Summary of Significant Accounti

Accounting Policies [Abstract]
Summary of Significant Accounting Policies	Summary of Significant Accounting Policies (a) Basis of Preparation and Principles of Consolidation The unaudited consolidated financial statements have been prepared in conformity with United States generally accepted accounting principles (“U.S. GAAP”) for interim financial information, the instructions to Form 10-Q and Article 10 of Regulation S-X. Accordingly, they do not include all of the information and footnotes required by U.S. GAAP for annual financial statements and therefore should be read in conjunction with the audited consolidated financial statements and footnotes thereto included in the Company’s Annual Report on Form 10-K for the fiscal year ended December 31, 2021. The unaudited consolidated financial statements reflect all adjustments (of a normal and recurring nature) that management considers necessary for a fair presentation of such statements for the interim periods presented. The unaudited consolidated statements of income for the interim periods presented are not necessarily indicative of the results for the full year or for any subsequent period. The accompanying unaudited consolidated financial statements include the financial statements of ExlService Holdings and all of its subsidiaries. The standalone financial statements of subsidiaries are fully consolidated on a line-by-line basis. Intra-group balances and transactions, and gains and losses arising from intra-group transactions, are eliminated while preparing consolidated financial statements. Accounting policies of the respective individual subsidiary and associate are aligned wherever necessary, so as to ensure consistency with the accounting policies that are adopted by the Company under U.S. GAAP. The Company’s investments in equity affiliates are initially recorded at cost and any excess purchase consideration paid over proportionate share of the fair value of the net assets of the investee at the acquisition date is recognized as goodwill. The proportionate share of net income or loss of the investee after its acquisition is recognized in the unaudited consolidated statements of income. (b) Use of Estimates The preparation of the unaudited consolidated financial statements in conformity with U.S. 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 unaudited consolidated financial statements and the unaudited 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 unaudited consolidated financial statements include, but are not limited to, estimates of the fair value of the identifiable intangible assets and contingent consideration, purchase price allocation, including revenue projections and discount rate applied within the discounted cash flow model for business acquisitions, allowance for expected credit losses, the nature and timing of the satisfaction of performance obligations, the standalone selling price of performance obligations, and variable consideration in a customer contract, expected recoverability from customers with contingent fee arrangements, estimated costs to complete fixed price contracts, recoverability of dues from statutory authorities, assets and obligations related to employee benefit plans, deferred tax valuation allowances, income-tax uncertainties and other contingencies, valuation of derivative financial instruments, assumptions used to calculate stock-based compensation expense, assumptions used to determine the incremental borrowing rate to calculate lease liabilities and right-of-use (“ROU”) assets, lease term to calculate amortization of ROU, depreciation and amortization periods, and recoverability of long-lived assets, goodwill and intangibles. (c) Recent Accounting Pronouncements In March 2020, the Financial Accounting Standards Board (“FASB”) issued Accounting Standard Update (“ASU”) No. 2020-04, Reference Rate Reform (Topic 848): Facilitation of the Effects of Reference Rate Reform on Financial Reporting. This ASU provides optional guidance for a limited period of time to ease potential accounting impacts associated with transitioning away from reference rates that are expected to be discontinued, such as interbank offered rates and London Inter-Bank Offered Rate (“LIBOR”). The ASU provides practical expedients and exceptions for applying U.S. GAAP to contracts, hedging relationships, and other transactions affected by reference rate reform if certain criteria are met. The amendments are elective and are effective upon issuance for all entities through December 31, 2022. The Company is currently evaluating the impact of this ASU on its consolidated financial statements. In October 2021, FASB issued ASU No. 2021-08, Business Combinations (Topic 805): Accounting for Contract Assets and Contract Liabilities from Contracts with Customers . This ASU provides guidance in Topic 805 to require the acquirer entity to recognize and measure contract assets and contract liabilities acquired in a business combination in accordance with Topic 606, Revenue from Contracts with Customers , as if it had originated the contracts. Generally, this should result in an acquirer recognizing and measuring the acquired contract assets and contract liabilities consistent with how they were recognized and measured in the acquiree’s financial statements, if the acquiree prepared financial statements in accordance with U.S. GAAP. The ASU is effective for fiscal years beginning after December 15, 2022. An entity may early adopt the ASU including adoption in an interim period, with retrospective application to all business combinations within the fiscal year that includes such interim period. The Company is currently evaluating the impact of this ASU on its consolidated financial statements.

