Accounting Policies [Abstract]
Summary of Significant Accounting Policies	2. Summary of Significant Accounting Policies Principles of Consolidation The accompanying unaudited consolidated financial statements include the financial statements of ExlService Holdings and all of its subsidiaries. All intercompany balances and transactions have been eliminated in consolidation. 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, service tax receivables, assets and obligations related to employee benefit plans, deferred tax valuation allowances, income-tax uncertainties and other contingencies, valuation of derivative financial instruments, stock-based compensation expense, depreciation and amortization periods, purchase price allocation, recoverability of long-term assets including goodwill and intangibles, and estimates to complete the fixed price contracts. In accordance with its policy, the Company reviews the estimated useful lives of its fixed assets on an ongoing basis. This review indicated that the actual lives of certain fixed assets were longer than the estimated useful lives used for depreciation purposes in the Company’s financial statements. As a result, effective January 1, 2015, the Company changed its estimates of the useful lives of its certain fixed assets to better reflect the estimated periods during which these assets will remain in service. The effect of change in estimated useful life of assets reduced depreciation expense by $468 and $935, increased net income by $281 and $561 and increased basic and diluted earnings per share by $0.01 and $0.02, respectively during the three months and six months ended June 30, 2015. Revenue Recognition As part of reimbursing the Travelers Indemnity Company (“Travelers”) for certain of their transition related expenses (the “disentanglement costs”), the Company recognized $5,718 and $8,189 of such reimbursements as a reduction of our revenues during the three months and six months ended June 30, 2014 respectively, in accordance with Accounting Standards Codification topic 605-50-45, “Revenue Recognition.” The Company did not incur any reimbursements of disentanglement costs during the three months and six months ended June 30, 2015 and also does not anticipate incurring any additional reimbursements of disentanglement costs related to Travelers going forward. Revenue from analytical services including modeling, targeting and designing of campaigns and mail marketing including email marketing and other digital solutions is typically recognized on delivery of such campaigns. In respect of arrangements involving sub-contracting of part or whole of the assigned work, the Company evaluates revenue to be recognized under ASC 605-45 “Revenue recognition – Principal agent considerations”. Investments The Company’s investments consist primarily of time deposits and mutual funds and are in accordance with the Company’s risk management policies. Time deposits with financial institutions are valued at cost and approximate fair value. Interest earned on such investments is included in interest and other income. Investments with original maturities greater than ninety days but less than twelve months are classified as short-term investments. Investments with maturities greater than twelve months from the balance sheet date are classified as long-term investments. The mutual fund investments are in debt and money market funds which invest in instruments of various maturities in India. The Company accounts for these investments in accordance with the fair value option under ASC topic 825-10 (“ASC No. 825-10”) and change in fair value is included in interest and other income. The fair value represents original cost (on the acquisition date) and the net asset value (“NAV”) as quoted, at each reporting period. Gain or loss on the disposal of these investments is calculated using the weighted average cost of the investments sold or disposed and is included in interest and other income. Accrued expenses and other current liabilities Accrued expenses and other current liabilities consist of the following: June 30, December 31, 2015 2014 Accrued expenses $ 27,095 $ 24,451 Derivative instruments 1,281 2,385 Client liability account 2,983 9,241 Other current liabilities 6,212 4,129 Accrued expenses and other current liabilities $ 37,571 $ 40,206 Non-current liabilities Non-current liabilities consist of the following: June 30, December 31, 2015 2014 Derivative instruments $ 784 $ 576 Unrecognized tax benefits 4,241 2,878 Deferred rent 6,268 5,977 