NOTES TO UNAUDITED CONSOLIDATED FINANCIAL STATEMENTS

March 31, 2019

(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”), operates in the Business Process Management (“BPM”) industry providing operations management services and analytics services that help businesses enhance revenue growth and improve profitability. Using its proprietary platforms, methodologies and tools, the Company looks deeper to help companies improve global operations, enhance data-driven insights, increase customer satisfaction, and manage risk and compliance. 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 (“US 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 US 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, 2018.

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 income and expenses arising from intra-group transactions, are eliminated while preparing those 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 US GAAP.

The Company’s investments in equity affiliates are initially recorded at cost and any excess cost 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 is recognized in the unaudited consolidated statements of income.

Non-controlling interest is the equity in a subsidiary not attributable, directly or indirectly, to the parent and it represents the minority partner’s interest in the operations of ExlService Colombia S.A.S. Non-controlling interest consists of the amount of such interest at the date of obtaining control over the subsidiary, and the non-controlling interest's share of changes in equity since that date. The non-controlling interest in the operations for all periods presented were insignificant and is included under general and administrative expenses in the unaudited consolidated statements of income.

(b) Use of Estimates

The preparation of the unaudited consolidated financial statements in conformity with US GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the 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 financial statements include, but are not limited to, allowance for doubtful receivables, expected recoverability from customers with contingent fee arrangements, 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 incremental borrowing rate to calculate lease liabilities and right-of-use (“ROU”) assets, lease term to calculate lease cost, depreciation and amortization periods,

(In thousands, except share and per share amounts)

purchase price allocation, recoverability of long-lived assets including goodwill and intangibles, and estimated costs to complete fixed price contracts.

(c) Employee Benefits

Contributions to defined contribution plans are charged to the unaudited consolidated statements of income in the period in which services are rendered by the covered employees. Current service costs for defined benefit plans are accrued in the period to which they relate. The liability in respect of defined benefit plans is calculated annually by the Company using the projected unit credit method. Prior service cost, if any, resulting from an amendment to a plan is recognized and amortized over the remaining period of service of the covered employees.

The Company recognizes its liabilities for compensated absences depending on whether the obligation is attributable to employee services already rendered, relates to rights that vest or accumulate and payment is probable and estimable.

The Company includes the service cost component of the net periodic benefit cost in the same line item or items as other compensation costs arising from services rendered by the respective employees during the period. The interest cost, expected return on plan assets and amortization of actuarial gains/loss are classified in “Other income, net”. Refer Note 20 to the unaudited consolidated financial statements for details.

(d) Cash and Cash Equivalents and Restricted Cash

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

Restricted cash represents amounts on deposit with banks against bank guarantees issued through banks in favor of relevant statutory authorities for equipment imports, deposits for obtaining indirect tax registrations and for demands against pending income tax assessments (refer Note 26 to the unaudited consolidated financial statements for details). These deposits with banks have maturity dates after March 31, 2020. Restricted cash presented under current assets represents funds held on behalf of clients in dedicated bank accounts.

For purposes of the unaudited statements of cash flows, the Company includes in its cash and cash-equivalent balances those amounts that have been classified as restricted cash and restricted cash equivalents.

(e) Revenue Recognition

Revenue is recognized when services are provided to our customers, in an amount that reflects the consideration we expect to be entitled to in exchange for our services.

Revenue is measured based on consideration specified in a contract with a customer and excludes discounts and amounts collected on behalf of third parties. The Company recognizes revenue when it satisfies a performance obligation by providing services to a customer.

Taxes assessed by a governmental authority that are both imposed on and concurrent with a specific revenue-producing transaction, that are collected by the Company from a customer, are excluded from revenue.  

Adoption of ASU 2014-09 Topic 606, “Revenue from Contracts with Customers” (Topic 606)

On January 1, 2018, the Company adopted Topic 606 using the modified retrospective method and applied its guidance to those contracts which were not completed as of January 1, 2018. Results for reporting periods beginning after January 1, 2018 are presented under Topic 606. The effect from the adoption of Topic 606 was not material to the Company's financial statements.

Nature of services

The Company derives its revenues from operations management and analytics services. The Company operates in the business process management (“BPM”) industry providing operations management and analytics services helping businesses enhance revenue growth and improve profitability. The Company provides BPM or “operations management” services, which typically involve transfer to the Company of business operations of a client, after which it administers and manages those operations for its client on an ongoing basis. The Company also provides industry-specific digital transformational services related to operations management services, and analytics services that focus on driving improved business outcomes for clients by generating data-driven insights across all parts of their business. The Company also provides care optimization and reimbursement optimization

services, for its clients through its healthcare analytics solutions and services. The Company offers integrated solutions to help its clients with cost containment by leveraging technology platforms, customizable and configurable analytics and expertise in healthcare reimbursements to help clients enhance their claims payment accuracy.

Type of Contracts

i. a) Revenues under time-and-material, transaction and outcome-based contracts are recognized as the services are performed. When the terms of the client contract specify service level parameters that must be met (such as turnaround time or accuracy), the Company monitors such service level parameters to determine if any service credits or penalties have been incurred. Revenues are recognized net of any penalties or service credits that are due to a client.

b) In respect of arrangements involving subcontracting, in part or whole of the assigned work, the Company evaluates whether it is in control of the services before the same are transferred to the customer to assess whether it is Principal or Agent in the arrangement based on guidance on “Principal versus agent considerations” in Topic 606.

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

iii. Revenues from the Company's software and related services contracts, which are not significant, are primarily related to maintenance renewals or incremental license fees for additional users. Maintenance revenues are generally recognized on a straight-line basis over the annual contract term. Fees for incremental license without any associated services are recognized upon delivery of the related incremental license. To a lesser extent, software and related services contracts may contain software license, related services and maintenance elements as a multiple element arrangement. In such cases, revenue is allocated to maintenance based on the price charged when that element is sold separately.

iv. Revenues from reimbursement optimization services having contingent fee arrangements are recognized by the Company at the point in time when a performance obligation is satisfied, which is when it identifies an overpayment claim and the same is acknowledged by its customers. In such contracts, the Company’s consideration is contingent upon the actual collections made by its customers and subsequent potential retraction claims. Based on guidance on “variable consideration” in Topic 606, the Company uses its historical experience and projections to determine the expected recoveries from its customers and recognizes revenue based upon such expected recoveries. Any adjustment required due to change in estimates are recorded in the period in which such change is identified.

Arrangements with Multiple Performance Obligations

The Company’s contracts with customers do not generally bundle different services together except for software and related services contracts, which are not significant, involving implementation services and post contract maintenance services. In such software and related services contracts, revenue is allocated to each performance obligation based on the relative standalone selling price.

A separate contract is generally drafted for each type of service sold, even if to the same customer. The typical length of a contract is 3 to 5 years for our operations management contracts.

Allocation of transaction price to performance obligations

The transaction price is allocated to performance obligations on a relative standalone selling price basis. Standalone selling prices are estimated by reference to the total transaction price less the sum of the observable standalone selling prices of other goods or services promised in the contract.  In assessing whether to allocate variable consideration to a specific part of the contract,

10

NOTES TO UNAUDITED CONSOLIDATED FINANCIAL STATEMENTS—(continued)

March 31, 2019

(In thousands, except share and per share amounts)

the Company considers the nature of the variable payment and whether it relates specifically to its efforts to satisfy a specific part of the contract.

Variable Consideration

Variability in the transaction price arises primarily due to service level agreements, cost of living adjustments, and pre-payment and volume discounts.

The Company considers its experience with similar transactions and expectations regarding the contract in estimating the amount of variable consideration that should be recognized during a period.

The Company believes that the expected value method is most appropriate for determining the variable consideration since the company has large number of contracts with similar nature of transactions/services.

Unbilled Receivables

Unbilled receivables represents revenues recognized for services rendered between the last billing date and the balance sheet date. Unbilled receivables also include revenues recognized from reimbursement optimization services when the Company identifies an overpayment claim and the same is acknowledged by its customers, however not invoiced at the balance sheet date. Accordingly, amounts for services that the Company has performed and for which an invoice has not yet been issued to the customers are presented as a part of contract assets as accounts receivable.

Deferred Revenue

The Company has deferred revenue attributable to certain process transition activities, with respect to its customers where such activities do not represent separate performance obligations. Revenues related to such transition activities are contract liabilities classified under “Deferred Revenue” in the Company's unaudited consolidated balance sheets and subsequently recognized ratably over the period in which the related services are performed. Deferred revenue also includes the amount for which services have been rendered but other conditions of revenue recognition are not met, for example where the Company does not have persuasive evidence of an arrangement with customer. Costs related to such transition activities are contract fulfillment costs, and thereby classified under “Other Current Assets” and “Other Assets” in the unaudited consolidated balance sheets, and are recognized ratably over the estimated expected period of benefit, under Cost of Revenues in the unaudited consolidated statements of income.

Other incremental and direct costs incurred for acquiring contracts, such as sales commissions are contract acquisition costs and thereby classified under “Other Current Assets” and “Other Assets” in the unaudited consolidated balance sheets. Such costs are amortized over the expected period of benefit and recorded under Selling and marketing expenses in the unaudited consolidated statements of income.

Any upfront payments made to customers are contract assets and classified under “Other Current Assets and Other Assets” in the unaudited consolidated balance sheets. Such costs are amortized over the expected period of benefit and are recorded as an adjustment to transaction price and reduced from revenues.

Reimbursements of out-of-pocket expenses received from clients are included as part of revenues.

Payment terms

All Contracts entered into by the Company specify the payment terms and are defined for each contract separately. Usual payment terms range between 30-60 days. The Company does not have any extended payment terms clauses in existing contracts. At times, the Company enters into fixed price contracts and software licenses involving significant implementation wherein the milestones are defined such that the Company can recover the costs with a reasonable margin.

Practical expedients and exemptions

The Company does not disclose the value of unsatisfied performance obligations for (i) contracts with an original expected length of 1 year or less and (ii) contracts for which the Company recognizes revenue at the amount to which we have the right to invoice for services performed.

Accounts Receivable

We record accounts receivable net of allowances for doubtful accounts. Allowances for doubtful accounts are established through the evaluation of aging of accounts receivables, prior collection experience, current market conditions, clients’ financial condition and the amount of accounts receivables in dispute to estimate the collectability of these accounts receivables.

(f) Leases

The Company determines if an arrangement is a lease at inception. Operating leases are included in operating lease right-of-use ("ROU") assets, current portion of operating lease liabilities and operating lease liabilities, less current portion in the Company's unaudited consolidated balance sheets. Finance leases are included in property and equipment, current portion of finance lease obligations and finance lease obligations, less current portion in the Company's unaudited consolidated balance sheets.

ROU assets represent the Company’s right to use an underlying asset for the lease term and lease liabilities represent the Company’s obligation to make lease payments arising from the lease. Operating lease ROU assets and liabilities are recognized at commencement date based on the present value of lease payments over the lease term. For leases in which the rate implicit in the lease is not readily determinable, the Company uses its incremental borrowing rate based on the information available at commencement date in determining the present value of lease payments. Lease terms include options to extend or terminate the lease when it is reasonably certain that the Company will exercise that option. Lease expense for operating lease arrangements is recognized on a straight-line basis over the lease term. The Company has lease agreements with lease and non-lease components, which are accounted for separately.

On January 1, 2019, the date of initial application, the Company adopted, Leases (Topic 842), using the modified retrospective method. The modified retrospective method provides a method of recording those leases which had not expired as of the date of adoption of January 1, 2019. The prior period unaudited consolidated financial statements have not been retrospectively adjusted and continues to be reported under Topic 840.

The Company elected the practical expedient permitted under the transition guidance under Topic 842, which amongst other matters, allowed the Company (i) not to apply the recognition requirements to short-term leases (leases with a lease term of 12 months or less), (ii) not to reassess whether any expired or existing contracts are or contain leases, (iii) not to reassess the lease classification for any expired or existing leases, and (iv) not to reassess initial direct costs for any existing leases.

The adoption resulted in the recognition of ROU assets of $80,328, net of deferred rent of $8,626 and lease liabilities of $88,954 for operating leases as of January 1, 2019. The Company's accounting for finance leases remained substantially unchanged. The adoption had no impact on opening balance of retained earnings.

Refer Note 21 to the unaudited consolidated financial statements for details.

(g) Recent Accounting Pronouncements    

In June 2016, the Financial Accounting Standards Board ("FASB") issued ASU No. 2016-13, Financial Instruments - Credit Losses, which requires a financial asset (or a group of financial assets) measured at amortized cost basis to be presented at the net amount expected to be collected. The allowance for credit losses is a valuation account that is to be deducted from the amortized cost of the financial asset(s) so as to present the net carrying value at the amount expected to be collected on the financial asset. The new guidance is effective for fiscal years beginning after December 15, 2019, including interim periods within those fiscal years. The amendment should be applied through a modified retrospective approach. Early adoption as of the fiscal years beginning

12

EXLSERVICE HOLDINGS, INC.

NOTES TO UNAUDITED CONSOLIDATED FINANCIAL STATEMENTS—(continued)

March 31, 2019

(In thousands, except share and per share amounts)

after December 15, 2018 is permitted. The Company is currently evaluating the impact that the adoption of this guidance will have on its consolidated financial statements.

In June 2018, FASB issued ASU No. 2018-07, Compensation-Stock Compensation (Topic 718): Improvements to Non-employee Share-Based Payment Accounting. This ASU involves several aspects of the accounting for non-employee share-based payment transactions resulting from expanding the scope of Topic 718, Compensation-Stock Compensation, to include share-based payment transactions for acquiring goods and services from non-employees. The amendments in this ASU affect all entities that enter into share-based payment transactions for acquiring goods and services from non-employees. This ASU is effective for public business entities for fiscal years beginning after December 15, 2018, including interim periods within that fiscal year.  Early adoption is permitted, but no earlier than an entity’s adoption date of Topic 606. The adoption of this ASU is not expected to have any material effect on the Company’s consolidated financial statements.

In August 2018, FASB issued ASU No. 2018-13, Fair Value Measurement (Topic 820): Changes to the Disclosure Requirements for Fair Value Measurement. The amendments in this ASU modify the disclosure requirements on fair value measurements in Topic 820, based on the concepts in the Concepts Statement, including the consideration of costs and benefits. The amendments in ASU are effective for fiscal years beginning after December 15, 2019, including interim periods within those fiscal years. An entity is permitted to early adopt either the entire standard or only the provisions that eliminate or modify requirements. The adoption of this ASU is not expected to have any material effect on the Company’s consolidated financial statements.

In August 2018, FASB issued ASU No. 2018-14, Compensation-Retirement Benefits-Defined Benefit Plans-General (Subtopic 715-20): Changes to the Disclosure Requirements for Defined Benefit Plans. The amendments in this Update remove disclosures that no longer are considered cost beneficial, clarify the specific requirements of disclosures, and add disclosure requirements identified as relevant. The amendments in ASU are effective for fiscal years beginning after December 15, 2020. An entity is permitted to early adopt this Update. The adoption of this ASU is not expected to have any material effect on the Company’s consolidated financial statements.

