As a result of the OPI Acquisition and the Landacorp Acquisition, the Company acquired federal and state net operating losses in the United States. Thus, as of December 31, 2013, the Company has federal net operating loss carry forwards of approximately $26,934, which expire through various years till 2032. The Company’s federal net operating loss carry forwards are subject to certain annual utilization limitations under Section 382 of the United States Internal Revenue Code. The Company also has state and local net operating loss carry forwards of varying amounts, which are subject to limitations under the applicable rules and regulations of those taxing jurisdictions. The Company estimates that it will be able to utilize all of the losses before their expiration.

The Company’s Indian subsidiaries are liable to pay Minimum Alternative Tax (MAT) under India’s domestic tax laws. As of December 31, 2013 and 2012 deferred income taxes related to the MAT were $3,332 and $2,932, respectively expiring through various years until 2024.

At December 31, 2013 and 2012, no deferred income taxes have been provided for the Company’s share of undistributed net earnings of foreign operations due to management’s intent to reinvest such amounts indefinitely. The determination of the amount of such unrecognized deferred taxes is not practicable. Those earnings totaled approximately $185,596 and $153,906 as of December 31, 2013 and 2012, respectively.

The Company’s provision for income taxes also includes the impact of provisions established for uncertain income tax positions determined in accordance with ASC No. 740, “Income Taxes,” as well as the related net interest. Tax exposures can involve complex issues and may require an extended resolution period. Although the Company believes that it has adequately reserved for its uncertain tax positions, no assurance can be given that the final tax outcome of these matters will not be different. The Company adjusts these reserves in light of changing facts and circumstances, such as the closing of a tax audit or the refinement of an estimate. To the extent that the final tax outcome of these matters differs from the amounts recorded, such differences will impact the provision for income taxes in the period in which such determination is made.

The following table summarizes the activity related to the gross unrecognized tax benefits from January 1, 2013 through December 31, 2013:


Balance as of January 1, 2013	$	3,019
Increases related to prior year tax positions		1,759
Decreases related to prior year tax positions		—
Increases related to current year tax positions		357
Decreases related to current year tax positions		—
Effect of exchange rate changes		(222	)

Balance as of December 31, 2013	$	4,913

The unrecognized tax benefits as of December 31, 2013 of $4,913, if recognized, would impact the effective tax rate.

The Company has recognized interest and penalties of $283 during the year ended December 31, 2013, which is included in the income tax provision in the consolidated statements of income. The unrecognized tax benefits may increase or decrease in the next twelve months depending on the Company’s tax positions.

Stock Based Compensation

13. Stock Based Compensation

In 2006, the Company instituted the ExlService Holdings, Inc. 2006 Omnibus Award Plan (the 2006 Plan) which replaced the 2003 Plan. The 2006 Plan covers all of the employees of the Company. Under the 2006 Plan, the Compensation Committee (“the Committee”) may grant awards of nonqualified stock options, incentive stock options, stock appreciation rights, restricted stock, restricted stock units, stock bonus awards, performance based compensation awards (including cash bonus awards) or any combination of the foregoing.

The Committee determines which employees are eligible to receive the equity awards, the number of equity awards to be granted, the exercise price, the vesting period and the exercise period. The vesting period for the equity award issued is determined on the date of the grant and is non-transferable during the life of the equity award. The majority of options expire ten years from the date of grant and generally vest incrementally over a period of four years from the date of grant with 10% vesting at the end of year one, 20% vesting at the end of year two, 30% vesting at the end of year three and 40% vesting at the end of year four. Pursuant to the 2006 Plan, the Company reserved 3,399,384 shares of common stock (in addition to the available pool of 329,854 shares from the 2003 plan) for the granting of equity awards. If an employee resigns or is terminated, the employee must exercise any vested options within 90 days after termination or the vested options are forfeited. At a special meeting of the Company’s stockholders held on January 29, 2009, the Company’s stockholders approved, among other things, an amendment to the 2006 Plan to increase the number of shares of its common stock issuable there under by 4,000,000 shares, which brought the total number of shares reserved under the plan to 7,729,238.

The Company applies the provisions of ASC No. 718, “compensation-stock compensation” to account for it’s stock based compensation, using the modified prospective method of transition. Under the provisions of this guidance, the estimated fair value of share-based awards granted under stock incentive plans is recognized as compensation expense over the vesting period.

