NOTES TO UNAUDITED CONSOLIDATED FINANCIAL STATEMENTS

September 30, 2021

(In thousands, except share and per share amounts)

1. Organization

ExlService Holdings, Inc. (“ExlService Holdings”) is organized as a corporation under the laws of the state of Delaware. ExlService Holdings, together with its subsidiaries and affiliates (collectively, the “Company”), is a global analytics and digital solutions company that partners with clients to improve business outcomes and unlock growth. Bringing together deep domain expertise with robust data, powerful analytics, cloud, and AI, the Company creates agile, scalable solutions and executes complex operations for the world’s leading corporations in industries including insurance, healthcare, banking and financial services, media, and retail, among others. The Company’s clients are located principally in the United States of America (“U.S.”) and the United Kingdom (“U.K.”).

2. 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, 2020.

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, 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, purchase price allocation and recoverability of long-lived assets, goodwill and intangibles.

As of September 30, 2021, the extent to which the global Coronavirus Disease 2019 pandemic (“COVID-19”) will ultimately impact the Company's business depends on numerous dynamic factors, which the Company still cannot reliably predict. As a result, many of the Company's estimates and assumptions herein required increased judgment and carry a higher degree of variability and volatility. As events continue to evolve with respect to COVID-19, the Company’s estimates may materially change in future periods. Any changes in estimates are adjusted prospectively in the Company’s consolidated financial statements.

(c)Recent Accounting Pronouncements    

In March 2020, Financial Accounting Standard 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.

(d)Recently Adopted Accounting Pronouncements

In December 2019, FASB issued ASU No. 2019-12, Income Taxes Simplifying the Accounting for Income Taxes. This ASU eliminates certain exceptions related to the approach for intraperiod tax allocation, the methodology for calculating income taxes in an interim period and the recognition of deferred tax liabilities for outside basis differences. The Company adopted this ASU on January 1, 2021. The adoption of this ASU did not have a material impact on the Company’s unaudited consolidated financial statements.

In October 2020, FASB issued ASU No. 2020-10, Codification Improvements, to provide guidance for technical corrections such as conforming amendments, clarifications to guidance, simplifications to wording or structure of guidance, and other minor improvements. The amendments in this ASU improve the consistency of the ASC by ensuring that all guidance that requires or provides an option for an entity to provide information in the notes to financial statements is codified in the disclosure section of the ASC. The Company adopted this ASU on January 1, 2021. The adoption of this ASU did not have a material impact on the Company’s unaudited consolidated financial statements.

In January 2021, FASB issued ASU No. 2021-01, Reference Rate Reform (Topic 848): Scope, to expand the scope of Topic 848 to include derivative instruments affected by changes to the interest rates used for discounting, margining or contract price alignment (commonly referred to as the discounting transition). This ASU extends some of Topic 848’s optional expedients and exceptions for contract modifications and hedge accounting to derivative instruments impacted by discounting transition as a result of the discontinuation of the use of LIBOR as a benchmark interest rate due to reference rate reform. This ASU is effective immediately for all entities with the option to be applied retrospectively as of any date from the beginning of an interim period that includes or is subsequent to March 12, 2020, and prospectively to any new contract modifications made on or after January 7, 2021 through December 31, 2022. The adoption of this ASU did not have a material impact on the Company’s unaudited consolidated financial statements.

3. Segment and Geographical Information

The Company operates in the Business Process Management (“BPM”) industry and is a provider of operations management and analytics services.

September 30, 2021

(In thousands, except share and per share amounts)

The Company manages and reports financial information through its four strategic business units: Insurance, Healthcare, Analytics and Emerging Business. 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.

Revenues and cost of revenues for the three months ended September 30, 2021 and 2020, respectively, for each of the reportable segments, are as follows:

Accounts receivable includes $90,736 and $63,995 as of September 30, 2021 and December 31, 2020, 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. Consideration received from customers, if any, relating to such transition activities are classified under contract liabilities and are included within “Deferred revenues” and “Other non-current liabilities” in the unaudited consolidated balance sheets. The revenues are recognized as (or when) the performance obligation is fulfilled under the contract with customer.

Revenue recognized during the three and nine months ended September 30, 2021 and 2020, which was included in the contract liabilities balance at the beginning of the respective periods:

Allowance for expected credit losses

The Company evaluates the credit risk of its customers based on a combination of various financial and qualitative factors that may affect the ability of each customer to pay. The Company considered current and anticipated future economic

NOTES TO UNAUDITED CONSOLIDATED FINANCIAL STATEMENTS—(continued)

conditions relating to the industries of the Company’s customers and the countries where it operates. In calculating expected credit loss, the Company also considered past payment trends, credit rating and other related credit information for its significant customers to estimate the probability of default in the future and estimates relating to the possible effects resulting from COVID-19.

The duration and severity of COVID-19 and continued market volatility is highly uncertain and, as such, the impact on expected losses is subject to significant judgment, including but not limited to changes in customers’ credit rating, and may cause variability in the Company’s allowance for credit losses in future periods.

5. 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 assumed conversion premium of outstanding convertible notes, using the treasury stock method. Common stock equivalents and the conversion premium of outstanding convertible notes 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.

Diluted weighted-average shares outstanding is 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 intended and 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 three months ended September 30, 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. Refer to Note 17 - Borrowings to the unaudited consolidated financial statements for further details.

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

As of September 30, 2021 and December 31, 2020, 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.

9. Goodwill and Intangible Assets

Goodwill

The Company transitioned to new segment reporting structure effective January 1, 2020, which resulted in certain changes to its operating segments and reporting units. The Company reallocated goodwill to its reporting units using a relative fair value approach. In addition, the Company completed an assessment of any potential goodwill impairment for all its reporting units immediately prior to the reallocation and determined that no impairment existed.

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, 2021	$	50,499	$	21,953	$	49,348	$	227,288	$	349,088

Balance at September 30, 2021	$	50,422	$	21,942	$	49,047	$	227,288	$	348,699

During the fourth quarter of 2020, 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 September 30, 2021, 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 continued improvements in current and forecasted economic and market conditions and qualitative factors, for instance, the Company’s performance during the first three quarters, business forecasts for the remainder of the year, stock price movements and the Company’s expansion plans.

(In thousands, except share and per share amounts)

The Company did not identify any triggers or indications of potential impairment for its reporting units as of September 30, 2021.

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.

14. Accumulated Other Comprehensive Loss

Accumulated other comprehensive loss (“AOCL”) consists of actuarial gain/(loss) on retirement benefits and foreign currency translation adjustments. In addition, the Company enters into foreign currency exchange contracts, which are designated as cash flow hedges and net investment hedges in accordance with ASC 815. Cumulative changes in the fair values of these foreign currency exchange contracts are recognized in AOCL on the Company's unaudited consolidated balance sheets. Upon settlement of foreign exchange contracts designated as cash flow hedges, fair value changes are reclassified from AOCL to net income, whereas such fair value changes related to net investment hedges are included in net income when a foreign operation is disposed or partially disposed. The balances as of September 30, 2021 and 2020 are as follows:

* Represents those short-term investments, which are carried at the fair value option under ASC 825 "Financial Instruments.”

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.

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, 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.

Convertible Senior Notes:

The Company settled the Notes during the three months ended September 30, 2021. Refer to Note 17 - Borrowings to the unaudited consolidated financial statements for further details.

The total estimated fair value of the Notes as of December 31, 2020 was $152,384. The fair value was determined based on market yields for similar convertible notes as of December 31, 2020. The Company considers the fair value of the Notes to be a Level 2 measurement due to the limited inputs available for its fair valuation.

16. 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 $515,850 as of September 30, 2021 and $451,935 as of December 31, 2020.

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,” “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 $5,695 of derivative gains, net, excluding tax effects, included in AOCL, 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 September 30, 2021. At September 30, 2021, the maximum outstanding term of the cash flow hedges was 45 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 140,119, GBP 5,911, EUR 1,005 and COP 4,675,248 as of September 30, 2021 and USD 143,394, GBP 6,753, EUR 2,447 and COP 8,287,950 as of December 31, 2020.

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 AOCL 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.

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

Credit Agreement

The Company’s $300,000 revolving credit facility pursuant to its credit agreement (the “Credit Agreement”) with certain lenders and Citibank N.A. as Administrative Agent (the “Credit Facility”) carried an effective interest rate as shown below.

	Three months ended September 30,				Nine months ended September 30,

As of September 30, 2021 and December 31, 2020, the Company was in compliance with all financial and non-financial covenants listed under the Credit Agreement.