In August 2018, FASB issued ASU No. 2018-15, Intangibles - Goodwill and Other - Internal-Use Software (Subtopic 350-40): This ASU aligns the requirements for capitalizing implementation costs incurred in a hosting arrangement that is a service contract with the requirements for capitalizing implementation costs incurred to develop or obtain internal-use software (and hosting arrangements that include an internal-use software license). Accordingly, the ASU requires an entity (customer) in a hosting arrangement that is a service contract to follow the guidance in FASB Accounting Standard Codification Subtopic 350-40 on internal-use software to determine which implementation costs to capitalize as an asset related to the service contract and which costs to expense. The ASU 2018-15 also provides guidance on amortization and impairment of any costs capitalized, along with new presentation and disclosure requirements. The new guidance is effective for fiscal years beginning after December 15, 2019.  Early adoption is permitted and both prospective and retrospective transition methods are allowed. The Company is currently evaluating the impact that the adoption of this guidance will have on its consolidated financial statements.

(h) Recently Adopted Accounting Pronouncements

In February 2016, FASB issued ASU No. 2016-02, Leases (Topic 842), which requires the identification of arrangements that should be accounted for as leases. Lease arrangements exceeding a twelve months term should be recognized as assets with corresponding liabilities on the balance sheet of the lessee. This ASU requires recognition of an ROU asset and lease obligation for those leases classified as operating leases under Topic 840, while the income statement will reflect lease expense for operating leases. The balance sheet amounts recorded for existing operating leases at the date of adoption of this ASU must be calculated using the applicable incremental borrowing rate. The Company adopted Topic 842 as of January 1, 2019 using the modified retrospective method provided by ASU 2018-11. The adoption had a material impact on the Company's unaudited consolidated balance sheets, but did not have a material impact on the Company's unaudited consolidated income statements and unaudited consolidated statements of cash flows. The most significant impact was the recognition of ROU assets and lease liabilities for operating leases, while the Company's accounting for finance leases remained substantially unchanged. Refer Note 21 to the unaudited consolidated financial statements for details.

In July 2018, FASB issued ASU No. 2018-11, Leases (Topic 842), which provide entities with an additional (and optional) transition method to adopt the new leases standard. Under this new transition method, an entity initially applies the new leases standard at the adoption date and recognizes a cumulative-effect adjustment to the opening balance of retained earnings in the period of adoption. Consequently, an entity’s reporting for the comparative periods presented in the financial statements in which

it adopts the new leases standard will continue to be in accordance with current GAAP (Topic 840, Leases). The Company adopted Topic 842 as of January 1, 2019 using this ASU. Refer Note 21 to the unaudited consolidated financial statements for details.

3. Segment and Geographical Information

The Company operates in the BPM industry and is a provider of operations management and analytics services. The Company has eight operating segments, which are strategic business units that align its products and services with how it manages its business, approaches its key markets and interacts with its clients. Six of those operating segments provide BPM or “operations management” services, five of which are industry-focused operating segments (Insurance, Healthcare, Travel, Transportation and Logistics, Banking and Financial Services, and Utilities) and one of which is a “capability” operating segment (Finance and Accounting) that provides services to clients in our industry-focused segments as well as clients across other industries. In each of these six operating segments, the Company provides operations management services, which typically involve transfer to the Company of the business operations of a client, after which it administers and manages those operations for its client on an ongoing basis. The remaining two operating segments are Consulting, which provides industry-specific transformational services related to operations management services, and Analytics, which provides services that focus on driving improved business outcomes for clients by generating data-driven insights across all parts of their business.

The Company presents information for the following reportable segments:

• Insurance

• Healthcare

• Travel, Transportation and Logistics (“TT&L”)

• Finance and Accounting (“F&A”)

• Analytics, and

• All Other (consisting of the Company's remaining operating segments, which are the Banking and Financial Services, Utilities and Consulting operating segments).

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 other 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 March 31, 2019 and 2018, respectively, for each of the reportable segments, are as follows:

5. Earnings Per Share

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

During the three months ended March 31, 2019, the Company performed an impairment test of its long-lived assets of its Health Integrated business. Based on the results, the long-lived assets carrying value exceeded their fair value. The primary factor contributing to a reduction in the fair value is the commencement of the wind down of the Health Integrated business, and an anticipated reduction to the Company's estimated future cash flows. As a result of this analysis, the Company recognized a provisional impairment charge of $1,227 during the three months ended March 31, 2019 to write down the carrying value of internally developed software to its fair value. This impairment loss was recorded in the unaudited consolidated statements of income under "impairment charges".

9. Business Combinations, Goodwill and Intangible Assets

SCIOinspire Holdings Inc.

On July 1, 2018, the Company, through its wholly owned subsidiary ExlService.com, LLC (“Buyer”) and Buyer’s wholly owned subsidiary, ExlService Cayman Merger Sub, completed the acquisition of SCIO pursuant to an Agreement of Merger dated April 28, 2018 (the "Merger Agreement"). ExlService Cayman Merger Sub, merged with and into SCIO, with SCIO surviving the merger as a wholly-owned subsidiary of the Buyer.

SCIO is a health analytics solution and services company serving healthcare organizations including providers, health plans, pharmacy benefit managers, employers, health services and global life sciences companies. The acquisition is expected to significantly strengthen the Company’s capability in the high growth cost optimization and care optimization markets. The acquisition of SCIO is included in the Analytics reportable segment.

The aggregate purchase consideration was $245,044, including cash and cash equivalents acquired and post-closing adjustments. The aggregate base purchase consideration payable at closing of the merger was $236,500 based on completion of diligence, which was adjusted based on, among other things, SCIO’s cash, debt, working capital position and other adjustments as of the Closing as set forth in the Merger Agreement. To finance the acquisition at Closing, the Company utilized its revolving Credit Facility in the amount of $233,000, issued 69,459 shares of restricted common stock of the Company in the amount of $4,080 and paid the balance with available cash on hand.

Pursuant to the Company’s business combinations accounting policy, the total purchase consideration for SCIO was allocated to identifiable net tangible and intangible assets based upon their preliminary fair values. The excess of the purchase consideration over fair value of identifiable net tangible and intangible assets was recorded as goodwill. In order to allocate the consideration transferred for SCIO, the fair values of all identifiable assets and liabilities were established. For accounting and financial reporting

purposes, fair value is defined under ASC No. 820, Fair Value Measurement and Disclosure, as the price that would be received upon sale of an asset or the amount paid to transfer a liability in an orderly transaction between market participants at the measurement date. Market participants are assumed to be buyers and sellers in the principal (most advantageous) market for the asset or liability. Additionally, fair value measurements for an asset assume the highest and best use of that asset by market participants. Use of different estimates and judgments could yield different results.

The fair value of assets acquired and liabilities assumed from the acquisition of SCIO is based on a preliminary valuation. The primary areas of the purchase price that are not yet finalized are related to direct and indirect taxes, and, as such, the Company's estimates and assumptions are subject to change within the measurement period.

The Company’s preliminary purchase price allocation to net tangible and intangible assets of SCIO is as follows:

Assets:
Cash and cash equivalents	$	9,842
Restricted cash	2,790
Accounts receivable	19,924
Other current assets	2,076
Property and equipment	1,824
Other assets	1,751
Intangible assets
Customer relationships	47,800
Developed technology	21,400
Trade names and trademarks	3,700
	111,107
Liabilities:
Current liabilities	(12,482		)
Deferred tax liabilities, net	(17,132		)
Other non-current liabilities	(200		)
	(29,814		)
Net assets acquired	$	81,293
Goodwill	163,751
Total purchase consideration	$	245,044

The fair values of the trade names and trademarks intangible assets were determined by using an “income approach”, specifically the relief-from-royalty approach. The basic principle of the relief-from-royalty method is that without ownership of the subject intangible asset, the user of that intangible asset would have to make a stream of payments to the owner of the asset in return for the rights to use that asset. By acquiring the intangible asset, the user avoids these payments. Therefore, a portion of SCIO’s earnings, equal to the after-tax royalty that would have been paid for the use of the asset, can be attributed to the firm’s ownership. The trade names and trademarks are being amortized on a straight-line basis (which approximates the economic pattern of benefits) over the estimated economic life of 3 years.

The fair values of the developed technology intangible assets were also determined by the relief-from-royalty approach. Similarly, this approach is based on the assumption that in lieu of ownership, a firm would be willing to pay a royalty in order to exploit the related benefits of the technology. Therefore, a portion of SCIO’s earnings, equal to the after-tax royalty that would have been paid for the use of the technology, can be attributed to the firm’s ownership of the technology. The technology assets are being amortized on a straight-line basis (which approximates the economic pattern of benefits) over the estimated economic life of 5 years.

The fair values of the customer relationships were determined by using an “income approach”, specifically the Multi-Period Excess Earnings Method ("MPEEM"). The MPEEM is a specific application of the discounted cash flow method. The principle behind the MPEEM is that the value of an intangible asset is equal to the present value of the incremental after-tax cash flows attributable only to the subject intangible asset after deducting Contributory Asset Charges ("CAC"). The principle behind a CAC is that an intangible asset ‘rents’ or ‘leases’ from a hypothetical third party all the assets it requires to produce the cash flows resulting from its development, that each project rents only those assets it needs (including elements of goodwill) and not the ones that it does not need, and that each project pays the owner of the assets a fair return on (and of, when appropriate) the value of the rented assets. The customer relationship assets are being amortized on a straight-line basis (which approximates the economic pattern of benefits) over the estimated economic life of 10 years.

The goodwill recognized is attributable primarily to expected synergies from continuing operations of SCIO and the Company. The amount of goodwill recognized from SCIO's acquisition is not deductible for tax purposes. The goodwill has been assigned to our Analytics reportable segment based upon the Company’s assessment of nature of services rendered by SCIO.

Acquisition-related costs

Acquisition-related costs are being expensed as incurred and are included in general and administrative expenses in the unaudited consolidated statements of income. The Company recognized acquisition-related costs, which were incurred to effect business combination, for its SCIO and Health Integrated acquisitions of $nil and $363 during the three months ended March 31, 2019 and 2018, respectively.

Goodwill

The following table sets forth details of changes in goodwill by reportable segment of the Company:

	Insurance			Healthcare			TT&L			F&A			All Other		Analytics		Total
Balance at January 1, 2018	$	38,333		$	35,233		$	13,679		$	48,372		$	5,326	$	63,538	$	204,481

During the fourth quarter of 2018, the Company performed its annual impairment test of goodwill for all its reporting units. Based on the results, the fair values of each of the Company’s reporting units exceeded their carrying values except for the Health Integrated reporting unit, within the Healthcare operating segment. The primary factors contributing to a reduction in the fair value of the Health Integrated reporting unit were: (i) revenues and profitability in 2018 were significantly lower than the Company’s budget; and (ii) significant changes to the Company's estimated future cash flows and long-term growth assumptions for the Health Integrated reporting unit driven by loss of customer contracts, cost pressures and the Company’s most recent views of the long-term outlook for the Health Integrated business. As a result of this analysis, the Company recognized a goodwill impairment charge of $14,229 during the fourth quarter to write down the carrying value of Health Integrated’s goodwill to its fair value of $nil as of December 31, 2018. This impairment loss was recorded in the consolidated statements of income under "impairment charges".

As of March 31, 2019, the Company believes no other goodwill impairment exists, apart from the impairment charges discussed above, and that the remaining goodwill is recoverable for all of its reporting units; however, there can be no assurances that additional 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. It is reasonably possible that the judgments and estimates described above could change in future periods.

During the fourth quarter of 2018, the Company recognized impairment charges of $5,549 and $278 related to its customer relationships and trademarks intangible assets, respectively, in the Health Integrated reporting unit, within the Healthcare operating segment. The Company tested these intangible assets for recoverability due to indicators warranting the impairment test such as: (i) revenues and profitability in 2018 were significantly lower than the Company’s budget, and (ii) significant changes to the Company's estimated future cash flows and long-term growth assumptions for the Health Integrated reporting unit driven by loss of customer contracts, cost pressures and the Company’s most recent views of the long-term outlook for the Health Integrated business. Based on the results of its testing, the Company determined that the carrying value of the intangible assets was not

recoverable, and an impairment charge was recorded to the extent that carrying value exceeded estimated fair value. This impairment charge was recorded in the consolidated statements of income under "impairment charges". Subsequent to the impairment test, Health Integrated reporting unit’s customer relationships and trademarks intangibles assets were reduced to $nil as of December 31, 2018.

The remaining weighted average life of intangible assets is as follows:

	(in years)
Customer relationships	7.84

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 Note 17 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 accounts receivable, accounts payable and accrued expenses for which fair values approximate their carrying amounts due to their short-term nature.

Convertible Senior Notes:

The total estimated fair value of the convertible senior notes as of March 31, 2019 and December 31, 2018 was $137,374 and $130,510, respectively. The fair value was determined based on the market yields for similar Notes as of the March 31, 2019 and December 31, 2018. 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.

17. Derivatives and Hedge Accounting

The Company uses derivative instruments and hedging transactions to mitigate exposure to foreign currency fluctuation risks associated with forecasted transactions denominated in certain foreign currencies and to minimize earnings and cash flow volatility associated with changes in foreign currency 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 $410,189 (including $6,250 of range forward contracts) as of March 31, 2019 and $362,435 (including $6,900 of range forward contracts) as of December 31, 2018.

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) are recorded along with the underlying hedged item in the same line of unaudited consolidated statements of income as either part of “Cost of revenues”, “General and administrative expenses”, “Selling and marketing expenses”, “Depreciation and amortization”, as applicable.

The Company also enters into foreign currency forward contracts to economically hedge its intercompany balances and other monetary assets and liabilities denominated in currencies other than functional currencies. These derivatives do not qualify as fair value hedges under ASC 815. Changes in the fair value of these derivatives are recognized in the unaudited consolidated statements of income and are included in foreign exchange gain/(loss). The Company’s primary exchange rate exposure is with the Indian Rupee, the U.K. pound sterling and the Philippine peso. The Company also has exposure to Colombian pesos, Czech Koruna, the Euro, South African ZAR and other local currencies in which it operates. Outstanding foreign currency forward contracts amounted to $100,204 and GBP 12,767 as of March 31, 2019 and amounted to $125,503, GBP 15,616 and EUR 512 as of December 31, 2018.

The Company estimates that approximately $2,467 of net derivative gains, excluding tax effects, included in accumulated other comprehensive loss representing changes in the value of cash flow hedges, could be reclassified into earnings within the next twelve months based on exchange rates prevailing as of March 31, 2019. At March 31, 2019, the maximum outstanding term of the cash flow hedges was 45 months.

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.

18. Borrowings

Revolver Credit Agreement

On November 21, 2017, the Company and each of the Company’s wholly owned material domestic subsidiaries entered into a Credit Agreement with certain lenders, and Citibank, N.A. as Administrative Agent (the “Credit Agreement”). The Credit Agreement provides for a $200,000 revolving credit facility (the “Credit Facility”) with an option to increase the commitments by up to $100,000, subject to certain approvals and conditions as set forth in the Credit Agreement. The Credit Agreement also includes a letter of credit sub facility. The Credit Facility has a maturity date of November 21, 2022 and is voluntarily pre-payable from time to time without premium or penalty. Borrowings under the Credit Agreement may be used for working capital and general corporate purposes, including permitted acquisitions. On July 2, 2018, the Company exercised its option under the Credit Agreement to increase the commitments by $100,000 thereby utilizing the entire revolver under the Credit Facility of $300,000, to fund SCIO acquisition. The incremental commitments were made pursuant to (and constitute part of) the existing commitments and shall be subject to the terms and conditions applicable to the existing commitments as set forth in the Credit Agreement.

