	2	Summary of significant accounting policies
	Basis of presentation
	The accompanying unaudited interim condensed consolidated financial statements are prepared in conformity with accounting principles generally accepted in the United States of America (U.S. GAAP) and include the accounts of the Company and its wholly-owned subsidiaries. Ownership interests of minority interests are recorded as noncontrolling interest. These interim condensed consolidated financial statements are stated in U.S. dollars. Intercompany transactions and balances have been eliminated for consolidation purposes.
	Substantially all net revenues, cost of net revenues and operating expenses, are generated in the Company’s foreign operations, amounting to approximately 99.7% and 99.6% of the consolidated amounts during the nine-month periods ended September 30, 2014 and 2013. Long-lived assets and Goodwill located in the foreign operations totaled $162,744,933 and $183,922,432 as of September 30, 2014 and December 31, 2013, respectively.

	These interim condensed consolidated financial statements reflect the Company’s consolidated financial position as of September 30, 2014 and December 31, 2013. These financial statements also show the Company’s consolidated statements of income, of comprehensive income for the nine-month and three-month periods ended September 30, 2014 and 2013, and statement of cash flows for the nine-month periods ended September 30, 2014 and 2013. These interim condensed consolidated financial statements include all normal recurring adjustments that management believes are necessary to fairly state the Company’s financial position, operating results and cash flows.
	Because all of the disclosures required by U.S. GAAP for annual consolidated financial statements are not included herein, these unaudited interim condensed financial statements should be read in conjunction with the audited consolidated financial statements and the notes thereto for the year ended December 31, 2013, contained in the Company’s Annual Report on Form 10-K filed with the Securities and Exchange Commission (“SEC”). The condensed consolidated statements of income, of comprehensive income and of cash flows for the periods presented herein are not necessarily indicative of results expected for any future period.
	Foreign currency translation
	Venezuelan currency status
	All of the Company’s foreign operations have determined the local currency to be their functional currency, except for Venezuela since January 1, 2010, as described below. Accordingly, these foreign subsidiaries translate assets and liabilities from their local currencies into U.S. dollars by using the period-end exchange rates while income and expense accounts are translated at the average rates in effect during the period, unless exchange rates fluctuate significantly during the period, in which case the exchange rates at the date of the transaction are used. The resulting translation adjustment is recorded as a component of other comprehensive income (loss). Gains and losses resulting from transactions denominated in non-functional currencies are recognized in earnings.
	According to U.S. GAAP, the Company has transitioned its Venezuelan operations to highly inflationary status as from January 1, 2010, which requires that transactions and balances are re-measured as if the U.S. dollar were the functional currency for such operation.
	On February 9, 2013, the Venezuelan Central Bank (“BCV”) eliminated the SITME and devalued the official exchange rate used to re-measure our Venezuelan subsidiaries’ non-U.S. dollar denominated monetary assets and liabilities as from February 9, 2013 to 6.3 BsF (Bolivares Fuertes) per U.S. dollar. The effect of using the devalued official rate of 6.3 BsF per U.S. dollar generated a foreign currency loss that amounted to $6.4 million in the first quarter of 2013.
	On March 19, 2013, the BCV announced the creation of the Sistema Complementario de Administración de Divisas (SICAD 1), which acts jointly with the Commission for the Administration of Foreign Exchange Control (CADIVI). In order to operate within this system, a company should be registered at the Registro Automatizado (Automatized Register, or RUSAD). The acquisition of foreign currencies under this system is organized under an auction process to obtain foreign currencies for payments to foreign suppliers, where the minimum exchange rate to be offered is 6.3 BsF per U.S. dollar.
	During December 2013, the Venezuelan regulation that created the SICAD 1 was amended to expand its use, and to require publication of the average exchange rate implied by transactions settled in SICAD 1 auctions. Additionally, on January 23, 2014, the exchange regulation was amended to include foreign currency sales for certain transactions, such as but not limited to: contracts for leasing and services, use and exploitation of patents, trademarks, foreign investments and payments of royalties, contracts for technology import and technical assistance. Due to the change in rules that provided for the creation of the SICAD 1 system, the official exchange rate remains only available to obtain foreign currency to pay for a limited list of goods considered to be of high priority by the Government, which does not include those relating to the Company’s business. As a consequence, SICAD 1 became, from that moment, the primary system to which the Company would have to request U.S. dollars to settle its transactions. As a result, from January 24 to May 15, 2014, the exchange rate used to re-measure the Company’s net monetary asset position in BsF and BsF transactions of its Venezuelan operations was the SICAD 1 exchange rate.
	In late February 2014, the Venezuelan government issued a decree to open a new exchange control mechanism (“SICAD 2”) that should allow the purchase of foreign exchange currencies, through authorized foreign exchange operators offered by individuals and companies such as Petróleos de Venezuela, S.A. (PDVSA, the oil state-owned corporation of Venezuela), the BCV and other public entities authorized by the Ministry of Finance. The Venezuelan government has published operating rules for the new exchange mechanism in Exchange Agreement N° 27, and SICAD 2 began operating on March 24, 2014. Since implementation of the SICAD 1 system, the Company was unsuccessful in gaining access to U.S. dollars through SICAD 1. As a result of this ongoing lack of access to the SICAD 1 auction system, on May 16, 2014, the Company decided to start requesting U.S. dollars through the SICAD 2 mechanism. The SICAD 2 system is an open mechanism that permits any company to request dollars for any purpose. Consequently, the Company is eligible for and has been granted, U.S. dollars through the SICAD 2 mechanism.
	As a consequence of the determination to obtain U.S. dollars through SICAD 2 and the lack of access to SICAD 1 since May 16, 2014, the Company concluded that the SICAD 2 exchange rate should be used to re-measure their bolivar-denominated monetary assets and liabilities in BsF and to re-measure the results of its Venezuelan operations, effective as of May 16, 2014. As a consequence, the Company has recorded a foreign exchange loss of $16.5 million during the second quarter of 2014. As of September 30, 2014 the SICAD 2 exchange rate was 49.99 BsF per U.S. dollar.

	In light of the current economic conditions in Venezuela, and the determination to access SICAD 2 and re-measure the BsF denominated monetary assets and liabilities of its Venezuelan subsidiaries, and the lower U.S. dollar-equivalent cash flows now expected from the Venezuelan business, the Company reviewed the long-lived assets, goodwill and intangible assets with indefinite useful life for impairment, including considering the current expected use of these assets in light of this foregoing. The Company owns two office spaces in Venezuela that had expected to use to support the main operating activities in that country. However, due to the current conditions, the Company now intends to rent these office spaces to third parties to generate rental income and will consider opportunities for disposal of these assets if real estate market conditions are favorable. Because the Company has concluded that the carrying value of these two real estate properties will not be recoverable, it has recorded an impairment of long-lived assets of $49,495,686 during May 2014. The carrying amount has been adjusted to its estimated fair value of approximately $22 million.
	Until 2010 the Company was able to obtain U.S. dollars for any purpose, including dividends distribution, using alternative mechanisms other than through the CADIVI. Those U.S. dollars, obtained at a higher exchange rate than the one offered by CADIVI, and held in balance at U.S. bank accounts of our Venezuelan subsidiaries, were used for dividend distributions from our Venezuelan subsidiaries. Our Venezuelan subsidiaries have not requested authorization since 2012 to acquire U.S. dollars to make dividend distributions. The Company has not distributed dividends from our Venezuelan subsidiaries since 2011.
	The following table sets forth the assets, liabilities and net assets of the Company’s Venezuelan subsidiaries, before intercompany eliminations, as of September 30, 2014 and December 31, 2013 and net revenues for the nine-month periods ended September 30, 2014 and 2013:


			Nine-month periods ended September 30,
			2014				2013
	Venezuelan operations
	Net Revenues		$	45,184,278			$	55,695,385


			September 30,				December 31,
			2014				2013
	Assets			65,444,729				126,873,804
	Liabilities			(38,504,273	)			(62,437,338	)

	Net Assets		$	26,940,456			$	64,436,466

	As of September 30, 2014, net assets (before intercompany eliminations) of the Venezuelan subsidiaries amounted to approximately 7.9% of consolidated net assets, and cash and investments of the Venezuelan subsidiaries held in local currency in Venezuela amounted to approximately 2.3% of our consolidated cash and investments.

