Accounting Policies [Abstract]
Description of Business and Summary of Significant Accounting Policies	Description of Business and Summary of Significant Accounting Policies Description of Business— Ebix, Inc., and its subsidiaries, (“Ebix” or the “Company”) is a leading international supplier of on-demand infrastructure Exchanges to the insurance, financial, and healthcare industries. In the Insurance sector, the Company’s main focus is to develop and deploy a wide variety of insurance and reinsurance exchanges on an on-demand basis, while also providing SaaS enterprise solutions in the area of CRM, front-end & back-end systems, outsourced administrative and risk compliance.

The Company has its headquarters in Johns Creek, Georgia and also conducts operating activities in Australia, Canada, India, New Zealand, Singapore, United Kingdom, Brazil, Philippines, Indonesia, and United Arab Emirates. International revenue accounted for 41.8% , 28.4% , and 22.7% of the Company’s total revenue in 2017 , 2016 , and 2015 , respectively. The Company’s revenues are derived from four product/service groups. Presented in the table below is the breakout of our revenue streams for each of those product/service groups for the years ended December 31, 2017 , 2016 and 2015 . For the Year Ended December 31, (dollar amounts in thousands) 2017 2016 2015 Exchanges $ 259,470 $ 206,427 $ 190,746 Broker P&C Systems 14,674 14,105 14,481 RCS 86,832 74,196 55,917 Carrier P&C Systems 2,995 3,566 4,338 Totals $ 363,971 $ 298,294 $ 265,482 The Company is continuing to evaluate the classification of the 2017 acquisitions that collectively make up the EbixCash Financial Exchanges, refer to Part I, Item I Business. Currently they are reported under Exchange channel, but is subject to change based on the conclusions of our evaluations. Summary of Significant Accounting Policies Basis of Presentation — The consolidated financial statements include the accounts of Ebix and its wholly owned subsidiaries. The effect of inter-company balances and transactions has been eliminated. Use of Estimates —The preparation of consolidated financial statements in conformity with accounting principles generally accepted in the United States of America ("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 dates of the financial statements and reported amounts of revenue and expenses during those reporting periods. Management has made material estimates primarily with respect to revenue recognition and deferred revenue, accounts receivable, acquired intangible assets, annual impairment reviews of goodwill, indefinite-lived intangible assets, investments, contingent earnout liabilities in connection with business acquisitions, and the provision for income taxes. Actual results may be materially different from those estimates. Reclassification —As part of the Wdev acquisition $2.9 million of the upfront cash consideration is being held in an escrow account for the thirty-eight month period following the effective date of the acquisition to ensure that the acquired business achieves the minimum specified annual net revenue threshold, which if not achieved will result in said funds being returned to Ebix. This amount which was previously reported in "Restricted Cash" on our December 31, 2016 condensed consolidated balance sheets, is now being reported in "Other Assets" line in the long term asset section of the condensed consolidated balance sheets. Additionally, as of December 31, 2016 there was $14.4 million of restricted fiduciary funds associated with the EbixHealth JV that pertain to un-remitted insurance premiums and claim funds established for the benefit of various carriers which are held in a fiduciary capacity until disbursed. This amount which was previously reported in "Restricted Cash" on our December 31, 2016 condensed consolidated balance sheets, is now being reported in "Fiduciary funds restricted" line in the short term asset section of the condensed consolidated balance sheets Segment Reporting —Since the Company, from the perspective of its chief operating decision maker, allocates resources and evaluates business performance as a single entity that provides software and related services to various industries on a worldwide basis, the Company reports as a single segment. The applicable enterprise-wide disclosures are included in Note 14. Cash and Cash Equivalents —The Company considers all highly liquid investments with an original maturity of three months or less at the time of purchase to be cash equivalents. Such investments are stated at cost, which approximates fair value. The Company does maintain cash balances in banking institutions in excess of federally insured amounts and therefore is exposed to the related potential credit risk associated with such cash deposits. Short-term Investments —The Company’s primary short-term investments consist of certificates of deposits with established commercial banking institutions in India that have readily determinable fair values. Ebix accounts for such investments that are reasonably expected to be realized in cash, sold or consumed during the year as short-term investments that are available-for-sale. The carrying amount of investments in marketable securities approximates their fair value. The carrying value of our short-term investments was $25.59 million and $3.11 million at December 31, 2017 and 2016 , respectively. Restricted Cash —As part of Ebix entering into a joint venture with India-based Essel Group, while acquiring an 80% stake in ItzCash $4.0 million of the possible future contingent earn-out payments is being held in escrow accounts for the twelve month period following the effective date of the acquisition to ensure that the acquired business achieves the minimum specified annual gross revenue threshold, which if not achieved will result in said funds being returned to Ebix. The carrying value of our restricted cash was $4.0 million and zero at December 31, 2017 and 2016 respectively. Fiduciary Funds - Restricted —Due to the EbixHealth JV being a third party administrator (“TPA”), the Company collects premiums from insureds and, after deducting its fees, remits these premiums to insurance companies. Unremitted insurance premiums and/or claim funds established for the benefit of various carriers are held in a fiduciary capacity until disbursed by the Company. The use of premiums collected from insureds but not yet remitted to insurance companies is restricted by law in certain states. The total assets held on behalf of others, $8.0 million , are recorded as an asset and offsetting fiduciary funds - restricted liability. Fair Value Measurements —The Company follows the relevant GAAP guidance regarding the determination and measurement of the fair value of assets/liabilities in which fair value is defined as the exchange price that would be received for an asset or paid to transfer a liability (an exit price) in the principal or most advantageous market for the asset or liability in an orderly transaction valuation hierarchy which requires an entity to maximize the use of observable inputs when measuring fair value. The guidance describes the following three levels of inputs that may be used in the methodology to measure fair value: • Level 1 — Quoted prices available in active markets for identical investments as of the reporting date; • Level 2 — Inputs other than quoted prices in active markets, which are either directly or indirectly observable as of the reporting date; and, • Level 3 — Unobservable inputs, which are to be used in situations where there is little or no market activity for the asset or liability and wherein the reporting entity makes estimates and assumptions related to the pricing of the asset or liability including assumptions regarding risk. A financial instrument’s level within the fair value hierarchy is based on the lowest level of any input that is significant to the fair value measurement. As of December 31, 2017 and 2016 the Company has the following financial instruments to which it had to consider fair values and had to make fair assessments: • Short-term investments (commercial bank certificates of deposits and mutual funds), for which the fair values are measured as a Level 1 instrument. • Contingent accrued earn-out business acquisition consideration liabilities for which fair values are measured as Level 3 instruments. These contingent consideration liabilities were recorded at fair value on the acquisition date and are remeasured periodically based on the then assessed fair value and adjusted if necessary. The increases or decreases in the fair value of contingent consideration payable can result from changes in anticipated revenue levels or changes in assumed discount periods and rates. As the fair value measure is based on significant inputs that are not observable in the market, they are categorized as Level 3. Other financial instruments not measured at fair value on the Company's consolidated balance sheets at December 31, 2017 and 2016 but which require disclosure of their fair values include: cash and cash equivalents, accounts receivable, accounts payable and accrued expenses, accrued payroll and related benefits, capital lease obligations, and debt under the credit facility with Regions Bank. The estimated fair value of such instruments at December 31, 2017 and 2016 reasonably approximates their carrying value as reported on the consolidated balance sheets.