Convertible Senior Notes

On October 1, 2018, the Company entered into an investment agreement (the “Investment Agreement”) with Orogen Echo LLC (the “Purchaser”), an affiliate of The Orogen Group LLC, relating to the issuance to the Purchaser of $150,000, in an aggregate principal amount of the Notes. The transactions contemplated by the Investment Agreement, including the issuance of the Notes, closed on October 4, 2018. The Notes carried interest at a rate of 3.5% per annum, payable semi-annually in arrears in cash on April 1 and October 1 of each year. The Notes were convertible at an initial conversion rate of 13.3333 shares of the common stock per one thousand dollar principal amount of the Notes (which represented an initial conversion price of approximately $75 per share). The Company had the option to redeem the principal amount of the Notes, at its option, in whole but not in part, at a purchase price equal to the principal amount plus accrued and unpaid interest on or after October 1, 2021, if the closing sale price of the common stock exceeded 150% of the then-current conversion price for 20 or more trading days in the 30 consecutive trading day period preceding the Company’s exercise of this redemption right (including the trading day immediately prior to the date of the notice of redemption). The Company had the option to elect to settle conversions of the Notes by paying or delivering, as the case may be, cash, shares of the Company’s common stock or a combination of cash and shares of the Company’s common stock.

The Notes carried an effective interest rate as shown below:

Effective Interest Rate	3.6	%	3.6	%	3.6	%	3.6	%

On August 27, 2021, the Company entered into a Payoff and Termination Agreement (the “Payoff and Termination Agreement”) with the Purchaser, pursuant to which the Company prepaid and settled its outstanding obligations under the Notes for an aggregate consideration of $236,742, excluding accrued and unpaid interest under the Notes calculated through, and including, August 26, 2021, in the form of a combination of cash and shares of the Company’s common stock. As a result, the Company made a cash payment of $200,000 to the Purchaser and satisfied the remainder of the obligation under the Notes by issuing to the Purchaser 310,394 shares of the Company’s common stock calculated at $118.37 per share based on a 20-day volume weighted average price ending on, and including, August 26, 2021. The Company satisfied the cash payment obligation under the Payoff and Termination Agreement by drawing $200,000 from its existing revolving Credit Facility, and the Company’s common stock was issued from its existing treasury shares. Refer to Note 18 - Capital Structure to the unaudited consolidated financial statements for further details.

The aggregate consideration of $236,742 was allocated between the debt and equity components in an amount of $152,742 and $84,000, respectively. The consideration was first allocated to the fair value of debt component and the remaining was allocated to the equity component. The fair value of the debt component was calculated using a discounted cash flow technique, which considered debt issuances with similar features of the Company’s debt, without the conversion feature. The resulting effective interest rate for the Notes was 2.9% per annum at the time of settlement. The portion allocated to the equity component was recorded as additional paid-in capital.

Immediately prior to the settlement of the Notes, the carrying amount of the debt component of the Notes, net of unamortized debt discount and issuance costs, was $139,897. During the three months ended September 30, 2021, the Company recognized a loss on settlement of the Notes of $12,845, representing the difference between the fair value of the consideration allocated to the debt component and the carrying value of the debt component immediately before settlement, and is presented as “Loss on settlement of convertible notes,” in the Company’s unaudited consolidated statements of income.

During the three and nine months ended September 30, 2021 and 2020, the Company recognized interest expense and amortization of debt discount, on the Notes as below:

	Three months ended September 30,				Nine months ended September 30,
	2021		2020		2021		2020
Interest expense on the Notes	$	817	$	1,313	$	3,442	$	3,938
Amortization of debt discount on the Notes	$	431	$	654	$	1,795	$	1,943

Expected payments for all of the Company's borrowings as of September 30, 2021 were as follows:

Nine months ended September 30, 2020	26,601	$	2,012	$	75.63

On December 16, 2019, the Company’s Board of Directors authorized a $200,000 common stock repurchase program beginning January 1, 2020 through December 31, 2022 (the "2019 Repurchase Program"). Under the 2019 Repurchase Program, shares may be purchased by the Company from time to time from the open market and through private transactions, or otherwise, as determined by the Company’s management as market conditions warrant. Repurchases may be discontinued at any time by the management.

The Company purchased shares of its common stock, including commissions, under the 2019 Repurchase Program, as below:

	Shares repurchased	Total consideration		Weighted average purchase price per share (1)
Three months ended September 30, 2021	244,580	$	28,196	$	115.28

(1) The weighted average purchase price per share was the closing 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.

Repurchased shares have been recorded as treasury shares and will be held until the Company’s Board of Directors designates that these shares be retired or used for other purposes.

The 2019 Repurchase Program may be suspended or discontinued at any time.

In connection with the settlement of the Notes, the Company issued to the Purchaser 310,394 shares of the Company's common stock. This common stock was issued from the Company’s existing treasury shares. The excess of issuance price of the Company’s treasury stock over its weighted average cost was recognized in additional paid-in-capital.

(In thousands, except share and per share amounts)

The Company’s Gratuity Plan in India (the "India Plan") provides for a 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. In addition, the Company’s subsidiary operating in the Philippines conforms to the minimum regulatory benefit, which provide for lump sum payment to vested employees on retirement from employment in an amount based on the respective employee’s salary and years of employment with the Company (the "Philippines Plan"). Liabilities with regard to the India Plan and the Philippines Plan are determined by actuarial valuation using the projected unit credit method. Current service costs for these Plans 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.

Components of net periodic benefit costs, were as follows:

	Three months ended September 30,				Nine months ended September 30,
	2021		2020		2021		2020
Service cost	$	874	$	679	$	2,648	$	2,021
Interest cost	231		242		700		722
Expected return on plan assets	(199)		(159)		(600)		(477)
Amortization of actuarial loss, gross of tax	178		98		533		296
Net gratuity cost	$	1,084	$	860	$	3,281	$	2,562
Income tax benefit on amortization of actuarial loss	(32)		(32)		(154)		(96)
Amortization of actuarial loss, net of tax	$	146	$	66	$	379	$	200

    

The India Plan is partially funded whereas the Philippines plan is unfunded. The Company makes annual contributions to the employees' gratuity fund of the India Plan established with Life Insurance Corporation of India and HDFC Standard Life Insurance Company. Fund managers manage these funds and calculate the annual contribution required to be made by the Company and manage the India Plan, including any required payouts. These funds are managed on a cash accumulation basis and interest is declared retrospectively on March 31 of each year. The Company expects to earn a return of approximately 6.8% per annum on the India Plan for the year ended December 31, 2021.

The Company maintains several 401(k) plans (the “401(k) Plans”) under Section 401(k) of the Internal Revenue Code of 1986, as amended (the “Code”), covering all eligible employees, as defined in the Code as a defined contribution plan. The Company may make discretionary contributions of up to a maximum of 4.0% of employee compensation within certain limits.

The Company's accrual for contributions to the 401(k) Plans were as follows:

20. Leases

The 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. During the nine months ended September 30, 2021 and year ended December 31, 2020, the Company changed the lease term for certain of its leases and recognized the resultant amount of the remeasurement of the lease liability as an 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.

21. 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 decreased from 24.3% during the three months ended September 30, 2020 to 13.7% during the three months ended September 30, 2021. The Company recorded income tax expense of $4,196 and $8,490 for the three months ended September 30, 2021 and 2020, respectively. The decrease in income tax expense was primarily a result of (i) the recording of a one-time deferred tax benefit of $2,400 on settlement of the Notes during the three months ended September 30, 2021, (ii) the recording of excess tax benefits related to stock awards of $528 pursuant to ASU No. 2016-09 during the three months ended September 30, 2021, and (iii) lower profit during the three months ended September 30, 2021, compared to the three months ended September 30, 2020.

The Company's effective tax rate decreased from 24.3% during the nine months ended September 30, 2020 to 20.3% during the nine months ended September 30, 2021. The Company recorded income tax expense of $22,019 and $18,416 for the nine months ended September 30, 2021 and 2020, respectively. The increase in the income tax expense was primarily a result of higher profit during the nine months ended September 30, 2021, compared to the nine months ended September 30, 2020, and the recording of higher excess tax benefits related to stock awards of $1,874 pursuant to ASU No. 2016-09 during the nine months ended September 30, 2020, compared to $1,556 during the nine months ended September 30, 2021, partially offset by (i) the recording of a one-time deferred tax benefit of $2,400 on settlement of the Notes during the nine months ended September 30, 2021, and (ii) the recording of a one-time tax expense of $1,320 due to election of a new tax regime, during the nine months ended September 30, 2020, for two of the Company's Indian subsidiaries that provides for a lower tax rate on earnings in exchange for foregoing certain tax credits, including minimum alternative tax credits.