	The Company’s ability to obtain U.S. dollars in Venezuela is negatively affected by the exchange regulations in Venezuela that are described above and elsewhere in these financial statements. In addition, its business and ability to obtain U.S. dollars in Venezuela would be negatively affected by additional material devaluations or the imposition of significant additional and more stringent controls on foreign currency exchange by the Venezuelan government.
	Despite the current difficult macroeconomic environment in Venezuela, the Company continues to actively manage, through its Venezuelan subsidiaries, its investment in Venezuela. Regardless the current operating, political and economic conditions and certain other factors in Venezuela, management currently plans to continue supporting its business in Venezuela in the long run.
	Argentine currency status
	The Argentine government has implemented certain measures that control and restrict the ability of companies and individuals to exchange Argentine pesos for foreign currencies. Those measures include, among other things, the requirement to obtain the prior approval from the Argentine Tax Authority of the foreign currency transaction (for example and without limitation, for the payment of non-Argentine goods and services, payment of principal and interest on non-Argentine debt and also payment of dividends to parties outside of the country), which approval process could delay, and eventually restrict, the ability to exchange Argentine pesos for other currencies, such as U.S. dollars. Those approvals are administered by the Argentine Central Bank through the Local Exchange Market (“Mercado Unico Libre de Cambios”, or “MULC”), which is the only market where exchange transactions may be lawfully made.
	Further, restrictions also currently apply to the acquisition of any foreign currency for holding as cash within Argentina. Although the controls and restrictions on the acquisition of foreign currencies in Argentina place certain limitations on our current ability to convert cash generated by our Argentine subsidiaries into foreign currencies, based on the current state of Argentine currency rules and regulations, we do not expect that the current controls and restrictions, will have a material adverse effect on our business plans in Argentina or on our overall business, financial condition or results of operations.
	Additionally, during January 2014 the Argentinean peso exchange rate against the U.S. dollar increased in approximately 23%, from 6.52 Argentinean Pesos per U.S. dollar as of December 31, 2013 to approximately 8.0 Argentinean Pesos per U.S. dollar. Due to the abovementioned devaluation, during the first quarter of 2014, the reported net assets in Argentina decreased in $14,625,451 with the related impact in Other Comprehensive Income and the Company recognized a foreign exchange gain of $4,597,510. As of September 30, 2014, the Argentinean Peso exchange rate was $8.43 per U.S. dollar.

	Income Tax Holiday in Argentina
	According to Argentine law, from fiscal year 2008, the Company’s Argentine subsidiary has been a beneficiary of a software development law. Part of the benefits obtained from being a beneficiary of the aforementioned law is a relief of 60% of total income tax determined in each year, thus resulting in an effective tax rate in Argentina lower than the income tax law statutory rate. The law expired on September 17, 2014. As a consequence, the average tax rate for 2014 would be approximately 22% as we expect no income tax holiday during last quarter of fiscal year 2014.
	Aggregate tax benefit totaled $2,044,806 and $2,973,762 for the three-month periods ended September 30, 2014 and 2013, respectively, while for the nine-month periods ended at such dates amounted to $5,643,975 and $7,742,787, respectively. Aggregate per share effect of the Argentine tax holiday amounted to $0.05 and $0.07 for the three-month periods ended September 30, 2014 and 2013, respectively, while for the nine-month periods ended at such dates amounted to $0.13 and $0.18, respectively.
	In addition, during fiscal year 2013 the Company acquired a software development company (see Note 4), located in the Province of Cordoba, Argentina, which is also beneficiary of the aforementioned income tax holiday, however the total benefit obtained is immaterial.
	If the Company had not been granted the Argentine tax holiday, it would have pursued an alternative tax planning strategy and, therefore, the impact of not having this particular benefit would not necessarily be the abovementioned dollar and per share effect.
	On August 17, 2011, the Argentine government issued a new software development law and on September 9, 2013 the regulatory decree was issued, which established the new requirement to become beneficiary of the new software development law. The new decree establishes compliance requirements with annual incremental ratios related to exports of services and research and development expenses that must be achieved to remain within the tax holiday. The Argentine operation will have to achieve certain required ratios annually under the new software development law.
	If we are successful in being admitted as beneficiaries under the new law, the current income tax relief would decrease, but it is currently estimated that the Argentine effective income tax rate would still be materially lower than the statutory income tax rate. Also, the tax holiday under the new law would last until 2019.
	The Industry Secretary resolution which rules, among other provisions, on the mechanism to file the information to obtain the benefits derived from the new software development law was issued in late February 2014. During May 2014, the Company presented all the required documentation in order to apply for the new software development law. At the date of issuance of these interim condensed consolidated financial statements, the Industry Secretary resolution which approves the Company’s application is still pending.

	The following table sets forth the Company’s accumulated other comprehensive income as of September 30, 2014 and the year ended December 31, 2013:

Impairment of long-lived assets
The Company reviews its long-lived assets for impairment whenever events or changes in circumstances indicate that the carrying value of an asset may not be recoverable.

As explained in the section “Foreign Currency Translation” of the present Note to these interim condensed consolidated financial statements, as a consequence of an ongoing lack of access to SICAD 1 auction system, on May 16, 2014 the Company decided to start requesting U.S. dollars through the SICAD 2 mechanism and use the SICAD 2 exchange rate to re-measure its Bolivar-denominated monetary assets and liabilities in BsF and to re-measure the result of its Venezuelan operations, effective as of May 16, 2014.
Considering this change in facts and circumstances and the lower U.S. dollar-equivalent cash flows now expected from our Venezuelan business, and their expected current use in the new context (receive rental income instead of using the long-lived assets to support the Company’s future growth of operations in Venezuela), the Company compared the carrying amount of the long-lived assets with the expected undiscounted future net cash flows and concluded that two office spaces held in Caracas, Venezuela, should be impaired. As a consequence, the Company estimated the fair value of the impaired long-lived assets and recorded an impairment loss of $49,495,686 during the second quarter of 2014.
Convertible Senior Notes
On June 30, 2014, the Company issued $330 million of 2.25% convertible senior notes due 2019 (the “Notes”). The Notes are unsecured, unsubordinated obligations of the Company, which pay interest in cash semi-annually, on January 1 and July 1, at a rate of 2.25% per annum. The Notes will mature on July 1, 2019 unless earlier repurchased or converted in accordance with their terms prior to such date. The Notes may be converted, under specific conditions, based on an initial conversion rate of 7.9353 shares of common stock per $1,000 principal amount of Notes (equivalent to an initial conversion price of approximately $126.02 per share of common stock), subject to adjustment as described in the indenture governing the Notes.
Prior to January 1, 2019, the Notes will be convertible only upon the occurrence of certain events and during certain periods, and thereafter, at any time until the close of business on the second scheduled trading day immediately preceding the maturity date of the Notes. The conversion rate is subject to customary anti-dilution adjustments. Following certain corporate events described in the Indenture that occur prior to the maturity date, the conversion rate will be increased for a holder who elects to convert its Notes in connection with such corporate event in certain circumstances. The Indenture contains customary terms and covenants, including that upon certain events of default occurring and continuing, either the Trustee or the holders of at least 25% in principal amount of the outstanding Notes may declare 100% of the principal of, and accrued and unpaid interest on, all the Notes to be due and payable.
In accordance with ASC 470-20 Debt with Conversion and Other Options, the convertible debt instrument within the scope of the cash conversion subsection, was separated into debt and equity components at issuance and a fair value was assigned. The value assigned to the debt component was the estimated fair value, as of the issuance date, of a similar debt without the conversion feature. As of the issuance date, the Company determined the fair value of the liability component of the Notes based on market data that was available for senior, unsecured nonconvertible corporate bonds issued by comparable companies. The difference between the cash proceeds and this estimated fair value, represents the value assigned to the equity component and was recorded as a debt discount. The debt discount is amortized using the effective interest method from the origination date through its stated contractual maturity date.
The initial debt component of the Notes was valued at $283,015,125, based on the contractual cash flows discounted at an appropriate market rate for a non-convertible debt at the date of issuance, which was determined to be 5.55%. The carrying value of the permanent equity component reported in additional paid-in-capital was initially valued at $46,984,875. The effective interest rate after allocation of transaction costs to the liability component is 6.10% and is used to amortize the debt discount and transaction costs.
In connection with the issuance of the Notes, the Company paid approximately $19,668,000 to enter into capped call transactions with respect to its common shares (the “Capped Call Transactions”), with certain financial institutions. The Capped Call Transactions are expected generally to reduce the potential dilution upon conversion of the Convertible Notes and / or offset any cash payments the Company may be required to make in excess of the principal amount of any converted notes in the event that the market price of the common shares is greater than the strike price of the Capped Call Transactions, initially set at $126.02 per common share, which corresponds to the initial conversion price of the Notes and is subject to anti-dilution adjustments substantially similar to those applicable to the conversion rate of the Notes, and have a cap price of approximately $155.81 per common share.
The $19,668,000 cost of the capped call transactions, which net of deferred income tax effect amounts to $12,784,200, is included as a net reduction to additional paid-in capital in the stockholders’ equity section of our consolidated balance sheets.
For more detailed information in relation to the Notes and the Capped Call transactions, see Note 9 to these interim condensed consolidated financial statements.
Use of estimates
The preparation of interim condensed consolidated financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Estimates are used for, but not limited to accounting for allowance for doubtful accounts and chargeback provisions, depreciation, amortization, recoverability of goodwill and intangible assets with indefinite useful life, useful life of long-lived assets, impairment of short-term and long-term investments, impairment of long-lived assets, compensation costs, relating to the Company’s long term retention plan, fair value of convertible debt note, recognition of income taxes and contingencies. Actual results could differ from those estimates.