Segment Reporting [Abstract]
Segment and Geographical Information	Segment and Geographical Information The Company is a provider of data analytics and digital operations and solutions. The Company manages and reports financial information through its four reportable segments: Insurance, Healthcare, Analytics and Emerging Business, which reflects how management reviews financial information and makes operating decisions. These business units develop client-specific solutions, build capabilities, maintain a unified go-to-market approach and are integrally responsible for service delivery, customer satisfaction, growth and profitability. The chief operating decision maker (“CODM”) generally reviews financial information such as revenues, cost of revenues and gross profit, disaggregated by the operating segments to allocate an overall budget among the operating segments. The Company does not allocate and therefore the CODM does not evaluate, certain operating expenses, interest expense or income taxes by segment. Many of the Company’s assets are shared by multiple operating segments. The Company manages these assets on a total Company basis, not by operating segment, and therefore asset information and capital expenditures by operating segment are not presented. The December 2021 acquisition of Clairvoyant AI Inc. (“Clairvoyant”) is included in the Analytics reportable segment. Refer to Note 9 - Business Combination, Goodwill and Intangible Assets to the unaudited consolidated financial statements for further details. Revenues and cost of revenues for the three months ended March 31, 2022 and 2021, respectively, for each of the reportable segments, are as follows: Three months ended March 31, 2022 Insurance Healthcare Emerging Business Analytics Total Revenues, net $ 103,266 $ 26,156 $ 50,747 $ 149,039 $ 329,208 Cost of revenues (1) 65,082 17,651 29,213 95,570 207,516 Gross profit (1) $ 38,184 $ 8,505 $ 21,534 $ 53,469 $ 121,692 Operating expenses 77,717 Foreign exchange gain, interest expense and other income, net 3,291 Income tax expense 11,202 Gain from equity-method investment 114 Net income $ 36,178 (1) Exclusive of depreciation and amortization expense.

Revenue from Contract with Customer [Abstract]
Revenues, net	Revenues, net Refer to Note 3 - Segment and Geographical Information to the unaudited consolidated financial statements for revenues disaggregated by reportable segments and geography. Contract balances The following table provides information about accounts receivable, contract assets and contract liabilities from contracts with customers: As of March 31, 2022 December 31, 2021 Accounts receivable, net $ 239,279 $ 194,232 Contract assets $ 2,150 $ 2,524 Contract liabilities: Deferred revenue (consideration received in advance) $ 19,765 $ 18,247 Consideration received for process transition activities $ 3,138 $ 2,203 Accounts receivable includes $123,123 and $93,336 as of March 31, 2022 and December 31, 2021, respectively, representing unbilled receivables. The Company has accrued the unbilled receivables for work performed in accordance with the terms of contracts with customers and considers no significant performance risk associated with its unbilled receivables. Contract assets represent upfront payments such as deal signing discounts or deal signing bonuses made to customers. These costs are amortized over the expected period of the benefit and are recorded as an adjustment to transaction price and reduced from revenues. The Company’s assessment did not indicate any impairment losses on its contract assets for the periods presented. Contract liabilities represent that portion of deferred revenue for which payments have been received in advance from customers. The Company also defers revenues attributable to certain process transition activities for which costs have been capitalized by the Company as contract fulfillment costs.

Earnings Per Share [Abstract]
Earnings Per Share	Earnings Per Share Basic earnings per share is computed by dividing net income attributable to common stockholders by the weighted average number of common shares outstanding, adjusted for outstanding shares that are subject to repurchase 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 (outstanding stock options, restricted stock and restricted stock units) issued and outstanding at the reporting date, and an assumed conversion premium of outstanding convertible notes, using the treasury stock method (as discussed further in the subsequent paragraph). Common stock equivalents that are anti-dilutive are excluded from the computation of weighted average shares outstanding. The Company includes performance stock unit awards in dilutive potential common shares when they become contingently issuable and have a dilutive impact per authoritative guidance and excludes such awards when they are not contingently issuable. In 2021, diluted weighted-average shares outstanding was affected by the treatment of the Company's 3.5% per annum Convertible Senior Notes due October 1, 2024 (the “Notes”). The Company had a choice to settle the Notes in cash, shares or any combination of the two. The Company had the ability to settle the principal balance of the Notes in cash, and as such, the Company applied the treasury stock method. The dilution related to the conversion premium, if any, of the Notes is included in the calculation of diluted weighted-average shares outstanding for the portion of the period until actual settlement and to the extent the issuance is dilutive based on the average stock price during the reporting period being greater than the conversion price of $75. During the third quarter of 2021, the Company settled the Notes by electing a combination of cash and shares of the Company’s common stock and as such included the count of shares issued on settlement in the calculation of basic earnings per share for the portion of the period outstanding. The following table sets forth the computation of basic and diluted earnings per share: Three months ended March 31, 2022 2021 Numerators: Net income $ 36,178 $ 31,931 Denominators: Basic weighted average common shares outstanding 33,442,038 33,734,118 Dilutive effect of share based awards 452,830 342,993 Dilutive effect of conversion premium on the Notes — 241,207 Diluted weighted average common shares outstanding 33,894,868 34,318,318 Earnings per share attributable to ExlService Holdings Inc. stockholders: Basic $ 1.08 $ 0.95 Diluted $ 1.07 $ 0.93 Weighted average potentially dilutive shares considered anti-dilutive and not included in computing diluted earnings per share 1,082 —