Depending on the type of borrowing, loans under the Credit Agreement bear interest at a rate equal to the specified prime rate (alternate base rate) or adjusted LIBO rate, plus, in each case, an applicable margin. The applicable margin is tied to the Company’s total net leverage ratio and ranges from 0% to 0.75% per annum with respect to loans pegged to the specified prime rate, and 1.00% to 1.75% per annum on loans pegged to the adjusted LIBO rate. The revolving credit commitments under the Credit Agreement are subject to a commitment fee, which is also tied to the Company’s total net leverage ratio, and ranges from 0.15% to 0.30% per annum on the average daily amount by which the aggregate revolving commitments exceed the sum of

29

EXLSERVICE HOLDINGS, INC.

NOTES TO UNAUDITED CONSOLIDATED FINANCIAL STATEMENTS—(continued)

(In thousands, except share and per share amounts)

outstanding revolving loans and letter of credit obligations. The Credit Facility carried an effective interest rate of 3.9% and 3.3% per annum during the three months ended March 31, 2019 and 2018.

Obligations under the Credit Agreement are guaranteed by the Company’s material domestic subsidiaries and are secured by all or substantially all of the assets of the Company and our material domestic subsidiaries. The Credit Agreement contains customary affirmative and negative covenants, including, but not limited to, restrictions on the ability to incur indebtedness, create liens, make certain investments, make certain dividends and related distributions, enter into, or undertake, certain liquidations, mergers, consolidations or acquisitions and dispose of assets or subsidiaries. In addition, the Credit Agreement contains a covenant to not permit the interest coverage ratio (the ratio of EBITDA to cash interest expense) or the total net leverage ratio (total funded indebtedness, less unrestricted domestic cash and cash equivalents not to exceed $50,000 to EBITDA) for the four consecutive quarter period ending on the last day of each fiscal quarter, to be less than 3.5 to 1.0 or more than 3.0 to 1.0, respectively. As of March 31, 2019, the Company was in compliance with all financial and non-financial covenants listed under the Credit Agreement.

The Company entered into a second amendment (the “Amendment”) to its Credit Agreement, as amended, among the Company, as borrower, with certain lenders, and Citibank, N.A. as Administrative Agent to, among other things, permit the issuance by the Company of the convertible notes, and settlement upon maturity or conversion thereof, in accordance with the Investment Agreement, the indenture dated as of October 4, 2018 and the other documents entered into in connection therewith.

As of March 31, 2019, the Company had outstanding indebtedness under the credit facility of $186,000, of which $20,000 is expected to be repaid within the next twelve months and is included under “current portion of long-term borrowings” and of which $166,000 is included under “long-term borrowings” in the unaudited consolidated balance sheets. As of December 31, 2018, the Company had an outstanding indebtedness under the credit facility of $150,000, of which $20,000 was included under “current portion of long-term borrowings,” and the balance of $130,000 was included under “long-term borrowings” in the consolidated balance sheets.

The Company incurred certain debt issuance costs, which are deferred and amortized as an adjustment to interest expense over the term of the credit facility. The unamortized debt issuance costs as of March 31, 2019 and December 31, 2018 was $942 and $1,006, respectively, and is included under "other current assets" and “other assets” in the unaudited consolidated balance sheets.

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 3.50% Convertible Senior Notes due October 1, 2024 (the “Notes”). The transactions contemplated by the Investment Agreement, including the issuance of the Notes, closed on October 4, 2018. The Notes bear interest at a rate of 3.50% per annum, payable semi-annually in arrears in cash on April 1 and October 1 of each year. During the three months ended March 31, 2019, the Company recognized interest expense of $1,313. The Notes are convertible at an initial conversion rate of 13.3333 shares of the common stock per $1,000 principal amount of the Notes (which represents an initial conversion price of approximately $75 per share). With certain exceptions, upon a fundamental change, as defined in the Indenture, the holders of the Notes may require that the Company to repurchase all or part of the principal amount of the Notes at a purchase price equal to the principal amount plus accrued and unpaid interest. The Company may 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 exceeds 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 may 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 Company used the proceeds from the issuance of Notes to repay $150,000 of its outstanding borrowings under the Credit Facility.

The net proceeds from the issuance of Notes were approximately $149,000, after deducting debt issuance costs of $1,000 and offering expenses of approximately $442 paid by the Company. These transaction and debt issuance costs were allocated between the liability and equity components based on their relative values. The transaction costs and debt issuance costs allocated to the liability and equity components were $1,279 and $163 respectively. The debt issuance costs allocated to the liability component are deferred and amortized as an adjustment to interest expense over the term of the Notes. The unamortized debt issuance costs

is presented as a direct reduction from the Notes in the unaudited consolidated balance sheets. The unamortized debt issuance costs as of March 31, 2019 and December 31, 2018 was $1,178 and $1,127, respectively.

The Company accounted for the liability and equity components of the Notes separately to reflect its non-convertible debt borrowing rate. The estimated fair value of the liability component at issuance of $133,077 was determined using a discounted cash flow technique, which considered debt issuances with similar features of the Company’s debt, excluding the conversion feature. The resulting effective interest rate for the Notes was 5.75% per annum. The excess of the gross proceeds received over the estimated fair value of the liability component totaling $16,923 was allocated to the conversion feature (equity component, recorded as additional paid-in capital) with a corresponding offset recognized as a discount to reduce the net carrying value of the Notes. The discount is being amortized to interest expense over a six-year period ending October 1, 2024 (the expected life of the liability component) using the effective interest method. During the three months ended March 31, 2019, the Company amortized $600 of the discount to interest expense. At the time of issuance, the Company evaluated the Notes in accordance with ASC 815-15 and determined that the Notes contain a single embedded derivative, being the call option having market interest rates as underlying, which does not require bifurcation as the features clearly and closely related to the host instrument. The Company determined that the value of this embedded derivative was nominal as of the date of issuance.

Borrowings also includes structured payables which are in the nature of debt, amounting to $1,542 and $2,114 as of March 31, 2019 and December 31, 2018, respectively, of which $876 and $1,423 is included under "current portion of long-term borrowings", $666 and $691, respectively, under "long-term borrowings" in the unaudited consolidated balance sheets.

Future principal payments/maturities for all of the Company's borrowings as of March 31, 2019 were as follows:

26. Commitments and Contingencies

Fixed Asset Commitments

At March 31, 2019, the Company has committed to spend approximately $9,552 under agreements to purchase property and equipment. This amount is net of capital advances paid in respect of these purchases.

Other Commitments

Certain units of the Company’s Indian subsidiaries were established as 100% Export-Oriented units or under the Software Technology Parks of India (“STPI”) scheme promulgated by the Government of India. These units are exempt from customs, central excise duties, and levies on imported and indigenous capital goods, stores, and spares. The Company has undertaken to pay custom duties, service taxes, levies, and liquidated damages payable, if any, in respect of imported and indigenous capital goods, stores and spares consumed duty free, in the event that certain terms and conditions are not fulfilled. The Company’s management believes, however, that these units have in the past satisfied and will continue to satisfy the required conditions.

The Company’s operations centers in the Philippines are registered with the Philippine Economic Zone Authority (“PEZA”). The registration provides the Company with certain fiscal incentives on the import of capital goods and requires ExlService Philippines, Inc. to meet certain performance and investment criteria. The Company’s management believes that these centers have in the past satisfied and will continue to satisfy the required criteria.

In March 2017, the Company was named as a defendant in a putative class action lawsuit filed in California, which challenged the classification of independent contractors. The parties participated in a mediation in early 2018. As the result of the mediation, a settlement was reached pursuant to which the Company agreed, without admission of wrongdoing, to pay a total of $2,400, of which $1,200 was paid in 2018 and the remainder has been paid during the three months ended March 31, 2019.

Contingencies

U.S. and Indian transfer pricing regulations require that any international transaction involving associated enterprises be at an arm’s-length price. Accordingly, the Company determines the appropriate pricing for the international transactions among its associated enterprises on the basis of a detailed functional and economic analysis involving benchmarking against transactions

among entities that are not under common control. The tax authorities have jurisdiction to review this arrangement and in the event that they determine that the transfer price applied was not appropriate, the Company may incur increased tax liability, including accrued interest and penalties. The Company is currently involved in disputes with the Indian tax authorities over the application of some of its transfer pricing policies for some of its subsidiaries. Further, the Company and a U.S. subsidiary are engaged in tax litigation with the income-tax authorities in India on the issue of permanent establishment. The Company is subject to taxation in the United States and various states and foreign jurisdictions. For the U.S. and India, tax year 2015 and subsequent tax years remain open for examination by the tax authorities as of March 31, 2019.

The aggregate amount demanded by Income tax authorities (net of advance payments, if any) from the Company related to its transfer pricing issues for tax years 2003 to 2014 and its permanent establishment issues for tax years 2003 to 2007 as of March 31, 2019 and December 31, 2018 is $17,863 and $18,177, respectively, of which the Company has made payments or provided bank guarantee to the extent $8,244 and $8,171, respectively. Amounts paid as deposits in respect of such assessments aggregating to $6,328 and $6,273 as of March 31, 2019 and December 31, 2018, respectively, are included in “Other assets” and amounts deposited for bank guarantees aggregating to $1,916 and $1,899 as of March 31, 2019 and December 31, 2018, respectively, are included in “Restricted cash” in the non-current assets section of the Company’s unaudited consolidated balance sheets.

Based on the facts underlying the Company’s position and its experience with these types of assessments, the Company believes that its position will more likely than not be sustained upon final examination by the tax authorities based on its technical merits as of the reporting date and accordingly has not accrued any amount with respect to these matters in its 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.

Executive Overview

We are an operations management and analytics company that helps businesses enhance revenue growth and improve profitability. Using proprietary platforms, methodologies, and our full range of digital capabilities, we look deeper to help companies transform their businesses, functions and operations, to help them deliver better customer experience and business outcomes, while managing risk and compliance. We serve our customers in the insurance, healthcare, travel, transportation and logistics, banking and financial services and utilities industries, among others.

We operate in the business process management (“BPM”) industry and we provide operations management and analytics services. Our eight operating segments are strategic business units that align our products and services with how we manage our business, approach our key markets and interact with our clients. Six of those operating segments provide BPM or “operations management” services, which we organize into industry-focused operating segments (Insurance, Healthcare, Travel, Transportation and Logistics, Banking and Financial Services, and Utilities) and one “capability” operating segment (Finance and Accounting) that provides services to clients in our industry-focused segments as well as clients across other industries. In each of these six operating segments we provide operations management services, which typically involve transfer to the Company of business operations of a client, after which we administer and manage those operations for our client on an ongoing basis. Our remaining two operating segments are Consulting, which provides industry-specific digital transformational services related to operations management services, and our Analytics operating segment, which provides services that focus on driving improved business outcomes for clients by generating data-driven insights across all parts of their business.

We present information for the following reportable segments:

• Insurance,

• Healthcare,

• Travel, Transportation and Logistics,

• Finance and Accounting,

• Analytics, and

• All Other (consisting of our remaining operating segments, including our Banking and Financial services, Utilities and Consulting operating segments).

Our global delivery network, which include 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 U.S., the Philippines, Bulgaria, Colombia, South Africa, Romania and the Czech Republic.

On July 1, 2018, we completed the acquisition of SCIO pursuant to the Merger Agreement. The acquisition of SCIO is included in the Analytics reportable segment. SCIO is a health analytics solution and services company serving over 100 healthcare organizations representing over 130 million covered lives across the continuum, including providers, health plans, pharmacy benefit managers, employers, health services and global life sciences companies.

On December 22, 2017, we acquired substantially all of the assets and assumed certain liabilities related thereto of Health Integrated. The acquisition of Health Integrated is included in the Healthcare reportable segment. Health Integrated provides dedicated care management services on behalf of health plans. Its services include case management, utilization management, disease management, special needs programs, and multichronic care management. Health Integrated serves lives in the Medicaid, Medicare, and dual eligible populations.

Revenues

For the three months ended March 31, 2019, we had revenues of $239.6 million compared to revenues of $207.0 million for the three months ended March 31, 2018, an increase of $32.6 million, or 15.8%.

We serve clients mainly in the U.S. and the U.K., with these two regions generating 81.9% and 12.1%, respectively, of our total revenues for the three months ended March 31, 2019, and 82.7% and 13.5%, respectively, of our revenues for the three months ended March 31, 2018.

For the three months ended March 31, 2019 and 2018, our total revenues from our top ten clients accounted for 38.4% and 39.6% of our total revenues, respectively. Our revenue concentration with our top clients remains 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 ten largest 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 U.S., Europe and Australia.

Operations Management Services: We provide our clients with a range of operations management services principally in the insurance, healthcare, travel, transportation and logistics, banking and financial services and utilities sectors, among others, as well as cross-industry operations management services, such as finance and accounting services. We also provide services related to operations management, through our Consulting services that provides industry-specific digital transformational services.

Our operations management solutions typically involve the transfer to the Company business operations of a client such as claims processing, clinical operations, or financial transaction processing, after which we administer and manage the operations for our client on an ongoing basis. As part of this transfer, we hire and train employees to 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 have been observing a shift in industry pricing models toward transaction-based pricing, outcome-based pricing and other pricing models. We believe this trend will continue and we have begun to use such alternative pricing models with some of our current clients and are seeking to move certain other clients from a billing rate model to a transaction-based or other pricing model. These pricing models place the focus on operating efficiency in order to maintain our gross margins. In addition, 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.

Our existing agreements with original terms of three or more years 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.

Analytics: Our Analytics services focus on driving improved business outcomes for our customers by generating data-driven insights 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 actively cross-sell and, where appropriate, integrate our Analytics services with other operations management services as part of a comprehensive offering set for our clients.

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

The following table summarizes our revenues by reportable segments for the three months ended March 31, 2019 and 2018:

	Three months ended March 31,							Percentage change
	2019		2018		Change
	(dollars in millions)
Insurance	$	69.0	$	63.9	$	5.1		8.0	%
Healthcare	20.6		22.8		(2.2		)	(9.8	)%
Travel, Transportation and Logistics	17.4		17.5		(0.1		)	(0.4	)%

Analytics	87.0		57.1		29.9			52.3	%
Total revenues, net	$	239.6	$	207.0	$	32.6		15.8	%

Revenues for the three months ended March 31, 2019 were $239.6 million, up $32.6 million, or 15.8%, compared to the three months ended March 31, 2018.

Revenue growth in Insurance of $5.1 million was primarily driven by expansion of business from our new and existing clients of $6.4 million. This was partially offset by $1.3 million mainly attributable to the depreciation of the Indian rupee and Australian dollar against the U.S. dollar during the three months ended March 31, 2019 compared to the three months ended March 31, 2018. Insurance revenues were 28.8% and 30.9% of our total revenues in the three months ended March 31, 2019 and March 31, 2018, respectively.

Revenue decline in Healthcare of $2.2 million was primarily driven by lower revenues from our Health Integrated business. Healthcare revenues were 8.6% and 11.0% of our total revenues in the three months ended March 31, 2019 and March 31, 2018, respectively.