Recently issued accounting pronouncements
In April 2014, the FASB issued the Accounting Standards Update (“ASU”) N° 2014-8, “Reporting Discontinued Operations and Disclosures of Disposals of Components of an Entity”, which changes the criteria for determining which disposals can be presented as discontinued operations and modifies related disclosure requirements. Under the ASU, only disposals that represent a strategic shift that has (or will have) a major effect on the entity’s results and operations would qualify as discontinued operations. In addition, the ASU (1) expands the disclosure requirements for disposals that meet the definition of s discontinued operation, (2) requires entities to disclose information about disposals of individually significant components, and (3) defines “discontinued operations” similarly to how it is defined under IFRS 5, “Non-current Assets Held for Sale and Discontinued Operations”. The standard is required to be adopted in annual periods beginning on or after December 15, 2014, and interim periods within those annual periods. Early adoption is permitted, but only for disposals (or classifications as held for sale) that have not been reported in financial statements previously issued or available for issuance. The Company does not anticipate that this adoption will have a significant impact on its financial position, results of operations or cash flows.
On May 28, 2014, the FASB issued the Accounting Standard Update (“ASU”) N° 2014-09, “Revenue contracts with clients”, which changes in the timing of revenue recognition, includes variable consideration in the transaction price prior to resolution of contingencies, allocates the transaction price based on standalone selling price, among other changes. This standard is required to be adopted for annual reporting periods beginning after December 15, 2016 for public entities, no early adoption is permitted. The Company is assessing the effects that the adoption of this accounting pronouncement will have on the Company’s financial position, results of operations or cash flows.
In August 2014, the FASB issued new guidance related to the disclosures around going concern. The new standard provides guidance around management’s responsibility to evaluate whether there is substantial doubt about an entity’s ability to continue as a going concern and to provide related footnote disclosures. The new standard is effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2016. Early adoption is permitted. The adoption of this standard is not expected to have a material impact the Company’s financial statements.

	Basic earnings per share for the Company’s common stock is computed by dividing, net income available to common shareholders attributable to common stock for the period, and the corresponding adjustment attributable to changes in redeemable non-controlling interest, by the weighted average number of common shares outstanding during the period.
	Diluted earnings per share for the Company’s common stock assume the issuance of shares as a consequence of a convertible debt securities conversion event.
	The following table shows how net income is allocated using the “if converted” method for earnings per common share for the three and nine-month periods ended September 30, 2014 and 2013:

	On June 30, 2014, the Company issued the 2.25% Convertible Senior Notes due 2019 (please refer to Note 9 of these interim condensed consolidated financial statements for discussion regarding these debt notes). The conversion of these debt notes are considered for diluted earnings per share utilizing the “if converted” method, the effect of that conversion is not assumed for purposes of computing diluted earnings per share if the effect is antidilutive. For the three and nine-month periods ended September 30, 2014, the effect of the Convertible Senior Notes due 2019 on diluted earnings per share was anti-dilutive and, as a consequence, it was not computed for diluted earnings per share.
	The denominator for diluted net income per share for the three and nine-month periods ended September 30, 2014 does not include any effect from the capped call because it would be antidilutive. In the event of conversion of any or all of the Notes, the shares that would be delivered to the Company under the note hedges are designed to partially neutralize the dilutive effect of the shares that the Company would issue under the Notes.

	The aggregate purchase price for the acquisition of the 100% of the acquired business was $37,989,865, measured at its fair value, amount that included: (i) the total cash payment of $32,147,755 at closing day; (ii) an escrow of $1,000,000 held in an escrow agent, according to the stock purchase agreement; (iii) the contingent additional cash considerations and escrows up to $4,621,085 in case the companies achieve certain revenue performance targets during 2014 and 2015, measured at fair value; and, (iv) an additional price adjustment escrow of $221,025.
	In addition, the Company incurred in certain direct costs of the business combination which were expensed as incurred.
	The Company’s condensed consolidated statement of income includes the results of operations of the acquired business as from April 8, 2014. The net revenues and net income of the acquiree included in the Company’s interim condensed consolidated statement of income since the acquisition amounted to $6,882,072 and $1,217,431, respectively.
	The following table summarizes the preliminary purchase price allocation for the acquisition:

	The purchase price was allocated based on the provisional measurement of the fair value of assets acquired and liabilities assumed considering the information available as of the date of these unaudited interim condensed consolidated financial statements. The valuation of identifiable intangible assets acquired reflects management’s estimates based on the use of established valuation methods. Such assets consist of trademarks, customer lists, software and non-solicitation agreements for a total amount of $19,036,493. Management of the Company estimates that trademarks have an indefinite lifetime and the intangible assets associated with customer list will be amortized over a ten year period. The non-solicitation agreement intangible asset will be amortized over a four year period and the software in three years.
	The Company recognized goodwill for this acquisition based on management expectation that the acquired business will improve the Company’s business.
	Tax goodwill related to the proportion acquired by Meli Inversiones SpA (Chile) is deductible for tax purposes.
	The results of operations for periods prior to the acquisition for each acquisition, both individually and in the aggregate, were not material to the interim condensed consolidated statements of income of the Company and, accordingly, supplemental pro-forma information has not been presented.
	Acquisition of Software Development Company in Argentina
	On March 22, 2013, the Company completed, through its subsidiaries Meli Participaciones S.L. (ETVE) and MercadoLibre S.R.L. (MercadoLibre Argentina) (together referred to as the “Buyer”), the acquisition of the 100% of equity interest in a software development company located and organized under the laws of the Province of Cordoba, Argentina. The objective of the acquisition was to enhance the capabilities of the Company in terms of software development.
	The aggregate purchase price for the acquisition of the 100% of the acquired business was $3,454,497 (settled in Argentine pesos 17,652,480). On such same date, the Buyer paid and agreed to pay the purchase price as follows: i) $2,191,781 in cash; ii) set an escrow amounting to $489,237 for a 24-months period, aiming to cover unexpected liabilities and negative working capital; iii) set an escrow amounting to $547,945 for a 36-months period, aiming to continue the employment relationship of certain key employees; and iv) on June 24, 2013 the Company paid the remaining $225,534 net of certain negative working capital adjustments.
	In addition, the Company incurred in certain direct costs of the business combination which were expensed as incurred.
	The above mentioned escrow for the continuing employment relationship of $547,945 is expensed over the 36-months period or a lesser period of time if certain other conditions determined in the Selling and Purchase Agreement (SPA) occur. The escrow will be released at the end of such period, together with the accrued interest.

	The Company’s interim condensed consolidated statement of income includes the results of operations of the acquired business as from March 22, 2013. The net revenues and net loss of the acquiree included in the Company’s consolidated statement of income as of December 31, 2013 since the acquisition amounted to $524,965 and $7,562, respectively.

	Purchase price			2,906,552
	Escrow for employment relationship			547,945

	Aggregate price paid		$	3,454,497

	Supplemental pro-forma information required by U.S. GAAP, is impracticable after making every reasonable effort to do so, however, amounts involved are deemed to be immaterial.
	Arising goodwill has been allocated proportionally to each of the segments identified by the Company’s management, considering the synergies expected from this acquisition and it is expected that the acquiree will contribute to the earnings generation process of such segments.
	The Company recognized goodwill for this acquisition based on management expectation that the acquired businesses will expand and improve the Company’s business.
	Goodwill is not deductible for tax purposes.

Segment Reporting	'
	5	Segment reporting
	Reporting segments are based upon the Company’s internal organizational structure, the manner in which the Company’s operations are managed, the criteria used by management to evaluate the Company’s performance, the availability of separate financial information, and overall materiality considerations.
	Segment reporting is based on geography as the main basis of segment breakdown to reflect the evaluation of the Company’s performance defined by the management. The Company’s segments include Brazil, Argentina, Mexico, Venezuela and other countries (such as Chile, Colombia, Costa Rica, Dominican Republic, Ecuador, Panama, Peru, Portugal, Uruguay and USA).