During the three months ended September 30, 2021, the Company repatriated to the United States $17,000 (net of $908 withholding taxes) from India. During the nine months ended September 30, 2021, the Company repatriated to the United States $66,000 (net of $3,494 withholding taxes) from India and $42,500 (net of $7,494 withholding taxes) from the Philippines. As of September 30, 2021, the Company accrued withholding taxes of $10,988 associated with these distributions and increased the Company’s deferred tax assets. These distributions do not constitute a change in the Company’s permanent reinvestment assertion. The Company bases its decision to continue to indefinitely reinvest earnings in India and the Philippines on its estimate of the working capital required to support its operations in these geographies and periodically reviews its capital initiatives to support and expand the Company’s global operations, as well as an economically viable rate of return on its investments made in India and the Philippines as compared to those made in the United States.

Income tax (deferred) recognized in “Other comprehensive income / (loss)” were as follows:

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 nine months ended September 30, 2021, the Company granted PRSUs that cliff vest at the end of a three year period 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. 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:

As of September 30, 2021, unrecognized compensation cost of $15,264 is expected to be expensed over a weighted average period of 1.9 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.

24. Commitments and Contingencies

Capital Commitments

At September 30, 2021, the Company had committed to spend approximately $5,200 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 or Special Economic Zone 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 and investment criteria. The Company believes that these centers have in the past satisfied and will continue to satisfy the required criteria.

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 entities that are unrelated. 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. Further, the Company and a U.S. subsidiary are engaged in tax litigation with Indian tax authorities regarding a permanent establishment matter. For the United States, the Philippines and India, tax year 2016 and subsequent tax years remain open for examination by the tax authorities as of September 30, 2021.

The aggregate amount demanded by Indian tax authorities (net of advance payments, if any) 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 September 30, 2021 and December 31, 2020 is $34,399 and $16,748, respectively. The Company has made payments and/or provided bank guarantees against these demands in the amounts of $8,014 and $8,120, respectively. Amounts paid as deposits in respect of such assessments aggregating to $6,229 and $6,307 as of September 30, 2021 and December 31, 2020, respectively, are included in “Other assets” and amounts deposited for bank guarantees aggregating to $1,785 and $1,813

as of September 30, 2021 and December 31, 2020, respectively, are included in “Restricted cash” in the non-current assets section of the Company’s unaudited and audited consolidated balance sheets, respectively.

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 unaudited 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.

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.

•adverse outcome of our disputes with the Indian tax authorities.

These and other factors are more fully discussed in our Annual Report on Form 10-K for the fiscal year ended December 31, 2020. These and other risks could cause actual results to differ materially from those implied by forward-looking statements in this Quarterly Report on Form 10-Q.

The forward-looking statements made by us in this Quarterly Report on Form 10-Q, or elsewhere, speak only as of the date on which they were made. New risks and uncertainties come up from time to time, and it is impossible for us to predict those events or how they may affect us. We have no obligation to update any forward-looking statements in this Quarterly Report on Form 10-Q after the date of this Quarterly Report on Form 10-Q, except as required by federal securities laws.

Executive Overview

We are a leading global analytics and digital solutions company that helps our clients build and grow sustainable businesses. By bringing together our deep domain expertise with robust data, powerful analytics, cloud, and AI, we create agile, scalable solutions and execute complex operations for the world’s leading corporations in industries including insurance, healthcare, banking and financial services, media, and retail, among others.

We operate in the Business Process Management (“BPM”) industry and we provide operations management and analytics services. We manage and report financial information through our four strategic business units: Insurance, Healthcare, Analytics and Emerging Business.

Our global delivery network, which includes highly trained industry and process specialists across the United States, Latin America, South Africa, Europe and Asia (primarily India and the Philippines), is a key asset. We have operations centers in India, the United States, the United Kingdom, the Philippines, Bulgaria, Colombia, South Africa, Romania and the Czech Republic.

Continued impact of COVID-19 on Our Business

The global COVID-19 pandemic continues to materially impact worldwide economic activity and levels of business confidence and has had widespread, rapidly-evolving and unpredictable impacts on global societies, economies, financial markets and business practices. During 2020, COVID-19 materially impacted our business, however during the first nine months of 2021, we saw improvement in key indicators, despite being prevented from conducting business activities as usual from geographies affected by new variants of the COVID-19 virus. Over the course of 2020, and continuing into 2021, our customers, contractors, suppliers, and other partners adapted in order to conduct business activities in a COVID-19 environment. The U.S. economy continued on a path to recovery in the first nine months of 2021 with millions of Americans receiving the COVID-19 vaccine, and states and municipalities increasingly reopening. In addition, the U.S. federal government continued to enact policies to provide fiscal stimulus to the economy and relief to those affected by the pandemic. As the global economy begins to emerge from the impact of COVID-19 in 2021, our clients are focused on receiving personalized customer experiences, optimizing costs and supporting resilient operating models. We remain committed to helping our clients adapt and

42

thrive through the ongoing uncertainties caused by COVID-19 and, going forward, to the shifting business environment. Notwithstanding the recent improvement in conditions during the first nine months of 2021, the COVID-19 pandemic continues, with temporary shutdowns at our operations centers requested or mandated by governmental authorities, and due to the associated uncertainties, we continue to evaluate the nature and scope of the impact to our business and may take further strategic actions in order to manage our business operations, costs and liquidity in response to the ongoing impacts and changing conditions and markets resulting from COVID-19.

We have a business continuity plan in place and have, since early in the pandemic, adapted delivery to a work from home model, while actively working to understand our clients’ changing requirements, continuing to ensure data security, prioritizing critical processes, adjusting service levels and managing discretionary costs (such as travel costs) and fixed costs (such as non-critical personnel costs). We have made ongoing efforts to reduce our reliance on travel by incorporating into our business model the ability to conduct business using virtual conferencing and collaboration tools to enable our employees to stay connected with each other, and our sales, marketing and support teams to continue to engage with and remain responsive to our clients. Our work from home delivery capability steadily improved throughout 2020 and continued to improve during the first nine months of 2021. We estimate that we are able to deliver a significant portion of our clients’ current requirements in a work from home model given the current lockdown restrictions in the locations in which we operate and certain clients not authorizing us to perform the remaining process work remotely due to its sensitive nature. In addition, we have also worked, and continue to work with national, state, and local authorities to comply with applicable rules and regulations related to COVID-19. There continues to be volatility and economic and geopolitical uncertainty in many markets around the world due to the emergence and spread of new variants of COVID-19 across geographies. Despite the efforts described above, there is a risk that if jurisdictions in which we operate reinstate prior restrictions, stagnate in their reopening processes, or implement new restrictions in response to new outbreaks or continued spread, our operations and business could be materially impacted. In late March 2021, a new serious outbreak of the COVID-19 virus began affecting India with an exorbitant spike in the number of COVID patients. The Indian government reinstated lockdowns limiting in certain cases the movement of our employees to offices, however these lockdowns were lifted as the situation in India improved. During the same period, the Philippines also began experiencing a spike in the number of COVID patients. In July 2021, we saw a significant increase in number of COVID-19 cases across the U.S. brought on by the new variant of the COVID-19 virus. Our Indian, Philippines and U.S. operations were not materially affected as we initiated appropriate business continuity procedures, so as to minimize the effects of these new developments, but it is possible that our business and results of operations could nevertheless be materially affected if any further developments, including new variants of the COVID-19 virus, emerge.

We also took actions in response to the pandemic that focused on helping our employees. In the geographies most affected by the recent COVID-19 variants, these actions included healthcare support including securing and administering vaccines for our employees, facilitating our employees’ access to medical equipment, providing ambulance services and online medical consultations, extending medical insurance to our employees’ family members and enhancing the dollar value of such coverage. We also instituted a one-time employee compensation payment to beneficiaries of employees, facilitated voluntary contributions from our clients and employees to support the family members of deceased employees and providing financial support for their children's education. Other actions included disseminating guidance and information to our employees, facilitating work from home, implementing best practices for employees while working from home, periodic CEO messaging, various programs aimed at employee wellness, including a global wellness program, enhanced leave for employees affected by COVID-19, enhanced awareness towards information security, and updated cyber security and data privacy policies, among others. We continue to have broad travel restrictions, and while we expect some level of travel to return, we do not expect it to be at pre-pandemic levels. We are largely operating in virtual-only events for the safety of our employees and our customers with some expectations of return to office for selected employees, as and when necessary. We also implemented pandemic-specific protocols for our essential employees whose jobs require them to be on-site or with our customers by implementing additional safety measures at all of our facilities, including increased frequency in cleaning and disinfecting, and enhanced hygiene and social distancing practices.

