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.

(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 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 its 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 Operations Management and Analytics and Business Transformation services. Revenues from Operations Management are recognized primarily on a time-and-material, cost-plus, transaction—based and outcome-based pricing; revenues from Analytics and Business Transformation services are recognized primarily on a time-and-material and fixed price basis. The services provided by the Company under its contracts with the customer generally contain one unit of accounting except the software and related services contracts involving implementation services and post contract maintenance services. In such multiple element arrangements, revenue is allocated to maintenance based the price charged when that element is sold separately (vendor specific objective evidence or “VSOE”). Revenues are recognized under our contracts generally when four basic criteria are met; 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, transaction-based and outcome-based 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. 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 Analytics and Business Transformation 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.

The Company’s software and related services contracts generally contain software license, related services and maintenance elements. Maintenance revenues are generally recognized on a straight-line basis over the contract term as they are separable and have VSOE. Services related to software licenses are evaluated to determine whether those services are significant or essential to the functionality of the software. When services are not considered essential, software license revenues and the related services are considered as one unit of accounting and recognized on a proportional performance basis or ratably as the services are performed. When services are significant or considered essential, revenues related to license fee and services are recognized as the services are 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).

The Company accrues revenue 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.

On November 1, 2013, the Company received a notice of termination from The Travelers Indemnity Company (“Travelers”) under the Professional Services Agreement, dated as of March 7, 2006, between the Company and Travelers (as amended from time to time, the “Services Agreement”), and is required to provide transition services for a period of up to eighteen months, including reimbursing Travelers for certain of their transition related expenses. The Company recognized $26,347 and $351 of such reimbursements as a reduction of revenues during the year ended December 31, 2014 and 2013, respectively in accordance with Accounting Standards Codification topic 605-50-45, “Revenue Recognition (“ASC No. 605”).”

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, 2014	$	19,606
Year ended December 31, 2013	$	18,621
Year ended December 31, 2012	$	18,862

(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, 2015, 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 16 for details), that will mature on various dates after December 31, 2015.

(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, 2014 and 2013, the Company had $120 and $91 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, 2014 and 2013, the Company had $16,735 and $16,400 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) Software Development Costs

Costs incurred for developing software or enhancements to the existing software products to be sold are capitalized, including the salaries and benefits of employees that are directly involved in the installation and development, once technological feasibility has been established upon completion of a detailed design program or, in its absence, completion of a working model. The capitalized costs are amortized on a straight-line basis over the estimated useful life. Costs associated with preliminary project stage activities, training, maintenance and all post-implementation stage activities are expensed as incurred.

(j) 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

(k) 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. The Company also uses derivatives instruments consisting of foreign currency exchange contracts to economically 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.

The Company evaluates hedge effectiveness of cash flow hedges 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. 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.

(l) Employee 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.

(m) 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.

On February 13, 2014, the Compensation Committee of the Board of Directors of the Company approved the program allowing for the grant of performance-based restricted stock units (“PRSUs”) to executive officers and other specified employees under its existing 2006 Omnibus Award Plan.

Under this program, 50% of the PRSUs will cliff vest at the end of a three-year period based on a revenue target for 2016 (“PUs”). However, up to one-third of the PUs may be earned based on the Company’s revenue performance in each of 2014 and 2015 against annual revenue targets in those years. The total amount of PUs that the recipient earns based on these performance criteria, will be the greater of (i) the PUs earned in 2016 and (ii) the sum of the earned PUs in 2014 and 2015. The other 50% shall be based on a market condition (“MUs”) that is contingent on meeting or exceeding the total shareholder return relative to a group of peer companies specified under the program, measured over a three-year performance period. The award recipient may earn up to two hundred percent (200%) of the PRSUs granted based on the actual performance for both kinds of PRSUs.

The fair value of each PU was determined based on the market price of one common share of the Company on the date of grant, and the associated compensation expense was calculated on the basis that performance targets to receive 100% of the PUs is probable of being achieved. The compensation expense for the PUs is recognized on a straight-line basis over the service period, which is through the end of 2016. Over this 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 an expense will be based on a comparison of the final performance metrics to the specified targets.