	Direct contribution consists of net revenues from external customers less direct costs and any impairment of long lived assets. Direct costs include specific costs of net revenues, sales and marketing expenses, and general and administrative expenses over which segment managers have direct discretionary control, such as advertising and marketing programs, customer support expenses, allowances for doubtful accounts, payroll, third party fees. All corporate related costs have been excluded from the Company’s direct contribution.
	Expenses over which segment managers do not currently have discretionary control, such as certain technology and general and administrative costs are monitored by management through shared cost centers and are not evaluated in the measurement of segment performance.
	The following tables summarize the financial performance of the Company’s reporting segments:

	As of September 30, 2014, the Company’s financial assets valued at fair value consisted of assets valued using i) Level 1 inputs: unadjusted quoted prices in active markets (Level 1 instrument valuations are obtained from observable inputs that reflect quoted prices (unadjusted) for identical assets in active markets); and ii) Level 2 inputs, which are obtained from readily-available pricing sources for comparable instruments as well as instruments with inactive markets at the measurement date. As of September 30, 2014, the Company did not have any assets without market values that would require a high level of judgment to determine fair value (Level 3).
	The unrealized net gains or loss on short term and long term investments are reported as a component of other comprehensive income. The Company does not anticipate any significant realized losses associated with those investments in excess of the Company’s historical cost.
	In addition, as of September 30, 2014 and December 31, 2013, the Company had $73,847,387 and $66,677,156 of short-term investments, respectively, which consisted of time deposits. Those investments are accounted for at amortized cost which, as of September 30, 2014 and December 31, 2013, approximates their fair values.
	As of September 30, 2014 and December 31, 2013, the carrying value of the Company’s financial assets and liabilities measured at amortized cost approximated their fair value mainly because of its short term maturity. These assets and liabilities included cash and cash equivalents (excluding money markets funds), accounts receivables, credit card receivables, funds payable to customers, other receivables, other assets, accounts payables, social security payables, taxes payables, provisions and other liabilities. The convertible senior notes approximate their fair value as explained in Note 9 to these interim condensed consolidated financial statements. The rest of the loans payable and other financial liabilities approximate their fair value because the interest rate of the loans, are not materially different from market interest rate for similar instruments.

	The following table summarizes the fair value level for those financial assets and liabilities of the Company measured at amortized cost as of September 30, 2014 and December 31, 2013:

	Litigation and Other Legal Matters
	The Company is subject to certain contingent liabilities with respect to existing or potential claims, lawsuits and other proceedings. The Company accrues liabilities when it considers probable that future costs will be incurred and such costs can be reasonably estimated. The proceeding-related reserve is based on developments to date and historical information related to actions filed against the Company. As of September 30, 2014, the Company had established reserves for proceeding-related contingencies of $4,056,174 to cover legal actions against the Company in which its Management has assessed the likelihood of a final adverse outcome as probable. In addition, as of September 30, 2014 the Company and its subsidiaries are subject to certain legal actions considered by the Company’s management and its legal counsels to be reasonably possible for an aggregate amount up to $4,435,042.
	No loss amount has been accrued for such reasonably possible legal actions of which most significant (individually or in the aggregate) are described below.
	As of September 30, 2014, there were 36 lawsuits pending against our Argentine subsidiary in the Argentine ordinary courts and 638 pending claims in the Argentine Consumer Protection Agencies, where a lawyer is not required to file or pursue a claim.
	As of September 30, 2014, there were 90 claims pending against our Mexican subsidiary in the Mexican Consumer Protection Agencies.
	As of September 30, 2014, 662 legal actions were pending in the Brazilian ordinary courts. In addition, as of September 30, 2014, there were 2,922 cases still pending in Brazilian consumer courts. Filing and pursuing of an action before Brazilian consumer courts do not require the assistance of a lawyer. In most of the cases filed against the Company, the plaintiffs asserted that the Company was responsible for fraud committed against them, or responsible for damages suffered when purchasing an item on the Company’s website, when using MercadoPago, or when the Company invoiced them.
	On March 17, 2006, Vintage Denim Ltda., or Vintage, sued the Company’s Brazilian subsidiaries MercadoLivre.com Atividades de Internet Ltda. and eBazar.com.br Ltda. in the 29th Civil Court of the County of São Paulo, State of São Paulo, Brazil. Vintage requested a preliminary injunction alleging that these subsidiaries were infringing Diesel trademarks and

	their right of exclusive distribution as a result of sellers listing allegedly counterfeit and original imported Diesel branded clothing through the Brazilian page of the Company’s website, based on Brazilian Industrial Property Law (Law 9,279/96). Vintage sought an order enjoining the sale of Diesel-branded clothing on the Company’s platform. A preliminary injunction was granted on April 11, 2006 to prohibit the offer of Diesel-branded products, and a fine for non-compliance was imposed in the approximate amount of $5,300 per defendant per day of non-compliance. The Company appealed that fine and obtained its suspension in 2006. Because the appeal of the preliminary injunction failed, in March of 2007, Vintage presented petitions alleging the Company’s non-compliance with the preliminary injunction granted to Vintage and requested a fine of approximately $3.5 million against the Company’s subsidiaries, which represents approximately $5,300 per defendant per day of alleged non-compliance since April 2006. In July 2007, the judge ordered the payment of the fine mandated in the preliminary injunction, without specifying the amount. In September 2007, the judge decided that (i) the Brazilian subsidiaries were not responsible for alleged infringement of intellectual property rights by its users; and that (ii) the plaintiffs did not prove the alleged infringement of its intellectual property rights. However, the decision maintained the injunction until such ruling is non-appealable. The plaintiff appealed the judge’s ruling regarding the subsidiary’s non-responsibility and the Company appealed the decision that maintained the preliminary injunction. On July 26, 2011 the State Court of Appeals of the State of São Paulo confirmed the judge’s ruling regarding our subsidiary’s non-responsibility. Vintage appealed the decision of the State Court of Appeals of the State of São Paulo to the Brazilian Federal Superior Court of Justice. On July 3, 2014, Vintage appeal was denied by the Brazilian Federal Superior Court of Justice. On August 12, 2014, Vintage presented an interlocutory appeal to the Brazilian Federal Superior Court of Justice, seeking the Court to review its previous decision. On September 30, 2014 the Brazilian Federal Superior Court of Justice overruled Vintage’s appeal and Vintage did not appeal the decision, therefore the favorable ruling is confirmed. The case should be closed in the following days.
	On August 25, 2010, Citizen Watch do Brasil S/A, or Citizen, sued Brazilian subsidiaries in the 31th Central Civil Court State of São Paulo, Brazil. Citizen alleged that the Brazilian subsidiaries were infringing Citizen’s trademarks as a result of users selling allegedly counterfeit Citizen watches through the Brazilian page of the Brazilian subsidiaries’ website. Citizen sought an order enjoining the sale of Citizen-branded watches on the Brazilian subsidiaries’ Marketplace with a $6,000 daily non-compliance penalty. On September 23, 2010, the Brazilian subsidiaries were summoned of an injunction granted to prohibit the offer of Citizen products on its platform, but the penalty was established at $6,000 per day. On September 26, 2010, the Brazilian subsidiaries presented their defense and appealed the decision of the injunction relief to the State Court of Appeals of São Paulo on September 27, 2010. On October 22, 2010 the injunction granted to Citizen was suspended. On March 23, 2011, the Company’s appeal regarding the injunction granted to Citizen was ruled in favor of the Brazilian subsidiaries. On May 4, 2011, Citizen presented a motion to clarify the decision but it was dismissed on March 14, 2012. On May 28, 2012, the Plaintiff filed a special recourse related to the injunction relief to the State Court of Appeals, and the

	Brazilian subsidiaries presented their defense on August 16, 2012 which was not admitted. In September 2012, the Plaintiff filed a legal action against the Brazilian subsidiaries with same arguments alleged in the injunction request and seeking for compensatory and statutory damages and defenses were presented on March 20, 2013. On January 9, 2013, Citizen presented a motion to request the appeal to be ruled by the Brazilian Superior Court of Justice (Superior Tribunal de Justiça). On March 1, 2013, the Company presented its response to that appeal. On August 27, 2013, the Brazilian Superior Court of Justice ruled against Citizen’s appeal. The Superior Court of Justice ruled that the Brazilian subsidiaries were not responsible for alleged infringement of intellectual property rights by its users and that they should comply with the “notice and take down” procedure it already have in place. On October 4, 2013, Citizen presented a motion to clarify mentioned decision issued by the Brazilian Superior Court of Justice and such motion was denied on November 11, 2013. Citizen then filed, on November 25, 2013, an Extraordinary Appeal aiming the decision rendered by Brazilian Superior Court of Justice to be reviewed by Brazilian Federal Supreme Court. On February 21, 2014, Brazilian subsidiaries presented its response to Citizen’s Extraordinary Appeal. On March 10, 2014, Citizen’s extraordinary appeal was not accepted by the Brazilian Superior Court of Justice and, on March 26, 2014, Citizen filed an appeal against such decision, aiming at its Extraordinary Appeal to be accepted and ruled by Brazilian Federal Supreme Court. On May 5, 2014 the Company presented its response to Citizen’s appeal to The Brazilian Federal Supreme Court. As of the date of this report the lower court’s ruling was still pending. In the opinion of the Company’s management and its legal counsel the risk of loss is reasonably possible but not probable.
	State of São Paulo Fraud Claim
	On June 12, 2007, a state prosecutor of the State of São Paulo, Brazil presented a claim against the Company’s Brazilian subsidiary. The state prosecutor alleges that the Brazilian subsidiary should be held liable for any fraud committed by sellers on the Brazilian version of the Company’s website, or responsible for damages suffered by buyers when purchasing an item on the Brazilian version of the MercadoLibre website. On June 26, 2009, the Lower Court Judge ruled in favor of the State of São Paulo prosecutor, declaring that the Brazilian subsidiary shall be held joint and severally liable for fraud committed by sellers and damages suffered by buyers when using the website, and ordering the Brazilian subsidiary to remove from the Terms of Service of the Brazilian website any provision limiting the Company’s responsibility, with a penalty of approximately $2,500 per day of non-compliance. On June 29, 2009 the Company presented recourse to the lower court, which was not granted. On September 29, 2009 the Company presented an appeal and requested to suspend the effects of the ruling issued by the lower court until the appeal is decided by State Court of Appeals, which request was granted on December 1, 2009. On May 23, 2014 the State Court of Appeals issued its ruling stating that MercadoLivre shall not be held responsible for the quality, nature or defective products or services purchased through the Brazilian website. While the decision is not clear, it could be understood that the State Court of Appeals ruled that MercadoLivre could be held joint and severally liable for fraud committed by sellers buyers when using the website. On June 13, 2014, MercadoLivre filed a motion to clarify the decision. On October 6, 2014, the State Court of Appeals overruled MercadoLivre’s motion to clarify its decision. The Company appealed the decision to the Brazilian Federal Superior Court of Justice. In the opinion of our management and its legal counsel the risk of loss is possible.