We continue to incur additional costs in order to ensure the continuity of our operations and support our work from home model. Such costs include purchase of desktops and laptops for our employees, software and internet connectivity devices, technology tools for productivity enhancement, accommodation, meal, overtime, transportation and regular sanitization and cleaning costs of our offices and facilities. We also expect that we will continue to incur additional costs to monitor and improve operational efficiency of our work from home model, implement new information technology solutions and security measures to safeguard against information security risks and protect the health and safety of our employees as they gradually return to the office. We believe that these short-to-medium-term costs may benefit us in the long-term, as these steps have broadened our “remote working” capabilities, which we expect to become a permanent feature in our future delivery model, as well as our business continuity plans.

43

In response to certain anticipated impacts from COVID-19, we implemented a series of temporary cost reduction measures in 2020 which continued in the first nine months of 2021 to further preserve financial flexibility. These actions included the postponement of certain discretionary spending including travel and marketing expenses, reevaluating the pace of our capital expenditures, rationalizing certain of our real estate and facilities, deferring non-critical hiring among others.

Certain impacts of COVID-19 on our business, results of operations, financial position and cash flow during the first nine months of 2021 has been described above and below, however the full extent of the impact for the period beyond the first nine months of 2021 is currently uncertain and will depend on many factors that are not within our control, including, but not limited to: the duration and scope of the pandemic; the effectiveness of actions taken to contain or mitigate the pandemic, prevent or limit any reoccurrence and emergence of new variants of the virus; governmental, business and individuals’ actions that have been and continue to be taken in response to the pandemic; development and availability of effective treatments and vaccines, the speed at which such vaccines are administered, the extent of vaccine aversion, as well as the effect of emerging targeted vaccine mandates and booster vaccines, and breakthrough infections among the fully vaccinated; significant increases in healthcare costs in the event that a significant number of our personnel become infected with COVID-19 and require medical treatment; general economic uncertainty in key global markets and financial market volatility; global economic conditions and levels of economic growth; and the pace of recovery when COVID-19 subsides. Due to the above circumstances and as described generally in this Quarterly Report on Form 10-Q, our financial results, including but not limited to net revenues, income from operations, net income, cash flow and earnings per share, are not necessarily indicative of the results to be expected for the full fiscal year of 2021. We continue to monitor the implications of COVID-19 on our business, as well as our customers’ and suppliers’ businesses.

For additional information and risks related to COVID-19, see Item 1A - “Risk Factors” included elsewhere in this Quarterly Report on Form 10-Q and Part I, Item 1A, “Risk Factors” in our Annual Report on Form 10-K for the fiscal year ended December 31, 2020.

Revenues

For the three months ended September 30, 2021, we had revenues of $290.3 million compared to revenues of $241.0 million for the three months ended September 30, 2020, an increase of $49.3 million, or 20.5%. For the nine months ended September 30, 2021, we had revenues of $826.8 million compared to revenues of $709.5 million for the nine months ended September 30, 2020, an increase of $117.3 million, or 16.5%.

We serve clients mainly in the United States and the United Kingdom, with these two regions generating 86.0% and 9.4%, respectively, of our total revenues for the three months ended September 30, 2021, and 84.6% and 9.5%, respectively, of our total revenues for the three months ended September 30, 2020. For the nine months ended September 30, 2021, these two regions generated 85.8% and 9.5%, respectively, of our total revenues and 84.7% and 9.2%, respectively, of our total revenues for the nine months ended September 30, 2020.

For the three months ended September 30, 2021 and 2020, our total revenues from our top ten clients accounted for 38.7% each of our total revenues. For the nine months ended September 30, 2021 and 2020, our total revenues from our top ten clients accounted for 38.6% and 37.3% of our total revenues, respectively. Our revenue concentration with our top clients remains largely consistent year-over-year and we continue to develop relationships with new clients to diversify our client base. We believe that the loss of any of our top ten clients could have a material adverse effect on our financial performance.

Our Business

We provide operations management and analytics services. We market our services to our existing and prospective clients through our sales and client management teams, which are aligned by key industry verticals and cross-industry domains such as finance and accounting. Our sales and client management teams operate from the United States, Europe and Australia.

Operations Management Services: We provide our clients with a range of operations management services from our Insurance, Healthcare and Emerging Business operating segments, which typically involve the transfer by our clients to EXL of certain of their business operations, such as claims processing, clinical operations, or financial transaction processing, after which we administer and manage those operations on an ongoing basis. As part of this transfer, we hire and train employees to

44

work at our operations centers on the relevant business operations, implement a process migration to these operations centers and then provide services either to the client or directly to the client’s customers. Each client contract has different terms based on the scope, deliverables and complexity of the engagement. We also provide consulting services related to operations management that include industry-specific digital transformational services as well as cross-industry finance and accounting services as part of the Emerging Business operating segment.

We provide our services under contracts with our clients, which typically have terms of three or more years, with some being rolling contracts with no end dates. Typically, our clients can terminate these contracts with or without cause and with short notice periods. These contracts provide us with a relatively predictable revenue base for a substantial portion of our operations management business. However, we have a long selling cycle for our services and the budget and approval processes of prospective clients make it difficult to predict the timing of entering into definitive agreements with new clients. Similarly, new license sales and implementation projects for our technology service platforms and other software-based services have a long selling cycle, however ongoing annual maintenance and support contracts for existing arrangements provide us with a relatively predictable revenue base.

We charge for our services using various pricing models like time-and-material pricing, full-time-equivalent pricing, transaction-based pricing, outcome-based pricing, subscription-based pricing and other alternative pricing models. Outcome-based pricing arrangements are examples of non-linear pricing models where clients link revenues from platforms and solutions and the services we provide to usage or savings rather than the efforts deployed to provide these services. We continue to observe a shift in the industry pricing models toward transaction-based pricing, outcome-based pricing and other alternative pricing models. We believe this trend will continue and we use such alternative pricing models with some of our current clients and are seeking to move certain other clients from a full-time-equivalent pricing model to a transaction-based or other alternative pricing model. These alternative pricing models place the focus on operating efficiency in order to maintain or improve our gross margins.

We have also observed that prospective larger clients are entering into multi-vendor relationships with regard to their outsourcing needs. We believe that the trend toward multi-vendor relationships will continue. A multi-vendor relationship allows a client to seek more favorable pricing and other contract terms from each vendor, which can result in significantly reduced gross margins from the provision of services to such client for each vendor. To the extent our large clients expand their use of multi-vendor relationships and are able to extract more favorable contract terms from other vendors, our gross margins and revenues may be reduced with regard to such clients if we are required to modify the terms of our relationships with such clients to meet competition.

Analytics: Our analytics services focus on driving improved business outcomes for our customers by unlocking deep insights from data and create data-driven solutions across all parts of our customers’ business. We also provide care optimization and reimbursement optimization services, for our clients through our healthcare analytics solutions and services. We also offer integrated solutions to help our clients in cost containment by leveraging technology platforms, customizable and configurable analytics and expertise in healthcare reimbursements to help clients enhance their claim payment accuracy. Our teams deliver predictive and prescriptive analytics in the areas of customer acquisition and lifecycle management, risk underwriting and pricing, operational effectiveness, credit and operational risk monitoring and governance, regulatory reporting, payment integrity and care management and data management. We enhance, modernize and enrich structured and unstructured data and use a spectrum of advanced analytical tools and techniques, including our in-house Machine Learning (“ML”) and Artificial Intelligence (“AI”) capabilities to create insights and improve decision making for our clients. We actively cross-sell and, where appropriate, integrate our Analytics services with other operations management services as part of a comprehensive offering for our clients. Our projects-based analytics services are cyclical and can be significantly affected by variations in business cycles. In addition, our projects-based analytics services are documented in contracts with terms generally not exceeding one year and may not produce ongoing or recurring business for us once the project is completed. These contracts also usually contain provisions permitting termination of the contract after a short notice period. The short-term nature and specificity of these projects could lead to fluctuations and uncertainties in the revenues generated from providing analytics services.

We anticipate that revenues from our analytics services will grow as we expand our service offerings and client base, both organically and through acquisitions.

Revenues.

The following table summarizes our revenues by reportable segments for the three months ended September 30, 2021 and 2020:

	Three months ended September 30,						Percentage change
	2021		2020		Change
	(dollars in millions)
Insurance	$	98.0	$	87.8	$	10.2	11.6	%

Emerging Business	44.5		37.6		6.9		18.5	%
Analytics	120.5		90.5		30.0		33.1	%
Total revenues, net	$	290.3	$	241.0	$	49.3	20.5	%

Revenues for the three months ended September 30, 2021 were $290.3 million, up $49.3 million, or 20.5%, compared to the three months ended September 30, 2020.