The grant date fair value for the MUs was determined using a Monte Carlo simulation model and the related compensation expense will be expensed on a straight-line basis over the vesting period. All compensation expense related to the MUs will be recognized if the requisite performance period is fulfilled, even if the market condition is not achieved.

(n) 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.

(o) 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.

(p) 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:

(q) Accumulated Other Comprehensive Loss

For the Company, comprehensive loss consists of net earnings, 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 those contracts. The balances as of December 31, 2014 and 2013 are as follows:


	December 31,			December 31,
	2014			2013
Cumulative currency translation adjustments	$	(55,553	)	$	(50,091	)

Recent Accounting Pronouncements

In March 2013, the Financial Accounting Standards Board (“the FASB”) issued Accounting Standards Update (“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”). ASU 2013-05 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. ASU 2013-05 became effective from January 1, 2014 and the new guidance did not have any material impact on the Company’s 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 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. ASU No. 2013-11 became effective from January 1, 2014 and the new guidance did not have any material impact on the Company’s consolidated financial statements.

In May 2014, the FASB issued ASU No. 2014-09, “Revenue from Contracts with Customers” (“ASU 2014-09”). The new standard is effective for reporting periods beginning after December 15, 2016 and early adoption is not permitted. The comprehensive new standard will supersede existing revenue recognition guidance and require revenue to be recognized when promised goods or services are transferred to customers in amounts that reflect the consideration to which the Company expects to be entitled in exchange for those goods or services. Adoption of the new rules could affect the timing of revenue recognition for certain transactions of the Company. ASU 2014-09 is effective for the Company in the first quarter of fiscal 2017 using either one of two methods: (i) retrospectively to each prior reporting period presented with the option to elect certain practical expedients as defined within ASU 2014-09; or (ii) retrospectively with the cumulative effect of initially applying ASU 2014-09 recognized at the date of initial application and providing certain additional disclosures as defined per ASU 2014-09. The Company is currently evaluating the impact of adoption and the implementation approach to be used.

In June 2014, the FASB issued ASU No. 2014-12, “Accounting for Share-Based Payments When the Terms of an Award Provide That a Performance Target Could Be Achieved after the Requisite Service Period” (“ASU 2014-12”). The amendments in ASU 2014-12 require that a performance target in a share based payment that affects vesting and that could be achieved after the requisite service period should be accounted for as a performance condition. The amendments in ASU 2014-12 are effective for annual periods beginning after December 15, 2015 and interim periods within those annual periods with early adoption permitted. Entities may apply the amendments in ASU 2014-12 either: (a) prospectively to all awards granted or modified after the effective date; or (b) modified retrospectively to all awards with performance targets that are outstanding on or after the beginning of the first annual period presented as of the adoption date. ASU 2014-12 is not applicable to the Company’s current stock based compensation plan and it does not expect this guidance to have any impact on the consolidated financial statements.

In August 2014, the FASB issued ASU No. 2014-15, “Presentation of Financial Statements (Subtopic 205-40), Disclosure of Uncertainties about an Entity’s Ability to Continue as a Going Concern” (“ASU 2014-15”) . ASU 2014-15 requires management to evaluate whether there are conditions and events that raise substantial doubt about the entity’s ability to continue as a going concern within one year after the financial statements are issued and, if so, disclose that fact. Such evaluation is to be done for both annual and interim reporting periods, if applicable. Management is also required to evaluate and disclose whether its plans alleviate that doubt. The Company adopted the ASU 2014-15 and the new guidance did not have any impact on the Company’s consolidated financial statements.