The discount rate used in these calculations is 13.5% . Significant increases (decreases) in these unobservable inputs in isolation would likely result in a significantly (lower) higher fair value measurement. Revenue Recognition and Deferred Revenue —The Company derives its revenues primarily from professional and support services, which includes revenue generated from subscription and transaction fees pertaining to services delivered over our exchanges or from our application service provider (“ASP”) platforms, software development projects and associated fees for consulting, implementation, training, and project management provided to customers using our systems, and risk compliance solutions ("RCS"). Sales and value-added taxes are not included in revenues, but rather are recorded as a liability until the taxes assessed are remitted to the respective taxing authorities. The Company follows the relevant technical accounting guidance regarding revenue recognition as issued by the Financial Accounting Standards Board ("FASB") and the Securities and Exchange Commission ("SEC"). The Company considers revenue earned and realizable when: (a) persuasive evidence of the sales arrangement exists, (b) the arrangement fee is fixed or determinable, (c) service delivery or performance has occurred, (d) customer acceptance has been received or is reasonably assured, if contractually required, and (e) collectability of the arrangement fee is probable. The Company typically uses signed contractual agreements, purchase orders, or statements of work as persuasive evidence of a sales arrangement. We apply the provisions of the relevant FASB accounting pronouncements related to all transactions involving the license of software where the software deliverables are considered more than inconsequential to the other elements in the arrangement. For contracts that contain multiple deliverables, we analyze the revenue arrangements in accordance with the appropriate authoritative guidance, which provides criteria governing how to determine whether goods or services that are delivered separately in a bundled sales arrangement should be considered as separate units of accounting for the purpose of revenue recognition. Deliverables are accounted for separately if they meet all of the following criteria: a) the delivered item has value to the customer on a stand-alone basis; b) there is objective and reliable evidence of the fair value for all arrangement deliverables; and c) if the arrangement includes a general right of return relative to the delivered items, the delivery or performance of the undelivered items is probable and substantially controlled by the Company. Under the relevant accounting guidance, when multiple-deliverables included in an arrangement are to be separated into different units of accounting, the arrangement consideration is allocated to the identified separate units of accounting based on their relative fair values. We determine the relative selling price for a deliverable based on vendor-specific objective evidence of selling price (“VSOE”), if available, or third-party evidence ("TPE") in the alternative if available, or finally our best estimate of selling price (“BESP”), if VSOE or TPE is not available. The Company begins to recognize revenue from license fees for its exchange (SAAS) and ASP products upon granting customer access to the respective processing platform. Transaction services fee revenue for this use of our exchanges or ASP platforms is recognized as the transactions occur and is generally billed in arrears. Revenues from RCS arrangements, which include data entry and call center services, and insurance certificate creation and tracking services, are recognized as the services are performed. Revenues from RCS consulting arrangements are recognized as the services are delivered on a time and materials basis. Service fees for hosting arrangements are recognized over the requisite service period. Revenue derived from the licensing of third party software products in connection with sales of the Company’s software licenses is recognized upon delivery together with the Company’s licensed software products. Fees for training, data conversion, installation, and consulting services fees are recognized as revenue when the services are performed. Revenues for maintenance and support services are recognized ratably over the term of the support agreement. Software development arrangements involving significant customization, modification or production are accounted for in accordance with the appropriate technical accounting guidance issued by the FASB using the percentage-of-completion method. The Company recognizes revenue using periodic reported actual hours worked as a percentage of total expected hours required to complete the project arrangement and applies the percentage to the total arrangement fee. Financial exchange revenue consists largely of transaction-based fees and fees from corporate and retail gift vouchers. The transaction-based fees are primarily based on a percentage of payment value processed for solutions such as retail and corporate payments, domestic money transfers, and general purpose reloadable cards. Transaction-based fees are recognized at the completion of the transaction. Gift voucher revenue is recognized at full purchase value at time of sale with the corresponding cost of vouchers recorded under direct expenses. Deferred revenue includes payments or billings that have been received or made prior to performance and, in certain cases, cash collections and primarily pertain to maintenance and support fees, initial setup or registration fees under hosting agreements, software license fees received in advance of delivery and acceptance, and software development fees paid in advance of completion and delivery. Approximately $5.2 million and $6.0 million of deferred revenue were included in billed accounts receivable at December 31, 2017 and 2016 , respectively. Accounts Receivable and the Allowance for Doubtful Accounts Receivable —Reported accounts receivable as of December 31, 2017 include $94.5 million of trade receivables stated at invoice billed amounts and $23.3 million of unbilled receivables (net of a $4.1 million estimated allowance for doubtful accounts receivable). Reported accounts receivable at December 31, 2016 include $51.8 million of trade receivables stated at invoice billed amounts and $10.9 million of unbilled receivables (net of a $2.8 million estimated allowance for doubtful accounts receivable). The unbilled receivables pertain to certain professional service engagements and system development projects for which the timing of billing is tied to contractual milestones . The Company is continuing to evaluate the 2017 acquisitions that collectively make up the EbixCash Financial Exchanges, refer to Part I, Item I Business, and their impact on our condensed consolidated balance sheets. The Company adheres to suc h contractually stated performance milestones and accordingly issues invoices to customers as per contract billing schedules. Accounts receivable are written off against the allowance for doubtful accounts receivable when the Company has exhausted all reasonable co llection efforts. Management specifically analyzes the aging of accounts receivable and historical bad debts, write-offs, customer concentrations, customer credit-worthiness, current economic trends, and changes in our customer payment patterns when evaluating the adequacy of the allowance for doubtful accounts receivable. Bad debt expense was $1.7 million , $1.5 million , and $3.1 million for the year ended December 31, 2017 , 2016 , and 2015 , respectively. Costs of Services Provided —Costs of services provided consist of data processing costs, customer support costs including personnel costs to maintain our proprietary databases, costs to provide customer call center support, hardware and software expense associated with transaction processing systems and exchanges, telecommunication and computer network expense, and occupancy costs associated with facilities where these functions are performed. Depreciation expense is not included in costs of services provided. Capitalized Software Development Costs —In accordance with the relevant FASB accounting guidance regarding the development of software to be sold, leased, or marketed, the Company expenses such costs as they are incurred until technological feasibility has been established, at and after which time those costs are capitalized until the product is available for general release to customers. Costs incurred to enhance our software products, after general market release of the services using the products, is expensed in the period they are incurred. The periodic expense for the amortization of previously capitalized software development costs is included in costs of services provided. Goodwill and Indefinite-Lived Intangible Assets —Goodwill represents the cost in excess of the fair value of the identifiable net assets from the businesses that we acquire. In accordance with the relevant FASB accounting guidance, goodwill is tested for impairment at the reporting unit level on an annual basis or on an interim basis if an event occurred or circumstances change that would indicate that fair value of a reporting unit decreased below its carrying value. Potential impairment indicators include a significant change in the business climate, legal factors, operating performance indicators, competition, customer retention and the sale or disposition of a significant portion of the business. The Company applies the technical accounting guidance concerning goodwill impairment evaluation whereby the Company first assesses certain qualitative factors to determine whether the existence of events or circumstances would indicate that it is more likely than not that the fair value of any of our reporting units was less than its carrying amount. If after assessing the totality of events and circumstances, we were to determine that it is more likely than not that the fair value of a reporting unit is less than its carrying amount, then we would perform the two-step quantitative impairment testing described further below. The aforementioned two-step quantitative testing process involves comparing the reporting unit carrying values to their respective fair values; we determine fair value of our reporting units by applying the discounted cash flow method using the present value of future estimated net cash flows. If the fair value of a reporting unit exceeds its carrying value, then no further testing is required. However, if a reporting unit’s fair value were to be less than its carrying value, we would then determine the amount of the impairment charge, if any, which would be the amount that the carrying value of the reporting unit’s goodwill exceeded its implied value. We perform our annual goodwill impairment evaluation and testing as of September 30 each year. In 2017 the goodwill residing in the Broker Systems reporting unit, was evaluated for impairment based on an assessment of certain qualitative factors, and was determined not to have been impaired. In 2017 the goodwill residing in the Exchange reporting unit, the RCS reporting unit, and the Carrier reporting unit were evaluated for impairment using step-one of the quantitative testing process described above. The fair value of both of these reporting units were found to be greater than their carrying value, and thusly there was no need to proceed to step-two, as there was no impairment indicated. In specific regards to the Risk Compliance Solutions reporting unit, its assessed fair value was $158.0 million which was $42.4 million or 36.7% in excess of its $115.6 million carrying value. Key assumptions used in the fair value determination were annual revenue growth rates of 7.5% to 12.5% and discount rate of 16% . As of September 30, 2017 there was $78.2 million of goodwill assigned to the RCS reporting unit. A significant reduction in future revenues for the RCS reporting unit would negatively affect the fair value determination for this unit and may result in an impairment to goodwill and a corresponding charge against earnings. During the years ended December 31, 2017, 2016, and 2015, we had no impairment of any our reporting unit goodwill balances. Projections of cash flows are based on our views of revenue growth rates, operating costs, anticipated future economic conditions, the appropriate discount rates relative to risk, and estimates of residual values and terminal values. We believe that our estimates are consistent with assumptions that marketplace participants would use in their estimates of fair value. The use of different estimates or assumptions for our projected discounted cash flows (e.g., revenue growth rates, future economic conditions, discount rates, and estimates of terminal values) when determining the fair value of our reporting units could result in different values and may result in a goodwill impairment charge. As a practice, the Company closely monitors any reporting units that do not have a significantly higher fair value in excess of their carrying value. The following table summarizes the adjustments to goodwill, recorded in connection with the acquisitions, that occurred during 2017 and 2016 : Company acquired Date acquired (in thousands) Oakstone; final purchase allocation adjustments December 2014 $ 948 EbixHealth JV; final purchase allocation adjustments July 2016 (7,500 ) Hope Health; final purchase allocation adjustments November 2016 (289 ) Wdev; final purchase allocation adjustments November 2016 (5,317 ) ItzCash April 2017 119,766 beBetter June 2017 447 YouFirst September 2017 7,395 Wall Street October 2017 6,113 Paul Merchants November 2017 38,589 Via November 2017 60,785 Total changes to goodwill during 2017 $ 220,937 PB Systems; final purchase allocation adjustments June 2015 $ 4,298 EbixHealth JV July 2016 20,839 Hope Health November 2016 1,333 Wdev November 2016 13,615 Total changes to goodwill during 2016 $ 40,085 Changes in the carrying amount of goodwill for the years ended December 31, 2017 and 2016 are as follows: December 31, 2017 December 31, 2016 (in thousands) Beginning Balance $ 441,404 $ 402,259 Additions for current year acquisitions 233,095 35,787 Purchase accounting adjustments for prior year acquisitions (12,158 ) 4,298 Foreign currency translation adjustments 4,522 (940 ) Ending Balance $ 666,863 $ 441,404 The Company’s indefinite-lived assets are associated with the estimated fair value of the contractual customer relationships existing with the property and casualty insurance carriers in Australia using our property and casualty ("P&C") data exchange and with certain large corporate customers using our client relationship management (“CRM”) platform in the United States. Prior to these underlying business acquisitions Ebix had pre-existing contractual relationships with these carriers and corporate clients. The contracts are renewable at little or no cost, and Ebix intends to continue to renew these contracts indefinitely and has the ability to do so. The proprietary technology supporting the P&C data exchange and CRM platform that is used to deliver services to these carriers and corporate clients, cannot feasibly be effectively replaced in the foreseeable future, and accordingly the cash flows forthcoming from these customers are expected to continue indefinitely. With respect to the determination of the indefinite life, the Company considered the expected use of these intangible assets, historical experience in renewing or extending similar arrangements, and the effects of competition, and concluded that there were no indications from these factors to suggest that the expected useful life of these customer relationships would be finite. The Company concluded that no legal, regulatory, contractual, or competitive factors limited the useful life of these intangible assets and therefore their life was considered to be indefinite, and accordingly the Company expects these customer relationships to remain the same for the foreseeable future. Additionally based on the final purchase price allocation valuation report of the EbixHealth JV, See Note 3 and 17 for further explanations, it was concluded that the value of the indefinite-lived intangibles identified as indefinite-lived customer relationships to be $11.2 million . The EbixHealth JV is a full-service third-party administrator (“TPA”) that specializes in the management, administration, and distribution of health benefit plans. Services include marketing support, underwriting, billing, claims processing, and cost containment such as utilization review and medical case management for fully-insured, self-funded and partially self-funded benefit plans, as well as international groups and individuals. As a TPA, the Company collects premiums from insureds and, after deducting its fees, remits these premiums to insurance companies. Unremitted insurance premiums and/or claim funds established for the benefit of various carriers are held in a fiduciary capacity until disbursed by the Company. The Company administers and collects the insurance premiums for the products of three affiliated insurance carriers which is part of the consolidated company IHC Health Holdings Corporation ("IHC") a 49% shareholder of the EbixHealth JV. The administrative agreements with the three affiliates accounted for approximately 83% of revenues for the year ended December 31, 2017. IHC is therefore considered a major customer of the EbixHealth JV and therefore considered indefinite-lived. The churn expected for indefinite-lived customers is assumed at 0% . The fair values of these indefinite-lived intangible assets were based on