Revenue decline in Travel, Transportation and Logistics ("TT&L") of $0.1 million was primarily driven by $0.3 million attributable to the depreciation of the Indian rupee and Philippine peso against the U.S. dollar during the three months ended March 31, 2019 compared to the three months ended March 31, 2018. This was partially offset by $0.2 million attributable to expansion of business from our existing clients. TT&L revenues were 7.3% and 8.5% of our total revenues in the three months ended March 31, 2019 and March 31, 2018, respectively.

Revenue growth in Finance and Accounting ("F&A") of $1.7 million was driven by net volume increases from our new and existing clients of $2.4 million. This was partially offset by $0.7 million mainly attributable to the depreciation of the Indian rupee against the U.S. dollar during the three months ended March 31, 2019 compared to the three months ended March 31, 2018. F&A revenues were 10.7% and 11.6% of our total revenues in the three months ended March 31, 2019 and March 31, 2018, respectively.

Revenue decline in All Other of $1.8 million was primarily driven by lower revenues of $0.8 million in our Banking and Financial Services operating segment and $0.3 million in our Consulting operating segment, partially offset by higher revenue of $0.1 million in our Utilities operating segment. Further decline of $0.8 million was due to the depreciation of the Indian rupee against the U.S. dollar and depreciation of U.K. pound sterling against the U.S. dollar. All Other revenues were 8.3% and 10.5% of our total revenues in the three months ended March 31, 2019 and March 31, 2018, respectively.

Revenue growth in Analytics of $29.9 million was primarily driven by our acquisition of SCIO in July 2018 contributing $19.1 million. The remaining increase of $11.3 million was attributable to our recurring- and project-based engagements from our new and existing clients. This was partially offset by $0.5 million attributable to the depreciation of the U.K. pound sterling against the U.S. dollar during the three months ended March 31, 2019 compared to the three months ended March 31, 2018. Analytics revenues were 36.3% and 27.6% of our total revenues in the three months ended March 31, 2019 and March 31, 2018, respectively.

Total	$	157.3	$	138.1	$	19.2		13.9	%	34.4	%	33.3	%	1.1	%

For the three months ended March 31, 2019, cost of revenues was $157.3 million compared to $138.1 million for the three months ended March 31, 2018, an increase of $19.2 million, or 13.9%. Our gross margin for the three months ended March 31, 2019 was 34.4% compared to 33.3% for three months ended March 31, 2018, an increase of 110 basis points (“bps”).

The increase in cost of revenues in Insurance of $4.3 million was primarily due to an increase in employee-related costs of $5.6 million on account of higher headcount and wage inflation, technology and infrastructure costs of $0.6 million, partially offset by lower other operating costs of $1.0 million and currency movements, net of hedging of $1.0 million. Gross margin in Insurance decreased by 120 bps during the three months ended March 31, 2019 compared to the three months ended March 31, 2018, primarily due to higher operating expenses associated with the initiation of services for new clients.

The decrease in cost of revenues in Healthcare of $0.2 million was primarily due to a decrease in infrastructure costs of $0.3 million and currency movements, net of hedging of $0.2 million, partially offset by higher employee-related costs of $0.3 million. Gross margin in Healthcare decreased by 700 bps during the three months ended March 31, 2019 compared to the three months ended March 31, 2018, primarily due to the impact of our Health Integrated business, lower revenues from existing clients and termination of certain client contracts.

The decrease in cost of revenues in TT&L of $0.7 million was primarily due to a decrease in infrastructure costs of $0.3 million and currency movements, net of hedging of $0.4 million. Gross margin in TT&L increased by 350 bps during the three months ended March 31, 2019 compared to the three months ended March 31, 2018, primarily due to higher volumes in existing clients.

The decrease in cost of revenues in F&A of $0.4 million was primarily due to a decrease in travel costs of $0.5 million, infrastructure costs of $0.2 million and currency movements, net of hedging of $0.2 million, partially offset by higher employee-related costs of $0.5 million on account of higher headcount and wage inflation. Gross margin in F&A increased by 590 bps during the three months ended March 31, 2019 compared to the three months ended March 31, 2018, primarily due to higher revenues from existing clients and higher margin in existing and new clients.

The decrease in cost of revenues in All Other of $2.6 million was primarily due to a decrease in employee-related costs of $1.3 million, travel and infrastructure costs of $0.8 million and currency movements, net of hedging of $0.5 million. Gross margin in All Other increased by 670 bps during the three months ended March 31, 2019 compared to the three months ended March 31, 2018, primarily due to lower operating costs in Utilities and Consulting operating segments.

The increase in cost of revenues in Analytics of $18.8 million was primarily due to an increase in employee-related costs of $15.3 million on account of higher headcount and wage inflation, including incremental cost related to our acquisition of SCIO in July 2018 of $10.1 million. The remaining increase was attributable to other operating costs of $4.3 million, partially offset by currency movements, net of hedging of $0.8 million. Gross margin in Analytics increased by 130 bps during the three months ended March 31, 2019 compared to the three months ended March 31, 2018, primarily due to higher gross margin from our SCIO acquisition.

Selling, General and Administrative (“SG&A”) Expenses.

	Three months ended March 31,						Change		Percentage change
	2019			2018
	(dollars in millions)
General and administrative expenses	$	32.5		$	29.2		$	3.3	11.2	%
Selling and marketing expenses	18.0			14.0			4.0		29.4	%
Selling, general and administrative expenses	$	50.5		$	43.2		$	7.3	17.0	%
As a percentage of revenues	21.1		%	20.9		%

The increase in SG&A expenses of $7.3 million was primarily due to an increase in employee-related costs of $7.6 million, including incremental costs related to our SCIO acquisition in July 2018 of $3.7 million, investment in new facilities $0.8 million, higher reserve for doubtful debts and other operating expenses of $2.0 million. This was partially offset by the recognition of a claim for litigation settlement of $2.4 million during the three months ended March 31, 2018 and currency movements net of hedging of $0.7 million.

Depreciation and Amortization.

	Three months ended March 31,						Change		Percentage change
	2019			2018
	(dollars in millions)
Depreciation expense	$	8.1		$	6.6		$	1.5	24.1	%

Depreciation and amortization expense	$	13.7		$	10.5		$	3.2	30.1	%
As a percentage of revenues	5.7		%	5.1		%

The increase in intangibles amortization expense of $1.7 million was primarily due to the increase in amortization of intangibles associated with our SCIO acquisition in July 2018. The increase in depreciation expense of $1.5 million was due to depreciation related to our new operating centers commenced during 2018 to support our business growth and depreciation associated with our SCIO acquisition.

Impairment Charges.

	Three months ended March 31,							Percentage change
	2019			2018		Change
	(dollars in millions)
Impairment charges	$	1.2		$	—	$	1.2	N/A
As a percentage of revenues	0.5		%	—

During the three months ended March 31, 2019, we performed an impairment test of our long-lived assets of our Health Integrated business. Based on the results, the long-lived assets carrying value exceeded their fair value. The primary factor contributing to a reduction in the fair value is the commencement of the wind down of the Health Integrated business, and an anticipated reduction to our estimated future cash flows. As a result of this analysis, we recognized a provisional impairment charge of $1.2 million during the three months ended March 31, 2019 to write down the carrying value of internally developed software to its fair value. See Note 8 to our unaudited consolidated financial statements for details.

Income from Operations. Income from operations increased by $1.7 million, or 11.3%, from $15.2 million for the three months ended March 31, 2018 to $16.9 million for the three months ended March 31, 2019. As a percentage of revenues, income from operations decreased from 7.3% for the three months ended March 31, 2018 to 7.0% for the three months ended March 31, 2019.

Foreign Exchange Gain/(Loss). Net foreign exchange gains and losses are primarily attributable to movement of the U.S. dollar against the Indian rupee, the U.K. pound sterling and the Philippine peso during the three months ended March 31, 2019. The average exchange rate of the U.S. dollar against the Indian rupee increased from 64.64 during the three months

45

ended March 31, 2018 to 70.32 during the three months ended March 31, 2019. The average exchange rate of the U.K. pound sterling against the U.S. dollar decreased from 1.40 during the three months ended March 31, 2018 to 1.32 during the three months ended March 31, 2019. The average exchange rate of the U.S. dollar against the Philippine peso increased from 51.85 during the three months ended March 31, 2018 to 52.11 during the three months ended March 31, 2019.

We recorded a net foreign exchange gain of $1.3 million for the three months ended March 31, 2019 compared to the net foreign exchange gain of $0.6 million for the three months ended March 31, 2018.

Interest expense. Interest expense increased from $0.5 million for the three months ended March 31, 2018 to $3.6 million for the three months ended March 31, 2019 primarily due to increase in borrowings under our Credit Facility, issuance of convertible notes and higher effective interest rates.

Other Income, net.

	Three months ended March 31,						Percentage change
	2019		2018		Change
	(dollars in millions)

Other, net	0.1		0.1		—		8.6	%
Other income, net	$	4.4	$	3.5	$	0.9	25.2	%

Other income, net increased by $0.9 million, from $3.5 million for the three months ended March 31, 2018 to $4.4 million for the three months ended March 31, 2019, primarily due to a higher return on our mutual fund investments of $0.4 million and an increase in interest and dividend income of $0.5 million during the three months ended March 31, 2019 compared to three months ended March 31, 2018.

Income Tax Expense. We recorded income tax expense of $4.2 million and income tax benefit of $4.5 million for the three months ended March 31, 2019 and 2018, respectively. The effective tax rate increased from (23.7%) during the three months ended March 31, 2018 to 22.1% during the three months ended March 31, 2019 primarily as a result of (i) an adjustment of $4.8 million reducing the provisional transition tax on the mandatory deemed repatriation of accumulated earnings and profits ("E&P") of foreign subsidiaries recognized during the three months ended March 31, 2018 (ii) recording of excess tax benefits related to stock awards of $4.8 million pursuant to ASU No. 2016-09 during the three months ended March 31, 2018 compared to $1.0 million during the three months ended March 31, 2019. See Note 22 to our unaudited consolidated financial statements.

Net Income. Net income decreased from $23.2 million for the three months ended March 31, 2018 to $14.7 million for the three months ended March 31, 2019, primarily due to higher income tax expense of $8.7 million, higher interest expense of $3.1 million, partially offset by increase in income from operations of $1.7 million, other income, net of $0.9 million and higher foreign exchange gain of $0.7 million. As a percentage of revenues, net income decreased from 11.2% for the three months ended March 31, 2018 to 6.1% for the three months ended March 31, 2019.

Liquidity and Capital Resources

	Three months ended March 31,

	(dollars in millions)
Opening cash, cash equivalents and restricted cash	$	104.1		$	94.3
Net cash provided by/(used for) operating activities	8.3			(8.0		)
Net cash used for investing activities	(37.2		)	(3.0		)
Net cash provided by/(used for) financing activities	19.8			(6.2		)
Effect of exchange rate changes	(0.4		)	(0.6		)
Closing cash, cash equivalents and restricted cash	$	94.6		$	76.5

As of March 31, 2019 and 2018, we had $302.7 million and $280.4 million, respectively, in cash, cash equivalents and short-term investments. During the first quarter of 2018, we made an election to change the tax status of most of our controlled foreign corporations ("CFC") to disregarded entities for U.S. income tax purposes. As a result, we no longer have undistributed earnings in connection with our CFCs. The transition tax resulted in previously taxed income ("PTI") which may be subject to withholding taxes and currency gains or losses upon repatriation. We presently do not intend to distribute our PTI and have not recorded any deferred taxes. If, in the future, we change our present intention regarding the distribution of PTI, additional taxes may be required and would be recorded in the period the intention changes.

Operating Activities: Cash flows provided by operating activities were $8.3 million for the three months ended March 31, 2019 as compared to cash flows used for operating activities of $8.0 million during the three months ended March 31, 2018. Generally, factors that affect our earnings—including pricing, volume of services, costs and productivity—affect our cash flows used or provided from operations in a similar manner. However, while management of working capital, including timing of collections and payments affects operating results only indirectly, the impact on the working capital and cash flows provided by operating activities can be significant.

Cash flows provided by operating activities for the three months ended March 31, 2019 was $8.3 million. This comprised of net income plus the net effect of non-cash items, such as depreciation and amortization, stock-based compensation expense, deferred income taxes, impairment charges and others aggregating to $36.0 million. The primary working capital use of cash of $37.7 million during the three months ended March 31, 2019 was driven by an increase in accounts receivables, accrued employee costs, advance income tax and accounts payables. The primary working capital sources of cash of $10.0 million was driven by higher accrued expenses and other liabilities and deferred revenue.

Investing Activities: Cash flows used for investing activities were $37.2 million for the three months ended March 31, 2019 as compared to cash flows used for investing activities of $3.0 million for the three months ended March 31, 2018. The increase is mainly due to net purchase of investments of $26.3 million during the three months ended March 31, 2019 as compared to net proceeds from investments of $10.0 million during the three months ended March 31, 2018, partially offset by lower capital expenditures of $1.8 million during the three months ended March 31, 2019 compared to the three months ended March 31, 2018.

Financing Activities: Cash flows provided by financing activities were $19.8 million during the three months ended March 31, 2019 as compared to cash flows used for financing activities of $6.2 million during the three months ended March 31, 2018. The increase in cash flows provided by financing activities was primarily due to higher net borrowings of $28.5 million (net of repayments) under our Credit Facility (as described below in “Financing Arrangements”) during the three months ended March 31, 2019, partially offset by higher purchases of treasury stock by $1.9 million under our share repurchase program during the three months ended March 31, 2019.

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, and purchase telecommunications equipment and computer hardware and software in connection with managing client operations. We incurred $10.9 million of capital expenditures in the three months ended March 31, 2019. We expect to incur capital expenditures of between $35.0 million to $40.0 million in 2019, 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 26 to our unaudited consolidated

47

financial statements herein for further details). We anticipate that we will continue to rely upon cash from operating activities to finance our smaller acquisitions, capital expenditures and working capital needs. If we have significant growth through acquisitions, we may need to obtain additional financing.

Financing Arrangements (Debt Facility)

Revolver Credit Agreement

On November 21, 2017, we and each of our wholly owned material domestic subsidiaries entered into a Credit Agreement with certain lenders, and Citibank, N.A. as Administrative Agent (the “Credit Agreement”). The Credit Agreement provides for a $200.0 million revolving credit facility (the “Credit Facility”) with an option to increase the commitments by up to $100.0 million, subject to certain approvals and conditions as set forth in the Credit Agreement. The Credit Agreement also includes a letter of credit sub facility. The Credit Facility has a maturity date of November 21, 2022 and is voluntarily pre-payable from time to time without premium or penalty. Borrowings under the Credit Agreement may be used for working capital and general corporate purposes, including permitted acquisitions. On July 2, 2018, we exercised our option under the Credit Agreement to increase the commitments by $100.0 million thereby utilizing the entire revolver under the Credit Facility of $300.0 million, to fund the SCIO acquisition. The incremental commitments were made pursuant to (and constitute part of) the existing commitments and shall be subject to the terms and conditions applicable to the existing commitments as set forth in the Credit Agreement.