In November 2014, the FASB issued ASU No. 2014-17, “Business Combinations (Topic 805): Pushdown Accounting, a consensus of the FASB Emerging Issues Task Force (“ASU 2014-17”). The amendments in this Update provide an acquired entity with an option to apply pushdown accounting in its separate financial statements upon occurrence of an event in which an acquirer obtains control of the acquired entity. An acquired entity may elect the option to apply pushdown accounting in the reporting period in which the change-in-control event occurs. An acquired entity should determine whether to elect to apply pushdown accounting for each individual change-in-control event in which an acquirer obtains control of the acquired entity. If pushdown accounting is not applied in the reporting period in which the change-in-control event occurs, an acquired entity will have the option to elect to apply pushdown accounting in a subsequent reporting period to the acquired entity’s most recent change-in-control event. An election to apply pushdown accounting in a reporting period after the reporting period in which the change-in-control event occurred should be considered a change in accounting principle in accordance with Topic 250, Accounting Changes and Error Corrections. If pushdown accounting is applied to an individual change-in-control event, that election is irrevocable. The amendments in this Accounting Standards Update are effective on November 18, 2014. After the effective date, an acquired entity can make an election to apply the guidance to future change-in-control events or to its most recent change-in-control event. However, if the financial statements for the period in which the most recent change-in-control event occurred already have been issued or made available to be issued, the application of this guidance would be a change in accounting principle. The adoption of ASU 2014-17 did not have a material impact on the Company’s consolidated financial statements.

Segment Reporting [Abstract]

Segment Information

4. Segment Information

The Company’s business is divided into two reporting segments: Operations Management (previously called Outsourcing Services) and Analytics and Business Transformation (previously called Transformation Services). The Company changed its reporting segment nomenclature in 2014 in order to more accurately reflect the changing nature of its engagements with the clients. For comparability with the prior periods, the business composition of each segment remains unchanged.

The Company provides various types of business process solutions utilizing Operations Management, analytics and technology. 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 its two segments, 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. The Company’s recent acquisition of Blue Slate Solutions, LLC (“Blue Slate”) and Overland Holdings, Inc. (“Overland”) are classified within the Analytics and Business Transformation and Operations Management, respectively.

Revenues and cost of revenues for each of the years ended December 31, 2014, 2013 and 2012, for Operations Management and Analytics and Business Transformation segments, respectively, are as follows:

Business Combinations, Goodwill and Intangible Assets

5. Business Combinations, Goodwill and Intangible Assets

a) Blue Slate Solutions, LLC

On July 1, 2014, the Company entered into a membership interest purchase agreement (the “Agreement”) with Blue Slate, a provider of Business Process Management and Technology Solutions that specializes in transforming operations through business process automation, use of innovative technologies, data integration and analytics. Pursuant to the Agreement, the Company has purchased all of the membership interests of Blue Slate for a cash consideration of $6,986, including working capital adjustments of $751.

Blue Slate’s approach bolsters the Company’s strategy of embedding process automation and operational analytics into client offerings. As the Company pursues this approach through Business EXLerator Framework^TM, Blue Slate brings the ability to work directly on clients’ core, mission-critical applications inside their IT environments to transform their business processes. This strengthens the Company’s position with regard to IT services providers that have strong technology foundations and enriches the Company’s value proposition to clients in addition to using the Company’s capabilities to deliver greater impact for its client base. 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 Company’s purchase price allocation for the acquisition is as follows:


	Amount
	(In thousands)
Net tangible assets	$	1,313
Identifiable intangible assets:
Customer relationships		804
Non-compete agreement		48
Trade Names & Trademarks		267
Goodwill		4,554

Total purchase price*	$	6,986

Includes $750 deposited in escrow accounts in connection with the acquisition.

The customer relationships, non-compete agreements and trade names and trademarks intangibles from the Blue Slate acquisition are being amortized over a useful life of five years, four years and three years, respectively.

During the year ended December 31, 2014 the company recognized $125 of acquisition related costs. Such amounts are included under general and administrative expenses in the consolidated statements of income. The Company’s results of operations for the year ended December 31, 2014 includes $4,378 of revenues of Blue Slate since July 1, 2014, the date on which acquisition was consummated. It is not practicable to disclose the net earnings since management does not allocate or evaluate operating expenses and income taxes to its domestic entities.