Revenue growth in Insurance of $10.2 million was primarily driven by expansion of business from our existing clients aggregating to $9.9 million and an increase in revenues of $0.3 million that was mainly attributable to the appreciation of the U.K. pound sterling against the U.S. dollar during the three months ended September 30, 2021, compared to the three months ended September 30, 2020. Insurance revenues were 33.8% and 36.4% of our total revenues in the three months ended September 30, 2021 and September 30, 2020, respectively.

Revenue growth in Healthcare of $2.2 million was primarily driven by expansion of business from our new clients aggregating to $2.2 million during the three months ended September 30, 2021. Healthcare revenues were 9.4% and 10.4% of our total revenues in the three months ended September 30, 2021 and September 30, 2020, respectively.

Revenue growth in Emerging Business of $6.9 million was primarily driven by expansion of business from our new and existing clients aggregating to $6.8 million and an increase in revenues of $0.1 million that was mainly attributable to the appreciation of the U.K. pound sterling against the U.S. dollar during the three months ended September 30, 2021, compared to the three months ended September 30, 2020. Emerging Business revenues were 15.3% and 15.6% of our total revenues in the three months ended September 30, 2021 and September 30, 2020, respectively.

Revenue growth in Analytics of $30.0 million was attributable to the higher volumes in our annuity and project-based engagements from our new and existing clients of $29.6 million and an increase in revenues of $0.4 million mainly attributable to the appreciation of the U.K. pound sterling and the South African ZAR against the U.S. dollar during the three months ended September 30, 2021, compared to the three months ended September 30, 2020. Analytics revenues were 41.5% and 37.5% of our total revenues in the three months ended September 30, 2021 and September 30, 2020, respectively.

Cost of Revenues and Gross Margin: The following table sets forth cost of revenues and gross margin of our reportable segments.

	Cost of Revenues								Gross Margin
	Three months ended September 30,				Change		Percentage change		Three months ended September 30,				Change
	2021		2020						2021		2020
	(dollars in millions)
Insurance	$	61.4	$	56.8	$	4.6	8.1	%	37.3	%	35.3	%	2.0	%
Healthcare	17.1		18.0		(0.9)		(5.0)	%	37.6	%	28.4	%	9.2	%

Analytics	75.5		56.5		19.0		33.6	%	37.3	%	37.6	%	(0.3)	%
Total	$	177.7	$	152.1	$	25.6	16.8	%	38.8	%	36.9	%	1.9	%

For the three months ended September 30, 2021, cost of revenues was $177.7 million compared to $152.1 million for the three months ended September 30, 2020, an increase of $25.6 million, or 16.8%. Our gross margin for the three months ended September 30, 2021 was 38.8% compared to 36.9% for the three months ended September 30, 2020, an increase of 190 basis points ("bps") primarily driven by higher revenues and operational efficiencies during the three months ended September 30, 2021, compared to three months ended September 30, 2020.

The increase in cost of revenues in Insurance of $4.6 million for the three months ended September 30, 2021 was primarily due to increases in employee-related costs of $6.0 million, partially offset by lower travel costs of $1.3 million and foreign exchange gain, net of hedging $0.1 million. Gross margin in Insurance increased by 200 bps during the three months ended September 30, 2021, compared to the three months ended September 30, 2020, primarily due to operational efficiencies during the three months ended September 30, 2021, compared to the three months ended September 30, 2020.

The decrease in cost of revenues in Healthcare of $0.9 million for the three months ended September 30, 2021 was primarily due to decreases in employee-related costs of $0.5 million and lower technology costs of $0.4 million. Gross margin in Healthcare increased by 920 bps during the three months ended September 30, 2021, compared to the three months ended September 30, 2020, primarily due to higher revenues and operational efficiencies during the three months ended September 30, 2021, compared to the three months ended September 30, 2020.

The increase in cost of revenues in Emerging Business of $2.9 million for the three months ended September 30, 2021 was primarily due to increases in employee-related costs of $2.5 million and higher technology costs of $0.4 million.

As of September 30, 2021 and 2020, we had $284.3 million and $362.6 million, respectively, in cash, cash equivalents and short-term investments, of which $254.2 million and $300.7 million, respectively, is located in foreign jurisdictions that upon distribution may be subject to withholding and other taxes. We periodically evaluate opportunities to distribute cash among our group entities to fund our operations in the United States and other geographies, and as and when we decide to distribute, we may have to accrue, additional taxes in accordance with local tax laws, rules and regulations in the relevant foreign jurisdictions. During the three months ended September 30, 2021, we repatriated to the United States $17.0 million (net of $0.9 million withholding taxes) from India. During the nine months ended September 30, 2021, we repatriated to the United States $66.0 million (net of $3.5 million withholding taxes) from India and $42.5 million (net of $7.5 million withholding taxes) from the Philippines. These distributions do not constitute a change in our permanent reinvestment assertion. We base our decision to continue to indefinitely reinvest earnings in India and the Philippines on our estimate of the working capital required to support our operations in these geographies and periodically review our capital initiatives to support and expand our global operations, as well as an economically viable rate of return on our investments made in India and the Philippines as compared to those made in the United States.

Operating Activities: Net cash provided by operating activities was $113.8 million for the nine months ended September 30, 2021 as compared to net cash provided by operating activities of $126.3 million for the nine months ended September 30, 2020, reflecting higher working capital needs, offset by higher cash earnings. The major drivers contributing to the decrease of $12.5 million year-over-year included the following:

•Changes in accounts receivable, including advance billings, contributed lower cash flow of $78.4 million in the nine months ended September 30, 2021 compared to the nine months ended September 30, 2020. The decrease was a result of higher accounts receivable resulting from revenue growth, change in credit terms for certain clients during the nine months ended September 30, 2021, and advance collections during the three months ended December 31, 2020. Lower cash flows were also affected by our accounts receivable days sales outstanding, which marginally increased to 58 days as of September 30, 2021 from 57 days as of September 30, 2020.

•Increase in net income of $29.1 million in the nine months ended September 30, 2021 compared to the nine months ended September 30, 2020, primarily due to an increase in income from operations of $48.0 million driven by higher revenues, lower interest expense of $1.8 million, partially offset by loss on settlement of the Notes of $12.8 million, lower other income, net of $3.9 million, and higher income tax expense of $3.7 million.

•Increase in accrued employee costs, accrued expenses and other liabilities contributed higher cash flow of $56.3 million in the nine months ended September 30, 2021 compared to the nine months ended September 30, 2020. The increase was primarily due to lower payment and higher provisions of annual performance incentives of $37.2 million, higher other employee cost accruals of $2.5 million and higher accrued expenses and other liabilities of $16.6 million, during the nine months ended September 30, 2021 compared to the nine months ended September 30, 2020.

•Other drivers decreasing cash flows during the nine months ended September 30, 2021 compared to the nine months ended September 30, 2020 included: income tax payments, net of refunds, of $19.6 million, primarily due to higher advance income tax payments on higher net income.

55

Investing Activities: Cash flows used for investing activities were $21.5 million for the nine months ended September 30, 2021 as compared to cash flows provided by investing activities of $11.1 million for the nine months ended September 30, 2020. The decrease is mainly due to net redemption of investments of $6.7 million during nine months ended September 30, 2021 as compared to net redemption of investments of $45.8 million during the nine months ended September 30, 2020. This was partially offset by lower capital expenditures for purchase of long-lived assets, including investments in infrastructure, technology assets, software and product developments of $5.8 million during the nine months ended September 30, 2021 as compared to the nine months ended September 30, 2020 and acquisition of an additional stake in our equity affiliate of $0.7 million during the nine months ended September 30, 2020.

Financing Activities: Cash flows used for financing activities were $189.1 million during the nine months ended September 30, 2021 as compared to cash flows used for financing activities of $48.4 million during the nine months ended September 30, 2020. The increase in cash flows used for financing activities was primarily due to higher net repayment of our borrowings of $94.0 million under our revolving Credit Facility and the Notes and higher purchases of treasury stock by $46.7 million under our share repurchase program during the nine months ended September 30, 2021 as compared to the nine months ended September 30, 2020.

We expect to use cash from operating activities to maintain and expand our business by making investments primarily related to new facilities and capital expenditures associated with leasehold improvements to build our facilities, digital capabilities and purchase telecommunications equipment and computer hardware and software in connection with managing client operations.

We incurred $29.0 million of capital expenditures in the nine months ended September 30, 2021. We expect to incur capital expenditures of between $35.0 million and $40.0 million in 2021, primarily to meet our growth requirements, including additions to our facilities as well as investments in technology applications, product development, digital technology, advanced automation, robotics and infrastructure.