We entered into a second amendment (the “Amendment”) to our Credit Agreement, as amended, among the Company, as borrower, with certain lenders, and Citibank, N.A. as Administrative Agent to, among other things, permit the issuance by us of the convertible notes, and settlement upon maturity or conversion thereof, in accordance with the Investment Agreement, the indenture dated as of October 4, 2018 and the other documents entered into in connection therewith.

See Note 18 to our unaudited consolidated financial statements herein for further details on our debt facilities.

As of March 31, 2019, we had outstanding indebtedness under the credit facility of $186.0 million, of which $20.0 million is expected to be repaid within the next twelve months and is included under “current portion of long-term borrowings” and of which $166.0 million is included under “long-term borrowings” in the unaudited consolidated balance sheets. As of December 31, 2018, we had outstanding indebtedness under the credit facility of $150.0 million, of which $20.0 million was presented under "current portion of long-term borrowings" and the balance of $130.0 million was included under "long-term borrowings" in the unaudited consolidated balance sheets.

Convertible Senior Notes

On October 1, 2018, we 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 $150.0 million in an aggregate principal amount of 3.50% Convertible Senior Notes due October 1, 2024 (the "Notes"). The transactions contemplated by the Investment Agreement, including the issuance of the Notes, closed on October 4, 2018. The Notes bear interest at a rate of 3.50% per annum, payable semi-annually in arrears in cash on April 1 and October 1 of each year. During the three months ended March 31, 2019, we recognized interest expense of $1.3 million. The Notes are convertible at an initial conversion rate of 13.3333 shares of the common stock per $1,000 principal amount of the Notes (which represents an initial conversion price of approximately $75 per share). With certain exceptions, upon a fundamental change, as defined in the Indenture, the holders of the Notes may require us to repurchase all or part of the principal amount of the Notes at a purchase price equal to the principal amount plus accrued and unpaid interest. We may redeem the principal amount of the Notes, at our 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 exceeds 150% of the then-current conversion price for 20 or more trading days in the 30 consecutive trading day period preceding our exercise of this redemption right (including the trading day immediately prior to the date of the notice of redemption). We may elect to settle conversions of the Notes by paying or delivering, as the case may be, cash, shares of our common stock or a combination of cash and shares of our common stock. We used the proceeds from the issuance of Notes to repay $150.0 million of our outstanding borrowings under the Credit Facility.

We accounted for the liability and equity components of the Notes separately to reflect its non-convertible debt borrowing rate. The estimated fair value of the liability component at issuance of $133.1 million was determined using a discounted cash flow technique, which considered debt issuances with similar features of our debt, excluding the conversion feature. The

48

resulting effective interest rate for the Notes was 5.75% per annum. The excess of the gross proceeds received over the estimated fair value of the liability component totaling $16.9 million, excluding tax effects, was allocated to the conversion feature (equity component, recorded as additional paid-in capital) with a corresponding offset recognized as a discount to reduce the net carrying value of the Notes. The discount is being amortized to interest expense over a six-year period ending October 1, 2024 (the expected life of the liability component) using the effective interest method.

Under the terms of the Notes, we are not prohibited from paying cash dividends unless payment would trigger an event of default or if one currently exists. We do not anticipate paying any cash dividends in the foreseeable future.

Off-Balance Sheet Arrangements

As of March 31, 2019, we had no off-balance sheet arrangements or obligations.

(a) Represents minimum lease payments payable for cancellable and non-cancellable lease period.

(b) Represents estimated payments under the Gratuity Plan.

(c) Interest on borrowings is calculated based on the interest rate on the outstanding borrowings as of March 31, 2019.

(d) Excludes $0.8 million related to uncertain tax positions, since the extent of the amount and timing of payment is currently not reliably estimable or determinable.

Certain units of our Indian subsidiaries were established as 100% Export-Oriented units under the “STPI” scheme promulgated by the Government of India. These units are exempt from customs, central excise duties, and levies on imported and indigenous capital goods, stores, and spares. 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 “PEZA.” The registration provides us with certain fiscal incentives on the import of capital goods and requires that ExlService Philippines, Inc. meet certain performance and investment criteria. We believe that these centers have in the past satisfied and will continue to satisfy the required criteria.

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 our 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 March 31, 2019. Based upon that evaluation, the CEO and CFO have concluded that, as of March 31, 2019, our disclosure controls and procedures were effective.

During the three months ended March 31, 2019, there was no change in our internal control over financial reporting (as defined in Rules 13a-15(f) and 15d-15(f) under the Exchange Act) that has materially affected, or is reasonably likely to materially affect, our internal control over financial reporting.

In making its assessment of the changes in internal control over financial reporting during the three months ended March 31, 2019, our management excluded an evaluation of the disclosure controls and procedures of SCIO which we acquired on July 1, 2018.

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 (“US 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 US 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, 2018.

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 income and expenses arising from intra-group transactions, are eliminated while preparing those 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 US GAAP.

The Company’s investments in equity affiliates are initially recorded at cost and any excess cost 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 is recognized in the unaudited consolidated statements of income.

Non-controlling interest is the equity in a subsidiary not attributable, directly or indirectly, to the parent and it represents the minority partner’s interest in the operations of ExlService Colombia S.A.S. Non-controlling interest consists of the amount of such interest at the date of obtaining control over the subsidiary, and the non-controlling interest's share of changes in equity since that date. The non-controlling interest in the operations for all periods presented were insignificant and is included under general and administrative expenses in the unaudited consolidated statements of income.

(b) Use of Estimates

The preparation of the unaudited consolidated financial statements in conformity with US GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the 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 financial statements include, but are not limited to, allowance for doubtful receivables, expected recoverability from customers with contingent fee arrangements, 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 incremental borrowing rate to calculate lease liabilities and right-of-use (“ROU”) assets, lease term to calculate lease cost, depreciation and amortization periods,

purchase price allocation, recoverability of long-lived assets including goodwill and intangibles, and estimated costs to complete fixed price contracts.

(c) Employee Benefits

Contributions to defined contribution plans are charged to the unaudited consolidated statements of income in the period in which services are rendered by the covered employees. Current service costs for defined benefit plans are accrued in the period to which they relate. The liability in respect of defined benefit plans is calculated annually by the Company using the projected unit credit method. Prior service cost, if any, resulting from an amendment to a plan is recognized and amortized over the remaining period of service of the covered employees.

The Company recognizes its liabilities for compensated absences depending on whether the obligation is attributable to employee services already rendered, relates to rights that vest or accumulate and payment is probable and estimable.

The Company includes the service cost component of the net periodic benefit cost in the same line item or items as other compensation costs arising from services rendered by the respective employees during the period. The interest cost, expected return on plan assets and amortization of actuarial gains/loss are classified in “Other income, net”. Refer Note 20 to the unaudited consolidated financial statements for details.

(d) Cash and Cash Equivalents and Restricted Cash

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

Restricted cash represents amounts on deposit with banks against bank guarantees issued through banks in favor of relevant statutory authorities for equipment imports, deposits for obtaining indirect tax registrations and for demands against pending income tax assessments (refer Note 26 to the unaudited consolidated financial statements for details). These deposits with banks have maturity dates after March 31, 2020. Restricted cash presented under current assets represents funds held on behalf of clients in dedicated bank accounts.

For purposes of the unaudited statements of cash flows, the Company includes in its cash and cash-equivalent balances those amounts that have been classified as restricted cash and restricted cash equivalents.

(e) Revenue Recognition

Revenue is recognized when services are provided to our customers, in an amount that reflects the consideration we expect to be entitled to in exchange for our services.

Revenue is measured based on consideration specified in a contract with a customer and excludes discounts and amounts collected on behalf of third parties. The Company recognizes revenue when it satisfies a performance obligation by providing services to a customer.

Taxes assessed by a governmental authority that are both imposed on and concurrent with a specific revenue-producing transaction, that are collected by the Company from a customer, are excluded from revenue.  

Adoption of ASU 2014-09 Topic 606, “Revenue from Contracts with Customers” (Topic 606)

On January 1, 2018, the Company adopted Topic 606 using the modified retrospective method and applied its guidance to those contracts which were not completed as of January 1, 2018. Results for reporting periods beginning after January 1, 2018 are presented under Topic 606. The effect from the adoption of Topic 606 was not material to the Company's financial statements.

Nature of services

The Company derives its revenues from operations management and analytics services. The Company operates in the business process management (“BPM”) industry providing operations management and analytics services helping businesses enhance revenue growth and improve profitability. The Company provides BPM or “operations management” services, which typically involve transfer to the Company of business operations of a client, after which it administers and manages those operations for its client on an ongoing basis. The Company also provides industry-specific digital transformational services related to operations management services, and analytics services that focus on driving improved business outcomes for clients by generating data-driven insights across all parts of their business. The Company also provides care optimization and reimbursement optimization

services, for its clients through its healthcare analytics solutions and services. The Company offers integrated solutions to help its clients with cost containment by leveraging technology platforms, customizable and configurable analytics and expertise in healthcare reimbursements to help clients enhance their claims payment accuracy.

Type of Contracts

i. a) Revenues under time-and-material, transaction and outcome-based contracts are recognized as the services are performed. When the terms of the client contract specify service level parameters that must be met (such as turnaround time or accuracy), the Company monitors such service level parameters to determine if any service credits or penalties have been incurred. Revenues are recognized net of any penalties or service credits that are due to a client.

b) In respect of arrangements involving subcontracting, in part or whole of the assigned work, the Company evaluates whether it is in control of the services before the same are transferred to the customer to assess whether it is Principal or Agent in the arrangement based on guidance on “Principal versus agent considerations” in Topic 606.

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

iii. Revenues from the Company's software and related services contracts, which are not significant, are primarily related to maintenance renewals or incremental license fees for additional users. Maintenance revenues are generally recognized on a straight-line basis over the annual contract term. Fees for incremental license without any associated services are recognized upon delivery of the related incremental license. To a lesser extent, software and related services contracts may contain software license, related services and maintenance elements as a multiple element arrangement. In such cases, revenue is allocated to maintenance based on the price charged when that element is sold separately.

iv. Revenues from reimbursement optimization services having contingent fee arrangements are recognized by the Company at the point in time when a performance obligation is satisfied, which is when it identifies an overpayment claim and the same is acknowledged by its customers. In such contracts, the Company’s consideration is contingent upon the actual collections made by its customers and subsequent potential retraction claims. Based on guidance on “variable consideration” in Topic 606, the Company uses its historical experience and projections to determine the expected recoveries from its customers and recognizes revenue based upon such expected recoveries. Any adjustment required due to change in estimates are recorded in the period in which such change is identified.

Arrangements with Multiple Performance Obligations

The Company’s contracts with customers do not generally bundle different services together except for software and related services contracts, which are not significant, involving implementation services and post contract maintenance services. In such software and related services contracts, revenue is allocated to each performance obligation based on the relative standalone selling price.

A separate contract is generally drafted for each type of service sold, even if to the same customer. The typical length of a contract is 3 to 5 years for our operations management contracts.

Allocation of transaction price to performance obligations

The transaction price is allocated to performance obligations on a relative standalone selling price basis. Standalone selling prices are estimated by reference to the total transaction price less the sum of the observable standalone selling prices of other goods or services promised in the contract.  In assessing whether to allocate variable consideration to a specific part of the contract,

the Company considers the nature of the variable payment and whether it relates specifically to its efforts to satisfy a specific part of the contract.

Variable Consideration

Variability in the transaction price arises primarily due to service level agreements, cost of living adjustments, and pre-payment and volume discounts.

The Company considers its experience with similar transactions and expectations regarding the contract in estimating the amount of variable consideration that should be recognized during a period.

The Company believes that the expected value method is most appropriate for determining the variable consideration since the company has large number of contracts with similar nature of transactions/services.

Unbilled Receivables

Unbilled receivables represents revenues recognized for services rendered between the last billing date and the balance sheet date. Unbilled receivables also include revenues recognized from reimbursement optimization services when the Company identifies an overpayment claim and the same is acknowledged by its customers, however not invoiced at the balance sheet date. Accordingly, amounts for services that the Company has performed and for which an invoice has not yet been issued to the customers are presented as a part of contract assets as accounts receivable.

Deferred Revenue

The Company has deferred revenue attributable to certain process transition activities, with respect to its customers where such activities do not represent separate performance obligations. Revenues related to such transition activities are contract liabilities classified under “Deferred Revenue” in the Company's unaudited consolidated balance sheets and subsequently recognized ratably over the period in which the related services are performed. Deferred revenue also includes the amount for which services have been rendered but other conditions of revenue recognition are not met, for example where the Company does not have persuasive evidence of an arrangement with customer. Costs related to such transition activities are contract fulfillment costs, and thereby classified under “Other Current Assets” and “Other Assets” in the unaudited consolidated balance sheets, and are recognized ratably over the estimated expected period of benefit, under Cost of Revenues in the unaudited consolidated statements of income.

Other incremental and direct costs incurred for acquiring contracts, such as sales commissions are contract acquisition costs and thereby classified under “Other Current Assets” and “Other Assets” in the unaudited consolidated balance sheets. Such costs are amortized over the expected period of benefit and recorded under Selling and marketing expenses in the unaudited consolidated statements of income.

Any upfront payments made to customers are contract assets and classified under “Other Current Assets and Other Assets” in the unaudited consolidated balance sheets. Such costs are amortized over the expected period of benefit and are recorded as an adjustment to transaction price and reduced from revenues.

Reimbursements of out-of-pocket expenses received from clients are included as part of revenues.

Payment terms

All Contracts entered into by the Company specify the payment terms and are defined for each contract separately. Usual payment terms range between 30-60 days. The Company does not have any extended payment terms clauses in existing contracts. At times, the Company enters into fixed price contracts and software licenses involving significant implementation wherein the milestones are defined such that the Company can recover the costs with a reasonable margin.

Practical expedients and exemptions

The Company does not disclose the value of unsatisfied performance obligations for (i) contracts with an original expected length of 1 year or less and (ii) contracts for which the Company recognizes revenue at the amount to which we have the right to invoice for services performed.

Accounts Receivable

We record accounts receivable net of allowances for doubtful accounts. Allowances for doubtful accounts are established through the evaluation of aging of accounts receivables, prior collection experience, current market conditions, clients’ financial condition and the amount of accounts receivables in dispute to estimate the collectability of these accounts receivables.

(f) Leases

The Company determines if an arrangement is a lease at inception. Operating leases are included in operating lease right-of-use ("ROU") assets, current portion of operating lease liabilities and operating lease liabilities, less current portion in the Company's unaudited consolidated balance sheets. Finance leases are included in property and equipment, current portion of finance lease obligations and finance lease obligations, less current portion in the Company's unaudited consolidated balance sheets.

ROU assets represent the Company’s right to use an underlying asset for the lease term and lease liabilities represent the Company’s obligation to make lease payments arising from the lease. Operating lease ROU assets and liabilities are recognized at commencement date based on the present value of lease payments over the lease term. For leases in which the rate implicit in the lease is not readily determinable, the Company uses its incremental borrowing rate based on the information available at commencement date in determining the present value of lease payments. Lease terms include options to extend or terminate the lease when it is reasonably certain that the Company will exercise that option. Lease expense for operating lease arrangements is recognized on a straight-line basis over the lease term. The Company has lease agreements with lease and non-lease components, which are accounted for separately.