The amount of goodwill recognized from the Blue Slate acquisition is deductible for tax purposes.

b) Overland Holdings, Inc.

On October 24, 2014, the Company acquired all of the outstanding shares of Overland Holdings, Inc. (“Overland”) pursuant to a Plan of Merger (the “Merger”).

The aggregate consideration for Overland’s acquisition was $65,940 (“Merger Consideration), including working capital adjustments of $12,940. The Merger Consideration was paid with existing cash on the Company’s balance sheet. A portion of the Merger Consideration otherwise payable in the Merger was placed into escrow as security for post-closing working capital adjustments and the indemnification obligations under the Merger Agreement.

Overland, now as subsidiary of the Company is a leader in underwriting support services for Property & Casualty (“P&C”) insurers. It leverages proprietary workflow and automation technology, alongside transaction-based-pricing models to offer a well client demand aligned Business-process-as-a-service (BPaaS) solutions. Overland’s longstanding client relationships, experienced leadership team and technology-enabled services will enhance Company’s market leading position in Operations Management to P&C insurers and also strengthens Company’s onshore delivery capabilities. Overland’s technology and data directly connects and interfaces with its clients providing a truly integrated Operations Management solution. The acquisition presents an enormous opportunity to leverage Company’s analytics capabilities to enable Overland’s clients to increase the effectiveness of their underwriting. 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 Company’s preliminary purchase price allocation for the acquisition is as follows:


	Amount
	(In thousands)
Net tangible assets	$	18,873
Identifiable intangible assets:
Customer relationships		12,200
Developed Technology		4,800
Trade Names & Trademarks		1,400
Goodwill		28,667

Total purchase price*	$	65,940

Includes amount of $4,550 deposited in escrow accounts in connection with the acquisition.

The customer relationships, trade names and trademarks and developed technology from the Overland acquisition are being amortized over a useful life of twelve, ten years and five years, respectively.

Under ASC topic 805, “Business Combinations,” the preliminary allocation of the purchase price to the tangible and intangible assets and liabilities acquired may change up to a period of one year from the date of the acquisition. Accordingly, the Company may adjust the amounts recorded as of December 31, 2014 to reflect any revised valuations of the assets acquired or liabilities assumed. The Company’s purchase accounting as of December 31, 2014 was incomplete primarily due to the valuation of intangibles as of the acquisition date.

During the year ended December 31, 2014 the company recognized $309 of acquisition related costs. Such amounts are included under general and administrative expenses in the consolidated statements of income. The Company’s results of operations for the year ended December 31, 2014 includes $12,246 of revenues of Overland since October 24, 2014, the date on which acquisition was consummated. It is not practicable to disclose the net earnings since management does not allocate or evaluate operating expenses and income taxes to its domestic entities.

The amount of goodwill recognized from the Overland acquisition is deductible for tax purposes.

Fair Value Disclosures [Abstract]

Fair Value Measurements

6. Fair Value Measurements

ASC topic 820, “Fair Value Measurements and Disclosures” (ASC No. 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 No. 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, 2014 and 2013. The table excludes short-term investments, accounts receivable, accounts payable and accrued expenses for which fair values approximate their carrying amounts.

Assets and Liabilities Measured at Fair Value

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 No. 815. The Company also enters into foreign currency forward contracts to economically hedge its intercompany balances and other monetary assets and liabilities denominated in currencies other than functional currencies. These derivatives do not qualify as fair value hedges under ASC No. 815. Changes in the fair value of these derivatives are recognized in the consolidated statements of income and are included in foreign exchange loss. The Company’s primary exchange rate exposure is with the Indian Rupee, the U.K. pound sterling and the Philippine peso. The Company also has exposure to Czech koruna and other local currencies in which it operates.