Retirement benefits 1,531 1,544 Other non-current liabilities 1,217 1,895 Non-current liabilities $ 14,041 $ 12,870 Interest and other income Other income (expense), net consists of the following: Three months ended June 30, Six months ended June 30, 2015 2014 2015 2014 Interest and dividend income* $ 1,510 $ 912 $ 2,912 $ 1,789 Interest expense (360 ) (75 ) (643 ) (188 ) Others, net 185 21 244 216 Other income, net $ 1,335 $ 858 $ 2,513 $ 1,817 * Includes unrealized gain of $718 and $760 and realized gain of $15 and $0, respectively for the three months and six months ending June 30, 2015 on investments carried under fair value option. There were no such unrealized / realized gain/(loss) for the three months and six months ended June 30, 2014. Recent Accounting Pronouncements In May 2014, the Financial Accounting Standards Board (“FASB”) issued ASU No. 2014-09, “Revenue from Contracts with Customers” (“ASU 2014-09”). Earlier the new standard was effective for reporting periods beginning after December 15, 2016. However, in April 2015, FASB deferred the effective date of the new standard. With this deferral, the new standard is effective for reporting periods beginning after December 15, 2017 and early adoption is not permitted. The comprehensive new standard will supersede existing revenue recognition guidance and require revenue to be recognized when promised goods or services are transferred to customers in amounts that reflect the consideration to which the Company expects to be entitled in exchange for those goods or services. Adoption of the new rules could affect the timing of revenue recognition for certain transactions of the Company. ASU 2014-09 is effective for the Company in the first quarter of fiscal 2018 using either one of two methods: (i) retrospectively to each prior reporting period presented with the option to elect certain practical expedients as defined within ASU 2014-09; or (ii) retrospectively with the cumulative effect of initially applying ASU 2014-09 recognized at the date of initial application and providing certain additional disclosures as defined per ASU 2014-09. The Company is currently evaluating the impact of adoption and the implementation approach to be used. In April 2015, FASB issued ASU No. 2015-05, “Intangibles – Goodwill and Other – Internal-Use Software (Subtopic 350-40): Customer’s Accounting for Fees Paid in a Cloud Computing Arrangement” (“ASU 2015-05”). The amendments add guidance to Subtopic 350-40, Intangibles – Goodwill and Other – Internal-Use Software, which will help entities evaluate the accounting for fees paid by a customer in a cloud computing arrangement. The amendments will be effective for fiscal years beginning after December 15, 2015. The Company is currently evaluating the method of adoption and impact this standard will have on its consolidated financial statements and related disclosures. In April 2015, FASB issued ASU No. 2015-03, “Interest—Imputation of Interest” (“ASU 2015-03”), which requires that debt issuance costs related to a recognized debt liability be presented in the balance sheet as a direct deduction from the carrying amount of that debt liability, consistent with debt discounts. The recognition and measurement guidance of debt issuance costs are not affected by the amendments in that update. The standard will be effective for the Company beginning in the first quarter of fiscal year 2016 and requires the Company to apply the new guidance on a retrospective basis on adoption. The adoption of this guidance is not expected to have any impact on the Company’s consolidated financial statements. In May 2015, FASB issued ASU No. 2015-08, “Business Combinations (Topic 805): Pushdown Accounting - Amendments to SEC Paragraphs Pursuant to Staff Accounting Bulletin No. 115” (“ASU 2015-08”). The amendments in ASU 2015-08 amend various SEC paragraphs included in FASB’s Accounting Standards Codification to reflect the issuance of Staff Accounting Bulletin No. 115 (“SAB 115”). SAB 115 rescinds portions of the interpretive guidance included in the SEC’s Staff Accounting Bulletins series and brings existing guidance into conformity with ASU No. 2014-17, “Business Combinations (Topic 805): Pushdown Accounting,” which provides an acquired entity with an option to apply pushdown accounting in its separate financial statements upon occurrence of an event in which an acquirer obtains control of the acquired entity. The adoption of this guidance does not have a material impact on the Company’s consolidated financial statements.