The following costs related to the Company’s stock-based compensation plan are included in the consolidated statements of income:


	Year ended December 31,
	2013		2012		2011
Cost of revenue	$	2,413	$	1,893	$	1,635
General and administrative expenses		5,077		4,551		4,589
Selling and marketing expenses		4,342		2,972		3,238

Total ⁽¹⁾	$	11,832	$	9,416	$	9,462

(1)	The Company, during the year ended December 31, 2013, recognized an additional stock compensation expense of $854 as a result of modified vesting conditions on certain restricted stock units.

The fair value of each stock option granted to employees is estimated on the date of grant using the Black-Scholes option-pricing model with the following weighted average assumptions:


	Year ended December 31,
	2013			2012			2011
Dividend yield		0	%		0	%		0	%
Expected life (years)		5.50			5.38			5.58
Risk free interest rate		0.87	%		0.97	%		2.16	%
Volatility		40	%		40	%		40	%

The estimated expected term of options granted has been based on historical experience, which is representative of the expected term of the options. Volatility has been calculated based on the volatility of the Company’s common stock and the volatility of stocks of comparative companies. The risk-free interest rate that the Company uses in the option valuation model is based on U.S. treasury zero-coupon bonds with a remaining term similar to the expected term of the options.

The Company does not anticipate paying any cash dividends in the foreseeable future and therefore uses an expected dividend yield of zero in the option valuation model. The Company is required to estimate forfeitures at the time of grant and revise those estimates in subsequent periods if actual forfeitures differ from those estimates. The Company uses historical data to estimate pre-vesting option forfeitures and records stock-based compensation expense only for those awards that are expected to vest. All stock-based payment awards are amortized on a straight-line basis over the requisite service periods of the awards, which are generally the vesting periods.

Stock option activity under the Company’s stock plans is shown below:

The unrecognized compensation cost for unvested options as of December 31, 2013 is $2,786, which is expected to be expensed over a weighted average period of 1.75 years. The weighted-average fair value of options granted during the years ended December 31, 2013, 2012 and 2011 was $10.07, $9.43 and $8.16, respectively. The total grant date fair value of options vested during the years ended December 31, 2013, 2012 and 2011 was $3,061, $3,000 and $3,099, respectively. The aggregate intrinsic value of options exercised during the years ended December 31, 2013, 2012 and 2011 was $8,960, $12,020 and $4,180, respectively.

Subsequent to December 31, 2013, the Company granted approximately 500,000 restricted stock units and 9,800 stock options to its employees and directors.

Restricted Stock and Restricted Stock Units

An award of restricted stock is a grant of shares subject to conditions and restrictions set by the Committee. The grant or the vesting of an award of restricted stock may be conditioned upon service to the Company or its affiliates or upon the attainment of performance goals or other factors, as determined in the discretion of the Committee. The Committee may also, in its discretion, provide for the lapse of restrictions imposed upon an award of restricted stock. Holders of an award of restricted stock may have, with respect to the restricted stock granted, all of the rights of a stockholder, including the right to vote and to receive dividends.

The Committee is authorized to award restricted stock units to participants. The Committee establishes the terms, conditions and restrictions applicable to each award of restricted stock units, including the time or times at which restricted stock units will be granted or vested and the number of units to be covered by each award. The terms and conditions of each restricted stock award will be reflected in a restricted stock unit agreement.

Any cash or in-kind dividends paid with respect to unvested shares of restricted stock and restricted stock units are withheld by the Company and paid to the holder of such shares of restricted stock, without interest, only if and when such shares of restricted stock and restricted stock units vest. Any unvested shares of restricted stock and restricted stock units are immediately forfeited without consideration upon the termination of holder’s employment with the Company or its affiliates. Accordingly, the Company’s unvested restricted stock and restricted stock units do not include non-forfeitable rights to dividends or dividend equivalents and are therefore not considered as participating securities for purposes of earnings per share calculations pursuant to the two-class method.