The Company had outstanding foreign exchange contracts totaling $276,018 and GBP 10,889 as of December 31, 2014 and totaling $262,085 and GBP 10,973 as of December 31, 2013. The Company estimates that approximately $1,142 of net derivative losses included in accumulated other comprehensive loss (“AOCI”) could be reclassified into earnings within the next twelve months based on exchange rates prevailing as of December 31, 2014. At December 31, 2014, 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. 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, 2014 and 2013.

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,
	2014		2013
Other current assets:
Foreign currency exchange contracts	$	1,243	$	437

Accrued expenses and other current liabilities:

Capital Structure	9. Capital Structure *Common Stock* The Company has one class of common stock outstanding. During the year ended December 31, 2014 and 2013, the Company acquired 18,256 and 13,018 shares of common stock, respectively from employees in connection with withholding tax payments related to the vesting of restricted stock for a total consideration of $459 and $389, respectively. The weighted average purchase price of $25.14 and $29.89, respectively was the average of the high and low price of the Company’s share of common stock on the Nasdaq Global Select Market on the trading day prior to the vesting date of the shares of restricted stock. The shares acquired are held as treasury stock. On December 30, 2014, the Company’s Board of Directors authorized up to an annual $20 million common stock repurchase program (the “2014 Repurchase Program”), under which shares may be purchased by the Company from time to time from the open market and through private transactions during each of the fiscal years 2015 to 2017. On November 7, 2013, the Company had announced a similar program, pursuant to which the Board of Directors authorized a $25 million common stock repurchase program (the “2013 Repurchase Program”), under which shares may be purchased by the Company from time to time from the open market and through private transactions. Repurchased shares under these programs are recorded as treasury shares and will be held until the Board of Directors designates that these shares be retired or used for other purposes. During the year ended December 31, 2014, the Company purchased 109,500 shares of its common stock for an aggregate purchase price of approximately $2,863 including commissions, representing an average purchase price per share of $26.14 under the 2013 Repurchase program. During the year ended December 31, 2013, the Company purchased 820,849 shares of its common stock for an aggregate purchase price of approximately $21,229 including commissions, representing an average purchase price per share of $25.86 under the 2013 Repurchase program.

Debt Disclosure [Abstract]
Borrowings	10. Borrowings On October 24, 2014, the Company entered into a credit agreement (the “Credit Agreement”) with certain lenders and JPMorgan Chase Bank, N.A., as Administrative Agent. The Credit Agreement provides for a $50,000 revolving credit facility (the “Credit Facility”), including a letter of credit sub-facility, for a period of five years. The Company has an option to increase the commitments under the Credit Facility by up to an additional $50,000, subject to certain approvals and conditions as set forth in the Credit Agreement. The credit facility has a maturity date of October 24, 2019 and is voluntarily prepayable from time to time without premium or penalty. Borrowings under the Credit Facility may be used for working capital and general corporate purposes. The Company availed the entire $50,000 under the Credit Facility during the year ended December 31, 2014 and, as of December 31, 2014, the borrowings under the Credit Facility are shown as a long-term borrowing in the consolidated balance sheet. In connection with the financing, the Company incurred $444 as debt issuance costs, which are deferred and amortized as an adjustment to interest expense over the term of the Credit Facility on a straight line basis. Borrowings under the Credit Agreement bear interest at a rate equal to the specified prime rate (alternate base rate) or adjusted LIBO rate, plus, an applicable margin. The applicable margin is tied to the Company’s leverage ratio and ranges from 0.25% to 0.75% per annum with respect to loans (“ABR Loans”) pegged to the specified prime rate, and 1.25% to 1.75% per annum on loans (“Eurodollar Loans”) pegged to the adjusted LIBO rate (such applicable margin, the “Applicable Rate”). The revolving credit commitments under the Credit Agreement are subject to a commitment fee. The commitment fee is also tied to the Company’s leverage ratio, and ranges from 0.20% to 0.30% per annum on the average daily amount by which the aggregate revolving commitments exceed the sum of outstanding revolving loans and letter of credit obligations. The credit facility carried an interest rate of 1.5% per annum during the year ended December 31, 2014. The Credit Facility is guaranteed by the Company’s domestic subsidiaries and material foreign subsidiaries. The obligations under the Credit Agreement are secured by all or substantially all of the assets of the Company and its material domestic subsidiaries. The Credit Agreement contains certain covenants including a restriction on indebtedness of the Company.