	In 2007 São Paulo tax authorities have asserted taxes and fines against our Brazilian subsidiary relating to the period from 2005 to 2007 in an approximate amount of $5.9 million according to the exchange rate in effect at that time. In 2007, the Company presented administrative defenses against the authorities’ claim and the tax authorities ruled against the Brazilian subsidiary. In 2009, the Company presented an appeal to the Conselho Municipal de Tributos or São Paulo Municipal Council of Taxes which reduced the fine. On February 11, 2011, the Company appealed this decision to the Câmaras Reunidas do Egrégio Conselho Municipal de Tributos or Superior Chamber of the São Paulo Municipal Council of Taxes which affirmed the reduction of the fine. As of the date of these financial statements, the total amount of the claim is approximately $4.8 million including surcharges and interest. With this decision the administrative stage is finished. On August 15, 2011, the Company made a deposit in court of approximately R$ 9.5 million, which including accrued interests amounted to R$ 10.4 million or $4.2 million, according to the exchange rate at September 30, 2014, and filed a lawsuit in 8th Public Treasury Court of the County of São Paulo, State of São Paulo, Brazil, to contest the taxes and fines asserted by the Tax Authorities. As of September 30, 2014, the 8th Public Treasury Court of the County of São Paulo ruling was still pending.
	In September 2012 São Paulo tax authorities have asserted taxes and fines against our Brazilian subsidiary related to our Brazilian subsidiary’s activities in São Paulo for the period from 2007 through 2010. On July 27, 2012, the Company presented administrative defenses against the authorities’ claim. On February 2, 2013, São Paulo tax authorities ruled against the Brazilian subsidiary maintaining claimed taxes and fines. On March 4, 2013, the Company presented an appeal to the Conselho Municipal de Tributos or São Paulo Municipal Council of Taxes. On August 23, 2013, the Câmaras Reunidas do Egrégio Conselho Municipal de Tributos or Superior Chamber of the São Paulo Municipal Council of Taxes ruled against the Company’s appeal. On September 5, 2013, the Company presented a special appeal to the Superior Chamber of the São Paulo Municipal Council of Taxes. On October 18, 2013, the mentioned appeal was denied to our Brazilian subsidiary and confirmed the fines. With this decision the administrative stage is finished. On November 13, 2013, the Company filed a lawsuit before the 9th Treasury Court of the City of São Paulo, State of São Paulo, Brazil, to contest the taxes and fines asserted by the Tax Authorities. On November 14, 2013, the Company made a deposit in court related to the lawsuit filed, of approximately R$41 million or $16.7 million, according to the exchange rate at September 30, 2014. On January 28, 2014 São Paulo Municipal Council was summoned and on April 8, 2014 the São Paulo Municipal Council presented its defense. On April 24, 2014 the Company presented its response to the mentioned defense. As of September 30, 2014, the lower court’s ruling was still pending.

	In January 2005 the Brazilian subsidiary moved its operations to Santana de Parnaíba City, Brazil and began paying taxes to that jurisdiction and therefore the Company believes that has strong defenses to the claims of the São Paulo authorities with respect to these periods.
	The Company’s management and its legal counsel believe that the risk of loss is remote, and as a result, has not reserved any provisions for these claims.
	The collection date of the legal deposits cannot be determined since it will depend on the actual duration of the related legal proceedings.
	State of Rio Grande do Sul Service Claim
	On November 20, 2013, a state prosecutor of the County of Porto Alegre, State of Rio Grande do Sul, Brazil, presented a claim against our Brazilian subsidiary before the 15th Civil Court of Porto Alegre, State of Rio Grande do Sul, Brazil. The state prosecutor alleged that MercadoLivre should be held liable for any offer or sale of any unlawful products or services through its website. A preliminary injunction was granted on November 25, 2013 ordering the Brazilian subsidiary to monitor and prevent any offer of unlawful products or services. On January 22, 2014, the Brazilian subsidiary was summoned. On March 11, 2014, the Company presented its defense. On March 24, 2014, the Company filed an appeal against the preliminary injunction before the State Court of Rio Grande do Sul, Brazil, and on March 26, 2014 it was granted a motion to stay, revoking temporarily the effects of the injunction until the final ruling of the Interlocutory Appeal. As of the date of this report the Interlocutory Appeal of the Brazilian subsidiary was not yet ruled by the State Court of Rio Grande do Sul, Brazil and the lower court’s proceeding was suspended, awaiting for mentioned ruling by the State Court. In the opinion of the Company’s management the risk of losing the case is reasonably possible, but not probable.
	Argentine Labor Union Claim
	On September 29, 2014, the Argentina union of Commercial Labor Union “Federación Argentina de Empleados de Comercio y Servicios” (“Sindicato de Comercio” or the “Plaintiff”) filed a lawsuit against the Company’s Argentine subsidiary, MercadoLibre S.R.L. (“MercadoLibre” or the “Company”), in the First Instance National Court on Labor Matters Number Fifty Eight of Buenos Aires, Argentina (the “Court”). The Plaintiff seeks the payment of allegedly unpaid monthly obligations due for employees for the last 10 years, for AR$ 3.2M plus interests and legal expenses. The deadline to file the defense of MercadoLibre is actually suspended because the Company is trying to arrive to a settlement. As of the date of this report, according to the opinion of the Company’s management and its external legal counsel, the Company has recorded a provision for the amount that has been considered as a probable amount of settlement.

	Other third parties have from time to time claimed, and others may claim in the future, that the Company was responsible for fraud committed against them, or that the Company has infringed their intellectual property rights. The underlying laws with respect to the potential liability of online intermediaries like the Company are unclear in the jurisdictions where the Company operates. Management believes that additional lawsuits alleging that the Company has violated copyright or trademark laws will be filed against the Company in the future.
	Intellectual property and regulatory claims, whether meritorious or not, are time consuming and costly to resolve, require significant amounts of management time, could require expensive changes in the Company’s methods of doing business, or could require the Company to enter into costly royalty or licensing agreements. The Company may be subject to patent disputes, and be subject to patent infringement claims as the Company’s services expand in scope and complexity. In particular, the Company may face additional patent infringement claims involving various aspects of the payments businesses.
	From time to time, the Company is involved in other disputes or regulatory inquiries that arise in the ordinary course of business. The number and significance of these disputes and inquiries are increasing as the Company’s business expands and the Company grows larger.

	8	Long term retention plan
	On March 31, 2014, the Board of Directors, upon the recommendation of the Compensation Committee approved the 2014 employee retention programs (“2014 LTRP”). The awards under 2014 LTRP are payable in cash, common stock or a combination thereof, in addition to the annual salary and bonus of each employee. The Company has granted the right to any LTRP participant to request settlement in cash.
	The 2014 LTRP will be paid in 6 equal annual quotas (16.67% each) commencing on March 31, 2015. Each quota is calculated as follows:

		•		8.333% of the amount is calculated in nominal terms (“the nominal basis share”),

		•		8.333% is adjusted by multiplying the nominal amount by the average closing stock price for the last 60 trading days of the year previous to the payment date and divided by the average closing stock price for the last 60 trading days of 2013. The average closing stock price for the 2014 LTRP amounted to $118.48 (“the variable share”).