Earnings Per Share	Jun. 30, 2015
Earnings Per Share [Abstract]
Earnings Per Share	3. Earnings Per Share Basic earnings per share is computed by dividing net income to common stockholders by the weighted average number of common shares outstanding during each period. Diluted earnings per share is computed using the weighted average number of common shares plus the potentially dilutive effect of common stock equivalents issued and outstanding at the reporting date, using the treasury stock method. Stock options, restricted stock and restricted stock units that are anti-dilutive are excluded from the computation of weighted average shares outstanding. The following table sets forth the computation of basic and diluted earnings per share: Three months ended June 30, Six months ended June 30, 2015 2014 2015 2014 Numerators: Net income $ 12,074 $ 7,762 $ 21,641 $ 18,910 Denominators: Basic weighted average common shares outstanding 33,417,079 32,812,155 33,327,169 32,668,620 Dilutive effect of share based awards 790,894 861,514 803,303 883,284 Diluted weighted average common shares outstanding 34,207,973 33,673,669 34,130,472 33,551,904 Earnings per share: Basic $ 0.36 $ 0.24 $ 0.65 $ 0.58 Diluted $ 0.35 $ 0.23 $ 0.63 $ 0.56 Weighted average common shares considered anti-dilutive in computing diluted earnings per share 62,084 179,450 116,922 192,669

Segment Reporting [Abstract]
Segment Information	4. Segment Information The Company’s business is divided into two reporting segments: Operations Management (previously called Outsourcing Services) and Analytics and Business Transformation (previously called Transformation Services). The Company changed its reporting segment nomenclature in 2014 in order to more accurately reflect the changing nature of its engagements with the clients. For comparability with the prior periods, the business composition of each segment remains unchanged. The Company provides various types of business process solutions utilizing operations management, analytics and technology. These services are provided in an integrated manner to clients in various industries. The chief operating decision maker (“CODM”) generally reviews financial information at the consolidated statement of income level disaggregated by our two segments, but does not review any information except for revenues and cost of revenues of these individual segments. Therefore, the Company does not allocate or evaluate operating expenses, interest expense or income, capital expenditures, and income taxes to its reporting segments. Consequently, it is not practical to show assets, capital expenditures, depreciation or amortization by segment. The recent acquisition of RPM Direct, LLC and RPM Data Solutions, LLC (collectively, “RPM”) by the Company’s subsidiary ExlService.com, LLC (“ExlService.com”) is classified within the Analytics and Business Transformation segment. Revenues and cost of revenues for each of the three months ended June 30, 2015 and 2014 for the Company’s Operations Management and Analytics and Business Transformation segments, respectively, are as follows: Three months ended June 30, 2015 Three months ended June 30, 2014 Operations Analytics and Total Operations Analytics and Total Revenues, net $ 112,606 $ 43,015 $ 155,621 $ 94,314 $ 25,424 $ 119,738 Cost of revenues (exclusive of depreciation and amortization) 71,535 28,943 100,478 62,494 18,765 81,259 Gross profit $ 41,071 $ 14,072 $ 55,143 $ 31,820 $ 6,659 $ 38,479 Operating expenses 39,895 32,382 Other income 2,357 721 Income tax expense / (benefit) 5,531 (944 ) Net income $ 12,074 $ 7,762 Revenues and cost of revenues for each of the six months ended June 30, 2015 and 2014 for the Company’s Operations Management and Analytics and Business Transformation segments, respectively, are as follows: Six months ended June 30, 2015 Six months ended June 30, 2014 Operations Analytics and Total Operations Analytics and Total Revenues, net $ 223,267 $ 75,864 $ 299,131 $ 194,405 $ 47,130 $ 241,535 Cost of revenues (exclusive of depreciation and amortization) 142,001 51,602 193,603 121,393 34,788 156,181 Gross profit $ 81,266 $ 24,262 $ 105,528 $ 73,012 $ 12,342 $ 85,354 Operating expenses 76,812 63,770 Other income 4,669 847 Income tax expense 11,744 3,521 Net income $ 21,641 $ 18,910

Business Combinations [Abstract]
Business Combinations, Goodwill and Intangible Assets	5. Business Combinations, Goodwill and Intangible Assets RPM Direct LLC and RPM Data Solutions, LLC On March 20, 2015 ExlService.com completed its acquisition of RPM Direct LLC and RPM Data Solutions, LLC (each a “Target Company” and together the “Target Companies” or “RPM”), pursuant to a Securities Purchase Agreement dated February 23, 2015 (the “Purchase Agreement”). Under the terms of the Purchase Agreement ExlService.com acquired all of the issued and outstanding limited liability company membership interests of the Target Companies (the “Securities”) from the security holders of each of the Target Companies. The initial purchase consideration consisted of $46,925 in cash including working capital adjustments of $75, contingent cash consideration of up to $23,000, as described below, and 122,131 restricted shares of common stock of the Company. There are no adjustments to the purchase price related to the financial performance of the Target Companies for 2014. The purchase agreement allows sellers the ability to earn up to an additional $23,000 (the “earn-out”) based on the achievement of certain performance goals by the Target Companies during the 2015 and 2016 calendar years.