On January 1, 2019, the date of initial application, the Company adopted, Leases (Topic 842), using the modified retrospective method. The modified retrospective method provides a method of recording those leases which had not expired as of the date of adoption of January 1, 2019. The prior period unaudited consolidated financial statements have not been retrospectively adjusted and continues to be reported under Topic 840.

The Company elected the practical expedient permitted under the transition guidance under Topic 842, which amongst other matters, allowed the Company (i) not to apply the recognition requirements to short-term leases (leases with a lease term of 12 months or less), (ii) not to reassess whether any expired or existing contracts are or contain leases, (iii) not to reassess the lease classification for any expired or existing leases, and (iv) not to reassess initial direct costs for any existing leases.

The adoption resulted in the recognition of ROU assets of $80,328, net of deferred rent of $8,626 and lease liabilities of $88,954 for operating leases as of January 1, 2019. The Company's accounting for finance leases remained substantially unchanged. The adoption had no impact on opening balance of retained earnings.

Refer Note 21 to the unaudited consolidated financial statements for details.

(g) Recent Accounting Pronouncements    

In June 2016, the Financial Accounting Standards Board ("FASB") issued ASU No. 2016-13, Financial Instruments - Credit Losses, which requires a financial asset (or a group of financial assets) measured at amortized cost basis to be presented at the net amount expected to be collected. The allowance for credit losses is a valuation account that is to be deducted from the amortized cost of the financial asset(s) so as to present the net carrying value at the amount expected to be collected on the financial asset. The new guidance is effective for fiscal years beginning after December 15, 2019, including interim periods within those fiscal years. The amendment should be applied through a modified retrospective approach. Early adoption as of the fiscal years beginning

after December 15, 2018 is permitted. The Company is currently evaluating the impact that the adoption of this guidance will have on its consolidated financial statements.

In June 2018, FASB issued ASU No. 2018-07, Compensation-Stock Compensation (Topic 718): Improvements to Non-employee Share-Based Payment Accounting. This ASU involves several aspects of the accounting for non-employee share-based payment transactions resulting from expanding the scope of Topic 718, Compensation-Stock Compensation, to include share-based payment transactions for acquiring goods and services from non-employees. The amendments in this ASU affect all entities that enter into share-based payment transactions for acquiring goods and services from non-employees. This ASU is effective for public business entities for fiscal years beginning after December 15, 2018, including interim periods within that fiscal year.  Early adoption is permitted, but no earlier than an entity’s adoption date of Topic 606. The adoption of this ASU is not expected to have any material effect on the Company’s consolidated financial statements.

In August 2018, FASB issued ASU No. 2018-13, Fair Value Measurement (Topic 820): Changes to the Disclosure Requirements for Fair Value Measurement. The amendments in this ASU modify the disclosure requirements on fair value measurements in Topic 820, based on the concepts in the Concepts Statement, including the consideration of costs and benefits. The amendments in ASU are effective for fiscal years beginning after December 15, 2019, including interim periods within those fiscal years. An entity is permitted to early adopt either the entire standard or only the provisions that eliminate or modify requirements. The adoption of this ASU is not expected to have any material effect on the Company’s consolidated financial statements.

In August 2018, FASB issued ASU No. 2018-14, Compensation-Retirement Benefits-Defined Benefit Plans-General (Subtopic 715-20): Changes to the Disclosure Requirements for Defined Benefit Plans. The amendments in this Update remove disclosures that no longer are considered cost beneficial, clarify the specific requirements of disclosures, and add disclosure requirements identified as relevant. The amendments in ASU are effective for fiscal years beginning after December 15, 2020. An entity is permitted to early adopt this Update. The adoption of this ASU is not expected to have any material effect on the Company’s consolidated financial statements.

In August 2018, FASB issued ASU No. 2018-15, Intangibles - Goodwill and Other - Internal-Use Software (Subtopic 350-40): This ASU aligns the requirements for capitalizing implementation costs incurred in a hosting arrangement that is a service contract with the requirements for capitalizing implementation costs incurred to develop or obtain internal-use software (and hosting arrangements that include an internal-use software license). Accordingly, the ASU requires an entity (customer) in a hosting arrangement that is a service contract to follow the guidance in FASB Accounting Standard Codification Subtopic 350-40 on internal-use software to determine which implementation costs to capitalize as an asset related to the service contract and which costs to expense. The ASU 2018-15 also provides guidance on amortization and impairment of any costs capitalized, along with new presentation and disclosure requirements. The new guidance is effective for fiscal years beginning after December 15, 2019.  Early adoption is permitted and both prospective and retrospective transition methods are allowed. The Company is currently evaluating the impact that the adoption of this guidance will have on its consolidated financial statements.

(h) Recently Adopted Accounting Pronouncements

In February 2016, FASB issued ASU No. 2016-02, Leases (Topic 842), which requires the identification of arrangements that should be accounted for as leases. Lease arrangements exceeding a twelve months term should be recognized as assets with corresponding liabilities on the balance sheet of the lessee. This ASU requires recognition of an ROU asset and lease obligation for those leases classified as operating leases under Topic 840, while the income statement will reflect lease expense for operating leases. The balance sheet amounts recorded for existing operating leases at the date of adoption of this ASU must be calculated using the applicable incremental borrowing rate. The Company adopted Topic 842 as of January 1, 2019 using the modified retrospective method provided by ASU 2018-11. The adoption had a material impact on the Company's unaudited consolidated balance sheets, but did not have a material impact on the Company's unaudited consolidated income statements and unaudited consolidated statements of cash flows. The most significant impact was the recognition of ROU assets and lease liabilities for operating leases, while the Company's accounting for finance leases remained substantially unchanged. Refer Note 21 to the unaudited consolidated financial statements for details.

In July 2018, FASB issued ASU No. 2018-11, Leases (Topic 842), which provide entities with an additional (and optional) transition method to adopt the new leases standard. Under this new transition method, an entity initially applies the new leases standard at the adoption date and recognizes a cumulative-effect adjustment to the opening balance of retained earnings in the period of adoption. Consequently, an entity’s reporting for the comparative periods presented in the financial statements in which

it adopts the new leases standard will continue to be in accordance with current GAAP (Topic 840, Leases). The Company adopted Topic 842 as of January 1, 2019 using this ASU. Refer Note 21 to the unaudited consolidated financial statements for details.

Segment Reporting [Abstract]

Segment and Geographical Information

Segment and Geographical Information

The Company operates in the BPM industry and is a provider of operations management and analytics services. The Company has eight operating segments, which are strategic business units that align its products and services with how it manages its business, approaches its key markets and interacts with its clients. Six of those operating segments provide BPM or “operations management” services, five of which are industry-focused operating segments (Insurance, Healthcare, Travel, Transportation and Logistics, Banking and Financial Services, and Utilities) and one of which is a “capability” operating segment (Finance and Accounting) that provides services to clients in our industry-focused segments as well as clients across other industries. In each of these six operating segments, the Company provides operations management services, which typically involve transfer to the Company of the business operations of a client, after which it administers and manages those operations for its client on an ongoing basis. The remaining two operating segments are Consulting, which provides industry-specific transformational services related to operations management services, and Analytics, which provides services that focus on driving improved business outcomes for clients by generating data-driven insights across all parts of their business.

The Company presents information for the following reportable segments:

• Insurance

• Healthcare

• Travel, Transportation and Logistics (“TT&L”)

• Finance and Accounting (“F&A”)

• Analytics, and

• All Other (consisting of the Company's remaining operating segments, which are the Banking and Financial Services, Utilities and Consulting operating segments).

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 other 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 March 31, 2019 and 2018, respectively, for each of the reportable segments, are as follows:

Earnings Per Share [Abstract]

Earnings Per Share

Earnings Per Share

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

During the three months ended March 31, 2019, the Company performed an impairment test of its long-lived assets of its Health Integrated business. Based on the results, the long-lived assets carrying value exceeded their fair value. The primary factor contributing to a reduction in the fair value is the commencement of the wind down of the Health Integrated business, and an anticipated reduction to the Company's estimated future cash flows. As a result of this analysis, the Company recognized a provisional impairment charge of $1,227 during the three months ended March 31, 2019 to write down the carrying value of internally developed software to its fair value. This impairment loss was recorded in the unaudited consolidated statements of income under "impairment charges".

Business Combinations, Goodwill and Intangible Assets

SCIOinspire Holdings Inc.

On July 1, 2018, the Company, through its wholly owned subsidiary ExlService.com, LLC (“Buyer”) and Buyer’s wholly owned subsidiary, ExlService Cayman Merger Sub, completed the acquisition of SCIO pursuant to an Agreement of Merger dated April 28, 2018 (the "Merger Agreement"). ExlService Cayman Merger Sub, merged with and into SCIO, with SCIO surviving the merger as a wholly-owned subsidiary of the Buyer.

SCIO is a health analytics solution and services company serving healthcare organizations including providers, health plans, pharmacy benefit managers, employers, health services and global life sciences companies. The acquisition is expected to significantly strengthen the Company’s capability in the high growth cost optimization and care optimization markets. The acquisition of SCIO is included in the Analytics reportable segment.

The aggregate purchase consideration was $245,044, including cash and cash equivalents acquired and post-closing adjustments. The aggregate base purchase consideration payable at closing of the merger was $236,500 based on completion of diligence, which was adjusted based on, among other things, SCIO’s cash, debt, working capital position and other adjustments as of the Closing as set forth in the Merger Agreement. To finance the acquisition at Closing, the Company utilized its revolving Credit Facility in the amount of $233,000, issued 69,459 shares of restricted common stock of the Company in the amount of $4,080 and paid the balance with available cash on hand.

Pursuant to the Company’s business combinations accounting policy, the total purchase consideration for SCIO was allocated to identifiable net tangible and intangible assets based upon their preliminary fair values. The excess of the purchase consideration over fair value of identifiable net tangible and intangible assets was recorded as goodwill. In order to allocate the consideration transferred for SCIO, the fair values of all identifiable assets and liabilities were established. For accounting and financial reporting

purposes, fair value is defined under ASC No. 820, Fair Value Measurement and Disclosure, as the price that would be received upon sale of an asset or the amount paid to transfer a liability in an orderly transaction between market participants at the measurement date. Market participants are assumed to be buyers and sellers in the principal (most advantageous) market for the asset or liability. Additionally, fair value measurements for an asset assume the highest and best use of that asset by market participants. Use of different estimates and judgments could yield different results.

The fair value of assets acquired and liabilities assumed from the acquisition of SCIO is based on a preliminary valuation. The primary areas of the purchase price that are not yet finalized are related to direct and indirect taxes, and, as such, the Company's estimates and assumptions are subject to change within the measurement period.

The Company’s preliminary purchase price allocation to net tangible and intangible assets of SCIO is as follows:

Assets:
Cash and cash equivalents	$	9,842
Restricted cash	2,790
Accounts receivable	19,924
Other current assets	2,076
Property and equipment	1,824
Other assets	1,751
Intangible assets
Customer relationships	47,800
Developed technology	21,400
Trade names and trademarks	3,700
	111,107
Liabilities:
Current liabilities	(12,482		)
Deferred tax liabilities, net	(17,132		)
Other non-current liabilities	(200		)
	(29,814		)
Net assets acquired	$	81,293
Goodwill	163,751
Total purchase consideration	$	245,044

The fair values of the trade names and trademarks intangible assets were determined by using an “income approach”, specifically the relief-from-royalty approach. The basic principle of the relief-from-royalty method is that without ownership of the subject intangible asset, the user of that intangible asset would have to make a stream of payments to the owner of the asset in return for the rights to use that asset. By acquiring the intangible asset, the user avoids these payments. Therefore, a portion of SCIO’s earnings, equal to the after-tax royalty that would have been paid for the use of the asset, can be attributed to the firm’s ownership. The trade names and trademarks are being amortized on a straight-line basis (which approximates the economic pattern of benefits) over the estimated economic life of 3 years.

The fair values of the developed technology intangible assets were also determined by the relief-from-royalty approach. Similarly, this approach is based on the assumption that in lieu of ownership, a firm would be willing to pay a royalty in order to exploit the related benefits of the technology. Therefore, a portion of SCIO’s earnings, equal to the after-tax royalty that would have been paid for the use of the technology, can be attributed to the firm’s ownership of the technology. The technology assets are being amortized on a straight-line basis (which approximates the economic pattern of benefits) over the estimated economic life of 5 years.

The fair values of the customer relationships were determined by using an “income approach”, specifically the Multi-Period Excess Earnings Method ("MPEEM"). The MPEEM is a specific application of the discounted cash flow method. The principle behind the MPEEM is that the value of an intangible asset is equal to the present value of the incremental after-tax cash flows attributable only to the subject intangible asset after deducting Contributory Asset Charges ("CAC"). The principle behind a CAC is that an intangible asset ‘rents’ or ‘leases’ from a hypothetical third party all the assets it requires to produce the cash flows resulting from its development, that each project rents only those assets it needs (including elements of goodwill) and not the ones that it does not need, and that each project pays the owner of the assets a fair return on (and of, when appropriate) the value of the rented assets. The customer relationship assets are being amortized on a straight-line basis (which approximates the economic pattern of benefits) over the estimated economic life of 10 years.

The goodwill recognized is attributable primarily to expected synergies from continuing operations of SCIO and the Company. The amount of goodwill recognized from SCIO's acquisition is not deductible for tax purposes. The goodwill has been assigned to our Analytics reportable segment based upon the Company’s assessment of nature of services rendered by SCIO.

Acquisition-related costs

Acquisition-related costs are being expensed as incurred and are included in general and administrative expenses in the unaudited consolidated statements of income. The Company recognized acquisition-related costs, which were incurred to effect business combination, for its SCIO and Health Integrated acquisitions of $nil and $363 during the three months ended March 31, 2019 and 2018, respectively.

Goodwill

The following table sets forth details of changes in goodwill by reportable segment of the Company:

	Insurance			Healthcare			TT&L			F&A			All Other		Analytics		Total
Balance at January 1, 2018	$	38,333		$	35,233		$	13,679		$	48,372		$	5,326	$	63,538	$	204,481

During the fourth quarter of 2018, the Company performed its annual impairment test of goodwill for all its reporting units. Based on the results, the fair values of each of the Company’s reporting units exceeded their carrying values except for the Health Integrated reporting unit, within the Healthcare operating segment. The primary factors contributing to a reduction in the fair value of the Health Integrated reporting unit were: (i) revenues and profitability in 2018 were significantly lower than the Company’s budget; and (ii) significant changes to the Company's estimated future cash flows and long-term growth assumptions for the Health Integrated reporting unit driven by loss of customer contracts, cost pressures and the Company’s most recent views of the long-term outlook for the Health Integrated business. As a result of this analysis, the Company recognized a goodwill impairment charge of $14,229 during the fourth quarter to write down the carrying value of Health Integrated’s goodwill to its fair value of $nil as of December 31, 2018. This impairment loss was recorded in the consolidated statements of income under "impairment charges".

As of March 31, 2019, the Company believes no other goodwill impairment exists, apart from the impairment charges discussed above, and that the remaining goodwill is recoverable for all of its reporting units; however, there can be no assurances that additional 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. It is reasonably possible that the judgments and estimates described above could change in future periods.