	The following tables summarize the 2009, 2010, 2011, 2012, 2013 and 2014 LTRP accrued compensation expense for the nine and three-month periods ended September 30, 2014 and 2013:

Debt Disclosure [Abstract]	'
2.25% Convertible Senior Notes Due 2019	'
	9	2.25% Convertible Senior Notes Due 2019
	On June 30, 2014, the Company issued $330 million of 2.25% convertible senior notes due 2019 (the “Notes”). The Notes are unsecured, unsubordinated obligations of the Company, which pay interest in cash semi-annually, on January 1 and July 1, at a rate of 2.25% per annum. The Notes will mature on July 1, 2019 unless earlier repurchased or converted in accordance with their terms prior to such date. The Notes may be converted, under the conditions specified below, based on an initial conversion rate of 7.9353 shares of common stock per $1,000 principal amount of Notes (equivalent to an initial conversion price of approximately $126.02 per share of common stock), subject to adjustment as described in the indenture governing the Notes. The net proceeds from the Notes were approximately $322 million, net of the transaction costs.
	Holders may convert their notes at their option at any time prior to January 1, 2019 only under the following circumstances: (1) during any calendar quarter commencing after the calendar quarter ending on September 30, 2014 (and only during such calendar quarter), if the last reported sale price of the common stock for at least 20 trading days (whether or not consecutive) during a period of 30 consecutive trading days ending on the last trading day of the immediately preceding calendar quarter is greater than or equal to 130% of the conversion price on each applicable trading day; (2) during the five business day period after any five consecutive trading day period (the “measurement period”) in which the trading price per $1,000 principal amount of notes for each trading day of the measurement period was less than 98% of the product of the last reported sale price of our common stock and the conversion rate on each such trading day; or (3) upon the occurrence of specified corporate events. On or after January 1, 2019 until the close of business on the second scheduled trading day immediately preceding the maturity date, holders may convert their notes at any time, regardless of the foregoing circumstances. Upon conversion, the Company will pay or deliver, as the case may be, cash, shares of our common stock or a combination of cash and shares of our common stock, at our election.

	As of September 30, 2014, none of the conditions allowing holders of the Notes to convert had been met.
	In accordance with ASC 470-20 Debt with Conversion and Other Options, the convertible debt instrument within the scope of the cash conversion subsection, was separated into debt and equity components at issuance and be assigned a fair value. The value assigned to the debt component is the estimated fair value, as of the issuance date, of a similar debt without the conversion feature. As of June 30, 2014, the Company determined the fair value of the liability component of the Notes by reviewing market data that was available for senior, unsecured nonconvertible corporate bonds issued by comparable companies. Assumptions used in the estimate represent what market participants would use in pricing the liability component, including market interest rates, credit standing, and yield curves, all of which are defined as level 2 observable inputs. The difference between the cash proceeds and this estimated fair value, represents the value assigned to the equity component and is recorded as a debt discount. The debt discount is amortized using the effective interest method from the origination date through its stated contractual maturity date.
	The initial debt component of the Notes was valued at $283,015,125, based on the contractual cash flows discounted at an appropriate market rate for a non-convertible debt at the date of issuance, which was determined to be 5.55%. The carrying value of the permanent equity component reported in additional paid-in-capital was initially valued at $46,984,875. The effective interest rate after allocation of transaction costs to the liability component is 6.10% and is used to amortize the debt discount and transaction costs. Additionally, the Company recorded a deferred tax liability related to the additional paid in capital component of the convertible notes amounting to $16,444,706.
	The following table presents the carrying amounts of the liability and equity components:


			September 30, 2014
	Amount of the equity component (1)		$	45,807,685

	2.25% convertible senior notes due 2019		$	330,000,000

	-2	As of September 30, 2014, the remaining period over which the unamortized debt discount will be amortized is 4.75 years.

	The following table presents the interest expense for the contractual interest and the accretion of debt discount:

	Amortization of debt issuance costs			282,406

	Total interest expense related to Notes		$	4,209,241

	Capped call transactions
	The net proceeds from the Notes were approximately $321,731,960, after considering the transaction costs in an amount of $8,268,040. In connection with the issuance of the Notes, the Company paid $19,668,000 to enter into capped call transactions with respect to its common shares (the “Capped Call Transactions”), with certain financial institutions. The Capped Call Transactions are expected generally to reduce the potential dilution upon conversion of the Convertible Notes and / or offset any cash payments the Company may be required to make in excess of the principal amount of any converted notes in the event that the market price of the common shares is greater than the strike price of the Capped Call Transactions, initially set at $126.02 per common share, which corresponds to the initial conversion price of the Notes and is subject to anti-dilution adjustments substantially similar to those applicable to the conversion rate of the Notes, and have a cap price of approximately $155.81 per common share. Therefore, as a result of executing the Capped Call Transactions, the Company will reduce its exposure to potential dilution once the market price of its common shares exceeds the strike price of $126.02 and up to a cap price of approximately $155.81 per common share. The Capped Call Transactions allow us to receive shares of our common stock and/or cash related to the excess conversion value that the Company would pay to the holders of the Notes upon conversion, up to the above mentioned cap price.
	The $19,668,000 cost of the capped call transactions, which net of deferred income tax effect amounts to $12,784,200, is included as a net reduction to additional paid-in capital in the stockholders’ equity section of these interim condensed consolidated balance sheets, in accordance with the guidance in ASC 815-40 Derivatives and Hedging-Contracts in Entity’s Own Equity.

	11	New Law of “Costs, Earnings, and Fair Profits”
	In November 2013 the Venezuelan Congress approved an “enabling law” granting the president of Venezuela the authority to enact laws and regulations in certain policy areas by decree. This authority includes the ability to restrict profit margins and impose greater controls on foreign exchange and the production, import, and distribution of certain goods. Among other actions, the president has used this decree power to pass the Law of Costs, Earnings, and Fair Profits, which became effective in January 2014 and, among other provisions, authorizes the Venezuelan government to set “fair prices” and maximum profit margins in the private sector. Management of the Company estimates that this new law will not have a significant effect in 2014 as a consequence of losses incurred in the Venezuelan segment during this year. In addition, management of the Company will continue monitoring the potential effects of this new law in the future.

	Basis of presentation
	The accompanying unaudited interim condensed consolidated financial statements are prepared in conformity with accounting principles generally accepted in the United States of America (U.S. GAAP) and include the accounts of the Company and its wholly-owned subsidiaries. Ownership interests of minority interests are recorded as noncontrolling interest. These interim condensed consolidated financial statements are stated in U.S. dollars. Intercompany transactions and balances have been eliminated for consolidation purposes.
	Substantially all net revenues, cost of net revenues and operating expenses, are generated in the Company’s foreign operations, amounting to approximately 99.7% and 99.6% of the consolidated amounts during the nine-month periods ended September 30, 2014 and 2013. Long-lived assets and Goodwill located in the foreign operations totaled $162,744,933 and $183,922,432 as of September 30, 2014 and December 31, 2013, respectively.