Accordingly, the Company paid a premium for the acquisition which is being reflected in the goodwill recognized from the purchase price allocation of the total consideration paid by the Company. The Company made a preliminary allocation of the purchase price to the net tangible and intangible assets based on their fair values as mentioned below: Amount (In thousands) Net tangible assets $ 2,133 Identifiable intangible assets: Customer Relationship 13,260 Trade Names 1,520 Developed Technology 1,400 Non-Compete Agreements 680 Goodwill 30,776 Total purchase price* $ 49,769 * Includes amount of $4,125 deposited in escrow accounts in connection with the acquisition. The customer relationships from the RPM acquisition are being amortized over the weighted average useful life of 5.7 years. Similarly, trade-names are being amortized over a useful life of 3 years and developed technology and non-compete agreements are being amortized over a useful life of 5 years each. Under ASC topic 805, “Business Combinations,” the preliminary allocation of the purchase price to the tangible and intangible assets and liabilities acquired may change up to a period of one year from the date of the acquisition. The Company’s purchase accounting as of June 30, 2015 was incomplete and the Company expects to complete its valuation of the tangible assets, intangible assets and liabilities assumed as of the acquisition date during the third quarter. Accordingly, the Company may adjust the amounts recorded as of June 30, 2015 to reflect the final valuations of the assets acquired or liabilities assumed. During the six months ended June 30, 2015 the Company recognized $303 of acquisition related costs. Such amounts are included in general and administrative expenses in the consolidated statements of income.

Derivative Instruments and Hedging Activities Disclosure [Abstract]
Derivatives and Hedge Accounting	7. Derivatives and Hedge Accounting The Company uses derivative instruments and hedging transactions to mitigate exposure to foreign currency fluctuation risks associated with forecasted transactions denominated in certain foreign currencies and to minimize earnings and cash flow volatility associated with changes in foreign currency exchange rates. The Company’s derivative financial instruments are largely forward foreign exchange contracts that are designated effective and that qualify as cash flow hedges under ASC topic 815, “ Derivatives and hedging The Company had outstanding foreign exchange contracts totaling $295,684 and GBP 14,883 as of June 30, 2015 and totaling $276,018 and GBP 10,889 as of December 31, 2014. The Company estimates that approximately $1,100 of net derivative gains included in accumulated other comprehensive loss (“AOCI”) could be reclassified into earnings within the next twelve months based on exchange rates prevailing as of June 30, 2015. As of June 30, 2015, the maximum outstanding term of derivative instruments that hedge forecasted transactions was forty-five months. The Company evaluates the hedge effectiveness at the time a contract is entered into as well as on an ongoing basis. If during this time a contract is deemed ineffective, the change in the fair value is recorded in the unaudited consolidated statements of income and is included in foreign exchange loss. For hedging positions that are discontinued because the forecasted transaction is not expected to occur by the end of the originally specified period, any related derivative amounts recorded in equity are reclassified to earnings. No significant amounts of gains or losses were reclassified from AOCI into earnings during the three and six months ended June 30, 2015 and 2014.

Income Taxes	13. 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 of $5,531 and a benefit of $944 for the three months ended June 30, 2015 and 2014, respectively. Income tax expense for the six months ended June 30, 2015 and 2014 was $11,744 and $3,521, respectively. The effective tax rate increased from a negative 13.8% during the three months ended June 30, 2014 to 31.4% during the three months ended June 30, 2015. The increase in effective tax rate is primarily due to reversal of an unrecognized tax benefit of $2,173 and lower income in the U.S. due to reimbursement of disentanglement costs to Travelers during the three months ended June 30, 2014. The effective rate of taxes increased from 15.7% during the six months ended June 30, 2014 to 35.2% during the six months ended June 30, 2015. The increase in effective tax rate was primarily due to immaterial errors related to prior years (individually as well as when aggregated) which was recorded during the six months ended June 30, 2015, and resulted in an increase in income tax expense of approximately $1,800 (including $1,285 related to the taxability of certain foreign income in those prior years for which the Company recorded a reserve for an unrecognized tax benefit). The effective tax rate further increased during the six months ended June 30, 2015 due to reversal of an unrecognized tax benefit of $2,173 during the six months ended June 30, 2014, lower income in the U.S. due to reimbursement of disentanglement costs to Travelers and the expiration of a tax holiday in the Company’s operating centers in the Philippines and India. In accordance with ASC Topic 250, Accounting Changes and Error Corrections, the Company evaluated the effects of the errors on its financial statements for those prior years and the expected full year financial results for the year ending December 31, 2015 and concluded that the results of operations for these periods are not materially misstated. In reaching its conclusion, the Company considered qualitative and quantitative factors. The following table summarizes the activity related to the gross unrecognized tax benefits from January 1, 2015 through June 30, 2015: Balance as of January 1, 2015 $ 2,761 Increases related to prior year tax positions 1,239 Decreases related to prior year tax positions — Increases related to current year tax positions — Decreases related to current year tax positions — Effect of exchange rate changes (17 ) Balance as of June 30, 2015 $ 3,983 The unrecognized tax benefits as of June 30, 2015 of $3,983, if recognized, would impact the effective tax rate. During the three months ended June 30, 2015 and 2014, the Company has recognized interest of $52 and $55 respectively, which are included in the income tax expense in the unaudited consolidated statements of income. As of June 30, 2015 and December 31, 2014, the Company has accrued approximately $1,258 and $1,117, respectively in interest relating to unrecognized tax benefits.