Employee Benefit Plans

11. Employee Benefit Plans

The Company’s Gratuity Plans in India and the Philippines provide for lump sum payment to vested employees on retirement or upon 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, 2014. The following table sets forth the activity and the funded status of the Gratuity Plans and the amounts recognized in the Company’s consolidated financial statements at the end of the relevant periods:

Tax expense	$	5,193		$	16,880		$	14,884

The effective tax rate decreased from 26.0% for the year ended December 31, 2013 to 13.8% for the year ended December 31, 2014, primarily due to the reversal of an unrecognized tax benefit of $2,173 in foreign tax jurisdictions during the year ended December 31, 2014 as a result of judicial rulings handed down during the year involving unaffiliated companies regarding similar tax matters. In the Company’s judgment, such rulings increased the level of certainty that its position on these tax adjustments proposed by the tax authorities would more likely than not be resolved in favor of the Company. The effective tax rate was further decreased during the year ended December 31, 2014 due to federal losses in the U.S. related to the reimbursement of disentanglement costs to Travelers under the Services Agreement. The federal losses are expected to be carried back to the prior year tax return and result in a current tax benefit of $1,934 (refer to Item 2—“Management’s Discussion and Analysis of Financial Condition and Results of Operations” for further details).

The Company also benefits from a corporate tax holiday in the Philippines for its operations centers established there over the last six years. The tax holiday expired for one of its centers in 2014 and will expire over the next few years for other centers, which may lead to an increase in our overall effective tax rate of the Company. Following the expiry of the tax exemption, income generated from centers in Philippines will be taxed at the prevailing annual tax rate, which is currently 5% on gross income.

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. These delivery centers are eligible for a 100% income tax exemption till 31 March 2015 and 50% income tax exemption with effect from 1 April 2015 for a period of five years thereafter. As part of the Company’s acquisition of Business Process Outsourcing Inc. in May 2011 (“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 new operations centers in Pune, India in 2012 and in Kochi, India in 2013 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 $0.10, $0.16 and $0.10 for the years ended December 31, 2014, 2013 and 2012, respectively.

The components of the deferred tax balances as of December 31, 2014 and 2013 are as follows:

Deferred tax liabilities:	$	12,640		$	13,170

Net deferred tax assets	$	16,440		$	19,212

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, 2014 and 2013, 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, 2014 and 2013. The Company also recorded a valuation allowance of $64 related to tax credit carry forward during the year ended December 31, 2014.

As a result of the multiple acquisitions over the last few years, the Company acquired federal and state net operating losses in the United States. Thus, as of December 31, 2014 and 2013, the Company has federal net operating loss carry forwards of approximately $25,300 and $26,900 respectively, which expire through various years until 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.

At December 31, 2014 and 2013, 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 $222,292 and $185,596 as of December 31, 2014 and 2013, respectively.

The Company’s income tax expense also includes the impact of provisions established for uncertain income tax positions determined in accordance with ASC topic 740, “Income Taxes” (“ASC No. 740”), 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 income tax expense 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, 2014 through December 31, 2014:


Balance as of January 1, 2014	$	4,913
Increases related to prior year tax positions		—

Increases related to current year tax positions		—
Decreases related to current year tax positions		—
Effect of exchange rate changes		21

Balance as of December 31, 2014	$	2,761

The unrecognized tax benefits as of December 31, 2014 of $2,761, if recognized, would impact the effective tax rate.

The Company has recognized interest of $276 and $283 during the year ended December 31, 2014 and 2013, respectively, which is included in the income tax expense in the consolidated statements of income. As of December 31, 2014 and 2013, the Company has accrued interest and penalties of $1,117 and $863 relating to unrecognized tax benefits.