Restricted stock and restricted stock unit activity under the Company’s stock plans is shown below:

Commitments And Contingencies Disclosure [Abstract]
Commitments and Contingencies	15. Commitments and Contingencies *Fixed Asset Commitments* At December 31, 2013, the Company has committed to spend approximately $12,239 under agreements to purchase fixed assets. This amount is net of capital advances paid in respect of these purchases. *Other Commitments* Certain units of the Company’s Indian subsidiaries were established as 100% Export-Oriented units under the Software Technology Parks of India (“STPI”) scheme promulgated by the Government of India which provided the Company with certain incentives on imported and indigenous capital goods on fulfillment of certain conditions. Although the corporate tax incentives under the STPI scheme are no longer available to the Company, the units are required to fulfill such conditions for a limited time. In the event that these units are unable to meet the prescribed conditions over the specified period, the Company may be required to refund those incentives along with penalties and fines. The Company’s management believes, however, that these units have in the past satisfied and will continue to satisfy the required conditions. The Company’s operations centers in the Philippines are registered with PEZA. The registration provides the Company with certain fiscal incentives on the import of capital goods and requires Exl Philippines to meet certain performance and investment criteria. The Company’s management believes that these centers have in the past satisfied and will continue to satisfy the required criteria. *Contingencies* U.S. and Indian transfer pricing regulations require that any international transaction involving associated enterprises be at an arm’s-length price. Accordingly, the Company determines the appropriate pricing for the international transactions among its associated enterprises on the basis of a detailed functional and economic analysis involving benchmarking against transactions among entities that are not under common control. The tax authorities have jurisdiction to review this arrangement and in the event that they determine that the transfer price applied was not appropriate, the Company may incur increased tax liability, including accrued interest and penalties. The Company is currently involved in disputes with the Indian tax authorities over the application of some of its transfer pricing policies for some of its subsidiaries. Further, the Company and its U.S. subsidiary, ExlService.com LLC are engaged in tax litigation with the income-tax authorities in India on the issue of permanent establishment. The aggregate disputed amount demanded by Income tax authorities from the Company related to its transfer pricing issues for various years ranging from tax years 2003 to 2009 and its permanent establishment issues ranging from tax years 2003 to 2007 as of December 31, 2013 and 2012 is $14,742 and $18,624, respectively of which the Company has already made payment or provided bank guarantee to the extent $13,797 and $14,715, respectively. Amounts paid as deposits in respect of such assessments aggregating to $11,653 and $12,307 as of December 31, 2013 and 2012, respectively, are included in “Other assets” and amounts deposited for bank guarantees aggregating to $2,144 and $2,408 as of December 31, 2013 and 2012, respectively, are included in “Restricted cash” in the non-current assets section of the Company’s consolidated balance sheets as of December 31, 2013 and 2012. Based on advice from its Indian tax advisors, the facts underlying its position and its experience with these types of assessments, the Company believes that the probability of crystallization of these liabilities is remote and accordingly has not accrued any amount with respect to these matters in its consolidated financial statements. The Company does not expect any impact from these assessments on its future income tax expense. It is possible that the Company might receive similar orders for subsequent years. Even if these disputes are resolved, the Indian tax authorities may still serve additional orders.

Use of Estimates

(b) Use of Estimates

The preparation of the consolidated financial statements in conformity with US GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the consolidated financial statements and the consolidated statements of income during the reporting period. Although these estimates are based on management’s best assessment of the current business environment,actual results may be different from those estimates. The significant estimates and assumptions that affect the financial statements include, but are not limited to, allowance for doubtful receivables, service tax receivables, assets and obligations related to employee benefit plans, deferred tax valuation allowances, income-tax uncertainties and other contingencies, valuation of derivative financial instruments, stock-based compensation expense, depreciation and amortization periods, purchase price allocation, recoverability of long-term assets including goodwill and intangibles, and estimates to complete the fixed price contracts.

Accumulated change in equity from transactions and other events and circumstances from non-owner sources, net of tax effect, at period end. Excludes Net Income (Loss), and accumulated changes in equity from transactions resulting from investments by owners and distributions to owners. Includes foreign currency translation items, certain pension adjustments, unrealized gains and losses on certain investments in debt and equity securities, other than temporary impairment (OTTI) losses related to factors other than credit losses on available-for-sale and held-to-maturity debt securities that an entity does not intend to sell and it is not more likely than not that the entity will be required to sell before recovery of the amortized cost basis, as well as changes in the fair value of derivatives related to the effective portion of a designated cash flow hedge.