Commitments and Contingencies Disclosure [Abstract]
Commitments and Contingencies	16. Commitments and Contingencies Fixed Asset Commitments As of June 30, 2015, the Company had committed to spend approximately $2,709 under agreements to purchase fixed assets. This amount is net of capital advances paid in respect of these purchases. Other Commitments Certain units of the Company’s Indian subsidiaries were established as 100% export-oriented units or under the Software Technology Parks of India (“STPI”) scheme promulgated by the Government of India. These units are exempt from customs, central excise duties, and levies on imported and indigenous capital goods, stores, and spares. The Company has undertaken to pay custom duties, service taxes, levies, and liquidated damages payable, if any, in respect of imported and indigenous capital goods, stores and spares consumed duty free, in the event that certain terms and conditions are not fulfilled. The Company’s management believes, however, that these units have in the past satisfied and will continue to satisfy the required conditions. The Company’s operations centers in the Philippines are registered with the Philippine Economic Zone Authority (“PEZA”). The registration provides the Company with certain fiscal incentives on the import of capital goods and requires Exl Philippines to meet certain performance and investment criteria. The Company’s management believes that these centers have in the past satisfied and will continue to satisfy the required criteria. Contingencies U.S. and Indian transfer pricing regulations require that any international transaction involving associated enterprises be at an arm’s length price. Accordingly, the Company determines the appropriate pricing for the international transactions among its associated enterprises on the basis of a detailed functional and economic analysis involving benchmarking against transactions among entities that are not under common control. The tax authorities have jurisdiction to review this arrangement and in the event that they determine that the transfer price applied was not appropriate, the Company may incur increased tax liability, including accrued interest and penalties. The Company is currently involved in disputes with the Indian tax authorities over the application of some of its transfer pricing policies for some of its subsidiaries. Further, the Company and its U.S. subsidiary, ExlService.com LLC are engaged in tax litigation with the income-tax authorities in India on the issue of permanent establishment. The aggregate disputed amount demanded by Indian tax authorities from the Company related to its transfer pricing issues for various years ranging from tax years 2003 to 2011 and its permanent establishment issues ranging from tax years 2003 to 2011 as of June 30, 2015 and December 31, 2014 is $19,847 and $22,866, respectively, of which the Company has already made payments or provided bank guarantees to the extent of $15,149 and $14,666, respectively. Amounts paid as deposits in respect of such assessments aggregating to $13,067 and $12,564 as of June 30, 2015 and December 31, 2014, respectively, are included in “Other assets” and amounts deposited for bank guarantees aggregating to $2,082 and $2,102 as of June 30, 2015 and December 31, 2014, respectively, are included in “Restricted cash” in the non-current assets section of the Company’s unaudited consolidated balance sheet as of June 30, 2015 and consolidated balance sheet as of December 31, 2014. Based on advice from its Indian tax advisors, the facts underlying the Company’s position and its experience with these types of assessments, the Company believes that the probability that it will ultimately be found liable for these assessments is remote and accordingly has not accrued any amount with respect to these matters in its consolidated financial statements. The Company does not expect any impact from these assessments on its future income tax expense. It is possible that the Company might receive similar orders or assessments from tax authorities for subsequent years. Accordingly even if these disputes are resolved, the Indian tax authorities may still serve additional orders or assessments.

Organization, Consolidation and Presentation of Financial Statements [Abstract]
Basis of Presentation	Basis of Presentation The unaudited interim consolidated financial statements have been prepared in accordance with U.S. generally accepted accounting principles (“US GAAP”) for interim financial information, the instructions to Form 10-Q and Article 10 of Regulation S-X. Form 10-K The unaudited interim 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	Principles of Consolidation The accompanying unaudited consolidated financial statements include the financial statements of ExlService Holdings and all of its subsidiaries. All intercompany balances and transactions have been eliminated in consolidation.