	These interim condensed consolidated financial statements reflect the Company’s consolidated financial position as of September 30, 2014 and December 31, 2013. These financial statements also show the Company’s consolidated statements of income, of comprehensive income for the nine-month and three-month periods ended September 30, 2014 and 2013, and statement of cash flows for the nine-month periods ended September 30, 2014 and 2013. These interim condensed consolidated financial statements include all normal recurring adjustments that management believes are necessary to fairly state the Company’s financial position, operating results and cash flows.
	Because all of the disclosures required by U.S. GAAP for annual consolidated financial statements are not included herein, these unaudited interim condensed financial statements should be read in conjunction with the audited consolidated financial statements and the notes thereto for the year ended December 31, 2013, contained in the Company’s Annual Report on Form 10-K filed with the Securities and Exchange Commission (“SEC”). The condensed consolidated statements of income, of comprehensive income and of cash flows for the periods presented herein are not necessarily indicative of results expected for any future period.
Foreign Currency Translation	'
	Foreign currency translation
	Venezuelan currency status
	All of the Company’s foreign operations have determined the local currency to be their functional currency, except for Venezuela since January 1, 2010, as described below. Accordingly, these foreign subsidiaries translate assets and liabilities from their local currencies into U.S. dollars by using the period-end exchange rates while income and expense accounts are translated at the average rates in effect during the period, unless exchange rates fluctuate significantly during the period, in which case the exchange rates at the date of the transaction are used. The resulting translation adjustment is recorded as a component of other comprehensive income (loss). Gains and losses resulting from transactions denominated in non-functional currencies are recognized in earnings.
	According to U.S. GAAP, the Company has transitioned its Venezuelan operations to highly inflationary status as from January 1, 2010, which requires that transactions and balances are re-measured as if the U.S. dollar were the functional currency for such operation.
	On February 9, 2013, the Venezuelan Central Bank (“BCV”) eliminated the SITME and devalued the official exchange rate used to re-measure our Venezuelan subsidiaries’ non-U.S. dollar denominated monetary assets and liabilities as from February 9, 2013 to 6.3 BsF (Bolivares Fuertes) per U.S. dollar. The effect of using the devalued official rate of 6.3 BsF per U.S. dollar generated a foreign currency loss that amounted to $6.4 million in the first quarter of 2013.
	On March 19, 2013, the BCV announced the creation of the Sistema Complementario de Administración de Divisas (SICAD 1), which acts jointly with the Commission for the Administration of Foreign Exchange Control (CADIVI). In order to operate within this system, a company should be registered at the Registro Automatizado (Automatized Register, or RUSAD). The acquisition of foreign currencies under this system is organized under an auction process to obtain foreign currencies for payments to foreign suppliers, where the minimum exchange rate to be offered is 6.3 BsF per U.S. dollar.
	During December 2013, the Venezuelan regulation that created the SICAD 1 was amended to expand its use, and to require publication of the average exchange rate implied by transactions settled in SICAD 1 auctions. Additionally, on January 23, 2014, the exchange regulation was amended to include foreign currency sales for certain transactions, such as but not limited to: contracts for leasing and services, use and exploitation of patents, trademarks, foreign investments and payments of royalties, contracts for technology import and technical assistance. Due to the change in rules that provided for the creation of the SICAD 1 system, the official exchange rate remains only available to obtain foreign currency to pay for a limited list of goods considered to be of high priority by the Government, which does not include those relating to the Company’s business. As a consequence, SICAD 1 became, from that moment, the primary system to which the Company would have to request U.S. dollars to settle its transactions. As a result, from January 24 to May 15, 2014, the exchange rate used to re-measure the Company’s net monetary asset position in BsF and BsF transactions of its Venezuelan operations was the SICAD 1 exchange rate.
	In late February 2014, the Venezuelan government issued a decree to open a new exchange control mechanism (“SICAD 2”) that should allow the purchase of foreign exchange currencies, through authorized foreign exchange operators offered by individuals and companies such as Petróleos de Venezuela, S.A. (PDVSA, the oil state-owned corporation of Venezuela), the BCV and other public entities authorized by the Ministry of Finance. The Venezuelan government has published operating rules for the new exchange mechanism in Exchange Agreement N° 27, and SICAD 2 began operating on March 24, 2014. Since implementation of the SICAD 1 system, the Company was unsuccessful in gaining access to U.S. dollars through SICAD 1. As a result of this ongoing lack of access to the SICAD 1 auction system, on May 16, 2014, the Company decided to start requesting U.S. dollars through the SICAD 2 mechanism. The SICAD 2 system is an open mechanism that permits any company to request dollars for any purpose. Consequently, the Company is eligible for and has been granted, U.S. dollars through the SICAD 2 mechanism.
	As a consequence of the determination to obtain U.S. dollars through SICAD 2 and the lack of access to SICAD 1 since May 16, 2014, the Company concluded that the SICAD 2 exchange rate should be used to re-measure their bolivar-denominated monetary assets and liabilities in BsF and to re-measure the results of its Venezuelan operations, effective as of May 16, 2014. As a consequence, the Company has recorded a foreign exchange loss of $16.5 million during the second quarter of 2014. As of September 30, 2014 the SICAD 2 exchange rate was 49.99 BsF per U.S. dollar.

	In light of the current economic conditions in Venezuela, and the determination to access SICAD 2 and re-measure the BsF denominated monetary assets and liabilities of its Venezuelan subsidiaries, and the lower U.S. dollar-equivalent cash flows now expected from the Venezuelan business, the Company reviewed the long-lived assets, goodwill and intangible assets with indefinite useful life for impairment, including considering the current expected use of these assets in light of this foregoing. The Company owns two office spaces in Venezuela that had expected to use to support the main operating activities in that country. However, due to the current conditions, the Company now intends to rent these office spaces to third parties to generate rental income and will consider opportunities for disposal of these assets if real estate market conditions are favorable. Because the Company has concluded that the carrying value of these two real estate properties will not be recoverable, it has recorded an impairment of long-lived assets of $49,495,686 during May 2014. The carrying amount has been adjusted to its estimated fair value of approximately $22 million.
	Until 2010 the Company was able to obtain U.S. dollars for any purpose, including dividends distribution, using alternative mechanisms other than through the CADIVI. Those U.S. dollars, obtained at a higher exchange rate than the one offered by CADIVI, and held in balance at U.S. bank accounts of our Venezuelan subsidiaries, were used for dividend distributions from our Venezuelan subsidiaries. Our Venezuelan subsidiaries have not requested authorization since 2012 to acquire U.S. dollars to make dividend distributions. The Company has not distributed dividends from our Venezuelan subsidiaries since 2011.
	The following table sets forth the assets, liabilities and net assets of the Company’s Venezuelan subsidiaries, before intercompany eliminations, as of September 30, 2014 and December 31, 2013 and net revenues for the nine-month periods ended September 30, 2014 and 2013:


		Nine-month periods ended September 30,
		2014			2013
	Venezuelan operations
	Net Revenues	$	45,184,278		$	55,695,385


		September 30,			December 31,
		2014			2013
	Assets		65,444,729			126,873,804
	Liabilities		(38,504,273	)		(62,437,338	)

	Net Assets	$	26,940,456		$	64,436,466

	As of September 30, 2014, net assets (before intercompany eliminations) of the Venezuelan subsidiaries amounted to approximately 7.9% of consolidated net assets, and cash and investments of the Venezuelan subsidiaries held in local currency in Venezuela amounted to approximately 2.3% of our consolidated cash and investments.

	The Company’s ability to obtain U.S. dollars in Venezuela is negatively affected by the exchange regulations in Venezuela that are described above and elsewhere in these financial statements. In addition, its business and ability to obtain U.S. dollars in Venezuela would be negatively affected by additional material devaluations or the imposition of significant additional and more stringent controls on foreign currency exchange by the Venezuelan government.
	Despite the current difficult macroeconomic environment in Venezuela, the Company continues to actively manage, through its Venezuelan subsidiaries, its investment in Venezuela. Regardless the current operating, political and economic conditions and certain other factors in Venezuela, management currently plans to continue supporting its business in Venezuela in the long run.
	Argentine currency status
	The Argentine government has implemented certain measures that control and restrict the ability of companies and individuals to exchange Argentine pesos for foreign currencies. Those measures include, among other things, the requirement to obtain the prior approval from the Argentine Tax Authority of the foreign currency transaction (for example and without limitation, for the payment of non-Argentine goods and services, payment of principal and interest on non-Argentine debt and also payment of dividends to parties outside of the country), which approval process could delay, and eventually restrict, the ability to exchange Argentine pesos for other currencies, such as U.S. dollars. Those approvals are administered by the Argentine Central Bank through the Local Exchange Market (“Mercado Unico Libre de Cambios”, or “MULC”), which is the only market where exchange transactions may be lawfully made.
	Further, restrictions also currently apply to the acquisition of any foreign currency for holding as cash within Argentina. Although the controls and restrictions on the acquisition of foreign currencies in Argentina place certain limitations on our current ability to convert cash generated by our Argentine subsidiaries into foreign currencies, based on the current state of Argentine currency rules and regulations, we do not expect that the current controls and restrictions, will have a material adverse effect on our business plans in Argentina or on our overall business, financial condition or results of operations.
	Additionally, during January 2014 the Argentinean peso exchange rate against the U.S. dollar increased in approximately 23%, from 6.52 Argentinean Pesos per U.S. dollar as of December 31, 2013 to approximately 8.0 Argentinean Pesos per U.S. dollar. Due to the abovementioned devaluation, during the first quarter of 2014, the reported net assets in Argentina decreased in $14,625,451 with the related impact in Other Comprehensive Income and the Company recognized a foreign exchange gain of $4,597,510. As of September 30, 2014, the Argentinean Peso exchange rate was $8.43 per U.S. dollar.
Income Tax Holiday in Argentina	'
	Income Tax Holiday in Argentina
	According to Argentine law, from fiscal year 2008, the Company’s Argentine subsidiary has been a beneficiary of a software development law. Part of the benefits obtained from being a beneficiary of the aforementioned law is a relief of 60% of total income tax determined in each year, thus resulting in an effective tax rate in Argentina lower than the income tax law statutory rate. The law expired on September 17, 2014. As a consequence, the average tax rate for 2014 would be approximately 22% as we expect no income tax holiday during last quarter of fiscal year 2014.
	Aggregate tax benefit totaled $2,044,806 and $2,973,762 for the three-month periods ended September 30, 2014 and 2013, respectively, while for the nine-month periods ended at such dates amounted to $5,643,975 and $7,742,787, respectively. Aggregate per share effect of the Argentine tax holiday amounted to $0.05 and $0.07 for the three-month periods ended September 30, 2014 and 2013, respectively, while for the nine-month periods ended at such dates amounted to $0.13 and $0.18, respectively.
	In addition, during fiscal year 2013 the Company acquired a software development company (see Note 4), located in the Province of Cordoba, Argentina, which is also beneficiary of the aforementioned income tax holiday, however the total benefit obtained is immaterial.
	If the Company had not been granted the Argentine tax holiday, it would have pursued an alternative tax planning strategy and, therefore, the impact of not having this particular benefit would not necessarily be the abovementioned dollar and per share effect.
	On August 17, 2011, the Argentine government issued a new software development law and on September 9, 2013 the regulatory decree was issued, which established the new requirement to become beneficiary of the new software development law. The new decree establishes compliance requirements with annual incremental ratios related to exports of services and research and development expenses that must be achieved to remain within the tax holiday. The Argentine operation will have to achieve certain required ratios annually under the new software development law.
	If we are successful in being admitted as beneficiaries under the new law, the current income tax relief would decrease, but it is currently estimated that the Argentine effective income tax rate would still be materially lower than the statutory income tax rate. Also, the tax holiday under the new law would last until 2019.
	The Industry Secretary resolution which rules, among other provisions, on the mechanism to file the information to obtain the benefits derived from the new software development law was issued in late February 2014. During May 2014, the Company presented all the required documentation in order to apply for the new software development law. At the date of issuance of these interim condensed consolidated financial statements, the Industry Secretary resolution which approves the Company’s application is still pending.