During the three months ended March 31, 2022, there were no changes in estimated useful lives of property and equipment during the ordinary course of operations. The depreciation and amortization expense, excluding amortization of acquisition-related intangibles, recognized in the unaudited consolidated statements of income was as follows: Three months ended March 31, 2022 2021 Depreciation and amortization expense $ 9,116 $ 8,740 The effect of foreign exchange gain upon settlement of cash flow hedges recorded under depreciation and amortization, was as follows: Three months ended March 31, 2022 2021 Effect of foreign exchange gain $ 67 $ 165 Internally developed software costs, included under Software, was as follows: As of March 31, 2022 December 31, 2021 Cost $ 25,977 $ 19,289 Less : Accumulated amortization (11,265) (10,226) Internally developed software, net $ 14,712 $ 9,063 The amortization expense on internally developed software recognized in the unaudited consolidated statements of income was as follows: Three months ended March 31 2022 2021 Amortization expense $ 1,033 $ 1,024 As of March 31, 2022 and December 31, 2021, the Company believes no impairment exists because the long-lived asset's future undiscounted net cash flows expected to be generated exceeds its carrying value; however, there can be no assurances that long-lived assets will not be impaired in future periods. Determining whether an impairment has occurred typically requires various estimates and assumptions, including determining which undiscounted cash flows are directly related to the potentially impaired asset, the useful life over which cash flows will occur, their amount, and the asset’s residual value, if any. It is reasonably possible that the judgments and estimates described above could change in future periods. The duration and severity of COVID-19 and continued market volatility is highly uncertain and, as such, the impact on undiscounted cash flows is subject to significant judgment and may cause variability in the Company’s assessment of the existence of any impairment.