Use of Estimates	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, service tax receivables, assets and obligations related to employee benefit plans, deferred tax valuation allowances, income-tax uncertainties and other contingencies, valuation of derivative financial instruments, stock-based compensation expense, depreciation and amortization periods, purchase price allocation, recoverability of long-term assets including goodwill and intangibles, and estimates to complete the fixed price contracts. In accordance with its policy, the Company reviews the estimated useful lives of its fixed assets on an ongoing basis. This review indicated that the actual lives of certain fixed assets were longer than the estimated useful lives used for depreciation purposes in the Company’s financial statements. As a result, effective January 1, 2015, the Company changed its estimates of the useful lives of its certain fixed assets to better reflect the estimated periods during which these assets will remain in service. The effect of change in estimated useful life of assets reduced depreciation expense by $468 and $935, increased net income by $281 and $561 and increased basic and diluted earnings per share by $0.01 and $0.02, respectively during the three months and six months ended June 30, 2015.
Revenue Recognition	Revenue Recognition As part of reimbursing the Travelers Indemnity Company (“Travelers”) for certain of their transition related expenses (the “disentanglement costs”), the Company recognized $5,718 and $8,189 of such reimbursements as a reduction of our revenues during the three months and six months ended June 30, 2014 respectively, in accordance with Accounting Standards Codification topic 605-50-45, “Revenue Recognition.” The Company did not incur any reimbursements of disentanglement costs during the three months and six months ended June 30, 2015 and also does not anticipate incurring any additional reimbursements of disentanglement costs related to Travelers going forward. Revenue from analytical services including modeling, targeting and designing of campaigns and mail marketing including email marketing and other digital solutions is typically recognized on delivery of such campaigns. In respect of arrangements involving sub-contracting of part or whole of the assigned work, the Company evaluates revenue to be recognized under ASC 605-45 “Revenue recognition – Principal agent considerations”.
Investments	Investments The Company’s investments consist primarily of time deposits and mutual funds and are in accordance with the Company’s risk management policies. Time deposits with financial institutions are valued at cost and approximate fair value. Interest earned on such investments is included in interest and other income. Investments with original maturities greater than ninety days but less than twelve months are classified as short-term investments. Investments with maturities greater than twelve months from the balance sheet date are classified as long-term investments. The mutual fund investments are in debt and money market funds which invest in instruments of various maturities in India. The Company accounts for these investments in accordance with the fair value option under ASC topic 825-10 (“ASC No. 825-10”) and change in fair value is included in interest and other income. The fair value represents original cost (on the acquisition date) and the net asset value (“NAV”) as quoted, at each reporting period. Gain or loss on the disposal of these investments is calculated using the weighted average cost of the investments sold or disposed and is included in interest and other income.
Accrued expenses and other current liabilities	Accrued expenses and other current liabilities Accrued expenses and other current liabilities consist of the following: June 30, December 31, 2015 2014 Accrued expenses $ 27,095 $ 24,451 Derivative instruments 1,281 2,385 Client liability account 2,983 9,241 Other current liabilities 6,212 4,129 Accrued expenses and other current liabilities $ 37,571 $ 40,206

There were no such unrealized / realized gain/(loss) for the three months and six months ended June 30, 2014.