Amortization expense	$	5,528	$	3,947

During the fourth quarter of 2018, the Company recognized impairment charges of $5,549 and $278 related to its customer relationships and trademarks intangible assets, respectively, in the Health Integrated reporting unit, within the Healthcare operating segment. The Company tested these intangible assets for recoverability due to indicators warranting the impairment test such as: (i) revenues and profitability in 2018 were significantly lower than the Company’s budget, and (ii) significant changes to the Company's estimated future cash flows and long-term growth assumptions for the Health Integrated reporting unit driven by loss of customer contracts, cost pressures and the Company’s most recent views of the long-term outlook for the Health Integrated business. Based on the results of its testing, the Company determined that the carrying value of the intangible assets was not

recoverable, and an impairment charge was recorded to the extent that carrying value exceeded estimated fair value.

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 and 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 $410,189 (including $6,250 of range forward contracts) as of March 31, 2019 and $362,435 (including $6,900 of range forward contracts) as of December 31, 2018.

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) are recorded along with the underlying hedged item in the same line of unaudited consolidated statements of income as either part of “Cost of revenues”, “General and administrative expenses”, “Selling and marketing expenses”, “Depreciation and amortization”, as applicable.

The Company also enters into foreign currency forward contracts to economically hedge its intercompany balances and other monetary assets and liabilities denominated in currencies other than functional currencies. These derivatives do not qualify as fair value hedges under ASC 815. Changes in the fair value of these derivatives are recognized in the unaudited consolidated statements of income and are included in foreign exchange gain/(loss). The Company’s primary exchange rate exposure is with the Indian Rupee, the U.K. pound sterling and the Philippine peso. The Company also has exposure to Colombian pesos, Czech Koruna, the Euro, South African ZAR and other local currencies in which it operates. Outstanding foreign currency forward contracts amounted to $100,204 and GBP 12,767 as of March 31, 2019 and amounted to $125,503, GBP 15,616 and EUR 512 as of December 31, 2018.

The Company estimates that approximately $2,467 of net derivative gains, excluding tax effects, included in accumulated other comprehensive loss representing changes in the value of cash flow hedges, could be reclassified into earnings within the next twelve months based on exchange rates prevailing as of March 31, 2019. At March 31, 2019, the maximum outstanding term of the cash flow hedges was 45 months.

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

Debt Disclosure [Abstract]

Borrowings

Borrowings

Revolver Credit Agreement

On November 21, 2017, the Company and each of the Company’s wholly owned material domestic subsidiaries entered into a Credit Agreement with certain lenders, and Citibank, N.A. as Administrative Agent (the “Credit Agreement”). The Credit Agreement provides for a $200,000 revolving credit facility (the “Credit Facility”) with an option to increase the commitments by up to $100,000, subject to certain approvals and conditions as set forth in the Credit Agreement. The Credit Agreement also includes a letter of credit sub facility. The Credit Facility has a maturity date of November 21, 2022 and is voluntarily pre-payable from time to time without premium or penalty. Borrowings under the Credit Agreement may be used for working capital and general corporate purposes, including permitted acquisitions. On July 2, 2018, the Company exercised its option under the Credit Agreement to increase the commitments by $100,000 thereby utilizing the entire revolver under the Credit Facility of $300,000, to fund SCIO acquisition. The incremental commitments were made pursuant to (and constitute part of) the existing commitments and shall be subject to the terms and conditions applicable to the existing commitments as set forth in the Credit Agreement.

Depending on the type of borrowing, loans under the Credit Agreement bear interest at a rate equal to the specified prime rate (alternate base rate) or adjusted LIBO rate, plus, in each case, an applicable margin. The applicable margin is tied to the Company’s total net leverage ratio and ranges from 0% to 0.75% per annum with respect to loans pegged to the specified prime rate, and 1.00% to 1.75% per annum on loans pegged to the adjusted LIBO rate. The revolving credit commitments under the Credit Agreement are subject to a commitment fee, which is also tied to the Company’s total net leverage ratio, and ranges from 0.15% to 0.30% per annum on the average daily amount by which the aggregate revolving commitments exceed the sum of

outstanding revolving loans and letter of credit obligations. The Credit Facility carried an effective interest rate of 3.9% and 3.3% per annum during the three months ended March 31, 2019 and 2018.

Obligations under the Credit Agreement are guaranteed by the Company’s material domestic subsidiaries and are secured by all or substantially all of the assets of the Company and our material domestic subsidiaries. The Credit Agreement contains customary affirmative and negative covenants, including, but not limited to, restrictions on the ability to incur indebtedness, create liens, make certain investments, make certain dividends and related distributions, enter into, or undertake, certain liquidations, mergers, consolidations or acquisitions and dispose of assets or subsidiaries. In addition, the Credit Agreement contains a covenant to not permit the interest coverage ratio (the ratio of EBITDA to cash interest expense) or the total net leverage ratio (total funded indebtedness, less unrestricted domestic cash and cash equivalents not to exceed $50,000 to EBITDA) for the four consecutive quarter period ending on the last day of each fiscal quarter, to be less than 3.5 to 1.0 or more than 3.0 to 1.0, respectively. As of March 31, 2019, the Company was in compliance with all financial and non-financial covenants listed under the Credit Agreement.

The Company entered into a second amendment (the “Amendment”) to its Credit Agreement, as amended, among the Company, as borrower, with certain lenders, and Citibank, N.A. as Administrative Agent to, among other things, permit the issuance by the Company of the convertible notes, and settlement upon maturity or conversion thereof, in accordance with the Investment Agreement, the indenture dated as of October 4, 2018 and the other documents entered into in connection therewith.

As of March 31, 2019, the Company had outstanding indebtedness under the credit facility of $186,000, of which $20,000 is expected to be repaid within the next twelve months and is included under “current portion of long-term borrowings” and of which $166,000 is included under “long-term borrowings” in the unaudited consolidated balance sheets. As of December 31, 2018, the Company had an outstanding indebtedness under the credit facility of $150,000, of which $20,000 was included under “current portion of long-term borrowings,” and the balance of $130,000 was included under “long-term borrowings” in the consolidated balance sheets.

The Company incurred certain debt issuance costs, which are deferred and amortized as an adjustment to interest expense over the term of the credit facility. The unamortized debt issuance costs as of March 31, 2019 and December 31, 2018 was $942 and $1,006, respectively, and is included under "other current assets" and “other assets” in the unaudited consolidated balance sheets.

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 3.50% Convertible Senior Notes due October 1, 2024 (the “Notes”). The transactions contemplated by the Investment Agreement, including the issuance of the Notes, closed on October 4, 2018. The Notes bear interest at a rate of 3.50% per annum, payable semi-annually in arrears in cash on April 1 and October 1 of each year. During the three months ended March 31, 2019, the Company recognized interest expense of $1,313. The Notes are convertible at an initial conversion rate of 13.3333 shares of the common stock per $1,000 principal amount of the Notes (which represents an initial conversion price of approximately $75 per share). With certain exceptions, upon a fundamental change, as defined in the Indenture, the holders of the Notes may require that the Company to repurchase all or part of the principal amount of the Notes at a purchase price equal to the principal amount plus accrued and unpaid interest. The Company may 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 exceeds 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 may 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 Company used the proceeds from the issuance of Notes to repay $150,000 of its outstanding borrowings under the Credit Facility.

The net proceeds from the issuance of Notes were approximately $149,000, after deducting debt issuance costs of $1,000 and offering expenses of approximately $442 paid by the Company. These transaction and debt issuance costs were allocated between the liability and equity components based on their relative values. The transaction costs and debt issuance costs allocated to the liability and equity components were $1,279 and $163 respectively. The debt issuance costs allocated to the liability component are deferred and amortized as an adjustment to interest expense over the term of the Notes. The unamortized debt issuance costs

is presented as a direct reduction from the Notes in the unaudited consolidated balance sheets. The unamortized debt issuance costs as of March 31, 2019 and December 31, 2018 was $1,178 and $1,127, respectively.

The Company accounted for the liability and equity components of the Notes separately to reflect its non-convertible debt borrowing rate. The estimated fair value of the liability component at issuance of $133,077 was determined using a discounted cash flow technique, which considered debt issuances with similar features of the Company’s debt, excluding the conversion feature. The resulting effective interest rate for the Notes was 5.75% per annum. The excess of the gross proceeds received over the estimated fair value of the liability component totaling $16,923 was allocated to the conversion feature (equity component, recorded as additional paid-in capital) with a corresponding offset recognized as a discount to reduce the net carrying value of the Notes. The discount is being amortized to interest expense over a six-year period ending October 1, 2024 (the expected life of the liability component) using the effective interest method. During the three months ended March 31, 2019, the Company amortized $600 of the discount to interest expense. At the time of issuance, the Company evaluated the Notes in accordance with ASC 815-15 and determined that the Notes contain a single embedded derivative, being the call option having market interest rates as underlying, which does not require bifurcation as the features clearly and closely related to the host instrument. The Company determined that the value of this embedded derivative was nominal as of the date of issuance.

Borrowings also includes structured payables which are in the nature of debt, amounting to $1,542 and $2,114 as of March 31, 2019 and December 31, 2018, respectively, of which $876 and $1,423 is included under "current portion of long-term borrowings", $666 and $691, respectively, under "long-term borrowings" in the unaudited consolidated balance sheets.

Future principal payments/maturities for all of the Company's borrowings as of March 31, 2019 were as follows:

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 adjusted for discrete items, if any, that are taken into account in the relevant period. 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 Company recorded income tax expense (benefit) of $4,200 and $(4,453) for the three months ended March 31, 2019 and 2018, respectively. The effective tax rate increased from (23.7)% during the three months ended March 31, 2018 to 22.1% during the three months ended March 31, 2019 primarily as a result of (i) an adjustment of $4,836 reducing the provisional transition tax on the mandatory deemed repatriation of accumulated earnings and profits ("E&P") of foreign subsidiaries recognized during the three months ended March 31, 2018, and (ii) the recording of excess tax benefits related to stock awards of $4,827 pursuant to ASU No. 2016-09 during the three months ended March 31, 2018 compared to $1,015 during the three months ended March 31, 2019.

Commitments and Contingencies

Fixed Asset Commitments

At March 31, 2019, the Company has committed to spend approximately $9,552 under agreements to purchase property and equipment. This amount is net of capital advances paid in respect of these purchases.

Other Commitments

Certain units of the Company’s Indian subsidiaries were established as 100% Export-Oriented units or under the Software Technology Parks of India (“STPI”) scheme promulgated by the Government of India. These units are exempt from customs, central excise duties, and levies on imported and indigenous capital goods, stores, and spares. The Company has undertaken to pay custom duties, service taxes, levies, and liquidated damages payable, if any, in respect of imported and indigenous capital goods, stores and spares consumed duty free, in the event that certain terms and conditions are not fulfilled. The Company’s management believes, however, that these units have in the past satisfied and will continue to satisfy the required conditions.

The Company’s operations centers in the Philippines are registered with the Philippine Economic Zone Authority (“PEZA”). The registration provides the Company with certain fiscal incentives on the import of capital goods and requires ExlService Philippines, Inc. to meet certain performance and investment criteria. The Company’s management believes that these centers have in the past satisfied and will continue to satisfy the required criteria.

In March 2017, the Company was named as a defendant in a putative class action lawsuit filed in California, which challenged the classification of independent contractors. The parties participated in a mediation in early 2018. As the result of the mediation, a settlement was reached pursuant to which the Company agreed, without admission of wrongdoing, to pay a total of $2,400, of which $1,200 was paid in 2018 and the remainder has been paid during the three months ended March 31, 2019.

Contingencies

U.S. and Indian transfer pricing regulations require that any international transaction involving associated enterprises be at an arm’s-length price. Accordingly, the Company determines the appropriate pricing for the international transactions among its associated enterprises on the basis of a detailed functional and economic analysis involving benchmarking against transactions

among entities that are not under common control. The tax authorities have jurisdiction to review this arrangement and in the event that they determine that the transfer price applied was not appropriate, the Company may incur increased tax liability, including accrued interest and penalties. The Company is currently involved in disputes with the Indian tax authorities over the application of some of its transfer pricing policies for some of its subsidiaries. Further, the Company and a U.S. subsidiary are engaged in tax litigation with the income-tax authorities in India on the issue of permanent establishment. The Company is subject to taxation in the United States and various states and foreign jurisdictions. For the U.S. and India, tax year 2015 and subsequent tax years remain open for examination by the tax authorities as of March 31, 2019.

The aggregate amount demanded by Income tax authorities (net of advance payments, if any) from the Company related to its transfer pricing issues for tax years 2003 to 2014 and its permanent establishment issues for tax years 2003 to 2007 as of March 31, 2019 and December 31, 2018 is $17,863 and $18,177, respectively, of which the Company has made payments or provided bank guarantee to the extent $8,244 and $8,171, respectively. Amounts paid as deposits in respect of such assessments aggregating to $6,328 and $6,273 as of March 31, 2019 and December 31, 2018, respectively, are included in “Other assets” and amounts deposited for bank guarantees aggregating to $1,916 and $1,899 as of March 31, 2019 and December 31, 2018, respectively, are included in “Restricted cash” in the non-current assets section of the Company’s unaudited consolidated balance sheets.

Based on the facts underlying the Company’s position and its experience with these types of assessments, the Company believes that its position will more likely than not be sustained upon final examination by the tax authorities based on its technical merits as of the reporting date and accordingly has not accrued any amount with respect to these matters in its 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.

Summary of Significant Accounting Policies (Policies)

3 Months Ended

Mar. 31, 2019

Accounting Policies [Abstract]

Basis of Preparation

The unaudited consolidated financial statements have been prepared in conformity with United States generally accepted accounting principles (“US 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 US 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, 2018.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.

Principles of Consolidation

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 income and expenses arising from intra-group transactions, are eliminated while preparing those 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 US GAAP.

The Company’s investments in equity affiliates are initially recorded at cost and any excess cost 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 is recognized in the unaudited consolidated statements of income.

Non-controlling interest is the equity in a subsidiary not attributable, directly or indirectly, to the parent and it represents the minority partner’s interest in the operations of ExlService Colombia S.A.S. Non-controlling interest consists of the amount of such interest at the date of obtaining control over the subsidiary, and the non-controlling interest's share of changes in equity since that date. The non-controlling interest in the operations for all periods presented were insignificant and is included under general and administrative expenses in the unaudited consolidated statements of income.

Use of Estimates

The preparation of the unaudited consolidated financial statements in conformity with US GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the 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 financial statements include, but are not limited to, allowance for doubtful receivables, expected recoverability from customers with contingent fee arrangements, 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 incremental borrowing rate to calculate lease liabilities and right-of-use (“ROU”) assets, lease term to calculate lease cost, depreciation and amortization periods, purchase price allocation, recoverability of long-lived assets including goodwill and intangibles, and estimated costs to complete fixed price contracts.

Employee Benefits

Contributions to defined contribution plans are charged to the unaudited consolidated statements of income in the period in which services are rendered by the covered employees. Current service costs for defined benefit plans are accrued in the period to which they relate. The liability in respect of defined benefit plans is calculated annually by the Company using the projected unit credit method. Prior service cost, if any, resulting from an amendment to a plan is recognized and amortized over the remaining period of service of the covered employees.