Goodwill and Intangible Assets Disclosure [Abstract]
Business Combinations	Business Combination, Goodwill and Intangible Assets Clairvoyant AI Inc. On December 16, 2021, the Company, through its wholly owned subsidiary ExlService.com, LLC (“Buyer”), completed the acquisition of Clairvoyant, a Delaware corporation, pursuant to an equity securities purchase agreement dated December 16, 2021 (the "Purchase Agreement"). The Company purchased 100% of the issued and outstanding equity securities in Clairvoyant. Clairvoyant is a global technology consulting and services company that helps organizations in their business transformation by maximizing the value of data through actionable insights. It provides data engineering, analytics, machine learning, product engineering, and cloud-based solutions. The acquisition strengthens the Company’s capabilities by adding additional expertise in data engineering and cloud enablement, further supporting its clients in insurance, healthcare, banking and financial services, and retail. The base purchase consideration payable at Closing was $80,080, excluding cash and cash equivalents acquired, debt and other estimated post-closing adjustments. As of March 31, 2022 and December 31, 2021, of the total purchase consideration, the Company has paid $78,198 and $76,831, respectively, net of cash and cash equivalents acquired. The Purchase Agreement also allows sellers the ability to earn up to $20,000 in earn-out payments, based on the achievement of certain performance goals by Clairvoyant during 2022 and 2023 calendar years. The earn-out has an estimated fair value of $9,000 and has been presented as contingent consideration under “Other non-current liabilities” and “Accrued expenses and other current liabilities,” as applicable, as of March 31, 2022 and December 31, 2021 in the consolidated balance sheets. A portion of the purchase consideration otherwise payable was placed into escrow as security for the post-closing working capital adjustments and the indemnification obligations under the Purchase Agreement. To finance the acquisition at Closing, the Company utilized its revolving Credit Facility in the amount of $75,000 and paid the balance with available cash on hand. The Company accounted for the business combination using the acquisition method of accounting. The measurement period will not exceed one year from the acquisition date. Pursuant to the Company’s business combinations accounting policy, the aggregate purchase consideration for Clairvoyant was allocated to identifiable net tangible and intangible assets based upon their preliminary fair values. The excess of the estimated purchase consideration over fair value of identifiable net tangible and intangible assets was recorded as goodwill. In order to allocate the consideration transferred for Clairvoyant, the fair values of all identifiable assets and liabilities must be established. For accounting and financial reporting purposes, fair value is defined under ASC No. 820, Fair Value Measurement and Disclosure, as the price that would be received upon sale of an asset or the amount paid to transfer a liability in an orderly transaction between market participants at the measurement date. Market participants are assumed to be buyers and sellers in the principal (most advantageous) market for the asset or liability. Additionally, fair value measurements for an asset assume the highest and best use of that asset by market participants. Use of different estimates and judgments could yield different results. The Company’s preliminary purchase price allocation to net tangible and intangible assets of Clairvoyant as of December 16, 2021 was as follows: Assets: Cash and cash equivalents $ 5,606 Accounts receivable, net 9,042 Other current assets 352 Property and equipment, net 399 Intangible assets, net Customer relationships 31,600 Developed technology 2,070 Trade names and trademarks 300 Non-compete agreements 300 Other assets 216 Total assets $ 49,885 Liabilities: Accounts payable $ (1,241) Accrued expenses and other current liabilities (4,833) Deferred tax liabilities (9,383) Other non-current liabilities (1,226) Total liabilities (16,683) Net assets acquired 33,202 Goodwill 56,373 Total purchase consideration* $ 89,575 * Includes contingent consideration of $9,000 recognized at fair value. The fair value of assets acquired and liabilities assumed from the acquisition of Clairvoyant is based on a preliminary valuation and, as such, the Company's estimates and assumptions are subject to change within the measurement period. The primary areas of the purchase price allocation that are not yet finalized are related to post-closing working capital and debt adjustments and reflect management’s best estimates and assumptions as of the reporting date. During the three months ended March 31, 2022, the Company recognized measurement period adjustments, which led to increase in goodwill in an amount of $1,148. The adjustments related to measurement of favorable lease intangibles of $160 included under “other assets” and reserves for various tax matters of $988 included under “other current liabilities.” The fair values of customer relationships were determined by using an “income approach,” specifically the Multi-Period Excess Earnings Method. The customer relationship assets are being amortized on a straight-line basis (which approximates the economic pattern of benefits) over the estimated economic life of 7 years . The fair values of the developed technology intangible assets were determined by using the “cost approach,” specifically the replacement cost method. The technology assets are being amortized on a straight-line basis (which approximates the economic pattern of benefits) over the estimated economic life of 3 years. The goodwill recognized represents the acquired capabilities, operating synergies and other benefits expected to result from combining the acquired operations with the Company’s existing operations. The amount of goodwill recognized from Clairvoyant’s acquisition is not deductible for tax purposes. The goodwill has been assigned to the Company’s Analytics reportable segment based upon the Company’s assessment of nature of services rendered by Clairvoyant. Acquisition-related costs are being expensed as incurred and are included in general and administrative expenses in the consolidated statements of income. The Company recognized acquisition-related costs of $134 and $761 during the three months ended and year ended March 31, 2022 and December 31, 2021, respectively. The results of operations of the acquired business and the fair value of the acquired assets and assumed liabilities are included in the Company’s consolidated financial statements with effect from the date of the acquisition. The acquisition did not materially impact the Company's financial position, results of operations or cash flows, and therefore, the Company has not provided supplemental pro forma results. Goodwill The following table sets forth details of changes in goodwill by reportable segment of the Company: Insurance Healthcare Emerging Business Analytics Total Balance at January 1, 2022 $ 50,428 $ 21,942 $ 49,020 $ 282,512 $ 403,902 Measurement period adjustments — — — 1,148 1,148 Currency translation adjustments (116) (12) (361) — (489) Balance at March 31, 2022 $ 50,312 $ 21,930 $ 48,659 $ 283,660 $ 404,561 During the fourth quarter of 2021, the Company performed its annual impairment test of goodwill for those reporting units that had goodwill recorded. Based on the results, the fair values of each of the Company’s reporting units exceeded their carrying value and the goodwill was not impaired. As of March 31, 2022, the Company evaluated the continuing effects of COVID-19 and its impact on the global economy on each of the Company’s reporting units to assess whether there was a triggering event during the quarter requiring the Company to perform a goodwill impairment test. The Company considered certain improvements in current and forecasted economic and market conditions and qualitative factors, such as the Company’s performance in the first quarter and business forecasts for the remainder of the year, stock price movements and expansion plans. The Company reviewed key assumptions, including revisions of projected future revenues for reporting units against the results of the annual impairment test performed during the fourth quarter of 2021. The Company did not identify any triggers or indications of potential impairment for its reporting units as of March 31, 2022. There can be no assurances that goodwill will not be impaired in future periods. Estimating the fair value of reporting units requires the use of estimates and significant judgments that are based on a number of factors including actual operating results. These estimates and judgements may not be within the control of the Company and accordingly it is reasonably possible that the judgments and estimates described above could change in future periods. The duration and severity of COVID-19 and continued market volatility is highly uncertain and, as such, the impact on cash flows, long-term debt-free net cash flow growth rate in the terminal year and discount rates are subject to significant judgments and may cause variability in the Company’s assessment of existence of any impairment. The Company continues to monitor the impacts of COVID-19 on the Company and significant changes in key assumptions that could result in future period impairment charges. The recoverability of goodwill is dependent upon the continued growth of cash flows from the Company’s business activities. This growth is based on business forecasts and improvement in profitability of its reporting units. The Company continues to maintain its focus on cultivating long-term client relationships as well as attracting new clients.

Derivative Financial Instruments: The Company’s derivative financial instruments consist of foreign currency forward exchange contracts. Fair values for derivative financial instruments are based on independent sources including highly rated financial institutions and are classified as Level 2. Refer to Note 16 - Derivatives and Hedge Accounting to the unaudited consolidated financial statements for further details. Fair Value of Contingent Consideration: The fair value measurement of contingent consideration is determined using Level 3 inputs. The Company’s contingent consideration represents a component of the total purchase consideration for its acquisition of Clairvoyant. The measurement is calculated using unobservable inputs based on the Company’s own assessment of achievement of certain performance goals by Clairvoyant during 2022 and 2023 calendar years. The Company estimated the fair value of the contingent consideration to be $9,000, based on Monte Carlo simulation model and scenario-based method. Financial Instruments Not Carried at Fair Value : The Company’s other financial instruments not carried at fair value consist primarily of cash and cash equivalents (except investments in money market funds, as disclosed above), short-term investments (except investments in mutual funds, as disclosed above), restricted cash, accrued interest on term deposits, accrued capital expenditures, accrued expenses and interest payable on borrowings for which fair values approximate their carrying amounts due to their short-term nature. The carrying value of the Company’s outstanding revolving credit facility approximates its fair value because the Company’s interest rate yield is near current market rates for comparable debt instruments.