Earnings Per Share [Abstract]
Earnings per Share	Earnings per Share The basic and diluted earnings per share (“EPS”), and the basic and diluted weighted average shares outstanding for all periods as presented in the accompanying Consolidated Statements of Income are shown below: For the year ended December 31, (In thousands, except per share amounts) Earnings per share: 2017 2016 2015 Basic earnings per common share $ 3.19 $ 2.88 $ 2.29 Diluted earnings per common share $ 3.17 $ 2.86 $ 2.28 Basic weighted average shares outstanding 31,552 32,603 34,668 Diluted weighted average shares outstanding 31,719 32,863 34,901 Basic EPS is equal to net income attributable to Ebix, Inc divided by the weighted average number of shares of common stock outstanding for the period. Diluted EPS takes into consideration common stock equivalents which for the Company consist of stock options and restricted stock. With respect to stock options, diluted EPS is calculated as if the Company had additional common stock outstanding from the beginning of the year or the date of grant or issuance, net of assumed repurchased shares using the treasury stock method. Diluted EPS is equal to net income attributable to Ebix, Inc divided by the combined sum of the weighted average number of shares outstanding and common stock equivalents. At December 31, 2017 , 2016 , and 2015 there were no potentially issuable shares with respect to stock options which could dilute EPS in the future but which were excluded from the diluted EPS calculation because presently their effect is anti-dilutive. Diluted shares outstanding are determined as follows for each year ending December 31, 2017 , 2016 , and 2015 : For the year ended December 31, (in thousands) 2017 2016 2015 Basic weighted average shares outstanding 31,552 32,603 34,668 Incremental shares for common stock equivalents 167 260 233 Diluted shares outstanding 31,719 32,863 34,901

Business Acquisitions

Business Acquisitions	12 Months Ended

Business Combinations [Abstract]
Business Acquisitions	Business Acquisitions The Company’s business acquisitions are accounted for under the purchase method of accounting in accordance with the FASB’s accounting guidance on the accounting for business combinations. Accordingly, the consideration paid by the Company for the businesses it purchases is allocated to the tangible and intangible assets and liabilities acquired based upon their estimated fair values as of the date of the acquisition. The excess of the purchase price over the estimated fair values of assets acquired and liabilities assumed is recorded as goodwill. Recognized goodwill pertains in part to the value of the expected synergies to be derived from combining the operations of the businesses we acquire including the value of the acquired workforce. While we use our best estimates and assumptions to accurately value assets acquired and liabilities assumed at the acquisition date as well as contingent consideration, where applicable, our estimates are inherently uncertain and subject to refinement. As a result, during the measurement period, which may be up to one year from the acquisition date, we may record significant adjustments to the assets acquired and liabilities assumed with the corresponding offset to goodwill. Upon the conclusion of the measurement period or final determination of the values of assets acquired or liabilities assumed, whichever comes first, any subsequent adjustments are recognized in our consolidated statements of operations. The Company's practice is to immediately tightly integrate all functions including infrastructure, sales and marketing, administration, product development after a business acquisition is consummated, so as to ensure that synergistic efficiencies are maximized and redundancies eliminated, and to rapidly leverage cross-selling opportunities. Furthermore the Company centralizes certain key functions such as information technology, marketing, sales, human resources, finance, and other general administrative functions after an acquisition, in order and to quickly realize cost efficiencies. By executing this integration strategy it becomes neither practical nor feasible to accurately and separately track and disclose the earnings from the business combinations we have executed after they have been acquired. A significant component of the purchase price consideration for many of the Company's business acquisitions is a potential future cash earnout based on reaching certain specified future revenue targets. The terms for the contingent earn-out payments in most of the Company's business acquisitions typically address the GAAP recognizable revenues achieved by the acquired entity over a one, two, and/or three year period subsequent to the effective date of their acquisition by Ebix. These terms typically establish a minimum threshold revenue target with achievement of revenues recognized over that target being awarded in the form of a specified cash earn-out payment. The Company applies these terms in its calculation and determination of the fair value of contingent earn-out liabilities for purchased businesses as part of the related valuation and purchase price allocation exercise for the corresponding acquired assets and liabilities. The Company recognizes these potential obligations as contingent liabilities as reported on its Consolidated Balance Sheets. As discussed in more detail in Note 1, these contingent consideration liabilities are recorded at fair value on the acquisition date and are remeasured quarterly based on the then assessed fair value and adjusted if necessary. During each of the years ending December 31, 2017 , 2016 and 2015 , respectively, these aggregate contingent accrued earn-out business acquisition consideration liabilities, were reduced by $164 thousand , $1.3 million and $1.5 million , respectively, due to remeasurements as based on the then assessed fair value and changes in the amount and timing of anticipated future revenue levels. These reductions to the contingent accrued earn-out liabilities resulted in corresponding reduction to general and administrative expenses as reported on the Consolidated Statements of Income. As of December 31, 2017 , the total of these contingent liabilities was $37.1 million , of which $33.1 million is reported in long-term liabilities, and $4.0 million is included in current liabilities in the Company's Consolidated Balance Sheet. As of December 31, 2016 the total of these contingent liabilities was $8.5 million of which $6.6 million was reported in long-term liabilities, and $1.9 million was included in current liabilities in the Company's Consolidated Balance Sheet. 2017 Acquisitions Via - Effective November 1, 2017 Ebix acquired Via, a recognized leader in the travel space in India and an Omni-channel online travel and assisted e-commerce exchange.

Ebix acquired PB Systems for upfront cash consideration in the amount of $12.4 million , plus possible future contingent earn-out payments of up to $8.0 million based on earned revenues over the subsequent twenty-four month period following the effective date of the acquisition. The Company initially accounted for this acquisition by recording $6.8 million of goodwill, and $10.3 million of intangible assets pertaining to customer relationships. In the Company's Form 10-K for the year ended December 31, 2015, the Company had disclosed that the valuation and purchase price allocation for the PB Systems acquisition was preliminary because all of the information necessary to determine the fair value of the acquired customer relationship intangible asset and fair value of the revenue-based earn-out contingent liability was still in the process of being evaluated by management and the Company's external valuation firms. This evaluation was completed during the second quarter ended June 30, 2016 and based on this the final goodwill and intangible assets pertaining to customer relationships recorded were $11.2 million and $2.1 million , respectively. The changes that resulted were a $(8.2) million reduction to the customer relationship intangible asset, a $(3.2) million reduction to the deferred tax liability, a $(664) thousand reduction to the revenue-based earn-out contingent liability, and a corresponding and offsetting $4.3 million increase to goodwill. The Company has determined that the fair value of the contingent earn-out consideration is zero as of December 31, 2017.

Pro Forma Financial Information [Abstract]
Pro Forma Financial Information (re: 2014 and 2013 acquisitions)	Pro Forma Financial Information (re: 2017 and 2016 acquisitions) This unaudited pro forma financial information is provided for informational purposes only and does not project the Company’s results of operations for any future period. The aggregated unaudited pro forma financial information pertains to all of the Company's acquisitions made during 2017 and 2016, which includes the acquisitions of the ItzCash, YouFirst, Wall Street, Paul Merchants,Via, the acquisition of assets of beBetter in 2017, and the acquisition of Wdev, the acquisition of assets of Hope Health , taking a controlling position in the EbixHealth JV with IHC in 2016 as presented in the table below, and is provided for informational purposes only and does not project the Company's expected results of operations for any future period. No effect has been given in this pro forma information for future synergistic benefits that may still be realized as a result of combining these companies or costs that may yet be incurred in integrating their operations. The 2017 and 2016 pro forma financial information below assumes that all such business acquisitions were made on January 1, 2016, whereas the Company's reported financial statements for 2017 only includes the operating results from the businesses since the effective date that they were acquired by Ebix, and thusly includes only nine months of ItzCash, seven months of beBetter, four months of YouFirst, three months of Wall Street, two months of Paul Merchants, and two months of Via. Similarly, the 2016 pro forma financial information below includes a full year of results for Wdev, Hope Health, and EbixHealth JV as if they had been acquired on January 1, 2016, whereas the Company's reported financial statements for the 2016 includes only two months of Wdev, two months of Hope Health, and six months of the EbixHealth JV. As Reported 2017 Pro Forma 2017 As Reported 2016 Pro Forma 2016 (unaudited) (unaudited) (In thousands, except per share amounts) Revenue $ 363,971 $ 440,512 $ 298,294 $ 434,152 Net income attributable to Ebix, Inc. $ 100,618 $ 104,851 $ 93,847 $ 96,147 Basic EPS $ 3.19 $ 3.32 $ 2.88 $ 2.95 Diluted EPS $ 3.17 $ 3.31 $ 2.86 $ 2.93 In the above table, the unaudited pro forma revenue for the year ended December 31, 2017 increased by $6.4 million from the unaudited pro forma revenue for 2016 of $434.2 million to $440.5 million , representing a 1.5% increase, with the change in exchange rates postively affecting reported revenues by $2.1 million . The reported revenue in the amount of $364.0 million for the year ended December 31, 2017 increased by $65.7 million or 22.0% from the $298.3 million of reported revenue for the year ended December 31, 2016 . The cause for the difference between the 22.0% increase in reported 2017 revenue versus 2016 revenue, as compared to the 1.5% increase in 2017 pro forma versus 2016 pro forma revenue is due to the effect of combining the additional revenue derived from those businesses acquired during the years 2017 and 2016, specifically ItzCash, YouFirst, Wall Street, Paul Merchants,Via, beBetter, Wdev, Hope Health, and the EbixHealth JV with the Company's pre-existing operations. The 2017 and 2016 pro forma financial information assumes that all such business acquisitions were made on January 1, 2016, whereas the Company's reported financial statements for 2017 only includes the operating results from the businesses since the effective date that they were acquired by Ebix, and thus includes only nine months of ItzCash, seven months of beBetter, four months of YouFirst, three months of Wall Street, two months of Paul Merchants, and two months of Via. The above pro forma analysis is based on the following premises: • 2017 and 2016 pro forma revenue contains actual revenue of the acquired entities before acquisition date, as reported by the sellers, as well as actual revenue of the acquired entities after acquisition. Growth in revenues of the acquired entities after acquisition date is only reflected for the period after their acquisition. • Revenue billed to existing clients from the cross selling of acquired products has been assigned to the acquired section of our business. • Any existing products sold to new customers acquired through the acquisition customer base, has also been assigned to the acquired section of our business. • The impact from fluctuations of the exchange rates for the foreign currencies in the countries in which we conduct operations also partially affected reported revenues. During each of the years 2017 and 2016 the change in foreign currency exchange rates increased (decreased) reported consolidated operating revenues by $2.1 million and $(3.3) million , respectively.