The unrecognized tax benefits may increase or decrease in the next twelve months depending on the Company’s tax positions.

Stock Based Compensation

14. 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 and market condition based 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, 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.

Stock Options

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


	Year ended December 31,
	2014		2013		2012
Cost of revenue	$	2,290	$	2,413	$	1,893
General and administrative expenses		4,350		5,077		4,551
Selling and marketing expenses		4,371		4,342		2,972

Total	$	11,011	$	11,832	$	9,416

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,
	2014			2013			2012
Dividend yield		0	%		0	%		0	%
Expected life (years)		5.50			5.50			5.38
Risk free interest rate		1.84	%		0.87	%		0.97	%
Volatility		35	%		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.

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:

The fair value of restricted stock and restricted stock units is generally the market price of the Company’s shares on the date of grant. As of December 31, 2014, unrecognized compensation cost of $24,712 is expected to be expensed over a weighted average period of 2.56 years. The weighted-average fair value of restricted stock and restricted stock units granted during the years ended December 31, 2014, 2013 and 2012 was $26.47, $29.37 and $25.07, respectively. The total grant date fair value of restricted stock and restricted stock units vested during the years ended December 31, 2014, 2013 and 2012 was $11,393, $9,126 and $7,010, respectively.

During the year ended December 31, 2014, the Company granted 46,950 restricted stock and 87,650 restricted stock units in connection with the Blue Slate and Overland acquisitions, respectively. The fair value of these grants will be recognized as compensation expense over the vesting period.

Performance Based Stock Awards

The Monte-Carlo simulation model simulates a range of possible future stock prices and estimates the probabilities of the potential payouts. This model also incorporates the following ranges of assumptions:

•

The historical volatilities are used over the most recent three-year period for the components of the peer group.

•

The risk-free interest rate is based on the U.S. Treasury rate assumption commensurate with the three-year performance period.

•

Since the plan stipulates that the awards are based upon the TSR of the Company and the components of the peer group, it is assumed that the dividends get reinvested in the issuing entity on a continuous basis.

•

The correlation coefficients are used to model the way in which each entity tends to move in relation to each other are based upon the price data used to calculate the historical volatilities.

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

As of December 31, 2014, unrecognized compensation cost of $2,086 is expected to be expensed over a weighted average period of two years.

Subsequent to December 31, 2014, the Company granted approximately 127,000 PRSUs and 336,000 restricted stock units to its employees.

Commitments and Contingencies Disclosure [Abstract]
Commitments and Contingencies	16. Commitments and Contingencies *Fixed Asset Commitments* At December 31, 2014, the Company has committed to spend approximately 12,200 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 or under the Software Technology Parks of India (“STPI”) scheme promulgated by the Government of India. These units are exempt from customs, central excise duties, and levies on imported and indigenous capital goods, stores, and spares. The Company has undertaken to pay custom duties, service taxes, levies, and liquidated damages payable, if any, in respect of imported and indigenous capital goods, stores and spares consumed duty free, in the event that certain terms and conditions are not fulfilled. 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 the Philippine Economic Zone Authority (“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 2011 and its permanent establishment issues ranging from tax years 2003 to 2007 as of December 31, 2014 and 2013 is $22,866 and $14,742, respectively of which the Company has already made payment or provided bank guarantee to the extent $14,666 and $13,797, respectively. Subsequent to December 31, 2014, the Company received tax demands from the Income tax authorities of $1,235 related to the tax year 2011 for some of its foreign subsidiaries. Amounts paid as deposits in respect of such assessments aggregating to $12,564 and $11,653 as of December 31, 2014 and 2013, respectively, are included in “Other assets” and amounts deposited for bank guarantees aggregating to $2,102 and $2,144 as of December 31, 2014 and 2013, respectively, are included in “Restricted cash” in the non-current assets section of the Company’s consolidated balance sheets as of December 31, 2014 and 2013. Based on advice from its Indian tax advisors, the facts underlying the Company’s position and its experience with these types of assessments, the Company believes that the probability that it will ultimately be found liable for these assessments 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 or assessments from tax authorities for subsequent years. Accordingly even if these disputes are resolved, the Indian tax authorities may still serve additional orders or assessments.