Derivative Instruments and Hedging Activities Disclosure [Abstract]
Derivatives and Hedge Accounting	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 so as to minimize earnings and cash flow volatility associated with changes in foreign currency exchange rates. The Company’s derivative financial instruments are largely forward foreign exchange contracts that are designated as effective hedges and that qualify as cash flow hedges under ASC 815. The Company had outstanding cash flow hedges totaling $566,940 as of March 31, 2022 and $514,580 as of December 31, 2021. Changes in the fair value of these cash flow hedges are recorded as a component of accumulated other comprehensive income/(loss), net of tax, until the hedged transactions occurs. The resultant foreign exchange gain/(loss) upon settlement of these cash flow hedges is recorded along with the underlying hedged item in the same line of unaudited consolidated statements of income as a part of “Cost of revenues,” “General and administrative expenses,” “Selling and marketing expenses,” and “Depreciation and amortization expense,” as applicable. The Company evaluates hedge effectiveness at the time a contract is entered into as well as on an ongoing basis. 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 amounts recorded in equity are reclassified to earnings. The Company estimates that approximately $5,443 of derivative gains, net, excluding tax effects, included in AOCI, representing changes in the value of cash flow hedges, could be reclassified into earnings within the next twelve months based on exchange rates prevailing as of March 31, 2022. At March 31, 2022, the maximum outstanding term of the cash flow hedges was approximately 39 months. 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, against the risk of foreign currency fluctuations associated with remeasurement of such assets and liabilities to functional currency. These derivatives do not qualify as fair value hedges under ASC 815. Changes in the fair value of these derivatives are recognized in the unaudited consolidated statements of income and are included in the foreign exchange gain/(loss) line item. The Company’s primary exchange rate exposure is with the Indian rupee, the U.K. pound sterling (GBP) and the Philippine peso. The Company also has exposure to Colombian pesos (COP), Czech koruna, the Euro (EUR), South African ZAR, the Australian dollar (AUD) and other local currencies in which it operates. Outstanding foreign currency forward contracts amounted to USD 163,442, GBP 7,948 and EUR 1,630 as of March 31, 2022 and USD 134,612, GBP 6,763, EUR 1,343 and COP 2,541,902 as of December 31, 2021. The Company uses forward contracts designated as net investment hedges to hedge the foreign currency risks related to our investments in foreign subsidiaries. Gains and losses on these net investment hedges are recognized in AOCI as part of foreign currency translation adjustments. All of the assets and liabilities related to our foreign exchange forward contracts are subject to master netting arrangements with each individual counterparty. These master netting arrangements generally provide for net settlement of all outstanding contracts with the counterparty in the case of an event of default or a termination event. We have presented all of the assets and liabilities related to our foreign exchange forward contracts on a gross basis, with no offsets, in our unaudited consolidated statements of financial position. There is no financial collateral (including cash collateral) provided or received by us related to our foreign exchange forward contracts.

Leases [Abstract]
Leases	LeasesThe Company conducts its operations using facilities leased under operating lease agreements that expire at various dates. The Company finances its use of certain motor vehicles and other equipment under various lease arrangements provided by financial institutions. The lease agreements do not contain any covenants to impose any restrictions except for market-standard practice for similar lease arrangements. The Company had performed an evaluation of its contracts with suppliers in accordance with Topic 842, Leases , and had determined that, except for leases for office facilities, motor vehicles and other equipment as described above, none of the Company’s contracts contain a lease. In assessment of the lease term, the Company considers the extension option as part of its lease term for those lease arrangements where the Company is reasonably certain of availing the extension option. As part of the Company’s effort to moderate the impact of COVID-19, the Company continued to evaluate its office facilities to determine where it can exit, consolidate, or otherwise optimize its use of office space. The Company recognizes changes to the lease term by remeasuring lease liabilities as of the date of such modification with the resultant adjustment to the ROU assets. The impact of COVID-19 on the economic environment is uncertain and has caused variability in the determination of the incremental borrowing rate and extension option, which have an impact on measurement of lease liabilities and ROU assets.

Leases	LeasesThe Company conducts its operations using facilities leased under operating lease agreements that expire at various dates. The Company finances its use of certain motor vehicles and other equipment under various lease arrangements provided by financial institutions. The lease agreements do not contain any covenants to impose any restrictions except for market-standard practice for similar lease arrangements. The Company had performed an evaluation of its contracts with suppliers in accordance with Topic 842, Leases , and had determined that, except for leases for office facilities, motor vehicles and other equipment as described above, none of the Company’s contracts contain a lease. In assessment of the lease term, the Company considers the extension option as part of its lease term for those lease arrangements where the Company is reasonably certain of availing the extension option. As part of the Company’s effort to moderate the impact of COVID-19, the Company continued to evaluate its office facilities to determine where it can exit, consolidate, or otherwise optimize its use of office space. The Company recognizes changes to the lease term by remeasuring lease liabilities as of the date of such modification with the resultant adjustment to the ROU assets. The impact of COVID-19 on the economic environment is uncertain and has caused variability in the determination of the incremental borrowing rate and extension option, which have an impact on measurement of lease liabilities and ROU assets.