The Credit Agreement also contains an accordion feature, which if exercised and approved by all credit parties, would expand the total borrowing capacity under the syndicated credit facility to $500 million . The credit facility carries a leverage-based LIBOR related interest rate, which currently stands at approximately 4.125% . Effective October 14, 2015 the Company, in coordination with Regions as administrative agent and a joint lender, exercised the $50 million accordion feature in the Credit agreement thereby expanding the total credit facility to $240 million . As part of this credit facility expansion, TD Bank, NA ("TD") was added to the syndication group expanding the syndicated group to five bank participants, which include Regions, MUFG Union Bank N.A., Fifth Third Bank, and Silicon Valley Bank as joint lenders. TD commitment level is $25 million . The expanded credit facility will continue to be used to fund the Company's future growth and share repurchase initiatives. On February 3, 2015, Ebix, Inc. and certain of its subsidiaries entered into the First Amendment (the “First Amendment”) to the Credit Agreement. The First Amendment amends the Regions Credit Facility by increasing the maximum amount by which the Aggregate Revolving Commitments may be increased by $90 million from the pre-existing limit of $50 million , increased the amount of base facility to $190 million from the pre-existing amount of $150 million , which together with the $50 million accordion feature increased the total Credit Agreement capacity amount to $240 million from the prior amount of $200 million , and added Fifth Third Bank to the syndicated group, which now includes four participants, which include Regions, MUFG Union Bank N.A., and Silicon Valley Bank as joint lenders. At December 31, 2017 , the outstanding balance on the revolving line of credit with Regions was $274.5 million and the facility carried an interest rate of 4.125% .

Commitments and Contingencies Disclosure [Abstract]
Commitments and Contingencies	Commitments and Contingencies Contingencies - Following the announcement on May 1, 2013 of the Company's execution of a merger agreement with affiliates of Goldman Sachs & Co., twelve putative class action complaints challenging the proposed merger were filed in the Delaware Court of Chancery. These complaints named as Defendants some combination of the Company, its directors, Goldman Sachs & Co. and affiliated entities. On June 10, 2013, the twelve complaints were consolidated by the Delaware Court of Chancery, now captioned In re Ebix, Inc. Stockholder Litigation, CA No. 8526-VCS. On June 19, 2013, the Company announced that the merger agreement had been terminated pursuant to a Termination and Settlement Agreement dated June 19, 2013. After Defendants moved to dismiss the consolidated proceeding, Plaintiffs Desert States Employers & UFCW Union Pension Plan and Gilbert C. Spagnola (collectively, “Lead Plaintiffs”) amended their operative complaint to drop their claims against Goldman Sachs & Co. and focus their allegations on an Acquisition Bonus Agreement (“ABA”) between the Company and Robin Raina. On September 26, 2013, Defendants moved to dismiss the Amended Consolidated Complaint. On July 24, 2014, the Court issued its Memorandum Opinion that granted in large part the Company’s Motion to Dismiss and narrowed the remaining claims. On September 15, 2014, the Court entered an Order implementing its Memorandum Opinion. On January 16, 2015, the Court entered an Order permitting Plaintiffs to file a Second Amended and Supplemented Complaint. On February 10, 2015, Defendants filed a Motion to Dismiss the Second Amended and Supplemented Complaint, which was granted in part and denied in part in a January 15, 2016 Memorandum Opinion and Order. On October 25, 2016, the Court entered an Order permitting Lead Plaintiffs to file a Verified Third Amended and Supplemented Class Action and Derivative Complaint, which made additional claims and added two directors as defendants. The Verified Third Amended and Supplemented Class Action and Derivative Complaint was then filed on October 26, 2016. On October 31. 2016, Lead Plaintiffs filed a Motion for Class Certification. On November 1, 2016, Lead Plaintiffs moved for partial summary judgment on Claims (ii), (iii), and (vi) as described below. The directors added as defendants in the Third Amended and Supplemented Class Action and Derivative Complaint moved to dismiss all Claims against them. The remaining Defendants moved to dismiss certain Claims, and filed answers to the other claims in the Verified Third Amended and Supplemented Complaint. On December 12, 2017, the Court postponed the pending hearing on the Plaintiffs’ Motion for Class Certification and the Defendants’ motions to dismiss and, instead, granted the Plaintiffs leave to file a Verified Fourth Amended and Supplemented Class Action and Derivative Complaint, which pleading was filed on January 19, 2018. The claims in the fourth amended complaint are as follows: (i) a purported class and derivative claim for breach of fiduciary duty for improperly maintaining the ABA as an unreasonable anti-takeover device; (ii) a purported class claim for breach of the fiduciary duty of disclosure to the stockholders with respect to the Company’s 2010 Proxy Statement and 2010 Stock Incentive Plan; (iii) a purported derivative claim for breach of fiduciary duty to the Company in causing incentive compensation to be awarded under the 2010 Stock Incentive Plan; (iv) a purported class and derivative claim for breach of fiduciary duty in adopting certain bylaw amendments on December 19, 2014; (v) a purported class and derivative claim seeking invalidation of the December 19, 2014 bylaw amendments under Delaware law; (vi) a purported claim for breach of fiduciary duty for not duly adopting the ABA at the July 15, 2009 Board meeting, and seeking declaratory relief invalidating the ABA; (vii) a purported claim for breach of the fiduciary duty of disclosure to the stockholders with respect to the ABA, and seeking declaratory relief invalidating the ABA; (viii) a purported claim seeking invalidation of the 2008 Stockholder Meeting, 2008 Certificate Amendment, 2008 Stock Split and subsequent corporate actions; (ix) a purported class claim for breach of fiduciary duty, and seeking declaratory relief invalidating the 2016 CEO Bonus Plan because of incomplete disclosures with respect to the ABA; and (x) for breach of fiduciary duty and declaratory judgment relating to the interpretation of the ABA. Lead Plaintiffs seek declaratory relief with respect to the ABA, the 2010 Stock Incentive Plan, the 2010 Proxy Statement, the bylaw amendments, the 2008 Stockholder Meeting, the 2008 Certificate Amendment, the 2008 Stock Split, and the 2016 CEO Bonus Plan. Lead Plaintiffs also seek compensatory damages, interest, and attorneys’ fees and costs, all in unspecified amounts. A trial is scheduled for August 2018. The Company denies any liability and intends to defend the action vigorously. The Company is involved in various other claims and legal actions arising in the ordinary course of business. In the opinion of management, the ultimate likely disposition of these matters will not have a material adverse effect on the Company’s consolidated financial position, results of operations or liquidity. Lease Commitments— The Company leases office space under non-cancelable operating leases with expiration dates ranging through 2029, with various renewal options. Capital leases range from three to five years and are primarily for computer equipment. There were multiple assets under various individual capital leases at December 31, 2017 and 2016 . Commitments for minimum rentals under non-cancellable leases, debt obligations, and future purchase obligations as of December 31, 2017 were as follows: Year Debt Capital Leases Operating Leases Future Purchase Obligations (in thousands) 2018 $ 14,500 $ 20 $ 6,937 $ 541 2019 14,500 20 4,835 406 2020 14,500 8 3,015 — 2021 356,779 — 1,847 — 2022 — — 1,209 — Thereafter — — 1,828 — Total $ 400,279 $ 48 $ 19,671 $ 947 Less: sublease income (2,215 ) Net lease payments $ 17,456 Less: amount representing interest (5 ) Present value of obligations under capital leases $ 43 Less: current portion (14,500 ) (17 ) Long-term obligations $ 385,779 $ 26 Rental expense for office facilities and certain equipment subject to operating leases for 2017 , 2016 , and 2015 was $6.6 million , $6.4 million and $6.5 million , respectively. Sublease income for 2017 , 2016 and 2015 was $1.1 million , $977 thousand , and $580 thousand , respectively. Business Acquisition Earn-out Contingencies— A significant component of the purchase price consideration for many of the Company's business acquisitions is a potential future cash earnout based on reaching certain specified future revenue targets. The terms for the contingent earn-out payments in most of the Company's business acquisitions typically address the GAAP recognizable revenues achieved by the acquired entity over a one, two, and/or three year period subsequent to the effective date of their acquisition by Ebix. These terms typically establish a minimum threshold revenue target with achievement of revenues recognized over that target being awarded in the form of a specified cash earn-out payment. The Company applies these terms in its calculation and determination of the fair value of contingent earn-out liabilities for purchased businesses as part of the related valuation and purchase price allocation exercise for the corresponding acquired assets and liabilities. As of December 31, 2017 , the total of these contingent liabilities was $37.1 million , of which $33.1 million is reported in long-term liabilities, and $4.0 million is included in current liabilities in the Company's Consolidated Balance Sheet. As of December 31, 2016 the total of these contingent liabilities was $8.5 million of which $6.6 million was reported in long-term liabilities, and $1.9 million was included in current liabilities in the Company's Consolidated Balance Sheet. Self -Insurance— For some of the Company’s U.S. employees the Company is currently self-insured for its health insurance program and has a stop loss policy that limits the individual liability to $120 thousand per person and the aggregate liability to 125% of the expected claims based upon the number of participants and historical claims. As of December 31, 2017 and 2016 , the amount accrued on the Company’s consolidated balance sheet for the self-insured component of the Company’s employee health insurance was $332 thousand and $346 thousand , respectively. The maximum potential estimated cumulative liability for the annual contract period, which ends in September 2018, is $2.8 million .

No stock options were granted to employees or non-employees during 2017 , 2016 and 2015 ; however, options were granted to Directors in 2017 and 2015. Stock compensation expense of $433 thousand , $340 thousand and $294 thousand was recognized during the years ending December 31, 2017 , 2016 and 2015 , respectively, on outstanding and unvested options. The fair value of options granted during 2017 is estimated on the date of grant using the Black-Scholes option pricing model. The following table includes the weighted- average assumptions used in estimating the fair values and the resulting weighted-average fair value of stock options granted in the periods presented: Year Ended December 31, 2017 Year Ended December 31, 2016 Year Ended December 31, 2015 Weighted average fair values of stock options granted $ 15.38 $ 19.50 $ 7.90 Expected volatility 37.9 % 55.5 % 55.4 % Expected dividends .56 % .61 % 1.42 % Weighted average risk-free interest rate 1.64 % 1.40 % 1.03 % Expected life of stock options (in years) 3.5 3.5 3.5 A summary of stock option activity for the years ended December 31, 2017 , 2016 and 2015 is as follows: Shares Weighted Average Exercise Price Weighted Average Remaining Contractual Term (Years) Aggregate Intrinsic Value (in thousands) Outstanding at January 1, 2015 207,000 $ 16.41 1.88 $ 121 Granted 42,000 $ 22.25 Exercised (109,122 ) $ 20.25 Canceled — Outstanding at December 31, 2015 139,878 $ 15.17 2.32 $ 2,465 Granted 42,000 $ 49.22 Exercised (72,379 ) $ 11.38 Canceled — Outstanding at December 31, 2016 109,499 $ 30.73 3.28 $ 2,882 Granted 42,000 $ 53.90 Exercised (3,500 ) $ 14.90 Canceled — Outstanding at December 31, 2017 147,999 $ 37.68 2.94 $ 6,152 Exercisable at December 31, 2017 71,499 $ 26.65 2.02 $ 3,761 The aggregate intrinsic value for stock options outstanding and exercisable is defined as the difference between the market value of the Company’s stock as of the end of the period and the exercise price of the stock options.