In connection with any tax assessment orders that have been issued or may be issued against us or our subsidiaries, we may be required to deposit additional amounts with respect to such assessment orders (see Note 24 - Commitments and Contingencies to our unaudited consolidated financial statements herein for further details). We anticipate that we will continue to rely upon cash from operating activities to finance our working capital needs, capital expenditures and smaller acquisitions. If we have significant growth through acquisitions, we may need to obtain additional financing.

The Coronavirus Aid, Relief, and Economic Security Act, (the “CARES Act”) allows employers to defer the payment of the employer share of Federal Insurance Contributions Act (“FICA”) taxes for the period from April 1, 2020 and ending December 31, 2020. As of September 30, 2021 and December 31, 2020, we deferred our contributions to FICA of $6.3 million each under the CARES Act. The deferred amount will be payable as follows: (1) 50% of the deferred amount will be paid on or before December 31, 2021 and (2) the remaining 50% of the deferred amount will be paid on or before December 31, 2022.

*Unamortized debt issuance costs for our revolving Credit Facility of $0.3 million and $0.5 million as of September 30, 2021 and December 31, 2020, respectively, is presented under “Other current assets” and “Other assets,” as applicable in our consolidated balance sheets.

On August 27, 2021, we entered into a Payoff and Termination Agreement (the “Payoff and Termination Agreement”) with the Purchaser, pursuant to which we prepaid and settled its outstanding obligations under the Notes for an aggregate consideration of $236.7 million, excluding accrued and unpaid interest under the Notes calculated through and including, August 26, 2021, in the form of a combination of cash and share of our common stock. As a result, we made a cash payment of $200.0 million to the Purchaser and satisfied the remainder of the obligation under the Notes by issuing to the Purchaser 310,394 shares of our common stock calculated at $118.37 per share based on a 20-day volume weighted average price ending on, and including, August 26, 2021. We satisfied the cash payment obligation under the Payoff and Termination Agreement by drawing $200.0 million from our existing revolving Credit Facility, and our common stock was issued from our existing treasury shares. See Note 17 - Borrowings and Note 18 - Capital Structure to our unaudited consolidated financial statements herein for further details.

Off-Balance Sheet Arrangements

In the ordinary course of business, we provide standby letters of credit to third parties primarily for facility leases. As of September 30, 2021 and December 31, 2020, we had outstanding letters of credit of $0.5 million each, that were not recognized in our unaudited and audited consolidated balance sheets, respectively. These are not reasonably likely to have, a current or future material effect on our financial condition, revenues or expenses, results of operations, liquidity, capital expenditures or capital resources. We had no other off-balance sheet arrangements or obligations.

Certain units of our Indian subsidiaries were established as 100% Export-Oriented units under the Software Technology Parks of India or Special Economic Zone 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. We have 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. We believe, however, that these units have in the past satisfied and will continue to satisfy the required conditions.

Our operations centers in the Philippines are registered with the Philippine Economic Zone Authority. The registration provides us with certain fiscal incentives on the import of capital goods and local purchase of services and materials and requires our Philippines subsidiary to meet certain performance and investment criteria. We believe that these centers have in the past satisfied and will continue to satisfy the required criteria.

ITEM 3.    Quantitative and Qualitative Disclosures About Market Risk

During the three months ended September 30, 2021, there were no material changes in our market risk exposure. For a discussion of our market risk associated with exchange rate risk and interest rate risk, see Part II, Item 7A “Quantitative and Qualitative Disclosures About Market Risk” in our Annual Report on Form 10-K for the fiscal year ended December 31, 2020.

ITEM 4.    Controls and Procedures

Evaluation of Disclosure Controls and Procedures

We maintain disclosure controls and procedures that are designed to ensure that information required to be disclosed in the reports we file or submit under the Securities Exchange Act of 1934, as amended (the “Exchange Act”) is recorded, processed, summarized and reported within the time periods specified in the U.S. Securities and Exchange Commission’s rules and forms, and that such information is accumulated and communicated to our management, including its Chief Executive Officer (“CEO”) and Chief Financial Officer (“CFO”), to allow timely decisions regarding required disclosure. In connection with the preparation of this Quarterly Report on Form 10-Q, our management carried out an evaluation, under the supervision and with the participation of the CEO and CFO, of the effectiveness and operation of our disclosure controls and procedures as of September 30, 2021. Based upon that evaluation, the CEO and CFO have concluded that our disclosure controls and procedures, as of September 30, 2021, were effective.

Changes in Internal Control over Financial Reporting

During the three months ended September 30, 2021, there were no changes in our internal control over financial reporting (as defined in Rules 13a-15(f) and 15d-15(f) under the Exchange Act) that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

PART II.     Other Information

ITEM 1.    Legal Proceedings

In the course of our normal business activities, various lawsuits, claims and proceedings may be instituted or asserted against us. Although there can be no assurance, we believe that the disposition of matters currently instituted or asserted will not have a material adverse effect on our consolidated financial position, results of operations or cash flows. See Note 24 - Commitments and Contingencies to our unaudited consolidated financial statements contained herein for details.

ITEM 1A.    Risk Factors

We have discussed under the heading “Risk Factors” in our Annual Report on Form 10-K for the fiscal year ended December 31, 2020 (the “2020 Form 10-K”), supplemented by the disclosure below, a number of risks which may materially affect our business, financial condition or results of operations. You should carefully consider these Risk Factors and other information set forth elsewhere in this Quarterly Report on Form 10-Q. You should be aware that these risk factors and other information may not describe every risk facing our Company. Additional risks and uncertainties not currently known to us may also materially adversely affect our business, financial condition and/or results of operations.

The following constitutes a supplement to the 2020 Form 10-K, Part I, Item 1A “Risk Factors” under “Our business, results of operations and financial condition have been adversely affected, and could in the future be materially adversely affected, by the coronavirus pandemic.”

In late March 2021, a new serious outbreak of COVID-19 virus began affecting India. The outbreak resulted in an exorbitant spike in the number of COVID patients, which overwhelmed the healthcare infrastructure in India. The Indian government reinstated lockdowns limiting in certain cases the movement of our employees to offices. During the same period, the Philippines also began experiencing a spike in the number of COVID patients. In July 2021, a significant increase in number of COVID-19 cases across the U.S. were brought on by the new variant of the COVID-19 virus. The situation has improved in India, the Philippines and the U.S., but we continue to monitor the situation in all of the jurisdictions in which we operate. Our operations were not materially affected in any of these geographies as a result of our appropriate business

59

continuity procedures. It is possible that any further developments, including the emergence of new variants of the COVID-19 virus, could adversely affect our business and results of operations.

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, 2020.

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, 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, purchase price allocation and recoverability of long-lived assets, goodwill and intangibles.

As of September 30, 2021, the extent to which the global Coronavirus Disease 2019 pandemic (“COVID-19”) will ultimately impact the Company's business depends on numerous dynamic factors, which the Company still cannot reliably predict. As a result, many of the Company's estimates and assumptions herein required increased judgment and carry a higher degree of variability and volatility. As events continue to evolve with respect to COVID-19, the Company’s estimates may materially change in future periods. Any changes in estimates are adjusted prospectively in the Company’s consolidated financial statements.

(c)Recent Accounting Pronouncements    

In March 2020, Financial Accounting Standard 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.

(d)Recently Adopted Accounting Pronouncements

In December 2019, FASB issued ASU No. 2019-12, Income Taxes Simplifying the Accounting for Income Taxes. This ASU eliminates certain exceptions related to the approach for intraperiod tax allocation, the methodology for calculating income taxes in an interim period and the recognition of deferred tax liabilities for outside basis differences. The Company adopted this ASU on January 1, 2021. The adoption of this ASU did not have a material impact on the Company’s unaudited consolidated financial statements.

In October 2020, FASB issued ASU No. 2020-10, Codification Improvements, to provide guidance for technical corrections such as conforming amendments, clarifications to guidance, simplifications to wording or structure of guidance, and other minor improvements. The amendments in this ASU improve the consistency of the ASC by ensuring that all guidance that requires or provides an option for an entity to provide information in the notes to financial statements is codified in the disclosure section of the ASC. The Company adopted this ASU on January 1, 2021. The adoption of this ASU did not have a material impact on the Company’s unaudited consolidated financial statements.