Income Tax Disclosure [Abstract]
Income Taxes	Income Taxes The Company determines the tax provision for interim periods using an estimate of its annual effective tax rate. Each quarter, the Company updates its estimate of annual effective tax rate, and if its estimated tax rate changes, the Company makes a cumulative adjustment. The impact of COVID-19 on the economic environment is uncertain and may change the annual effective tax rate, which could impact tax expense. The Company's effective tax rate increased from 21.9% during the three months ended March 31, 2021 to 23.7% during the three months ended March 31, 2022. The Company recorded income tax expense of $11,202 and $8,958 for the three months ended March 31, 2022 and 2021, respectively. The increase in the income tax expense was primarily as a result of higher profit during the three months ended March 31, 2022 compared to the three months ended March 31, 2021, and an increase in non-deductible expenses, partially offset by higher excess tax benefits during the three months ended March 31, 2022. Income tax (deferred) recognized in AOCI were as follows: Three months ended March 31, 2022 2021 Deferred taxes benefit / (expense) recognized on: Unrealized gain/(loss) on cash flow hedges $ (3) $ (398) Reclassification adjustment for cash flow hedges 515 389 Reclassification adjustment for retirement benefits (47) (51) Foreign currency translation loss 499 284 Total Income tax benefit recognized in AOCI $ 964 $ 224

As of March 31, 2022, unrecognized compensation cost of $92,797 is expected to be expensed over a weighted average period of 2.9 years. Performance Based Stock Awards Under the 2018 Plan, the Company grants performance-based restricted stock units (“PRSUs”) to executive officers and other specified employees. During the three months ended March 31, 2022, the Company granted 40% of each award recipient’s equity grants in the form of PRSUs that cliff vest at the end of a three-year period based on an aggregated revenue target for a three year period. The remaining 60% of each award recipient’s equity grants are PRSUs that are based on a market condition that is contingent on the Company's meeting the total shareholder return relative to a group of peer companies specified under the program measured over a three-year performance period. However, the features of the equity incentive compensation program are subject to change by the Compensation Committee of our Board of Directors. The award recipient may earn up to two hundred percent (200%) of the PRSUs granted based on the actual achievement of targets. Performance restricted stock unit activity under the Company’s stock plans is shown below: Revenue Based PRSUs Market Condition Based PRSUs Number Weighted-Average Number Weighted-Average Outstanding at December 31, 2021 58,864 $ 78.29 172,042 $ 113.74 Granted 52,702 119.98 79,001 155.67 Vested — — — — Forfeited — — — — Outstanding at March 31, 2022 111,566 $ 97.98 251,043 $ 126.93 As of March 31, 2022, unrecognized compensation cost of $33,048 is expected to be expensed over a weighted average period of 2.3 years. The impact of COVID-19 on the economic environment is uncertain and has caused variability in the estimation of number of performance based restricted stock units that will eventually vest and the related compensation cost to be recognized in the unaudited consolidated statements of income.