Beginning in 2009, we were granted a 100% tax holiday for certain of our Indian operations, which was in effect until March 31, 2014 and March 31, 2015 for some of our locations and continues until March 31, 2020 for other locations. When these tax holidays expire, these locations become 50% taxable for an additional five years. The impact of this tax holiday decreased our non-US income tax expense by $2.9 million and $13.7 million for 2017 and 2016, respectively. The Company’s consolidated worldwide effective tax rate is relatively low because of the effect of conducting significant operations in certain foreign jurisdictions, specifically India, Dubai, and Singapore, where we have tax holidays or tax concessions. Deferred tax assets and liabilities are comprised of the following: December 31, 2017 December 31, 2016 Deferred Deferred Assets Liabilities Assets Liabilities (In thousands) Depreciation and amortization $ 683 $ — $ 95 $ — Share-based compensation 590 1,612 Accruals and prepaids 2,700 842 Bad debts 1,076 859 Acquired intangible assets — 19,421 — 22,508 Net operating loss carryforwards 15,233 19,019 Tax credit carryforwards (primarily MAT in India) 43,044 35,514 63,326 19,421 57,941 22,508 Valuation allowance (35 ) — (3,747 ) — Total deferred taxes $ 63,291 $ 19,421 $ 54,194 $ 22,508 Amounts recognized in the consolidated balance sheets: 2017 2016 (In thousands) Non-current deferred tax assets 43,870 31,686 ASU 2013-11 reclass, described below (341 ) (341 ) Net deferred tax assets 43,529 31,345 The valuation allowance changed by ($3.7) million and $(2.2) million during the years ended December 31, 2017 and 2016, respectively. The presentation above has been modified to correctly show the valuation allowances that should have been recorded and to gross up the Company’s deferred tax assets for implied valuation allowances that were inherited through acquisitions. We have US Federal, state and foreign operating losses and credit carryforwards as follows: Year Ended December 31, 2017 Year Ended December 31, 2016 (In thousands) US Federal loss carryforwards $ 42,981 $ 47,796 US state loss carryforwards 25,186 15,535 Foreign loss carryforwards 29,852 25,849 US Federal credit carryforwards 4,679 1,235 Foreign credit carryforwards 38,364 34,278 The US federal and state operating loss carryforwards expire at varying dates through 2038. The federal credits begin to expire in 2018. We also have non-US loss carryforwards of approximately $29.9 million as of December 31, 2017 , the majority of which may be carried forward indefinitely. We released the valuation allowance on our UK entity in the current year due to recent and projected profitability. On December 22, 2017, the Tax Cuts and Jobs Act (“TCJA”) was enacted, substantially changing the U.S. tax system and affecting the Company in a number of ways. Notably, the TCJA: establishes a flat corporate income tax rate of 21.0% on U.S. earnings; imposes a one-time tax on unremitted cumulative non-U.S. earnings of foreign subsidiaries (“Transition Tax”);imposes a new minimum tax on certain non-U.S. earnings, irrespective of the territorial system of taxation, and generally allows for the repatriation of future earnings of foreign subsidiaries without incurring additional U.S. taxes by transitioning to a territorial system of taxation; subjects certain payments made by a U.S. company to a related foreign company to certain minimum taxes (Base Erosion Anti-Abuse Tax); eliminates certain prior tax incentives for manufacturing in the United States and creates an incentive for U.S. companies to sell, lease or license goods and services abroad by allowing for a reduction in taxes owed on earnings related to such sales; allows the cost of investments in certain depreciable assets acquired and placed in service after September 27, 2017 to be immediately expensed; and reduces deductions with respect to certain compensation paid to specified executive officers. While the changes from the TCJA are generally effective beginning in 2018, U.S. GAAP accounting for income taxes requires the effect of a change in tax laws or rates to be recognized in income from continuing operations for the period that includes the enactment date. Due to the complexities involved in accounting for the enactment of the TCJA, the SEC Staff Accounting Bulletin No. 118 (“SAB No. 118”) allowed the Company to record provisional amounts in earnings for the year ended December 31, 2017. Where reasonable estimates can be made, the provisional accounting should be based on such estimates. When no reasonable estimate can be made, the provisional accounting may be based on the tax law in effect before the TCJA. The Company is required to complete its tax accounting for the TCJA within a one-year period when it has obtained, prepared, and analyzed the information to complete the income tax accounting. Due to insufficient guidance, as well as the availability of information to accurately analyze the impact of the TCJA, we have made a reasonable estimate of the effects, as described below, and in other cases we have not been able to make a reasonable estimate and continue to account for those items based on our existing accounting under FASB ASC Topic 740, Income Taxes and the provisions of the tax laws that were in effect immediately prior to enactment. U.S. deferred tax assets and liabilities were remeasured based on the rates at which they are expected to reverse in the future, which is generally 21.0% , resulting in an income tax benefit of approximately $2.5 million . As we complete our analysis, collect and prepare necessary data, and interpret any additional regulatory or accounting guidance, the Company may make adjustments to the provisional amounts we have recorded during a measurement period of up to one year from the enactment of the TCJA that could impact our provision for income taxes in the reporting period in which we make such adjustments. The Transition Tax is based on the Company’s total post-1986 earnings and profits that were previously deferred from U.S. income taxes. The Company has not recorded an amount for the Transition Tax expense, as they do not have the necessary information to determine a reasonable estimate to include as a provisional amount. The Company will work to gather the necessary information to calculate the transition tax and will record the impact of this in the reporting period when the analysis is complete. The Company has not recognized a deferred U.S. tax liability and associated income tax expense for the undistributed earnings of its foreign subsidiaries which we consider indefinitely invested because those foreign earnings will remain permanently reinvested in those subsidiaries to fund ongoing operations and growth. Upon distribution of those earnings in the form of dividends or otherwise, we would be subject to income taxes and withholding taxes payable in various jurisdictions, which could potentially be partially offset by foreign tax credits. At December 31, 2017 the cumulative amount of the Company’s undistributed foreign earnings was approximately $523.3 million , inclusive of income previously taxed in the United States. The following table summarizes the activity related to our unrecognized tax benefits: December 31, 2017 December 31, 2016 December 31, 2015 (in thousands) Beginning Balance $ 3,265 $ 3,115 $ 3,020 Additions for tax positions related to current year — 43 41 Additions for tax positions of prior years 5,879 107 131 Reductions for tax position of prior years — — (77 ) Ending Balance $ 9,144 $ 3,265 $ 3,115 The Company recognizes interest accrued and penalties related to unrecognized tax benefits as part of income tax expense. Interest assessed upon settlement of a tax return position is classified as interest expense. The Company accrued as of December 31, 2017 and 2016 approximately $1.0 million and $771 thousand , respectively, of estimated interest and penalties. These amounts are included in the December 31, 2017 and 2016 balances in the preceding table of $9.1 million and $3.3 million , respectively, which is included in other long term liabilities in the accompanying Consolidated Balance Sheet. We file income tax returns in the US federal, many US state and local jurisdictions, and certain foreign jurisdictions. We have substantially resolved all US federal income tax matters for tax years prior to 2014. Our state and foreign tax matters may remain open from 2008 forward. The Company has applied the new provisions under Accounting Standards Update 2013-11, Presentation of an Unrecognized Tax Benefit When a Net Operating Loss Carryforward, A Similar Tax Loss, or a Tax Credit Carryforward Exists , or ASU 2013-11. Under these provisions, an unrecognized tax benefit is to be presented in the financial statements as a reduction to a deferred tax asset for a net operating loss carryforward. The Company has applied this provision and $341 thousand and $341 thousand of unrecognized tax benefits have been applied against the deferred tax assets for net operating loss carryforwards, as of December 31, 2017 and 2016 respectively.

Segment Reporting [Abstract]
Geographic Information	Geographic Information The Company operates with one reportable segment whose results are regularly reviewed by the Company's CEO, its chief operating decision maker as to operating performance and the allocation of resources. External customer revenues in the tables below were attributed to a particular country based on whether the customer had a direct contract with the Company which was executed in that particular country for the sale of the Company's products/services with an Ebix subsidiary located in that country. During 2017 India's revenue increased $47.7 million of which $5.3 million is due to the various new e-governance contracts with a number of large clients and $42.9 million due to its 2017 acquisitions of ItzCash, YouFirst, Wall Street, Paul Merchants, and Via. Latin America's revenues increased $12.9 million due primarily to the November 2016 acquisition of Wdev and a $1.4 million increase due to changes in foreign currency exchange rates. Australia's revenues increased by $3.2 million due to a combination of increased professional services and transaction fees, and a $1.1 million increase due to changes in foreign currency exchange rates. Canada's revenues increased by $1.2 million due primarily to increased professional services. Increases in Singapore, Indonesia, Philippines and United Arab Emirates are due to the November 2017 acquisition of Via. During 2016 the change in foreign currency exchange rates decreased reported Australian and Latin America operating revenues by $(410) thousand and $(300) thousand , respectively. India's 2016 operating revenues increased $10.6 million or 300% due primarily to the various new e-governance contracts with a number of large clients. Europe's revenues increased $8.8 million , net of $(2.2) million decrease due to changes in foreign currency exchange rates, due primarily to the execution and commencement of certain significant contracts.

The Europe increase of $3.9 million is primarily due to a 9.3% strengthening of the British Pound Sterling versus the U.S. Dollar which caused a $2.0 million increase in the translation of long-lived assets, an increase in deferred tax assets of $3.2 million due to the release of valuation allowances of operating loss carryforwards, partially offset by the amortization of intangible assets and capitalized software development costs. In the geographical information table above the significant changes to long-lived assets from December 31, 2015 to December 31, 2016 are explained as follows: the U.S. increase of $11.3 million is primarily comprised of a $14.6 million net increase due to the consolidation of the EbixHealth JV commensurate with the step up in ownership to 51% , partially offset by a $(4.7) million decrease of intangibles due to amortization; the Latin America increase of $17.7 million is due to the Wdev acquisition (for which the valuation and purchase accounting is preliminary); the Singapore decrease of $51.4 million and the Dubai increase of $54.2 million are due to the transfer of certain intangible assets between these locations (net of deferred taxes); the India increase of $8.4 million is primarily due an increase in deferred tax assets of $4.8 million associated with the payments and accruals of Minimum Alternative Tax, and $3.5 million of fixed assets additions associated with the continued build out of our product development facilities, and the growth of the Ebix-Vayam JV; the Europe decrease of $6.3 million is primarily due to a 16.6% weakening of British Pound Sterling versus the U.S. Dollar which caused a $4.3 million decrease in the translation of long-lived assets, partially offset by the amortization of intangible assets and capitalized software development costs.