Business Combinations, Goodwill and Intangible Assets

a) Blue Slate Solutions, LLC

Blue Slate’s approach bolsters the Company’s strategy of embedding process automation and operational analytics into client offerings. As the Company pursues this approach through Business EXLerator Framework, Blue Slate brings the ability to work directly on clients’ core, mission-critical applications inside their IT environments to transform their business processes. This strengthens the Company’s position with regard to IT services providers that have strong technology foundations and enriches the Company’s value proposition to clients in addition to using the Company’s capabilities to deliver greater impact for its client base. 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 Company’s purchase price allocation for the acquisition is as follows:


	Amount
	(In thousands)
Net tangible assets	$	1,313
Identifiable intangible assets:
Customer relationships		804
Non-compete agreement		48
Trade Names & Trademarks		267
Goodwill		4,554

Total purchase price*	$	6,986

*	Includes $750 deposited in escrow accounts in connection with the acquisition.

During the year ended December 31, 2014 the company recognized $125 of acquisition related costs. Such amounts are included under general and administrative expenses in the consolidated statements of income. The Company’s results of operations for the year ended December 31, 2014 includes $4,378 of revenues of Blue Slate since July 1, 2014, the date on which acquisition was consummated. It is not practicable to disclose the net earnings since the management does not allocate or evaluate operating expenses and income taxes to its domestic entities.

The amount of goodwill recognized from the Blue Slate acquisition is deductible for tax purposes.

b) Overland Holdings, Inc.

On October 24, 2014, the Company acquired the shares of Overland Holdings, Inc. (“Overland”) pursuant to a Plan of Merger (the “Merger”).

Overland is a leader in underwriting support services for Property & Casualty (“P&C”) insurers. It leverages proprietary workflow and automation technology, alongside transaction-based-pricing models to offer a well client demand aligned Business-process-as-a-service (BPaaS) solutions. Overland’s longstanding client relationships, experienced leadership team and technology-enabled services will enhance Company’s market leading position in Operations Management to P&C insurers and also strengthens Company’s onshore delivery capabilities. Overland’s technology and data directly connects and interfaces with its clients providing a truly integrated Operations Management solution. The acquisition presents an enormous opportunity to leverage Company’s analytics capabilities to enable Overland’s clients to increase the effectiveness of their underwriting. 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 Company’s preliminary purchase price allocation for the acquisition is as follows:


	Amount
	(In thousands)
Net tangible assets	$	18,873
Identifiable intangible assets:
Customer relationships		11,200
Developed Technology		4,800
Trade Names & Trademarks		1,400
Goodwill		29,667

Total purchase price*	$	65,940

*	Includes amount of $4,550 deposited in escrow accounts in connection with the acquisition.

The customer relationships, trade names and trademarks and developed technology from the Overland acquisition are being amortized over a useful life of twelve, ten years and five years, respectively.

Under ASC topic 805, “Business Combinations,” the preliminary allocation of the purchase price to the tangible and intangible assets and liabilities acquired may change up to a period of one year from the date of the acquisition. Accordingly, the Company may adjust the amounts recorded as of December 31, 2014 to reflect any revised valuations of the assets acquired or liabilities assumed. The Company’s purchase accounting as of December 31, 2014 was incomplete primarily due to the valuation of intangibles as of the acquisition date.

During the year ended December 31, 2014 the company recognized $309 of acquisition related costs. Such amounts are included under general and administrative expenses in the consolidated statements of income. The Company’s results of operations for the year ended December 31, 2014 includes $12,246 of revenues of Overland since October 24, 2014, the date on which acquisition was consummated. It is not practicable to disclose the net earnings since the management does not allocate or evaluate operating expenses and income taxes to its domestic entities.

The amount of goodwill recognized from the Overland acquisition is deductible for tax purposes.