Commitments and Contingencies

Commitments and Contingencies	3 Months Ended

Commitments and Contingencies Disclosure [Abstract]
Commitments and Contingencies	Commitments and Contingencies Capital Commitments At March 31, 2022, the Company had committed to spend approximately $6,300 under agreements to purchase property and equipment. This amount is net of capital advances paid which are recognized in the unaudited consolidated balance sheets as “Capital work in progress” under “Property and equipment, net.” 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) or Special Economic Zone (SEZ) 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 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. The registration provides the Company with certain fiscal incentives on the import of capital goods and local purchase of services and materials and requires ExlService Philippines, Inc. to meet certain performance, investment and certain other criteria. The Company believes that these centers have in the past complied with the requirements. Contingencies Transfer pricing regulations generally require that any controlled intercompany transactions involving related entities be at an arm’s-length price. Accordingly, the Company determines the appropriate transfer prices for transactions among its related entities on the basis of a detailed functional and economic analysis involving benchmarking against transactions among unrelated entities. Tax authorities have jurisdiction to review transfer pricing results, and in the event that they determine that the transfer price applied was not appropriate, the Company may incur additional tax, interest and penalties. The Company is currently involved in transfer pricing disputes with Indian tax authorities regarding transactions with some of its related entities. In addition, the Company and a U.S. subsidiary are engaged in tax litigation with Indian tax authorities regarding a permanent establishment matter. The aggregate amount demanded by Indian tax authorities (net of advance payments) from the Company related to its transfer pricing and other corporate tax issues for tax years 2003 to 2019 and its permanent establishment issues for tax years 2003 to 2006 as of March 31, 2022 and December 31, 2021 is $30,711 and $34,276, respectively. The Company has made payments and/or provided bank guarantees against these demands in the amounts of $8,760 and $7,954, respectively. Amounts paid as deposits in respect of such assessments aggregating to $7,012 and $6,172 as of March 31, 2022 and December 31, 2021, respectively, are included in “Other assets” and amounts deposited for bank guarantees aggregating to $1,748 and $1,782 as of March 31, 2022 and December 31, 2021, respectively, are included in “Restricted cash” in the non-current assets section of the Company’s unaudited consolidated balance sheets. Based on the facts underlying the Company’s position and its experience with these types of assessments, the Company believes that its position will more likely than not be sustained upon final examination by the tax authorities based on its technical merits as of the reporting date and accordingly has not accrued any amount with respect to these matters in its consolidated financial statements. 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. India’s Value Added Tax ("VAT") regime ended in June 2017 and was replaced by the current Goods and Service Tax ("GST") regime. Pursuant to reviewing the Company’s annual VAT filings, the Indian tax authorities raised aggregate VAT tax demands for tax years 2015 and 2017 in an amount of $6,031 and $6,387 as of March 31, 2022 and December 31, 2021, respectively. Beginning in the first quarter of 2020, the GST authorities rejected the Company’s refunds claims in an amount of $3,259 and $3,322 as of March 31, 2022 and December 31, 2021, respectively. The Company has filed appeals against these matters and believes that it is more likely than not that upon final examination its position will be sustained based on its technical merits. Accordingly, no provision was recognized as of March 31, 2022 and December 31, 2021. In February 2019, there was a judicial pronouncement in India with respect to defined social security contribution benefits payments interpreting certain statutory defined contribution obligations of employees and employers. Currently some of the Company's subsidiaries in India are undergoing assessment with the statutory authorities. As of the reporting date, it is unclear whether the interpretation set out in the pronouncement has retrospective application. If applied retrospectively, the interpretation may result in a significant increase in contributions payable by the Company for past periods for certain of its India-based employees. There are numerous interpretative challenges concerning the retrospective application of the judgment. Due to such challenges and a lack of interpretive guidance, and based on legal advice, the Company believes it is currently impracticable to reliably estimate the timing and amount of any payments the Company may be required to make. The Company will continue to monitor and evaluate its position based on future events and developments in this matter for the implications on the financial statements, if any. In September 2020, the Indian Parliament passed various consolidating labor codes, including the Code on Social Security, 2020 (the “Indian Social Security Code”) which aims to rationalize labor laws. The Indian Social Security Code has implications on defined social security contribution plans, provision of certain benefits or facilities to employees at employer’s costs and post-retirement benefits. Most specifically, it broadens the definition of an employee and wages and liberalizes the definition of “continuous period” for the purpose of determining employee benefits, amongst others. However, the rules for the Indian Social Security Code are yet to be published and the effective date from which these changes are applicable is yet to be notified. The Company will complete its evaluation once the subject rules are notified and will give appropriate impact in the financial statements in the period in which, the Indian Social Security Code becomes effective and the related rules to determine the financial impact are published. From time to time, the Company, its subsidiaries, and/or their present officers or directors, on individual basis, may be or have been, named as a defendant in litigation matters, including employment-related claims. The plaintiffs in those cases seek damages, including, where applicable, compensatory damages, punitive damages and attorney’s fees. With respect to pending litigation matters as of the reporting date, the Company believes that the damages amounts claimed in such cases are not meaningful indicators of the potential liabilities of the Company, that these matters are without merit, and that the Company intends to vigorously defend each of them. The outcomes of legal actions are unpredictable and subject to significant uncertainties, and thus it is inherently difficult to determine the likelihood of the Company incurring a material loss or quantification of any such loss. With respect to pending litigation matters as of the reporting date, based on information currently available, including the Company’s assessment of the facts underlying each matter and advice of counsel, the amount or range of reasonably possible losses, if any, cannot be reasonably estimated. Based on the Company’s assessment, including the availability of insurance recoveries, the Company’s management does not believe that currently pending litigation, individually or in aggregate, will have a material adverse effect on the Company’s consolidated financial condition, results of operations or cash flows.

Subsequent Events [Abstract]
Subsequent Events	Subsequent Events On April 18, 2022, the Company and each of the Company’s wholly owned material domestic subsidiaries entered into the 2022 Credit Agreement, pursuant to which the parties thereto amended and restated the Credit Agreement. Among other things, the 2022 Credit Agreement (a) provides for the issuance of new revolving credit commitments such that the aggregate amount of revolving credit commitments available to the Company is equal to $400,000; (b) extends the maturity date of the Credit Facility from November 21, 2022 to April 18, 2027; and (c) replaces LIBOR with Secured Overnight Financing Rate (“SOFR”) as the reference rate for the U.S. dollar borrowings. The 2022 Credit Agreement provides an option to increase the commitments by up to $200,000, subject to certain approvals and conditions. The 2022 Credit Agreement includes a letter of credit sub facility and is voluntarily pre-payable from time to time without premium or penalty. Borrowings under the 2022 Credit Agreement can be used for working capital and general corporate purposes, including permitted acquisitions. Obligations under the 2022 Credit Agreement are guaranteed by the Company’s material domestic subsidiaries and are secured by all or substantially all of the assets of the Company and our material domestic subsidiaries. The 2022 Credit Agreement contains customary affirmative and negative covenants, including, but not limited to, restrictions on the ability to incur indebtedness, create liens, make certain investments, make certain dividends and related distributions, enter into, or undertake, certain liquidations, mergers, consolidations or acquisitions and dispose of certain assets or subsidiaries.