Equity Method Investments and Joint Ventures [Abstract]
Investment in Joint Venture	Investment in Joint Ventures Effective April 1, 2017 Ebix entered into a joint venture with India-based Essel Group, while acquiring an 80% equity interest in ItzCash, India’s leading payment solutions exchange. ItzCash is recognized as a leader in the prepaid cards and bill payments space in India. Under the terms of the agreement, ItzCash was valued at a total enterprise value of approximately $150 million . Accordingly, Ebix acquired an 80% equity interest in ItzCash for $120 million including upfront cash of $76.3 million plus possible future contingent earn-out payments of up to $44.0 million based on earned revenues over the subsequent thirty-six month period following the effective date of the acquisition. $4.0 million of the possible future contingent earn-out payments is being held in escrow accounts for the twelve month period following the effective date of the acquisition to ensure that the acquired business achieves the minimum specified annual gross revenue threshold, which if not achieved will result in said funds being returned to Ebix. The valuation and purchase price allocation for the ItzCash acquisition remains preliminary and will be finalized as soon as practicable but in no event longer than one year from the effective date of the transaction. Effective February 7, 2016 Ebix and Vayam Technologies Ltd ("Vayam") formed a joint venture named Ebix Vayam Limited JV. This joint venture was established to carry out IT projects in the government sector of the country of India and particularly in regards to the implementation of e-governance projects in the areas of education and healthcare. Ebix has a 51% equity interest in the joint venture, and Vayam has a 49% equity interest in the joint venture. Ebix is fully consolidating the operations of the Ebix Vayam Limited JV into the Company's financial statements and separately reporting the Vayam minority, non-controlling, interest in the joint venture's net income and equity. Vayam is, also, a customer of the Ebix Vayam Limited JV, and during the twelve months ending December 31, 2017 and 2016 the Ebix Vayam Limited JV recognized $16.9 million and $11.6 million of revenue from Vayam, respectively, and as of December 31, 2017 Vayam had $26.8 million of accounts receivable with the Ebix Vayam Limited JV. Effective September 1, 2015 Ebix and IHC formed a joint venture named EbixHealth JV. This joint venture was established to promote and market a best practices administration data exchange for health and pet insurance lines of business nationally. Ebix paid $6.0 million and contributed certain portions of its CurePet investment, valued by the EbixHealth JV at $2.0 million , for its 40% membership interest in the EbixHealth JV. IHC contributed all if its shares in its existing third party administrator operations (IHC Health Solutions, Inc.), valued by the EbixHealth JV at $12.0 million for its 60% membership interest in the EbixHealth JV and received a special distribution of $6.0 million . As per the joint venture agreement, any and all losses of the EbixHealth JV, (excluding certain severance payments to former employees of IHC Health Solutions, Inc.) through the period ending December 31, 2016 will be allocated to IHC, and IHC is obligated to fund any negative cash flow during this period as a loan to the EbixHealth JV, with any remaining balance of said loan as of December 31, 2016 being then converted to contributed capital. Effective July 1, 2016 Ebix and IHC jointly executed a Call Notice agreement, whereby Ebix purchased additional common units in the EbixHealth JV from IHC constituting eleven percent ( 11% ) of the EbixHealth JV for $2.0 million cash which resulted in Ebix holding an aggregate fifty-one percent ( 51% ) of the EbixHealth JV. Commensurate with additional equity stake in the joint venture and a new contemporaneous valuation of the business the Company realized a $1.2 million gain on its previously carried 40% equity interest in the EbixHealth JV.

Concentration Risk [Line Items]
Concentration Risk Disclosure [Text Block]	Note 19. Concentrations of Credit Risk Credit Risk The Company is potentially subject to concentrations of credit risk in its accounts receivable. Credit risk is the risk of an unexpected loss if a customer fails to meet its contractual obligations. Although the Company is directly affected by the financial condition of its customers and the loss of or a substantial reduction in orders or the ability to pay from the customer could have a material effect on the consolidated financial statements, management does not believe significant credit risks exist at December 31, 2017. The Company had one customer whose accounts receivable balances individually represented 10% or more of the Company’s total accounts receivable. Major Customer As previously disclosed in Note 17, effective February 7, 2016 Ebix and Vayam Technologies Ltd ("Vayam") formed a joint venture named Ebix Vayam Limited JV. This joint venture was established to carry out IT projects in the government sector of the country of India and particularly in regards to the implementation of e-governance projects in the areas of education and healthcare. Ebix has a 51% equity interest in the joint venture, and Vayam has a 49% equity interest in the joint venture. Ebix is fully consolidating the operations of the Ebix Vayam Limited JV into the Company's financial statements and separately reporting the Vayam minority, non-controlling, interest in the joint venture's net income and equity. Vayam is also a customer of the Ebix Vayam Limited JV, and during the twelve months ending December 31, 2017 and 2016 the Ebix Vayam Limited JV recognized $16.9 million and $11.6 million of revenue from Vayam, respectively, and as of December 31, 2017 Vayam had $26.8 million of accounts receivable with the Ebix Vayam Limited JV.

Subsequent Events [Abstract]
Subsequent Events	Subsequent Events Amendment to Syndicated Commercial Banking Credit Agreement On February 21, 2018, Ebix, Inc. and certain of its subsidiaries entered into the Sixth Amendment (the “Sixth Amendment”) to the Credit Agreement. The Sixth Amendment amends the Regions Credit Facility by increasing its existing credit facility from $450 million to $650 million , to assist in funding its growth. The increase in the bank line was the result of many members of the existing bank group expanding their share of the credit facility and the addition of BBVA Compass and Bank Of The West to the Banking Syndicate, which further diversifies Ebix’s lending group under the credit facility to ten participants.The syndicated bank group now comprises ten leading financial institutions that include Regions Bank, PNC Bank, BMO Harris Bank, BBVA Compass, Fifth Third Bank, KeyBank, Bank Of The West, Silicon Valley Bank, Cadence Bank and Trustmark National Bank. Regions Bank continued to lead the banking group while serving as the administrative and collateral agent. PNC Bank and BMO Harris Bank were added as co syndication agents, BBVA Compass and Fifth Third Bank as co documentation agent, while Regions Capital Markets, PNC Capital Markets and BMO Harris Bank acted as joint lead arrangers and joint bookrunners. The new credit facility has the following key components; A five -year term loan for $250 million and a five -year revolving credit facility for $400 million . The new credit facility, also, allows for up to $150 million of incremental facilities. As of closing, the facility interest rates will be based on a leveraged-based pricing grid. Acquisitions On February 14, 2018 Ebix acquired the MTSS Business of Transcorp International Limited (BSE:TRANSCOR.BO), for upfront cash consideration of approximately $7.4 million , through one of its Indian subsidiaries. Ebix plans on consolidating this recent acquisition into Ebix's Financial Exchange operations which will bring significant synergies and the elimination of redundancies to the combined operation. Joint Venture Effective January 2, 2018 Paul Merchants acquired a 10% equity interest in Ebix’s combined international remittance business in India (comprised of YouFirst, Wall Street and Paul Merchants) for cash consideration of $5.0 million . The consolidation of these acquisitions into Ebix's Financial Exchange operations will bring significant synergies and the elimination of redundancies to the combined operation. As part of this agreement Ebix retains an irrevocable option to reacquire 10% of the equity interest after one year at a predetermined price. Dividends The Company plans to continue with its quarterly cash dividend to the holders of its common stock, whereby a dividend in the amount of $0.075 per common share will be paid on March 15, 2018 to shareholders of record on February 28, 2018.