The Company recognizes its liabilities for compensated absences depending on whether the obligation is attributable to employee services already rendered, relates to rights that vest or accumulate and payment is probable and estimable.

The Company includes the service cost component of the net periodic benefit cost in the same line item or items as other compensation costs arising from services rendered by the respective employees during the period. The interest cost, expected return on plan assets and amortization of actuarial gains/loss are classified in “Other income, net”. Refer Note 20 to the unaudited consolidated financial statements for details.

Cash and Cash Equivalents and Restricted Cash

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

Restricted cash represents amounts on deposit with banks against bank guarantees issued through banks in favor of relevant statutory authorities for equipment imports, deposits for obtaining indirect tax registrations and for demands against pending income tax assessments (refer Note 26 to the unaudited consolidated financial statements for details). These deposits with banks have maturity dates after March 31, 2020. Restricted cash presented under current assets represents funds held on behalf of clients in dedicated bank accounts.

For purposes of the unaudited statements of cash flows, the Company includes in its cash and cash-equivalent balances those amounts that have been classified as restricted cash and restricted cash equivalents.

Revenue Recognition

Revenue is recognized when services are provided to our customers, in an amount that reflects the consideration we expect to be entitled to in exchange for our services.

Revenue is measured based on consideration specified in a contract with a customer and excludes discounts and amounts collected on behalf of third parties. The Company recognizes revenue when it satisfies a performance obligation by providing services to a customer.

Taxes assessed by a governmental authority that are both imposed on and concurrent with a specific revenue-producing transaction, that are collected by the Company from a customer, are excluded from revenue.  

Adoption of ASU 2014-09 Topic 606, “Revenue from Contracts with Customers” (Topic 606)

On January 1, 2018, the Company adopted Topic 606 using the modified retrospective method and applied its guidance to those contracts which were not completed as of January 1, 2018. Results for reporting periods beginning after January 1, 2018 are presented under Topic 606. The effect from the adoption of Topic 606 was not material to the Company's financial statements.

Nature of services

The Company derives its revenues from operations management and analytics services. The Company operates in the business process management (“BPM”) industry providing operations management and analytics services helping businesses enhance revenue growth and improve profitability. The Company provides BPM or “operations management” services, which typically involve transfer to the Company of business operations of a client, after which it administers and manages those operations for its client on an ongoing basis. The Company also provides industry-specific digital transformational services related to operations management services, and analytics services that focus on driving improved business outcomes for clients by generating data-driven insights across all parts of their business. The Company also provides care optimization and reimbursement optimization

services, for its clients through its healthcare analytics solutions and services. The Company offers integrated solutions to help its clients with cost containment by leveraging technology platforms, customizable and configurable analytics and expertise in healthcare reimbursements to help clients enhance their claims payment accuracy.

Type of Contracts

i. a) Revenues under time-and-material, transaction and outcome-based contracts are recognized as the services are performed. When the terms of the client contract specify service level parameters that must be met (such as turnaround time or accuracy), the Company monitors such service level parameters to determine if any service credits or penalties have been incurred. Revenues are recognized net of any penalties or service credits that are due to a client.

b) In respect of arrangements involving subcontracting, in part or whole of the assigned work, the Company evaluates whether it is in control of the services before the same are transferred to the customer to assess whether it is Principal or Agent in the arrangement based on guidance on “Principal versus agent considerations” in Topic 606.

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

iii. Revenues from the Company's software and related services contracts, which are not significant, are primarily related to maintenance renewals or incremental license fees for additional users. Maintenance revenues are generally recognized on a straight-line basis over the annual contract term. Fees for incremental license without any associated services are recognized upon delivery of the related incremental license. To a lesser extent, software and related services contracts may contain software license, related services and maintenance elements as a multiple element arrangement. In such cases, revenue is allocated to maintenance based on the price charged when that element is sold separately.

iv. Revenues from reimbursement optimization services having contingent fee arrangements are recognized by the Company at the point in time when a performance obligation is satisfied, which is when it identifies an overpayment claim and the same is acknowledged by its customers. In such contracts, the Company’s consideration is contingent upon the actual collections made by its customers and subsequent potential retraction claims. Based on guidance on “variable consideration” in Topic 606, the Company uses its historical experience and projections to determine the expected recoveries from its customers and recognizes revenue based upon such expected recoveries. Any adjustment required due to change in estimates are recorded in the period in which such change is identified.

Arrangements with Multiple Performance Obligations

The Company’s contracts with customers do not generally bundle different services together except for software and related services contracts, which are not significant, involving implementation services and post contract maintenance services. In such software and related services contracts, revenue is allocated to each performance obligation based on the relative standalone selling price.

A separate contract is generally drafted for each type of service sold, even if to the same customer. The typical length of a contract is 3 to 5 years for our operations management contracts.

Allocation of transaction price to performance obligations

The transaction price is allocated to performance obligations on a relative standalone selling price basis. Standalone selling prices are estimated by reference to the total transaction price less the sum of the observable standalone selling prices of other goods or services promised in the contract.  In assessing whether to allocate variable consideration to a specific part of the contract,

the Company considers the nature of the variable payment and whether it relates specifically to its efforts to satisfy a specific part of the contract.

Variable Consideration

Variability in the transaction price arises primarily due to service level agreements, cost of living adjustments, and pre-payment and volume discounts.

The Company considers its experience with similar transactions and expectations regarding the contract in estimating the amount of variable consideration that should be recognized during a period.

The Company believes that the expected value method is most appropriate for determining the variable consideration since the company has large number of contracts with similar nature of transactions/services.

Unbilled Receivables

Unbilled receivables represents revenues recognized for services rendered between the last billing date and the balance sheet date. Unbilled receivables also include revenues recognized from reimbursement optimization services when the Company identifies an overpayment claim and the same is acknowledged by its customers, however not invoiced at the balance sheet date. Accordingly, amounts for services that the Company has performed and for which an invoice has not yet been issued to the customers are presented as a part of contract assets as accounts receivable.

Deferred Revenue

The Company has deferred revenue attributable to certain process transition activities, with respect to its customers where such activities do not represent separate performance obligations. Revenues related to such transition activities are contract liabilities classified under “Deferred Revenue” in the Company's unaudited consolidated balance sheets and subsequently recognized ratably over the period in which the related services are performed. Deferred revenue also includes the amount for which services have been rendered but other conditions of revenue recognition are not met, for example where the Company does not have persuasive evidence of an arrangement with customer. Costs related to such transition activities are contract fulfillment costs, and thereby classified under “Other Current Assets” and “Other Assets” in the unaudited consolidated balance sheets, and are recognized ratably over the estimated expected period of benefit, under Cost of Revenues in the unaudited consolidated statements of income.

Other incremental and direct costs incurred for acquiring contracts, such as sales commissions are contract acquisition costs and thereby classified under “Other Current Assets” and “Other Assets” in the unaudited consolidated balance sheets. Such costs are amortized over the expected period of benefit and recorded under Selling and marketing expenses in the unaudited consolidated statements of income.

Any upfront payments made to customers are contract assets and classified under “Other Current Assets and Other Assets” in the unaudited consolidated balance sheets. Such costs are amortized over the expected period of benefit and are recorded as an adjustment to transaction price and reduced from revenues.

Reimbursements of out-of-pocket expenses received from clients are included as part of revenues.

Payment terms

All Contracts entered into by the Company specify the payment terms and are defined for each contract separately. Usual payment terms range between 30-60 days. The Company does not have any extended payment terms clauses in existing contracts. At times, the Company enters into fixed price contracts and software licenses involving significant implementation wherein the milestones are defined such that the Company can recover the costs with a reasonable margin.

Practical expedients and exemptions

The Company does not disclose the value of unsatisfied performance obligations for (i) contracts with an original expected length of 1 year or less and (ii) contracts for which the Company recognizes revenue at the amount to which we have the right to invoice for services performed.

Accounts Receivable

We record accounts receivable net of allowances for doubtful accounts. Allowances for doubtful accounts are established through the evaluation of aging of accounts receivables, prior collection experience, current market conditions, clients’ financial condition and the amount of accounts receivables in dispute to estimate the collectability of these accounts receivables.

Leases

The Company determines if an arrangement is a lease at inception. Operating leases are included in operating lease right-of-use ("ROU") assets, current portion of operating lease liabilities and operating lease liabilities, less current portion in the Company's unaudited consolidated balance sheets. Finance leases are included in property and equipment, current portion of finance lease obligations and finance lease obligations, less current portion in the Company's unaudited consolidated balance sheets.

ROU assets represent the Company’s right to use an underlying asset for the lease term and lease liabilities represent the Company’s obligation to make lease payments arising from the lease. Operating lease ROU assets and liabilities are recognized at commencement date based on the present value of lease payments over the lease term. For leases in which the rate implicit in the lease is not readily determinable, the Company uses its incremental borrowing rate based on the information available at commencement date in determining the present value of lease payments. Lease terms include options to extend or terminate the lease when it is reasonably certain that the Company will exercise that option. Lease expense for operating lease arrangements is recognized on a straight-line basis over the lease term. The Company has lease agreements with lease and non-lease components, which are accounted for separately.

On January 1, 2019, the date of initial application, the Company adopted, Leases (Topic 842), using the modified retrospective method. The modified retrospective method provides a method of recording those leases which had not expired as of the date of adoption of January 1, 2019. The prior period unaudited consolidated financial statements have not been retrospectively adjusted and continues to be reported under Topic 840.

The Company elected the practical expedient permitted under the transition guidance under Topic 842, which amongst other matters, allowed the Company (i) not to apply the recognition requirements to short-term leases (leases with a lease term of 12 months or less), (ii) not to reassess whether any expired or existing contracts are or contain leases, (iii) not to reassess the lease classification for any expired or existing leases, and (iv) not to reassess initial direct costs for any existing leases.

The adoption resulted in the recognition of ROU assets of $80,328, net of deferred rent of $8,626 and lease liabilities of $88,954 for operating leases as of January 1, 2019. The Company's accounting for finance leases remained substantially unchanged. The adoption had no impact on opening balance of retained earnings.

Recent Accounting Pronouncements and Recently Adopted Accounting Pronouncements

In June 2016, the Financial Accounting Standards Board ("FASB") issued ASU No. 2016-13, Financial Instruments - Credit Losses, which requires a financial asset (or a group of financial assets) measured at amortized cost basis to be presented at the net amount expected to be collected. The allowance for credit losses is a valuation account that is to be deducted from the amortized cost of the financial asset(s) so as to present the net carrying value at the amount expected to be collected on the financial asset. The new guidance is effective for fiscal years beginning after December 15, 2019, including interim periods within those fiscal years. The amendment should be applied through a modified retrospective approach. Early adoption as of the fiscal years beginning

after December 15, 2018 is permitted. The Company is currently evaluating the impact that the adoption of this guidance will have on its consolidated financial statements.

In June 2018, FASB issued ASU No. 2018-07, Compensation-Stock Compensation (Topic 718): Improvements to Non-employee Share-Based Payment Accounting. This ASU involves several aspects of the accounting for non-employee share-based payment transactions resulting from expanding the scope of Topic 718, Compensation-Stock Compensation, to include share-based payment transactions for acquiring goods and services from non-employees. The amendments in this ASU affect all entities that enter into share-based payment transactions for acquiring goods and services from non-employees. This ASU is effective for public business entities for fiscal years beginning after December 15, 2018, including interim periods within that fiscal year.  Early adoption is permitted, but no earlier than an entity’s adoption date of Topic 606. The adoption of this ASU is not expected to have any material effect on the Company’s consolidated financial statements.

In August 2018, FASB issued ASU No. 2018-13, Fair Value Measurement (Topic 820): Changes to the Disclosure Requirements for Fair Value Measurement. The amendments in this ASU modify the disclosure requirements on fair value measurements in Topic 820, based on the concepts in the Concepts Statement, including the consideration of costs and benefits. The amendments in ASU are effective for fiscal years beginning after December 15, 2019, including interim periods within those fiscal years. An entity is permitted to early adopt either the entire standard or only the provisions that eliminate or modify requirements. The adoption of this ASU is not expected to have any material effect on the Company’s consolidated financial statements.

In August 2018, FASB issued ASU No. 2018-14, Compensation-Retirement Benefits-Defined Benefit Plans-General (Subtopic 715-20): Changes to the Disclosure Requirements for Defined Benefit Plans. The amendments in this Update remove disclosures that no longer are considered cost beneficial, clarify the specific requirements of disclosures, and add disclosure requirements identified as relevant. The amendments in ASU are effective for fiscal years beginning after December 15, 2020. An entity is permitted to early adopt this Update. The adoption of this ASU is not expected to have any material effect on the Company’s consolidated financial statements.

In August 2018, FASB issued ASU No. 2018-15, Intangibles - Goodwill and Other - Internal-Use Software (Subtopic 350-40): This ASU aligns the requirements for capitalizing implementation costs incurred in a hosting arrangement that is a service contract with the requirements for capitalizing implementation costs incurred to develop or obtain internal-use software (and hosting arrangements that include an internal-use software license). Accordingly, the ASU requires an entity (customer) in a hosting arrangement that is a service contract to follow the guidance in FASB Accounting Standard Codification Subtopic 350-40 on internal-use software to determine which implementation costs to capitalize as an asset related to the service contract and which costs to expense. The ASU 2018-15 also provides guidance on amortization and impairment of any costs capitalized, along with new presentation and disclosure requirements. The new guidance is effective for fiscal years beginning after December 15, 2019.  Early adoption is permitted and both prospective and retrospective transition methods are allowed. The Company is currently evaluating the impact that the adoption of this guidance will have on its consolidated financial statements.

(h) Recently Adopted Accounting Pronouncements

In February 2016, FASB issued ASU No. 2016-02, Leases (Topic 842), which requires the identification of arrangements that should be accounted for as leases. Lease arrangements exceeding a twelve months term should be recognized as assets with corresponding liabilities on the balance sheet of the lessee. This ASU requires recognition of an ROU asset and lease obligation for those leases classified as operating leases under Topic 840, while the income statement will reflect lease expense for operating leases. The balance sheet amounts recorded for existing operating leases at the date of adoption of this ASU must be calculated using the applicable incremental borrowing rate. The Company adopted Topic 842 as of January 1, 2019 using the modified retrospective method provided by ASU 2018-11. The adoption had a material impact on the Company's unaudited consolidated balance sheets, but did not have a material impact on the Company's unaudited consolidated income statements and unaudited consolidated statements of cash flows. The most significant impact was the recognition of ROU assets and lease liabilities for operating leases, while the Company's accounting for finance leases remained substantially unchanged. Refer Note 21 to the unaudited consolidated financial statements for details.

In July 2018, FASB issued ASU No. 2018-11, Leases (Topic 842), which provide entities with an additional (and optional) transition method to adopt the new leases standard. Under this new transition method, an entity initially applies the new leases standard at the adoption date and recognizes a cumulative-effect adjustment to the opening balance of retained earnings in the period of adoption. Consequently, an entity’s reporting for the comparative periods presented in the financial statements in which

it adopts the new leases standard will continue to be in accordance with current GAAP (Topic 840, Leases). The Company adopted Topic 842 as of January 1, 2019 using this ASU. Refer Note 21 to the unaudited consolidated financial statements for details.