Summary of Significant Accoun_2

Summary of Significant Accounting Policies (Policies)	3 Months Ended
	Mar. 31, 2022
Accounting Policies [Abstract]
Basis of Preparation	Basis of Preparation and Principles of ConsolidationThe unaudited consolidated financial statements have been prepared in conformity with United States generally accepted accounting principles (“U.S. GAAP”) for interim financial information, the instructions to Form 10-Q and Article 10 of Regulation S-X. Accordingly, they do not include all of the information and footnotes required by U.S. GAAP for annual financial statements and therefore should be read in conjunction with the audited consolidated financial statements and footnotes thereto included in the Company’s Annual Report on Form 10-K for the fiscal year ended December 31, 2021.
Principles of Consolidation	The unaudited consolidated financial statements reflect all adjustments (of a normal and recurring nature) that management considers necessary for a fair presentation of such statements for the interim periods presented. The unaudited consolidated statements of income for the interim periods presented are not necessarily indicative of the results for the full year or for any subsequent period. The accompanying unaudited consolidated financial statements include the financial statements of ExlService Holdings and all of its subsidiaries. The standalone financial statements of subsidiaries are fully consolidated on a line-by-line basis. Intra-group balances and transactions, and gains and losses arising from intra-group transactions, are eliminated while preparing consolidated financial statements. Accounting policies of the respective individual subsidiary and associate are aligned wherever necessary, so as to ensure consistency with the accounting policies that are adopted by the Company under U.S. GAAP. The Company’s investments in equity affiliates are initially recorded at cost and any excess purchase consideration paid over proportionate share of the fair value of the net assets of the investee at the acquisition date is recognized as goodwill. The proportionate share of net income or loss of the investee after its acquisition is recognized in the unaudited consolidated statements of income.
Use of Estimates	Use of EstimatesThe preparation of the unaudited consolidated financial statements in conformity with U.S. 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 unaudited consolidated financial statements and the unaudited 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 unaudited consolidated financial statements include, but are not limited to, estimates of the fair value of the identifiable intangible assets and contingent consideration, purchase price allocation, including revenue projections and discount rate applied within the discounted cash flow model for business acquisitions, allowance for expected credit losses, the nature and timing of the satisfaction of performance obligations, the standalone selling price of performance obligations, and variable consideration in a customer contract, expected recoverability from customers with contingent fee arrangements, estimated costs to complete fixed price contracts, recoverability of dues from statutory authorities, assets and obligations related to employee benefit plans, deferred tax valuation allowances, income-tax uncertainties and other contingencies, valuation of derivative financial instruments, assumptions used to calculate stock-based compensation expense, assumptions used to determine the incremental borrowing rate to calculate lease liabilities and right-of-use (“ROU”) assets, lease term to calculate amortization of ROU, depreciation and amortization periods, and recoverability of long-lived assets, goodwill and intangibles.
Recent Accounting Pronouncements	Recent Accounting Pronouncements In March 2020, the Financial Accounting Standards Board (“FASB”) issued Accounting Standard Update (“ASU”) No. 2020-04, Reference Rate Reform (Topic 848): Facilitation of the Effects of Reference Rate Reform on Financial Reporting. This ASU provides optional guidance for a limited period of time to ease potential accounting impacts associated with transitioning away from reference rates that are expected to be discontinued, such as interbank offered rates and London Inter-Bank Offered Rate (“LIBOR”). The ASU provides practical expedients and exceptions for applying U.S. GAAP to contracts, hedging relationships, and other transactions affected by reference rate reform if certain criteria are met. The amendments are elective and are effective upon issuance for all entities through December 31, 2022. The Company is currently evaluating the impact of this ASU on its consolidated financial statements. In October 2021, FASB issued ASU No. 2021-08, Business Combinations (Topic 805): Accounting for Contract Assets and Contract Liabilities from Contracts with Customers . This ASU provides guidance in Topic 805 to require the acquirer entity to recognize and measure contract assets and contract liabilities acquired in a business combination in accordance with Topic 606, Revenue from Contracts with Customers , as if it had originated the contracts. Generally, this should result in an acquirer recognizing and measuring the acquired contract assets and contract liabilities consistent with how they were recognized and measured in the acquiree’s financial statements, if the acquiree prepared financial statements in accordance with U.S. GAAP. The ASU is effective for fiscal years beginning after December 15, 2022. An entity may early adopt the ASU including adoption in an interim period, with retrospective application to all business combinations within the fiscal year that includes such interim period. The Company is currently evaluating the impact of this ASU on its consolidated financial statements.