Description of Business and S30

Description of Business and Summary of Significant Accounting Policies (Policies)	12 Months Ended
	Dec. 31, 2017
Accounting Policies [Abstract]
Basis of Presentation	Basis of Presentation — The consolidated financial statements include the accounts of Ebix and its wholly owned subsidiaries. The effect of inter-company balances and transactions has been eliminated.
Use of Estimates	Use of Estimates —The preparation of consolidated financial statements in conformity with accounting principles generally accepted in the United States of America ("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 dates of the financial statements and reported amounts of revenue and expenses during those reporting periods. Management has made material estimates primarily with respect to revenue recognition and deferred revenue, accounts receivable, acquired intangible assets, annual impairment reviews of goodwill, indefinite-lived intangible assets, investments, contingent earnout liabilities in connection with business acquisitions, and the provision for income taxes. Actual results may be materially different from those estimates.
Reclassification	Reclassification —As part of the Wdev acquisition $2.9 million of the upfront cash consideration is being held in an escrow account for the thirty-eight month period following the effective date of the acquisition to ensure that the acquired business achieves the minimum specified annual net revenue threshold, which if not achieved will result in said funds being returned to Ebix. This amount which was previously reported in "Restricted Cash" on our December 31, 2016 condensed consolidated balance sheets, is now being reported in "Other Assets" line in the long term asset section of the condensed consolidated balance sheets. Additionally, as of December 31, 2016 there was $14.4 million of restricted fiduciary funds associated with the EbixHealth JV that pertain to un-remitted insurance premiums and claim funds established for the benefit of various carriers which are held in a fiduciary capacity until disbursed. This amount which was previously reported in "Restricted Cash" on our December 31, 2016 condensed consolidated balance sheets, is now being reported in "Fiduciary funds restricted" line in the short term asset section of the condensed consolidated balance sheets
Segment Reporting	Segment Reporting —Since the Company, from the perspective of its chief operating decision maker, allocates resources and evaluates business performance as a single entity that provides software and related services to various industries on a worldwide basis, the Company reports as a single segment
Cash and Cash Equivalents	Cash and Cash Equivalents —The Company considers all highly liquid investments with an original maturity of three months or less at the time of purchase to be cash equivalents. Such investments are stated at cost, which approximates fair value. The Company does maintain cash balances in banking institutions in excess of federally insured amounts and therefore is exposed to the related potential credit risk associated with such cash deposits.
Short-term Investments	Short-term Investments —The Company’s primary short-term investments consist of certificates of deposits with established commercial banking institutions in India that have readily determinable fair values. Ebix accounts for such investments that are reasonably expected to be realized in cash, sold or consumed during the year as short-term investments that are available-for-sale. The carrying amount of investments in marketable securities approximates their fair value.
Fair Value of Financial Instruments	Fair Value Measurements —The Company follows the relevant GAAP guidance regarding the determination and measurement of the fair value of assets/liabilities in which fair value is defined as the exchange price that would be received for an asset or paid to transfer a liability (an exit price) in the principal or most advantageous market for the asset or liability in an orderly transaction valuation hierarchy which requires an entity to maximize the use of observable inputs when measuring fair value. The guidance describes the following three levels of inputs that may be used in the methodology to measure fair value: • Level 1 — Quoted prices available in active markets for identical investments as of the reporting date; • Level 2 — Inputs other than quoted prices in active markets, which are either directly or indirectly observable as of the reporting date; and, • Level 3 — Unobservable inputs, which are to be used in situations where there is little or no market activity for the asset or liability and wherein the reporting entity makes estimates and assumptions related to the pricing of the asset or liability including assumptions regarding risk. A financial instrument’s level within the fair value hierarchy is based on the lowest level of any input that is significant to the fair value measurement. As of December 31, 2017 and 2016 the Company has the following financial instruments to which it had to consider fair values and had to make fair assessments: • Short-term investments (commercial bank certificates of deposits and mutual funds), for which the fair values are measured as a Level 1 instrument. • Contingent accrued earn-out business acquisition consideration liabilities for which fair values are measured as Level 3 instruments. These contingent consideration liabilities were recorded at fair value on the acquisition date and are remeasured periodically based on the then assessed fair value and adjusted if necessary. The increases or decreases in the fair value of contingent consideration payable can result from changes in anticipated revenue levels or changes in assumed discount periods and rates. As the fair value measure is based on significant inputs that are not observable in the market, they are categorized as Level 3. Other financial instruments not measured at fair value on the Company's consolidated balance sheets at December 31, 2017 and 2016 but which require disclosure of their fair values include: cash and cash equivalents, accounts receivable, accounts payable and accrued expenses, accrued payroll and related benefits, capital lease obligations, and debt under the credit facility with Regions Bank. The estimated fair value of such instruments at December 31, 2017 and 2016 reasonably approximates their carrying value as reported on the consolidated balance sheets.
Revenue Recognition and Deferred Revenue	Revenue Recognition and Deferred Revenue —The Company derives its revenues primarily from professional and support services, which includes revenue generated from subscription and transaction fees pertaining to services delivered over our exchanges or from our application service provider (“ASP”) platforms, software development projects and associated fees for consulting, implementation, training, and project management provided to customers using our systems, and risk compliance solutions ("RCS"). Sales and value-added taxes are not included in revenues, but rather are recorded as a liability until the taxes assessed are remitted to the respective taxing authorities. The Company follows the relevant technical accounting guidance regarding revenue recognition as issued by the Financial Accounting Standards Board ("FASB") and the Securities and Exchange Commission ("SEC"). The Company considers revenue earned and realizable when: (a) persuasive evidence of the sales arrangement exists, (b) the arrangement fee is fixed or determinable, (c) service delivery or performance has occurred, (d) customer acceptance has been received or is reasonably assured, if contractually required, and (e) collectability of the arrangement fee is probable. The Company typically uses signed contractual agreements, purchase orders, or statements of work as persuasive evidence of a sales arrangement. We apply the provisions of the relevant FASB accounting pronouncements related to all transactions involving the license of software where the software deliverables are considered more than inconsequential to the other elements in the arrangement. For contracts that contain multiple deliverables, we analyze the revenue arrangements in accordance with the appropriate authoritative guidance, which provides criteria governing how to determine whether goods or services that are delivered separately in a bundled sales arrangement should be considered as separate units of accounting for the purpose of revenue recognition. Deliverables are accounted for separately if they meet all of the following criteria: a) the delivered item has value to the customer on a stand-alone basis; b) there is objective and reliable evidence of the fair value for all arrangement deliverables; and c) if the arrangement includes a general right of return relative to the delivered items, the delivery or performance of the undelivered items is probable and substantially controlled by the Company. Under the relevant accounting guidance, when multiple-deliverables included in an arrangement are to be separated into different units of accounting, the arrangement consideration is allocated to the identified separate units of accounting based on their relative fair values. We determine the relative selling price for a deliverable based on vendor-specific objective evidence of selling price (“VSOE”), if available, or third-party evidence ("TPE") in the alternative if available, or finally our best estimate of selling price (“BESP”), if VSOE or TPE is not available. The Company begins to recognize revenue from license fees for its exchange (SAAS) and ASP products upon granting customer access to the respective processing platform. Transaction services fee revenue for this use of our exchanges or ASP platforms is recognized as the transactions occur and is generally billed in arrears. Revenues from RCS arrangements, which include data entry and call center services, and insurance certificate creation and tracking services, are recognized as the services are performed. Revenues from RCS consulting arrangements are recognized as the services are delivered on a time and materials basis. Service fees for hosting arrangements are recognized over the requisite service period. Revenue derived from the licensing of third party software products in connection with sales of the Company’s software licenses is recognized upon delivery together with the Company’s licensed software products. Fees for training, data conversion, installation, and consulting services fees are recognized as revenue when the services are performed. Revenues for maintenance and support services are recognized ratably over the term of the support agreement. Software development arrangements involving significant customization, modification or production are accounted for in accordance with the appropriate technical accounting guidance issued by the FASB using the percentage-of-completion method. The Company recognizes revenue using periodic reported actual hours worked as a percentage of total expected hours required to complete the project arrangement and applies the percentage to the total arrangement fee. Financial exchange revenue consists largely of transaction-based fees and fees from corporate and retail gift vouchers. The transaction-based fees are primarily based on a percentage of payment value processed for solutions such as retail and corporate payments, domestic money transfers, and general purpose reloadable cards. Transaction-based fees are recognized at the completion of the transaction. Gift voucher revenue is recognized at full purchase value at time of sale with the corresponding cost of vouchers recorded under direct expenses. Deferred revenue includes payments or billings that have been received or made prior to performance and, in certain cases, cash collections and primarily pertain to maintenance and support fees, initial setup or registration fees under hosting agreements, software license fees received in advance of delivery and acceptance, and software development fees paid in advance of completion and delivery.
Accounts Receivable and the Allowance for Doubtful Accounts Receivable	The unbilled receivables pertain to certain professional service engagements and system development projects for which the timing of billing is tied to contractual milestones . The Company is continuing to evaluate the 2017 acquisitions that collectively make up the EbixCash Financial Exchanges, refer to Part I, Item I Business, and their impact on our condensed consolidated balance sheets. The Company adheres to suc h contractually stated performance milestones and accordingly issues invoices to customers as per contract billing schedules. Accounts receivable are written off against the allowance for doubtful accounts receivable when the Company has exhausted all reasonable co llection efforts. Management specifically analyzes the aging of accounts receivable and historical bad debts, write-offs, customer concentrations, customer credit-worthiness, current economic trends, and changes in our customer payment patterns when evaluating the adequacy of the allowance for doubtful accounts receivable. Accounts Receivable and the Allowance for Doubtful Accounts Receivable —Reported accounts receivable as of December 31, 2017 include $94.5 million of trade receivables stated at invoice billed amounts and $23.3 million of unbilled receivables (net of a $4.1 million estimated allowance for doubtful accounts receivable). Reported accounts receivable at December 31, 2016 include $51.8 million of trade receivables stated at invoice billed amounts and $10.9 million of unbilled receivables (net of a $2.8 million estimated allowance for doubtful accounts receivable). The unbilled receivables pertain to certain professional service engagements and system development projects for which the timing of billing is tied to contractual milestones . The Company is continuing to evaluate the 2017 acquisitions that collectively make up the EbixCash Financial Exchanges, refer to Part I, Item I Business, and their impact on our condensed consolidated balance sheets. The Company adheres to suc h contractually stated performance milestones and accordingly issues invoices to customers as per contract billing schedules. Accounts receivable are written off against the allowance for doubtful accounts receivable when the Company has exhausted all reasonable co llection efforts. Management specifically analyzes the aging of accounts receivable and historical bad debts, write-offs, customer concentrations, customer credit-worthiness, current economic trends, and changes in our customer payment patterns when evaluating the adequacy of the allowance for doubtful accounts receivable. Bad debt expense was $1.7 million , $1.5 million , and $3.1 million for the year ended December 31, 2017 , 2016 , and 2015 , respectively.
Costs of Services Provided	Costs of Services Provided —Costs of services provided consist of data processing costs, customer support costs including personnel costs to maintain our proprietary databases, costs to provide customer call center support, hardware and software expense associated with transaction processing systems and exchanges, telecommunication and computer network expense, and occupancy costs associated with facilities where these functions are performed. Depreciation expense is not included in costs of services provided.
Capitalized Software Development Costs	Capitalized Software Development Costs —In accordance with the relevant FASB accounting guidance regarding the development of software to be sold, leased, or marketed, the Company expenses such costs as they are incurred until technological feasibility has been established, at and after which time those costs are capitalized until the product is available for general release to customers. Costs incurred to enhance our software products, after general market release of the services using the products, is expensed in the period they are incurred.
Goodwill and Indefinite-lived Intangible Assets	Goodwill and Indefinite-Lived Intangible Assets —Goodwill represents the cost in excess of the fair value of the identifiable net assets from the businesses that we acquire. In accordance with the relevant FASB accounting guidance, goodwill is tested for impairment at the reporting unit level on an annual basis or on an interim basis if an event occurred or circumstances change that would indicate that fair value of a reporting unit decreased below its carrying value. Potential impairment indicators include a significant change in the business climate, legal factors, operating performance indicators, competition, customer retention and the sale or disposition of a significant portion of the business. The Company applies the technical accounting guidance concerning goodwill impairment evaluation whereby the Company first assesses certain qualitative factors to determine whether the existence of events or circumstances would indicate that it is more likely than not that the fair value of any of our reporting units was less than its carrying amount. If after assessing the totality of events and circumstances, we were to determine that it is more likely than not that the fair value of a reporting unit is less than its carrying amount, then we would perform the two-step quantitative impairment testing described further below. The aforementioned two-step quantitative testing process involves comparing the reporting unit carrying values to their respective fair values; we determine fair value of our reporting units by applying the discounted cash flow method using the present value of future estimated net cash flows. If the fair value of a reporting unit exceeds its carrying value, then no further testing is required. However, if a reporting unit’s fair value were to be less than its carrying value, we would then determine the amount of the impairment charge, if any, which would be the amount that the carrying value of the reporting unit’s goodwill exceeded its implied value. We perform our annual goodwill impairment evaluation and testing as of September 30 each year. In 2017 the goodwill residing in the Broker Systems reporting unit, was evaluated for impairment based on an assessment of certain qualitative factors, and was determined not to have been impaired. In 2017 the goodwill residing in the Exchange reporting unit, the RCS reporting unit, and the Carrier reporting unit were evaluated for impairment using step-one of the quantitative testing process described above. The fair value of both of these reporting units were found to be greater than their carrying value, and thusly there was no need to proceed to step-two, as there was no impairment indicated. The Company’s indefinite-lived assets are associated with the estimated fair value of the contractual customer relationships existing with the property and casualty insurance carriers in Australia using our property and casualty ("P&C") data exchange and with certain large corporate customers using our client relationship management (“CRM”) platform in the United States. Prior to these underlying business acquisitions Ebix had pre-existing contractual relationships with these carriers and corporate clients. The contracts are renewable at little or no cost, and Ebix intends to continue to renew these contracts indefinitely and has the ability to do so. The proprietary technology supporting the P&C data exchange and CRM platform that is used to deliver services to these carriers and corporate clients, cannot feasibly be effectively replaced in the foreseeable future, and accordingly the cash flows forthcoming from these customers are expected to continue indefinitely. With respect to the determination of the indefinite life, the Company considered the expected use of these intangible assets, historical experience in renewing or extending similar arrangements, and the effects of competition, and concluded that there were no indications from these factors to suggest that the expected useful life of these customer relationships would be finite. The Company concluded that no legal, regulatory, contractual, or competitive factors limited the useful life of these intangible assets and therefore their life was considered to be indefinite, and accordingly the Company expects these customer relationships to remain the same for the foreseeable future. Additionally based on the final purchase price allocation valuation report of the EbixHealth JV, See Note 3 and 17 for further explanations, it was concluded that the value of the indefinite-lived intangibles identified as indefinite-lived customer relationships to be $11.2 million . The EbixHealth JV is a full-service third-party administrator (“TPA”) that specializes in the management, administration, and distribution of health benefit plans. Services include marketing support, underwriting, billing, claims processing, and cost containment such as utilization review and medical case management for fully-insured, self-funded and partially self-funded benefit plans, as well as international groups and individuals. As a TPA, the Company collects premiums from insureds and, after deducting its fees, remits these premiums to insurance companies. Unremitted insurance premiums and/or claim funds established for the benefit of various carriers are held in a fiduciary capacity until disbursed by the Company. The Company administers and collects the insurance premiums for the products of three affiliated insurance carriers which is part of the consolidated company IHC Health Holdings Corporation ("IHC") a 49% shareholder of the EbixHealth JV. The administrative agreements with the three affiliates accounted for approximately 83% of revenues for the year ended December 31, 2017. IHC is therefore considered a major customer of the EbixHealth JV and therefore considered indefinite-lived. The churn expected for indefinite-lived customers is assumed at 0% . The fair values of these indefinite-lived intangible assets were based on the analysis of discounted cash flow (“DCF”) models extended out fifteen years with a terminal value. In that indefinite-lived does not imply an infinite life, but rather means that the subject customer relationships are expected to extend beyond the foreseeable time horizon, we utilized fifteen year DCF projections with a terminal value, as the valuation models that were applied consider this time frame to be an indefinite period. Indefinite-lived intangible assets are not amortized, but rather are tested for impairment annually. We perform our annual impairment testing of indefinite-lived intangible assets as of September 30th of each year. During the years ended December 31, 2017 , 2016 and 2015 , we had no impairments to the recorded balances of our indefinite-lived intangible assets. We perform the impairment test for our indefinite-lived intangible assets by comparing the asset’s fair value to its carrying value. An impairment charge is recognized if the asset’s estimated fair value is less than its carrying value. Projections of cash flows are based on our views of revenue growth rates, operating costs, anticipated future economic conditions, the appropriate discount rates relative to risk, and estimates of residual values and terminal values. We believe that our estimates are consistent with assumptions that marketplace participants would use in their estimates of fair value. The use of different estimates or assumptions for our projected discounted cash flows (e.g., revenue growth rates, future economic conditions, discount rates, and estimates of terminal values) when determining the fair value of our reporting units could result in different values and may result in a goodwill impairment charge. As a practice, the Company closely monitors any reporting units that do not have a significantly higher fair value in excess of their carrying value.
Purchased Intangible Assets	Purchased Intangible Assets —Purchased intangible assets represent the estimated fair value of acquired intangible assets from the businesses that we acquire in the U.S. and foreign countries in which we operate. These purchased intangible assets include customer relationships, developed technology, informational databases, and trademarks. We amortize these intangible assets on a straight-line basis over their estimated useful lives, as follows: Life Category (yrs) Customer relationships 7-20 Developed technology 3-12 Dealer networks 15-20 Trademarks 3-15 Non-compete agreements 5 Database 10
Income Taxes	Income Taxes — The Company follows the asset and liability method of accounting for income taxes pursuant to the pertinent guidance issued by the FASB. Deferred income taxes are recorded to reflect the tax consequences on future years of differences between the tax basis of assets and liabilities, and operating loss and tax credit carry forwards, and their financial reporting amounts at each period end using enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled. In assessing the realizability of the deferred tax assets, management considers whether it is more likely than not that some portion or all of the deferred tax assets will not be realized. A valuation allowance is recorded, if necessary, for the portion of the deferred tax assets that are not expected to be realized based on the levels of historical taxable income and projections for future taxable income over the periods in which the temporary differences will be deductible. The Company follows the provisions of FASB accounting guidance on accounting for uncertain income tax positions. The guidance utilizes a two-step approach for evaluating tax positions. Recognition (“Step 1”) occurs when an enterprise concludes that a tax position, based solely on its technical merits is more likely than not to be sustained upon examination. Measurement (“Step 2”) is only addressed if Step 1 has been satisfied. Under Step 2, the tax benefit is measured at the largest amount of benefit, determined on a cumulative probability basis that is more likely than not to be realized upon final settlement. As used in this context, the term “more likely than not” is interpreted to mean that the likelihood of occurrence is greater than 50% .
Foreign Currency Translation	Foreign Currency Translation —The functional currency for the Company's main foreign subsidiaries in India, Singapore and Dubai is the U.S. dollar because the intellectual property research and development activities provided by its Singapore and Dubai subsidiaries, and the product development and information technology enabled services activities for the insurance industry provided by its India subsidiary, both in support of Ebix's operating divisions across the world, are transacted in U.S. dollars. The functional currency of the Company's other foreign subsidiaries is the local currency of the country in which the subsidiary operates. The assets and liabilities of these foreign subsidiaries are translated into U.S. dollars at the rates of exchange at the balance sheet dates. Income and expense accounts are translated at the average exchange rates in effect during the period. Gains and losses resulting from translation adjustments are included as a component of accumulated other comprehensive loss in the accompanying consolidated balance sheets. Foreign exchange transaction gains and losses that are derived from transactions denominated in a currency other than the subsidiary's functional currency are included in the determination of net income.
Advertising	Advertising —With the exception of certain direct-response costs in connection with our business services of providing medical continuing education to physicians, dentists and healthcare professionals, advertising costs are expensed as incurred. Advertising costs amounted to $6.1 million , $6.2 million , and $4.0 million in 2017 , 2016 and 2015 , respectively, and are included in sales and marketing expenses in the accompanying Consolidated Statements of Income. In 2017 and 2016 reported sales and marketing expenses included $3.9 million and $4.1 million , respectively, of amortization of certain direct-response advertising costs associated with our medical education services, which have been capitalized in accordance with Accounting Standards Codification ("ASC") Topic 340. These costs are being amortized to advertising expense over periods ranging from twelve to twenty-four months based on the type of product the customer purchased. Deferred advertising costs amounted to $1.9 million and $2.8 million at December 31, 2017 and 2016, respectively, and are included in other current assets and other assets on the consolidated balance sheet.
Sales Commissions	Sales Commissions —Certain sales commission paid with respect to subscription-based revenues are deferred and subsequently amortized into operating expenses ratably over the term of the related customer subscription contracts. As of December 31, 2017 and 2016 , $574 thousand and $612 thousand , respectively, of sales commissions were deferred and included in other current assets on the accompanying Consolidated Balance Sheets. During the years ended December 31, 2017 and 2016 the Company amortized $1.1 million and $1.3 million , respectively, of previously deferred sales commissions and included this expense in sales and marketing costs on the accompanying Consolidated Statements of Income.
Property and Equipment	Property and Equipment —Property and equipment is stated at cost less accumulated depreciation and amortization. Depreciation and amortization are computed using the straight-line method over the assets estimated useful lives. Leasehold improvements are amortized over the shorter of the expected life of the improvements or the remaining lease term. Repairs and maintenance are charged to expense as incurred and major improvements that extend the life of the asset are capitalized and depreciated over the expected remaining life of the related asset.