Recent Accounting Pronouncements	Recent Accounting Pronouncements In May 2014, the Financial Accounting Standards Board (“FASB”) issued ASU No. 2014-09, “Revenue from Contracts with Customers” (“ASU 2014-09”). Earlier the new standard was effective for reporting periods beginning after December 15, 2016. However, in April 2015, FASB deferred the effective date of the new standard. With this deferral, the new standard is effective for reporting periods beginning after December 15, 2017 and early adoption is not permitted. The comprehensive new standard will supersede existing revenue recognition guidance and require revenue to be recognized when promised goods or services are transferred to customers in amounts that reflect the consideration to which the Company expects to be entitled in exchange for those goods or services. Adoption of the new rules could affect the timing of revenue recognition for certain transactions of the Company. ASU 2014-09 is effective for the Company in the first quarter of fiscal 2018 using either one of two methods: (i) retrospectively to each prior reporting period presented with the option to elect certain practical expedients as defined within ASU 2014-09; or (ii) retrospectively with the cumulative effect of initially applying ASU 2014-09 recognized at the date of initial application and providing certain additional disclosures as defined per ASU 2014-09. The Company is currently evaluating the impact of adoption and the implementation approach to be used. In April 2015, FASB issued ASU No. 2015-05, “Intangibles – Goodwill and Other – Internal-Use Software (Subtopic 350-40): Customer’s Accounting for Fees Paid in a Cloud Computing Arrangement” (“ASU 2015-05”). The amendments add guidance to Subtopic 350-40, Intangibles – Goodwill and Other – Internal-Use Software, which will help entities evaluate the accounting for fees paid by a customer in a cloud computing arrangement. The amendments will be effective for fiscal years beginning after December 15, 2015. The Company is currently evaluating the method of adoption and impact this standard will have on its consolidated financial statements and related disclosures. In April 2015, FASB issued ASU No. 2015-03, “Interest—Imputation of Interest” (“ASU 2015-03”), which requires that debt issuance costs related to a recognized debt liability be presented in the balance sheet as a direct deduction from the carrying amount of that debt liability, consistent with debt discounts. The recognition and measurement guidance of debt issuance costs are not affected by the amendments in that update. The standard will be effective for the Company beginning in the first quarter of fiscal year 2016 and requires the Company to apply the new guidance on a retrospective basis on adoption. The adoption of this guidance is not expected to have any impact on the Company’s consolidated financial statements. In May 2015, FASB issued ASU No. 2015-08, “Business Combinations (Topic 805): Pushdown Accounting - Amendments to SEC Paragraphs Pursuant to Staff Accounting Bulletin No. 115” (“ASU 2015-08”). The amendments in ASU 2015-08 amend various SEC paragraphs included in FASB’s Accounting Standards Codification to reflect the issuance of Staff Accounting Bulletin No. 115 (“SAB 115”). SAB 115 rescinds portions of the interpretive guidance included in the SEC’s Staff Accounting Bulletins series and brings existing guidance into conformity with ASU No. 2014-17, “Business Combinations (Topic 805): Pushdown Accounting,” which provides an acquired entity with an option to apply pushdown accounting in its separate financial statements upon occurrence of an event in which an acquirer obtains control of the acquired entity. The adoption of this guidance does not have a material impact on the Company’s consolidated financial statements.
Business Combinations, Goodwill and Intangible Assets	RPM Direct LLC and RPM Data Solutions, LLC On March 20, 2015 ExlService.com completed its acquisition of RPM Direct LLC and RPM Data Solutions, LLC (each a “Target Company” and together the “Target Companies” or “RPM”), pursuant to a Securities Purchase Agreement dated February 23, 2015 (the “Purchase Agreement”). Under the terms of the Purchase Agreement ExlService.com acquired all of the issued and outstanding limited liability company membership interests of the Target Companies (the “Securities”) from the security holders of each of the Target Companies. The initial purchase consideration consisted of $46,925 in cash including working capital adjustments of $75, contingent cash consideration of up to $23,000, as described below, and 122,131 restricted shares of common stock of the Company. There are no adjustments to the purchase price related to the financial performance of the Target Companies for 2014. The purchase agreement allows sellers the ability to earn up to an additional $23,000 (the “earn-out”) based on the achievement of certain performance goals by the Target Companies during the 2015 and 2016 calendar years. The earn-out has an estimated fair value of $2,844. As noted above, the Company issued 122,131 restricted shares of common stock with an aggregate fair value of $4,150 to certain key members of the Target Companies, each of whom have accepted employment positions with the Company upon consummation of the combination. The Company also granted 113,302 restricted stock units with an aggregate fair value of $3,850 to certain employees of Target