Impairment of Long-lived Assets	'
	Impairment of long-lived assets
	The Company reviews its long-lived assets for impairment whenever events or changes in circumstances indicate that the carrying value of an asset may not be recoverable.

	As explained in the section “Foreign Currency Translation” of the present Note to these interim condensed consolidated financial statements, as a consequence of an ongoing lack of access to SICAD 1 auction system, on May 16, 2014 the Company decided to start requesting U.S. dollars through the SICAD 2 mechanism and use the SICAD 2 exchange rate to re-measure its Bolivar-denominated monetary assets and liabilities in BsF and to re-measure the result of its Venezuelan operations, effective as of May 16, 2014.
	Considering this change in facts and circumstances and the lower U.S. dollar-equivalent cash flows now expected from our Venezuelan business, and their expected current use in the new context (receive rental income instead of using the long-lived assets to support the Company’s future growth of operations in Venezuela), the Company compared the carrying amount of the long-lived assets with the expected undiscounted future net cash flows and concluded that two office spaces held in Caracas, Venezuela, should be impaired. As a consequence, the Company estimated the fair value of the impaired long-lived assets and recorded an impairment loss of $49,495,686 during the second quarter of 2014.
Convertible Senior Notes	'
	Convertible Senior Notes
	On June 30, 2014, the Company issued $330 million of 2.25% convertible senior notes due 2019 (the “Notes”). The Notes are unsecured, unsubordinated obligations of the Company, which pay interest in cash semi-annually, on January 1 and July 1, at a rate of 2.25% per annum. The Notes will mature on July 1, 2019 unless earlier repurchased or converted in accordance with their terms prior to such date. The Notes may be converted, under specific conditions, based on an initial conversion rate of 7.9353 shares of common stock per $1,000 principal amount of Notes (equivalent to an initial conversion price of approximately $126.02 per share of common stock), subject to adjustment as described in the indenture governing the Notes.
	Prior to January 1, 2019, the Notes will be convertible only upon the occurrence of certain events and during certain periods, and thereafter, at any time until the close of business on the second scheduled trading day immediately preceding the maturity date of the Notes. The conversion rate is subject to customary anti-dilution adjustments. Following certain corporate events described in the Indenture that occur prior to the maturity date, the conversion rate will be increased for a holder who elects to convert its Notes in connection with such corporate event in certain circumstances. The Indenture contains customary terms and covenants, including that upon certain events of default occurring and continuing, either the Trustee or the holders of at least 25% in principal amount of the outstanding Notes may declare 100% of the principal of, and accrued and unpaid interest on, all the Notes to be due and payable.
	In accordance with ASC 470-20 Debt with Conversion and Other Options, the convertible debt instrument within the scope of the cash conversion subsection, was separated into debt and equity components at issuance and a fair value was assigned. The value assigned to the debt component was the estimated fair value, as of the issuance date, of a similar debt without the conversion feature. As of the issuance date, the Company determined the fair value of the liability component of the Notes based on market data that was available for senior, unsecured nonconvertible corporate bonds issued by comparable companies. The difference between the cash proceeds and this estimated fair value, represents the value assigned to the equity component and was recorded as a debt discount. The debt discount is amortized using the effective interest method from the origination date through its stated contractual maturity date.
	The initial debt component of the Notes was valued at $283,015,125, based on the contractual cash flows discounted at an appropriate market rate for a non-convertible debt at the date of issuance, which was determined to be 5.55%. The carrying value of the permanent equity component reported in additional paid-in-capital was initially valued at $46,984,875. The effective interest rate after allocation of transaction costs to the liability component is 6.10% and is used to amortize the debt discount and transaction costs.
	In connection with the issuance of the Notes, the Company paid approximately $19,668,000 to enter into capped call transactions with respect to its common shares (the “Capped Call Transactions”), with certain financial institutions. The Capped Call Transactions are expected generally to reduce the potential dilution upon conversion of the Convertible Notes and / or offset any cash payments the Company may be required to make in excess of the principal amount of any converted notes in the event that the market price of the common shares is greater than the strike price of the Capped Call Transactions, initially set at $126.02 per common share, which corresponds to the initial conversion price of the Notes and is subject to anti-dilution adjustments substantially similar to those applicable to the conversion rate of the Notes, and have a cap price of approximately $155.81 per common share.
	The $19,668,000 cost of the capped call transactions, which net of deferred income tax effect amounts to $12,784,200, is included as a net reduction to additional paid-in capital in the stockholders’ equity section of our consolidated balance sheets.
	For more detailed information in relation to the Notes and the Capped Call transactions, see Note 9 to these interim condensed consolidated financial statements.
Use of Estimates	'
	Use of estimates
	The preparation of interim condensed consolidated financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Estimates are used for, but not limited to accounting for allowance for doubtful accounts and chargeback provisions, depreciation, amortization, recoverability of goodwill and intangible assets with indefinite useful life, useful life of long-lived assets, impairment of short-term and long-term investments, impairment of long-lived assets, compensation costs, relating to the Company’s long term retention plan, fair value of convertible debt note, recognition of income taxes and contingencies. Actual results could differ from those estimates.
Recently Issued Accounting Pronouncements	'
	Recently issued accounting pronouncements
	In April 2014, the FASB issued the Accounting Standards Update (“ASU”) N° 2014-8, “Reporting Discontinued Operations and Disclosures of Disposals of Components of an Entity”, which changes the criteria for determining which disposals can be presented as discontinued operations and modifies related disclosure requirements. Under the ASU, only disposals that represent a strategic shift that has (or will have) a major effect on the entity’s results and operations would qualify as discontinued operations. In addition, the ASU (1) expands the disclosure requirements for disposals that meet the definition of s discontinued operation, (2) requires entities to disclose information about disposals of individually significant components, and (3) defines “discontinued operations” similarly to how it is defined under IFRS 5, “Non-current Assets Held for Sale and Discontinued Operations”. The standard is required to be adopted in annual periods beginning on or after December 15, 2014, and interim periods within those annual periods. Early adoption is permitted, but only for disposals (or classifications as held for sale) that have not been reported in financial statements previously issued or available for issuance. The Company does not anticipate that this adoption will have a significant impact on its financial position, results of operations or cash flows.
	On May 28, 2014, the FASB issued the Accounting Standard Update (“ASU”) N° 2014-09, “Revenue contracts with clients”, which changes in the timing of revenue recognition, includes variable consideration in the transaction price prior to resolution of contingencies, allocates the transaction price based on standalone selling price, among other changes. This standard is required to be adopted for annual reporting periods beginning after December 15, 2016 for public entities, no early adoption is permitted. The Company is assessing the effects that the adoption of this accounting pronouncement will have on the Company’s financial position, results of operations or cash flows.
	In August 2014, the FASB issued new guidance related to the disclosures around going concern. The new standard provides guidance around management’s responsibility to evaluate whether there is substantial doubt about an entity’s ability to continue as a going concern and to provide related footnote disclosures. The new standard is effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2016. Early adoption is permitted. The adoption of this standard is not expected to have a material impact the Company’s financial statements.

'From fiscal year 2008, the Companybs Argentine subsidiary has been a beneficiary of a software development law. Part of the benefits obtained from being a beneficiary of the aforementioned law is a relief of 60% of total income tax determined in each year, thus resulting in an effective tax rate in Argentina lower than the income tax law statutory rate. The law expired on September 17, 2014. As a consequence, the average tax rate for 2014 would be approximately 22% as we expect no income tax holiday during last quarter of fiscal year 2014.