In January 2021, FASB issued ASU No. 2021-01, Reference Rate Reform (Topic 848): Scope, to expand the scope of Topic 848 to include derivative instruments affected by changes to the interest rates used for discounting, margining or contract price alignment (commonly referred to as the discounting transition). This ASU extends some of Topic 848’s optional expedients and exceptions for contract modifications and hedge accounting to derivative instruments impacted by discounting transition as a result of the discontinuation of the use of LIBOR as a benchmark interest rate due to reference rate reform. This ASU is effective immediately for all entities with the option to be applied retrospectively as of any date from the beginning of an interim period that includes or is subsequent to March 12, 2020, and prospectively to any new contract modifications made on or after January 7, 2021 through December 31, 2022. The adoption of this ASU did not have a material impact on the Company’s unaudited consolidated financial statements.

Segment Reporting [Abstract]

Segment and Geographical Information

Segment and Geographical InformationThe Company operates in the Business Process Management (“BPM”) industry and is a provider of operations management and analytics services.

The Company manages and reports financial information through its four strategic business units: Insurance, Healthcare, Analytics and Emerging Business. 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.

Revenues and cost of revenues for the three months ended September 30, 2021 and 2020, respectively, for each of the reportable segments, are as follows:

Accounts receivable includes $90,736 and $63,995 as of September 30, 2021 and December 31, 2020, 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. Consideration received from customers, if any, relating to such transition activities are classified under contract liabilities and are included within “Deferred revenues” and “Other non-current liabilities” in the unaudited consolidated balance sheets. The revenues are recognized as (or when) the performance obligation is fulfilled under the contract with customer.

Revenue recognized during the three and nine months ended September 30, 2021 and 2020, which was included in the contract liabilities balance at the beginning of the respective periods:

Allowance for expected credit losses

The Company evaluates the credit risk of its customers based on a combination of various financial and qualitative factors that may affect the ability of each customer to pay. The Company considered current and anticipated future economic

conditions relating to the industries of the Company’s customers and the countries where it operates. In calculating expected credit loss, the Company also considered past payment trends, credit rating and other related credit information for its significant customers to estimate the probability of default in the future and estimates relating to the possible effects resulting from COVID-19.

The duration and severity of COVID-19 and continued market volatility is highly uncertain and, as such, the impact on expected losses is subject to significant judgment, including but not limited to changes in customers’ credit rating, and may cause variability in the Company’s allowance for credit losses in future periods.

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 assumed conversion premium of outstanding convertible notes, using the treasury stock method. Common stock equivalents and the conversion premium of outstanding convertible notes 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.

Diluted weighted-average shares outstanding is 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 intended and 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 three months ended September 30, 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. Refer to Note 17 - Borrowings to the unaudited consolidated financial statements for further details.

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

As of September 30, 2021 and December 31, 2020, 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

Goodwill and Intangible Assets

Goodwill

The Company transitioned to new segment reporting structure effective January 1, 2020, which resulted in certain changes to its operating segments and reporting units. The Company reallocated goodwill to its reporting units using a relative fair value approach. In addition, the Company completed an assessment of any potential goodwill impairment for all its reporting units immediately prior to the reallocation and determined that no impairment existed.

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, 2021	$	50,499	$	21,953	$	49,348	$	227,288	$	349,088
Currency translation adjustments	(77)		(11)		(301)		—		(389)
Balance at September 30, 2021	$	50,422	$	21,942	$	49,047	$	227,288	$	348,699

During the fourth quarter of 2020, 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 September 30, 2021, 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 continued improvements in current and forecasted economic and market conditions and qualitative factors, for instance, the Company’s performance during the first three quarters, business forecasts for the remainder of the year, stock price movements and the Company’s expansion plans.

The Company did not identify any triggers or indications of potential impairment for its reporting units as of September 30, 2021.

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.

Accumulated Other Comprehensive Income (Loss), Net of Tax [Abstract]

Accumulated Other Comprehensive Loss

Accumulated Other Comprehensive LossAccumulated other comprehensive loss (“AOCL”) consists of actuarial gain/(loss) on retirement benefits and foreign currency translation adjustments. In addition, the Company enters into foreign currency exchange contracts, which are designated as cash flow hedges and net investment hedges in accordance with ASC 815. Cumulative changes in the fair values of these foreign currency exchange contracts are recognized in AOCL on the Company's unaudited consolidated balance sheets. Upon settlement of foreign exchange contracts designated as cash flow hedges, fair value changes are reclassified from AOCL to net income, whereas such fair value changes related to net investment hedges are included in net income when a foreign operation is disposed or partially disposed.

* Represents those short-term investments, which are carried at the fair value option under ASC 825 "Financial Instruments.”

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.

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, 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.

Convertible Senior Notes:

The Company settled the Notes during the three months ended September 30, 2021. Refer to Note 17 - Borrowings to the unaudited consolidated financial statements for further details.

The total estimated fair value of the Notes as of December 31, 2020 was $152,384. The fair value was determined based on market yields for similar convertible notes as of December 31, 2020. The Company considers the fair value of the Notes to be a Level 2 measurement due to the limited inputs available for its fair valuation.

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 $515,850 as of September 30, 2021 and $451,935 as of December 31, 2020.

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,” “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 $5,695 of derivative gains, net, excluding tax effects, included in AOCL, 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 September 30, 2021. At September 30, 2021, the maximum outstanding term of the cash flow hedges was 45 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 140,119, GBP 5,911, EUR 1,005 and COP 4,675,248 as of September 30, 2021 and USD 143,394, GBP 6,753, EUR 2,447 and COP 8,287,950 as of December 31, 2020.

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 AOCL 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.

Credit Agreement

The Company’s $300,000 revolving credit facility pursuant to its credit agreement (the “Credit Agreement”) with certain lenders and Citibank N.A. as Administrative Agent (the “Credit Facility”) carried an effective interest rate as shown below.

	Three months ended September 30,				Nine months ended September 30,

Effective Interest Rate	2.3	%	1.9	%	2.0	%	2.4	%

As of September 30, 2021 and December 31, 2020, the Company was in compliance with all financial and non-financial covenants listed under the Credit Agreement.

Convertible Senior Notes

On October 1, 2018, the Company entered into an investment agreement (the “Investment Agreement”) with Orogen Echo LLC (the “Purchaser”), an affiliate of The Orogen Group LLC, relating to the issuance to the Purchaser of $150,000, in an aggregate principal amount of the Notes. The transactions contemplated by the Investment Agreement, including the issuance of the Notes, closed on October 4, 2018. The Notes carried interest at a rate of 3.5% per annum, payable semi-annually in arrears in cash on April 1 and October 1 of each year. The Notes were convertible at an initial conversion rate of 13.3333 shares of the common stock per one thousand dollar principal amount of the Notes (which represented an initial conversion price of approximately $75 per share). The Company had the option to redeem the principal amount of the Notes, at its option, in whole but not in part, at a purchase price equal to the principal amount plus accrued and unpaid interest on or after October 1, 2021, if the closing sale price of the common stock exceeded 150% of the then-current conversion price for 20 or more trading days in the 30 consecutive trading day period preceding the Company’s exercise of this redemption right (including the trading day immediately prior to the date of the notice of redemption). The Company had the option to elect to settle conversions of the Notes by paying or delivering, as the case may be, cash, shares of the Company’s common stock or a combination of cash and shares of the Company’s common stock.

The Notes carried an effective interest rate as shown below:

	Three months ended September 30,				Nine months ended September 30,
	2021		2020		2021		2020
Effective Interest Rate	3.6	%	3.6	%	3.6	%	3.6	%

On August 27, 2021, the Company entered into a Payoff and Termination Agreement (the “Payoff and Termination Agreement”) with the Purchaser, pursuant to which the Company prepaid and settled its outstanding obligations under the Notes for an aggregate consideration of $236,742, excluding accrued and unpaid interest under the Notes calculated through, and including, August 26, 2021, in the form of a combination of cash and shares of the Company’s common stock. As a result, the Company made a cash payment of $200,000 to the Purchaser and satisfied the remainder of the obligation under the Notes by issuing to the Purchaser 310,394 shares of the Company’s common stock calculated at $118.37 per share based on a 20-day volume weighted average price ending on, and including, August 26, 2021. The Company satisfied the cash payment obligation under the Payoff and Termination Agreement by drawing $200,000 from its existing revolving Credit Facility, and the Company’s common stock was issued from its existing treasury shares. Refer to Note 18 - Capital Structure to the unaudited consolidated financial statements for further details.

The aggregate consideration of $236,742 was allocated between the debt and equity components in an amount of $152,742 and $84,000, respectively. The consideration was first allocated to the fair value of debt component and the remaining was allocated to the equity component. The fair value of the debt component was calculated using a discounted cash flow technique, which considered debt issuances with similar features of the Company’s debt, without the conversion feature. The resulting effective interest rate for the Notes was 2.9% per annum at the time of settlement. The portion allocated to the equity component was recorded as additional paid-in capital.