During 2017 India's revenue increased $47.7 million of which $5.3 million is due to the various new e-governance contracts with a number of large clients and $42.9 million due to its 2017 acquisitions of ItzCash, YouFirst, Wall Street, Paul Merchants, and Via. Latin America's revenues increased $12.9 million due primarily to the November 2016 acquisition of Wdev and a $1.4 million increase due to changes in foreign currency exchange rates. Australia's revenues increased by $3.2 million due to a combination of increased professional services and transaction fees, and a $1.1 million increase due to changes in foreign currency exchange rates. Canada's revenues increased by $1.2 million due primarily to increased professional services. Increases in Singapore, Indonesia, Philippines and United Arab Emirates are due to the November 2017 acquisition of Via. During 2016 the change in foreign currency exchange rates decreased reported Australian and Latin America operating revenues by $(410) thousand and $(300) thousand , respectively. India's 2016 operating revenues increased $10.6 million or 300% due primarily to the various new e-governance contracts with a number of large clients. Europe's revenues increased $8.8 million , net of $(2.2) million decrease due to changes in foreign currency exchange rates, due primarily to the execution and commencement of certain significant contracts.

The Europe increase of $3.9 million is primarily due to a 9.3% strengthening of the British Pound Sterling versus the U.S. Dollar which caused a $2.0 million increase in the translation of long-lived assets, an increase in deferred tax assets of $3.2 million due to the release of valuation allowances of operating loss carryforwards, partially offset by the amortization of intangible assets and capitalized software development costs. In the geographical information table above the significant changes to long-lived assets from December 31, 2015 to December 31, 2016 are explained as follows: the U.S. increase of $11.3 million is primarily comprised of a $14.6 million net increase due to the consolidation of the EbixHealth JV commensurate with the step up in ownership to 51% , partially offset by a $(4.7) million decrease of intangibles due to amortization; the Latin America increase of $17.7 million is due to the Wdev acquisition (for which the valuation and purchase accounting is preliminary); the Singapore decrease of $51.4 million and the Dubai increase of $54.2 million are due to the transfer of certain intangible assets between these locations (net of deferred taxes); the India increase of $8.4 million is primarily due an increase in deferred tax assets of $4.8 million associated with the payments and accruals of Minimum Alternative Tax, and $3.5 million of fixed assets additions associated with the continued build out of our product development facilities, and the growth of the Ebix-Vayam JV; the Europe decrease of $6.3 million is primarily due to a 16.6% weakening of British Pound Sterling versus the U.S. Dollar which caused a $4.3 million decrease in the translation of long-lived assets, partially offset by the amortization of intangible assets and capitalized software development costs.