Companies, who have also accepted employment with the Company. The fair value of these grants will be recognized as compensation expense over the vesting period. RPM, now as a subsidiary of the Company, specializes in analyzing large consumer data sets to segment populations, predict response rates, forecast customer lifetime value and design targeted, multi-channel marketing campaigns. RPM has focused on the insurance industry, including P&C, life and health, since its inception in 2001. RPM maintains its own database and supports data on over 250 million consumers and 120 million U.S. households. The quantity and combination of data attributes managed by RPM drives optimal, data-driven decision-making and enables it to build models that analyze prospects individually. RPM employs proprietary predictive analytics and domain-specific pattern recognition algorithms to deliver results through a flexible, on-demand service model. Accordingly, the Company paid a premium for the acquisition which is being reflected in the goodwill recognized from the purchase price allocation of the total consideration paid by the Company. The Company made a preliminary allocation of the purchase price to the net tangible and intangible assets based on their fair values as mentioned below: Amount (In thousands) Net tangible assets $ 2,133 Identifiable intangible assets: Customer Relationship 13,260 Trade Names 1,520 Developed Technology 1,400 Non-Compete Agreements 680 Goodwill 30,776 Total purchase price* $ 49,769 * Includes amount of $4,125 deposited in escrow accounts in connection with the acquisition. The customer relationships from the RPM acquisition are being amortized over the weighted average useful life of 5.7 years. Similarly, trade-names are being amortized over a useful life of 3 years and developed technology and non-compete agreements are being amortized over a useful life of 5 years each. Under ASC topic 805, “Business Combinations,” the preliminary allocation of the purchase price to the tangible and intangible assets and liabilities acquired may change up to a period of one year from the date of the acquisition. The Company’s purchase accounting as of June 30, 2015 was incomplete and the Company expects to complete its valuation of the tangible assets, intangible assets and liabilities assumed as of the acquisition date during the third quarter. Accordingly, the Company may adjust the amounts recorded as of June 30, 2015 to reflect the final valuations of the assets acquired or liabilities assumed. During the six months ended June 30, 2015 the Company recognized $303 of acquisition related costs. Such amounts are included in general and administrative expenses in the consolidated statements of income. The Company’s results of operations for the three and six months ended June 30, 2015 includes revenues of $10,319 and $11,511, respectively for RPM since March 20, 2015, the date on which the acquisition was consummated. It is not practicable to disclose the net earnings since management does not allocate or evaluate operating expenses and income taxes to its domestic entities. The amount of goodwill recognized from the RPM acquisition is deductible for tax purposes. Goodwill The following table sets forth details of the Company’s goodwill balance as of June 30, 2015: Operations Analytics and Total Balance at January 1, 2014 $ 90,622 $ 16,785 $ 107,407 Goodwill arising from Blue Slate acquisition — 4,554 4,554 Goodwill arising from Overland acquisition 28,667 — 28,667 Currency translation adjustments (529 ) — (529 ) Allocation on sale of a business unit (1) (500 ) — (500 ) Balance at December 31, 2014 $ 118,260 $ 21,339 $ 139,599 Goodwill arising from RPM acquisition — 30,776 30,776 Currency translation adjustments (246 ) — (246 ) Balance at June 30, 2015 $ 118,014 $ 52,115 $ 170,129 (1) Relates to the sale of a business unit (acquired with the Business Process Outsourcing Inc. acquisition) during the year ended December 31, 2014.

Intangible Assets Information regarding the Company’s intangible assets is as follows: As of June 30, 2015 Gross Accumulated Net Carrying Customer relationships $ 64,850 $ (20,272 ) $ 44,578 Leasehold benefits 2,899 (2,089 ) 810 Developed technology 12,214 (3,354 ) 8,860 Non-compete agreements 2,045 (1,371 ) 674 Trade names and trademarks 6,510 (2,472 ) 4,038 $ 88,518 $ (29,558 ) $ 58,960 As of December 31, 2014 Gross Accumulated Net Carrying Customer relationships $ 51,598 $ (16,836 ) $ 34,762 Leasehold benefits 2,927 (2,004 ) 923 Developed technology 10,814 (2,402 ) 8,412 Non-compete agreements 1,365 (1,323 ) 42 Trade names and trademarks 4,990 (2,150 ) 2,840 $ 71,694 $ (24,715 ) $ 46,979 Amortization expense for the three months ended June 30, 2015 and 2014 was $2,808 and $1,489, respectively. Amortization expense for the six months ended June 30, 2015 and 2014 was $4,867 and $3,025, respectively. The weighted average life of intangible assets was 8.8 years for customer relationships, 8.0 years for leasehold benefits, 6.5 years for developed technology, 4.5 years for non-compete agreements and 5.9 years for trade names and trademarks excluding indefinite life trade names and trademarks. The Company had $900 of indefinite life trade names and trademarks as of June 30, 2015 and December 31, 2014. Estimated amortization of intangible assets during the year ending June 30, 2016 $ 11,159 2017 $ 11,152 2018 $ 10,832 2019 $ 10,404 2020 $ 6,288 2021 and thereafter $ 8,225