Immediately prior to the settlement of the Notes, the carrying amount of the debt component of the Notes, net of unamortized debt discount and issuance costs, was $139,897. During the three months ended September 30, 2021, the Company recognized a loss on settlement of the Notes of $12,845, representing the difference between the fair value of the consideration allocated to the debt component and the carrying value of the debt component immediately before settlement, and is presented as “Loss on settlement of convertible notes,” in the Company’s unaudited consolidated statements of income.

During the three and nine months ended September 30, 2021 and 2020, the Company recognized interest expense and amortization of debt discount, on the Notes as below:

	Three months ended September 30,				Nine months ended September 30,
	2021		2020		2021		2020
Interest expense on the Notes	$	817	$	1,313	$	3,442	$	3,938
Amortization of debt discount on the Notes	$	431	$	654	$	1,795	$	1,943

Employee Benefit Plans

The Company’s Gratuity Plan in India (the "India Plan") provides for a 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. In addition, the Company’s subsidiary operating in the Philippines conforms to the minimum regulatory benefit, which provide for lump sum payment to vested employees on retirement from employment in an amount based on the respective employee’s salary and years of employment with the Company (the "Philippines Plan"). Liabilities with regard to the India Plan and the Philippines Plan are determined by actuarial valuation using the projected unit credit method. Current service costs for these Plans 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.

Components of net periodic benefit costs, were as follows:

	Three months ended September 30,				Nine months ended September 30,
	2021		2020		2021		2020

Leases [Abstract]

Leases

Leases

The 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. During the nine months ended September 30, 2021 and year ended December 31, 2020, the Company changed the lease term for certain of its leases and recognized the resultant amount of the remeasurement of the lease liability as an 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.

During the nine months ended September 30, 2021 and year ended December 31, 2020, the Company modified certain of its operating leases, resulting in a reduction of its lease liabilities by $1,022 and $3,143 respectively, with a corresponding reduction in ROU assets.

As of September 30, 2021, the Company did not have any significant leases that have not yet commenced but that create significant rights and obligations for the Company.

Leases

Leases

The 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. During the nine months ended September 30, 2021 and year ended December 31, 2020, the Company changed the lease term for certain of its leases and recognized the resultant amount of the remeasurement of the lease liability as an 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 decreased from 24.3% during the three months ended September 30, 2020 to 13.7% during the three months ended September 30, 2021. The Company recorded income tax expense of $4,196 and $8,490 for the three months ended September 30, 2021 and 2020, respectively. The decrease in income tax expense was primarily a result of (i) the recording of a one-time deferred tax benefit of $2,400 on settlement of the Notes during the three months ended September 30, 2021, (ii) the recording of excess tax benefits related to stock awards of $528 pursuant to ASU No. 2016-09 during the three months ended September 30, 2021, and (iii) lower profit during the three months ended September 30, 2021, compared to the three months ended September 30, 2020.

The Company's effective tax rate decreased from 24.3% during the nine months ended September 30, 2020 to 20.3% during the nine months ended September 30, 2021. The Company recorded income tax expense of $22,019 and $18,416 for the nine months ended September 30, 2021 and 2020, respectively. The increase in the income tax expense was primarily a result of higher profit during the nine months ended September 30, 2021, compared to the nine months ended September 30, 2020, and the recording of higher excess tax benefits related to stock awards of $1,874 pursuant to ASU No. 2016-09 during the nine months ended September 30, 2020, compared to $1,556 during the nine months ended September 30, 2021, partially offset by (i) the recording of a one-time deferred tax benefit of $2,400 on settlement of the Notes during the nine months ended September 30, 2021, and (ii) the recording of a one-time tax expense of $1,320 due to election of a new tax regime, during the nine months ended September 30, 2020, for two of the Company's Indian subsidiaries that provides for a lower tax rate on earnings in exchange for foregoing certain tax credits, including minimum alternative tax credits.

During the three months ended September 30, 2021, the Company repatriated to the United States $17,000 (net of $908 withholding taxes) from India. During the nine months ended September 30, 2021, the Company repatriated to the United States $66,000 (net of $3,494 withholding taxes) from India and $42,500 (net of $7,494 withholding taxes) from the Philippines. As of September 30, 2021, the Company accrued withholding taxes of $10,988 associated with these distributions and increased the Company’s deferred tax assets. These distributions do not constitute a change in the Company’s permanent reinvestment assertion. The Company bases its decision to continue to indefinitely reinvest earnings in India and the Philippines on its estimate of the working capital required to support its operations in these geographies and periodically reviews its capital initiatives to support and expand the Company’s global operations, as well as an economically viable rate of return on its investments made in India and the Philippines as compared to those made in the United States.

Commitments and Contingencies Disclosure [Abstract]

Commitments and Contingencies

Commitments and Contingencies

Capital Commitments

At September 30, 2021, the Company had committed to spend approximately $5,200 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 or Special Economic Zone 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 and investment criteria. The Company believes that these centers have in the past satisfied and will continue to satisfy the required criteria.

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 entities that are unrelated. 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. Further, the Company and a U.S. subsidiary are engaged in tax litigation with Indian tax authorities regarding a permanent establishment matter. For the United States, the Philippines and India, tax year 2016 and subsequent tax years remain open for examination by the tax authorities as of September 30, 2021.

The aggregate amount demanded by Indian tax authorities (net of advance payments, if any) 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 September 30, 2021 and December 31, 2020 is $34,399 and $16,748, respectively. The Company has made payments and/or provided bank guarantees against these demands in the amounts of $8,014 and $8,120, respectively. Amounts paid as deposits in respect of such assessments aggregating to $6,229 and $6,307 as of September 30, 2021 and December 31, 2020, respectively, are included in “Other assets” and amounts deposited for bank guarantees aggregating to $1,785 and $1,813

as of September 30, 2021 and December 31, 2020, respectively, are included in “Restricted cash” in the non-current assets section of the Company’s unaudited and audited consolidated balance sheets, respectively.

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 unaudited 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.

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.

Summary of Significant Accounting Policies (Policies)

9 Months Ended

Sep. 30, 2021

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, 2020.

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, 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, purchase price allocation and recoverability of long-lived assets, goodwill and intangibles.

As of September 30, 2021, the extent to which the global Coronavirus Disease 2019 pandemic (“COVID-19”) will ultimately impact the Company's business depends on numerous dynamic factors, which the Company still cannot reliably predict. As a result, many of the Company's estimates and assumptions herein required increased judgment and carry a higher degree of variability and volatility. As events continue to evolve with respect to COVID-19, the Company’s estimates may materially change in future periods. Any changes in estimates are adjusted prospectively in the Company’s consolidated financial statements.

Recent Accounting Pronouncements and Recently Adopted Accounting Pronouncements

Recent Accounting Pronouncements    

In March 2020, Financial Accounting Standard 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.

(d)Recently Adopted Accounting Pronouncements

In December 2019, FASB issued ASU No. 2019-12, Income Taxes Simplifying the Accounting for Income Taxes. This ASU eliminates certain exceptions related to the approach for intraperiod tax allocation, the methodology for calculating income taxes in an interim period and the recognition of deferred tax liabilities for outside basis differences. The Company adopted this ASU on January 1, 2021. The adoption of this ASU did not have a material impact on the Company’s unaudited consolidated financial statements.

In October 2020, FASB issued ASU No. 2020-10, Codification Improvements, to provide guidance for technical corrections such as conforming amendments, clarifications to guidance, simplifications to wording or structure of guidance, and other minor improvements. The amendments in this ASU improve the consistency of the ASC by ensuring that all guidance that requires or provides an option for an entity to provide information in the notes to financial statements is codified in the disclosure section of the ASC. The Company adopted this ASU on January 1, 2021. The adoption of this ASU did not have a material impact on the Company’s unaudited consolidated financial statements.

In January 2021, FASB issued ASU No. 2021-01, Reference Rate Reform (Topic 848): Scope, to expand the scope of Topic 848 to include derivative instruments affected by changes to the interest rates used for discounting, margining or contract price alignment (commonly referred to as the discounting transition). This ASU extends some of Topic 848’s optional expedients and exceptions for contract modifications and hedge accounting to derivative instruments impacted by discounting transition as a result of the discontinuation of the use of LIBOR as a benchmark interest rate due to reference rate reform. This ASU is effective immediately for all entities with the option to be applied retrospectively as of any date from the beginning of an interim period that includes or is subsequent to March 12, 2020, and prospectively to any new contract modifications made on or after January 7, 2021 through December 31, 2022. The adoption of this ASU did not have a material impact on the Company’s unaudited consolidated financial statements.
